MINING arranarus,

Application filed October 17, 1921. Serial No. 508,390.

My invention relates tomining apparatus. It has for its object to provide an im proved mining apparatus. A further object of my invention is to provide an improved mining apparatus wherein the lrerf cutting mechanism may be supported in different positions in an improved manner permitting it to operate over an increased range. Further objects of my invention are to provide improved elevation varying means for a kerf cutting mechanism and improved means whereby the latter may be adjusted vertically while still maintaining the desired driving connection between the truck propelling motor and the truck wheels. These and other advantages of my improved construction will, however, hereinafter more fully appear.

-- In the accompanying drawings I have IOWIl for purposes of illustration two em in practice.

In this illustrative construction, it will be noted that a truck body 1 is provided mounted on wheels 2 movable over a track way. this truck body carrying an adjustable frame 3 on which is carried the kerf cutting and truck driving mechanism. While the nerf cutting mechanism may assume various forms, as shown herein the same is in the form of a complete mining machine 41 of the flexibly fed type adapted when removed from the truck to operate upon the mine botton, the same having a usual cut-- ter chain carrying cutter bar 5 and a usual feed operating member 6 adapted to cooperate with. a flexible feeding member 7 in a usual manner. As shown, this mining machine is also operatively connected and adapted in a usual manner, when in a pre determined position on the truck, to drive the truck wheels 2 through mechanism including a gear 8 on the machine and a gear 9 on the truck, the latter being connected through usual mechanism with a transverse truck driving shaft 10 herein operatively connected through suitable gearing to a lowercooperating shaft 10 connected to the truck wheels through a sprocket and chain connection 11. vAttention is also directed to the fact that this mining machine is swiveled on the frame 3 on a suitable swivel 12 which is itself longitudinally movable when desired relative to the frame 3 in longitudinal guides 18 on the latter, the machine herein being removably connected by suitable bolts 14, 14; to the swivel and to parallel angle irons 15 angularly movable with the machine over a non-rotatable but longitudinally movable swivel plate 16 having iiXed thereto depending angle iron sup ported guides 17 movable in the guides 13 and cooperating therewith to prevent relative tilting. As shown, the machine is also adapted to be locked to the plate 16 in any desired angular position by suitable pins 18 received in corresponding registering perforations 19 infthe angle irons 15 and the plate 16, and the latter plate is adapted to be locked in any desired position in the longitudinal guides 13 by means of set screws 20 carried in extensions 21 on the guides 17 and engaging the sides of the frame ltn my improved construction it will be observed that a plurality of elevating jack mechanisms is provided between the frame 1 and the frame 3, two of the same herein being disposed at one side of the longitudinal center line of the truck while the other is disposed on the other side of the longitudis nal center line and at a point longitudinally between the first two in such a manner as to produce a three point suspension capable of riedby the frame 1 and pivoted therein on a transverse pivot 29, suitable freedom of movement of the casing about its pivot being provided by cut away portions 30. Herein movement of the member relative to the members 26 and 27 and simultaneous move ment of the member 26 relative to the member 27 is thus obtained. The pitch of the threads is also preferably so varied that the member 22 moves twice as fast as the member 26. Herein, a ratchet mechanism is utilized to actuate the jack mechanism, this ratchet including a usual ratchet 31 on the upper end of the member 26 operable by a ratchet lever 32 movable about the of the ack, a handle 33 pivotally connected to the lever 32 and normally occupying the dependentfull line position shown, also being provided to facilitate movement. As a result of this mechanism, it will be ol served that an operator by manually actuating the ratchet mechanism may cause the frame 8 to be raisedvertically relative to the frame 1, or, through different adijustments of the jacks, to be tilted laterally, as, for instance, illustrated in 4, in order to vary the level and angle of the cutting mechanism or the frame 3 as desired.

' Cooperating with this mechanisn'i is im proved mechanism acting to maintain the frame 3 in a predetermined relation to the frame 1 during the movement of the former frame and improved mechanism for maintaining the truck driving shaft 10 in driving relation with respect to the truck wheels in the adjustedpositions of the frame 8. Referring to Figs. Sand 4, it will be noted that a link connection is provided between the fram'esl and 3, which while it may be rigid laterally is herein as preferably also flexible laterally to permittilting of the frame 3. As shown, a bracing member herein of substantially ll-shape, is pivoted at its wide end at 35 to t/he front axle 36 at points be neath the frame 1, and a corresponding member 37 is similarly pivoted at 38 to a rearwardly disposed transverse stud 3!) rigidly mounted on the frame 3, herein slightly in front of therear axle, the two members being preferably disposed apex to apex, as it were, as illustrated in l and operatively connected to permit tilting. As shown in detail in Fig. 3, the ape): of each i-shaped member is connected to its fellow by a swivel pin or bolt 40 permitting relative lateral movement or tilting, and each of the memhers is provided with a surface ll forming abutting bearing surfaces surrounding the bolt l0. By this construction it will be observed that as the. jack mechanisms are operated, the frame 3 is caused to, move upward in a predetermined relationship with respect to the front axle, and that at the same time, through the pivotal connections between the two V-shapcd members, lateral adjustments of the frame 3 are permitted. Further, at tention is directed to the fact that by making the connection bet weentlie front axle andthe stud 89 of the same length as the distance b-etweenthe rear axle and the truck driving shaft 10 asillustrated, it is possible to maintain the truck driving shaft in operative relation to the truck wheels in any vertically adjust-ed position of the fame 3, connection ll. also enabling this connection to be maintained during a limited tilting movement.

Obviously the mechanism hereinabove do:

the flexible scribed may be embodied in various different forms of trucks. Herein, however, it will be noted that the same is included in a truck in which the front end of the frame 3 terminates adjacent the front end of the truck 1 mm in which the mining machine swivel has a relatively short longitudinal. t between laterally extending fiexrmovemen ble' feeding member connecting members 42 disposed parallel to one another on opposite ends of the truck and preferably having openings 43 in their extremities adapted to receive a suitable feed member abutment 44, the location of the latter and the arrangement of tne flexible feed membervarying in accordance with the type of cut desired and the location of the cutter bar relative to the truck. Attention should also be directed to the fact that suitable supplemental supporting means in the form of extensible jacks 45 are connected to the front end of the frame 8. on intersecting pivots 46 and r; that irrespective of the height of that frame or the position of the mining machine thereon, the front end thereof may be r when necessary. Fsit she ld alsobe observed that a acl: support is at rolled to the front end of the frame Qand'extonded forward therefroi i at a point between the jacks so that the latter when not in use ma? 3e swung into a transverse transport 1 thereon. i

in the operation of my in'iproved con.- strnction, a mining machine when disposed longitudinally with respectto the truck as illustratec in l is transported into a room or entry under its own power. Its adj stment in the entry or. room will of course vary with the location of the'work, butohvionsly any vertical adjustment with? in the limits of the telescopic jacks may be obtained by operation of the same or a l idly supported certain tilting adjustment may be obtained depending upon which jacks are operated. The adjustment of the bar will also vary with the type of cut required. For instance, in cutting as a continuous sweep cutter as illustrated in Fig. 6, the machine is swung on its swivel away from its truck driving mechanism and around to a position substantially at right angles to the trackway, for instance by connecting its-feeding member to one end of the rear member 42 as illustrated, the machine through control of the feed operating member by the usual control mechanism on the machine, thereafter being caused to swing in the are illustrated. In operating to cut a parallel ribbed front cut, the machine may be similarly adjusted to the position illustrated in. fulllines in Fig. 7. and thereafter, by connection of the flexible feeding member to the face as illustrated, be caused to move longitudinally to make a starting out, and thereafter connected in the most convenient manner to the members 42 to make the swinging cut, the withdrawal cut being obtained if desired by a connection of the flexible feeding member to the track at a point in back of the machine. In operating in accordance with the longwall system, the machine maybe swung into the face by connecting its flexible feeding member to a member 42 and when in the position illustrated in Fig. "8 be moved longitudinally with the truck or longitudinally relative to the truck as desired by suitably connecting the flexible feeding member to a point in advance of the machine and locking the sliding swivel against longitudinal movement on the truck, or connecting the flexible feedingmember to one of the members 42 andunlocking the swivel. I As a result of my improved construction it will be observed that'it is possible for the machine to cut over a wide range of vertical adjustment and to be tilted in each position of vertical adjustment if desired, the vertical adjustment being obtained by a compact and simple jack mechanism readily operable by an operator either to raisethe device bodily vertically or to tilt the same through different adjustment of different jacks. It will also be evident that with the machine thus adjusted, the truck may be propelled from place to place in the mine as desired without any necessity for lowering the same prior to each transport operation, a feature of dis tinct advantage where the machine is utilized in cutting in different places at the same height above the bottom. It should also be noted that not only may the mechanism be used as a support for a cutting mechanism cutting on the truck but that the cutting mechanism may be bodily removed from the truck if desired so that, for instance, the mining machine shown herein may operate independently on the mine bottom, this being possible by simply omitting or removing the bolts 14, 14;, the machine then being movable relative to its flexible feeding mem her and over and off of the truck frame 3 on to a bench when the frame 3 is adjusted to the proper elevation relative to the bench and the flexible feeding member is connected to a point in advance of the machine.

In Figs. 9 andlO, it will be noted that I have illustrated a modified form of my construction especially adapted to bench work, the same comprising a mechanism in which the sliding swivel heretofore described is omitted and a machine guiding frame 4-9 having an open front end is swiveled on a vertical axis at 50 and on a transverse axis 51 on the fame 3. Obviously with such a construction, the machine may be moved freely longitudinally relative to the truck and frame 4-9 in any vertical position of the latter without the necessity for disconnecting the mechanism and, through different angular adjustments of the frame 49, may also be delivered on a bench in advance of or at either side of the machine as desired and even on a slightly lower bench or on the bottom if desired, thereby expeditingthe unloading of the machine and at the same time increasing the possible delivery range of the machine. i

While I have in this application specifically described two embodiments which my invention may assume in practice, it will be understood that these forms of the same are shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
