UNITED Saulrras IMPROVEMENT IN BRICK-MACHINES.

PATENT O i ICE.

HENRY HUGHES, OF'PEK-IN, ILLINOIS, ASSIGNOR OF ONE-THIRDi IS RIGHT TO WILLIAM S. KELLOGG, OF SAME PLACE.

Specification forming part of Letters Patent No. 138,661, dated May 6, 1873; appli l tion filed September 23, 1872. i

To allfwhom it may concern:

Be it known that I, HENRY HUGHES, of Pekin, in the county of Tazewell and in the State of Illinois, have inventedan Improvement in Brick-Makin g Machines; `and do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the annexed drawing making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure l represents a sectional elevation of receiver for clay, with view of the working apparatus below; Fig. 2, a vertical end "view, partly sectional; Fig.' 3, horizontal section of halfl of the receiver B, the other half being removed to exhibit the platform for the molds.

This invention relates to the reciprocating frame of a brick-machine, having dogs or claws constructed and 'arranged to feed the molds automatically from two ormore chambers to the receiver, in combination with the longitudinal slots of a platform; also, to the operating mechanism for accomplishing the above, as will be hereinafter more fully explained.

One of the forms in which I construct this machine is as follows: A A A A represent a stout square frame, in the upper part of which is the clay-receiver B-a circular receptaclewhich rests upon the bottom C, which, in turn, rests upon long blocks m m m, which form the sides of the passages along which the brickmolds are propelled. Through this bottom piece C are cut several passages, a a, &c., for clay, which lie in a line across the machine on either side of the shaft Q. Below the blocks m m m, and on which they rest, is a horizontal platform, D D, on which the molds slide, and which projects for some distance on each side or end of theframeAAAA, there bein ga space between this platform and thebottom of the receiverB of a little more than the thickness ofthe brick-molds S S, &c. Four parallel slots, ddd d, are cut through theplatform, which run from end to end, nearly, ofthe same, there being two slots on each side of the shaft Q. In these slots pass back and forth claws or dogs c e e c, which project a short distance above the surface of the platform, and are pivoted or otherwise attached to the oscillating frame E E, which is supported in a groove, f, beneath the platform in either side of the machine. ertical slots in the frame E E retain thecla, e, which are each pivoted above their center f gravity so as to maintain the hook of the e `wabove the platform-surface when not other v se depressed. These, or each pair of these, ola on aside of the machine catch the rear end l f the lowest of a pile of molds, S S, &c.,'in t chamber g, when the oscillating frame E E 1 sses inward and carries one mold (one on ea 1| side of the shaft Q) to a spot directly unde he clay-passages a a, 8vo., and then returl for another. The oscillating frame E E is act ted by a rod, F, pivoted to the under side of e same, and having the remoter end attach n Vto an arm, G, which is set on a horizontali xle pivoted transversely of the lower platfor Z. This arm G is, in turn, connected, by a r1 d, H, with a `second arm, I, which oscillates pon a similarly-pivo ted axle, the middle po ion of which arm is connected, by a rod, K, w` `h a bevel or miter wheel, L, which engages 'th a similar cogged wheel, M, fastened upon `n e outer end of a horizontal shaft, N, running ngthwise of the machine. This shaft carries `=econd bevel or miter wheel, O, which engag with a similar horizontal wheel, l), on th l central vertical stirrer and presser shaft and-terminates in a pulley or wheel, T, which the vmotive power is attached. Sev al holes for the pin for adjustment of motio are pierced through the arms Gr and I. Th stirring and pressing shaft Q, in the center of; he machine, is pivoted in the step x on the lo er platform Z, and above in the cross-piece ci t top of the frame A, carries horizontal radi l stirrers or cutters q q q q on its upper part, ithin the receiver B, and below these, ver, il ear to the bottom G, four or more radial inc` ned arms or pressers, RR R R, consisting of i on or other strong material, shaped like a lol ide, and inclined at an angle which will b t press the clay through the passages a a, 8a and are so arranged that they pass over a; press the clay downward into the molds on at the time a mold is situated thereunder. `l e shaft terminates below in a bevel or mi j wheel, P, which, being engaged with anothe, on the shaft N, receives its rotary mot-ion. 1 1

The operation of this machine as follows:

The clay is thrown into the receiver B, where it is thoroughly sliced and mixed and pressed downward by the inclined blades R revolving with the shaft Q through the passages a wat, &c., which are made smaller than the superficial area of the intended brick and its mold S S, &c. One mold, containing brick-recesses similar in number to the openings a a a, &c., lies beneath each set of openings, one on either side of the shaft Q, and are there deposited successively (on being filled) from the supplychambers g g, in which they are piled one uponthe other ready for removal by the claws e e e c, which move along the slots d d d d in the platform D D, and, passing beneath the molds S S toward the outer end of the machine, by bendin g toward the back part of their inclosing slots, re-erect themselves when the outside edge of the mold is reached. One mold is taken simultaneously from each pile of molds on either chamber g g by the claws which are devoted to that chamber and pile of molds, and propelled along the platform D D between the guides m m m to the point under the passages a a, Src., at the same time that one of the inclined presser blades R R R R reaches said opening and fills the mold; and on the passage of another blade, R, thereover the claws e e, 85e., propel another mold to the same spot, displacing the first one, each, in turn, being filled and propelled to the other end of the platform, the mold last deposited shoving its predecessors before it until they arrive at the opening gf tie machine, where they are removed by all The operation of the oscillating frame, or means of actuating it, have been already described under that head, as Well as that of the stirrer-shaft Q.

The area of the clay-passages a a a, &c., are made smaller than `that of the brick-mold below in order that the clay may pass at once to thel bottom of the mold without removing the coatingof sand from the sides of the same, but is afterward, by the continued pressure of the blades R R, 8vo., expanded horizontally on all sides without disturbing the necessary coating of sand on interior of the mold, so requisite for the proper delivery of the well-shaped brick.

What I claim as my invention is 1. rllhe reciprocating frame E, provided with the dogs or claws e, constructed and arranged to feed the molds S automatically from two or more chambers, g, to the receiver B, in combination with the longitudinal slots d of the platform D, the whole constructed so as to operate f substantially as set forth.

2. The actuating-rodF, crank G, connectingA rod H, arm I, rod K, beveled gear-wheels L M, shaft N, drivin g-wheel T, and beveled gearwheels P O, all combined and arranged to opl crate the stirring-shaft-Q and frame E, substantially as shown and set forth.-

In testimony that I claim the foregoing im provement in brick-machines I have hereunto set my hand this 7th day of September, 1872.

HENRY HUGHES.
