Patented Jug e 10, 1930 PATENT OFFICE ABRAHAM W. LAIR, 01' LOS ANGELES, CALIFORNIA MASSAGE MACHINE Application filed January 28, 1927. Serial No. 164,288.

My invention relates to massage machines, and the objects are first, to produce a mechanism whereby all the varied physiological effects for massage are obtained by alternate "condensation and rarefaction of air within a cup placed adjacent the human body, the therapeutic value of which lies in the facts that by such mechanical action the circu1a-.

tion' of blood is enhanced and stagnation is overcome, capillary stasisis freed and excessive labor is removed from the heart, the limphatic glands and vessels are also stimulated to better actionthus causing broken down cells and waste matter to be removed from the blood plasma, hence the blood ispurified, and in turn the nervous system receives blood of a better quality and is brought into a normal and healthy activity; second, to produce a mechanism that relieves inflammation and promotes theabsorption 39 for exercising or massaging pneumatically the tympanum in the treatment of certain diseases and abnormal conditions of the ear.

A further object of the invention is to provide a simple, durable and efficient device for the accomplishment of the above mentioned purposes, as well as other purposes which will become apparent from a perusal of the following specification, and an examination of the accompanying drawings, in which:

My invention comprises acabinet 1, in which is placed amotor 2 mounted upon asuitable base 3, thebase 3 is in turn slidably held in position in theguides 4, and adjustably clamped into position by thescrews 5. Themotor 2 being connected to ashaft 6 withpulleys 7 and 8 mounted on theshaft 6, andmotor 2, respectively. Theshaft 6 is journaled inbearings 9 and supports acrank 10 on the outer end thereof, twolugs 11 are in turn formed opposite one another on the center line of thecrank 10, two slides 12 are secured between thelugs 11, spaced equidistant from the said center line of thecrank 10, and ascrew 13 is turnably mounted on the center line of thecrank 10, in thelugs 11. Ablock 14 is slidably mounted upon the slides 12, and a-djustably supported by thescrew 13. The center of the outer end of theblock 14 is formed with apin 15, and one end of a connectingrod 16 is operatively secured thereon.

A pump 17 is secured in thecabinet 1 with relation to the saidcrank 10 havingpump heads 23 secured in both ends of the barrel thereof, and a shaft 18 passes slidably through the longitudinal center of the pump barrel withinbearings 19, and thepump heads 23 are secured in both ends of the barrel of said pump 17. Apiston 20 is slidably secured on the shaft 18 in the said pump, one end of said shaft 18 being formedbers 24 are eratively' ositionedover said with a-joint 21, and the joint 21 is in turn connected to'the connectirod 16. v

Thepumphead 23 is ormed with twovalves 22, one being positioned at each end thereof, as shown in Figure 7. Slidemem valves 22, an are opene and closed by links 25, the links 25 being operated. by thelevers 26. Thelevers 26 are adjustably mounted on thefulcrum members 27, and the lugs 28- are formed on the outer ends thereof with relation to graduatedslots 29 in aplate 30,

theplate 30 being secured upon a support in saidcabinet 1. Thevalves 31 are also positioned in the two ends ofthepump heads 23, as shown in Figure 7 and the flapper 'members32 are hingedly secured to the saidheads 23. Theshafts 33 are operatively' mounted inbearings 35, saidbearings being formed on theheads 23, and thecams 34 are in turn formed on the lower ends of saidshafts 33, andlevers 36 are securedto the upper ends thereof.Plates 37 witharcuate flanges 40 formed about center of theshafts 33 are secured to the cabinet'l with relation to saidlevers 36, graduatednotches 39 being.

formed in the'outerarcuate flange 46, and

' -lugs 38 are in tu;rn,formed on the saidlevers 36 to engagewithsaid notches 39. A The ada ter. 41 comprises abore 42 in which is shdably mounted a sleeve 43,anda head 44 is in turn permanently secured'in the sleeve 43, thescrew 45 being arranged to clamp said sleeve. 43 stationary within saidbore 42 when desired; j

.Theheads 57 aresecured in both ends of thebore 42 and thescrews 53 and 54 are inheads 57, with the said head' 44. open into sleeve 43. Oil cups are secured in the vaccumulating in thepassage 52 may 48 and 49. The sleeve 43 is formed withports 46 and 47 spaced from one another to alternately open and close theports 48 and .49 respectively, as the said sleeve 43 and-head 44 reciprocate back and forth between thebumpers 58 and 59, with a predetermined stroke, depending upon the position of the said screws -53-54 and.head 44 within the upper portion of theadapter 41 to su ply oil to the bearing surface between the box-e42 and sleeve 43 and the overflow oil therefrom be drainedthrough apetcock 56 positioned in the bottom wall thereof.

The pipes '68 and 69 are connected between I the chambers 70 and 71 respectively,-in the pump 17, and thepassages 51 and 50 respectlvely, 1n theadapter 41,connectors 72 and 73 are. formedinthe passage 52 andpipe 69 block,14 on respectively, to detachablyhold ahose 60, theoplposite. end of the hose .60 being secured to a'ousin 62 andcup 61, the'housing being rovirfed withflapper valves 63 an 64, an control arms '65 and 66 respectively. Before operating my invention the positionof themotor 2 is adjusted tore ate the-distance between thepulleys 7 an 8 to give a tight gripping .or loose slidingbelt connection 74, by sliding thebase 3 1n the guides and clamping thescrews 5 in osi- 1n 1.77 will, read .w ere required on thesca e 76. The stroke of the tions so that the connectingrod 16 is adjusted by'setting' the dead center of thecrank 10, to read where required on thescale 7 5',by turning thescrew 13,-thus determining the length of the strokes of theiston 20 in the pum openings int e valves 22 are placing the slide members 24'thereover, by

the slides 12 a distance from the f 17. The usted by placing the lugs '28 in the requiredslots 29 thus holding the connectinglevers 26 andlinks 25 in stationary positions.

The openings in thevalves 31 areadju'sted to open and close alternately by theflappers 32, said flappers being controlled as required by thecams 34 which are swung about on the center'of the shafts'33 with relation to the .2

position of the 'levers' 36, thelugs 38 being set into the adjacent graduatednotch 39.

When thetwo valves at each end of the ump 17 are both adjusted to maintain them' 1n the closed position and'the adapter sleeve 43 is held stationa by therods 53 and 54 (Figure '5) being a justed to hold theheads 58 and 59 againstopposite sides ofhead 44,

then an ual and too forcible puflr and suction will bodyby the applicator on 61. The various adjustments ofvalves-an of the length of the stroke of theadapter head 44 are provided to soften such action and to regulate e applied to the surface of the.

amount of puif as compared-with suction.

The valves at each end'of ump 17 will, in-

proportion to the extent w 'ic'h they'permit air to enter and to leave the pum weaken the reciprocatory force applie to v the adapter, but if'these valves are symmetricall adjusted, pufl and suction willbe equal.

he position and stroke of the sleeve in thebore 42 is adjusted where required by first clamping the said sleeve 43 to read on the .scale'78, and then adjusting the screw ends 58 and 59 to predetermined distances from the center of said bore 42 to control the open ings between the ports 47-49 and 46 -48.

. he operation will be more readily understood if it is borne in'mind that theelectric motor 2 is operatively connected with thepump piston 20 in suchamanner as to recip- 'rocate said pistonquite rapidly, and the cross-sectional'area of the piston cylinder 17 1s more than twice that of the space inclosed by the sleeve 43 of the'adapter, thus providing for transmission to said sleeve'43 of about double the amount ofmovement for each reciprocation which is being iven at any time to thepiston 20, provi ing thevalve closures 24 of thepump cylinder heads 23 are adjusted to the completely closed position. That is to say, while the pump piston moves one inch the sleeve of the adapter will move about two inches. The extent to which theflapper valves 31 open may also be regulated as desired, but the opening of thevalves 31 does not interfere with movement, by suction, being transmitted from the piston cylinder 17 to the sleeve 43. There is continuous communication (see Figures 5, 6 and 7) betweenchambers 50 and 71 and between chambers 51 and 70 hence, since thepump piston 20 reciprocates rapidly and as the area thereof is more than twice the area inclosed by the sleeve 43, considerable leakage may be permitted thru the valve openings '22 without rendering ineffective the action of the sleeve 43 in transmitting the desired variations of atmospheric pressure to theapplicator cup 61.

With the several adjustments made as to the position of themotor 2, crank 10,valves 22,valves 31,head 44 and bumper ends 5859, power is transmitted from themotor 2 through the pulley 8,belt 74,pulley 7,shaft 6 and crank 10 respectively. The turning movement of thecrank 10 forces thepiston 20 in the pump 17 to reciprocate through the shaft 18, and the connectingrod 16 connected thereto.

Pipe 68 leads to cylinder chamber 70 at the right ofpiston head 20 as viewed in Figures 1, 2-and 6, andpipe 69 leads to the other cylinder chamber 71. Now when piston rod 18 moves to the left (cams 34 holding closedflappers 32, both ends of cylinder) the air is sucked from chamber 51, Figure 5,

and the suction draws sleeve 43 toward the left end ofchamber 42, untilpartition 44 strikes the bumper 59. At the same time this suction action is taking place in the right end of the cylinder 17 and left end of the adapter there is also a compression action in the left end of said cylinder and right end of the adapter as follows:Piston head 20 moving to the left creates a pressure in chamber 71 of pump cylinder 17. This pressure is conducted throughpipe 69 tochamber 50, from where it forces sleeve 43 toward the left. Hence on one side ofpartition 44 there is suction isochronously with a compression on the other side, thus operating the sleeve.

Thehousing 62 is provided to afford a means whereby, without changing the action of the machine, a continuous suction, a continuous blowing or an alternating suction and blowing effect may be obtained merely by operating the valves. 63--64 by the. controls 6566 respectively with thecup 61 on the body. The mode of pneumatic delivery machine in general. The valves can also be permanently set in theadapter 41 forany mode of pneumatic delivery when using varioussized cups 61.

The stroke of thecrank 10 is lengthened or shortened when changing from asmall cup 61 to alarger cup 61, to provide the necessary pneumatic volume.
