-MASSAGING Application filed August 14, 1924. Serial No. 732,037.

lily invention relates to a massaging-machine for treating-nervous diseases and simila: ailments. I w

An object of the invention is to provide a machine having an electrically heated Inassaging. element, mechanically operated to facilitate the rubbing of'various parts of'the body whereby the nervous system can be treated.

A further object of the invention is 'to provide a device of this character which is simple and durable in construction, reliable and efiicient in use, andinexpensivetomafiufacture.

Gther objects and advantagesof'the invention willbe apparentduring'the course of the following description.

In the accompanying drawings, formihg'a part of this specification and in which like numerals are employed to designate like parts'lthroug'hout the same,

Fig. '1, is a top plan view of the machine,

Fig. 2 is aside elevation of the same,

Fig. 3, is abottomplan view with thebase removed,

Fig. 4, is a front end view r the same,

Fig. 5, is'a rear'end viewof the-same,

Fig. 6, is a fragmentary cross sectional view skewing the lectrical connections,

Fig. 7, isa horizontal cross section of the massaging element, and, r

Fig. 8, is a fragmentary side elevation of the electrical connections.

In the drawings, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the numeral 5 denotes the main frame composed of complementary upper and lower sections 6 and 7 clamped together by bolts 8, the lower section 7 being mounted on the base board 9 and secured thereto, at its sides and ends, by bolts 10. The frame is relatively narrow and each section has a semi-circular recess on one end, providing a seat for the electric motor 11 which is clamped between the sections extending beyond the sides thereof. At the opposite end of the frame are a pair of longitudinally extending arms 12 disposed in spaced superimposed relation. The arms have concaved grooves 13 on their inner sides in which the U-shaped frame 14 is slidably mounted. The frame 14 is formed from a pair of L- shaped members 15 and 16 joined together by lugs and bolts 17. To impart a reciprocating motion to the U-shaped frame 14 a pair of cranks 18 at one end are connected to the center of the frame on opposite sitles'thereof, as at 18, the cranks being bowed outwardlg and eccentrically connected at their opposite ends to the disks 19, as at 19", mounted on the ends of the Shawnee of the motor '11.

A flat massaging element '21is clamped at its center jalong "its longitudinal edges between the flanges 29 formed integral with the sides of the U-shaped frame lit, by bolts The massaging element extends beyond the end of the frame and consists of a core 24 having a coil of "wire '24":at each end, the whole being completely enclosed by the cas- 'ing 25. The wires connecting *the coils and leading to and from'theinassaglng'eleinent pass along :the central longitudinal grooves 26 extending the length of'the sides ofthe u shaped frame. The wires from the massaging element arerespectively connected with the terminals 2 7niounted on opposite sides ofthe frame at its lowecrear corneiz. Each terminal carries a brush 28 having sliding contact with the contact strips 29 mounted on the insulating blocks 30;seat-ed in the arm 1-2of the lower section 7 of the frame near the motor. Oneof'thecon-tact strips ais con nected with the terminal 31 and the other with the terminal 32 mounted in a recess 82 in the lew'er section 7. A terminal 33 is mounted adjacent the terminal 32 and wires 34 and 34 lead. from each of the terminals 31 and 32 to the motor. A cable 35 has connection with the terminals and 33 and passes through an opening 35 in'the section 7 having its free end equipped with a plug 36 adapted to be connected with a source of current to run the motor and heat the wire coils of the massaging element.

In use, the fingers of the hand are folded against the palm as illustrated in Fig. 3, and the nails of the fingers placed against the sides of the massaging element. The motor is then started causing the massaging element to reciprocate, rubbing the nails vigorously and at the same time permitting the heat waves from the massaging element to pass through the nervous system of the body. This treatment will stimulate the nerves and will produce effective results in the treatment of nervous diseases.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1 claim:

1. A machine of the character described comprising a frame composed of separable sections having longitudinally extending arms disposed in spaced superimposed relation, a U-shaped frame slidably mounted between said arms, a massaging element clamped within said U-shaped frame, heating coils carried by said massaging element, a motor mounted within said first mentioned frame, cranks connecting the motor with said U-shaped frame and a source of energy connected with said motor and heating coils.

2. A machine of the character described comprising a frame composed of upper and lower sections, a motor clamped between said sections, a Ushaped frame slidably mounted between said sections, a massaging element mounted within said U-shaped frame, heat-- ing coils carried by said massaging element, means connecting said motor with said massaging element adapted to reciprocate the latter and a source of energy connected with said motor and heating coils.

3. A machine of the character described comprising a frame having longitudinally extending spaced arms, a U-shaped frame slidably mounted between said arms, a massaging element clamped within said U- shaped frame, heating coils carried by said massaging element, stationary contacts mounted on said lower arm, a source of energy connected with said stationary contacts, contacts attached to said U-shaped frame having connection with said heating coils, adapted to slidably engage said stationary contacts and means for reciprocating said U-shaped frame.

4. A machine of the character described comprising a main frame, a lJ-shaped frame slidably mounted in said main frame, a massaging element clamped within said U- shaped frame, heating coils carried by said massaging element, a motor mounted in said main frame adapted to reciprocate said U- shaped frame, stationary contacts carried by said main frame, a source of energy connected with said motor and stationary contacts, and movable contacts carried by said U- shaped frame having connection with said heating coils, adapted to engage said stationary contacts.

A machine of the character described comprising a main frame, a U-shaped frame slidably mounted in said main frame, a massaging element clamped within said U- shaped frame, a motor mounted in sa'd main frame, cranks connecting said motor with said U-shaped frame, and a source of energy connected with said motor.

6. A machine of the character described comprising a main frame composed of upper and lower sections, a motor clamped between said sections, a Ushaped frame slidably mounted between said sections, a massaging element clamped within said U-shapcd frame, cranks connecting said motor with said ii-shaped frame adapted to reciprocate the latter, and a source of energy connected with said motor.
