BALiNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 597,108, dated January 11, 1898.

Application filed May 22, 1897. Serial No. 637,715. (No model.)

To crZZ whom it may concern:

Be it known that I, CHARLES T. OREAL, a citizen of the United States, residing at Edwards, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Billing-Presses, of which the following is a specification.

My said invention consists in certain improvements in the construction and arrangement of parts of baling-presses, whereby various advantages tending to efficiency of operation are secured, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a side elevation of the trunk and mechanism of a baling-press embodying my said invention; Fig. 2, a top or plan view of the same; Fig. 3, a detail side elevation, on an enlarged scale, of one end of the trunk and certain parts of the mechanism; Fig. a, a detail plan view of substantially the parts shown in Fig. 3; Fig. 5, a detail sectional View on the dotted line 5 5 in Fig. 3; Fig. 6, a detail sectional view as seen from the dotted line 6 6 in Fig. '4; Fig. 7, a transverse sectional view as seen from the dotted line 7 7 in Fig. 3;. Fig. 8, a detail perspective view of the tripping mechanism, and Fig. 9 a detail view showing how the division-boards are held in place after being raised to position.

In said drawings the portions marked A represent the driving-shaft; B, an intermediate shaft; 0, the crank-wheel shaft; D, the pitmen; E, the cross-head; F, the connecting or piston rods, and G the baling-trunk.

The drivin -shaft A is mounted in suitable bearings and runs transversely of the balingtrunk G. It is driven by a belt A from some suitable source of power. (Notshown) Upon it is mounted a pinion a, which engages with the spur gear-wheel b on the shaft B, and thus drives the latter.

The shaft B is also mounted transversely of the baling-trunk G and carries, besides the spur-gear 1), two elliptical gear-Wheels B, which engage with similar elliptical gearwheels 0 on the shaft G, and thus drive the latter. These gear-wheels are made of an elliptical form for the purpose of varying the power and speed of the machine at different points of the stroke of its piston or balinghead. As will be understood from an examination of the drawings, these wheels are so arranged that the greatest speed is during the early part of the stroke of the piston or baling-head, while the hay or straw is loosest, and the slower speed, and consequently the greater power, is near the end of the stroke when the bale is being finished and the required pressure is greatest.

The shaft 0, like the other shafts, runs transversely of the baling-trunk G and carries upon its ends the elliptical wheels C, which are also the crank-wheels, and upon which are wrists c.

The pitmen D are of an ordinary form and run from the wrists c on the crank-wheels C to suitable bearings on the cross-head E.

The cross-head E is mounted in slides E, secured on the baling-trunk G, and driven by the pitmen D, which in turn drive the pistonrods F.

The piston-rods F are driven from the crosshead E and drive the piston or baling-headf, being connected thereto through slots in the sides of the baling-trunk G, as shown. Projections g are secured to and extend out laterally from these piston-rods for the purposes which will be presently explained.

The baling-trunk G is of suitable size and shape for the purpose of forming the desired character of bales of hay or straw. Centrally it has a hopper G, through which the hay or straw may be introduced. As this hopper is located centrall-y,the machine,when the other parts are properly arranged, operates, as will be readily understood, while moving in both directions, so as to be engaged in performing the work of making two bales at the same time. It will be understood that this balingtrunk is provided with the usual stops and facilities for tying the bales common to haybaliug presses.

I have provided a special means for introducing division-boards R, which separate the bales into the baling-trunk at the proper time and at the proper point. Secured to the sides of the baling-trunk G are the ways 2, in

which the slides 3 are adapted to travel. Said slides have racks thereon and are adapted to be driven by the pinions p on the shaft 4. Pinions p on the same shaft are driven by other rack*bars,5 which run longitudinally of the baling-trunks G. Upon these rack-bars 5 are relatively mounted the arms 6, which are adapted to be thrown into the path of and beengaged'by the catches or projections 1 on the piston-rods F. In the sides of. the baling-press G are slots through which to insert the wires by which the bales are tied. The division-boards R have the usual grooves to receive the tie-wires, and each also hasa pin a, which, when one of said boards is in place, registers with and projects out into the lower one of the slots 9. As the straw is forced againstthe division-board it is of course forced along inside the trunk, and when it reaches a proper point comes in contact with the inner end of the lever 7, pivoted in brackets or bearings 8 on the side of the trunk, moving said lever on its pivot or fulcrum. The outer end of said lever rests against an arin 9 on a rod 10, and thus when so moved forces said rod back in the direction of the plunger. Said rod is normally held in a direction away from the plunger by the spring .3 thereon, as shown most plainly in Fig. A. The rod 10 has an enlarged head 11, which normally supports an arm 12 on the rack-bar 5, keeping the arm 6 also on said rack-bar out of the path of the projection 1, said arms 12 and 6 being rigidly united orintegrally formed. WVhen, however, by means of contact of the projection r with the levers 7 the rod 10 is forced endwise, the enlarged head 11 passes out from under the arm 12, thus permitting it to fall into a substantially horizontal position and bringing the arm 6 back into the path of the projection l. The

' rotation of the arms 12 and 6 on the rackbar 5 is accomplished by the coiled spring 1 1, wound about said rack-bar and engaging with the hub of said arms. As the operation of the projection 0" is manifestly at a time when the board R, on which it is mounted, is being forced forward, it of course happens when the projection 1 is beyond the arm 6, and so said projection 1 engages with said arm 6 and pulls it with it on its return stroke. There is a projection 13 on the side of the balingpress at the point where it is desired that the travel of the rod R shall cease. Said projection has a wedge or cam face which comes in contact with the arm 12, raising it and forcing the arm 6 over out of the path of the projection 1 on the plunger. The weight of the slides 3 is sufficient to revolve the shaft 4 and its pinions and draw the rack-bar 5 back to its initial position. A division-board is thus automatically introduced each time required at exactly the proper point, needing no other attention on the part of the operator than simply to place such board on the slide 3 whenever it is noticed to be empty, and the I mechanism described will raise it to place at slides G, and these are set in, as may be de sired, by set-screws g. These are adapted to come against the sides of the divisionboards and of the bales as the same emerge from the endof the press.

Having thus fully described my said inven tion, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, with the plunger of a baling-press, of a mechanism for automatic ally introducing division boards into the trunk of said press consisting of a vertical slide having a rack-bar, a pinion engaging said rack-bar, a horizontal rack-bar engaging with a pinion on the same shaft as the firstnamed pinion, a tripping device operated by a projection on the division-board as itreaches the same, and. an engaging arm on the lastnamed rack-bar adapted to be thrown by said tripping device into the path of a projection on the plunger, and means for disengaging said projection and said arm at the proper point, substantially as and for the purposes set forth. 1

2. The combination, in a baling-press, of a division-board having a projectionradapted to travel in a slot in the side of the trunk of said press, a lever pivoted in bearings on said trunk with which said projection is adapted to engage, a trip-rod 10 having an arm 9 operated by said lever, said rod having a raised head, a rack-bar arranged alongside said triprod and adapted to engage with a rack-andpinion mechanism for raising the divisionboards into place, rotating catch-arms on said rack-bar adapted to be normally supported by said raised head but to fall into the path of a reciprocating projection when disengaged therefrom, and a reciprocating part carrying said project-ion, substantially as set forth.

3. The combination, in a baling-press, of the plunger, a rack-and-pinion mechanism for raising division-boards into thebaling-press trunk, a rotating-arm structure on the rackbar, a coiled spring by which it is thrown into the path of a projection on said plunger, and a projection on the side of the trunk having awedge or cam face by which the disengagement of said projection and said arm is effected at the proper point, substantially'as shown and described.

4. The combination, in a baling press, of the plunger, a mechanism for raising divisionboardsinto the trunk of the press, including a raek-and-pinion mechanism, a tripping pro- 'In witness whereof I have hereunto set my jeceion on the division-board, a latch meehhand and seal, at Indianapolis, Indiana, this anism operated. by said tripping projection, 10th day of May, A.
