INVENTEI R. 5A r1 HUBEY wnN ESE: Es:

v To all whmh'i't 06mm.- Be it knownthat I, SAM H. LIBBY, a citizen of the United States, residin at East Orange,-county of Esex, State of e w J ersey, have invented certain new and useful Improvements in Conveyor Systems, of

intended though it In conveyer systems of the general type above mentioned so-called gauntree cranes exten are often employed. These cranes consist in general of abridge built of structural steel arranged for travel upon. two tracks which fore, transversely to the track carried by the latter upon \vhicha carrier is arranged to travel. This bridge generally moves over the area in which material is to be distributed and the carrier never leaves the bridge track.

It is'a'n object of my invention to provide means whereby the carrier can not only be operated upon the bridge, but can also be the brid e track and the fixed track can bev made wit out requiring the operator tdbring,

runoff the bridge on to a fixed trackdeading to an' area not covered' by the movement of the bridge.

One particular feature of my invention is the means whereby the connection between the bridge accurately to a definite point, thereby preventing loss-of time in operation which would naturall result if exact aline ment between the bri ge track and the fixed track were necessary. I To the above end, I provide in a conveyer system having a travellng bridge carrying a trackupon which a carrier 0 rates-and having a fixed'track upon whic it'is'desired to at times run the carrier, a yielding3 tl0kof track serving as a connection between the bridge track and the fixed track. 1

My-invention will be fully understood 1 from the following description taken-in con nection with the accompanying drawing in Specification of Letters Patent. Application and October 21, 1909. Serial No. 523,779.

GQNVEYEB. sYs'rEin which one embodiment 'ofsaid invention is illustrated in plan view in a more or less diagrammatic manner.

Referring to the drawing, let us assume that A is a railroad track or other material, is receive at a manufacturing plant. Let us also assume that B is an area used for the storage of the coal or as needed and'is used in the boiler house or other building C. A gauntree crane, or travlan view at D, travels upon tracks E and said bridge being arranged as shown to 'move over the storage area B and that portion of the railroad track A. adjacent to said area. Upon the bridge D is atrack I upon which a carrier G travels, said carrier being provided with a grab bucket, or other hoist, of any suitable form. In the arrangement shown it is assumed that the o erator is carried in a cage on the carrier and is able 'from this osition to control the movement of the bridge D upon the tracks andE, the travel of the carrier G upon its track, the hoisting and lowering of the bucket, and, in fact, the whole operation of the conveyer any suitable and well-known way which, since it forms no part-of my invention, has not been illustrated in the drawing and need not be described. 7 g

, Supported within'the building 0 is a fixed ,track H, the end of which extends out of said building and over one end of the area B, as shown. In the particular/arrangement shown, the end of the track'H is curved and is provided with a iyoted section Ifpivotcd at z'and'biasd to t eposition shown in full lines by a spring connected between-a fixed bracket fendthe pivoted section I as shown. 'Thepi-vqtd-action I at-its outer i" in any. suitablemanner. .In the particular system shown, the I bridgFD is provided with a switch member "K, p1voted at k, which can be thrown by the operator either to theposition shown in full lines, in which'it -'is in:alinement with the straighttrack'F, or to the osition shown *in dotted lines, in which sai switch memeling. bridge, diagrammatically indicated intrack F carried by the Elisa enliven, NEW JERSEY, assra'non.

Such swiiltlch devices and the means for operating-F t em;

The outer end of the section of .5 track L is so arranged that,when the bridge D is near that end of its travel toward the buildin C, said end enga c with the free end i of -the pivoted trac member I and will allow the carrier to'be run from the 1'0 section L on to the section I. and thence to,

the track H. It will be obvious that. with the arrangement shown it will not-be nee I I essary for the operator to move the bridge D to an exact position but only to an approxi mate y certain osition saywithin two or three-feet, in or er .to eiiect a connection beA I tween the track.F carried b the brid e D and the fixed trackH. e ends 0 the switch member K, the section of track L,

and the pivoted section I should, of course,

be provided. withthe ilsuali devices which prevent the carrier from bein "of! the ends of these parts of the trac 'unless'they f are in correct alinement with-the cooperat- 26 ing parts. Since these devices form -nolfiarti asp:

, It will, ofcourse, be understood that the system can be modified iq many ways,- for example,.by omitting the switch memberK and a portion of the track L and'arranging 40' one end of the track F to engage'directly] with the pivoted member I. It will be clear also that any number'of fixed tracks may be provided to whichtheoperatorcan runfthe carrier.
