FIGURE 9 is a transverse sectional view taken through a rotary impact cleaner utilizing the impact members shown in FIGURES 7 and 8.

In the embodiment of the invention illustrated in the drawings, the brick cleaning machine is generally shown in FIGURES 1, 2 and 3, as comprising a truck 10, which may be a trailer truck and which includes a generally rectangular base frame 11 mounted on wheels 12 and axles 13. The lbase frame 11 has parallel spaced upright legs 15 extending upwardly from the forward end portion thereof and upright legs 16 extending upwardly from the rear end thereof and inclined inwardly to extend at right angles to longitudinally extending support beams 17 for a vibrating screen structure 19. The support beams 17 are mounted at their forward and rear ends on the legs i5 and 16 and are inclined at the angle of inclination of a screen plate 20 for the vibrating screen 19.

The vibrating screen 19 may be of any well known form land is herein shown as being a commercial form of screen known as a Ty-Rock Screen and illustrated in Catalog 68 of the W. S. Tyler Company of Cleveland, Ohio, so need not be shown or described in detail herein. The screen is generally shown as being driven in a vibratory manner by a motor 21 on the base frame 11. An endless belt 23 drives a pulley 22 from the motor 21. Said pulley is mounted on a shaft 32 suitably mounted in side plates 3d of the vibrating screen structure. The shaft 32 in turn drives counterweighted ilywheels 24 on opposite sides of the screen and vibrates the screen through oppositely extending links 25 mounted in yieldable mountings (not shown) connected with the side plates 36 for the screen as by connectors 26. The ilywheels 24 are so counterweighted and the drive to said flywheels is such as to vibrate said screen to tend to progress material from the lower discharge to the upper receiving end of said screen. The angle of inclination of the screen is such, however, that the bricks will move downwardly along the screen retarded by the conveying action of the screen.

At the upper or receiving end of the screen 19 is a hopper 29 suitably supported on the side frame plates 3G for the screen and guiding and storing brick on the screen plate 20 extending between the side plates 30.

The side plates 3d have a discharge lip 33 mounted therebetween at the discharge end thereof, for directing oversize material passing along the screen plate 20 to discharge onto a discharge chute 35, shown as being mounted on the base frame 11 in vertically spaced relation with respect thereto on legs 36.

A discharge chute 38 for undersize refuse, such as mortar, brick chips and quarter or half bricks, is mounted between the side plates 30 and extends angularly downwardly Ifrom the screen at a relatively sharp angle, to the rear end portion of the base frame 11. Said refuse chute may discharge directly onto the ground or into a conveyor or any other collecting means.

The screen plate 2d is shown in FIGURE 4 as being a rectangular mesh screen plate having a series of square openings 37 therein beneath -the hopper 29 and separated by a at surface 39. If desired, the openings 37 on one side of the flat surface 39 may be larger than the openings 37 on the opposite side of said plate surface. The openings 37 are of sufficient size to accommodate quarter and half bricks to pass therethrough, -as well as any debris and broken portions of bricks that may be discharged into the hopper 29. Beyond the openings 37 are a series of oblong openings 40. The longest dimensions of said openings extend lengthwise of the screen plate. The openings l0 are of sufficient size to accommodate chipped or undersize brick passing over the openings 37, to pass therethrough for discharge onto the discharge chute 38.

Spaced forwardly of the oblong openings 40 toward the discharge end of the screen is a series of oblong openings 41 having their longest dimensions extending transversely of the screen plate. The openings 41 are of suicient size to accommodate a full size brick to drop therethrough onto a discharge hopper 43 spaced beneath the openings 41 between the side plates 30 and receiving and storing the standard size bricks passing through the screen `and feeding the bricks for cleaning.

In advance of the openings 41 towards the discharge end of the screen plate 20 is a series of rectangular openings 44, oblong in shape, like the openings 41, with their longest dimensions extending longitudinally of the screen plate, to accommodate any full size brick which may move over the openings 41 to pass therethrough onto the hopper 43.

The hopper 43, as shown in FIGURE 2, is mounted on the upper end portions of parallel spaced side plates 45 spaced inwardly of the side plates 30 and extending upwardly from the base frame 11, on which said side plates 45 are suitably mounted. As shown in FIGURE 2, the hopper 43 has a reduced area discharge end portion 46 for discharging the bricks onto a chute structure 47 herein shown as being a roller chute structure having a plurality of rollers 49 rotatably mounted at their ends in the side plates 45, for free rotation with respect thereto in an inclined plane, inclined downwardly from the discharge end portion 46. The roller chute structure 47 extends beneath and across the discharge end portion 46 of the hopper 43 and terminates at a rotary impact cleaner 50 at the discharge end of said roller chute structure. Beneath the roller chute structure 47 and inclined downwardly toward the opposite side of the machine from the roller chute structure 47, is a roller chute structure 51 terminating at a rotary impact cleaner 53. The roller chute structures 47 and 51 are herein shown as being inclined at the same angle, although facing in opposite directions. They may, however, be inclined at different angles with respect to each other, if desired. The bricks are inverted and the direction of travel of the bricks is changed from the roller chute structure 47 and lrotary impact cleaner 50 to pass to the roller chute structure 51, by an arcuate deector plate 55, extending between the side plates 45.

The rotary impact cleaner 50 is shown in FIGURES 2, 3, and 6 as comprising two outer disks 56 rotatably mounted in openings 54 in the side plates 4S, and an intermediate disk 57 spaced between said outer disks and connected thereto by a series of tie rods 59. As shown in FIGURE 5, the tie rods 59 have nuts 60 abutting the inner Sides of the outer disks 56 and have nuts 61 threaded on the outer ends thereof for securing the disks 56 to said tie rods.

Freely mounted on the tie rods 59 are a series of irnpact members 63. As shown in FIGURE 6, the impact members 63 are in the -form of eccentrically mounted washers, although they may be concentrically mounted, if desired, as shown in FIGURE 2. The washers 63 are loosely mounted on the tie rods 59 to accommodate free rotation of said impact members with respect to said tie rods, to enable the impact members 63 to exert a hammering action on the bricks passing along the discharge end of the roller chute structure 47.

The end plate 56 opposite the motor 21 has a stub shaft 64 extending outwardly therefrom, suitably journalled in a bearing support 65 secured to the outer side of the side plate 45 and closing the opening 54 thereof. The opposite end plate 56 has a shaft 65 extending outwardly therefrom and journalled in Ia bearing support 66 suitably secured to the outer side of the opposite side plate 45 and closing the opening 54 thereof. The shaft 65 extends outwardly of the end plate 45 to the outer end portion of the base frame 11 and has a pulley 67 on its outer end, driven from the motor 21 through an endless belt 69. The shaft 65 is suitably journalled inwardly of the pulley 67 on a bearing support 70, projecting upwardly from the base frame 11. Keyed or otherwise secured to the shaft 65, inwardly of the bearing support 70 is a pulley 71, driving a pulley 73 on the outer end of a shaft 74, for driving the lower rotary impact cleaner 53. An endless belt 75 is trained about the pulleys '71 and 73. The lower rotary impact cleaner 53 is like the upper rotary impact cleaner 50, and is rotatably journalled in the side plates 45 in the same manner as the upper impact cleaner 50, so need not herein be described further.

In FIGURES 7, 8 and 9, I have shown a modified form of impact member 76, which may be substituted for the impact members 63. The impact members 76 are shown as having a central hub portion 77, from which extend sectors 79 having serrated circumferential peripheries 30. The impact members 76 like impact members 63 may be mounted on the tie rods 59 between the plates 56 and 57 for free rotation about said tie rods to exert a hammering action on the mortar on the bricks passing over the impact cleaner.

It should here 4be understood that the impact members 63 or 76 may be separated by separators such as washers (not shown) if desired, and that they may be of various other forms than the forms specifically shown herein, the form and arrangement of impact members selected being dependent upon the cleaning operation required.

In operation of the machine, used bricks may be discharged into the hopper 29 by a chute, conveyor, or power shovel or the like and fed onto the screen plate 20 of the vibrating screen 19, vibrating in a direction tending to convey the bricks from the discharge to the receiving end thereof, and thereby retarding the travel of the bricks along the screen plate sufficiently to accommodate the bricks to orient themselves to fall through the openings 41 and 44 in the screen plate. The debris and half and undersize or fragmentary and chipped bricks not suitable for reuse will pass through the openings 37 and 40 onto the refuse chute 38, where they may be discharged onto the ground or onto a conveyor or other suitable collector. The oversize bricks will pass downwardly along the screen over the openings 41 and 44 onto the discharge chute 35, which may discharge the bricks onto the ground or onto a suitable conveyor or collector.

The bricks suitable for reuse, however, will pass through the openings 41 and 44 and drop into the hopper 43 for discharge through the discharge portion 46 thereof onto the roller chute or conveyor 47, along which the lbricks will pass by gravity over the rotary impact cleaner 50. During passage of the bricks over the rotary impact cleaner 53, they are guided by the deilector plate 57 to pass around said cleaner and accommodate the impact members 63 to pass upwardly into the planes of travel of the bricks, into engagement with the mortar on the bricks with an impact action, to clean the mortar therefrom. The deflector 55 will change the direction of travel of the bricks as they pass about the rotary impact cleaner 50 and will invert the bricks to move downwardly along the inclined rotary chute 51 to the rotary impact cleaner 53, for cleaning of the opposite faces thereof from the faces cleaned by the -rotary impact cleaner 50.

It should be understood that while I have shown one angle of inclination of the roller chutes 47 and 51, that the angle of inclination of said roller chutes may be varied for different cleaning `conditions and said roller chutes may be adjusted by changing the angular relation of the side plates 45 with respect to the base frame 11 in any manner well known to those skilled in the art, and no part of the present invention so not herein shown or described.

While I have herein shown and described one form in which my invention may be embodied, it should be understood that various modifications and variations in the invention may be attained without departing from the spirit and scope of the novel concepts of the invention as defined by the claims appended hereto.
