To lall wiom' concern: l l
Be it known thatl, JULIIUs B. WAN'rz, a
citizen of the United States, residing atChicago, in the county of Cook ,and State oflllinois, have invented a, new and useful- Improvement in Messaging Instruments, of
, which the following is a specification.
My invention relates to an' improvement in the class of. massaging instruments wherein a rapidly-oscillating vibrator is actuated by 'a rotary shaft through the medium of mech-y anism for converting the rotary motion of the shaft into oscillatory massaging motion at the vibrator. v
Y In the accompanying drawings, Figure 1 is a vertical central section of my improved massaging instrument; Fig. 2, a broken sectional view sliowing'the electric switch in its closed condition; Fig. 3, a section taken at the,
line 3 on Fig. 4 and viewed iii the direction -of the arrow, showing themechanisin for converting the rotary motion of the motor-shaft in to the oscillatory motion of the'vjbrator; Fig. 4, a broken section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow, and Fig. 5, a pers active view showing in their unassernbled' re ation the parts of the mechanism .connecting the motor-shaft with the vibrator.
. On a hollow handle 6 at which to hold the instrument for manipulating it, is carried a casing 7, shown in its preferred general globular shape and provided with a tubular exten'- sion 8 at the junction of which with the casing is formeda wall' 9 containing a central shaft-bearing 10. In the casing is suitably su ported an electric motor, of which 11 is vthe field, 12 the armature, 13 the commu- :rftator on the armature-shaft 14 journaled at its'rear end in the casing and at its forward end in the bearing 10', and 15 are the commutator-brushes.
The motor resents no features of novelty, and it is a apted to receive the sup ly of current, as is usual in instruvments o the resent class, throu h a flexible cord "of whicA the current-su py wires 16Y and 17 pass through the hand e 6.
At a neck 18 which extends from' the bottorr. of the metal casing 7 and to which the handle 6, refei'ably oilwood, is connected, is rovide a snap-switch device 19 of the folliiwin -described construction: A rod 20, provide on its ends with knobs, as shown,- extends across the neck 18 preferably in innssaeme rasrnmn'r."
be moved lon 'tudinally, and carrying within the' neck an a utment 21 shown as a roundcured at one end a spring contact-finger 22 provided on its free end with a cam-section 21 an a straight spring contact-iiiigcr 24, insulated'from and extending parallel with the finger 22.
The two contact-fingers are normally se arated, as represented in Fig. 1, to break tige motor-circuit, and to close it the o erator, with `the instrumentl held in his han at the handle, presses his thumb against the knob on the rear end of the rod 20 to force the abutment 21 against the cam 23 and wedge it against the latter, thus into the position re resented in Fig. 2, thereby to contact t e finger 22 with the finger 24, iii which condition the lingers are held by the wedging action ofthe azbutment to close the circuit. vTo open the circuit the operator em loys his forefinger to press against-'the kno on the forward end of the rod, thereby snapping the abutment off thecam23 to permit the finger 22 to separate from the companioniinver.- This construction of switch is very simple and since it permits of easy operation by the same hand that manipulates the instrument.
The vibrator'25 consists of a massagingknob -on 'the end lof 'a stem 26 {'ulcrumednear erein at a rightFangle to the slot 29. As wearon the fulcrum in the oscillatory working, hereinafter described, v of the vibrator y screwing the tapering pin into the stemopening 31 a set-screw 32 serving to releasa ly fasten the pin in its adjusted position. On therear end of the stem, which extends longitudinally through the sleeve, is rovided a head 33 containing in its rear ace a transverse cylindrical recess 34 for reedged disk. On vthewall of the neck are se-V 44'23 pro'ecting into thepathof the abutment.

A knobs,'in the wall o the neck to adapt it t0 cu'liarly desirable inthe particular situation i o p'ening in the sleeve-head 27 which extends t 10oproduces lost motion, the latter is taken up tween its ends with a transverse o ciprocablyconfining a pin 35 provided bev` penlng 36.
l The sleeve 28 fits and isfastened 1n the foi'-v A. vward end ofthe casing-extension 8. On the 'armature-shaft, immediately in advance of the bearing 10, isfsecured to rotate with thel videdl on its periphenwith an index-point 38. 'Adjacent to this wheelis rotatably sup'- portedl onthe shaft a thumb-wheel 39 coptaining a radial slot 40 and provided at su1tableiiltervals about its eriphery with indexcharacters, which may e thenumerals 1 to Y 9, orl a higher number to regi'ster withl the point 38 Vfor the purposehcreinafter explained. The forward end of the shaft 14 enters an eccentric longitudinal' socket 41 in a barrel 42 fixed onv the shaft b asset-screw 43 and provided iiimits forwar end with a series ofradial recesses 44, of which six are shown though they may be in any' desired number and at any suitable' intervals apart f according to the number and de' reespool adjustrnents desired ofthe extent eoscillatory rel 42; 'and it contains in its rear end a hole 48 to receive a pin 49 movably confined nearvits headed end in the slot of the settingwheel 39, a set-screw 5() serving to secure this pin in the hole 48. y
.. justment is attained, in effecting which the Rotation of the shaft 14, with the barrels 42 and 42 thus ec'centrically mounted upon it, causes the stud 45 by its rotation to oscillate the head 33, while reciprocating the pin 35 in the head-opening 34, and this oscilation of the head oscillates the vibrator on the fulcruJn-pin 30 of the stem 26. The extent of oscillation of the vibrator may be adjusted to any desired degree by varying the eccentricities of theebarrels 42 'and 42 relative to the motor-shaft and to each other. This adjustment the operator ma readily effect by holding the vwheel 37 agalnst rotation of the shaft while the adjustment is being made; andturning the wheel 39 to bring a certain character upon its periphery into registration 'with the point 38, according to the degree of'adjustment desired. By thus turning the wheel 39, its connection through the medium of the pin 49 with the barrel 42' turns the latter against the resilient resistance of the bolt 47, which slips over the recessed face of the barrel 42 to engage one of therecesses when the `desired point of adposition of the pill 49 in the wheel-slot 40 will, of course, change. As will be understood, the engagement ofthe spring-bolt Q, y p soupeswith the recesssed face of the inner barrel connects the outer barrel with the armaturep lating the' massaging member the force ofthe Vvibrations does not tend to displace the in- 15.
