EDWIN S. HUHPHBEYS; OE CLEVELAND, OHIO, ASSIGNOR TO THE ROGERS ELECTRIC I LABORATORIES COMPANY, OF CLEVELAND, OHIO, A CORPORATION.
HIGH-FREQUENCY ELECTRICAL APPLIANCE Application filed December 27, 1920. Serial a... 433,298.
To all whomtt may concern Be it known that I, EDWIN S. HUM- PHIiEYs, a' citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certainnew and useful Improvements in a High-Frequency Electrical Appliance, of which the following is a specification.
My invention relates to a therapeutical appliance in which a high-frequency electrical current is produced and discharged through an electrode securedwithin one end thereof, and the appliance is'especially constructed to promote the following results; to permit a free circulation of air-through the appliance to keep the body and parts therein cool during operations; to allow the working parts and end cap to be readily remove and handled as a unit; and to establish sprin seating relations between the arts and t e body to prevent looseness, displacement and poor contact.
In the drawings accompanying this application, Fig. 1 is a side view, partly in section, of my improved appliance, and Fig. 2 is a view at right angles to Fig. 1 on line 2 2, thereof. Fig. 3 is a cross section on line 33 of Fig. 2, and Fig. 4 is across section on line 4-4, of Fig. 1. Fig. 5 is a view of the front end of the appliance. Fig. 6 is a diagram of the electric circuit used in the appliance.
The invention comprises a cylindrical body 2 of hard rubber having-a reduced nose portion 3 provided with ribbed and fluted central opening 4 which communicates with the round hollow interior or large chamber 5 extending the full length of the body. A clamping holder or socket 6 is confined within the inner shouldered portion of opening 4, and this socket is adapted to receive and grip the stem of any suitable high-frequency electrode introduced into 0 ning 4. The opposite end of body 2 is. apted to be closed or rtly closed by a screw cap 8 having a dduble saddle 9 bolted upon its inner face directly opposite a central 0 ening 10 therein. A current interrupter ls mountedon saddle 9,, and this interrupter comprises'an adjusting contact screw 11 adapted to project through openinglO into screw-engagement with a threaded opening in saddle 9 and opposite a vibratory armature 12 mounted on one head 13' of the interrupter coil 14.
. the same.-
The heads of coil 14 consist of round flatvide air s aces 15 opposite body 2, and the round y of the'coil is at one side of the center of the heads and of less diameter than chamber 5 to permit air to circulate around the coil and through body 2. The air enters chamber 5 through opening 10 and several other air entrances 16 in screw cap 8, and passes out of the fluted portions of opening 4 around the stem of the electrode which is of approximatel the same diameter as socket 6.
A high-frequency coil 17 comprising a primary and secondary winding is placed in advance of coil 14, and it also comprises round fiat pieces 18 at its opposite ends with portions removed at the edges to seat said coil 17 centrally within chamber 4 and so that the air may circulate freely around 8 18 of thecoil apart from the body to permit the air to pass into fluted opening 4. The two coils 14 and 17 are jointly supported upon saddle 9 and connected together in a yielding manner by a pair of tie rods 20-20. which also serve as electricalconductors in the working circuits for the coils, see Fig. 6. .7 Thus, rod 20 extends lengthwise at one side of coil 17 and through both of its end pieces 1313, and is fastened at one end by a nut 21 to one arm of saddle 9, see Fig. 1, while the opposite end 22 is bent toextend at an angle to the major portion across the front end of the'coil to the opposite side where a straight terminal portion 23 is again bent to project through and seat the rear end piece 18 of coil 17 where one end of the secondary winding 24 may be connected therewith. The second tie rod'20 is fashioned like the first and placed on the opposite side of coil 14 with its angular portion 25 extending cross-wise to the angular portion 22 of rod 20, and a straight terminal portion .26 is also formed at the end of this cross portion 25 so that it may project through and seat end piece 18 and connect with the opposite end of winding The core 19 of coil 17 projects.
, 24, see Fig. 1. Rod 20' is connected with coils removably I within said body.
high frequency electrical appliance, comprlslng a tubular body adapted to receive an electrodewithin' one end thereof, and a removable cap at the opposite end of a lead-in wire and rod with saddle 9, and thus both are laced in the electric circuit. Furtrmore, t e crossing rtions of these two rods provide a yielding spring connection between the twolcoils 1d and 17 so that when end cap 8 is screwed into the open end of body 2 and contact is made between core 19 and socket 6 all said parts are placed under spring compression and firmly seated and held in their respective working positions within the body. A condenser 28 is mounted at one side ofcoil 1d and bound to it by a piece of tape 29, and one way of electrically connecting the various parts herein described in an opera tive circuit is shown in Fig. 6, but no claim is made herein for the circuit nor is it intended that the invention should be limited to-such a specific circuit.
