My invention relates to vibrators and more particularly to a device for vibrating a massage tool or head in which the tool is inside to vibrate at a rapid rate, by means of a m0vable armature associated with an electromagnet which magnet is energized from a source of pulsating or alternating current so as to alternately contract and release the movable armature and thus set up a rapid rate of vibrations.
It is'a purpose of this invention to provide a device of this character which shall be easy to manipulate or hold of an extended handle.
without the provision It is also a purpose of this invention to pro videa vibrator of this character with a container or housing that may readily be grasped by the hand of the operator and firmly held so that there is no danger of it twisting out of the operators hand and so that it may be properly directed to give the most advantageous results.
Another object of this invention is to provide in a device of this character an open face handle container for the electro-magnet in which the vibrating armature serves to substantially complete the container ting within the open side thereof.
It is also a purpose of this invention to provide a vibrator of this character with a container whichv is adapted to serve as a handle and which contamer may be readily detached in sections from the vibrator to permit access tothe interior thereof.
' A further object of the invention; is to provide in a device of this character novel means for resiliently supporting the movable armature on the electro-magnet.
Other objects and advantages of the invention will appear as the description proceeds in connection with the accompanying drawings. owever, it is to be distinctly under stood that I do not intend to limit myself to the exact details shown or described, but that I intend to avail myself of all such modifications as would occur to one skilled in this art and as fall within the scope of the claims.v
In the drawings:
b fit- V y then isfor a much longer Fig. 1 is a side View partly in section illustrating my device;
Fig. 2 is a view looking upwardly at Fig. l with the massage implement removed; and
Fig. 3 is a section on th line 3-3 of Fig. 1.
Referring nowin detail to the drawings, my vibrator consists of the electro-magnet having. the core 5 made up of a series of laminations as illustrated in Fig. 3 which core is provided with a plurality of polar projections 6, 7, and 8 all of which have their end portions lying in substantially the same plane. The energizing coil 9 is wound about the central projection 7 and may be connected to a suitable source of current by means of the conductors 10 and 11 through a circuit closing and opening device indicated generally by the numeral 12 and operable by means of the lever 13.
Movable armature 14 extends across the end faces of the projections 6, 7, and 8 and is secured to the core 5 by means of the flat spring 15 which is riveted to the armature or otherwise suitably secured as indicated at 16 and then is bent upwardly as at 17 to extend along the side of the projection 8 a substantial distance from the end face thereof and bent inwardly as at 18 so as to lie directly against the core.
Bolts 19 and 20 or other suitable securing means serve to rigidly secure the end of the spring tothe side of the core.
From the above description it wi l be seen that the armature 14 is resiliently supported in a very simple manner by means of the spring 15 so as to permit vibration of the tro-magnet. This mounting also permits the use of a heavy flat spring to support'the armature and this spring having comparatively small motion relative to the movement of the free end of the armature 14 will last time than would be the case if it were necessary to use light springs or springs having the same degree of movement as the armature.
The armature has at 21 a projecting shaft to which a massaging device indicated at' 22 may be secured. As indicated in F i 1 this massaging device is screw threaded mto the shaft 21 so that one massaging device may bereplaced readily with another of a different character when desired.
The entire electro-magnet is enclosed b means of a container consisting of the bac piece 24 which as indicated in Figs. I and 3 is rigidly secured to the core of the magnet by means of screws indicated at 25 and 26 screw threaded intothe core, and a pair of side pieces 27 and 28 which extend down over the sides of the projections 6, 7, and 8 and are outwardly bulged or bent to accommodate the core 9. These bulges are indicated more clearly at 29 and-30 in 2. At the opposite ends of the side pieces 27 and 28 they are bent toward each other as indicated at 31 and32'to enclose the ends of the electro-magnet. The side pieces are held in place by means of screws such as indicated at 33 and 34 and 35 so that they may be readily detached from the core and removed to permit accessto the interior of the device.
The bottom of the container formed by the back piece and side pieces just described is left open to permit free action of the vibrating armature 14 which extends substantially the full length of this open side and serves to substantially complete the enclosure of the electro-magnet. It is obvious, however, that the armature need not be as wide as shown merely to form the closure, but this makes a very simple and easily constructed manner of so enclosing the electro-magnet as to protect it from the accumulation of foreign matter therein. The back piece 24 is extended as indicated at 38 and has the sides thereof extended downwardly and bent toward each other as" indicated at 36 and 37 in Fig. 2 to form an inclosure for the switch element hereinbeforereferred to. o a
The container formed by the aforementioned elements serves not only to enclose the electro-magnet but in view of its relatively small size and convenient shape, it is used as the handle by which the device may be held and, by the use of the container as a handle it is unnecessary to provide the usual extended handles found on devices of this character. This body portion which may be gripped by the hand of the operator makes a much better handle than the extended han- I dle since it is practically impossible for the vibrator to twist or shake itself out of proper position in the hand.
By having the weight distributed lengthwise of the casing and having the vibrator carried by the armature adjacent the front end of the casing so as to have the work pressure and maximum reaction at the one end of the casing in order to cause a turning movement in a plane lengthwise of the casing, the vibration at the other end is materially lessened. By having the-tail piece in a generally diagonall opposite position with respect W the place 0 pressure application, the tum ing movement can be .opposed by the smaller fingers of the operators hand with but little of the tiring pounding or vibration upon them.
The heavy core of the armature together with the winding and the housing makes a heavy mass that is not subject to an objectionable reaction due to the vibrationv of the light armature 14 and the massage tool carried thereby. Furthermore, in view of the manner in which the armature is mounted, heavier pressure on the massaging device brings the armature closer to the electro-magnet and thus increases the magnetic pull so that the degree of viblation obtained is substantially increased at will without adjustment.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. A vibrator comprising an electro-magnet having a core provided with polar projections, a spring having one end secured to the side of said core, and projecting toward the end faces of said projections and an armature secured to said spring adjacent the free end thereof and extending across the end faces of said projections.
