HAY-PRESS.

BECEFLECATION forming part of Letters Patent No. 334,8l3, dated January 26, 1586.

Application filed June 16, 1885.

To all whom, it may concern:

Be itk nown that l, HENRY F. BLANK, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Hay-Presses, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters and iigures of reference mark ed thereon, which form a part of this specification.

The object of my invention is to provide a hay-press having an improved construction for the sweep and its connection with the follower, the bale-chamber, and the devices for affording frictional resistance to the hay forced through the bale chamber by the plunger; also devices for separating the bales when discharging from the balechamber.

The nature of my invention will be described below, and pointed out in the claims.

In the drawings, Figure 1 is aside elevation, partly in brok en section. Fi g2 is aplan View, partly in broken section. Fig. 3 is a rear view of the press. Fig. 4t is a detail sectional view of the fioor of the press, showing theoperation of the bale-separating hook.

Like letters refer to like parts.

4The press is mounted on wheels, so that it-can be moved from place to place. The main frame consists of two lower beams, A A, resting on the trucks,and the two upper beams,B B,separated from the lower bythe side posts, C (l, of the bale-chamber, the said beams being strengthened at intervals by cross-pieces and bolts.

D represents the sweep, which is forked, the upper and lower sides being held apart by one or more cross-strips, af. The rear ends of the sweep are slotted at b, and there are transverse pins b' through the slots, bearing against rigid pins or bearings c, fastened, respectively, to the top and bottom cross-pieces,c', ofthe frame, and it will thus be seen how the sweep can swing to and fro. (See Figs. 1 and 2.) Between the sides of the sweep extends a rigid bolt, e, having aloose sleeve, e', about itslower half. On the top of this sleeve, and about the bolt, is one eye of the link E, the center of the link being solid, and the other eye playing Serial No. 168,884. (No model.)

about a bolt, d, in the double knuckle-lever F. This lever is centrally pivotcd about a vertical metallic shaft, F', stepped in metallic platesf,

attached to the cross-pieces c', the hubs f' of 55 lever F bearing against said plates. The rear of said lever is pivoted by bolt d' to thepitman G, which is in turn pivoted to the plungerH by means of bolt d2 and bracket The plunger is of ordinary form, except it has a downwardly-inclined groove, g, which in the forward throw engages with a correspondinglyshaped cleat, g', on the roof of the frame, and preventsthe plunger from coming too far for- Ward.

I is the bale-chamber, which should be long enough to include l a pressing-chamber and a bale-compartment. The roof, floor, and sides of the pressing-chamber are solid; but the baledischarge compartment has horizontal slots h h, so that the pressed bale may be readily tied with wire, Ste., before discharging. rEhe rear end of the discharge or wiring chamberis what may be termed a movable friction-head, J. Its inner face is slotted at h h to match slots hh, and from its rear side extends b'ack a geared rack, J', which gears with a pinion, K, on shaft K', which is journaled through the rear frame-posts, C' C. On one end of shaft K' is a rigid pulley, L, surrounded by a frictionband, L', which may be loosened or tightened about the pulley by means of atension-screw, Z. 'The said band is provided with stops or ratchets m m, dividing the former into segments, and` these engage with a clutch, M, pivoted to one of the lower beams at m'.

From the above (see Figs. 1 and 8) it will be evident that the head will yield sufficiently to the hay forced through the chamber I by the plunger, and that while the pulley L cannot turn to any great extent outward before the clutch causes the band to exert a frictionstop, at the same time the pulley is left free to turn inward by the clutch when the head Jis returning to place. By releasing the clutch the bale may be readily discharged, as the pulley and its band will no longer operate.

To separate the discharging bales the following devices are used, (see Figs. 1 2, and 4:) Below the beams A A is pivoted a lever, N, the handle of which plays in aguide, a. To

the upper side of the lever is loosely attached IOO a block, O, (see Figs. 2 and 4,) the upper part of which isT-shaped, and its play is guided by a U -shaped groove, n', ineaeh of the crossstrips P P between the lower beams, A A. rBhe forward end of the T-head -is Wedgeshaped, (see 0,) and when this strikes the pivoted hook R the latter is lifted well up through a slot, r, in the oor of the bale-chamber, forming an effectual stop to what is back of it.

Having fully described myinvention, what I claim, and desire to secure by Letters Patent, is-

l. The combination of the forked sweep,piv `oted to the top and bottom of the frame outside ofthe double knuckle-lever and its shaft, with alink connecting the sweep to the forward end of the leveigthe said doubleknucklelever, a pitrnan hinged to the rear side of it and the forward end of the plunger, and the said plunger, as set forth.

2. The sweep pivoted to the frame at both ends of the fork outside of the doubleknuokle lever and its shaft, and having a bolt provided with a collar, combined with the double-looped link, the double knuckle-lever and its central 25 vertical shaft, the doubly-hinged pitinan, and the plunger, as set forth.

v3. The combination of the plunger having the upper inclined groove, g, with the roof of the frame having the correspondingly-inclined 3o cleat g', and devices, substantially as shown, for operating said plunger, as set forth.

4C. The. combination, with the pressurehead J and the geared rack J', of the pinion K and its shaft K', the pulley L, the friction-band L', 3 5 having ratchets m m and the tension-screw Z, and the pivoted clutch M, as set forth.

5. The combination, with the ioor of the baleohamber, slotted at r, of the pivoted hook R, the laterally-moving block O, having a T- 4o head wedge-shaped at o, and the horizontallymoving operating-lever N, as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
