BRICK-MACHINE.

Specification of Letters Patent.

Patented Dec. 1907.

' Application tiled Gctobe'r 2. 1906. Serial No. 337.118.

A further object of the invention is to provide a machine having a plurality of molding chambers or compartments'whereby large quantities of bricks may be molded or pressed into shape at each operation of the machine. A

A further object is to provide improved means for tamping the bricks and means for ejecting the latter when the mold is moved to lowered position. l With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims. i

n the accompanying drawings forming a part of this speciiication: Figure 1 is a `front elevation of a brick-making machine constructed in accordance with my invention.

Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional view taken on the line 3-3 and looking in the direction of the arrow indicated in Fig. 1. Fig. 4 is a vertical sectional view of the mold supporting frame. Fig. 5 is a vertical sectional view showing the tamping element in operative position. Fig. 6 is a similar view showing the tamping element in elevated position, and the moldcarrying frame lowered to present the bricks for removal.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The machine consists of a supporting frame comprising corner posts or standards 5 connected in any suitable manner by the

transverse beams

6 and 7. Secured to the transverse beam 6 lare inwardly extending brackets 8 provided with terminal guiding loops or eyes in which are mounted for reciprocation vertical guide rods 9 the lower ends of which are secured in any suitable manner to the mold-carrying frame 10. The moldcarrying frame 10 is mounted for vertical movement with the rods 9 and is provided with a plurality of transverse and longitudinal partitions 11 dening a series of molding chambers or compartments .12 adapted to receive the concrete, cement or other lasticmaterial forming the body of. the ricks. Secured to the upper face of the mold-carrying frame 10 is a hopper 13 the walls of which are' inclined or beveled towards the molding compartments 12 so as to assist in guiding the cement into the compartments and also to prevent the cement from spilling over the mold-carryingl frame and clogging or otherwise obstructing the machine.

'One of the longitudinal walls 13 of the hopper is removable and secured in position on the mold-carrying frame by means ofl 'suitable brackets 14.

Extending transversely across the bottom of the frame is a spider the arms 15 of which are operatively connected. with the moldcarrying frame through the medium of vertically disposed rods 16 whereby when a downward movement is imparted to the spider-the mold-carrying frame will be moved to.lowered position.

As a means for lowering or depressing the mold-carrying frame there is provided a hand-operating lever 17 pivotally mounted at 18 on the adjacent post or standard 5 and having its short end connected by a link or rod 19 to the short arm of the bell crank lever 20. The lever 20 is pivotally'mounted on a shaft 21 supported by brackets or hangers 22 depending from the transverse beam 7 v ment of the latter are aplurality of Vejecting arms 27 the free ends of which form the bottom Walls of the molding compartments 12 and serve to support the bricks in position for removal from the machine when the mold-carrying frame is moved to.lowered position, as best shown in Fig. 6 of the drawings. The ejecting arms 27 are secured to andextend vertically from a plurality of spaced transverse bars 28 fastened in any suitable manner to cross-bars 29 extending between-the corner posts or standard 5.

.As a means for automatically returning the mold-carrying frame to elevated or operative position lthere are provided suitable leaf-springs 30 the `opposite ends of which are slidably mounted in suitable clips secured to transverse bars 31 while their intermediate portions bear against suitable blocks or supporting members 32 extending laterally from the mold-carrying frame, as shown. 1t will thus be seen that when the lever 17 is released the springs 32 will expand and thus move themold to elevated or operative position.

Mounted for vertical movement on the rods 9 is a frame 33 carrying a plurality of spaced plungers or tamping elements 34 adapted to enter the molding compartments 12 and compress the cement or other plastic material within the molding chambers. The frame 33 is provided with supporting brackets 35 having laterally extending perforated arms 36 for the reception of the rods 9 whereby the frame 33 is free to move up and down on said rods. Secured to the frame 33 is a rope or cable 37 the opposite end of which is wound around a drum or pulley 38 secured to a shaft 39 journaled in suitable bearings on the top of the supporting frame, as shown. Arranged in spaced relation with the shaft 39 is `an operating shaft 40 carrying a fixed pulley 41, the latter being operatively connected through the medium of a belt 42 to an engine7 motor or other suitable source of power. Secured to the opposite end of the shaft 40 is a friction pulley 43 adapted to engage a similar pulley 44 secured to and mounted for rotation with the shaft 39. The shaft 39 is mounted for rotation in an eccentric 45 provided with a depending lever 46 to the free end of which is secured a link 47 extending transversely across the frame and pivotally connected at 48 to a hand-operated lever 49. The lever 49 is pivoted at 50 to the adjacent post or standard 5 so that by moving the lever49 laterally the eccentric 45 will throw the pulley 44 into and out of engagement with thepulley 43 and thereby raise the frame carrying the tamping elements 34.

Secured to the shaft 39 is a ratchet-wheel 51 and pivotally mounted' on the frame is a pawl 52 adapted to engage the teeth on the ratchet-wheel 51 and thereby lock the shaft 39 against rotation. Secured to one end of the pawl 52 is a cord or other flexible medium 53 which extends through suitable eyes or loops and is fastened in any suitable manner to a lever 54 pivotally mounted on the free end of the operating lever 49. It will thus be seen that by releasing the pawl 452 and throwing the pulley 44 into frictional engagement with the pulley 43 the cable 27 will be wound around the drum 38 and thereby elevate the frame carrying the tamping elements and that when the eccentric is moved to release the pulley 43 the frame 33 will be locked in elevated position by the pawl and ratchet mechanism.

The operation of the device is as follows: The cement, concrete or other plastic material is shoveled or otherwise introduced into the molding-compartments 12 after which the pawl 51 is released by depressing the lever 54 thus permitting the tamping element to enter the molding chambers and 'compress the material. The tamping element is then moved to elevated position by swinging the lever 49 laterally which causes the rope or cable 37 to be wound around the drum 38. The lever 17 is then operated to depress the m'old-carryingframe thus causing the eject- .ing arms 27 to present the bricks 56 and in which position they may be readily removed from the machine. After the bricks have been removed the lever.17 is released which causes the springs 30 to automatically return the mold-carrying frame to elevated or operative position. Inv order to release the tamping element when the molding compartments are again filled it is merely necessary 4to depress the lever 54 which releases the pawl 51 thus permitting the tamping element to drop by gravity into engagement with the molding compartments as before stated.

From the foregoing descrip tion it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof isA deemed unnecessary.

Having thus described the invention what is claimed is:

1. 1n a brick-making machine, a support.- i

ing frame, a power-shaft journaled in the frame and provided with a friction pulley, an

-means for locking the tamping element in elevated position.

2. In `a brick-making machine, a supporting frame, a vertically movable mold-carrying frame, ejecting means disposed in the path of movement ofv the mold carrying frame, a tamping element, a power-shaft journaled in the frame and provided with a AJfriction pulley, an auxiliary shaft carrying a,

similar pulley adapted to engage the pulley -on the operating shaft, an eccentric carried by the auxiliary shaft for moving the pulleys into and out of engagement With each other, a lever operatively connected With the eccentric for actuating the latter, and paWl and ratchet mechanism for locking the tamping pulley secured thereto', an eccentric mounted on the auxiliary shaft, a iexible element connecting the tamping element and auxiliary shaft, a hand-operated lever operatively connected With the eccentric for throwing the friction pulleys into and out of engagement with each other, a ratchet-wheel secured to the auxiliary shaft, a pavvl adapted to engagev the ratchet-Wheel, and a iiexible connection between the operating lever and the paWl for moving the latter to operative and inoperative position.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of tWo Witnesses. Y
