ISRAEL HOGELAND, OF INDIANAEOLIS, INDIANA, ASSIGNOR TO HIMSELF AND GEO. I. ANDERSON, OF SAME PLACE.

MACHINE FOR. PRESSING AND MOLDING CLAY INTO TILES AND OTHER ARTICLES.

SPECIFICATION forming part of Letters Patent No. 224,015, dated February 3,1880.

Application filed December 27, 1878.

To all whom it may concern;

Be it known that I, ISRAEL HOGELAND, of Indianapolis, in the county of Marion and State of Indiana, have invented a new Machine for Pressing and Molding Clay into a Variety of Irregular Forms, of which the following is a description, reference being had to the accompanying drawings.

Prior to my invention I am not aware that any machine ever was constructed whereby clay that is mixed in and pressed or forced out of any ordinary tile, brick, or pug mills could be formed or molded into various articles of irregular form as the clay leaves the mouth of the mill.

The object of my invention is to construct the dies at the mouth of a tile, brick, or pug mill so as to permit them to be adjusted to various sizes as the clay is being forced through them, and thus produce articles of clay having a variety of forms, such as coffins, irregular boxes, pipes, and moldings.

My invention consists in the new construction, arrangement, and application of devices, all of which, singly or combined, are deemed essential in my newly organized machine,

.whereby the clay, as it is forced from the mouth of a tile, brick, or pug mill, may be formed into articles of various forms, as will be hereinafter fully described and set forth.

In the accompanying drawings, in which like letters of reference in the different figures indicate like parts, Figure 1 represents an or dinary tile, brick, or pug mill embodying my invention. movable or adjustable dies. Fig. 3 represents a coffin as one form in which the clay may be formed as it is forced through the adjustable dies. Fig. 4 represents alongitudinal section of a tile-mill, showing the manner in which the clay is forced through the adjustable dies,

by which the irregular sides, ends, and bottom of aeoffin are made at one operation of the machine. Fig. 5 represents another form of adjustable dies, by which the irregularlyshaped cover of the coffin is molded.

A DK T represent any ordinary tile, brick, or plug mill, in which clay is mixed and ground to the required fineness, and forced out through Fig. 2 represents one form of the month by means of ordinary mechanical powers, such as are in common use for that purpose, and to which I make no broad claim.

At the mouth of the grinder or press-box K are arranged sliding dies 0 O, which, in this case, are adapted to operate with a lateral motion each way from the center of the pressboX-i. 0., they slide in the grooves 8 below and l above, as shown in Fig. 1. At each side of the press-box, or in any other convenient place, are arranged slides E, which operate in suitable guides, such as are shown at a cl, the slides E being provided with longitudinal grooves b b, that operate on the slide a to prevent lateral motion; and the cleat J is attached to the side of the box K, leaving the space d between it and the base D for the inneredge of the slide E to operate in, thus preventing the slide from motion up or down. The two slides E E are united together by the bar F, so that they travel together.

Immediately under the mouth of the pressbox or grinder is a table, H, which may be made of the ordinary form-c. 0., rollers with canvas cover, or in some other form, so as to form a support for the clay as it is forced from the grinding-box.

Each of the slides E are provided with grooves O, or raised projections, which are designed to conform with the irregular shape of the article that is tobe produced from the clay. The particular form of grooveor guide for moving the dies shown in the drawing is that of each side of a coffin.

Each movable die 0 is provided with a stud and roller, 19 '0, that operate in the groove 0 of the slide E, and the two dies 0 0 are made to overlap'each other, and each die is provided with an opening, P 1?, corresponding to the shape of each side of the coffin and the bottom, as shown in Figs. 1 and 2.

When the slides E are closed up so that the bar F is close to the mouth of the press-box, then the rollers a" at each end of the sliding dies 0 are at the head end of the guides or grooves U, and the side openings, P, of the overlapping sliding dies are as close together as they are designed to go by that pattern of groove or guide 0 in the slides. When the I slides E E and the bar F move forward the.

dies 0 O gradually open to the Widest part,

and then close as the rollers rapproach theother end of the guide or groove 0. Thus the movable dies are permitted to open and close as the slides E E move to or from the pressboX, and form a means of forming clay into irregular objects.

The cross-bar F may be provided with a pattern-block, G, that can be used for forming the front end of the first coffin, as shown in Fig. 4.; or it may be dispensed with, and the clay that forms the end of the coffin may be cut off at the required taper. The block it may also be inserted in front of the sliding dies 0 when the-coffin is of full length, and held in position by the swinging block R while the clay is forced between the block a and dies 0 O to form the other end of the coffin, after which the block R, which is attached to the hinged arm W, is to be turned up and the block a be removed, after which the end of the coffin may be cut from the clay in front of the dies and removed for baking.

The movable dies shown in Fig. 5 are designed to lap by each other, the same as the dies in Fig. 2, and are provided with curved openings 1?, that conform to the shape of the coffin-lid. The dies are opened and closed by a patterirguide formed in the slides E, similar to that shown in Fig. 1, whereby the dies are opened and closed and the irregular form of the cover produced.

The operation of m y new machine is as follows, to wit: The sliding dies 0 0, having the required shape ofopenings to form the article desired, are first placed in the slide-grooves 8 Z; then the slides E E, having the guide or groove 0 corresponding to the irregular form of the article to be produced, are arranged to operate in the guides at d. The slides E E and bar F are then moved up close to the mouth of the pressbOX, and the clay is then forced through the variable opening I? I? of the movable die. As the clay comes in contact with the bar F the slides E E are forced away from the dies, either by the clay or mechanical devices, (not shown,) and at the same time the dies 0 O are gradually opened and closed by the rollers 4" moving in the guides C until the slideE has reached the end of its stroke. Thus the clay is made to conform to the variable opening in the dies, and the front end, sides, and bottom of a coflin are produced of the desired shape. The block a may then be introduced in front of the dies, and held there by the block R until the clay is forced into-the space between the block a and dies 0, thus forming the end of the coffin, which is separated from the clay next to the dies by cutting at the line m, Fig. 4, when the coffin is ready for removal. The projecting rib i t at the top of each side opening, P, of the dies causes a nice groove to be formed along the upper edge of the sides of the coffin to receive packing when the cover is placed therein, thus providing a means of making a tightjoint.

It will be seen from the foregoing that my new machine is capable of making an endless variety of irregular clay devices by simply varying the style of the openings in the dies and the guide 0 of the slides, and for irregular moldings the column of clay mayrun out to any desired length required.

In making some irregular devices it may be necessary to arrange more or less adjustable dies, and to arrange the dieopening guideslide in different ways from that shown in the drawings, in order to move the die to correspond with the irregular form of the work produced. 1

What I claim as new, and wish to secure by Letters Patent, is-
