JAMES S. CASEY, OF VOLUNTOWN, GONNE (TICU'I.`

- y Letters .Patent No. 95,767, dated October 12, 1869.

*weg-' MROVEMENT IN STOP-MOTION POR DRAWINQFRAMES.

*WH-*- The Schedule referred to these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, J Aims S. CASEY, ot' Voluntown, in the county of Windham, and State of Connecticut, have invented a new and valuable Improvement in Governors and Stop-Motion'for Railway-Heads; and

and all breakage or other accidents to material or machinery, caused by bunches or lank places in the roving, prevented. It is 'a simple and eicient stop-motion, easily applied.

The letter A, of the drawings, represents the topf drawing-roll, the shaft of which is lengthened, and has secured to its end a small spur-wheel, a.

B and C designate eccentrics revolving about the pins b and c, respectively. These eccentries are toothed tor about three-quarters of their circumference, and so weighted vas to automatically present the lank and smooth side of each to the small spur-wheel on the end ofthe top roll.

The axis or pins b and c are fixed in the ends ofthe gelding-jaws d "d, hinged at d d to the forked support The eccentrics B and C .are diawn toward each other by the spiral spring E attached to the jaws d d, by the screw-bo1ts andnuts e e, and their distance apart regulated by means of the set-screws f f iu the forked ends of support D.

The support D isadjusted, so that the eccentrics shall gear with'the spur-wheel a', by means oi' its slotted arm D', in connectionr with the sliding standard G, working in its slotted support F, the whole being arranged so vas to bring the cecentrics B and 0 to any desired position..

The support D is provided'with a fork, H, pivoted at h, whose fingers, adjustable in slotted supports by means of the set-screws h' 71', engage with the pins b and c', xed at suitable points in the faces of the eccentrics Bv and G. y

Fixed in the opposite end of the fork H is a small prismatic rod, c', which engages in a small notch in the rod I.

The upper end of the rod I is'formed into a handle or knob. Its lower end`is keyed o n the horizontal rod K.

This rod or shaft K turns in its bearings k k", and has a spiral spring, k, coiled around it, onefend of which is fixed to it by the clamp l, the other end being firmly xed to the bearing k.

The end of the -rod K, which extends vbeyond the bearing It', has two notches or depressions, one extending beyond'r the other in sucha manneras to release the catch of the shipper whenthe rod K is turned by the action ofthe spiral spring 7c.

The yielding or up-and-down motion ofthe toproll is placed under perfect command by meansof the weights m m and coiled springs s s, producing the necessary tension for properly condensing the roving.

The operation of my invention is'as follows :v

'lhe evener being setto produc'e the required size or number of roving', the eccentiics B and C of my stop-motion are also set, to bring thelank and smooth portions of their circumference within a thirty-second part of an inch of the spur-wheel a on the end of the is ready for operation.

Now, should the roving break-or run down fine from the cards giving out, or other causes, making it impossible for the evener to keep up the number of rovtop-roll, which plavs between them, and the stop-motion ing, the small spur-wheel a'will drop, and engage with the lower ecceuimicO, whose pin c' will ,engage with the lower tine of the fork H, raising it, and thereby depressing the small catch t out of the notch in the upper part ofthe vrod I.

The rod I being released, the sha. K, operated by 'the spiral spring It, turns one-quarter` round, thereby operating the belt-shipper to stop the machine.

v In case-bunches run through, or the rolls wind-up,

the small spur-wheel a'is forced to rise, and engage with the upper eccentric B, whose pin b raises the upper tine of the balanced fork H, and the belt-shipper is caused to throw off in the same manner as before de- It will be perceived that my stop-motion is not liable to much wear, as it is still, except when called. on to perform its duty.

What I claim as my invention, and desire to secure 1. In combination with the eccentrics B and C, or their equivalents, the spurwheel af, secured to the extended shaft ofthe top roll A, substantially as shown and described.

2. The eccentrics B and C, partially toothedand weighted, so as to present their smooth and lank sides automatically to the geared end of the top roll, substantially as specied. I

.i 3. In combination with the eccentrics B and C, the fork H, constructed and arranged to operate substantially as specified.

4. The stop-motion herein described, having sliding I standard G, adjustable support D, with hinged and adjustable jaws d d, eccentrics B O, balanced fork H, spur-wheel a', shaft K, and spiral spring It, al1 constr ucted and arranged to operate with the belt-shifter,

.substantially as specified.

In testimony that I claim the above, I have hereunto subcribed my name, in the presence of two witnesses. v Witnesses: J S. CASEY.
