TRAVELING CONVEYER.

` Application iled .Tune 30, 1924. Serial No. 723,179.

This invention relates to improvements in traveling conveyers, the main object being to produce a simple and inexpensive means for holding and releasing the articles carrled by the conveyer. More specifically stated,

an object of the invention is to provlde a device of this kind including a holder for the articles to be carried, a closure adapted to retain the articles in the holder, and a slmple operating means whereby one of the parts is moved relative to the other so as to open and close the holder. u

In the preferred form of the invention, the holder and its closure member are rlgidly connected to difl'erent portions of a flexible traveling support, and this support 1s bent to open and close the holder. A series of the holders may be connected to different portions of the traveling support, and 1nstead of using separate fastening means to attach the closure members, the structure can be simplified by providing each holder with an extended closure member adapted to overlap and form a closure for the next adjacent holder. 0

With the foregoing and other objects in view, the invention comprises the novel con; struction, combination and arrangement or parts hereinafter more specifically described and illustrated in the accompanylng drawings wherein is shown the preferred embod1- ment of the invention. However, it 1s to be understood that the invention comprehends changes, variations and modifications within the scope of the claims hereunto appended.

Fig. I is a side elevation, partly 1n s ection, illustrating avbottle carrier embodying the features of this invention.

Fig. II is a. fragmentary View illustrating `a guiding device whereby the traveling chain is bent to receive the bottles.

Fig. III is a fragmentary view showing a guiding device whereby the traveling chain is bent to discharge the bottles.

Fig. IV is an enlarged section showing one of the bottle holders secured to a chain link, and a closure member extending downwardly from one side of the bottle holder.

Fig. V is a front elevation of one of the bottle holders, showing portions of the traveling chains secured to' the ends of the bottle holder.

To illustrate one of the uses of the invention, I have shown a machine known as a bottle-soaker comprising an endless bottle carrier traveling in a tortuous course through a tank A provided with partitions 1 which divide it into several compartments. EachA compartment contains a liquid as suggested at the right side of Fig. I, and the bottles are carrled through the successive bodies of liquid.

The bottle carrier comprises a pair of endless flexible traveling supports, preferably sprocket chains 2, located at opposite sides of the machine, and a series of bottle holders'B having their ends secured to the chains. Figs. IV and V iliustrate one of the bottle holders and the means whereby it is fastened to the chains. The bottle holders may be exactly alike, and when arranged as shown by Figs. IV and V each holder comprises a top wall 3, a bottom wall '4, end walls 5 and partitions 6 arranged between the end walls to form a row of bottle compartments. As shown by Fig. IV, the bottle holder is open at one end to receive the bottles, and the opposite end is contracted to limit the motion of the bottles and prevent them from passing entirely through the holder. Each of the chai'ns 2 (Figs. IV and V) is provided with extensions 7 rigidly secured to a bottle holder by means of fastening devices 8 which pass through the wall 4. The bottle holders are thus. rigidly secured to the flexible chains.

9 designates a receiving table, at the right side of Fig. I, located adjacent to the bottle carrier and adapted to receive the bottles, said table being inclined so that the bottles can freely slide into the bottle holders. A discharge table 10 is located at the left side of the machine to receive the bottles which drop by gravity from the bottle holders.

Each bottle holder is open at one side to receive and discharge the bottles, and the same side is provided with an extended closure member l1 adapted to overlap and close the next adjacent bottle holder to retain the bottles therein. In the preferred form of the invention, each bottle holder is rigidly attached to the flexible chains, as previously described, and since each holder is provided with a closure 11 for an adjacent holder, it will be understood that the chains may be bent to open and close the holders. T he means for bending the chains to accomplish this comprises guide wheels 12 located at the left side of the machine and contacting with the chains 2, as shown in Figs. I and III,

and curved guide bars i3 associated with said wheels. 'llhese guide bars are secured to stationary parts of the machine and they have cam races which cooperate with the rotary wheels to bend the chains, as shown in Fig. Hl and at the left side ot Fig. l.

'The chains travel between the guide bars 125 and the wheels l2, and 'owing to the shape and location of these parts, the chains are bent on the wheels l2 to tilt the bott-le holders and displace the closure members l1., thereby opening the bottle holders and permitting the bottles lll to slide onto the table 10, To prevent premature release of the bottles, a stationary stop plate may be located above the table l0, as shown in Figs. l and lll. i

To avoid excessive friction, the sprocket chains 2 are preferably provided with rollcourse throngh the compartments ot tank.

il, the chains 2 pass over the top ot sprocket wheels ll' at the upper portion of the tank, and under tl bottom et guide wheels 18 at the lower p wheels may on of said tank. The sprocket riven by any suitable source ot power. on is directed to the movements ot the i .tle holders and closures at the wheels l? and i8. T/l/"hile the chains pass over the top cri wheels l?, the closures are open-ed, but the bottle holders lie at an angle to the chain links on which they are secured, and said holders occupy substantially upright positions while their links pass over the top faces et the wheels 17, so the bottles can not drop from the holders at thesel points. The bending motions at the lower wheels 18 do not open the closures, and at these points the closures lie at the upper portions ot the holders, so there is no liability of the bottles being dropped from the holders.

Each chain 2 passes under guide wheel 20 near one corner off the tank and over supporting wheels 2l below the tank.

The bottle holders are preferably made of sheet metal and the closure members 11 may be integrally connected to the respective bottle holders. lior example, Figs. lV and V show a bottle holder having a sheet metal wall l which is extended to form the closure member 11. Each wall l is rigidly secured to a portion of the flexible supporting chain and its closure member ll is extended to nenas?? overlap a bottle holder secured to another portion ot the chain. Any desired number oi' bottle holders may be used and the closure members may be secured in any suitable manner. Furthermore, the holders may be constructed in any suitable manner` to receive bottles, or other articles, and the design of the closure members l1 may be varied, as they merely serve as stops to retain the articles in the holders. llach bottle holder is a complete container having Walls whereby the bottle is surrounded, and these enclosing walls are rigidly connected together, the closure being movable independ ently of the rigidly connected Walls so as to open and close the container. ln addition to producing a simple, silent and inexpensive automatic means for opening and closing the holders for the articles to be carried, the Vclosures l1 arranged as herein shown serve as means for closing the spaces between the holders B, so the bottles or other articles resting upon the inclined table 9 cannot accidentally slide into these spaces. Each closure 11 serves as a stop to retain the bottles on said table 9 until the open side of the aldjacent' bottle holder is alined with the bott es.

rllhe closure members l1 are preferably curved transversely to conform approximately to the open sides of the bottle holders and to permit lree movement in passing around the guide wheels.

rllhese members 11, when made of thin sheet metal, are liable to be accidentally bent, and since the bottle holders are tilted toward and away from each other it would be possible for a bent closure member 11 to extend into the space between two adjacent holders B. rlihe wall 3 of each holder is, therefore, provided with an inclined flange 3 at the open side of the holder, said flange being 'formed at the front edge of wall 8 and extended backwardly outside of the bottle coinpartments, so as to provide an inclined deector adapted to force the tree edge of a Cil closure member 11 away from the wall 3 it said free edge should be accidentally displaced to lie between the bottle holders. ln addition to serving as a deflector for a bent closure member 11, each flange 3 serves as a reinforcing element for a sheet metal wall 3.
