ings of said patent fully describea complete' press, consequently ofthe press is necessary so fication isV concerned.- As in`the presslde'- scribed in my former patent, above referred to, a longitudinally reciprocable plunger 11, is slidably mounted in the body of said press for compressing the hay into bales, said plunger being reeiprocated by power transmitting connections, here shown in the Aform yof a pitman 12, running from the no further description far as this speci-` plunger 11, to a pair of gear wheels 13, lo-

`cated at the front end of the press and vdriven continuously in one direction by suit- .able gearing.

In the form of wire' passing mechanism chosenl to illustrate the application of the invention, I employ a plurality of wire passers 15, in the form of bars that extend Aat an oblique an'gle with respect to the path `of travel of the plunger,

yas seen' in Fig. 2. The number of wire passers employed, correspond with 'the number of bale tie wires that it is desired to use on each bale. The

wire passers move through slots 10a, in the side wall of the press which wall may be reinforced along the slots by U shaped angle irons 1 6. The plunger'is formed with from its vend face, and in alinement. `with the wire pass ers. 4The working. ends of the wire passers have wire receiving fingers 15a, and the outer endsof said wire passers are connected `by 4a vertical' bar 17, which has journaled Vthereupon 'a roller 18, arranged to "i'un upon a`f guide bar or rod 19, secured fastened to the side wall of to move longitudinal of themselves, and

their movement is effected at the proper inp tervals by driving mechanism, operatively.

connected with the gearwheelsl.

The form of mechanism for'intermittently reciprocating the wire passers, as illustrated in the drawing, comprises pinions 421, seJ cured upon a vertically extending shaft 22, and meshing with rack teeth 23, on passer formed on each bar and overhangs the teeth of the racks, and the pinions 21, are provided atrtheir lower sides with anges 25, that underhang and partially support the wire passer bars 15; The `shaft 22, is jour naled in brackets 26, secured to the body the wire.. bars. As shown a flange 24:, is-

of .the pressA and said shaft has secured pinion '27, which meshes'with a 'stant that the forward passes the far end of the wire passers. The

` rack bar 28.

ythe segmental rack 32,

rack bar 28, guided to move longitudinally of the machine, as for instance by means of brackets 29, 30. In the form shown, the rack bar 28, has secured thereto an extension 31, that slides in the bracket 30.

' The rackbar'28, is intermittently reciprocated by a segmental rack 32, secured uponthe spindle -of one of the ge-ar wheels 13, Aand arranged to engage and rotatea pinion 33, carried upon a swinging support 34.` The segmental rack 32, is of such'extent as to give one complete rotation to the pinion 33,'and its forward end is so located with respect to the pivotal point of the pitman on the gear'wheels 13, that it comes into mesh wlth the pinion 33, at the inend of the plunger movable support 34, for

the pinion 3.3, is

shown as fulcrumed at its upper end upon a bracket 35, secured to the press body and is preferably of U-shapedv form, as shown' Fig.`4, the two legs'thereof straddling y e whic is rigidly secured to far end of the shaft 36, is shown as vided with a crank arm 37, t-he free end of which is connected by a pit-man 38, to the l The proportions of the parts are'such that one complete revolution of the crank arm 37 around its fulcrum makes one 'complete forwardand backward movement of the rack bar 28, thereby imparting an oscillatory movement to' the pinion 27, shaft 22, and pinions 21, and consequently moving the wire passers through the ody of the press and back again to the position shown in full lines in the drawing. While the support 34, is in the position shown in Fig. 1, the segmental rack 32, may ass by the pinion 33, without engag. ing t e same, but as soon as the plunger 11, is moved forward o n the -last stroke in compressing. a bale, then the pinion 33, is moved into position to be engaged by and mechanism is provided for eil'ecting this result, said mechanism being capable of receiving its motion mechanically, by the action of the press mechanism, or by hand as is desired. In the form shown, I provide acrank arm 40, and a link 41, pivoted together at 42, the shaft 40, ofthe crank arm 40, being journaled in a bracket 43, secured to the` underside of the.press, and the link 41, 'being pivoted to t-helower end of one of the legs of the support 34. In inoperative position, said crank arm 4 and'l1nk"41, lie at an angle to each oth r as shown in Fig. 1, but when the pini n 33, is to be moved into operative position/for engagement with the segmental rack, then the crank arm 40, is swung lupward in the direction of the arrow, thereby swinging 11p-the link 41, lengthening the distance between the far ends of the pinion. The

pro-

-safety device is also c and consequently swmgmgthe support 34, uponv its fulcrum and moving the pinion 33, 'over' into operative position. iI h ave shown the link 41, as having its free -endlbent `transversely for engagement with the crankarm 40, to limit the upward movement of the frank armand link. The movement of the support 34, is suiiicient to bring the pinion 33, into apo'sition in which the segmental rack 32, will -run into mesh therewith, du'rin the next ,'cycle of rotation of the gear whee s 13. v

A simple form of mechanism for rocking the crank arm 40, is illustrated in my prior Patent No. 526,883, issuedOctober 2, 1894,- for improvements in 'baling presses, but in the drawing furnished herewlth I have simplified that form somewhat and as shown, it comprises a toothed wheel 50, mounted upon a shaft 51, journaledin brackets-secured to the underside of the press body, saidr toothed "wheel projecting --up into the -chamber of the press 1n position to be engaged by a bale of hay as' it is forced through said chamber by the plunger 11. The shaft carries an arm 52, which is arranged to strike against the end of a rod Connected'at itsother end with a crank arm 55, of the crank shaft 40. A compression spring 56, is shown as confined between an enlargement on'the end of the rod 53, and the bracket 54, for returning the parts to the position shown in Fig. 1, after they have been moved by the arm 52. The circumference of the toot-hed wheel is equal to thelength of the bale 'of hay, and is consequently given one complete rotationbv the movement of a bale pastl the toothed wheel. The parts are so proportioned and adjusted that the arm 52, strikes the rod 53, and throws the pinion 33, into operative position at the time that the plunger 11, is making its last compression stroke to '.finish a bale.

, To guard against injury in case the pinion 33, is accidentally moved toward opera.- tive position, I provide a safety device upon the segmental rack which is arranged to prevent the gear pinion from being fully moved into operative position whenever the segmental rack is passing said pinion; the arranged to hold the pinion in mesh with the rack at the proper time. In the form shown in the drawing, said safety device comprises a-segmental guide strip 45, arranged `*concentric with respect to the axis of rotation of the segmental rack and supported from the rack as by brackets 46. Said segmental guide 45, is so positioned relative to the axis of rotation, that under normal conditions the guide 45,' will pass between the protruding end of the shaft 36, `and the shaft ofthe segmental rack, so that in case the pinion 33, is moved 53., carried by a 'bracket 54, at one end and ,rguide 45.

moved into operative position after the seg-v proaches the pinion,

tion,

'in the direction to throw it into mesh with the segmental rack while. the latter passes the pinion, the guide 45, obstructs such movement by reason of the fact that the protruding end of the shaft 36,' strikes against the outer face of' the segmental When, however, the pinion 33, is

mental rack has completely passed by the pinion and before its forward end appasses on the far side of the protruding shaft, thereby preventing the accidental disconnection between the pinion and segmental rack until-the rack has completed the operation of rotating the pinion.

- In connection with the crank arm 37, is 'shown a dog 47, carried by the support 34,

fa'nd arranged to prevent the crank arm 37,

and pitman 38, from swinging down after then the guide 45,'

the crank arm has made a complete revolu the dog being so arranged that the crank arm may pass by the same on its upward movement, but I is prevented from swinging back. l

In the operation of the device, hay is fed into the compressing chamber of the baling press as usual, and the plunger reciprocated by the power, transmitting mechanism. The bale tie wires y(from the reels) are let in through the slots 10a, and carried through the press to the opposite' side of the machine where they are secured to the wires coming from reels on said opposite side.. The hay 'is it is compressed and forced backward b v f the plunger, moves said bale tiewires back by ipassing a e chine,

and in line with the lingers of the wire pass- 'ei's and whenthe last stroke of the plunger. is made to finish the bale, the pinion 33, is moved into operative position, the segmental rack comes into mesh with said pinion, gives the same one complete rotation, thereby reciprocating the rack bar 29, rotating the pinion 27, the shaft 22, and pi ion 2l, thereon, in a forward and reverse direction, consequently moving` the wire passers l5, through the slots of the plunger, through the ,body of the press and back again, thereloop of the wire through the press to the other sidewhere said loop is lthereafter severed in two and the severed ends knotted or otherwise secured to the ends of the other wireon the o posite side ofthe press. It is to lbe notice that inasmuch as tlie end face of the plunger passes the extreme end of the wire passers before they begin their movement across the maers forward and back takes back of the end face of the plunger, and that all of said movement takes place during the time that the/end face of the plunger travels from a position nea-r the end o f its compression stroke to the extreme limit of its stroke and the entire movement of the wire pass- `ger having back again. By reason of the fact'that'the wire passers e extend Aon'ian obliqueangle with respect to the plane of .the press',it 1s possible .to pass the wires to .the proper point on the opposite side of the press by movements of said wire passers which are comparatively slow,

length of time at the end of its compression stroke, and this is particularly desirable in presses of this type.

, I realize that various alterations and modifications of thisA device are possible without. departing from the spirit of my invention, and l do not'therefore desire to limit myself to the exact form of construetion shown and described.

I claim as new and desire to secure by Letters Patent:
