HAY-PRESS.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed November 1, 1902. Serial No. 129,680.

To all whom it may concern.-

Beitknown that I, JosErH DAIN, a citizen of the United States, and a resident of Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Hay-Presses, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to baling-machines, and is primarily designed for use in compressing hay into bales, and is of the type employing a pull-bar for operating the compressing head or follower as distinguished from that type in which the head or follower is moved by a push imparted through the connectingrod from the usual horse --power. In machines of this type it has heretofore been deemed necessary to employ a more or less complicated system of levers, through which the power was transmitted, in order to suitably move the head or follower, such mechanism being deemed necessary owing to the inability to make a proper direct connection of the pull-bar with the head or follower.

The object of my invention is to provide a construction whereby a direct connection of the pull-bar to the head or follower can be made which will be sufiiciently strong to insure such head or follower compressing the material in the baling-case to the required extent and at the same time to so locate the pullbar that it may extend in a direct line toward the horse-power and yet not interfere with the free compression of the material in the baling-case. To this end I provide the bottom of the baling-case with a central longitudinal slot through which the connection between the head or follower and the pull-bar can move. Inasmuch as a ridge or rib of the material being compressed would be apt to be formed upon the bale by reason of being forced down through such slot in the bottom of the baling-case during the compression of such material, I guard against such formation by providing the upper face of the connection between the pull-bar and the head or follower with a raised central portion, which enters such slot and lies substantially flush with the face ofthe bottom of the baling-case.

That which I regard as new will be set forth in the claims.

In the drawings, Figure 1 is a longitudinal section at line 2 2 of Fig. 1. Fig. 3 is an end View, and Fig. 4 is an enlarged cross-section at line 4 4 of Fig. 1.

Referring to the drawings, 5 indicates a baling-case, to the upper side of which near one end is a hopper 6, through which the hay or other material to be compressed can be fed into the interior of the case 5. The baling-case shown is of ordinary construction, with the exception that it has formed in its bottom a central longitudinal slot 7, which extends to a greater or less degree under that portion of the case in which the hay is compressed, which for convenience will be termed the balingchamber.

8 8 indicate channel-irons suitably secured below the bottom of the baling-case 5 at each side of the central longitudinal slot 7.

9 9 10 indicate a slide which acts as a con.- nection between the pull-bar of the machine and the head or follower, the part 10 being interposed between and suitably secured to the parts 9 and such central part 10 extend ing above the upper faces of the parts 9, so as to enter and close the longitudinal slot 7 as best shown in Fig. 4.

11 indicates the compressing-head or follower, located in the baling-case 5 and having a rearwarolly-extending central web 12. This web 12 in the construction shown is formed integrally with the part 10, although of course it might be made separate therefrom and suitably secured thereto.

13 13 indicate a pair of rollers, each suitably journaled at one side of the web 12 and adapted to roll upon the floor of the balingcase. 14 14 indicate another and smaller pair of rollers carried near the forward ends of the pieces 9 9 of the slide and traveling within the channel-irons 8. With the device in use and the head or follower 11 pressing with great force against the material to be compressed within the baling-case it will be evident that the force exerted will tend to cause the forward ends of the pieces 9 to rise, and by the provision of these rollers 14 14 at such ends such rollers will bear against the upper turned portions of the channel-irons 8, and thereby greatly lessen friction between the parts.

15 indicates the pull-bar, which may be of the ordinary form for such pull-bars or any other equivalent construction and which is connected to the slide 9 9 10 by any suitable means, the means shown being a hook 16 on the rear end of the pull-bar l5 and an eye 17,'

power and the head or follower 11 drawn forward, compressing the hay or other material fed into the case 5 through the hopper 6 and that at regular intervals and in the usual manner the ordinary tripping mechanism of the horse-power will release the pull on the pull- 15 bar and that thereupon such pull-bar and attached parts will through the action of the compressed material in the case 5 be forced back so that the head or follower will be in position to receive in front of it another charge of material, which in turn will be forced forward in the baling-case. The rebound of the pull-bar and the head in all machines of this class is very sudden, and when the connection between the pull-bar and the head or follower z5--isbymeans of a system of levers or other similar connections it follows as a matter of course that the rebound is very much more severe than when a direct connection is provided, as in my invention, for such system of interme- 0 diate levers or other connections in order to be effective must be and is of very considerable weight. By my invention I provide, as I have found by actual use, a very effective baling device of much less weight than the 3 5 machines in general use and one inwhich the jar and shock incident to the rebound referred to is greatly diminished.

By arranging the pull-bar below the longitudinal center of the bottom of' the baling- 0 case and connecting it, as shown, to the head I am enabled to get a very direct and effective pull Without any liability of twisting or otherwise distorting the parts, and by the provision of the raised central portion 10 of the said 5 slide I am enabled to so close the slot in the bottom of the baling-case as to leave no objectionable ridge or rib on the finished, bale, asmight be the case if the hay were free to be forced down through such slot.

That which I claim as my invention, and desire to secure by Letters Patent, is-
