Application filed July 18, 1884. (N model.)

To all whom, it may concern.-

Be it known that we, EDWARD FALES, of the city of St. Louis, in the State of Missouri, and Izorm MCMANIS, of Hamilton, in the county of Hancock and State of Illinois, have invented a certain new and useful Improvement in Brick-lllachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,form- 1o ing part of this specification, and in which- Figure 1 is an end elevation, the simple lever being in section. Fig. 2 is a top view, both the simple and the compound lever being broken off. Fig. 3 is a side elevation with the I 5 levers broken off. Fig. 4 is a detail horizontallongitudinalsection taken 011 line 4 4, Fig. 11. Fig. 5 is a detail vertical transverse section takenon line 5 5, Fig. 11. Figs. 6 and 7 are detail vertical sections taken on line 6 7,

Fig. 9 is a similar View taken on line 9 9, Fig. 11. Fig. 10 is a similar viewtaken on line 10 10, Fig. 11; and Figs. 11 and 12 are vertical longitudinal sections taken on line 11 12, Fig. 1, showing some of the parts in side elevation, Fig. 11 showing the parts in the position they occupy when the machine is at rest or before the plunger-s are brought together to press the brick, and Fig. 12 showing the parts in the position they occupy just as the brick is finished being pressed.

Our invention relates to a brick-machine adapted to be operated by handpower through means of a simple and compound lever; and our invention consists in features of novelty hereinafter fully described, and pointed out in'the claims.

Referring to the drawings, A represents the frame of the machine.

B represents the upper, and O the lower, plunger. The upper plunger is. supported by and has vertical movement in a head or frame, B, made open, forming two bearings, as shown in Figs. 1, 11, and 12, and being bolted or otherwise secured to the frame A, as shown in Fig. 50 1. The head has openings B to receive the plunger which is held concentrically therein by set-screws B, so that the holes do not have to be dressed out smooth and to just the size of the plunger, but may be considerably larger than the plunger and as rough as they come from the mold. This plunger has a notch or recess, B, in one side, to receive an arm, B pivoted at B to the head B, by which the plunger is held in its lower position, as more fully described in the operation of the machine. When the arm is released it is pulled back out of engagement with the plunger by a spring, B (see Figs. 2 and 8,) that connects its free end to the head B. To give a bearing for the set-screw B that is opposite the notch B in the plunger,we place a. plate or strip,B (see Figs. 1, 6, 7, and 8,) in the upper hole or opening, B", beside the plunger,whieh gives a long bearing for this screw extending over the recess B gwhen the plunger is in its upper posit-ion, as shown in Fig. 6. This plunger is raised to its upper position by means of a treadle, B", to which it is connected by a rope, B passing over a pulley, B, secured to one side of the frame A, as shown in Figs. 1 and 3. The treadle is pivoted at B to the lower part of the frame A.

D represents the mold of the machine supported between the vertical parts of the frame A. It has end projections or flanges, D, which are grooved, as shown in Fig. 9, to receive cleats A, secured to the frame A. The mold can thus have a vertical movement, for a pun pose hereinafter specified, and its upward and downward movements are limited by stop projections A on the cleats A, against which the flanges D strike, (see Fig. 5;) but this movem ent could be arrested by other suitable means.

I represents the simple lever pivoted'at 1 to the frame A, as shown in Figs. 1, 4, 5, 11, and 12, by means of gudgeons I thereon fitting in boxes A secured to the frame A. It has extensions 1. beyond the pivot-points that are con nected to the plunger 0, near the pivot-point, by links J, the lower ends of which have slots J, to receive a pin or red, J passing through .the lower end of the plunger, its ends entering grooves in blocks A, secured to the frame A, (see Figs. 5 and 10,) thus guiding and hold- 7 ing in place the lower end of the plunger. The {00 upper end of the plunger is held in place by the mold.

L represents a compound lever when acting in eonj unetionwith the extensions 1 of the lever I. It is fnlcrumed on a bracket, L, secured to the frame A. (See Figs. 11 and 12.) It has an extension, L", to which is pivoted a bar, N, having a shoulder, N, to engage a pin or rod, 1, that passes through the outer ends of the extensions I. (See Figs. 4, 11, and 12.) At the proper time the bar N. is pulled over to engage the notch N with the rod or pin 1', by means of a weight, N con necte d to the lower end of the bar by a rope or cord, N passing over a pulley, N, securedto the frame A. (See Figs. 11 and 12.) This bar is pulled back at the proper time to disengage the notch from the pin, by means of a spring, N connecting its upper part to the lever L. (See Figs. 2 and 12.) When the brick is pressed, as shown in Fig. 12, it is removed from the mold by first pulling the free end of the block B back, disengaging it from the plunger B, and then pressing down on the outer end of the lever I, (which will start the upward movement of the two plungers and brick,) until notches O in bars 0, pivoted to and depending from the lever I, engage beneath a pin, P, in a bar, P, connected to the lower end of the plunger 0 by a pin, P, and pivoted by its outer end to the frame A by means of a U-shaped rod, P (See Figs 1, 2, and 3.) As soon as the notches have engaged with the pin 1?, the outer end of the lever I is raised, lifting the plungers until the brick is removed from the mold. The lever is then released, and the plunger 0 falls to its lower position, being prevented from falling too rapidly by a counterbalance-weight, T, connected to the lever or bar P by a rope, T, passing overa pulley, T (See Figs. 1, 11,

v and 12.) In case the plunger should stick and not start this downward movement, it is started by raising the lever L from the position shown in Fig. 12 to that shown in Fig. 11, (a position it has to be placed in before the next brick is pressed,) when the end of the extension L, which has a friction-roller, L", strikes the outer end of a clevis, U, pivoted by a pin, U, to bar P, and held from moving downward by apin, U, passing through the bar P beneath the clevis. The free end of the clcvis will rise to let the projection L pass 011 its upward movefirst filled with dirt and the upper plunger is then dropped, by releasing the treadle B", into the mold, striking the dirt with a heavy blow, compressing it, and this is quite a valuable point in the machine. The next thing to be done is to force the block B into the notch B of the plunger B, thus locking this plunger from upward movement when the lower plunger, 0, is raised, which is the next thing to be done. The first part of the movement of this plunger is effected by depressing the outer end of the simple lever I. When this lever reaches the position shown by dotted lines, Fig. 12, the weight N pulls the bar N over and engages the notch N with the pin 1.

The outer end of the compound-lever is then depressed until the brick is completed, which is thus done under an exceedingly high pressure. During the pressing of the brick by the plunger 0 the mold is moved upward, as described, and thus we get as much pressure on the brick from above as below. When the brick is completed the various parts occupy the positions shown in Fig. 12. The next thing to be done is to pull the block B back out of the notch B, which allows the plungers and brick to be raised, which is done, the first part of the distance, by depressing on the outer end of the lever I (as soon as this is commenced the spring N pulls the bar N back and disengages the notch N from the pin I) until the notches O of the bars 0 engage beneath the pin- P in. the bar P, and then the outer end of the lever I is raised, thus lifting the brick out of the mold by a quick movement, and just as the brick is out of the mold the lower curved ends of the bars 0 come against a rod, V, secured to the frame A, which causes the bars to be forced back, disengaging the notches O from the pin P, allowing the plunger 0 to fall to its lower position, and thus the operation goes on. As soon as the brick is removed from the mold, the mold drops to its lower position. As soon as the plungers and brick are raised until the plunger B is above the mold, so that it can be raised without causing a vacuum in themold, it is raised away from the brick to its upper position by the treadle B. When thebrick is finished, the weight N rests upon a support, so that the rope N is loose, allowing the spring N to pull the bar N back, as stated. The frame A is strengthened by tie-rods A.

We claim as our invention- 1. In a brick machine, an upper plunger adapted to drop into themold and to be locked therein, the lower plunger adapted to be moved toward the upper one, and the mold adapted to be moved upward by the friction of the clay and the lower plunger as the brick is pressed, substantially as and for the purpose set forth.
