Claims. (Cl. 128-57) This invention relates broadly to massaging devices, and in its specific phases to apparatus of the barrel roller type.

Barrel roller type massaging devices are becoming rather popular but insofar as known there are only two forms available. The common one is of the hassock type which is low enough to allow the user to sit upon, straddle or lie, stomach down, across the rotating barrel roller. The other, and little known, is of upright construction with a frame having posts on each side and with the barrel roller adjustable up and down the posts of the frame. The uses of these available devices are rather limited and as far as the adjustable form is concerned, it does not have the versatility and attractiveness desirable for a massaging device of this character. It was a recognition of this situation which led to the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of a novel massaging device in which the driven barrel roller is mounted between the front ends of two side arms which are pivoted to and extend 'fOI".

wardly from the upper end of a stand, said side arms being vertically swingable to different positions to dispose the barrel roller at various elevations to massage any desired posterior or anterior regions while the user is standing more or less upright and to also permit the user to sit upon or straddle the barrel roller when it occupies its lowermost position.

Another object of the invention is the provision of a novel construction permitting pivotal movement of the side arms, and barrel roller mounted on same, to different positions with little effort.

A further object is the provision of a novel brake means for holding the side arms in any selected position, within the operating range of the assembly, to set the barrel roller at desired elevation.

A still further object is the provision of an unusually effective barrel roller which is swingably mounted and in which the individually rotatable peripheral rollers of same are circumferentially corrugated to form them with bulges and with valleys between said bulges, the bulges of each roller being opposite the valleys of adjacent rollers.

Yet another object has been to provide a novel and practical barrel roller construction allowing expeditious manufacture and sale at a reasonable price, yet affording maximum advantages, Whether used for weight reduction, or for alleviating painful physical conditions which can be helped by massaging.

Still further objects and advantages of the invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the massaging apparatus means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but several of various ways in which the principle of the invention may be used.

In the annexed drawings: 7

Figures 1, 2 and 3 are perspective views showing the side arms, and the barrel roller carried by same, adjusted to different positions.

Figure 4 is a fragmentary rear perspective view looking substantially in the direction indicated by the arrow 4 of Figure 2, and with the protective casing removed to expose the driving mechanism.

Figure 5 is a vertical longitudinal sectional view of an alternate construction with the side arms and barrel roller positioned substantially as shown in Figure 1, and with the driving mechanism in reversed position from that shown in Figure 4.

Figure 6 is a fragmentary inner side view of the rear end portion of one of the side arms.

Figure 7 is a horizontal sectional view as taken on line "l7 of Figure 6, looking in the direction of the arrows.

Figure 8 is a fragmentary side view of a portion of the barrel roller illustrating the arrangement of the individual adjacent rollers of same.

The general construction disclosed in the drawings has proven to be commercially acceptable and of advantage from various standpoints and will be rather specifically described. However, it is to be understood that variations may well be made without departing from the spirit and scope of the invention as shown and described.

A stand 10 is provided to support all movable parts. This stand 10 comprises two base bars 11, two standards 12 rising from said base bars 11, two braces 13 for said standards 12, and a tie bar 14 for said base bars 11. All of these elements may be formed from either rod or metal tubing; each base bar 11 is preferably integral with its respective standard 12; and the braces 13 and tie bar 14 are preferably integral.

A transverse shaft 15, Figures 4 and 5, extends horizontallybetween and is welded, or otherwise secured, to the upper ends of the standards 12. The ends 16 of this shaft project laterally outward from the standards and constitute trunnions upon which two side arms 17 are pivotally mounted to swing vertically to different positions. The rear end portions of the side arms 17 are inwardly thickened by plates 18 which are fastened thereto by bolts 19, and bearings 20, Figures 4, 6, and 7, are inset in said plates 18 to receive the trunnions 16. The side arms 17 and their plates 18 can be made from any suitable material, but for convenience may well be sawed from plywood.

A transverse metal frame 21, Figures 4 and 5, extends between the rear end portions of the side arms 17 and comprises two end bars 22 and two

longitudinal bars

23 and 24. The end bars 22 are conventionally fastened as by means of bolts 25 to the plates 18 of the side arms 17; and said side arms are thus connected to swing unitarily upon the trunnions 16. The front ends of the side arms 17 support the barrel roller 26 and this roller is therefore shiftable vertically to difierent positions by swinging said side arms 17 as required. To assure such swinging of the side arms with ease, a counterbalancing spring 27 is provided; and a brake means 28 is employed to lock said side arms in selected position.

The spring 27 is a coiled torsion spring surrounding the fixed shaft 15 and having one of its ends 29 suitably anchored to said shaft, the other end 30 being suitably connected at 31, 32 to the frame bar 23. The member 32 is preferably threaded and adapted to adjust the tension on spring 27 so as to allow the assembly to assume a suitable neutral position when the brake is released, for instance as shown in Figure 1. In the present disclosure, a brake drum 33, forming part of the brake means 28, is secured to the fixed shaft 15 and the spring end 29 is Patented Mar. 28, 1961 I morass? 3 connected at 34, Figure 5, with said drum 33, to thereby anchor said spring end 2% to said shaft 15.

A brake band 35 surrounds the drum 33 and has a conventional lining 36. At one end the brake band 35 terminates'in an arm 37 which is secured at 38 to the frame bars '23 and 24. The'other end of brake band 35 is provided with a nut 39. A hand screw 49 extends through an opening 41 in the arm 37, and the inner end of said screw 40 is threaded through the nut 39. The outer end of the screw 49 has a hand knob 42 provided with a hub 43 abutting the outer side of the arm 37. By turning the knob 42 in one direction, the brake band 35 may be released to allow vertical positional adjustment of the side arms 17 and the barrel roller 25. The side arms 17 may then be locked in the selected position by turning the knob 42 in the other direction.

The driving means for the barrel roller 26 includes an electric motor 44 under the frame 21 and having its base portion secured at 45 to the

bars

23 and 24. This motor is connected by a belt-and-pulley drive as to a countershaft 47 located somewhat in advance of the brake means 23 and having its'ends mounted in bearings 48, Figures 6 and 7, which are inset in the side arms 17. The countershaft' 47 is provided with pulleys 49 connected by belts with pulleys51 on the end disks 52 of the barrel roller 26. The sizes of the various pulleys are of course such as to cause rotary driving of the barrel roller 26 at a suitable massaging speed which is much slower than that of the motor 44.

A suitable casing '53 contains the shafts and 47, the motor 44, the drive 46, the brake means 28, and the counterbalancing spring 27. The casing 53 is secured to edges of the plates 13 and tothe frame 21; and suitable finishing strips 54 may be provided where desired. The casing 53 is slotted at 55, Figure 3, to clear the supporting standards 12 and braces 13.

Suitable guards 56 are provided for the belts 50 and have flanges'57 secured to the longitudinal edges of the side arms 17. Nearthese edges and near the front edges of the side arms 17, suitable hand rails 58 are provided, said rails being carried by brackets 59 secured to the side arms 17.

The barrel roller 26 has a central shaft 60, Figure 5, to which the end disks 52 are suitably secured, for example, by providing said shaft with flanges 61 secured by screws 62 to said end disks. The ends of the shaft are rotatable in bearings 63, the outer ends of which are indicated in Figures 1 to 3.

The individual rollers 64 of 'thebarrel roller 'extend between the end disks 52 and are suitably mounted for free rotation thereon, as indicated by roller pintles 65 in Figure 8. Each roller is circumferentially corrugated to provide it with bulges 66 and with valleys '67 between said bulges es. The bulges of each roller are opposite the valleys of adjacent rollers to more thoroughly massage any portion of the body held against the barrel roller 26.

From the foregoing, it will be seen that a novel and advantageous construction has been disclosed for attaining the desired ends. However, attention is again invited to the possibility of making variations within the spirit and scope of the invention as shown and described.
