IRECEIVING MECHANISM FOR TUBULAR TRANSIT SYSTEMS.
SPEGIFIQATION forming part f Letters Patent No. 669,887, dated March 12, 1901.
Application filed July 10, 1900.
of pneumatic means for checking the speed of and ejecting carriers from a transit-tube, and has for its object to provide a more simple, compact, and eicientoperating mechanism therefor. This object I attain in the manner hereinafter set forth and particularly described, reference being had to the accompanying drawings,'in whichl Figure l is a vertical longitudinal section of a receiving mechanism constructed in ac- `cordance'with my invention, and Fig. 2 a detail section of trip-finger valve.
Like numerals of reference designate similar parts in both views.
Referring to the drawings, 1 is a section of W incoming transit-pipe; 2, an enlarged portion vthereof provided with ports 3, leading into an exhaust-pipe 4. A receiving-chamber 5, form- I ing acontinuation of 'transit-pipe 1, is normally closed at its outer end by a gate 6, operated by a piston 7 in cylinder 8. A receiving-table 9 is placed at the exit of receivingchamber to catch the carrier as it is ejected ytherefrom. A piston-valve 10, controlling the movements of piston 7, is normally held in-its upper position (see Fig. 1) bya spring 11, admitting air under pressure from any suitable source, such as the transit-pipe 1, through pipe 12 to the top of piston 7, and reversed by the admission of air under pres` sure'to diaphragm 13 from pipe 12, admitting pressure to the under side of piston 7 from thetransit-pipe or an auxiliary supply;
The diaphragm 13 and valve 10 are rigidly secured to a common valve-stem 15.l The valve-stem 15 is extended without the casing of the diaghragm 13 and provided with a.` knob 16 for hand operation.
A dnger 17, pivoted at 18 and provided with Serial No. 28,088. (No model.)
a projection 19 and a spriugpawl 20, normally seated on projection 19, is normally held in the position shown in Fig. 1, projecting into the path of the carrier at the outer side of the gate 6 by a spring 21.
A valve 22, having an annular recess 23, is mounted ona common valve-stem 24, witha diaphragm 25, and adapted to remain in whatever position it is thrown to.
The valve-stem 24 is provided upon its upper projecting end with a knurled knob 33 to allow of said valve being operated by hand when so desired.
`As a carri-er strikes the finger 17 said finger is thrown up out of the path of the carrier, the spring-pawl 20 riding under valvestem 24 and then returned by the action of spring 21, the pawl 2O carrying valve-stem 24, valve 22, and diaphragm 25 to the upper position and clearing the same. Air under pressure admitted to diaphragm 25 will throw vvalve 22 and stem 24 to the lower position.
The lower position of valve 22 opens communication between pipe 12, through pipe 26 and annular recess 23, "to diaphragm 13. Communication is always had .between diaphragm 25 through a pipe 27 with a port 28, communicating with receiving-chamber 5.
The operation is as follows: A carrier entering chamber `5 with speed from transitpipe 1 produces an excess pressure between its forward end and gate 6, which is communicated, through port 28 and pipe 27, to diaphragm 25, forcing it down andallowing air under pressure from the transit pipe 1, through pipe 12, pipe 26, and annularrecess 23, to throw diaphragm 13 and valve 10 to the lower position,admitting pressure through pipe 1 2 to the under side of piston 7, thereby 'raising gate 6. Upon the raising of gate 6 the carrier is ejected by pressure from the line onto table 9and in its passagethrows finger 17 up, the pawl 2Ol riding under valvestem 24. Upon the passage of the carrier beyond the finger said finger returns to normal position by the action of spring 21, and in so doing causes pawl 20 to carry valve 22 to its IOO
