UNITED STATES FFiCES PATENT W'ILLIAM KRUTZSO, OF DAYTON, OHIO, ASSIGNOR TO THE BUCKEYE IRON AND BRASS WORKS, OF SAME PLACE. Y

SPECIFICATION forming part Of Letters Patent N0. 296,186, dated April 1, 1884.-,

Application filed December 3, 1883. (No model.)

To ZZ whom it may concern.:

Be it known that I, WILLIAM Knufrzscn, a citizen of the United States, residing at Dayton, in the county of' Montgomery and State of Ohio, have invented new and useful Improvements in Apparatus for Pressing Oil- Cake, of which the following is a specification.

This invention relates to apparatus for shaping and, pressing the meal of cotton and other seeds into cakes, and has for its object to provide novel means for effecting the shaping and pressing operations.

To' such end the invention consists in apress box or piate capable of sliding upon the ramblock of a ram, combined with brackets or other supports for sustaining the box or plate when slid from the ram-block for permitting the meal to be deposited on said box or plate.

The invention also consists in other features of construction and combination, all of which will be hereinafter described and claimed, referencebeing had to the accompanying drawings, in which- Figure l is a central vertical section taken from end toend of the apparatus, and illus trating my invention; Fig. 2, aplan view,showing the press box or plate withdrawn from the ram-block5 Fig. 3, an end elevation of the same; Fig. 4, a detached elevation ofthe valve mechanism for controlling the ram; Fig. 5, a sectional plan view taken on the line x :v of Fig. a; Fig. (i, a top plan view of the casing containing the valve mechanism; and Figs. 7, 8, and 9 are detail views.

Referring to the drawings, A indicates the pressframe of any suitable form, having at its angles or corners the four standards B, having nuts B", which standards and nuts support and hold the head-block G. The press-frame,

'as shown, is a casting centrally bored out to form an ordinary hydraulic cylinder, D, into which is tted the ram El, bearing at its top the ram-block M, the ends of which are procent to the ends, are secured brackets l?, the upper horizontal faces of which are so arjranged that when the ram is at the limit of its downward stroke the upper surface of the ramblock will be in the same plane as the 55 said faces of the brackets, so that the press box or plate N can be moved outward from the ram-block upon the bracket in position to receive the meal. A sheetmetal tray, ci, having a handle, f2, is made to closely fit the bot- 6o tom of the pressbox, the rim of the traybeing beveled on its inner edge, said tray being t-hus of dish form; and in the under side of the head-block C is a cavity corresponding to the dish shape of the tray, Fig. l, so that when `the ram is-raised the dished cavities will register, forming a chamber, within which the meal is shaped and pressed into a cake.

Adjacent toeach end of the press-frame, directly above the brackets P, is a stud, R, to 7o each of which is hinged an end platform, S, which are connected by a rod, T, serving as a handle by which they may be swung up and down. The distance between the two platforms is such that they will just admit the 7 5 press-box N between them, and their top surfaces, g2, are of aform similar to that of the cake to be shaped. The press-box having been withdrawn from the ram-block, to rest upon the brackets I), and the tray arranged 8o thereon, the platforms S are swung down to engage the ends of the tray and hold it in position.

The upper edges, e", of the platforms S, when the latter are in a horizontal position, forni trackways or guides continuous with the upper surface or edges oi' the longitudinal sides of thepressbox, on which trackway is adapted to slide a bottomless bo r, (see dotted lines in Fig. 3,) so that as this box is drawn 9o along the platform from endvto end the upper surfaces of the latter constitute a floor or bottom to the box which prevents the meal from falling out of the latter; but in crossing the space between the platforms the meal is de- '95 posited on the usual cloth laid on the tray e3. The bottomless box is then pushed back upon astationary track, (not necessary to show,) to be relilled, and the platforms S are swung up to the position shown by dotted lines, Fig. 3, af- 10o ter which the two ends of the cloth on the tray are brought up and folded over. the meal until they meet or overlap at the center, and the press-box N is then slid in upon the ram-block, the rising of which by hydraulic or other pressure under the rain shapes and presses the meal into a cake between the head-block and the press-box. The meal having been thus shaped and pressed, the ram descends and the pressboX is withdrawn upon the brackets for a repetition of thel operation.

It will be seen that the longitudinal edge of each platform S is beveled at g3, to make its upper surface conform in outline to the shape of the cake to be formed, as before alluded to, andthe lower edges ofthe bottomless box mentioned conform also to this shape in such manner thatlthe top of the meal deposited in the press-box has imparted to it the outline of the completed cake, which is effected by the sliding movement of the bottomless box over the platforms and the press-box.

I will now proceed to describe the valve mechanism by which the ram is controlled.

At one side of the press-frame is arranged a stand, M, in the base of which the valve mechanism is located, being operated by a crank, K, and shaft U through bevel-gears l and 2. The inlet a is to be connected with a pump or accumulator, and the passage b leads to the cylinder D, c being the outlet or discharge. The two valves EE slide back and forth in their respective compartments in the valve-chamber b', and are held to their Valveseats by spiral springs, and the valve-chamber is provided with passages (j, to permit the fluidpressure to reach the top of the valve and hold it tightly to its seat,which passages may, however, be in the valve itself, instead of in the valve-chamber.

To the lower end of a vertical shaft, NV, is keyed a cam, G, and to supports L L are pivi oted at f f two curved levers, H II', provided at their upper free ends with friction-rollers 1' r, which roll upon the irregular upper surface of the cam G, while the lower free ends of the said levers bear against the outer ends of sliding pins p p', which, at their inner ends, bear against the valves E E', said pins passing through suitable stuffing-boxes. The upper end ofthe shaft W connects by the bevelgears I 2 with the crank-shaft U, and the bevel-gear 2 on the shaft U is provided with just half the number of teeth as the bevel-gear 1 on the shaft fvT, so that one revolution of the crank-shaft will cause the cam G to perform one-half of a revolution. Vhcn the raised or irregular part of this cam is between the rollers o" i", both of the valves E E will be upon their respective seats, and when the raised part of the cam acts on the roller r, the lever II is tilted, thus pressing in Ithe pin p and moving the valve E from its seat, so that the fluid from the pump or accumulator entering the inlet a flows through the passage b to the cylinder at a point beneath the ram to elevate the latter. If, now, the crank-shaft be once revolved, the raised part of the cam will leave the roller r and act on the roller r', thus closing the supply-port in the valve-chamber, and by the tilting ofthe lever H opening the discharge-port c, thereby permitting the ram to descend.

A receiver, D', in the form of a saucer is arranged under the valve-chamber at the base of the stand M2, to catch such liquid as may perhaps escape through the stuffing-boxes of the valve-stems p p.

It is believed that from the foregoing the 'operation of all the parts will be clearly understood, and it may also be said that'the details in the construction of the various parts may be modified without changing the spirit of the invention.

The ram may be operated by water, oil, steam, gas, or other fluid, as desired.

Having thus described my invention, what I claim isl. In an apparatus for pressing oil-cake, a press box or plate capable of sliding upon the ram-block and brackets attached to the frame, substantially as described.

2. In an apparatus for pressing oil-cake, the combination, with a press box or plate capable of sliding upon the ram-block and upon brackets forming a support continuons therewith, of end platforms for engaging with said box or plate, and having their upper surfaces formed to approximate the shape of the upper half of the pressed cake, substantially as described.

v 3. The combination, with the press box or plate capable/of sliding from the ram-block upon brackets outside the press, of end platforms for engaging the ends of said box orv plate, and having their upper surfaces approximating the form of the pressed cake, and a receptacle adapted to traverse said platforms and press box or plate, to deposit the meal upon the latter and shape the upper portion of the mass for the press, substantially as described.

I. The method herein described of pressing oil-cake, said method consisting in laying a cloth upon a press box or plate, depositing the meal thereon, forming the mass into a shape approximating that imparted by the press, folding the two ends of said cloth over thereupon, and submitting the whole to the a'ction of the press, substantially as described.
