RETAINER FOB HYDRAULICPRESSES.`
Specification of Letters PatentNo. 26,622, dated December` 27, 1859.3 i
To all whom t may concern:
Be it known that I,` CHmsroiHniz` E. RYMns, of` Charlestown, in the county of Middlesex and Stat-e of Massachusetts, have invented an Improved Retainer for Hydraulic or other Presses; and I do hereby declare that the same is fully `described and represented in the following specification and the accompanying drawings, of which- Figure l, is a top view. Fig. 2, a front elevation, and Fig. 3, an end elevation of such retainer. Fig. 1l, is a longitudinalsectionof it, while Fig. 5, is a horizontal section of the platen, its wedges, shafts, and other mechanism.
The article termed a retainer is used for receiving tobacco in suitable receptacles or boxes, transporting the same into a hydraulic press, and retaining or holding it while it is being pressed as well as for a suiicient period after it may have been pressed, the retention of the tobacco in a compressed state being kept up for a period sufficient for it to become set or so compacted that there may be little or no expansion of itafter its removal from the retainer. With a `hydraulic press it is `customary to employ several retainers which by means of wheels andrailways are conducted to and from the press.
The lower part, or bed plate A,of1each retainer is `furnished with` two sets of railway wheels B B; B' B', mounted on axles C, C. From the part A, two metallicbars, posts or standards,.D, D', extend upward vertically or at right angles to the top surface of such bed. i Each of such bars, D, D', `is furnished wit-h a` toothed rack, a, arranged on it as shown in the drawings, the same being to receive and engage with one of two gears or pinions, b, b, which are fixed on a key shaft c, that extends through and is supported on a platen or follower, F, throughwhich the bars D, D', pass. A ratchet d, is fixed on the shaft, near one end of it, and is furnished with a retaining pawl e, which turnson a pin or journal f, projecting from the follower E. Another key shaft, g, also extends through and is arranged horizontally on the follower and parallel to the first named key shaft. This shaft, g, is furnished with two male screws, h., z', whosethreads are pitched alike and in opposite directions, one being a right and the other, a left screw.` These screws work respectively `in ,female screws.. formed 1n two armsc, lo, each of wh1c`h`fprofl f jects from one of two wedgesZ, Z,\in manner* and wit-hin a recess, m, formed inthe platen 1 3 E as shown in the drawings. Q Furtherniorea i each rod or bar, D, or D', isfurnished with` two or more slots n, n, arranged 1n rear of` L its rack and in other respects as shownin the,
figures.
BY ilpplying a crank key the ghftl. and revolving it, the wedges may be made a either to approach tliebars D, D', or recede from them and therefore,"wheneveritmay be necessary, the wedges may be` caused "tou y y enter the slotsof the bars `and operate to con-` fine the platen in positionor from rising up ward, after removal of the hydraulic pressf from it.
I am aware that. a tobaccopress retainerf" has been constructed notonly withscrewsl upon itsuprightbarsbut1with nuts` (in lor on its platen) to work onsuchscrews; "llhesewf,4
are objectionableonaccoimt of the difieulty` i of turning them back, the greatexpenditure l i of time required to` revolve them sufficiently"` for elevating the platen 1to the height re-y quired for loading the `reta1ner,"as well as] I` the difficulty in maintaining the horizontalf ityof the platen. i There are other disadva`n-1z` f 1` tages attendant upon them which are obi -viated by my invention.
By the employment of twowedges oper-"p` l ated simultaneously bythe revolution lofone y y shaft and its two screws`,`the platen may notl only be correctly locked down, butwill-"be" y caused to always maintainitsparallelism` to` the bed. Furthermore, the` arrangement of` the wedges and screwlshaft within a recess 1 in the p causes the said wedges andtheir operative aten and to operate with slots Iar-` p ranged in the standards or bars as described, y f mechanism to be out of theway of the platen C .y
of the hydraulic press,fand enablesto 1 close down upon thevfollower By means of the racks upon the bars. and i` the pinions fixed on one shaftand arranged on the follower as described, the elevation of 3 the follower after withdrawalhof the wedges from theirslots canbe effected very expedi: 1
' tiously. l
What therefore I claim is`l i 3 l 105` l. The arrangement and application of the M two wedges and their operative screw shaft`,
