JIM.l A. GRANT AND GEORGE A. LOWRjY, OF NEW YORK, N. Y.

Application led May 15,

This invention relatesy to machines for cleaning foreign substances, as mortar or cement, from used bricks, and includes in its objects the production of a rugged and reliable construction whereby bricks `are rapidly freed from saidy foreign substances.

A further object includes the provision of means for holding and advancing `the bricks in rectilinear` direction and intoV position to be met by the quickly moving cleanino* .deviceas each brick is brought into position. The cleanedbricks continue in their path` and are finally removed in any convenient manner.

Another objectincludes theproduction of a comparatively simple, self-contained, portable machine, which is capable of dealing repeated cutting hammer blows yto the oncom- `ing bricks tothereby `free and simultaneously remove from the opposite sides ofthe bricks the mortar or other adhering matter.

This application is a continuation in part of our copending application Serial Number Other objects will appear hereinafter, and

we attain these objects by the construction. `illustrated. in the accompanying drawings, of .whichz-s l Fig. 2is anend elevation thereof. l

cleaning machine, we provide means for moving the bricks which are to be cleaned constantly forward and directly toward the cleaning device, which, in turn, is caused to be quickly and suddenly released to meet the individual oncoming bricks, andhit the adhering mortar on the sidesof each successive brick a quick, sharp blow in a direction opposite to that of the moving brick, thereby causing the momentum of the cleaning tool and that of the brick and mortar mass.

to act from opposite directions to thus more will be described more fully below.` In the `present construction of our brickl 1926. Serial No. 109,262.

effectively remove these substances. The j cleaned bricks continue in their course and are removed by a suitable conveyor, or other means. j

A form of construction which Lembodies the principles of our invention, and which accomplishes our objects, is illustrated in the accompanying drawings. In the machine herein illustrated there is provided a main supporting frame consisting of upper horizontal bars 10 and lower horizontal bars 11, i

which are united by vertical supports12, reinforced by the bars 13.

Extension bars

14, 14 and

conveyor guiderails

15, 15 are `fas,- tened to the main frame and form the support for the brick conveyor, which will` be described more fullyhereinafter. n

The brick cleaning tool consists of apair of

parallel arms

16, 16 which are mounted n onaf pivot bar or journal 17 to rock-in

journal boxes

18, 18, carried on the main frame. A heavy weight 19 is attached to the free ends of

arms

16, 16 and this weight is supplemented by

springs

20, 20. One end of each of said springs is attached, at 21, to the cleaning tool and the other end` isfastened to the upright frame 22.` Cleaner blades 23, having cutting edges 24 and made of properly tempered tool-steel, are detachably fastened to the inner sides of the

arms

16, 16 of the cleaning toolv and held by screw bolts 25. i c

As stated above,` the cleaning tool is mounted to moveon the journal 17 andv is raise-d lagainst gravity and the tension of springs 20, 2O by a cam member 26. `It will be noted that the effective surface of this f member rises vgradually and then drops ofi `abruptly to thereby Gradually lift the cleaning tool and then abruptly release it on to the oncoming brick 27, `which has now been moved' into place by the conveyor,` whichv The combined action of` weight and spring, taken With the opposing directions of travel of the cleaningtool and that of thebrick and mortar mass', gives an impact blow which shears and jars ofi' the adhering mortar 28 from the brick which is, yduring this operation, securely fastened and caused to travel through the machine.

vThe cam member 26 -iscarried on al jouriial 35 which isdriven by reduction, gears 29 and 29', respectively, on the pulley shaft whichcarries pulley 30, andV on the cam journal 35. Pulley `30 is driven from any suitable source, as a gas engine or motor M, imparting power through lywheels 31 and drive pulley 31 to belt 32. Belt 32 is controlled by belt tensioning pulley 32, by a foot lever 33, which is held in locked position by catch lever 34 to keep the tensioning pulley in raised position when the drive pulley is permitted to run idly.

As stated above, the cam for operating the cleaning tool is attached to shaft 35 and driven from the selected source of power through pulley 30. The same drive operates the brick feed conveyor' pulley 36 and the brick discharge conveyor pulley 37 through

chain drives

38 and 39, respectively. rlhe brick discharge pulley 37 carries the discharge conveyor 40, and brick feed pulley 36 and idler 45 carry the brick feed conveyor 41. The latter conveyor comprises chain links 42, carrying slats 43 and brick stops 44. This conveyor is supported over a free pulley 45 and on the conveyor guide bars 15. At the proper distance above the feed conveyor there are provided the brick holding devices 47 and 43. These devices are carried on the frame arm 49 by

ears

50, 51 and 52. Ears 50 are provided with slots to provide for the inequalities of the brick, and the holding device 47 is tensioned on to `the bricks by springs 53. This construction permits the holding device to move up and down to thus hold the bricks as they are carried forward from the chute 54. Holder 48 is pivotally supported on ears 51. The forward spring 55 in frame 56 depresses 'this holder to securely clamp the brick while it is hit by the cleaning tool which, at the proper moment, descends and strikes the mortar on the sides of the brick a severing blow while the brick continues its forward movement. A shock absorber G0 engages block 61 in case the mortar does not require the full blow to be removed.

The brick holders 47 and 4d are provided with roller feet GQ, to permit the bricks to move freely, and the machine is provided with rollers 63 for transportation.

From the description thus far given, the operation of the machine is apparent. The machine having been put into operation, bricks are taken from the chute 54 and placed sidewise on the conveyor in proper line for Ithe cleaning tool. As the conveyor advances, the holding devices 4i" and 43 cngage and hold the successive bricks. As the brick reaches the proper position the cleaning tool is'released and descends lupon the oncoming brick to strike ol'l the adhering mortar or cement. The freed mortar or cement drops into a catch conveyor 64 and the cleaned brick is carried off by a brick conveyor 65, to be delivered into a wagon or truck, if desired. It will be noted that the Vcleaning tool is raised by the rotating cam surface 4and that its up and down motion is timed with the position and advance of the bricks. By varying the speed of the machine or the ratio of the drive gears, the rate at which the bricks are cleaned is varied. At the usual rate, the present machine is capable of easily and satisfactorily cleaning 50 bricks per minute. A. hood G5 protects the drive mechanism.

Having now described our invention, what we claim as new and useful, of our own invention, and desire t-o secure by Letters Patent, is

7. In a brick cleaning machine, the combination of a frame and a conveyor extension, a brick cleaning tool supported on said frame to oscillate in a plane determined by the medial line of said conveyor` extension, a conveyor on said extension, means for causing said conveyor to travel towards the brick cleaning tool, means associated with said conveyor for holding bricks to be cleaned as they move toward the brick cleaning tool, means for rendering said brick cleaning machine effective at predetermined intervals to impart a hammer blow to extraneous matter adhering to said bricks, and'means for removing the cleaned brick.

8. In a brick cleaning machine, the combination of a frame and a conveyor extension, a brick cleaning tool supported on said frame to oscillate in a plane determined by the medial line of said conveyor extension, a conveyor on said extension, a brick holding member extending above said conveyor along said medial lines, brick holding devices on said holding member, whereby the successive bricks are gripped and held during the cleaning process.

In testimony whereof We have hereunto set our hands on this 11th day of May, A. D. 1926.
