BALING MLACHINE.

Application filed January 16, 1923. Serial No. 612,998.

To all whom 2'15 may concern:

Be it known that I, KARL O. NELSON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Baling Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to baling presses and is in general an improvement of my former invent-ion disclosed in Patent Number 1,372,898, of March 29, 1921.

In baling presses of the type disclosed in the above noted patent, a movable press box is provided which is lowered after compression to expose the pressed bale. It is found that with baling presses of this gen eral type considerable head room is required as the press box must be sufficiently elevated to allow space below into which it may be lowered.

This invention is designed to overcome the above noted defect, and it has, there-- fore, for its primary object the provision of a baling press of the sliding press box type in which a minimum of head room is required.

More specifically, an object of this invention is the provision of a press of the above type with a telescopic press box.

Further objects are to provide a simple and compact means for manipulating the i press box, to provide a more compact arrangement of press, and to generally improve and simplify the construction of baling presses.

An embodiment of the invention is shown in the accompanying drawing, in which z Figure 1 is a side elevation 01' the press with part-s broken away to more clearly show the interior construction, the press box being in its retracted, or telescope d position.

Figure 2 is a side elevation showing the press box in section and in its extended po sition.

Figure 3 is an end elevation of the press with the parts in the position they occupy in Figure 2.

The press is usually mounted upon a concrete base 1 and comprises a pair of transverse I-beams 2, which may, if desired, be supported upon crosschannel arms 3 to which are secured the tie-rods 1. These tie-rods extend upwardly and are secured to a plurality of transverse channel irons 5, which may, if desired, be arranged in pairs in a manner similar to the channel irons 3 of the base. These upper channel irons carry a U-shaped track 6 with which the roller 7 of a truck cooperate. The upper platen 8 is mounted upon the truck and carried thereby and is adapted to be slid sidewise, if desired, to permit the press to be filled from the hopper 9. During compression the platen 8 is adapted to bear against the Ushaped track 6. Other modes of feeding the press may be employed, it desired, and the movable platen 8 may be replaced by a stationary platen, if found expedient. The lower or movable platen 10 is carried by a plunger 11 which cooperates with the cylinder 12 to elevate such movable platen. The platens, of course, may be provided with transverse slots or grooves to receive the baling wire or straps in the usual manner.

The control for the plunger is secured by means of a valve 18 operated in any desired manner, as by the manually movable lever 14. This valve is adapted to connect the pressure supply pipe 15 with the inlet pipe 16 or" the press, or to connect such inlet with the exhaust pipe 17. The details of the valve form no portion of the invention and may be of the type disclosed in my above noted patent.

The press box comprises a stationary lower member 18 and an upper movable member 19, which is telescopically associated with the member 18 and is adapted in one position to extend upwardly to adjacent the upper platen, as shown in Figures 2 and 3, and in its other extreme or attracted position to be positioned below the elevated movable platen 11, as shown in Figure 1, to expose the compressed bale 20.

The movable portion 19 oi the press box is provided with a rectangular bracket or.

guide 21 adjacent the upper portion and a practically similar guide 22 adjacent its lower portion. These brackets or guides are provided with apertured ears or lugs 28 and 241, respectively, which slide upon the tierods 4t and accurately guide the member 19 of the press box. Upper guide or bracket 21 is provided at its ends with lugs 25, within which are secured piston rods 26. These piston rods carry at their lower ends pistons 27 which cooperate with the relatively small, vertical cylinders 28. These cylin ders are mounted upon the base, preferably upon the I-beams 2, and may, if desired, be provided with enlarged lower portions 29, which may be readily secured to such I- beams. The upper and lower portions of the cylinders are provided with pipes 30 and 31, respectively, which pipes lead to simultaneously controlled valves'32.

Supply pipes 33 for the fluid under pres sure are provided and communicate with the valves 32. These valves may be provided with rock arms 34 connected by a. link 85, which, in turn, may be operated by a manually movable lever 36. The details of the valves 32 form no part of this invention and may be of the same type as those disclosed in my above noted patent.

The operation of the press is as follows The movable platen 11 is positioned at its lowest point, as illustrated in Figures 2 and 3, and the movable portion 19 of the press box is elevated, as shown in Figures 2 and 3. Thereafter this elongated press box is filled in any suitable manner, as by shifting the upper platen and supplying it with material by means of the hopper 9, or in fact in any desired manner. After the press box has been filled, the platen ll rises and compresses the bale to the desired extent. Thereafter the valves 32 are manipulated to lower the movable portion 19 of the press box and expose the bale.

It will be seen from the detailed disclo-.

sure that the usual head room required for this type of press has been materially reduced and the presses may now be mounted in buildings of a lesser height than formerly required. This is an extremely desirable feature inbaling presses and is secured at no sacrifice to the efficiency of the press, but is secured by an improved type of press.

' It will further be seen that the tie-rods and the piston rods 26 and cylinders 28 are arranged closely adjacent the press box and an extremely compact structure results.

It will further be seen that by the peculiar construction of press the stresses are'borne by properly positioned and designed parts and no distorting or straining action occurs, either in the operation of the compressing members proper, or in the operation of the telescopic press box.

I claim 1. A baling press comprising a frame having a base and an upper portion and tie rods joining said portions, an upper platen associated with said upper portion, a lower movable platen, means associated with the lower portion of said frame for operating said lower platen, a press box having a lower stationary portion cooperating with said lower platen and having an upper movable portion adapted to telescope the lower portion and cooperation with said upper platen, and means carried by said base for shifting the upper movable portion of said press box.

2. A baling press comprising a frame having an upper portion, a base portion, and tie rods joining said portions; an upper platen carried by said upper portion; a lower movable platen; means for moving said lower platen towards said upper platen; a telescopic press box having a lower stationary portion secured to the lower portion of said frame and an upper movable portion adapted to telescope said lower portion. and having guides adjacent its upper and lower portion slidably engaging said tie-rods; and fluid pressure means including cylinders secured to said base and cooperating pistons operatively secured to the upper of said guides upon opposite sides of said press box, for moving the upper portion of said press box.

3. A baling press comprising an upper laterally'movable platen, a lower vertically movable platen, power operated means for moving said lower platen upwardly, a press box having a stationary member adjacent its lower portion, and a movable telescopically related member normally adjacent its upper portion, and power operated means for controlling the position of said upper member, said last mentioned power operated means being independent of said first mentioned power operated means.

4. A baling press comprising a frame including an upper portion, a base, and tie rods joining said upperportion and base; an upper laterally movable platen; alower vertically movable platen; means operated by fluid pressure for moving said lower platen towards said upper platen; a press box having telescopic portions, one of said portions being movable and adapted to slide downwardly to expose a pressed bale; and means secured to said base and operated by fluid pressure for sliding the movable portionof said press box upwardly and downwardly.

In testimony that I claim the foregoing I have heretmto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin. I
