Application filed March 21,1908, Serial No. 422,488. Renewed April 22,1910. Serial No. 557,074.

To all whom it may concern:

Be it known that I, WVILLIAM VVneLEY, a citizen of the United States, resldlng at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful lmprovementin Loading-Machines, of' which the following 1s a speclficatlon, ref- 7 erenco being had tothe accompanying draw-v While the machine is primarily intended for' use in such workings, it may also be used in open situations for. the loading and digging of coal, ores, gravel, sand, earth, and other loose materials.

The improvement may be embodied in a variety of forms. In the particular form herein described, the invention is embodied in a machine comprising (1) a frame mounted upon supporting wheels for the moving of the machine to and from the material to be loaded; (2; an endless conveyer extending lengthwise of said frame and high enough at the rear end to discharge on a wagon, car or otherwise; (3,) a shovel or scoop sup ported at'the front end of said frame and so controlled as to move forward with its nose upon the floor or ground and take a load, lift the load and move it rearward and discharge it upon said conveyer.

Any suitable power isto be provided for operating the conveyer and the scoop or shovel. In the form illustrated by the draw ings, an electric motor is mounted upon said frame to furnish such power.

In .the accompanying drawings, Figure 1 is a side elevation of an apparatus embodyline 33 of Fig. 2, looking in the direction of ing my improvement; Fig. 2is a plan of the same structure, DOItIOllS being broken away; F1g. 3 IS a longitudinal uprlght section on the the arrow; Fig. 4: is a transverse uprightsection on the l1ne 4-4 of Fig. 1, looking in the direction ofthe arrow; Fig.5 is a section on the line 5-5 .of Fig. 2, looking in the direction of the arrow; Fig. 6 is a detail plan of one of the rear corners of the rear conveyer;- Fig. 7 is a horizontal section on the line 77 of Fig. 1; Fig. 8 is a detail, upright section of the scoop-supporting mechanism.

Referring to saiddrawings, 1, 1 are lower side rails of the frame. Therea-r ends of said rails are connected by a cross-rail, 2, and the front ends of said rails are connected by a cross-rail, 3. Said rails'are also connected by intermediate crossrails, 41, 5,- 6, and 7. From the rear end of each side rail rises a corner post, 8. Said'posts are inclined toward each other. (see Fig. 5). On the front end of each of said side rails is a plate-form corner post, 9. A brace, 11,

extends from the up er end of each rear corner post, 8, oblique y downward and forward to the adjacent lower side rail, 1; and a similar brace, 12, extends fromeach'corher post, 9, obliquely downwardand rearward to the adjacent lower side rail, 1. To the front portion of the lnner face of each corner post,-9,- is riveted or bolted an upright channel piece, 13. Above andparallel to each side rail, 1, is an upper side rail, 10, having its rear end secured to the adjacent'corner post, 8, and having its forward end secured to the inner web of said channel piece, 13, said upper rails being nearer to each other than are said lower rails. And each upper side rail is secured to the channel piece, 13, only a little way above the front end of the lower side rail and extends thence obliquely upward and rearward and then forms an angle and extends rearward to the height of the rear corner post, 8, and extends thence rearward any desired distance beyond the rear corner post. From the angle in saidupper side rail, a supplementary side rail, 14, extends forward horizontally to the inner web of said channel piece, 13, and is suitably secured thereto. And each such-supplementary side rail, 14, is joined to the main up per side rail, 10, by means of a gusset plate, 15. Each upper side rail is of channel form, the flanges being turned inward to form ways for carrying the conveyer belt, as will be hereinafter described.

' In line with each upper side rail is a bearing, 16, in said channel piece, 13, and a transverse horizontal shaft, 17, rests in said bearings. At the extreme rear end of each upper siderail, 10, is a bearing, 18, and a transverse shaft, 19, rests in said bearings.

On saidshafts, 17 and 19, are sprocket B'y' inclining the forward the shaft, 19, and, through the latter, the

conveyer belt. Said sprocket chain passes over two idle wheels, 23 and 24, and around a sprocket wheel, 25, on a counter-shaft, 26, mounted in" bearings, 27, on the frame of the-electric motor, 28, which motor frame is seated upon the intermediate cross-rails, 4 and 5. Power is im arted from said motor to said countersha t, 26, by means of a spur gear wheel, 29, on the motor meshing with a larger spur gear, '30, on'said shaft. On each upper side rail,'10, are mounted outward directed brackets, 31, supporting sloping side plates, 32, which form the sides of a trough of which the conveyer belt is a. traveling bottom.

We now come to a description of the scoop or shovel and the mechanism for supporting and actuating the same. 1 To the front face of each channelpiece, 13, is bolted or riveted an elbow piece, 33, the upright arm of said elbow piece being directed upward.- A little way below said piece, 33, is a horizontal member, 34, separated at each end from the elbow piece, 33, by spacing blocks, 35. Through the front spacing block and the adjacent ends of the member, 34, and the elbow piece, 33, passes a binding bolt, 36; and a bolt,,37, passes upward through the rear endofthe member, 34, and the adja- 1 centspacing block, 35 and is tapped into the adjacent portion of the elbow piece, 33. In this way a rectangular opening constituting a slide-way, is formed for a sliding block, 38. Each such block has a groove, 39, above to receive the elbow piece and a groove, 40, below for receivingthe' horizontal member, 34. By this. means, said blocks are effectively confined and limited to a horizontal movementparallel to the length ofthe machine, and such movement is without rotation of-said block.

' At the inner side of each member, 34, (the side directed toward the other member, 34)

a rigid ear,'41, extends downward from the "adjacent slide block, 38;, and in each such ear is a horizontal transverse bearing, :42. A transverse horizontal shaft, 43, rests in I said bearings, its ends projecting through said bearings and supporting segmental gears, 44. rectangular bar, 45, has journals, 46, at each end extending through bearings, 47, in the slide blocks, 38, and projecting -far enough to support segmental gears,

given a partial rotation upon the axis of said shaft,45. But such movement is only a partial rotation limited by the extent of engagement between the segment gears, 44 and 48approximatel a-half circle. When said segment gears iscngage, the shovel falls back to its original position by gravity. In addition to said partial rotation upon the axis of the shaft or bar, 45, said shovel reciprocates horizontally by the reciprocation of the .slide blocks, 38, whereby the shaft or bar, 45, is carried forward and backward. Said blocks .are reciprocated by mechanism as follows: Adjacent one of the segment gears, 44, on the shaft, 43, at the rear of the scoop is a bevel gear, 51, surrounding ;said shaft; and said bevel gear meshes with another bevel gear, 52, on a telescoping shaft, 5.3,whichis parallel to the length of the machine and rests at its front end in a bearing, 54, in the adjacent channel piece, 13,-and at its rear end in a bearing, 55, and is loosely surrounded at its rear end by a bevel gear, 56, meshing with a bevel gear, 57, on a counter-shaft, 26, adjacent the electric motor, 28. A clutch, 56, on the shaft, 53, serves to engage the bevel gear, 56, to. said shaft (Fig. 2 The bevel. gear wheel, 52, and the portion of the shaft, 53, thereto attached are held in position by a bearing, 62, in a curved rearward extension of the ear, 41, on the adjacent slide block, 38. By means of said gears and telescoping shaft, the shaft is continuously rotated clockwise as viewed in Figs-1 and 3, and with each rotation of said shaft the segment gears,

- 44, on said'shaft engage the segment gears,

48, onthe shaft or bar, 45, and impart a partial rotation to the latter, as already described. On each end'of the shaft, 43, is a rigid crank, 58, the outer end'of each of which is coupled at 60 to one end of a link,

.59, the other end of which link is journaled at 61 tothe frame of the machine. Said link is therefore free to oscillate in an up right plane with the point, 61, for a center; and said links restram the rotation of the cranks, 58, to such extent and in such manner as to cause a reaction upon the shaft, 43, and through the latter upon the slide blocks, 38, to compel the latter to move horizontally between the horizontal members, 34, and the elbow piece, 33. In other words, said cranks tend to impartto. the shaft, 43, an orbital movement as a reversal of the orbital move-' ment of the outer ends of the cranks; but

said orbital movement is modified to a .reciprocatory movement by said horizontal member, 3t, and the elbow piece, 33, the oscillation of the links, 59, compensating for the absence of the orbital movement of said shaft and the. consequent rotation of the outer ends of the cranks upon a fixed line. During such reciprocatory movement of the slide blocks, .38, the telescoping shaft, 53, shortens and lengthens to the extent of the reciprocation of said blocks. l

' The purposeof the bodily reciprocation of the scoop is to bring the nose of the scoop in front of the material beneath which the scoop is to pass. The movements are so timed as to bring thescoop to its rearward limit when the nose of the scoop reaches the low portion of its orbit, and to bring said nose to the high part of its orbit when the rear limit of reciprocation is reached, in order that the'scoop may then be so tilted backward as that the material thereon will move rearward out of the scoop upon the conveyer. I

Provision is also made for propelling the machine by the power of the electric motor,-

28, to take the machine from one working place to another or to propel the machine forward for its work. For this purpose, a counter-shaft, 63, is seated in bearings, 64, parallel to the countershaft, 26, and provided with a spur gear wheel, 65, meshing-with a spur gear wheel, 66, on said counter-shaft,

, 26-. On the counter-shaft, 63, is a reversing gear member, 67, comprising two bevel gears directed toward each other, said member being keyed for sliding upon said shaft and to rotate therewith. A bell cranklever, 68, engages an annular groove, 69, 'on said member, 67 whereby said reversing member may be reciprocated by the operator of the machine.

A shaft, 71, is mounted in bearings, 72, parallel to the length of the machine and on the rear end of said shaft is a'bevel gear, 70, standing between the bevel gears of the reversing member, 67. said shaft is a worm, 73, which. engages a worm gear wheel, 74, on the axle, 75, and said axle rests in the supporting wheels, 76, and said wheels rest on the desired form of track. The shaft, 63, and the reversing gear member, 67, receive motion from the motor, 28, and either one of the bevel gears of said member may be made to engage the bevel gear wheel, 7 O, or

said reversing member may be put into such the shovel and the conveyer and the forward On the front end of round or any suitable car, so that the scoop may be given a sidewise reach for the purpose of operating over a wider area than is possible when no lateral movement is made. Such a car and jib are shown in my application Serial N 0. 381,624, filed in the United States Patent Oflice July 1, 1907.
