PNEUMATIC-DESPATCH-TUBE APPARATUS- Patented Feb. 27, 1906.
Application filed March 24, 1905. Serial No. 251,770.
"To alt whom it may concern:
Be'it known that I, EDMOND A. FORDYCE,
of Boston, in the county of Suffolk and State.
of Massachusetts, have invented certain new and useful Improvements in Pneumatic-Despatch-Tube Apparatus, of which the following is a specification.
My inventionrelates to improvements in pneumatic-de'spatch-tube apparatus; and its object is. to devise an apparatus on the vacuum principle which is economical and efiicient and through which air passes only when the apparatus is in use transmitting carriers elevation, partly in section, showing the posi-' tion of the parts upon the position of a carrier for transmission at a substation.
Like letters of reference refer tolike parts throughout the several views.
The transit-tube A for transmission of the carriers from the central station to a substation has a bell-mouth'opening, as shown, to
receive the carriers. Said tube leads to the upward discharge-terminal A, having a suitable valve A? closing the despatch-opening and of the usual construction in the art. Con.-.
nected to said terminal A is a tube B for returning'the carriers to the central station, and at its upper end said tube is rovided with a carrier-inlet opening, closed by the valve B of usual construction, and at the lower end 01 said tube B is a suitable valve B for closing same. Connected to the lower end of said tube B by a joint -B is a tube B, which is in communication with said tube B by suitable slots, as shown. The tube B is connected below the floor-line (indicated by the letter R) to the chamber C, in which is located the valve D, closing the upper end of the passage J, which is in communlcation, by means of the pipe K, with the suction-tank K.
This valve D is pivoted at D in'the chamber O and has a rolling contact at D with the piston-rod D of the piston E, working in the cylinder E. To the lower end of the cylinder E is connected the pipe F, which when the apparatus is not in use in transmitting carriers is closed at its outer end to the atmosphere by the lever G, pivoted on the support G and with its upper end removedfrom contact with the magnet G, as indicated in %iston E is in the lower part of and the valve D is closed. With theparts in the position shown in Fig. 1 the pump is exhausting from the passage J to the pipe K, through the tank K, and throuh the upper and lower openin s L and M',.w ich connect the cylinder E wit the" assage J and pi e K, and this suction througi i'sa'id o enings and piston E, and as the vacuum created in said suction of the pump is equal on both sides of the iston E said piston drops"?? gravity to the lower part of thecylinder as shown, which closes the valve D. From the ma et G extend the wires H H, through-n 'ch when they circuit is closed through said wires the batter H as hereinafter explained, willener ize t e magnet G and cause the opera; tion ereinafter described.
tral station to a substation through the terminal A, it is inserted into. the bell-mouth,
drawing the upper end of the lever G inward toward the. magnet and opening the end of the pipe F to the atmosphere, and air entering through the pipe F under the piston E will destroy the vacuum below the piston E and force it upwardly, as the vacuum is maintained through the opening L. This operation will cause the valve D to open, so that air is drawn from the atmosphere at the bellmouth through the s stem to thetank K,- and the carrier will tube A and discharged through the. valve A at the terminal A. Aftera carrierh'as passed Fig. 1, and in this condition of the parts the the cylinder M produces a vacuum on bot' sides ottho cylinder by the openings L and M under the When a carrier is to be sent from the cen-,
e drawn through the.
Fig. 2, and striking'the finger. P will cause its inner end to cover the contact points ofthe wires P P, which will close-the circuit, as. just described, and energize the magnet G, v
1 the finger P said finger will move from the po- I sition shown in Fig. 2 to that shown in Fig. as the outer end is Weighted to normally prevent the closing of the circuit, and as the circuit is broken the magnet l'aecon'ies den-nergized and the lower end of the lever G will close the pipe F to the atmosphere, and as the suction continues through the passages l,
and M the vacuum will become equal and the 1 piston IE will gradually lower, thereby closing the valve D when the vacuum through the system is cut oil and. exists only below the valve D. When a carrier is to be sent from a substation to the central station, it is inserted into the tube B by opening the valve B and moving downwardly will strike the outer end of the finger Q, which will raise the inner end of said linger and close the circuit through the wires ll ll, and the. operation is the same as above described for raising the valve D to allow suction through the system to transmit a-carrierwhicli opens the valve B and drops said carrier into a suitable receptacle, indicated at ll. After the carrier has passed the finger Q, its inner end being weighted, it will move from engagement with the contacts and assume the position shown in Fig. 2.
The passage through the opening M to the bottom of the cylinder E is controlled by the valve N, which may be adjusted and held in its adjusted position by the nuts N. long lines the 'alve N is so adjusted that the fall of the piston E would be slow, allowing for the discharge oi the carrier bel'orc the valve l) is closed and the. vacuum cut oil,
while in short lines the valve would be u ide open. so that the piston llwould dropquickly because the carrier has a short distance to travel.
llaving thus described the nature of my in vention and set l'orth a construction embodyf ing the same, what I claim as new, and de sire to secure by Letters Patent ol' the United States, is-
