HAY-PRESS.

SPECIFICATION forming part of Letters Patent No.'634,544=, dated October 10, 1899.

Application filed April 4,1898. Serial. No. 676,459. (No model.)

To all whom it may concern.-

Be it known that I, ELMER J. SHIRLEY, a citizen of the United States, residing at E1 M0- dena, in the county, of Orange and State of California, have invented new and useful Improvements in Hay-Balers, of which the following is a specification.

This invention relates to condensers and feeders for hay-balers, and is applicable to any baler.-

In thedrawings I have illustrated my invention as applied for the double-acting hay,- baler described, in Letters Patent of the United States No. 593,383, issued to me November 9, 1897, and in which a plunger moves to and fro underneath the feed-opening and operates to force the alternate wads or charges in opposite directions to form duplicate bales.

My present invention comprises the combination of a baling-press frame, a plunger playing therein, a lever pivoted to the frame and provided on one arm with a condenserhead to play toward and from the feed-opening, and means operatively connecting the plunger with the lever to move the condenserhead toward and from said opening. Preferably two oppositely-movingcondenser-heads are employed, being mounted on levers, respectively, and arranged to play toward and from each other in the condensing-hopper and on opposite sides of the feed-opening, twov guides being fastened to the plunger to move therewith and two travelers, one on each of said levers and respectively engaging the said guides to be operated thereby to'throw the heads in and out when the plunger is moved to and fro, the said levers being respectively pivoted to the frame on opposite sides thereof and at the lower ends of the leots of the arm, a feeder-armope'rating lever baler embodying my invention. are showninposition' with the feeder raised and the condenser-heads thrown out to admit denser-head is operated the feeder-arm will be operated.

Various modes of connecting thev feederarm to be operated with relation to the movements of the condenser-head may be devised without departing from the spirit of my invention, and in the drawings I have shown .the means'which I regard as most desirable for the purpose, and in this form the guide which is connected with the plunger to move therewith is provided with a bent slotthat is to say, a crooked guideway-having a straight portion in the middle and an oblique portion at each'end of the straight portion and a short straight portion at the ends of the slot, and in this slot a traveler runs, the

same being fastened to and practically form ing one end of the condenser-head lever.

The accompanying drawings illustrate my invention. V

A indicates the baling-frame, provided with a condenser-hopper 13 with parallel sides 1'; 1) extending across the frame at the sides of the feed-opening a.

O 0 indicate two levers pivoted to the frame on opposite sides thereof, respectively,

and respectively provided at their upper ends with condenser-heads c 0, arranged to play toward and from each otherin the hopper on opposite sides of the feed-opening to condense the charges of hay which are placed in the hopper. Preferably the pathof the condenser-heads will extend to a point a little beyond the sides of the feed-opening a.

D indicates the plunger, having the plunger-head d, which works in the balingchamher in the ordinary manner.

E E indicate two guides fastened to the plunger and moving therewith.

c 0 indicate two travelers, one on each of said levers O O and respectively engaging the guides E E to be operated thereby to operate the said levers to throw the heads in and out when the plunger is moved to and fro. Preferably the levers O O are pivoted to the frame at the lower ends of said levers by pivots c, the upper arm of the lever being considerably longer than the lower arm, so that comparatively'a small lateral movement of the travelers will produce a considerable movement of the condenser'heads.

e 6 indicate slots in the guides E E, respectively, and the travelers play in said slots. Each guide-slot is crooked, so that it has a straight middle portion 1 parallel with the path of the plunger and at the ends of said parallel portion oblique portions 2 2, each about equal in length to the length of the straight portion 1 and at the ends of the said oblique portions of the slot short portions 3 3 in a line parallel with the middle portion 1.0f the slot. Then the plunger moves, the guides are carried therewith, and at the middle portion of its movement when the plunger-head is passing the feed-opening there will not be any movement of the condenserheads; but when the plunger-head has fully or nearly passed the feed-opening the oblique walls of the slot will engage the traveler, thus throwing it outward and throwing the con denser-heads inward to the desired position to condense the charge of hay or other material to be baled, and at the final movement of the plunger-head the condenser-heads will remain stationary for a short portion of the beginning of the return stroke, and then when the oblique walls of the slots again engage the traveler the condenser-heads will be.

thrown out, thus to allow a charge of hay or other material to be baled to be placed in the hopper, and the heads will remain out until the plunger-headhas again wholly or pararm F by a pivot g and arranged to play into and out of the feed-opening.

I-I indicates a connecting-rod pivoted to the frame and the feeder .eccentric to the pivots of the arm, preferably being pivoted to the frame and to said feeder, respectively, above the pivots which carry the feeder-arm F and -11 and having one end in engagement with the guide J,"which is carried by the lever O, and is thereby operatively connected with the plunger to be operated by said plunger. K is a connecting-rod connecting said lever with the feeder-arm-operatin g lever H. The guide J is provided with a bent slot j, and the lover I, which is pivoted to the frame by the pivot i, is provided with a traveler d, which runs in said slot. A portion of the slot runs transverse the path of the condenser-head lever C and another portion of the slot runs at right angles thereto and practically parallel with the path of the condenser-head lever. The guide J is in an are drawn from the pivot c" of the condenser-head lever. As the lever O swings to and fro the traveler z" will be moved to operate its lever to operate the connectingrod K to thereby operate the feeder-arm-operatinglever 11' through a portion only of the movement of the condenser-head. When the traveler turns into the transverse portion of the slot j, the feeder-arm is thereby operated during the latter portion of the inward movement and the first portion of the outward movementof the condenser-head. The slot j is arranged so that the feeder-arm will be thrown up clear out of the feed-hopper when the condenser-heads are only partially thrown out, so that the feeder'arm will be out of the way to allow-a charge of hay to be fed into the hopper, and it will be again inserted into the feed-hopper and forced down into the feedchamber before the condenser-heads have fully condensed the wad, the purpose being to carry the hay down in an even wad to extend from top to bottom of the feed-chamber. The feeder-arm pushes down in the uncondensed hay and carries the hay down while the condenser-heads are closing their stroke, so that the final operations of condensing and forcing the wad into the chamber are performed simultaneously and the charge or wad of hay is practically of the same density from top to bottom of the feed-chamber. The feeder-board is preferably forked, as shown, so as to carry the hay down propcrl y.

IIO

M indicates a folder comprising a shaft m, journaled to the frame A and provided with a crank-arm 'm and with a folder-blade'N,

fixed to such shaft and extending into the path of the bale charge.

indicates a stop in the path of the crankarm, and P a spring to yieldingly hold the crank-arm against the stop with the blade in the path of the bale charge. A folder is applied at each end of the feed-chamber, so that when the plunger moves in either direction the folder will properly fold the charge.

The folder is arranged to be readily removed and replaced, and for this purpose the folder-shaft is preferably split with a slit 'm and the folder-blade N is arranged in said slit and with a bent edge n to rest on the top of said shaft, and suitable means are provided for holding the blade in the slit. Preferably the blade is provided with two shoulders, a shoulder n at one end of the blade extending beneath the unsplit portion 'm' of the shaft and a shoulder 41. at the other end of the blade to fit under a sleeve Q, through which the shaft is inserted, so that the blade is held in the shaft by the shoulders.

In practice the opposite sides of the machine are duplicates, so that both of the levers G C operate to actuate the feeder-arm and both condenser-heads move at the same time to condense the charge. \Vhen the condenser-heads have partly condensed the charge, the feeder-arm is operated, and by the time the condensers have completedtheir inward movement the feeder-arm has comand the condenser-heads fully thrown open.

- Then another charge is placed in the hopper and the operation just described is again repeated.
