BRICK-MAcl-HNE.

SPECIFICATION forming part of Letters Patent No. 631,630, dated August 22, 1899.

Application filed November 19, 1898. Serial No. 696,871. (No model.)

To all whom it may concern@ f Be it known that we, J AMES GARRETT and JAMES WELCH, both of Monaca, in the county of Beaver and State of Pennsylvania, have invented a new and Improved'Brick-Machine, of which the following is a full, clear, and exact description.

The object of the invention is toprovide a new and improved brick-machine more especially designed for working soft clay and arranged automatically to -cut off and remove the surplus material from the top of the molds during the passage of the latter from the machine.

- The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of a brickmachine having the improvements applied. Fig. 2 is a perspective view of the improvements detached from the machine, and Fig. 3 is an enlarged transverse section of the table on the line 3 3 in Fig. 2.

The upright brick-machine (illustrated in Fig. 1) is provided with the usual framework A, in which reciprocates a plungerB, connected by a pitman C with a rcrank-arm D, rotated in the usual manner to impart a reciproca ting motion to the plunger B and press the material into the molds E', arranged on the under side of the framework A. The means for filling the molds with material and for'pressing the material in place may be of any approved construction, and hence further description of the same is not deemed necessary.

On the discharge side-that is, on the front of the machine and directly over the discharged mold'sE-is arranged a table F, hung at F' on a rod'G, carried by brackets G', attached to the sides of the mold-carrier E. The table F is reinforced at its sides by transversely-extending ribs F2, projecting beyond the inner or free end of said table F to be attached to a tie-rod F3, held on springs II,'sus pended from brackets H', likewise secured to the mold-carrier E. The ribs F2 extend on the outer side of the table beyond the ends of the molds, so as not to come in contact with the material contained in the molds, and on the top of the table F, at the free end thereof, are arranged similar ribs F4, also leading to the tie-rod F3, said ribs being spaced according to the partitions in the molds, so as not to come in contact with the material contained in the molds. The free end of the table F is bent downward and outward, as is plainly shown in Fig. 2, and a receiving-plate F5 is riveted to the end of the table, and somewhat in front of the edge of said plate F5 is arranged a cut-off device I in the form of a Wire held in the ribs F2 of the table, one end of the Wire being drawn on by a spring I', which serves to hold the wire tight across the table and to permitthe wire to yield when striking an obstruction.

From the foregoing it is evident that the table Fis mounted to swing up or down on the rod G, and its free end is spring-supported, so as to permit the table to yield upward. when the filled molds are pushed out of the machine, and the rod forming the cut-oif device I strikes off the surplus material from the molds and causes the said material to pass up the plate F5and upon the table F. Thus when the filled molds are pushed out of the machine by the action of the empty molds in vthe brick-press then the cut-offV device I removes the surplus material from the molds and delivers this material upon the table F, extending over the lled molds.

In order to remove the surplus material from the table, we provide a sweep J in the shapeof a plate set vertically on one end of the table F and adapted to travel over the same, together with a pipe K, attached to the v -sweep and connected by a Iiexible hose K' with a water or other liquid` supply for supplying the table F lwith, water'to insure a proper removal of the material when the sweep J moves over the table from one end thereof to the other. The sweep J .is provided With a bearing J', engaging a guiderod J2, secured in the brackets G"directly above the rod G, so that the said-sweep J reciprocates over the table Fin the direction of said rods G and Jz.- Buffer-springs .J3 are coiled on the guide-rodJ2 next the brackets G', so as to ease the movement of the sweep IOO on nearing the end strokes. The sweep J is pivotally connected at its back by a link J1 with an arm L, secured to or formed on a shaft'L, journaled in suitable bearings on the upper end of the framework A, said shaft also having an arm L2 in the path of and actuated by the crankarm D, connected with the pitman C, as previously explained. On the arm L is arranged a weighted arm L3 for insuring a rapid return movement of the sweep J after the said sweep has been pushed over the table in the direction of the arrow a' to remove the surplus material and push the same over a chute N into an elevator O of any approved construction for conveying the material to a suitable place of discharge. It is evident that after the molds are filled in the machine and the pitman C rises to its first position then the crank-arm D imparts a swinging motion to the arm L2 to turn the shaft L', so as to cause the arm L to move the sweep J forward in the direction of the arrow a' for removing the su rplus material of the last-filled mold from the table F. \Vhen the pitman C is on its downward movement to cause the plunger to ll the next mold with clay, then the crank-arm D releases the arm L2, and the weighted arm L3 now causes a return movement of the arms L and L2 to draw the sweep J back to its previous position, as illustrated in Figs. l and 2. As the iilled molds move out of the machine the cut-oit device l removes the surplus material, as previously described, and as this material passes upon thc table F it is removed therefrom by the next movement of the sweep J, as previously explained.

The free end of the table F is curved downward and forward, so as to press firmly upon the top of the mold and cause the wire I to remove all the surplus material from the mold and cause said material to pass upon the table F.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patentl.
