T 0 all whom it may concern I Be it known that I, NnLsoN TL FULLER, a citizen of the United States, residing at New Bedford, in'the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Brick-Cleaning Machines, of which the following a specifurther object 'of'the invention is to provide a rotating cutter for effecting removal of the mortar, and to provide a series of resharpened and replaced.

movable cutter blades which can be removed,

A. still further object of the invention is to be gradually moved or advanced into the effective cutting plane of the cutter to thereby remove the mortar. t i

Other and further objects will be later set forth and manifested in the course of the following description. In the drawings: p f 'Figure 1, is a front elevation of the invention: 1'

Figure 2, is an end elevation: Figure 3, is an enlarged detail view in top plan and partly broken away of the cutting wheel:

Figure 1, is a rear side elevation of the cutting wheel;

Figure 5 is an enlarged section on line 5-5 of Figure 4:, and

Figure 6, is a detail perspective 'view of one of the cutting blades.

In proceeding in accordance with the present invention, any suitable supporting frame may be employed, for example a structure embodying a horizontal base 1 having supporting legs 2 and a table or work bed 3 held by standards 4.

A shaft 5 is journaled in bearings 6 and has a loose pulley 7 and a fast pulley 8 thereon, with a belt 8' trained about the driving wheel of a suitable motor 9. A cut ter wheel 10, preferably of cast form, is mounted on the front end of the. shaft 5, and is formed with a series of radial slots 11, inclined with respect to the plane of ropose.

"tation ofthe' wheel as depicted in Figurcfil of the drawings. The'bottoms of the inner ends of the slots are inclined downwardly "and inwardly to form undercut parts in which the approximately inner V-shaped ends or toes 12 ofthe cutter blades13 are conformably engaged so as to beheld against movement outwardly of the slots. In order to rigidly secure the-blades in the slots, the outer ends thereof Iha'vef'lugs'l engaged byaring 15 hinged at 16 andihavmg its ends secured together by suitable fastening device for instance the clamping [screw 17 depictedin Figures land 3 of the drawings. The ring 15 is held fixed with relation to'the wheel'by means'of angular or L-shaped clamping arms 18fequipped'with' screws 19 that bear against the rear face of the cutter wheel. Obviously as many of these arms or dogs 18 maybe employed as may be found necessary for the stated pur- The means for feeding the bricks to the cutter embody a bearing 20 attached to the table 3 and in which a rod 21 has sliding 'movement,-the

justable "stop I is arranged on 'the ta-' holding or guiding and rod having a face plate 22 secured thereto to engage the'brick's and move fsarne into engagement" wlth the cutter." An ad-' ble adjacent to the" face plate-22.' The' outer end of the rod 21' is equipped with spaced nuts or collars 2 l-between which acurved and slotted arm operates, the

connected to a depending link 26. The

ed bythe bed or base '1. A "spring'29' is latter being pivoted at 26'to the table "3 and also connected to the treadle and to the table so as to return the treadle to normal upon depression thereof. A hood or guard 30 surrounds the cuttingwheel and is secured at itsends to the base l. 1

In operation the motoris started and rotates the cutter-clockwise or towards the stop 23, the brick being'placed with one end" i I or side engaged with the stop and a second side or end engaged with the plate 22,v whereupon the treadle is depressed by-the' foot of the operator to effect. inward movement of the face plate andthereby of the brick toward the cutter, the latter removing the mortar according to the speed at which the brick is fed thereto. In this way the mortar can be removed by a somewhat grinding or slicing action on the mortar and in this manner all faces or ends of the bricks can be freed of the mortar.

It will be further seen that the cutter operates in a direction down on the brick and also in a direction towards the stop, consequently the brick requires no further holding, the face plate 22 also contributing in proper support of the brick during the cutting action. Upon release of the treadle the spring instantly moves the face plate away from the cutter so that the brick can be easily and quickly removed or turned to present another face to the cutter. The table 3v is arranged adjacent to the front end of the shaft 5 and extends diametrically of the cutter wheel so that the action of the cutting blades will be as just described.

at i ql l fil isl -l a b k c a g. machine, cutter neludin's a hen ng redia slots the inner ends of which are undercut, bladesfitted in the slots and havingtheir inner ends shaped to engage the said-undercut end walls ofthe slots, lugs on the outer ends of the blades, a split ring-engaging over the lugs to hold the blades in the slots, and clampingarms on the ring to hold the latter to the Wheel. 4 p

2. In a brick cleaning machine, a base, a. shaftsupported thereabove, means to drive the shaft, a cutter wheel on the front end of the shaft, a table supported by and above the base and; extending diametrically across thewheel, a stirrup carried by the base and depending therefrom, a foot trea-dle pivoted to the stirrup, feeding means for the bricks arranged on the table, and means actuated by thetreadle tooperate said feedingmeans.

3. In a brick cleaningmachine, a cutter including aowheel having radial grooves in its front face and having undercut parts at the inner-endsofthe grooves,vbl ades having their n e v nds shaped to e a e: n the nde t pa s and; av ng ess n their outer ends the outer edges of which, lugs lie substantially flush with theperiphe'ry of the wheel, a ring seated on the periphery of the wheel and on said outer edges of the lugs and having an inwardly extending part engaged with the front sides of the lugs, inwardly extending parts on the ring extending over the back face of the wheel, set screws projected through the last named parts and impinged against the back of the wheel, means to rotate the wheel, and a support on which the bricks are placed and moved to engage the blades.

4L. In a brick cleaning machine, a cutter including a wheel having radial grooves in its front face and having undercut parts at the inner, ends of the grooves, blades having their inner ends shaped to engage in the undercut parts and having lugs on their outer ends, a ring seated on the periphery of the wheel and havin an lnwardly fev-v tending part engaged with the front sides of the lugs, means to secure the ring to the wheel and for causing the inwardly extending part thereof to draw the lugs against the bottomsof the groovesand for preventing movementof the blades longitudinally of the grooves, means to rotatethe wheel and a support on which the bricks are-placed and moved to engage theblades.

5. In a brick cleaning machineya wheel having radial grooves. which are undercut at their innner ends, blades fitted in. the

grooves and having shoulders at-their outer ,ends, a member engaged over the periphery of the wheel and havinga front part engaging the shoulders to hold the blades against all movement in the grooves, meansto secure the member to the wheel, means to rotate the wheel, and a support on which the bricks areplaced: and. moved to engage the blades. 7
