IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 129,225, dated July 16, 1872.

To all whom it may concern:

Be it known that we, BENJAMIN S. HEATH, of La Gygne, in the county of Linn and State of Kansas, and THOMAS W. GARDNER, of Huntington, in the county of Huntington and State of Indiana, have invented a new and valuable Improvement in Brick-Machines; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a side elevation of my invention. Fig. 2 is a plan view of the same.

Our invention has relation to brick-m achines, and consists in the improvements hereinafter particularly specified and claimed.

Aof the drawing represents a truck arranged with wheels 0 for transportation purposes. 13 represents a tube or cylinder seated upon the truck A, and G is a cross-bar extending over the open top of said cylinder. The letter D represents a vertical mixingwheel arranged in said cylinder, the lower bearing of which is in the bed-piece of the truck or in the bottom of the cylinder, while the upper bearing thereof is in the cross-bar 0. At the extreme lower end of the mixing-wheel we attach to the shaft the S-shaped springs G. These springs are double, and united at their ends, as shown, and serve as means for filling the brick-molds, as hereinafter mentioned. Above the crosslar G we attach to the shaft of the mixing- Wheel the draft-lever H, and the machine is operated byattachin g the motor to the extreme outer end thereof and rotating the mixingwheel. We usually attach small friction-wheels a to this draft-lever, as shown, for the purpose of securing ease of action and preventing .vear of the points of junction between said draft-beam and the trip-lever f, hereinafter described. The letters n represent studs or bars arranged in the inner side of the cylinder to aid the upright wheel in the process of mixing the mortar. M represents a gate or cut-oi-f arranged on the outside of the cylinder so as to move up and down between anti-friction wheels 4;, as shown. The letter i represents an arm pivoted to the top of the gate m, and hinged at its upper end totthe bent trip-lever 0. The gate m has an opening, as shown at p, to allow the mortar to pass outward to the mold. S represents a coiled spring attached at its lower end to the truck-bed, While its upper end is united with the cord or chainy that passes over the wheel 2, and is connected with the trip-lever o in the manner shown. U represents a hinged door, so constructed and arranged that when drawn upward it shall serve to hold the mold firmly against and over the opening 1, and when turned downward serves as a rest and support for said mold. K represents our brick-mold constructed in the usual form; but care must be taken that its size shall correspond with the opening 1), and it must have ears or flanches, as shown, to prevent it from passing into said opening. In place of the coiled spring S we sometimes attach a weight of proper degree, which we find will answer the purpose nearly if not quite as well as the spring.

Our device is operated as follows, to wit: The clay to be molded is placed in the cylinder and the draft-lever set in motion. After the same is properly mixed the mold is placed upright against the opening p and is immediately filled by the springs Gr. vNow, as the draft-lever passes the top of trip 0 the gate m is raised upward, thereby cutting 0d the mortar from the mold, when, by the action of the spring S after the draft-lever has passed the trip, the gate is returned to its place with a sharp quick movement, thereby giving a polish to the side of the molded brick next the cylinder. The door U is then let down and the mold with its brick removed.

It will be observed that our draft-lever is so constructed that the gate m must be opened and closed twice at each revolution of the mixing-wheel. This is accomplished by extending said lever across the cylinder, as shown.

What we claim as our invention, and desire to secure by Letters Patent, is-- 1. The double S-shaped spring G upon the shaft of the mixing-wl1ee1 l), constructed and arranged substantially as and for the purpose have hereunto subscribed our names in the A specified. presence of two witnesses.

2. The combination of the spring S or its BENJAMIN S. HEATH; equivalent, levers O and H, arm '5, and gate THOS. W. GARDNER. m, when constructed and arranged as and for Witnesses: the purpose specified. D. D. KANE,

In testimony that we claim the above we G. E. UPHAM.
