To all whom it may concern:

Be it known that I, JOHN and' useful Improvements in Molds for Maltm fic ation."

My invention relates to molds for forming particularly artificial tile, out of "als. such as plaster of Paris, cement and the like.

The main objectv of my im ention is to provide a articles; which will yield a perfectly smooth like defects g l g Other objects and advantages will appear hereinaftc r and while I show herewitlrand will lescr'ibe a preferred form ofconstruclimit my invention tosnch preferred form i but that various changesandadaptatlonshas been tonne may be made tl'ie'rein without departing' from the .spirit of my invention ashereim' after ela nneda;

Referring tothe drawings. which accompany this specification and form a part thereof; Fig. 1 is a plan View of the metal blank from which my mold is formed.

Fig.- 2 is a plan-view of the mold after it Fig. 1.

Fig. 3 1s a sectional YIGW through the mold shown inFlg. r

Fig. 4 is an enlarged view in perspeet-n'e of one corner of the mold shown in Fig. 2.

Fig. 5- is a sectional view of an inverted mold and a. tile"contai'ned therein, illustrating one. method of discharging a cast from he molds.

The mold is made of thin sheetmetal, preferably of a spring character. Blanks of any suitable size and shape are cut out of the sheet metal and these are bent into the desired form. The blank shown in Fig. l is intended for a square and comparatively thin tile. Corner notches are made to provide for side walls and rim flanges,leav

ing a central square 11 to ser\'e as the bottom of the mold.- The side wings 12 thus formed ,are ,l3e1it 1p wai' d along dotted lines 13, at

right angles to the bottom; to form vertical walls 14, whieh meet at their ends, thus forming loose corners 15, which may be TV. Cowntrig a citizen of the United States,"residing at" Los- Angeles. in the county of Los Angelesand; State of. California; have invented new Tile, of which the following is a speclso as to mold for casting tile and similar.

sprung apart readily when the cast is to be discharged from the mold.

Another right angled bend is made along dotted lines 16 of side wings 14 to form horizontal rim flanges 17 and creases 18 are made near the outer edge of these rim Theseicreases are made downward form shallow grooves 19 in the 11P- per sides of the flanges. 3

i In using the molds thus formed, they are filled with any plastic material employed for making tile and lilze'objeots, and are allowed to stand until thematerial hardens r sets suilicjently to he removed. l'n removing thecast the mold is inverted flanges.

and supported on the' outer edges of the flanges. Downwardpressure exerted-on thebottomthen springs tlfi walls apart opening7- 5 the corners admitting air and allowing the cast to drop out. With small molds this may he done readily by the hands, holding" the flanges withthe fingers and pressing down with the thumbs. Vithlarger molds" a device as shown in Fig. 5 may be employed-.- g

.4 hole 20, slightly larger than the cast to lae'reinorech may be made in a table top 21; gnilde strips 22,-spaced so as to admitthe mo 19 of the mold flanges, may be fixed around theopening'i'nside the guide strips 2-2. The

mold and cast may then'be inverted and placed over the hole as shown. Downward pressure on the bottom in this position, as

is evident. willspring the walls of the mold apart and allow that! cast-to drop through thetable Y Having this 11 ing a shallow container having a flexible bottom and flexible walls formed integral therewith, said flexible walls extending upwardly at right angles from said bottoms d flanges and allow fortheir expansion, may he fixed around the open1ng..and rest- 111g strips 23 adapted to engage with grooves.

Certificate of Correction.

It is hereby certified that in Letters Patent No. 1,550,950, granted August 25, 1925, upon the application of John V. jowell, of Los Angeles, California, for an improvement in Molds for Making Tile,-errors appear requiring correction as follows: Page 1, following the title, strike out the words No Drawing. One sheet of drawings containing Figures 1 to 5, inclusive, attached hereto, should appear as part of the Letters Patent; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Ofiice.
