10 being accidentally left in the tube or the slips being crumped or wrinkled or otherwise damaged to make the indicia thereon hard to read.

This invention also consists'in certain other features ofconstruction and in the'combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

erence will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the improved tube.

Fig. 2 is a view showing the parts in a different position to show the slots for-receiving a part of the sales slip.

Fig. 3 is a view similar to Fig. 2, but showing the parts ina position to show the registering openings for permitting money or the like to be placed'in the tube.

Fig. 4 is a section on line 4-4: of Fig. 1.

Fig. 5 isfa view of the outer or transparent part with the end portions attached thereto.

Fig. 6 is a view of the inner or metal tubewhich fits in part connected thereto.

Fig. 7 is an elevation of the entire device showing the parts inposition where one slot engages another.

Fig. 8 is a section on line 8-8 of Fig? 2. Fig. 9 is a section on line 99 of Fig. 3. Fig. 10 is a section on line 10 of Fig. 1. In these drawings, the numeral 1 indicates the inner tube formed of metal and having an opening 2 therein and the numeral 3 indicates the transparent outer tube which is formed with the opening 4 which is formed with the narrow extensions 4 at its ends. The inner tube 1 is formed with a hollow rib 5 which In describing the invention in detail, refis extended inwardly and formed with a slot which opensout through the side of the tube for receiving a part of a sales slip A or other sheet shown in dotted lines in Fig. 8. This rib also acts as reinforcing means for the 5' metal tube and the extensions 4 of the opening 4 covers this slot when the parts are in a certain position, and as shown in Fig. 3 so as to facilitate the entrance of a part'of in the slot.

The openings 2 and 4 are of substantially the same size so that they will permit money or the like to be placed in or removed from the device when they are in registering position or nearly so, as shown in Fig. 3. The ends of the inner tube 1 are closed asshown in Fig. 4, and caps 6 and 7 fit over the ends of both tubes and the tubes are held slightly spaced apart by the end members 8 so that theslip or sheet A can fit between them and after a part of the slip is placed. in the slot with the parts in position as shown in Fig. 2, a turning movement of one tube relative to the other will wind the slip on the inner tube and under the outer tube, and as this outer tube is formed of transparent material the printing or other matter on'the slip will be visible therethrough.

End pieces 9, formed of felt or the like, to snugly fit the conduits of the pneumatic system, are connected to the caps 6 and 7 'by the bolts or screws 10 and one of these end pieces is connected to one end ofthe inner tube 1 by the bolts as shown in Fig. 4:, but the other end is simply connected to the other end of the tube by a central bolt 11 so that said other end piece is pivotally connected to said end of the inner tube.

the slip The corresponding end of the outer tube B is connected to the last-mentioned end piece or to the cap 6, so that it will rotate when this end piece is rotated so that by holding one of the end pieces stationary and turning the other, one piece will rotate relaformed with the recesses 12 for receiving the checks and should they tirely covered which will make it difiicult to remove the slip.

Fig. 10 shows the parts with the stops in engagement and one end of the slip exposed. A leather washer 17 fits between one of the end pieces and the cap 6 for increasing the suction action when the tube is placed in the conduit.

Thus it will be seen that it is simply necessary to turn the parts to the positions they so occupy in Fig. 2 and then insert part of the sales slip or other message carrying sheet into the slot and then by turning the parts, the slip will be wrapped around the inner tube and under the outer tube as shown in Fig. 10

and if money or other matter is to be transported by the device, the money or other object is placed in the device when the openings come opposite each other as shown in Fig. 3. Asgwill be seen from Fig. 10, when the stops 15 and 16 are in engagement with each other, the openings will be out of register, 80 that the money will be held in the device and a slip will be placed between the two tubes and one end partly projected.

The device is then placed in a conduit in the usual manner, but when it reaches the place for which it is meant, the operator at this place can readily read the matter on the slip so thatno time is lost in sending the tube to.

- i the erson for which it is intended.

T e felt end pieces act as guides as well as bumpers, as the carrier leaves the pneumatic tube and falls in the receiver and if desired arrows may be placed on the flanges of the caps 6 and 7 to indicate the direction of turnin of the parts to wind the message into the tube carrier.

This device also enables the operators .to more quickly see the si atures of the sales looking for fraudulent purchasers the detectives could stand at the place where the tubes come throu h and quic 1y glance at the handwriting an check to see if there is any handwriting they are looking for and the could quickly go to the department from w ich the tube was sent before the purchaserbecomes nervous due to an delay.

, s it is now the detectives must wait unml til the tubes are relayed to theauthorizers and sort through the duplicate O. K.d sales checks going to one girl and then another looking at the handwriting. By the timeit is foundenough time has elapsed to allow the purchaser to receive the O. K.d stub and be on her way before the arrival of the de tective in the department.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily a parent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended clalms.

Having thus described our invention, what we claim as new is 1. A carrier tube for a pneumatic tube system comprising inner and outer cylinders having openings therein, the outer c linder being formed of trans arent materia rings placed between the end portions of the cylinders for slightly spacing them apart, means for rotating one cylinder in relation to the other, and means for attaching a part of a sales slip or the like to the inner cylinder whereby the slip will be wrapped on the inner cylinder and under the outer cylinder, when one cylinderis rotated with respect to the other.

2. A carrier tube for a pneumatic tube system comprising inner and outer cylinders having openings therein, the outer cylinder being formed of transparent material, means for rotating one cylinder in relation to the other, means for attaching a part of a sales slip or the like to the inner cylinder whereby the slip will be wrapped on the inner cylinder and under the outer cylinder, when one cylinder is rotatedwith respect to the other, such means comprising an internal rib formed. on the. inner cylinder and providing a slot extending outwardly for receiving a part of the slip.

3. A carrier tube for a pneumatic tube system comprising inner and outer cylinders having openings therein for permitting access into theinner cylinder,the outer cylinder being" formedof transparent material, end pieces, one of which is connected to the inner cylinder and the other to the outer cylinder, said end pieces being formed of felt or the like andof greater diameter than the cylinders, spacer ri 'laced between the end portions of the cy ind ers for slightly spacing them apart, and means on the inner cylinder for detachabl' receiving an endof a sli or sheet whereby said slip or sheet will e wrapped around the inner cylin er under the outer cylinder when one cylin er isrotating with respect to the other.

4. A carrier. tube for a pneumatictube system comprising inner and outer cylinders having openings therein for permitting access into the inner cylinder, the outer cylinder beingformed of transparent material, endpieces, one of which is connected to the inner cylinder and the other to the outer.

cylinder, said end pieces being formed of felt or-th'e like and greater-diameter than the tures.
