RECEIVING MECHANISM FOR TUBULAR TRANSIT SYSTEMS.

SPEGIFICATION formingpart of Letters Patent N 0. 669,888, dated March 12, 1901.

Application filed July 10, 1900- To aIZZ whom it may concern:

Be it known that I, WASHINGTON A. H. Bo- GARDUS, a citizen of the United States, residing at The Montana, One Hundred and Twenty-fourth street and Mount Morris avenue, in the city of New York, county of New York, and State of New York, have invented a new and useful Improvement in Receiving Mechanism for Tubular Transit Systems, of which the following is a specification.

My invention relates to the general class of tubular transit systems, and more particularly to receiving mechanism therefor, consisting of pneumatic means for checking the speed of and ejecting carriers from a transittube, and has for its object to provide a more simple, compact, and efficient operating mechanism therefor. This object I attain in the manner hereinafter set forth and particularly described, reference being had to the accompanying drawings, showing a vertical longitudinal section of a receiving mechanism constructed in accordance with my invention, as Figure I, and a detail of tripvalve, as Fig. 2.

Referring to the drawings, 1 is a section of incoming transit-pipe; 2, an enlarged portion thereof provided with ports 3, leading into an exhaust-pipe l. Areceiving-chamber5,forming a continuation 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 5 to catch the carrier as it is ejected therefrom. A pistonvalve 10, controlling the movements of piston 7, is normally held in its upper position (see Fig. l) by a spring 11, admitting air under pressure from enlarged portion 2 of the transit-pipe 1 through pipe 14 to the top of piston 7 and reversed by the admission of air under pressure to diaphragm 13, admitting pressure to the under side of piston 7 from the transmitter-pipe or an auxiliary supply.

The diaphragm 13 and valve are rigidly secured to a common valve-stem 15. The

valve-stem 15 is extended without the casing of diaphragm 13 and provided with a knob 16, forming a shoulder for engagement with a locking-pin 17 and also serving as a means of operating the valve 10 by hand.

The diaphragm 13 is connected by pipe 18 Serial No. 23,089. (No model.)

with a port 19, communicating with the outer vend of receiving-chamber 5.

The locking-pin 17 serves as a valve-stem for a diaphragm 20 and is normally held by spring 21 in a position to engage knob 16 of valve stem 15 when said valve-stem 15 assumes its lower position. The outer end of locking-pin 17 is extended through the easing of diaphragm 20 and provided with a knob 22 for hand operation. The diaphragm 20 is connected by pipe 23 with pipe 14: from transit-pipe 1.

A finger 24:, pivoted at 25 and provided with a projection 26 and a spring-pawl 27, normally seated on projection 26, is normally held in the position shown in the drawings, projecting into the path of the carrier at the outer side of the gate 6 by spring 28.

A valve 29, placed in the pipe 23 and having an annular recess 30, is normally held in the position shown in the drawings by spring 31, its lower extremity extending a short distance below its casing.

The upper end of the stem of the valve 29 projects through the casing thereof and is provided with a knurled knob to allow of the operation of said valve by hand.

As a carrier strikes finger 24; said finger is thrown up out of the path of the carrier, the springpawl 27 riding under valve 29 and then returned by the actionof spring 28, the pawl 27 carrying the valve 29 to its upper position, allowing a momentary air-pressure to pass from pipe 14 through recess 30 and pipe 23 to diaphragm 20 until the pawl passes from under the lower extremity of valve 29 and allows it to fall again under the action of spring 31, cutting ofi the pressure from pipe 14 and exhausting pressure from diaphragm 20 through exhaust-ports 32.

Communication is always had between diaphragm 13 and port 19.

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 19 to diaphragm 13, throwing it, with valve 10, down and opening gate 6. As the diaphragm 13 is thrown down locking-pin 17 snaps under pressure of spring 21 behind knob 16 and holds the diaphragm 13 and valve 10 in this position until the carrier has passed the gate 6 and trip-finger 24, propelled by pressure from the line. The return of finger 24 by spring 28 causes the pawl 27 to raise Valve 29 momentarily, allowing a puff of air from pipe 14: to pass to diaphragm 20, which acting against spring 21 Withdraws locking-pin 1'7, allowing valve 10 to return to its normal position and close gate 6. The return or fall of valve 29 exhausts diaphragm 20 and the cycle of movement is complete, each moving part having assumed its original position ready for the reception 1 of another carrier.

It is obvious that various changes may be made in the construction and detail of this device without departing from the spirit of my invention.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a receiving apparatus for transit-tube systems, the combination with a receivingchamber, a gate therefor and pneumatic operating mechanism for said gate, a valve for controlling said pneumatic operating mechanism, a spring normally holding said valve in one position, a diaphragm for throwing said valve to its other position, means of communication between said diaphragm and said receiving-chamber, and means for locking said valve in and releasing the same from said latter position, substantially as described.

2. In a pneumatic gate-controlling apparatus, in combination with a transit-tube and gate therein, pneumatic operating means for said gate, a valve for controlling said pneumatic operating means, spring means for normally holding said valve in one position, a diaphragm for throwing said valve to its opposite position adapted to be operated by excess pressure caused by the cushioning of a carrier before said gate, a locking-pin adapted to lock said valve when thrown to said lastmentioned position, spring means normally holding said pin in its locking position, a diaphragm for withdrawing said pin, an auxiliary air-supply for said latter diaphragm and controlling mechanism for said auxiliary airsupply, substantially as described.
