IMPROVEMENT IN BRICK-PRESSES. I

'nescheeule referred te in the Letters Paten; and making pm of the name.

To all whom it may concern Be it known that I, J AMES RCLARK, of Morenci, in the county of Lenawee and State of Michigan, have invented a new and valuable Improvement in Brick- Presses; and I do hereby declare that the following isa full, clear, and exact description ofthe construction and operation of the same, reference being hadto the annexed drawing making a part of this specification', and to the letters and.figu1 'es-of 'reference marked thereon. l

l Figure 1 of the drawing is a representation of my brick-press in plan view, and

Figure 2 lis a longitudinal vertical section of the same. f

The nature ofmy invention consists inthe construction and arrangement of abrick-press for pressing the bricks after they have been molded and partly dried iny the yard; and

To'enable others skilled iu the art to which my in-` vention appertains to make and use the same, `Il will now proceed to describe its construction and operation.

A represents the bediof my machine, at a suitable Y point on which are two posts or standards, B B.

Between the upper ends of these posts is pivoted the hand-lever C, by means of' which the press is operated.

From the lever G, on each side,a bara, extends down to a. ltoggle-joint, b, in the center of a lever, D,

f which, at one end, is pivoted orbinged to the end of the bed A, then passing between the p'osts B B the other end of said lever is hingedor pivoted to a plunger-rod or beam This rod or beam E, which, at its other end, is provided with the plunger' G, moves horizontally between two guidelblocks, H H, placed on the bed A, said blocks biengprovided with lips or tongues on their inner sides, which project into grooves in the sides of the beam.

, Whenthe jointed lever D is pressed down on the Y bed A, the plunger G just enters the mouth of a box, I, of the size of one brick, placed on the other end ot' the bed.

In addition to its stationary back, the box I is provided with a movable back, J, which is operated by a bent rod, e, connected with a p'ost,dcxtending from the beam-E through a longitudinal slot in the bed A, as shown in Iig. 2. i

It'will thus be seen that the plunger G being moved back and forth by means of the levers C D, the movable back J moves also in the same direction, but the plunger m'oves a trille farther, or else the brick would not be pressed. lhis is accomplished by passing the rod e through the post 'cl loosely, and inserting a pin, t, through the rod e on each side aud a short distance from the post. It will-then be understood that, it' a partially-dried brick is inserted between the plunger G and the back J, and then moved into the box I, the back J will stop whilethe plunger hns yet a short distance to move, and it is just then that the brick is pressed.

Having thus fully described my invention, What I claim asnew, and desire tosecure by Letters Patent, is-

Y 1. Thegrooved beam E and plunger G, moving between the guides H H, and operating in combination with the post d, rod e, pins 'i i, movable back J and box I, substantially as and for the purposes herein set forth.

2. The combination of the bed A, posts B B,- levers C D, joint b, beam E, Aplunger G, guides H H, box I, and movable backv J, all constructed and arranged to ope-rate substantially as and for the purposes herein set forth. v

In testimony that I claim the above, -I have nere-4 unto subscribed my name in the presence ot' two witnesses. Witnesses:

JAMES 1r. CLARK.
