'To alltu'hlom it may cortcern': l y y.

Be 1t known that I, Crans CHAMBERS, 'J1- of Philadelphia, in .the county of Philadelphia aud'State'fof Pennsylvania, have in'vented a` new anduscful Improvement in Brick-Making Machines; andI do hereby dec-lare the follow-v ing Ito be a full and'correct description of thel same, reference `being had to theaceo-lnpanying drawings, in which- Figure l is a side elevation of a belt embodying my improvements, the upper hinged clamping-frame thereof being thrown up in a vertical position.` Fig. 2 is avertieal longitudinal v central section ofthe sanie,with the said hinged clamping-frame resting in its proper position on the lower inain frame, Fig. 3 is a plan of the main frame, the upper clamping-frame v being removed, anda portion of the apron passing over the 'rollers in the lower frame broken away, so as to exhibit the grooves in said rollers.

This invention relates to Vcertain improve` ments in brickmaking machines patented 4by me on the (ith day of Oct-ober, 1863, its object being that the bar of clay issuingfrom the forining-die ofa machine operating on the principles of my said patent shall travel in astraight line and with an equable motion to the severing-knife, thuseausing it to be always cut in' to uniform lengths and perfectly square and true, and preventing it from being moved latcrally or slipping back and forth longitudinally while passing from the die to the knife;

and to this end my invention consists in the "employment, in the construction of the regu- :is weights to press the lower side of their apron or belt down against the bar of clay, passing between said apron and-thc apron in the lower franie upon which the bar of clay is supported.

Corresponding partsin the several figures are represented by similar letters.

A marks the lower mainframe, constructed ofthe upper and lower rails, (t t and?) b, and upright pieces or legs c' r", which are rigidly secured togetherbymeans of diagonal braces, f

.cross-piece, `and screw-bolts.

B indicates a largepulley,y in the cen-ter lof the face of which is "eut a groove for the receptionof projecting buttons, secured vto the -ini `ner side of theapron D for the purpose of retaining said apron in the iniddleof said p11l ley While in motion thereon. The pulley B is y fastened to an' axle rotating injournal-boxes secured to the outer sides of the legs e" c" of frame A-` i C designates a tension-pulley iXed upon'an axle revolving in journatboxes fastened tothe lower extremities'of the pendants e e, and is 4 designed to give the required .tension to the apron-D, against which it presses, it being sit-l uated a shortdistance from the pulley B, and

directly under the lower portion off the said apron, as shown in Fig. 2. The pendants e e 1 are secured at their upper extremities rto a cross-bar, having its ends proj 'ecting through loops g, screwed to the outer sides ofthe railsl a a of frame A, and projecting downward at acute angles with the said upper rails of the frame A.

D designates the endless apron, passingaround' large pulley B, over tension-pulleys C, around grooved rollers E and end roller, F, revolving upon an axle having itsbearingsin journal-boxes secured at the end of frame A, opposite that to which pulley B is attached.` This apron is supplied on its innerside with Va series of projecting buttons, f f, placed at suitable distances apart, and entering the grooves It in rollers E for the purpose of keeping the said apron in a perfectly straight line on said rollers and roller F, thereby carrying the bar4 of clay in a straight line from the die to the severing-knife. These projecting buttons ff may be placed at equal distances apart, and,v

instead of running in a continuous groove in the end roller, may gear into distinct recesses made to receive them in the periphery of the wheel, which is geared to the Isevering-wheel of thebrick-n1achine, thus communicating a positive'motion from the lower belt to said severing-wheel.

E E indicate a series of rollers, having the grooves 71l in the middle of their length, and

rotating in apertures in the sides of the rails a of the'fraine A, the ends of said rollersbeing reduced so as to enter the said.V apertures, and keep them in position in said frame.

G designates the upper frame, 'which is4 hinged to one side of the fra-me A, and cousists of the side pieces, i i, which are rigidly braced together a suitable distance apart by the screw-bolts and nuts j and supplied with the slots k k, as shown in Fig. 2.

H is another series of rollers, similarly constructed to therollers of the series marked E, but .Without thegrooves h. Their ends enter the slots k and slide vertically therein. These rollers 'are made heavy, in order to press the apron or belt L, upon which'they rest, down upon the bar of `clay, passing between it and the apron D, thus assisting the said apron D in carrying the clay perfectly straight to the severing-knife, and preventingits slipping` back and'fortli longitudinally on said apron.

By reason of. their insertion in the slots kin the sides of the frame G,the weighted rollers H readily accommodate themselves to variations in the thickness of the bar of clay passing1 bel heath them.

L is a' lielt passing around the pulleys P Q, hung' to the ends vof the frame G and under the sliding weighted rollers H, its office being to distribute the pressure over the surface of the bar of clay and prevent the clay adhering to the rollers.

Patent, is-

l. The off-bearing or regulating belt or apron of a brick-machine, provided with the projections or buttons ff ou its inner side, and Workiu'g over rollers having grooves or depressions in their surfaces' for the passage or reception of' said buttons, as and forthe purpose described. 2. .The combination and arrangement of the hinged frames A and G1 with their respective belts D and L and self-adjusting rollers H, constructed and operating as stated.

The above specification of my said invention signed and witnessed at Philadelphia this 26th day of Januaiy, A; D. 1870.
