OF ALEXANDRIA, VIRGINIA, ASSIGNOR TO CHAMBERS BROTHERS COMPANY, A CORPORATION OF PENNSYLVANIA.
ROTARY BRICK-MACHINE.
Specification of Letters Patent.
Application filed November 3, 1908. Serial No. 460,863.
To all to 710m it may concern Be it known that I, JOSEPH WALKER, a citizen of the United States, residing at Alexandria, in the county of 'Alexandria and State of Virginia, have invented certain new and useful Improvements in Rotary Brick-Machines, of which the following is a specification.
My invention relates to improvements in brick machines and pertains particularly to rotary machines.
The object of my invention is to provide means for returning the plungers of a rotary brick machine to their inward position ready to be filled with clay.
Another object of my invention is to provide a yielding device of this character which will not injure the plungers should clay or other obstructions get on the inside of the same, and also provide a device of this character which can be readily attached to machines of different structures.
In the accompanying drawings: Figure 1 represents a side elevation of a rotary brick machine, showing my device applied thereto, and showing the mold wheel partly in section; and Fig. 2 is an end elevation showing the mold wheel in dotted lines.
Referring now to the drawings, 1 represents the mold wheel of a rotary brick machine and 2 the pressure wheel, all of which is well understood by those skilled in the art.
and needs no further description. The mold wheel is provided in its outer periphery with the mold openings which are of the size and shape of the brick to be molded. The openings, as shown, are considerably deeper than the thickness of the brick, so as to allow the plungers to rest therein. The plunger 41 has inwardly extending stems or arms 5, all of which are of the ordinary structure and the said arms are usually operated by an arm carried by a stationary part of the machine, whereby the plungers are forced outwardly to deliver the brick therefrom.
In machines of this character, plungers will often not return to their inward position and thus cause the formation of an imperfect brick. WVhere a positive means or connection is provided for by the arms it often happens that the clay or other obstruction gets below or on the inside of the plunger and thus causes some part of the machine to give way when a positive connection is made, as the plunger can not go all the way down. In order to obviate these diificulties, I provide the castings 6 and 7 which are arranged one on each side of the mold wheel and carried by the frame 8 of the machine. These castings 6 and 7 are precisely alike and will therefore only describe one specifically. The castings, as shown, are preferably formed of a base 9 which is provided with the two upwardly extending standards 10 and 11 between which is slidably mounted the block 12. Be tween the standards of the other casting is the block 13 which is likewise mounted between the two standards. Connecting the upper ends of the casting is a cast hollow cap 14 which may be secured thereon in any desired manner and is provided with clown- \vardly turned flanges 15 and 16 which prevent the two castings from spreading. WVithin the hollow cap is a transverse and vertically movable plate 17 and extending down through the cap at each end are setscrews 18 and 19 bearing against said plate. The lower face of the plate is provided with projections 20 and 21 around which are arranged the coil springs 22 and 23 which extend down and surround the projections 24 and 25 carried by the blocks 12 and 13, whereby the springs are held in position. Between the castings is arranged a roller 26 having journals 27 and 28 bolted to the sides by the bolts 29, the said journals mounted so as to rotate in the blocks 12 and 13. The roller on its periphery is provided with lugs or projections which enter the mold openings and by the tension of the spring forces the plungers inwardly. The projections are engaged by the edges of the openings and cause the roller to revolve and thus bring the next projection to enter the succeeding opening and force the plunger inwardly. In order to prevent the wear of the edge of the openings in the mold wheel, I make the projections of the rollers of some soft material.
In operation, it will be seen that should clay or other obstructions get below the plunger the roller will move upwardly within the castings against the tension of the springs and thus no part of the machine will be injured. By screwing-the set-screws 18 and 19 in or out the spring tension on the roller is varied.
The castings are provided with rearward Patented July 9, 1912.
Between the standards 10 and 11 are stops 32 which limit the downward movement of the blocks 12 and, therefore, prevent the roller 26 from being forced too far down against the mold wheel.
I claim 1. In a rotary brick machine, the combination of a mold wheel having mold openings in its periphery, ejecting plungers movable in said openlngs, a sprlng pressed body having an engaging projection of yielding material adapted to engage and return the plunger to the bottom of the mold and then disengage therefrom during the rotation of the mold wheel.
2. In a rotary brick machine, the combination of a mold wheel having mold openings in its periphery, ejecting plungers movable in said openings, a roller provided with projections of soft material adapted to engage and return the plungers to the bottoms of the molds during the rotation of the mold wheel.
3. In a rotary brick machine, the combination of a mold wheel having mold openings in its periphery, ejecting plungers movable in said openings, a roller having spring pressed movable journal bearings and provided with projections of yielding material adapted to engage and return the plungers to the bottoms of the molds during the rotation of the mold wheel, and means for regulating the spring pressure.
In testimony whereof I afiix my signature in presence of two witnesses.
JOSEPH WALKER.
