BALING-PRESS.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed May 18. 1907- Serial No. 374.387.

To all whom it may concern:

Be it known that I, Lnwrs P. AGNnw, a citizen of the United States of America, residing at Wapanucka, District 23, Oklahoma, have invented new and useful Imrovements in Baling-Presses, of which the following is a specification.

returning the plungers to normal position for subsequent operation.

One object of the present invention is to provide an improved type of plunger operating mechanism of the character set forth, whereby a simple, strong and durable action is produced, and positiveness and smoothness of operation of the parts insured.

A further object is to provide a construction of press in which the parts may be readily and conveniently assembled in comp act form for transportation and conveniently set up in operative position for use.

With the above and other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a top plan view of a baling press embodying my invention as arranged for operation. Fig. 2 is a similar view with the parts compacted for storage or transportation. Fig. 3 is a side elevation of the apparatus arranged as shown in Fig. 1. Fig. 4 is a vertical longitudinal section on an enlarged scale through the center of the frame and the power mechanism. Fig. 5 is a sectional plan view on an enlarged scale of the parts disclosed on an enlarged scale Fig. 6 is a sectional plan view taken substantially on the line 66 of Fig. 4. Fig. 7 is a detail view showing the construction of the friction roller support upon one of the pitmen.

Referring to the drawing, a central main frame is provided comprising a pair of side sills or bars 1 and 2, cross connecting or tie bolts 3, front and rear cross bars 4 and 5, a diagonal center reach or bar 6, and a bolster 7, the latter being arranged at the forward portion of said frame. In addition, a yoke 0r arched bearing member 8 extends centrally and longitudinally over the frame and is fastened at its ends to the bars 4 and 5 by bolts or other equivalent fastening devices 9.

The sill or side bar 1 has a length determinate by the length of the frame, while the sill or side bar 2 is provided with a rearward extension 10 forming a supporting bar or beam, which may be of any required length. A cooperating supporting bar or beam 11 is designed to be arranged at either end of the sill or side bar 1 and to be preferably fastened thereto, to which end coupling or fish plates 12 and 13 are arranged at the front and rear ends of said sill and fastened in position thereon by bolts 14, said plates projecting beyond the ends of the sill and being apertured for the passage of bolts 15 by which the bar 11 may be secured thereto. A brace 16 is fixed at its rear end to the forward end of the sill 2 and extends diagonally in front of the frame for connection at its forward end, as by a bolt 17, with the bar 11, by which the latter may be reinforced when supported at the forward end of the frame for use in the operation of forming the bales.

The baling boxes or chambers 18 and 19 may be of any preferred construction, and are slidably mounted in any desired manner upon the respective bars 10 and 11, and are adapted to be fixed in adjusted position thereon by bolts or other suitable fastenings 20, said boxes being adjustable to regulate the stroke therein of the cooperating compressing plungers. The rear portion of the apparatus is designed to be mounted for transportation upon a wheeled truck comprising a transverse axle 21 fixed to the rearwardly extending supporting bar 10 and carrying at its ends supporting and traction wheels 22.

In the normal operation of the parts the bars 10 and 11 may be arranged to extend rearwardly and forwardly of the frame and on opposite sides of the center line, as shown in Fig. 1, in which arrangement and operation the plungers acting within said chambers are forced outwardly during the compression stroke in opposite directions, as will be readily understood. The supporting bar 11 is, through the construction described, capable of being removed from the front of the frame and applied at the rear to extend parallel with the bar 10, so that the compression chambers will lie alongside one another, as will be apparent by reference to Fig. 2, for carrying out the baling operation 1'5 ratus when so assembled for storage or transin confined spaces or permitting the apparatus to be arranged in compact form for storage and transportation. the front supporting bar and box 19, it wil be understood that the bolts 15 connecting said bar with the blade 12 and the bolt 17 connecting the bar with the brace 16 are removed, the bar disposed at the rear of the frame, as indicated in Fig. 2, and the bolts 15 applied to couple said bar with the fish plate 13, thus arranging the bar and its box in parallel relation with the bar 10 and box 19. The bar 11 is provided with suitable means, such as a clip, for connecting it with the axle 21, by which the rear portion of the appaportation will be sup orted upon said axle and its carrying whee In this position the plungers may be operated for forming bales of hay or other materials in the baling boxes, thus enabling the apparatus to be employed for such purpose in a confined space.

The front of the apparatus is supported upon a truck comprising an axle 23 ivotally connected with the ,bolster 7 by a ing bolt 24, to the ends of which axle are secured the ends of a circle plate 26 extending in advance thereof and beneath the forward ends of the sills 1 and 2 and turning in contact with one or more shoes 27 fixed to the front cross bar or forward ends of the sills, as desired, thus forming a fifth wheel connection by which the apparatus may be turned or steered. Carrying and-supporting wheels 28 of any preferred construction are mounted upon the ends of the axle beyond the ends of the circle plate. On the front portion of the circle plate are brackets 29 supporting a cross bolt 30', to which the rear end of a draft tongue 31 is connected in any preferred manner, which tongue will be equipped in practice with the usual draft appliance to enable the apparatus to be drawn from meadow to meadow orplace to place by two or more draft animals.

Plungers 32 and 33 operate in the respective boxes 18 and 19, and to these plungers are pivotally connected the outer ends of pitmen or actuating rods 32 and 33, each of which is provided adjacent toits inner end with a friction roller 34, journaled upon a bracket 35 suitably secured thereto and of proper construction for the purpose.

The power mechanism for operating the plungers comprises a vertical shaft 35 ournaled at its lower end in a hollow bearing 36- carried by the diagonal bar 6, the meeting faces of the shaft and bearing being formed to provide a channel for the reception of antifriction bearing balls 37, permitting easy motionof the shaft in said bearing member. The upper end of the shaft projects above the yoke or hearing member 8 through a hollow bearing boss or hub 38 formed thereon, and to said shaft is keyed or otherwise In thus arranging one end of which is provided with a folding section 43. The section 43 is hinged or pivoted to the adj acentend of the main portion of the sweep, as at 43, to fold backward parallel therewith, as shown in Fig. 2, the meeting ends of said portions being halved or scarfed to form a lap joint and disposed in operative position and are apertured for the passage of a connecting bolt 44.

In transporting the apparatus through narrow gates or woodland roads or paths, the bolt 44 may be removed and the section 43 swung back parallel with the body of the sweep which may be extended lengthwise of the apparatus, as shown in Fig. 2, in order to render the apparatus more compact and free from projections to interfere with surround-- ing objects.

Thepower head or eccentric 40 is of triangular form and comprises a plate having a depending marginal flange 45, and a substantially triangular inner rib formed by integral plates 46 arranged approximately parallel with the sides of the flange 45 to form an intervening channel or trackway 47 receiving the friction rollers 34 of the two pitmen which are adapted to travel in said channel as the power head or eccentric rotates. The sides of the flange 45 of the triangular head acts upon the said friction rollers in, the nature of cams or eccentrics to effect the projection and admit of the retraction of the plungers. The corner angles of the flange; form seat recesses 48 in which. the rollers 34 seat at the limit of their movements and fitted upon the side walls of the flange in rear of said recesses in the direction of rotation of the head are contact shoes or blocks 49 adapted to engage .the rollers to transmit motion tothe pitmen, each of said shoes being secured at itsrear end by a bolt 49 and connected at its front end with a bolt 50. As each shoe comes in contact with the roller 34 of a pitman, the latter will be forced outwardly or forwardly to project the plunger until the latter is projected to its fullest extent, when the shoe will carry the pitmen laterally to a certain extent, a movement permitted by the pivotal connection of the pitman with the plunger until the forward end of the shoe, through the cam form of the head, passes around and forward of the roller, whereupon the latter will run back.

upon the inner face of the shoe and finally seat in the next adjacent corner recess in the direction of rotation of the eccentric, ready for the subsequent projecting operation.

Gates or guard dogs 51 are pivotally mounted between the corners of the inner track plates 46 and project inwardly and outwardly therefrom, the outer ends of said gates or dogs guarding the spaces between the respective sides of the triangular channel and the seat recesses 48, in which position they are normally maintained by springs 52 acting on their inner ends and arranged between the same and the plates 46. In the movement of either friction roller 34 from one of the sides of the channel 47 in which it is released to the adjacent seat recess 48 in the rotation of the eccentric, said roller moves in contact with the adjacent dog 51, which. yields under the resistance of its spring to permit the roller to pass and seat within the recess, the gate then returning to normal position and preventing any backward movement of the roller so that the latter will be retained in position to be engaged by the coacting shoe for the ensuing forward motion of the plunger, whereby any possibility of the rollers becoming wedged. or binding in the corners of the trackway from a rebounding action of the plungers will be effectually avoided.

In conjunction with the means for projecting the plungers automatic means for retracting the plungers is provided, said means comprising a triangular cam 53 fixed. upon the shaft 35 below the eccentric, the points of said cam being arranged to operate upon rollers 54 carried by an opposite disposed pair of levers 55 respectively pivoted at one end of the sills 1 and 2 and pivotally connected at their opposite or free ends with the respective plungers, by link rods or bars 56. Each lever is stayed or strengthened by a suitable chord or brace 57, and the lever connected with the pitman 32 is provided with a roller 58 to run upon the sill 1, while the lever connected with the pitman 33 is provided with a corresponding roller 58 to run upon the sill 2, thus permitting them to swing in the arc of a circle. The points of the cam 53 are so arranged that when the friction rollers 34 of the pitmen are released by the shoes 49, the point of the cam will come in contact with the lever of the released eccentric and swing said lever outwardly, thereby positively and automatically retracting the plunger. The pitmen are arranged to run under guide rollers 59 revolubly mounted upon the sills 1 and 2 and insure ease of operation thereof.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the apparatus will be readily understood,

and it will be seen that a construction is provided whereby the baling boxes may be arranged in parallel relation for the compressing operation or disposed to project from opposite ends of the frame, as preferred, and that provision is also made by the capability of disposing the boxes in parallel relation for arranging the parts of the apparatus in close compass for storage or transportation. It will also be seen that simple and positive means are provided for projecting and retracting the plungers and preventing any liability of the binding of the plungers on their return stroke. If necessary, the supporting wheels upon the two axles may be removed to allow the apparatus to rest firmly on the ground during the compressing action, after which, when it is desired to transport the apparatus, the latter may be jacked up and the wheels replaced. In

transporting the baling box 18 from the front to the rear of the frame, the supporting bar 11, after being fixed to the rear end of the sill 1, is clipped or otherwise fastened to the axle 21, after which the rear end of the frame may be bodily raised by means of jacks and the wheels 22 applied, so that, upon the proper arrangement of the parts of the front running gear the apparatus may be transported from one field or meadow to another or from the field to the barn for storage in a convenient manner.
