BRICK OR TILE DIE.

SPECIFICATION forming part of Letters Patent No. 331,391, dated December 1, 1885.

Application filed June 30, 1885. Serial No. 170,287. (No model.)

To all whom it may concern:

Be it known that I, JEssE L. FRIEND, acitizen of the United States, residing at Perrysburg, in the county of Miami and State of Indiana, have invented certain new and useful Improvements in Brick and Tile Dies; and I do hereby declare that the following is alfull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective View of my improved die; Fig. 2, a transverse section thereof, and Fig. 3 a detail plan view of one of the die-sections with the packing partly broken away.

The present invention has relation to certain new and useful improvements in brickdies for attachment to a tile-mill, or any machine that forces tempered clay into a mold or through the same, the clay being forced through upon a platform or belt movable as the deposit is made by passing through the die and afterward cut into brick or tile lengths by a wire or other device usually employed.

The invention consists in the details of con struction, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings Ihave shown the die as constructed of three independent sections, A B 0, although a greater or less number may be used, as found desirable. Each section is divided into any preferable number of openings by transverse partitions a, and the sections are formed with perforated lugs 5, through which pass headed screw-bolts c, the screw-threaded ends thereof receiving the nuts d. This is one of many means that may be employed to securely fasten the several diesections together, and therefore I lay no claim to any special means. The die-section A is provided with a plate, D, for convenience in attaching the die to the machine by bolts, clamps, or other suitable means. Each section of the die upon its contacting face is formed with a groove, 6, extending around it for the passage of thelubricating-liquid, which is introduced through the pipes f, the same communicating with the grooves in any convenient manner. Communicating with the groove 6 are small grooves or channels 9, extending out through the inner Walls ofthe openings E, and between each section is placed a packing of felt or other suitable material, as shown at F. The water is introduced through the pipesf, and fed to the die from a reservoir, and as it passes through the pipes it escapes through the felt packing F, between the sections, and also at the corners and sides through the channels 9. By this means water is furnished all around the die as a lubricant to the clay passing through, and by the channels g at the corners of the die-sections a perfect angle or corner is made to the brick.

The felt packing F, which is interposed between the die-sections, may be removed and replaced by new packing when two much worn, or so stopped up or puddled as to prevent the proper amount of water filtering through.

The side walls of the openings E in each diesection are flaring, as shown more clearly in Fig. 2, .forming a decrease in the size of the openings, which is continuous from one section to the other, thus effecting a gradual compression of the clay in passing through the die from section A to section 0 without any repeated motion, but by a continuous pressure, which acts uniformly. The flaring walls of the openings E present an offset or shoulder, h, upon which rests the inner edge of the packing F. These offsets or shoulders it serve the further purpose of p reventing friction throughout, as in passing from section A toBthe compressed clay does not touch the section B until it is near the middle, from which point it is further compressed until it passes through the section, when the clay passes in like manner to the die-section 0, receiving final shape and finish.

The felt packing F, being interposed between the die-sections and connecting with the grooves e and chambers more efiectually and thoroughly lubricates the die throughout, and especially in the center.

The offsets or shoulders h protect the felt packing from wearing, as it forms no part of the sliding surface with which ithe clay comes in contact.

The method of lubrication, also the progressive condensation of the clay, is as equally applicable to tile dies or machines 5 and I therefore do not desire to limit my invention to a brick-die.

The offsets or shoulders and the tapering openings through the die which relieve the pressure on the clay as it passes from one of the die-sections to the other leave space by which the lubricant is freely distributed on the face of the die. 7

Any packing of cloth or felt that is sub- 10 jected either to a direct or sliding pressure quickly becomes worn, and requires frequent renewal, and especially when sliding on such surface it has a tendency to puddle the same, thus rendering it more difficult for the water to percolate through, which objections are entirely removed by the offsets or shoulders and tapering form of the openings in the die.

what I claim as new, and desire .to secure by Letters Patent, is-

1. A die for brick, tile, or other clay-worko ing machines, formed in sections detachably connected together, each section having a groove for the lubricant, a packing interposed between them, and an offset or shoulder formed by the increased width of one of the 35 contacting faces of the die-sections, substantially as and for the purpose specified.

2. A die for brick, tile, or other clay-working machines, consisting of twoor more detachable sections, each having a central groove 0 and a series of transverse channels communicating therewith, packing interposed between the sections, and offsets or shoulders formed by the increased width of one of the contacting faces of the sections, substantially as and 5 for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JESSE L. FRIEND.
