INVENTOR. BENJAMIN RMIRANT BY 1 ATTORNEY F FFl@.

BENJAMIN AMIRANT, OF CHICAGO, ILLINOIS.

rnnss,

Application filed November 22, 1915.

To all whom it may concern Be it known that I, BENJAMIN AMIRANT, a subject of the King of Italy, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Presses Adaptcd to Express Juice from Grapes, Apples,

and other Substances.

The device embodying this invention relates to that class or kind of presses in which the juice of grapes and other articles is obtained therefrom, by pressure.

I find that a great part of the juice in grapes is forced out upon moderate pressure being applied to a mass, thereof, and that greater pressure is required to extract additional juice therefrom; and I desire, in the device embodying this invention, a machine in which a quantity of grapes may be deposited, pressure may be applied thereto and a large portion of the juice therein be rapidly obtained therefrom, and thereafter additional and greater pressure may be applied and an additional quantity of the juice contained therein may be obtained.

Particular objects of the invention are to obtain means whereby, upon the change of position of a determined lever, like movement and force applied to said lever will obtain a difference in pressure on the contents of the tub of the device: to obtain a device from which the pressed contents of said tub may be readily removed: to obtain a device in which the operative pressure producing lever may be continuously moved in a determined direction to obtain a determined pressure, and continuously moved in the opposite direction to lessen said pressure; and a device in which said lever may be moved to and fro, to continuously increase or continuously lessen said pressure: to obtain a device inwhich the required changes of position'of the operative parts which determine whether greater or lesser pressure will result from a measured movement of the determined lever are readily understood, and easily made.

In reducing to practice this invention 1 have embodied the same in the device which is illustrated in the drawings accom- Specification of Letters Patent.

panying and forming a part hereof, and in which;

Figure 1, is a vertical sectional view of said device on line ll of Fig. 2, viewed in the direction indicated by the arrows. Fig. 2, is a top plan view of the device. Fig. 3, is a perspective of a movable member which is actuable by a lever. Fig. 4, is a perspective of a movable member cooperating with the member illustrated in Fig. 3, and adapted to function as a dog or pawl. Fig. 5, is a perspective of an additional movable member adapted to be actuated by a lever and cooperatively attachable to the member illustrated in Fig. 3. Fig. 6, is a perspective of a retaining member of the device. Fig. 7, is a vertical section, on line 7-7 of Fig. 3, (viewed in the direction indicated by the arrows), of the member which is illustrated in said Fig. 3, and an elevation of a rotatable nut on which said member is pivotally mounted. And Fig. 8, is a perspective of a head member provided with an abutment on which the member illustrated in Fig. 5 may be pivotally mounted.

A reference character applied to designate a given part indicates said part throughout the several figures wherever the same appears.

A is a table forming a base, and is provided with an annular runway at, spout a and legs B.

C is a vertical shaft which is screw threaded at its upper end, and is rigidly secured in table A. The manner in which said shaft C is secured, (as illustrated in Fig. 1), is by means of the hub D, key E, and nut F. Nut F fits over the lower end of said shaft D, (which is screw threaded) and by turning the said nut tightly to place the shoulder G is brought firmly against the upper face of said table A.

The tub of the device comprises the slats H, and straps I, which are turned over at their ends to obtain eyelets or apertures in which the pins j (see Fig. 2), and removable pins'J fit. Slats H are illustrated as attached to the straps I (by bolts K), to obtain a spaced relation between them, and through the space between said slats, (lettered L in Figs. 1 and 2) the juice'extracted from the contents of the tub flows into the annular groove 0; and is discharged from said groove to spout m M represents pressure board of the device and m, blocks placed thereon.

N is a head or collar which is provided with aperture n, in which shaft 0 loosely fits, with the abutment n having the hole or aperture n? therein and the annular recess N (see Fig. 8).

0 is a movable member provided with the aperture 0 (see Fig. 5), and the recess 0 at the upper end of said aperture, and with the apertures O and O Said member 0 is pivotally mounted on head or collar N, when the pin or bolt 0 is inserted in the apertures O and n with the head of said bolt in said recess 0 P is a nut, the screw threads whereof fit the screw threads on .shaft 0, so that by the turning of said nut in opposite directions it is :moved up and down on said shaft. Nut P is provided with an annular flange "P, which fits into therecess N of head or collar N, permitting. rotation of the nut without rotation of said head or collar and transmitting the upward and downward movement of said nut to said collar. Said nut P is also provided with the annular flange 29 having apertures 19*. Q is a movable member which is pro vided'with the apertures g, 9 Q2, and g (see Fig. Aperture 9 fits loosely on or over the upper end of nut P so that said member Q is pivotally mounted on said nut, while resting on flange p.

R are bolts which fit loosely in holes Q and are provided with the heads 1", to determine how far said bolts shall project beyond the lower face of said member Q; and

said projecting'lower ends of bolts R are beveled, as is well illustrated in Figs. 4 and 7. The movable member. Q being pivotally mounted-on nut P, the apertures q ,-in said member register with apertures p in flange p of said nut, and the projecting lower ends of said bolts R extend into (fitting loosely therein), said holes 9 WVhen two, (2) of said bolts R are inserted in said member Q and l l bP in th manner which is illustrated in full lines in Fig. 7 said member "and nut are tied or locked together so,that 1 pivotal movement of said member Q producescorresponding movement of said nut P- When the bolt R which is illustrated as the left hand one in Fig.7, is inserted so that the bevelededge r thereof is inthe position indicated by broken lines in said Fig.7, movement of memberQ in one direction (to the left) will producecorrespending movement in nut P, while move- 1Inentofjsai'd member Q in the opposite dimotion will simply cause said bolts R to be moved up out of apertures 10 by the slotted aperture Q2 of member Q and aperture O of member 0 register, and T (Figs. 1 and '2) is a bolt which when put into place, extends through said apertures. When bolt T is inserted in said apertures reciprocatory pivotal movement of member 0 produces reciprocatory movement of member Q, but the angle of movement of said member Q will be considerably less than the angle of movement of said member 0. On

.the removal of bolt T and the placing of the lever S and said member Q will, of course, correspond. Much less movement of the nut P is obtained by a given movement of lever S, when said lever is in aperture O of member 0, than when in aperture g of member Q, but with correspondmg gain of pressure to the pressure board M thereunder.

U is a retaining device (see Fig. 6,) which is secured to the under side of member Q by bolts 11, (Fig. 1).

To operate the device I deem it advisable to first place the bolts R in position as illustrated in Fig. 7, and lever S in aperture y to then fill the tub with the material to be subjected to pressure; then place pressure .board M, blocks on and nut P on shaft C by continuously moving lever S, in a given direction; that is, the party operating the device can walk around it, and continuously force the nut P and pressure board M downward. When the forcing of the said lever S continuously in a given direction becomes somewhat difiicult, said pins R are placed as is the right hand one of the pins illustrated in Fig. 7, and said lever is then moved to and fro. When the force required to move said lever S being in aperture q is burdensome said lever placed in aperture- .0 of member 0, pins 0 and T are dropped into their respective apertures and lever S is again moved to and fro thereby moving member Oto and fro, said member 0 actuating member Q to and fro by means of the bolt T.

I claim I In a press, provided with a stationary, vertical, screw; threaded shaft, and a pressure board, operative means to move said board comprising a head, longitudinally llO ber provided With spaced apertures adapted to register with the apertures in said flange, pivotally mounted concentric to said nut and bolts loosely mounted in said apertures, said bolts beveled on the lower ends thereof and adapted When oppositely placed, to join said movable member and said nut and when similarly placed to join said member and said nut when said member is moved in one direction.
