VBRICK-MOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,715, dated April 10, 1883.

i Application sied January 10,1582. (Nomea-.1.)

To all whom it may concern Be it known that I, CARL FRIEDRICH SOHLIGKEYSEN, of Berlin, in the Kingdom of Prussia and German Empire, have invented an Improvement in Brick-Molding Machines, of which the following is a specification.

My invention refers to an improved brickmolding machine in which the pressing-cover is lifted or shifted from the press-box by means of a direct movement of the hand; and it is based upon the application of the said direct movement of the hand in lifting the said pressing-cover and dropping` the same in proper time.

My invention is illustrated in the accompanyin g drawings, showing the several modili cations of my said machine, like letters indieating the same or identical parts of the same. I have chosen the said letters of reference in such a manner as to have each main part of machine indicated by a separate letter, while the under parts belonging to the said main parts are indicated by the same letter and continuous numbers attached to the latter.

Figure lis a side view, showing one modification of my im proved machine in vertical section. Fig. 2 is an end view, showing the same in transverse section; and Fig. 3 is a top. view of the same modification.`

A is a table-plate on the standards A', being connected by the cross-piece A2, said tableplate having an inclined arm bifurcated at its upper end and carrying the shaft B. Upon the latter is fastened a star-piece, B, with striking-lever B4, weighted lever B3,and pushing-lever B2.

The brick-mold C is screwed upon the fore part of A, said mold having a movable bottom, C5, and a cover, C', fastened to the striking-lever B4. The small shaft C2 is .journaled in bearings on the cover-plate Csaid shaft being provided with two catches, O4, the fore one of which having a lever, C3, extending in an upward direction. Said catches O4 catch under another pair of catches formed ou the mold C for the purpose of fastening the cover upon the mold while the brick is being pressed.

O6 are two hanging arms connected with each other and carrying the said movable bottom C5. They are provided with the roller C".

vD is a double rail moving between the fixed rollers A3, and having a small catch-lever, D, pivoted to its end, which can turn in a backward direction only. The fore part of the rail D is provided with the inclined loop D2, pivoted at its lower fore end, and being made adjustable at its upper end in an upward and downward direction. The roller G'I runs in the said loop D2. The bent lever D4, with weight D5, is pivoted at'A5 to the cross-piece A2, and its upper end is held between the pins D9 D1U and the double rail D, so that it is bound to move with the latter.

Eis a shaft journaled underneath the tableplate A, having between the arms U6 a cam, E', and a lever, E2, the latter being connected to the lever E4, pivoted at E5 by means of the connecting-piece E3.

- The operation of the machine is as follows: By raising the striking-lever B4 the pushinglever B2 strikes against the catch-lever D and moves it forward. 'At the saine time the loop D2-lifts the roller C?, and thereby the moldbottom C5 is raised above the upper edge of the mold C. The brick molded in O is consequently brought to the outside, and can be taken O', whereupon the pushing-lever is pushed entirely over the lever D. rlhe weight D5, having been raised by the forward movement of D, drops down again and presses the rail D back again -by means of the pins D10 and D9. The same effect on the rail D might be produced by the weight D5 being connected to the latter by means of a rope and pulley. In consequence of the backward movement of D the roller O runs down again until the bottom C5 rests on table A, as before. Loam is -then inserted in the mold C and beaten down by the striking-lever B4 and cover C', whereupon the latter is fastened to the mold by means of the catches G4. Hereupon the lever E4 is pressed down, which causes the brick in the mold now to receive a pressure from below after it has been beaten down from above. Finally the cover is unloosened, and lever B4 is raised again to bring bottom C', with the molded brick, to the outside, as above described.

It' one blow by the lever B4 and cover C should prove to be insufficient, and several strokes must be made, then the catch-lever D must be brought out of action, so that in raising the striking-lever the pushing-lever will not move IOC forward the rail D. For this purpose a drawing-rod, R. is pivoted to the table-plate A, as shown in Fig. 4 of the drawings, the lower end of said drawing-rod being held in a perpendicular position by the weight R2, and being connected by means of a light chain, B', to the lower end ofthe catch-leverD. rIhe drawing-rod is also provided with a light rod, B3, extending with its handle through an aperture in the frontispicce of the table-plate A, and having a catch, lt. By drawing the rod R3 to the outside until B* catches behind the lower edge ofthe said aperture the catch-le ver D assumes an inclined position, so that the moving pushing-lever B2 cannot touch it. The entire apparatus and thelever D', by means of the drawing-power ot' the weight R2, will at once assume their normal position again as soon as the catch It is set free.`

The said Fig. 4 shows another modified con struction of my improved machine. rlhe loop orincline D2 has been substituted by a rack, D, and pinion D?. Iart ofthe said pinion I)T is made with a. smooth rim, D8, and acts like a cam carrying the roller C7, with bottom C5. By raising the striking-lever B4 the rack DU is pushed forward and rotates the said pinion D7, the smooth part DB of the latter thereby lifting the roller C7 until the mold-bottom, with the brick, lies free above the mold G. Now, when raising the lever Bt is continued, the le- D will swing free, and rail D will be pushed back again by the weight D5 coming down.

The pushing-lever may in some instances be dispensed with, and the movement ot' raising the said striking-lever by means of leverpressure may be applied in a direct manner for lifting the mold-bottom and dropping the same; but these are mere mechanical modifi cations and combinations of parts known. I therefore shall but refer to two of such moditications.

In the modification shown in Fig.5 the hanging arm U6 is connected rigidly to an arm, G8, extending from the table behind the mold and terminating in a catch, B2. The catchlever D' is fastened to the striking-lever B4, and in raising the latter the said lever D carries the catch B2 and the mold-bottom C5 above the edge of' the mold. Then the brick has been taken off, thelever B4 is raised a little, whereupon the catch B2 slides off the lever D', and then drops down. Now the mold is refilled and the striking-lever B is brought down, the catch-lever D' turning on its pivot, as hereinbefore described, as soon as it touches the said catch B2.

In the modification shown in Figli the hanging arm H is made movable,the same, near its lower end, being guided between two rollers, A3, and having above the latter the catch B2, rigidly connected to it. The catch-lever D is applied to the hanging arm C, while the manipulation and operation are the same as described with reference to Fig. 5.

In the modification shown in Fig. 7 a second lever, K, is applied to the standard A', said lever K being connected to the strikinglever B4 by means ot' a drawing-rod, I'I. The catch-lever D is arranged and operates the same as in the modification shownin Fig. 6.

In any of the instances referred to it is not material for the catch-lever to drop back again into itsnormal position by means of its gravity. Such movement may also be provided t'or by a spring combined with the said lever in any suitable manner. Neither will it be necessary that the said movement be a turning movement,asinscmeinstances a sliding movement, as indicated in Fig. 12, may be applied with advantage.

Figs. 8, 9, 10, and 1l illustrate the construction and combination of the lockingeatches with the two faces of the mold. The said catches consist each of a thin plate, M, fitting in a tapering slot cut in the said faces, and are tightly held in position by means of pivots N, extending from each face through each plate, and holding the latter in its place by means of a splint. The said plates M are provided with strong rims made of steel, the horizontal parts of which also serve for holding the toggie G4 ofthe cover during the pressing. Binding a thin plate like M by means of lockingcatches may also be effected, as shown in Fig. 11. In this instance the saidplateon its upper outside carries the locking-catch o, and on its inside it has several cross-pieces, p, the upper rim of which has an ascending form, and tits dovetail-like in a corresponding slot cut into the outer face ot' the mold. By means ot' a small wedge, q, the whole plate is then keyed in an upward direction, so as to be prevented from talling out. The said plate may be stiffened in any convenient manner, whileitis obvious that the cross-piecesp may be arranged different from- Fig. ll. Ihe said cover-plate may enter the mold from about one-fourth to.

three-fourths inch, so as to compress the ma terial in the latterjust sufficiently to prevent its escaping from the mold.

In the modification shown in Figs. 12, 13, 14,15,16,and 17 the mold is laid open by means of shoving or pushing off the coverplate, instead of raising the same, as in the modification hereinbefore described. W'ith this modification the pushing movement is utilized in the same manner as the said lifting movement-thatis to say, the movable bottom is brought out of the mold while the latter is open, and is dropped again in proper time for refilling. With this modified form of my improved machine, beating down the brick is dispensed with, while the mode ofpressingis the same as hereinbefore described. 'Ihe tableplate A is provided with two grooves for sliding the frame F in a forward and backward direction. The said frame F is connected with two standards, F', wherein isjournaled a cam-shaft, F3, carrying the cam F4. Between the said standards the ram or stamper C slides up and down, inclosing at the same time the ICO lIO

said cam F4 on both its upper and lower side, the said stamper G', by these means, being bound to follow any movement of the said cam F4. To the said table is iXed the arm A", having a collar for the short spindle F, the latter ou one side, being provided with an open slot,

F5, while on the other sidelit carries a ilywheel or pressing-lever. A square-edged pivot on the cam shaft F3 tits in the said open slot F5. The armi) is fastened to the crosslpiece on the back side of the frame F, said arm extendingfrom under the table A, and is provided with a projection. An inclined bar, D', is pivoted to one side of the said project-ion, and with its lower end rests upon the arm D, the latter, by means of two rollers applied thereto, being carried by the frame-piece A2. To the mold-bottom G5 is suspended the arm G6, having a roller, G7, the latter being suspended within a short distance from above the arm D. The said roller is touched by the inclined bar D', being pushed or moved underneath the same, so that in pushing backward the frame F with arm D the saidiuclined barD' will raise the mold-bottom U5 until the latter is raised above the upper rim ofthe mold O. The brick formed is then taken off the said bottom C5, and the frame F pushed backward a little farther, so that the roller C', with hanging arm G6 and bottom C5 will drop down again, and

,fresh material may be inserted into the said mold C. The frame F is then pulled-forward again, the said roller C7 passing by the projection D2 and raising. the inclined bar D', resting loosely upon the arm D and being pivoted to the said projection, as hereinbefore described. In pulling forward the frame F the edge of thev cover-plate C', sliding closely across the mold C, will take away all the loam 4c jutting out of the latter. Then the cover-plate C' has assumed its normal position above the mold G it is pressed down by means of turning the cam-shaft F3. The latteris then turned back again and the frame Fpushed backward, as before described. The said cam-shaft may be turned by means ot' a lever or ily-wheel, either directly connected therewith or connected with its short slotted spindlel F6, journaled in the arm A6. It is obvious that the said cam-shaft F3 may also be applied to the frameA2 of the table, and may be provided with one cam each outside of the said frame, as illustrated in Fig. 16 of the drawings. The cam F4 is connected with the pressing-cover by means of two .drawing-rods, F', the upper ends of which are bent rectangular, the pressing cover being kept continually in a raised position by means of springs or weights, and being provided with a cross-piece, F3, projecting laterally from its sides, said projections catching under the rectangular endsv of the drawingrods F7 in pushing forward the frame F. The operation of qthe modification is obvious and need not further be described. With this modification, also, the raising of the molded brick may be effected by means of a combinahaving pivoted thereto the elbow-lever G G',

the lower part, G', of which is connected to the hanging arm C6 by means of the connecting-rod H. To the other or fore end of the bent arm D isv suspended a catch-lever, D', which, in pushing backward the frame F, with the said arm D fixed to the same, strikes against the lever-,arm Gr, and carries the same along until, by means of lever-arm G', connecting-rod H, and hanging arm C6, the pressing or mold bottom has been raised out of the mold. Then the operation is interrupted for a moment, and the molded brick is taken olf the said bottom, whereupon frame F and arm l) are pushed backward a little farther, so that the lever-arm G will slide ofi' the catchlever D', in consequence whereof the parts G' H GG and the mold bottom connected therewith will drop down again. The mold is then refilled, and frame F, with arm D, is pulled forward again, the catch-lever D', pivoted to the arm D, sliding across the leverarm G.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
