srncrrrcacrron forming part of Letters Patent no. 657,886, dated September 11, 1900.
Application filed February 1900. Serial No. 4,806. (No model.)
To all whom it may concern.-
Be it known that I, ALBERT W. PEARSALL, a citizen of the United States, residing at Manhattan borough, New York city, in the county 5 and State of New York, have invented new and useful Improvements in Pneumatic-Despatch-Tube Systems, of which the following is a specification.
This invention relates to receiving-termi- IO nals such as can be used when a partial vacuum or, as it is popularly called, a suction is employed for transmitting a carrier.
By means of this invention a single form of terminal can be made to reliably receive and deliver the carrier coming from tubes suspended, placed, or erected in the various ways common in practice.
The invention is set forth in the following specification and claim, and illustrated in the annexed drawings, in which Figure 1 shows a so-called upward discharge-terminal or one in which the carrier is propelled upward through the tube and in being discharged therefrom travels about a curve or is thrown downward. Fig. 2 shows the same terminal reversed or turned upside down for a so-called downward discharge. Fig. 3 shows a horizontal discharge-tube.
Say, for example, a tube is running along the ceiling of the floor below the one on which the discharge takes place. Such tube when coming to the terminal would be turned upward, as shown by tube a in Fig. 1. Should the conditions be reversed-as, for example,
5 that the discharge should be required on the floor below the one just mentionedthe tube would end or be turned downward, as shown by tube or chute a, Fig. 2. A tube discharging horizontally is shown at a Fig. 3.
The terminal is shown at b and has an outwardly-opening valve 0, and a vacuum or power chamber is shown at d, made to surround the terminal. The wall portion or sieve for separating the terminal and powerchamber has the perforations e, and the power or suction is generated through tube f. The perforations when made sufficiently small will prevent the passage of change or contents if a carrier should have spilled or ac cidentally opened in transit. Diamond or lozenge shaped openings have been found easy to construct and readily placed close to gether. These openings being close to valve 0 the suction will force the carrier up to the valve, so that the latter opens as the carrier g, Fig. 1, comes to emerge.
This terminal, as seen, can be arranged or adapted to receive and discharge carriers coming from various directions or to connect with tubes a ct 61/ running in various direc- 6o tions. The air-current which impels the carrier is brought near to the valve or carrier discharge 0 before said current changes or branches 0%. The number of openings e is such that the areas of the openings at least 65 equal the area or cross-section of the tube. Said openings and chamber d being arranged annularly or so as to surround the terminal the carrier is not sucked to one side or laterally as it reaches the point of delivery. As the carrier is thus not caused to stick to or rub hard against a side of the terminal, such carrier readily runs or travels through the valve 0.
At the outside of valve 0 can be applied any suitable receiver or guideway for receiving the carrier as it emerges from valve 0.
. What I claim as new, and desire to secure by Letters Patent, is-
In a suction pneumatic-carrier system or tube apparatus,the combination with a terminal having an outwardly-opening valve across its delivery end, of a vacuum or power chamber surrounding said terminal and comm unicating therewith through diamond shaped perforations located in the wall of said terminal close to and surrounding said valve, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing 0 witnesses.
ALBERT w. PEARSALL.
