I Specihcatlon of Letters iatent. I Patented J 4, 1911- Application fled April 0, 1911." Serial No. 619,335. I

Toall whom it may concemi Be it known. that I,'RAYM0ND W. Gun.

FITH, a citizen of the United States, and'resi dent of Milwaukee, in the county .of Milwaukee and State of Wisconsin, have in vented certain new .and useful Improvements in Massaging Implementsf'and I do gage by'screws 7 t hereby declare that the following'is a full,

clear, and exact description thereof.

M 1nvent1on consists in what is herein particularly set forth with referenceto the accompanying drawingsvand pointedout in the claims of this specification, its object be-! ing .to provide simple, economical and eflicient. vacuum vibrator' massaging imple ments especially designed for the use of suction cup applicators, provision being had for regulating the strength of'the'vibrations and the intensity of the vacuum in .s aid applicators. 1

Figural of the drawings represents a central ongitudinal section viewof pne of. my improved vacuum v1brators having a suction-cup applicator therewith, and Fig. 2, a 25 by line 22 in.-Fig. 1. I p Referring by numerals to the drawings, 3

transverse section of the vibrator indicated indicates a casing that is preferably employed to inclose a cylinder 4, a head 5 of. the e linder being provided with lugs 6 'enat extend through apextures in said casing adjacent to an end of the The head 5 is shouldered and the same. inner shank portion thereof has screw-thread engagement with the wall of the cylinder, whereby separation of said head from said cylinder. may be readily effected whenever necessary or desirable. central outer boss 5' of the cylinder head is lon itudinally recessed to provide a socket wit which thengage the shank of any suitable formof up plicator. The suctionvcup applicator 8 herein shown'has its shank in the iormofa hollow serew-9 for which the socket aforesaid is 'suitabl threaded, and 'a'washer 10 is in-. terp'osed et'weenpthe cup and. the head of the screw. The cylinder has'its wall provided with a'longitudinal air-inlet passage 11 controlled bya screw-valve 12 engaging a portb oss 13 of said cylinder in communication withsaidpassage, the screw being tapcr slabbed upon one or. both sides thereof to'provi'd fora finely regulated area -,of

{air "opening according to the adjustment of said screw. The air-inlet passage aforesald is provided with ports 14, 15 to the -bore of the cylinder equidistant from an exhaust port 16 of said cylinder. Theexhaust-port 'leadsinto an air-outlet passage 17 in the'cylinder-wall lon itudinally oft-he same, and a port 18 leads om the cylinderhcad socket above specified into said airoutlet passage, s nction in the cup-applicator being controlled by a screw-Va vs 19 similar to the'one 12 aforesaid and adjustable in a 'port;boss' 20 of the cylinder-head 5. Both of the aforesaid screw-valves extend through v the casing 3 to be convenient to the operator of the herein described vibrator, and a regulator valve in the form of aslabbedand pointed screw-plug 21 is engaged 'with a threaded enlargement of said passage back of the valve 19, the regulator valve 21 being permanently set in proportion to the normal pressure desirable in the cylinder. The-air-- outlet passage is continued through arear head shank 22 of the cylinder, and a flexible 'tube 23 1s made fast at one end on said shank, its other end being suitably connected to a suction generator not shown but common n the artto which my 1nvent10n' relates, said tube being run through an opening in'the aforesaid casing.

A floating piston 24 of suitable wei ht occupies the cylinder 4: and is provide with central longitudinal passages 25, 26 that re-.

spectively lntersect transverse passages 27,

28'that lead to outer annular grooves 29, 30 I of said piston, these grooves being alternately in register with'the exhaust port 16- of said cylinder.

In the operation of myvacuumvibrator, 3

air is e'xhausted from one end of the cylinv der 4- through thelongitudinal. and trans verse passages of the piston 24 then in communication with the exhaust-port 16 of said cylinder, while at the same time air is admitted. to the other 'end of the said cylinder through ,the-Zother longitudinal and transversepassages of said piston then in communieation with a port of the air-inlet passage 111 The result is a rapid movement of the piston tosthe' vacuum end-of the cylinder and an immediate reverse movement of said piston takes place. "The automatic rapid reciprocation of the-piston effects the vibrations desired, and the velocity and consequ'ent strength of these vibrations is regu lated by an adjustment of the valve 12 that controls the air-inletpassage 11 of the aforesaid cylinder.

I claim: 1. In a vibrator massaging implement, the combinationgof a. cylinder the wall of which" is provided with-independentair-inlet and -airoutlet passages longitudinally thereof communicating through ports with the cylinder-bore, a floating piston in the cylinder provided with passages through which air is simultaneously admitted to and exhausted from opposite ends of said cylinder, a control-valve, for each of said passages, the outlet passage being for communlcatlon with g a vacuumxgenerator, and an applicator in connection with a head of the cylinder.

2. In a vibrator massaging implement, the combination of a cylinder the wall of-fwhich isprovided with independent air-inlet and air outlet 'passagefs'j'longitudinally "thereof communicating through ports with the cylinder-bore, a floaJLing pistonin' thcoylindcr provided withpassages through which air is simultaneously admitted to and exhaustedfrom opposite ends of said cylinder, a screwvalve arranged to control the air-inlet .pas

pconibinatio'n of a cylinder the wall o fwhi'ch is provided withindependent air-inltang'l airoutlet passages longitudinally thereof communicating through ports with thc'cyl inder-bore a cup-applicator having a liollow shank engaging a cylinder head socket in. port communieationwvith. the air-outlet passage, a valve arranged to regulate suction in the' applicator, a floating piston in the cylinder provided with passages through which air is simultaneous] y admitted to and exhausted from oppositecnds of saidcylini der,'a control valve for each of saidpassages, the outlet passage being for communication with a vacuum generator, and an applicator in connection with a head of the cylinder. v 1

4. In a vibrator massaging implement, the combination of a casing, a cylinder supported-in the casing and provided in its all with independent air-inlet and aif-outlet passages longitudinally thereof commu- 'nicating with the cylinder-bore, a floating piston in the cylinder provided with passagesvthrough which air is simultaneously admitted to and exhausted from opposite ends of said cylinder, a control valve' for. each of said passages, a flexible tubing socured in connectionwith a shank of the cylinder through which said outlet passage is extended, the tube being extended through the'casing for connection with a vacuum generator, and an gapplicatoriir-connect-io 7 with the outer-head, of the cyfli'nderf 5.
