' OF SAME PLACE.

IMPROVEMENT IN BRICK-MACHINES.

To all whom it may concern.-

Be it known that l, JOHN WATSON, of the city of Buffalo, county of Erie, and State of New York, have invented a new and Improved Connecting Rod or Bar for Brick-Machines, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure l represents a geometrical perspective view of my improved connectin g-rod, showing a part of the side of a brick-machine. Fig. 2 is a side elevation, showing the cam by which the connecting-rod receives its motion.

The nature of my invention consists in providin g a connecting-rod for draWin g the mold of a brick-machine, the said rod having a slot of sucient length as to allow the mold to move by a reciprocating motion the distance required. The said slotted connecting-rod is iitted upon the end of the main shaft of the machine so as to work freely on the same, and which serves as a guide for that end of the connecting rod or bar opposite from the end that is attached to the mold.

It further consists in constructing a cam, in combination with the slotted rod, in such a manner that while the clay is being pressed the mold remains stationary, 0r nearly so, over the brick. The cam is so constructed as to give a backward motion to the mold while the press is being drawn together. The obj ect and advantages of this backward motion are that when a uniform reciprocative motion is employed in drawing the mold the clay is drawn forward and scraped oi', thus leaving a place in the back side of the mold that is not illed with clay, so that the brick pressed in this manner leaves an imperfect corner upon the back side of the brick.

Another great advantagein my invention is that from the peculiar motion of the cam it allows the mold to remain stationary, or nearly so, while the clay is deposited in the press and While the pistons have receded to the greatest distance from each other.

It has for a long time been the great desideratum of inventors and those engaged in manufacturing brick to obtain some means to produce the proper reciprocating motion to the mold, so that it might remain stationary and directly between the two pistons when they Specification forming part of Letters Patent No. 55,432, dated June 5, 1866.

had receded to the greatest distance from each other for thev purpose of receiving the clay, and to be in the same position at the nearest approach to each other and while the clay is receiving the action of the pistons, and also to move or change its position at the proper time, that the brick may be ejected from the machine.

It will be observed that the troubles and difficulties heretofore encountered by the uniform reciprocating motion are obviated and overcome by my invention.

To enable others skilled in the art to make and use my invention, I will proceed to dc-` scribe its construction and operation.

Letters of like naine and kind refer to like parts in each of the iigures.

B represents the side of a brick-machine to which my improved connectin grod is attached.

A is the sliding top of the mold, which has an irregular reciprocating motion from the connecting-rod O. Ihe said connecting-rod O may be made of wood, iron, or any other suitable material, and is provided with a slot, D, into which passes the end of the shaft F, which is the main driving-shaft of the machine, but is no part of this invention, therefore is not shown. The end of the said shaft serves as a guide to that end of the said connecting-rod (l.V A lug or pin may also be substituted in the side of the frame B, in place of the end of the shaft, to serve as a guide.

G is the cap of the journal-box of the main shaft F.

E is the connectingjoint of the connectingrod to the sliding mold A.

I-I is the cam-wheel, or the wheel in which the cam-groove I is made, the said wheel being rigidly secured upon the shaft F.

O is a pin or lug` rmly secured to the connecting-rod O. The said pin or lug works snugly and freely in the cam-groove I, which, as the cam revolves, gives a suitable and proper motion to the sliding mold A.

It may here be observed that the connectingrod may also be worked by teeth or cogs upon the inside of the slot in the connecting-rod meshing into corresponding cogs or teeth upon the end ofthe shaft, but which are not shown in the drawings.

It will be understood that the slot D in the connecting-rod C is of sufficient length to allow the required reciprocating` motion of the con- The combination 0f the slotted rod D with necting-rod for drawing the mold of a brickthe cam I, when used to give an irregular reinachiue either by :L cam or other equivalent; ciprocatingr mot-ion to the molds of a bricknieans. machine, for the purposes and substantially I do not claim, broadly, a slotted connecting as herein described.
