Arnold, 3324 75th St., Jackson Heights, N.Y. Filed Dec. 19, 1951's. No. 703,772 8 Claims. 01. 128-57) This invention relates to an improved barrel roller massage machine.

An object of the invention is to provide a barrel roller which is simple and inexpensive to manufacture and very easy to assemble.

Another object is to provide such a machine which is convenient to use and which can easily be adjusted as desired to obtain best efficiency and speed of operation.

These and other objects will in part be understood from and in part pointed out in the description given hereinafter.

A machine known in the trade as a barrel roller, which is used for body massage, has a horizontally mounted drum or barrel that carries around its periphery a multiplicity of long thin fluted rollers parallel to the axis of the drum and individually free to rotate. When the machine is in operation, the drum is rotated at a moderate speed while a person holds some portion of his body against the periphery of the drum, the ridges and grooves in the individual rollers as they revolve serving to massage the body.

In the past, barrel rollers were relatively expensive and they were difiicult and tedious to assemble because of the great number of parts which had to be carefully fitted together. The structure of these parts was such that the barrel, with its associated rollers, had to be assembled first, and then the supporting frame in which it is mounted built up around it. After the unit was assembled, this in itself often requiring half a day, the frame could then be finally painted. However, since it is undesirable that the rollers and certain other moving parts be painted it was further necessary during painting to go to great lengths to mask these parts. As a consequence, not only was assembly difficult, but painting was perhaps more so. i

The present invention overcomes these difiiculties by providing a barrel roller in which barrel and frame can be assembled separately, painted, and then put together as a complete unit. The structure of the barrel and its individual rollers 'is-considerably simplified by providing two thin flat rigid metal discs between which the individual rollers are supported. These discs in turn on their outer faces carry bosses or pins which engage with the spokes of belt-driven pulleys, the pulleys being of a kind commercially available at low cost, Pulleys and discs are then rotatably mounted on a uniform-diameter axle supported at'its ends between two upright plates of a stationary frame. To assemble the barrel sub-unit in the frame, this axle is simply passed through the center holes in the discs and pulleys of the barrel and the end plates of the frame, and then secured in place by cap screws. The entire operation can be completed in a few minutes. Lateral play of the barrel within the frame is easily elim inated by tightening the cap screws on the axle, and this feature permits a user of the machine throughout its life to keep it in perfect adjustment.

The barrel is rdtated within the frame by belts engaged over the drive pulleys carried on its two end discs, the

discs 20. The pinshave heads countersunk into the discs 2,939,455 7 Patented June 7, 1 960 2 belts in turn being driven from an idler shaft which is belt-driven from a small motor. This motor is adjustably mounted on the stationary frame and has an expandable drive pulley so that by externally varying .the position of the motor, the rotational speed of the barrel can be controlled. This constitutes a very simple and inexpensive arrangement.

-A better understanding, of the invention together with a fuller appreciation of its many advantages will best be gained from the following description given 'in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of a barrel roller embodying features of the invention;

Figure 2' is an enlarged cross section view taken as indicated by lines 2-2 in Figure 1;

Figure 3 is a longitudinal section view taken as illustrated by lines '33 in Figure 2;

Figure 4 is a greatly enlarged view of one end of the barrel showing the manner of attachment of an individual roller; and

Figure 5 is a section view of the motor pulley.

The barrel roller 10 seen in Figure l includes'a stationary frame 12 having two vertical end plates 14 between which is rotatably mounted the barrel '16. The barrel is cylindrical and it carries around its rim a multiplicity of the individual rollers 18, each roller being fluted along its length and rotatablymounted on the barrel. When the barrel rotates, these rollers can rollin contact with a persons body and massage it.

As seen in Figures 2 and 3, rollers 18 are mounted between the two thin end discs 20, of a suitable material such'as cast aluminum, the rollers being supported at theirends by the pins 22. Each pin as seen in Figure 4 is firmly driveninto an end bushing'24 in its respective roller and the pins and bushings rotate relative to the and they pass through oversize'holes in the discsi-nto bushings 24, the bushing providing endbearings for the rollers. To preventskewing of the rollers, discs 20 as seen in Figures 2 and 3 are tied together by three equally spaced rods or-bolts 26 whose ends pass through the discs and are capped by nuts, which allow adjustment to be made on the barrel or drum section to compensate forwear.

Each disc 20 on its outer face has the four integral bosses or shoulders 28, which, as seen best in Figure 2, nest against the spokes of respective ones of the pulleys or sheaves 30. Bosses 28 radially position a pulley on its disc and provide rotation of the two in unison, they are anext'remely simple yet effective means of attachment It will be noted in Figure 4 that the outer rim of pulley 30' partly covers the heads of pins 22 and thus positively prevents any fromfalling out in the event that it works loose in its bushing 24.

Frame 12 includes vertical end'plates 14, previously mentioned, which are held together by the horizontal side braces 32 and 34 bolted, screwed, or welded between these To assemble barrel 16 within the frame, the

plates. barrel and sub-assembly including pulleys 30 is lowered into place as indicated in Figure 3 between plates 14 and then. a straighter. uniform diameter central axle 36 is passed through these members and secured in place by the end cap nuts 38. If desired, a washer 40 can be inserted between each pulley 30 and plate 14 to reduce lateral friction. By tightening nut 38, the compressive force against discs 20 can be increased to compensate for any looseness which may develop in rollers 18 this force acting equally on all the rollers and uniformly controlling their tightness.

Barrel 16 is rotated within frame 12 by the endless belts 42 engaged on respective ones of pulleys 30 and also passing around the idler pulleys 44 carried on a shaft 46. This shaft as seen in Figures 2 and 3 is journaled in the end blocks 48, each of which is carried on a respective one of plates 14 and can be rotated about its eccentric mounting pin 50 to. adjust the tension on belts 42. Blocks can bev adjustably locked in angular position by the bolt and slot arrangement 52..

Also carried on shaft 46 is a third pulley 54 around which is looped a short belt 56, the other end of which passes around an adjustable pulley 58 carried on the shaft of the motor 60. This motor is mounted on a plate 62 hinged at 64 to brace 34 and is adjustable toward or away from the brace by means of thescrew and knob member 66.

When the motor is moved all the way against brace 34, the tension on belt 56 will decrease the efiective diameter of the motor pulley, shown also in Figure 5, by forcing its spring loaded half 68 to the right. This causes the roller to nm at minimum speed. Conversely, by moving motor 60 -to its maxi-mum limit away from brace 34, the barrel will run at speed.

Plates 14 can be identical to each other andare advantageously cast aluminum. Similarly, discs are identical, as are pulleys 30. Thus these parts can be obtained at less cost and can be assembled without regard .to right or left. The barrel roller as shown in Figures 2 and 3 is drawn to scale; the diameter of pulleys 30 in a full size unit is 12 inches. Because these pulleys are very thin, the gaps between the ends or rollers 18 and the support plates 14 are of minimum size. The weight of a machine constructed according to the invention is substantially less than that of previous machines but yet the present machine is stronger and more rigid by virtue of the metal castings.

The above description of the invention is intended in illustration and not in limitation thereof. Various changes may occur to those skilled in the art and these may be made without departing from the spirit or scope of the invention as set forth.
