IMPROVEMENT IN BRICK-MACHINES.

"The Schedule referred-to than Lottmjetmt and making part of the lame.

. To all whom it may concern:

' new and useful Improvement in Brick-Machines; and

we do hereby declare 'the following to be a full and correct description-of the same, reference being had to the accompanying drawing, in which- Figure 1 .is a horizontal section of the die and former, on line a: a: of fig. 2';

Figure 2 is an end elevation of our improved former and die; and

Figure 3 is-a section, on line 3 y of fig. 2,-of a portron of the former, showing the arrangement of the steam-space.

,The same letter marks thesame part in the severa figures where it occurs. Our invention relates to that class of brick-machines m which clay is forced in a continuous bar-through a die, and then cut into proper lengths for bricks. Such a machine is described in the patent of Oyrus Oha'm-.

hers, jr., dated September 2, 1863.

Our improvement is in thoseportions of the machine known as the-former'and die, through which the clay passes immediately'prior to its exit from the pugging and tempering-chamber.

'It consists in recessing the outer end of the. former, and mserting in .it a die, which forms a thin lining, preferably of steel, such die being held inplace and adjusted by means of set-screws, and being removable,

at pleasure, for renewal or repair, withoutv involving the removal of any portion of the former.

It further .consists in giving such a form to the steam-chamber of the former as .to supply the greatest heat to tile angles of the die, all as hereinafter more fully set forth.

The construction of our improved die and former is clearly shown in the drawing. I

The former A is intended to be attached to the end of the pugging-chamber by means of the hinge O and bolts passing through the lugs B B B.

' It is provided with a chamber, E, through which steam is caused to pass in' the direction shown by the arrows, entering hyapipe inserted at F, and escaping through another pipe inserted at G.

The construction of this steam-chamber is such, as shown in section in fig. 3, that the steam is admitted to the corners of the die where the friction of the passing 'clay is greatest, and is kept from the middle portion of the sides of the die, where the friction is least, the object being to equalize the friction, and thus prevent the uneven strain upon the bar of clay, which would tend to weaken its structure and to roughen.

the edges of the bricks.

- An oblong shouldered recess, R, is made in the end of the former A, which receives a die,'D,.of corre-' sponding shape, forming a thin steel lining to the mouth of t-lie'former.

The inner rimof this die rests upon the shoulder s s of recess It. 0

Its outer rim is beveled, as shown, the beveled surface aifording a bearing for the inner ends of the setscrews a aa. a, hywhich the die is held in place If the die should be slightly smaller than the recess R, a

the screws 0, aa a afford the means of adjusting it accurately in relation to the opening in the former, from which the clay enters the die.

In a brick-machine of the character referred to above .the die is found to wear more rapidly than other parts of the machine. Its convenient and economical replacement-hence becomes a matter of primary con- .sideration.

Having-thus fully described our invention, What we claim, and desire to secure by Letters Patent, is-- 1. The hollow former A of a brick-machine, having WILLIAM MENDHAM. CYRUS CHAMBERS, JR. Witnesses: v
