MOLD FOR ARTIFICIAL STONE.

To all whom it may concern:

Be it known that I, THnonoun V. Ganissr, citizen ot the United States, residing at the city and county of San Francisco and Sta-te of California, have invented new and useful Improvements in Molds t'or Artificial Stone, &c., or" which the following is a specification.

My invention relates to mold-boxes, and particularly such molds as are used in torinin g concrete blocks, bricks, or other like articles.

One of the objects of my invention is to provide a simple, sectionally formed mold, in which are to be made suitable artilticial stones, such as are usually made of a mixture of concrete and other' materials, and are usually reinforced in the ordinary way, with iron rods or wires spread through the plastic material.

Another object is to provide ay mold-box ot' such length that it may be readily divided into separate sections ot` suitable lengths so as to allow the molding of several separate or individual stones or blocks in the one box, and providing means for adjusting the sections into suitable lengths.

Referring to the accompanying drawings, Figure l is a perspective view otl the moldbox. F ig. 2 is'an end view of the same. F ig. 3 is a rear view. Fig. 4 is a front view of the box. Fig. is a cross sectional'view.

In the embodiment of my invention as actually employed I provide a back member or section 2 having on its upper' edge al suitable metallic strip or perforated l'lange 3 which is firmly secured to the back member. This back member is made orsuiiicient thickness, and may be constructed of wood, or other suitable material, so that suitable grooves A may be channeled throughout its length so as to form any desirable ornamentation on the surface of the stone or block to be made.

The mold is particularly useful in the formation of steps, sills, intels, mullions and the like, which are usually made up in large numbers, and of course one article or stone,

such as a step, would be made of the same design.

The bottom member is detachably secured to the rear member by suitable locking screws G, and brace hooks 7, and is provided along its outer edge with a vertical perforated liange metal strip 8. The strips 3 and S project more or less toward eachother Specification of Letters Patent. Patented Sgpt, 28, 1909, Application led October 12, 1908.

and beyond their contiguous members; and the space included between the parts 2 5 and the projecting flanges of 3 8, as shown in Fig. l, forms a mold space to be filled with suitable material which is tamped so as to insure the formation of a solid coirpact mass. The locking screws 6 are preferably rigidly set in the bottom member 5 otl the mold-box, and in assembling the sections the back 2 is slipped over the screws 6 which project from the rear edge of the bottom Suitable locks or locking handles 9 are then screwed up on the screws 6 tightly against the back 2, thus maintaining the back at an approximately right angle to the bottom member. The bracing members 7 are secured at suitable points along the length of the back 2 and bottom 5, and are bent angularly toward each other, and have hooks l0 and eyes ll so that they are intorloeked, and maintain the parts in rigid position when the lilling material is being tamped.

At l2 is shown a removable wall or partition plate adapted to be set transversely across the mold-box at any desirable point, by means of locking-pins 13, insertible through holes la made in the strips 3 and S.

The bottom-plate 5 may be provided with suitable foot-'pieces l5 along its length, and thereby supported clear ot' the ground or platform on which it may be used. Obviously, one of these mold-boxes may be made in lengths, say, of 2O t'eet more or less, and as many ot' the dividing walls l2 as desirable, may be set at suitable points along the mold-box, and when the material is then filled into the mold-box, it will be apparent that a series oit' stones will be formed simultaneously, all having similar shape and of the same mixture.

It will be noticed that the mold is made practically of only two sections, the back Q and the bottom 5, and when it is necessary to remove the molded block or stone from the box, the back 2 is removed by unscrewing the locks 9, and the stone may be lifted from the bottoni 5. An important advantage in this simplicity ot' construction, lies in the fact that when it is desired to make blocks of ditlerent contour or design, it is only necessary to change or replace the back 2 with another having the desired contour, or moldingl groove 4. Manifestly this groove 4 can be made of numerous designs, all of which will lend themselves readily to the molding of the stone. The inner surfaces of the member 2, rnd the bottom 5, afe'preferably made extremely smooth; and cleansed after each operation,V and in this manner the Work of smoothing or polishing the finished article is much reduced.-

"Wlien actually using the mold `for form-Y ing shapes, a suitable lining 15 of paper', cloth, or equivalent, is first laidl in against the sides of the mold to insulate the artic'ial composition from thev mold vand permit the molded shape to be readily removed.

Having thus described my invention, What I 'claim and desire to secure by Letters Patent is A'mold comprising a bott-om member and a side member, WithA means for detaohably' securing them together, said members having anges on their outer edges, which flanges project toward each other, said lianges and bottom and side members in# cludlng it mold space, said flange members having p'erfor'ations, and an adjristable par? titi'on fitting in the mold space, with.` mea-ns passing throughi-saidperforatioiis 1nd erigaging with said partition to hold the same .A

1n place. l

In testimony whereof I have hereunto Set my hand in presence of two subscribing,

Witnesses;
