BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 439,335, dated October 28, 1890. Application filed November 30, 1888.Y Serial No. 292,192. (No model.)

' Quincy, in the county of Scott and State of Illinois, have invented certain Improvements in Ealing-Presses, of which the following is a specification.

This invention relates to that class of socalled continuous presses in which the charges are introduced through aside opening into a trunk or body, where they are carried forward successively by a reciprocating plunger or traverser and added to the preceding mass which is gradually delivered from the opposite end of the trunk.

The principal objectsrof the invention are to give the operator perfect control of the action of the plunger and to economize the application of power to the machine.

In the accompanying drawings, Figure lis a longitudinal section through a press constructed on my plan, on the line o0 of Fig. 2, the extreme delivery end, which is of ordinary construction, being broken away to reduce the size of the ligure. Fig. 2 is a front end elevation of the machine. Fig. 3 is a side view of the primary driving-shaft and its connections.- Fig. 4 is a cross-section of the same on the line y y. Figs. 5 and 6 are respectively a side view and a plan view of the sectional safety-pitman.

Referring to the drawings, A represents the horizontal trunk or body of the machine, constructed, asusual,with a strong external frame` work and a top opening ct, into which the successive charges of hay are introduced, and from which they are driven one after another through the trunk toward the delivery end, commonly known as the rear end.

B represents the plunger or traverser arranged to reciprocate within the trunk, past and beyond the eedppening, for the purpose of carrying the charges rearward and adding t them to the accumulated mass beyond.

In presses of the present type as ordinarily constructed the plunger or traverser is of box-like form, and consequently its front end when retracted must stand forward of the driving-gear, which necessitates the construction of a very long frame to accommodate all the parts. Instead of constructing the plunger in its usual form, I build it, as shown, with a compar. tively thin vert-ical face, and with a horizontal arm b extending :rigidly forward from its upper side. This arm runs at the upper side within the top `of the trunk or chamber and is guided thereby. On the under side the arm overrides and is supported by one or more rollers b4, secured to theinner sides of the frame. In place of the'two rollers b4 a single roller extending across the inside of the frame, or a cross-bar in the same position, will answer the purpose, the only requirement being that the arm shall be guided and supported on the underside so as to prevent it from dropping downward. The rollers or other guides are so located as to admit of the arm b passing over them and of the face of the plunger retreating until it nearly reaches them, as shown in Fig. l. Owing to the fact that the plunger is without the usual forward extension at the under side, it may pass rearward, as shown in Fig. l, over the top of the driving-gear- This permits the driving-gears to be placed farther rearward than usual-in other words, closerl to the feedopening than in ordinary machines--and consequently enables me to materially reduce the length, width, and expense of my press. If desired, one or more rollers be may be placed at the lower edge of the plunger to travel ou the floor of the trunk, and thus reduce the friction. As the plunger advances it will sometimes happen that the charge before it will rise above its upper edge and prevent its advance beyond the rearward side of the feedopening. To overcome this difficulty, I provide the plunger at the top with a vertical yielding plate b, which may be constructed and applied in any suitable manner. As shown in the drawings, the plate, preferably of metal, is hinged to the top arm of the plunger at b2, and supported at its rearward end by spiral springs b3. y Under ordinary conditions If the hay overrides its rearward end during its advance, it will yield in a downward direction and permit the plunger to continue its movement.

The plunger is actuated by a pitman C, jointed at one end thereto and jointed at the opposite end to an arm D, mounted on a horizontal shaft E, sustained firmly in the frame.

D, and mounted at theopposite end on a the plate is held against the top of the trunk.

IOO

A pitman F is jointed at one end to the arm crank-pin g. This pin is attached at its opposite ends to two vertical gear-wheels G and G', which are mounted within and at opposite sides of the frame on short studs or journal g', fixed thereto, this arrangement perinitting the crank-pin and the end of the pitman F to make a complete revolution between the two wheels.

The wheels G and G', which are entirely independent, except as to the connecting-pin g, are driven, respectively, by pinions I-l and H', mounted within the frame near `opposite ends of a shaft I, which latter is seated in stationary boxes or bearings at the base of the frame.

The shaft I, which is the primary drivingshaft, is provided at one end with a universal joint` or coupling J, by which it may be connected to the tumbling-rod of a horse-power or`to any other suitable driving-shaft.

As it is sometimes desirable to make the di'ivingconnections at tlieend of the machine, the shaft I is provided at one end with a bev.- eled pinion t', engaging a pinion t" on the end of a shafti2, which latter is extended lengthwise of the frame through suitable bearings thereon, one end being exposed and provided with a suitable coupling Vhen the shaft I is re volved, its pinions rotatethewheels G G',which in turn carry the crank-pin gin a circular path. The crank-pin, through the pitman F, actuates the arm D and pitman C, causing the plunger or traverser to move forward and then retreat at each revolution of the Wheels G G'. As the plunger or traverser advances the pitman C and arm D act after the man- -ner of a toggle or knee-lever.

In order that the driving-pinions may be thrown out of action and the motion of the press arrested without stopping the drivingshaft, the pinions H H' are mounted to turn loosely on the shaft and are adapted to interlock, respectively, with the clutch members 7L 71,', splined to the shaft to move endwise thereon. These clutches may be toothed, or they may be of the familiar frictional type, as preferred. Each clutch member h 7L is provided with the usual hub having the circumferential groove, and the two clutch members are thrown into and out of action simultaneously by an intermediate lever h2, having pivoted plates h3, which engage the grooves in the hubs of the clutch members h h'. A rod h4 extends from the lever to any point from which it may be conveniently operated by the attendant.

The shaft I is provided at one end with a large spur-wheel K, fixed thereon and engaging a pinion L on one end of a shaft M, which is extended transversely through the machine and provided at the opposite end with a heavy y-wheel N.

In order to feed the successive charges into the machine, I mount on the top of the frame near one end levers O, provided at one end with the feed-blades P and connected at the opposite ends by rods Q to an arm d, extending rigidly and laterally from the arm D. The relative positions of the parts are such that the arm d and rods Q cause the feedplates P to desc-end through the feed-opening when the traverser is retracted.

The rods Q are constructed in a telescopic manner at the upper end and provided with spiral springs q, tending to elongate them, or are otherwise provided with springs to admit of the lever O yielding in an upward direction in the event of the feed-blades encountering an excessive resistance.

It sometimes happens in practice that the resistance offered to the advance of the plunger is such as to cause undue strain on the operative parts. To avoid danger from this source, I construct the pitman F in two'parts, its body portion f being inserted endwise be# tween the two plates f', which'form its head. These plates, which encircle the crank-pin, are drawn forcibly togetl er on the portion f by bolts f2, the friction being suoli as to maintain the connection of the parts under ordinary circumstances. When the strain is excessive, it will overcome the friction and the body portion f will be drawn out from between the plates f', thus disconnecting the driving-gear from the plunger.

It is to be observed that in the operation of my press power is applied, primarily, to the pinion-shaft I, and transmitted thence through its pinions directly to the wheels G G', which carry the crank-pin for operating the toggle mechanism of the follower.

It will be noticed that motion is transmitted from the gear on the pinion-shaft I directly to the shaft which carries the fly-wheel, so that the fly-wheel receives motion from the driving-shaft independently of the gearing which actuates the plunger. The fiy-wheel is made of great weight and the gearing so proportioned as to impart very high velocity thereto during the retreat of the plunger. The momentum of the fly-wheel is applied through the intermediate gearing to assist in advancing the plunger. Thus it is that the power applied during the retreat of the plunger and while the parts are running free is rendered available in the compression of the hav.

Owing to the fact that the ily-wheel remains in gear with the drivingshaft, although the plunger-operating gear is thrown out of action` I am enabled to continue the motion of the drivingshaft, although the plunger-operating gear is driven intermittin gly. This is found in practice to be a great advantage.

I am aware that the primary driving-shaft of a baling-press has been provided with ilywheels and connected with the pressing mechanism by an intermediate clutch, so that the shaft, continuing its motion, would act to turn the fly-wheels and thus store up energy during the time that the pressing mechanism was out of action, and to such construction I lay no claim.

IIO

The peculiarity of lnyinvention lies in the fact that the driving-shaft is connected on the one hand through a clutch mechanism with the pressing devices and on the other hand through intermediate speeding gear with the fly-wheel, so that the ily-wheel will receive a much higher velocity than the driving-shaft. This arrangement is highly advantageous in'that the speed of the drivingshaft is and must be comparatively slow, so that when fly-Wheels of practicable size are applied directly thereto a few revolutions of the shaft will give them their maximum speed, after which there is no further conservation of energy. When, however, the y-wheels are geared to the driving-shaft, as herein shown, a considerable time is required for them to attain their maximum velocity, and thus the accumulation of energy may be eX- tended over practically the entire time between the binding of one bale and the next.

Another advantage in my arrangement lies in the fact that the iiy-wheels, having high velocity, act through intermediate powergear to impart a comparatively slow motion to the pressing devices, the application of the accumulated energy being thus distributed over a considerable period of time and the parts enabled to act more satisfactorily than would otherwise be the case.

l am aware that the operating-pit-man of pressing mechanism has been composed of separable parts united by a wooden breakpin intended to be sheared off by excessive strains, and to this construction I lay no claim, my invention in this regard being limited to a pit-man the separable parts of which are held together solely 'by frictional contact, so that they may be separated without breaking or shearing action and reunited without the employment of new or additional parts.

Having thus described my invention, what I claim is l. In a baling-press of the type herein described, the horizontal trunk or chamber, gear-wheels G G at the front end, the plunger or traverser having at its top the rigid front arm to override the gear, the stationary guide beneath said arm, a pitman jointed to the plunger, and suitable intermediate connections for transmitting motion from the Wheels G G to the pitman, substantially as described.

2. In a baling-press of the type herein described, the driving-shaft, the plunger, and intermediate power-gear and its connections for slowly advancing the plunger, clutched to the driving-shaft that it may be disconnected therefrom at will, a ity-wheel, and intermediate speeding gear permanently connecting the fly-wheel with the driving-shaft independently of the gearing through which the plunger is operated,whereby the drivin g-shaft may be continued under motion and caused to impart a high velocity to the ity-Wheel, while the plunger-operating mechanism is ont of connection and the momentum of the iy-wheel thereafter rendered available to slowly=ad vance the plunger through the intermediate power-gearing.

3. In a baling-press, the plunger, the pitman C, and arm D for operating the same, the pitman F, the two gears G G', and the crankpin for operating pitman F, the driving-shaft I, its pinions H H', and their clutches for driving the before-mentioned gears, the flywheel, its shaft and pinion, and the gear K, mounted on the driving-shaft.

4t. In a baling-press, the plunger, the plunger-operating crank, means for turning the same, and an intermediate pitman composed of two separable parts united and held together solely by frictional contact, substantially as described, whereby the parts are permitted to separate and relieve the crank in the event of the plunger meeting with excessive resistance.

5. In a baling-press, and in combination with a plunger and an operating-crank, means for turning the same, an intermediate pitman consisting of the body portion f, the two portions f, adapted to encircle the crank-pin and embrace the portion f, and the tightening-bolts f2, connecting the parts and holding the same 'in frictional contact with the body portion,

whereby the parts may be adjusted to separate when the plunger meets a greater or less resistance.

In testimony whereof I hereunto set my hand, this 12th day 'of November, 1888, in the presence of two attesting witnesses.
