BALING-PBESS.

Application filed March 17, 1915.

To all whom it may concern Be it known that I, JULIUS A. SPENCER, a citizen of the United States, residing at Dwight, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to improvements in baling presses, and has reference more particularly to improvements in the mechanism for facilitating the insertion of the division blocks or boards into the press chamber after a sufficient quantity of stock has been introduced and compressed-to make a bale; these division blocks or plates being grooved for the passage of the baling wires and facilitating the application of the latter. Heretofore, devices for inserting these division blocks have been used which comprise a rigid frame structure pivotally mounted on and above the baling chamber and carrying a block-holder, which frame and holder are tilted on the pivotal axis of the frame, by a suitable operating lever, to carry the blockholder and block to a substantially vertical position above the throat of the hopper of the press, so that on the next descending movement of the feeder-head, the division block is engaged by a lug on said feedere head and forced endwise down into the press chamber directly in rear of a previously compressed bale.

The object of my invention is to provide an improved division block holder and an improved frame structure for carrying said division block holder and permitting it to be readily shifted between a forward position wherein it lies across the path of travel of the feeder head and a retracted position wherein it lies above and substantially in line with a wall of the feed hopper.

Another object of the invention is to provide a division block inserter that shall be spring actuated on its'return movement, and shall automatically undergo such return movement as soon as the division block has been forced therefrom into the press chamber.

The device of my invention, its mode of operation, and the advantages secured thereby will be readily apparent to those skilled in the art from the following description, when considered in connection with the accompanying drawings, wherein Figure 1 is a side elevation, partly in section, of a device embodying my invention Specification of Letters Patent.

and showing also such parts of a power operated baling press as immediately cooperate therewith. Fig. 2 is a top plan view of the parts shown in Fig. 1. Fig. 3 is a detail view in horizontal section through one of the side walls of the press chamber, showmg the means for retaining the division block in upright position when inserted into the press chamber. Fig. 4: is a vertical cross section taken on the irregular line 44 of Fig. 1. Fig. 5 is an enlarged vertical section through the division block holder, showing a division block mounted therein, and Fig. 6 is a side elevation view generally similar to Fig. 1, but illustrating the fully retracted position of the division block inserter.

Referring to the drawings, 10 designates the press chamber of a baling press, 11 the plunger or ram thatoperates through said press chamber, and 12 the feed hopper of the press chamber.

13 designates the feeder-head mounted on the usual oscillating arm 14:, and serving to fold a mat or bunch of hay that is thrown into the hopper l2 and force it down into the press chamber 10. On the forward face of the feeder-head 13 is a laterally projecting lug or nose 15, the function of which will hereinafter appear.

10 designates the usual baling chamber that is located ust beyond and forms an extension of the press chamber 10.

Referring now to those structural features wherein my present improyement chiefly resides, 17 designates each of a pair of lugs that are mounted on the opposite edges of the upper side of the baling chamber 16 at points slightly rear of the hopper 12, and 18 designates each of a similar pair of lugs similarly mounted in rear of the lugs 17. Pivoted to the lugs 17 is a pair of upwardly extending arms 19, and similarly pivoted to the lugs 18 is another pair of upwardly extending arms 20. The two arms 19 are parallel to each other, and the other two arms comprises a frame member 22, the longitudinal, edges of which are bent inwardly to provide inwardly facing channel guides 23, best shown in Fig. a, and said frame member 22 is joined to the link-bars 21, in the instance shown, through the agency of widened connector plates or cleats ihe link-bars 21 are united by diagonal brace bars 25,, as clearly shown in Fig. 2.

The block-holder frame 22 is designed to receive a division block 26, the edges of the latter slidably engaging the channel guides 23 of the holder, and the lower end of the division block is supported upon a yieldable spring-backed stop 27, herein shown as pivoted at 28 to the lower end of the holder frame 22 centrally of the latter and extending transversely of said lower end. Rigid with stop 27 is a tail piece 29 in turn pivotally connected to a rod 30, the upper end of which is guided in a bracket 31 on the rear of the holder frame 22. A compression spring 32 surrounding the rod 30 and con fined between the bracket 31 and a washer 33 on the lower end of the rod 30 normally urges the stop 27 across the. lower end of the block-holder in a position to support the block 26, as clearly shown in Fig. 5.

The upper end of one of the arms 19 is extended to form, in connection with said arm 19, an operating lever 3 1; the lower end of the same arm is similarly extended forming an arm 35 to which is attached a tension spring 36, the lower end of which is anchored at 37 to the side wall of the baling chamber. The spring 36 normally maintains the parts of the division block inserter in the relative position shown in Fig. 6, wherein it will be seen that the block-holder is substantially in line with and virtually forms an extension of one of the inclined walls of the hopper. Then a division block is inserted in the holder and the lever 3 lis thrown forwardly, the parts assume the relative positions shown in Fig. 1, wherein the upper end of the division block 26 is in a position to be struck by the lug or nose 15 upon the next descending movement of the feeder-head 13, whereby said block is forced downwardly into the press chamber, forcing the spring stop 27 out of the way as it descends, and assuming the position shown by the dotted line in Fig. 1, wherein it is held by lateral spring stops 38 (Figs. 2 and 3) until it is forced oninto the baling chamber to receive the baling wires by a subsequent stroke of the plunger 11. The spring 36 is so tensioned that the weight of the division block and holder, when the parts are in delivery position (Fig. 1), is sufiicient to overbalance the spring, but when the division block has been forced out of the holder, the spring at once and automatically restores the parts to normal. position (Fig. 6).

From the foregoing, it will be seen that the arms 19 and 20 and the connecting linkbars 21 unitedly form a flexible supporting and carrying frame for the division block, that, by reason of the varying angularity of the supporting arms 19 and 20, not only imparts a bodily movement to the block-holder but also an angular movement during such bodily movement, whereby in one direction of movement the holder is carried to a. position favorable for the insertion of the block by the feeder-head and in the other direction of movement the holder is carried to a position favorable for the reception of another division block, and furthermore, a position wherein, by virtually extending one wall of the feed hopper, it, to that extent increases the capacity and eiiiciency of the latter.

lVithout limiting myself to the precise details of structure and relative arrange ment herein shown and described, I claim:

1. In a baling press, the combination with a press chamber, and a feed hopper communicating with said press chamber, of a division block inserter comprising a block-holder, a flexibly ointed frame structure carrying said block holder and including front and rear non-parallel supporting arms pivoted at their lower ends to the baling chamber at separated points longitudinally of the latter, and an operating lever for said frame structure.
