JAMES L. JACKSON, OF NEW YORK, N.'Y.
IMPROVEMENT'IN TABLES FOR EMERY-GRINDERS.
v Specification forming part of Letters Patent No. 122,253, dated December 26, 1871.
to the accompanyingdrawing forming part of this specification.
This invention relates more especially to tables for use in connection with what are known as or may be termed face-grinders?, the grindingfaces of which coincide with the planes of revolution, such grinders being used as a substitute for planers in producing dat surfaces on castiron or other metal. The purpose of the table is to support and hold the work and present it properly to the revolving face of the grinder. The table is composed mainly of a stationary horizontal shears and a carriage traveling thereong The invention consists in a novel construction of such carriage and in novel appliances f1tted thereto to afford convenience for holding different kinds of work and in a novel system of anti-friction rollers for supporting the carriage on the shears, whereby I am enabled to use a carriage having a considerable amount of motion without making it and the shears of great length, and yet employ rollers of large size.
y Figure 1 in the drawing is a plan of a table with my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is longitudinal vertical section of the same. Fig. 4 is a transverse section of the same.
Similar letters of reference indicate corresponding parts in the several figures.
As the invention relates only to the table, I have not shown any more of the grinder than is necessary to illustrate its position with regard to the table, but have simply shown the emerywheel A in Figs. 3 and 4, its face being shown in Fig. 3 and its axial section in Fig. 4. B B indicate the shears, having their upper surface planed to form a level track for the anti-friction rollers O C which support the carriage, and having grooves in the upper parts of their sides for the reception of tongues aa provided on the overhanging edges of the lower frame D of the carriage, which is arranged to run longitudinally on the shears and parallel with the plane of revolution ofthe grinding-wheel. The carriage consists, besides the lower frame D and the rollers C C and their shafts c c, of a horizontal bed, E, and two upright face-plates, F F. The bed E is tted to the frame D with tongues and grooves b b at the ends to slide across the said frame at grooved horizontally, as shown at c e in Figs. 2 I
and 4, at or near their upper edges, for the reception of sliding clamps G G, which have inserted through them a bar, H, which straddles the two plates and which is adjustable in the said clamps to suit their varying distance apart as the plates are adjusted toward or from each other on the bed E. The said clamps are fitted with set-screws h h to secure them' to the faceplates when adjusted thereon. The said bar is also fitted with sliding blocks I I containing upright binding-screws J J. The bed E and faceplates F F have numerous slots in them, like the bed-plates of planing-machines and the faceplates of other machines for the reception of dogs or clamping-bolts by which to secure the work to them. A screw, K, is fitted to bearings on the Vframe D and to a nut, L, secured under the bed E for the purpose of moving the said bed across the said frame. The face-plates are adjustable upon the bed E by hand, and when adjusted may be secured by clamps or dogs` applied through the slots of the bed. y A
The work to be presented to the emery-wheel may, according to its form or character, be secured to the bed E alone, or to either of the faceplates,'or between the latter, or to both the bed or face plates, and with or without the assistance of the binding-screws J J 011 the bar H 5 and the bed, face-plates, and bar H will, by means of their several adjustments, provide for securing almost any kind of work. The feeding of the work to the emery-wheel will be performed by-a movement ofthe whole carriage on the shears B y B, which may be performed by 'a screw or rack and pinion applied to the frame D. The depth of cut is adjusted by the screw K. The axles c c of the rollers C C, having the said rollers firmly secured to them, pass through horizontal slots g g in the sides of the frame D, and are all connected together by coupling-rods N N outside of the said frame. The upper surfaces of these slots between the traveling carriages of machines and the Ways on which they run, the movement of the carriage relatively to the axles of the rollers is much reduced, and with rollers `of a given size and a carriage having a given travel the carriage and bed may be made shorter.
I have used the terms emery-Wheel and .emery-grinder in this specification with reference to the grinding-wheel; but the invention would be applicable if a grinding-Wheel of any other substance than emery were used, and there fore I do not confine myself in carrying out my invention 'to'the use of Wheel's'fmade ofem'ery.
rWhat I claim as my invention, and desire to secure by Letters Patent, is
1. The carriage, composed of the lower frame D running on the shears, the bed E movable transversely on the said frame, and the faceplates F F movable lengthwise on the said bed, the Whole combined substantially as herein described.
2. The combination, with the two face plates and bed E, of `the'clamp-bar H'connected with the face-plates by screw-clamps Gr G, and furnished with sliding blocks I Inan'd clamping-screws J "J,
substantially as and for the purpose herein de-y scribed. v
3. The combination of the shears B, rollers C C, axles c 0,'rodsN N, and slots lgv in the vlovver frame D of the carriage, the Whole arranged substantially as described, A'for the purpose set forth.
