DENTAL DEVICE Filed April 5, 1933 Inmo/71H Gowrwcl D. Qwtmd,
@av/Var MAM,
Patent-ed Feb. 6, 1934 UNITED STATES PATENT OFFICE 7 Claims.
The invention relates generally to a dental device and more particularly to a device especially adapted for treating the gums.
An object of the invention is to provide a novel device of this character by which a message or the like may be properly and conveniently applied to the gums to produce and maintain a healthy condition thereof.
Another object is to provide a new and improved device capable of producing and transmitting to the gums through a suitable applicator, such as a tooth brush, a stimulating vibratory massage.
More specifically stated, other objects reside in the provision of a new and improved device of this character in which the massaging motion is reciprocatory and oscillatory, which embodies simple and eflicient means for producing such motion, which includes a novel arrangement whereby the operator or user may start and stop said motion at will, and which may be manufactured and sold at a low cost for distribution to individuals or families for home use.
A further object is to provide an improved tooth brush for use with a device of this character embodying simple means for detachably connecting the brush to the driving means so that the brushes of several individuals may be used with a single driving means.
Other objects and advantages will become apparent in the following description and from the accompanying drawing, in which:
Figure 1 is an elevational View on a reduced scale of a device embodying the features of the invention.
Fig. 2 is a longitudinal section through the device, a part of the section being taken on the axis.
Fig. 3 is a sectional View looking downwardly of the device as shown in Fig. 2, the outer casing only being in section.
Fig. 4 is a bottom view of the left-hand end of the device as seen in Fig. 2 with the outer casing in section.
While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawing and will herein describe in detail the preferred embodiment, but it is to be understood that I do not thereby. intend to limit the invention to the specific form disclosed, but intend to cover all modications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.
Generally the mechanical organization of the (Cl. 12S-62) device embodies a suitable source of power, such as a motor, drivingly connected with a power translating device which is mounted in a handpiece dimensioned for convenient manipulation by the operator. In the present embodiment, the power translating device changes a rotary motion derived from the motor into a combined reciprocatory and oscillatory movement which is transmitted to a-gum treating or massaging implement, such as a tooth brush. The vibratory and oscillatory movements preferably are short, rapid, and relatively sharp so that the brush has what may be considered generally a circular vibratory movement, although the characters of the dilierent strokes are definitely maintained. Suitable means are preferably included in the device for manipulation by the operator in control of the driven movement of the brush. The tooth brush or other implement has a detachable connection with the device as a whole so that a single driving unit may be used by a number of dierent individuals.
Referring particularly to the drawing, in which a preferred form of device embodying the invention is shown merely for illustrative purposes, 10 designates a driving motor which may, if desired. be provided with such means as an eye 11 for supporting the motor in any convenient position. The armature of the motor, through suitable connections generally designated 12, is drivingly con nelted with a flexible power transmitting element or shaft 13 (Fig. 2) housed within a flexible tubular guide 14. The outer end of the flexible shaft 13 is connected with the power translating device which is mounted within a relatively small elongated casing l5, the dimensions of which are such that the device may be easily handled by the user.
The construction and assembly of the power translating device and casing may best be seen in Figs. 2, 3 and 4. Within the casing l5 is a snugly tting tubular barrel 16 which is approximately coextensive with the casing. At one end, the barrel has screw threaded engagement with a guiding element 17 constituting a bearing for the outer end of the exible shaft 13. The end of the ilexible shaft extends beyond the element 17 into the barrel 16 and is there rigidly connected with a driving member 18 journaled in the end of the barrel. The driving member 18 has an annular groove 19 therein engageable by a pin 20 which is rigid with the barrel 16 said pin and groove being for the purpose of securing the driving member 18 against axial movement in the barrel.
The power translating device proper comprises in this instance a cylindrical member formed ci? two sections 21 and 22 dimensioned snugly to nt within the barrel yet movable relative thereto. One of the sections, in this instance the inner section 21, is drivingly connected, as by means of a tongue 23 and slot 24 arrangement, with the driving member 18 whereby the parts rotate conjointly yet may have relative amal movement.
The outer or end section 22 is connected with section 21 for relative rotational. but non-axial movement. A preferred connection comprises a pin 25 rigidly secured, as at 26, to the section 21 and extending axially therefrom into an end recess 27 in the section 22. An enlarged head 28, fitting snugly within the recess 27, is held against axial movement relative to the section 22 by a tubular nut 29`screw threaded into the section 22. Preferably fibrous, anti-noise washers 30 are interposed between the head 28, the base of the recess 27, and the end face of the nut 29.
The rotational movement of the driving member 18 is translated into reciprocatory movement by cam means herein shown as comprising an annular cam groove 31 formed in the section 21 and a cam follower 32 on the barrel, the construction of which will be presently described. When the cam follower 32 is stationary with respect to the barrel 16, it will be apparent that rotation of the section 21 will cause said section to reciprocate and, through the axially rigid connection, produce reciprocation of the section 22 as well.
oscillatory movement is preferably produced in the section 22 by cam means best seen in Figs. 2 and 4. 33 designates an elongated cam slot formed in the section 22 for engagement by a cam follower 34 fixed on the barrel 16. The cam slot 33 extends generally longitudinally of the section 22 but is angular with respect to the axis of said section so that, as the section reciprocates due to the engagement between the cam groove 31 and follower 32, the engagement between the cam slot and follower 34 causes the section 22 to oscillate or rock.
Preferably the cam follower 34 and the pin 20 are mounted on plates 35 tting snugly and detachably in apertures provided in the barrel 16 whereby to facilitate assembly of the device.
The means by which the user may control the operation of the device includes, in the present instance, what may be termed a clutch device acting upon the cam follower 32. With particular reference to Figs. 2 and 3, the cam follower 32 is fixed to an elongated slide 36 which is seated in a narrow recess 37 extending longitudinally of the outer surface of the barrel 16. A slot 38 in the barrel 16 permits engagement between the cam follower 32 and the cam groove 31, said slot being elongated to allow the follower and slide to reciprocate unless the parts are held against movement. Also seated in the elongated recess 37, in end to end relation with the slide 36, is a. control bar 39 having thereon a nger piece 40 which extends outwardly through an elongated aperture 41 in the casing 15 for convenient engagement and manipulation by the user.
The arrangement of parts is such that the control bar 39 may by proper manipulation be moved into engagement with the end of the slide 36 to hold the slide rmly against movement by the engagement between the cam follower 32 and cam groove 31. When the slide is so held, the section 21 will reciprocate. Upon release of the control bar 39, the slide 38 is free and will reciprocate in the slot 37 since the slide and cam follower 32 are of relatively small mass as compared with that intacte oi? the power translating device. Preferably, a noise-absorbing washer 42 of iibre or the like is interposed between the adjacent ends of the control bar 39 and slide 36.
The outer end of the section 22 extends beyond the barrel 16 and casing 15, as shown at 43,
and this end of the section has an axial recessv 44 therein to receive the end 45 of a dental instrument such as the tooth brush 46. Preferably the implement carries a spring clip 47 having a nib 43 thereon engageable in an aperture 49 in the extension 43 for detachably securing the parts together.
The front end of the barrel has a tapering sleeve 50 screw threaded thereon, the outer surface of which is fiush with the casing surface and pleasingly finishes the assembly. A similarly-shaped part 51 is xed about the guiding element 17 at the other end of the casing. The guiding element assembly and sleeve 50 serve to bind the casing therebetween and thus secure the barrel and casing firmly together.
It will be evident from the foregoing that an improved dental device has been provided by which the gums may be properly treated or massaged to produce the desired tough and healthy condition thereof. It is preferred that the brush have a movement which is the resultant of the reciprocatory and oscillatory movements, since the gums are thereby treated with a simulated rotary motion. The device is exceedingly convenient to use and permits a patient, whose gums have a tendency towards such diseases as pyorrhea, to treat himselfregularly at home. The simple mechanism for controlling the operation of the device is advantageous, since the tooth brush may be caused to reciprocate and oscillate only While it is in the mouth. The entire mechanism is efficient in operation, simple and compact in construction, and may be manufactured and sold at a comparatively low cost.
