7 Claims.

My invention has reference to electro-therapeutic and mechanical vibratory devices for imparting beneficial treatments to the human body.

It is a purpose of my invention to provide a portable device by which the human body can be simultaneously massaged, and treated with heat and infra-red or other forms of health giving rays, and wherein the source of heat and light rays are likewise vibrated.

Another purpose of my invention is the provision of. a device of the above described character which embodies a vibrator and various forms of applicators for treating various parts of the human body and any one of which contains an electrical element for producing health giving light rays and heat, and is readily attachable to the vibrator to be vibrated thereby so that it functions when applied to the body to massage the latter concurrently with the application of light and heat.

It is also a purpose of my invention to provide a device in which the vibrator part thereof is of extremely simplified and durable construction, and which embodies an electromagnet as the vibrating means, the armature thereof being controllable by mechanical means adjustable to vary the amplitude of its vibrations and in consequence the vibratory motion of the particular applicator attached to the vibrator.

I will describe only one form of electro-therapeutic and mechanical vibratory device and three forms of applicators, all embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 10 is a view similar to Figure 9 showing another form of applicator embodying my invention, but with parts of the vibrator and applicator in elevation.

Figure 11 is a diagrammatic view showing the electrical circuits for the device and a current supply means for the device.

Similar reference characters refer to similar parts in each of the several views.

In carrying out my invention, I provide a two part casing of insulating material, one part K constituting a frame for supporting certain elements of the device, and the other part K constituting a cover to conceal the elements mounted on the frame. The frame K is structurally characterized by a ring shaped head 15 at one end of the frame which provides an opening in the front side of the casing, and in this opening a vibrating head 16 is adapted to be moved by means of the armature 17 of an electro-magnet. The magnet comprises, in the present instance, a winding 18 and a three pole laminated core 19 secured on the inside of the frame K.

The armature 17 is poised within the influence of the core 19 by a U-shaped spring 20 secured at one end to the inside of the frame K between a plate 21 and. the frame by screws 22. At the other end the spring is riveted to the armature 17, and thus the armature is resiliently supported so as to be capable of vibration by and when the magnet is energized with alternating current.

The amplitude of the vibrations of the armature 17 can be varied within a certain range by the provision of a short spring 23 riveted to the armature and engaged by the inner end of a screw 24. This screw 24 is threaded in the bore of a stud 25, and the latter is threaded in the plate'21, as best illustrated in Figure 6. The outer or head end of the screw 24 is disposed in a pocket 26 of the head of the stud 25 and so as to be accessible from the outer side of the casing to permit rotation of the screw in the stud for effecting longitudinal adjustment thereof to increase or decrease the pressure exerted thereby on the spring 23. In this manner vibratory movement of the armature 17 can be varied at will.

As best illustrated in Figure 5 the armature 1'7 operates at one end between partitions 27 extending inwardly from the cover K, and these partitions abut the winding 18 of the magnet to hold the winding and core in fixed position within the casing. Plates 28 of insulating material are interposed between the winding and the sides of the frame K also to secure the winding against displacement from the frame.

The opposite end of the armature is connected to the vibrating head 16 by threaded studs 29 secured in bosses 30 on the inside of the head, and the studs are provided with nuts 31 for securing the armature to the studs. The armature extends diametrically of the vibrating head and is seated in recesses 32 in the edge of the vibrating head, so that by means of the studs and nuts the armature is fixedly secured within the recesses to prevent relative movement of the armature and vibrating head, it being understood that it is essential to the proper vibration of the head that the armature be fixedly secured thereto.

The vibrating head is of such length as to project from the ring head 15, as best, illustrated in Figure 6, and as here shown it is interiorly screw threaded as indicated at 33 for the reception of various forms of applicators, each containing an electrical heating and lighting element. As will be more fully described herieinafter, current is adapted to be supplied to the electrical element of each applicator through the vibrator, and hence it is necessary that suitable electrical connections be provided between the vibrating head and each applicator. To this end I provide spring contacts 34 and 35, one extending longitudinally of the head and the other transversely thereof, as best illustrated in Figure 9. By means of screws 36 these contacts are secured to internal bosses 37 of the head.

In Figures 6 and '7 I have shown one form of applicator embodying my invention in applied position to the vibrator, and this applicator is particularly designed for the vibratory massaging accompanied by the application of heat and light rays to exterior parts of the human body, and particularly for massaging and melting cosmetic creams into the facial tissues at the same time efiecting a valuable tissue stimulating light, heat, and massage treatment.

The afore-mentioned applicator comprises a cylindrical body 38 of insulating material having a reduced end 39 which is exteriorly threaded for engagement with the internal threads 33 of the vibrating head. Within this reduced end is a disk 40 constituting an integral part of the body 38 and formed centrally with an opening in which is secured a contact plug. As best shown in Figure 7, this plug comprises an external tube 41 formed of conducting material. One end of this tube has a driving fit within the opening of the disk 40 so as to provide a water tight joint between the two. Within the tube 41 is a second tube 42 formed of insulating material and projecting from the inner end of a tube where it is provided with an annular collar 43. A third and shorter tube 44 formed of conducting material extends into the tube 42, and where it projects from the tube 42 it is likewise provided with an annular collar 45.

One wire 46 is connected to the collar 45 and extends through the tubes 42 and 44 and into the interior of the body 38, as shown in Figure '7. A second wire 47 is connected to an off-set part of the outer tube 41 by means of a screw 48, and this wire extends through an opening 49 in the disk 40 so as to likewise be disposed interiorly of the body 38.

These wires 46 and 47 constitute the terminals of an electrical element 50 which when energized provides a source of heat and a source of health giving rays. This element 50 comprises a coil of chromium alloy wire or any other material which when heated emits a generous amount of infra-red rays. As shown in Figure 8, the element 50 is secured in circular form on one side of a disk 51 by a circular arrangement of headed pins 52, while the ends of the coil are extended through slots 53 in the disk and to the opposite side of the latter where they are connected to the respective wires 46 and 47.

The disk 51 is formed of insulated material and is secured by a driving fit in the body 38 and against an annular shoulder 54. Covering the element 50 is a concavo-convex lens 55 which is grooved to receive the edge of the body 38, as shown in Figure 6, and in such manner that the lens is secured against displacement from the body. This lens constitutes a massage member and it is constructed of crystal, quartz, or any other material which has the property of transmitting infra-red rays therethrough. By constructing the lens as described, it serves to concentrate the light and infra-red rays passing therethrough as emitted from the element 50 so that in operation the part of the body to which the lens is applied can be treated by heat and light rays and at the same time massaged.

In applying the aforedescribed applicator to the vibrator, the body 38 is screwed into the vibrating head 16, and in so doing the plug of the applicator is moved into engagement with the spring contacts 34 and 35 so that the latter engage, respectively, the contact tube 41 and the contact tube 44 for supplying current to the element 50, assuming of course, that the sprin contacts are connected to a source of current. With the plug inserted as shown in Figure 7, the contact 44 engages the side of the plug, while the contact 35 engages the end of the plug, and by reason of the construction of the spring contacts, the plug serves to hold the contacts under tension. The tension thus produced reacts to retain the plug against rotation and with sufficient security to prevent accidental unthreading of the applicator from the vibrating head. This is an important feature of my invention for it is essential that the applicator be fixedly secured in the vibrating head to prevent loosening and subsequent displacement thereof under the vibrating action of the head.

Referring now to Figure 9 I have here shown another form of applicator embodying my invention and adapted for use in connection with the vibrator. This applicator is in the form of a dilator for administering rectal and vagina treatments, and as in the other applicator it is useable to simultaneously massage, heat, and treat with light the affected part.

The dilator comprises a hollow body 56 which is formed of any suitable insulating material and provided at one end with an exteriorly threaded and flanged collar 57 which is adapted to be threaded into the head 16 of the vibrator. The collar 57 is completely closed by a disk 58 of insulating material, and this disk carries a contact plug 59 of the same construction as the between the contacts and the plug for supplying current to the lighting and heating element of the dilaton. Also, the spring contacts being placed under tension to prevent ancidental unscrewing of the collar from the head. The insulating tube 42 of the plug is extended beyond the inner end of the outer tube 41 for the purpose of receiving and supporting a tube within the dilator body. This tube 60 contains the electrical element 61 which is likewise in the form of a coil of chromium alloy wire for the purpose of emitting infra-red rays, and as shown in Figure 9 one terminal of the coil is connected to the conducting tube 44 while the other end is extended from the free end of the tube 60 and along its outer side where it is finally connected to the outer conducting tube 41.

The tube 60'is formed of glassor any other material having refractory properties to increase emission of infra-red rays from the element 61, and to thereby increase the therapeutical effect of the rays in the adaptation of the dilator to the various parts of the body. The association of the disk 58 with the collar 57 and the plug 59 with the disk 58 is such that the entire body of the dilator is hermetically sealed against the entrance of fluid, and as a consequence the dilator can be immersed in a sterilizing solution without damage to any of its parts.

In the adaptation of the dilator to the vibrator, the element 61 is heated to emit heat as well as infra-red rays, and the dilator is simultaneously vibrated thus permitting the administration of a massaging action as well as heat and light to the part being treated.

Referring now to Figure 10 I have here shown a third form of applicator embodying my invention. This applicator is particularly adapted for treating the gums of the teeth for the purpose of stimulating circulation in the gums to promote healthy tooth growth and alleviate pyorretic conclitions.

The gum treating applicator comprises a tubular body 62 formed of insulating material and terminating at one end in a collar 63 of the same construction as the collar 57 of the dilator and having a contact plug adapted for association with the spring contacts for supplying current to the electrical element of the applicator. As in the instance of the dilator, the body 60 contains an electrical heating element 64 enclosed in a glass tube 65. However, the element 64 is relatively short and co-extensive in length with an opening 66 in one side of the body 62, and which opening is closed by a lens 67.

In the use of this applicator, the lens constitutes a massage member and permits radiation of heat and theinfra-red rays so that the tube can be simultaneously applied to the gums during the massaging operation, it being understood that the applicator as a whole is vibrated when in operation.

In Figure 11, I have shown diagrammatically the necessary circuits for supplying current to energize the electromagnet for effecting operation of the vibrator, and heating of the electrical element for producing the heat and light rays. The circuits are associated with the form of applicator illustrated in Figure 6, although it will be understood that the same circuits can be employed in connection with the other two applicators for heating their respective elements.

In Figure 11 is also shown a cabinet 68 which contains electrical devices for connecting and controlling the supply of current 'to my device,

although it will be understood that other forms of devices'than those shown can be employed.

In Figure 11, alternating current supply lines 69 and '70 are adapted to be connected to cabinet contacts '71 and '72, and from'these contacts wires '73, '74, and '75, lead to contacts 76, '7'7 and '78, the

wires '74, and '75, being in parallel. In the wire '75 is interposed a resistance coil 79, and also a rheostat 80. Wires 81, 82, and 83 are adapted to be connected to the contacts '76, 7'7, and '78, respectively, the wires 81 and 83 being connected to the terminals of the heating and li hting element 50 so that the latter is in series with the rheostat and the coil 79. Thus the coil '79 serves to reduce the current supplied to the element 50 for preventing excessive heating thereof, while the rheostat 80 permits regulation in heating of the element to suit the requisites of a particu ar applicator or treatment.

The magnet winding 18 is adapted to be connected in parallel with the element 50 by wires 82 and 84 and a switch whose arm 85 is pivoted on a bar 86 (Figure 3) of conducting material to engage and disengage a contact 87 in series with the wire 81. Thus the magnet can be energized by closing the switch to efiect operation of the vibrator.

Although I have herein shown and described only one form of electro-therapeutic and mechanical vibratory device and three forms of applicators all embodying my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.
