T all whom it may Vconcer-1t:`

Be it known that I, J AMES L. LAMB, of Trinidad, in the county of Las Animas and State of Colorado, have invented a new and lmproved Coal-Loading Apparatus, of which the following is a full, clear, and exact description.

, This invention relates to an apparatus for loading coal into cars, and particularly for loading coal into box-cars, the invention ernl hodying a trestle-way or support on which a carriage is mounted to slide toward andA from the car, the carriage supporting a conveyor mounted to turn and to be moved vertically, so that it may he adj usted to properly direct the Icoal.

This specification is the disclosure of one form of my invention, while the claims define the actual scope of the invention.'

Figure l is a side elevation of the invention. Fig. 2 is a plan ,View thereof with parts broken away; Fig. 3 isja section taken vertically through the carrer-platform and longitudinally with the carriage. Fig. 4 is a section of the same paris on a line transverse to the carrier; and Fig. isa plan view of the invention, y showing it in connection with the car.

vwith hearings l5,

The trestle-work 6 has two horizontal rails 7, on which run the wheels 8 of the carriage 9, and mounted on the trestle and extending longitudinally with the same is a shaft 10, driven continuously by a suitable source of power. (Not shown.) Splined on the shaft 10 is a sleeve 1l, at one end of which is a bevel-gear 12, and at the other end of which is a bevel-gear A.. The carriage 9 is provided in `which the shaft 10 is slidably held', such hearings moving with the carriage. The sleeve ll is locatedvbetwee'n 'f wo of the bearings l5 and is adapted to slide with the carriage he moved'v to cause shaft 19,.hel`d in bearings 20, iixed tothe cary the sleeve-ll to anginterniediate 'position the gears l2and, "14 may he' placed-s0 that` neither of the said gears and to turn continuously. with the shaft 10. A lever 16 is vmounted oni. j the'carriage andconnected by a collar 17. with the sleeve 1,1, so thatupon swinging the. lever the sleeve, with its gears l2 andl/l, may, either of the gearsto en-f gage with va hevelgear 18, mountedf'on theA "posite the end having'the gear 3l.

will be in engagement. with the gear Fixed tothe shaft 19 is a spur-gear 2l,vwhich turns with' the: shaft 19 and moves with the carriage' 9, and which engages 'a rack' 22, fixed to the y trestle way 6.

revolution of the shaft lO may,when the gears 12 and 14 are properly adjusted, be caused to revolve the shaft 19,.and .consequently drive the carriage 9 along the trestle-way therack 22.

Mounted on the outer end-of the carriage,y

By these means ythe f 6o through the medium of the spur-gear 21'a'nd.-

9 4by means of'a ilangedhuh 23, arranged to turn in' the carriage',is a double-faced bevelgear 24,-frpm the upperface of which'projects a Vhuh 25, on' which a bevel-gear 26 is revolubly mounted, and iXed to the top of the bevel-gear 26 aretwo bearings v27 in which is mounted a revoluble shaft 28, which carries loosely the arms 29 of the conveyer-franie 30,

by which means the conveyeieframe is supported. vThe shaft28hasa bevel-gear 3l fixed thereto, vof the bevel-gear through an'opening in the gear 26, as shown best in' Fig. 4. The lower part of the'gear 24 meshes 'with a `loevel-gearv 32', splined on the shaft l0 and connected by a link 33 with a` lever 34., which is fulcrum'ed on the carriage whichimeshes `with. the upper part 24, the gear v3l extending- 9. The lever 34 in turn is connected with'a link 35, which runsrearwardly, and is con# nected to alever 36, mounted on the carriage' 9. By these means the gear 32 may-be moved in and out of engagement with thelower part of the gear 24', and -thus the revolution of` the shaft 28 may `he regulated. The conveyerframe ing around couveyer-rolls 38, held. by the frame 30. Thein ner rollf38 is provided with a sprocket-wheel over whichpasses va chain 39,

chain also passing'downwardly over a jsprocket-wheelYon the end of' the shaft 28 op- Bythcse means thecenveyerlmay be driven ,'such vv'i'nfc'ivement being controlled by the hand-le- A4riage 9 and lcarry at their upper ends antifrictionf-i'ollers 4l,which bear down on theupperfsnrface of the gear 26 to prevent the'displacement thereof, but at the same timer mit the .gear -28 to revolve. I

30 carries an endless conveyer 37, passy Braoketsf() are attached to the carf y connected wi t-h each other by The gear 26 is driven, so as to swing the carrier or conveyer, by means of a bevel-gear 42, meshing` with the gear 26 andV carried on a revoluble shaft- 43, mounted on the carriage 9 and running rearwardly thereon. The shaft 43 isA provided 4with'a worm-`whee144 at its rear end, which meshes with a worm 45, fast to @perpendicular spindle 46,;l`nounted on the carriage 9 and'having a hand-wheel47 at its .upper end.` f

For adj ustng the inclination 'of the carrier or conveyer-frame I attach two arms'48 to theA sides of the conveyer-frame, such arms being a transverse bar 49. -Connected with the barV 49 isa cord 50, which passes down around a pulley 51,mount. ed on the top. ofthe gearv 26, and which next passes approximately.horizontally around a pulley 52, carried by the hub 25 of the whe-el 24. rom the pulley 52 the cord 50 passes downwardly through the hollow middle portion of the hubs 25 and23 and around a p'ul' 'X ley 53, carried by a bracket attached to the hub 23 and projectingdownwardly therefrom. From the-pulley 53 the cord 50A runs rear(- wardly and is attached to the arrn54 of a" toothed sector 55, pivoted on the arm 56 of a bracket 57, in turn carried by the carriage 9. The bracket 57 has .a bearing in its top, in which bearing is mounted a spindle 58, carrying at one lend a hand-wheel 59k and at the other end a worm 60, meshing with the sector 55. By means of these devices the cord may be drawn in or slacked off, thus raisingvor lowering the carrier-framathe same being connected to thearms 29 on the shaft 28, before described;

` intothe middle of the car'.

In using the invention the carriage 9 is projected along the trestle-way 6 until the outer end of the carriage extends into the car 61. (For :which see Fig.' 5.)l Meanwhile the shaft 43 should have been operated to turn the gear 26, and thusadjust the carrier, so that it will deliver the coal into one end of the car. The coal is fed to the carrier 30 in the direc` tion opposite that in which the carriage 9 is located, such feeding being done by means of a chute 62. This arrangement permits of filling one end of the car with, coal, whereupon the carriage 9 may be withdrawn and the c hute 62 permitted to discharge the coal Meanwhile the carriage 9 may be moved back and the carrier '30 shifted so as to project into'the opposite end of the car, and upon receiving the coal from the clute 62 thecoal will fill said opposite end. All of the elements ofthe apparatus are directl y under the control of the operator, and by means of the apparatus it is possible to quickly and conveniently coal box-cars kand other rolling stock.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A 1.A In a loaderfor. box-cars, the combina.-l
