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 the absorption 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 a cabinet 1, in which is placed a motor 2 mounted upon a suitable base 3, the base 3 is in turn slidably held in position in the guides 4, and adjustably clamped into position by the screws 5. The motor 2 being connected to a shaft 6 with pulleys 7 and 8 mounted on the shaft 6, and motor 2, respectively. The shaft 6 is journaled in bearings 9 and supports a crank 10 on the outer end thereof, two lugs 11 are in turn formed opposite one another on the center line of the crank 10, two slides 12 are secured between the lugs 11, spaced equidistant from the said center line of the crank 10, and a screw 13 is turnably mounted on the center line of the crank 10, in the lugs 11. A block 14 is slidably mounted upon the slides 12, and a-djustably supported by the screw 13. The center of the outer end of the block 14 is formed with a pin 15, and one end of a connecting rod 16 is operatively secured thereon.
A pump 17 is secured in the cabinet 1 with relation to the said crank 10 having pump heads 23 secured in both ends of the barrel thereof, and a shaft 18 passes slidably through the longitudinal center of the pump barrel within bearings 19, and the pump heads 23 are secured in both ends of the barrel of said pump 17. A piston 20 is slidably secured on the shaft 18 in the said pump, one end of said shaft 18 being formed bers 24 are eratively' ositionedover said with a-joint 21, and the joint 21 is in turn connected to'the connecti rod 16. v
The pumphead 23 is ormed with two valves 22, one being positioned at each end thereof, as shown in Figure 7. Slide mem valves 22, an are opene and closed by links 25, the links 25 being operated. by the levers 26. The levers 26 are adjustably mounted on the fulcrum members 27, and the lugs 28- are formed on the outer ends thereof with relation to graduated slots 29 in a plate 30,
the plate 30 being secured upon a support in said cabinet 1. The valves 31 are also positioned in the two ends of thepump heads 23, as shown in Figure 7 and the flapper 'members32 are hingedly secured to the said heads 23. The shafts 33 are operatively' mounted in bearings 35, saidbearings being formed on the heads 23, and the cams 34 are in turn formed on the lower ends of said shafts 33, and levers 36 are securedto the upper ends thereof. Plates 37 with arcuate flanges 40 formed about center of the shafts 33 are secured to the cabinet'l with relation to said levers 36, graduated notches 39 being.
formed in the'outer arcuate flange 46, and
' -lugs 38 are in tu;rn,formed on the said levers 36 to engage withsaid notches 39. A The ada ter. 41 comprises a bore 42 in which is shdably mounted a sleeve 43, anda head 44 is in turn permanently secured'in the sleeve 43, the screw 45 being arranged to clamp said sleeve. 43 stationary within said bore 42 when desired; j
. Theheads 57 aresecured in both ends of the bore 42 and the screws 53 and 54 are in heads 57, with the said head' 44. open into sleeve 43. Oil cups are secured in the vaccumulating in the passage 52 may 48 and 49. The sleeve 43 is formed with ports 46 and 47 spaced from one another to alternately open and close the ports 48 and .49 respectively, as the said sleeve 43 and-head 44 reciprocate back and forth between the bumpers 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 the adapter 41 to su ply oil to the bearing surface between the box-e42 and sleeve 43 and the overflow oil therefrom be drainedthrough a petcock 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 the passages 51 and 50 respectlvely, 1n the adapter 41, connectors 72 and 73 are. formed inthe passage 52 and pipe 69 block,14 on respectively, to detachablyhold a hose 60, theoplposite. end of the hose .60 being secured to a' ousin 62 and cup 61, the'housing being rovirfed with flapper valves 63 an 64, an control arms '65 and 66 respectively. Before operating my invention the positionof the motor 2 is adjusted tore ate the-distance between the pulleys 7 an 8 to give a tight gripping .or loose sliding belt connection 74, by sliding the base 3 1n the guides and clamping the screws 5 in osi- 1n 1.77 will, read .w ere required on the sca e 76. The stroke of the tions so that the connecting rod 16 is adjusted by'setting' the dead center of the crank 10, to read where required on the scale 7 5',by turning the screw 13,-thus determining the length of the strokes of the iston 20 in the pum openings in t 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 required slots 29 thus holding the connecting levers 26 andlinks 25 in stationary positions.
The openings in the valves 31 areadju'sted to open and close alternately by the flappers 32, said flappers being controlled as required by the cams 34 which are swung about on the center'of the shafts'33 with relation to the .2
position of the 'levers' 36, the lugs 38 being set into the adjacent graduated notch 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 the rods 53 and 54 (Figure '5) being a justed to hold the heads 58 and 59 against opposite 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 the adapter 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 the bore 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 the electric motor 2 is operatively connected with the pump 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 the piston 20, provi ing the valve closures 24 of the pump 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 the flapper valves 31 open may also be regulated as desired, but the opening of the valves 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) between chambers 50 and 71 and between chambers 51 and 70 hence, since the pump 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 the applicator cup 61.
With the several adjustments made as to the position of the motor 2, crank 10, valves 22, valves 31, head 44 and bumper ends 5859, power is transmitted from the motor 2 through the pulley 8, belt 74, pulley 7, shaft 6 and crank 10 respectively. The turning movement of the crank 10 forces the piston 20 in the pump 17 to reciprocate through the shaft 18, and the connecting rod 16 connected thereto.
Pipe 68 leads to cylinder chamber 70 at the right of piston head 20 as viewed in Figures 1, 2-and 6, and pipe 69 leads to the other cylinder chamber 71. Now when piston rod 18 moves to the left (cams 34 holding closed flappers 32, both ends of cylinder) the air is sucked from chamber 51, Figure 5,
and the suction draws sleeve 43 toward the left end of chamber 42, until partition 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 through pipe 69 to chamber 50, from where it forces sleeve 43 toward the left. Hence on one side of partition 44 there is suction isochronously with a compression on the other side, thus operating the sleeve.
The housing 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 the cup 61 on the body. The mode of pneumatic delivery machine in general. The valves can also be permanently set in the adapter 41 forany mode of pneumatic delivery when using various sized cups 61.
The stroke of the crank 10 is lengthened or shortened when changing from a small cup 61 to a larger cup 61, to provide the necessary pneumatic volume.
