HAY-PRESS- Specification of Letters Patent.

Patented Oct. 2 1, 1905.

Application filed September 14, 1904:. Serial No. 224,437.

tion is to provide an improved form of press operated by horse-power, in which positive operating means are provided for advancing and retracting the plunger twice for each complete revolution of the sweep of the horse.

proved tucker, by means of which the charges of hay or other material may be smoothly folded within the compression-chamber.

Another object of the invention is to provide improved means for regulating the size of the opening at the discharge end of the cornpression-chamber, so that the degree of compression may be varied at will, both dimensions of the opening at the discharge end of the compression-chamber varying simultaneously.

1n the attainment of the objects above mentioned I make use of the novel construction and combination of parts of a baling-press hereinafter fully described, shown in the accompanying drawings, and having the novel features thereof specifically pointed out in the appended claims, it being understood that changes'in the form, proportions, and exact mode of assemblage of the elements exhibited may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

.1 n the accompanying drawings, Figure 1 is a side elevation of the press with the sweep of the horsepower broken off to save space. Fig. is a plan view of the structure shown in Fig. 1. Fig. 3 is an end elevation of the press, taken from the left of Fig. 1. Fig. 4c is a detailed view in perspective of the preferred form of plunger. Fig. 5 is a view showing the operation of the mechanism by which the movement of the pitman is imparted to the plunger. Fig. 6 is a detail view of the mechanism operated by the sweep, the parts being shown in the position occupied at the end of the compressing movement of the pitman. Fig. 7 is a detail plan view of another device for guiding the pitman. Fig. 8 is a crosssectional view on-the line 8 8 of Fig. 7.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference, B designates the bed of the press, which consists of longitudinal timbers 1 1 and transverse pieces 2, 3, and 4, by means of which the longitudinal timbers are securely connected. At the forward end of the bed B a plate 5 is bolted or otherwise secured upon the timbers 1 1, and upon the plate 5 is rigidly mounted a hub 6, in which a pivot-pin 7, formed on the under side of a casting 8, rotates. The casting 8 supports the sweep 9 of the horsepower, which is bolted on the top of the casting, and is disposed at right angles to the casting, as best seen in Fig. 2. The casting 8 forms a rotary cross head, by means of which motion is imparted to the levers presently to be described, which operate the pitman through which motion imparted to the plunger of the press. To hold the casting 8 and sweep 9 in proper relative position, a stay-rod 10 is fastened at one end to the casting. as shown in Fig. 2, and at the other end is attached to the sweep at a point near the free end thereof, the connection of the stay-rod with the sweep not being shown.

The hub 6 on the plate 5 has formed thereon a projection 11, which is directed forward, as shown in Fig. 1, and in the end of the projection 11 is secured a steel pin 12, which extends downward through a pivoted lever-arm 13 and enters the plate 5. The lever-arm 13 is pivotally connected at its free end with a connecting rod or link 14, which is pivotally connected at the other end to the pitman 15, by means of which the plunger of the press is operated. The lever-arm 13 may be straight or may be formed on a compound curve, as shown in Fig. 1; but in either case a rib 16 is provided on the upper surface of the leverarm for engagement with steel rollers 17, rotatably mounted upon cottered pins 18, mounted in the ends of the casting 8.

At one side of the plate 5 a lateral projection 20 is formed and the steel pin 21 is cast on the projection to form a pivot for the lever-arm 22, which is provided on its upper surface with a curved rib 23 for engagement with the rollers 17 above mentioned. The lever-arms 13 and 22 are connected by means of a link 24, secured by pivot-pins in the ends of the lever-arms.

When the sweep 9 revolves in the direction indicated by the arrow as, one of the rollers 17 will engage with the rib 16 on the leverarm 13 and swing the lever to the position indicated in Fig. 6, at which point the roller 17 will pass over the end of the rib 16 and the motion of the lever-arm in that direction will cease. Immediately after the cessation of movement of the arm 13 the other roller 17 will come into contact with the rib 23 on the lever-arm 22, which is then in the position shown in Fig. 6. The movement of the sweep after the roller 17 engages the rib 23 will force the arm 22 back to its solid-line position, and as the arms 13 and 22 are connected by means of the link 24: the arm 13 will also be restored to its solid-line position. By the time the arms 22 and 13 have reached their original position the roller 17 will pass out of engagement with the rib 23 and soon afterward will contact with the rib 16 and cause a repetition of the operations just described. It will thus be seen that a half-revolution of the sweep 9 will cause the arms 13 and 22 to move from their position in Fig. 2 to the position in Fig. 6 and then to return to the original position. As the arm 13 is connected, by means of the connecting-bar 14, with the plunger-operating pitman 15, each complete swing of the arm 13 will cause a complete reciprocation of the pitman.

The pitman consists, preferably,'of an iron pipe 25, provided at the ends with slotted heads 26 and 27, the former of which projects above the plane of the upper surface of the bed B of the press. Throughout the greater portion of its length the pitman is covered by a shield or cover 28, placed on top of the longitudinal timbers 1 1, and in order to prevent the strain imposed upon the pitman by the connecting-bar 1 1 from drawing it into contact with one of the timbers 1 an arm 29 is pivotally mounted at one end of the transverse bar 4 and pivotally connected at its other end with the pitman-head 26. The arm 29 causes the head 26 of the pitman to move in an arc whose radius is equal to the distance between the pivots in the ends of the-bar 29, and in order to afford effective support for the pitmanhead 26 the curved track 30 is provided on the bed of the press.

The structures thus described cause the pitman to move in a path sufficiently straight for all practical purposes; but if it is desired to cause the pitman to have a simple to-and-fro movement any of the ordinary means for effecting such a movement may be substituted for the pivoted arm 29.

The pitman-head 27 extends beneath the frame F of the press proper and is pivotally connected with one arm of a bell-crank lever 31, supported on a transverse shaft 32, which is mountedin the press-frame. The other arm of the bell-crank 31 is disposed at an angle of about one hundred and twenty degrees to the arm connected with the pitman and is pivotally connected with two stout connecting bars 33, the other ends of which are mounted on a pin 34, connecting the members 35 and 36 of a toggle, by means of which the plunger P of the press is operated. The member 35 of the toggle is preferably composed of two bars riveted together, as shown in Fig. 2, and is pivotally connected with the plunger by means of a pin 37. The member 36 of the toggle is also composed of two bars riveted together; but at their lower ends the two bars are spread apart and are supported upon a shaft 38, secured in bearings 39 on the press-frame.

The plunger P consists, preferably, of a block 40, supported on guide members 41, a horizontal top 42, and an upright tailpiece 14:, mounted on the top 42 and suitably braced. The toggle member 35 is connected directly to the block 10 and the top 42. The top 42 and the tailpiece M are slotted, as best seen in Fig. 4:, to permit the free movement of the toggle in reciprocating the plunger. The plunger operates in a charging-chamber C and is provided at the sides of the block with notches 45 for the passage of the springretainers, by means of which the charges forced forward by the plunger are prevented from returning into the charging -chamber. The springretainers consist, preferably, of flat springs 46, provided at their free ends with triangular pieces of cast iron 46, which project into the charging-chamber. At the end of the charging-chamber and just above the spring-retainers is mounted a tucker, which consists of a metal bar 47, preferably of quarter-round crosssection, which is supported by pivoted arms 18 and is normally depressed by coiled springs 49 engaging projections 50 on the upper surface of the bar 47. The springs 19 are held in place by brackets 51, supported upon one of the cross-timbers of the press-frame at the end of the chargingchamber.

Just behind the chargingchamber is the compression-chamber C, which consists in the preferred form of upper and lower sections 52 and 53, respectively, and has at its discharge end means for drawing the upper and lower sections together to vary the degree of compression of the material upon which the press operates.

The compression-regulating devices at the end of the chamber C consist, preferably, of upper links 5&, provided on either side of the compression-chamber, lower links 55, levers 56, having cams 57 at their inner ends, pressure-plates 58, with which said cams engage,

and means for securing the levers in adjusted position. The levers 56 are pivotally connected with links 54 and 55, as shown in Fig. 3, and the cams at the ends of the levers engage with suitably-formed surfaces on the exterior of the plates 58, which are supported by links 59, attached to the upper and lower sections of the compression-chamber. Each of the levers 56 is preferably provided at its outer end with an eye 60 for the reception of a rod by means of which the length of the lever may be increased and greater power obtained.

The fastening devices employed to secure the levers in adjusted position consist, preferably, of keepers 61, attached to the bottom of the compression-chamber,and arms 62, pivoted to the levers 56 and provided at their lower ends with a plurality of openings for engagement with the keepers 61.

From the foregoing description and an inspection of Fig. 4 it will be seen that when the levers 56 are depressed the links 54 and 55 will both be subjected to strain and the upper and lower sections of the compressionchamber drawn together. At the same time the action of the cams at the ends of the levers upon the plates 58 will force them inward, and the discharge-opening at the end of the compression-chamber will be reduced in height and width simultaneously.

The general operation of the press is similar to other pitman-operated presses, the material to be compressed being fed into the charging-ehamber in any preferred manner and being forced forward by the plunger P, a-single charge being forced into the compression-chamber at each reciprocation of the plunger. The travel of the plunger is indicated in Fig. 1, in which the plunger is in the retracted position, and in Fig. 5 in the advanced position, each advance of the plunger being produced by the extension of the toggle when the bell-crank lever 31 is rocked upon its shaft 32 by the rearward movement of the pitman 15.

Any preferred method of securing the ma:

terials compressed by the press to form bales may be employed, and as the completion of the bales forms no part of the present invention the method of doing so need not be described.

To insure a reciprocating movement of the pitman in an absolutely straight direction, 1 have provided means, as indicated in Figs. 7 and 8, wherein is shown a grooved guideroller 63, which is mounted within a fork 64, carried by and projected in front of the pitman, the roller being mounted to rotate upon a vertical axis 65, which projects above the fork and has the rear end of the connecting rod or link 14 connected to the upper end thereof. This guide-roller 63 works between and engages a guideway or tracks formed by blocks 66, secured to the inner faces of the respective sills 1 by suitable fastenings 67, preferably bolts. By this arrangement the roller 63 of course travels in a straight direction in the guideway or between the two tracks 66, thereby compelling the pitman 25 to also opcrate in a straight direction without lateral swing.
