Description
Patented Dec. 10, 1929 UNITED sra we we nnnc'rn'ro meme eace Application and March 1a, 1925} pram-m My invention relates to electric vibratory if the "magnetic "resistancelbetween the tongue devices, particularly electric safety razor and" massage devices. y V
An important object of the invention is to 5 provide a structure in which the support for a tool, such as a razor blade or massage ele ment, is entirely free from direct mechanical movement or-impact engagen'ient by an armature, but to which vibration is transmitted reactively by a freely vibrating armature whose vibration cannot be interrupted by abnormal use of the tool, such as excess pressure.
Another object is to producea simple and compact structure which can be economically manufactured and which is electrically shock proof and whose internal operating parts are protected from dirt and moisture.
The above and other features of construction and operation are embodied in the structure shown on the drawing in which:
Fig. 1 is a plan view with the grip shell in vertical section;
Fig. 2 is a side elevation with the supportheads and grip shell in vertical section;
Fig. 3 is a section on plane 3-3 Fig; 2;
Fig. 4 is a section on plane 4- -4Fig. 2, and
Fig. 5 is a plan view of the front end of the device with the front head in section, and
showing a modified form of toolsupporting 0st. 1 I
The structure comprises front and rear heads 10 and 11 of insulating material, be-
tween which heads extends the electromagnet 5 core 12 which threads into the front head and is secured to the rearhead by a screw 13.
Insulating washers 14'and 15 confinethe energizing winding 16 on the core.. J p
Above-the core a spring 17. is secured to the rear head, preferably by being molded thereg in, and this spring extends a distance forwardly and terminates in a sleeve 18 for receiving and securing the rear end of. the 4 armature bar 19.
is curved longitudinally, as shown, to decrease Nearjits rear end t are arma I ner. The adjustment securely anchored .at-"its inner yend qmolded into the head. Theouterien post is threaded to receivesuitable tools I. In 5 1 Fig. lit receives the socke't'iBO;ontlej'frame 9 This bar extends forwardly above the core and at itsifront endhas the tongue 20 extending downwardly past and at emcs a ef nr aom and thef eylindrical 'ole end I tilrebarihas the contact point 21 for cooperatingwith the 00m tact spring 22 whosebase 23] is deflected and seats in the channel 24 in the head 11, and is there secured by. a nut-25 on the innerjend' of the terminal pin 26 which is-ernbedded in the head andextendsa distance rearwardly thereof. A companion terminal pin 27 is embedded in theliead 11 and projectstherefrom-adja cent to "the pin 26, these pins receiving asuitable supply circuit terminal socket" (not shown). y y
The pin 27 is defiectedradially to extend 05 within the channel 28 atthe inner end of the head 11, the inner end of the in being defloated forwardly to have sol cred thereto one terminal of the energizing winding '16 whose other terminal connects with the arma ture contact 21. .This:c'ontact and spring 22 form the circuit make'and break mechanism when a direct current circuit is connected to the terminal ins, and the armature bar will be rapidly vi rated in the well known manof the armature sup-.1 r porting spring 17 and the make and -break mechanism is suchthat the armature tongue 20 will not strike the core poleiendihutwill for s'upportin'g'a safety 'razo :b evident that massaging or. o

the ends of the terminal. 1pmsf26 and washer .36 is 'preferably nsferted be 9- tween the shell end and the head 11 to seal the shell against the entrance of moisture or dirt.
In the modified arrangement shown in Fig.
5 the tool supporting post extends from the pocket 37 and comprises the base 38 and the body 39 between which is a flexible section or spring 40 which may be integral with the base and body. The base has the threaded stud 11 which may detachably engage in a threaded opening in the head or may be securely molded therein. The threaded lug 42 on the body 39 serves to receive the tools to be operated.
The spring 40 makes the tool supporting post resilient and yieldable and smooths out and more or less softens the vibrations of the too When a shaving tool is applied the vibrations of the armature are reactively transmitted to the head 10 and through the post to the shaving tool, and the blade is vibrated or oscillated longitudinally so that its edge will cut the hair and not pull it. At the same time a soothing massage is given. The blade could be omitted and the frame 31 could be used as the massaging tool, or special massaging cups or other devices could be applied to the post. As the, armature vibrates entirely freely and without impact, the reactive vibrations will cause operation of the tool which is smoother and more desirable than where the tool is mechanically driven or subjected to vibration impact as is the case in prior devices of this class. Such freedom from direct mechan: ical cooperation between the armature and tool also makes it impossible to stop or interfere with the vibratory movements of the armature by abnormal use of the tool, such as excessive pressure.
Where the tool supporting post is resilient, as by the interposition of a spring 40, the operation of the tools will be more elastic and softened without detracting from the power of the vibration.
As the entire enclosing or grip structure is of insulating material and as the tool supporting post is entirely insulated by the head 10 from all metallic operating parts, there is no possibility of the user receiving shocks. The structure is also entirely sealed and protected against the entrance of dirt or moisture.
Having described my invention, I claim as follows 1. In a device of the class described, the combination of a front head and a rear head, an electromagnet core extending between said heads and having an energizing winding, an armature parallel with said core, a spring extending from the rear head and secured to the rear end of the armature to support it for vibration, the front end of'the armature being deflected to extend alongside of the adjacent core pole end, and a tool supporting post secured on and extending from said front head independently of said armature.
