IMPROVEMENT IN DENTAL POLISHING-TOOLS.
Specification forming part of Letters Patent No. 169,753, dated November 9, 1875; application filed July 9, 1875. r
CASE E.
To all whom it may concern:
Be it known that I, SAMUEL S'rooKToN WHITE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Polishing-Tools, of-which the following is a speci fication:
My invention relates to that class of polishing instruments in which a reciprocating movement is imparted to the tool. Its objects are to furnish a direct-acting reciprocating polisher, which shall be simple in construction, efficient in operation, and readily adjustable to vary the length of stroke of the polishingtool; to which ends my invention consists in imparting to the tool a lateral vibratory motion in addition to the ordinary reciprocating motion, thus producing an efiicient rubbing action.
The subject-matter claimed is hereinafter specifically designated.
In the accompanyingdrawings, Figure 1 represents a vertical longitudinal section through my improved polisher; Fig. 2, a similar horizontal section therethrough.
In order to give a wide range of movement to the instrument, I prefer to drive it from any suitable motor by means of a flexible shaft, A, of well-known construction, which drives a crank-shaft, 13, mounted in bearings in a suitable casing or hand-piece, U. The crank 1) drives a pitman, D, the throw of which may be adjusted by means ofa series of holes in the crank-wheel at different distances from the center, or bya slot and set-screw, or other well-known equivalent means. 'A longitudinal slot, cl, is formed in the pitman, through which a pin, 0, passes, and on which pin the pitman rocks as it is reciprocated; consequently the outer end of the pitinan will be vibrated laterally as well reciproca-ted longitudinally, thus imparting to the tool E, inserted in a socket in the pitman, or secured thereto in any well-known way, a compound rubbing motion, which is ery efiicient.
The range of motion of the polisher can be varied by adjusting the crank-pin, and by moving the fulcrum-pin c backward or forward in the casing, which can be done by mounting it in a sliding sleeve actuated by a screw; or a simple slide will answer.
In a polishing-tool, the combination, substantially as hereinbet'ore set forth, of the easing or hand-piece, the crank-shaft, the longitudinally-slotted pitman or tool-holder, and the pin on which the pitman slides and rocks, whereby a compound longitudinal and lateral reciprocation is imparted to the tool.
In testimony whereof I have hereunto subscribed my name.
