IMPROVEMENT IN BALING-PRESSES.

Specification forming part of Letters Patent No. 178,464, dated June 6, 1876; application filed March 24, 1876.

Teen whom it may concern:

Be it known that I, JAcoB Peron, of San Leandro, Alameda county, State of California, have inventedan Improved Baling-Press and I do hereby declare the following description and accompanying drawings are sufficient to enable 'any personskilled in the art or science to which it most nearly appertains to make and use my said invention or improve ment without further invention or experiment.

My invention relates to certain improvements in that class of upright baling-presses in which the follower moves from the bottom upward, so as to compress the substance to be baled in the upper end of-the press, as hereinafter more specifically described and claimed.

In order to explain my invention, so that others will be able to understand its construction and operation, reference is had to the accompanying drawing, in which- Figure 1 is a perspective view of my press. Fig. 2 is an enlarged section of one end of the fulcrum.

Let A represent the body of an upright press. The top or cover B is hinged to one side of the press, so that it can open upward, like a door. When this door is closed it forms the top of the press-box, and receives the up ward pressure of the substance which is being pressed. It therefore requires to be securely and strongly fastened down when closed. To do this I hinge a strong metal loop, O,'to each forward corner of the top of the press, so that when it is turned up to a vertical position it will encircle the projecting ends (I d of the centric roller will rest in this concavity, and

by turning the roller so as to press the lever or handle down upon the inner edge of the plate the eccentric roller will clamp the timher and fasten'the door firmly in its closed position. This fastening is easily released by raising the lever f, so as'to unclamp the eccentric roller, and then casting the loop ofi from over the ends of the timber, thus freeing the door and allowing it to be opened.

H H are the side doors. In some upright presses only one side door is used; but I have represented one on each side of the press-box.

The fastening is the same for each of the doors, and it consists of a vertical bar, I, the

ends of which are formed into cranked journals, and these journals bear in the projecting ends of the cross-timbers J J of the hay-press opposite the swinging end of the door, so that when the door is closed the bar may be partially rotated toward the frontof the press, and as its ends are cranked it will be brought against and directly across the outer ends of the door frame or timbers.

A latchJever, K, has one end pivoted to the bar, and when the bar is in position to fasten the closed door the end of this latchbar is caught behind a hook, I, on the doortimber, thus securing the bar from being turned by accident. This latch-lever also serves as a lever or handle for operating the bar. This fastening is also quite easily operated, even when the pressure of the bale is against the door.

In constructing the follower of my haypress I use a longitudinal center-bar, m, which may be made of wood or metal, or a combination of wood and metal. This bar is long enough to project through the vertical slots in the sides of the body A at each end, and to its ends-I attach the toggle-levers, as hereinafter described.

On each side of this bar, inside of the press, I place a strong Wooden bar, a, and connect the three bars together at two or more points by an inverted V-shaped bolt, 0, the legs of which pass down through the outside bars, while its middle passes over the middle bar. I then draw the bar firmly down by means of nuts screwed upon the ends of the bolt. The slats are then fastened transversely upon the upper face of this bar, thus forming an exceedingly strong follower.

For raising the follower I use two pairs of toggle-levers, and operate them by means of i a right-and-left-hand screw.

I am aware that toggle-levers have heretofore been operated by means of a screw for raising the follower of a hay-press; but the ATENT Qrrren.

toggles were attached to the middle of the follower, and the nuts which moved on the screws for straightening the toggles traveled toward each other.

P represents the horizontal screw of my press, one-half of which is provided with a right-hand screw-thread, while the other half is provided with a left-hand screw-thread.

Q Q are the nuts which move on the screw 1., and operate the toggles. The upper arm S of each toggle has one end secured to the nut, while its upper end is secured to the outer extremity of the follower, instead of to the middle, as heretofore, while the lower arms are connected with the nuts Q at their upper ends, their lower ends being secured to a strong shaft at the bottom of the pressframe, and directly below the outer ends of the follower.

It will thus be seen that in order to straight en the toggle arms or levers the nuts Q must move away from each other and toward the .outer ends of the screw-rods.

For supporting the screw-shaft I employ brace-arms 1" 1", which connect the toggle-arms t and s with a box, '0, which supports the outer ends of the shaft. The boxes 1) remain stationary, while the toggles s t and arms 1" 1" open and close as the toggle-arms move upon the screw.

By connecting the togglelevers with the outer ends of the follower I get a more uniform pressure upon the bale, especially if the follower is strong and rigid, and abale of hay or other substance has a better appearance if the corners are well pressed, which cannot be done if the pressure is only applied at the middle of the bale.

By these improvements I greatly simplify the working or movable parts of the press, so that they can be quickly operated, and yet provide substantial devices for withstanding the wear and'tear to which hay and other similar baling presses are of necessity subjected.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The top door or cover B of an upright baling-press, having the transversely-grooved metal plate or shoe 9 secured upon its projecting ends d d, in combination with the metal loop 0, with its eccentric roller or cross-bar e, and lever or handle f, substantially as and for the purpose described.

2. The improvement in followers for baling-presses, consisting in constructing the main beam of the follower of three parallel bars or pieces of timber, connected together by an inverted V-shaped bolt, 0, constructed and applied substantially as and for the purpose described.

3. In combination with the toggle-levers s t, nuts Q, and followers, the brace-arms *r r and boxes 12, arranged to support the outer ends of the screw-shaft and steady the movement of the toggle-levers, substantially as above specified.

JACOB PRICE.
