SIDE-WALL TRAVELER.

Application fuea October 14, 1920. serial No. 416,863. V

To (1U 107mm t may con oem l Be it known that I, LooMIs L. KELLY, a citizen of the United States, residing at Norfolk, in the county of Norfolk. and State of Virofinia, have invented certain new l,and useful Improvements in Side-Vall Travelers, of which the following is a specification. i This invention relates to side wall travelers and has among its objects to provide an improved mechanism whereby material such as coal or ore may be conveyed fromanyone of a series of pockets or bins to a receptacle positioned alongside of the structure containing the pockets or bins. The invention consists of the formation, combination and arrangement of yparts as will be herein described and particularly claimed The invention is intended primarily* for use in connection with piers for the loading of material such vas coal or ore into vessels berthed alongside of the pierV or dock. Such piers are usually arranged with elevators for hoisting dropbottom cars to a deck of the pier at considerable height above the -vessel. The material is dumpedffromV the cars into pockets or bins formed in the pier whence it may fall by gravity orbe other- The deck of the pier and the pockets are necessarily at a fixed elevation. The vesselsto be loaded are of varying heights. The change in tide also requires means for yconveying such materials to be adjustable vertically. Itis furthermore desirable that lthe conveying apparatus be adjustable along the pierand laterally with respect to the pier, in Order that the varying `positions of loading hatchways may be accommodated. Thepresent apparatus is arranged to provide all such flexibility and at the same time to khandle the material in a satisfactory and economical manner.

In the drawings, which show a preferred embodiment of the invention, Figure'l is an end elevational vview of the side wall traveler of my invention, the cross sectional construction of the dock and pier being shown indotted Outline. In this lligure the extreme positions of the laterally extending material chute are also shown in dotted lines. 'Figure 2 is a side Aelevational view of the traveler, various portions of the pier being 'shown in' dotted outline in this dgure also. Figure 3 is a horizontal section taken through the traveler on the line AA o Figure 2. Figure 4 is a vertical sectional view through the vertical' leg of the apparatus, this view being takenon the' line C'C' of Figure 6. Figure 5 is' a transverse sectional view taken on the line BB of Figure 1. Figure 6 is a front elevational view of thev vertical leg ot the device detached from" the the numeral 17 denotes the face'of the dock against which vessels to be loaded' 'are berthed. The frame vwork of the pier is shown in dotted .outline and is denoted by the numeral 18, the pier having one or more tracks 25 onits top deck for thel accommodation of material cars. ,The .numeral A16v denotes one of a series of pockets located beneath the material track 25 and into which the coal or other substance is dumped from the car. The pockets 16 are arrangedlon-l gitudinally along the' pierV and have' inclined bottoms so that the material will a'll by gravity throughsuitable discharge 'gates such as 22 at the lower and kouter 'extremity of each pocket. 'Such construction'ofpier and pockets is in common use where material in bulk is loaded into vessels. 'y

The present invention has to do 'with means for receiving the material'trom .one 4of the pockets 16, through the `,discharge gates 22, and deliveringY it. in a convenient yand satisfactory manner into the hatch of a vessel positioned alongside of the dock 17.

In my previousl application, Serial #1103,280,

iled August 13, 1920, I have shownand de'- scribed a' mechanism co-operating withra similar arrangement'o'f 'pier for delivering material into the holdk of" a vessel through a power operated mechanical trimming machine. The present device is intended 'primarily for the delivery otcoal, by gravity', into open hatches, `and without the use of a trimming machine. The use of travelers' of the present type is contemplated along piers equipped with machines of the former type, the former machines'to be used principally for delivering cargo coal. Bunker coal is ordinarily'v delivered through open hatchways and bunker trimmingmust ybe doneV by hand", Vwhereas cargo trimming is-nowfdone by machinery with a great saving of labor. It is therefore expectedV that` therunways shown as applied to thel pier in my previous application may be utilized for the accombox.

cad

modation of the present side wall traveler. It being understood that a plurality of pockets 16 is provided on such piers, the present arrangement of traveler is arranged adapted to serve any one of such pockets. To this end a vertical plane girder 21 is supplied for the active length of the pier. Upon the top of this girder is a runway rail 26 which accommodates the traveler wheels 8. These latter carry all of the vertical load of the traveler. A continuous girder 20, lying in a horizontal plane, is also supplied near the top of the pier, the same having a runway rail 27 on its inner face for the accommodation ot the horizontal thrust wheels 9 which are carried by the traveler frame. Near the base of the pier is a continuous horizontal girder 19 which accommodates horizontal thrust wheels 10, these latter being provided to resist the horizontal thrust at the bottom of the traveler frame.

The traveler embodies a main trussed structure or trame 1, which has suitable brackets or extensions 28 and 29 for the accommodation of the aforesaid wheels 3. 9 and 10. The frame is arranged along the side of the'pier in a substantially vertical fashion and may be propelled by any suitable means along the runway rails into position in front of any one of the pockets 16. The detail construction 'ot this frame is immaterial so long as it properly accommodates the various operating features ot the device, but it is preferably arranged with lattice sides and an open center portion, the coal chutes and handling machinery for the same being arranged in this central portion. By this arrangement the traveler may be made of light weight and at the same time is best adapted to accommodate the machinery and to resist the various forces and moments set up in the structure.

The coal handling mechanism consists primarily of a vertical leg 2 which is secured to and carried by the trame 1. This leg is so located laterally of the pier that when the traveler is moved along the pier the open top of the leg 2 will register with one or another of the aligned discharge openings controlled by the gates 22. The leg 2 is arranged to slidably accommodate within its walls a vertically-movable sliding-box 4. This vertical leg has a normally open front face and-by a system .ot plates 31 carried upon the top of the sliding-box 4, and arranged to travel in' suitable ways 32 in front of the leg 2, the active portiony of the 'leg 2, or in other words -the portion of the leg above the `slidingboX,-will always be closed at the frontdby means of the said plates, irrespective ofthe position of lthe 'sliding- The 'sliding-boxfl' may be moved lto any .position vertically .of the leg 2, the

.drum 7 and thecabl 112 being supplied 'tor this purpose. This cable 12 passes over suitable guide sheaves 13 and 14 andaround equalizer sheaves 15, attached to an equalizer lever 33, which is in turn attached to the sliding-box 4 by means of links 34.

The sliding box may thus be raised or 'lowered by means of the drum 7 and the cable 12, which are carried by and with the frame 1. As the sliding box is raised, the various plate sections forming the front ot the leg 2 are picked up in serial fashion. When the sliding box is lowered, the sections o the front are also lowered, one at a time coming to rest upon properly positioned lugs 35 arranged within the guides 32 for this purpose.

The discharge opening in the lower end of the sliding box 4 is controlled by means of a coal gate 5, a drum 24 and cable 23, carried the frame, being provided to manipulate this gate. An outwardly extending discharge chute is suspended at its inner end from the plate 39 which forms part of the sliding box 4. This is accomplished by means of the cables 37 which are aiiixed at their upper end to brackets 36 carried by the sliding box plate 39. The lower ends ot cables 37 are wound around cams 38 which are attached to the inner end of chute 3, this arrangement allowing the inner end of chute 3 to adjust'itself to different positions. The cables thus allow the outer end of the chute to be swung in a horizontal plane, a suitable abutment rocker 30 being arranged for the bearing of the chute against the sliding boX.

The outer end of the chute 3 is operated and adjusted by means of a cable 11 which is wound upon a drum 6 carried by the frame 1. The outer end of the chute 3 may thus be drawn up into a position substantially parallel with the trame 1 or may be lowered into an outstanding or sloping position so that the coal or other material will travel 'down this chute by gravity and be discharged into the hatchway. The inner end of the chute 3, being carried upon the sliding box 4, is adjustable vertically with the same.

In practice the traveler is propelled along the runways until the vertical leg 2 is positioned directly under the desired pocket 16. The sliding box 4 is then lowered, carrying with it the inner end of the chute 3, and the outer end ot the chute 3 is also lowered, by means of the cable 1-1, until thejouter end of the chute 3 is in thel vertical Aposition desired for the particular height lof vessel to be loaded.' The outer end of the chute 3 is then swung in a radial fashion to bring it immediately over theV hatchway of the vessel, and by means of the gates -22 and 5 the flow of material tothe vessel may beV controlled. y When it is desired to move the traveler from one pocket to another,

chute 3 is drawn up as heretofore described, when it will clear the superstructure of the vessel and can therefore be movedl alongside of the same.

I have thus described an embodiment of my present invention. Various changes and modifications are contemplated, Within the scope of the appended claims, Without departing from the spirit thereof.

Vhat is claimed is:

l. In a side Wall traveler, a pier having longitudinally arranged material pockets, a frame movable along the pockets, the same carrying a fixed gravity leg arranged to register with the discharge openings of the pockets and to receive material therefrom, an outwardly extending chute arranged to receive material from the gravity leg and to discharge it at a point removed laterally from the pier, and means carried upon the said movable frame for the vertical and lateral adjustment of the last named chute.
