(hm form of {an ire wt. forth in the following: H lvI'Y-IHP helm: had to the (H-Win1 variation may he made in tho-details of the adjust the tension of the chains 3 in a manner common in conveyor practice. At the lower or receiving end of the conveyor the chains 3 ass around a stationary cross bar 14 to which is attached two guide bars 15 adapted to en age the rollers 16 of the chains 3 to gui e them from the lower to the upper run of the conveyer. Attached to the side plates 1 of the inclined and upper horizontal parts of the conveyer trough, b means of strap bars 17, are flaring s1 e plates 18 'whic serve to prevent the overflow of material from the conve er trough. The lower horizontal part 0 the conveyer trough is provided with removable lates 19 having stiffening bars 20 the pro- Jecting ends of which are ada ted to be in serted. in sockets 21 attache to the side plates 1. At the forward end of the conve er the bottom plate 7 extends on either aid; of the conveyor trough and is bent upward to form a skid shoe 22 BA pte'd to slide readily over the floor of the mine,. Near the forward end of the conveyor is rovided a cross bar 23 projecting at either side to form handles 24 convenient for lifting and moving the forward end of the conveyor. At-

tached to the conveyer trough, equidistant from its ends, is a structural framework 25 having horizontal members 26 which are adapted to serve as a supporting base for the conveyer, as will be hereinafter set forth.

Mounted in this structural framework 25is an electric motor 27 by which power is supplied to actuate the conveyer. The armature pinion 28 of the motor 27 engages factorily drive the chains.

a spur gear 29 which is mounted upon the cross shaft 30 and is adapted to be connected thereto by a friction clutch 3,1, of the well known multiple disktype, having a controlling hand wheel 32 by which the friction elements of the clutch may be readily engaged .or dise ed. Attached to the opposite end of the shaft 30 is a spur pinion 33 which engages 'a spur gear 34 fixed to a second cross shaft 35. The shafts 30 and 35 are journaled in bearings 36 and 37 formed in the extending'arms 38 of the'motor frame castin =Attached to the shaft 35, between the arings 37, is a sprocket wheel 39 which is connected through the chain 40 with a similar sprocket wheel 41 attached to the driving shaft 42. The driving shaft 42 is journaled in bearings 43 attached to the structural steel framework and is provided with two s rocket wheels 44 the rims of which extend throu h convenient slots 45 1n the bottom plate% and engage the chains 3 to drive them. The bottom plate 7 is chrved downwardgly at 46 to form" loops in the chains 3 aflor ng a sufficient contact, with the sprocket wheels 44 to satis- 47 is a conductor cable, extending from a source of electric supply through which current is supplied to actuate the motbr 27. A suitable switch 48 is provided to control the operation of the motor.

The conveyer member as above described, constitutes a self contained structure which, when used in conjunction with the auxiliary parts to be hereinafter described, may be easily handled by the miner and his helper and maven about the mine and so positioned that its receiving portion will be convenient f5 to material at any part of the working face, and its delivery and above the car which is to be loaded. As a supporting base for the. above constituted conveyer member I ha e provided a skid rail 55 adapted to be horizontally supported transversely of the mine room, and to lateral movement toward and from the ile of material which is to be loaded. T e horizontal members 26 of the conveyer structure bear upon this skid railasr 55, the weight being so distributed that the receiving end of the conveyer will rest lightly u on the ground. The skid rail is formed of a suitable channel bar the flanges of which are turned upward toengage the lug 25 attached to the underside of the framework 25 to prevent longitudinal movement of the conveyer transversely of the skid rail. The web of the skid rail 55 is perforated at spaced intervals with apertures 56 into which the end of a pinch bar may be inserted to pry the conveyer frame along the skid rail to the desired position. One end of the skid rail is supported during the operation of the machine upon a truck having a platform 50 supported upon axles 51 and wheels 52 adapted to travel along the rails of the mine track.

The end of the skid 55 remote from the truck 50 is supported upon a horizontal rail 57 built up 0 two steel bars 58 secured together -in spaced parallelism by suitable space blocks 59 and rivets 60. xtendin between the bars 58 near each end of the rail 57 are jackposts 61, of the type commonly used in mines, the lower ends of which rest on the floor of the mine, and have screw threaded extensions 62 adapted to be forced against the mine roof by the hand wheel nuts 63 to hold the jacks securely in place; 113i Near each end of the supporting fail 57 is an aperture ada ted to registerwith any of a plurality of apertures 64 spaced lon tudmally of the jack post 61 through which the pins 65 may be thrust to "support the rail 57 at the esired elevation above the floor of the mine. When being transported from one part of the mine to another; the conveyer rests u n the'truck platform 50' its length are lel with the track, as shown in 'Fig. 8,t e rear the orward ends of the members 26, elevates the receiving end of the conveyer clear of the trackto ermit travel therealong, as illustrated in ig. 7. Upon arrival at the working place theforward end of theicon- 5 veyer is lifted by the helper, as shown in Fig. 9, to allow the miner to remove the block 54 and to insert the skid rail 55 beneath the member 26. The supporting rail 57 is then attached to the" jack sts Gl at [0 the desired position above the fiiiiir of the mine and the posts are. tipped as shown in Fig. 10, to allow the placing of the rail 57 under the end of the rail 55, after which.

the 'ack posts 61 are straightened up and the, hand wheels 63 adjusted to force the upper post sections62 against the roof, as shown in Fig. 11. The conveyer is then slid along the ,skid rail 55 to such position that the receiving and may be laced near to the material which is to be ended, and the delivery end above the car 66 u on the track in the rear of the machine. he removable side plate 19 is then placed at whichever side of the conveyor is convenient to the operator, the motor is started to drive the conveyor, and material shoveled upon the forward receiving section to be carried upward and rearward and dis charged into the car. When the material within convenient-reach of the operator has been loaded the conveyer will be moved along the skid 55 to bring its receiving secdistance of other matetion within shovelin rial and the operation continued as before. Should it be desirable to move the conveyer forward into more convenient reach of the material, the skid rail 55 may be moved longitudinally of the supporting rail 57 and the truck50 advanced along the rails 53 40 until the desired position isreached as illustrated in Fig. 1a and Fig. 13. As soon .as the car is loaded the motor is stopped, the car removed and an empty one set in its place. During the interval of changing cars material may be shoveled onto the receiving section, of the conveyer and moved rearward! by successively starting and stopping t e motor, until the trough is full. The conveyer thus becomes a reservoir having a capacity suflicient, under normal conditions, to keep the shovelers continuously busy. This material will be immediately delivered to the (lar when it is ready for loading and the oonye er allowed to run until the car is fully Ida ed.

When the machine is to be moved to another working place, the conveyer is moved longitudinally of the skid rail 55 to the center of the truck platform 50 and turned longitudinally of the mine track. The he! er then seizes the handles 24 of the cross )ar 23, lifts the forward end of the conveyer, allowing the frame 25 to heel upon the plat form 50, as shown in Fig. 9. The Skid rail 55 is then withdrawn, the block 54 replaced and the machine lowered into position for traveling as shown in Fig. 7. The skid rail 55, the supporting rail 57, the jack posts 61, and other paraphernalia are loaded upon the truck, or the conveyor trough, and the machine is ready for travel i,

The present mechanism has all of the ad vantages incident to the loading mechanisms heretofore made, each of which has an elevating conveyer that is mounted on a vertical axis which is relatively fixed in relation to its supporting truck. All of the earlier mechanisms within this class of conveyors have been characterized by the such a relatively fixed verticalpivot. And, because of its presence the receiving part of the conveyor was held to an arc line which was fixed in relation to the truck, and hence the conveyer had to be very long in order to reach to points laterally remote from the truck, and the truck had to be repeatedly bodily moved forward and back ward.

lVith a mechanism like the present one there are a large numbei' and a wide variety of curved paths throu h which the front end of the elevating ant conveying element can be shifted both laterally and forward and back without moving the truck support. The lug 25* and the guide 55 "with its flanges, serve as a pivotal or hin ing mechanism for the conveyer frame. his hinge mechanism is such that its axis can be shifted laterally without requiring any movements of the truck. A slight movement of the pivot device is multiplied into a long moyement at the receiving end of the elevator, and this is done without materially shifting the rear end of the conveyer in relation to the receiving car. And, again, the pivot device can be moved forward or backward either by moving the outer end of the guide skid 55, or by sliding the inner end of the guide forward or backward of the car or by adjusting skid as desired. And. as with earlier devices there can be longitudinal adjustment by moving the truck bodily forward or back. But, as will be seen, the truck, at times, when the elevator is in operation is serving merely as a support which is companion to the outer support 58, and other supports for the inner end of the guide can, if desired, be substituted.

.Tho pivot, or point of vertical the elevator frame, can be positioned at a place very remote from the truck and this can be done upon either the right side or the left side of the latter.

I, for brevity, herein refer to the working element of the mechanism as a self consupport for resence of both ends of the guide tained conveyerl, meaning thereby that this element comprises its own independent frame, an endless conveyor of suitab e form, mounted on the frame, a trough or holder correlated with the conveyer and also on the frame, a motor and motor support forming part of or rigidly connected to the conveyor frame, and power transmitting devices supported on the frame and interposed between the motor and conveyor, all these making a unitary structure which is readilyseparable from the other elements. This element,

ondary support between the primary support and the conveyor. The primary support is, in the construction shown, composed of two parts, one being a truck or car at one end of the appa 'atus, and the other being posts or rails at the otherend. The secondary or intermediate support is, in relation to the points of delivery of the material and to the points where the load is 3 received, movable universally, being without rigid engagement with the primary support, that is, it can slip bodily transversely at any time, or can slip bodily forward or baclc ward at either enil or both ends. The pri mary support, similarly, can, at either of itsends or at both ends, be moved backwar or forward relatively to the secondary sup port. And the conveyor itself can be moved transversely independently of the secondary support and, together with it, can be moved in either direction, transversely, or forward or backward, in relation to the primary su ort.

mechanism is therefore readily distinguishablc from those in which the conveyer element has been in some way positivelygoverned in its movements by the truck mechanism, or by a frame connected therewith.
