Application fi1ed:March 19, 182%; Serial No. 70.938 9 To all. whom it; may concern:

Be itknownthat LCARL G. Knunonn, a; citizen of. the United States, residing at San Antonio in the county of Bexar; and};

State of Texas have invented certaininew and useful l mprovements inAutomatic Cotton Packers of.- which the following is a specification, reference beingv had to the ac companying drawings.

This invention relates. to automatic cotton packers of the character disclos'edin the patent. granted to Georgel/V. Cameron, Patent #nisasei, June, 1916.

One of the objects of; the present, invention is to provide means for automatically braking the feeder. which feeds the cotton. into the packing box and. beneath the plunger or ram..

A further object is to provide means for automatically shifting the belt which operates this. feeding mechanism sothat when the brake is applied to the pulley which drives this feedingmechanism the;belt will I the brake is removed thebelt will be shifted into operative engagement with the pulley.

A further object is to provide a construction of this character in which the braking,

action is automatic. and controlled by the plunger or ram of the packer whereby said belt shifting anda'utomatic brakingyaction is 'caused to occur intermittently.

A further object is to provide a construc.- tion of this character which is very simple, may be readily applied and will not be liable to get out of order.

Other objects will appear in the course of the following description.

My invention is illustrated in the panying drawings wherein:.

Referring to these drawings, A and. B.

designate the] longitudinal beams of longi tudinah supporting. sills ofa cotton packer these sills being parallel to each other but spaced from each other by's uitable tnanS I verse braces. These sills. are; supported; by. vertica members C d] D and; moun ed? 1 .0 1. the r a cm. 18. D is the. feeding hopper, E of the. cotton packer. This hope per feeds into the-- packer? box; F of. the packerinany, ordinary-10rusual manner and; at this end there"; is a. feeding roll 10 dis.- posed; within the hopper which extends out through hopper, one end of, the shaftcarryingupon it. the sprocket wheel;l1..; Mounted upon an.

upright Gr forming part of the frameofth'e;

machine is a drive shaft. 12 carrying: a sprocket wheel, 1.3 and. over this sprocket E, the} shale. of. the ends; of the wheel passes a sprocket chain 14.; WlllGlIfBX-j' tends arounch the sprocket wheel; 11, thus thesprocket wheel 11, and thefeeding roller are driven. fromathe shaft 1 2. Mounted up:

on the shaft 12' is a fast pulley 15 and.

disposed. also. upon this shaft and. imme-i diately adjacent the pulley 15 is a loose pulley l6. Passing; either over thepulley 15. of. the loose pulley 16 is a belt. 17 which extends downward; from a power shaft mounted in'an'y, suitable manner, this. shaft" I not beingshown'. I Mounted in. bearings 18, on the. under faces of the longitudinal beams A and-JB. is. a

which is pivoted the-link 211" This. link at its opposite end. extends into aiposition contiguous to the vertically inovable' plunger and plunger. guide of the tramper-"an'dis pivoted to aflever'22. which eXteiids dow-n pivotally connected, as at 23, tothefplate 24.. The-link 21 at-its end. which is "pivoted to the lever 22 is formed, toiprolvide a stir the up-wardly ward and away from the link 21 and is rup,.-bend-.- 25. and in this. stirrup-a roller 26 is supported, this roller being disposed in such position as to be engaged by a vertically movable finger 27 bolted to the footof the guide post 28 which guides the plunger-or ram. On the upward movement of the plunger the beveled end of the finger 27 is forced against the roller 26 causing an-upward and inward movement of the roller and of the rod 21, thus causing an oscillation of the rock shaft 19 in one direction.

Attached to the upper extremity of the arm 20 is a contractile spring 29 which tends to pull this arm 20 over toward the left in Figure 5. The extremity of the rock shaft 19 remote from the contractile spring 29 is angularly bent, as at 30, so that'this angular arm so formed extends upward and outward. Operatively connected to the extremity of this angular arm is a longitudinally shiftable rod 31, whose end remote from the ex tremity of the arm'20 is shiftably mounted in a bracket 32 mounted upon the adjacent post cillated inone direction or the other the rod 31 will be longitudinally shifted in one directionor the other. This rod 31 carries upon it'the two upwardly extending spacedv belt shifting fingers 33 which engage the belt 17. When the rod'3l is shifted in one direction the belt will be shifted onto the loose pulley and when shifted in a reverse direction the belt will be carried onto the fixed pulley.

Mounted in bearings upon the'upper faces of the sills A and B is a transverse rock shaft 34: which carries intermediate its ends the downwardly extending arm 35 which is shaft 34: will be oscillated.- This rock shaft carries upon it and operatively connected to it the brake shoe 38 which is adapted to be applied to the fixed pulley 15. In other words, when the rock shaft 34 is oscillated in one direction the brake will be applied to the fixed pulley and when it is oscillated in the other direction the brake will be relieved from the fixed pulley. The lower extremity of the arm 35 has attached thereto one end of a contractile spring 39, the other end of which is attached to any suitable point of support as, for instance, one of the transverse beams, and this spring acts to urge the rock shaft into a direction which will carry the brake shoe against the face of the pulley.

The operation of this invention is as fol lows: lVhile thecotton is being fed into the press box before the plunger is lowered, the belt 17 is engaged with the fast pulley 15. Under these. circumstances, of course, the plunger is raised as well as the plunger guide and as a consequence the beveled end C. Thus as the rock shaft 19 is osof the finger 27 has borne against the roller 26 and forced the link 21 over toward the right. This carries the arm 30 over toward the right but shifts the rod 31 so that the fingers 33 carry the belt inengagement with the fixed pulley 15, thus driving the feeding mechanism through the shaft 12 and the sprocket chain 14. As soon as the plunger moves downward, however, andthe finger 27 has released the roller 26, the springs 29 and 39 act to oscillate the shaft 19 to the left and shaft 34 to the right. This movement of the shaft 19 acts to shift the rod 31 so as to carry the fingers toward the left in Figure 1 and shift the belt:17 from the tight to the loose pulley and at the same time the oscillation of the shaft 34 applies the brake shoe to the fast pulley, stopping-the feed ing mechanism immediately so that no cotton is fed from the hopper into the press box while the plunger is descending. The parts will remain in this position until the plunger again ascends, whereupon the beveled end of the finger 27 engages the roller 26, shifts the arm 21 to the right and again applies the belt to the fast pulley and releases the. brake and thus causes the driving of the feeding mechanism. It will be seen that this shifting of the belt and of the brake is automatic in its action and is entirely produced by the intermittent up and down movement of the packing plunger. Thus the belt shifting and braking action is entirely under control of the plunger or ram of the packer and occurs intermittently whenever the packing plunger rises or lowers. WVhile I have illus trated certain details of construction and arrangement of parts which are particularly designed for use with the Cameron packer, forming the subject-matter of Patent #1,188,894, I do not wish to be limited thereto as it is obvious that many changes .might be made in these details of construction and the arrangement of parts in order to fit the mechanism to other cotton packers without departing from the spirit of the invention as set forth in the appended claims.
