EARNEST LEONARD JACKSON, OF COLUMBUS, GEORGIA, ASSIG'NOR 0F SIX-TENTHS TO RICHARD C. DEIGNAN, OF COLUMBUS, GEORGIA.

STOP MECHANISM FOR SPINNING-FRAMES, SPEEDERS, AND THE LIKE.

Application filed October 28, 1912.

To all whom it may concern Be it known that I, EARNEST L. JACKSON, a citizen of the United States, residing at Columbus, in the county of Muskogee and State of Georgia, have invented certain new and useful Improvements in Stop Mechanisms for Spinning-Frames, Speeders, and the like; and I do hereby declare the following to be a full, clear, and exact descriptiorf of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stop mechanisms for spinning frames, Speeders, and the like, and has for an object to provide a device adapted to actuate the usual and ordinary stopping mechanism on a speeder when the cone belt breaks.

A further object of the invention is to provide mechanism which in addition to stopping the speeder when the cone belt breaks also serves to actuate the stopping mechanism when the traverse runs too high or too low.

A further object of the invention is to provide mechanism which will actuate the stopping device of a spinning frame when the traverse runs too high or too low.

A further object of the invention is to provide a mechanism having a rack and pinion such rack being connected with the traverse and moving therewith and with a trigger serving to hold a weight suspended,which when dropped will serve to actuate the stopping mechanisms of the speeder or spinning frame.

With these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated .in the accompanying drawings, and pointed out in the claims hereunto appended. I j

In the drawings: Figure 1 is a view in side elevation of the improved stopping mechanism applied to a speeder. Fig. 2 is a view in side elevation of the device at tached to a spinning frame. Fig. 3 is an enlarged view'in side elevation of the device seen from the side indicated at Fig. 1. Fig. 4 is a view of the device in side elevation from the side opposite that seen at Figs. 1 and 2. Fig. 5 is a view in edge elevation from the edge indicated by the arrow 5 at Figs. 1 to 4 inclusive. Fig. 6 is a transverse Specification of Letters Patent.

. The improved ,stoppingmechanism which forms the subject matterv of this. application cone 22 of a speeder or beneath the traverse 23 of a spinning frame. Upon the frame 20 a sliding frame 24 is mounted, the said frame carrying an arm 25 connected by means of a link 26 and bell crank lever 27 and through the medium of a rod 28 with the usual and ordinary latch 29, as shown in" Fig. 1 and employed upon speeders or to the belt shifting device indicated at 30 upon the spinning frame shown at Fig. 2. It will be therefore, apparent that when the sliding frame 24 drops, it will, through the medium of the mechanism just enumerated, actuate the latch of a speeder or the belt shifting device of the spinning frame to stop the machine in the usual well-known manner.

To insure the dropping of the sliding frame 24 when the cone belt 31 breaks, the cone drop 32 is provided with a rod 33, and the sliding frame 24 is connected with such drop through the medium of a rod 34 slidably connected with the sliding frame by means of a reduced neck 35 and head 36 and clip 37, as indicated more particularly at Fig. 11. When, therefore, the cone belt 31 breaks and the lower cone drops, the rod 34 actuates the sliding frame 24 and through the medium of the bell crank lever 27 and the connecting means, the stopping mechanism of the machine is actuated.

For actuating the stopping mechanism by the traverse of the speeder, or when the spinning frame runs beyond its limit, a rack 38 is slidably mounted upon the frame and engages with a pinion 39 rigidly mounted upon a shaft 40, which shaft also carries a crank disk 41. The crank disk carries a wrist pin 42 positioned to engage in a notch 43 in the upstanding arm 44 of the latch member 45, shown in perspective at Fig. 14. The rack 38 is also provided with a pintle 46, positioned to engage under the end of the latch member 45 opposite the arm 44.

From the foregoing it will be apparent that when the wrist pin 42 engages the notch 43 in the latch 45, it serves to depress the same and when the pintle 46 engagesthe opposite end of such latch it serves to raise such opposite end and to have the same ef fect upon the latch as being" depressed by the wrist pin 42. It will, therefore, be apparent that' whether the rack 38 runs too high or too low, the latch 45 will be similarly actuated. The latch 45 is provided with a detent 47 which serves to engage the lever 48 and to hold such lever 48 against the tension of the spring 49, the spring 50 tending to hold the latch 45 against depression by the wrist pin 42 or the pintle 46. The lever 48 is pivoted at 51 upon the stud carrying the spring 49, and is actuated by means of a lever 52 pivoted to the frame as at 53 and provided with a cam extremity 54 against which acts a roller 55 carried by an arm 56 formed upon or moving with the link 26, so that when the frame 24 drops carrying with it the link 26, the roller 55 acting" against the cam surface 54 servesto throw the lever 52 in a direction indicated by the arrowin Fig. 7 and to throw therewith, through the mediumof the link 57, the lever 48. The lever 48 bears against the lower end of the trigger 58 pivoted at 59 to the frame 20 and held, normally yieldingly against the action of the lever 48, by means of a spring 60.

Slidable upon the frame 20 is a weighted drop 61 having a notch 62 positioned to be engaged by the trigger 58, when held in position by the lever 48 and to hold such weighted drop in elevated position. The weighted drop is provided with a slot 63 embracing the arm 25 and is provided with a pin 64 positioned to impinge against such arm when the weighted drop falls, so that when the trigger 58 is released from the notch 62,, the weighted drop falls and the pin 64 impinges against the arm 25 by reason of the weight of such weighted drop 61 serving to move the frame 24 downwardly and to actuate the bell crank lever 27 and rod 28 as described in relation to the drop of the cone, such drop of the frame 24 being permitted by the elongated reduced shaft 33 of the link 34 connecting the same to the cone drop. It will be apparent,therefore, that as the traverse runs too high or too low moving the rack 38 therewith, the shaft 40 will be rotated to actuate the latch 45 either through the medium of the wrist pin 42 or the pintle 46,, whereby the detent 47 is depressed out of engagement with the lever 48 which permits the spring 49 to throw such lever and also permits the spring to throw the trigger 58 out of engagement with the notch 62. This permits the weight of the drop 61 to fall to actuate the sliding frame 24 and bell crank lever 27 as described. It will be apparent therefore, that as the traverse either of the spinning frame or the speeder runs above or below its normal limit, the stopping mechanism of the machine will be actuated. It will also be apparent that as the sliding frame 24 drops it will through the medium of the lever 52 return the parts to engaging position, so that when the weighted drop 61 is again raised, it will be automatically engaged by the trigger 58 to hold it in normal position. To raise the weighted drop 61 the said drop is provided with an offset 65 having a recess 66 proportioned to receive the extremity of the bell crank lever 67 pivoted at 68 to the frame 20 and controlled through the 1116- di'umof a rod 69 with a lever 70 pivoted in the creel 71 of the speeder or the lever 7 O pivoted to the frame of the spinning frame. In the speeder the lever 70 is connected with the sliding rod 72 which is manually oper- 9 ated to start the machine after being automatically stopped. It will be understood that the rod 72 runs the entire length of the speeder and is controlled from any point at which the operator-may be. This rod 72 is found upon all speeders and the lever 70 is simply connected therewith in any usual well-known manner. It will be apparent therefore, that when the trouble has been adjusted and the rod 72 manually moved to start the machine, the moving of such rod 72' automatically raises the weighted drop 61 and sets the machine in position for use.

To connect the traverse 73 of the speeder with the rack 38 an arm 74 is rigidly connected therewith, as shown at Fig. 1,. and is connected with the rack in any approved manner as indicated at Fig. 3. To connect the rack with the traverse of the spinning frame a rod 76 is connected with the traverse 23 and any approved coupling as 77 is employed to connect with the upper extending rod 78, which forms a continuation. of the rack 38.
