CLAY-WORKING MACHINE...

' Specification of Letters Patent.

Patented March 20, 1906.

Application filed April 24, 1905. Serial No. 257,188.

To aZZ whom it may concern: Be it known that I, FRANK ALsIP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Clay-Workin Machines, of which the following is a s ec' cation. i

My invention re ates to that class of clay working machines employed .in the making of bricks or bricks and tiles and having a nozzle provided with or forming a die .or matrix, through which a column of clay in a plastic condition passes, such'column ofclay being molded by the die or matrix into the desired form and adapted to becut into sections or bricks in any ordinary and well-known manner.'

It relates particularly to that class of clayworking machines known as brick-making, or brick-molding machines having anozzle provided with a die or matrix integral there'- with or secured thereto throughwhi'c'h the column of clay passes to be out into bricks after emerging therefrom, being first separated into a plurality of columns and then cut into bricks of the desiredsize.

-The principal object of my invention is to rovide a simple, economical, and efiicient rick-making machine.

A-further object of the inventionis to provide a brick-making machine having a nozzle provided with a die or matrix through which the column of clay operated upon passes and provided with means for separating the column of .clay into a plurality of columns as it emerges from such die, or matrix, such column being adapted to be cut into sections of the desired dimensions tovform bricks and the like.

A further object is to provide. a suitable cutter arranged outside the die ormatrix through which the column of clay passes and adapted to be adjusted and supported in operative position to separate the column of clay into a plurality of columns asit emerges or after it emerges from the die or matrix. A further object is to provide cutter mechanism extending across the outside of the mouth of the nozzle or die adapted to out the column of clay emerging from the die into a plurality of columns and adapted to be readily renewed or re laced when broken.

Other and urther objects of the invention will appear from an examination of the draw- .ings and the following description and claims.

The invention consists in the features, com-' sides of'the columns of clay separated andv resting upon-the carrier belt or apron; Fig.

3 a detail view of one ofthe cut'ter-supporting arms; Fig. 4:, an edge view of the cuttersupporting arms shown in Fig. 3, and Fig. 5 a detail view in elevation of one of the cutters.

In the art to which this invention relates it is well'known-that it is very desirable toform a plurality of columns of clay, so that they may be simultaneously cut into sections or bricks of the desired dimensions, thus afiording a great saving of time and greatly increasing the capacity of a machine. In order to accomplish this, machines have been constructed which force the clay through aplurality of dies or matrices or through a die or matrix having a plurality of openings, the o I clay emerging from such dies or matrices into two columns. It is found, however, in practice that the columns of clay thus formed cannot be caused to move at-exactly the same rate of speed, and it is well known that this is essential in order to accomplish the best results. By causing a plurality of columns of clay to "move at the same rate of speed it becomes possible to out such columns intosections or bricks of exactly the same dimensions and by means of the same operation of the cutting device. The cutting may be accomplished in any ordinary and well-known manner. To accomplish. these objects and to overcome the above objections,

instead of forcing the clay through a plurality of dies, so that it emerges from the dies in two columns,I provide a machine adapted to force the clay from the die in a single column and provided with cutter. mechanism adapted to out such single column of clay into a plurality of columns after it emerges from the die. By this means the columns are caused to be produced and to move at exactly the same rate of speed.

In constructing a brick-making machine provided with my improvements I provide a clay-containing cylinder a, forming a receptaele for containing clay to be operated upon and having a concave or tapered member I) and a nozzle 0 secured thereto in any ordinary and well-known manner. The nozzle may be of any ordinary and well-known type. It has a tapered axial passage or opening therethrough communicating with the receptacle for containing the clay and is provided with a die or matrix either integral therewith or secured thereto in any ordinary and well-known manner, forming top, bottom, and side molding-surfaces of the desired form for molding the column of clay d, which is forced through such die or matrix. The die or matrix memher. or members may be of any ordinary or known type, and as these dies are well known in the art it is not deemed necessary to illustrate or describe them here.

My improved cutter mechanism, consisting of a plurality of cutters e and e and cuttersupporting arms f and g, is secured in posi- 2 5 tion so that the cutter extends across the mouth of the nozzle and across the mouth of the die or matrix secured to or formed by such nozzle. The cutter-supporting arms are secured, preferably, to the nozzle by 0 means of bolts 7L and i. The bolts h pass through perforations in the upper and lower cutter-supporting arms, respectively, and each of such cutter-supporting arms is provided with slots 76, elongated transversely of 5 such arms and of the nozzle to which the arms are secured. The cutters e and e are formed, preferably, of wire, having their opposite ends provided with loops Z, which are mounted upon studs m of the cutter-support- 4o ing arms, such studs being preferably inclined backward in the direction of their outer ends, so as to hold the cutter-wires removably in position. The cutter-wire-supporting arms are made of flexible material,

referably tempered steel, being curved or ent sufliciently so that they normally extend outward from the outer surface of the nozzle.

"' When the cutter-wires are attached to these resilient cutter-supporting arms, the arms are pressed inward toward the outer surface of the nozzle and held at a tension by the wires, the cutter-wires being in turn held at the desired tension so as to efficiently cut the column of clay as it emerges from the die or matrix into a plurality of columns each adapted to be cut into sections or bricks of the desired dimensions.

In order to enable the cutter-wires to be readily adjusted, it is only necessary to loosen the bolts h and 'i sufficiently to permit the cutter-supporting arms to be moved transversely of the nozzle or die to the desired position, such movement being permitted by the elongated slot is in each of such cutter supporting arms. The cutters having been adjusted to the desired position, the bolts are tightened and the cutters are held stationary in operative position.

When in operative position, the cutter (2 extends across the outside of the mouth of the die or matrix or the nozzle forming the die or matrix, so that the column of clay emerges from the mouth of the die, and after emerging therefrom it is cut into a plurality of columns by the cutter. The plurality of columns it thus formed passes onto a supporting-plate o and from such supporting-plate to a carrier apron or b elt p, which is mounted upon supporting-wheels q, the supporting-wheel near the nozzle being cambered or of larger diameter at its peripheral center 1 than at its outer edges 8, so as to cause the adjacent side surfaces of the columns of clay to be separated as shown in Fig. 2, and thus prevented from sticking together.

To further insure the continued separation of the columns of clay formed by cutting the column d into a plurality of columns as or after it emerges from the molding surfaces and mouth of the die 1), a sand-box t, which may be of any ordinary and well-known form, is provided and mounted over the column of clay upon a supporting-bracket u. The sandbox is provided. with suitable openings for permitting the sand. to pass therefrom between the separated columns of clay, so as to sand their adjacent sides and the surface of the carrier-apron, so as to prevent the clay from sticking to the apron and also prevent. the separated columns of clay from adhering together. The cutting of the column of clay is performed by forcing the clay throu h the die c, which molds it into a single co umn, and the same power which molds it forces it against the on tter-wire arranged in its path of movement, and thus cuts it into a plurality of columns. The mechanism for thus forcing the clay against the cutter and through the mold may be of any ordinary or known type. The carrier-apron wheels q may be rotatably mounted in bearing-boxes 1 upon standards .2, forming portions of a brick-making machine, which may be of any ordinary and well-known type.
