IMPROV'ED MACHINE IOR CLEANING BRICKS.

The Schedule referred to in these Letters Patent and making part of tha saine.

To all 'wh-om it may concern:

- Be it known that I, JAMES LYON, of Norfolk, in the county of Norfolk, and in the State of Virginia,

f have invented a new and useful Machine. for Cleanbricks, by forcing them vertically through a series of rollers with colrugations.

To enable others skilled in the art to make and use' myinvention, I will proceed to describe its construc- -tion and operation.

0n a suitable frame is mounted a series of sets of four rollersone set vertically above the otherwith v corrugations, and ofthe proper size.

Each set of rollers is arranged in such a manner as to leave a space between them, on the inner'si'de,

equal to the size of the brick to be forced vertically between them.A

The journals of these rollers, by means of movable boxes, are adjustable horizontally to or from each other, l

Immediately over the opening, between the upper set of rollers, is a stationary box, or hopper, open atthe bottom, and a little larger inwidth and depth than an ordinary building-brick, and of suitable height. f A

The front side of'` this box forms a door hinged at the bottom and falling outward on two supports to a nearly horizontal position, onwhich to place the rough brick to be fed into the machine.

Across this door, on 'the outside, and a short distance above the hinge, to give a short leverage, is mounted a pin, the ends of which pla-y loosely in the slots of two arms, which lopen and close the door alternately.

By the upward stroke of a plunger, the door of the hopper is raised, which slides a brick into the machine, by ineans of the slotted arms, which are drawn up by a cross-head fastened to the plun- 4rer.

Y as they pass between thcni, over the mode of drawing the latter between the former by turning these by machinery, is that the cuttingecorrugations ofthe rollers do not become dulled so-qnicklyby this method as by the other.

The bricks, it' of different sizes, may be cut to the saine size, and, if v desired, the corrugated rollers may be so adjusted that they will cut. corrugations in the bricks, which will be of advantage in laying them in the wall.

In the drawings- Figure 1 represents a front view, with the plunger up and the door of the hopper closed by the slotted arms.

Figure Qrepresents a vertical section through the middle of the machine, with the plunger down and pressing a brick between the rollers, with another brick on the door, which has been opened by the slottedy arms. l

D, the box, or hopper for receiving the rough brick, with the hinged door F, on which is mounted the pin G.

J, the plunger, for forcing the brick H between the corrugated rollers.

This plunger is over the centre of the opening, between the rollers, and receives a vertical motion'by a piston or crank.

Fastened to the plunger' is a cross-head, which vgives motion to the slotted arms K K, to open and close the door ofthe hopper D..

rllhe motion of the plunger is adjusted so that the lowest point it reaches, is a little over the middle of the upper set of rollers, so that thenoxt brick which is fed into the machine will stand on the one already between the rollers.

Its operation is as follows:

The rollers are adjusted to suit the size of the brick.

lhe plunger', being at the lowest point, has opened the door of the hopper, hy means ofthe slotted arms,

'attached to a cross-head of the plunger, and a brick has been placed on it.

lly thel upward stroke of the plunger, the dooris closed, and the brick fed into the machine, where it is held standing nprightly on the rollers by the hopper.

In the down-stroke, the plunger presses on the brick, threes it between, and turns, by-it, the rollers, whose cntting-corrugations will remove the mortar from it.

` At the seme time, the door of the hopper is agnin ranged as herein shown and described, and operated opened, another brick fed into the machine and forced by means of forcing the bricks between. them, as herebetween the rollers, pressing on and vforcing the iirsb in set; forth. y
