VIBRATOR.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application mea January 3o, 1914. serial No. 815,415.

T0 all whom it may concern Be it known that I, LEAL L. MONTGOMERY, a citizen of the United States, and a resident of Superior, in the county of Douglas and State of vWisconsin, have invented a new and Improved Vibrator, of which the following is a full, clear, and exact description.

My invention relates to vibrators used for massage purposes, and has reference more particularly to vibrators actuated by elastic uid.

The object of the device is to provide a simple, compact, strong and inexpensive device which 1s automatic in its action, which has few parts to get out of order and therefore reduces the cost of the device and its 11p-keep to a minimum.

I attain the above object by providing a plunger adapted to be actuated periodically by elastic iuid operable means, with means for returning the plunger to its normal position.

The invention consists of the construction and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this speciiication, in which like characters indicate corresponding parts in all the views and in which:

Figure 1 is an axial, vertical section through an embodiment of my invention; Fig. 2 is a similar view showing the plunger under the action of the piston; Fig. 3 is a perspective view of the device; and Fig. 4f is a section on line 1 -4, Fig. 1.

Referring to the drawings, 5 represents the shell or cylinder closed at the ends by means of plugs 6 and 7, preferably threaded therein. Air inlets 8 are provided in the cylinder adjacent the plugs 6 and 7; and similar air outlets 9 are provided in the cylinder, which are closer to the plugs 6 and 7 than the inlets 8. Said outlets 9 are interconnected by a tubular member 10 forming an extension of the cylinder and which extension is provided with a lateral aperture 11 formed in the central lateral extension 12 of the shell or cylinder 5. Threaded with one end into said aperture 11 is a tubular member 13 which forms a stem or support for a handle 14 to which the cylinder 5 is securedby means ofanipple 15, to `which nipplethe intake 16 of `a vacuum pump can be secured. Between the projection 12 and the handle 1% a rubber washer 17 is interposed, whereby the vibration on the handle due to the reciprocating motion of the parts in the cylinder is're duced.

Mountediwithin the cylinder 5 is a valve formed of two cupfshaped members 18 facing each other and interconnected by means of a stem or rod 19. The length of each of said cup-shaped members 18 is such that when the vmember covers the inlet 8 it uncovers the corresponding outlet 9, and vice versa. The length of said rod 19 is such that when Ione of the members 18 uncovers the air outlet 9, the other of said members uncovers the inlet 8, z. e., when the valve uncovers the air outlet at one end, it simultaneously uncovers the air inlet at the opposite end. Mounted to slide on the rod i9 is a sleeveA 21 forming the piston in the cylinder, the ends 22 of which are reduced to fit snugly into the cups 18. Each of said cups at the bottom thereof carry a resilient member y23 which is adapted to' be engaged by the corresponding extremity of the reduced end 22 of the piston, thereby closing the apertures 24E provided in the bottom of the cups, which apertures establish communication between the spaces a and ZJ at each side of said bottom.

The plug 7 is provided with an axial aperture 25 enlarged at the inner end of the plug, as shown at 26. Engaging the aperture 25 is a plunger 27 the head 28 of which fits into the enlarged portion 26.` A

coil spring 29 carried by the plungerV is` also positioned in said enlarged portion and adapted to maintain the said plunger in normal position. The projecting end of the plunger 27 is threaded and thereon adapted to receive members suitable for massage` of which 30 is one. The head 28 of )said plunger is provided with a recess into which is fitted a bumper 31, preferably of rubber,

against which the valve strikes when the piston moves toward the plunger, as shown in Fig. 2. The plug 6 at its inner end is also provided with a bumper 32 against which the opposite end of the valve is adapted to strike when the same is moved away from its engagement with the plunger by the movement of the cylinder in the direction opposite to that stated before. the position of which is shown Ain Fig. 1. Both of said bumpers 'are,intendedv for the purpose of reducing the vibration caused by the reciprocating movement of the plunger and valve in the cylinder."

The action of my device is as follows: The air drawn by the suction pump fromv the spaces a and Z), see Fig. 1, through the out let 9, reduces the pressure therein and permits the atmospheric pressure acting through the inlet 8 to force the piston 21 to move yfrom its position shown in Fig. 1 toward the cup18 at the right side of the plunger in saidigure. The momentum of said piston, when it strikes the bottom of the cup 18 nieves the valve therewith and causes the same to strike the bumper 31, thus forcing the plunger out ofthe plug 7. This movement` of the valve uncovers the air outlet 9 at the opposite end ofthe cylinder, closing the inlet 8 at the same yend, thus reducing the pressure in thespaces al and 6; formed by the sleeve, cup and cylinder atvthe said end of the cylinder and causing the return of the piston 21 and the valve therewith to i the position shown in Fig.` 1; thus a complete cycle of the piston andv valve have been described. The purpose of the coil spring 29 in the plug 7 is not only to restore .the

. plunger 27 to its normal position but also to reduce the shock causedby the valve striking the bumper 31 of the plunger.

The sleeve or piston 21 and the cup-shaped members 1S are made to nt snugly into the cylinder so as toreduce the leakage of air therebetweento a minimum. Furthermore, the sliding movement of said piston or sleeve 21 and the stem 19 ofthe valve is of such a nature! as to produce a momentum which l will vnot only be able to carry the valve to cylinder.

It is evident that v-ar-ious changes might be made and modications resorted to i-n the construction and arrangement ofthe par-ts described without departing `from the spirit andv scope-of my invention; hence, .Ido not wish to limit myself to the exact construction shown. v

Having thus described my invention, I claim as new and desire to secure 'by Letters Patent: y 1. ln a vibrator, a plunger;elastic-liuid operable means for actuating. the plunger periodically; a member carried rby the plunf ger and adapted to be engagedV by Vsaid .fluid operable means vwhereby the noise `and., shockl (1f-engagement is diminished; mea-ns for returning said plunger toits normal sition.
