WILLIAM P. BARKER, OF ORANGE, MASSACHUSETTS.
SEWING-MACHINE CLUTCH.
SPECIFICATION forming part of Letters Patent No.
241,180, dated May 10, 1881,
Application filed March 7, 1881. (No model.)
To all whom it may concern:
Be itknown that I, WM. P. BARKER, a citizen of the United States, residing at Orange, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Sewing-Machine Clutches and I do hereby declare that the following is a full, clear, and exact description ot'the same, reference being had to the accompanying drawin gs, making a part of this speoificatioinletters of reference being the same for the same parts in different views.
Figure 1 shows a vertical cross-section of the entire device as applied to the driven shaft of a sewing-machine. Fig. 2 shows the inner side of hand-wheel; Fig. 3, the side of driven pulley, having upon its side the radial ratchet. Fig.4 shows the clutch-pin drawn out.
My invention relates to that class of devices designed to prevent the accidental backward motion of a sewing-machine, and also to permit of winding bobbins without running machine.
I have observed that devices for this purpose as at present employed are faulty, from the fact that in some cases the hand-wheel being loose upon the shaft, the operator has no means of moving the machine backward for a part of a revolution, as is sometimes very desirable. In other cases a special movement is necessary to detach the clutch -pulley, thus losing the advantage of an automatic clutch.
To obviate these objections I have constructed a device which consists of a hand-wheel rigidly attached to the shaft at all times, and a belt (or driving) pulley is so connected that its forward motion will be imparted to the handwheel and shaft, while if accidentally started backward it will move freely upon the shaft without moving machine.
In describing my invention, I refer to the drawings making a part of this specification.
In Fig. 1 A is the shaft and B a hand-wheel permanentlyattachedtothesame. This hand- Wheel has bored into its convex side a cylindrical aperture just large enough to admit freely the enlarged end of pin D. The smaller part of said pin passes through the hand-wheel and terminates in the knob F. At the back of said knob is a small projection, E, which, when the clutch is in use, fits into the hole shown at c, Fig. 4, in which position the pin I) projects beyond the face of hand-wheel and engages with the radial ratchet-teeth a a a a, against which it is held by the spring d, thus causing the forward motion of belt-pulley c to be communicated to hand-wheel; but should the beltpulley he accidentally started backward, the spring d will admit of the pin D passing over the inclined teeth a a a a, thus preventing the hand-wheel from receiving any part of such backward motion; and should it be desirable for the purpose of winding bobbins to entirely disengage the two parts, the knob F may be drawn back until the pin E shall come outside the surface of hand-wheel hub, when a partial revolution of the said knob will cause the pin E to rest upon the surface of the wheel, thus preventing the contact of pin 1) with the ratchet.
I am aware that devices for this purpose have been made having a loosely-revolving wheel; but
What I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with the driven shaft of 7 5 a sewing-maching having permanently affixed thereto a solid hand-wheel, of a separate and distinct belt-pulley, so arranged as to revolve loosely upon the said shaft in one direction, and to become automatically engaged with the said hand-wheel when revolved in the opposite direction, substantially as shown and described.
2. The combi nation of shaft A, wheel B, pulley (J, having the inclined radial teeth a a cut, pin 1), and spring d, all arranged substantially as shown.
3. The spring-bolt D, in combination with the knob F, having the projection E, as and for the purpose described.
