To all whom it may concern:
Be it known that I, WILLIAM PARR LIGHT? BODY, a subject of the King of Great Britain,
a resident of Langlaagte Deep, (Box 1 056,) Johannesburg, Transvaal, but at pres ent of Beehive Works, Bolton, in the county of Lancaster, England, have invented certain new and useful Improvements in Mechof which the following description, together with the accompanying sheets of drawings, is
My invention relates to improvementsin mechanism for use in the process of sharpening rock-drills of the class wherein the cutting edges converge so that they form a kind they are formed having three or four Wings'or' ribs. In rock-drills of this description the raproportion to their lengths. Thus a short it is in the production of devices for connecting together the dollying mechanism roperly is held are adjustable, so as to accommodate drills'of different lengths) and swaging mechanism for acting upon the sides of .thewings or ribs,
thereby to the proper dimensions relatively In the accompanying sheets of drawings, which are illustrative of my said invention, Figurel is a side elevation of dollying and swaging apparatus for treating rock-drills and my improved devices for connecting these arts together. Fig. 2 is a side elevation tllereof as seen in the opposite direction 1 4 is a plan of the levers and other parts f r connecting the dollying and swaging mechanisms together. Fig. 5 is a side elevation of certain of the parts illustrated by Fig. 4. Fig.

the opposite'end of said drill the opening 9' and against the face ofthe anthe-nut 12. The screw 11 is rotated by the hand-wheel 13 dimensions required in Patented. March 20, 1906.
or die 2, which is mounted in bearings and v drill 8 as it is being acted'upon by this device has-one end supportedin the dolly-bearing,
takin within chorage or holder ,10, and in order that varied sizes of drills may be acted upon this .anchorageor holder 10 is moved nearer to or, farther from'the dolly 2, the bearing of the latter serving asa stop when the end of the drill abuts thereagainst, the adjustment of anchorage or holder 10 beingefl ected by the rotation of the screw 11, which meshes with '(Shown in broken lines, Fig. 3.)
and bevel- gears 14 and 15. v
The swaging mechanism illustrated by the drawings consists of a series of swages 16, which are mounted in radially-movable blocks 17, provided with caps 18, which are held, by
means of 'springs 19,-in contactwith the inner surface of the ring 20, the parts 21 of which are cam-shaped, and'(as the ring 20 isrotated by its driving-shaft 22 and pulley 23) impart the 'reciprocatorymovements to the blocks 17. The inner surface of the cam-ring 20 is also inclined in an axial or longitudinal direction, so that as it is moved longitudinally or axially it transmits varied movements to the I swages '16. These longitudinal and rotary movements of the shaft 22 and ring 20 are allowed by said shaft being connected to its driving-pulley 23 by feathers and keyways.
The essential feature ofmy invention is to provide means which as the anchorage or holder 10 is adjusted by means of the screw 11'to accommodate varied lengths of drills the cam-ring 20 is or may be simultaneously trunnions 3 1) the casing 32. Within said -moved, thereby adjusting it to such a posiin'bearings 29 on the IIO (by the pins or casing is mounted the spring 33, its outer end taking against the flange 34 of the sleeve 35, which passes through said spring and casing and is provided with nuts 36. Inside the sleeve 35 is a pin or shaft 37, which is connected to the lever 38, fulcrumed at 39 in bearings 40 on the framework D, its outer ends 41 carrying bowls 42, which take between flanges 44 on the shaft 22. By these means the rotary motions of the screw 24 transmit a longitudinal movement in a backward or forward direction to the shaft 22 and cam-ring 20, these movements being always in pro er relation to those of the anchorage 10. s this longitudinal movement is transmitted through the spring device 33 34, &c., should the swages 16 not be able to swage or bring the drill down to its proper dimensions quickly (in which case the rotary motions of the ring 20 might be arrested) this spring device may yield and allow the swaging operations to be performed gradually.
The lever 27 is formed in two parts held in position by a bolt 45, (see Fig. 5,) so that when desired these may be separated and the adjusting mechanism thrown out of action.
Having thus described the nature and obj eet of my said invention, what I claim is l. A machine of the character described comprising radiallyarranged swaging de vices, a rotatable cam-ring for operating the same, means for reciprocating said ring, an adjustable drill-support, and connections between said drill-support and said reciprocating means, whereby the latter is controlled by the adjustment of the former.
2. A machine of the character described comprising radiallyarranged swaging devices, a rotatable cam-ring for operating the same, a yielding device for reciprocating said ring, an adjustable drill-support, and connections between said drill=support and said yielding device, whereby the latter is controlled by the former.
3. A machine of the character described. 45 comprising radially-arranged 'swaging devices, a rotatable cam-ring surrounding the same, a lever adapted to reciprocate said ring,
a cushion for said lever, an adjustable drillsupport, and connections between said drillsupport and said lever, whereby the latter is controlled by the former.
4. A machine of the character described comprising radially-arranged swaging devices, a rotatable cam-ring for operating the same, a rock-shaft having an arm, a casing mounted on said arm, a lever adapted to re-a, ciprocate said ring, a spring in said casin -w bearing against said lever, an adjustable drillsupport, and connections between said drillsupport and said rock-shaft.
5. A machine of the character described comprising radially-arranged swaging devices, a rotatable cam-ring surrounding the same, a rockshaft, a lever operated thereby and adapted to reciprocate said cam-ring, an adjustable drill-support, and connections between the drill-support and said rockshaft.
6. A machine of the character described comprising radially-arranged swaging devices, a rotatable cam-ring surrounding the same, a rock-shaft, a lever operated thereby and adapted to reciprocate said ring, a drillsupport, an adjusting-shaft therefor, and connections between said shaft and said rockshaft.
In testimony whereof I have a'llixed my signature in presence of two witnesses.
WILLIAM PARR LIGHTBODY.
