DRILL-BIT PULLER.

Specification of Letters Patent.
Patented Apr. 16., 1918.
Application filed January 4, 1917. Serial No. 140,616.
the, county of Cochise and State of Arizona, have invented certain new and useful Improvements in Drill Bit Pullers, of
which the following is a specification.
This invention relates to an improved drill bit puller and the principal ,object of the invention is to provide a puller which can-be connected with the drill socket and;
with the bit or steel and which will be so constructed that when it is desired to extract the bit, this may be easily done through the medium of the puller.
Another object of the invention is to so construct this puller that it may be connected with the bit or steel and while it will not interfere with the bit when drilling, will obtain a firm grip thereon when extracting the bit.
This invention is illustrated iii the accompanying drawings, wherein Figure 1 is a view in elevation showing a drill'in use with the puller connected with the bit and drill socket or brace.
Fig. 2- is a view of the puller before being put in place.
The drill brace indicated in general by the numeral 10 indicates a conventional type of brace such as is commonly used for rock drilling and include"; a socket 11 into which fits the bit or drilling steel 12 which will also be of a conventional construction. The puller is provided with a collar indicated in general by the numeral 18 in Fig. 1 and shown in detail in Fig. 2. This collar is formed of two sections 14: which are pivotally connected as shown at 15 and have their free end portions provided with outstand ng ears or fingers 16 connected by a bolt 17 so that the collar may be secured in place as shown in Fig. 1. A chain 18 which may be termed a cable or flexible connection is carried by the bolt 17 and carries a gripping ring 19 which is split as shown at 20 so that the ring may he put in place upon the drill steel 12.
- When in use, this puller is put in place as shown in Fig. l with the collar engaging the socket and the gripping ring mounted upon the bit or drilling steel. The drill will be driven in the usual manner until the bit has drilled a hole in the rock, the desired depth, water being of course poured into the hole to soften the rock and make the drilling easier. During the drilling process, the powdered rock mlxes with the water and forms a paste which collects about the drill steel within the hole and as this cakes about the drill steel, it often makes it exceedingly difficult to extract the bit after the drilling is completed. With this device in use, the
socket orbrace can be disconnected from the bit and the bit can then be easily pulled out of the hole by means of the puller. When the puller is drawn toward the outer end of the bit, the ring 19 will be turned so that it will have a friction grip upon the bit or drill steel and there will therefore be no danger of the puller slipping off of the steel when in use while at the same time, this construction permits the puller to be easily put in place and not interfere with the proper action of the drill steel while drilling the hole. It will thus be seen that there has been provided a very eflicient puller so conportion connected with said split ring and its opposite end portion engaged by the fastener.
In testimony whereof I aifix my signature in presence of two witnesses.
