MEANS FOR SUSTAINING SLIDING DOORS.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed February 10, 1910. Serial No. 543,180.

. a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Means for Sustaining Sliding Doors, of which the following is a specification, reference being had to the accompanying drawings.

This invention has for its leading object to provide improved means for sustaining in place and in operative position sliding doors or other reciprocatable embers.

In-carrying out my invention I employ a flexible connection that is secured at its ends to suitable supports adjacent to the lines of travel of the upper and lower edges respectively of the door or other reciprocatable member, and providing such door or member at points near its said upper and lower edges with guiding devices (best made in the form of pulleys) around which said flexible connection is led prior to being se cured in place. By experience I have found that the flexible connection is best made of a ribbon-like steel band or strip, and that for satisfactory results it must be secured at its ends in such manner as to be permitted sufficient lateral swing to enable it at all times to run absolutely true and smoothly over the guiding pulleys. As a further means of insuring such perfect working of the device I have found that one of the said guiding pulleys should be flexibly connected with the door so as to be permitted a slight lateral rocking or turning as on a swivel, whereby it will always aline itself with the other pulley.

To provide constructions permitting the securing of these ends are some of the objects of my invention.

Other objects of the invention are to provide novel means for adjustably holding one end of the said flexible connection; to provide novel means for detachably securing the lower one of said guiding pulleys to the door, and to provide in connection therewith means for vertically raising and lowering the door as required; to provide to improve generally the supporting of doors and other reciprocatable devices.

I accomplish these objects by the means shown in the drawings and hereinafter specifically described.

That which I believe to be new will be pointed out in the claims.

In the drawings I have shown my invention applied to an ordinary sliding door such as is commonly employed in dwellings and other buildings, and while the word door is therefore necessarily employed in describing the construction shown it is to be understood that it is only so used for convenience in this connection and that the invention is not intended to be limited to such particular use.

In the drawings,Figure 1 is a side elevation of an ordinary sliding door provided with my improved sustaining devices, the frame of the doorway also being shown. At the right hand side of this doorway is the pocket into which the door is moved to open the doorway, one of the walls of the pocket being broken away as shown. Fig. 2 is an enlarged detail of the rear upper corner portion of the door shown in Fig. 1 and showing the manner of attaching to the door the upper one of the two guiding pulleys, a portion of the flexible connection being shown in dotted lines. Fig. 3 is a plan view of the upper guiding pulley and the means that connect it with the door. Fig. 4 is a detail, showing the means employed for securing in place the upper end of the flexible connection. Fig. 5 is a top or plan view of the parts shown in Fig. 4. Fig. 6 is an enlarged detail, showing the rear lower corner portion of the door and, partly in section, the means for detachably and adjustably securing the lower guiding pulley to the door. There is also shown in section the means for adjustably securing the lower end of the flexible connection. Fig. 7 is a top or plan view of the lower guiding pulley and the means for connecting the same to the door, a portion of the door being shown in section. Fig. 7 is a perspective view of the upper part of a door provided with my improvements and showing also the beam or strip that is removably secured over the door and which carries at one end the pivoted means to which the upper end of the which the lower end of the flexible connection is held.

Referring to the several figures of the drawings, in which corresponding parts are indicated by like reference numerals,20 indicates a sliding door of any ordinary construction adapted to close a doorway whose frame is indicated by 21. At one side of the doorway,-at the right-hand side as shown in Fig. 1,is the usual pocket into which the door is adapted to be moved to uncover the doorway. As shown in this figure, one wall of the pocket is broken away so as to show the su porting devices carried at the rear of the dbor.

22 indicates a flexible connection made fast at its ends to suitable devices, one of such ends being supported near the line of travel of the upper edge of the door while the other is supported near the line of travel of the lower edge of the door. This flexible connection passes over two guiding pulleys 23 and 24 each secured to the rear edge of the door and located respectively near the upper and lower ends of the door. As hereinbefore stated, this flexible connection has been found to be best made of a thin ribbonlike metal strip or band, and, being in that form, it is of very considerable importance that it be so secured in place at its ends that it will, if necessary, be permitted a slightlateral movement so that it will not tend to buckle or bend as it runs over the pulleys; it is also important in order to secure perfect freedom from such buckling or bending tendenc that one at least of the guiding pulleys ave such a connection with the door as to permit of a slight lateral turning or moving when necessary. In other words, it is important owin to the flexible connection being of this ribbon-like or strip form, to rovide means for compensating for any little departure that may occur from perfect alinement of the support for the ends with the pulleys.

Referring to the means for attaching the upper end of the connection, 25 indicates a bracket secured in place near the upper inner corner of the pocket into which the door slides, to the rear end of which bracket is attached by a pivot 26 a short arm 27 (see Fig. 4). The upper end of the flexible connection 22 lies against the under face of this arm 27 and is held secured thereto between such arm and a small plate 28 by screws or rivets '29. The forward end of the bracket 25 is turned down in a vertical position, as clearly shown in Fig. 4, to adapt it to receive and hold a suitable bumper 30 against which the rear edge of the door 20 can strike when the door is moved back to the limit of its movement in the pocket.

31 (see Figs. 1 and 7) indicates a beam or strip of wood fitting over the doorway and the upper end of the pocket, to which strip the bracket 25 is secured in the construct-ion shown. By providing this beam or strip 31, the bracket 25 can be attached to it before the beam or strip is inserted in place and thereby be placed in position, thus permitting the ready attachment of my invention to doors in houses already constructed. It also enables any one to have comparatively ready access to the bracket 25 for purposes of repair or otherwise, because this beam or strip can be easily removed. It is suflicient to secure it by screws through only that part that lies over the doorway as shown, and hence can be very readily placed in position or taken down.

32 indicates a support for the upper guiding pulley adapted to fit on the upper edge of the door 20, and, as shown, is long enough to extend beyond the stile and be secured to the upper rail of the door. This is desirable as it overcomes any tendency of the stile to separate from the upper rail which might otherwise occur owing to the strain imposed upon the parts, owing to the manner in which the door is supported. The rear end of the support 32, in the construction shown, is turned down and then outward at an angle, as clearly shown in Figs. 1 and 2, and this turned end is provided with a deep notch 33.

34 indicates a frame that embraces the guide pulleys 23 and in the sides of which frame is journaled the axle of such pulley. The end of the frame is provided with a stud 35 adapted to be slipped into the not-ch 33 in the up-turned portion of the support 32, the enlarged head of said stud resting on the face of said up-turned end and thus firmly but detachably holding the guiding pulley 23 in place. This attaches the guide pulley in place in a flexible manner and enables it to rock on the stud 35 as on a swivel.

Referring now to the lower guiding pulley 24 and its manner of attachment to the door, 36 indicates a frame the sides of which furnish bearings for the axle of said pulley 24. 37 indicates a corner iron secured against the rear and lower edges of the door. The vertical portion of this corner iron 37 is provided for the greater portion of its length with inturned side wings 38 which bear against the rear edge of the door and so leave a space between the body portion of the vertical member of the corner iron and the edge of the door in which is located a slide 39, best shown in Fig. 10. This slide is provided near its lower end with a stud 40 which projects through a slot 41 in the face of the vertical portion of the corner iron 37 and at its upper end is provided with an outwardly-turned lip 42 that projectsthrough a slot 43 in the face of said vertical portion of the corner iron 37. The edge face of the frame 36 is provided at its lower end with a notch 44 which engages the stud 40, the head of the stud holding the frame 36 in place. When the frame 36 is thus mounted on the stud 40, the lip 42 will rest in a small notch 45 (see Fig. 8) cut in the upper edge of the end of the frame 36 and thus prevent the frame from turning on'the stud. As best shown in Fig. 10, the slide 39 is provided with a slot 46 through which one of the holding screws that secure the corner piece 37 in place is adapted to pass. At its upper end, the corner piece is turned outward to form a bowed portion 47 through a screw-threaded opening in which passes a screw 48 by the turning of which the slide 39 can be forced down as desired, owing to the end of the screw bearing on the turned lip 42 at the upper end of the slide, thus causing a relative movement between the pulley frame and the corner iron 37, that results in an adjustment of the door.

49 indicates a plate secured beneath the door at about the entrance to the pocket hereinbefore referred to. It is pivotally attached at its outer end to a screw 50, or the equivalent thereof.

51 indicates a vertical lip struck up from the plate 49 through which loosely passes an adjusting screw 52. This screw operatively engages the end wall of a small casing 53, in which, at its other end, is located a steel roller 54 that is held from escaping from the open end of the casing by reason of the bottom of the casing being slightly upturned as indicated by 56. The end of the casing where the roller is located is open, as above stated, and the lower end of the flexible connection 22 can be inserted over the roller 54 and will be held there against withdrawal because any strain upon the con nection tending to withdraw it will cause the roller to move toward the open end of the casing and tightly grip such connection between it and the upper wall of the casing, the slightly up-turned end 56 of the bottom of the casing causing the roller to bear firmly against the flexible connection. At the end of the casing opposite to that in which theroller is located is a slot through which the flexible connection can pass to enable the person applying said connection to the door to grasp it so as to pull it as tightly as possible. It is evident that by turning the screw 52, the casing can be drawn along on the plate 49 toward the pivot of such plate and thereby complete the drawing up of the connect-ion to the required extent. It is of course designed to have the plate 49 located in exact alinement with the guide pulley 24, but if such exact alinement is not attained, that is compensated for by the slight lateral swing per mitted the plate by reason of its pivotal connection to the floor.

57 indicates a track rail in the pocket upon which the guide pulley 24 bears with a portion always of the flexible connection. 22 interposed between it and such guiding pulley.

In the use of this invention, the flexible connection is to be securely affixed to the pivoted arm 27 and then led over the upper guiding pulley 23, the frame of which, as explained, is swiveled in place. It is then led down and passed around and under the lower guiding pulley 24 and forward to the casing 53, the supporting plate 53 for which is, as stated, located on the 'floor adjacent to the mouth of the pocket into which the door slides when it is pulled back. After being led to this casing, the end of the flexible connection is inserted into the open end of the casing and over the roller 54 therein, and through the slot in the other end of the casing. It is then to be drawn up by hand,

the operator pulling on the end that will project through the slot as stated. Afterward such projecting end or such portion of it as is desired is to be cut or broken off. The exact adjustment of the door so as to bring its lower edge horizontal is accomplished by turning the screw 52, which, as before explained, passes loosely through an up-turned lip 51 of the pivoted plate 49 and I screw-threads into the end wall of the casing. When the flexible connection is in the casing, it is prevented from pulling out, as the tension it is under, due to the weight of the door, draws said roller toward the open end of the casing, causing the connection to be firmly gripped between such roller and the upper wall of the casing.

The weight of the door, hearing as it does upon the corner iron or piece 37, causes the slide 39, lying between the vertical part i of said corner iron and the edge of the door, to be forced up until its lip 42 that projects through the slot 43 in said vertical portion 1 of the corner iron comes in contact with the lower end of the adjusting screw 48. By adjusting this screw so as to force down the slide, it is evident that the door will be raised y ng the screw in the op 2.1

posite direction, the door will be allowed to move down. By this means, the door can be adjusted so as to have its edge at the required distance from the floor.

-With a door equipped with my improve 7? ments as shown and described, it will be found that the door can be moved back and forth very easily and with but little friction and little noise, and that with the flexible connection properly applied the door will be 1 maintained at all times in .absolutely perfeet position. In opening the door,that is, moving it back into its pocket,the effect will be that the pulley 24 will tend to draw down on the connection, laying it down on the track rail 57 as said pulley 24 moves along over such track rail, and by the time that the door has been fully opened or pushed back into the pocket, the pulley 23 will be quite close to the upper end of the flexible connection, and there will have been laid down on the track rail practically the same length of connection that, when the door was closed, extended at the upper part of the pocket between the pulley 23 and the fixture for the upper end of the flexible connection 22. The door, when moved back to its full extent in the pocket, will be stopped against the bumper 30, which, as stated, is provided on the turned-down end of the bracket 25.

The construction illustrated and described is one that brings the flexible connection and the pulleys around which it passes in the plane of the door, and such location of these parts results in decided advantages over any other location of such parts. For exam le, it permits the door to be moved back an forth on the single track-roller or pulley (which in the construction shown is the lower one of the two pulleys that the band passes around) with the minimum amount of tendency to tip sidewise, and it also avoids any necesslty for constructing the pocket in which an interior house door slides of any greater width than is necessary to accommodate the door itself. This latter point of advantage is deemed of great importance in practice as it not only conduces to economy of room space in such interior house constructions but also serves to prevent theformation of an unsightly space at one side of the door which would be necessary if the said sustaining devices were not located in the plane of the door.
