Be it known that I, WILLIAM E. DAMON, of

My invention relates to certain new and Figure I is a top view. Fig. II is aside Fig. III is an end Fig. V represents a Fig. VIII represents a plan and end Referring to the drawings :1 represents the I provide for mixing the clay an upright The mixer is preferablyactuated by means 5 represents the bottom of the receiver hav- 7 represents an aperture extending through 8 represents an elongated casting having rises and falls it assumes a rocking movement. (See Fig. III.) As. the beater is raised the plastic clay will pass through the aperture 7 into the aperture 11 in the casting 8 and extending over removable dies 14 set in the bottom plate 5 of the receiver, said dies having cable passing over a pulley secured to the side of the receiver under a pulley 21 journaled near the bottom of the receiver, through the lower end of a lever 22 at 23, thence around a pulley 24 and having its opposite end secured to one end of a bar 25 which feeds the molds.

26 represents cams onthe sweep 4 which as the sweep revolves come in contact with an anti-friction roller 27 on the upper end of the lever 22, said lever being pivoted to the side of the receiver at 28, the cams causing said lever to rock forward (see Figlll). the lower end of the lever traveling backward and cansing the cable 1 9 to raise the beater, as shown in dotted lines Fig. 1Il.- As the cams pass out of contact with said lever the heater is permitted to fall and presses the bricks, the falling of the beater causing the lever 22 to rock backward into its normal position, as shown in central dotted lines Fig. II ready to be again actuated by the following cam.

29 represents pins which limit the back ward movement of the operating levers when in their working position.

30 represents a rack suitably supported beneath the clay receiver and along which the molds 16 travel, the molds being placed on the rack through an aperture 31 in the frame of the same. 32 represent a lever similar to lever 22 and pivoted at 33 to the opposite side of the receiver.

3st represents a cable having one of its ends connected at 35 to the lower end of the lever 32 and its opposite end secured to one end of ICO the feed bar 25. The main portion of the feed bar rests upon the side barsof the rack 30, andis provided with a shoulder 36 which extends down between said side bars and always remains at the rear of the last mold placed upon the rack.

37 represents a spring-which serves to return the feed bar 25, and the lever 32 back to their normal position after said lever has bee; released by the cam on the sweep.

38 represents an anti-friction roller on theupper end of the lever 32 with which. the cams on the sweep come in contact as the same revolves. 1

In operation, as the cams 26 come incontact with the anti-friction rollers 27,38 the levers 22, 82, are rocked forward,- the lever22 with its connecting cable 19 raising the beater; 12, upward and at the sametime saidlevers and their connections force the feedbar 2 5 forward the width of one of t-hemolds 16, thus forcing out from beneath thedies aimoldfull of bricks and placing an emptyniold. in its place ready for the next series of bricks which are formed by the beater as it drops after the lever 22 is released by. the cam,- the lever 22 i being forcedback into itsnormal p'osition by theweight of the beaterand the lever32tandthefeed .bar 25 being returnedtotheimnorinal position by means of. thespring 37.

In order to first grind and mix the: clay before forming the bricksI remove the pins 29..

and press the levers 22, 32 back ward as showm in dotted lines Figs. II and IV which'permits the cams to ride freely over the samewithoutactuatingthem. V t The beater not only serves to form! the bricks, but also assists to workvthe clay into a proper consistency. The excess claynot pass ,ing through the dies at each drop of the beater is forced by the same back into the receiver and is thus thoroughly mixed and. worked.

I do not confine myself tothe cableshown for raising the beater as its equivalent; such for instance as a sprocket chain,might be used, without departing from the spirit of my invention.

I claim as my invention 1. In a brick machine, the combination of a suitable clay receiver, a rocking beater hinged to the receiver, a lever pivoted to the receiver, means for rocking said lever, and a cable for connecting the beater with the lever, substantially as described and for the purpose set forth.

2. In a. brick machine, the combination of a suitable clay receiver, a beater connected with the receiver, levers pivoted to the receiver, means for rocking said levers,a feed bar for feeding the inolds,means for connecting said feed bar withthe levers, and means for connecting one of said levers with the beater, substantially as described and for the purpose set forth.

i 3. In a brick machine, the combination of a-clay receivelga beater and dies forforming the brick, a. pivoted lever for raising ithe beater, a sweep and cam for rocking said lever, a bar for feeding the molds, a cable hav-. .ing one of theends connected with the beater,

engaging suitable bearing pulleys andthe le- -ver, and having its opposite end secured to the feed bar, substantially as described and for the purpose set forth.

4. In a brick machine, the combination of a clay receiver, a beater anddies for forming the brick pivoted levers for operating the beaters tan'tl feed bar, means for rocking the same. a feed bar25 for feeding the molds, means for connecting the levers with said feed nbar, and a spring for returning said feed bar and one' of said levers to their normal position,substantially as described and forihe ipurpose set forth.
