This invention relates to improvements in conveyers, and more particularly relates to a new and improved means for continuously transferring loose material from a main line conveyer into a 1 train of mine cars with a minimum amount of spillage.V

The principal object of vide a novel form of material transferring means for continuously transferring material from the discharge end of a main line conveyer into ay traveling trainof mine cars, which consists in a relatively short transfer conveyer mounted beneath the discharge end of the main line conveyer and extending transversely thereof ina direction parallel to a mine trackway, for receivingmaterial from said main line conveyer and selectively transferring it from either of its ends onto mine cars on said trackway, together with an efficient and novel form of rapidly reversible drive 'connection from said main line conveyer to saidA transfer conveyer, designed to facilitate theloading operation and to minimize the spillingof material from the ends of the cars during loading. t

Amore specific object of my invention is to provide a transfer conveyer .beneath the discharge end of a main line belt conveyer .and to drive this transfer conveyer from the belt conveyer through a rapidly reversible drive connection including a plurality of constantly meshing gears, and a plurality of friction disk clutches, for connecting said gears to drive said transferV conveyer in reverse directions without reversing the direction of travel of said main line conveyer, so said transfer conveyer may continuously load a train of cars traveling along a trackway, from either 0f its ends, without spilling material at the gaps between the cars.

Other objects of my invention will appear from time to time as the following specification pro` ceeds and with reference to the accompanying drawings wherein: f

In the drawings,.the embodiment of my inven-` Y tion illustrated isjshown as including a main line lconveyer ylilextending along a mine entry and having a transfer conveyer I l at its receiving end, extending transversely. ofsaid. main line conveyer, for loading material into mine cars I2, i2 onatrack .13, disposed therebeneath and extendoftravel 4of said transfer conveyer. g

4.The main line conveyer IB is herein shown as beinga well-known form of belt conveyer includingia belt l movable `along ar frame l5 and around an idler`l6,.mounted at the discharge end offsaid frame. -Said idler is mounted on a transverse shaft Il, suitably journaled at the discharge end'of said frame and having a sprocket lfkeyed at one end thereof and forming a means forl driving the transfer conveyer H from said main line conveyer, .as will hereinafter more clearly appearA asthis specification proceeds.

The transfer conveyer Il extends transversely of andlissuspended from the mine roof and supported on'thedischargeend of the frame l5, vand extends in a directionparallel to the'mine track I3,- for discharging'mate'rial into the mine cars l2, l2 from either'of fits ends as said mine cars travel alongsaid track..A Said transfer conveyer and a laterally spaced outer side wall 2| (see Figure 2). :A central stiifening and connecting member 22 of saidframe connects the side walls 20 and 2l together and extends laterally beyond Said connecting member has a depending leg-23. of a T-shaped suspending member 24 seCuredYtheretO.v The cross of the T of said suspending member has a pair of

angles

25, 25 secured thereto by .bolts 6, 26. Said angles extend upwardly from said member, adjacent opposite ends thereof, and may be suitably connected to thereof supports of the mine at their upper ends, to form a support for the outer end of said transfer conveyer von said roof supports. SaidA bolts also extend through the upper side of aside wall 21 of a pan 28 of therconveyer to connect the upper .end of said side wall to said suspendingmember. Said side wall extends vertically downwardly from its upper end, for a por-- tion of its height, and is then inclined inwardly and downwardly to the inside of the side wall 21, to form a retaining side wall for the transfer conveyer and to deflect material thereon. Said side wall then extends along the inside of the upper portion of the outer side wall 2|, and turns horizontally inwardly to. form a bnttozn 29 oi said.. transfer conveyed 'Ima-opposite side offsaidipam extends upwardly along the inner sidewall 2'0't0` the top thereof and is then inclined in an upward. direction towards the lower portion of the idler I6, to form an opposite retaining wall fontsaidicomveyer.

It may further be seen that the ability to instantaneously reverse said transfer conveyer under thefcontrol of the operator,.in a simplified manner, insures full and continuous loadingv of the car passing beneath said transfer conveyer, with no spilling of material as thegaps between adjacent' ends -of the. mine cars .pass by either end of said transfer conveyer,'and with no stopping of. the main line conveyer or of the train of minecars, during the loading operatiom While I have herein shownand describedione form in which my invention may be embodied, it
