LUTHER TRABUE, OF GIRARD, ILLINOIS.

BLOCK-DROPPING MECHANISM FOR BALING-PRESSES.

To all whom it may concern:

Be it known that I, LUTHER TRABUE, a cit-izen of the United States, residing at Girard, Illinois, have invented a certain new and useful Improvement in Block-Dropping Mechanism for Ealing-Presses, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to baling presses, and particularly to the block-dropping mechanisms used in baling presses for arranging t-he division blocks in operative position in the baling chamber.

One object of my invention is to provide a block-dropping mechanism that comprises means for automatically moving a blockholder into operativeI position with relation to the baling chamber.

Another object is to provide a mechanism of the character described which is Vso designed that the block does not have to be inserted in the blpck-holder at a certain period in the cycle of operations of the plunger or compressing member of the baling press.

.Another object is to provide a block-drop ping mechanism of the character described which is so designed that the operator cannot insert a block in the block-holder when the mechanism which causes the block-holder to be moved into delivering position is in operative position.

Another object is to provide a block-dropping mechanism which is so-sdesigned that a division block cannot be inserted in the block-holder in such a manner that the block will become jammed during the operation of introducing it into the baling chamber. And still another object is to provide a block-dropping mechanism of novel construction which permits a division block to be inserted in the block-holder from either side of the baling press.

Other objects and desirable features of my invention will be hereinafter pointed out.

Figure l is a side elevational view of a baling press provided with a block-dropping mechanism constructed in accordance with my invention showing the block-holder arranged in receiving position and provided with a divisionv block; Fig. 2 is a vertical longitudinal sectional view sho-wing the block-holder in delivering position; Fig. 3 is Specification of Letters Patent.

a similar view showing the plunger of the press retracted and the division block arranged in operative position in the baling chamber; Fig. 4 is a vertical sectional view taken on the line 4 4 of Fig. 2; and Fig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 4.

Referring to the drawings whichillustrate the preferred fo-rm of my invention,

il designates a plunger or compressing member of a baling press which reciprocates in a baling chamber B, and C designates a hopper arranged over the baling chamber so as to receive the hay or material which is forced into the baling chamber by the beater D. A block-holder E which is arranged above the guideway in which the plunger A travels, forms part of the front wall of the hopper C, and at a certain period in the cycle of operations of the baling press said blockholder is automatically moved from its receiving position, shown in Fig. l, into delivering position, as shown in Fig. 2, so that the division block therein can drop downwardly into the baling chamber on the return stroke of the plunger A, as shown in Fig. 3. The block-holder E may be formed in various ways without departing from the spirit of my invention, but in the construction herein shown which illustrates the preferred form of my invention, the blockholder E consists of a substantially inverted channel-shaped member open at both ends and provided with horizontally disposed portions l which travelin guides or tracks 2 arranged adjacent the upper edge of the passageway in which the plunger A travels, the horizontal portions l of said blockholder being reinforced and strengthened by means of brackets 3 connected to same and to the rear vertical wall of the blockholder.

. The means which automatically moves the.

block-holder from receiving position, shown in Fig. l, into delivering-position, shown in Figs. 2 and 3, consists of devices 4 on the plunger A which cooperate with devices 5 on the block-holder during the forward stroke of the plunger. I prefer to provide the plunger A with a pair of upwardly projecting devices 4 arranged adjacent the rear end of same, and I also provide the block-holder E with a pair of pivotally mounted devices or dogs 5 that are adapted to be moved into and out of operative position with relation to the projections 4 on the plunger A, said dogs 5 being arranged adjacent the lower end of the block-holder E between the horizontal portions 1 of said blk-holder.

The means herein shown for moving the dogsor pivotally mounted devices 5 on the block-holder vinto and out of operative position with relation to the projections 4 on the plunger, consists of a pair of pivotally mounted levers 6 which carry a. rod 7 that passes through 'elongated slots 5"L in the dogs 5, and means, such, for example, as a rod 8, connected to one of said levers 7 for rocking them on their pivots so as to elevate the dogs 5 or move them into an inoperative position, as shown in broken lines in Fig. l, or move said dogs in the opposite direction into operative position, as shown in full lines in Figs. 2 and 3. VAny suitable means may be employed for locking the rod 8 so as to hold the dogs 5 in an inoperative position, the means herein shown consisting of A a notch or recess 8a in the rod 8 that engages a stationary member Sb when the rod is pulled forwardly, as shown in broken lines in Fig. 1. The levers 7 are preferably made long enough so that they will extend across the open ends of the block-holder E when the dogs 5 are in operative position and the block-holder is in receiving position so as to prevent the operator from inserting a division block in the block-holder at this time, namely, when the mechanism which causes the block-holder to be shifted into its delivering position is operative or arranged in the path of travel of the projections 4 on the plunger.

The block-holder is provided with means for preventing a division block from being positioned improperly in said holder or arranged in such a position that it will become jammed during the operation of moving the holder into delivering position, the

stop member 9 may be mounted on the blockho-lder in any suitable manner, and any suitable device can be used for holding said stop member in operative position. In the embodiment of my invention herein shown, the bar 9 is mounted in a bracket 1l connected to the outer vertical wall of the block-holder, and the spring 10, which exerts pressure on said bar, is connected to a supporting device 12 which is pivotally connected to the bracket 1l in such a manner that the spring 10 can turn on a vertical axis and thus permit one end of the stop bar 9 to yield slightly during the operation of inserting a division b-lock in the block-holder.

lhenever the operator desires to insert a block in t-he block-holder he moves the rod 8 forwardly so as to move the lever G into an inoperative position with relation to the block-holder and also raise the dogs 5, and after the block has been inserted in the block-holder the rod 8 is released so that` the dogs 5 will move downwardly into the path of the projections 4 on the plunger A. On the succeeding forward stroke of the plunger the projections 4 thereon engage the dogs 5 on the block-holder and thus automatically move the block-holder forwardly into delivering position, as shown in Fig. 2. As soon as the block moves off of the horizontally disposed supporting member 13 on which it rested when the block-holder was in receiving posit-ion, said block will drop downwardly onto the plunger A, as shown in Fig. 2, and on the return stroke of said plunger the division block will drop downwardly into operative posit-ion in t-hebaling chamber B, as shown in Fig. 3, as soon as t-he plunger A passes from under said block. The block-holder and the stop device 9 which coperates with same, are so constructed that the division block can be inserted in the holder from either side of the baling press, and as said stop device limits the lateral movement ofnthe division block it prevents it from being arranged in the holder improperly or in such a position that it will jam against the side walls of the hopper D when the block-holder is moved into delivering position.

One advantage of a block-dropping mechanism of the construction above-de# scribed is that the operator does not have to watch the baling press carefully so as to insert the division block at a certain period in the operation of the plunger or move the block-holder manually into delivering position for said mechanism is so designed that the block can be inserted in the block-holder at any time when said holder is in receiving position and left therein until it is desired to introduce the block into the baling chamber, at which time the operator releases the rod S so as to set the dogs 5 in operative position to be engaged by the projections 4 on the plunger on the succeeding forward stroke of the plunger. Another advantage of such a block-dropping mechanism is that the division block cannot be inserted therein at a time when the mechanism which causes the block-holder to be moved into delivering position is operative, this being due to the fact that the levers 6 are so proportioned that they extend across the open ends of. the block-holder when the dogs 5 are in operative position. And still another desirable feature of my improved block-dropping mechanism is that the blocks can be inserted in the holder from either side of the press and Without liability of inserting them too far or arranging` them in such a position that they Will during the operation of introducing them into the baling chamber. The outward pressure which the material in the hopper C exerts on the block-holder tends to move said block-holder back to receiving position, but in case said blocloholder has not been restored completely to receiving position at the time it is desired to introduce a block into same,

the operation of pulling the rod 8 forwardly to raise the dogs 5 causes the block-liolder to be restored completely or moved clear back to receiving position. The rod 8 is detachably connected to the lever 6 so that said rod can be arranged on either side of the press, both sides of which are provided With devices 8b Jfor locking the rod so as to hold the dogs 5 in an inoperative position.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:
