june 5, i923. BASQM M. MOORE MOLD FOR TILES OR BLOCKS OF CONCRETE Filed April 18. 1922 Patented `.lune 5, i923,
NETE@ STATS MERRILL MOORE, OF CRESTON, IOWA.
.MOLD FOR TILES OR BLOCKS OF CONCRETE.
Application led April 1,8, 1922. Serial No. 554,744.
To all whom it may concern: j Be it known that I, MERRILL Moons, a citizen of the United States, residing at Creston,
in the county of Union and State of iowa, have invented certain new and useful Improvements in Molds for Tiles or Blocks of Concrete, of which the following is a specification.
This invention relates to a novel construction of mold for use in the manufacture of concrete'and other composite tile and blocks for building and other purposes, said mold being usedk with or without a number of different shaped cores'adapted to be secured within the mold. l v
*The prime `object of the invention is to provide a simple, durable, economical and vefficient device especially devised for the purposev of enabling the desired blocks and tiles .to be readily and quickly made by uno .skilled labor.
Another object of this invention is to so construct my improved mold-that it will be automatically locked together by the weight of the concrete within the mold, when the said mold is properlylilled with the concrete or other composite material.
Another object of the invention is to provide a mold which is always assembled,`and so constructed and arranged that the block or tile can readily be removed from the mold without dismantling it,fwhich is necessary in many of the molds now in use. l
A further object of this invention is to provide an individual self locking and racking mold, so constructed that the molds may be racked one on top of another until the desired height is reached, thus making it possible to place a large number of molds in a small room, without the use of racks, where the blocks or tile can be cured with artificial heat, thereby saving in both iioor kspace and fuel. Y
The foregoing and such other objects as may appear from the ensuing description are accomplished by the novell features of construction, arrangement, location and combination of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the claims appended hereto, it being understood that slight changes in the' precise form, proportions, and minor details vof construction may be resortedto without departing from the spirit or sacrificing any of the advantages of the invention. Y
In the accompanying drawings forming a part of this specification, it will ,be seen that Figure l is a central longitudinal section of a mold embodying my invention taken in theV plane of the dotted lines 1 1, Fig. 2, showing the nioldv filled with concrete or other composite material, with a core secured therein. 'i
Figure 2 isa plan view of the same. I
Figure 3 is a side elevation showing two empty molds. in their racked or stacked posdition, one resting on the top of another, an
Figure l is a transverse sectionl taken in the plane of the dotted lines 4 4, F ig. 2.
Similar numerals. of reference arey employed to designate like partsthr'oughout the several views of the drawings.
In the embodiment of my inventionas illustrated and which shows a preferred construction, the numeral l indicates the sides of the mold, 2 the bottom thereof, and
3 the end members, which extend'laterally beyond each side of the mold, and stamped inwardly from the end members at each side near the upper end thereof and at a right angle thereto is an integral :ear 1l, which is adapted to overlap and engage each side portion thereby holding the sides in their'normal position and serving to prevent any outward distortion when the molds are fully filled with the composite molding material, said sides, bottom` and end members being formed from any suitable sheet metal, which is preferably galvanized toprevent rust from .forming upon its surface.
Each end member 3 is bent inwardly the entire width of the mold at the bottom portion thereof, to form an open folded portion v5 beneath the bottom, said folded portion terminating in 4a downwardly and outwardly inclined member G at each end of the mold, said members 6 forming the seating .or supporting portions of the mold at all'times, and'passing through the bottom 2 and the folded portions of each end member isa pluralityof bolts 7, provided with threaded ends to each of which is` fitted a securing nut 8, said nuts and bolts not being drawn v tightly through said folded portions,
since the'fold'ed portions. are left sufficiently open'to permit the weight of the mold and molded- .material within the `,mold when filled, tov cause rthefolded portions to automatically close together by the entireweight resting on the members, thereby causing the end members to-remain in the closedv vposition, such as shown in Fig. l with the,
ears 4C overlapping each side of thev mold,
Vthus securing the mold in its primer..assem-y bled position when filled. y I
kIt', 4will Vbe perceived vthat when the several `parts ofl the' mold are unitedfin'-themanner hereinbefore described itforms a-single assembled structure, and thatv when itis de- 'sired to dischargea formed tile or block from the mold, it lis simply necessary to rasp the members l6 and thenfby invertin, the mold the'ends will automatically open outwardly and' allow 'the easyl and ready re- Inoval of the tile yor'blocktherefrom.v
They top portion 'of each end member is provided with a downwardly and outwardly extended flange 9, so that when it isdesired `to rack or stack the molds ,tofany desirable height within a room it is simply necessaryv to seat the lowermost members Gon the top of n the flanges 9 in the manner shown in Fig.
3 ofthe drawings."
-It is desired to usecores of'different shapes f inlconnection 'with the mold, 'andl provide "preferably a wooden4 core' 10,- .ha-ving a Vplate or bandof spring steel l1, rigidly secured yto thej top ofeach core any suitablejmanner, ypreferably by set screwsflQ, said `plate or band being providedat each end with anv overhanging downwardly andloutwardly in- -clinedyielding portion 13 adapted torestbetween'` the outwardly vprojecting fins 14 .formedon the flanges 9of` the'end members, vand serving to rigidlyhold the'end lmeml'aers against the `sides during the operation of filling. the mold and at the same time secures ythe core in its properlposition within the mold, asclearly shown in Figs. l and 2.
ln filling the mold the core. l0 is 'placed lWithin the mold, the spring steel band ll, which is fastened to theftop of said cors-rretains the corev in place andv hooks over the ends 3 of the mold, thus serving tov hold the f vends in contact with the sides while the concrete isv being placed therein., After-fthe `molds yare `filled with the .concreteithe core is removed and the molds are stacked one upon another,y the bottom portion of each mold thus retaining the top of the mold below in its "closed position, as will. bereadilyunderstoodcy .y ,n
It will be readilyunderstood that'afterthe molds shall have been properly filled with the f desiredl molding 4material the core, isy removed byA grasping the yielding portions 13, l vat each end thereof, and lifting it from the mold, the moldsthenbeing stacked one upon another, with the bottom members of eachv mold resting on; the top of the flange 9 of the mold below thus holdingthe end mem-` bers securely'inclosed position; l v 3 n Havingthus described/my invention whatr I` claim and desire to secure by Letters 13atentisz` f '1. A mold of the character described com-l prising sidesand a bottom member,and end members each formed with an open folded portion beneath-the bottom, said folded portions terminating in an inclined downwardly' sides, and end members formed with ayielding folded portion beneath the bottom and a-downwardly and outwardlyinclined flange formed at-.the top `ofgeach endmembenand ,g

A mold of the'eharacter describedcomprising a member forming the bottom and`l` lsides thereof, and end members, each" end member being formed'withv a yielding folded .portion beneath the bottom terminating in a support for the mold and a'downwardly and a :plurality of stamped out ears formed on eachA end member adapted. to overlapV and contact with eachjside, andl bolts and nuts for .yieldingly securing the end vmembers toV said bottom.
