that@ tetta THOMAS HARDING, or LA rAYnrrnfiND'IANA Letters Patent No. 111,057, dated January 17, 1871.
IMPROVEMENT lN EMERY-WHELS.
The Schedule referred to in these 'Letters Patent and making part of the same.
' To all whom it may cm1-cern.-A
Be it known that I, THOMAS HARDING, of La Fayette, in the county of Tippecanoe and State of Indiana, have invented a new and nsefulImprovement in Polishingand Grinding-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the` accompanying drawing, in which- Figure l is a side elevation of my wheel.
Figure 2 is a cross-section on line x x of fig. l.
Figures 3 and 4 'exhibit modifications in the con-4 struction ofthe same.
My invent-ion relates to` elastic wheels used for grinding and polishing metals; 'and l It consists in adjustable elastic supports placed between a rigid hub and a slightly exible vrim to hold the grinding or polishing material, and also in a method of constructing said rirn to adapt it to supports not placed in near contact with each other.
I am awarethat.polishing-wlieels have been heretofore made with elastic surfaces, the elasticity being produced by the usc ot" bands of In'dia rubber, felt, sea-horse hide, 86e., and by dividingr therim of the wheel into radial segment-s, with a coiled spring beneath each segment.
My wheel is unlike either of these, which are subject to the following objections First, elastic rubber bands are not durable, and, at considerable expense, they require frequent renewal.
Second, the bands of felt, sea-horse hide, Snc., cannot be joined without imparting a different degree ot' elasticity' at the point of fastening. Third, the radial segments impart a' constantly varying degree of elasticity.
That others may vfully. understand my invention, I will particularly describe it.
The wheel A is constructed of metal, with a'proper hub to' receive a mandrel.
The periphery of the wheel A is pierced with cham bers B, to receive the plungers C, which supportthe grindingrim D. j
Each plunger C is provided with a flange-head, d, and a screw-bolt, e, which extends through an orifice in the bottom of the chamber B, and is provided with a screw-nut, f, to prevent it from withdrawing therefrom.
Within the chamber B and beneath the` plunger C, I place a spring, E, either of coiled wire or gum, which is more or less compressed by the action of the bolt e and f, and therefore aiords a ready means of adjusting and regulating the position of the flangehead d, and thereby adjust the balance of the rim D.
The rim D iscomposed of successive layers of leather orother suitable material, glued, cemented, or otherwise fastened together, until the required thickness is obtained.
The iian'ges d are 'secured to the inner surface ot l this rim by screws or other devices,-and the nuts f being then relaxed, the rim is distended by the actionport to another taking place in a perfectly graduated and uniform manner.` p I Theperiphery of the rim D is made truly concentric to the axis of the hub of the wheel A, by greater or lesser compression of the springs E, as may be required.
In tig. 3 is represented a modified construction, consisting in the employment of an elliptic spring, instead of coiled spring, and dispensing with the chambers B.
lnjig. 4 the required tension and elasticity are secured by means ofthe tubular spring S, laid between the rim D and wheel or hub A, and compressed by means of a screw stirrup, T.
Having described my invention, i What I claim as new is- 1. A polishing-wheel, constructed with a slightlylexible rim, connected to a 'rigid hub, by means of' elastic -supports made adjustable, so as to center or balance said rim, substantially as set forth. 4
2. The chamber-cd wheel A, in combination with the plungers C, screw-bolts e, and elastic springs E, constructed substantiallyas described, to support the rim D, as set forth. A 3. The 4rim D, constructed of successive layers of leather or othersuitable material, glued., cemented, or otherwise fastened together, in combination with elastic supports C, resting upon a rigid wheel, as and for the purpose set forth. v
THOMAS HARDING.
