JAMES HUTCHINSONIOF FQND DU LAO, WISCONSIN.

Letters Patent No. 75,166, dated llfarclt 1868,

IMPROVED HOP-'PRESSi art-strata were it in the: Elders time nut mnti'ngpzittttmam.-

TO ALL WHOM IT MAYUONCERI a Beit knownthat I, Jhiuns HU'rcnINsoN, of Fond du Lac, in the county of Fond du Lac, and 'State ot' Wis consin,"have invented certain new and useful Improvements in Hop-Presses; and I do hereby declare that the following is-a full,'-clear, and exact description 'th'ereoi', reference being bad to the accompanying drawings making part of'this specification, and to the letters of reference marked thereon, likelette'rs indicating like parts wherever they occur. x

To enable others sk-illed'in tlie art to eonstructand use my invention, I w'ilI proceed to describe it. My invention relates to presses for hops and similar purposes, and consists of new, useful, and certain improyements in the hop-press for which Letters Patent, dated July 16,1867, No. 66,793, were granted to Newell Carpenter and myself, by which I am enabled-to make it more eflioient for the purposes for which it is designed, In the drawings-- Figu're'l is a view ofa longitudinal vertical section, and V Figure 2 is an end view, with the ban Llle of the leverleft oil, and a portion of the movable block broken away. I construct the bed A, the upright, B, madaby slotting a single piece of timber, or ofitwo pieces, with a block' interpbsed between their lower ends, and provided with the plates 0, having ratchetvteeth on their interim: surfaces and on their inner edges, as shown in figs. 1 and 2, and fully described in said Letters Patent, No. 66,793. The beam D, which is presscd-(lown by the mechanical arrangement hereinafter described, is'provided with the pawl s a, which are held in place against the ratchet-teeth on the inner edges of thelplates C by the springs'b, as shown in fig. 1, and the movable block E-is arranged to slide vertically in the upright,-B, and is provided with the'dogs c, which are held in plaoe by the springs d, as shown in fig. 2, and-described in said Let-- tersPatent. Near theend of the cross-bar or beam D, on its upper side, and so as to be within the slot of the upright, B, I mount a roller,F, flanged or not, as may be, desired, between two strong bearings, e, which are firmly attached to the beam D, as shown in figs. 1 and 2, and tothe lower side of the block E, atf, I -'p ivot the head, H, of the' lever G. The lower side of the. head, H, of the lever G I shape or curve, so as to makeit eccentric, about the pointf, so that the-distance from the pointfto the lower side of the-h eadot'the leveriwill constantly increase on either side of a line running through the centre of the upright, B, when-the lcve'rvs'tands at right angles to this upright, as shown in fig. 1. I provide each end of my press with thismechanical arrangement, and, in operating it, place the hops or other substance to be pressed between the-bed .AQ-and beatn l), th en squeeze together the dogs 0, if necessary, and drop the blocks F till the heads H of the lovers come in. contact with therollers-F, then work the levers by moving their. handles up'and down As the head His eccentric, as; it moves backwardand forward over the roller-F, it will continue to press from one endof its curve to the other. Asthe-bea'm D'is'p'ressed'down, the pawls more with it, and hold it in place. [At the same time the block E follows down, and is held in place by the dogs 0. Both endsof the press are worked at the same time. .When I p the hops or'other substancenre sufliciently pressed, theyarc baled..' The beam D is again adjusted by s'queezing the dogs 0 and elevating or raising the blocks Eyand the process repeated zisbefore. I i i 'In the Letters Patent mentioned, the pressure was not constant, and ceased whenever the handle of the lever was elevated or lowered above or below a certain point. By the use of the eccentric-head H, as herein described, the pressure becomes greater as the handle of the lever is elevated or lowered" rendered easier by the use of the friction-roller F,'a nd in.this wayI a'menabled to construct and-furnish a press having great advantages over the one for which the Letters Patent were previously granted to me, and as being a. greatimprovemcnt on the same.

Having thus described my invention, what I claim is The improved mechanical arrangement for pressing hops and similar substances, consisting of the hinged. lever-G, with its eccentric-head H, block E, provided with the dogs a, in combination with the ratchet-plates C and beam D, provided with the'roller F and pawls a, when constructed and arranged to operate as described.
