To all 'ev/10ml vimay co'cewb:

le it known that I, LFRED J. A'VIvIAr citizen ot the United States, residing 1n the f vity and vounty of Denver' and State of thejconveyer, doubles the' coni'fe'yer-run Colorado, have invented certain new andnselul improvements in'l}o`. \*#Car Loaders; and l do declare the following to be a full, elear,`ai1dl exact deseriptionof the'invention, such'ns will enable others skilled in the art to which it appel'tai-us'to make and'use thel saine', referencebeing had to the accompanying;- drawings', and'to the charactrsf'of ref-' ereh'ce marked thereon, oit this specticati'on.

My invention 'relates -to im box Car-loaders; my object'bei'ng to rov'ide an appi'u'atus of this characterA wbielh shall he comparatively simple in e'onstru'etion, economical in cost, reliable, durable and eficient in use. y l

TIyim'proved apparatus includes alongi t r 1d i h ally movable Conveyer-frainelinembei' which telescopes inthe main frame of .which ferie@ Pel-ft the'loader,the resulting slaek'in the*1 conyer being taken up by a second member slidable en the main frame and moved simultaneously in *the reverse direction,r the said slidableV member for'4 taking 4upjthe slack'being interposed between the upper and lower sprockets carried shaftsjour? nalcd in the' main frame. ene e,l as the telescoping conveyer-fraine-member moves rearwardly, the slidable which isdn- ;aged by the c'onveyer,L moves forwardly, and beingl located 'between the'upper and lower shafts carrying` sprockets engaged by between the slidable Ymember and" the two sprocket-carryingA shafts, thus taking.;u ptlll slack in the conveyor simultaneously with the rearward'travelo the latter; Byvir! tuel of thisconstruction, the conveyer may he extended and shortened'within'a considerabl(` range of adjustment, thus making it practicable t'o extend the free endof the eonveyer to either end o'f'thel car, or asI near y thereto as is desirabley for loading purposes,

and the'n gradually'move the free end o'f the cony'eyer toward thev center; of tliecar' as thel latter` is filled.' 'Provisionzisalso' 'nadefiV l'wdilymovin'g the'main' frar'rielworkoi .an

'n l' he' Same referme cheraetersindeate the Samrtentlthe. tiers w I Jftthe n imerall desi nate a track upon which' is mounted a truc 6 having wheels 7' mountedon axles, the latter carrying which the main frame is longitudinally and. tiltably adjustable.

vj'ustment is effected by means of two blocks The longitudinal ad- 17 freely slidable in the frame-members 15, the said blocksforming bearings for trunnions 18 secured to the main frame bymeans ofwsuitable fastening devices 19 passed through flanges 20 formed at the base or inner extremities of the trunnions. Each -block17 is freely slidable in its corresponding auxiliary frame-member 15 and, is acf tuated to carry the main frame in either di rection by means of a screw 21 j ournaled in the opposite ends 22 of each auxiliary frame-member. At the forward extremity cf one of these screws is applied a handwheel 23 for .manually rotating the screw.A The rear extremities of the two .screws are equipped with sprocket-wheels '24 connected by La chain 25 whereby, as one screw is turned, bo-th screws .will be rotated and impart uniform travel to the blocks 17 where' bythe main frame is moved bodily either forwardly or rearwardly with referenceto the turn-table.

The manner of tilting the main 'frame upon the blocks 17 or with reference to the auxiliary frame will now be described. Secured to one of the blocks 17 by means of suitable fastening devices 26 is a verticallydisposed plate-arm 27 whose upper extremity is transversely reinforced as shown at 28, this transverse portion being concaved and toothed asshown at 29 toL receive a worm 30 formed on a shaft 31 journaled in bearings 32 for-med on fone side of the main flange. The toothed upper vextremity of the plate-arm 27 lies in an arc struck from the center of the trunnions 18. The forward extremity of the worm shaft 31 extends beyond the main frame-work and is fashioned as shown at 33 to receive a crank or hand- As illustrated in the drawing, the auxiliary frame 16 is composed of Vvertically-arranged suitably-supported parallel steel tive sprocket-wheels constitute upper. and

lower supports at the rear extremity of the apparatus for the endlessl conveyer; while the forward extrem-ity of the conveyer is Supported on sprocket-wheels 46 fast on a -shaft 47 journaled inbearings 48 carried by depending brackets 49 mounted on the forward extremities of two hollow bars 50 which telescope freely in hollow coperating `members 51 secured to the inner surfaces of the oppositevside-plates 35 of the main frame. telescoping' member 50 contains a solid block 52 having a threaded opening 4in which is threaded a longitudinally disposed screw 53 which is journaled in the rear extremity of the main frame' as shown at 54. Similar screws 55 are journaled 1n the; lower part of `the main frame and are threaded in blocks .56 slidably mounted on 'tracks 57 secured to the inner surfaces of' the opposite side-plates of the mainframe. Journaled in these blocks is a transverse shaft- 58 carrying sprocket-wheels 59 which are engaged yond the same and are equipped with` sprocket-

wheels

60 and 61, the fo-ur sprocket wheels being engaged by a chain 62 to cause the four screws to operate in harmony. Each screw extends rearwardly beyond its sprocket-wheel as shown at 63 and is formed polygonal, preferably square, in cross-sec- The rear extremity of each/ tion whereby 1t is adapted to receive a handwheel-or crank for simultaneously operating vthe four screws of the apparatus.v

ybers 50 lto travel rearwardly, the bearingblocks s carrying the shaft 58 with the sprocket-wheels 59 will be carried forwardlyv to take up the slack in the'conveyer caused by the rearward movement of the telescoping'members 50.

Suspended fromthe lower platform 37 of the mainframe is a motor Gl (preferably electric) which is secured to said platform by suitable fastening devices 65. The armature shaft ilt of this motor is equipped with a sprocket-wheel 67 engaged by a chain 68 leading to a larger sprocket-wheel 69 fast on a shaft 70 journaled in the lower part-of the main frame. Upon this shaft is also mountedr a smaller sprocket-wheel 71 connected by means of a chain 72 with a larger sprocket-wheel 73 fast on a shaft/74 intermediate the shaft GG and the shaft 70. Upon the outer extremity ofthe shaft 74 is a smaller sprocket wheel 75 which is connected by means of a chain 76 with a sprocket wheel 77 fast on one extremity of the shaft`-l1,

the conveyer.

whereby power is applied to the endless convcyer for imparting the necessary movement thereto for carrying the'coal during the loading operation.

The telescopi'ng member 51` connected with each side-plate 35 of the frame, is provided with a flange 78 supported by a cleat 79 inV `a position Slightly above the upper platform 86 of the frame whereby a space 80 is left below the 'flange 78 and communicating with the opening 81 which is adapted to receive the telescoping member connected with the conveyer asheretofore explained. This telescoping member 50 has a. flange 82 adapted to enter the space 80 and slide freely therein :during the endw-ise.- adjustment of The telescoping member 51 extends the entire length of the! upper portion of the lmain frame 16 and the flanges T8 of the two telescoping-members 51 form a support for the chains 44 of the conveyer, the hinge-pins 483 of the links 84 carrying'rollers 85 which travel upon the flanges 78 until the cud of the main frame is reached, when the said rollers engage the flanges 82 of the telescoping members 50, which anges support'the conveyer until the forward extremity of the members 50 is reached lwhen the conveyer passes downwardly around the sprocketsl 7 6 i of the shaft 47.

From the foregoing description, the use 4and operation of my iiii[ r0\'ed car-loader will be readily understood.

I In order to use the loader it is lirst inouted on a support-8G located outsidethe car and provided with 'tracks 87 which the wheels S of the truckengage, the said rails of thc `track being extended into the box carl RS. The loader whichis in the condition indicated by dotted lines, outside the car,'in Fig. 10-that is tosay, with its conveyer adjusted to reduce themacliine to its mini` in um lengthfis then run in to the car and turned upon the turn-table during its entering movement, after which the conveyer is extend.

ed until its forward end occupies a posit-ion -close to one end of the car. This is accomplished by turning the screws 53and 55 in a' direction 'tocause the structure composed of the telescoping members 50 to travel forwardly, while the structure including the slidable blocks 56 travel rearwardly. ln ordei to eect this result,.it is only necessary to apply -a crank or hand-wheel toone of the projections 63 of one of the screws 53 or Theturni'ng of one of these screws in the proper direction will turn all thel screws in a direction to accomplisl'rtlic aforesaid result by virtue of the connection of vthe four sprocket-wheels G0 andl, by means of the chain 62. rlfhe forward extremity of the conve-yer is then lowered to :i position close to the bottom of the car. This is accomplished by turning the shaft 31 whereby t-he worm 30 is caused to travel on the curved toot-hed upper extremity of the plate-arm 27, in the proper direction. During this operation, the trunnions 18 of the main frame turn inthe blocks 17 of the auxiliary frame by virtue'of the construction heretofore described. As'soon as this is accomplished, the motor 64 may be set in motionwhereby 4motion is' communicated to the endless cn- 'veye.r. The coal or other maten-iai to be the rear end of the conveyer fromia chute 89.

' The coal may be continuously fed `through thechute to the co'nveyer, which. being in constant motioncarries itto the end ofthe car and delivers it to the floor thereof. In this manner the coal is carefully deposited in the car without any opportunity for breakage orthe production of slack. As the end of the car fills, the forward extremity of the conveyer is gradually raised and when the coal has been deposited in the car end to the desired depth, the forward extremity of the conveyer is retracted or withdrawn. In this manner the car -is gradually kfilled from the end toward thecenter until the forward extremityl of the conveyerhas, by virtue of the adjustment heretofore explained, reached its rearward limit of movement.

'lhe main frame may theny be retracted bodily or moved jrearwardly upon the auxiliary frame .16 mounted on the tur1i-table,'this operatxon being accomplished by turning one of the screws 21 whereby motion is imparted to both screws through the instrumentality of the connecting chain'25. As these screws 21 are turned in the proper direction, the main frame-work, together with vthe mechanism mounted thereon, is caused to travel rearwardly' on theA auxiliary frame '16. to the 'position shown in Fig. 2, thus'making it practicable to deposit the material'in the carquite closely tothe center thereof.' After the filling of the car from one en tothe central part is accomplished, the apparatus is moved to its original position lwli-ile entering the car-door and is turned in a direction to fill the oppositeV end of the car, when vthe operation heretofore ldescribed ".tion, which has been occupied by the loader,

` filled if desired by the direct action of the chute 89. l

The upper platform 36 occupies a position just below and in close proximity to the depending partsof-the angle-iron conadapted to catch any fine coal that may eslcape between the slats or bars connecting vthe chains of the conveyer, thus ,preventing any tine coal 4from passing downwardly and interfering with the operating parts of the machine. Furthermore, by virtue. of the arrangement of the upper run of the traveling conveyer with reference to the upper platform, the slats or bars of the conveyer are adapted to scrape any tine coal that otherwise would accumulate thereon, forwardly when the conveyer is in operation, the said coal being carried as far as the forward extremit of the main frame when it drops into t e ca'r beyond the operating mechanism of the'l loader.
