GHAPLET.

Application filed August 23, 192B. Serial No. 130,837.

The present invention relates to chaplets used in connection with molding operations for positioning and supporting a core in place in the cavity in the mold.

.lteference should be had. to the accompanying drawings forming a part of this specihcation, in which I Fig. 1 is an elevation oi a chaplet;

Fig. 2 also an elevation takenin the position at right angles to that shown in Fig. lg

Fig. 8 is a top plan view of chaplet with portion shown in dotted line;

Fig. 4 is a section on the line l4t of Fig. 2;

Fig. 5 is and I Figs. 6, 7 and 8 are modified iiorms oi the ob aplet.

As is Well known, chaplets are used position and support a core in the cavity in the mold and when iron is introduced into the mold the iron flows around the body of the chaplet incorporating the chap'let as a part of the body of the iron, so that the chaplet 1s burnt in to the body of the iron.

When the casting is removed from the mold, any protruding portions of the chaplet are removed by chipping the same or otherwise and it is frequently found that the chaplet has not become completely burnt in to the body of iron so that the chaplet is more or less surrounded by a small cavity in the body of the iron itself.

Under such circumstances, it common practice to pean the chaplet so that it is spread slightly to till up the cavity in the iron and to produce a smooth and finished surface for the casting.

The present invention is directed to a form of Chaplet which is incorporated into the body of metal forming the casting in such manner that it peaning is required, the chaplct itself will be so incorporated in the body of metal as to have a firm anchorage therein permitting the peaning action without danger of driving the chaplet through the wall of the asting. In fact, when the chaplet is peaned a wedging action takes place which causes the metal oi the chaplet to completely fill in the cavity in the wall of the casting.

Referring to the drawings, 1 and 2 indicate the end members of the Chaplet, while the connecting a section on the line 55 of Fig. 2,

portion is represented at 3. This connecting portion is formed with broad reentrant grooves, such as indicated at 4 and 5, and in the forming of these grooves, which preferably is done by a swaging action, the opposite sides of the connecting portion 3 are slightly bulged outward at the center as indicated at 6 and 7. I

When, therefore, this chaplet becomes illcorporated in the metal of a casting, there will be metal occupying the grooves l and 5. There will also be metal surrounding the bulged portion of the connecting member 3. This will give a firm anchorage for the chaplet in the metal. of the casting.

Additionally, if peaning is required, the compression oi the metal on the" chaplet will tend to wedge it into any cavity or spaces that may sari-(mud the chaplet, thereby giving the chaplct a firmer and more complete incorporation in the metal. of the casting.

in Figs. 6, 7 and 8, a modified form of the chaplet is shown, comprising the end members 1 and 2 with a central connecting portion 3*. The grooves l and 5 are provided as well as the bulged portions G and 7. In addition the recesses are traversed by ribs 8 and 9, which give slightly more metal. atwhat would otherwise be the thin cross-section of the central member oi the chaplet, thereby preventing the n'iolten metal as it contacts with the chaplet from burning through the body oi the chaplct.

All the advantages which have been heretofore described are maintained in the modiiiedfforin of chaplet, with the additional provision of the ribs which prevent the metal burning through the body of the chaplet.

Having thus described my invention, I claim- 1. A Chaplet comprising substantially flat end meu'ibers, a connecting body portion, opposite parts of said body portion being formed with re-cntrant grooves, said body portion having longitudinal extending ribs at substantially the central portions of said re-entrant grooves, the said. body portion also being bulged outwardly at points intermediate the said grooves.

2. A chaplet comprising substantially flat end members and a connecting body portion, said body portion being formed with oppositely disposed reentrant grooves and havbody portion having transversely extending ing longitudinally extending rib members reentrant grooves formed therein, and longi- 10 formedin the body portion and substantially tudinally extending rib members formed in at the central portion of said grooves, the the'body portion and substantially at the cencross sectional area of the body portion being tral portion of said grooves.

substantially uniform'throughout its extent. In testimony whereof, I hereunto afiix my 3. A Chaplet oomprising'substantially end signature.

7 members and a connecting body portion, said CHARLES GREIF RAIBLE.
