BRlCK-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 243,505, dated June 28, 1881.

Application filed April 15, 1881. (No model.)

Io all whom 'at may concern:

Be it known that I, GEORGE OARNELL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Brick-Machines, of which the following is a specification.

My invention relates to certain improvements in that class of brick-machines in which the clay is forced from the filler-box by aplunger into a series of molds beneath said tillerbox, my improvements relating to details in the 'construction of the machine, too fully described hereinafter to need preliminary expla nation.

In the accompanying drawings, Figure 1, Sheet 1, is a perspective View of the machine; Fig.- 2, Sheet 2, a longitudinal section of the same; Fig. 3, Sheet 3, a sectional plan ou the line 1 2, Fig. 2; Fig. 4, a sectional plan on the line 3 4, and Figs. 5, 6, 7,8, and 9, Sheet 4, detached views of parts ofthe machine.

A is the frame of the machine; B, the vertical clay-box; D, the filler-box on one side' of the same; and E the main driving-shaft, passing vertically through the center of the claybox, and rotated by power derived from any adjacent shaft. Y

To the filler-box D is adapted a plunger, a, rendered vertically adjustable on a rod, b, by means of a nut, b, adapted to the threaded lower end of the rod and bearing on the top of a hollow lug, 112,011 the plunger. The rod b is adapted to a guide on the clay-box, and is connected by means ot' a link, c, to an arm, (l ,on a rock-shaft, d, the latter being adapted to bearings on the frame A, and having a forked arm, d?, a pin, d3, which engages with a slot in a rod, e, lullig to a `yoke, F, which slides in guides e on the top ofthe frame, and is acted upon by an eccentric, F', on the main shaft E, so that as said shaft is rotated a vertical reciprocating movementwill be imparted to the plunger a. p

The yoke F consists of end bars,ff, and connecting-rods f f', and in order to permit the movement of the eccentric F without imparting any lateral movement to the yoke, the said eccentric is adapted to act upon the end bars, f, of the yoke only, and the latter have segmental recesses f2 formed in them to prevent the eccentric from becoming jammed between it rotates. (See Figs. 1,

effected by manipulating a lever, G, hung to the arm d2, the short arm of this lever having a projecting pin, on which the rod c rests.

The shaft E has within the clay-box the usual tempering blades or arms g and two pressers, H and I, the presser H being located immediately above a slotted partition, H', in the clay-box, andthe presser I being at the bottom of said box. The presser H has curved plates h, which, as the presser revolves, tend to force the clay downward through the slots h in the partition H. Stones or other hard particles which are too small to interfere with the formation of the brick or the operation of the pressing mechanism will be forced through the slots h with the clay, but larger stones or other foreign matters will be carried around by the blades lz, as they cannot pass through the slots. In order to dispose of these larger particles and prevent them from accumulating on the top of the partition I make the slots in the latter in the form of scrolls, there being in the present instance in the partition four independent scroll-slots, terminating, respectively, in the four corners of the clay-box, as shown in Fig. 3, so that stones, under the inuence of these scroll-slots,will,as they are carried around by the blades h, be thrown outward, and will finally be deposited in one or other of the corners of the box, out of the path of the blades h, the accumulated stones in the corners of the box being removed at intervals by the attendant.

The presser I, Fig. 4, consists simply of a camblade, adapted to force the clay through a side opening, t', in the clay-box and into the filler-box D, where it is acted upon by projections a' of the plunger a, and is forced through the grating D' at the bottom of the filler-box into the series of molds m beneath said grating. The molds m are preferably of a character similar to that described in a separate application led by me on the 9th day of February, 1881, although my machine is adapted IOO for use in connection with any mold having a series of openings side by side, so as to form a series of bricks at each operation of the plunger.

bars a', which are adjustable in respect to the frame of the machine, in order that a proper joint between the tops of the molds and the bottom of the filler-box grating D' can always be maintained, the adjustment in the present instance being effected by set-screws n2. When one set of molds is filled it is pushed from beneath the ller-boX and onto a platform, J, by the action of a fresh set of molds on a carriage, K, the latter being adapted to suitable guides in the bars a', and being actuated by a cam, L, on the shaft E. As soon as the new set of molds is adjusted to its place beneath the filler-box the carriage is retracted by the action of the weight L, and a fresh set of molds is slipped laterally onto the said carria ge priortoarepetition of theoperation. The

cani L acts upon a spring, p, on the carriage K, as shown in Fig. 7, this spring bearing upon a central set-screw, 19 but being free to yield at each end, so as to lessen the shock caused by the first con tact of the cam L, the adjustment ofthe setserew p serving to govern thelimitof movement of the carriage K by the cam L. so that the depositing of the molds m exactly under the center of the filler-box is insured. As the molds are pushed from under the filler-box the bricks are leveled by the action of the plate s, which is let into the filler-box grating, and forms part of the bottom edge of the same. (See Fig. 8.) It will be observed that this cutting-plate s overhangs the outer edges of the molds, so that when said molds are pushed from under the ller-box the plate commences to act upon the surface of thebrick at some distance from the edge ofthe same, and there is not that tendency to tear the clay away from the end of the mold which exists when the cutting-plate commences to act upon the eXtreme edge of the brick. As the molds pass from under the filler-box the upper faces of the bricks are moistened by a stream of water from a pipe, t, communicating with a reservoir, t', at the end of the filler-box, and the moistened faces of the bricks are then smoothed by the action of a scraping-plate, w, secured to the side of said filler-box.

The molds m rest upon rollers n carried by By providing the plunger a with projections a', adapted to the openings in the grating D of the iiller-box, almost the entire body of clay in the filler-box is forced therefrom into the molds on the downward stroke of the plunger, so that there is not left in the filler-box or grating a large mass of clay, from which the bricks must be forcibly separated on pushing the molds from beneath the filler-box. The tearing of the clay from the molds and the formation of defective or imperfectly shaped bricks is thus prevented.

I claim as my invention- 1. The combination of the shaft E and its eccentric Fl with a sliding yoke, F, having recessed end bars, f, as set forth.

2. The combination of the plunger-rod b, rock-shaft d, having arm d2, with pin d3, the yoke F, the slotted connectingrod e, and the lever G, hung to the arm di", and adapted to elevate the rod c, as set forth.

3. Thecombination ofthe clay-box, the shaft E, the presser H, and the partition H', having scroll-slots h', as set forth.

4. The combination of the mold-carriage, having a spring, p, with the operatingcam L, adapted to act upon said spring, as specified.

5. The combination of the operating-cam L with the mold-carriage K, its spring l), and set-screw p', as set forth.

6. The combination of the molds with a ller-box, having on its under edge a cutterplate, s, adapted to overlap the outer edges of the molds, as set forth.

7. The combination of the filler-box with the sprinkling-tube and scraper-plate, whereby the surfaces of the bricks are smoothed as the molds are moved away from the ller-box, as specified. f

8. The combination of the filler-box, its grating D', the molds, and mechanism for moving the molds beneath the box, with the plunger a, having projections a', adapted to the openings of the filler-box grating, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE GARNELL.
