MULE STOP-MOTION.
Specification of Letters Patent.
Patented May S, 1917.
Application filed May 28, 1915. Serial No. 30,974.
To all whom it may concern:
Be it known that I, ARTHUR R. LAYMAN, a citizen of the United States, residing at Dover, in the county of Strafford and State of New Hampshire, have invented certain new and useful Improvements in Mule Stop- Motions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to improvements in mule stop motion.
The object of the present invention is to improve the construction of mule stop motion more especially that shown and described in an application filed by me August 26th, 1913, Serial #786,912 and to provide a simple, practical, and comparatively inexpensive construction adapted to eliminate the mechanism for operating a draft clutch for connecting the draft scroll with the shaft on which it is mounted and capable of enabling the shipper lever to be instantly operated when either the upper or lower flight or stretch of the draft rope breaks or slackens whereby the driving belt will be thrown from the driving pulley to the loose pulley and the machine stopped.
With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing Figure l is a perspective view of a stop motion constructed in accordance with this invention, and shown applied to a portion of a spinning mule, 1
Fig. 2 is a detail sectional view illustrating the arrangement of the cam arm for tripping the device for actuating the shipper lever Fig. 3 is a detail sectional view on the line 3-3 of Fig. 2.
Like numerals of reference designate corresponding parts in the several figures of the drawing.
In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a front transverse rock shaft journaled in suitable bearings 2 and provided at one end with a segment 3 or segmental arm having a grooved periphery and secured to one end of a chain 1; or other suitable flexible connection. The chain extends under a guide roller 5 and around a vertically disposed guide roller or wheel 6 and is connected at its rear end to the lower end of an upright shipper lever 7. The shipper lever 7 which is pivoted at a point intermediate of its ends at 8 on the frame 9 of a spinning mule is provided at its upper end with a loop 10 adapted to receive a belt, not shown, and capable of shift ing the same from a driving pulley 11 to a loose pulley 12.
The driving belt, not shown, is designed to be arranged in the usual manner and is shiftable from the driving pulley 11 to the loose pulley 12 to start and stop the machine. The horizontal and vertical guide rollers or wheels 5 and 6 are mounted in suitable brackets and the front transverse rock shaft 1 has disposed on it a coiled spring 1a secured at one end 13 to the floor or other fixed point and connected at its other end by a set collar 15 with the shaft 1 and adapted to be placed under tension when an arm 16 of the shaft is swung rearwardly to the position illustrated in Fig. 1 of the drawing. The arm 16 is maintained in this position while the machine is in operation by a latch 17 and is adapted to be released to permit the spring 14: to swing the arm 3 forward and actu'ates the shipper lever to stop the machine. The latch 17 which is mounted on a horizontal pivot 18 of a stand 19 is approximately L- shaped and one arm extends upwardly and is provided with a hook 20 which engages over the upper end of the arm 16 as clearly shown in Fig. 2 of the drawing. The other arm 21 extends rearwardly and is provided with lateral projections 22 and 23 adapted to be engaged by arms or levers 25 and 26 for oscillating the latch to trip the mechanism for actuating the shipper lever. The lever 25 which is pivotally mountedon the horizontal pin or pivot 18 extends rearwardly from the latter and is located above the lateral projection 22' and it is provided at its rear end with a laterally extending pivot 27 on which is mounted a pulley 28 arranged on the lower flight or stretch 29 of a draft rope 30. The lever 25 is connected at a point intermediate of its ends with a contractile spring 31 and the latter is placed ranged on the said lower flight or stretch 29 of the draft rope whereby when the draft rope brakes or slackens at the lower flight or stretch 29 the spring 31 will actuate the lever 25 and cause the same to withdraw the latch from engagement with the arm 16 of the front transverse rock shaft 1, to stop the machine.
The draft rope 30 passes over a draft scroll 32 and its upper flight or stretch 33 engages a pulley 34 of an arm 35 of a crank shaft 36 journaled in suitable bearings of brackets 37" and provided at one end with a crank 87 having a pin 38 operating in a slot 39 of a rod 4L0. The rod l0 extends upwardly from an arm 41 of a lower rock shaft and the crank shaft has disposed on it a coiled spring 13 secured to the shaft at one of its ends by a set collar 4L4; and connected at its other end to one of the brackets 37 and placed under tension and held normally so by the upper flight or stretch of the draft 'rope whereby when the said upper [light or stretch breaks or slackens the crank shaft will be released and its arm 35 will be swung rearwardly in the direction of the frame and its crank arm swung upwardly to partially rotate the rock shaft 42. The rock shaft 42 is provided at one end with the said arm 41 and its other end has an arm L5 which is connected by a rod 46 with the arm 26. The arm 26 is mounted on a horizontal pivot 17 and it is adapted to actuate the latch lever 17. The arm 26 is provided with a cam 48 located above the lateral projection 23 and adapted to engage the same and withdraw the latch from engagement with the arm 16 when the arm 26 is swung rearwardly. lVhile a pair of bracket arms is shown in the accompanying drawing for mounting the crank shaft, any other suitable bearing may be of course provided for the same.
The latch is normally urged forwardly by a coiled spring 49 disposed on the pivot 18 and connected at one end with the latch and at the other end with the stand or bracket 19. The spring will yieldably maintain the latch in engagement with the arm 16 until the latch is positively rel-eased or tripped.
It will be seen that the device is exceedingly simple and inexpensive in construction and that when either the upper or lower flight of the draft rope breaks or slackens the shipper lever will be instantly operated to shift the belt from the fast to the loose pulley for stopping the machine. Also it will be clear that the stop motion constitutes a safety device and is adapted to enable a workman or other person to throw the machine out of operation by simply disengaging the arm 16 from the latch and that a workman may go beneath the machine or otherwise operate on the same with perfect safety as it will be positively impossible for the machine to start While the arm 16 is dis engaged from the latch.
\Vhat is claimed is 1. The combination with means for operating a shipper lever including a shaft having an arm, a spring for automatically rotating the said shaft, a latch normally engaging the arm for holding the shaft against rotation and the said meansout of operation, and means adapted to be held normally against movement by the opposite flights of a draft rope, the last mentioned means when released being arranged to move the latch out of engagement with the said arm to permit the said shaft to rotate.
2. The combination with mechanism for automatically operating a shipper lever including a spring actuated shaft having an arm, a pivoted latch provided with means for engaging the arm to hold the shaft against rotation and the shipper lever against movement, a pair of separate levers arranged to engage the said latch to release the arm and spaced means connected with the levers and held against movement by the opposite flights of a d-raft'rope for actuating the said pair of levers to release the latch when the draft rope breaks.
