HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 437,404, dated September 30, 1890. Application and october 28,1889. sentire. $28,475.A momma.)

To all whom it may concern:

Be it known that I, CHARLES O. NEWTON, of Homer, in the county of Cortland and State of New York, have invented a new and Improved Hay-Press, of which the following is a full, clear, and exact description.

This invention relates to hay-presses, the object of the invention being t provide a simple, cheap, and durable press that is applicable for farm use; and to the end named the invention consists of certain novel constructions, arrangements, and combinations Y of elements to be hereinafter fully described,

and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front view of my improved press, parts being shown in section. Fig. 2 is a side view of the press, the lower door being represented as it appears when open. Fig. 3 is a view of the brake employed to check the press. Fig. 4 is a sectional plan View on line .fr of Fig. 2; and Fig. 5 is a sectional plan Y view on' line y y of Fig. 2, the lower door,

however, being shown in a closed position.

In the drawings, 10 10 represent vertical posts that are stepped upon sills 11 11. These posts 10 carry upper cross-bars 12 and 13, the

cross-bars 12 extending from front to rear be p which extend downward through the sills 11,

and a cross-bar 11a, extending between said sills.

Near the upper end of the frame I mount bars 16, which carry yieldingly-mounted j our- Y nal-boxes 17, .which serve as bearingsV for To the upper cross-bars of the frame of the press I secure a plate 25, and to this plate Iv connect the upper members 26 and 26L of toggle-levers A and A', thelower members 0f the toggle-levers (which are shown at 27 and 27a) being connected to a head-block or follower 23.

' The main frame of the press carries an auxiliary frame 29, which extends to the rear of the press and serves as the supportfora shaft 30, upon which there are loosely y mounted gears 32 and 32 and a chain-wheel 31, the

gears and the chain-wheel being provided with clutch-sections, as 33 and 33a. The gear 32a engages a large gear 34, that is carried by a shaft 35, which shaft 35 also carries gears 36 and 37, the gear 37 being engaged by an idler 38, which idler is in turn engaged by the gear 32. The gear 36 engages a large gear.

40, which is carried by a shaft 41, that is mounted in the main frame of the press and carries, in addition to the gear 40, gears 42 and 42a, which said. gears engage gears 43rt and 43, that are carried by a shaft 41a. The shafts 41 and 41a carry chain- wheels 44, 44, 45, and 45, the Wheels 44 and 45" being loosely mounted on the shafts, upon which chain-wheels there run chains 46 and 46a, the chain 46 passing about the wheels 45 and 44 and being' connected to the knuckle-joint of the toggle-lever A, the upper length of the chain passing over the left-hand chain-wheel 19, while the chain 46 passes over the chainwheels 44a and 45a and over the right-hand chain wheel 19. A chain 4S runs upon a chain -wheel carried by a properly-located driving-shaft 49 and upon the chain-'wheel 31, the arrangement being such that the chainwheel 31 is constantly driven forward.

In order that the motion of the chain-wheel 31 may be imparted to the gear 32 or to the gear 32a, I arrange levers 50 50 in connection with the chain-wheel 31, and in connection with the levers I arrange a heart-shaped operating-cam 51, that is pivotally connected to a standard 52, carried by the frame 29. The levers 50 and 50 carryinwardly-extend-v ing and slotted projections 53, the cam 51 riding within said slots. To the lower end of the cam 51, I connect a bar 54, which bar is IOO From the construction described it will be seen that if'either of the levers 55 or 56 be moved in a direct-ion such as to throw the cam 51 so that the sections of the clutch 331 will be brought into engagement the gear 32a will be advanced with the chain-wheel 3l, and the shafts 41 and'41fL will `through the medium of the intermediate gearingbe advanced in a direction such that the chains 46 and 46 will be drawn upon and the knuckle-joints of the toggle-levers A and A will be moved inward and the follower 28forced downward. A reverse motion imparted to the cam will bring the sections of the clutch 33 into engagement, and a reverse motion will beimparted to the shafts 41 and 41a, and the follower will be drawn upward.

By means of the yielding journal-boxes 17, carrying the chain-wheels 19, the chains 46 46 are kept taut during the different positions of the follower, the said bearings and wheels being forced out by their springs wh en the follower descends, the chains during this movement of the follower becoming slack, owing to the inward movement of the togglelevers. l

In order that the travel of the follower may be checked as it moves downward and ap- Y proaches the extent of its throw, I connect a chain 57 to the knuckle-joint of the togglelever A such chain passing about one of the bolt-rods 15 to be connected to the levers 56, while to prevent any undue upward movement of the follower I connect a second chain 57 to the lever 50, passing it about another of the bolt-rods and connecting it to the knucklejoint of the toggle-lever A. l

In connection with the baling-chamber of my press I arrange a door 60, which is connected to the frame of the press by hinges 61, that are slotted, as shown at 62, and in connection with this door I provide a rock-shaft 63, having arms 64, that bear against the door. The rock-shaft 63 is provided with a lever 65, so as to enable the operator to close the door when he so desires. In opening, the door 60 folds outward and downward into a recess formed in the main Iiooring 67; but after the hay or other material to be baled has been placed within the chamber the trap or door is folded upward, so that all loose material will pass into the baling-chamber. The bottom of the plunger 28 and the fixed platen of the press are provided with the usual grooves a b, such grooves being adapted to receive the binding-wires by which the bales are held together. v

The flooring 68 to the rear of the press is lower than the main iioor 67, and just above this floor 68, Imount a door 70, provided with bolts 7l, having racks 72, whi ch racks are engaged by gears or pinions 73, carried by a shaft 74, which has a lever-arm 75, the arrangement being such that by turning the le ver to the left the bolts may be shot forward to engage their keepers 76, as represented in Fig. 5; but by throwingv the lever 75 to the right in the direction of the arrow shown in connection therewith in Fig. 5 'the bolts will be withdrawn from their keepers.

With suchapress asI have above described it is necessary to relieve the bale from undue pressure at the time it is to be taken from the baling-chamber, and to this end I form one end of such chamber so that itwill move outward at the time the door 70 is opened. This side I show at 80, and in order that the side 8O may be moved outward when the door 70 isopened I mount bars 81 in stirrups 82,

the rear ends of the bars extending to aposi' tion such that when the door 70 is opened the bars will be borne upon and forced forward in the direction of the ,arrow shown in Fig.` 5. The bars 8l carry cross-bars 82a, and Yto these cross-bars there are connected chains 83, that extend forward and about the boltrods 15 to be connected to the side 80, so that as the bars 8l are moved, as just described,

the side will be drawn outward and theV end of the bale relieved from pressure; but in order that the side 8O may be returned to its normal position when the door 70 is closed I connect a chain 84 to one of the cross-bars 82 and to the door 70 and pass such chain about a sheave 85, the arrangement being such that the chain 84 will be drawn upon when the door 70 is closed and draw the bars 81 to the rear. As the bars 81 move to the rear they carry eccentric or cam headed levers 86, that are mounted upon the bolt-rods 15, as indicated by the arrows Shown'in connection with such levers, the cam-heads of the levers acting at this time to force the side 8O inward, the arms of the levers being engaged by the bars, as shown in Fig. 5. It is also desirable that when the bale is about IOO to be delivered an initial forward movement be imparted thereto, and to this endI mount a rock-shaft 90 in front of the press and beneath the floor 67. This rock-shaft 90 carries a number of upwardly-extending arms 91, to which slides 92 are pivotally connected, which slides extend inward to a point within the baling-chamber. The shaft 90 is also provided with an operating-lever 93, so that by throwing the lever 93, as indicated by its arrow, the slides 92 will be forced inward and the bale forced outward, as will be readily understood.

To retain the hay in its compressed position after it has been forced downward by the plunger 28, I provide a number of springpressed dogs 94, which are arranged as shownin Figs. 1 and 5.

To guard against the possibility of the descentof the follower at times when the press IIO is being charged, I provide a brake-lever,

a supporting-frame and a follower, of togglelevers arranged in connection with follower, shafts j ournaled within the frame, chain- Wheels carried by said shafts, shafts j ournal-ed in supports outside of the frame, chain-wheels on said shafts, chains passing over said chainwheels and connected to the knuckle-joints of the toggle-levers, and means for operating the shafts journaled within the frame, substantially as described.

2. In a baling-press, the combination, with a supporting-frame, a follower, and toggle-levers arranged in connection with the followers, of the shafts 41 41a, gear- wheels 42 and 43 on the shafts, chain-wheels 44 44a on the shaft 41, chain-wheels 45 45a on the shaft 41, the shafts 18, the chain-wheels 19, mounted on the shafts 18, chains passing over the chain-wheels and connected to the knuckles of the toggle-levers, and means for operating the shaft 41, substantially as herein shown and described. l

3. In a baling-press, the combination, with a loosely-mounted chain-wheel 31, of gears 32 and 32, clutches arranged in connection with such chain-wheels and gears, a means for operating the clutches, a follower, toggle-levers arranged in connection therewith, shafts 41 and 41, chain-Wheels carried thereby, chains which engage said wheels and are connected to the knuckle-joints of the toggle-levers, the chain-Wheels 19, means for operating chainwheel 31, and connections, substantially as described, between the gears 32 and 32a and the shafts 41 and 41% 4. In a Daling-press, the combination, with a head-block or follower, of toggle-levers A and A', shafts 41 and 41, chain-wheels carried thereby, chains which are connected to the knuckle-joints of the levers and engage said chain-wheels, yieldingly-mounted chainwheels 19, over which the chains pass, and a means, substantially as described, for turning the shafts 41 and 41a, as and for the purpose stated.

5. Ina Daling-press, the combination, with a baling-chamber having a hinged side door anda movable end, of sliding bars vhaving their ends projecting beyond the side of the baling-chamber to be engaged by the hinged door and means for moving the end inward or outward from the said sliding bars, substantially as described. v

6. In ahay-press, the combination,with the side 80, of bars 81, chains connected to the said bars, cam-headed levers arranged to bear against the side and to be engaged by the bars, and a means for moving the bars, substantially as described.

- 7. In a baling-press, the combination, with a baling-chamber having a movable side and provided with a hinged door, of sliding bars, connections between the sliding bars and movable side and door, and means operated by the sliding bars for holding the movable side against outward movement, substantially as and for the purpose set forth.

8. In a baling-press, the combination, with a baling-chamber having a movable side and provided with a hinged door, of sliding bars, connections between the said bars and movable side and door, and pivoted cam-levers engaged by the bars and adapted to bear against the said movable side, substantially as described.
