Revendications

Claim lst In a pressed brick-making machine, a movable shaft Q actuated by crank-shaft P, and carrying a series of pivoted lever arms, whereby an up and down motion is given both to the upper plungers B and the lower plungers C, so that they will approach each other and press the brick, and recede from each other after the brick is pressed by the continuous revolution of the geared drive wheel N, as set forth. 2nd A pressed brick-making machine, constructed substantially as herein shown and described, consisting of upper plungers, in a frame adapted to move in vertical ways by means of compound levers, the same power or motion communicated from the main geared driving wheel, which causes the upper plungers to rise and fall, causing the lower plungers to rise and approach the upper plungers, so as to compress the clay in the mould openings, and to cause the upper and lower plungers to recede from each other after the clay has been pressed in the moulds, adjusting the distance between the plungers by threaded nuts and movable collars on pressure rods for lower plungers regulating the amount of clay supplied to the moulds by raising or lowering a movable frame for lower plungers, a reciprocating feed frame adapted to carry clay from hop¬per to the mould openings, intermittently after the clay has been pressed into bricks and to shove the pressed bricks onto a discharge table, a pivoted lever actuated by a revolving arm to raise the brick when pressed to the plane of discharge table, a device for automatically sanding the top and bottom of clay before pressure, and a carrier on endless belt provided for carrying clay to hopper, substantially as described and specified. 3rd. The combination, with the crank-shaft P, driven by the main geared driving wheel, of the pivoted lever arms a and b, movable shaft Q, hinged pressure frame R and RI, hinged at Z and pivoted to upper plunger frame S, and the upper plunger B and mould opening E designed to hold clay, substantially as specified. 4th The combination, with the crank-shaft P, driven by main geared driving wheel, of pivoted arm U. movable shaft Q, movable arm V pivotally attached to movable shaft Q, and eccentric cam W pivoted on fixed eccentric cam shaft T, pressure rods X fitted into caps d, di and designed to raise and lower in ways T, the lower plunger-frame C. and movable plunger frame Cs carrying movable lower plungers C, which are adapted to move in the mould openings E which hold the clay, substantially as specified. 5th The combination, with the crank-shaft P, of the pivoted lever arms a and 5, movable shaft Q, hinged pressure-frame I1 and 111, hinged at Z, the upper plunger frame S and plungers B. ways T, the pivoted arm U, movable arm V pivotally attached to movable shaft Q, and eccentric cam W pivoted on eccentric cam-shaft T, pressure rods X fitted into caps d, di and designed to raise and lower the lower plunger-frame 8, carrying lower movable plungers C, which are adapted to move in the mould openings E, which hold clay, substantially as and for the purpose specified. 6th The combination, with the pressure-rods X, threaded at each end of the cap d, pivotally attached to eccentric cam W, the cap di, nuts f, f. movable collars g, g1, with set-screws g2 and lower plunger-frame CI adapted to move in ways, substantially as and for the purpose specified. 7th The combination, with the spindle h journalled in main frame, of the hand-wheel h, mitred gear pinions h2, h3 shaft i threaded at one end and working through a collar formed at one end of pivoted bar f, the link k, handle l adapted to move through slot m and the movable lower plunger frame Cs. substantially as specified. 8th In combination with the pivoted bar j, the free end of which is designed to move up and down, as specified, the indicator m2 fixed to the free end of said pivoted bar j and the graduated scale n placed on the main frame of the machine, substantially as described and for the purpose specified. 9th The combination with cam q, having cam-groove q. and driven by the main shaft of pivoted lever-arm r, cam groove roller q2, link r2 pivotally connected with lever arm r and bell-crank lever s pivoted on shaft m1 and pitman t pivotally attached to bell-crank lever a and reciprocating feed frame G, whereby a reciprocating and intermittent motion is given to the feed frame, which carries clay from the hopper to the mould openings, substantially as specified. 10th The combination of a reciprocating feed-frame G adapted to move on guide-rods H and having bottom board Gi designed to open and close the bot¬tom of clay hopper p, a cam driven pitman t pivotally attached to said feed-frame and giving a reciprocating and intermittent motion to said feed frame G. which carries clay from the hopper to the mold openings, substantially as specified. 11th The combination, with the compartment for sand p1, situated in front of and adjoining the clay hopper of the false bottom Q, with sliding panel 3 operated by fingers 7 on spindle 4, to which an intermittent and rocking motion is given by dog 5, engaging with depression 6 in reciprocating feed-frame G and arm 14 and spring 13, whereby said is intermittently admitted from the sand hopper or compartment to the sand box F, and brush 9 on spindle 10 journalled in the sand-box F, and wheels 11 fixed on said spindle and an 3d to roll on track 12 and cause the brush to rotate and distribute sue sand evenly through the open or grated bottom of sand-box F, substantially as described and for the purpose specified. 12th A device for sanding the top and bottom of the clay in the mould openings prior to compression into bricks, consisting of a hopper for sand situate in front of and adjoining the clay hopper with a sliding panel in the bottom adapted to be moved to one side intermittently by spring and dog engaging with the reciprocating feed frame, so as to admit sand to a sand box situate in front of and forming part of the feed-frame and containing a brush on a spindle journalled in said box and caused to rotate for the purpose of keeping the sand in motion within sand box, and to distribute it evenly through the open or grated bottom of the sand box so as to sand the top and bottom of the brick, substantially as described and for the purpose specified. 13th The combination, with discharge arm w adapted to revolve on the main shaft 0, the pivoted discharging lever a centrally pivoted, the roller n2 and roller 03, movable lower plungers C, adapted to move vertically in ways and through mould openings E. so as to bring the pressed brick up to the plane of the discharge table D, and permit the reciprocating feed frame to automatically shove the pressed bricks onto the discharge table, substantially as specified. 14th A movable lower plunger, carrying a die on which the pressed brick rests, and adapted to be moved vertically through the mould opening, so as to bring the pressed brick to the same plane as the discharge table and to become automatically reseated in its normal position by the force of gravity, after the brick has been pushed into the discharge table, substantially as specified. 15th In combination with the carrier o on an endless belt. adapted to move on rollers 01 o2 journalled on the main frame and actuated by suitable gearing, the clay hopper p and reciprocating feed-frame G, carrying bottom board G., and designed to move in an intermittent manner by cam-actuated mechanism, substantially specified.
