Description

pair of valves is connected by tube 46 to the tracker bar 45 and has communication with the tracker opening 46, for admitting atmospheric air to the tube 46 when the perforations 44 and 46 in the note sheet 47 register with the tracker openings 44 and 46.
In operation, when one of the perforations 44 of the note sheet 47 is brought into register with the tracker bar opening 44*, air is admitted to the tube 44 and through the con necting block 30 of the forward valve, as
shown in Fig. 1, into the tube 43, which leads to the pocket 14 of the rear valve by way of the duct 15. Air being thus admitted to the pocket 14, and the exhaust chamber 23 being above the diaphragm or pouch 17, raises the latter momentarily to unseat the valve 27 and establish communication between the exhaust chamber 23 and the pneumatic 38, through the tube 37, nipple 36, and duct 35. Then the valve 27 is thus raised its upper face seats against the cap plate 12, closes the atmospheric opening 31 to the valve chamher, and also closes the passage 32 which leads down through the connecting block 30 from the tracker tube 46. As the tracker tube 46 is closed, and as the passage 32 is closed by the valve 27, the tube 42 is placed under vacuum by reason 0t its connection with the nipple 16, which leads through channel 15 into the pocket 14 of the front valve, which pocket 14 is exhausted of air through the bleed hole 24 in the diaphragm 17. Thus the diaphragm 17 of the front valve is permitted to fall and the valve 27 above the diaphragm is permitted to seat.
The seating of the valve 27 closes communication between the pneumatic 39, connected to the front valve chamber 25 by means of the nipple 36 and tube 37, as shown in Fig. 1, whereby the pneumatic 39 is opened to the atmosphere through the pas sage 31, and is thus permitted to expand. At the same time, the valve 27 uncovers the passage 31 to the atmosphere, and also opens the relatively small passage 32 which leads to the cross tube 43 to admit air to the pocket 14 of the rear diaphragm 17. This permits the rear diaphragm to remain raised, as shown in Fig. 1, and to thus hold the rear valve 27 upwardly from its seat 28. The parts remain in this position until the perforation 46 of the note sheet is brought into registry with the opening 46 in the trackerbar. When this occurs, air is admitted to the tube 46, through connecting block 30, into the cross tube 42 and into the front pocket 14. Air being thus admitted beneath the diaphragm, the suction in the chamber 23 lifts the diaphragm and the valve 27 therewith so as to effect the seating of the rear valve and the consequent retaining of the front valve in raised position.
It is thus seen that I have provided a pair of main valves which are so connected together that it is not necessary to provide auxiliary valves, as the main valves themselves act for each other as auxiliary valves. The pneumatics 38 and 39 may be connected to expression devices, slide or other form of valves, or to any other mechanical devices which are adapted to be actuated or controlled from a note sheet.
I claim 1. In pneumatic mechanism, a pair of valves, a pouch for each valve, an exhaust chamber communicating with one side of said pouches, a pocket communicating with the opposite side of: each pouch, and a duct leading from each pocket and adapted to be opened and closed to the atmosphere by the 1 second valve for holding said second valve to its seat, and a connection between the second valve and the first valve whereby to maintain the first valve in unseated position.
5. In pneumatic mechanism, a pair of valves, means to initially open one of the valves, a connection between said valves adapted to close one valve upon the opening of the opposite valve, and means between the opposite valve and the first valve to retain the first valve open when the second valve is closed. 7
6. In pneumatic mechanism, a valve chest having an exhaust chamber therein, a pair of pneumatics connected to the exhaust chamber, a valve for each pneumatic controlling communication between the separate pneumatics and the exhaust chamber, means for initially opening one of the valves whereby to exhaust one of the pneumatics,
a connection between said valves adapted to E. A. CAMPBELL.
