Application led February 21, 1913. Serial No. 749,936.

To all whom 'it may concern:

Be it known that I, GEORGE ELMER GRAY, citizen of the `United States, residing at Des Moines, Iowa, have invented certain new and useful Improvements in Pumpin Means4 for Massage Devices, of which the following is a specification.

My present invention relates to improvements in massage apparatus of the type in which water from a faucet is used to secure the necessary suction or partial vacuum.

The invention has among others for its be readily applied to and removed from any ordinary faucet, which will secure a maximum amount of suction, and give an eiicient massage action; and whichv will be of simple and economical construction.

With these and other objects-in view, the invention includes the novel 4features of construction and arrangement and combination of parts hereinafter described and particularly defined by the 4appended claim.

In the drawing Figure 1` is a central longitudinal section of my improved apparatus; Fig. 2 is a section on line 2 2 of Fig. 1; Fig. 3 is a section .on line 3--3 of Fig. 1; and Fig. 4 is a detail view.

Referring by reference characters to this drawing, the numeral 1 designates the outer shell of the suction generator of myap aratus, which may be formed of any suitah material', preferabl by casting. It is of substantially cylin rical shape, as shown, and provided with an overturned u per edge 2 forming a downwardly extending annular flange. This flange is adapted to engage a special coupling or. connecting washer 3 which comprises-a body portion 3 of .tapered or truncated cone shape adapted to frictionally engage lthe nozzles of faucetsof various sizes. At its upper-.end the body has a cylindrical portion `3 provided at its lower edge with an outwardly extended and upwardly elongated annular flange 3 adapted to rest in the recess formed beneath the overturned upper edge 2 of the body 2 and the internal annular shoulder. The upper edge b of the washer is preferably substantially flush with the up er edge of the body 2. The washer is furt er rovided with a transverse rib c on one 'si e.

The 'shell l of the generator is provided, a short distance below the lower end of the washer, with a horizontal partition 4, which has a central depending injector nozzle 4 lev arranged axially of the body of the washer. Below the partition 4 is a' second partition 5 having a downwardly tapered portion 5a terminating in a depending tubular portion 5b axially in line with the injector nozzle 4. Beneath the lower end of the tubular por- Vtion5b and spaced therefrom is placed a deiiecting disk 6 supported by the portions 6a. The water flowing down through the injector nozzle 4a into the cone 5 and tube or 'leg 5b causes a suction in the space or chamber between partitions 4 and 5, and

as this chamber is in communication with applicator 8 through nipple 9 and hose 10, the suction on vthe applicator is produced. The ldwer edge of the shell lis curved inwardly and upwardly, as indicated at 7, so as to provide an annular trough with its inner edge beneath the outer edge of thev disk 6.

The portion 4'a is preferably tapered,ia s` shown, and provided with a beveled lower edge, and this, in connection with the ta-l pered wall 5e, produces an efiicient suction,

whilethis is maintained and assisted bythe distributer 6, which throws the water outward from the lower end of the leg or tube ping into the channelfat the bottom, it will tend'to be thrown up by the annular curved wall against thebottom ofthe disk 6.

The construction of the suction devlce which I have hereinbefore described I have to being formed by casting in one.integral whole, the only separate parts being the 1 -washer and hose and applicator. Furthermore, my particular construction of Washer not only adapts itself to various sizes of faucets, but also effects secure connection with the faucet, as excessive pressure within the chamber surrounding the conical portion of the faucet only tends to cause the washer to grip the faucet nozzle more tightly.

' Sometimes a faucet may be somewhat irregular in shape with the result that when the washer is applied thereto the water ,will lspurt up between the washer and faucet on account of such irregularity. Thisthe pres-y ence of the lip g l Having thus described my invention what 0 will prevent.

5b against thel wall ofthe shell, whence dropy A suction enerator comprising, a hollow v spreader disk below the lower end of said tube or leg, substantially as described.

In testimony whereof, I affix my signa ture in presence of two witnesses. GEORGE ELMER GRAY.
