OSCAR F. LNDBERG, OF BRADFORID, PENNSYLVANIA.

CHAPLET.

Application filed. May 22, 1913.

T0 all cairo/1n 'it may concern Be it known that I, OSCAR F. LINDBERG, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful improvements in Chaplets, of which the following is a specification.

rThis invention relates to chaplets, and has for its obj ectthe provision of a simple and inexpensive device which may be placed within a mold and readily adjusted to the distance or space between the core and the Iadjacent walls of the mold.

it secondary object of the invention is to provide a chaplet of such form that it may readily unite with the casting in the event that the molten metal should not be hot enough to entirely melt the chaplet'.

Other incidental objects of the invention will appear as the description of the same proceeds, and the invention resides in cer-- tain novel features which will be particuu larly pointed out in the claims following the description.

The invention is fully illustrated in the accompanying drawings, in which:

Figure l is a section of a mold showing my improved chaplet in position thereon; Fig. 2 is a perspective view of the chaplet showing the members of the same separated but in their proper relative positions; Figs. 3 and 4 are end views of the device showing different adjust-ments of the same; F ig. 5 is a plan view of the lower member; and Fig. 6 is side elevation of the chaplet.

ln carrying out my invention, I employ an upper member 1 and a lower member 2, each of which is preferably constructed of sheet metal and comprises a base plate and a standard projecting from the base plate. ln the upper member 1 the base plate 3 constitutes the top of the chaplet and the standard 4 projecting therefrom is constructed with parallel spaced arms 5 and 6 which are preferably of unequal length and extend from the plate 3 at the center thereof, the ends of the members of the standard being connected by a cross hea-d 7 which is preferably provided with lips or tongues 8 adapted to extend through small slots in the plate 3 and be bent over into depressions in the outer face of said base plate so as to hold the standard to the plate. The lower member 2 of the chaplet comprises a base plate 9 and a standard 10 extending the full Specification of Letters Patent.

length of the plate along the medial longitudinal line thereof and this standard, as shown most clearly in Figs. 2 and 5, is provided in its opposite faces with vertical grooves l1 adapted to receive the longer member G of the standard 4 of the top member. The distance between the 1nembers 5 and 6 of the standard 4 should be approximately equal to the thickness of the standard 10 so that when the members 5 and 6 are engaged over the standard 10 the parts will be firmly held together, and, inasmuch as the longer arm 6 of the standard 4 will have a prolonged bearing between the vertical walls of the groove ll engaged thereby, twisting of the upper member relative to the lower member will be prevented. By reference to Fig. 6, it will be noted that the standard l0 is not of uniform height throughout its length but has a different height at each groove 11 and it will, therefore, be readily understood that the device may be readily adjusted to support the core at the proper height within the mold by engaging the standard 4 of the upper member in one or another groove 1l of the lowei` member. The standard l0 is preferably formed with tongues or lips l2 upon its lower edge which are adapted to extend through small slots in the base plate 9 and be bent over into depressions in the outer face of the said plate so as to hold the standard in proper position relative to the base plate.

lt is thought the advantages of my improved device will be readily appreciated from the foregoing description, taken in connection with the accompanying drawings.

Heretofore it has been necessary to pro vide a great variety of chaplets of different heights so that one or another chaplet might be used according to the requirements of any particular mold. By the use of my device a single chaplet is adapted for use in a large variety of molds so that time heretofore lost in determining just which chaplet should be used will be now saved. A firm support for the core is provided by my chaplet and the two members may be easily and quickly itted together so that the mold may be rapidly prepared for the casting. Should the molten metal, after it is poured, cool too rapidly to entirely melt the chaplet, it will enter the grooves 11 and thereby form a good strong tie7 so that weakness in the casting will be overcome. The device is obviously simple and inexpensive and in praetioe will be found highly eioient. t

The terms upper and lower enrl ployed herein are employed for conveniencei of reference and are not to be Construedras limitations.

What I Claim is l. A ohaplet comprising a lower Ymember having a standard provided with grooves of unequal lengths, land 'an upper mem-berl havingV a standard adapted toengage-in one of: said grooves.

2. A chaplet comprising a lower plate,a standard rising therefrom and providedf with vertical grooves inits opposite'faees,` the variousheights ofthe standardin the?y planes of the respectivel grooves being -un equal, and an upper platelhaving-'means for engaging Yone of-said grooves. i

3. A chaplet eomprisingr-a'lower-member having grooveld supports oflnlnequal heightl rising therefrom, and an upper member having a depending standard adapted to engage one of said supports.

f4. A chaplet Comprising a lower plate,

grooved support rising therefrom, an upu per Yplate having a pair of parallel members depending therefrom and adapted to t over said'grooved rsupport and engage the groove therein, and a connection between said mem- 3G bers to rest upon saidsupport.

5. A ehaplet comprising a lower member, a supporttherefor and having a stepped kupper edge, and an upper member con- Copies of this'patent mayibeibbtaine'dfor ve cents each, byy addressing the Commissioner flatents, "Washngton,`1). G.
