@Ultim-RELEASED LUNG-TESTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 642,149, dated January 30, 1900.
Application filed March 22, 1898. Serial N- 6'74,726. (No model.)
To all wtom it may concern,.-
Beit known that I, BENJAMIN MCKENZIE, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Coin-Re leased Lung-Testing Apparatus, of which the following is a specification.
My invention relates to improvements in coin-released lung-testing apparatus for bellows provided with a gravity exhaustyalve; and it consists particularly in means for automatically holding said exhaust-valve open and coincontrolled means for mechanically closing the valve.
In the accompanying drawings, forming part of this specification, Figure lis a front elevation of my improved apparatus. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section. Fig. 4 is a longitudinal section of the coin-actuating means for closing the exhaust-valve of the bellows. Fig. 5 is a side view of the same. Fig. 6 is a longitudinal section thereof with the parts shown in operating position. Fig. 7 is a section on line oo of Fig. 4, and Fig. S isa detail illus-` trating a signal-whistle forming part of my invention.
In the drawings, A represents a suitable box or case made up of the hollow base 2 and the upper case 3, having a glass front 4. Centrally arranged in the case 3 and sliding in the met-al cylinder 5 is the bellows 6, secured to Jthe top 7 of the base 2. The cylinder 5 is formed with a vertical slot S in its front and rear sides, through which parts connected with the bellows pass. In the top of the bel lows is formed an enhaust-opening 9, adapted to be closed by the valve l0, having hingesupport ll upon the top of the bellows. Connected with the forward end of the valve is a cord 12, extending upward and passing over the pulley 13, thence through the cylinder and over a pulley 14, its end being connected with the weight 15, working in a vertical tube 16. The weight l5 counterbalances the weight of the valve 10, so as to hold the same normally in open position, as shown in Fig. 2.
The valve l0 is designed to be closed by the following-described mechanism: Secured in the forward wall 17 of the base of the apparatus is the cylinder 1S, which is formed with the exterior flange 27, having screw-openings by which it is attached to the inner side of the wall 17. Within the cylinder is slidably arranged a second cylinder 19, provided with the actuating-handle 20, projecting through an openingin the front end of the outer cy1- inder 18 and through the angle-plate 2l, secured to the front side of the machine-base. The inner cylinder is provided with a rearwardly-extending central rod 22, surrounding which is the coil-spring 23, one end of said spring bearing against the forward closed end of said cylinder and the other end abutting against the screw-cap 24, which closes the inner end 0f the outer cylinder 1S, the rod 22 working through an opening in said screwcap, as shown. The forward end of the inner cylinder 19 is formed with a transverse slot 25, extending vertically therethrough. The upper side of the forward end of the outer cylinder is formed with a slot 26, registering with the slot 28 in the top of the angle-plate 21, both of which slots register with the ver tical slot in the inner cylinder when said cyl'- inder is in forward position, as shown in Figs. 4 and 5. Vthen a coin is dropped through the opening 28 in the outer plate 21, it Will stand in the slot 25, resting upon the bottom of the outer cylinder. As said cylinder is forced rearwardly by pressing the handle the coin 29 will becarried with it and will drop out through the opening 30 in the lower side of the outer cylinder, as shown in Fig. (i. To prevent the turning of the inner cylinder, it is provided with laterally-projecting pins 3l, sliding in slots 32 in the outer cylinder 1S.
In order that the exhaust-valve l0 may be closed in the operation of the cylinder just described, a bar 33 is slidably arranged upon the top of the cylinder 1S, the rear end of said bar being connected with one arm of the bellcrank 34, having pivotal support 35 in the top of the base of the machine, the other arm 36 of the bell-crank supporting a vertical rod 37, projecting upwardly at the rear side of the cylinder containing the bellows and Working in a suitable guide 3S, as best shown in Fig. 2. The forward end of the bar 33 is beveled, as shown in Figs. 4 and 6, and slides between the similarly-beveled guides 39, extending upwardly from the cylinder 18. `Secured. to the top of the bar 33 in the rear of the beveled portion is the spring 40, having a downwardly projecting pin 41, which projects IOO f l ellai through a slot 42 in the top of the cylinder 18, causing the lower end of said pin to stand in a socket 43, formed in the closed end of the inner cylinder 19 at the rear of the vertical slot 25. The wall 44, forming the forward side of said slot 25, is cut away at its top, so as to allow said inner cylinder to be forced inward in the outer cylinder (when there is no coin in place) without interfering with the downwardly projecting portion 41 of the spring 40.
To actuate the machine, a coin of such size will have to be used that when placed in the slot 25, as shown in Fig. 5, it will abut against the downwardly-projecting portion 41 of the spring 40. As the handle 20 is actuated to carry the inner cylinder 19 inward against the tension of its spring 23 the rod 33 will be carried rearwardly by means of the coin 29 abutting against the downwardly-projecting portion 41 of the spring 40. As said bar is forced rearwardly the forward end of the spring 40, riding upon the cross-pieces 58, will be gradually raised as it reaches the position shown in Fig. 6, thereby carrying its downwardly-projecting portion 41 above and out of contact with the coin 29, allowing said coin to drop through the opening 30 in the outer cylinder. The actuating-handle then being released, the inner cylinder and the bar 33 will be carried back to normal position by the spring 23, since the end of the pin 41 will still be in contact with the front wall of the inner cylinder 19. Suitable guides 45 for the bar 33 are secured to the top of the cylinder 1S. It will thus be evident that as said bar 33 is carried rearwardly, as above described, the Vertical rod 37 will be raised by means of the bellcrank 34, said rod striking the rearwardly-projecting end of the valve 10, raising the same to turn the valve into closed. position. The bellows can then be blown up by the operator by the use of the tube 46 and its mouthpiece 47, and he can then fill the bellows with air and raise the same.
At the front of the upper case is arranged a glass tube 57, and adjacent to said tube is a graduated scale 48, indicating the measure of capacity of the lungs. A ball 49 is arranged in the tube 57 and 'is attached to a cord 50, which passes upward over the pulley 51, then downward over the pulley 52 at the bottom of the case, its other end being connected, as shown in Fig. 2, to the bellows. In order to give a signal to the operator when the bellows has been inflated to the greatest degree, a whistle 53 is arranged in an opening 54 in the top'of the bellows. The lower end of the opening 54 is closed by a valve 55, to which is connected a vertical rod 56, projecting upward through the opening 54, as shown in Fig. 8. When the bellows has been raised sufficiently to cause the rod 56 to come in contact with the top of the case, the valve 55 will be forced open, allowing the air in the bellows to pass through the whistle 53 and sound a signal. As the bellows drops back to collapsed position the valve 10 will be opened by the counterbalancing-weight,
I claim- 1. An apparatus of the class described,com prising in combination the expansible airreceiver, the means for inflating the same, the exhaust valve, ythe counterbalancingweight normally holding said valve in open position, the arm carried by said valve, the devices arranged adjacent to said arm and adapted when operated to engage said arm to close the valve, and the coin-controlled means for actuating said mechanism.
2. A lung-testing apparatus comprising in combination the bellows, its gravity exhaustvalve having a projecting arm, the means for normally holding said exhaust-valve open, the devices arranged adjacent to said arm and adapted when actuated to engage said arm to close the valve, and the coin-controlled Y means for actuating said devices.
3. An apparatus of the class desc'ribed,com prising in combination the bellows,its gravity exhaust-valve, means for normally holding said exhaust-val ve open, the devices arranged adjacent to said valve and, adapted when actuated to engage the same to carry it to closed position,the coin-receiving plunger arranged in connection with said devices, and adapted when supplied with a coin of certain size to be operated to actuate said valve-closing devices.
4. An apparatus of the class described,comprisin g in combination the bellows, its gravity exhaust-valve, and the means for normally holding the same in open position, the mechanism arranged adjacent to said valve, and adapted when actuated to carry said valve to closed position, the spring-restrained coinreceiving plunger, the device arranged intermediate of said plunger and the valveclosing mechanism, and adapted to be operated to close said valve when the plunger is supplied with a coin of certain size,and forced inward against the tension of its restrainingspring.
