JAMES T. COWLEY, OF LOWELL, MASSACHUSETTS, ASSIGNOR TO THE LAMSON CONSOLIDATED STORE SERVICE COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY.

TERMINAL FOR PN EU MATlC-DE-SPATCH-TU BE APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 685,824, dated November 5, 1901. Application filed August 11,1900- Serial No. 26,584. (No model.)

To all whom it may concern.-

Be it known that I, JAMES T. COWLEY, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Terminals for Pneumatic Despatch Tube Apparatus, of which the following is a specification.

My invention relates to an improved terminal for pneumatic-despatch-tube apparatus.

One object of my invention is to regulate the air-pressure in the apparatus.

Another object is to provide an improved terminal which is adapted for connection with transmissiontubes comingin either direction.

A further object is to decrease the friction between the carrier and the tube as the carrier passes from the terminal.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure l is a side elevation, partly in section, of a terminal and cooperating parts embodying my invention. Fig. 2 is a similar view showing the transmitting-tube coming from the opposite direction from that shown in Fig. 1. Fig. 3 isa detail sectional view of the terminal in which carriers are received from the transmitting-tube and pass to the delivery-chute in front of the cashier. Fig. 4 is a detail view showing mechanism for regulating the wind-gate. Fig. 5 is a detail front View showing a screen for discharging onto the cashiers desk coin or other articles which may accidentally leave thecarrier during transmission.

Like letters of reference refer to like parts throughout the several views.

The transmission-tube C is clamped by the upper bolts T to the terminal A, composed of two sections X and X, to the latter of which is clamped the delivery-chute 13 by the lower bolts T and into which the carriers WV are received and pass to the cashier. Atthe entrance of the section X of the terminal A is pivoted at E the valve D and normally held closed by atmospheric pressure due to the partial vacuum formed by the suction through the return suction tube F. This valve opens under the impactof the carriers, which pass over the mouth of the tube F at right angles thereto, and after they have passed the valve is closed by the suction of the air through said tube F, which leads from the terminal A transversely to the line of travel of the carriers, while the carriers are guided to the chute B by the section X, which thus formsa guideway for the carriers to said chute B. On the lower end of the returntube F is secured a casting G, fast to the desk H, and on the front end of said casting is located a pivoted door J, normally closed by the suction of the air passing down through the pipes F and I. Within this casting is located the screen K, which rests at its upper part K against the under side of the tube F and the lower part bears against the pin K This screen is inserted by pressing the upper part into the position shown in Fig. 1 and then springing the lower part over the pin K and the screen is held in this manner, as shown in Fig. 1. This screen directs any coins or other articles which may have accidentally left the carrier during transmission onto the desk Hupon the opening ofthedoorJ. Located across the casting G is a valve L, secured on the shaft M, which extends across the casting and is jonrnaled thereon, and one end is provided with a nut M and a flat spring M, and upon tightening up the nut M the friction thus formed holds the valve in the position at which it is set. On the other end of the shaft M is secured the handle N, provided with a'pin R, which is adapted to contact with a shoulder Q on the plate Q when turned to its open position, as shown in dotted lines, Fig. 1. This plate Q is provided with a slot P and a set-screw Q, and by loosening said screw and shifting the plate Q the position of the shoulder Q may be changed, and upon tightening the screw Q the valve will be opened to the desired point-as, for

instance, on a long line the valve would be opened more than on a short line-and also in case another line is added to the system the plate is adjusted so that the valve may be opened further in order to allow the proper volume of air to transmit the carrier.

said section is provided with asuitable open-' ing 0, closed by a cap P, clamped in its position by the bolts T which also clamp the upper end of the tube F. A sleeve S is located between said openings 0 O in the chamber X of the section X and is provided with an opening S, through which air is drawn into- The the chamber X and the return-tube F. parts shown in Fig. 2 are substantially the same as those shown in Fig. l, excepting the arrangement, and that consists in locating the terminal A in a reversed position to that shown in Fig. 1, so asto connect the transmission-tubes coming in the direction opposite to that indicated in Fig. 1. By this arrangement all the tubes entering the cashiers station from either direction pass into the chutes B in front of the cashiers who are stationed at the left of the desk H. In the terminal A (shown in Fig. 2) the cap P is on the under side of the terminal and the opening 0 on the top of the terminal, whereas in Fig. 1 the opening 0 is on the under side of the terminal and the cap P is on the top side of the terminal. The chute B is held in position by the clamp U, secured by bolts on the returntube F and said delivery-chute B.

It frequently happens that a number of carriers are in the terminal at the sametime, and the valve D, allowing the discharge of the carriers, is held open for some time. When this occurs, the rear carriers are held back by the suction of the air passing in through the open valve and down through the tube F, and the 1 carriers are stopped owing to this suction. \Vh'en this happens and the valve D-is held open, it is necessary to shut off the air through the tube F. in order that the carrier may be allowed to deliver. This is accomplished by closing the valve L, and after the carrier is delivered the valve L is opened again. The

pin R on the handle N will regulate the dis-' tance the valve will open, as previously described. The chamber G islocatedon the top of the desk H ineasy reach of the operator, so that the valve L will be readily closedand also so that the adjustment maybeeasy and convenient, and the location of this chamber on top of the desk guides the coin or other articles which may have been'dropped from the carrier within reach ofthe cashier.

The openings 0 -O' on the opposite sides of the terminal-section X are arranged as shown -in order that the tube F may be connected to either side, as desired, and the connection may be made by thewprkmau when the sys- -ten1 is installed and the tube'F connected with either opening, as desired, and the cap inserted in the unused opening, thus simplif yin g the arran gemen t by requiring less parts to the device and requiring but one pattern for the terminal without regard to the connection with tubes coming from either direction. The openings S in'the sleeve S vary, as shown in Fig.- 3, for the following reason: The air passing through the terminal X and down through the tube F tends to direct the carrier toward the tube F. In order to overcome this tendency, the openings S are larger at the upper side than they are at the lower side in order that a greater volume of air may pass through the upper part of the openings than through the lower part, and

the effect of this construction is to. lift the 'theopenings S into the section X.

Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is-
