scale and in side elevation of the outerend Be it known that I, FRANCIS LEE STUAnT,,, of the apparatus. I

a citizenof the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Apparatus for Conveying, Delivering, and Gathering Material, of which the following is a specification.

This invention relates to apparatus for carrying material brought from a distance by a main conveyer belt to a pile or place for storage or delivery, and also to apparatus for gathering material and depositing it on a conveyer belt which carries it to a distant point. Apparatus of this general kind is shown in my United States Patent No. 1,325,812 of December 23, 1919. In that patent I have shown a trip-per associated with a main conveyer belt which delivers to a boom conveyer which in turn discharges the material from its outerend and piles or stacks it. The boom conveyer carries a grab bucket equipped with suitable operating devices, by means of which the material may be gathered and deposited on the main conveyor belt and conveyed to a distant point or discharged wherever desired.

According to my present invention I provide a combined stacker and gatherer in which the grab bucket instead of being supported by the boom conveyer is hung from the outer end of the boom of a crane, and the boom conveyer is mounted to extend through the crane boom and is supported thereby at a considerable distance from its pivoted inner end. The boom conveyer is equipped with rollers which operate in guides in the crane boom so that while the outer portion of the stacker boom is supported by the crane boom, the former may be raised and lowered'by the crane boom when the latter is moved vertically and a pivotal connection is provided between the stacker boom and the crane boom which permits of the relative movements of the two booms while they are being moved. In this way I provide a combined stacker and crane of simple but efiicient construction and which may be easily operated.

In the accompanying drawings Figure l is a side elevation of a combined stacker and gatherer embodying my improvements.

Fig. 2 is a detail view on an enlarged Fig. 3 is a plan view of the apparatus shown in Fig. 1.

Fig. 4 is a plan view on an enlarged scale oi the lower part of the apparatus, with crane boom and stacker omitted.

Fig. 5 is a view on an enlarged scale and in side elevation ofparts ofthe mechanism.

A main conveyer belt A, which may be 01"- any desired length to convey material from a distant source of supply, is provided with a looped portion or tripper A supported by a frame 13 mounted on a truck C, the wheels 0 of which traverse a track D running parallel with the main conveyer belt. The belt A passes over a deliv ery roller a at thetop of the frame B and thence passes to drive pulleys E and F to which power'is applied by a motor G. Thence the belt passes over a tension pulley H and then forward as indicated. The pulley H is carried by a suitable frame to which is connected a rope J extending over a pulley j and thence over apulley 7c and carries a counterweight K. By this mechanism the desired tension is given to the tripper and main conveyer belt. The mechanism just described'is substantially the same as that shown in my United States Patent No. 1,317,997 of October 7, 1919.,

The tripper delivers through a hopper L to the inner end of a conveyer belt m on the stacker boom M. The belt m is driven by motor mechanism N and the stacker boom is pivoted at a to a frame O carried by a turntable P which is mounted on a truck Q, the wheels q of which trav erse the track D. The truck Q is connected with the wheel supported frame B which by a turntable, the material may be deliv-r ered in any desired vertical plane.

The crane boom R is pivoted at its lower end to the turntable P at and is free to turn about a horizontal axis so that its outer anism t on the truck.

raised and lowered'by a rope U connected bucket of well known construction, which is operated by a rope T connected with a Windlass t operated by suitable motor mech- The crane boom 1s at u with the outer end of the crane boom andextended to a motor operated Windlass V on the turntable P. The motors V are geared as shown at o to a shaft 0, which is geared at o to mechanism for rotating the turntable The crane boom isot skeleton construction and has a longitudinal opening in it through which the stacker boom extends. The outer portion of the stacker boom is equipped with rollers m which travverse guides 09 on the crane boom, the ar rangement being such that as the crane boom is raised and lowered the stacker boom is also correspondingly moved and is at all times supported and braced near its outer end or at a considerable distance from its pivotal connection with the truck.

; By the mechanism shown the crane boom may be set at any desired angle relatively to "the ground level and will correspondingly raise and lower the stacker boom which may thus be set to deliver from any desired horizontal level or at any desired distance from the ground. Inasmuch as the crane boom =18 supported by the turntable and as the stacker boom is connected with the crane boom to move with it sidewise or about a vertical axis, the crane boom may be set to deliver material at any desired vertical plane; It will be observed that when the turntable is moved about its axis it not only moves the stacker boom sidewise by reason ofthe connection between the inner end of the stacker boom and the frame of the turntable, but a sidewise movement is imparted to the outer portion of the stacker boom by reason'of its connection withthe crane boom.

An. important feature of the invention consists in pivotally connecting the inner end of a stacker boom to a turntable and in supporting the outer portion of the stacker boom by another boomwhich is connected to the turntable below the pivotal connection of the stacker boom with the turntable. Such construction'is simple and eflicient and provides novel means for supporting and bracing the outer portion of the stacker boom, which in somecases is of great length. This feature of my invention is believed to be novel whether or not said supporting boom "is used to support gathering mechanism.

which may discharge onto the main conveyer belt as described in my Patent No. 1,325,812 of December 23, 1919, above mentioned.

I claim as my invention p 1. An apparatus for delivering material, comprising a truck, a turntable thereon, a vertical frame on the turntable, a stacker boom equipped with a conveyor and pivotally connected at its inner end with the frame on the turntable to move about the horizontal axis, a main conveyer belt delivering to the stacker boom, and a boom connected with the outer portion of the stacker boom at a considerable distance from its pivotal connection with the turntable and which is pivotally connected with the turntable below the inner end o1 the stacker boom.

2. A combined stacker and gatherer, com prising a'truck, a turntable thereon, a crane boom pivotally connected withthe turntable to move about a horizontal axis, gathering mechanism carried by the crane boom,

means on the turntable foroperating said gathering mechanism, means on the turntable for raising and lowering the crane boom, a main conveyer belt equipped with a tripper, a stacker boom provided with a belt to which the tripper delivers, a pivotal connection between the stacker boom and the turntable permitting the stacker boom to move about a horizontal axis, and sliding connections between the outer portion of the stacker boom and the crane boom whereby the outer portion or" the stacker boom is supported by the crane boom and the stacker boom is raised and lowered by said crane boom.

3. A combined stacker and hoisting crane, comprising a truck, a turntable thereon, a crane boom p'ivotally connected with the turntable to move about a horizontal axis, gathering mechanism carried by the crane boom, means for operating said gathering mechanism and for raising and lowering the crane boom, and astacker boom pivotally connected with the turntable'atits inner end and slidably connected at its outer portion with the crane boom.
