LEMON PRESSER OR SQUEEZER.

SPECIFICATION forming part of Letters Patent No. 447,975, dated March 10, 1891.

Application filed August 13, 1890- Serial No. 361,875. (No model.)

To all whom it may concern:

Be it known that I, SALATHIEL 0. Born, a citizen of the United States, residing at Carrollton, in the county of Carroll and State of Missouri, have invented a new and useful Lemon Presser or Squeezer, of whichthe following is a specification.

This invention has relation to lemon pressers or squeezers; and the objects inview are to provide a press adapted to be operatedby foot or hand and to successively deliver, cut, and squeeze a series of lemons subjected thereto, eject the skins and pulp, strain the juice, and deliver the same into a waiting receptaele.

Various other objects of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a lemon squeezer or press constructed in accordance with my invention. Fig. 2 is avertical longitudinal section of the same. Fig. 3 is a similar view, the plunger being lowered as in the act of squeezing or pressing a lemon. Fig. 4 is a detail in perspective of the plunger and its rod. Fig. 5 is a detail in perspective of the reciprocating bucket. Fig. 6 is a similar view of the combined strainer and knife.

Like numerals indicate like parts in all the figures of the drawings.

1 designates a standard mounted upon a suitable base 2. Secured to the front face of the standard at a suitable height thereon isa bracket 3, having a circular opening extending vertically through the same and terminating in the lower end of its opening in a discharge-spout 4. The opposite sides of the bracket are grooved vertically, as at 5, and secured to the same arethe lower ends of a pair of opposite verticalguide-rods 6, the upper ends ofnvhich terminate in a block 7, secured to the front face and near the upper end of the standard.

8 designates a small bracket located under the discharge-spout 4 and adapted to receive a glass, bucket, or other vessel for the purpose of holding the juice as extracted.

9 designates a strainer, cup, or disk having an annular recess upon its under side, so as to fit within the opening of the bracket 3.

The upper face of the strainer is dished or concaved, as shown, and minutely perforated and provided with an upwardly-disposed knife or blade 10. The opposite edges of the strainer have grooves 11, which register with the grooves 5 of the bracket and form a continuation of the same. Set in a recess 12, formed in the front face of the standard 1, immediately above the strainer, is a spring ejecting-tongue 13, the lower end of which curves outward and terminates above the strainer.

14 designates a sliding bucket centrally bored throughout its vertical length and having grooves 15, whereby it is adapted to receive and slide vertically between the opposite guide-rods G. The bottom of the bucket 14 is provided with an annular flange 16, which fits within the concaved upper face of the strainer 9, and said bucket rests upon the strainer when in its normal position.

17 designates a yoke, the opposite ends of which are provided with recesses or grooves to receive the opposite guides 6. From the upper end of the yoke extends a plunger-rod 18, the upper end of which reciprocates through an opening 19, formed in the block 7. From the under side of the yoke depends a head 20, cylindrical in cross-section and of a size adapted to fit within the bore of the bucket 14. Secured to one end of the yoke 17 is a spring-latch 21, the lower end of which rests within an inclined recess 22, formed in the side of the standard 1.

23 designates a hopper supported by supporting-braces 24 upon the opposite guides (l and on about a level with the upper end of the bucket 14. The rear side of the hopper is open and its opposite edges provided with ways 24. The bottom 25 of the hopper is in: clined and is locatedat the lower end of the ways, and at the upper end of said ways there is journaled a loose, roller 26, over which is suspended an apron 27, one end of which is made fast to the front edge of the yoke 17, and the opposite end is connected to a gate 28, mounted for sliding in the opposite Ways 24 of the hopper.

29 designates a lever for operating the de vice, said lever being pivoted, as at 30, to the standard 1. A bail 31 is connected to the yoke 17 and at its lower end to the foot-lever 99, so that any movement upon the partof the foot-lever causes a similar movement upon the part of the yoke, plunger, and pressinghead 20.

32 designates a perforated guide-bracket secured to the standard 1 below the lever 20, and in said guidebracket is mounted a guiderod 33, the upper end of which is provided with a shallow recess 31L for receiving the lower edge of the lever 20, and is connected to said lever by means of a link 00. Encircling the rod 3 between the bracket and lever 29 is a coiled spring 36, which maintains the lever normally in a raised position.

In operation the hopperis filled with lemons, one of which is permitted to roll into the bucket 14 and down upon the knife of the strainer. This admission of a lemon is caused by a depression of the foot-lever, a consequentlowering of the pressing-head and yoke, and an opening of the gate 28. The foot-lever being released, the parts resume their normal position and the machine is ready for operation. The foot-lever being depressed against the tension of the spring 36,the yoke, guide-rod, and pressing-head 2O descend, as does also the spring-latch 21. As the head descends it entersthe bucket,which is pressed snugly upon the strainer, so that no juice may escape, and said head forces the lemon upon the knife, which knife serves to split the same, at the same time forcing the spring 13 to the rear outof its path. Further pressure being exerted, the juice is extracted, passing through the strainer and bracket and through the discharge-spout. By this depression of the head another lemon has been delivered from the hopper, so that when the foot-lever is released and the parts are raised or elevated a new lemon rolls into the bucket. As the yoke descends it will be observed that the inclined recess 22 permits the latch 21 to take under the lower end of the bucket, so that when the yoke ascends the bucket is elevated from off the strainer, and the spring tongue 13 being liberated serves. to eject the rind. WVhen the spring-latch has reached the upper portion of its recess, it is forced from under the bucket and the latter drops to its normal position, in which it is supported by the spring-tongue 13, and receives the fresh lemon, the operation thus being continued and lemons successively cut and squeezed, as will be apparent.

Having described my invention, what I claim is I 1. In a lemon-press, the combination, with a perforated strainer-cu p, a standard for supporting the same, and a superimposed knife, of a reciprocating bucket mounted above the strainer, a reciprocating plunger having a presser-head, means for raising and lowering said head, and a spring-ejector extending 2.
