Specification of Letters Patent.

Patented Aug. 26, 1919.

Original application filed March v1, 1916, Serial No. 81,425. Divided and this application led October 27,

. 1916. Serial No. 127,981.

To all whom. it may conce/m Be it known that. I, llamar 1V. 11AM, a citizen of the United States, at New London, in the county State of' Ohio,

residing ot Huron and have invented certain new .and useful Improvements in and Relating to Brick-Molds, of which the follow specification. i v

rlhis invention relates to. molds f ing bricks, particularly molds ot' t 'ing is a or makhe mul tiple sectional type adapted to be automatically moved to and tion below paratus.

One object ot the invention is to from the filling posithe die of a brick making approvide an improved brick mold so constructed that its upper edges 'will at all points engage with the die when moved to whereby said die will scrape oit the ay position thcrebelow,

surplus brick material as the mold is moved forwardly.

A further object of the invention is to pro vide a brick mold members adapted to enga-ge with havingr improved end various parts and supporting members otl the brick making apparatus as the mold move tates or is otherwise apparatus.

W ith these .invention consists of conveyed through the and other objects in view, the

the parts or combi nations of parts hereinafter described and set forth in the appended claims.

This application is a division ot' plication Ser.

For the purpose of illustration, I

the accompanying drawings shown my ap- No. 81,425 tiled Ma rch 1. 1916.

have, in and herein described one form of device embodying my invention.

In the drawlngs.

Fi ure lis a top planfview of a mold em bodymg my invention.

Fig. 2 is a side view ot' the in section on the line 2 2 ot Fig.

mold, partly 1. Fig.

view of4 the brick making apparatus showing certain parts thereof which engage with the end members ot' the mold to operate, support and guide the. latter.

ln the drawings, 14 indicates as an entirety the mold, adapted te move, gravitate or be conveyed through the brick making apparatus indicated as an entirety at 1 in Figs. 5 and (i. In Fig. 5, 7b indicates the front plate or wall of a charging chamber. 1d indicates side members to Iwhich is secured a. i'ront` plate 7. 13 indicates the die through which the material is forced by a press platen (notI shown). The lower surt'ace ot the die is spaced from and arranged parallel to the table or base 22 of the apparatus. 'lhe die 13 engages with the upper surface of the mold 14 when the latter is pushed i'orward over the mold table or base 22 to aY position below lthe die. The hase 2Q is so supported by suitable devices, indicated as an entirety at 2S, relative to the lower-edge ot' the die 13.v that a space, approximately equal to the height otl the mold, l-l. is let't between the base and die 13. In operating the apparatus 1.the molds are successively moved to a position below the die 18 t'or tilting-uml then forwardly, preferably, to bumping. dumping and receiving mechanisms. which are indicated in Fia. (i at 24. Q5 and 52. reslwetively, and sanding apparatus (not shown). Ot the mold. 14V indicates a pair of side members. 14 indicates a pair of end members, each preferably `connected in n, well known manner to adjacent' ends ot the side memlers 14. 14c indicates a plurality of parti ions connected at` their opposite ends to the side members 14, The partitions 14 are preferably of the same width or height as the side members 14. The partitions 14 are uniformly spaced from eachother and from the inner side walls ot the end members'lll, to divide the mold into a plurality of sections 14', each of which forms a brick mold.

` 141 indicates a plurality ot bottoms, one for each mold section 14', fixed to the -side members 1411 in any desired manner. The bottoms .14l are preferably spaced trom each othera distance slightly greater than the. thickness of each partitiomulfl.

This

tea

form or construction is for the purpose of edge oftheadfjoining partition. When the .p mold sections are if-being iilled, the air thoreinis Vforced out through these vents;

fion the other hand, when' the mold 14C is die dumped/.air .hasacoess vtothe under sides of the bricks to prevent a'vacuum.

The, end 'members 14:1l extend laterally .from tlieopposite ends of the molds'pand a'prei'erably .compnise solid blocks of rectangular shapein cross section. "lh'e blocks libere of a size` to provide relatively. wlde upper andfhrwerv fiat surfaces which serve as shoes on which the lmold 14: runs or slides on the various supporting, guiding and conveying parts of the apparatus 1 as it moves therethrough. Furthermore, the end blocks or members 14:1" provide relatively wide Hat side walls for yenga rement with the bumping devices. .The bloc s also provide bumper abutments capable of withstanding severe blimping strains, thus permitting the molds toibo' operated at a relatively ast'rate of speed and rapidly' bumped endwise to in-l sure quick andgpositive separation of the bricks from the walls ofthe mold sections. The blocks also permit the side members to be secured thereto by 'four tenons, which insures a strong mold structure,-

f V'The width of the blocks 1st is of special advantage as'they are thereby readilyl adapted L.for engagement with did'e'rent types or' supporting, nidingyl and conveying' devices,

which may or may not be spaced equallyapart, without themselves being required to .be `kept in perfect alinement at the time of delivery toor while being` moved from one point to'another on the conveying and supporting devices. olf the apparatus; in other words,fthe blocks are of a width to provide a sucient bearing surfaceto engage with and move on the various supporting parts of the apparatus without danger ot disalinement or dislodgment of the blocks therefrom. This form oi' construction is advantageously employed in connectien Ywith gravity conveyors, such as shown at 52, the rollers of which serve to guide as well as support the mold; also in con nection with supporting and operating parts which when correlated are not in alinement with each other, as shown in Fig. 6.

The upper surfaces of the blocks preferably disposed in the plane of the upper edges of the sidesyll-a and partitions 14:, but for. reasons about to be set forth, the blocks 14 are not as thick as the body portion of the mold 14 is high, that is, their lower surfaces are disposed in a plane slightly above the lower surfaces of the 14h are bottoms `1lb, as clearly Vshown in Figs. 2

and 23, ln practice, it is customary to soak 'the die,

asians? the molds in water in order to cause the sand to stick to the walls of the molds when passing through the sander. This water soaking operation causes the end members to swell slightly in size, thus increasing their height. Accordingly, when the end members of the mold were made ,equal in thickness tothe height of tlie side members or body portion of the mold and the latter was moved over the table to a position below the die 13, the table and die would engage with the end members, but as these members had, due to their water soaked condition, become thicker than the body of the' mold, they would prevent the die trom engaging the body portion 'of' the mold between the end members. As a result a space 4was formed between the body portion of the mold and the lower rsurface o the die; VVhen the mold was again moved forward, the scraping edge of the die did not scrape ofi'l the material disposed above the plane of the upper'surface of the=mold5 but due to the space-Between the upper edge or surface ofthen mold and the scraping edge of a thin layer oi" material was left on top of the mold, which material had to be scraped oli by a separate operation.

In my improved construction of mold,

the end blocks 14th are not as high as the body portion of the mold; accordin ly, even when water soaked and their thic ness is increased, the end' blocks freely movef be tween the base-22 and die 13 and permit engagement of the latter with the entire upper surface of the mold` between the end blocks 14h (as shown in Fig. 5); as a result, when the mold is positioned for [illn ing and lled and is again moved forward, the die will scrape olf all material above the upper surface of the mold.

'14 indicates a metallic binding strip eX:

tending along the upper edge of each side. member 14, then around the ends of the side members 14h andover the bottoms 14d. 14.-? indicates similar strips extendingalong the upper edges of the tpartitions 14. Each end of eacli strip/lf ispreferably secured to the adjacent'strip 14? by adoye tail joint as shown in Fig. 4f. "Mg indicates an upper plate mounted on the upper' surface of each block 14". The strips 14 and l/lf and 'the plates 14g are preferably made from the same thickness of material so that their upper surfaces will be disposed in the same plane. The strips 14:e and the plates 14g may, be 'secured to their respective mold parts in' any desired. manner, as for instance, by counter sunk screws. 14h indicates a strip eiitending along the lower edge of each partition. The strips 14h are preferably secured to the partitions 14e by rivets 14Ci which also secure the strips ll to the upper edges ofthe partitions.

The strips 121, 14E, 1l and' plates les erv retener devices of the class described, many nlterntions in. construction :und 'widely differing embodiments und applica-tiens of my in-- vention will suggest themselves without. departing; from the spirit and scope thereof; 'li/.ly disclosures and the description herein :rre purely illustrative and ere not intended te be in any sense liniiting. f
