I flit: 5x11211111: trim): in in that Ztetteri haunt are making gm of the time.

Be it known that we, JoHNA. remorse and Roennr GRAHAM, of, JerseyvCitfl Hudson county, in the. State of New Jersey, have invented certain newand useful Improvements in Machines forlMaking Bricks; and.

\ we do hereby declare the following to he a full, clear, and exact description thereofireference being had'to the annexed drawings, making pert-of this specification,'in which-J. I I I Figure 1 is an elevation of that side of the machine from which the moulds aretak'en away by the bearers. I Figure 2 is an elevation of the contiguous side. V

Figure 3 is n. vertical section on the line X-X of fig. 1; and Figure 4' is a'horizontal' section on the line XI-X I-of fig. 1. I In all the figures like parts are indicated the same letters of reference. In the d ra\vings.- I I A-is'a box or chest, supported by the uprights and braces A, in which, attached tothe' vertical shaft- ]3, revolve the knives a, for thoroughly mixing thewet clay'whrch has heen fed in'at the' t0p.- I

At the bottom of the'shaft B, and. firmly attached thereto, are .the cur v'edIarms Or wipers 6, which, -as they turn, wipe or force the clay which isat the bottom of the chest A, and is in a propei-ioondition, into. .the pressbox C. 'This press-box is on the outside of the chest A us shcwh in figs. 2 aud 3, end-is closed on'its front side, or that side which is farthest from the chest A. v I I 1 V The bottom, which is open,'is crossed auddivided by gr'ate bar's, which correspond in width and position :with the partitions'in the iziouldsused, which'separat e the bricks."

- The press-box is fitted with a plunger or follower, c', which fills'its length 'and breadth, and whichwillbe morev particularly descrihed-hereafter. I I l i I i i i The back ofthe press-box, or side n'ext the chest A, is open, except dvhen closed by the-descent of a. gate, 0, forming part'of the plunger 0. i I w 1 The moulds mev be of wood'or any other suitable material, and are the briclrs'o are mode, and may each have as many. spaces for bricks as the capacity of the machine and convenience ivillallow; I, I: I t 1 The shaft B is driven by any convenient means hr powef, and it. furnished, near its top, withefixed bevel-cog wheel, D, gearing into and; givihg motion to another cog-wheel, E, fast ontone end 'of the horir ontal shaft E. The other end of this shaft carries a. crank, F, the wrist or pin F' of'whi'ch has'ffree play inthe slot- A of the slotted lever G, swinging loosely on the arbor 07, secured .to one of the hraces of the frameA" Afot" the machincf I I 3 I 7 Loose on the some arhor, d, is a segment-toothed wheel, G, the teeth of which take into a rack, G,

attached to and forming'the stem-of the'plunger a, fitting the press-box'G. I v

As the lever G is vibrated by the craaik and pin F .F itcomes in contact with-e. pin, permanently fixed in 'hnd' projectingfrora-the segment G, so as tocause this last toturn on the arbor d, in a directio n that'wil'l lift the rack G"'"and-vthe plunger a." Y I I I y Another pin, f, is inserted in one o? a number ofjarljusting-holes, f. in the segment G, on the opposite side of the lever G from th e'piu 0, so that'the lever'shall bebetween the-twopins, which pin,j, hycontectwith the lever G, causes the segment'G' to. move, so as'to depressthe rackG"hnq; -gplunger c as the revolution of the crank F continues. The holes f are made at variable: distances from their-axe, so that the lever G may will be at rest bet-ween its upward and downward movements; I I p A gate, a, forming part of theplunger c, and setting at-right angles with it, .descends'v'rrth the plunger I The position of the pin 3 thus regulates the lengthofthe stroke of the plunger c, 'nndthe length of time it i r the cog-wheel'I and crenl: K.

and closes the back of the press-box againstthehdniission'of clay, while the plunger is exertingjits pressure on the clay in the 'moulds beneath .j k v On thc'front ofthe press-box is a. gate, H, fit ted closely to the front of -the boit, and sliding up kind down in guides, 9, st each end of the press-box. The gate H is furnished at each end with a short. rack, h. Into each of these rocks meshes a. small segment-toothed wheel, 71,, on each end of :1 rock-shaft, i, which has its hearings in brackets on the press-box C, and is vibrated'by the lever z" when'it is necessary'to lift the gate H,

for the purpose of clearing the press-box of stones ornnythin'g that may interfere with the proper action of the machine. I 7 p p The bevelled-cog wheelD, at the upper end of the shaft B, engages with another bevelled-cog wheel, I,

I fixedon the horizontal shaft 1, which she Ft carries-at its outer end a. crank, K, having a crank-pin or wrist, it.

As the crank K revolves, the pin it comes in contact with and catches under the hook L, attached by a. joint, at Z, tothe upper end of the connecting-par M, which is kept in a. position to be engaged by the pinit, by the adjustable bridle and guide m, As the pin revolves, it.lifts the hook L and bar M, and, as the lower end of the her is connected with a. lever, M, on the end of the rock-shaft N,'t-his last has a vibration given to it, due to the proportions oi the crank K and lever M. i i I l The rock-shaft,'which extends across the front of the machine, under the mould-bed or platform, has its hearings in brackets attached to the upright, A, of the machine, and-hes two arms, 1 n, which extend upwards as high as the mould-bed 0 in each side of it, and are then connected bylin-ks or rods to a. pusher, 1?, extending across the'mould-bed, and slidingfreely over it. r j v i i l It will be seen that, as the pusher is brought forward, which happens while the plunger 0 is down, the emptyjnould, which has just been plnced between the pusher andhtheone that was lost filled, will becorried under the press-box to be filled :i-trtne next depression of the plunger 0, and will push out the one already filled from under the press-box, to be token away by the 'beerenwhen another empty mould will be placed between the receded pusher P and the' inould now under the press-box. This operation is repeated for every revolution in .frame of the pusher P is provided with a spring, R, shown in blue in fig. 4, which is slightly compressed when the gushcr is forcing a mould'forward, and whose elasticity helps to send the pusher back when combined withfi'itb weight of the bar M, to cons e the rockshaft ,to return after the hook L is relieved'from the pin k of the crank K r The platis m on which the moulds rest, and over which they are impelled by the pusher P, is composed of' a number of rollei's.p 1), so nezirly flush with but a little above the platform or mould-bed that the moulds will run over them with the least possible friction while, at the snme time, they presentssuflieientamount of resistance tothe pressure of the plunger 0. 1 V jlt may happen that, by a fuilure to properly insert. the empty mould, by the interposition of e'stone or hirnp of clay, or some other accident, the pusher might be checked in its motion when it or the mould would be l inhle to be brokem or the rock-shaft N, or some of its adjuncts, would give way, causing serious inconvenience, and n stoppage of themnchin'e. v

As it guard against any such diificulty, the hook L is hinged to the upper end of the connecting-bar M by the joint I, and is kept in the proper position for the action of the pin]: on the crenk'K, by a spring or series .of springs, S, which acts on the back of the hogk L, in nearly the snipe manner as the spring at the back of a.

ponknife actsupon the blade. The spring may be composed of'n number of bars or laminae, according to the .eiegree of stiffness required, and is secured to the bar M by nclamp and screw, as seen in fig. 2, or by any other equivalent device. The stifiness of the springmey, moreover, be further regulated by changing the position of the elnn p, whieh holds them to s greater or less distance from the hook, thus lengthening or shortening the spring. TI? anything should happen to check the movement of the rock-shaft N, the spring S-will cllowthe hook L'tp vibrate on the joint 2, until the pin he! the crank K shnll have cleared the hook and passed it, when it (the hook L) will in'stan,taneously.return to its proper positionfor renewed action, which will bercpen'ted without danger to the machine, until the obstruction shall have been removed. Having thus fully described our invention, what we claim therein as new, and desire to secure by LBBWR Potent, is-- i J 1. The hinged ho k L, in combination with the spring .8, connecting-rod M, and cranlopin k of the crank K, connected with the driying-power of the machine, substantially as and for the purpose described. ti ln eombinntionwith the hinged hook L, spring S, connecting-rod M, and crenkspin It of the crank K,

, thendjostoble clamp m, in constructed and arranged substantially as and for the purpose set forth.
