JAMES J. JOHNSTON, OF OOLUMBIANA, OHIO, ASSIGNOR TO THE UNITED STATES IMPROVEMENT COMPANY, (LIMITED,) OF SAME PLACE.

BRICK-MOLD.

SPECIFICATION forming part of Letters Patent No. 266,832, dated October 31, 1882. Application led February 23, 188:2. Renewed October 11, 1882. (No model.)

To all 'whom it may concern Be it known that I, JAMES J. JOHNSTON, of Columbiana, in the county ot' Columbiana and State of'Ohio, have invented a certain new and useful Improvement in Brick-Molds for Mold# ing Angular Brick; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in brick-molds foi"molding angular brick of the form described and represented in my application i'or Letters Patent for an improvement in brick, which bear even date with this application; and it consistsoi a stationary mold having a bottom susceptible ot' vertical movement, and a secondary bottom having side walls, which secondary bottom is used t'or the purpose olI bearing oii'77 the molded brick, as will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearly connected to make and use it., I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure 1 is a top view ot' my improvement in brick-molds. Fig. 2 is a vertical section of the same at line y y of Fig. 1. Fig. 3 is a perspective view of the secondary bottom, having side walls. Fig. 4 is a 'perspective view ot' the same with molded brick thereon. Fig. 5 is an inverted View of the saine, indicating the manner of removing the secondary bottom from the molded brick.

Reference heilig had to the accompanying drawings, A represents the base of the mold B,-which is formed by the side boards O D and the sideboard E. (indicated by dotted lines in Fig. 1.) On the edge ot' the side walls O D E is secured a top board', F, which serves the purpose ot'a feed-table for the mold B. At the lower edge of the mold A are lugs G, on which rests the outer edge ofthe movable bottom H, to which is attached an upright, I, the lower endof which moves in a guide, J, attached to the base A, to which is also secured the fulcrum K ot' the lever L, which is pivoted in said fulcrum at M, and its end pivoted in a slot at N in said upright. The mold B is provided with a secondary bottom, O, having side Walls P. This secondary bottom, with its side walls, gives form to one side and two edges of the brick, (clearly shown in Fig. 4,) and is used l'or bearing ofi:- the brick and lay ing them on the Hoor of the yard, which bearing olfand laying could not be done with hand-molded brick of the form herein described, and shown in accompanying` drawings, without some de-l 6o vice that would be the equivalent of the secondary bottom which acts similar to a mold in the delivery ot' the brick on the lloor ot' the yard, but delivers the brick much more readily than would a mold for an angular brick of the form herein described.

'The operation of molding the brick is as follows: The tempered clay is placed by the attendant on the top board, F, the secondary v bottom O and its side walls P having been 7o sanded, similar to the sanding of the o. dinary brick-mold. The brick-molder sweeps into the mold B tempered claysufeient to till and pack the mold, and cuts oft' the surplus, which the molder sweeps back onto the top board, F. He then places his t'oot on the lever L, causing the bottom H to lilt the secondary bottom O and molded brick out ot' the mold B and delivers it to the bearing-olf boy, who lays it on the tloor ot' the yard by inverting the secondary Re bottom O and removing it sidewisc, as indicated in Fig. 5. The molder havingl removed his foot from the lever L, the bottom H will drop down in the mold B to the position shown in Fig. 2. He then places a secondary bottom, O, properly sanded, in the mold. It is then ready t'or the molding ot' another brick.

Having thus described my invention, what I claim as new, and desire to srcure by Letters Patent, is 9o A mold for molding angular brick, consisting ofthe side walls O D E, secondary bottom O, having side walls P, and a movable bottom,

H, operated through the medium ot' the lever L and upright I, having guide J, substantially as herein described, and for the purpose set forth.

JAMES J. JOHNSTON.
