UNITED STATES WILLIAM MENDHAM, oF PHILADELPHA, PENNSYLVANIA, AssiGNoR To l PATENT OFFICE CYRUS CHAMBERVJR., OF SAME PLACE.
IMPROVEMENT IN BRICK-MAKING MACHINERY.
Specification forming part' of. Letters Patent No. 207,293, dated August 20, 1878 application filed May 13, 1878.V
To all whom it may concern:
enable others skilled in the art to which ity appertains to make and use the same, reference being had to ,the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
.Figure 1 is a longitudinal vertical section, ou line y y of Fig. 2, of the screw-case' former and sand-box of a brick-machine, showing my improvements. Fig. 2 is a section, on line :c .Tof Fig. l, of the former and sand-box. Fig. 3 is a side elevation of the swinging boltior locking thel former to the screwfcase.
The vsame part is marked by the same letter wherever it occurs in the several gures.
My improvements relate to that class. of blick-machines in which the clay is pugged in a .tempering-case, driven out iu a continuons bar through a former and die, and cut by a proper severing device into suitable lengths for bricks. They are especially adapted to such a machine as that patented September 15,1863, by Cyrus Chambers, Jr., and numbered 30,884, provided with lthe steam-jacket screwcase patented by said Chambers November 1, 1870, and 4numbered 108,880.
My improvements consist, first, in making the interior of the steam# jacket screw-ease loose and removable from the main cast-in g or shell, so that the corrugated lining, which is subjected to heavy wear, may be renewed as often as may be required without thenecessityot renewing the whole case; second, in placing on the outer end of the die, whence the bar of clayissnes, a sanding-box provided with scrapers, through which the bar passes and is sanded on its way to the severing mechnmsm.
In the drawings, A marks the outer shell of the screw-case, and B the corrugated lining, which is made in a separate casting from the shell and inserted in it', as shown, and prevented from turning iu thccase by tlte feather C projecting from the inner side of the, case into a recess, I), in the outer side of the lining.
Between the shell A and the lining I? is a steam-space, E, provided with the inlet and exhaust ports F G, through which steam may be received and discharged.
The former H, which conducts the clay to th'e die I, is also provided with a steam-space, J, and with inlet-port K and exhaust-port L'. The former is hinged to the screw-case at M, Fig. 2, and is locked on the opposite side by the swinging bolt N, provided with the nut O and slider Q, and held to the case A by a pintle, P, passing through eyes R projecting from the case. lugsS, projecting from tl1e,i`ormer,.as shown, and is clamped by the nut O.
In front of the former and die is attached the sand-box, through which the bar of clay passes at it emerges from the machine The box is supplied with sand from any suitable hopper or reservoir. Near the bottom of the box -is placed a roller, U, covered with felt, which applies the sand to thebottom of the bar.
In the front of the box is au oblong rect! angular opening, larger than the cross-section of the clay bar. Around this opening, and projecting into it so'as to touch the bar on all sides, I place elastic scrapers a yb c, formed of rubber or leather, preferably the former, suiiciently stift' to hold back ,all the sand except that which adheres to the surface of the clay.
The roller U presses the sand into the body of the clay and imparts a sanded surface to the brick closely resembling that of a handmade brick. If thought desirable, such roll` ers maybe placed on all sides of the-bar.
What I claim as my improvements, and del sire to secure by Letters Patent,is
1. The screw-case lining B, made 1n a separate casting from the shell of the case, and i linserted in it, so as to be removable for rcnewal when worn, as described.
2. The sand-box '.l, provided with the elastic Y S. BERNARD CHAMBERS.
