PNEUMATIO-DESPATCH APPARATUS- Specification of Letters Patent.

Patented May 7, 1907.

Application filed May 24, 1906. Serial No. 318.474.

To all whom it may concern:

Be it known that I, FRED R. TAISEY, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Pneumatic-Despatch Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide an improved terminal for pneumatic despatch apparatus, where a carrier director projects into the passage-way through the terminal and deflects a carrier through the discharge opening of the terminal when said carrier is so formed as to lock the director in position, the locking arrangement being such as to be actuated by a differently formed carrier so that the latter will move the director out of the way and pass.

The various features of this invention will be more fully understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a central longitudinal section through a terminal in the despatch apparatus the parts being in nor mal position. Fig. 2 is a central longitudinal section through a terminal with the di rector fully operated-by one carrierand the other carrier being stopped. Fig. 3 is the same but showing the director locked and the carrier being discharged from the terminal. Fig. 4 is an elevation of a portion of a pneumatic despatch apparatus, parts being in section. Fig. 5 is a transverse section on the line 55 of Fig. 1, excepting that no carrier is shown in Fig. 5. Fig. 6 is an elevation of the rear part of a director and associated-parts for stopping the carrier while the director is elevated. Fig. 7 is a detail on a large scale of a portion of the director and a locking-trip thereon.

The part of a pneumatic despatch apparatus which is shown consists of a straight por tion 10, semicircular portions 11, a terminal 12, out-going portions 13 and 14 and a second terminal 15.

The terminal 12 has an extension 16 at one side with a discharge opening 17' there through that is closed by a valve or clapper 18 closed by a spring 19 and by suction. A guide 20 is pivoted in the discharge opening so that the inner edge thereof will be flush with the interior surface of the passage-way through the terminal.

Opposite the discharge opening there is a narrow chamber in a casing 26, and in this chamber I pivot a director 27 by a pin 28 which has a spring 29 on it that causes one end of the director to project at an inclination across the passageway for the carriers 30 and 31. To thecasing 26 there is secured a fixed stop 32 in position to be engaged by a locking-trip 33 that is pivoted between its ends on a pin 34 to the director and is returned to normal position against a stop 35 by a spring 36 whenever said locking-trip is actuated.

As seen in Fig. 2 the carrier 30 has on its head a central projection 37 that is adapted to engage the lower end of the locking-trip 33 before the head of the carrier engages said director. When the locking-trip is actuated, first it assumes the position shown in Fig. 2 and engages the fixed stop 32, and then the carrier is deflected by the director through the discharge opening. The carrier 31 has no projection 37, consequently its head comes in contact with the director 27 before the locking-trip is engaged. The director is then thrown up out of the way, from the dotted line position shown in Fig. 3 to the full line position, and the carrier 31 passes on. A buffer 38 receives the blow of the director when it is actuated by the carrier.

To prevent one carrier following another while the director is in the locked position, I provide a carrier stop 40 pivoted on a pin 41 and actuated by spring 42 so that the outer end of the stop will bear against one end of the directorand the other end of the stop will project into the passage-way for carriers. A latch 44 is pivoted to the casing on a pin 45 with the free end thereof adapted to engage notches in the outer end of the carrier stop 40 and the whole is set in a position to stop a carrier when the director is in the partially operated position shown in Fig. 3. An arm 46 on the end of the director engages a pin 47 on the latch and holds it normally in the position shown in Fig. 1, the latch being above the carrier stop and then the stop will permit the carrier to pass it. is partially operated as in Fig. 3, the spring 42 forces the outer end of the stop against the But when the director end of the director as it changes position, whereupon the latch drops into the lower notch in the trip and that causes the inner end to project far enough to stop a carrier. The inner end of the stop 40 is curved, as shown, in the direction of movement of the carrier, so that when the latch 44 is elevated, the carrier wigvplush on by the stop 40.

at I claim as my invention and desire to secure by Letters Patent is:

1. A terminal in a pneumatic despatch apparatus having a passage-Way therethrough and a discharge opening, a director projecting into the passage-way therein in a position when locked to deflect a carrier through the discharge opening, and means pivoted on v the deflecting end of said director which rojects into the assage-way and operable y a carrier for loc ing, the director.

. 2-. A terminal in pneumatic despatch apjparatus having a passage-way therethrough and a discharge opening and a chamber opposite the discharge opening, a director pivoted in said chamber and projecting into said pas sage-way, a fixed stop, and means on the deflecting end of director in position to be engaged by a carrier and moved so as to engage said fixed stop.

3. A terminal in a pneumatic despatch apparatus having a passage-way for carriers,

with a discharge opening, a director projectrector so as to be normally in an unlocking position, and the carrier with a projection from the head thereof that is adapted to engage said locking-trip and move it to a lock ing position before the head of the carrier engages the director.

4. A terminal in a pneumatic despatch aparatus having a passage-way therethrough ior carriers and a discharge opening, a plu' rality of carriers the deflect-ing end of, a director projecting into said passage-way, a fixed stop, and means pivoted on said director in a position to be engaged by a por tion of said carriers and moved so as to engage said fixed stop.

In witness whereof, I have hereunto affixed my signature in the presence of the witnesses herein named.
