IMPROVEMENT IN HAY AND vCOTTON PRESSES.

- a Specification forming part of Letters Patent No. 132,566, dated October 29, 1872 Reissue No. 7,982, dated December 11, 1877'; Reissue No. 8,316, dated July 2, 1.878; application filed April 18, 1878.

Drvrsron A.

of the cityofAlbany, county of Albany, and

State of New York, have invented new and nsefulImprovements in Baling- Presses, of which the following is a specification:

Figure 1 is a perspective view, showing the machine completed and in position for operation, and Fig. 2 is atop or planview, illustrating the bale-chamber. Fig.3 is also a top view, showing my improvements and their connections and the manner of operation; and Fig. 4 is a perspective "iew of the end door.

In the figures, A is the hopper for receiving the loose material. B'is the press or receiving box, into which the loose hay is received and pressed. 0 is the bale chamber, into which the hay is deposited after pressing. H is aretain ing-shoulder'for retaining the pressed sections. *1) is a roller to assist in guiding the hay into the press-box. E is the traverser,

. which vibrates within the receiving-box B, and

when withdrawn its forward end forms one of the upright walls of the chamber. F is a crank, forming a toggle in connection with thepitman L. Y

This arrangement would also operate another press of similar construction at the opposite side of the crank, and without expense of power, thus constituting a double machine operated by a common power, the pressing being done is the sweep, to which the .horses are attached.

The power may be applied in a variety of ways. The bale, when formed in the balechamber 0, is tied or bound through the slots I in the box, as shown in Fig. 1, and is then removed or forced out of the end of the press at K by the pressure exerted by the traverser in building up the next bale, as shown, C" bein g the forming bale,an d M the finished bale.

The distance between the head of the press and the traverser, when nearest the head, or,

i-u other words, the distance between the retainers that prevent the hay from expanding and the head, may be greater than the dimensions of the bale-chamber any other way, thus forming the length of the bale toward, the traverser or point of filling, and asthe expan" sion is always in the same direction, toward the traverser or power, it will be proportion ately less as the ends are smaller.

If the bale-chamber were constructed so as to present one of its larger sides to the reciprocating traverser, the expansive forceof the hay would be so great that it could not be re- 7 taincd when the traverser was withdrawn, but would expand back with it; but by feeding the charges or sections into the smaller side of the chamber endwise of the bale the amount of friction secured against the walls of the chamber is so much greater in proportion to the expanding or unsupported surface that but little else isrequired to retain or prevent the hay from "expanding back with the traverser when withdrawn.

In operation the traverser is withdrawn by the revolution of the crank, its forward end forming one of the walls of the press-box,and the hay or other material is fed into the hopper- A, thence into the press-box B forwardpf the traverser. The traverser is now forced forward by the crank, which, with the pitman, forms a progressive toggle-joint vibrated' laterally, the power increasing with the resistance. Y

The operation is now repeated and another charge in a like manner deposited in the chamber against the former one. This operation is continued, each successive'stroke of the traverser forcing another charge within the chamber and condensing the entire mass by just the amount of additional material forced within the chamberbeyond the stroke of the traverser, and the bale is thus compressed to anyrequired solidity, and completed by means of additional charges of material forced within the limits of the chamber. The bale may now be tied off and the door opened. This bale, however, will be rough, in consequence of having nothing compact to commence the bale against.

The operation nowchanges, and the pressing, instead of being performed in the balechamber 0, is completed, or nearly so, in the press-box B, andthe compressed sectionsforced forced behind it within the chamber. After the bale is ejected the door is closed, and the bale further compressed and completed by forcing additional sections of material within the chamber, as in the former case, thus building up the bale cndwise in sections piled one against another, and the operation is thus contin ned,the first bale only being ronghlyput up.

Having thus described my invention, I claim as follows:

1. The press-box Band hopper A, provided with a movable bottom, in combination with the pitm'an and crank or toggle L 1", substantially for the purpose sctf'ortli.

2. The combination of the sweep or horse-
