CLUTCH.
SPECIFICATION forming part of Letters Patent No. 363,635, dated May 24, 1887.
Application tiled January 1T, 1887.
To @ZZ whom, it may concern:
Be it known that, I, FREDERICK JULIUs HENnIoHsEN, of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Clutches, of which the following is a specilication.
My invention relates to clutches and it consists in various features and details hereinafter fully set forth and claimed, the primary object of the invention being to overcome the jar or concussion dueto sudden engagement of the teeth of the two parts.
ln the'drawings, Figure 1 is a perspective view of my improved clutch, showing only one of the clutch-hubs; Fig. 2, a plan view with the cap-plate and clutchhub removed; Fig. 8, a section on the line x x, showing the cap-plate and clutch hub in position; Fig. 4, a similarview on the line y y,- Fig. 5, a view on the line z z, with the hub and cap removed; Fig. 6, a bottom plan view or" the eap-plate5 Fig. 7, a vertical central sectional view of the clutch-hub, and Fig. 8 'a view of the parts separated.
A indicates the clutch as a whole mounted upon and rigidly secured to a shaft, B, the device comprising a case or shell, C, a cap-plate, D, and a clutching-hub, E, the cap-plate being secured to the case or shell and serving to conine the clutching-hub to its seat.
The casing or shell C, as shown in Figs. 2, 3, 4, and 5, is provided with a central socket or depression, a, circular in cross-section, to receive a depending hub or tlangeJ), formed upon the under face of the clutching-hub E, the socket forming a bearing for the hub E in its movements. The shell or casing G is further provided with a IaterallyeXt-ending circumferential wall or liange, c, with lugs d d in the bottom on opposite sides diaxnetrically from each other, and, finally, with studs e e,
upon the face or edge of the wall or flange c, as clearly shown in Fig. 2.
The cap-plate D is merely a dat plate provided with two sets of sockets, ff', on its under side at its edge, which are adapted to t upon or to receive the studs e e, as shown in i Figs. l and 4, the sockets ff and ff being arranged diametrically opposite each other, as shown in Fig. 6. Capplate D is further provided near its outer edge with two curved Serial No. 221,661. (No model.)
slots, y g, concentric with the axis of shaft B, as shown in Figs. l and 6, with a central opening, h, and with a seat or depression, i, upon or in its under face 'around the opening h. This construct-ion forms a flange, j, which, as shown in Figs. `l and 6, is cut away for about a quarter of its circumference, as at 7c, to receive a lug, Z, formed upon the clutchinghub E.
Screws F pass through the slots g into the shell or case C, and thereby retain the cap in place upon the latter, though permitting one to be moved upon or in relation to the other without entirely removing the screws.
The clutching-hub E fits loosely upon the shaft B and is'provided upon its upper face with teeth m, and at the base of the teeth is formed a laterallyeXtendiug circular flange, n, which latter is turned to [it the'socket'i in the under face of plate D. The inner or under face of iiange n of clutchinghub E also has formed upon it two depending lugs, o o, which, as shown in Figs. 7 and 8, will preferably be formed in the shape of two nearlysernicircular flanges with their ends separated.
'W'hen the hub E and plate D are in place, the latter is kept to its scat or socket a in the shell or casing by the flange]` of the cap, the toothed portion of the hub projecting upward through the 'opening lt above the face of plate D. lt will also be noticed that the lug or arm Z upon the hub E projects into the recess k of the iange j, the space or recess k connecting with the opening 7L and forming merely a lateral extension or enlargement thereof.
G G indicate two coiled springs, secured at their outer ends to the lugs d of shell C and at their inner ends to the lugs o o upon thev under side of the hub E. Each spring makes about two complete coils, and is conveniently attached to the lugs d and 0 by merely forming hooks upon its ends, the springs thereby serving to connectthe hub E and the case or shell.
From the above-described construction it follows that as soon as the teeth m of the clutchhub engage with or are engaged by any suitable device for locking the said device and the clutch together-as, for instance, a pawl or a second toothed hub-to cause them to rotate in unison, the clutching-hub E, being free upon shaft B, may rotate a IOO a I 363,635Y
limited distance thereupon-a distance equal to the length of the recess k less that of lug Z. As the clutching-hub thus begins to rotate the force of the springs G G is overcome, and they are Wound up While the lug or arm Z on the-hub is moving the length of recess k. As the hub E moves or rotates, it moves the clutch as awhole through or by reason of the springs G G, or, in other words, the hub E yields when the power is first applied, the resistance increasing with the power up to a certain point, when the arm or lug l reaches the end of the offset k, unless the tension of the spring becomes sufficient to overcome the resistance of the case or shell against rotation, which will of course depend upon what is connected with or moved by said shell or case.
As suggested, it may in some cases happen that the springs will be strong enough to prevent the lugl from engaging with the capplate, in which case the strain would all come upon the springs; but such construction is not desirable, because of the constant ystrain upon the springs. It will also be seen that the springs may be so weak or light or the resistance offered by the driven machinery may be so great as to preclude any movement of the clutch-hub until the lug reaches the end of its movement in recess 7c, the springs in such case failing to takeup the jar incident to the sudden clutching.
To permit the adaptation of the device tov the special work contemplated, it is found desirable to provide for the adjustment of the springs, and this is accomplished by loosening the screws F F, lifting the cap plate D up so that its notches fwill be out of engagement with the lugs e, and then replacing the capplate with the lugs e in engagement with the notches j", and securing the cap-plate in place. This movement or adjustment of the cap-plate is provided for by the curved slots g g, and it will be noticed that when the springs have been thus adjusted the screws F will be in that end of the slots g g opposite to that which they occupy in Fig. l.
lt is of course to be understood that as the cap-plate is thus rotated the hub E is likewise rotated, the lug Z, when the clutch is out of operation, being in engagement with the capplate, as shown in Fig. l, and it is this rotation of the hub with the capplate that effects the adjustment or increased ltension of the spring as the springs are secured to the hub. rlhe object of making the lugs o 0 on the under face of the hub Ein the shape of projecting semicircular iianges is that they form a hub upon which the springs may wind, as shown in Figs. 3, 4, and 5. A
Inasmuch as the devices which will engage with or be engaged by the hub E will vary according to the class of machines to which the invention is to be applied, I wish it understood that I do not limit myself to the'particular form of clutching-hub shown, it being apparent that the engaging-face of said hub may be constructed in various ways without departing from the spirit or substance of my invention. Likewise I wish it understood that I do not limit myself to the exact construction and arrangement of springs shown, as it is apparent that spiral springs may be used in lieu of those shown. l
The clutch herein described and shown is particularly designed for use on that class of machines known as broadcast seeders,77 and is found in practice to give excellent results, the construction being simple and cheap and easy of operation. It is equally applicable to grain-drills, hay-rakes, fertilizer-distributers, various machines found in machineshops; in fact, wherever it is necessaryto clutch two parts, one in motion and the other at rest.
By means of the springs'which allow a yielding motion to the cluthing-hub all danger of fracture due to the sudden starting of machinery is entirely obviated.
The number of springs may be varied, as may also the number of lugs d e'o and slots g.
I claiml. In combination with a shaft, ashell or case secured thereto, a toothed or clutching hub, and intermediate springs connecting said parts, but permitting a limited movement of one relatively to the other.
2. In combination with a shaft, a shell or case rigidly secured thereto, a clutchinghub loosely mounted upon the shaft, and a spring connected at its ends with the shell or case and the hub. l
3. In combination with a shaft, a shell or case secured thereto. a clutching-hub-loosely mounted upon the shaft and adapted to move a limited distance independently of the shell or case, and a spring connecting the hub and the case or shell.
