SPECIFICATION forming part of Letters Patent No. 514,503, dated February 13, 1894.

Application filed March 15, 1893- Serial No. 466,133i (No model.)

To cZZ whom t may concern:

Beit known that lI, J oHN SCHNEPF, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in Pneumatic Signal-Switches, of which the following is a specilication.

My invention relates to a new and useful improvement in a pneumatic signal switch of to which the following taken in connection with the` accompanying drawings is a full, clear, and accurate description.

In the accompanying drawings, Figure i is a front view representing a numerated dialx5 a pointer and a push button with its setting device. Fig. 2 is a central vertical section of my pneumatic signal switch. Fig. 3 shows the pointer and the indicator setting device. Fig. i is a rear view of my pneumatic signal zo switch.

Corresponding let-ters indicate correspond' ing parts.

A represents a circular base having a stopcocli fitted in its center.

h represents a push button screwed to a rod D, this rod D passes through a central hole in the stop cock indicator and is fastened to the circular plate E.

d is a washer that is held to the bottom ot 3o the stop-cock casing by a hollow shoulder nut O, so that the rod D can pass through it.

F is an air holder or bellows screwed to the circular plate G by' nut f', having a hole through its center and thereby connecting tube H with I screwed in the casing K.

The stop-cock C has a groove out in its circumference J to be used as an air chamber and a slot J is out in the stop-cock to connect the air space K with the air space J or 4o grooved circular air chamber.

, L L are tubes screwed in the casingofthe stop-cock K, the several tubes are shown in Figs. 2 and 4.

Having described the mechanism of my invention, I will now explain its action. The revolving indicator is turned to No. l on the dial as shown in Fig. l, the push-button b is pressed inward causing the rod D andthe circular plateE to compress the air holder F, and

forcing the air that it contains into the tubo 5o H, thence to the air chamber J, which connects with a slot or groove marked .I and thence to tube L. It will be seen that the springfin the air holder acts on the push-button plate to bring it into its normal position. By my invention, as may be readily seen, signals may be given at any desired number of different points. As shown in the drawings, there are eight otsuch points, and as above' suggested all that is necessary is to 6o turn the stop-cock in such manner that the index finger or pointer c shall point to such one of the figures on the dial as correspond .with the place or locality to which the signal is to be sent. Thereupon pressure upon the thumb button l) actuates the air compressor and the air is forced through the appropriate tube L to the desired place. Ot course there are as many of these tubes L as there are places to be con1iected-wtl1,they 7o heilig arranged around the dial, as already indicated.

Having described my invention, what I claim is l. A pneumatic signal switch, comprising the following elements, a stop cock provided with an air passage or groove, a yielding air compressing device, a rod to compress the said device, a tube connecting with said groove in the stop-cock, and other tubes con- 8o necting with an air passage in the stop-cock, which connects with said groove therein, substantially as set forth.

2. A pneumatic signal switch, comprising the following elements, a stop cock, pro- S5 vided with an air passage or groove, an opener upon said stop-cock, an index or dial adjacent to the opener, a yielding air compress ing device, a rod to compress the said device,

a tube connecting the said device with said 9o groove in the stop-cock and other tubes connecting with an air passage in the stop-cock, which connects with said groove therein, substantially as set forth.

3. A pneumatic signal switch comprising g5 the following elements, a stop cock provided with an air passage or groove, a yielding air compressing device, a rod to compress the said device, Which passes through the stopmy invention I have signed my name, in prescoek, a tube connecting the said device with. ence of two witnesses, this 14th day of March, said groove in the stop-oook and other tubes 1893.

connecting with an ail' passage in the stopf JOHN SCHNEPF. 5 oook, Which connects with said groove there- Witnesses:

in, substantially as set forth. FRANCIS F. ATKINSON,
