FEED MECHANISM FOR KNIFE-GRINDING MACHINES.
SPECIFICATION forming part of Letters Patent No.448,616, dated March 17, 1891..
Application filed July 14, 1890. Serial No. 358,639. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES E. Henson, of Leominster, in the county of lVorcester, State of lllassachusetts, have invented certain new and useful Improvements in Feed Mechanism for Knife-Grinding Machines, of which the followingisadescription sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a front elevation of a grindinginachine provided with my improvement; Fig. 2, a sectional end elevation enlarged, and Fig. 3 a sectional elevation illustrating certain modifications.
Like letters and figures of reference inclicate corresponding parts in the different figures of the drawings.
My invention relates especially to an automatic feed device for knife-grinding machines; and it consists in certain novel features hereinafter fullyset forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the body of the machine, which consists, primarily, of a table orbed I), mounted on a standard d. The table is grooved horizontally, forming ways f, in which a carriage B is fitted to slide in the usual manner of machines of this class. An ordinary rotary grinder-wheel K is mounted on a shaft journaled in standards hon the body, said shaft bearing a fast pulley -1I and a loose pulley j. A knife-carrier D is secured on a shaft mounted in bearings 7; on the carriage B. The carrier is grooved longitudinally in its upper edge to receive the blades II. Hand-screws m, passing through a flange or lug p on the carrier, secure said knives in the grooves. The carrier is preferably arranged to fall inward toward the wheel K, and is of sufficient weight to hold the bladeedges firmly against the grinding-face of. the
wheel. A screw 0' is turned into a vertical socket t on the carriage B, and is in position to engage a boss or stud e on the carrielysald screw serving as a stop to determine the ineline of said carrier. This stop may, however, be of any construction desired and arranged in any suitable position. 1-Iorizontally:arranged screws or: z are respectively turned into the tops of the wheel-standards 7t, theirlieads being slightly within the periphery line of said wheel, and in position to be engaged by the edge of the blades 11 after the carrier O passes the face of the wheel. The screw oc, the head of which is partially shown in Fig. 1, is secured in the standard h at the side of the wheel K opposite that in which the screw .2 is disposed, said screws occupying the same relative position in relation to the wheel.
In the use of myimprovementthe blades II are clamped in the carrier D. The screw 0' 1s then adjusted in relation to the stud '0 maccordance with the amount necessary to grind from said blades. The weight of the carrier holds the blades in engagement with the grinding-face of the wheel K, which acts thereon, the carriage B reciprocating in the ordinary manner of machines of this class. The serpws 0c .2 are adjusted in relation to the wheel It, so that the distance from their heads to the face of the wheel shall determine the amount to be ground from the blades at each passage of the carriage. The carriage advancing until the carrier has passed the wheel K, the blades fall against the head of a screwm or 2, and on the return of said carriage said blade engages the side of the grinder, removing a portlon of the blades proportionate to the distance between the screw-heads and face of the wheel K in a manner which will be readily understood without a more explicit description.
In Fig. 3 a modification in the manner of mounting the screws 00 is shown. An angle iron 15 is bolted to the wheel-standards, and is provided with a longitudinal slot 16. A similar iron 17, having a head is, is LClJL1Stably secured to the iron 15 by a bolt 19 passing through said slot. The screws 00 or are turned into the iron heads 18.
Having thus explained my invention, what I claim is 1. In a grinding-machine, a stop disposed at each side of the grinding-wheel in position to be engaged by the blades, snbst an tially as and for the purpose set forth.
2. An automatiefeeddeviceforknife-grinding machines, compri ing adjustable stops mounted on the machine-frame adjacent to the Working-face of the grinder and in position to be engaged by the blades as they pass said grinder, substantially as described.
3. Ina device of the character described, the combination of the grinding-Wheel and reciprocating carriage With a tilting bladecarrier on said carriage, a stop for said carrier, and stops disposed adjacent to said Wheel for determining the fall of the carrier at each re ciprocation of the carriage, substantially as described.
4. In a device of the character described, the rotary grinding-wheel and adjustable blade-stops, in combination with a horizontally-reciprocating carriage, a gravity bladecarrier pivoted thereon, and an adjustable stop for said carrier, substantially as described.
5. The Wheel K and adjustable stops as 2', in combination with the reciprocating carriage B, provided with the adjustable stop 1', and the blade-carrier D, pivoted on said carriage.
