EDWARD J. COLBY, OF CHICAGO, ILLINOIS.
- COIN-RELEASED SPIROMETER.
SPECIFICATION forming part of Letters Patent No. 406,089, dated July 2, 1889. Application filed July 30, 1888. Serial No. 281,459. (No model.)
To all whom it may concern.-
Be it known that I, EDWARD J. COLBY,- a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented a certain new and useful Coin Controlled Lung Testing Device, of which the following is a specification.
My invention relates to .devices for testing the lungs, and has for its object to provide a simple, cheap, and convenient device for this purpose, so that the same cannot be operated except upon insertion of a coin.
My invention is illustrated in the accompanying drawings, wherein I have shown the same with certain modifications.
Figure 1 is a front view of the machine.
Fig. 2 is an interior view of the machine when at rest. Fig. 3 is an interior view of the machine when in operation. Fig. 4 is a diagrammatic view of the machine at the moment when it is put in operation. Fig. 5 is a crosssection detail of the coin-receiving slot. Fig. 6 is an interior View of a modification, showing a bellows instead of a cylinder. Fig. 7 is a similar view with the parts in operation. Fig. 8 is a cross-section of a modification. Fig. 9 is a side view of the same.
Like parts are indicated by the same letter in all the drawings.
A is a dial, upon which is the pointer-index A and the slot A of the proper size and shape to receive the coin.
A is the base, and A the case.
A is an air-tube, A the mouth-piece, and A a bracket for supporting the mouth-piece.
A are scale or index marks on the dial.
Connected with the slot A is the way B, beneath which is the receptacle B, pivoted at B and provided with a hook B at its other extremity.
Connected with the tube A is thetube C, which terminates in the cylinder C. Within this cylinder and projecting therefrom is the rod C having the rack C thereon and passing through the guide C The pointer A is secured on the shaft D, at the inner extremity of which is fixed the pinion D and the cam-wheel D having the notch D in its periphery. The pinion D engages the rack C Beneath the receptacle B is the guide E, p
which conducts the coin to the lower part of the case.
F is a coin.
On the rod C and within the cylinder C is the spiral spring G, fixed between the bottom of .the cylinder C and the cap G 011 the top of the rod C so as to hold the rod C normally in its elevated position. The cap G operates as the piston moves in the cylinder Cinnder the pressure of the air forced in through the pipe A and pipe C.
In the modification shown in Figs. (5 and 7 the tube A terminates within the tube H, which opens into the lower portion of the bellows H.
To the upper end of the bellows H socured the cord H which passes about the pulley H and thence to the rack-rod H. This latter engages the pinion D. The rack rod H is smooth at its upper end, is encompassed by the spiral spring H, and terminates above in the cap 11 and passes through the guide H so that it is kept normally elevated, as indicated in Fig. 6.
In the modifications shown in Figs. 8 and 9, J is a rock-shaft journaled in the bearings J J within the case A. This rock-shaft has onearm K pivoted to the link K ,which in turn is pivoted to the push-rod K which terminates in the button K The slot A in this case terminates in the guide L, through which the coin F passes. This guideway L is provided with a slot L, which receives the link L from the arm L on the rock-shaft J. The guide L is cut away at one side at M to receive the end M of. the elbow-lever M which is pivoted at M and the other end of which M is provided with the hook F to receive the notch D.
W is a counter-weight oifthe edge and near the periphery of the cam D It is so placed as to be a little oif center when the cam D is locked, and when the cam is released the counterweight slightly turns the cam, so as to to bring the point B or M" upon the edge of the cam back of the notch.
The use and operation of my invention are as follows: I will first describe the operation of the device as shown in Figs. 1, 2, 3, 4, and 5. The machine as set up is in the condition indicated in Figs. 1 and 2. If, now, a coin be introduced into the slot A it will pass into the way 13 and thence into the receptacle B and lift the hook B from the notch D, as indicated in Fig. 4. If, now, the person using the same applies the pressure of his lungs through the tube A and tube C to the cylinder C, that pressure will be applied to the upper part of the cap of piston G, and the same, together with the rod C will be forced downwardly. The rack C, by this motion being in engagement with the pinion D, will rotate the same, together with the pointer A, and thus the pressure applied and the strength of the lungs are indicated upon the dial. hen the pressure is released, the spring G immediately draws the rod C up and restores the parts to the position indicated in Fig. 2. The coin in the meantime has passed through the guide E into the base of the case, where it may be removed when desired.
The operation of the parts indicated in Figs. (3 and 7 is substantially the same, with the exception that here the pressure applied from the lungs through the tube A and tube II to the bellows 1i. expands the bellows, as shown in Fig. '7, thus drawing the rack-rod 11" downwardly, so as to make the pointer indicate the strength of the lungs. \Vhen the pressure is released, the spring II restores the parts to the position shown in Fig. (i.
In Figs. 8 and 9 I have shown a modification whereby not the weight of the coin, but a pressure applied through the coin, is made to release the iarts. Thus, by pushing the knob K inwardly the rod K moves, forcing the K inwardly, and thus, by means of the arm K turning the shaft G in its bearings, this same motion forces the arm L downward, carrying with it the link L and this carries the coin which has been introduced into the slot A into the guide L, resting against the end M of the elbow-lever M The pressure applied through the link L against the coin forces it downwardly through the guide L, turning the rock-shaft M 011 its bearing M and releasing the hook M and permitting the parts to operate when the pressure 01": the lungs is applied. This modification is equally applicable to the form of device shown in Fig. 2 0r Fig. (3.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is as follows:
In a coin-controlled lung-tester, the combination of a dial with indicating-hand thereon and coin-slot therein, with a blowing apparatus, a pinion on the shaft which supports the hand, and arack connected with such blowing apparatus, a spring to restore such rack to its place after operation, and a pivoted dog and cam which looks such pinion from motion, a coin-slide, an arm from such dog in the path of the coin, and a rockshaft with arm and push-button, so as to force said coin along its slide, and thus trip the dog and per mit the parts to operate.
