UNITED STATES PATENT OFFICE.
BENJAMIN RUSH DAVENPORT, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ELECTRIC COUCI-I COMPANY, A CORPORATION OF DELAWARE.
ELECTRICAL MEDICAL APPLIANCE.
T all whom "it may concern:
Be it known that I, BENJAMIN RUSH DAVENPORT, a c1t1zen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electrical Medical Appliances, of which the following is a specification.
The object of this invention is to provide an electr1cal medical appliance whereby a portion of the body of a person may be subjected to an electric current intermittently, and whereby difi'erent portions of the body of a person may be subjected to an electric current intermittently, and in prescribed order, and whereby the intensity of the electric current may be regulated.
To this end the invention consists in the novel construction and combinations of parts which will be hereinafter fully described and claimed.
In the drawings :-Figure 1 is a plan view of my improved electrical medical appliance. Fig. 3 is a plan view with the cover removed. Fig. t is a vertical section, as on the line 1 of Fig. 1. Fig. 5 is an elevation of the rotatable disk carrying the brushes. Fig. 6 is an elevation of the commutator. Fig. 7 is a detail, in section, of one of the contact devices. Fig. 8 is a detail in section of one of the brushes. Fig. 9 is a diagram showing the electrical connections.
2 designates a support or casing which may be of any shape and size for its intended purpose. In the present embodiment of my invention, this casing or support is made in the form of a rectangular box.
Distributed over the top 6 of the casing 2, in any desired manner, is a series of contact devices 3, each of which comprises a tube 5 extending through the cover 6 and having an inwardly extending bottom flange 8, a pin extending through the tube and having an enlarged upper portion 9 extending above the top of the .tube, and a reduced lower portion 10 extending below the bottom of the tube, and a spring 11 encircling the lower reduced portion 10 and extending; between the flange 8 and the bottom of the upper enlarged portion 9 of the pin. The tops of the tubes 5 are flush with the top of the cover 6, and each tube 5 is held in place by frictional engagement with the cover 5 Specification of Letters Patent.

or by any suitable means. The contact devices 3 are electrically insulated from each other by the cover 5 which, in the present instance, is made of wood.
The casing 2 may be made in the form of a couch to receive the body of a person, and the contact devices 3 distributed over the top of the couch so that many parts of the body of a person upon the couch will con tact with the devices 3 which yield against the action of the springs to adjust themselves to fit and engage irregularities in the surface of the body.
Vithin the casing 2 is a commutator 12 which comprises a standard 13 of insulating material upon which are supported an inner circular series of contact plates 15 and an outer circular series of contact plates 14. The contact plates 1-1- and 15 are arranged in spaced relation to each other and the spaces between the plates of one series are opposite the central portions of the plates of the other series, as shown. The plates 1 1 and 15 correspond in number with the contact devices 3, and each plate of the commutator is electrically connected with one of the contactdevices by a wire 16, one end of which is connected to the commutator plate, and the other end of which is connected to the lower end of the pin 10 of one of the contact devices.
Mounted on the standard 13 within the in nor series of plates 14 is a contact ring 17, and mounted on the standard 13 within the ring 17 is another contact ring 18; Extending centrally through the rings 17 and 18 and series of contact plates 14 and 15, is one end of a shaft 19, the other end of which is mounted in a'suitable bearing 20. Secured to the shaft 19 adjacent the standard 13, is a disk 21 of insulating material, which carries two brushes 22 and 23, which are pressed into engagement with the contact rings 17 and 18 respectively. The disk 21 also carries two brushes 24 and 25 which are pressed into engagement with the two series of plates 14 and 15 respectively. The brush 22 is connected to the brush 24 by a wire 26, and the brush 23 is connected to the brush 25 by a wire 27.
Secured to the shaft 19 is a worm wheel 28 which is engaged by a worm 29 on the power shaft 30 of any suitable motor 31, preferably electrical, whereby, when electric current is supplied to the motor, the worm 29 will on 1 gage the worm wheel 28 and rotate the shaft 19 and therewith the disk 21, and cause the brushes 2 1 and 25 to successively engage the plates 14: and 15 respectively, while the brushe. and 23 remain in constant engagement with the plates 17 and 18 respectively.
The electric circuit (not shown) for the motor 31 is interrupted by a switch 32 on the exterior of the casing 2. By closing and opening the switch 32, the motor 31 may be started and stopped as desired.
Connected to the rings 17 and 18 are the terminal wires of an electric circuit in which is included an adjustable inductive resistance device 33 and two switches 34 and as follows. Leading from the outer contact ring 17 and connected to the arm 36 of the switch 3 1, is a wire 37. Leading from the contact piece 38 of the switch 3 1 to the contact piece 39 of the switch 35, is a wire 40, which is interrupted by an electrical battery 41. Leading from the contact piece 12 of the switch 3 1 to one element d3 of the circuit making and breaking device of the induc tion device 33 is a. wire at. The element 43 of the circuit making and breaking device is connected to one end of the inner primary coil 1-8, and the other end of the coil 18 is connected to the wire l-O. Surrounding the primary coil 18 is a. secondary coil 4-9, one end of which is connected by a wire 50 to the inner contact ring 18, and the other end of which is connected to the wire etO. Thus it will be seen that when the switch 35 is closed, current will flow through the circuit to the contact rings 17 and 18, and that when the arm 36 of the switch 3 1 is in engagement with the contact piece 38 the primary coil 18 will be operative to produce one degree of current, and when the arm 36 of the switch is in engagement with the contact piece 412, both the primary and secondary coils 4E8 and 49 respectively rill be operative to produce a greater degree of current. The intensity of the current may be still further regulated by adjusting the bar 51 which extends through the primary and secondary coils 18 and 41-9.
The operation is as follows :The switches 32 and are closed, thus setting the motor 31 in operation, and closing the circuit for the contact devices 3. The operation of the motor causes the brushes 2st and 25 to successively engage the plates 1 1 and 15 respectively, and, as previously explained, current flows from the electric circuit to the contact rings 17 and 18, the brushes 22 and 23, the wires 26 and 27, and the brushes 2e1- and 25 respectively. As the brushes 24 and 25 are successively engaged with and dis engaged from the commutator plates 14; and 15 respectively, electric current is supplied to the contact devices 3 in prescribed order; that is to say, as the brushes 2% and 25 sweep over the plates 1e and 15 respectively, two separate contact devices 3 are supplied with electric current each time the brushes 2% and 25 are engaged with two adjacent plates 14 and 15 respectively, during the rotation of the brushes. Therefore, if the two contact devices supplied with current are in contact with the body of a person, the body will receive the current. Thus it will be seen that as the brushes 211 and 25 are constantly making and breaking connection with the plates let and 15, different parts of the body of a person engaged with the contact devices are thus intermittently subjected to the electric current in prescribed order.
I claim 1. The combination of a support provided with a surface adapted to receive the body of a person, a pair of electrically separated contact parts projecting from said surface, an open electric circuit, and automatic means for connecting said pair with said circuit at predetermined intervals, one part to one terminal of the open circuit, and the other part to the other terminal of the open circuit.
2. The combination of a support provided with a surface adapted to receive the body of a person, a pair of electrically sepa rated yielding contact parts projecting from said surface, an open electric circuit, and automatic means for connecting said pair with said circuit at predetermined intervals,
one part to one terminal of the open circuit,
and the other part to the other terminal of the open circuit.
3. The combination of a support provided with a surface adapted to receive the body of a person, a series of pairs of electrically separated contact parts projecting from said surface, an open electric circuit, and automatic means for connecting said pairs with said circuit in prescribed order, one part of a pair to one terminal of the open circuit, and the other part of a pair to the other terminal of the open circuit.
1.Tl16 combination of a support provided with a surface adapted to receive the body of a person, a series of pairs of electrically separated, yielding contact parts projecting from said surface, an open electric circuit, and automatic means for connecting said pairs with said circuit in prescribed order, one part of a pair to one terminal of the open circuit, and the other part of a pair to the other terminal of the open circuit.
5. The combination of a support provided with a surface adapted to receive the body of a person, a pair of electrically separated contact parts projecting from said surface, an open electric circuit, automatic means for connecting said pair with said circuit at predetermined intervals, one part to one terminal of the open circuit and the other part to the other terminal of the open circuit, and means for regulating the intensity of the electric current. 6. The combination of a support provided with a surface adapted to receive the I body of a person, a pair of electrically sepa- 1 rated yielding contact parts projecting from said surface, an open electric circuit, automatic means for connecting said pair with said circuit at predetermined intervals, one i part to one terminal of the open circuit and the other part to the other terminal of the open circuit, and means for regulating the intensity of the electric circuit.
