` March TITTTIED STATE@ PATENT WILLIAM rHoi/IAsJAMEs, or CHICAGO, ILLINOIS.

Original application led March 30, 1908,"Seria1 No. 424,242. Divided 8, 1910.` Serial No. 576,183.

To allwwm it may concern:

Be it known that I, WILLIAM THOMAS JAMES, a citizen of the United States, residing at Chicago, in the county of -Cook and State of Illinois, have invented certain new and useful Improvements in Conveyers, of which the following is a speciiication. j

rIhis invention has reference to the provision of an improved form of apparatus for handling coal or other like material in bulk, certain structures in which itis convenicntly employed being shown in my copending application, Serial No. 424,242, filed 30, 1908, of which this is a division. The invention has for itsprimary objects, the provision of an improved form of conveyer chain having buckets mounted therein, an improved form of .stop device for alfording a support for the bucket while` it is in loaded position, and also acting as a `stop for the movement. of the bucket when it is tripped in dumping the material, and to provide an improved form of'construction for tripping the bucket Vwhen traveling in a nonhorizontal or vertical plane, which said trip device is constructed so that it can be thrown into and out of position at will-depending upon the place at which the bucket is intended to dump its contents. `30

A further object of the invention is the provision of a carrier chain of this general type, composed of link sections each having one bifurcated end and one single or plain end, and means forengaging saidV ends of the adjacent sections together, such link sectionsbeing provided with bucketesupporting v means intermediate the ends.`

The above, as well as such other objects as may hereinafter appear, Iattain by means of a construction which I have illustrated in preferred form in the accompanying drawings, wherein l Figure 1 shows in side elevation the upper end of a` conveyer embodying my improvement; i

Fig. 2 `is another partial view.in elevation-of the apparatus shown in Fig. 1;

,Figf 3 is a View of several of the buckets carried by the chain, shown as moving in vertical direction, with one of thebuckets justdumped to discharge its contents;

1 Fig. 4 isanotherview of the apparatus shovnin Fig. 3,; showing it in a dierent elm/atterra j coni/*Erna Speccation of Letters Patent.

1 to 4 inclusive, it will upper ends of rockerarms and this application led August Fig. 5 is a view showing a slightly modified form of the dumping device, and

Fig 6 is a view in elevation of the mechanlsm shown in Fig. 5.

Referring now more particularly to Figs. be seen that I have thereinA indicated a conveyer chain 7 arranged to be carried at its upper end by a suitable sprocket 8 mounted on a shaft 9 on the other end whereof is a similar sprocket carrying a. similar chain or portion of conveyer belt, between which portions of the conveyer belt I mount a plurality of buckets 10 `as shown, the same being adapted to travel in a path where the material is lifted vertically as indicated by the arrow in Fig. 3, and arranged to be dumped while the buckets are traveling in a vertical direction upward, as shown in saidFig. 3, into some suitable trough or other receptacle 11, by means of the tripping arrangement to be hereinafter more particularly described.

The side parts of the conveyer chain are composed of links indicated in Figs. 2, 4, and 6 particularly, such link members 13 having bifurcated upper ends at 14 and plain lower ends as indicated at 15, the plain ends being engaged within the bifurcated ends as shown, and the whole held together by suitable fastening bolts or other devices 16. Intermediate the ends of the link members 13 is a hub 17 through which extends the trunnion or support 18 which serves for carrying the bucket 10, there being a trunnion support at each end as shown, and each end of the bucket being provided with an angle-iron projection or bracket 19 preferably secured by rivets 20, with the iange 21 thereof extending laterally in position such as will engage with the trip roller 22 when the latter is in position for dumping the bucket, bringing the same into the position indicated in full lines in Fig. 3, in which the contents will be discharged into the trough 11 or any other suitable receptacle.

The trip roller -22 has a counterpart on the other side of the bucket, so that the brackets 19 will have simultaneous engagement on both sides of the bucket to take the strain better, and the rollers are carried upon the 23 mounted on rockereshafts 24, so that if desired, as indicated yin Figs. tend 5, therollers 2.2 can be aimultaneeuely swung te the right cut.

the buckets to pass without dumping, whereby if another tripA device or pair of'levers 23 carrying similar rollei's 22 is mounted in another part of the path oi' movement ot the buckets, the contents oi the bucket can be dumped in such other position, as for example where it is required to distribute the contents oi the' buckets lirst in one horizontal plane and later in another higher horizontal plane as the bins or receptacles below become iilled.

As a ineans for 'connecting together' tlie two conveyer chains I provide a strap or connecting device Q5, indicated more plainly perhaps inFig. t, and said strap Q5 is secured to the side links as indicated at 26, whereby it holds the said side links in proper relative position, and also serves as a stop for the buckets 10, being so placed as to stop the buckets both in the loaded and inthe unloaded position, as plainly indicated in the several Iigures.`

This strap or connectingdevice 25 also serves to permit the bucket vto right itself into operative position after, having discharged itsr contents, the bucket being stopped in such vertical position by contact with the rear edge/ot the stop which, upon reference to Fig. 3, will be seen to be slightly inclined from the perpendicular.

Having thus described my invention and illustra-ted its use, what I claim as new and desire to secure by Letters Patent, is the following:

l. In a material handling apparatus in combination, a pair of opposing carriers each composed of a pair of chains, each comprising a plurality of link sections, means connecting the ends oil adjacent sections togetlier, a conveyer bucket pivotally mounted between the cari'iers, and means between the carriers adjacent said bucket for stopping the bucket in bothits loaded and unloaded positions.

2. In a' material handling apparatus, a

pair of opposing carriers, a normally swing-V ing conveyer bucket pivoted between said carriers, and means connecting said carriers together for stopping the bucket in botlr'its loaded and unloaded position, said-last mentioned means being so constructed as to per-l mit the bucket to right itself into operative position after discharging its contents.- 3In a material handling apparatus, a pair of opposing carriers, a conveye'r bucket pivotally mounted between said carriers, and a bar between the carriers located adjacent the bucket, for stopping the bucket in both its loaded and unloaded positions.
