to be adapted to be moved into and out of clutching engagement with a clutch element [rigid with the gear 10. For this purpose a system of levers may be employed (see Fig. 7) which connect with a shifting lever 12 for simultaneously throwing said clutches in and out. lVithin suitable pedestals carried by the main frame 1 are journaled a pair of parallel shafts 13, to each of which is keyed a spiral gear 14 meshing with-a spiral pinion 15 freely rotatable on the drive shaft 8. A clutch 16 splined to the drive shaft 8 is adapted to be shifted into and -out of clutching engagement with the pinion 15 by a lever 17, so that the shafts 13 may be driven from the drive shaft when desired. Adjacent the upper end of each shaft. 13 is pivotally mounted a supporting plate 17, which is provided with a depending bearing portion 18 journ' aled in a 'ecting laterally from the upper end of a rigid pedestal 20. To the swinging end of each supporting plate 17 is pivoted at 21 a lower chute section 22,

said chute sections being constructed and arranged to provide a central conveying channel when in lateral abutment with-each other. Slidably mounted on each lower chute section 22 is an upper chute section 23. For this purpose (see Fig. 8) .is provided with an outer eral flange is provided lat- 24. while each upper section 23 with a depending. flange 25 rest- 22. 'Each upper section is moreover provided with a slideway 26 for slidablv engaging the flange 24. At the upper end of each vertical shaft 13 is rigidly mounted a driving sprocket 27 which drives an endless chain conveyor 28 traveling through each lower chute section, each of said lower chute sections being provided at its lower forward end with a sprocket wheel 29" (see Fig. 2) for mounting the lower end of the conveyor. Adjacent the pivotal support 21, and driven by the conveyer 28', is a sprocket wheel 30 (see Fig. 1) keyed to a short shaft- 31 upon'the upper end of which is keved a second sprocket 32 for driving an endless chain conveyer 33 in each upper chute section, each of said conveyors 33 being supported at the outer swinging end of its chute bv means of a sprocket 84 (see Fig. 2'). Said sprocket 34 is journaled in a scoop or shovel 35 pivoted at 3G to the forward end of each upper chute section, said shovel being providedfwith a. rear- Ward-1y projecting arm 37, between which each lower section 22 and the lower end of the chute section extends a tension member 38 which tends to maintain the shovel 35 in-alinement with the section, but also permits said shovel to be deflected so as to lie flat upon the floor ofthe mine, or other place where the machine may be in use.

Referring more especially to Figs. 9, 10, 11 and 12,'means for moving each upper chute section over the corresponding .lower section is provided by a camshaft 39, which may be oscillated upon its own axis by means of a crank arm 40. On the shaft 39 are mounted three cams 41, 42 and 43. these cams being operably related respectively to clamping arms 44, 45 and 46. Each of the clamping arms is provided with a strap 47 (see Fig. 10) which extends around and is moved by its particular eccentric. such as 43 in Fig. 10. 'The clamping lever 44 is adapt-.

ed to impinge upon the bottom of the lower chute section 22 in such manner as to lock the upper and lower sections rigidly together. The clamping lever 45 is provided with a lateral extension 48 which is adapted to be moved into clamping engagement with the downwardly and forwardly moving portion of the conveyer 28 to move the upper section forwardlv. The clamping lever 46 is provided with a lateral extension 49, which is adapted to be brought into clamping engagement with the upwardly moving portion of the conveyer 28. Eccentrics 41, 42 and 43 are set at such angles as to permit of only one of the clamping levers being operative at the same time.

' A spring such as thatindicated at 100 in Figs. 1 and 12, may be employed as a centering device so that when the crank 40 is moved in one direction the spring will be stretched, and when moved in the other direction it will be compressed. In either case when the crank 40 is actuated to release the cams the spring. will assist in restoring the crank and the cams to initial position. The eccentric cams may be variously arranged, and if desired, the crank 40 may occupy a substantially horizontal position ora position in a plane parallel to that of theconveyer-trough to. which it is connected. If

'the latter arrangement is used the spring 100 would act to hold the crank arm in its initial position and would be stretched both when the 'crank arm is moved up and when it is moved down. that is, to the vertical position shown in Figs. 9 and 10. When the 'friction ofthe'eams is sufiiciently released the spring could be relied upon to bring the cam mechanism'back to central or initial position, or in such position that the conveyer chains would be free to move, as desired.

Referring more especially to Figs. 2 and 6, suitablemeans for breaking down the material to be excavated is provided in the form of an automatically operated pick 50,

which in the embodiment shown is reciprocably mounted in a housing 51 and connected by a pitman 52 with a crank shaft 53,- said crank shaft being provided with a bevel gear 54 driven by a driving pinion 55 keyed to the upper endof a shaft 56, said shaft being driven from the conveyer 33 in the upper chute section. Each of the automatic picks is slidably mounted on either of the upper chute sectli ons and may be moved along or rigidly c amped to the section upon .whichit is mounted by being rigidly secured to eitherthe downwardly or upwardly movingportions of the upper conveyer 33,. or to the flange 57 of the upper chute section. For this purpose a cam shaft 58 is provided with eccentric cams 59, 60, 61, which may be successively brought into clamping engagement with the flange 57 and. the two portions of the conveyer 33 respectively. As shown in Fig. 8, the pedestal upon which the pick is mounted is provided with a broad .flanged face 62, over which bothportions of the conveyer 33 are driven so that when either of the cams 60 and 61 are moved into clamping position} the conveyer is clamped I between the base flange 62 and the eccentric cam, such as 61, as shown in Fig. 8.- The shaft 58 is provided with a crank handle 63.

Referring now to Figs. 1 and 2, means for raising and lowering the chutes and. conveyers is provided by oscillatable arms 64,

which are keyed to a horizontal shaft 65 having a centrally disposed worm gear 66. Meshing with the worm gear 66 is a worm adapted to. be brought into driven connection therewith by means of a clutch 68 whichis splined on said shaft 8. (See Fig. 7.) A shifting lever 69 serves to shift. the clutch 68 so that the arms 64 may be raised andlowered atwill. The outer end of each of said arms 64 is provided with a rounded protuberance or extremity 70 which abuts against the bottom wall of I section under which it is disposed. Journaled within the forward end of each arm 64 is a guide pulley 71 'overwhich passes a flexible connection or cable 72, each cable being connected to a short arm or bracket 73 projecting from the adjacent under chute section. The cables 72 are Wound in op'posite directions about a, drum 73, which is freely rotatable upon the forward axle 2 of the truck. Said drum 73 is provided with a rigidly connected worm gear 74, with which meshes a worm 75keyed to' a short shaft 76. Free to rotate about the short shaft 76 is a gear 77 in mesh with a gear78 .keyed to the drive shaft 8. In order to transmit the movement of gear 77 to the shaft 76, a clutch .79 is provided which is splined to the shaft 76 and adapted to be moved into and out of clutching engagement with a clutch element on the gear 77. A

the lower chute I i 67 freely rotatable on the drive shaft 8, but

veyer shifting lever 80 is,adapted to move the [clutch 7 9into-and out of engagement with the gear 7 7 so that the drum. 73 maybe rotated to and 1, for removing the excavated material upwardly and rearwardly. In order to provide convenient and eflicicnt means for loading the excavated material, a loading conis provided preferably by a chute 81 pivoted at 82 to the rear end of the supporting plate 83, (see ,Fig. 1) said supporting plate being journ'aled within an,arm, or bracket 84: projecting from the pedestal 20. Uponthe rearend of the chute 81 is otatably mounted a sprocket 85, about W ich travels an endless chain or conveyer 86, which is supported-forwardly and driven by a sprocket 87 keyed to the vertical shaft 13. In order to adjust the'height of the loading chute 81, a screw support 88, which are is reciprocably mounted in a bracket arm 89 carried by the truckframe 1, is threaded at its lower e1 in a worm gear 90, said worm gear bein driven by a worn 91when it, is in clutch with a clutch 92 splined to the shaft 8. A shifting; lever 93 serves to move'theclutch 92 into and out of clutching engagement with the worm 91 so as to raise:

and lower the chute 81 at will. Y

1, 3 and 5, the chute ,As. shown in Figs.

lates 81 are connected to the rear frame 118v at 116, 117 by means of the laterally extending bracket strips 114,115 and 114:, 115. As shown in Figs. 1, 2, 3, 1', 5, 6 and 12, the intermediate chute plates 110, 110" held in spaced apart-position by means of theinwardly extending strips 111, 111 and 104i, 101', which are respectively fastened to. the sides of the lower conveyer frame at 112, 112 and 106, 106'. The front chute plates 101, 101" are supported by means of the inwardly extending strips 104,

107. and. 104', 107 which are respectively fastened at 106, 109 and 106', 109 to the upper sliding conveyer frame, 23. It will therefore be seen that when the conveyer frame 23 is moved back and forth the chute plates 101, 101"move with the same, while he ch te plates 110, 110. remain relatively stationary.
