THEODORE LEONARD KRUPITZER, OF SOUTH JACKSONVILLE, FLORIDA.

i BRICK-CLEANING MACHINE.

Application led'April' 18, 1925. Serial No. 24,282.

To all 'whom t may concern.' j

Be it known that I, THEoDoRn L. KRUPIT- znR, a citizen of the United States, and a resident of South Jacksonville, in the county of Duval and State of Florida', have invented certain new and useful Improvements in Brick-Cleaning Machines, of which the following is a specification.

y present invention relates generally to brick cleaning machines, and more particularly to machines for cleaning used brick in preparation for reuse, more especially paving brick, and of that type embodying an open die with cutters, brick guides adjacent Vto the die, and means engageable with the brick for forcing t-he same through the die against the action of the cutters, certain of which are adjustable and spring controlled with the object in view of clearing off surface collections such as tar and the like as nearly as possible to the surfaces of the brick itself.

The primary object ofmy present invention is the provision of a simple, comparatively ineXpensive device both as to first cost and upkeep, which will be strong and durable, as well as effective and efficient in use. Y

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure 1 is a top plan view,

Figure 2 is a side elevation,

Figure 3 is a bottom plan view of one of the cutter bars,

Figure 4 is a transverse sectional view therethrough on the line 4 4 of Figure 3,

Figure 5 is a cross section through the apparatus adjacent to the die and showing the latter in frontelevation,

Figure 6 is a sectional view taken on the line 6-6 of Figure 5, v f Y Figures 7 and 8 are detail sections taken respectively on the lines 7-7 and 8 8 of Figure 5,

Figure 9 is a cross section through the frame on the line through the plunger and plunger guides, and

Figure 10 is a detail side view of the brick engaging end of the plunger.

Referring now to these figures, and particularly to Figures 1 and 2, my invention proposes the use of an elongated rectangular frame, which may be supported upon wheeled trucks and the like as well as upon a solid foundation or bed, depending upon whether or not portability is desired, it being understood that in any event the frame is effectively and solidly held in a horizontal position in order that the bricks tobe cleaned may be dropped downwardly within upstanding guides 10, below which guides the bricks come to rest upon spaced rest bars 1l, the latter paralleling the longitudinal side bars 12 of the main frame, between the ends 13 thereof and nearer to one end than the other. The rest bars 11 are in a horizontal plane slightly below the frame side bars and the guide bars 10 terminate at their lower ends in line with the upper edges of the said side bars so that the bricks drop from the guide bars and rest freely on the rest bars for a purpose which will presently appear.

The laterally spaced rest bars 11 are disn posed immediately in the rear of the die block 14, upon a transverse beam 15 forwardly of the plunger 16, and between the latter and the die block 14.

The plunger 16 has tapered sides 17 slidably disposed within the inner V-shaped grooves or side bearings 18 bolted in opposing relation to the side bars 12 of the frame, and beyond its forward end, plunger 16 has a rigid brick engaging member 19, spaced therefrom by spacing members 20 and preferably of smaller size than that of the bricks to be engaged upon forward movement of the plunger and forced forwardly from the rest bais 11 through the opening 14' of the die block 14. i j

To the rear end of the plunger 16, the forward end of a connecting rod 21 is engaged, the rear end of this connecting rod being disposed upon a crank pin 22, connecting spaced gears 23, the latter engaged by the spaced apart gears 24 of a driven shaft 25 in the rear portion of the frame, shaft 25 and the shafts of the gears 23 having bearsings respectively indicated at 26 and 27 upon the side rails or bars 12 of the frame. The driven shaft 25 which projects laterally beyond the frame at one end, has upon its projecting end a pulley 28 by means of which it may be belt connected to any suitable source of power of either a stationary or portable nature.

The die block 14 is securely bolted to and braced in connection with the side rails of bars 12 of the frame, and has along the upper and lower edges as well as the sides of its opening 14a a series of cutter bars of which the annularly disposed bars 29 and 30 along one side and one end of the opening 14a are securely bolted to the die block by bolts 31. The cutter bars 32 and 33 along the other. side and other end of the die block opening are adjustable inwardly and outwardly With their side edges movable in guide brackets 34 securely bolted to the die block, each of these latter cutter bars 32 and 33 being securely fastened to lugs 35 projecting into vertical grooves 36 ofthe die block as best seen in Figure 8 and controlled by springs 37 in said grooves, Whose tension 'is such as to force the cutter bars inwardly with respect to the `die block opening under considerable pressure.

Each of the cutter bars has along its inner edge an angularly projecting portion 38 extending away from the die block and serving :as a support for the cutter or knife 39 secured thereto, and each 'cutter bar has Ispaced pairs of ears or clamping brackets secured to and projecting therefrom, between which are bolted, riveted or otherwise fastened as at 41, a cutter guide 42 in the nature of an angular projecting blade whose `outer free end hasA a sharpened edge 43 in the same plane With the inner flat surface of Vthe respective cleaning blade 89.

Thus the bricks fed "downwardly Within ythe guides l@ and dropping from the latter onto the rest bars l1, lare intermittently engaged by the plunger and forced by the 'lab ter through the die block, such brick coming rs't into engagement With the cutter lguides 42 so that the VAlatter, engaging the faces of the brick to bev cleaned, adjusts the severalcleaning blades 39, so that the latter will be in the planes ofthe brick faces. This operation takes place by virtue of 'the yielding qualities of adjustability of the cutter bars 32' and 33; against 'the tension of their controlling springs 37, vand it is obvious that by virtue of` the sharpened brick engaging free vends of the cutter guides 42, tar or other accumulation upon the surfaces of lthe brick to be cleaned will be cut through unt-il the free ends or sharpened edgesk of the cutter `guides actually engage the surfaces of the brick. 'This insures the 'cutting the surfaces of the brick as the latter pass between the several cutters and on through the opening 14a of the die block during continued Vforward movement of theV plunger. t

the, angula'rly outstanding portionsof the E "cutter bars, may be readily removed fo'r sharpening, although vsincey these blades are so effectively guided as they are in use by the edged cutter guides 42, the necessity for sharpening the cleaning blades is rare particularly they are formed of a "good quality of hardened steel. c l

Y My invention asa Whole is effective and eihcient in use, readily lends itself to speedy operation and thus to an output of cleaned brick in considerable quantity', and is capa# ble of entirely continuous and 'efficient action throughout long periods With little if any attention except to properly feed lthe y,

bricks thereto:
