Application filed June 6,

My invention relates to a massage machine.

An important object of the invention is to provide a'machine of the above mentioned character, having means for subjecting a portion of the body to the simultaneous action of suction and massaging.

A further object ofthe invention is to proi'ide a machine of the above mentioned character. which is self-contained. simple in construction, and convenient in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a central vertical longitudinal section through a massage machine embodying my invention, i Figure 2 is a side elevation of the-same, and,

Figure 3 is an enlarged detail section taken on line 3-3 of Figure 1.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a casing, as a whole, preferably formed in longitudinal casing sections 6 and 7, which may be united at their adjacent edges, as shown at 8. The casing or housing 5 may preferably be formed of aluminum, although any other suitable material may be employed. Suitably attached to the rear end of the casing or housing 5 is a handle 9, preferably formedof wood or any other suitable material.

ll/founted-within the rear end of the cas- Current is supplied to the motor through a cable 12, extending through a longitudinal opening 13, in the handle 9. The motor 10 embodies the usual armature carried-by an armature shaft 14, and this armature shaft is journaled in bearings-15, 16, 17 and 18,

preferably formed of bronze. The bearings and 18 are carried in the ends of the casing sections 6 and 7. The numerals 19 and 20 designate lubricating ports. The casing sections 6 and 7 are provided with partition sections 21 and 22, which when assembled, form a closed partition, covering port 24.

ing the motor chamber 23. The bearing 16 is held within an opeuing formed in these partition sections 21 and'22 and the partition section 22 is equipped with a lubricat- The casing section 5 is provided in its forward portion with a transverse partition 28, arranged opposite the inner end 24 of a diagonal web 25, providing an air suction or vacuum passage 26,

and a depending mouth 27. "lhe partition 23 has a lubricatin wort 28'. as shown.

lhe partition 23 and the partition sections 21 and 22 provide a fan or vacuum chamber 28. which is circular 11'] cross section and la .charge the air through the ports 29 at the periphery of the fan casing while the inlet passage 26 leads into the fan chamber near the centerof the fan. This fan is the ordinary centrifugal fan, and is of course driven at a high speed by the armature shaft 14.

The web 25 has an opening for receiving a bearing 31, preferably formed of bronze, and this bearing receives the upper end of a vertical. massageshaft 32. Above the web 25, the shaft'32 carries a beveled gear 33, rigidly mounted thereon, engaging a smaller beveled gear 34, rigidly mounted upon the armature shaft 14.

At its lower end, the massage shaft 32 carries a stop element 35, such as'a nut screwed thereon, and'this stop element serves to limit the downward movement of a carriage .36, preferably formed of metal. This carriage,

Figure 3, is provided with a central opening 37, and has inwardly projecting lugs or ribs 38, slidable within longitudinalgrooves 39, formed. in the massage shaft ,32. The carriage is therefore free to-move up and down upon the massage shaft but positively rotates therewith. A suitably light compressible coil spring '40, surrounds the massage shaft 32, and engages the bearing 31 at Its upper end, and rests within a recess 41, at its lower end, which recess is formed within the carriage 36. The numeral 42 designates a massage element, which is suitably yielding or flexible, and is preferably in theformof a hollow rubber ball, which is held upon the carriage 36. Thisrubber ball has a small opening 43 formed in its top, and may be applied to the carriage by stretching the same over thelower end thereof, but will clamp within the groove 44, and thereby rotate with the massage shaft.

' The numeral ,45 designates a vacuum cup, preferably formed of rubber; and receiving therein the massage element or ball 42, which is concentric with relation to the same, and spaced therefrom. The vacuum cup 45 is l suitably secured to the lower end of the lip 27.

In the use of the machine, the same is held by the handle 9,and the vacuum cup is applied to the body, at a desired point, and may be shifted over the same; The portion being treated, is simultaneously acted upon by a the same, and that various changes in the shape, size, and-arrangement of parts'may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims. Having thus described my invention, I claim:

1. In a machine of the character described, a handle, a casing secured to the forward end of the handle and embodying a forward gear chamber and ,a fan chamber arranged at the rear of the gear chamber, a cup connected with the forward portion of the casin and in communication with the fan chain er, a transverse shaft leading into the forward gear chamber, a massage element mounted upon the transverse shaft to rotatetherewith and movable longitudinally thereof, said massage element being located withinsaid cup, a spring surrounding the transverse shaft to force the massage element outwardly, a bevel gear mounted upon the inner end of the transverse shaft and located within the forward gear chamber, a longitudinal shaft extending into the forward gear chamber, a bevel gear mounted upon the longitudinal shaft and in permanent mesh with the first named bevel gear, a rotary fan within the fan chamber and mounted upon the longitudinal shaft, and means to drive the longitudinal shaft.

2: In a machine of the character described,

a handle, a casing secured to the forward end of the handle in end-to-end relation, said casing embodying a rear motor chamber, an intermediate fan I chamber and a forward gear chamber, a cup connected with the for-' forward gear'chamber and connected with the transverse shaft, 1 motor within the rear motor chamber and having an armature shaft extending longitudinally through the casing and through the fan chamber and.

gear chamber, a bevel gear carried by the armature shaft and permanently engaging the first named bevel gear, and the rotary fan within the fan chamber and mountedupon the armature shaft.

In testimony whereof I aflix my signature.

JAMES H. PINKSTON.
