PATENT orries DBENKABZD, OI WEST NEW YORK, NEW JERSEY, ASSIGNOB TO WESTERN 'UKIOH TELEGRAPH COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK PHE'UIATIG DISPA'ICH CARRIER Application filed April 12,

invention relates to pneumatic tube systems or conveyors and has special reference to a system of this kind used in the conveyance of telegraph messages, letters and 5 other like articles. More especially the in- I at these distributing stations the carriers are delivered from the pneumatic tubes and dis-- tributed to other tubes of the system or to some other distributing means. As is well known, in the handling of telegrams and other like messages, each article bears the address to which it. is tobe sent or has distinctive color or has a sticker or other. designation attached 'to it. If opaque carriers are 'used to hold the messages then they have to be removed and the address read or designation noted at thedistributing station before they can beproperly routed from that point. Attempts have been made to overcome the losstof time and the errors occa- *sioned by this manner of routing the carriers and their messages by providing an other- Wise 0 aque' carrier with a transparent win- I dow t ough which the address-or other designation on the'message may be observed.

"However, this necessitates the use of much" care in placing the-message in the carrier so that the designation is properly opposite the window and furthermore the message is Y apt to shift its position during the pa'mge 9 of the message the carrier, so long'as quent station in sitioning the message and a frefurth r loss of time at the distributing station;

The principal object of'the present inven-- tion is tot legrovide a novel form of carrier so construe that, irrespective of the position 1929. Serial No. 354,588.

Figure 9 is a section on the line 99 of Figure 8 showing the carrier closed and hold- 1ng a message. I t

Figure 10 is a section similar to Figure 9 but "showing the carrieropen for the extraction or insertion of a message.

In the "form of the invention shown in Figure 1 the body of the device is made of a single. transparent tubev 10 of Pyralin, celluloid or other suitable transparent material. This body forms, a cylindrical tube Open at both ends but at one end there is provided a piston member 11 of felt or the like of such size as to fit snugly in the pneu matic tube through which the carrier is'to I pass. Riveted to this piston is a cup 12 which receives one end of the tube 10 so that this end is closed and held to the piston 11. At the other end of the tube 10 is a collar 13 preferably made from the same material as the tube and this collar not only acts as a reinforcement for the mouth of the tube but also forms the selector element for use 'in connection with certain automatic carrier dis- I tributing mechanisms in which the distribution is controlled by the width of the collar. Secured to the inner side of the tube 10 is a small substantially semi-circular tubular guide 14 having a perforated plug or stopper .15 adjacent its free end. Through this stopper slides a wire 16 which carries a collar 17, the wire being surrounded by a spring '18 so that it is constantly urged inwardly.

( tube free for the insertion or withdrawal of the message, the tube being afterwards closed by a reversal of this operation.

In the form of the invention shown in Figures 5 to 7 inclusive the body is likewise formed of a transparent tube 22, one end of which is received in a cup 23 secured to a piston 24, a flange 25 being interposed between the cup and pistonto make a closer fit of the carrier in the pneumatic tube. The other or open end is reinforced by a band 26 carrying a felt ring 27. In-this'form the message M is retained in the tube 22 by an elongated loop 28 of spring material having one end secured to the piston 24 as at 252.

In operating this type of message holder the free end'of the loop 28 is grasped and pulled out'which contracts the loop laterally to the position shown in dotted lines in Figure 6 whereuponthe message may be readily removed or a message put in position.

In the form shown in Figures 8 to 10 in clusive the body of the device is formed of two

arcuate tube sections

30 and 31, each extending arcuatel more than 180 and here .shown as extending for about threeuarters of a circle. These sections are neste inside I of each otherand one section is carried by a iston 32while the other section is carried.

y a piston 33, the sections being interlocked so that they will not slide longitudinally on each other. By rotatin these pistons with respect to each other the sectlons may be moved between the position shown in Figure 9 in which the openingsor gaps of the sections do not register and the position shown v in Figure 10 in which such openings or gaps any position wherein such message cannot be read or observed.

It will be observed that by means-of this construction there is no necessity of opening" the carrier to ascertain the destination of the contents when the carrier is relayed from any one tube to any other tube or to any distributing system and thus a mar ed increase in handling speed is effected. Furthermore, this arrangement eliminates the necessity of attaching to the carrier costly indicating devices WhlCh must be adjusted to indicate various destinations.

This carrier will also ellmmate the necesother I sity for providing a large number of groups of variously colored, numbered or lettered carriers, one group being assigned to each possible route which a message or other contents might traverse.

Also the transparent carrier eliminates the possibility of a. message or other contents lying dead in a carrier which is presumably empty, since the entire contents may be seen systems, consisting of a cylindrical tube of transparent material open at both ends, a piston member closing one end of said tube and attached thereto, and article retaining means. at the open opposite end thereof.

4. A message carrier for pneumatic tube systems, consisting of a cylindrical tube of transparent material open, at both ends, a
