EMMET H. MCMURRY, OF MARIANNA, ARKANSAS, ASSIGNOR OF ONE-FOURTH TO JAMES L. WEST, ONE-SIXTH TO HAL S. MIXON, ONE-SIXTH TO ROBERT L. MIXON, AND ONE-SIXTH TO LARIMORE ROBINSON, ALL OF MARIANNA, ARKANSAS.

BILLING-PRESS.

.T 0 all whom it may concern:

Be it known that I, EMMET H. MeMURRY, a citizen of the United States, residing at Marianna, in the county of Lee and State of Arkansas, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to baling presses and is more particularly an improvement upon the apparatus described and claimed in Patent No. 855,015, granted to me on May 28, 1907.

The invention resides especially in improved power mechanism whereby the rotation of a driving element will be caused to operate mechanism to produce a preliminary compression of the hay or other material supplied to the press and cause said material to be directed into the path of the main plunger or follower which subsequently completes the compression of the material within the pressure box.

Another object is to simplify the construction of power mechanism for producing the above result and to provide such mechanism which can be conveniently operated, will not easily get out of order and which can be readily repaired in the event of the breaking of any of the parts.

With these and. other objects in view the invention consists of certain novel features of construction and combinations of parts Which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a plan view of the mechanism embodying the present improvements, the press being shown in connection therewith, and portions thereof being in section. Fig. 2 is a longitudinal section through the apparatus. Fig. 3 is a central transverse section through the press. Fig. 4 Fig. 5 is a plan View of the power transmitting devices of the preliminary compressing mechanism. Fig. 6 is a transverse section through the guide trough of said mechanism, and showing the deflecting blocks in end elevation. Fig. 7 is a detail-view of a portion of one of the deflecting blocks and the clutch members cooperating therewith. Fig. 8 is a transverse section through a portion of the trough and showing the guides of the main plunger.

Serial No. 379,065.

Fig. 9 is a view partly in section and partly in elevation of the connection between the operating element and the clutch actuating cable, the parts being shown in the position assumed at the beginning of the movement of said mechanism. Fig. 10 is a view similar to Fig. 9 showing the positions assumed by the parts upon the completion of the movement of the clutch actuating mechanism.

Referring to the figures by characters of reference, 1 designates a press box such as shown and described in my patent before mentioned, the same being provided adjacent its inlet end with laterally extending rails 2 secured to laterally extending side walls 2. A slidable base 3 is mounted on these rails and between the walls 2 and provided at its ends with upstanding walls or followers 4 and 4 suitably braced. One or more slotted guides 5 are disposed adjacent and above the feed end of the press box and movably mounted within these guides are upwardly extending projections 6 formed upon a partition 7. This partition is mounted to travel above the base 3 and has depending legs 8 designed to project through slots 9 formed longitudinc ly within the base. Each leg extends upward from a carriage 10 provided with anti-friction rollers 11 adapted to travel within channel bars 12 disposed beneath the base. It is obvious that when the follower 4 is disposed adjacent the inlet end of the press box and the follower 4 is located at a distance therefrom the parti tion 7 is free to travel within the guides 5 and the slots 9 and this partition is designed to aline with either of the walls of the press box while one of the followers 4 and 4 is alining with the other wall thereof.

Extending from the feed end of the press box is a trough-like structure 13 which, as shown in Figs. 6 and 8, is provided with a longitudinal slot 14 in the top thereof in which is mounted a slide 15 to which is fastened the stem 16 of plunger 17. Extending longitudinally from the end of the trough 13 arepreferably two beams 18 between which is secured a block 19 constituting the bearing for a pulley 20. A spring 21 connects the stem 16 with the fixed block 19 so that the plunger 17 is held normally withdrawn from the feed end of the press box 1. A cross beam 21 is connected to the terminals of the beams 18 and a stud 22 extends upward from their points of connection and constitutes the pivot for a sweep 23. A roller 24 is ournaled in each end of the sweep and these rollers are designed to successively swing into contact with the concave head 25 of a pitman 26 pivoted to one end of the stem 16. This head 25 has an angular-arm 27 extending therefrom and under the path of the rollers 24 and a guide stud 28 extends downward from the arm 27 and is designed to travel within an arcuate slot 29 formed in a roller guide 30 which is secured to the

beams

18 and 21. An arm 31 extends from each end of the sweep below and beyond the rollers upon the sweep and, as shown in Figs. 9 and 10, this arm is formed preferably with a concave face 32 for the purpose hereinafter disclosed.

Suitably supported beneath the base 3 ar pulleys 33 which serve to support and guide opposite portions of a cable 34 constituting power transmitting means. The ends of this cable are fastened to opposite end portions of the base 3 preferably by means of hangers 36 extending downward from the base. The intermediate portion of the cable forms a loop which extends partly around and is sup ported by the ulley 2O hereinbefore referred to. This cab c 34 extends through the trough 13 and above deflecting blocks 37 disposed within the trough adjacent the base 3 and those ends of the blocks nearest the pulley 20 are inclined as shown particularly at 38. Secured to the cable 34 between each pulley 33 and the pulley 20 is a block 39 to which is pivotally connected preferably two hooks 40 constituting clutch members. The two blocks 39 and their hooks are so disposed that while one of the blocks is reaching the limit of its movement in one direction the hooks of the other block 39 move upward on one of the deflecting blocks 37. A clutch member in the form of a cross head 41 is slidably mounted within the trough and above the cable 34 and this cross head is provided with an extension 42 located below the plane occupied by the cable 34 and fastened by means of a cable 43 to a coiled spring 44 extending under the press box and designed to hold the cross head normally positioned above and between the blocks 37. Another cable 45 is fastened to the extension 42 of the cross head and extends under the pulley 20 and partly around a pulley 46 located adja cent one of the terminals of an arcuate guide rail 47 secured to the

beams

18 and 21. This rail has a curved slot 48 in which a slide 49 is mounted to travel and said slide has a hanger 50 to which the end of cable 45 is secured. An arm 51 is pivotally connected to the slide 49 and carries a roller 52. A spring 53 is fastened to the slide and holds arm 51 normally in contact with a stop pin 54 carried by the slide. hen the arm is in its normal position the roller 52 is supported within the path of the arms 31 on the sweep I will of course be seen by referring to the drawing that the two

arcuate guides

30 and 47 are formed along lines concentric with the stud. 22, the guide 47, however, being located a greater distance from the stud than the guide 30 so that the rollers 24 are free to rotate along the concave face of the guide 47 without being retarded thereby.

The mechanism herein described is designed to produce a double compression of material such as hay or straw which may be fed to the press. The first of these com )ressions takes place between one of the followers 4 and 4 and the movable partition 7, while the second or final compression occurs within the box 1 and is produced by the plunger 17. As has heretofore been stated the base 3 is mounted to slide laterally in relation to the press box and when in either of its positions the partition 7 alines with one of the side walls of the press box while either the end wall 4 or the wall 4 alines with the other side wall of the press box. For example, if the parts are in the positions disclosed in Fig. 1 the material to be baled is fed between the walls 2 and the wall 4 and partition 7. The sweep 23 is set in motion by horse power or in any other preferred manner and as one of its rollers swings toward the beams 18 it will come into contact with the concave face of head 25 and cause the pitman 26 to force the stem 16 and plunger 17 forward into the press box so that any material in the path of the plunger will be directed into the box. hen the head 25 reaches the limit of its movement along the arcuate guide 30 the roller 24 will move off of the head and spring 21, which is placed under stress during the forward movement of the plunger, promptly pulls backward on the stem 16 so as to quickly return the plunger to its initial position and to bring the head 25 to a point where it can be contacted by the next roller 24 and the operation above described repeated. As soon as the plunger returns to its initial position in the manner described one of the arms 31 moves against the raised roller 52 on slide 49, as shown in Fig. 9, and therefore the slide is caused to move forward within the slot 48 and to pull upon the cable 45. head 41 to pull forward and as this cross head is located normally above the blocks 37 and between said blocks and the base 3, as shown in Fig. 1, it is a )parent that during this movement it will e brought into engagement with those hooks 40 which are resting upon the block 37. This will be apparent by referring to Fig. 6 wherein the cross head is shown back of and in position to engage hooks located upon one ofthe debe free to move across said inlet end untilstopped by the extensions 6 coming into contact with the opposite ends of guides 5. The further movement of the base 3 and follower 4 will be independent of the partition 7 because of the slots 9 which are employed and therefore the material which has been placed between the partition and the follower 4 will be compressed in the path of the plunger 17, this compression continuing until the follower 4 is brought into position in alinement with the nearest side wall of the press box. As soon as this compression between the partition 7 and the follower 4 has been accomplished the slide 49, which has been moving within the slot 48, is brought under the roller 55 and said roller will serve to press the arm 51 downward so as to withdraw the roller 52 from the path of arm 31. Said arm will therefore be free to continue its movement with the sweep while the spring 44 which has been tensioned as aresult of the movement of the cross head 41 and slide 49, will return the slide and cross head to their initial positions. During this return movement of the cross head it will leave those hooks 40 which were in engagement therewith and w ill travel back to its initial position, passing over the other set of hooks 40 which, in the meantime, have been brought into position upon the other defleeting block 37. The material to be baled can then be placed between the partition. 7 and the follower 4 and upon the repetition of the operation above described this material will be initially compressed in the path of the plunger 17.

It will be seen that the mechanism described is very simple, durable, and efficient and produces an'initial as well as a final compression of the material in an expeditious manner without adding to the power required to perform either of the operations.
