MOVEMENT-CURE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 745,021, dated November 24, 1903.

Application filed June 23,1903. Serial No. 162,775. (No model.)

To all whom it may concern.-

Be it known that I, JOHN J. LEWIN, a citizen of the United States, residing at Paloalto, county of Santa Clara, State of California, haveinvented an Improvementin Movement- Oure Apparatus; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a movement-cure apparatus which is especially designed to produce vibrating motion of an elastic arm, so that such motion may be employed for any purpose to which it may be applicable.

It consists in the novel arrangement of an electromagnet, an armature, a peculiarly-constructed contact making and breaking spring upon which the armature is carried, and a curved arm having a rounded knob or point upon the end carried by the armature, and in conjunction with this of a regulating-arm and stop.

Referring to the accompanying drawings, Figure 1 is a side view of my invention with part of casing in section, showing armature retracted. Fig. 2 is a partial view of same with armature in contact with magnet. Fig. 3 is a transverse section on line a: m, Fig. 2. Fig. 4 is a transverse section on line 00 m, Fig. 2, showing permanent magnet. Fig. 5 is a plan view of controlling-lever.

It is the object of my invention to provide a vibrating arm and a means for regulating or stopping the stroke and the intensity of the vibration.

As at present shown, the device is especially applicable to apparatus for the treatment of the skin by the action of the vibrating arm.

l The device as here shown consists of an insulating-base A, having mounted upon it a frame of any suitable description, as at 2, in which is supported an electromagnet 3. Upon the frame is fixed an elastic or spring arm 5, and this arm is made of considerable width, so as to give it the desired amount of stiltness between the point of attachment and the upper end of this portion. The armature 6 is riveted or otherwise secured to the upper end of this portion of the spring and in such a manner that it stands across the two poles of the electromagnet and at a short distance away from them. The spring-arm is continued up, as at 7, beyond the point where the armature is secured to it, and this upper portion of the spring-arm is made very much more slender and of less strength than the lower portion. Opposite the upper end of this extension 7 is the post 8, having an adjusting-screw 9, the point of which is so placed as to just contact with the end of the spring 7 when the armature is free from attraction. From the upper end of the armature the wire 10 extends to a considerable distance and has the upper end rounded or formed with a knob, as at 11. This wire is of such length as to have considerable elasticity and is bent into a segmental curve, as shown.

12 represents binding-posts with which the conducting-wires of a battery are connected, the current passing from one of said posts through the coils of the electromagnet, thence to the post 8 and through the adjusting-screw 9 and through the spring-plate 5 7 to the frame 2, and thence to the other bindingpost and to the battery. When the magnet is energized, the armature 6 will be attracted and contact between the spring 7 and the adjusting-screw 9 will be broken. The current being thus shut off, the armature will again be released, and the action of the spring will throw it outwardly until the tip of 7 again contacts with the screw. Thus the vibration of the armature and the arm 10, which was carried by it, will be efiected. The peculiar arrangement of the spring 5 7 is such that the upper part 7 of the spring will normally bend outward a little from the armature, the outward spring taking place from the point where the armature is bolted to the upper end of the as the armature moves backward the tip 7 of the spring contacts with the adjusting'screw and again completes the circuit; but the mo mentum caused by the spring 5 and the ICO weight of the armature and the length of'thearm 10 will throw the armature back until it momentarily closes against the tip 7. The lower end of the spring is of such a tension as to press the upper end of same spring against the armature and also against the contact-screw in the binding-post, making contact. When the current is completed through the coils and armature-spring, the upper end of spring will for some time remain in contact while the armature has moved from the contact. I claim by such an arrangement I get longer and harder throw by having the contacts remain longer in contact, and by having a curved vibrating rod it gives more of an end-thrust blow. These alternating movements take place with great rapidity and produce a very rapid movement of the vibrating arm. In order to regulate the length of the stroke of this arm I have shown a lever 12, which has a cam or eccentric shaped face, as at 13. This lever is pivoted with relation to the arm 10 so that it may be turned, and by pressing the arm forward'the armature will be moved closer to the poles of the magnet, and the distance between the ar. mature and the spring. 7 will be correspondingly increased. Thus the movement necessary to make and break the contact will be reduced so greatly that the movement of the outer end of the arm 10 will be almostinvisible. Thus any desired character of vibration may be imparted to the arm 10 and correspondingly transmitted to the part to which it is to be applied. B'yturning the lever to the full extent a notch 14 in the end of the lever will be pressed against the arm, and will thus prevent any vibration thereof. By the addition of a permanent magnet bent as shown it may be bolted or secured to the frame, so that the separated poles will extendacross the front of and in opposition to the electromagnet. This construction is es-f pecially valuable when an alternating current is employed, and its effect is to increase the energy of each alternate vibration. In this manner Iain able to regulate the length of stroke of the arm and the character of the vibrations to the minutest degree.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-

1. A movement-cure apparatus comprising a frame or casing containing an electromag net; a spring and an armature fixed thereto; a contact-point between which and the poles of the magnet the armature is adapted to vibrate; and an elastic arm connected t0v the armature and extending through the case and tov such distance beyond the same that it is capableof imparting rapid blows to the hum an body.

= justing-screw through which an electric current passes to the spring and frame, said extension of the spring adapted to contact with said screw; .and an arm extending from the free end of the armature said arm made elastie and having such length that it is capable of imparting rapid blows to parts of the hu man body. i

3. A movement-cure apparatus comprising a frame; an electromagnet therein; a spring secured at one end; an armature having one end secured to the spring near the point of attachment of the latter whereby the remaining portion of the spring is unattached to the armature and is contiguous to the back thereof; a contact-point between which and the armature the extension is located said extension normally bending away from the armature and adapted to remain in engagement with the contact until the main portion of the spring has about returned the armature into contact with the poles of the magnet, said'extension then moving away from the contact to break the current and deenergize the magnet; and an elastic arm extending from the :free end of the armature and having such length that it is capable of imparting rapid blows to the human body; and means for regulating or entirely stopping the vibrations of the arm.

4.. An electromagnet and supporting-frame, a spring fixed to. the frame, an armature having one end fixed to the spring near the base thereof so that the armature extends in front of the magnet-poles and the free extension of the spring is contiguous to the back of the armature, said free extension of the spring made. weaker than the remaining portion thereof whereby the armature may move relative to said weaker portion when the magnet is energized, a permanent magnet carried by the frame with its poles exterior to the armature and in opposition to those of the electromagnet,a con tact-point between which and the electromagnet, the vibrations occur, and an elastic arm connected to the armature and curved in the direction of its length and having such length that it is capable of striking rapid blows upon parts of the human body.

In witness whereof I have hereunto set my hand JOHN J. LEWIN. Witnesses:

S. H. NoURsE, JESSIE C. BRODIE.
