3 Claims.
My invention relates to the field of sewing machines, and more particularly to a desk or table having a sewing machine rotatably mounted thereon in such a manner that the machine can be placed in the concealed position or in a usable position without moving other portions of the table or desk structure into a supporting position.
In the conventional mounting of a sewing machine on a desk or table, the machine is rotatably supported on one of its longitudinal sides from a fixed portion of the structure, with the machine when not in use being rotated downwardly into a rectangular opening formed in the horizontal top portion of the desk or table. Upon it being desired to place the machine in a usable position, the machine is rotated upwardly on one of its longitudinal sides to a position where a second hinged member can be rotated under it to form a shelf for supporting one of the sides ofthe base of the machine, with the opposite side of the machine being supported on the hinges affiXed to the base of the machine.
It is to eliminate the inconvenience of using the presently available mounting for a sewing machine which requires several operations to place the machine in or remove it from the usable position that I have devised my present invention.
A major object of my invention is to provide a mounting for a sewing machine which is adapted to rigidly maintain the machine in an operating position on a desk or table, but permitting the machine to be rotated lengthwise into a concealed or operating position.
Another object of my invention is to furnish a sewing machine mounting having an extremely simple mechanical structure, that can be operated with a minimum of effort, can be manufactured from standard commercially available material, and hence retailed at a price which will permit the use of my invention in movably supporting sewing machines installed in existing tables and desks as well as in new furniture in which a sewing machine is incorporated.
These and other objects and advantages of my invention will become apparent from the following description of a preferred form thereof, and from the drawing illustrating that form in which:
Fig. 1 is a side elevationalview of a desk having a sewing machine rotatably supported thereon by the use of my mounting, with the location of the machine in a concealed non-operative position being indicated by phantom line;
Fig. 2 is a vertical cross-sectional view of the machine in a concealed position taken on the line 2-2 of Fig. 1;
\ members 2 l Fig. '3 is a vertical longitudinal cross-sectional view of the mounting taken on the line 33 of Fig. 2, with the sewing machine being in the concealed position; and,
Fig. 4 is a vertical cross-sectional view of the bolt mechanism for holding the machine in an operating position taken on the line i t of Fig.- 3.-
Reierring now to Fig. 1 for the general arrangement of my invention it will be seen that a conventional power operated sewing machine M is supported in a rotatable position ona shaft mechanism S from the upper portion of a desk D, with the machine being held in an upright operating position by a slidably movable bolt B.
The supporting desk D is of a conventional design, and is formed with a substantially horizontal top it that has a rectangular longitudinally extending opening l'l formed therein asoan best be seen in Fig. 2. A rectangular sewing machine base l2 that serves as a support for the sewing machine driving mechanism l3 and the needle bar holding head M is rotatably supported b the shaft mechanism S whereby the machine M can be rotated length-wise in the opening ll to place the machine in either an operating or concealed position. It will be noted in Fig. 2 that the base i 2 is of such width as to bridge the op m ing' 'i 6', but is not of sufiicient length to completely occupy the opening I l as-can best be seen in Fig. 3.
,, porting the machine M from the shaft mecha-' nism S it will be apparent that an elongation of the ribs l5 'mus't be provided at each end'there'of in order that the base portion of the machine M will substantially fill the opening H. The path of the upper portion of the driving mechanism [3 and the head !4 asth'e machine M is rotated is shown by the phantom'line E8 in Fig. 1.
In Fig. 3 it will be seen that the elongation of the ribs i5 is accomplished by welding or other wise securing a flange 26' to each end thereof whereby the resulting flanges extend substantially the entire length of the opening I l. A rectangular wooden member 2 is provided for each end of the machine base [2, with each of the members extending to the ends of the flanges 20 which it is supported between. Thus, upon the sewing machine M being disposed in the upright position shown in Fig. 1, the opening I! is substantially closed by the base l2 together with the To provide for the opening H being closed when the machine M is in the inoperative position shown by phantom line in Fig. 1 a rectangular member 22 is affixed to and extends the entire length of the ribs 55 and flanges 20, with the member 22 being positioned on the sides of the ribs and flanges opposite the base I2 as can best be seen in Fig. 3. The member 22 is preferably formed from the same material as the top H) of the desk or table whereby it will blend therewith when the machine is in the inoperative position.
Each of the ribs I5 is formed with a centrally disposed horizontal bore 23 therein through which is inserted a bushing 24 formed from a soft material such as brass. A substantially horizontal bolt 25 extends through the bushings 24, with each end of the bolt being supported by an inverted L-shaped bracket 26 that is mounted by screws 26a on the under side of the top l adjacent the exterior face of one of the ribs I5. Situated on the bolt 25 between the exterior face of each of the ribs l and the interior face of one of the members 26 is an annular spacing ring 21 that prevents lateral displacement of the base l2 in the opening ll. Upon it being desired to demount the machine M the nut 28 on the bolt is removed, and the bolt displaced from the members 26 and ribs l5.
The sewing machine M is maintained in the desired position by the use of the bolt mechanism S. In Fig. 4 it will be seen that the bolt B is l formed from a horizontally disposed rod 30 having a conventional downwardly extending handle affixed thereto, with the bolt being slidably supported by two laterally spaced U-shaped members 3l' which are affixed to the underside of the desk top ID. The inner portion of the rod 30 is adapted to engage a bore 33 formed in one of the ribs l5 whereby when the rod is so positioned the sewing machine M is held in an upright operative position. The bolt 30 is also adapted to engage a bore 34 formed in the opposite end of one of the ribs IE to lock the machine M in the inoperative position shown by phantom line in Fig. 1.
It will be apparent that due to the rotation of the sewing machine M in moving from the operative to the inoperative position that the end of the opening H is preferably beveled slightly vertically to permit such movement, with a crack of minimum width being visible between the end 42 of opening II and the ends of members 2i and 22.
The operation of my invention is extremely simple. With the sewing machinein the operative position shown in Fig. l, and it being desired to place the machine in the inoperative concealed position, the bolt 30 is moved outwardly by a downwardly extending handle extending therefrom to permit the machine M to be rotated in a counterclockwise direction on the bolt 25 until the machine M is in the position shown in Fig. 4. It will be apparent that during this operation the sewing machine M must be held by the hands to prevent a violent downward swing of the machine which could do irreparable damage thereto.
With the sewing machine M in the inoperative position the bolt 30 is moved forwardly whereby the inner end thereof engages the bore 34, and the machine is locked in the inoperative position. Of course, prior to the sewing machine M being rotated downwardly from its normal operative position the insulated flexible conductor which carries electrical power to the machine M is disconnected therefrom, and reconnected when the machine is returned to the operative position.
To place the machine M in the operative position the above described operation is simply reversed, and the bolt 30 caused to engage the bore 33 to hold the machine in the upper position as shown in Fig. 1.
While the above device herein described is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred form of my invention, and that I do not mean to limit myself to the details of construction hereinshown and described other than as defined in the appended claims.
