To all whom it may concern:

Be it known-that I, DANIEL E. REAGAN, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State. of'.Ohio, have invented certain new and useful Improvements in 'Brickmaking- Machines; and I do hereby declare the fol- "lovfvingt'o be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My-invention relates to an improvement I in'brick making machines.

Heretofore in the manufacture of paving bricks or blocks having projections on one or more facesfor holding them apart so as to permit the cement, grout or other filler commonly used for bonding purposes, to be readily poured-or inserted between the bricks or blocks, and which also, facilitate the laying of saidbricks by'=keeping them alinement, these projcction's'. .have been formed by repressing the bricks, and also by rollers or other pressure devices anpliedtet-hc lav molded by the die. These devices are obfjectionable because of thecost of repressing,

quent application of pressure to the clay; bardeforms the clay'bar, and unless the pressure be considerable, the clay will not be forced up from the unconfined clay bar into the recesses in the roller or other pressure device, 'so as to form the projections, regular in size and. shape.

The objcctiof my invention is to provide a roller which forms one-side of a face of the die, so that the clay as it is forced through the die will be forced positively into any recesses in the latter.

A further object is to provide means for rotating the roller section of the die at the same speed of travel ofthe clay bar through the die, so that there will not be any dragging or shearing strains on the said lugs or projections.

With these and other objects in View my invention consists in the parts and combinations of parts as will be more fully delongitudinal section through one of the diesi 'F 1g. 3 1s a View in front elevation of the die plate carrying the roll and driving gear I forsame; Fig. 4 is a plan view and Fig. 5 a view in end elevation of the same.

In the drawings ,1 have shown a double stream die for making two clay bars at a time, but I would'ha've it understood that my improvement is equally applicable to a smgle d1e machine.

1 represents the head of a brick making through-which the clay is forced, and 2v is a gate secured to the outer open end of the head 1 by the hinges 3 at one side and by machine, to which the die is attached and size, shape arid construction except'that the ,top is open to receive the roll 5, which latter I forms the ton of the. die. while tbesides and tom and side walls 6 and 7 respectively,

formed integral with each other and also with the die plate.- The sides or side walls 7 of the die are connected at'their outer ends by the integral cross member 8, and the side members are provided attheir top with the:

semicircular bearings 9 in which theshaft v 10 having the IOllS'fi thereon, are mounted and in which it is secured by the removable half bearings 11, secured by screws to the upper edge of the sidewalls of the die. The rolls 5 may be integral with the shaft or made separate therefrom and secured thereto by keys or otherwise. The roll or rolls are so located with respect to the head 1 of the machine, that the shape of the clay bar or column, is not fixed or complete until it engages the roll, so that the pressure against the clay which forces the latter out through the die, will force it up and into contact with the roll, thus causing the clay to enter and fill the recesses 12 in the rolls and produce corresponding projections, on I i the upper face of the clay bar or column, while the smooth portion of the surface of the roll acts as a wall for the die. The top i wall of the die, or the lower face of cross bar 8 'is elevated sufiiciently so as not to engage theprojections on the clay bar orcolumn.

The rolls, or roll shaft 10, is provided at may be used for shaping two faces, but I i one end with the pinion 13, which meshes prefer one. The lugs orprojections 25 are with the large gear 14, secured on shaft 15 preferably curved as shown and are so lo-' Which' is mounted at one end in bearing 16 cated that each brick or block formed will 5' formed in a side wall 7 of the die, and at the have a plurality of projections on one side,
