Description

H. MARTIN. BRICK AND OTHER MOLDS.
aura 12m fitlitti ditto.
HENRY MARTIN, OF BROOKLYN, NEW YORK.
Letters Patent No. 113,540, dated April 11, .1871.
IMPROVEMENTIN BRICK AND OTHER MOLDS.
'1'!!! Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, Humor MARTIN, of Brooklyn, in thecounty of Kings and State of New York, have invented ElwCBYliitlll new and useful Improvement in Brick and other Molds, of which the following is a. full, clear, and exact description, reference being bad to the accompanying drawingkibrming part of. this specificatiomand in which Figure 1 represents a top viewer plan of a. mold or mold as used for making brick, and this more particularly in machines for such purpose, although the same, but preferably with a less number of molds, chambers or compartments in it may be used for making brick by hand.
The invention comprises a plunger-frame having one or more plungcrs, provided with fect'or stops, in combination with a mold-flame having one or more molding-chambers, for reverse operation of the device as a whole as regards the side or surface made uppermost in molding and discharging the work, and wheroby, in discharging the molded article. the mold islifted from it, and the plunger made to occupy a stationary position, which prevents injury to said article when soft.
Referring to the accompanying drawing- A represents the frame of a mold of a convenient size for making brick by machinery, the same being provided with a series of molding-chambers, B, and' formed with a handle, I), at either end.,
The mold-chambers B are open top and bottom,
and have arranged within them entering from below, movable mold-bottoms or plungers D. 1
These plunger-s are carried by a frame, C, disposed below the mold-frame A, and;v provided with feet or stops E, which, when the whole mold is inverted, rest at their ends 0' on the delivery-table or surface for the discharged brick, thereby relieving the plungcrs from weight or pressure on the soft brick in the molds, and
so that, by hearing down on said plungerframe O and lifting by the handles 7) on the mold -frame A, the brick is discharged by the sliding of the molds B up over it, or is started from the molds, from which it is afterward easily droppedor shaken out; hence it is not absolutely necessary. that the stroke of the mold-frame relatively to the plunger-frame should be fully equal to the depth of the molds.
-- This mode of starting or discharging the brick from the molds is preferable to expelling it by movable plun- V gers, which cannot operate with "the brick resting u the delivery surface or table, as is here the case, an whereby the brick, especially when very soft, is pre vented 'from being injured, the bricks not having tp drop when being started, but resting flat on the lei-J:
livery-table, and being in themselves stationary, while the molds more 'or are lifted from them.
The feet oistops-E of the mold-frame not only pro vent the weight of the plungers and their frame from coming on the brick when the whole mold is inverted on or over the delivery-table, but they may also act as guides to the frame or frames by arranging them, if desirable, to pass through the handles l) of the moldframe,
F is a secondary frame secured. to the under side of the mold-frame A, and serving alike to support the whole mold when sliding it, with its top uppermost, over the bed of the machine under the filling or pressing devices, and to carry the load, by the resting o the plungers I) on it, when forcing the clay' into the molds. This frame F is so arranged in relationto the mold-frame A that when the plungersq'D are at the extreme back ends of the molds-they-project beyond the mold-frame, so that when the whole mold is iuverted to discharge the brick clearance is provided for the escape of dirt passing through the molds from below.
, by Letters Patent, is-- The feet or stops E, in combination with the plunger-frame O and mold-frame A, essentially as and for the purpose specified.
