I Application filed September 19, 1889. Serial No. 324,457. (No niodel.)

To all whom it may concern.-

Be it known that I, FREDERICK E. ROBIN- SON, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lung-Test ers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to spirometers .or lung-testers, with the object in view to provide such an apparatus, that with blowing into a flexible pipe will indicate the capacity of the lungs only after depositing a coin of a certain denomination into an orifice leading therein, to be automatically returned to the depositor through another orifice after the required degree of capacity of the lungs has been demonstrated,and that otherwise will retain the coin thus deposited as a fee for the use of the apparatus; and with these objects in view my invention consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure l representsa front elevation of the interior of the apparatus, the front of the casing being removed; Fig. 2, a side elevation of the interior of the same, one side of the casing being removed. Fig. 3 is a front elevation of the apparatus; Figs. 4, 5, and 6, a plan, front, and side elevation of the automaticallytraveling brake-shoe and the main shaft; Figs. 7 and 8, a front elevation and sectional side elevation of the air-escape valve and its automatic lifting device. Fig. 9 isa sectional elevation of the air-escape valve, and Fig. 10 a front elevation; Fig. 11, a transverse vertical section on line w m in Fig. 10, and Fig. 12 a plan view of the coin holder and carrier.

Corresponding referential characters in the several figures of the drawings designate like parts. V v

In the bottom of a casing 1 is arranged a reservoir divided by a vertical'diaphragm 2 into a chamber 3 and 4, communicating through an opening below diaphragm 2. The chamber 3 of this reservoir is hermetically closed on top, only communicating with a pipe 5, the upper elbow end of which is projected through the front of easing l, where it has coupled a flexible tube 6, provided with a mouth-piece 7. The chamber 4 of the reservoir is upwardly extended and contains a float 8, rigidly secured to the bottom end of a vertical rod 9, projected through a hole in the top of such chamber, and with its upper end guided in a hole of a cross-bar 10 of casing 1. The reservoir being filled with water to near the top of chamber 3, byblowing into mouth-piece 7 the pressure produced will displace a part of the water contained in chamber 3, forcing the same info chamber 4,

wherein, with rising, the Water will lift float- 6 8 proportionally to theamount of air forced into chamber 3. Near its upper end is adj ustably secured upon rod 9 by a set-screw a collar 11, provided with a hook or eye for connecting therewith one end of a cord orchain 7o 12, the opposite end of which cord or chain, after winding upon the rim of a policy 13 one or several revolutions, is secured on such pulley. This pulley 13 is rigidly mounted upon a shaft 14 pivoted in suitable bearings between the front and rear casing l, and upon this shaft is also rigidly mounted a pulley 15, upon the rim of which is wound and secured a cord or chain 16, passed over a pulley 17, and having a weight suspended to its opposite end. The pulley 17 is rigidly mounted upon a shaft 19, pivoted in a suit able bearing in the rear of the casing and V projected through the front of the casing, where an indicator-arrow 20 is secured thereon in front of an index-dial 21,,graduated to indicate the amount or pressure of the air forced into the reservoir. It willbe readily seen that the lifting of float 8 and rod 9 Will thus rotate shaft 14, from which again, by 0 cord 16, the motion will be transmitted to shaft 19, carrying the indicator-arrow 20.

Upon cross-bars 22 of thecasingare secured longitudinal bars 23 andv 24, both on horizontal lines parallel with each other and 5 one vertically in a' line above the other. These bars 23 and 24 provide; a track for a carriage 25, consisting of a rectangular frame that has holes in the upper portion of its side bars for bar 23to pass through, and an eye26 00 to its bottom bar for bar 24 to pass through, in l a manner that this carriage will be supported. 1

and guided on bars 23 and 24 to reciprocate horizontally thereon. To an eye 27 of the top bar of carriage is secured the end of a chain or cord 28, the opposite end of which being secured to the rim of a pulley 29, also rigidly mounted upon shaft 14; and to an eye 30 of the top bar of carriage 25 is secured one end of a cord 31, which, after passing over a sheave 32, pivotally secured in a bracket of one of the upper cross-bars 22, has suspended to its opposite end a weight Thus the rotation of shaft 14, by the rising and sinking of float 8, will also-reciprocate the carriage 25. In about the middle of its top bar the carriage 25 has fixed a spout 34, which, when said carriage is on its extreme left-hand position, will be in position just below an inclined spout 35, projected through the front of casing 1, where it communicates with the slot of a plate 36, into which a coin being dropped will slide down through spout 35 into spout 34. The carriage 25 is also provided with a vertical rod 37 and an angular rod 38, both serving as guides for a beam 39 to slide up and down thereon on an angular course corresponding with the angle of rod 38, while for rod 37 7 said beam is longitudinally slotted, and to clear the beam 39 on its vertical movement the side-bars of carriage 25 are notched on its upper position, will engage the lower end of spout 34, and which is concaved between said prongs, while the upper end of lever 40 is chamfered to provide a seat for a coin of the intended.denomination, which, when dropped through spout 34, will rest be-. hind the. concave of plate 42. v

The beam 39, with pendulum-lever 40, is counterbalanced by a lever 43, mounted upon a shaft 44, pivoted in suitable bearings in the front and rear plates of easing 1. A rod 45, secured to beam 39, is extended upward through a slot 46 in the top bar of carriage 25, and the upper extremity of this rod 45 is provided with an eye coupled to the end of the longer arm of lever 43 by a cord or chain 4'7, while to the hook end of the opposite shorter arm of lever 43 is suspended a rod 48, carrying a cup-shaped weight 49, into which, for accurate adjustment, shot can be added. The counterbalancing is so adjusted that the weight 49 will raise the beam 39 with pendulum-lever 40, and will hold it to its upper position as long as no coin is placed therein, but that the weight of the coin inserted will cause the beam to sink to its lowermost position, thereby lifting the weight 49. Against the rear face of the lower portion of pendulum-lever 40 is pivoted again a small pendulum-lever 50, the upwardly-extending arm of which will butt against a shoulder 51, allowing such lever 50 only'to swing to one side,

and being held stiff toward the other side. This lever 50 is rigid, with its pivot-pin 52 projected through a hole in lever 40, and having to its forwardly-projecting end a gravitating crank 53, tending to hold said lever 50 on its vertical position. The carriage 25 being pulled horizontally toward shaft 14, by the rotation of such shaft from the rising of float S the lower end of pendulum-lever 50, when passing the upturned end of a bar 54, will pass over such bar end by swinging to clear the same, while, with returning, said lever 50 being held from swinging by shoulder 51, the lever 40 will have to swing sufficient for the coin to roll out from behind plate 42, and again with moving the carriage 25 far enough to the right until the lower end of lever 40 will be brought in contact with another bar 55 it will be swung in the opposite direction sutliciently for the coin to roll out. Both bars 54 and 55 are secured to the lower cross-bars 22, and the bar 55 may be adjustably secured for regulating the distance of the carriage 25 to-travel before the coin is dropped by lever 40.

The operation of the above is that, after a coin has been inserted to sink the beam 39 with lever 40 down to its lowest position in carriage 25 and then blowing air into the reservoir, the carriage will move to ward the right,

and when sufficient air-pressure is applied for the carriage 25 to reach a position where the lever 40 is turned by bar 55, so the coin is discharged from lever 40, this coin will drop upon an incline .56, whence, through an orifice in the front of the casing, it will drop into a cup 57, and is thus returned to the operator; but when the lung-power is not suflicient for moving the carriage 25 the required distance, the carriage, with returning, will bring the lower end of lever 50 into contact with the end of bar 54, whereby the coin is discharged to remain inside the easing, into a receiver placed therein in proper position,

and is then lost to the operator. The angular down movement of beam 39, guided by rod 38, is to correspond with the curved path of the end of lever 43 to hold rod 45 and cord 47 as near as possible on a vertical line during the time the beam 39 with lever 40 is on its down course, after which the cord 47 and lever 43 will accommodate themselves to the movement of the carriage 25.

For the purpose that the apparatus may not be used as a lung-tester without first depositing a coin into the orifice of plate 36, I have arranged above shaft 14 a horizontal plate 58, secured between the front and rear of easing 1, and this plate 58, I provide with guide-strips 59, for a shoe 60 to slide between. To one end of shoe 60, I secure one end of a cord or chain 61, the opposite end of which, after passing over a sheave 62, is secured upon the rim of a pulley 63, rigidly mounted upon shaft 14. The opposite-end of shoe 60 has attached one end of a cord 'or chain 64, which, after being passed over asheave 65',

IIS 7 has suspended to its opposite end a weight 66. The rod 48, suspended to lever 43, when on its down position extends with its lower end past the chamfered end of sheave 60 into a hole in plate 58, so that said shoe 60 will butt against rod 48 as long as the same has not been lifted to clear 7 said shoe 60 by the inserting of a coin, and will thus be prevented from moving, whereby the shaft 14 will be prevented from rotating, which, again, will prevent the float 8 from rising by blowing air into the reservoir.

For the purpose that a person may not be able to move the carriage by intermittent blowing-that is, by closing the mouth-piece 7 with the lips while taking in a new breath of air through the nose and then blowing with renewed forceI have connected with pipe 5 a gravitating safety-valve 67 and an air-stop valve 68, which latter is to be adjusted to allow a small leakage of air, while the stem of valve 67 is coupled to the end of a horizontal rod 69, guided in bifurcated brackets 70 of the valve-casing and pivotally coupled with its opposite end to an ey e-screw 71,- secured into the rear face of the front plate of easing 1. Upon this rod 69 is sleeved a pendent pawl 72, that with its lower end rides upon the serrated rim of a large wheel 73, a segment of which rim is notched out. This wheel 73 is rigidly mounted upon a shaft 74, having also mounted two pulleys 75 and 76, the one 75 having a cord or chain 77 secured with one end, to the opposite end of which is suspended a weight 78, and the other pulley 76 also having a cord or chain 79 wound thereon and secured with one end, while its opposite end is secured upon a pulley 80, rigidly mounted upon a shaft 81, that also has mounted a small pulley 82, upon which is wound and secured one end of a cord or chain 83, being coupled with its opposite end to the hook of a collar 84, adjusta bly secured upon rod 9 by a set-screw.

The small amount of air escaping through valve 68 will not be of consequence with a steady blow of air into mouth-piece 7 where- 1 by as the float 8 rises the wheel 73 will be rotated in the direction of the arrow, loosely serratures, will move with such wheel 73 uni i L til, butting against stud 85, secured to the casing of valve 67, and with being swung to a vertical position, this pawl 72 will lift valve 67 and will allow the air to escape through the open side nozzle 86 of the casing of such valve, when at once thefloat will sink, and all the moving parts of the apparatus will be automatically reversed by the several counwithout engagement, and the wheel 73 can :contihue to be rotated in the reverse direction by the tension of weight 78 until reach- ;ing its starting-point, where the rim of such wheel 73 has a segmental notch 87 for the pawl 72 to be released of its support on the -wheel, and the valve 67 will be closed by its own gravity and the gravity of rod 69. Thus it will be readily seen that with dropping a coin into orifice 36 and then blowing into mouth-piece 7 the carriage 25, the brake-shoe 60, and the wheel 73 will all be moving with the rising of float 8, and with a sufficient uninterrupted blast of air the coin will bedischarged into receptacle 57; that without first dropping a coin into the apparatus the brake shoe 60 will prevent the parts from moving, and that a suspended blast of air will open valve 67 for the air to escape.

A niche 88, with a glass plate 89 in its inward end, may be provided, through which glass the plate 42, with the coin deposited behind, can be seen as moving along sidewise,

and against the front of the apparatusmay be secured a forked bracket 90, for holding the mouthpiece 7 and supporting hose 6 while not used.
