Be it known that I, RICHARD L. Lion),v citizen `ofthe United States, residing at N ew York, in the countyof New York and State of'N ew York, haveinvented certain new and useful Improvements in Ore-Distribut ing Mechanism for Charge Cars, of` which the following is a specification, reference being had .therein to the accompanying drawing. Y p r This invention relates to an apparatus for forming piles orstrata of granular or reduced material which are normally uniform in thickness or vertical dimension but which canbe optionally varied in respect to is especially designed for the handling of oreand the materials used in ore treatment, particularly the mechanism employed for loading the cars which are employed to carry charges of the component materials thatare introduced into blast furnaces.

Figf shows in top View and in section a part of a modified formof carrier apron.
The framework supporting the apparatus comprises the bars 1 and 2,' `the uprights 3,
and suitable cross bars or bracesv as at 4, these being preferably formed of sheet yor angle or channel metal- The channel bars 1 extend across a depressed. 'runway 5, in which are laid rails 6, 6 for supporting and `guiding the charge car 7. The loading'or charging element comprises the car 8 provided With axles 10 on which are mounted wheels 9.
, l1, 1l8L are shafts yin bearings 12 secured to the upper faces of the side bars 8a ofthe i920. Serial No. -3,731; "z
drum 13, 13, rigidly .secured therct'o,'thev drums being positioned equi-distant from the sidesof the car. .8.. 14, 14a are ratchet wheels also rigidly securedtofthe shafts 11, 11a. 15,15." are dogs adapted to engage with the ratchets. therdogs 'of the front'pair being pirotally secured to mounting 16y on the sidebars 8a, ,and those ofthe rear pair being mounted l on pinions 17 pivotally mounted on the rear shaft 11n. f f i' 18 is a belt or endless apron on the fdrums 13, 13a. It may bemade of any suitable material for carrying the ore which is to bev deposited in the charge car.. `The upperrun ported uponsmall rollers26, 26, mounted in bearings on side .harsg27, positioned longitudinally and fastened to the tops` of the channel bars-8a.`
Onv .the cross bars 4 are placed longitn dinalchannel irons 19 of the same length as the c hannelsl and 2.. On the bottom faces of the channels 19 respectively are secured racks 20, each adapted to engage with one of the pinions 17 on :the rear'axle 11". 21 isa pneumatic or hydraulic Icylinder in which `isfitted a, plunger connectcdby a rod 22 to the rear end .bar 8b of the car 8 `for moving it forward and backward over the runway 5 as desired.
23 is avhopper in which. the material is initially placed which is to be deposited in the charger-ar. This hopper is supported at the top by the channel irons 2, 2, and it which is open. Thebottom edge. ofthe forward wall .is cut tapers toward its lowerfend,
agent, .oil orwater, is introduced `at the outer end'of the cylinder 21, its lintiow and escape being` controlled by' three-Way `valve at 2l"L or other suitable control device. The plunger advances and pushesforward the hopper 23 and" settles upon gate 25, as descri The forwardadvan'ce. of the ca r and forward end part of the latter reaches the vertical planes ofthe outer side ofthe c lof :the outer edge c 15 engage -withthe ratchets 14 and thus pre.-y vent' the apron or lbeltfrom moving backthey carryingthe dogs lffloosely nary .would the car, because of the resistance tofthe for# v ward movement of the toprun or section of charge .car 7 or reaches the vertical lines ,of the stratum or pile to be formed, during which movement the dogs wardat the top. The a ronl under ordicircumstances, an tend' to move backward, relatively to the belt causedby the heavy'material flowingA from the hopper. Thepinions 17, however, are free to rotate `on the shafts 11 in a'counter clockwise; cli-- lre'ction and while .the car is moving forward these pinions are caused 'to loosely rotate, around, that is out of engagement with, the teeth of the lratchet wheelsll.
When the car' has reached the position lindicated by dotted lines in Fig. 1, the movement of the plunger yand the rod 22 in the cylinder 2lv is reversed, the operator, by the necessary valves, reversing the ,intakev and exhaust of vthe Huid agent; and the car orV distributin to its original position. Now the pinlons' element 8 is. drawn backward 17 byA engagementffwlth the. ratchet 20 are `causedto -rotate in a clockwisevdirection, and
the'dogs 15'3L on therear axle 11a engage with the' ratchet wheels Maand cause them to rotate the drums.I 13--j13i land-to relatively move the-apron forward. This causes the material of the stratum on the apron or beltA to be distributed over vand dropped from the front roller 13' and deposited inthe 'car 7 or on any preferred support. :As-the operative .parts act automatically a uniform-.stratum is deposited which is normally exactly simi' lar in Aits dimensions tothe stratum formed on the apron or belt." Y If it bedesired to deposit another. stratum of dimensions equal to that described above, the gate25 is allowed to remain in the position which it v has been occupying and the movements of the car 8 are repeated. If it be desired to form a .layer which -is of greater or lessvertical dimension than that of a previously formed stratum, ther` gate 25 is adjusted correspondingly and then the `car is moved in themanner above described; If it be 'necessary to form in thecar 7 a stratum which in one region is of greater depth than in another,
i this is attained bycontrolling the movements of the plunger 22 in such a way as to cause the delivery end of the apronto reapron is continued until the unless' locked wensen ciprocate "overishorterfor longer sections of lthe total pathfotthedistributor. Or use lmaybe made of' :ai power-device or motor,
supplemental those. .above referred to, by which the forward roller 13 can be rotated at will even while itsI supportingcar is relatively stationary.
I'f it be vdesired .to-pfor'mstrata, in the charge car, each composed of different material, for example, one being composed of ore and the othei'srespectively composed of l'the heat generating and the .flux-'forming ingredients, `supplei'nental sets of devices `similar to those described can'be provided Iby' duplicating the mechanismsh'own, each hopper to be' supplied with one yof the vari- 'ousmaterials j `In such casezthe charge car, after receiving one or more strata ofthe materialv inthe first/hopper, can be advanced to the' second to receive a proportionate quantity throughout they series.
In Figs. 4, 5 and 6 fied mechanism toserve as the stratum forming land distributing element. The car .8", here', is s o constructed that the upper run or section of thedistributing apron is considerably lower relatively and the several parts'are `more compactly arranged. TheA side bars 8fl of the car- 8c have the portions of a second material, and so on I have Ashown a modibetween the axles drooped down as in Fig.
4. A strong durablestratum' support 18a. is vformed of metallic carrier sections 18b (Fig. 7 fitted to chains 18c positioned along the sides. The floor parts of the sections overlap, eachthe next, andprovide a continuous floor vsupport for the ore orother material. This carrier is supported on vdrums 13",'1Sc having ratchets and dogs.- [The latter, however, differ 'from those in the construction in Figs. l, 2 and 3 in that those connected to the rear drum are mounted and operate in .a way lsimilar'to that in 'which the Aforward ratchets are mounted and operated;
f A simple device for'ei'ecting' a movement of the sectional apron 18bis combined with it; the same consisting of dogs 50 supported Yby pivots on the hopper 23, there being one of ,these in the vertical longitudinal plane of eachv of the chains 18. When the apron inthe mechanism in Fig. 4 is movedy forward with the ca-r 8", it is bodily stationary on the'car as dogs 15h engage the ratchets and prevent'any backward movement of theupper run. During such forwardr movement of the car 8c`the dogs 50 vibrate idlyfvertically as. the chain links move under them. But when the car 8c is drawn backward again by the plunger, the lower end of each dog 50 engages with the ends of the link bars or with the cross bars or pintles of the links of its chain and the chains 18c and the metal apron 18b are held4 stationary relative to the hopper; but are moved, relatively,'varound the rollers." therefore the material ofthe stratum, which was deposited on the metal apron duringy the vforward,
movement of the car 8, is now dropped over the `forward, receiving, end of the distributor and a oorrespondlng stratum. is
v formed below it, as in car 7, in the manner above described. j y Y v The apparatus in these Figs. 4, 5 Vand 6 comprises a supplemental motor 31, such as was above referred to. It is mounted on a lplatform '31 secured rigidly to the car 8c in another, the vmovement bodily, of the car 8 is stopped, and the motor 31 is put into action; Thereupon the stratum supporting apron moves around its drums'and continuesv to .deliver material until the motor is again vsto ped.
hile I have above described somewhat in detail devices which can be employed to carry out my invention itis to be noted that,
v modification can be made ,with-outdeparting from the spirit thereof. It will be seen that` the charge car at 7 is to be'regarded as ,typical of final supportsv of predetermined areas upon which the strata are to' be formed.; and also that each operativesection of the endless apron can be consideradas an initial v support for the stratum, which latter support togetherLwith the stratum are movable bodily in one direction over` ,the aforesaid final area, and furtherthat'theinitial supf port is movable bodily in the opposite direction and is also relatively movable so as to deliver the stratum to the car/6r final su port. The car-8 serves as a carrier for t e initial support, which as eze/mplified here is an endless apron that moves bodily with the carrier when the latter ,is moving inone direction, and moves both bodily -with and in relationl to the carrier rwhen the latter is moving in the opposite direction;
