A CORPORATION OF NEW YORK BRICK MOLD Application filed September 26, 1930.

molds of this type in that sand and water has collected between the end partition and the end blocks, there being a slight space left between the end block and the end partition to permit expansion and contraction of the wood of the mold under the varying conditions of moisture and dryness to which these molds are subjected. At the top of each end of present molds an iron plate is attached in such a manner as to entirely cover the end blocks and the end partitions. Thus, when passing through the sanding machines, sand works into the spaces between the end partit ons and the end blocks, and when the mold is soaked, water also works into this space.

This causes considerable delay, since the molds must all be drained of water before the molds can be put in operation, as otherwise the molding sand will become moist and wet and unsuitable for use.

A further disadvantage of the present type of molds resides in the fact that there being no free removal provided for the sand and water as above mentioned, the ends of the molds become distorted, and when being dumped, the bricks in the end cavities or molds will not dump, but will be held in said cavities by the distortion of the molds.

An important object of the present invention, therefore, resides in the provision of a brick mold that will dry at the ends as readily and as easily as at the center.

Another object of my invention resides in the provision of a brick mold that will not be subject to distortion at the end partitions.

A still further object of my invention resides in the construction of a mold that will Serial No. 484,567.

automatically free itself from sand and water at the end blocks.

A further obj e'ctof the invention resides in the provision of a brick mold which will dump the bricks therefrom at the ends as well as at the center.

These features, objects and advantages,

will be readily apparent to and appreciated by those skilled in the art, enabling molds constructed according to my invention to be kept in constant operation Without the previous delays necessary for thorough drying, and resulting in the smooth dumping and delivery of bricks from the individual cavities of my novel mold.

In carrying out my present invention, I provide an iron plate on the top of each end block, but space this iron plate from the top of the adjacent end partition, which may or may not have an iron plate also thereon. I also space the end block from the end partition throughout their entire height, and also space the bottom of the end block from the adjacent mold bottom panel.

Thus a continuous and uninterrupted passage is provided from top to bottom of my.

novel mold at each end thereof. Thus when a mold constructed accordmg to my invent1on 1s passed through the sand ng machme,

no sand will collect between the end parti tion andthe end block, but will drop completely therethrough. Also, when the molds are soaked during the process of brick manufacture, the'water will pass directly through the mold at the point between the end partition and the end block. Thus, when the mold is drying, the entire mold will dry evenly, and there will be no distortion of the end partition due to the presence of water and sand. in the space between the end block and end partition. I

I believe that amold constructed as above briefly described is novel, and have therefore, claimed the same in this application.

The above and other objects and features of the invention, details of construction, combinations, and advantages, will be hereinafter more fully pointed out, described, and claimed.

Referring to the drawings, illustrating a as i preferred embodiment of the present invention,

Fig. 1 is a top plan View of a mold constructed according to my invention;

5 Fig. 2 is a bottom plan view of said mold;

the end blocks, if desired.

Iron straps 7 are a'liixed to the top of each sideby screws 8, and similar straps 9 are afiixed to the bottom panels and sides. As clearly illustrated in Fig. 8, I space the end block 2 from the partition 4;, and provide on top oft-he endblocl; 2 a metallic plate 10, secured thereto by screws 11. Beeniorcing straps 12 are also secured to the top of each partition by screws 13. 5 From aninspection oi 3, it will be notedthat the inner edge of the plate 10 the inn'eredge of the block 2, and the inner edge of'the panel 6, constitute a continuous wall, all being spaced, as illustrated at 1 1, from the endpartition 4, strap 12, and adjacent bottom panel 5.

hen being passed through the sanding; machine; sandwill collect in the individual mold cai i'tiesA, but will pass completely through the passage 14-, thus preventing any collection thereof in the space between the end block 2- and partition l. Also, when subjected to wetting or soaking, water will passdirectly through said passage 14, thus preventinp; any accumulation of surplus water'or' moisture which would otherwise delay the'drying step after each molding operationl The presence of the throughand-through passage 1 1 from top to bottom at each end of'the mold will not detract from the strength and ruggedness'ot' these molds, nor from their ability to withstand the blows, shocks and hammerings to which such moles are subjected during the process of brick manufacture.

The presence of the vents 15 in each indi vidualmold cavity will provide for the ejection'ot superfluous sand and water, and will alsofpermit easy ejection or dumping of the bricks from the individual mold cavities A.

While I have necessarily described my present invention somewhat in detail, it will be) a1)preciated that I may vary the size,

ooshape, and arrangement of parts, within reasonably wide limits without departing froin'the spirit of the invention.

My invention is further described and de fined in the form of claims as follows:
