PETER J. SCHMITZ, OF ROCK ISLAND, ILLINOIS.

MOLDERS CHAPLET.

Application filed September 1, 1923.

To aZZ whom it may concern:

Be it known that I, PETER J. SoI-IMrrz, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in a Molders Chaplet, of which the following is a specification.

My invention relates to molders chaplets, such as are employed in the making of castings, to insure a proper spacing between a core and the adjacent form, While the molten metal is being poured into the mold. Some of the devices which have been devised for this purpose have not proven to be entirely satisfactory, for the reason that they do not retain their supporting qualities while the metal is filling the form, whereby the core is permitted to get out of position, and a :lefective casting results. One reason for this lies in the fact that the chaplets are provided with supporting members of a frail character, which are burned away at the first flow of the red-hot metal, their spacing possibilities being thereby destroyed. Some of such devices are so formed that they become tightly packed together, so that considerable time is lost in separating them when it is desired to use the same.

()ne of the purposes of the present invention is to provide a simple form of chaplet possessing no exposed ends which are liable to be burned away by the hot metal before they have served their purpose.

Another object is to provide a chaplet which can be readily stamped or otherwise formed from a flat piece of metal, without any loss of material.

Another purpose of the invention is to provide a chaplet having a bridge or arch formation, the supporting or spacing mem bers of which are themselves supported in a most eilicient manner.

Another purpose thereof is to provide a device of the kind named which will not readily attach itself to another one of such devices, when they are together in quantities, as in storage.

The above-named, and other features and advantages of the invention will more fully appear from the following specification, taken in connection with the accompanying drawings, in which:

Serial No. 660,656.

Fig. 1 is a perspective view of one form of the invention.

Fig. 2 is an edge view thereof.

Fig. 3 is an edge view of a modified form of the device.

Referring first to Fig. 1 of the drawings, the reference number 1 indicates a thin fiat plate, spaced apart from which is a pair of bars 2, held. in spaced relation with the plate by means of upwardly converging braces 3. The bars with their accompanying braces can be readily struck or pressed from the plate 1, leaving openings IV hen in use the chaplet is placed in position with the plate 1 in engagement with the wall of the form opposite to the core, and the core is engaged by the bars 2. In practice, one or more of the chaplets are positioned beneath the core, and a corresponding number above the same, so that in the latter case the plate 1 would be upwards, i11- stead of the bars.

It will be seen that the bars 2, with the inclined supporting end pieces 3, provide a bridge or arch formation, which is the most efficient that can be produced.

In Fig. 3 is shown a form of the invention in which the plate 5 and bars 6 are given a curved formation, and are connected by braces 7, similar in form to the braces 3. In this shape the chaplet conforms more readily to some forms of castings, and to the cores used in making the same. Other adaptations, and changes in the form and size of the chaplets can be made, as necessity demands, without departing from the spirit of the invention.

When the chaplets are in position in a mold, the molten metal flows readily thru the spaces between the plates and bars, and around the end braces, in the same manner as with other chaplets now in use.

It will be observed that there are no projecting parts of said invention, which might be burned away by the molten metal so as to destroy the spacing qualities of the chaplet. The only exposed parts in the present device are the corners of the plates, and even if these were consumed by the first influx of the metal it would not interfere with the supporting or spacing qualities of the device.

What I claim, and desire to secure by Letters Patent, is:
