MASSAGE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 702,820, dated June 17, 1902.

Application iiled November 25,1901. Serial No. 83,550. (No model.)

To all whom, t 11u02/ concern:

Be it known that we, CHARLEs PFAN- SCHMIDT and JOHN SIEFERT, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Massage-Machine, of which the following is a full, clear, and exact description.

Our invention relates to a massage-machine for the use of barbers, physicians, nurses, and others suitable for general use and also for special use upon the face and scalp.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed-out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section of our device, showing certain details in elevation. Fig. 2 is a section showing theprincipal parts of the operating mechanism. Fig. 3 is a fragmentary plan viewwith the cap removed, and Fig. 4 is a detail view of one form of massagecup.

An L-shaped frame is provided, consisting of members 1 and 2, secured rigidly together. A handle 3 is loosely mounted upon the cylindrical member 2. A revoluble shaft 4 is mounted in this cylindrical member and is detachably secured to the end o f a flexible shaft 5. A cam 6, provided with a spiral groove 7, is secured upon the shaft 4 by means of an adjustable nut 8 and is supported at one end by an adjustable screw 9, which is in alinement with the axis of the shaft.

Upon a pivot 10 is mounted a lever 11, so that the lever is free to rock. The upper end of the lever is provided with a yoke 12, in which is adj ustably mounted a boss 13, which engages the yoke by means of screw-threads 14 on the boss. The upper end of the boss 13 is normally free to travel in a slot 16 in a plate 17, which is detachably held in position by means of studs 19 on the member 1 of the frame and which engage recesses 1S in the plate. A revoluble roller 15 is mounted upon the lower end of the boss 13 for the purpose of engaging the spiral groove 7 in the cam 6.

A cap 17a protects the Working parts from dust. The revolution of the shaft t causes the rotation of the cam 6, and thereby rocks the lever 1l. By adjusting the boss 13 relatively to the yoke 12 the roller 15 is made to approach or recede from the axis of the cam, and thereby acts to shorten or lengthen the stroke of the lever 1l.

Upon the lowerend of the lever l1 massagecups 20, 25, and 26 of various forms may be secured. These cups may be provided with plain edges 27 or with serrated edges 28, as desired. The cups are mounted upon a stem 29, provided with a conical upper end 32 and with a threaded cap 3l, which engages the lever 11. A iianged cap 21 and a nut 23 are placed opposite each other upon the respective inside and outside portions of the cup, and a collar 22 bears upon the cap 21, as shown more particularly in Fig. 2.

The upper end of the lever 11 is provided with a receptacle 33 for the purpose of holding oil or any suitable lubricant. An absorbent member or Wick 30 normally depends into the oil and projects upward, so as to make a contact with the groove 7 of the cam 6. The object of this arrangement is to keep the groove of the cam properly lubricated and in doing this to utilize the motion of the lever 11. It will be understood that when the lever 1l rocks the shaking of the receptacle causes the oil to permeate the wick more readily.

The mode of using our invention is quite simple. The operative merely grasps the handle 3, starts up the power actuating the ilexible shaft 5, and passes the massage-cup over the face or scalp of the patient. The massagecup swings in an aro substantially parallel to the general direction of the handle.

We have found that the machine in operation runs smoothly and safely Without any appreciable jar and that its eect upon the person operated upon is very agreeable.

Having thus described ourI invention, Wc claim as new and desire to secure by Letters Patent- 1. Amassage-machine,comprisingaframe, a massage member, a longitudinal handle mounted upon said frame, and mechanism connected with said frame and said massage member, and free to actuate said member in a direction substantially parallel to the general direction of said handle.

2. A massage-machine, comprising a frame provided with a longitudinal head, a handle loosely connected with said frame and disposed at right angles to said head, a revoluble member extending through said handle and provided with a cam, the axis of said cam being at right angles to the general direction of said head and parallel with said handle, a rocking lever pivotally mounted in said head and provided with a member engaging said cam, and means for securing a massage member to said lever.

3. A massage-machine, comprising a frame, a revoluble member mounted thereon and provided with a spiral cam, alever provided with a yoke embracing said cam, a boss mounted upon said yoke and engaging said cam, means for secu ring a massage member to said lever, and means for actuating said revoluble member.

Ll. A massage-machine, comprising ahollow frame, a rocking lever journaled within the same and provided with a receptacle for the purpose of holding a lubricant, a cam for actuating said lever, and an absorbent member engaging said receptacle and said cam for the purpose of lubricating said cam, means for securing a massage member to said lever, and mechanism for actuating said cam.

5. A massage-machine, comprisinga hollow frame havingtwolongitudinalmembers forming an angle with each other, a longitudinal handle mounted upon one of said members,

a longitudinal rocking lever journaled in the other member and normally disposed in a general direction parallel therewith, said lever being free to rock in a plane parallel with the axis of said handle, fastenings for securing a massage member to said lever, and means for actuating said lever, the arrangement being such that said massage member is free to move in a direction substantially parallel with the general direction of said handle.

6. A massage-machine, comprisingahollow frame,a cam mounted thereon, means for actuating said cam, a rocking member provided with a boss for engaging said cam, means for adjusting said boss relatively to said cam for the purpose of regulating the stroke of said rocking member, and means for securing a massage member to said lever.

7. A massage-machine, comprisinga hollow frame, a cam revolubly mounted thereon, means foraetnating said cam, a rocking member provided with a boss for engaging said eam, a guide for preventing said rocking member from moving in a direction other than its normal direction of rocking movement, and means for securing a massage member to said rocking member.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
