KEYING CONNECTION FOR DENTAL BRUSHES.
Specification of Letters Patent.
Patented Jan. 6, 1914i.
Application filed May 3, 1912. Serial No. 694,976.
To all whom it may concern Be it known that I, PETER N. SoUZoN, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improvement in Keying Connections for Dental Brushes, of which the following is a specification.
It is well known that a dental brush cannot be used more than once in order to insure cleanliness and prevention of contracting diseases, and my object is to employ a novel construction of brush spindle and removable brush and its adjuncts, so that the dentist or operator can easily replace a new brush on its spindle so that the same spindle can be continuously used, thus reducing the cost of the use of the instrument to a minimum, since the brush proper being readily detachable, the spindle will be allowed to remain in the tool holder of the dental engine, while the used brush can be taken oil the spindle and a new one replaced, as occasion requires.
For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.
Figure 1 represents a side elevation of the brush spindle. Fig. 2 represents a portion of the brush member in detached position. Fig. 3 represents an end view of the brush in assembled position. Fig. 4: represents a side view of the brush and spindle in assembled position.
Similar numerals of reference indicate corresponding parts in the figures.
Referring to the drawings :The brush spindle is provided with a suitable shoulder and a key groove 1, the extremity of the spindle carrying the key groove being slightly tapered. The brush proper is provided with an annular, detachable member, which latter is provided with a core and a key indent-ation 2, which is adapted to engage the groove 1 when the parts are in assembled position, as will be understood from Figs. 3 and 4:, the key indentation appearing in front elevation, as seen in Fig. 8. The object of the key groove in the spindle and the key indentation in the core is to enable the brush proper, when slipped on the tapered end of the spindle, to be locked on the same and cause it to rotate simultaneously with the rotation of the brush spindle, it being apparent that after the brush has been used, it can be slipped off the spindle, and a new one replaced on the same spindle, without necessitating the removal of the latter from the dental engine.
My present invention is differentiated from the prior art wherein removable mem bers of considerable size are splined or keyed to a great extent permanently upon their shafts and cannot be removed except by the application of considerable force thereto, as by hammering, pounding or the like, since in my present device, it is essential that the brush member be capable of being quickly and instantaneously removed by a slight manual manipulation by the fingers of the operator, so that the replacing of a new brush can be quickly and almost instantaneously accomplished.
It will now be apparent that I have devised a novel and useful construction of a dental brush which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
Having thus described my invention, what I claim as new and desire to secure by Letdentation engaging said groove, said memters Patent, is her being held in place by friction and being m The hereindescribed improvement in denreadily removable by the fingers of the opertal brushes, comprising a spindle having a ator.
