MOLD FOR BRICK OR ARTIFICIAL STONE.

SPECIFICATION forming part of Letters Patent N. 679,232, dated. July 23, 1901. Application iiled December l0, 1900. Serial No. 39,263. (No model.)

To @ZZ whom it may concern:

Be it known that I, SoLoMAN M. KIMBLE, a citizen of the United States, residing at Corunna, in the county of Shiawassee, State of Michigan, have invented certain new and useful Improvements in Molds for Brick or Artificial Stone; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the igures of reference marked thereon, which form a part of this specification.

This invention relates to a machine for making brick or artificial stone; and it consists in the construction hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide simple and efficient means for forming and pressing brick made of sand and cement or other materials in such manner as to render the brick firm and compact and allow them to be removed from the press without injury, the arrangement being such as to enable the bricks to be rapidly and cheaply made.

The above object is attained by the device illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section through the brick-forming press or mold and the base upon which it is mounted. Fig. 2 is a plan view of the mold in which the bricks are formed, showing by dotted lines the movement of the horizontally-retractable dividingplates, which are adapted to separate the mold into a series of divisions adapted to contain the bricks. Fig. 3 is a transverse section showing the position of parts when the material is confined within the mold and the dividing slides or partitions are withdrawn to separate the material into a series of independent bricks. Fig. 4 is an elevation of the bricks upon the drying-board after being molded in the press. Fig. 5 is a longitudinal section through the press, showing the material therein separated into bricks by the dividing-plates. Fig. 6 is a central vertical section through the mold or press with the hopper in position thereon. Fig. 7 is a vertical transverse section through the mold, showing the bottom removed and the clamp of the mold released. Fig. S is a perspective view of the follow -board and ends of the mold or press.

The base comprises the upright parallel sides 1 and 2, united at their lower ends by the base-piece 3. Interposed between said sides near their upper end is a blockt, which is rigidly attached to the side 1 and is thereby maintained in position. Said block forms the bottom of the mold in which the bricks are formed- The sides of the mold are formed by the upper ends 5 and 6, respectively, of the sides 1 and 2, which continue above said block. The ends of the mold are formed by the end pieces 7 of the follow-board 8, which is adapted to lie upon the block 4c between the sides of the mold and support said end pieces, so as to close the ends of the mold, as clearly shown in Figs. 1, 5, and 6. The side 2, whose upper end 6 forms one of the sides of the mold, is free from the block 4., as will be seen upon referring to Fig. 7. Passing transversely through said block are the rods 9, whose outer ends pass freely through the Y side 2 and are provided with a hooked portion 10. The hooked ends of said rods lie in eccentric ways 11, formed circumferentially in the annular bar 12, which crosses the face of the side 2 and lies contiguous thereto, being supported in position by the hooked ends of the rods 9. Projecting from the bar 12 is an operative handle or lever 13, by means of which said bar may be rotated. When said bar is turned so that the hooks 10 lie in the eccentric ways 11 thereof, the side 2 is released and allowed to spring outward, as

shown in Fig. 7. By throwing the handle downward so as to rotate said bar to cause the hooks l0 to ride out of said ways, said bar is carried forcibly against the side 2, whereby said bar is clamped against the end of the block 4 and held rigidly in position, as shown in Fig. 3.

A cross-piece 14 is mounted to slide horizontally upon the ysupporting-rods 15, which are secured in the block 4 and project laterally from the side 1, their outer ends being turned upwardly, as shown at- 1G, to arrest said cross-piece in its outward movement.

Attached to said -mcvablecross-piece is a series o'f horizontallyextending approxin'iately parallel dividing blades or patitions 17,l which pass through openings in the side 5 of the mold and extend transverselyacross the'ch'am-v ber of the mold, their rear ends entering slots 18 in the side 6, whereby said dividing-blades are held firmly in position when shoved into, place across the chamber of the mold andy serve to divide said mold-chamberinto a Se'- ries of parallel spaces 19, in which the bricksM are formed, as indicated at 20. After `forming thebricks the crosspiece 14 is drawn outwardly upon the supporting-rods `15, s'o 'as -to withdraw the dividing blades or partitions from the bricks in `the mold, 'whereby the 'bricks are separated in a manner -toenable them to be discharged therefrom `and ,placed yfordrying without contact,-asjhereinafter exrplained.

A rectangular hopper 21 'is Aadapted'to be Said 'hopper adapted to be's'crewed against the Iends 7 Yto n'raintain the hopper securely in position.

lin the operation of this device the followyboard 8, which forms the bottom-of `the mold, isfirst placed upon the base-block4 between the sides 5'a'nd 6, vso that Vthe'ends '7., carried 'bysaid board, will close the 'mold and form Ythe end pieces thereof.

The lever 13-is then thrown downward, so as to clamp the side 6 of the mold in place, vand the cross-.piece 14 -is Lmoved upto the side 5 to cause'the dividing-plates to `extend across the mold and divide itinto brick-forming spaces. The `hop'- Vper isthen placed in position a-nd the sand and cement i-n proper proportion or other ma- -terials from which the-bricks are to be'formed are placedin the Vhopper so as to fill the space in the mold between the dividing-blades 17. The materia-ls -are then tamped down into said dividing-spaces, so asto com-pact said materials-between saidpa-rtit-ions, after which Vthe hopper is removeda'ndthe materials made smooth and level with the top of the mold. A drying-board 24 is then placed -upon vthe top Yof the mold and secured by the hooks v25,

which are `hinged at 26 to the ends 7. These hooks engage the opposite ends of the drying-board in a manner to maintain it `firmly in vplace upon the top of the mold. The dil viding-plates are then withdrawn Vfrom between the bricks in the' mold by drawing ontward the cross-piece 14. The bricks are then released from pressure by throwing upward v the lever 13, thereby unclamping the side 6,

materials are placed therein. 'the size-of vthe mold artificial stone of any when the-follow-board, withthebricks thereo'n, `maybe lifted from the mold. After removing the bricks from the mold they areV turned over, so as to rest upon the dryingboard 24, as shown in Fig. 4. The followboard is then removed by disengaging the 'hooks 25, thereby leaving the bricks 2O per- Afe'ct'and intact upon the drying-board to dry. After the formed bricks have been deposited upon the drying-board the followboard is again placed in the mold and the operation repeated. In this manner brick or artificial stonemay be formed of sand and cement, which when 'dry are superior for building purposes and may be very quickly and cheaply made. After the mixture from which the bricks are formed has been tamped firmly yinto the divisions of 'the 'molds the ,pressure 'uponthe dividing-plates renders it difficult to sta-rt 'the cross-piece '14 when Adesiring to withdrawithe plates from the mold. To enable "said cross-piece to be moved easily atthe start, levers 27 are pivotedo'r hinged at 2S-to't'he mold so that their short ends extend `inwardlybetween the sideof the mold Iand the cross-piece 14, in which `position a 'movement of lthe outer endofsaid levers toyward the -ends of theA mold will force said cross-piece outwa-rdlyanddraw upon vthe dividing-blades 17, as will be readily Iunder- If desi-red,'an artificial stone the entire size ofthe -mold may befo'rmed by leaving the dividing-,platesout ofthe mold-space whenthe B'ychang'ing desired vsize ymay be made.
