Description

N. PETERS, PHOTO-LITHOGRAPHER. WASHINGTO Amove in guides 15. 4'are given to the said plnngers or pistons by means of General Description.

'lhe chutes A A are suspended, by pivots a a', from the bottom B of a mixer/Knot shown, which is intended to be located in the next story above of the building, or at suoli a height above the press as will iiisiii'e the rapid filling ofthe mold-boxes by the gravitation of the mixture of the coal-dust and itsagglutinating materials. The lower ends of said chutes open directly into thc feed-boxes C (l, but are not fastened thereto. 'lthe feed-boxes C C are open both at top and bottoni, and their bottom edges rest in close sliding contact upon the open mold-boxes D D below,

and arc'lield down or prevented from raising out of such contact during the pressure of the pistons or 'pl ungers E E upon the contents of the said mold-boxes,

when the latter are covered by the said feed-boxes, as'

will be described, byineans of cap-blocks F F, which fit over projections, 1 1, at cach end of' the coiiuected feed-boxes, in such a manner as will allow thesaid feed-boxes to slide forward and backward over the molds.

The forward or outer edge of the bottom of the said connected feed-boxes has' a flat projecting plate, 2, (sce fig. 4,) the under surface of which is iu the same plane with the bottoni edges of thc said feed-boxes, and, when applied in the saine plane, also with the upper surfaces of the mold-hoses, so that when the feedfrom time to time in the saine press, by means ot' removable or changeable plates 3 3, which can be readily inserted or withdrawn from between the said capblocks and the bed-plate of' the press, as the said changes in the molds may require.

ltwill be observed that this press is double-acting, or that both ends are fitted with the. changeable moldhoxcs and pistons or plungers, and with the feed-boxes connected with chutes respectively, so that, when the contents of the mold-boxes in one end of the press aie being-condensed and pushed out, the mold-boxes iu the opposite end will be filling with the mixture gravirating through their respective chutes and feed-boxes.`

'lhe requisite sliding motions of the two opposite feed' boxes C C are effected by means of two cam-cranks, 4 4, which come in contact, periodically and respectively,

v with two toes, 5 5, adjustabl y secured to two rigid bars,

(i (i, Ywhich firmly connect together-.the feed-boxes C C of the two opposite ends of the press.

The cani-cranks 4 4 are secured to the main shaft G, which has a large spur-wheel, 7, on one end, which gears into a pinion, 8, on one end of the driving-shaft ll, a baiul-wheel,.9, being; fixed on the opposite end ot' tlie latter in the usual `manner, whereby the required motions are given to t-lie different parts of `'the press. In each of the chambers A A there is a sha-ft,

. provided with an outside hand-crank, 10, and inside arms 11, whereby severe agitation can be given to the contents of the chutes should it be at any time desirable.

rlhe pistons or plungers E li of the mold-boxes D D of each end of the press are secured by set-screws or draw-pins 12, in an iron head, 13, which 'is reinov- `ably secured in an iron cross-head, I. The cross-heads I are ad j ustabl y secured together by means oftie-rods; with screw-nuts and jam-nuts, for the purpose, and lhe necessary sliding motions charging their contents.

double cam-cranks 16 16, providedv with friction-rolls 17 17 and 18 18, and fixed on the main shaft G.

The rolls 17 17 are changeable, byvme'ans of extra bearing-holes 19, or slots and blocks, as indicated by the dotted lines in fig. 5, to correspond with such changes in the adjustments of the cross-heads II, which the different sizes ofthe molds may from time to time rcqnire, because the tlirow-out motions of the pistons or plnngersinust always be of sufiicient extent to cause the ends of the said plu'ngers to come flush with the outside ends of their respective moldfboxesf, in dis- 4 The friction-rolls 18 18 p roduce the condensation only, and the variations in the mold-boxes are provided by adjusting the distance apart of the two cross-heads I I, As the shaft G is rotated, 4the successive condensing and .throw-out motions of the pistons or plnngers are ,effected by the force of the cam-cranks 1G operating against the crosshead I of that end of the press, which operation, at the same time, opens the niold-boxes in tli opposite end of the same, (see figs. land 2,) by sliding the feedboxes.

rlhe abutment-pieces K K are provided for the parpose of closing the outer ends of the mold-boxes D D previous to the filling of the same, of retaining their contents against the condensing pressure of the .pistons or plungers E E, and of opening the same for the discharge of the condensed blocks of fuel:

Each abutuiei'it-piece E consists of a verysti'ong and heavy piece of cast-iron, which is support-ed upon a horizontal bar, 19, by means of a pair of ruiming sockets, 20, each connected with two eye-bolts, 21 22, -by 4right and left screw-threads, so that `by rotating the sockets 20, the abutment K may b'e ,readily :id-

justed to the height required.

The bar 19 coiiuects the two opposite side levers, L L, at the saine end ofthe press,'and each of saidlevers has their respective fulcrums at 23, their powereiids being respectively fitted with steel friction-rolls 24 24, which traverse a groove inthe. inner side of respective hollow cams M M, fixed onthe shaft G, and constructed and applied so as to canse alternate rising and falling motions in the abutmentpiece K as the said cam is rotated. I

The abutment-piece K slides vertically in'tapering guide-grooiv's in respective adjustable blocks N N,V so that when raised up to cover the open ends of the molds D D, it will be held firmly in -close contact with the said molds, and, as soon as it is started downward, it will be free from any bindingvor frictional restraint from lthe said guides or grooves. f As a vcrypowerful pressure has to be resisted by this abutnient-pieceK, its guide-blocks N N are supported by means of strong wrought-iron grips O O,-sec`ured tothe bed-plate of the press by means of a T-head, 24', iu each, and bolts with lugs 25 25 on the bed-plate.

The grips O O are tightened against the blocks N- by wedges O O', and also connected by a tie-bolt, 26,

which. slips into slots in their ends, and is secured byv screw-nuts, so as to prevent the said grips O O from spreading apart. j

The upper side of the abutment-piece K is sloped downward, so as to form an inclned plane for the condensed blocks of fuel to slide freely down across it into the receiving-car, not shown,when the said piece K is at its lowest posit-ion, (see the left-hand end of press in fig. 4.)

As the abutment-pieces K K are each very heavy, a counterpoise, 7.1', is supported by au arm, 2T, fixed to the fulcruui-sha-t't of the. side-levers L L, and to the said eountei'poise, of sufiicient weight to relieve the hollow cams M Maud their friction-rollers 24: 24 from the excessive strain to which they would otherwise be subjected. j

The mold-boxes D D are in series of four or more in one piece, and are merely slipped outv and in a.

changesv iu them may require, and are so constructed that their centers are always parallel with the center 'ot' pressure. In the present case,'the corners of the mold-boxes are rounded, and their upper edges faced with steel plates 28, (see lig. (i.) The guides of the abutment-pieces are also faced with steel, and all the different parts of the press are made of the appropriate weight and strength of metal quired to stand tirmly the very powerful pressure required to condense the contents of the molds into blocks or lumps, nearly or quite as solid and hard as the natural lumps of anthracite coal.

The operation ot' this press will now be understood 'without further description or explanation, except t0 say that as the contents ofthe mold-boxes in one end of the press are being condensed and pushed out, the molds in theppposite end are being lled by the gravitation of the mass from the mixer above (not shown) through the chutes, aided by the vibratory motions of the latter, and that as the shorter knuckles of the cam-cranks 16 16 contain the friction-rollers 18 18, and give the condensing pressure, and the long'rer -knuckles ot' the said cam-cranks contain the adjustable friction-rollers 17 17 are required to give only the throw-out motion to the pistons or plungers, but two motions are required to condense and discharge the fuel from either end of the press.
