STOP-MOTION FOR MULES.

SPECIFICATION forming part of Letters Patent No. 553,195, dated January 14, 1896.

Application filed October 30, 1895. Serial No. 567,363. (No model.)

' To all whom it may concern:

Be it known that I, FREDERICK LUsSIER, a citizen of the Dominion of Canada, residing at River Point, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Stop-Motions for Mules; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in devices for releasing the well-known stopping mechanism.

The object of the invention is to automatically release the stopping mechanism when portions of spindle-bands or waste of any character becomes wound around the driving-belt sufficiently to increase the diameter thereof.

The invention consists in the combination with the connecting-rod of the stop-motion and the hand-lever by which the same may be operated, of a detector-finger adjacent to the belt and connections intermediate the detector-finger and the hand-lever to throw the same to a position where the connecting-rod may be operated by its spring when the detector-finger is thrown by the contact therewith of a bunch on the driving-belt.

The invention also consists in such other novel features of construction and combination of parts as are hereinafter more fully described, and pointed out in the claims.

Figure 1 represents portions of the muleframe with the driving-belt, the hand-lever, and the connecting-rod shown in combination with the detector and the connections between the same and the lever. Fig. 2 represents an enlarged view of the detector and its connections removed from the machine, part of the driving rope or belt being shown in position.

Similar numbers of reference designate corresponding parts throughout the views.

In carrying my invention into practice it has been my object to prevent the carrying of waste (from broken spindle-bands or from any other source) by the driving-rope into positions whence it may be conveyed between gears or into contact with parts of the moving mechanism to the detriment thereof. My purpose has also been to accomplish this object ning in its normal condition.

by the aid of simple and inexpensive mechanism which could be connected with the present stop-motion.

In the drawings, 5 represents the machine frame of the usual construction and furnished with the ordinary belt-pulleys 6, 7 and 8, carrying the driving belt or rope 9. Pivoted on the frame is the usual crank hand-lever 10, the short arm 11 of which is pivotally connected with the well-known stop-motion rod 12, ordinarily operated by a spring when the lever 10 is released. In my improved mechanism the short arm 11 of the lever is provided with the pin 13. The rod 14 is journaled parallel to the axis of the pivot on which the lever 10 swings. On this rod are mounted the finger 15, bearing on the pin 13 of the lever 10, and the clamping-block 16, having two perforations, each provided with a clampingscrew 17 and 18, working through a socket at right angles to the perforation. By the screw 17 this block 16 is secured to the rod 14:, while by means of the screw 18 the shank 19, carrying the detector 20, is adjustably secured in the block. The detector has the lateral arm 21 curved atits end and the vertical arm 22 also curved at its end, to provide for the free entrance between the arms of the driving belt or rope 9.

The shank 19 is adjusted in the block 16, so that the belt 9 just clears the arm 21 when run- Should waste or foreign material of any nature become engaged with the belt 9, it will ultimately be brought against the arm 21 of the detector, and meeting with resistance to its passage will have a tendency to drag the detector along in the direction of the arrows a ain the drawings, causing the rotation of the rod 1 1 by the detector and the throwing of the lever 10 by the pressure of the finger 15 on the pin 13, thus allowing the heretofore well-known stop-m0- tion mechanism to act in the same manner as when the lever 10 is thrown by hand.

Having thus described my invention, I claim as new and desire to, secure by Letters Patent- 1. In a stop-motion of the nature described, the combination with the usual hand-lever, and the stop-mechanism releasable thereby, of the driving-belt, a detector adjacent thereto adapted to be actuated by any material increase in the diameter thereof, and a swinging connection between the detector and the hand-lever.

2. The combination With the frame 5, the lever 10 pivotally mounted thereon and having the arm 11 provided With the pin 13, and the connecting-rod 12 pivoted to the arm 11 and being the usual connection between the hand-lever of a mule and its stopping-mechanism, of the rod 11 mounted in bearings, the finger 15 adjustably clamped to the rod and bearing on the pin 13 of the lever, the perforated block 16 adj ustably clamped to the rod 1-1 by the screw 17 and the shank 19 carrying the detector 20 consisting of the arms 21 and 22 adj ustably clamped in the vertical perforation of the block 16, as described.

In witness whereof I have hereunto set my hand.
