To all whom it may concern.-

Be it known that I, HENRY GAZAILLE, a citizen of Great Britain, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Cash-A Transmitters; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilledl in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to devices for transmitting cash through a pneumatic tube from a salesman to a cashier, and vice versa, in stores or other places of business, of a class in which is employed a tube of uniform diameter, to receive a closely-fitting cash-carrier adapted to traverse it, one end of such tube being open and terminating at the cashiers desk, andits opposite end being practically closed and terminating at a point convenient of access to the salesman, an air-pump or its equivalent being connected with the tube for the purpose of inducing a current of air through the latter in either direction, and a suitable signal being combined with said tube and air-engine, to be operated by the cashier to notify the salesman his change is ready.

A prominent example of the class of trans mitters to which my present improvements .relate is shown in Letters Patent of the United States issued to myself on the 5th day of June, 1883. In the device as thus patented the distance to which the cash box or carrier can be impelled is restricted to a comparatively short range, for the reason that after the box is inserted in the tube and the tube closed against admittance of air repetitions of the motions ofthe pump only end in the box being driven back and forth in the same space, being retracted by the suction as far, or nearly so, as it was driven forward by theprevious stroke of the pump. In my present improvements I employ a case capable of being hermetically sealed, and into this case-I extend one end of the transmitting-tube, said case having a door to permit of insertion of the cash-box, and an air-inlet port governed by a double valve, so arranged that when the cash-box is inserted and in this latter event the construction shown in my patent' is suflicient. considerable distances are to be traversed that the double valve is necessary.

The drawings accompanying this specication represent, in Figure I, a side elevation, and in Figs. 2 and 3 opposite vertical sections, of a device embodying my improvements.

In said drawings, A represents a case which constitutes a receiver, as it may be termed, of my transmitter, this case being of a size and shape to permit the cashbox to be inserted in the tubewhich terminates at one end in said case, a portion of said tubebeing shown at B.

\ D represents an opening in the front of the case A to permit of introduction into the tube BA of the cash-box, while E represents the door of such opening, the said door E being constructed to close tightly against the case to prevent ingress of air.

F represents an air-inlet port in the back wall, vGr, of the case A, this port F being governed by a double valve, H, composed of two ordinary dapper-valves, a b, hinged at top to the Wall G above the port F, and upon opposite sides of the latter, these two valves being held apart at an angle of thirty degrees, more or less, by an actuator, I, erected upon a bar, J, which is a Vthin upright plate sliding in a groove, d, in the bottom of the case, and arranged at rightangles to the longest planes of the two valves. When the actuator I is pushed rearward, the valve a is permitted to open and close automatically,- and the valve bheld open, andvice versa.

The operation of this device is as follows: supposing the salesman being about to send cash to the cashier, and the inner valve, a, being operative, whilethe outer one, b, is open and inactive, the'V door E of the case A is opened and the cash-box inserted by the salesman in the mouth of the tube B, when the It is only when ICO door E is closed. Thesalesman now gives one stroke, for instance, pushes down the pumpplunger of the air-pump connected with the case A, (a portion of the pipe connecting suoli pump with the case being shown at IL) which drives the box a certain distance Within the tube, the valve a closing tightly and preventing escape of air b y Way of the port F. If the distance to which the cash-box is driven by this single stroke of the pump is sufcientto reaeh the cashiers desk, the cashier inserts the box, with the ehungein the open end of the tube near him, and the salesman, by a reverse stroke of the pump. bringsthe cash-box,\vith its change, back to himself, the valve b automatically elos ing` and preventing inrush of air to the case. lf, however, the eashiers desk: is so remote from the salesman that one stroke of the pump Will not drive the cash-box snilicieutly far to reach said desk, the salesman simply lifts the pump-plunger, and again lowers it, thereby driving the caslrbox a corresponding` distance farther ou its journey, the olapperfvalve d opening to admit air and closing to prevent its escape. This allows air to enter the ease and tube, and the return-stroke of' the pump can be made Without bringing bach the oash box, which remains at the point in the' dispatch-tube B to which it was driven by the iirst or direct stroke of said pump. The salesman, if necessary, now gives a third direct stroke to the pump, with the saine :resultsd that is, drives the easlrbox a farther distano-e in the dispatch-tube, and these motions are to be repeated until the box arrives at its destination. When the cashier places the cashl3ox,withll1e change, in his end of the tube, and noties the salesman that his change is ready, the latter first reverses the position of the tufo valves a b by pulling the bar J for- Ward-that is, holds the valvea open and permits the valve b to open and close automatically. The salesman now raises the pumpplunger, which exhausts the air from the tube B before the cash-box, and drives the latter toward the salesman, the valve b in the act automatically closing to maintain the ease A air-tight. Should this single stroke of the plunger be insuflicient to return the cash to the salesman, the latter pushes down the pumpplunger in readiness for a new stroke, the valve b opening automatically, and allowing escape ot air from the case A, as otherwise the cash-box would be driven back by this movement of the pump-plunger. The salesman new lifts the pluim-plunger, and thereby drives the cash-box a corresponding distance nearer to him, and these motions are repeated as long as is necessary.

1. The combination, with a Case or receiver, the dispatclrtu be, and an air-pump connecting with said ease and tube, ot' a valve or valves for admitting entrance of air to the case und dispatel1-tube, and for closing;r the opening by which sneh air enters when the direct stroke of the pump is being made, substantially as explained.

2. In combination, the ease A, with its door E, the dispatelrtube B, air-supply tube K, and double valve a I), arranged and to operate substantially as explained.
