JOSEPH O. FIELD, OF BUFFALO, NEW YORK.

IMPROVED TILE-MOLD.

Specification forming part of Letters Patent No. 54,51 S, dated May 8, 1866.

To all whom it may concern: 4

Be it known that I, JosErE C. FIELD, of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Tile-Mold; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I make a stationary base, b, firmly fastened to a plank or otherwise in the circular shoulders on the surface-one outer, letter k, against the inside of which the outer surface of the outer llask, a, rests, and the inner circular shoulder, letter l, is fitted inside of the core c, and by nleans of these the outer flask and the core are centered, and both are held at the proper distance apart from each other for the tile to be molded between. The space be tween the core and outer llask s honld be about one and one-quarter inch, which is about the proper thickness desired for tile or pipe,

The outer flask, a, is a cylinder, except that one end is flared out bell shape, to correspond to or make room for the flange on the bottom of the core, extending out the thickness of the `tile or pipe, and by means of this shoulder on m, Fig. 3, and the bell shape of the outer flask the socket is formed in the pipe or tile in which to insert the other, or rather one, end of the tile.

The outer llask, a, is madein two parts, being divided longitudinally into two halves, or nearly so, in order that they may be detached from the tile or pipe after being molded and sufficiently set. There are two handles, nearly in the center, one on each side, lettered a n. This llask' is held together by the clasp g g, (shown in the drawings,) or in any other strong manner.

The inner cylinder or core, letters c c,is made with a xed flange, m m, so as to form a socket in the tile or pipe, and has a cross-bar, f, near the bottom, and slight ledges in the outer end to rest the head upon. This head is lettered t' i, and has cross-pieces attached extending to the inside walls of the outer flask, and being thus secured inside of the core, and the crosspieces resting against the inside walls of the outer llask, the core is thus always kept steady and stationary in the center, and the head in the top of the core prevents the material for the tile or pipe from falling therein. rIhis head in the core is loose, so that it may bc turned round readily while packing the material for making the tile or pipe.

I now attach a hopper tothe o'nter flasks, lettered o o, with an apron, p, which is removable at pleasure. The apron rests upon a table where the material for molding is prepared. The material is thrown into the hopper and packed between the outer llask and core until it is full. The hopper is then removed and the cover on the core is also removed, and by means of the two handles 1the outer flask, mold, and core are raised and turned over, end for end, and placed upon some smooth surface or plate, and the inverted end of the mold smoothed, and the ring d d, with the cross-barf, is placed uponthe mold and outer Ilask, and by means ot' a bar, r r, the ycore is raised and removed, or the core Amay first be turned around and thus loosened and then read-ily raised.

What I claim as new is as follows:

1. The removable core-cylinder G, in a mold for making tiles or pipe, as set forth, and for the purpose specified.

2. The fixed shoulder on the bottoni end of the core-cylinder, in combination with the bellshaped bottom of the outer flask or mold, for the purpose of forming a socket in one end of the tile or pipe, as and for purposes described.

3. The use of the circular shoulders or projections on the'surface of the stationary baseplate, in combination with the cover with its cross-pieces on the top of the core, for the purpose of centering and preserving the requisite distance between the core and outer llask or mold in order to obtain a uniform thickness in the walls of the tile or pipe, arranged substantially as described, and for the purposes set forth.

4. The-use of the cross-bars f and c, and the lever r r, for the purpose of starting the cylluder-core, substantially as described, and for the purposes set forth.

5. The adjustable hopper o o, substantially as described,and for the purposes set forth.

6. Molding 'vertically with an adjustable core, C, and the other means herein described.
