SPECIFICATION forming part of Letters Patent No. 631,447, dated August 22, 1899.

Application filed November 16, 1898. Serial No. 696,623. (No model.)

To all whom it may concern.-

Be it known that I, JEROME O. TAFT, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of presses used for compressing cotton and the like into bales or receptacles for the market. It is fully explained and illustrated in this specification and the accompanying drawings.

Figure 1 shows a vertical section of the press, taken on the line 1 1 in Fig. 3. Fig. 2 represents an elevation of the greater part of the press, showing the hydraulic compressingplunger in a raised position. Fig. 3 is a crosssection of the upper part of the press, taken on line 3 3, Fig. 1,1ooking up. Fig. 4 is a cross-section of the lower part of the press, taken on line at 4, Fig. 1. Fig. 5 represents a part of the pistonresser with its shield and a part of the sleeve on the presser-rod and a part of the guide-box. Fig. 6 is a perspective view of part of the piston of the hydraulic press and the case on it, one side of the case being open.

The object of this invention is to produce a press that will combine the rapidity of steampacking and the enormous pressure available in the hydraulic press to compress the cotton when packed, and thus combine the quickness of steam with the more powerful though slower action of the hydraulic press and accomplish what neither will do without the other.

The construction and operation of the invention is this:

In Fig. 1 is shown thewhole press as it stands occupying three stories of a warehouse. Four heavy metal upright bars C O are socured at their upper ends in a square capplate D, one at each corner of the plate, by collars on the bars on the under side and heavy screw-nuts on the top of the plate. The lower ends of the bars 0 are held in a footplate 13, which serves as the head of the cylinder H of the hydraulic press in like manpresser-head P on two opposite sides.

nor as the upper ends, only the relative positions of the collars and screw-nuts are reversed. of the hydraulic cylinder. On the top ofthe cap-plate D is erected a vertical steam-cylinder G, having a piston A of the usual form, the rod R of which extends down through the plate D, in which a stuffing-box a surrounds it, and has a plate P on its lower end that serves to pack the cotton in the case as it is fed in on the second floor F. The steamcylinder G is furnished with the usual wellknown valves that give the piston an intermittent reciprocating motion. A sleeve L surrounds the extension of the piston-rodR below the plate D and is fastened to that plate The press stands on the lower end by bolts through a flange on the upper end of the sleeve. The object of this sleeve is to transfer the pressure on the piston-plate P to the cap-plate D when the hydraulic piston is operated. The plunger J in the hydraulic cylinder H has a head K, on which is a receptacle .N, that holds the sheetmetal or wire case T, in which the cotton is packed. Above the receptacle N is an open-ended metal box 0 of the same dimensions laterally as the receptacle, but only extending from the top of the receptacle N to the top of second floor F. The box 0 has ear-guides c c on each side fitted to slide up and down on the small rods cl d, the upper ends of which are made fast to the cap-plate D. This box 0 is to conduct the cotton as it is fed in on the second floor F down into the receptacle, and

the box is carried up over the sleeve L out of p the way by the receptacle N when it is raised up by the hydraulic press. (See Fig. 2.) A plate M is attached by its lower end to (the See Fig. 5.) These plates extend some ways up and are connected together at the top for support by bars V. The plates slide up and down freely on the sleeve L as the presser rises and descends to pack the cotton, and their use is to shut up the opening on the back and front just above the second floor F and prevent any of the material from getting in above the presserhead when it is down, as shown in dotted lines in Fig. 1. The sleeve is provided with flanges e e to support the upper end of the shieldplates M.

The operation is as follows: A case T is placed in the receptacle N and the doors j j on the front and back are fastened. The cotton is then put in from the second floor F under the presser-head P and is passed down through the box 0 into the case until it is filled. Then the presser P is pushed down quickly by the steam in the cylinder G to pack the cotton X. (See dotted lines in Fig. 1.) Then the presser P is as quickly drawn up again and the case is again filled with cotton, when the presser again descends and rises, and these motions continue until the case or receptacle is full and the presser will not condense the cotton any more. Then the hydraulic press is brought into action and the receptacle is carried up with immense force over the presser-head P and the sleeve L, as in Fig. 2, and the cotton X is compressed into a comparatively small compass. Then the hydraulic press sinks down with the case in the position seen in Fig. 1, when the cotton is again filled in and the presser packs it, as before, until the case or receptacle is full. Then the action of the hydraulic press is repeated. A succession of three or four pressure packings and compressions of the hydraulic press will fill the case solid. The plunger J is then let down with the receptacle until the head K rests on the plate B. Then the head of the case is put in and pressure put on it by the presser or the hydraulic press and made fast. The doors of the receptacle are then opened and the packed material is taken out ready for storage or shipment. \Vire in the shape of netting may be used to secure the pressed material, or it may be inclosed in it either before or after it is taken from the press.

Having thus described my improvements,

I claim as my invention and desire to secure by Letters Patent-- 1. In a press for cotton or other like material, the combination of a steam-cylinder, a piston for said cylinder having a piston-rod elongated to serve as a presser, a stationary sleeve over said rod to support it and take the final pressure, a receptacle to receive the packing-case, and a hydraulic press to raise said receptacle over said piston-rod and sleeve to compress the material in said case, substantially as described.

2. In a press for cotton or other like material the combination of a steam actuated presser to pack the material in a packingcase, a receptacle to hold the cotton, an openended box held over said receptacle to conduct the material into the receptacle, and arranged to slide up over said presser out of the way of the receptacle when raised, a hydraulic press to raise said receptacle over the steampresser to compress the material, in the case, substantially as described.

3. In a press for cotton or other like material, the combination of a steam-cylinder, a piston for said cylinder having a piston-rod elongated to serve as a presser, a stationary sleeve over said piston-rod to support it and receive the final pressure, a receptacle to receive the packing-case, shield-plates secured to the side of said presser to close the feed ing-opening, and prevent the cotton or other material from getting in over the presser, substantially as described.

In testimony whereof I have hereunto set my hand this 5th day of November, A. D. 1898.

JEROME O. TAFT.
