r18 Claims.

This. invention relates t`o timber "setting machines, and more particularly to an improved'm'achine-for setting mine timbering elements, such as horizontal cross timbers, in an underground mine or tunnel.

In underground mining or tunneling, horizontal cross 'timbers are placed against the roof as the Work advances, and the cross timbers are Aset in position by uprights or props, or by rib pinnings. Such setting ofthe cross timbers is usually effected manually.. and is an extremely hazardous, arduous and time-consuming task. Also, the timbers and props must be transported long distancesin the mine or tunnel. Machines have previously been vemployed for mechanically setting the cross timbers, but'such machines are limited in operating range, are relatively 'high and bulky, and do not havesulicienttimber and prop carrying capacity or must carry the 'timbers and props on's'eparate trailers. The'present invention contemplates improvements 4over such known machines in that extreme compactness is 'attained while' providing a relatively large timber vand prop carrying capacity Within the ,machine'itsell and also a relatively wide range of operation and in- -vcreased flexibility are obtained. By the provision of 'such a machine, the cross timbers Yare moved Vup against the mine or tunnel roof and firmly held there during setting of the timbers'thereby makingythe task of timber setting relatively easyand 'minimizing the danger.

It is accordingly an object of the present invention to provide an improved timber setting machine whereby ,the disadvantages of previous machines are substantially overcome. Another 0bject is to provide an improved timber setting machine having, within itself, a'relative'ly large timberandprop carrying capacity. Yetanother object is toprovide an improved timber settingmachine 'having a relatively wide operatingrange. A .further object is to provide an improved adjustable timber supporting structure for'receiving and supporting across timber and forelevating thetimber to bring the latter up against the roo'f and yfor :holding it there during setting thereof. A still further object is to provide al1-improved `timber setting machine having a machine body .provided with arelativelyflarge'timber andprop carrying compartment arranged in a relatively 10W positionand of substantialvvidth andheight Wherebva relatively vlarge `number of Jmine timbers and props Lean be ytransported'While smaintaining Athe-overall height of the-'machine relativelylow, thereby enabling Ithe-machine to 'operate inminesor-tunnels having-relatively-lowi head 4vlarge loadcan be carriedjbut also 'affording arelatively Wide .range of adjustment.' A further object is to provide an improved Vadjustable supporting structure mounted on .'themachine body vfor horizontal adjustment wherebytimbersmay `be supported ateither `side of the machine'body as well as crosswise'at one 'end ofthemachine body.y Still another object is to provide'improved adjustable timber guides for .guiding the timbers loading of the bo'dyecompartment and 'for `directing a timber from the-'compartment 'onto the' turntable or saddle of the adjustable'timber support.

A still further objectis'to provide an improved extensible elevating jack structure for supporting and elevating a timber, together with afloor-engaging vjack for holding the parts iirmly in position during operation'thereof. It is a `:further object to provide an improved'timber setting machine having an improvedarrangement 'and combination of parts. These and other lobjects and advantages ofthe invention will, hovvever,here

inafter more fully'appear.

In the illustrative embodiment of the invention, as shown in the drawings, the improved. timber setting machine is preferably of the rubber tired, wheel mounted type especially designed for use in setting roof timbers or cross barsiiitrackless mines or tunnels. Evidently, the machine may be mounted in other manners and used for other purposes. VThe machine comprises a low compact body l mounted on rubber tired wheels adapted to travel over the floor of a mine 'or tunnel, and the

rear wheels

2, 2 are traction wheels and are driven by suitable motors, preferably electric motors, 3, 3 through suitable transmission connections e, fi. The front wheels 5, are steering wheels and are swiveled in a conventional manner to turn horizontally and are provided with suitable iiuid operated steering gear controlled by a hand wheel 6 located in a recess providing the operators station at one side of the iront end of the machine body. A motor l, likewise preferably an electric motor, drives a pump to be later described. Extending centrally lengthwise of the machine body is a timber carrying compartment S of substantial width and height. Mounted on the machine body beneath the compartment for swinging on a vertical axis and extending outwardly beyond the rear end of the body is a horizontal support 9 carrying, at its cuter extremity, an elevating jack structure I9 which supports a horizontal timber receiving support or saddle il. rihe load carrying compartment 8 is adapted to receive a load of mine timbering elements such as cross timbers and props, and a guide roller device l2 is arranged at the front end of the compartment for facilitating loading of timbers. When the support or saddle is properly positioned, a timber may be moved lengthwise from the compartment over .a rear guide roller device l2 onto the support. The jack l may be operated slightly to raise the saddle above the top of the machine body and the timber may then be turned with the saddle into a position crosswise of the machine body at the rear or the latter. The jack i0 may then be operated to elevate the saddle to bring the timber up against the roof and to hold it there during setting -of the uprights or props, or during insertion of the rib pins. Arranged in a recess at the opposite side or the front end of the machine from the operators station is a conventional cable reel mechanism i3 for the power conductor cable through which power is conducted to the

electric motors

3, 3 and l; and this reel is driven in winding direction by a conventional hydraulic motor I3. At one side of the rear end of the machine body is an electrical control apparatus I4 for the electric motors, while at the opposite side of the real) elfld. 0f the l 3G at its rear end to the lever 2l.

body is a power saw i5, driven by a hydraulic motor l5. The' traction wheel and pump driving motors, the steering mechanism, the cable reel mechanism, electrical control apparatus and the power saw may be similar to those fully described in a copending application to C. F. Ball et al., Serial No. 746,646, filed May 8, 194'?.

' The machine body is preferably of a fabricated, welded construction and has vertical plates l1, l1 extending longitudinally of and spaced equi-distantly from the longitudinal center of the machine body, and these plates` iorm the sides of the load carrying compartment 8. The compartment bottom is formed by a bottom plate 1 8, so positioned that the compartment bottom is in a relatively low position below a horizontal plane'including the wheel axes, and the wheel axles, which are herein drop axles, extend transversely beneath this bottom plate. The horizontal swinging support t is herein preferably in theform of a bell crank with one `arm El) projecting rearwardly from the machine body and at its outer end supporting the extensible jack structure, and this arm has a forward bearing support 2i swiveled on a vertical pivot shaft 22 suitably secured to the bottom plate i3 midwal7 between the plates il, at the longitudinal vertical center of the machine. Projecting laterally from one side of the bearing sup-port 2| at substantially right angles to the arm 2S is a shorter arm 23 to which the rear end of a link 2d is pivotally connected at 25. This link extends longitudinally forwardly beneath/the compartment bottom and is pivotally connected at 25 at its front end to one end of a lever 2l, the latter in turn pivotally mounted at 23 on a bracket 29 suitably secured to the adjacent side plate il. Secured to a cross plate 3@ integral with the machine body is a bracket 3l to which is pivoted, at 32, a horizontal iuid cylinder 33, also located beneath the compartment bottom. Reciprocable in this cylinder is a piston 34 having its piston rod 35 projecting rearwardly through the packed rear cylinder head and pivotally connected at Thus, when the piston is moved in the fluid cylinder, the rearwardly projecting arm 2i? may be swung through the lever 2, link 2d and arm 23 horizontally from one side of the machine body to the other, and the lower rearward portions of the plates Il are cut away at 3i to permit a wide range of horizontal swing, to locate the saddle beyond the sides of the machine body. The machine body has a horizontal rearward projection 38 l having .a rearward arcuate end 39, and the arm 23 has a vertical portion c@ which supports upper and lower projections Il! and 42, which respectively overlie and underlie the curved end 39 of projection 3.8 for guiding the arm during horizontal swinging thereof and to provide a rearward arm support. The timber elevating jack lil, carried at the outer extremity o the horizontal arm 253, may assume various forms and herein comprises a vertical uid cylinder i5 having a flange 46 secured, as by screws, to the upper surface of the vertical outer portion d@ of the horizontal arm Eil; and the lower portion of this cylinder is arranged in a vertical opening il in the vertical arm portion li, as shown in Fig. 4. Contained in the vertical cylinder is a series of cylinder and piston sections e8, i9 and 5B, herein arranged in telescopic relation and each having a piston portion and a tubular piston rod portion. Reciprocable in the bore 5l of the inner Section 50 is a piston E2 having a piston rod 53.

A return conduit |28, also passing through the arm 2li, connects the passage |25 with the suction conduit |l. Hand operated valves |29 and |30, herein of the end-seating type, independently control the communication of the passage |25 with the end chambers |23 and |26 respectively.

The conduits H1 and ||9 and |25 may have flexible portions (not shown) which extend outward from the arm 28 near its swivel bearing so that the arm may swing without interfering with the conduits in an obvious manner. So that fluid may flow to the lower end of the cylinder l5 beneath the pistons of the elevating jack Hl, the piston element 48 has vertical passages 31 in the piston head thereof, permitting ow from the cylinder bore at the upper side of the piston head to the cylinder bore beneath the piston head. The walls of the several piston rod elements are perforated at |32 to preclude trapping of fluid that may leak past-the several piston heads into the upper ends of the several cylinder bores. A

suitable shield or housing |33 encloses the fluid cylinder 56 and the valve device H8 and is provided with side openings to permit access to the handles of the hand valves |29 and |30. When the hand valves |29 and |36 are closed, fluid may flow, under the control of the slide valves i l l and ||2, through conduits Hl and H9, through the end chambers |23 and |25 of the valve device l I8, and thence through conduits 25 and |21 to the elevating and floor jacks. When the slide valves Hl and i|2 are returned to neutral position, the check valves |25 and i2i automatically prevent reverse fluid flow from the elevating and floor jacks, and when the valves |29 and |35 are opened, the elevating and floor jack cylinders are connected to the suction side of the pump through passage 25 and conduits |28 and ici, to thereby effect rapid retraction of the elevating and floor jacks. Thus, the valve device HS may serve to vent the jack cylinders and the valves 29 and I3@ thereof are normally closed during operation of the jacks. Extension of the jacks is controlled by the slide valves i l l and i i2 and the automatic check valves 42S and |2| serve, by precluding reverse iiow, to lccs: the jacks in extended position when the valves El and H2 are returned to neutral position. Evidently, the valve device i |23 may be constructed to vent the jack cylinders in other manners, as for example, directly baci; to the liquid reservoir.

The general mode of operation of the improved timber setting machine is as follows: The body compartment 8 is loaded with mine timbering elements, such as cross timbers and props, and the front roller guide device l2 may have its guide roller 19 positioned at the desired height to facilitate loading of the timbering elements into the compartment. When the body compartment is loaded, the swingable support S and the timber elevating and floor engaging jacks are moved to their transport position shown in Figs. 1 and 2, and the

motors

3, 3 may be operated to drive the

traction wheels

2, 2 to effect propulsion of the machine along the mine passageways or tunnel. Steering of the machine is eiected by the

steering wheels

5, 5 under the control of the hand- Wheel 5. When the machine is moving through a mine passageway or tunnel where there is no overhead trolley wire or other source of electric power, the conductor cable of the cable reeling mechanism I3 is attached to the trolley wire or other power source in the main entry, and as the machine moves inwardly toward the heading, the conductor cable-is pulled 01T of the reel with the cable under suitable tension. When the working face of the heading is reached and it is desired to set a cross timber, the timber support or saddle I is turned with the piston rod 53 about the vertical axis of the elevating jack ||l to a longitudinally extending position, as shown in Fig. 3, to receive a timber moved lengthwise from the timber compartment, and the transverse guide roller is adjusted vertically in the compartment to the desired height, thereby properly to receive the timber so that the latter may be easily moved outwardly onto the timber support Il. The timbers are usually piled up on top of one another in the compartment, and the guide roller 8B may be positioned to receive and guide a timber piled at any height. When a timber is positioned centrally on the timber support ll, the jack lil may be operated under the control of the slide valve to raise the timber support or saddle slightly above the machine body and the timber may then be turned with the saddle about the vertical axis of the elevating jack into a position crosswise of the machine body, as indicated in dotted lines in Fig. 15. With the pump driving motor l running to cause the pump lill! to supply liquid under pressure to the valve box |54, the slide valve lill may be moved to a position to supply liquid under pressure to one end or the other of the arm swing cylinder 33 to swing the arm 2&3 horizontally about its pivot to the desired position with respect to the rear end of the machine body (one lateral position of the arm being shown in Fig. 16), and the slide valve H5 may thereafter be positioned to trap the liquid in the cylinder 33, rigidly to lock the horizontal arm 25 in adjusted position. The slide valve may then be positioned to supply liquid under pressure past theA check valve |25 and the valve device i3 (it being understood that the valves |29 and i351 are at this time in closed seated position) to the cylinder 45 of the elevating jack ill to move the

jack sections

48, 59, 5E) and 53 upwardly to elevate the saddle to bring the cross timber supported thereby up against the roof (see Figs. 14 and 15), and the check valve automatically traps the liquid in the elevating jack when the slide valve i is returned to its neutral position. The slide valve |2 may then be positioned to supply liquid under pressure past the check valve l2| and the valve device I8 (with the valves |29 and |35 still closed) to the upper end of the cylinder 55 of the iioor engaging jack to lower the footpiece 'ill into firm engagement with the floor. The check valve |2| traps the liquid in the floor jack cylinder when the slide valve ||2 is returned to neutral position to lock the jack piston in position. The elevating jack holds the cross timber firmly in position up against the roof during setting of the uprights or props, or during insertion of the rib pins. The elevating jack lf3 is suficiently powerful and is so rigidly braced by the door engaging jack that a cross timber may be rmly held in place during setting thereof even when a loose roof or roof falls are present, and accidental dropping of the timber due to collapse of the elevating jack is prevented by the check valve |25 in the event the liquid supply should fail for any reason. When the valves |29 and E35 of the valve device ||8 are opened, liquid is discharged from the jacks through the passage |25 and the conduit |28 connected to the conduit Vlill leading to 9; thesuction sideioftjhe pump.; and-,dueto tbe suction created .within the elefr/ating,|-jaol, cyling dorsy the, jocks are rapidly. collapsed; Thoooriiig Hiv aids `in the retraction ofv4 the fioorjack piston, anduholds retracted thev fpotpiece..10 vWhen the supporting arm.20and theeleyating andoorlen; gaging jacks have been returned to theirgtransport-positimshownv in Figs, 1 v and; 2 the driving motors 3, 3.foi the trooiiori Wheelomoy'bo-rof versed. to propel themachine outkvy/arldly,vawr/ay` from `the Working face, and as tliemaehineinovle's' forwardly, the, hydraulic motoriY i3 drives. the cable reel I3 in the direction towind the con; ductorcable. in a Well known.:rnauri-r1e1gv As L.described inthe application abovefreferred'to,ltne power saw.
