FRED A. LUNDAI-IL, OF MOLINE, ILLINOIS.

BALING-MACHINE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed July 9, 1914. Serial No. 849,935.

T 0 all whom it may concern Be it known that I, FRED A. LUNDAHL, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Baling- Machines, of which the following is a specification.

My invention has reference to baling presses, the chief purpose thereof being to provide a machine of the class named for baling waste paper, rags, and other refuse material, which machine will be simple, efficient, and durable, and will be formed of metal throughout.

In the drawings, Figure 1 is a front elevation of my machine with the receiving door open. Fig. 2 is a side elevation thereof. Fig. 3 is a horizontal section through the rear plate of the machine. Fig. 4; is a view of the lower part of the machine with the door open.

My device embodies a receptacle formed of side plates 1 and 2, a rear plate 3, a base plate 4:, and a door 5 hingeably connected to the plate 1. All of said parts are formed of sheet metal, the plates 1 and 2 being braced at top and bottom by means of outwardly projected flanges 6 and 7, and the rear plate 3 is reinforced by ribs 8 formed vertically therein by pressing outwardly a portion of the metal of said plate. The floor 4 is given additional strength by being projected upwardly a short distance within the receptacle, and the door 5 is provided with reinforcing ribs 9, formed by bending the metal outwardly.

The door 5 is formed with a hinged upper section 10, the downward movement of which is limited by braces 11 pivotally supported in the lower part of the door. The lower part of the door is held in closed position by means of a frame 12 pivoted to the side plate 2, and held in place by a latch 13 pivoted to the door 5. Mounted on the body of the press is a cover 6 and a pair of angle bars or plates 14 between which latter are outer and inner brackets let and 14 respectively in which is rotatably supported a shaft 15, upon which is secured a pinion 16. Secured on the plates 14, which additionally constitute a top reinforcement for the press, is a guide 17, in which a rack 18 has vertical movement, the teeth of said rack being in mesh with the teeth of the pinion 16. On

the lower end of the rack 18 is secured a plunger 19, which upon the downward movement of the rack is caused to exert a pressure upon the contents of the receptacle to force the same into compact space. Fixed on the shaft 15 is a ratchet wheel 20 adapted to be engaged by a pawl 21 on the inner end of a hand lever 22, pivotally supported on said shaft. On the outer end of the shaft 15 is a hand wheel 23, by operation of which the shaft 15 may be rotated in a direction to raise the rack 18. To rotate said shaft in theopposite direction and move said rack downwardly, the pawl 21 is turned over into engagement with the wheel 20; and the lever 22 moved downwardly. lVhen the rack 18 is in elevated position, it may be held therein by means of a trip 2-1, pivoted in the guide 17, and adapted to engage the teeth of the rack. By turning said trip in the opposite direction such rack may be locked from up ward movement to hold the contents of the receptacle in compressed shape until the same have been suiliciently bound. In operation the upper part 10 of the door is dropped downwardly, and the plunger 19 raised to its highest point, (see Fig. 1), leaving an opening for the introduction of the material into the machine. lVhen the receptacle is filled to such a height as the opening will permit, the upper part of the door is closed and secured by hook 25, or other suitable means. The plunger 19 is then lowered, compressing the contents of the machine into shape for binding.

The binding operation may be accom plished by means of suitable wires or cords passed through openings 26 in the rear plate of the machine and along channels formed by plates 27 fixed to the plunger 19. The floor 4 is similarly provided with channels formed by plates 28 along which the lower ends of the wires may be passed. Previous to this operation the door 5 has been opened, and the ends of the wires may be brought to gether in front of the bundle and fastened together. The plunger 19 is then raised and. the bale removed from the machine.

To further reinforce the side plates and prevent them from bending or buckling under the strain of the compressing oper ation, I provide on the outer face of each of said plates a channel plate 29, extending from top to bottom thereof, and provided near its middle part With two or more notches 30 which permit a limited amount of contraction to the strips 29 when the machine is under pressure.

My machine being formed of metal throughout, the parts thereof being rigidily united wherever possible, and the weaker partsthereof being reinforced fully, the maximum amount of efficiency is obtained with the minimum amount of material. A machine is thereby produced which is not only of comparatively light weight, but which possesses all the necessary points which tend toward durability.

lVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is:

1. A baling press, comprising a receptacle formed of sheet metal side plates, provided at top and bottom with outwardly projecting flanges; a back plate formed of sheet metal provided with vertical reinforcing ribs integral therewith; a sheet metal door hinged to one of said side plates having transverse integral ribs, and provided with a pivoted upper section adapted to drop clownwardly; a plate mounted on said receptacle; a rack vertically movable in said plate; a plunger on the lower end of said rack; a shaft rotatably mounted on said plate; a

pinion on said shaft in mesh with said rack; a ratchet wheel on said shaft; a hand lever pivoted on said shaft and provided with a pawl adapted to engage said ratchet wheel; a hand wheel fixed on said shaft; and means for locking said rack from upward or clownward movement as desired.

2. In a device of the class named a receptacle comprisin a pair of side plates, provided at top and bottom with outwardly projecting flanges; a rear plate provided with vertical reinforcing ribs formed integrally therefrom; a door hingeably connected with one of said side plates, and provided with a pivoted upper section; transverse reinforcing ribs in said door; a frame pivotally attached at the free side of said door; a latch pivoted to said door and adapted to engage said frame; and reinforcing angle plates on the outer faces of said side plates the outwardly projecting portions of said angle-plates being provided with a plurality of notches.

In testimony whereof I ailix my sigi'iature in presence of two witnesses.
