To all whom it may concern:

Be it known that I, Grocer ADELMO, a subject of the King of Italy, and a resident of Spring Valley, in the county of Bureau and State of Illinois, have invented a new and useful Improvement in Electric Vibrators for Razors and the like, of which the following is a full, clear, and exact deprovide a razor operating device in which the razor clamp may be removed therefrom and the ordinary type of vibrator appliance substituted. 1

A further object of my invention is to provide a device of thetype described in which particular novel means is employed for housing the internal mechanism to assure against unintentional and discordant vibration.

A further object of my invention is to provide a device of the type described in which the'internal mechanism for vibrating the razor clamp is housed in an insulating casing, thereby insulating all of the electrical parts from the hand of the operator, and also providing a heat insulating medium about the internal mechanism.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accom panying drawings, forming part of this application, in which Figure 1 is a front'elevation of an em bodiment of my invention,

Figure 2 is a partial side elevation of the mechanism illustrated in Figure 1,

Figure 3 is a top lan view of the mechanism illustrated in igure 1,

Figure t is a front elevation of a part of the mechanism illumrated in- Fi ure 1', a portion of the casing being remove therefrom, and

Figure 5 is an enlarged sectional view along the'line 5-5 of Figure 4.

In carrying out m invention I make use I of a casing comprising two cooperating parts A and B. These parts are constructed of molded composition, such as bakelite or other Well known compositions, having insulating properties. The casing is narrowed as shown at 1 upon its side walls so as to facilitate the holding of the casing in the hand of the operator in such a manner as to preclude any slipping of the device due to its inherent vibratory properties. The casing is further provided with vents 2 arranged in symmetrical groups, (see F igure 1) through the major walls of the cooperating parts A and'B. The purpose of these vents is to permit air to circulate through theinternal mechanism of the device and prevent overheating of the mechanism. i

The mechanism employed for imparting vibratory motion to the razor clamping mechanism consists in a substantially Ushaped laminated core having protrusions 4 at each end of the rearward part or heel of the core, (see Figure 4). These protrusions 4 form an ingenious means for preventing unintentional movement of the core 3 relative to the casing. This guard against movement of the core is brought about by the provision of a recess R in the adjacent side Walls of the parts A and B having the shape ofthe rearward portion of the core 3, including cavities C for receiving protrusions 4. In this manner, the core 3 is securely clamped against movement when the parts A and B are secured together as by means of binding screws 5, provided for that purpose.

' Each of the branches 6 and 7 of the core 3 has wound thereupon a coil of current conducting Wire 8. These coils 8 are connected in series with one another at 9, and one of the leads 10 therefrom is connected directly with a conductor 11, the other end of which is connected with a suitable attachment plug, (not shown). This attachment plug is ofthe ordinary type, such as used for stand lamps, flat irons, and the like. The opposite lead 12 of the coils 8 is connected to one terminal post 13 of the switch 14. The opposite terminal post 15 of the swltch is connected to the remaining connection wire 16 wl1ich is in turn connected with the aforesaid attachment plug.

The connecting wires 11 and 16 are both run through a flexible lead 17 formed of a coil of tightly wound spring wire, which 1s projected through registering channels 18 in the parts A and B, at the lower end thereof. The inner end of the spring lead member 1'? is enlarged somewhat to prevent its movementexteriorly of the casing.

The arn'iature upon which the razor supporting clamp is supported is compri ed in a band of magnetizable metal 19 having one end thereof projected through registering channels ot' the parts A and B, and is substantially angular in cross section. The armature 19 is arranged to lie directly in front of the branches 6 and 7 of the core 3, but not normally touching these branches. The lower end of the armature 19 is bent and is arranged to lie directly upon the innermost side of the lower wall of the parts A and P) as shown at :22. A binding plate is disposed upon the outer side of the lower wall of the parts A and B in registration with the part of the armature 19. and machine screws 2 are projected through the plate 2 the lower walls of the parts A and l3, and are threaded directly into the portion 22 of the armature 19. This particular means for mounting the armature 19 is one which I deem oi. particular importance. since it provides a rigid su portt'or the lower most end of the armature, which is an armato re vibrating at an exceedingly high period. and also serves to eli ectively clamp the lowermost portions of the parts A and B against movement apart from one another, thereby doubly assuring the separation of. the casing at this point. which might occur if some such means as justdescribed were not devised.

It is well to note at this time that my improved razor operating device is intended for use upon the ordinary alternating current service line. in wl h the frequency of alternations is oidinarily fixed at 60 cycles per second. It will therefore be apparent that the period of vibration of the armature is most exceedingly nigh, and that rigidity in mounting the internal parts is of utmost importance, particularly in a device of this type.

The switch 14 is more clearly shown in Figure and the internal working parts of the device are mounted upon the disc 14-. Th s disc 14 is arranged to be partially re ce ed within an enclosure formed by the Provision of an inwardly extending annular rl nge 25 on the innermost wall of the part An opening 26 is provided through the Wall of the part A in registration with the a. :is of the annular tlange 25 to permit the projection of the stem 27 of the switch mechanism mounted upon the disc 14. The outermost end of the stem 27 has a knob 28 thereupon. the switch being disposed exte- -e'iorly of th :asing. and may be manually operated by the tu :lng of the knob so as to rotate the commi ator 29, forming a part of the aforementioned switch mechanism.

My improved electric vibrator is primarily intended for operating a razor for shaving, yet the device may be used with equal ad vantage for the operation of any one of the many well known vibrator appliances, such as cups, balls, combs and the like, for the purpose of facial and scalp massage. The following is a description of one form of razor holding device which, while shown in this application, claimed in my copending application Serial No. 744,298.

The razor holding clamp which is arranged for disposition upon the angular portion 21 ot' the armature 19 consists in a body member 90 having an angular loop-shaped member 31. at one end thereot which is arranged to fit over the angular part 21 of the arn'iature. A. thumb screw 32 projected through the body member 30 adjacent to the loop portion 31. provides means by which the loop 31 may be slightly contracted, and in this manner securely clamps the body member 30 upon the arn'iature 19.

The body member 30 is provided with :1 depending member arranged to yieldably engage with the handle 33 of the ordinary type of razor This depending member consists in a pair of spring clamps carried by the body member 30 and disposed at a slight angle with respect to the axis of the part 21 ot the vibrator 19. A separator 36 is disposed between the spring clamping meu'ibers 35 and is arranged to extend slightly below the lowermost ends of these members. Toe lmvermost ends of the members are dished outwardly as shown at 37, so that the split handle 33 may easily be moved beyond the lowermost ends of the spring clamping members 35 when placed astride the separator 36 in the manner shown in Figure 2. The clamping members func tion solely to yieldably hold the handle 33 of the razor against both longitudinal and lateral movement relative to thebody member 30 of the clamping mechanism.

Means for supporting the blade 38 ot the razor 3-4; when first inserted in a suitable guard 39 is provided as follows: A strap -10 is hingedly mounted at all to the body member 30 in such a manner as to permit the strap 40 to be moved to the position shown in full lines in Figure 1, or to the position shown in dotted lines. In both cases the strap 4-0 lies in a plane substantially parallel with the separator 36.

This strap 4-0 has disposed at its outermost end a spring pressed clamp 42, the worl: engaging part 43 of which is in turn pivotally connected to the clamping member 4-2 so as to completely conform ith the irregular configuration of the neck of the razor 34. It is therefore evident that the razor blade 38, together with its guard 39 may be firmly secured against movement upon the body member of the clamping various parts of the device, the operation thereof may be readily understood. The person using the device will first manually place the guard 39 between the strap 40 and the spring pressed clamping member 42 so that the blade 39 is securely fixed against movement relative to the strap, and therefore to the body member 30.

The strap 40 is then hinged to the position shown in full lines shown in Figure 1 or to the position shown in dotted lines, de-

ending upon which side of the face is to lie shaved, and the blade 30 is hinged upwardly so that the split portion thereof may lie astride the separator 36 and be received between the spring pressed clamping members 35 which will securely hold the handle against movement both longitudinally and laterally. The switch mechanism operated by the knob 28 is then closed so as to permit current to flow through the coils 8, thereby causing a magnetic field about the branches 6 and 7 of the core 3, and consequently causing the exceedingly high vibratory movement, which movement in turn will be imparted to the blade 38 and move the blade laterally. The blade is then moved over the face in precisely the same manner as though the razor operating device were not employed, except that a swift stroke of the razor is not necessary.

Obviously my improved vibrating mechanism may be used for the purpose of supporting a suitable clamping device upon the stem 21 for holding ordinary types of safety razor, mechanical vibratory appliance or the like, without in any way departing from the spirit and scope of the invention.
