Be it known that I, SAMUEL E. YOUNG, a citizen ofjthe United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Molds, of Which'the, fol

lowing is a specification.

The present invention relates to improvements in molding machines andhas for an obj ect the provision of an improved machine in which bricks, blocks, or other similar articles may be molded with facings made of.

r a compound giving the same a glossy or facing composition from polished appearance or fin s'h. 7

It is another object of the present inventi'on to provide an improved mold box in which separators are used to segregate the the body of the bricks'or the like.

A further object of the present invention residesin providing a simple and inexpens1ve device for use in connectlon with mold boxes wherein the facin'gs of bricks or other articles may be molded at the same time with the body portions of the brick with a view to the production of bricks or like articles having smooth and glossy surfacesaimpartedby amore expensive material, while the main body portion of the brick is composed of a rough inexpensive material.

, The invention also contemplates the use ofglass or other vitreous linings for the mold,- which cooperate with the, material used for the facings to impart a smooth and glossy finish to=the exterior of the articles. The invention will be more fully described in connection with the. accompanying draw- I ings, wherein like partsare designated by like symbols throughout the several views,

and in which; i

the separators .used in connection with the shed illustrated in Fig. 6.

Referring now more particularly to the i drawings, 1 desi nates a base supported on cleats 2, and having hinged thereto side and end walls 3 and 4: respectively. Eyes 5 on the sides 3 are arranged to receive hooks 6 pivoted on the ends 4: whereby the sides and ends may be held in an upright position as shown in Fig. 1 to form an inclosed mold" box.

A partition 7 is arranged centrally within the mold box between the ends 4, and said partition 7 and the sides 3 are provided with slots Sand 9 respectively to slidably and removably receive series of division plates 10 and 11. These division plates are spaced suitable distances apart to give the required width of the bricks or other'articles to be molded.

The partitions 10 and 11 are arranged-to rest upon glass or. other vitreous pallets 12" and 13'which are laid on the base 1 andthese pallets are preferably madein such sizes that each pallet will extend beneath approximately five of the. mold spaces defined by Glass, porcelain, or other vitreous liners l4 and 15 are positioned against opposite sides of the par-. t1tion 7 within the various mold spaces, and

such pallets and liners act to impart a smooth-and glossy finish to the exterior surfaces of thelbricks or otheiarticles molded in the machine. i

In conjunction with the glass pallets and liners I also preferably use a composition for the facings of the bricks, which is different from the body portions of the bricks which may be made of cheaper and rougher mate-1 I rial, and in carrying out this object 1' cmploy separators 16 and'l7, which are slotted throughout as indicated at 18in order to straddle the division plates lO'and fit down Within the mold spaces between suchdivision plates. As shown in Fig. 3, these sepa: rator plates16 and 17.terminate a short distance above the glass pallets 12and' 13 in orderto allow'the facing compound to escape beneath the separators and to be spread over the upper surfaces of said pallets.

The separator plates 16 and 17 are also preferably provided with enlarged slots 19 adapted to fit over the ends 4 of the mold box, and to prevent possible lateral displace- Leas es ment of the separators it is preferable to form slots in the outer facings of the end walls 4: for the purpose of receiving theportions of the separator plates adjacent the slots 19. r In the form shown in Fig. l the two separator plates 16 and 17 are formed in one piece with a shed 21 made in inverted V-shape and having diverging walls sloping towardthe opposite separator plates whereby to direct the facing compound which is poured onto the shed 21 down into the spaces confined between the separator plates 16 and 17 and the end liners 14: and 15. There are longitudinal running slots 22 at the lower edges of the divergent walls of the shed 21 and, where the shed and separa- I such facing compound enters and partially tors are made from a single piece of sheet metal, these slots 22 are provided by stamping out and striking up flanges 23, which form continuations of the separator plates and act to 'catch the facing compound as it flows down the divergent walls of the shed 21 in order to insure the passage of the compound through the slots The shed is further furnished with claws 25 projecting downwardly from the lower longitudinal edges of the divergent walls of the shed 21, and these claws 25 are provided to engage the glass liners 14 and '15 as clearly shown in Fig. 3, thus centering the shed and maintaining the liners in upright position. Referring more particularly to Figs. 6 and 7 a modification of the invention consists in making the shed and the two division plates all in separate pieces and in accordance with this form of the in,r vention, while the separators 16 and 17 are substantially unchanged, the shed 21 differs in that there are added thereto lugs 24 provided to embrace the outside faces of the end walls 4 of the mold box so as to hold 5 the shed against longitudinal movement.

In use, the machine is set up substantially as shown in Fig. 1 and the facing compound poured over the shed 21, which deflects such compound and causes it to flow down the divergent walls and into the spaces confined between the glass liners 14 and 15 and the ;separator plates 16 and 17. As the facing compound is more expensive than the body compound it is desirable to use as little of such facing compound as 1s necessary to impart a smooth and glossy facing to the articles and the separators are so arranged asto cut off small spaces at the ends of each brick .or block in the machine, into which sets before the body compound is poured into the several mold spaces formed between the division plates outside of the separators. After such facing compound has partially set and the body compound has been poured into the mold spaces the separators 16 and 17 are removed to allow the facing and body compounds to flow together and become cemented in a solid mass. The object in allow ing the facing compound to partially. set before the division plates are removed is to avoid the heavier and rougher material composing the body compound finding its way throughthe facing compound to the exterior of the bricks or blocks.

Where the shed and separators are'made in separate pieces, these parts are more convenient and less troublesometo handle especially in the larger machine, asthe same of various materials in accordance with several different formulas. For instance, one satisfactory formula consists in uniting one part of common gray cement with two parts fine sand and ten per centum by weight of cement of hydrated lime. Another formula may consist in one part white cement, two parts fine white sand and ten percentum by weight of cement of hydrated lime.

of water-proof white cement with two parts of ground marble. Still another formula for this facing compound may consist in one part white Water-proof cement with one part marble dust and one part ground marble, passing 2030 sieve.

Of course the above are merely examples of compounds that may be used in connection with the improved molding machine above described and if desirable any mineral colors may be added to secure the desired color in the brick, tile, or other articles molded.

Still another formula conslsts in uniting one part In the use of this machine there is no burning or tamping required, but the compounds are allowed to remain in. the machine for twenty-four to forty-eight hours, depending on climatic conditions, after which the articlesare removed and allowed to set thoroughly before using, which requires from two to four weeks.

I have described and illustrated preferred and satisfactory constructions, combinations and arrangements of parts,'but it is obvious that various changes may be resorted to without departing from the spirit of my invention, provided such changes fall within the scope of the appended claims.
