SPECIFICATION forming part of Letters Patent N0. 564,427, dated July 21, 1896.

Application filed August 5, 1895. Serial No. 558,236. (No model.)

At the cashiers or central station there are as many send-offs Gr as there are outlying or salesmens stations, each send-oft consisting of a short branch pipe or tube g, leading into the main line, as shown in Fig. 4f, and at theouter end beveled from opposite sides to the middle at equal angles at g g', say of about forty-iive degrees, to said sides, a box g2, formed in halves g3 g3 and having iiaps g4 g4, which, when the halves of said box are closed against each other, as shown at the left of said Fig. 4, rest upon and it said bevels or angles g g and close the outer end of said branch g, and springs g5 g5, (represented as leaf-springs,) ca ch secured at one end to one of said halves g3 g3 and at the other end to the side of said branch g, these springs normally holding the halves of the box together. The bottom g6 g of each halt of the box g2 is inclined so that these bottoms form the inclined faces of a hollow wedge. At each salesmans station there is a send-off G G2 G3 precisely like the send-off G, above described, connected by a branch c4 c5 cG to the main line.

The carrier F is well known, being in common use, and is a hollow metallic cylinder, having at its ends concentric supporting-circles f f of felt or similar soft material, larger than the body of the carrier, to lessen wear of the tube or line C, and having at the rear end a conical flap f2 of leather, to be expanded by the pressure of the blast from the blower to fill the tube and prevent the air from leaking through the space between the carrier and the walls of the tube.

The carrier F is pushed into the box g2 of a send-ofi", crowding apart the halves of said box, as shown at the right in Fig. 4, and is drawn by the current of air, assisted in some cases by the weight of said carrier, into the main line. When a carrier is placed in any salesmans send-off, said carrier is immediately propelled by the air-current to the cashiers station and there discharged into the receiver E, no switches being required on the line in, that is, the line from the outlying stations to the central station.

In order that the cashier may be able to send a carrier to a particular salesman, the junction of each siding c c2 c3 is provided with a switch H H2 H3, each comprising, Fig. 5, a iap or gate 7L, capable of closing either the main line or lthe entrance to the siding trance to the siding c' c2 c3 is provided with a recess c7,wh1ch normally receives said finger.

Each iap moves easily and is held in either position by the air-blast, the siding and the main line having the same capacity or crosssection.

The pivot 7L of the iap 7L turns with said i'lap and has rigidly secured to it an arm or lever h3, which carries the armature m of an electromagnet M, there being such a magnet for each switch H H2 H3, and each magnet being connected by a separate conductingwire L L2 L3 to a battery B or generator of electricity, whilea single return-wireL serves for all said magnets. In each conductingwire L L2 L3 is arranged a normally open circuit closer N N2 N8, each consisting of a pair of sprin gs a n', insulated at n2 n3 from each other and from the send-oit, but supported on the stationary part of the latter in such a manner that in opening the box g2 one of the halves of said box strikes the spring n and pushes it against the spring n' of the same pair, closing the circuit through the corresponding electromagnet and switching the siding adjacent to said magnet into connection with the main line. It is only necessary to designate the carrier used at a particular salesmans station and the corresponding send-oit at the cashiers station by the same number or other mark to make sure that each salesman will receive back his own carrier unless through inexcusable carelessness on the part of the cashier. To make it certain that the flap h shall not be accidentally turned from its proper position, the pivot h' of said flap is provided outside of the tube with a projection h4, having two oppositely beveled surfaces, and a spring-pawl h5 is ar ranged to engage said projection and to hold said lap in either of its positions, the free end of said pawl h5 having a tooth with oppositely-beveled surfaces hh?, adapted to ride over said projection when a considerable amount of force is applied to said iiap, but to hold said flap from turning against the application of any ordinary force.

The described improvement is of course applicable to any pneumatic-carrier system connecting a central station with outlying stations.

I claim as my invention in a pneumaticdespatch-tube systeml. The combination of amain line of tubing connecting a central station with an ontlying station, a siding or branch at said outlying station, and a mechanical switch normally disconnecting the main line and said siding, an electromagnet having an armature movable with said switch, an electric circuit including said magnet, a normally open circuit-closer at said central station to close said circuit and to operate said switch, to make the corresponding siding continuous with said main line, and a send-ott box normally closed and adapted when opened to close said circuit-closer, as and for the purpose specified.
