IMPROVEMENT lN'SELF-ACTING vMULES FOR SPINNING.

The Schedule referred to in these Letters Patent and makingpart of the same.

Toall persons to whom these presents may come:

.Beit known that I, JOHN OUMNOCK, of Salmon Falls, of the county of Stratford and State of New Hampshire, have invented a new and useful Mechanismhfor Operating the Gam-Shaft of a Self-acting Mule for Spinning; and I do hereby declare the same to be fully described as follows, reference beingV had to the accompanying drawing, of which- Figure l is a top view.

Figure 2, an end elevation.

Figures 3 and 4, transversesections of such mechanism. i

The sections 'are broken through the middle of the'cam-shaft, one exhibiting the machinery to the right and the other to the left of the plane of scction.

The object ofthe invention is to produce the nec-,

essary Stoppa-ges of rotary motion ofthe cam-shaft while the mule may be in operation,`and to accomplish this by what mechanics term a positive motion.

In the drawing- A denotes vthe cam-shaft, which, in this instance, is shown as without its usual cams.

There is fixed on the said shaft a bevel-gear, B,

having sundry arcs `or spaces, a. l) c d, of its periphery without teeth, the remainder of the periphery, or the intervening parts, having arcs, e f g h, ot teeth to engage with those of a beveled pinion, C, fixed on a shaft, D.

The said shaft D has its journals-supported in boxes or bearings in two standards, i k, there being a spring, Z, applied to one of the said standards to rest directly against the shaft D at that point which.

is in the bearing next to the pinion C. lhe spring serves as a cap to the bearing of the journal, and to admit of the shaft moving laterally and in a'horizontal direction in case at any time a tooth at one extremity of any one of the arcs of teeth of the wheel B should encountera tooth of the driving-pinion. Were it not for the spring, there would be a liability of breakage of' the teeth or injury to the machine taking place.

The shaft D carries another bevel-gear, E, which in turn engages with a gear, F, 'fixed upon a drivingshaft, G, that, when the mule is in operation, is to have a constant rotary motion impartedto it.

On the end of the cam-shaft A is an escape pinwheel, H, from whose 'inner side four studs or pins, mm m m, are extended:

A spring, I, formed and arranged'in manner as rcpresented, operates, with the said series of pins.

Furthermore, from the outer side of the wheel three escape-teeth, n n a, are extended, to operatey with a stud or tooth, o, extended from a lever, p.

To the said lever certain vertical-movements are to be imparted, whereby its tootlro will be brought into and out of the path or paths of revolution of the teeth a of the escape-pin wheel. When suchtooth o is in such path and at rest, it will block 'or stop the rotary motion of the shaft A, as a'tooth, n, will be carried against the tooth o of the lever, and while the two are in contact no rotary motion ot' the esoapewheel can take place. As soon, however, as the lever may have moved its tooth o out of engagement with a tooth of the escape-wheel, the spring I, by its pressure against one of the pins of the wheel, will cause the said wheel to turn a little, so as to throw a toothed section ot' the intermittent gear B into engagement with its drivingpinion, which then will put the gear B in revolution until the next space without teeth of such gear is cn' tered by such driving-pinion. On such space receiving the pinion, motion of the intermittent gear andv cam-shaft will cease, and not again take place until the next succeeding arc of teeth of-the intermittent gear is thrown into action with the teeth of the pinion. i

From the above it will be seen how, by the mechanism described, the cam-shaft may have imparted to it an intermittent rotary motion, whereby its cam may be caused to actin the order required.

I am aware of the subjects of the British patents Nos. 203 of lis-Z6,Y 2,141 of 1859, and 1,926 of 1860,

' and make no claiml thereto, or to any device, combination, or arrangement of devices described in either of shaft, to retreat from the former in a straight line., or

in a line parallel with the two teeth which come together, and returns to gear in the same line, so that the teeth are not struck at an angle to their sides, and not liable to be broken off; whereas in the English case the gear corresponding to the gear G of my ini vention retreats in the arc of a circle, andthe teeth,

in retreating from as well as in returning to gear, will p always strike each other at an angle to their sides, 1

whereby they are rendered liable soon to become broken olf. c v

Therefore, by the employment of the bevel-gears of the kind described and in the way set forth, and with the shaft D supported against a spring, l, :L new and importa-nt result follows, and I obtain not only zu dumblo but at simpler opemtngmechanism.

I olaim- JOHN OUMNOCK. The combination, with the cam-shaft A, of the initnesses termittontly-toothed bevel-gear B, the bevel-'gear C, R. 1-I. EDDY,
