IMPROVEMENT IN HYDRAULIC PRESSES.

ro A LI. WHOM Ir MAY o'oNeEnIr; y l
Be it known that I, GEQRGEW. RAVWSVON, of Cambridgeport, in the county of Middlesex, and State of ll/Iassachusetts, have invented an Improved Hydraulic Press, to be used in the manufacture of lard-oil, of which thefollowing is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which-- v i Figure l is a perspective viewof my improved press. Figure 2 is a vertical section throughl the centre of the same.
'The' ordinary press used in the manufacture of lard-oil consists of a stationary bed'or platform, upon which are placed the bags of lard, the platen or follower being brought'down thcreonwith the required degree of pressure'by means of chains` and weights. Thispress is objectionable, however, as it occupies much space, is heavy, complicated, and expensive, besides reqniringlmuch labor to operate-it, while the chains, together with the heavy standards at the corners' of the press, interfere with the placing of the bags of' lard upon the platform, or their removal therefrom,
1 My invention has for its object to overcome these dieulties, and consists in a press in which the platform for the reception of the :lard is placed beneath a hydraulic cylinder, and conneeted'with the piston thereof by means of rods, which serve to raise the platform and give the desired degree'ofpressure to the lard to extract the oil therefrom, a press so constructed being simple, compact, and powerful, and at the same time easily operated. l I Y Toenable others skilled in the art to understand and use my inventon,I will. proceed to describe the manner in which I have carried it out. p Y Y In the said drawings, A represents the lowcriloor of a room or building, and B the door above, to which 'is securely bolted the cylinder -C of a hydraulic press, the piston D 'of which carries ya head, E, of smalldiameter. This head E is connected toa platform, G, beneath the ioor B, by means of four rods, a, bent in the form shown, and passing through the corners of a plate'or -spree1der, H, which serves to steady the rods and .retain them at the required distance apart, au opening, b, beingmade through the centre of -the plate, of a size suilicient to enable it to pass vfreely over the cylinder C', as the platform is raised er lowered by operating the piston. l The extremities cf the reds a are secured to the head E and t0 the platform .G-.by screw-nuts, c d, and by thus securing the rods to the four corners of 4the platform, it is held rigidly in place, and prevented from being tipped to onev'side or the other.
lhe plate or sprcader H enablesme to employ a head, E, of small diameter, which will resist a great amount of strain, whereas, if the plate H were dispensed with, and the rods carried-up in a vertical line directly tothe head,the latter wouldV require to be of large diameter', and consequently of great weightand corresponding cest, while the liability of its breaking would be much increased.
v By thus placing the hydraulic press C D above the platform G, upon which the lard is placed, instead of on the iioer beneath it, as has heretofore been customary, the space below the platform is left free and unencumbered, so that a pan (not shown) may be placed on the door to catch the oil as it drops from the lard, which is contained in bags, as usual, and pressed 'between the platformG and a' plate, I, secured to -the under side of -the door B above.
It willrbe seen that the platform G, with its rods a, occupies very little space, and that the lard may be easily placedupon it or removed therefrom, which is al great advantage where a number of presses are placed side by side.
A press, constructed and arranged s above deseribed,prescnts many advantages over those heretofore used, as many of the heaviest portions are dispensed with, thereby effecting a great reduction in cost, while it is simple, strong, compact, and easily operated. i
Whatlclaim as my invention, and desire te secure by Letters Patent, is Y The combination of the platform G, hydraulic press C D, rods a, and plate H, arranged to operate substantially as described for the'purpose set forth. i y
