- Y BRIGK-MOLD.
SPECIFICATION forming' part of Letters Patent No. 757,726, dated April 19, 1904. v
Original application flied June 16,1903, Serial Nok 161,664
To @ZZ whom, t 70mg/ concern:
Be it known that we, THOMAS S. ORAPP and ROBERT C. FINGH, citizens of the United States,
vent the accumulation between it and the movable bottom of sand, gravel, or such like material as working past the movable bottom would obstruct and interfere with the proper operation ofthe mold. v
The object is to improve the construction in other Ways that will be fully described, and pointed out in the claims. Y,
IVe accomplish the objects of the invention bythe mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of our invention; Fig. 2, an under side view; Fig. 3, a longitudinal vertical section showingvtwo molds and the movable bottom in elevated position in one 'of them; 1, a top plan view of the device illustrated in the other figures, with the movable bottom of one of the molds removed to show the perforate bottom; Fig. 5, a section on the line 5 5 of Fig'. 3, and Fig. 6 an end View of the device shown in Fig. 1.
Like characters of reference indicate like parts throughout the several views of the drawings.
The molds in this particular machine are in pairs on the same integral base 7, which has the ears 8, by means of which a plurality of pairs are hinged together to form an endless series; but as the essential features of the mold construction of the invention are applicable to brick-machines not employing an endless series of molds we do not desire torlimit Divided-and this application led January 12, 1904. Serial No. 188,730. (No modeiil our invention to that construction of machine. The ends of the base will be recessed at 9 9 to receive tongues 10 at the bottoms of the ends 11 11 of the molds, and the side edges of the basewill have the notches 1'2 to receive the tongues 13 of the sides 14k of the molds. The sides and ends will be secured' to the base by means of the screws 15. The said sides and ends will be oblique on their inner faces, widening from bottom to top, so asto hold removable linings 16 in position in the molds wit-hout additional fastenings. Inasmuch as the principal wear on the molds will beupon their inner faces, thesel removable linings,
made, preferably, of a non-corrosivematerial or of-hardened steel and readily removable, so asto be replaced by new ones when worn,
kare important, for the reason that merchantable brick must be of uniform size and a worn mold would produce a larger brick than the standard.
17 is the dividing-wall between the two molds of` a base. It is. placed in position between the two side walls of the moldsand is secured by screws 18as shown. This dividing-wall or partition tapers downwardly and is squared up on each side. by the removable linings.
19 represents the movable or false bottoms, which are adapted to rest upon the base 7 while the clay is being pressed into the molds.
These bottoms are secured to stems 20, which pass out through suitable openings in the base 7 and are reci procated longitudinally at proper intervals to discharge the contents of the mold by suitable mechanism. (Not shown.)
The base 7 will preferably be perforated to form the gridiron pattern shown in order to allow for the free escape of clay, sand, and all foreign material that perchance might work back between the iixed and movable bottoms. The remaining metal will be tapered to knifeedges against the false bottom to afford minimum bearings for obstructions.
Having thus fully described our invention, what we claim as new, and wish to secure by Letters Patent, is-
1. A mold for brick-forming presses hav- IO Wardly-tapering linings held by said sides and ends and a false bottom movable Within said mold.
In Witness whereof We have hereunto set our hands and seals, at Indianapolis, Indiana, this 29th day of December, A. D. 1903.
