Specification of Letters Patent.
Patented Feb. 12, 196?.
Application filed January 17,1906. Serial No. 298,501.
'bodiment of my invention. Fig. 4 is a pers ective view of a planer-knife, provided a ong its cutting edge with a rabloet and illustrating a class of work for Whichthe invention is especially adopted.
This invention relates to grinding-inachines, and has for its object the forming of grooves or rabbets in the edges of bars and more particularly in planing-knives.
The invention consists in the novel construction, adaptation, and combination of devices as will be hereinafter described in connection with the said drawings.
The frame of the machine comprises a bedplate 5, a standard 6, which supports in suit able journal-boxes an arbor 7, carrying a pulley 8 for adriving-bclt, and two flangecollers 9, whereby an emery-wheel 10 is do-- tachably mounted upon the arbor.
Slidebly secured to the frame-standard is e work-bed 11, which is adjustablywaised or lowered by means of a sore v 12, passing through an in ternally-screwthreaded boss 13, formed or provided upon the stid bed, The bed is retained at the requisite vertical position by menus of jam-nuts upon the said screw or desirably by a clamping-bolt, such as 14, passing through sperturfed cars of the bed. At or near the front edge of the bed is, a. trunsverslyerranged rib 1:6, having oppositelydnclined front and back edges 16,
which fits into a correspondingly-shaped re I cessi Not a workdeble 18 and forms a guide therefor. A reciprocating traverse motion is communicated to this table by suitable means, such as a rack 19, provided thereon, being engaged by a pinion 20, mounted upon a spindle 21, whiohis journnled in boxes 22, carried by said bed, and rotated by a. crank 23.
Attached to the upper face of the lied is a face-plate 24, provided with rectangular flanges 25, having slots 26, through which pass the retaining-bolts 27, which e'ngege in threaded holes therefor in thetcp face of said carriage and is edjustably moved by setscrews 28, which extend through lugs .29 of the carriage end haying their ends beer against said faceiste or upon the work cured thereto. the face-plate is likewise rovided with horizontal slots for the olts 31 with which the Work is secured in place and Where planerdtnives, such as P, are being operated upon also pass through-the slots 32 oi the latter. I
The knives or other work being secured to the face-plate and adjusted in a horizontal and vertical direction by moving the latter and the bed, as before explained, the carriage is then moved b manipulating the crank 23 backward and orward beneath the driven emery-Wheel to effect the desired out upon the knives and grind out the rabbcts 34 thereof. Where the wheel is of the proper thickness, twokni-ves can be 0 positely secured to the fecelat'eend groun simultaneously.
The at vantages of the invention reside in the facility with which knives or the like may be odjustahly set and accurately ground, in the simplicity or the mechonisni, and in the relatively low cost of construction.
Having described my invention, Wile-t1 claim as new, and desire to secure by Letters Patent, is-
In combination with abed of a grindingmachine, it Work-table, e face-plate composed of rectangular side flanges, and e'v'ertioally extending part, said flanges being clamped to said table, upwardly-projecting lugs bythe table, set-screws extending through said lugs and bearing against seid central part of the face-plate on opposite sides thereof, said central part being slotted to receive means to clamp the work thereto.
In testimony whereof I aifix my signeture in presence of tn o-witnesrses.
JOHN T. WHEATMAN.
