General Description.
three 'steps or changes, cc' a. i
B is a grinding-wheel, which may be of emery or It is journaled in the surroundingr for the collection of scrapings from the wheel and waterplgii' necessary. One side of the case is detachable, inf` order to provide for thcrcmoval of the dust or scrapin gs.
lhellwheel B is driven by theV wheel 1), which has a driving connection, by friction only, with the intermediate wheel E,j which, in its turn, connects by friction wit-h the` cone of the lathe A.
The wheel E is grooved in its face, and tted with a ring'of leather or rubber, Ii, which is provided to increase theii'iction and-prevent slipping. The wheel E is connected by suitable spindle to the case G.
JAMES snAUeHNnssY,
A il; the `cone-pulley of a lathe, having, in thiscase,
, ,Letters Patent No. 103,242, mail May 17, 1ste.
The case C is formed with a dovetail slide, c,lon'the underside, which tits and slides in the dovetail ways g g of' the frame G. The direction of mot-ion of the.`
H H', which may either impinge directly uppn the'` slide or upon the intermediate gib I.
The jaw g of the frame G tits over the bar J, along which it Vis adapted to slide for adjustability. It is secured in any position by set-screw K.
It will be readily seen that, owing to the provision of the ,sliding devices described, the wheel E can be brought into frictional contact with either oi' the steps a a c" of' the cone A, in order to change the speed of the wheel B, or avoid conflicty with the drivinghelt ot' the lathe. l
lThe bar J, which is formed with legs j, rests upon the shear L of the lathe, arid is secured firmly by set-screw bolts M.
The'case G is provided with a gap, N, i'oi the accommodation of the tool to be ground.
It is well4 known that, in an ordinarymachine-shop, a great amount ot' time is wasted by the shop-hands in running to and `from the grindstone, to merely touch up the points of lathe-tools, and myinvention is designed to remedy this diiiculty, and furnish a very convenient andihigh-speed stone o1' Wheel for all the grinding required by a lathe-hand, except, perhaps, roughing oii'.
Claim. I claim ns new and of my invention- 'Ihe herein-described tool-grinding attachment to lathes, composed of wheel or stone B,sliding case/C e, sliding frame G q g g V 1I H, bar J, and driving..
friction-wheels D E; the wholeA being constructed and combined substantially in the manner and for thepurposespeciiied.
In testimony of' which invention I hereunto set my4 hand.
