B'ALING-PRESS.

SPECIFICATIN forming part of Letters Patent No. 533,353, dated January 29, 1895.

Application filed December 1, 1893. Serial No. 492,491- (No model.) A

To a/ZZ whom, t may con/cern:

Be it known that I, CHARLES HARMAN FIELD, a citizen of the United States, residing at Dalton, in the county of Whitfield and State of Georgia, have invented a new and useful Ealing-Press, of which the following is a specification.

My invention relates to improvements in baling-presses, the objects in View being to produce a balingpress of simple construction and adapted to be operated by horse, steam or other power; to provide a convenient mechanism for operating the plunger, which is so constructed as not to increase the draft on the horse at the final portion of its stroke, but which will be steady, smooth, and even, and which will cause the plunger to move fast at the beginning of the stroke and gradually decrease its speed toward the'end of the stroke and at the latter time increase the leverage, whereby a greater amount of poweris yielded at the time that the packing of the bale takes place; and, furthermore, to absorb the rebound of the plunger, preventing the shock to the machine as caused by the rebo'und and gradually returning the plunger to its position for asubsequent stroke.

Other objects and advantages of the invention will appear in the following description and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings:'-Figure 1 is a perspective view of a press embodying my invention. Fig. 2 is a sectional view through the balingchamber, the power mechanism being shown in side elevation. Fig. 3 is a transverse sectional view of the press in advance of the tucker-roll. Fig. 4: is a detail in perspective of the tucker-roll and its su pport. Fig. 5 is a detail in perspectiveof the powermechanism, the operating lever being removed and indicated by dotted lines.- Fig. 6 is an inverted plan view of the lever. Fig. 7 is a horizontal sectional View through the power-mechanism. Fig. 8 is a detail view of the'end of the plunger head. Fig.9 is a horizontal section on the line 9 9, Fig. 2. Fig. 10 is a detail View of one of the detents and yits supporting casing.

Like numeralsof reference indicate like parts in all the figures of the drawings.

The press chamber may be of any suitable construction, but is preferably constructed as follows; I employ transverse sills 1, from the two front ones of which there arise pairs of vertical standards 2, the same being connected by superimposed sills 3, through the ends of which and the sills l tiep-rodst are passed. A rear superimposed sill5 is arranged over the rear sill l and tie-rods 6 pass through the ends of the sills 1 and 5 as shown. Upon the sills l is supported the bottom 7 and the opposite side walls 8,and between the latter is located the roof 9, which is removed or cut away between the superimposed sills 3.

It will be obvious that inasmuch as the side walls are partially removed between the two arranged in these slots are opposite vertical series of tapering wedge lshaped detents. The fulcrum end of each detent 11 fis pivoted in a U-shaped casing 57 and these casings together with the detents are seated in the series of slots, the casings being maintained in the slots by means of the metal strips 57 applied to the exterior of the chamber. If at any time a detent should break it would require simply a removal of the strip 517a to permit of its withdrawal. Vertical yokes 12 are applied to the outer surfaces of the sides 8,and coiled springs 13 are interposed be tween the yokes and the free ends of the aforesaid detents, whereby they' are yieldingly pressed inward.

A pair of brackets 14 are secured to the upper side of the intermediate superimposed sill 3 and extend forward over the feed-opening in the upper side of the baling-chamber. A pivoted arm 15 is secured to the rear side of the superimposed sill between the brackets 14a and extends forward in line with the same. This arm 15 has its front end pivoted at 15a to a pair of bearing-ears 17 formed on the upper side of a tucker-bar 18 between whose upper side and the brackets 14 coiled IOO springs 19 are interposed. The er-bar has its opposite ends provided with forwardly extended bearing-ears 20, and journaled in said ears is a transversely disposed tuckerroll 21 whose axis projects beyond the bearing-ears and has its ends connected pivotally with a pair of arms or levers 22 which have their front ends pivoted at 23 to the inner sides of the side-Walls 8 of the baling-chamber such arms being located in recesses formed in the side-Walls of said baling-chamber for their reception. I thus produce a very efficient tucking device, which by reason of the presence of the roll facilitates the movements thereunder of the plunger in a manner that will be obvious, the roll and bar serving their usual functions of tucking the material. The detents at the sides of the chamber also serve their usual function and prevent a withdrawal of the material being baled by a retraction of the plunger.

24 designates the plunger head, which may be of any desired construction, and has secured to its rear side a bracket casting 60 to which is pivoted as at 25, the end of the plunger-beam 26, the same being normally withdrawn together with the head by means of a coiled spring 27 attached at one end to the plunger-beam and at the opposite end to one of 4a pair of longitudinal beams or sills 28 which are secured to the beams of the baling chamber in the usual manner. The' upper side of the plunger-head has a sheet metal plate or covering 24a, the front of which is inclined as at58 and provided with a transversely disposed angular portion 72 to facilitate`the passage of the head under the roll and prevent clogging of the hay at the roll, and which also facilitates the rebounding of the plunger. f

The outer ends of the beams or sills 28 are supported in cross-sills 29, and. arranged thereupon is a metal base-plate 30. This baseplate 30 is securely bolted to the sills 28 and 29, and has formed upon its under side a transverse rib 30a which engages with a kerf in the sills 28 and relieves the bolts from excessive strain, and also has formed upon its upper side near its front end a vertical post 31 which forms one end of a longitudinally disposed metal frame 32. rfhe post 31 is bored and receives a stud 33 which passes centrally through a flanged opening 34 formed at the center of acompoundly curved lever 35. This lever is preferably provided upon its upper side with strengthening ribs 36 and may be providedwith one or a number of compoundly curved cam-anges 37. The flanges are not regularly curvedbut at their outer ends are more abrupt than at their inner ends as shown, and are each disposed in asimilar direction. Arranged upon the lever 35 is the sweep-arm 38 to which the usual draft-appliances may be connected.

A socket 39 is fitted on the outer end ofthe plunger-beam 26, said socket being bifurcated at its extremity and having passed therethrough a vertical pin 40, the upper end of which projects above the socket and is provided With an anti-friction roller 41 arranged in the circular path traversed by the camflanges as the lever 35 moves upon its pivot 33. Between the branches of the bifurcations I pivot upon the bolt 40 a link 42, whose remaining end terminates ina transversely bored head 43 located within the frame 32 and pivoted to the latter at one side of the post 31 by a bolt 44. That end of the link 42 which is pivoted to the plunger is provided at one side with a curved wearing-shoe 46.

Securely bolted to the outer end of the frame 32 is a quadrant shaped arm 47, the same extending around to the opposite side of the plunger-beam and being supported by brackets 50 which rise from the outer sill 29 and the adjacent longitudinal sill 28. A curved spring buffer-plate 51 is secured to the outer end of this segment-shaped arm, is doubled upon itself at the inner side of the arm following substantially the curvature thereof, and terminates short of the opposite end, where it is provided with an off-set 52 arranged opposite a threaded perforation 53 formed in said arm. An adj usting-screw 54 passes through the perforation 53 and terminates at its front end in ahead 55 between which and the o-set there is arranged a coiled spring 56. The spring-plate is disposed eccentrically with relation to the pivot-bolt 44 of the link 42, and is in such position as to receive the impact of the shoe 46 when the plunger-beam rebounds. In operation the hay or other material to be baled, is fed through the feed-opening in the roof of the press into the path of the plunger-head and the team started. The sweep 38 together With the lever 35 are revolved upon the post 31 and the cam-anges on the under side of the lever 35 are successively brought into contact with the anti-friction roller 41 at the extreme end of the plungerbeam. By reason of the disposition or curvature of each of these flanges, and the relative locations of the points of pivot of the lever 35 and link 42, the plunger-beam is moved rapidly at the beginning of its stroke and gradually, but with more power, toward the end thereof, and actuates the plungerhead to carry the material back into the chamber in the usual manner. The limit of movement of the plunger-beam is of course in accordance with the length of the anges which are, as Will be obvious, successively brought into operative position in connection with the end of the beam. As soon as the anti-friction roller has traversed over one of the flanges and it reaches the end thereof, the lever 35 of course continuing its movement the plunger-beam is released from the presence of the flange and the retracing spring 27 serves to return the plunger. The fulcruin point of the lever 35, which is its post 31, and the link 42, which is its post 43 are eccentrically located with reference lOO IIO

to one another, both being in` line with the baling-chamber. The outer end 62 of the curved ange 37 iirst comes in contact with the roller 4l and the latter is by the sweep of the lever carried toward the fulcrum of said lever. Of course, the nearer it approaches the post 3l the greater the leverage which it will be seen occurs at the last part of the stroke. The sudden retraction of the plunger which is necessary in order to return the same to a position for again operating, it is desirable to absorb and thus prevent the shock of the impact of the same. For this purpose I provide the buffer-mechanism which I have described, and it will be seen that as the plunger returns the shoe 46 will come in contact with the front end of the spring-plate, and it being set eccentrically with relation to the pivot point of the link and consequently the center upon which the end of the plunger is moving will by reason .of the frictional contact between the shoe and the plate cause the momentum to be gradually overcome and the rebound thus absorbed. The spring-plate is but yieldingly supported in the path of the shoe and hence will yield so that the return of the plunger to its normal position is almost noiseless and practically but little concussion takes place.

Of course the number of cam-lianges of the lever 35 may be varied.` I have illustrated two, but one might be used, or any number,.

the lever being varied in shape to accommodate them in a manner that will be obvious.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a very simple, strong and durable press, whose plunger may be actuated a number of times to one complete circle traversed by the draft-animal; whose power is increased by reason of the disposition of the curved flanges without increasing the draft upon the horse, and at a time when it is necessary, namely, at the end of the stroke of the plunger; and wherein the shock or concussion caused bythe return of the plunger is practically and eifectually absorbed.

I do not limit my invention to the precise details of construction herein shown and described, but hold that I may vary the same to any degree and extent within the knowledge of the skilled mechanic.
