Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed May 24., 1905. Serial No. 261,963.

To all whom it may concern.-

Be it known that I, JOHN S. JACQUES, a citizen of the'United States, residin at Dorchester, in the county of Suffolk an State of Massachusetts, have invented new and useful Improvements in Pneumatic-Despatch-Tube Systems, of which the following is a specification.

This invention relates to an im roved pneumatic-despatch-tube system, t e object of the invention being toprovide a simple, cheap, and efficient system whereby carriers containing money or other articles may be moved from one place to another by means of a vacuum which is produced in the tubes of the system, as hereinafter fully described.

The device of my invention is particularly adapted for use in store-service cash-carrier systems.

The invention consists in the combination of an ejector with a system of tubes, as hereinafter described, whereby a vacuum maybe produced in said tube system which, pro erly controlled by devices and mechanism iiereinafter described, causes a carrier inserted at the inlet-orifice of one of said tubes to pass through said tube and be, delivered at the outletorifice of said tube.

The invention further consists in the combination and arrangement of parts set forth in the following specification, and particularly ointed out in the claims thereof.

R erring to the drawings, Figure 1 is a front elevation of my improved despatchtube system, showingthe same in position in relation to the different floors of a building, said building being shown in section and broken away to save s ace in the drawin s. Fig. 2 is an enlarged ont elevation of t e transmission and return tubes of a portion of my system, the same being broken away to save space in the drawin s and shown in connection with a portion a cashiers desk and sales-counter. Fig. 3 is an underneath plan of the transmission terminal valve for the -in-.

.Fig. 8 I

sion-sprinlg In the drawings, referring to Figs. 1, 2, and 3, is the wall of a building; 6, 7, and 8, the different floors thereof. 10 is a boiler of any suitable design and construction, and 11 a steam-pipe leadin from said boiler to the stand-pipe 12. T e stand-pipe 12 is connected to the inlet-orifice 13 of an ejector 14. The outlet-orifice 15 of said ejector is connected by a pipe 16 to an exhaust-head 17. A throttle-valve 18 is inserted in the pipes connecting the boiler 10 With'the ejector 14, and said throttle-Valve is opened or closed automatically to supply steam to the ejector 14 by mechanism hereinafter described, said mechanism being operated to open or close said throttle-valve, according as the vacuum increases or diminishes in the vacuum tank or reservoir 19. connected by a pipe 20 to an orifice 21, provided in the ejector 14 intermediate the inlet and outlet orifices thereof, and said vacuum-tank is connected by pipes 22 22 to the different systems of pneumatic despatch tubes 23 23. Each of these systems is substantially a-duplicate of the other, and a descri tion of one will therefore suflice for all of sai systems. By reference to Figs. 2 and 3 it will be seen that the pipe 22 is connected to a transmission-tube 24, which at its upper end is rovided with a transmission-terminal 25 an at its lower end is fastened to. a U- sha ed connection 26. The return-tube 27 is a so fastened to said U-shaped connection. The transmission tube 24 has an inlet-orifice 28 and an outlet-orifice 29. The inlet-orifice 28 is provided with a terminal valve 30, pivoted at. 31 to ears 32, formed upon the U-sha ed connection 26. The valve may be hel open by a catch-lea sales-counter 36. An armature 37 is fast to the catch-lever 33 and forms, in effect, a single piece therewith, and is attracted by an electroma net. 38 in electric circuit with wires 39 39 an '40, 41, and 42 and battery 43. The "wires 39 and terminate in contact.- plates' 44 and 45, respectively, and these plates are broughtinto contact with each other by the terminal valve 46, which is adapted to close the outlet-orifice 29 of the transmission-tube 24 and is pivoted at 47 to This vacuum-tank 19 is .ver 33, pivoted at 34 to a bracket 35, fast to ICC an ear formed upon the under side of the transmission-terminal 25. A spiral compres- 48 holdsjthe catoh-lever'33 normally in t e position illustrated iniFig. 2.

' The transmission inlet terminal valveis V illustrated in detail in Fig. 3, in which it will be seen that the valve 30 is pivoted to the stud 31 midway between the ears 32 32 and is held normally in the position illustrated in Fig. 2 or in its closed position by spiral springs 49 49, which are fastened at one end to,said valve and at the other ends thereof, respectively, to the cars 32 32. The returntube 27 is provided at its upper end with an inlet-orifice 50 and at its lower end with an outlet-orifice 5]. The inlet-orifice 50 is closed by means of a terminal valve 52, pivoted at 53 to ears formed upon a collar 54, fast to the upper end of the return-tube 27. When said terminal valve 52 is in the position illustrated in dotted lines, Fig. 2, it engages a catch-lever 55, pivoted at 56 to a bracket 57, fast to the return-tube 27. An armature 58 is attracted by an electromagnet 59, which is in electric circuit with wires 60 60 and 6141 42 and battery 43, said wires 60 and 61 terminating in contact- plates 62 and 63, respectively. The circuit is completed by the terminal valve 64, which when it swings on its pivot presses the plate 63 against the plate 62, said terminal valve 64 being the valve which closes the outlet-orifice 51 of the return-tube 27. A spring 48 holds the leverpiston 96, operated by the pressure of water entering througii the pipe 68 into the valvechamber 97 con ained in said piston 96. The piston-valve 98 is constructed to move longitudinally of the valve-chamber 97 and is connected by a valve-rod 99 to a lever 100, pivoted at 101 to a bracket 102, fast to a tubular piston-rod 103, which inturn is fastened. to the piston 96. The lever 100 is pivotallyconnected at 104 to a lever 105, pivoted at .106 to a bracket 107, fast to the casing 66. 3 A rod 108 is pivotally connected at 109 'to the lever 105 and is connected at its lower end to a. suitably-weighted diaphragm 67. The piston 96 is connected by a tubular piston-rod 110 at its lower end to a lever 70, which in turn is connected by a rod 71 to an arm 72. Y The arm 72 opens and closes, ac cording to the direction in which it is rocked,

the throttleor shut-off valve 18. Ports 111 and 112, provided in the piston 96, lead, respectively, to the upper and lower ends of the cylinder 69 from the valve-chamber 97.

. The 0 eration of the regulating device hereinbe ore specifically described is as follows Water-enters through the pipe 68-into the valve-chamberv 97, and as the pressure in the vacuum tank 19 varies the variation is .communicated to the interior of the casing 66 through the pipe and the diaphragm um in the'tan 67 is moved upwardly or downwardly, in accordance with the variation of pressure in said tank. This upward and downward motion of the diaphragm 67 iscommunicated by the rod 108 to the lever 105'and through the lever 105 to the lever 100, thus moving the valve-rod 99 upwardly or downwardly and allowing the water to enter from the pipe 68 through the valve -chamber 97 and through either one of the ports 111 or 112, as the case may be, thus allowing the water to enter the upper or lower end of the cylinder 69 and drive the piston 96 downwardly or upwardly therein, respectively. The piston 96 being connected by the piston-rod 110 to the lever 70, any motion of the piston will be communicated to the lever and through the rod 71 to the arm 72, which opens and closes, according to the direction in which it is rocked, the throttle-valve 18, as hereinbefore described, so that when the vacuum in the tank 19 is diminished by the use of the carrier system the diaphragm 67 will be actuated by the decrease of the vacuum in the tank 19 to admit water through the pipe 68 to actuate the piston in the cylinder 69 .and to rock the lever 70 to open the throttlevalve 18. When the vacuum is increased in the tank 19 to the desired amount, the. pressure .upon the diaphragm 67 will act to reverse the motion of the lever 70 and to close the throttle 18 and shut off the steam from the ejector 14. r

The ejector 14 is illustrated in enlarged section in Fig. 8, it being understood that any of the well-known forms of siphon ejectors may be used in order to produce vacuum ina carrier system, acting upon the general well-known principle of a nozzle 73, Fig. 8, arranged to discharge steam or compressed air, as the case may be, inside a casing 7 4 and at the entrance to a funnel-shaped pipe 75, leading to the outlet-orifice 15, the intermediatorifiee 21 being located in such position as to communicate with the interior of the casing 74, so that when the steam or compressed air discharges from the nozzle 73 into the funnelshaped pipe it will suck or draw the air into the interior of the casing 74 through the intermediate orifice 21 from the vacuum-pipe 20 and vacuum tank or reservoir 19. A check-valve 7 6 is inserted in the connecting-pipe 20 between the vacuumtank 19 and the ejector 14, so that when the throttle-valve 18 is closed, as hereinbefore described, air will not enter the tank. 19, through the pi e 16 and diminish the'vacuand in the tubes of. the carrier system attached thereto by the pipes 22 22.

The operation of the form of my invention hereinbefore specifically described and illustrated in Figs. 1 to 4, inclusive, is as follows: A carrier 77, Fig. 7, 6f suitable size and form is inserted by thesalesman in the transmission-tube 24 by first opening the valve 30 and moving the same into the position illustrated in dotted lines, Fig. 2, so that the catch-lever 33 holds the same open while inserting said carrier, it being assumed that the tubes of the system are supplied with the proper vacuum. Said carrier will be drawn upwardly through the transmission-tube 24 and will pass around the curved portion of the transmission-terminal 25, passing outwardly through the outlet-orifice 29, opening the valve 46, and falling into a suitable receptacle placed upon the cashiers desk 78, and as the carrier passes out of the orifice 29 and rocks the terminal valve 46 the insulated outer end of said valve presses upon. the contact-plate 44 and presses it into contact with the terminal plate 45, thus completing the circuit and energizing the electromagnet 38, which then draws the armature 37 downwardly, together with the catch-lever 33, and releases the inlet-terminal valve 30, so that the spring 49 may close said valve. It will therefore be seen that when the carrier is delivered at the outlet end of the transmission-tube the terminal valve at the outlet end of said tube completesthe circuit and closes the terminal valve at the inlet end of said transmission-tube. The operation of the return-tube and its terminal valves is substantially the same as hereinbefore described in relation to the transmission-tube and its terminal valves. made the proper change inserts the carrier 77 in the upper end of the return-tube'27 by opening the inlet-terminal valve 52, moving the same from the position illustrated in full lines, Fig. 2, to that shown in dotted lines therein, the same being held in the position shown in dotted lines by engagement with a catch-lever 55, and said catch-lever is detached from engagement with the terminal valve 52 by the circuit being completed through the wires 60 and 61. As the carrier is discharged through the outlet-orifice 51 and upon the sales-counter 36 as said carrier passes through the outlet-orifice 51, the valve 64 will be 0 ened thereb and its insulated outer end W1 1 contact wit the plate 63, moving the same into contact with the terminal 62 and completing the circuit toene'rgize the electromagnet 59, drawing the armature 58 downwardly and rocking the catch-lever 55 to disengage the terminal valve 52. M It will thus be seen that as the carrier is placed in the transmission-tube or in the return-tube and'deliveredto the cashiers desk or salescounter, respectively, the tube through which the carrier is passing will be 0 en at the rear of'the carrier and closed in advance thereof until such time as the carrier passes out of the outlet-orifice of said tube, when electric connection will be made and the tube throu h which the carrier has just passed closed at its inlet-orifice. Each of the systems illustrated in Fig. 1 operates in the manner hereinbefore The cashier havingminal 25 is illustrated in Fig. 5, in which a curved slotted partition 79, guides the carrier around the curved terminal 25 and at the same time allows the air to pass through the slots 80 in said partition. The interior construction of a portion of the U-shaped terminal 26 is illustrated in Fig. 7, in which a partition 81 is provided with slots 82, so that the carrier is prevented by said partition from passing around the curved portion of the U of said partition; but the transmission and return tubes 24 and 27, respectively, are connected one to the other through said slots 82 and through the curved portion of said U- shaped connection.
