MASSAGING DEVICE.

Application led January 17, 1925.

` This invention relates to an improvement in massaging apparatus of the type employing a plurality of rollers which are rotated bodily and which rotate about their own axes, and the object of the invention is to provide a device of this character which may be adjusted to cause the rollers to engage with the flesh to the desired extent and which is effective to increase circulation and to exert a general good effect on the parts of the body on which it is used.

A further object is the provision of an apparatus'of this character wherein the rollers are so constructed as to provide a lingering or kneading action when rolling the iesln A still further object is the provision of an apparatus of this character which is of simple and durable construction, reliable and efficient in operation and simple and inexpensi ve -to manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure l is a perspective View of a preferred embodiment of the invention,

Figure 2 is a view partly in side elevation and partly in longitudinal central vertical section further illustrating the device shown in Figure 1 but showing smooth roliers,

Figure 3 is a view in end elevation leeking to the left of Fig. 2 but showing a differ ent type of roller.

Figure 4; is a view in section ll`4 of Figure 2 I Figure 5 is a detail View in elevation of the referred form of roller., and

Figure 6 is a detail view.

Referring to the drawings, the numeral 1 designates a motor which is supported on and secured to a bracket 2. The bracket 2 is integrally formed with or suitably connected to a cover 3 which has a flange 4 secured by screws 5 to one end of a gear casing 6.

The motor 1 has an armature shaft 7 which extends into the gear casing Gthrough an opening 8 in the cover 3 and the portion of the armature shaft within the gear casing has a pinion 9 fixed thereto. The pinion 9 meshes with an internal ring gear 10 carried on the outer ends of spider arms 11.

en the line .The spider arms 11 are integrally formed Serial No. 3,162.

with a hub l2 which is fitted on and secured to one end of a rotatable shaft 13. Bearings 14 and 15 are provided within the gear easing 6 and in these bearings 14 and 15 the shaft 13 is rotatably mounted.

The shaft 13 projects forwardly from the gear casing 6 and on its forward enda block 17 is threaded. The block 17 may take the forni of a nut and is held in position in any suitable manner. A carrier block 16 is attached to the block 17 by screws 16". A plurality of radially extending studs 18 are carried by the block 16, the studs 18 having threaded portions 19 engaged with internally threaded openings provided in the blocks 16 and held in such openings by set screws 20. The major portions of the studs 18 are smooth and on such smooth ortions rollers 21 are rotatably mounted. earings 22 are provided for each roller, and one end of each bearing engages a head 23 provided on each stud 18. The rollers shown in Fi 2 and 3 have smooth peripheries but t e preferred form of roller is shownin Figures l and 5 and has its periphery serrated or formed with alternate ridges 25 and grooves 26. This serrated or corrugated form of roller exerts a fingering or kneading action on the flesh when the rollers are engaged therewith.

As described and as shown in the drawings the rollers are mounted on that por tion of the shaft 13 which is located outside of the gear casing 6. The gear casing 6 is preferably of c lindrical form and a guard sleeve 30 is sli ably fitted on this gear casing 6. The forward end of the guide sleeve is flared outwardly, as indicated at 31, and is rounded and smooth. Longitudinal slots 32 are provided in the sleeve 31 and through these slots threaded Shanks 33 of set screws 34 extend. The Shanks 33 are threadedly engaged with threaded openings 35 provided in the ge'ar casing 6. Shoulders 36 are forn'ied on the set screws 34 and are engageable with the periphery of the sleeve 30 adjacent the slots 32. The heads of the set screws are flattened out and provided with wings, as indicated at 37, in order to facilitate'manipulation of the set screws. With this arrangement the guard sleeve 3() may be'adjusted to overla the rollers to the extent desired. This eature Ahas the advantage of controlling the degree at which the 1lllolllrs operate upon or contact with the In operation, the rollers are applied to the part of the body to be treated and, as stated, the degree with which the rollers contact is regulated by the guard sleeve 30. The

motor 1 is then started and turns the shaft 13 through its shaft -7 and the gears 9 andk 10. The rotation of the shaft 13 causes the rollers to rotate bodily and the'traction of the rollers on the flesh causes them to rotate on their individual axes. Int-his way motor mounted on the bracket and having its armature shaft projecting into said casing, a' pinion Cn the shaft Within the casing, a shaft mounted in the gear casing, a rin gear carried by the inner end of the sha t and 'i 25 with which the said pinion meshes, a mem- `ber secured to the outer end of said shaft and having a plurality of radial studs, rollers loosely mounted on the studs, a uide sleeve having a flared end and adjusta ly secured to the gear casin and a handle secured to the peripheries o the motor and gear casing.

2. In a massaging apparatus, an openended gear casing, a cover for the inner end of the casing, a bracketprojecting from the cover, an electric motor mounted on the bracket and having its armature shaft projecting into the gear casing through the cover thereof and having a. pinion on its end, a shaft mounted 1n the gear casing, a ring gear with which the pinion meshes,

means for mounting the ring gear on the inner end of the shaft, a pluralityof rollers, and means for mounting the rollers on the outer end of said shaft, whereby they may rotate' bodily and about their own axis.l

3. In a massa-ging ap aratus, a gear casing havingy its outer en open and its inner end closed, an electric motor mounted at the inner end ofthe casing and having its arma- -ture shaft extending into the casin a pinion on said end of the shaft, 'a s aft mounted` in the casing, a spider secured to the inner end ofthe shaft and carryin a ring gear with which the pinion mes es,

and a plurality of rollers mounted on the outer end of the shaft to rotate with the shaft and about vtheir axis.
