4 SPECIFICATION" forming part of Letters Patent No. 244,822, dated July 26, 1881.

' v 4 Application tiled November 22, 1880. (No model.)

To all whom it may concern:

Be it known that I, ALBERT S. ROBINSON, of the city and county of Albany, and State of 'N ew York,have invented certain new andusedi'erent sizes and, third, to prevent the niaterial that'is forced into the pressing-chamber by the plunger of the machine from being vretracted therefrom by the return movement ot' the plunger. -These objects I' attain by the mechanism illustrated in the accompanying drawings, which form a part of this specification, and in whichy v Figure 1 is aside elevation of my press, with portions of the side broken away fr-the purpose of showing the underlying parts;` Fig. 2, a plan view; Fig. 3,v a vdetached sectional view of the end of the press, showing thegear-wheels not shown in Fig. l; Fig-4, an

enlarged transverse section, at the line w :10,of`

ton-diagrams of the gear-wheels for operat-v ing the double toggle-joints.

As represented in the drawings, a is the,-

press-box, made in a rectangular form,having a pressing'chamber, A,in which the material is compressed directly behind it, and a rearward extension, formingthe baling-chamber A2, (corresponding in size and shape to the transverse'section of the pressing-cl1amber A,) provided with a close top and bottom, but whose sides are simply provided with the top and bottom guiding-strips a, whereby the bales are guided through the chamber, and the opening A4 is formed to facilitate the operation of tying oft' the compressed bale while in the billing-chamber. Aforward extension, A3, is attached to the press-box A for forming a framing for receiving the mechanism for actuatin g the compressing lnechanism.

B is a plunger tted to slide freely in the press-box A, and having fixed thereto a rod, b, that is guided by the cross-piece a. A crosshead, b', is secured to the outer end of the rod b for receiving the inner ends of the plungermoving mechanism. Said mechanism consists of duplex toggle-joints-an upper one, O, and 6o lower one,D-so arranged that when the parts are'extended to force the plunger to the eX- tremity of its stroke into the pressing-chamber the knuckles c and d will lie at their nearest approach to a central line,from which line the said knuckles move outward in` opposite directions until they attain the positions shown in Figsl and 3, when the plungeris drawn backward to the other extremity of its stroke. The inner ends of the toggle-joints are pivoted by 7o the pins c and d', to the cross-head b', and their outer ends are pivoted in a like manner to the cross-piece a2 by the pins c2 and d2.

f Motion is imparted to the toggle-joints by means of the geared crank-wheels E and F, 7 5 whosecenters of rotation are independent'of each other, but ranged in the same continuous line, so that the disks of the wheels will face each other from the opposite side of the press, the wheel E being connected by the pitman e 8o to the upper toggle-joint, C, and the wheel F bythe pitmanf to the lower toggle-joint, D. The wheels E and F are uniform in size,- and are arranged to rotate isochrononsly, but in opposite directions, as indicated by the diagrams, Figs. 6 and 7, tllisuniformity ot speed but opposition in movement being necessary to produce the motions ot' the duplex togglejoints in opposite directions. Motion is imparted to the wheels E and F by a driving- 9o shaft, Gr, through trains ot' gearing, (indicated by the skeleton-diagrams in Figs. 6 and 7.) In Fig. 6 the wheel Eis shown as rotating in the same direction as the driving-shaft, and to et'- fect this the said shaft has secured to it a pinion, g, that gears into a wheel, H, secured to the shaft h', which is also provided with a pinion, h, that gears into the wheel E. In Fig. 7 the wheel F is shown as rotating in an opposite direction to the driving-shaft. rIhis is roo eected by means of a pinionyi, secured to the shaft G and gearing into a pinion, fi', ot' the same size, that gears into the wheel J, secured to the shaft j', which also carries the pinion j, that gears into the wheel F. The gear-wheels H and J and pinions g, i, and i are contained between the plates attached to the framing of the forward extension, A, and the positions of said wheels are indicated by the dotted lines in Figs. l and 3.

K is a hopper fixed on the top of the machine, through which the material is fed into the prcssbox A. At the rear end of the opening for said hopper there is placed a roller, L, provided with longitudinal grooves of angular form, whose deepest incisions are formed by radial lines. Secured to one end of said roller there is a ratchetwheel, Z, into which a pawl, l', engages to prevent the roller from turning backward. Said roller rotates in bearin gs adapted to move vertically against the resistance of springs l2. A second roller, L', of like construction, and provided with the same appliances that are attached to the roller L, is placed in the bottoni of the press-box directly opposite the roller L. Both rollers are arranged so that the beveled side of the grooves lying toward the inside of the press-box will be faced toward the inner end of the plunger B. By this arrangement therollers are adapted to yield outwardly and to rotate on their bearings when an excessive quantity of material is carried forward by the plunger. A guard, M, is placed over the roller L, inside of the hopper K, to prevent the material,as it is fed into the press-box, from clogging said roller.

The sides of the pressbox A and balingchamber A4 are adapted to be adjusted sidewise, for the purpose of making bales of dilferent widths. 'lo effect this purpose there are attached to the top and bottoni of the press the bosses N, having a hole at each end tapped to receive the screws 0, that have bearings, in which they rotate, fixed to the longitudinal frame-timbers of the press. Said screws are provided at their outer ends with miter-wheels P, which engage with like wheels P', secured to the vertical shafts Q at the sides of the press. On the upper end of each of said shafts there is a head, q, for receiving a crank or other suitable appliance, by which the shaft may be rotated to turn the screws connected thereto, so as to move the sides of the press out or in, as occasion may require, and the top and bottom girts, R, are provided with slotted openings for the tie-bolts i', so as to allow for the adjustment above described. When the press-box and baling-chamber are widened, as described, filling-in pieces T are inserted in the top and bottom of the press, and cheekpieces b2 are secured to the sides of the plunger B, so that these several parts will conform in size to each other.

I claim as my inventionl. In a baling-press, the combination, with the duplex toggle-joints C and D,ot` the crankwheels E and F, secured to separate and independent shat'ts,whose centers arc ranged in a continuous line that is common to both, said wheels being arranged to rotate synchronously in opposite directions and connected to said toggle-joints in the manner described, so that each revolution of said wheels will produce a complete movement of the toggle -joints to move the plunger B through both phases of its reciprocating movement, as herein specified 2. In a baling-press, the baling-chamber A,V

provided at two of its oppositelylocated vertical sides with a single opening, A4, and guiding-strips a, for the purpose of facilitating the operation of tying oft' the bale before it is ejected from the press, as herein specified.

3. In a Daling-press, the combination, with the pressing-chamber A', of the balingehamber A2, arranged in relation to the pressingchamber as herein described, and provided at each of its vertical sides with a single opening, A4, and top and bottom guiding-strips, a, as and for the purpose herein specified.

4. The rollers L, provided with angularlongitudinal grooves, as herein described, and having the ratchet l and pawl l', the said roller being adapted to rotate in yielding bearings, and arranged in relation to the hopper lr, as herein specified.

5. A Daling-press provided with adjustable pressing and baling chamber and an adjustable plunger, whereby the press is adapted to produce bales of different widths, as herein specified.

ALBERT S. ROBINSON.
