PRESS.

SPECIFICATION forming part of Letters Patent No. 335,816, dated February 9. 1886.

Application filed May 7, 1885.

To all whom, it may concern:

Be it known that I, JUL-iUs H. HOLMGREEN, of San Antonio, in the county of Bexar and State of Texas, have invented a new and Improved Press, of which the following is a full, clear, and exact description.

The object of my invention is to facilitate the baling of cotton and other fibrous substances.

The invention consists in compressing-rollers placed in suitable bearings, so as to coincide with an inlet-channel which receives and guides the fibrous substance to be baled into the baling-box of a press after the compressing-rollers have given it a preparatory press mg.

The invention further consists in details and combinations of parts, as will hereinafter be fully described and claimed.

Figure 1 is a sectional view through the lines a: w of Fig. 2. Fig. 2 is an end View of the press, and Fig. 3 is a detail crosssectional view of the compressing-rollers.

In the drawings, A represents the balingbox of the press, which rests upon the supporting-timbers A, which are in turn supported by the ground-timbers A The upper timbers, B, which rest upon the shoulder B of the tie-bolt B are parallel with the timbers A. The tie-bolts 13* unite the upper and lower timbers, thereby making a firm and strong frame-work for holding the different parts of the press in position.

The baling-box A has its side walls hinged at their bottoms to battens a on the timbers A, to facilitate the removal of the baled material after being properly strapped. The baling-straps used for this purpose are held in the spaces intervening between the floorslats a of the box A and the slats a on the follower B. To the follower B, which works in the baling-box A, is secured, by means of the bolt 0, the piston 0, working in the hydraulic cylinder D. The cylinder has lugs e, which are secured to the cross-timbers b b by the bolts 6, thereby holding the cylinderfirmly in position. At the top of cylinder D a pressure-gage, E, is attached, and leading from the top of cylinder D to the water-tank G, which is held in position by the side projection, being secured to the timbers B, is the exhaust Serial No. $4,667. (Nomodch) pipe F, having suitable stopcock, 'H, for exhausting the water in the hydraulic cylinder D when it is desired to raise the follower B. The pipe .T, which connects the pump I with the cylinder D, has a branch pipe, j, which leads to the tank for supplying the water for operating the piston O.

The eccentric-rod i, which reciprocates the piston-rod 'i" of the pump I, through the medium of the eccentric K on the shaft L, plays horizontally in the guide i, which projects downward from the bar I)" on the timbers B. This holds the rod i against lateral movement. The forward stroke of the pump-piston draws the water from the tank G through the pipe j into the pipe J, and the return-stroke of the pump-rod closes the valve d, ope1 is valve d, and forces the water through the pipe J into the cylinder D, where it acts on the piston O, causing the follower B to descend within the baling-box A. The eccentric K on the shaft L, which reciprocates the pump-piston i", receives its motion from pinion N which is loosely mounted on the shaft 0, meshing with the gear-wheel N on the shaft L. To the outer end of the shaft 0 the driving-pulley P is se; cured, and on the shaft 0 a gear-wheel, Q, is loosely mounted,which meshes with the gearwheel g on the roller S, and the pinion s on the opposite end of roller S revolves the roller R by meshing with its pinion 1'. this train of gearing motion is communicated to the pump and compressing-rollers S and 1t, and as it is necessary to work the compressingrollers R and S first independently of the pump a double clutch, p, is feathered on the shaft 0 between the gears N and Q. The clutch p is shifted to engage with clutches formed on the opposite faces of the pinions N and Q by means of a forked lcver working in the annular groove 1).

The compressing-rollers R and S are journaled in adjustable hearings to in the boX T, which are adjusted and held down by the springs u. The side of the box T joining the feeding-apron WV is open, and on the opposite side of the box T a guiding inlet-channel, t, having its inner end beveled to fit against the rollers, is situated, the object of which is to receive the material to be baled from the preparatory rollers R and S and deliver it to the'baling-box A. It also prevents the mate rial from winding around the rollers R and S. In operating the press the pump is thrown out of action by shifting the clutch p to engage with the gear Q and to be out of engagement with the pinion N. The pinion N, by being loosely mounted on the shaft 0, receives no motion from said shaft, and consequently the pump is at rest. The gear Q being engaged with the feathered clutch pis caused to revolve, and by meshing with the pinion qthe motion is imparted to the roller S, and through pinions s and r to the roller R. The material to be baled is now fed down the apron W to the rollers R and S, between which it receives a preparatory compressing, and then is forced by the said rollers into and through the inletchannel it to the baling-box. When the desired quantity has been fed to the baling-box, the clutch p is shifted, which stops the rollers R and S and operates the pump I by the motion imparted to the eccentric K by the gears N and N. The pump I drawing water from the tank G and forcing it into the cylinderD, as before described, causes the follower B to descend withinthe baling-box A, and gives the material the final packing in the baling-box, after which the side walls are swung down and the baling-straps adjusted, when the bale is removed.

Although I have here shown a hydraulic press, it is evident that the preparatory compressing-rollers R and S may be used in connection with any form of press wit-h great advantages,as by the use of the rollers Rand S the large unwieldy press-box now in common use is discarded and a smaller and more easilyman'aged one substituted, taking up less room substantially as and for the purpose set forth.

and follower B, of the gear-wheels N N, the clutch p, the gear-wheels Q q, and the compressing-rollers R and S, substantially as herein shown and described.
