Fig. l.; Fig. 5 is an elevational viewlllustratingthe manner in which thejcoal vis removed from the scoop; Fig. '6 is a plan view of Fig, 5'; Fig. 7

` is a sectional elevational view of a modifica, tion in which the scoop isin'tegralv with one' of the rack bars ateach sideof'vthe machine; f and Fig. 8 `is an enlarged fragmentary view showing aefxedl stop for .limiting the for-j ward movement of the V'apron which efect's the removal ofthe coal from the scoop. i

Referring to Figs. 1, 2, and 3, it will be seen that lthemain:frame9 is'mounted on wheels l0 to forma truck for supporting the shoveling mechanism. An electric Amotor 11 is connectedby its shaft 12, 4worm 13 and worm gear 14 to ashort transverse shaftl which is mounted in suitable bearings 16.

Mounted loosely on the shaft 15 are the bevel gear wheels 17 ,andv 18 v:each vmeshing lwith the bevel .gear 19 mounted .at thelower end of the fdiagonal shaft 2O which -is in turn mounted in 4thebearing ,21 atfthe upper Vend of the standafrd22 as shown li-n Fig. 4. `By means of frictioili clutches 23 and 24 the ,gears 17 and-18 mayioe operatively Vconnected to the ,gear 19. vThe clutches23,jand V24 are connected by the crosspiece 25 so that when l n forced longitudinally*therethrough.

The means yfor scooping up the `coal coin-I yprises a scoop 41 whichy is provided with 28, the `clutch. 23 may be engaged or disen ,and the shaft 20 connectedthereto;

gagedf-with the .gear y17 and theclutch 24 may be engaged or disengaged with the bevel gear 18. By means lof this mechanism the v'electric motorfm-ay be permittedto be rotated constantly in the same. direction ,while reverse rotation may be given to the gearv19 However-,it should be understood kthat the electricmotor 11y may be provided with any suitablheandf wellknow-n electric reversing switch and controlling mechanism. f The upper end of the inclined shaft 20 is lprovided,with `another 'bevel gear'29 which 1 meshes with the gear `30 as shown in Figs. 2 and rl`he. gear 30 is keyed to the transverse shaft 31. This shaft 31 entends en` tirelyacross the ina-chine and lis mounted ythe hearings 32, 32 as-shown in Fig. 2. At

vrigidly to the main frame 9. 'The 'bearings 32,' y32gare mounted at the Fup-per ends of the standards'36, 36 which are also rigidly connected to the main frame 9. y 1

Pivoted ltothe mainframe 9 `as shown at 37y in Fig.y 1 is a supplemental frame 38 adapted'to swing laterally to either side of its central position. I prefer to vprovide anti-'friction rollers 39,139 between the supplemental fra-me and the upper portion of the mai-n frame, although a sliding connection may be provided` if desired. Further` more, vaftrack 40, arc-shaped as shown in 3, may he provided particularly when therollers 39, 39 are omitted, so that friction may 'be reduced. f

' -'The supplemental .framel 38 is U-shaped in -cross section and open at both its' forward andits, rearward'ends so as to fornil .a flat bottom trough .or chute with vertical side wallsv'so that the coal may be brought to the forward end of the supplementalframe and then loaded into mine cars out of the rear end ofjthe supplemental frame after being vertical sides andv with flat bottom and is mental frame.

open at its rear end. lThis scoop fits into 'the forward end of the supplemental frame as shown in Fig. 1 and its lip 42 rests on the platform 43 which is detachably connected at 44 to the main frame 9.' If the platform 43 is omitted the downward movev Fig. 3. l On one ofthe pintles 46 is mounted a worm gear 48 which meshes with the worm 49..` The worm 49 iscarried on a vertical shaft to theupp'er end of which is connected the bevel gear v50 and to the lower endA of i which is connected the bevel gear 51. Meshing with the gears'50 and 51 is a bevel gear 52 carried at'the forward end of a shaft 53 whichis square in cross section and slidable in the hollow shaft 54. The sliding rod or shaft 58 ts into a corresponding recess or bore inthe rear end yof the hollow shaft 54. The shaft 53 fits into a similar recess or bore in the forward end of the hollow shaft 54. The hollow shaft 54 is mounted' in suitable bearings 55, 56 and 57 ,-so that when the electric motor -11 is operated, motion will be transmitted through the shaft l2, gears 63, 62, ieXible connections 61, 60, 59 and rod 58 to said hollow shaft 54. Rotary motion of the hollow shaft54 will thus be transmitted to the sliding shaft 53, thereby rotating the gear 52 and the gears 50 and 51. *Thef gears f 50 and'51 being mounted loosely on the vertical shaft to which the work 49 is keyed, motion to the latter is not transmitted until either the friction clutch 64 or 65 is op-v erated. A yoke 66 is fulcrumed'at 67` and connected, to the operating lever 68 so that when the latter is moved down the clutch lwill be engaged and when the lever 68 is moved up the clutch 64 will be engaged. By

this arrangement the scoop41 may be posi-` tively lifted' or lowered whenever desired. 1f the platform 43 is omitted and the lip 42 of the scoop 41 is moved over rough ground the lifting clutch may be operated whenever desired to lift the forward end of the scoop while moving forward; or, if desired, the lifting clutch maybe operated with such pressure that slipping will be permitted at the clutch while the lip ofthe scoop is held ofiI the ground at any desired elevatlon while the scoop is being moved forward.

.I will now describe the arrangement for effecting the loading of the coal or other maj terial from the shovel to the mine car. It

will be observed. that the chute or way is notarranged upon anincline but the shovel 41 is arranged to slid'e longitudinally with respect to the chute which is formed by the bottom and vertical sides `of the supplemental framel 38. Suitably mounted in the supplemental frame are rack bars 69, 69

outer end of one of thev rack bars 69 as shown in Figs. land 2. The worm wheel 71 meshes with the worm 73 which is keyedtoa vertical-shaft onwhich are journaled the bevel gears 74 and 75 which mesh with the bevel gear/76.y 4 The latteris connected to the outer end of the squared shaft l77 which slides in the outer end ofthe hollow shaft78.y The latter isr mounted in the bearings 79,80, and' 81, on the supplemental frame. Extending into the rear endof the hollow shaft 78 is another squared yshaft 82 which is connected by the universal joints 83 and 84 and a connectingrod `85 to the gear wheel 86 which is journaled on a bearing carried by the standard 87 mounted on the main frame 9. The gear 86 meshes with thev gear 62 which in turn meshes with the gearv 63 on the Vmotor shaft 12.'` It is therefore evident that whenever the'electric motorll is operatedmotion will be transmitted through the shaft 12, gears 63, 62, 86, flexible connections 83, 84, and85 to the s uare rod 82 and thence to the hollow shaft 8 and the squared shaft 77. When the shaft 77 -is rotated the gear wheel 76 will transmit motion to the gears 74 and 75, but since the latter are loosely mounted on va vertical shaft carrying the worm 73 no motion is transmitted to thelatter until either the clutch 88 or 89 is operated. A yoke 90 is fulcrumed at 91 and connected to an operating lever 92. `When the lever 92 is v lifted the clutch 88 is operated and when the lever 92 is pushed down the clutch 89 is operated. It will therefore be evident that the ejector 70 may be swung to the vertical position shown in full lines or to its upper horizontal position shown in dotted' lines.

I will now` describe the mechanism for re-A ciprocating thescoop andat the same time reciprocating the ejector. Connected tothe 101 is a bell 'crank lever fulcrumed `at v103 to `the supplemental frame.

By actuating the long 'arm 104 of ithis oper-ating lever either the clutch 99 E'or 100* mayy be operated to transmit lmotion to either the Igear 97 or .the

\ l gear 9.8, both of which are in mesh with the bevel lgear 105. The .gear 105 is keyedV to'a transverse yshaft106 extending entirely across the supplemental frame as shown inFig. 3. This `cross shaft r106 carries spur gears 107,

` 107 near the 'outside lateral facesof lthe verof the ejector 70 in one direction, and when the lever 104 is moved in the other direction motion will be transmitted to the gears 97, 105, 107, and 108 and the rackl bar 69 to move the ejector in the opposite' direction. The bodily forward and rearward movement, or reciprocating movements, of the ejector 70 are therefore fully under the control of the operator who actuates the lever 104. f

At the saine time vthat the ejector 70 is moved bodily in either direction the scoop 41 is moved in the opposite direction.. The lateral gears 107 107 are also in mesh with the teeth 109 -of the rack bars 110, 110 which are suitably mounted below the rack bars 69,69 on the supplemental frame. The rack bars 69 are `mounted in suitable guideways 111, 111 and the rack bars 110 are mounted in similar guideways 112, 112. The same lever 104 which is used for controlling the reciprocating movements of the ejector, is also used for controlling the reciprocating movementsof the scoop 41 because whenever lthe cross shaft 106 together with the gears; 107L thereon are operated the rack bars 69 yand 11.0 aremoved longitudinally in opposite directions. lWhen the scoop 41 is moved forward the ejector 70 is moved backward and when the scoop is moved backward the ejector is moved forward. When the scoop 41 is moved forward for the purpose of taking a load of-coal or other material, the ejector70 may be moved to its dotted line position shown in Fig. 1 'so that when the scoop returns with-` the load the ejector will not interfere with the' material in the scoop. By referring to the diagrammatic illustration shown in `lFig. 5 it will be seen that when the. shovel 41v has been advanced to scoop up afload of coal `from the platform or from the ground, and has been retracted to the position shown in full lines, the, ej ector should be swung out of the way as the load of material moves backwardly. rPhe ejector 70 should then be lowered to the position shown in full lines vand the rack gear operated so as to move the scoo forward at ,the lsame time that the ejector 4` 0 is moved backward. It will therefore be `understood that simultaneously with the movement `of the rack bars 110, 110 forwardly the rack bars 69, 69 are moved in the opposite direcf tion. The apron 70 as shown in F ig.r 5 not only `prevents the coal from being'advanced with the shovel by acting as a stop `or scraper,

As before statedany suitable or convenient l arrangement of gearing for positively swinging the lejector at will may be provided.

. When'the scoop is being moved forward and the ejector is 'beingmoved bodily toward 'the rear, the latter may be rotated at the same time through a small are of a circle. vIt should be observed that the ejector may be swung from its dotted line position 113 in Fig. 5 to its full line position 7 0 without at the same time operating lthe rack mechanism; therefore the material in the forward portion of the scoopv maybe pushed back effecting a partial unloading of the scoop into the chute before the scoop is moved forwardly again. Continued rotation backward of the ejector after reaching .its vertical position will effect a complete yunloading of the scoop while the latter is being moved forward.

When worm gearing is used in connection with the ejector 7 0 as shown in Fig. 1, the clutches 88 and 89 may both be released when the apron reaches its vertical position. The worm gearing will then act as ya lock to prevent the forwardrrotation of the ejector when it engages the coal on the scoop;

In'this manner the ejector may first be moved to the dotted line position 115v shown in Fig. 1 and then the scoop moved forwardly to take a load. After the scoop has been retracted to its initial position the rack mechanism may be stopped by placing the lever 104 in central position. Thenby operating the lever 92' the ejector 70 may be swung down to its vertical position shown in full lines in 1, and left in such position, the worm gearing 71 and 74 actingas a lock to prevent further swinging of the ejector. l\Tow,when` the scoop moves forward the `ejector 70 will be moved bodily backward and will not only act as a stop on to the ground if the platform is omitted.

For this purpose the .chute may be made longer by extending the same farther forward. After the materialis unloaded from the scoop and while the scoop continues forward to take another load, the ejector 70 is again swung'to its dotted line'position 115 as shownin Fig. 1, to permit the retraction of the scoop to its 'unloading position. It should also be understood, that when the scoop contains a` load in its initial position and is then moved forwardly, the ejector 70 not only positively moves the material off the scoop into the chute of the supplemental frame, but also positively moves all the material in the chute backwardly, some of -it being moved at each operation into the mine car 114,

The scoop-.41 may be adjusted in elevation by means of the worm gearing and after being so adjusted will be locked in adjusting position by reason of the worm gearing. It is therefore evident that if the platform 43 were omittedfthe lip 42 of the scoop would nevertheless be held olf the floor any desired distance. Any resistance which the oor might offer against the forward movement of the scoop would thereby be obviated. If no mechanism is provided for tilting the scoop or moving it to various adjusted positions, it may be connected rigidly to the rack bars 110, 110 so as to be held ofl" the floor any desired distance, as shown in Fig. 5.

In Fig. 7 I have shown a modification in that the supplemental frame 38 is permitted by its pivotal connection 37 with the main frame 9 to be tilted 'so that its lforward end 45 rests on the floor. The scoop 41 is arranged totelescope into the chute of the supplemental frame and the sides of the scoop form the rack bars, the upper edges of which are provided with rack teeth 109".y The lip 42 rests directly on the floor' but since the sides of the scoop may be guided in the chute so as to have no relative vertical movement thereto, the coal may be picked up from the smooth surface vwithout difficulty.

In Figs. 7 and `8 I have also shown ag' vented from moving forwardbeyond its vertical position as shown in full lines in Fig.

in Fig. 7. Therefore, when the scoop moves forwardly to take a load and then moves rearwardly with the load the ejector will be moved upwardly by the material and then fall in front of the same back ,to its full line position or nearly so. Then when the scoop is moved forwardlyagainthe stops 115 effectively prevent forward swinging movement of the ejector Inasmuch as the rack bar 69 moves backwardly at the same time that the scoop moves forwardly, the ejector 70 moves the material positively back toward the vrear end of the chute and thence into a mine car as shown in Fig. 5.

In order to increase the capacity of the .scoop the supplemental frame is pivoted at 37 to the main frame and means provided for ,moving the supplemental frame laterally on the main frame. An arcuate rack 117 is mounted on the main frame as shown in Figs. 3 and 4. Meshing with the arcuate rack 117 is a pinion 118 at the lower end of a verticalshaft journaled in the bearing 119 alt one side of the supplemental frame. lAt the upper end of this shafty is mounted a bevel gear 120 which meshes with the bevel gears 121 and 122. The bevel gears 121 and 122 are mounted loosely on a shaft carried by the supplemental frame, and associated with these gears are friction clutches 123 and 124 connected by the crosspiece 125 and arranged to be operated by the lever 126 which is pivoted at 127 to the supplemental frame and connected by the link 128 to the crosspiece 125. The link 128 may be additionally supported by the pin and slot connection 129 if desired. When the lever 126 is moved down the clutch 124 will be operatedl and when the lever 126 is moved up the clutch 123 will be operated. The shaft which carries the gears 121 and 122 has keyed to it a spur gear 130 which meshes with the gear 131 connected to the hollow shaft l54 as shown in Fig. A4. Therefore, when the hollow shaft 54 is rotated motion is transmitted through the gears 131 and 13() to the members of the clutches 123 and 124 which are splined to the shaft which loosely carries the gears 121 and 122. It is therefore evident that whenever the clutch 123 or in one direction or the other to the pinion 11S thereby effecting the movement of the supplemental frame on the main frame about its pivotal -connection'37. Although the spur gears 63, 62 and 86 are mounted on the main frame, lateral movement of the ysupplemental frame to either side from cenmodification of the ejector mechanism. By'tral position will not interfere with the p means of the stop 116 the ejector 7 0 is pre- Jtransmission of power to the scoop and 124 is operated motion will be transmitted v 35 delivery end of the chute so. that the lmateapronk because; of the fiexible connections Shown at 83, 84, 85 and at 5.9, 60, (il.

The present application is .a continuation of my co-pending application, Serial No. 611,603 filed Nov. 10, 1896, so. far as common subject-matter is concerned. l

It should also be noted that the bottom of the scoop 41 constitutes a forwardly extending 'platform with an inclination which is adapted to enter a horizontal kerf in a mine wall and dislodge a block of material which has been cut with kerfs above and below and on both sides thereof; this is particularly true if the platform 43.. is omitted. While the apron. mechanism is, preferred, the material may be delivered to the chute without the use of theapron "(0.l If the. latter is omitted, or if it. becomes broken, loading operations may nevertheless be carried on. Iny suchv event the load may .be gathered by the scoop and then retracted while. thev forward end thereof is lifted to a higher .elevation so that the material will slide out of the scoop into the forward end of the horizontal chute and then 'be transferred infany desired manner tothemine car in the positiony illustrated in Fig. 5,. rThe scoop 4:1 may be .tilted while in its initial position or while in any of its forwardpositions, and may therefore be adjustedsothat its bottom will act as an inclined plane for material to. slide from themine wall into'the .forward open end of the staticmary` chute. It should also be observed that the scoop is pivoted approximately in vertical alinement, with the rear rialmay be gathered and delivered tothe horizontal chutey in a very low-roofed mine without the use of theapron, whenever desired. It willalSO be noted that the scoop is pivoted on a transverse horizontal axis above the plane of the axis of the propelling wheels l0. vThe transverse horizontal axis of the propelling wheels .isapproximately in a plane above the bottom 3.8 ofthe longitudinal chute, the forward end of which re.- ceives thev rear end of the scoop, and the rear end, of which extends into a mine car, as

shown in F ig. 5. yThe material to. be loaded is therefore transferred along the chute back of the scoop between the wheels, and therefore along a pathv very near the floor of the mine chamber, asshown in Fig, 1. l i.

Obviously those skilled in they art may make various changes in the arrangement Y and details of., the parts without departing from the spirit and. scope of my invention as defined by the claims, and I desire therefore not to be restricted tothe precise construction herein disclosed.`
