CIDER-PRESS.v

SPECIFICATION forming part of Letter Patent No. 313,322, dated March 3, laas.

' Application mea september 17, 1884. (No model.)

To aZZ whom it may concern.'

Be it known that we, JACOB GoRGAs and GEORGE E. MOHLER, citizensof the United States, residing at Ephrata, county'of Lancaster, State of Pennsylvania, have invented a new and useful Improvement in Cider-Presses, of which the following is a specification.

This improvement is more particularly related to the juice-extracting portion of a cider-press, and is intended to be continuous in its operation. v

The object of the improvement is to furnish a combined cider mill and press adaptedto be operated by hand or power, in which the juice of the fruit shall be extracted in a continuous stream and without exposing the same to the light, thus producing a clearer and better article of cider than can be manufactured in the ordinary class of cider-press mills. The above objects are attained by the use of the improvements shown'in the accompanying drawings, inwhich corresponding letters indicate corresponding parts.

Figure 1, Sheet l, is a perspective elevation of a cider-mill with our improvement attached. Fig. 2, Sheet 2, is a vertical longitudinal section through the center of the frame and machinery. Fig. 3, Sheet 2, is a detached sectionv of the fabric or wire-screen endless apron with its special rolls. Fig. 4, Sheet 2, is a detached section of the rubber or equivalent non-absorbent endless apron and its special rolls, together with a portionY of the gear for driving the same, shown therewith. Fig. 5, Sheet 2, is a sectional elevation of the movably-adj ustable bearing-box, spring, and adjusting-screw. Fig. 6, Sheet 2, an end view and longitudinal section of the perforated juiceextracting roll.

The construction of our improved press is as follows: The crushing or grinding rolls may be of any of the forms suitable therefor. We make no claim thereon. Immediately beneath the crushing-rolls, in suitable bearings'4 upon a rail, A, we arrange a series of rolls, D, H, F, and H', the bearings of D and H being permanently secured to the rails, and the bearings of the rolls F and H' adapted to slide upon the same. An adjustable roll, E, is held in angle brackets or pedestalssecured to the lower rails, A, of the frame.

Endless aprons are placed over the several rolls as follows: A canvas, wire, or porous belt or apron, G, the full width of the rolls between the collars, is passed around the front roller,D, beneath the roll H, over the roll F, down to and around the adjustable roller E, and returns to the roll D. A rubber or non-porous apron,

L, is passed around the roll H until it meets l the perforate roll F, over which it is passed above the apron G. It is then passed under and around the roll H', and is carried across the top ofthe roll until it meets again over the roll-H.

` To facilitate the introduction ofthe aprons in au endless form, we make the rails A3 removable, boxing or gaining them into the sides of the posts. The aprons provided in endless form, we lay the machine over upon its gearing side, and removing the securing-bolts we lift the rail with the bearings away, (having previously withdrawn thescrew-tenon J from the stem-guide I2 of the spring,) and slipping the roll E out ofthe inclined pedestals E2 we first pass the apron over it, and reinserting the roll in its pedestal the apron is next passed over the iolls D and F and dropped beneath the roll H. The rubber or non'porous apron is passed simultaneously over the rolls H H' and roll F, the rail A3 is again let into place, the shafts entering their respective bearings, the rail is secured by its bolts, and the adjustingscrew tenon J' is brought in contact with the recess Il in the spring-stem, and the machine is ready for operation.

The rolls D E H H' are preferably made of wood, while the roll F is preferably made of brass or copper, or a suitable metal that will not discolor the juice expressed from the fruit. The roll is cast or formed of a suitable thickness to withstand the strain to be brought upon it, and is drilled with a series of holes of from one-eighth to three-eightlis of an inch diameter, according to the texture or mesh of the porous apron G resting upon the same.

A tightener-roll, M, is suspended between the bifurcated arms N2 of a lever, N, and rests upon the apron L. The lever N is fulcrumed at N upon the inside of the top rails, A.

Upon the extended arm N a weight, P, is

hung of sufiicient power to keep the rubber or non-porous apron taut upon the .rolls H F H.

A gutter or trough. R, is suspended beneath the rolls D, H, and F, and is provided with a discharge-pipe, S, which is clamped to the post at T. rlhis pipe may deliver into a closed receptacle, but we prefer to deliver direct into .bottles V by tunnel U, a shelf, NV, beingprovided to receive the same while being filled.

The operation ofthe press is as follows: Ihe fruit is placed within the hopper C and the rolls B revolved, either by hand or power, according to the size of press operated. The gear-wheel H5, secured to the shaft of the roll H, and in mesh with the pinion B2, transmits a slow movement to the roll, and by the'connection therewith to the aprons G L. The pomace falls upon the aprons below and is caught and held between the same. While it is thus held, it passes beneath the roll H, over the roll F, and between the roll-s F and H', the aprons separating after passing the center line of rolls F and H', the pomace dropping to the floor inside of the frame.

Any of the various forms of conveyer may be-attached to the machine, and being suitably connected with the moving parts thereof would carry the waste pomace out of the way; vbut in small hand-machines they may occasionally be lifted to one side and the pomace shoveled away.

As the pomace passes between the rolls D H, it receives a preliminary squeeze, the tension of the aprons gradually intensifying the pressure until it arrives at and passes between the rolls H F at one side of the perfoas a dry pulverulent mass.

rated roll F, and between F and H at the op' posite side of the same. As the rolls H' and F are movable horizontally by the action of the screw J uponthe springstem I', any required amount of compression may be produced, and the pomace will leave the Iaprons The spring I prevents breakage by permitting the rolls F H to recede in case obstructive articles should be carried through the crushing-rolls upon the aprons.

We are aware that we are not the first to produce a continuous press, or to make use of endless aprons in connection therewith; but we believe our improvement to be anovel and useful-advance in arrangement andV in the result produced over the presses which have preceded ours.

In manufacturing cider by the ordinary press the pomace becomes discolored from exposure to the light and air, and before it can be brought beneath the press, where the action of the same is intermittent, the cells close up from the thickening of the pomace, and the juice is not as readily expressed as when the operation is a continuous one, as with our improvement. Cider made by our process needs no clarifying, but, as described, may be run into the bottles direct, and be immediately corked and set away to age for the export trade. y

VHaving described our improvement, shown its construction and advantages, we desire to secure by Letters Patent the following claims thereon:

1. As an improvement in continuous juiceextracting presses, as described, the fixed imperforate roll D, adjustable imperforate tension-roll E, andmovably-adjustable perforate roll F, with the porous-fabric endless apron G, in combination with the fixed imperforate roll H, and movable adjustable imperforate roller H', the non porous apron L, gear H5, pinion B", and crank B3,substantiall y as shown, and for the purpose set forth.

2. In a continuous j nice-extracting press, as described, the iixed imperforate roll H, and adjustably-movable imperforate roll H', with the non-porous endless apron L, in combination with the perforate roll F, apron G, imperforate rolls D E, gearwheel H5, pinion B2, crank B3, rolls B, springs I, adjusting-screw J, and tightener M N, substantially as and for the purpose specified.

3. In combination with the rolls D, E, F, H, and H', aprons G L, the roll M, with its lever N, arms N, fulcrum N', and weight P, whereby a variable tension is produced upon the apron L, and the pomace held between the IOO IIO

6. In a press, as described, provided with the rolls H F and bearings F H2, the springstem I', having a spring-seat, and recess I2, in combination with the adjustingscrew J, its tenon J', hand-wheel J2, nut K, helical or gum spring I, and post A, whereby the pressure upon the rolls is adjustable and unusual strains provided for, substantially as shown, and for the purpose hereinbefore set forth.
