T0 all wwm 'it may concern:

'Be it known that I, ALBERT R. CHRIST- MAN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Removing Adhering Mortar from Bricks, of which the following is a specification.

My invention relates to the cleaning of mortar from bricks, cilitate and perfect the operation and to render such operation perfectly safe. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which--` Figure l is a plan or top view ofamachine for cleanin bricks inaccordance with my invention; Fig. 2 is a side elevation of the same looking in the direction of the arrow w, Fig. l; Figs. 3 and4 are side elevations, onalarger scale, illustrating the operation of a certain die and ram whereby the preliminary cleaning of a portion of the brick is effected; Fig. 5 is a top view of said preliminary cleaning die and ram; Fig. 6 is a perspective view of the brick after the the same has been effected; Fig. 7 is a longithe main cleaning die illustrating also the manner of applying the partially cleaned brick thereto; Figs. 8,` 9,

'l0 and llare diagrams illustrating in different relations to one another a certain cam and a lever for moving one of the sides of the linal cleaning die, and Fig. l2 is a perspective view on a larger scale of said lever.

In Figs. l and 2 of the drawings, l represents the main frame, 2 a sliding plunger shaft, and 5 a connecting rod whereby the reciprocati on of such plunger by means of said crank shaft is effected, all of these parts being common and' therefore requiring no further or more detailed description.

Mounted upon the main frame, at one side of the machine, are three die plates 6, 7 and 8, the die plate 8 being vertical and the die plates 6 and 7 horizontal and disposed 'one above another and with their inner edges adjacent to the face of the die faces of all of the plates t3, 7 and 8 are toothed, as shown in Figs. 3, l and 5, and the upper horizontal plate 6 its objects being to fa.

preliminary cleaning of and the vertical plate 8 but the lower horizontal erence, pivoted at one by a spring 9 so that it can yield downwardly when the pressure of the spring is overcome, the extent of upward movement of said plate 7 being determined by the full expansion of the spring 9.

Projecting from one side of the plunger 2 through a suitable guide'slot in the corresponding side of the machine frame is an arm l() which carries a ram 11, the latter, on the back strokeof the plunger, being adapted to pass between the die plates 6 and 7 and in front of the die plate 8 at the side of the machine. The die plates 6 and 7 are relatively shallow but can receive between them a few inches of one end of the brick to be cleaned, and the acting faces vof said plates are tapered sc as to be farther separated from one another at one end than `at the other, as shown in Fig. 8. An attendant grasping an uncleancd brickat one end can, therefore, without anyrisk of injury, place its opposite end between the die plates 6 and 7 and in front of the ram 1l, as shown` in Fig. 3, the front end of the brick bearing such relation to the face of the die plate 8 that, when the brick is thrust by the advancing ram 1l between the plates 6 and 7 and across the the adhering mortar will be cleaned from plate 7, is, by prefthe top and bottom faces of the 'brick for a distance of an inch or more back from the front end. as shown in Figs. 5 and 6.

The finishing die 12 is carried by a slide 13 which is suitably guided on a transverse structure 14 at one endv of the frame, reciproat intervals by any suitable mechanism operating inconjunction with the plunger 2, this movement being such that at one of its terminations the die l2 will be in line with the ram 3 of the plunger and at the other of its terminations said die will be at one side of the machine and out of the path of the plunger, shown in Fig. l.

The nishing die is composed of opposite side plates 15, a bottom'plate 1G and a top plate 17, the bottomv plate 16 being rigid Assrenor. orv ONE-nerr face of the plate 8,v

the front end of the brick and also fromcating movement being imparted to this slide are fixed in position end and acted upon llO but the top plate 17 being pivoted at the rear end and normally depressed by the action of a coiled spring 18, as shown in Fig. 7. The top plate 17 can, however, be raised, when desired, against the pressure of the spring 18, the means employed in the pres-A ent instance for this purpose being a rod 19 pivotally connected at its lower end to the die plate 17 and likewise connected at its upper end to' the forward arm of a lever 2O which is pivotally mounted upon a standard 21 projecting' upwardly from the slide 13, as shown in Fig. 7.

As the slide 13 is moved back and forth,`

the rear arm of the lever 2O is acted upon by a cam bar 22, fiXedly mounted upon the top of the cross frame 14. The rear arm of the lever 20 has a hinged section 23 (Fig. 12) normally kept in line with the rest of the arm by. a spring 24 but Capable of yielding upwardly when subjected to pressure from below.

The action of the cam bar upon the lever` 20 is as follows, reference being had to Figs. 8, 9, 10 and 11: When the slide 13 is at that limit of its movement where the die 12 is in line with the ram 3 the lever 20 occupies the relation to the cam bar 22 shown in Fig. 8, that is to say, it is beyond the end of the cam bar and its rear arm is below the under surface of the elevated end of said cam bar.

' As the die carrying slide 13 moves to the left, the lever 20 is carried beneath the cam bar 22, as shown in Fig. 9, and is acted upon thereby so as to depress the rear arm of the lever and raise the forward arm of the same,

x thereby lifting the upper die -plate 17. Said upper dic plate is retained in the elevated position until the slide 13 has almost reached the limit of its movement to the left, whereupon theaear arm of the lever 20 passes from, under the cam bar 22, as shown in *ig/F10, and, being free to rise, permits the upper die plate 17 to be depressed by the s ring 18. On the movement of the slide 13 to the right the rear arm of the lever 2() passes over the top of the cam bar 22 and its pivoted member 23 is raised by contact with the elevated end of said cam bar, as shown in Fig. 11, but when the lever passes beyond the cam bar, said pivoted memberv snaps back to its normal position so as to pass beneath the cam bar on the next move ment of the slide 13 to the left.

Immediately in front of the die 12, lwhen the latter is iii the position shown in Fig. 1, is a rail or bar 26 which is flush with or slightly above the bottom plate 16 of the die. An attendant holding a partially cleaned brick, such as shown in Fig. 6, may, theretore, rest the cleaned end of said brick on said bar so that said cleaned end will project beyond the bar and toward the die 12, this cleaned, projecting portion of the brick,

when the die 12 reaches the position shown in Fig. l, being between the forward ends of the lower and upper plates 16 and 17 of the die, as shown in Fig.

As the die on its movement to the left approaches the brick the upper die plate 17 is raised so as to be free from contact with the upper face of the-brick, but, just as the die reaches the limit of its movement, the lever 2O passes from under the infiuenceof the cam bar 22 and the upper snaps down upon the top of the brick and securely confines said brick between the upper and lower plates of the die, whereby, as

the die moves from the side of the machinel toward the centenof the same, it will carry the partially cleaned brick with it, and will. stop with lthe'brick in line with the ram 3. When the ram advances, therefore, A.it will strike the rear end of the brick and will i force the same through thedie so as to remove the mortar from the right and left hand sides of the brick and complete the removal of the mortar from the top and bottom sides of the same.

It will be noted on reference to Fig. 7

that the top and bottom plates of the die 12 project beyond the side plates 15, conse-l quently the presence of mortar' up to the end of the brick on those sides which correspond with the side plates 15 of the die will not interfere with the proper placing of the parmuy Cleaned end of the brick between the upper and lower plates of the die.

'If desired, a bar or rail 27 may be disposed above the rail 26 for contact with the cleaned top face of the brick when the cleaned lower face of the same rests on said rail 26, thus serving to support the partially cleaned brick in position to be engaged by the top and bottom plates of the die 12, even should the attendant let go of the brick before the die reaches the proper position to engage the same.

lThe machine is -intended to be operated by two attendants one of whom, located at'one side of the machine, presents the bricks to the preliminary cleaning die and, after the partial cleaning of the brick, places it in position to be handled by the other attendant, located at the opposite side of the machine, the latter attendant presenting the partially cleaned brick in position to be clamped between `the plates 16 and 17 of the finishing die 12. In neither case, however, are the hands. of the attendants brought into position to be struck by a moving part of the machine, or caught between a fixed and adhering mortar from bricks, said mode consisting in first cleaning the mortar from opposlte sides of the brick at and near one end of the same in orderto prepare said brick for insertion between the jaws of a die, then inserting said partially cleaned sides of the brick between said. jaws, and then driving the brick through said die.

In. testimony whereof, ll have Signed my name to this specification, in the presence of two subscribing Witnesses.

ALBERT R. CHRISTMAN.
