HASSAGING MACHINE.

Application filed April 21, 1924. Serial No. 707,986.

This invention relates to improvements in massaging machines.

The main objects of this invention are:

First, to provide an improved massaging machine by the aid of which various parts of the body may be effectively massaged.

Second, to provide an improved massaging machine which may be manipulated by the patient or by an unskilled operator.

Third, to provide an improved massaging machine which is adjustable to meet the particular conditions that it is desired to treat.

Fourth, to provide an improved massaging machine having these several advantages which is very simple and compact in struc-' ture.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a perspective view of our improved massaging machine, the one type of ap licator being shown" by dotted lines.

ig. II is a fragmentary view artially in section, showing structural details Fig. III is a fragmentary view, showing another method 0 improved massaging machine.

Fig. IV is a fragmentary erspective view, further illustrating the met 0d of use.

In the drawing similar reference characters refer to similar parts throughout the several views.

Referring to the drawings, the base 1 is of suitable dimensions and weight to properly support and balance the machine. At one end of this base is an upri ht 2 carrying the forked bearin bracket 3 avi-ng bearin s 4 in the arms t iereof for the shaft 5. his shaft is provided with a pulley 6 disposed between the arms, the pulley being connected by the belt 7 to the ste ped ulley 8 which is in turn connected by t e be t 9 to the pulley of the motor 10. The stepped pull)? 8 provides means for varying the spe of the shaft 5.

Mounted on the shaft is a pair of crank perspective using our crank or wrist discs 11 having radial dove-tailed grooves 12 therein in whlch are adjustably secured the pins 13, the bolts 14 being arranged throug the crank pins with their heads in the rooves. Clamping nuts 15 on the outer en s of the bolts 14 secure them in their adjusted positions.

Stop screws 16 revent the accidental removal of the cran ins. By adjusting the crank pins to and rom the center of the disc, the throw of the crank pins may be varied, as desired. These crank pins are connected by the pitmen or connecting rods 17 to the upper ends of the rocker or swinging arms 18 which are pivoted on the cross arm 19 carried by the upright.

The rocker arms are provided with curved books 20 with which the ends of the straplike applicator 21 may be engaged-either both ends as shown in Figs. I and III, or one end, as may be desired. In Fig. III, I show an applicator 22 narrower than the applicator 21 and having an eye at one end only. Other forms of applicators may be use With the parts thus arran ed, a very great variety of treatments may Tie administered and many portions of the body massaged. and exercised. By varying the speed and adjustin the throw, the treatment is varied or modi ed according to the particular needs or condition of the patient.

We have illustrated our improved inassaging machine in an embodiment which has proven highly satisfactory.

We have not attempted to illustrate or describe certain modifications or ada tations as we believe the disclosure made wi enable those skilled in the art to which our inven tion relates to embod or adapt our improvements as may be desired.

Having thus described our invention,

.what we claim as new and desire to secure by Letters Patent is:

1. In a massaging machine, the combination of a base, an upright mounted thereon and provided with a forked bearing bracket at its upper end, bearings on the arm of said bracket, a shaft mounted in said bearings to roject therefrom and provided with a puley disposed between the arms, crank discs mounted on the ends of said shaft and having radial grooves therein, crank pins adjustabl secured insaid grooves, a cross arm on sai upright, swinging arms pivotally mounted on said cross arms, said rocker arms being provided with curved rearwardly facing hooks, pitmn connecting said crank pins to said swinging arms, and an applicator detachably engageable with said hooks.

2. In a massaging machine, the combination of a base, an upright mounted thereon and provided with a forked bearing bracket at its upper end, hearings on the arms of said bracket, a shaft mounted in said bearings to project therefrom and provided with a pulley disposed between the arms, crank discs mounted on the ends of said shaft and having radial grooves therein, crank pins adjustablysecured in said grooves, a cross arm on said upright, swinging arms pivotally mounted on said cross arms, and pitmen connecting said crank pins to said swinging arms.

3. In a massaging machine, the combination of a base, an upright mounted thereon and provided with a forked bearing bracket at its upper end, hearings on the arms of said bracket, braces extending from said arms to said base, a shaft mounted in said hearings to project therefrom and provided with a pulley disposed between the arms, crank discs mounted on the ends of said shaft and having radial grooves therein, crank pins adjustably secured in said grooves, arms pivotally mounted on said up asa na pivotally mounted on said upright for independent pivotal movement, pitmen connecting said arms to said crank pins, and an applicator adapted to be connected to said arms.

5. In a massaging machine, the combination of a base, an upright, a shaft carried thereby, crank discs on said shaft provided with crank pins, arms pivotally mounted on said upright for independent pivotal movement, pitmen connectin said arms to said crank pins, and an applicator adapted to be connected to said arms.

6. In a massaging machine, the combination of a base, an upright, a shaft carried thereby, crank discs on said shaft provided with radially ad'ustable crank pins, arms pivotally mounte on said upright for independent pivotal movement, and pitm'en connecting said arms to said crank pins.

In Witness whereof we have hereunto set our hands.
