UNITED STATES 1,501,479 PATENT, OFFICE.
ROY P. M. DAVIS, 0F MOUNT UNION, PENNSYLVANIA.
I METHOD AND APPARATUS FOR MAKING BRICK.
Application filed October4, 1922; Serial natsaeee;
zen of the United States of America, 'residing at Mount Union, in the county of Huntingdon and State of Pennsylvania, has invented certain new and useful Improvements in Methods and Apparatus for Making Brick, of which the following is a specification. v
; My invention relates to method and apparatus for making brick. j
i The object of my invention is to produce a more perfect brick than has heretofore been possible; by prior methods-and apparatus for making brick. v I
Other and more specific objects and advantages of .my invention will be in part described and in part obvious as the specification is proceeded with.
, In the accompanying drawings forming part of this specificationz.
Figure 1 is a plan View of my invention; Figure 2 is a side View; Figure 3 is a section through the mold on the line 3-3 of Figure 1;
A Figure 4 is a section on the line 1- 1 of a Figure 1 and Figure 5 shows the various steps employedin carrying out .the invention. Referring more particularly to the drawings 1, denotes a supporting frame comprising a base 2, uprights 3 and side and end beams 1 and 5, respectively. Rotatably mounted in the upright beams 3 is a shaft 6, to which is fixed intermediate their ends a pair .of rock arms 7, preferably of angle iron construction. A pair of U-shaped brackets 8, secured to the underside of the. rock arms 7 ,at the outer endsthereof as by bolts 9, carry upwardly projecting guide posts 10, for supporting the charging or preformingmold 11. -These posts 10 pass looselythroughthe upper and lower inwardly turned apertured ends 12 and 12' of brackets 13, which braek ets are ,bolted tothe ends of the charging mold as at 14. The upper apertured ends of the brackets 13 rest: upon the upper face ofthe angle; iron arms 7 and coilsprings 15 on the posts 10, engage with their lower ends the inwardly turned lower apertured 7 ends 12 of the brackets 13, and withtheir upper ends 12 engage the under face of the angle iron arms '7.
,fThe inner ends of the angle iron arms 7,
I are counter weighted by means of a counter weight 16, mounted on a shaft 17, the end-1'; of which rest upon theinner ends of said arms 7. Connecting rods 18, fixed at opposite ends to the shafts 17, and 6, connect these shafts for simultaneous movement. Coil springs 19, connected to the base 2, of the frame 1, as at 20, pass upwardly over the shaft 6, and are connected to the rock arm 7, at 21. lVhen the charger mold is swung overtoinverted position, manually or by;
any suitable automatic means (not shown) these springs serve to accelerate the, final movement of the charger mold, and also serve to check or cushion the return movement.
. Plastic brick making material is fed by; gravity from a hopper 22, into the charging or preforming mold 11, a slightly greater charge being precipitated from the hopper than is necessary to fill the compartments 232-. The excess of material is then scraped or smoothed off from the top of the mold 11,; by means of a combined scraper and scoop, elther manually or by reclpro catifng the scraper by any suitable mechanical means. (not shown). The rock arms 7, are
then swung about the axis of the shaft 6,
charger or preforming mold will continue its movement by virtue of the centrifugal force developed. However, further movement of thefmold 11, after :the rockarms come .to rest isa vertical one, along the guide rods 10, such movement being cushionedkby the springs 15, and finally completely checked when the, lower bent ends 12. of the brackets 13 come into engagement with the rock arms 7. The preformed blocks in the compartments 23 willthen be. precipitated into corresponding compartments 27in the I reforming mold 25.. The compartments 23 are slightly narrower and shorter than. the compartments27, but are of. greater depth so that the capacity of the one equals that of the other. It will of course be understood that the compartments 23 will register with the compartments 27, and that the blocks of mud from the latter will be precipitated into th former without'coming in contact with the end, or side walls thereof, consequently no mud is chipped o-fi' andlost, and the preformed bricks will be of uniform size and quality. The blocks of mud are precipitated with such force that they will spread out and completely fill the mold compartments 27, and be suitably compressed. A pallet 28' is then applied to the top of the reforming mold, and the brick ejected by means of the mold plunger-s 28, in a manner well known in the art.
In some instances it may be desirable to subject the brick to pressure in the reforming mold, in which case, after the preforming mold has precipitated the blocks of mud into the reforming mold, a pallet 30 is clamped to the preformin'g mold, by any suitable means (not shown) and the plungers are then elevated to compress the brick, by any suitable means such as the cam lever 31 The final vertical movement of the mold 11, during the discharging step, is essential, in that it overcomes the tendency of the blocks of mud under the initial centrifugal force to leave the mold 11 at a tangent.
Having thus described my invention, what I claim is:
1. The herein described method of making brick consisting in precipitating plastic material into a mold, scraping the excess material from the top of the mold to shape the brick, and then precipitating the preformed brick into a mold of slightly greater transverse and longitudinal dimensions than 'the first mentioned mold.
2. The herein described method of making brick consisting in filling a mold to overflowing with plastic material to preform a brick, removing the excess material from the top of the mold to shape .the brick. and then forcibly.dischargingthe shaped brick into a mold of greater transverse and longitudinal dimensions than the preformed brick. 3. The herein described method of makmg brick consisting in filling a mold to overfiowmg with plastic material to preform a brick, then removing the excess material, then discharging the preformed brick with considerable speed from said moldinto a second mold of greater transverse and longitudinal dimensions than the preformed brick.
4. The herein described method of maklng brick consisting in filling a mold to overflowing with plastic material, then smoothing 0d the excess material from the top of the mold, inverting said'mold over a second, mold of greater transverse and longitudinal dimensions than said first mold, and precipitating the preformed brick into said second mold.
5. The herein describedmethod of making brick consisting in filling a mold to overflowing with plastic material, smoothing off the excess material from the top of the mold to preform the brick, precipitating the brick into a mold of greater transverse and longitudinal dimensions than the brick, and then subjecting said brick to pressure in said second mold.
6. The herein described method of making brick consisting in forming a block of mud containing the exact amount of material toform. a brick, and then precipitating said block of mud into a mold having greater transverse and longitudinal dimensions but of a cubic capacity identical with the cubic volume of said block.
7.
