Application filed July 22, 1914. Serial No. 852,526.

To all whom it may concern:

Be it known that-I, LEOPOLD Lonnnnnnne, mechanical engineer, ELSlllJJQCt of the King of Prussia, and residing at Rua da Al-J fandga, Rio de Jane1ro, Brazil, have 111-1 vented certain new and useful Improve" ments in Apparatus for. Tubular Transferring Systems, ofwhich the following is 'a specification.

This invention relates to apparatus adaptable for use as a sender, receiver, or as a passage apparatus (intermediate station) for tubular transferring systems. The apparatus is characterized particularly by ex-- tremely great simplicity of the arrangement and manipulation, and'consists essentially of a rotary gate, or valve device by the rotation of which the system is tightly closed from the atmosphere and the introduction and removal of the cylinders or boxes is still made possible.

Two examples of construction of theap paratus are illustrated in the accompanying drawings, in which i Figure 1 is a vertical section through one type of apparatus. Fig. 2 is a ver-. tical section at right angles of Fig.1, in

which the gate is closed from the communicating pipe. Fig. 3 shows the gate in a position open to the communicating pipe with a box admitted. The illustrated apparatus shows a receiving device or in termediate station, but it can be applied conversely and with suitable alteration as a sending apparatus, and Fig. 4 is a .Vertical section through the middle of the apparatus according to another form of construction with valve device closed, and Fig. 5 is a section similar to Fig. 1 but the valve device in the discharging position.

Referring to the drawings the gate con sists of a rotary drum 1, in which achamber 2 is formed which servesfor the reception of the box or cylinder 3. Thechamber 2 of the drum is closed at one end and open at the other. The drum is arranged inside a completely inclosed casing 41 kept under pressure or under vacuum, to which casing at the top and below, the'tubes for bringing in and discharging the box, are con.- nected. The joint for keeping the gate drum 1 tight from theatmosphere' is made inside the casingt by a shoe 5 lying tightly upon the outside surface of the drum,? and,

itself is tightly connected to the pipe pass ing through the bottom of the casing. The

flange and the wallof the drum are ground into one another or otherW1se' made with ;a tight joint. In order to be able to press the flange against the drum it is connected to a tubular piece 7. and to a flange 9 tightened by nuts.

By tightening up the nuts 8 the flange 5 can at any time be pressed against the drum 1. For this purpose the tubular piece 'Tforms an adjustable joint in a stuffingbox 9.

In the position illustrated in Fig. 1, the

gate chamber 2 is shutoff from the interior of the casing 41: by the bottom of this chamjber, which is now at the top, but'it is in connection with the pipe and the receiving outlet 6. "If, now a box passes in through the pipe 10 and falls into the receiving pipe -11 thereunder, which can be indicated through inspection openings 12 the drum 1 iis. turned in the direction of the arrow 14 through an angle of 180 degrees by means of the crank handle 13 connected to it, until it takes up the position shown in Fig. 3, so that the box 3 can fall into the gate chamber 2. If, now the gate is again turned back to the position according to Fig. 1 by .means of the handle, then the box 3 falls out below, as Fig. 4 shows, and can in this. iway be removed if the lower pipe 6 is opened. If, now, several boxes are passed 1 "one upon the other, an apparatus is provided in. order to allow always only one box to pass the gate, since this is suitably designed of such a size only to take one box. For this purpose'adouble-armed lever 15 is mounted in the casing 4 and the nose 16 of this lever can under the operation of a s rin 17 en a e throu h an o enin in p a a: a:

the side of the receiving pipe 11. A'pro- .jection- 'or. stop 18, arranged on the gate drum 1 beyond the reach of the flange 5,

operates inthe position shown in Fig. 1 an extension of the lever 15 in such a manner that the nose 16 remains outside the receiving pipe 11. In thisposition of the lever .15 the. boxescan pass the openings'into which the nose can pass into the pipe, but

now, if the drum 1 is turned throughan angle of 180 degreeslintothe position shown in Fig. 3, this nose: engages from the side into the receiving pipe lland retains the second box 3 which lies above the lowermost box 3' .(see Figs. 2 and so that only the sition shown in Figs. 1 and 4, the lever 15 is pushed back at the same time by the stop 18 until the nose 16 passes out of the receiving pipe 11 and the box 3 is free to fall down. In this way it comes about that always only a single box can pass into the gate chamber while the box above this one is held fast.

The gate drum 1 can be formed differently. In the construction illustrated by Figs. 1-3 the gate drum is mounted upon a horizontally placed shaft and there is only one chamber which has its opening turned about the horizontal axis to the top or to the bottom.

With the form of construction illustrated by Figs. 4; and 5 the section pipe 2* is fixed in the interior of the rotatable valve 1 and arranged as a continuation of the receiving pipe. The fixed section pipe 2 is surrounded by the circular valve 1 which has a suitable opening for passing through the boxes. The position of this valve in Fig. 4:

is to receive the box, whereas the Fig. 5 shows the discharging position of the valve, the latter being turned through 180 degrees. The advantage of this construction is, that the box is not turned by its way through the valve but falls out in the same position as arrived.

-' A jointing shoe is pressed against the outer surface of the circular valve similar to the form'of construction illustrated by Figs. '1'3. Having now particularly described and ascertained the nature of my said invention,

and in what manner the same is to be per formed, I declare that what I claim is':

1. In a cylinder transferring device, the combination of a casing having pipes leading from its upper and lower ends and forming cylinder passages, a receiving pipe disposed in the casing with its upper open end below the upper casing pipe to receive cylinders therefrom, a rotary transfer drum mounted at the lower end of the receiving pipe and having a diametrical chamber closed at one end and adapted to register with the receiving pipe, and a tubular member below said drum, with which the said drum chamber is also adapted to communicate, communicating at its lower end with the lower casing pipe.

2. In a cylinder transferring device, the combination-of a casing having pipes leading from its upper and lower ends and forming cylinder passages, a receiving pipe disposed in the casing and with its upper open end below the upper casing pipe to receive several cylinders therefrom in superosed relation a rotar transfer drum .1 7
