To aZZ whom it may concern:

Be it known that I, HENRY REISEL, acitizen of the United States, residing at Galveston, in the county of Galveston and State of Texas, have invented certain new and useful Improvements in Hydraulic Compressors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in hydraulic presses for compressing cotton; and itis designed to provide a press which shall possess the maximum strength with a minimum of weight, as is more fully hereinafter set forth.

Referring to the drawings, Figure 1 is a front elevation, partly broken away, to better show the connections between the pistons and the lower platen; Fig. 2, a side elevation with the lower platen and cylinders removed; Fig. 2 a vertical section of the upper corner of the press, and Fig. 3 a detail cross-section taken on the line 3 3 of Fig. 1.

Referring to the drawings, the numeral 1 designates the four corner columns or tension-bars, which are made of steel or forged iron and are headed at their upper and lower ends, as at a.

The numeral 2 designates two compound beams, each of which is constructed of a pair of I-beams clamped together and connecting each pair of columns. The Ibeams rest on the lower heads a of the tension-rods, and they are clamped tightly together by short horizontal bolts 1) which pass through the webs of the beams. The horizontal flanges of the I-beams abut closely together along their adjacent edges, and are notched for the passage of the tension-rods between the beams. These compound beams not only serve to connect the columns together in two pairs, but also serve as a firm support for the compound bed 3, which is superposed upon them. The bed 3 is constructed of a series of I-beams set on edge and extending longitudinally across the press and connected together by a series of horizontal bolts 0, passing through the webs of the beams and tying all the beams together, forming a very strong and light support. Between the adjacent l-beams are inserted strengthening-plates c, which extend the full length of the I-beams and are set on edge between them, the upper and lower edges of these plates coming flush with the upper and lower edges of the I-beams and abutting against their longitudinal flanges. The compound bed thus formed has its ends resting upon the beams 2 and extending in between each pair of columns. The outermost I-beams of the bed have their flanges notched for the reception of the vertical columns, and the columns are held in the notches by means of clamps d, which are curved to partly embrace the columns and are bolted rigidly to the outermost I-beams by the long bolts 0, flanges being formed on the clamps for the passage of the bolts. The pressing-cylinders e are two in number and rest upon the compound bed 3, and the vertically working pistons e, that work in these cylinders are connected to the lower platen 7 by means of vertical bolts f, whose lower ends are hooked over transverse rods extending across the hollow of the piston, and whose upper ends extend into a horizontal opening in the platen and are provided with suitable nuts to tighten up the parts. Between the upper ends of the pistons and the platen are inserted removable distance-pieces of the usual construction. The platen is guided vertically and prevented from tilting in any direction when an uneven bale is compressed by means of guides h, which are bolted to the ends of the platen and embrace the inner faces of the tension-rods, thus guiding the lower platen in its vertical movements insures each piston being kept in perfect alignment with its cylinder, whereby the pistons and cylinders will be prevented from wearing unevenly and the packings prevented from being injured.

Mounted upon the bed 3 between the cylinders is a cylinder 6, in which works telescopically a piston or post 2', which depends from the platen. The object of this post and cylinder is to provide a support and swivel for the lower platen when it is desired to remove the pistons or rams from their cylinders for the purposes of repair and for the renewal of the packings.

To remove the pistonsit is simply necessary to first force them up to near the tops of their cylinders and. then clamp the parts in their raised positions by means of a clamp '11, surrounding the post 2' and resting on the upper ICO end of the cylinder 6. Then by disconnecting the bolts f and removing the guides 71. the platen is free to swing around horizontally upon the post i as a central pivot. The distance-pieces may then be removed and the pistons be lifted out of the cylinders in the usual manner.

The two rods at each side of the press are connected at their upper ends by the compound beams 5, which abut against the upper heads a, and are constructed in the same manner as the lower beams 2. Confined between the compound beams 5 and nuts j, screwed on a slight enlargement of the tension-rods, is the upper platen 4, which is constructed of I-beams 7c and interposed plates 7c in the same manner as the compoundbed 3, the plates and I-beams of the platen being connected together by the long horizontal bolts k The tension-rods rest in notches formed in the outermost I-beams and are clamped against the same by means of corner clamps constructed similarly to thelower clamps d.

The transverse bars Z of the platens are removably secured by bolts or otherwise to plates Z, which are bolted to the respective platens, whereby repairs may be readily made and the bars renewed individually with the least amount of trouble. These removable platen bars and plates also enable bars of different sizes and lengths to be used on the same press, since the bars are removable at will.

A hydraulic press thus constructed will be suliiciently strong to impart the heavy pressure required to compress cotton-bales to the standard density, and at the same time possess but half the weight of the heavy compressors now in use for compressing cotton. This great strength and lightness is obtained by using the compound beams and beds and platen and constructing them substantially in the manner shown and described, whereby the use of the heavy iron and steel castings heretofore employed in hydraulic cotton-compressors is avoided.

Instead of employing the clamp 2" for supporting the platen in its raised position on the swivel-post i, it is evident that any other suitable means may be used for that purpose. For instance, the cylinder 6 may be filled with water through a pipe m, connected to it at its lower end, and the water confined in the cylinder be made to serve as a support for the post i. 7

Having thus fully described my invention, what I claim is 1. In a hydraulic compressor, the combination of two platens, pistons connected to the lower platen, cylinders for said pistons, a support for said cylinders, and a swivel or pivotal support for the lower platen whereby it may be swung around horizontally away from over the cylinders, substantially as described.

2. In a hydraulic compressor, the combination of connecting rods, platens, a bed or cylinder support, cylinders mounted thereon, pistons working in the cylinders and depending from the lower platen, a telescopic swivel connection between the platen and the bed intermediate the cylinders, whereby the lower platen may be supported in its raised position and swung around horizontally for the purpose described, substantially as set forth.

3. In a hydraulic compressor, the combination of the vertical corner rods, the compound beams 2 and 5 connecting said rods at their upper and their lower ends, each of said compound beams consisting of a pair of I-beams notched to embrace the rods and connected together by a transverse bolt, a bed or cylinder support 3 resting upon the lower beams 2 and consisting of a series of I-beams set on edge and connected rigidly together by horizontal bolts extending through them, clamps (Z embracing the corner rods and bolted to the sides of said bed, cylinders resting on the bed, pistons working in the cylinders and supporting a lower platen, and an upper platen consisting of I beams set on edge side by side and bolted rigidly together by horizontal bolts extending through them, and corner clamps 70 embracing the corner rods and bolted to said platen, substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.
