MASSAGING IMPLEMENT Filed Dec. 8. 1950 Wig llglgyf//j l Patented Feb. 27, 1934 UNTE STATES ATENT QFFICE 12 Claims.

This invention relates generally to that type of massaging implements, such as are used in barber shops, beauty parlors and homes; and it reiates particularly to such implements as are vacuum operated and provide both a suction and massage eiiect by the applicator.

The objects of the invention are to provide an implement of the nature specified so constructed that it will be light in weight, sturdy in construction, possess but few parts, be economical to manufacture and be efcient in operation.

Other objects and advantages of the invention will appear from the detailed description of the device to be presently given.

The invention consists of structural characteristics and relative arrangement of elements, which will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying one sheet of drawings, similar reference characters indicate the same parts in the several gures of the drawing, in which:

Figure l is a central vertical sectional View oi an implement constructed in accordance with the present invention;

Figure 2 is a similar View oi a modified form of the implement;

Figure 3 is a similar View of a certain piston and valve employed in the implement and showing a further modification; and,

Figure #i is a transverse horizontal sectional view on the line IV-IV of Figure 1.

Referring, in the first instance, to Figures 1 and 4 of the drawing, there is illustrated a vacuum message implement which is provided with a cylindrical casing adapted to be held by the hand of the operator. The upper end of this casing is closed by means of an upper removable plug or head 11, and the lower end is similarly closed by means of a, lower removable plug 12.

A rubber vacuum massage cup 13 is provided with a threaded stem 14, which is screwed into a central opening 15 in the lower plug or head 12, a lock nut 16 serving to retain it in proper position.

Through the center of the cup 13 and stem 14 there is formed an opening 17, which is in actual alinement with a similar opening 18 in the inner web of the plug 12 and also in axial alinement with a central opening 19 in the upper plug 11. These alined openings serve to receive and guide a valve spindle 23, as will be later described.

Slidably mounted within the casing 10, there is provided a cylindrical piston 20, which is normally maintained in raised position by means of a coiled spring 21 interposed between the lower (Cl. 12S-40) end of the piston and the inner face of the lower plug 12.

The upper end of the piston 20 is provided with a seat adapted to receive a valve 22 Xedly mounted upon a spindle 23, which is slidably guided in the

openings

18 and 19, as shown. This valve 22 is normally maintained in raised position, with its upper face in contact with the inner face of the upper plug 11 by means of a coiled spring 24, smaller in diameter than the spring 21, which is interposed between the lower face of the valve 22 and the upper face of the lower plug 12.

The valve 22 and piston 20 receiving interior chamber of the casing 10 are in communication with the outer air through the plug 11 by means of a circular series of apertures 25, and are likewise in communication with the interior of the rubber cup 13 by means of a circular series of apertures 25, which lead through the inner web of the plug 12 and into the central stem receiving opening 15, and communication is thence through the opening 17.

1n the side wall of the casing 10 there is a port 27 leading from the lower portion of the chamber to a duct 23, which terminates in an outstanding stem 29 formed on the casing 10 and adapted to receive the end of a hose or other iiexible connection, not shown, which will lead to any common and well known pump or vacuum creating device of any desired make.

In operation, the parts will be initially in the positions illustrated in Figure 1.

The vacuum creating device is started in action and air is withdrawn from the lower portion of the chamber below and within the piston 20. A partial Vacuum is thus created within such portion of the chamber and within the cup 13, which has been forced or rested cn that portion of a person to be massaged. The cup will thus be caused to gently adhere to the skin of said person upon whom the implement is being used, and the piston 20 with its valve 22 will be drawn down by the outside atmospheric pressure against the action of the

springs

21 and 24.

The tension of the inner spring 24 is such that before the spring 21 is fully compressed, the valve 22 will be lifted from its seat on the piston 20, thus admitting the external air from the vupper portion of the chamber through a passagewayin said piston to the lower end of said cylinder, and breaking the partial vacuum which has been created therein. The spring 21 will then force the piston upwardly. the valve 22 will be reseated and the cycle will repeat itself.

These cycles follow one another with great rapidity so that a continuous vibration or" the piston 20 and valve 22 is effected, which vibration is transmitted, in part, to the casing l and to the rubber cup 13.

Thus, it will be seen that the rubber cup, known as the applicator, is caused not only to gently adhere to the skin of the person receiving treatment, but is caused to be vibrated or massaged. As the implement is moved about, this combined suction and vibration will have a very pleasant and beneficial massaging eiect.

In Figure 2, there is shown an implement of the same general type, as already described with reference to Figures l and 4, but in which several niodined forms of construction are employed. In this form or the implement, the casing has the former upper plug l1 a lower plug 12a, the latter being provided with a projecting central stem 142, upon which a rubber cup 13a is secured by means of a lock nut 16e.

A piston 2Ga has its lower portion closed save for a circular series of apertures 20b and serves as a guide for the lower end of a valve spindle 23a upon which the valve 22 is rigidly mounted. This valve 22 is, in the present instance, normally maintained in raised position by means of a coiled spring 24a interposed between the upper face of the plug 12a and a collar 30 mounted or fixed upon the valve spindle 232L at a point below the closure or apertures 2Gb oi the piston 20a.

The lower plug 12a is provided with a central opening 15=l and a circular series of apertures 26St which establish the communication between the cup 13 and the lower portion of the vacuum chamber within the casing 10.

A stem 29a is adapted to receive a iexible air pipe 31 leading to the pump or other vacuum creating device, and is protected by a rubber casing 32.

Other features oi this form of implement are the same as those illustrated and described with reference to Figures 1 and 4, and are indicated by similar reference characters.

In the operation of this form of the invention, when the pump is started, partial vacuum is created in the cup, in the lower portion of the chamber, and within the piston, as heretofore explained with reference to Figure 1, and the piston 2()a and its valve 22 are drawn downwardly. If the compression of the relatively small spring 24a is insuicient to liit the valve 22 from its seat, the bottom of the valve spindle 23a will contact with the upper face of the lower plug 121l and further downward movement of the piston a will withdraw the seat from the now stationary valve 22 and the partial vacuum will be broken, as before, thus permitting the springs 21 and 24a to restore the parts to their original positions.

In Figure 3, there is illustrated a further modification of the valve structure. In this instance, the piston 20a and the valve 22 are the same as shown in Figure 2, with the exception that the valve spindle 23a is provided with a collar 3Wl attached at its lower end, and the valve 22 is maintained in seated position by means of a coiled spring 24h interposed between the upper face of the collar a and the partially closed bottom of the piston 20H. The sole function of this spring is to maintain the valve upon its seat until the spindle 23u contacts with the lower plug 12 or the casing, as it can readily be understood that there is no compression of the spring during the downward movement of the piston and its valve, as has been the case in the forms of the invention previously described.

While the terms upper and lower, and upward and downward have frequently been employed herein and will be similarly employed in the claims, which are to follow, it is to be understood that these terms are purely relative, as the instrument may be held in any desired position whatsoever.

Other changes, modifications and alterations in the shape, form, and arrangement of the parts will quickly suggest themselves to those skilled in the art, and it is to be understood that such variations are to be regarded as forming part of this invention, as long as they fall within the scope of the following claims.
