yThis invention relates to mining apparatus and comprises improvementshm wheeled trucks or trolleys for mining machines,

`In 1 the ,specificatoi'r` of the co-pendingy United States application Serial No, 723,953,

filed July 3rd, 1924, inthe name `of1Morris P. .Holmes, there is described 4,a truck Aon-v which a miningmachine of[the.swin ging jib 'type can be loaded and supported either on its top or bottom softhat it can be used for over-cutting yor under-cutting and while in eitherv pesition' the A machine `can eii'ect truck 'propulsion through the medium of a clutchwhichserves to connect the feed-chain sprocket With-the truck propulsion gear.

Thepresent invention has for its main object to provide an improvedconstructionof truck on'. which the machi'n'e ,can be loaded f ting or under-cutting.-

a'nd supported von its top, bottom lor side so that it can be used for over-cutting, undercutting -or shearing without materially increasingtheioverall height of the' mounted machine when in its shearing position, while at'the same' time enabling` the machineto effect trck'propulsion when in any of its positionsl on the truck. .4 y,

According to this invention, therefore, there is provided in a mining machine truck the combination with horizontal supports'v which support the machine in a vworking position in which 1t lies on its bottomor top lengthwise on the truck, of another horizontal' support which is at a lower level than that of the other supports' and is between them andcan support the machine when it is` hori-4 zontal but on its side. TheA track platform may be providedwith a longitudinal, channel or recessto receive and support the ma; chineon its side so that the jib can swing in a vertical plane` for shearing,` whilethe portions of the platform on 'eitherside of the channel serve toY support the machine on its top or bottom so that the jibcan swing in different horizontal planes for over-cut- Preferably the truck is provided with propeiling gear which Ais so arranged as to bedi rectly engageable With a driving member on the machine when the machine-is inany one of its aforesaid positions on the truck.` For'- a machine having a` driving member situated on its central longitudinal axis, as in the aforesaid prior application thechannel or recess may be of such a depth that the rotational axis of ythe said vdriving member 5;

will be inline with the rotational axis cfa driven member on the truck when the ma; chine is on its side in the channel for a purpose vwhich willbe described. Other.Lfeaturesof the invention will be hereinafter described and pointed out in the` claiming clauses. o Referring now to Vthe accompanying drawingswhichshow a truck fora coa-1 'cutting machine of the swinging' jib chain 6 cutter typei ,F igure v1 is a side elevation of the truclg' partly `in section, and showing in chain dotted lines, the-machine in shearing position thereont c .v 4Figure 2 vis a plan of the truck with the machine` removed forclearness, j

,Figure 3 is a sectional end yelevation on the hinein-III of Figure 1.

Eigure e is The truck comprises 5a guiding frame or platform lmounted on track wheels 2 secured toaxles 8 journalled in the usual manner inarzle boxese, and Ais adapted to run 'on therails. The platform 1 is provided with a central longitudinal y channel or Arecess 6 the bott'om7 of which provides a supporter platform at a lower level than the platform 1 to support the machine 8 on itsside,` Obviouslyths 4platform be. built upaOfA a skeleton framework with suitable-.guides on, supports to take the machine instead of the solid walled construction shown. The chan? nel is of a suitable width to take the machine on ,its side, and in the construction oftruckA illustrated, which isintended for a mini ng machine having a feed-,Operating-member k9 situated on the central longitudinal Aaxis of; the machine (for example, a machine of the type described in'British Patent No, 211,473) the,` channel is ofsuch fa ydepththat the said airis liesnin the same horizontal plane when.; themachine is on its side as when omits topf or bottom 'as clearly illust-rated in Figure This is for a purpose hereinafter more fully described.

In order that the machine may be firmly secured to the truck so that cutting may be effected while the machine is in position thereon, suitable clamping devices may be provided. As shown, for clamping the machine in its shearing position a pair of yoke clamps 1() are provided which are adapted to embrace the machine. These clamps are each provided with a clamping screw 11 adapted to be manipulated by means of a tommy bar, and are each pivotally secured at 12 within the channel 6 so that they may be folded down to lie 'below the level of the platform 1 when it is required to load the machine thereon. The clamping screws 13 are adapted to engage recesses 14, (shown in Figure 4) which are provided in a Inachine of the type hereinbefore referred to, for accommodating the securing bolts holding the sections of the machine together.

In order that the machine may be loaded to and Vunloaded from either the upper or lower platforms a detachable slide 15 is provided. This slide may be centrally dished as shown at 16 to provide a guide way for the machine when on its side. Hinge ugs 17 and 1S are provided on the upper and lower platforms respectively of the truck so that the slide can be pivotally secured to cooperate with either platform as desired. The slidemay have a rearwardly extending tongue 19 whereby it is raised when the machine is loaded and which serves to steady the lowering of the machine during unloading. This tongue is conveniently situated within the channel 6 as shown. It will be understood that the machine may haul itself up the incline and on to either platform as desired by means of its feed chain.

The truck propulsion gear may be similar to that described in the said prior application Serial No. 723.953, and comprises a horizontal shaft 20 having a clutch part 21 thereon forcooperation withanother coacting clutch part 22 on the feed operating member 9 on the machine. `The shaft 2() is connected by suitable gearing, preferably including reverse bevel gearing which may be situated in the casing 23', to the transverse shaft 24 which is geared to the shaft 25 carrying a sprocket wheel 26 which is coupled by means of the driving chain 27 to a sprocket 28 on the aXle 3 of the rear pairof track wheels 2. The drive may be transmitted also to the axle of the front pair of wheels by means of sprockets 29, 30 and the connecting chain 31. VA brake 32 is shown on the transverse shaft 24.

Referring now to Figures 5, 6 and 7 which show a modified form of clutch according to this invention, it will be seen that the clutch part 21 on the shaft 20 is slidably mounted on the splined end 33 of the said `opposite the i clutch part 21 will be forced back against shaft and a spring 34 between the casing 23 and the said clutch part tends to maintain the latter in the position shown. The face of this clutch part is provided with four recesses 35 and a conical guide hole 36 terminates in a central hole 37 to receive a guide pin 38 (Figure 6) carried on the machine and projecting from the end of the driving shaft 39 on which is mounted `the feed-operating sprocket 9 and `the second clutch part 22 mounted thereon. 'The face of this second clutch part is provided with four projections 40 which are adapted to engage the aforesaidrecesses 35 on the other clutchpart 21. It will be seen that when the machine is moved endwise during loading on the truck to engage the truck propulsion gear, the guide pin 38 will engage the parts 36 and 37 and bring the shafts 20 and 39 into line.`

corresponding recesses 35 the the action of the spring 34, and thus when the shaft 39, and with it the clutch part 22?, is rotated bythe machine motor, as soon as the clutch projections and recesses `come opposite one another the clutch part 21 will be forced out by the spring into operative engagement with the part 22. The part 21 being spring mounted as described also acts Y as a buffer for the machine. i

The rotational aXis of the feed operating member 9 being arranged as herein described in the central horizontal and also in the central vertical plane of the machine and the channel in the truck being arrangedras described, itwill be seen that after change inV position of the machine upon the truck to change the plane of cut of the swinging cutting jib` 427 the position of the aforesaid rotational axis remains the same and thus the shaft 39 on the machine can be coaxial with the shaft 2O onthe truck in whichever posi-V tion the machine may be on the truck so that the clutch parts 21 and 22 can cooperate to effect truck propulsion and can be engaged with and disengaged from each other by endwise movement of the machine relative tothe truck. Although it is preferred to` arrange the shafts to be coaxial it willbe understood that this is not an essentialfeature of a direct driving connection effectedV by endwise movement of the machine, for this may be effected by means of a sliding gear connection with the shafts out of line.

Figure 4 illustrates a truck in which the machine supporting platform is arranged to be. raised and lowered by means of jacks 43 as in the aforesaid prior application; pivoted radius rods 44 being provided on each side of the platform to guide it and to enable the drive to be transmitted from the shaft 2,0 to the track wheels by means of suitable chain gear 45.
