Application iled September` 2l, 1903. Serial NO.1'L,058. (No model.)

To .all whom. it may concern:

Be 'it known that I, CHARLES PEANsci-IMIDT, a citizen of the United States, residing in Chicago, in the county of Cook and State of lllinois, have invented certain new and useful inprovements in Massage-Machines, of which the following is a speciiication.

This invention relates to that class of ma chines employing' a suitable `cup or pad for imparting a vibratory motion to the skin; and the invention more particularly relates tothe means by which said vibra-tory motion is irnparted to the pad or cup and the manner in which the parts are assembled so as to insure uniformity of movement and freedom from undue friction and at the same time combine simplicity and durability.

The invention consists of the features of construction and combination of parts hereinafter described and claimed.

In drawings illustrating the invention, Figure l is a longitudinal sectional view of the operative parts of the invention; Fig. 2, a bottom view of the handle and head, showing some of the parts removed; Fig. 3, a sectional plan View taken on line 3 3 of F ig. l; and Fig. 4, a cross-sectional view of the head Aor casing, showing the operative parts therein.

As constructed, the massage-machine of this invention consists of a handle A, preferably constructed of wood, libel', or other suitable material and provided in its interior with a longitudinally-extending hole a, provided with suitable bushings a', and within the hole is a rigid shaft B, provided on its outer end with a iiexible shaft I), leading to an electric motor or other suitable source of energy. (Not shown.) The shaft at its opposite end is provided with a cylindrical head C, within which is a spiral groove c, forming a spiral cani havingl inner contact-faces c. The head C is inclosed within acasingD, terminating in a neck d, which is secured within the handle by means of screws el' or otherwise. The head or ease is provided on its forward end with a projecting portion D', on the flat face of which is a recess cl2, within which is secured a plate E, which plate is likewise secured to the neck CZ by means of screws e or otherwise, thus inclosing the spiral earn within the `head or case.

The fiat plate E is provided with a longitudinally-extending slot e and with outwardlyprojecting beveled guid e-walls e2. `(Best shown in Figs. 3 and 4.) Mounted within the flat plate between the guide-walls isa reciprocating plate F, terminating in -a piston rod or steinf, proj ecting back inte the handle, andthe reciprocating plate has its outer edges beveled.

as shown in Fig. 3, to conform to the beveled inner faces of the guide-walls, allowing the reciprocating plate to travel back `and forth between the guide-walls and preventing its withdrawal therefrom.

In order to prevent undue friction, it isudesirable to construct the reciprocatingplate, as shown in Fig. fi, to have a recessed inner face e, with contacting' flanges e" around its edges, and to `make the plate of a thickness to leave a space er between it and the outer edges of the beveled guide-walls of the hat plate.

Upon the reciprocating plate is mounted a roller G, journaled upon a pin g and adapted to rotate when brought into contact with the contacting inner faces of the spiral calm, and said roller is constructed of a diameter to ahllow it to contact but one of the faces .of the spiral cani, so that on the forward thrust of the plate the roller will be contacted by one of the faces and on the rear thrust of the cam by the other face, allowing its partial revolu- 30 tion first in one direction and then in the opposite direction, depending upon the forward or backward thrust of the reciprocating plate. This arrangement prevents the parts from being unduly heated by friction during the operation of the machine.

The cani-head is journaled at its forward end by a screw-threaded cone hearing-pin H, provided with a 'lock-nut 71., which arrange nient enables the parts to be adjusted to meet the requirements of use.

Outwardly projecting from the reciprocating plate and at right angles thereto is a shaft I, which is screw-threaded into the plate, and on the end of the shaft there is secured a suitable massage member t'. "Within the recip to open-through vthe piston-head within a cylinder Zr, located within the handle of the machine and provided with an outwardly-opening valve 7c of any suitable construction, which arrangement permits a 'discharge of air through the valve on the backward thrust of the piston and prevents its admission on the4 forward thrust of the piston, thereby creating a suction up,through the airpassages and within the hollow massage-cup, as shown in Fig. 1.

In orderto provide for a variety of movements, a longitudinally-extending recess L is cut in the outwardly-projecting portion of the head or case, and within said recess is located areciprocating shaft Z, having attached thereto a massage member, and between the iiat reciprocating plate and the yreciprocating shaft is located a spring Z', which is normally heldin no tension, but which when the reciprocating' shaft is inwardly pressed will establish communication between the reciprocating shaft and the reciprocating plate and impart a vibratory'motion to the massage member, and the strength of the motion will .depend entirely upon the amount of pressure exerted against the massage member from without, which pressure serves to bring the parts more closely into contact with one another.

The parts are inclose'd by means of an eX- terior cap or plate M, provided with side walls m and end wall m', Vthrough which walls pass screws m2, uniting the exterior cap or plate to the casing. The casingis provided with a longitudinally-eXtending slot m3, through which projects the shaft I, and with a hole mi, through which projects the shaft Z.

The operation of the device will be partially understood from the foregoing description, but may be briefly stated as follows: When rotation is applied to the fixed shaft, the spiral cam-head will be rotated and the cam-faces alternately brought to bear against the roller G, forcing the reciprocating plate back and forth along a line of travel parallel to the handle, thereby imparting a sidewise travel to the massage member, causing a rubbing or kneading operation to be transmitted to the portion of the body acted upon. The edge of the massage-cup will be closely pressed against the skin, and upon the inward thrust of the reciprocating plate the valves Z0', will be closed, and a suction from the interior of the massage-cup will be induced to ill the vacuum within the cylinder caused by the backward thrust of the piston-head therein and by the closing of the valve against the admission of air from withoutm This suction will tend to draw the blood to the skin, and at the same time the edges of the massage member rubbing over the skin will produce a kneading or frictional effect thereon, which will be found highly advantageous in the treatment of the skin and scalp, and at the same time the vibratory motion will be suiiiciently strong to affect portions of the body away from the immediate vicinity of the part acted upon. The amount of sidewise travel of the massage member can be regulated by changing the degree of spirality of the groove within the cam-head, and the amount of suction. produced can be varied by increasing or decreasing the size of the cylinder and pistonhead employed; but such changes do not in any way affect the character of the invention.

When the reciprocating shaft Z is not employed, it can be removed from the massagemachine and not interfere in any way withl the operation of the other parts, or the machine can be constructed without any such shaft without changing the operation in any way. Although the invention has been described with considerable minuteness as to mechanical details and features, it is plain that the same can be varied considerably and that the parts can be assembled and inclosed in a somewhat different manner without in any way departing from the spirit of the inventiou.

What I regard as new, and desire to secure by Letters Patent, is-
