bars A and B being adapted to abut.




SPECIFICATION forming part of Letters Patent No. 341,161, dated May 4. 1886.

I Application filed Se1iteIIIlIeI'4,l885. Serial No. 176,176. (No model.)

To all whom it Hwy concern:

Be it known that I, EDWARD ORMEROD, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Mold for Making Artificial Stone, '1 .les, Sinks, Coping, and other Building-Stones in Goncrete and Terra-Gotta, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved mold for making artificial stone slabs for different purposes.

The invention consists in construction and combination of parts and details, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the mold closed. Fig. 2 is a plan view of the same open. Fig. 3 isa side view of the same. Fig. .4. is a crosssectional elevation of the same on the line 1 at, Fig. 1, the mold being filled. Fig. 5 is a like view, the cover or die being pressed down. Fig. 6 is a cross-sectional view of the same, showing the mannerof removing the slabs or other stones. I

The mold is formed of the four bars A, B, O, and D, hinged together, the free ends of the On the outer surface of the bar 1) a bar, E, is secured, which projects beyond the end of the same, and has a notch, F, in the upper edge of the projecting part. A latch, G, is pivoted on the outer surface of the bar A, and is adapted to be passed into the notch F. A bottom board, H, fitting in the frame formed of the above bars, is provided with a staple, J, to which a chain, K, can be fastened. lhe'cover or die L, which is of sufficient size to cover the entire top of the mold, has a downwardlyproiecting part, M, on its under side, which part M fits in the top of the mold or frame.

The mold can be made of wood or metal.

The operation is as follows: The mold is closed around the edges of the bottom board, H, and locked by means of the latch Ur, and then the concrete or other composition, N, is filled into the mold up to the top edge of the same, and the cover or die L is placed on the concrete, as shown in Fig. 4, and then the mold is placed under ahyd raulic press or other pressure, the cover pressed down, whereby the projection l\'[ is forced down into the upper part of the mold, and thus the concrete or other composition is compressed. The cover or die is then removed, the mold opened, and the slab 0, formed on. the board If, is drawn out of the mold by drawing out the board. A fresh bottom board is placed in the mold and the operation repeated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A mold formed of four bars hinged together, one end bar having a notched bar projecting beyond the end, and outside bar having a pivoted latch, substantially as herein shown and described.

2. The combination, with the bars A B O l), hinged together, of the bar E, secured to the bar D, and having a notch in its project ing end, the latch G, pivoted to the bar A, and of the bottom board, H, fitting in the frame formed by the bars A 1) C l), substantially as herein shown and described.

3. The combination, with the bars A B U 'l), hi1ige(i'-'together-, of the bar E, secured to the bar D, the latch G, pivoted to the bar A, the bottom board, H, fitting in the frame formed of the bars A B C l), and the cover or die L, having the dowmvardly-projeeting part M, substantially as herein shown and described.
