WILLIAM H. ALLEN, OF MOMENGE, ILLINOIS, ASSIGNOB '10 RAYMOND C. PENFIELD, OF NEW YORK, N. Y.

BRICK-HAGKING MACHINE.

Application filed March 15, 1921.

To all whom it may concern Be it known that 1, WILLIAM H. ALLEN, a citizen of the United States, and resident of Momence, in the county of Kankakee and State of Illinois haveinvented an Improvement in Brickacking Machines, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

My present invention relates to an apparatus for use in the manufacture of brick and other clay products, and more particularly to. an apparatus for hacking green brick directly from the off-bearing belt of .a brick making machine, piling and stacking the brick in desired relation for drying, setting and burning.

I believe it to be a distinct novelty to devise a machine which will automatically receive a column of green brick or a plurality of columns of brick or other clay articles, directly from the off-bearing belt of the machine, permitting a plurality of said bricks or articles to be removed from the belt without marring, injuring or damaging the same, and unloading said plurality of bricks or articles onto a platform car, dryer car, or the like, also without injury. It is, so far as I am advised, a distinct novelty in this art to automatically hack successive rows of green brick in desired spaced relation and in alternate angular positions and this capability constitutes an important feature of my present invention. A further and most important feature consists in novel means for moving the platform car, dryer car or hacking car parallel to, laterally ofand vertical with respect to the direction of travel of the stream of bricks issuing from the brick making machine, these operations taking place intermittently in any desired order, or simultaneously as may be desirable or necessary. Further novel features of the construction and arrangement of parts constituting my invention will appear as the description of the invention progresses.

In the accompanying drawlngs, illustrating the preferred embodiment of my invention,

Specification of Letters Patent.

Patented May 2, 1922.

Serial No. 452,572.

Fig. 1 is a plan view, certain constructlonal details being omitted for the sake of clearness of illustration, and

F 1g. 2 is a central longitudinal vertical lstpction, substantially on the line 2-2 of Referring to the drawings, 10 designates a pit located beneath the off-bearing belt 11 of the brick making machine (not shown). On the floor of the pit 10 is a pair of tracks 12, 12 on which run the supporting wheels 13, 13 of the platform 14. On the lower face of the platform and at one side thereof is attached a rack 15 with which meshes a gear 16 driven from an electric motor 17,

or any other suitable source of power,

mounted on the floor of the pit 10. On the end members 18 and 19 of the platform 14 are arranged tracks 20, 20, these tracks being located at right angles tothe tracks 12, 12, above referred to. On these tracks 20, 20 run flanged wheels 21 rotatably mounted in brackets 22 secured to the lower face of a platform 23. A rack 24: secured to the lower face of the platform 23 and centrally with respect to the wheels 21, as viewed in Fig. 2, has meshing therewith a gear 25 driven from a motor 26, or other suitable source of power, secured to the platform 1 1. From the above description, it is evident that the platforms 14 and 23 may be given relative movement with respect to and at right angles with each other, while being moved as a unit along the tracks 12.

On the platform 23 and at each corner thereof, are vertically arranged guideways 27 that cooperate with sliding members 28, secured to the bottom face of each corner of a platform 29, the length of the members 28 limiting the downward movement of the said platform 29. Cast integral with the platform 23, or attached thereto in any suitable manner, are hollow members 30, of sufficient internal diameter to allow free passage therethrough of the threaded bars 31, secured to the under face of the platform 29 by pins 32. Gears 33, of equal diameter and pitch, the hubs of which are threaded to fit the bars 31, are provided, one for each bar 31, as shown in Fig. 2, and these gears 33 mesh with a gear 34 secured to a shaft 35 rotatably mounted in bearings 36 on the top face of the platform 23. On the shaft 35 1s also secured a worm wheel 37 meshing with a' Worm 38 on the driving shaft of a motor 39, mounted onthe top face of the platform 23. By properly manipulating the motor 39, the gears 33 may be rotated to move the bars 31, and therefore the platform 29, upward or downward, lateral movement of said platform being prevented by engagement of the sliding members 28 with the guideways 27.

On the upper face ofthe platform 29 and extending upwardly therefrom is a circular flange 40, having formed at its upper edge a roller race 41, while centrally located and extending upwardly from the upper face of the platform 29 is a stub shaft 42.' Rotatably mounted on the stub shaft 42 is a turn table'43, on the outer lower face of which is a roller race 44 which cooperates with the roller race 41 in the platform 29, a plurality of rollers 45 being provided between said races, the whole forming an anti-friction mounting for the turntable 43. A circular depending flange 46 on the turntable 43 has formed on its outer periphery a circular rack 47 with which meshes a gear 48 secured to a shaft 49 rotatably mounted in bearings 50 on a bracket 51 secured to the upper face of the platform 29. @n the shaft 49, between the bearings 50, is secured a worm wheel 52,-

with which meshes a worm 53 secured to the driving shaft of a motor 54, mounted on the upper face of the platform 29. 0n the upper face of the turn table 43 are spaced tracks 55, which extend beyond the limits of said turntable, as shown in Fig. 2, to allow the outer ends of said tracks to rest on and be supported on the surface 56 and engagement with tracks 57 leading to a kiln or suitporarily check the flow of bricks during the time the turntable 43 is being manipulated.

While T have shown and described the various operating motors 17, 26, 39, and 54 en tirely separated from one another, T do so only for purposes of illustration, and 1t 1s to be understood that in a commerclal installation of my invention, a single switchboard having apparatus for controlling all of the said motors would be situated at a convenient point within easy reach of the operator.

The operation of my improved invention is as follows: The hacking or transfer car 5 66 is placed on the track and blocked. ina

substantially central position thereon with respect to the turntable 43. The motor 54 is operated to rotate the turntable 43 to bring the grooves 67 in the top of the transfer car 66 parallel to the length of the conveyor frame 60, and the motor 39 is operated to move the platform 29, and therefore the top surface of the transfer car 66, into proper vertical position with respect to the delivery end of the conveyor belt 11 and frame 60. The motor 17 is now operated to move the platform 14, therefore the. entire mechanism above Idescribed, to the right, as viewed in Fig. 2, the conveyor belt is started in motion to deliver bricks 59 from the brick machine (not shown) to the outlet end of the conveyor frame 60the shut-ofi' 61 being operated to allow a clear passage for said brick-and, as the bricks are fed onto the transfer car 66, the motor 17 is operated to move the transfer car to the left at a speed equal to the travel of the bricks. When a row of bricks has been fed onto said transfer car, the shut-0E 61 is manipulated to temporarily shut-0E the flow of bricks and simultaneously the motors 17 and 26 are operated to move the entire mechanism to the right, as viewed in Fig. 2, and to move the transfer car laterally with respect to the direction of movement of the conveyor 11 a sufiicient distance to allow proper positioning of the next row of bricks on the transfer car.

The above described operations are repeated until the first layer of bricks is placed on the transfer car parallel to the grooves 67, when the motor 39 is operated to lower the transfer car 66 the height of a brick and the motor 54 is operated to rotate the turntable 43 through a right angle, when the first described operations are repeated. These operationsare repeated for each layer of bricks, until when the last layer is reached, the rails 55 are at the same level as the rails 57. The conveyor 11 is stopped,

' motor 54 operated to bring the rails 55 parallel with the rails 57, motor 26 operated to bring the rails 55 into alinement with the rails 57 and motor 17 is operated to bring the rails 55 into engagement with the rails 57, when the loaded transfer car 66 is sent to the kiln or other desired point and an empty transfer car positioned on the rails 55.

While T have shown and described the preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size, shape, and arrangement of parts constituting my invention within wide limits without departing from the spirit of the invention.

My invention is further defined in the form of claims as follows:

1. Tn a hacking device for bricks and the like, the combination of means for feeding aand images like, the combination of means for feeding a plurality of bricks in succession, a turntable, a transfer car carried thereby adjacent the delivery end of said brick feeding means, means for moving said turntable parallel to the direction of movement of the bricks in said brick feeding means, and means for intermittently .movmg said turntable laterally with respect to the direction of movement of the bricks in said brick feeding means.
