.coALl'poR ROCK DRILL.;

SPECIFICATION forming part of Letters PatentNo. 683,628, dated October 1, 1901- Applieetion filed June 8, 1901.

provementsin Coal or Rock Drills; and I doV hereby declare that the following is a full,

clear, and exactdescription of the invention,

which will enable others skilled in the art to x .l which it appertains to make and use the same.

This invention has reference to coal or rock drills, and especially to that class of drill known as a grip-drill. I

. The object which I have in View is to provide a drill comprising a boxing of two hinged sections with a depending seinicircular body portion having a notched edge, and a gripbar attachment-havin g a pivotal relation with the lower section of the hinged boxing and 2o supporting a gripbar arranged.to be locked to'said attachment.

The invention consists, further, of anancher, to which the forward end of the grip-bar maybe detachably secured for supporting the same, said anchor purposed to be first driven into the material to be worked and then attaching the grip-bar thereto, forming a supv port for the drill and holding the auger thereof to its work.

3o Theinvention consists in various details of construction and arrangement of parts hereinafter more fully described, and pointed out 4in the appended claims, due reference being y had to the accompanying drawings, forming a part of this specification, in which- Figure I is a drill, shown in elevation, embodying my improvements. Fig. 2 shows a plan, enlarged, of the boxing and grip-bar attachment. Fig. 43 is an elevation of Fig. 2.'

4o Fig. 4 isa side elevation of one side of Fig. 2. Fig. 5 shows a cross-section of the grip-bar attachment. Fig. 6 vis a perspective View of the anchor. Fig. 7 is a cross-section through the same, showing certain details; and Fig.

8 is an elevation', partly in section, of the support for the rear end of the grip-bar.

In the drawings like numerals refer to corresponding parts throughout the ligures The drill comprises two half-boxings I and 5o 2, hinged together at 3, the n ut thereof formed of semicircular threaded linings suitably secured inthe half-boxings. The'boxing 2 has Serial No. 63,717. (No-model.)

the laterally-extended arm 4 with tubular bearing 5 arranged to support power mechanism, which comprises a stem journaled in the bearing carrying a bevel-gear 6, intermeshing with a bevel-gear 7, carried by the thread- bar 8, and 9 is a crank for actuating f thejthread bar through such power mechanism.

Depending from the lower half-boxing I provide a semicircular extension l0 anda tubular bearing l1, said bearing arranged transversely to the movement of the thread-bar, and 12is an aperture therein. This semicircular extension 10 of the boxing is arranged in an arc whose radius is struck from the center ofthe aperture I2, and the lower edge or face ofthe extension is provided with notches, as 13, which are substantially V-shaped for a purpose to be described.

14 is a yoke having'a rectangular body p0rtion 15, with a rectangular opening 16 through the same, and 1 7 shows diverging arms of the yoke with apertures 18. This yoke is arranged to span the extended and flared portion of the lower half-boxin g and be attached thereto by means of a pin or similar device, which is slipped through the apertures I8 and tubular bearing Il of the boxing. The yoke is designed to carry a grip-bar I9, which in this instance is a hollow' rectangular bar in size adapted to 'fit snugly the rectangular opening 1G in the yoke, and one edge of the bar is provided with a series of serrations 20, as shown. Thus it is that when the bar is slipped through the opening IG and the yoke is made to span the lower half-boxing, substantially as is illustrated in Fig. 3, a yokepin 21, having the portions 22 and 23, is used .for locking not only'the yoke to the boxing,

butthe grip-bar to the yoke. The extension 22 of the yoke-pin 2l is slipped through the extensions I7 and tubular bearing I1, and the extension 23 of said pin is slipped through an aperture 24, arranged inthe yoke, which cuts through the rectangular body in such a manner that the pin 23 will engage a serration of thegrip-bar and a'notch in the lower edge of the sem'icircular extension of the boxing. The extension 23 of the yoke-pin in cross-section has the rounded lowerportion 25 and the V-shaped upper portion 26. This IOO arrangement willpermit of a greater number of notches in the extension 10 than could be provided by the use of serrations such as used in the grip-bar and permit of the drill being adjusted to a greater number of positions.

27 refers to an anchor-shoe having the tapered or Wedge' portion 28 and the portions 29 and 30, the portion 30 extending'beyond the bodyportion 29 a suitable distance and provided with a rectangular socket 3l therein, and 32 is an aperture vpassing through the anchor, as shown. In drilling coal or other material it is necessary to support and brace the grip-bar in a positive manner. This has been done heretofore in various Ways; but I am not aware that au anchor of the character described'has ever been used which may be first driven into the' material and then fastening the grip-bar to the same. This is accomplished as follows: The provision of the Wedge makes it easy to hammer it into the coal or roclnandvthe provision of the olfsct 29 Iof the anchor provides a seat by which the same may be hammered into the material, and when securely fastened therein the end of the grip-bar may be inserted into the socket 31 of the extension 30, and the bar havingan aperture 33 through the same a pinv or similar device 34 is dropped through the aperture 32 and through the aperture 33 ofthe bar, which locks it rmly to the anchor.

While I havevshown that thegrip-bar is detachably connected to the anchor by being inserted in the notch 3l, it is to be understood that the extension 30 may be so arranged that it may be inserted into the grip-bar and locked instead of the bar being insl red into the socket 31.

The manner of coupling the boxings and yoke makes it possible to shift the boxing and drill-rod to any angle coming in range of the movement of the semicireular extension thereof. vAs it will be seen, the grip-bar is firmly secsred in the coal or rock. By removing the4 yoke-pin, so that the extension 23 is free of the yoke and boxing, the drill-rod may be moved to a suitable angle, as the boxing is free to swing on the extension 22 of the yoke-pin, and when in position the eX- tension 23 may be again made to engage the aperture 24 and the yoke and 4corresponding notch in the semi'circular extension of the boxing, which locks the parts firmly together in the manner shown.

' By supporting the drill on a bar-of the character shown it has the advantage after the thread-bar has been advanced in the feednut its length toppen the upper section of the hinged boxing and advance Athe boxin'g on the grip-baruntil the nut again engages the forward end of the threaded bar and the drill is in positionv to,l advance the auger its 'full length -into the coal or rock when ad-v j usted at proper angles.

I have provided a novel support for the rear end of the grip-bar, which comprises a support 35, having a rectangular bearing 36 to be slipped over the rear end of the bar in the manner shown in Fig. 1' and tied to the same by means of a pin 37j or similar device, passing through an aperture 3S in the support and a serration of the bar, and extending down from the bearing is shown a perforated bar or rod 3D, telescoping into a support 40, with bifurcated extensions 4l, the same held in adjusted positions on the bar 39 by a pin 42, passing through the support 40 and bar 39.

Diverging'from the upper face'of the bearing 36 is shown a frame ofbifurcated sections 42, arranged to straddle. the thread-bar and centering into a common spindle 43, which is threaded and provided with a hand-wheel 44, and telescoping onto the spindle is a movable section 45, adjustableby the movement of the hand-wheel, substantially as shown in the drawings.

I do not Wish to be limited to the details of construction and arrangement of parts as herein described and illustrated, as it is obvious that various changes may be made in the construction of parts as to details Without affecting the principle and scope of invention herein. i

Having thus fully described my invention, WhatI claim, and desire to secure by Letters Patent of the United States, is-

y l.
