Welded Double Head Chaplets
 

Ordinarily, chaplets are used to support a core from the bottom, or to anchor it from the top to prevent floating. However, it is quite as important to secure it against lateral shifting due to unequal pressure of the metal while pouring. This is frequently done by wedging a double headed chaplet between the mold and the core (or between two cores), using shims where necessary to provide a tight fit, or by tilting the heads of a one piece chaplet and using it as a wedge. In either case, the chaplet must necessarily be placed after the core has been set, and is held in place by friction only. Such cumbersome and uncertain practices can be eliminated by the use of one of the chaplets shown in sketches on this page.
Square double headed with staggered heads (one head rotated 45 degrees) and Nail Holes, by means of which the chaplet can be securely fastened to the side of the mold or core before the latter is set.
A double headed chaplet with extended stem used in the same manner as the square double headed chaplet with staggered heads.
A long double headed chaplet is rammed up through the core with one head protruding on either side – another positive method of preventing the chaplet from falling and the core from shifting.
A somewhat similar condition is successfully met with this unique chaplet having three heads and two stems. Here a wedge shaped core is securely held in place without danger of shifts due to chaplet slippage.
Double headed chaplets with extra thin heads can be furnished when it is desirable for the sake of the appearance of the finished casting, to set the chaplet in a shallow boss and remove the head by grinding. We can furnish chaplets up to 1” high with 1/4 ” stems and 1” heads of 22 ga. steel. The use of this thin headed chaplet makes less grinding necessary.
This double headed chaplet with one large and one small head solves a two-fold problem in the type of casting as illustrated. The large head provides ample support on the core side to prevent “rocking.” The small head is cast in a boss on the drag surface. As this surface is machined later, the small size of the head material reduces machining time.
Stem chaplets are usually used to anchor a core from the top, however, pointed end stem chaplets can be used to support a heavy core from the bottom provided the pointed ends are being driven into the bottom boards to provide secure anchorage.
Here we have a single head threaded stem chaplet used in the same manner as a radiator chaplet. This type can be furnished with oversized heads for better support. The threaded stem insures sound pressure proof castings.
A double headed chaplet with one curved and one flat head is used here to support a cylindrical core which is anchored from above with a curved head stem chaplet. Both heads can be curved to different radii for use on pipe castings and in different directions when desirable. See the highly specialized chaplet pictured above.
In this application a radiator chaplet with a comparatively heavy stem is used as a chill to prevent internal shrinkage. Note how the shoulder properly gauges the section of the chaplet stem that extends into the cavity of the mold.
