UNDULATOR.

Specification of Letters Patent.

Patented May 14, 1912.

Application filed December 7, 1911. Serial No. 664,455.

To all whom it may concern:

Be it known that I, JULIUS A. WARD, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Undulators, of which the following is a specification.

My present invention relates to an improvement in undulating devices, such as is used in movement cure apparatus of a nature similar to that disclosed in my allowed application, Serial No. 645,604, filed August 23, 1911-, with the exception that in the above noted case I have disclosed the pressure means for the said undulators as being comprised of an elastic web attached to the shield or body protecting member. In the present instance the pressure for the said undulators is caused by the use of de tachable weight members mounted thereon.

In the accompanying drawings, Figure 1 is a side elevation of the preferred form of my device with the head member partly in section. Fig. 2 is a side elevation of a modified head member. Fig. 3 is a bottom view of the same.

In Fig. 1 the handle or grip member 5, which may be composed of suitable material such as hard wood or the like, is shown as having at its upper end a shoulder portion 4, said shoulder portion havingproj ecting therefrom a stud or dowel portion 3. A plurality of weights 1, 1, and 2 are detachably mounted upon the upper end of said handle, the said weights being of a suitable metal, such as lead, and being in the form of circular disks having holes therein, the said holes being adapted to closely fit said dowel portion 3. The weights are fitted as above described for the purpose of preventing any shucking or moving of the weights on the said dowel during the use of the massaging device.-

At the lower end of the handle port-ion 5 is attached a convex cup shaped head member 9 which is drawn in section thereby to better show the annular lip portion 10. The shoulder portion 11 having thereon athreaded stud member 8, which adapts the said head portion 9 to be screwed in and out of a suitably threaded bore in the handle member 5. This arrangement permits of the shown head member and the substitution therefor of other modified head members as may be required.

In Fig. 2 is shown a modified form of a head member, being comprised of a substantially semi-spherical portion 7, said head member having attached thereto a threaded stud member 6 which also serves to permit the said head to be detachably re- 1ruoved or aifixed to the handle or grip mem- The herein noted device is used as follows: .A shield, as described in the before mentioned allowed application, is attached to the body, with the patient in a reclining position during treatment, if same be in the abdominal region. The necessary weight members, such as 1, 1 and 2, are mounted together or separately on the grip member accordingly as light or heavy pressure is required. The head member is then placed in contact with the shield and is moved about the body in a substantially vertical position. This method of operation applies to both of the disclosed forms of head members. If, however, a special move ment is desired, this may be obtained by the use of the cup shaped member with sufficient weight thereon. The entire massaging device is then tipped over in an angular fashion until one side of the annular edge 10 comes in contact with the body or shield. The tool is then moved as required, but with a scooping motion, the forwardly moving front edge of the annular member being lifted free of the body and the rear edge being in contact with the same.

The weight members are so arranged that the three said members 1, 1, and 2 are of unlike volumes, thereby affording a variety of combinations when the said weight members are used together or separately, or in combination. For instance, weight number 1 may weigh 111; pounds, weight number 1 may weigh 22; pounds, and weight number 2 may weigh 6 pounds, thereby affording combinations from 1 to 10 pounds.

Having thus described my invention, I claim:

1. An undulator for self massaging in an upright position, comprising a handle member adapted to be grasped by the hand of the user, a flaring shallow cup shaped head of rigid material removably secured in a fixed position at the lower end of the handle to be in close proximity to the hand of the operator, the upper end of the handle having a projecting shank, and a series of superposed disk weights apertured at their centers to loosely fit upon said shank to be readily removed therefrom.

2. An undulator for self massaging in an upright position, comprising a handle member adapted to be grasped by the hand of the user, a massaging head of rigid material removably secured in a fixed position at the lower end of the handle to be in close proximity t0 the hand of the operator, the upper therefrom.
