GRXNDING' AIM D POLISHING MACHINE.
No. ceases.
To all whom it may concern:
Be it known that I, JAMEs M. THOMPSON, a citizen of the United States, and resident of North. Milwaukee, in the county of Mil- Waukee and State of Wisconsin, have invented certain new and useful Improvements in Grinding and Polishing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.
The object of myinvention is to provide a simple, economical and effective grinding and polishing machine for edged tools or the its parts being such that it may readily be assembled, and adjusted for different classes work. Said invention therefore consists in certain peculiarities of construction and combination of parts as hereinafter fully set forth with reference to the accompanying drawings and subsequently claimed.
in the drawings: Figure 1 represents a front elevation of a grinding-machine embodying the features of my invention, with parts broken away to better illustrate the details of construction; Fig. 2, a side elevation of the same, parts being broken away and in section, indicated by line 22 of Fig. i; Fig. 3, a rear elevation of the grinder frame with the abrading-w'heel in position,
the driv ung'ears being removed; Fig. 4, a detail s-section of the hand -crank at- "u-hing means, indicated by line 44 of Fig. '1; Fig. 5, a detail section on line 55 3, showing the ad ustable tool-rest,
' a sprcckebwhccl C, said sprocket being connected by a huh-belt d to a smaller sprocket wheel D fasten a shaft E, that is supported in bearings 4 ,7", of a bracket G as shown. A hub-extension of sprocket-wheel D has secured thereby an abra ling-wheel H, which wheel receives its motion from the described gears. The bracket G is formed with front and rear arms carrying the bearings e, f, said arms rising from a web 9, that is swiv- Specification of Letters Patent.

eled upon a bolt h, which bolt passes through the base A, and has a clamping-nut i that serves to hold the 'web against the face of said base. The bracket-web g is provided with a circumferential slot j for the reception of a lock-bolt K, which is carried by the base, and bymeans of which said bracket may be adjusted to regulate the tensionof the link-belt connection between the s )rock- The front face of the base A is siightly depressed for the reception of the leg of a depending clamping-foot I, through which leg the bolt it also passes and secures the same to said base, the foot portion of said leg beingprovided with a clamping screw K in threaded-connection therewith, whereby ble upon the top of which the supportingfeet a of the aforesaid base will rest. I
A circuniferentially supporting-plate J is loosely mounted u )on the inner end of the shaft-bearing f, and is held in its adjusted position by means of a bolt m. This bolt asses throu h the adjac nt arm of the brao et G and a so a circumi. ential slot in the plate, there being a nut 1. threadeihengagement with the bolt upon is face of the plate, whereby the same is camped. The u per edge of the plate is formed with an inclined fiat rib 0 upon which a toll may rest when it is desired to use the side surface of the abrading-wheel, and the outer end of said plate is slotted to receive a clamp-bolt p, which bolt has secured thereto a tool-rest Q that is pro vided for a work-support, when a knife or tool is to be ground upon the face of the wheel. The tool-rest or work-support has a flat face projecting across the width of the abrading-wheel and a right-angle ear 1 portion having a circular segmental slot through which the bolt 1) passes and is clamped by a nut s. Projecting over and resting upon a flat upper face of the. late J is a semicircular lug t, the axis of whic i is the same as that of the segmental slot of ear 1, of which the lug forms a part, and as best shown in Fig. 3, of the drawings. This lug will support the tool-rest at any angle that it may be set, thus permitting arolling motion of said tool-rest, which is compensated for by the circular slot moving about the bolt therein.
By the construction as described, it willbe understood that the plate J may be adjusted relation to the face of the abreding-wheel, and the tool-rest may also be adjusted in or out with relation to the face of said wheelby reason of its slotted connection with said toolwest and its bolt, thus compensating for various diameters oi grirnling-wheels caused through wear or otherwise. The shaft E is provided i 'ith a rear extension for the reception of e boiling-wheel as indicated by dotted lines in Pi 2, the end of said extension being threaded. tor the reception of e leek-nut 'ib, and is also provided with s split-pin v adjacent to its bearin f, against which the hub of the buil'mg-wheel is adapted to contact.
A hand-crank K is detaohebly secured to the driving gear-wheel B by it bolt w, which bolt clamps the hend-orsnk to it spoke of said geonwheel, the spoke being provided with a radial rib m that is nested intoe longitudinal recess of the said hand-crank, whereby all strain is taken from the bolt. The
lower end of the crank is provided with a hand-grip and its upper end'terniiimtes in on opening that is sleeved over the hub of the gear-wheel, which hub together with the end. of the crank is held in position upon the stud b by e split-key 'y, as best shown in Fig. 1.
By the foregoing description it will be seen that ail of the parts may be manufactured and assembled with the least possible 1112iohine work, while at the some time provision is made for adjustments, and replacingthe several parts as they become worn, thus nodncing a. machine having all the desired speed and accuracy obtehmble in the class of grinder and polisher to which the invention pertains, st 3, ininirnuzn cost of manufacture.
I claim:
1. In a grinding-machine, having e base COIHPL'lSlIW a "VQItlCELl web, rearwsrdly projecting lateral feet, and t depending clamp ing-leg extension; the combination of e verticnlly disposed bracket in pivotal connection with the vertical web of the base, the bracket being provided with slot eircnmferentially disposed with relation to its pivot, a. clamping-screw fitted into the slot and connected to the base- ,veb, front and rear arms extending from the bracket provided with bee-rings at their ends, a she t mounted in the erins, an obrodingwheei secured to the shaft, a stud projeetin from said base, and e driving gear-wheel mounted upon the stud in gearconnection with the sbreding-wh eel arbor.
, 2. A grinding ineehine comprising a bracket having front and rear ernis terminating in bearings, an ebrztding wheel shaft :rnounted. in the bearings, 21- cirennlferentiaily adjustable piste fitted over one of said beerings, and e, radially adjustable tool-rest cerried by the piste. Y
in testimony that 1 claim the foregoing i have hereunto set my hand at Milwaukee in the county oi hitilvmul ee and State of Wisconsin in. the presenceoiv two witnesses.
