4 Claims.

My invention relates to the construction of squeezersfor grapefruit, oranges, lemons, etc. in which the fruit to be squeezed is cut and is squeezed between the cooperating dies.

The main purpose of the invention is to secure simplicity of construction, cheapness in manufacture, and quickness and ease of operation using foot power.

A further purpose is to provide a single pair of supports, which are also guides, at the outer side limits of a squ'e'ezer of the character indicated and to mount all the other parts either directly upon these guides or to slide these parts upon them.

Further purposes will appear in the specification and in the claims.

Figure 1 is a front elevation of my squeezer.

Figure 1a is a fragmentary view to reduced scale of a modification of Figure 1 showing one central spring only.

Figure 2 is a section of Figure 1 upon line 2-2.

Figure 3 is a fragmentary longitudinal section of a portion of a clamp by which the mechanism may be mounted.

In the drawing similar numerals indicate like parts.

One feature of my invention lies in the unusual simplicity by which a treadle operates a movable frame carrying an upper, outer squeezing die along a single pair of rods which act as guides, but against the-resilient resistance front tension springs which normally hold the movable frame at its maximum height.

The base 5 supports tubular standards 6 and l, which at their lower ends contain plugs 8, rigid with the standards. The plugs are shouldered at 9 and extend through openings Ill in the base, also through washers H. The nuts 12 fit upon threads l3. The tubes 6 and I are thus held within cups l4 within thebase.

The transverse brackets, l5 and I6 are permanently secured to the standards, I5 carries an upwardly convex die I! and a funnel I8, I 6 carries a cup l9.

The die is perforated at and drains into a collector 2|, which is perforated at 22 and which is held in place within the upper partof the funnel by an outer wall 23.

The upper fixed bracket with its upwardly facing male die and its funnel perform no other function than to take part in the squeezing operation and ,to direct the juices squeezed out through the funnel into the cup.

The lower bracket It. performs an additional function later described.

The upper die, funnel and cup are all removable from the brackets. The two brackets are fastened to the standards 5-! by sleeves 24 and pins 25. The uppermost and lowermost transverse bars 26 and 21 form the upper and lower parts of a movable frame, and are united to move together by side rods :28 and 29 passing through projections 3t and 3|, rigid with the bars. They are held within the projections by nuts 32 and lock nuts 33.

The bars are provided with guiding sleeves 34 which ride upon the standards 6 and 1 and guide the frame. The upper-most part 26 carries a female die 35 co-operating with male die H. The lower bar 2'5 is treadle-operated' and is retracted by springs 36 and 31, (spring 36' only in Figure 1a) which are attached to the bracket It at their upper ends and to the bar 21 at their lower ends.

The treadle mechanism includes lugs 38 to which the treadle lever 39 is pivoted by a pin 40. The treadle connects through ears 4|, pin 42 and tension rod 43 with a block 44 connected through trunnions 45 and ear 46 with the lower bar 21.

At any point along the lengths of the standards 6 and I a C clamp 4'! may be located for the purpose of attaching the entire mechanism to a shelf, table or other support, the clamps being set in their positions along the lengths of the standards by set screws, 41. Two such clamps appear t the upper ends of the standards.

Holes 48 permit the machine to be fastened to the floor.

In operation, the movable frame is normally held in its uppermost position by the tension springs, leaving an open space between the two dies, into which space a half grapefruit, lemon, orange or other citrus fruit is placed with the cut edge down. The treadle is then depressed by foot power bringing the frame down and forcing the female die over the fruit, squeezing the juice .of the fruit out through perforations 20 into the general manner.

When the fruit has been squeezed the treadle is released and the tension springs bring the parts back to the position of Figure 1 where the or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the structure shown, and I, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1,. In a squeezer for citrus fruit, vegetables, etc. a base, a pair of standards rigidly supported in the base, upper and lower fixed brackets extending across from standard to standard, a squeezing die carried by the upper bracket, a pair of movable bars sliding along the standards, one above the upper fixed bracket and the other below the lower fixed bracket, a squeezing die mounted upon the upper movable bar to cooperate with the die upon the upper fixed bracket, side rods joining the movable bars to form a frame movable as a unit, tension spring means between one of the brackets and one of the bars, and a treadle connected with the lower movable bar and adapted to pull down the frame by foot power against the spring tension and to effect the squeezing of fruit between the two dies.

2. In a squeezer for fruit, vegetables, etc. a base, a pair of standards thereon forming side supports and guides, a pair of upper and lower fixed brackets mounted upon the standards, an upwardly facing die mounted upon the upper bracket, a frame comprising transverse movable bars and side rods connected therewith, guides for the frame movable upon the standards, a second die upon the upper bar of the frame, spring tension means connecting between the lower bracket and the frame, normally holding the movable frame up and retracting it when it has been moved downwardly, a foot power lever movably connected to the base and connections between the lever and the frame whereby with downward lever movement the frame is pulled downwardly and fruit, etc. is squeezed between the dies and when the lever is released the frame is retracted to its upper position.

3; A juicer, comprising a base, standards on the base, relatively superposed frames fixed on the standards, relatively superposed frames slidably mounted on the standards and connected to each other, means resiliently maintaining one of the slidable frames in a predetermined relation to a fixed frame, expressing means including a movable part mounted on one of the slidable frames and juice-receiving means mounted on one of the fixed frames, and manually operable means associated with said one of the slidable frames for actuating the expressing means.

4. A juicer, comprising a base, standards on the base, relatively superposedframes fixed on the standards, relatively superposed frames slidably mounted on the standards and connected to each other, means resiliently maintaining one of the slidable frames in a predetermined relation to a fixed frame, expressing means including a pair of dies, one mounted on a movable frame and the other mounted on a fixed frame, juice-receiving means mounted on another one of the fixed frames, and manually operable means associated with one of the slidable frames for actuating the expressing means.
