LOADING MACHINERY.

To all whom it may concern:

Be it known thatl, GEORGE H. HULETT, ot Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Loading Machinery; and I do hereby declare the following to be a full, clear, and exact description of Athe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to improvements in loading machines, the object of the invention being to construct a. traveling frame orl invention consists in. certain novel features of construct-ion and combinations of parts as hereinafter set Jforth and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation illustrating a machine embodying my improvements. Fig. 2 is a plan view of the same, and Fig. 3 isa front elevation.

1 represents a frame or tower provided at its bot-tom with wheels 2 to run upon tracks 3 located near the edge of a'dock 4. Tracks 5 are also located on the dock in such position that cars 6 may be run under the tower or so that the tower may be moved so as to become disposed over said cars.

Located within thev tower 1,- are vertically disposed guides 7 for the accommodation of vertically movable bars 8' which are provided at their lower ends with hooks 9 toV engagel ribs or flanges 10 on the car 6. The bars S are carried by the :trames of sheaves 11. Cables 12 (secured at 13-to the upper portion of the tower) pass over the sheaves 11 and over sheaves 1Iv at the top of the towcr,-said cables then passing down wardly and wound upon a drum 15 located within a machinery house16, in which latter Specication of Letters Patent.

suitable driving mechanism is also located. It is apparent that.v when the hooksgare in engagement with the flanges of a'car and the drum 15 is rotated in onedirection, the

vcar will be elevated and when it shall' have reached a. predetermined height, *the mate' rial therein will be discharged therefrom (the car being constructedof `the sidedump type). onto a pan or apron 17 and from' the latter to a chute 18'. In order to assistJin the` raising of a car, a weight 18a is'prvided. Y

This weight is mounted to move on `an '1n'- clined .way 19 afforded bythe back of the tower and is connected by meansv of suitable cables 2O with the drum 15, on which latter it is wound in a direction opposite to thel winding of the lifting cables 12. 'The weight 18 may be made to approximately counterbalance the weight of an empty car so that the latter may be readily lowered'by causing the drum 15 to rotate in aI direction opposite' to that necessary |`for raising the car.

The pan or apron 17 is hinged or pivotally connected with a transverse member 21, as indicated at 22. This transverse member 21 is provided with xed threaded sleeves 23 through which vertically disposed threaded 1'ods'24 pass,-the lower ends of said rods being suitably swiveled in thek lower portion of the tower framework and to their upper ends, beveled gears 25 are secured. A shaft 26 mounted upon the tower, is provided at its respective ends vwith beveled gears 27 for transmitting motionv to the gears 25 on the threaded shaft. A motor 28 is also 1ocated upon the tower and transmits motion through the medium of 'suitable gearing to the shaft V26. ,By these means motion is imparted to the threaded rods'QI for raising or lowering the transverse member 21 and 'disposing the inner endet' the pan or apron 17 at any desired height on the tower so that the mechanism can be adapted to operate ior discharging material into boats of different heights. A rameor bracket 29 is secured to the outer portion of the pan or apron 17 and carries ao.4 operators cage 30, from which an operator can control mecha.-` nism at 31 for manipulatii'ig the chute 18.

vThis chute has' a universal connection at its l `ing connected means of cables with theupper end with` theJA discharge end of the pan .orapron'17and iti is alsol made in telescopingvv sections,'the lower of said sections'be- ,rangement of these cables do not constitute a part o f ,my present invention and hence aA more: minute description thereof islunnecessary herein.

j 'Theframe or bracket V29A supports sheaves 33 and over these sheaves,'cables 34., pass,

said cables also passing over shea-ves 35 and 3.6 atlthe. top of the tower. One end of each of said cables is secured at 37 to the upper portion of the tower andthe other end of 'each of said cables extends downwardly from sheave 36 and is wound upon a drum j 38 inthe machinery house 16'.' By operating this 'drum the outer portion of the pan or vapron 17 and .the chute 18 connected therewith can be raised or lowered, thezpan or apronl then turning on its'hinged orpivotal 'connection with the vertically movable .transverse member 21.

For causing theftower'to travel along the dockfso that it, can' be easily and quickly positioned with respect to the boat or a particular 'j hatch thereof, lthe mechanism now` tobe described will be employed: Mounted upoiithe top ofthe tower are drums 39 provided witlfi'gea'rs 40 which receive motion fromvpinions 41 on 'a shaft 42. This shaft is provided with a gear 43 receiving motion from lar pinion@ on a shaft 45,-the latter beingl,geared to the motor 28 and suitable clutchesfarjelocated on this shaft for causing theper'ation of the motoi` to drive either the .drums l39 or the shaft 26 of the p an or apronraising mechanism. .Cables 46 are .woundy uponithe drums 39, extend downwardly therefrom, having their intermediate portions passing over sheaves 47 at the bottom of the tower and the free ends of these cables extend from the tower in opposite directions and are secured to the dock at points some distance removed from the tower.v In other words the cables 46 are secured at their respective ends at respective ends of the trapkway on the dock uponwhich the :tower travels.

From the construction and arrangement of apparatus above described, it will be apparent that the tower can be quicklymoved and accurately positioned for discharging material into a boat located alongside the ,the `latter can be adjSted at any suitable.

taciones height-to accommodate .it to Vthe particular height ofthe boat into which the material'is to be discharged, and that the outer end of the apron can be raised or lowered and also that the chute can be lengthened or shortened oi "oved outwardly or inwardly to insure the discharge of the material evenly in the hnld of the boat.'

Numerous slight changes might'be made in the details of construction of my invention without departing from the spirit `thereof o r limiting its scope and hence I do n ot wish to restrict myself to the precise details-herein set forth. l

Having fully described my invention what. I claim as new and desire to secure by Letters-Patent, is,-

2. The combination with a traveling tower, a chute, and a vertically adjustable pivotal support for said chute, vertically movable hooked bars to engage a dump car, means for raising said hooked-bars to elevate thedump car to position to dischargeinto said chute,` and means for yraising and lowering the vertically adjustable chute suport.- i

3. The combination with a tower and vertical guides therein, of hooked bars movable in said guides and adapted to engage a car for elevatingthe same, sheaves connected with said hooked bars, sheaves mounted on the tower, cables passing over said sheaves and secured at one end to the tower, drums over which said sheaves pass, and means for operating said drums.
