CAR-LOADING APPARATUS.

To all whom it may concern:

- .w-Be it known that LRAYuoNo G.LAWRY, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car-Loading Apparatus, of which the following is a specificasuch as coal, and has for one ofits objects to provide a new and improved means for conveying and loading lump and other larger sizes of coal into the cars without breaking.

It is illustrated diagrammatically in one form in the accompanying drawlng wherein- Figure 1 is a diagrammatic plan view of diagrammatic side elevation; Fig. 3 is a detail in plan of a portion of the feeding machinery; Fig. 4 is a side elevation in part section of the parts shown in Fig. 3; Fig. 5

' Fig. 6 is a detail of the adjustable eccentric.

Like parts are indicated by like letters throughout the several figures. I

A- A are railroad tracks along which the coal cars shown-in dotted lines at A are adapted to travel.

A is a supporting frame work which carries a combined screen and conveyer chute A The chute A is mounted for reciprocation on the rollers A on the supporting framework A-,and is connected for reciprocation by means of the drive link A with any suitable source of reciprocating power. The combined screen and conveyer chute has bined screening and conveying deck along which coal or other suitable material is fed from the chute B toward the discharge end by the reciprocation of the conveyer.

The smooth conveying surfaces 13 of the conveyer deck are broken up at certain points by a fine screen 13 a medium screen B and a coarse screen B the fine screen being at the upper end and the coarse screen adjacent the lower end of the conveyer.

Application filed February 5, 1915. Serial No. 6,217.

Beneath the deck B and supported between the side walls B is a lower deck B apertured at -B B and B below the lower boundarles of the screens B B and B These apertures discharge into the chutes B B and B which are mounted for discharge into the separate cars A The spout C forms a continuation or discharge end for the conveyer chute A and is gradually reduced in cross section downwardly toward the discharge point where it discharges into an inclined chute D, which in my preferred form is arranged at right angles to the chute A The chute D is supported on rollers D which rollers ride upon the frame D and it is adapted to be reciprocated by the link D? having a strap D surrounding the eccentrlc D The chute D is apertured or screened as at D in register with the funnel or chute D discharging into a spiral screw conveyer D D is a drive shaft which drives the eccentrio D to reciprocate the chute D and thus feed the material forward down the inclined surface thereof as it is deposited upon the upper extremity by the spout C. The chute g D discharges at its lower end into the upper end of the pivotally mounted chute E.

E is a roller supporting the upper end of the chute E free to reciprocate along the frame D.

E is a supporting connection applied to the outer end of the chute E for raising and lowering it by means of any suitable tackle not here shown.

E is an eccentricon the shaft D and E r is an eccentric cam rotatable about the eccentric E and apertured as indicated to permit engagement of the pin or key E to hold the eccentric and eccentric cam in any suitable position with respect one to the other and thus form a single adjustable eccentric whose eccentricity may be varied at the will of the operator by a manipulation of the outer cajm.

E is a connecting rod having a strap Fl surrounding the eccentric cam E and pivextends back beneath the chute A and discharges adjacent the discharge end of the chute B. It passes beneath the chutes B, B, which. chutes are provided with fine screens F, F to permit the extraction of fine material and it is returned to the fine material car into which thechute B nor mally discharges.

Itwill be evident that although I have shown in my drawings an operative device, still many changes might be made both in size, shape and arrangement of parts without departing materially from the spirit of my invention, and I wish, therefore, that my drawings be regarded as in a sense diagrammatic;

The use and operation of my invention are as follows: WVhen cars are to be loaded with the screened, separated or graded material, the coal, for my device is designed primarily for use with coal, is fed to the upper end of the combined screen and con veyer chute through the spout B 'The reciprocation of the inclined chute tends to feed the coal down toward the lower end, and as it is thus fed it passes over the screen's'in the bottom of the platform as indicated. The first very fine screen takes out only the've'ry'finest particles such as dust, slack, and the like, and that being small is permitted to drop freely into the car below. The neXt screen takesout pea or nut coal,

' or' the like, and'it drops down through the chute across the stepped screen, and this also being small, each particle may be allowed to fall freely into the car without danger of undue breakage. The dust which was not extracted at the first screen, or which may have been subsequently formed by rubbing together of the particles, passes through the fine screen to the conveyer which conveys it back to the discharge point above'thefirst car. The remaining coal on the separator or conveyer passes on, part of it, such as egg coal, passing through the coarse screen. This size may be re-screened before'it goes toits car the same as the pea or the nut coal. The remainder is dis chargedas lump from the end of the chute. This coal thus finds itself upon the inclined reci'p'rocating' chute and is fed downwardly toWard' the discharge end going over the p erferation's in the bottom. These perforatiens permit a droppingput of the fine partieles: notpreviously removed or subse quently formed and these fine particles are conveyed or: discharged to theconveyer whichcarries them back to thefirst car. The coarsematerial, such as egg or coarse hemp coal, is'then discharged in a continuous, gradually" moving stream from the end of ith'e'inclined chute to the pivotally mounted chute E. In order that this material maynot be broken up and pulverized so as to produce irregularly graded and unsatisfactory car loads it isnecessary that it be gently and easily conveyed to the car without an abrupt fall. The inclined shaking feed spout E does this. As thecaris first being loaded the chute will be lowered so that it approaches the bottom of the car. As the coal piles up in the car it is neces sary to raise the chute a small amount at a time so that material discharging from the end of chute falls only a short distance.

It is evident that for different sizes of coal and under different weather conditions or conditions of moisture and the like, the relation between the inclination of the chute and the amplitude of its reciprocation will vary and it maybe necessary tochange'the stroke of the inclined chute and it therefore becomes necessary to permit the operator, who alone knows the conditions by being on the ground at the time, to make the neces sary changes in the feed, and this the opera-- tor can conveniently do by changing the position of the chute and thus its angleof inclination, and also by changing the length of stroke by moving thec'am around a cer tain. amount on the eccentric."

I claim:

1. Means for discharging" materialsan'd' the like comprising a chute havingone end pivoted and held against vertical displace' direction, a discharge chute having its axis in the same vertical plane as, and pivoted at one end, immediately below the discharge end of the feed chute, separate means for reciprocating it in a horizontal plane, means i for controlling such reciprocation and means for raising and lowering'the free end of the chute to vary its angle of inclination without longitudinally displacing it.

3. Means for conveying and discharging fragmentary materials and the like comprising an inclined feed chute and means for reciprocating it in a generally horizontal direction, a discharge chutehaving'itsaxis'in the same vertical plane as, and' pivotedl at one end immediately below' the discharge"'- end ofthefeed chute and separate'm'eans for reciprocating it in a horizontal plane.

4-. Means for conveying and discharging fragmentary materials and the like comprising aninclined feed chute and means for reciprocating it in a generally horizontal directlon, a discharge chute having 1ts axis 1n the same vertlcal plane as, and pivoted at one'end immediately below the discharge end of the feed chute, separate means for reciprocating it in a horizontal planeand means for raising and loweringthe free end of the chute to vary its angle of inclination without longitudinally displacing it.
