HOUSEHOLD PRESS FOR FRUITS AND VEGETABLES Filed Feb. 6, 1955 2 Sheets-Sheet 2 Patented Nov. 26, 1935 HOUSEHOLD PRESS Eon FRUITS AND VEGETABLES William Frank Kammer, .Wenatchee, Wash. Application February 6, 1935, Serial No. 5,289

11 Claims. (Cl. 100-50) This invention relates to presses for expressing the juices of fruits, vegetables and the like and the structure to be described is an improvement upon the structure shown-in my Patent No. 1,939,556, granted on December 12th, 1933.

The object of the present invention is to provide a structure operated on the same general principles as the structure disclosed in my patent but having certain improved functions thereover.

A further object is to provide a structure of this character wherein the press head is'fixed and the cup moves upward against the press head to extract the juices from the vegetable or fruit, the press head being so constructed and so related in diameter to the .cup that the discharge of the juices from the fruitor vegetable and from the cup will not be impeded by either the press head or the crushed fruit.

A further object is to provide a structure: of

this character wherein the cup is provided with a hollow handle, one portion of which constitutes a discharge duct, the bottom of the cup being so formed as to provide a runway for the juices, this runway being inclined .downward toward the discharge duct.

A further object is to provide in a structure of this character, a fixed press head supported upon a column, a cup movable upward against the press head to crush the fruit and press the juices therefrom and a receptacle support moving upward with the cup so as to maintain a constant relation to the discharged duct of the cup.

Another object is to provide improved means whereby hydraulic pressure may be used for forcing the cup upward against the press head or retracting the cup or whereby the hydraulic pressure used may be gauged.

Other objects will appear in the course of the following description. i

My invention is illustrated in the accompanying drawings, wherein:----

Figure '1 is a side elevation of a fruit and vegetable press constructed in accordance with of Fi 3.

Referring to these drawings, l designates a base forming the bottom wall of a vertically extending cylinder ll, ;the top wall of which is 2!, carried upon a cup 22. 20f 'sheet metal.

designated l2. Extending upward from the base is a column l3 which, at'its upper end, is extended laterally and over the chamber II and carries a press head, designated generally M.

The upper wall I2 of the chamber II is formed with a packing gland l5 of any suitable construction and extending upward through this packing gland is a piston rod I6, which at its lower end, carries the piston head H. The circumference of this head is grooved to receive piston rings I 8, these piston rings being of the character of: those used on automobile pistons.

Detachably'engaged with the upper end of threaded engagement with the upper end of the piston rod l6. The-central portion of this head is provided with; a recess 20, adapted to interlock with a downwardly projecting flanged stud This cup 22 is made The bottom of the cup is formedwith a central slightly depressed orconcave portion 23, adapted toform a seat for the fruit or other articles to be pressed. From this central seatj23, the bottom of the cup extends 25 downward and radially outward at 24 and the marginal-portion of the bottomadjacent the peripheral wall of the cup is formed with an annular depression 25, which extends entirely around the cup. At one point of its side wall, the cup, is provided with'the handle 26. This j handle being open at its center, as at 21, and the lower wall of this handle is formed to provide a tothe contour of the bottom of the cup 22 so 40 as to provide a full support for this cupthroughout the entire area of the bottom. The stud 2! may be disengaged from the recess 20 by a predetermined rotation of the cup relative to the head l9, or, in other words, there is in effect a bayonet joint engagement between the cup and the head.

Attached to the head by any suitablemeans is a downwardly extending skirt 29. It extends down around the body of the chamber ll. Immediately beneath the handle 26 of the cup, however, thisskirt extends outward instead of downward and is formed with the depressed portion 3E1 having a discharge pipe 3| extending downward from this depressed portion.

The wall of the chamber is also formed with an outwardly extending portion 32 which is depressed to conform to the depression 30 and receive this depressed portion of the skirt and through this depressed or convex wall 32 of the chamber, the discharge pipe 3| passes. This discharge pipe 3| telescopes into a discharge pipe 33, which extends below the pipe 3|. Exteriorly of the depression 30, the skirt 29 is downwardly extended, as at 34.

Extending across the depression 30 is perforated supporting plate 35 upon which the receptacle 36 is adapted to rest. The perforations in the plate 35 are to permit any juices which might escape from the receptacle to drain downward through the pipes 3| and 33.

With this construction, when the piston I! is moved upward and the head |9 moved upward together with the cup 22, the receptacle support 3% will also be moved upward and the pipe 3| will shift through the outer pipe 33. As the piston l1 and head l9 are moved downward, of course the receptacle support formed with the parts 3!! and 35 will also move downward.

The press head I 4 is solid and has its lower surface made to conform to the conformation of the bottom of the cup 22. Thus, the central portion of the press head l4 has a convex face 31 and from this central portion, the lower face of the press head |4 extends downward and outward, as at 38. It will be noted that the press head has a diameter substantially less than the interior diameter of the cup 22 so that when the cup is brought upward against the press head, the fruit Will not be so compressed as to be forced outward over the channel 25 and thus obstruct this channel but the fruit will be pressed downward against the bottom of the cup and all of the juices expressed therefrom.

Preferably the column I3 is provided with a duct 39 which extends from the lower end of the column and opens at its lower end into the chamber H, the duct extending upward through the column l3 and to a gauge 40, preferably disposed in a recess in the angularly extended end of the column just above the press head l4. This is a pressure gauge and may be of any suitable character.

For the purpose of discharging liquid under pressure into the space above the piston IT, to force the piston I! downward or into the space below the piston, to force the piston upward, I provide the four-way valve casing designated 4|, and having a pipe extending therefrom designated 42, which extends up through a. pushing 43, carried by the piston IT. This four-way valve 4| has an inlet pipe 44 and an outlet pipe 45, these pipes extending through the base I0 and the valve casing 4| is also provided with an outlet 46 into the space below the piston Thus when the valve is turned in one position, water entering through the pipe 44 will be discharged into the space below the piston and cause the lifting of the piston, while water which may be above the piston will be forced out through the pipe 42 and the outlet pipe 45. This will raise the piston to carry the cup upward to bring the fruit into engagement with the press head I4. After the fruit has been squeezed between the press head and the bottom .of the cup, the piston I7 is to be moved downward and to this end the valve 41 within the valve body is turned so that water from the pipe 44 will pass upward through the pipe 42 and water within the space below the piston will be discharged through the openand the column 3. A convenient material for this purpose is cast iron.

While I have illustrated certain details of construction and certain arrangements of parts, I

do not wish to be limited to these details as the invention might be embodied in a number of different forms without departing from the spirit of the invention, as defined in the appended claims.

One of the chief advantages, due to the fact that the cup moves upward against the press head, is that time can be saved in taking out the pulp and in putting in fresh fruit. Furthermore, this eliminates overhead structure and makes a better balanced press and there is no tendency to top heaviness in my present design.

While I have described my press as being particularly designed for a press for vegetables and fruit, that is a household press, I do not wish to be limited to this use as it is obvious that the same principle can be used in connection with a machine shop press by merely changing the contour or character of the confronting faces of the head I9 and the head l4 so that these heads will coact with each other to press the article between them.
