JOHN L. oTIS, OF LEEDS, MASSACHUSETTS.
IMPROVEMENT IN GRINDING4MACHINES.
-, Specification'forming part of Letters Patent No. 182,284., dated September 19, 1876; application filed July 10,1876. I
To all whom it may concern:
Be it known that I, J OHN L. 011s, of Leeds, in the county of Hampshire and State of Massachusetts, have invented certain new and' useful Improvements pertaining to a Grinding-Machine, of which the followingis a specification, reference being had to the accompanying drawings, where- Figure 1 is a top view. Fig. 2 is a side view. Fig. 3 is an end view. Fig. 4 is a par tial section on plane a: .90. Fig. 5 is a section of the grinding-wheel. Fig.6 is a view of a planer-knife such asthe machine grinds.
I will first describe the machine, and then specify the features of invention in the claims.
The letter a denotes the table; b, awaysblock pivoted thereon by means of pin or screw 0. lengthwise of the Ways-block, its reciprocations given by the pit-man e pivoted to the rotating disk f. g denotes a rest-block, moved toward and from the grinding-Wheel by the screw it. 1) denotes a rest pivoted to the rest-block, partially rotatory, its angle of adjustment to the grinding-wheel governed 'by'the arm j moving on the rack is, which is slotted andpierced' bythe set-screw Z. m denotes a. planer-knife under process of being ground to an edge, being fastened meanwhile to the rest by headed screws n n piercing the mortises in the planerknife and in the rest, and bearing the thumbnuts 0 0. The letters pp denote a gage pivoted to the rest andcapable of swinging up, as shown in Fig. 2, to regulate the setting of cl denotes a slide, reciprocating stock, relatively to the grinder, can be adjusted at pleasure, thus determining at pleasure the concavity of the bevel which forms one side of the edge.
Another feature of the invention consists in the wheel and gages combined With the rest,
and operating to allow the user to set the knife to position for grinding by its edge.
1 claim as my invention- 1. In combination, a flanged grinding-wheel,
1', a rest, 2', traveling across the grinding-face thereof, and a ways-block, b, pivotally adjustable with reference to such grinding-face, all
substantially as described, and for the purpose set forth.
2. In combination, the grinding-wheel 1', the rest 71, and the pivoted gage 1), moving on and 011' the edge'of the blade to be sharpened, all substantially as described.
JOHN L. OTIS.
