BRlCK-MAKING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 272,224, dated February 13, 1883.

Application filed August 5, 1882.

' To all whom it may concern:

Be it known that I, Mronanr. FITZPATRICK, of St. Louis, Missouri, have invented a new and useful Improvement in Brick-Making Mae chines, of which the following is a clear, full,

and exact description, reierenco being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective viewof a brickmaking machine with my improvements attached. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation. Fig. 4. is a longitudinal section on line was of Fig. 2. Fig. 5 is a horizontal section'on line 2 z of Fig. Fig. 6 is a horizontal section on line 00 m of Fig. 3.

' My invention relates to machines for pressing bricks from clay; and it consists of the several combinations ofdevices hereinafter explained and claimed.

To enable others skilled in the art to make and use my inventioml will proceed to de-.

erated by the drum a having its bearings bej tween two of the pillars A, and the drum a having its bearings in the frame-work A. This drum is operated by means of the belt B, connecting the shaft of the drum with the main shaft of the machine. Over the table A I place the revolving table B, secured on the vvertical shaft B which passes. through the 4.0 table A and rests in a shoe at its lower end, secured to the frame-work A. On this same shaft, and below table A is rigidly secured the metal plate B. This plate is provided on its upper surface with four vertical pins, 1). 5 Againstthe said pins operates the notched pawl b, which is connected by the shalt b to a. reciprocating arm, b operated by the cocentric O, attached to the driving-shaft 0. It is evident that the revolution of the drivingshaft and its eccentric will, through the connection named, operate the pawl'b, drawing it hinges and allows the brick to pass down,and as (NO model.)

back until the notch catches in a pin. b, and then forcing it forward, thereby causing a partial revolution of the vertical shalt B and with it the revolving table B, which is rigidly 5 secured to the upper end of the vertical shaft. Through this revolving table are formed openings or molds c, in which to press and form bricks. As the table revolves these openings are brou gh t in turn under the hopper G which is provided with slides c for the purpose of regulating the amount of material entering the molds. 7

0n the lower face of the revolving table B, and immediately under the molds, I. attach hinged bottoms m, which drop and rise as they pass the openings in the lower table, where the bricks make their exit. The obj ct of these hinged bottoms is to catch and hold the bricks while being pressed, and by remaining under the bricks until they reach the exit-opening in thelower table preventany loose clay t'rom geting between the tables. When the exit-opening is reached the movable bottom drops on its the revolving table continues to move it the bottom is again lifted up to its place, and is closed against the bottom of the mold. These bottoms may also be used for regulating the thickness of the brick by adding a plate of any desired thickness to the upper face of the hinged bottom, and which will fit snugly in the mold as the bottom is raised. The thickness of the brick may be in this way regulated at pleasure, and on the plate may be placed letters, figures, or other characters for the purpose of stamping them on the brick.

,On the rear end of frame A is secured the lever D on rock-shaft D and provided with the plunger-s cl d, which enter the molds 0 simultaneously on the opposite sides of the revolving table. Theplunger (Z enters the mold for the purpose of pressing the brick into shape, and the plunger d descends into the mold to force the brick from the mold as the hinged bottom drops. After the plunger d has entered the mold cit is forced down by thetrip-hammer D. The handle of this hammer is rigidly secured to the rock-shaft D having its hearings in the frame A. On the handle of the hammer is attached the vertical pin d which is brought intocontact with the cam E,

which is rigidly secured on the driving-shaft 0. By the revolution of the cam acting upon the pin a the hammer D is caused to rise and at the proper moment to fall upon the plunger (7, thus securing the fall of the hammer on the plunger (1, pressing the brick in the mold 0. The upper portion of the hammer D is made hollow for the reception of additional weights for the purpose of adjusting the force of the hammer. These additional or extra weights may he held in position by a bolt passing through the hollow portion of the hammer. The rock-shalt D by means of the cam E, causes the arm E to vibrate, and this vibration, by means of the connecting-rods e, alternately operates the slide a in the hopper and allows the necessary feed to the molds. One end of the rock-shaft, to which the lever Dis rigidly secured, is provided with the arm E for the purpose of operating the shaft and lifting the lever. This arm is controlled by the cocentric G, secured to the main driving-shalt 0, operating through the connecting-rod H and supplementary pivoted rod H, as shown in Fig. 3.

Through the revolving table B is formed a slot, 1, through which I introduce a scraper for the purpose of scraping and cleaning the lower table, A when necessary to remove any clay therefrom. A stop-brake may be applied to the revolving table, so as to bring the molds directly under the flanges.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a brick-molding machine, the revolving table 13, provided with openings or molds c, in combination with the table A, provided with the opening a, the plate B provided with the pin I), and notched pawl 11, all constructed to operate substantially as and for the purpose describrd. v

2. The levolvingtable B, provided with the openings or molds c, in combination with the hinged bottoms at, substantially as and for the purpose set forth.

3. The revolving table 13, provided with openings or molds c, in combination with the lever 1). provided with the plungers d 41, substantially as and for the purpose set forth.

4. The lever D, carrying the plungers d (1, in combination with the trip-hammer D, substantially as and for the purpose set forth.

5. The lever D, naming the plungers d d, in combination with the trip-hammer D and shaft (3, provided with the cam E, substantially as and for the purpose set forth.

6. The shaft O, can; inc; the eccentric Grand the rods H H, in combination with the rockshaft provided with the arm 1') and lever D, carrying; the plungers d (1, whereby the lever and plnngers are raised and lowered, substantially as hert-in described.

7. The rockshatt D carrying the arm E, iu combination with the rods 0 and slides 0, substantially as and for the purpose set forth.
