BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 239,917, dated April 12, 1881.

V Application filed February 19, 1881. (No model.)

To all whomitmay concern;

Be it. known thatI, HENRY O. BARKER,

a citizen of the United States, residing at Sedalia, "in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Brick-Machines; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying 1 drawings, and to letters or figures of reference forth.

Referring to the accompanying drawings, E E indicate an upright frame planted in a suitable support or base, D, and suitably braced thereto by the inclined braces F F. Across two of these braces is supported the shaft L of the wheel H. On one side of this wheel is a series of cogs or teeth, with which engages a pinion on the end of the shaft M, suitably journaled upon one side of the middle one of the braces F, and reaching into the hopper, with means for grinding the clay therein. The-other side of this wheel H has a guttered flange, H, with a segment removed therefrom, as from H to H The flange is beveled at H to permit the slipping on" of the chain J connected to the center of the wheel H, and passed around the flange and connectedto the rope J of the weight or block 0, having the plungers c, to let the weight with its plungers fall and compress the clay in the molds, thus forming into shape the clay for bricks. The rope J, connected to the weight 0, passes over a pulley, K, hung upon the frame E.

and lower ends with springs T T, the upper ones for acceleratingjthe force of the blow of the weight with its plungers, and the lower ones for breaking the force of the fall of the "rey ersing-bar N, whichengages with the algternating cams f f and f f? on opposite sides of the upright frame E, so as to cause it to alternately strike the slides e 6 connected to one end of the chains N N passed around awheel, S, upon separate peripheries thereof,

to which the other ends of said chains are connected. The wheel S has a shaft, R, provided with a series of cams, 1?, adapted to operate upon the bottoms b of the molds a, so as to raise and lower said bottoms to push out the molded clay. An arm, I, affixed to the shaft R, is jointed to a horizontal link, g, within a slot of which works one arm of a lever, h, with its other arm connected, by a link, k, to the feeder-block B d, (I being the feeder proper.

Obliquely arranged to each other, and one fastened at the front upper edge of the feeder, and the other at the lower rear edge of the feeder, are two knives, VV, to clean away any adhering particles of clay from the molds and the plunger-s.

An off-bearing apron can be arranged conveniently to the table A, having the molds to remove the molded clay therefrom as the same is pushed out thereon by the bottoms.

It will be noticed that upon the ascent of the block with the plungers, the bar N at one end will engage with the slide e, and carry it up until the bar is intercepted by the camf, (it-previously having been brought under the slide 6 by the cam f,) freeing it from said slide. Simultaneously the wheel S will be revolved, so as to cause the cams P to elevate the bottoms b of the molds auntil the molded clayis lifted out of said molds, and so IOO upon and cause the lever is to push the block B against, and to deliver the molded clay at one side of, the mold. Duringthe further ascent of the plunger-block O the bar N will, by 5 striking the cam f,be carried under the slide 0, which will elevate the latter until the bar is intercepted and shifted by the cam f This action of the slide 6 and bar N will reverse the motion of the wheel S and its adjuncts, 10 which will have the effect to lower the .moldbottoms and move'the feeder back under the hopper and leave the molds free to receive the plungers when the block descends.

What Iclaim, and desire to secure by Letters Patent, is-

1.. In a brick-machine, the combination, with the plunger-block O and rope J J, passing over an elevated pulley, K, of the wheel H,

having the broken -away beveled flange H on one side, and a series of cogs on the other side, and the clay-grindin g shaft M, having a pinion, substantially as and for the purpose set forth.

2. The plunger-block-operating wheel H,

having the broken-away and beveled flange on one side and a series of cogs on the other side, in combination with the clay-grinding shaft M, having a pinion, substantially as and for the purpose set forth.

3. The combination, with the plunger-block 0 having eyes, of the rods X, having the springs T or T, substantially as and for the purpose set forth.

4. The combination of the block having the reversing-barN upright frame having the cams 3 5 ff f f slides e e, chains or equivalents N" N wheel S, with its shaft R, provided with cams P, and mold-bottoms 22, substantially as and for the purpose set forth.

5. The combination, with the plunger block 0, having the reversing-bar N, upright frame E, having the cams fff f and slides e 0, connected, by chains or equivalents N N to the wheel S, with its shaft R, provided with cams P, movable mold-bottoms b, of the arm l, 5 link 9, slotted at one end, lever h, link 70, and feed-block B cl, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY O. BARKER.
