"3 Claims.
This invention is directed broadly toan improved method for setting stones and to an improved construction of mould for use in the practice of my method, the invention more specifically relating to settingthe cutting stones oi diamond tool holders.
In the making of diamond tools as heretofore practiced, dimculty has been experienced in holding the cutting stone or diamond against displacement during the casting of the metal oi the holder about the same. The diamond. too, is
This causes disintegration and at times tool. v y I I purpose to overcome the culties above referred to and to provide a very much improved product by temporarily holding the diamond oi the 1-:
m of the stone against displacement and protecting these oi the holder the against burning by surrounding the diond with an inert gas which is caused to flow. past the diamond during the operation of w the metal oiv the holder about the diamond.
In the accompanying drawing wherein I vs illustrated one io of mould capable of use in the practice of my invention: -liig. l-is a secnal elevational view oi the mould showing the diamond in place therein:
Fig. 2 shows the holder with the diamond set therein as it appears when removed from the mould; and
Fig. 3 is a section on the line i-ioi Fig. 1. Referring to the drawing in detail: i designates a mould, provided with mould cavity t which may '1 be oi-any shape desired, as'will be understo.
In the bottom of the mould cavity I provide an orifice B for the reception oi the cutting stone i during the operation oi easting the holder about the stone. x
As above pointed out, one of the objects oi my invention is to provide simple and emcient means ior temporarily holding the stone in the mould so that during the operation of pouring the metal will not be burned or. overheated.
with the stone resting in the orifice-a current of inert fluid can be forced past the stone to hold the same against displacement with respect to l Communicating with the orifice 6 is a auction (01. 22-202) Y In addition to the suction line ii a line limits the stone ior use as a cutting stone will not be displaced and hs will be seen from the drawing, the orifice i isnot otthe same shape as the stone i, so that one In. it leads to the mould, and is in communication with a channel II in to a. supply of inert gas such as the stone will be surrounded by a current oi inert gas to protect the stone against injury by the heat oi the molten'nietal andto hold the stone in the orifice against displacement operation. 1 v
It will be understood oi course that aiter the holder is removed from the mould it in. he turned down or otherwiseshaped to any iorm desired. a
It will be seen irom all oi the foregoing that I have provided an improved method oi and apparatus ior setting out. stones wherein I have provided an exceedingly simple arrangement for holding. the stone against displacement and ior protecting the stone during the moulding or castlng operation.
It is to he understood that bhanges may be made in the dot of construtcion and arrangement oi parts hereinabove illustrated and described with'outdei I i iroin the spirit and scope of invention.
at I claim is:
1 I. In the setti oi. diamonds in a diond tool holder, the me diamond oi irregular shape into engagement with the wall oi an opening oi a diilereut shape in a mould and owing an inertfluld about the diamond and throughthe opening while pouring the metal of thesetting into the mould to prevent.
the mould, and'a channel 'i t leading therefrom to the top oi the mould cavity.
parts in place suction is during the casting m which comprises inserting a stone and through the orifice to envelop the stone" intheinert gas and hold the stone against displacement while pouring the metal of the holder into the mould cavity.
'3. A mould for the setting of cutting stones in a holder, comprising in combination a mould cavity having an orifice in the bottom thereof for the reception of a cutting stone of irregular shape, a suction line communicating with the mould cavity through said opening, and means for supplying an inert gas to the mould cavity to
