In the illustrated embodiment of the invention, as shown in the drawings, the improved adjustable supporting structure for the timber receiving support or saddle is, for illustrative purposes, shown embodied in a timber setting machine of the same general type as that disclosed in an application t L. G. Felderman and A. S. Knoizen, Serial No. 746,832, filed May 8, 1947, although it will be evident that the invention may be embodied in machines of other types.

The timber setting machine as shown herein comprises a portable body I mounted on rubber

tired wheels

2, 2 and 3, 3 adapted to travel over the floor of a trackless mine or tunnel. The

wheels

3, 3 are traction Wheels and are driven by motors 4, 4 respectively. individual thereto, through suitable transmission connections 5, 5. The wheels 2, 2 are steering wheels, and are suit ably swiveled and provided with suitable steering gear controlled by a hand wheel 6 located at the operators station at one side of the machine. A motor 1 drives a pump 8 to be later referred to. Extending longitudinally centrally of the machine .body between the wheels is a load carrying compartment 9 which is adapted to carry a load of mine timbering elements, such as cross timbers and props. Arranged at one end of the machine body is a timber receiving support or saddle l0, positionable to receive a timber moved lengthwise from the body compartment 9. The improved adjustable supporting structure I includes a horizontally swingable arm or boom ll, herein arranged on the machine body beneath the load carrying compartment 9 and projecting outwardly beyond one end of the machine body and which carries, at its outer end, a vertical elevating jack l2 and a floor engaging jack [3. The timber receiving support or saddle I is carried by the elevating jack l2. When a mine timber is placed on the saddle I0, with the latter positioned as shown in Figs. 3 and 4, the jack I2 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 one end of the latter. The jack l2 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.

Now referring more specifically to the improved adjustable supporting structure, it will be noted that the swingable arm or boom H has an inner bearing portion l5 pivotally mounted on a vertical pivot pin I6 suitably secured to the machine body beneath the load carrying compartment, with the pivotal axis located midway between the sides of the machine. The arm or boom structure has a horizontal arm portion l1 projecting horizontally outwardly beyond one end of the machine body; and this arm portion is extensible and comprises an inner arm part l8 and an outer arm part 19 telescopically arranged at 29 within the inner arm part and guided for axial sliding adjustment so that the outer arm part maybe slid rectilinearly relative to the inner arm part. The arm bearing portion 15 is preferably formed integral with the inner arm part l8, and the latter part has an integral right angle arm portion 21 pivotally connected at 22 to one end of a horizontal link 23, herein extending longitudinally of the machine body beneath the load carrying compartment, as shown in Figs.

4 3 and '7. This link is pivotally connected at its opposite end at 24 to a horizontal lever 25, the latter in turn pivotally mounted at 25 at one side of the machine body. Pivotally mounted at 21 on a cross plate 23 integral with the machine body is a horizontally swingable fluid cylinder 29 containing a reciprocable piston 30 having its piston rod 3| pivotally connected at 32 to the lever 25. Thus, when the piston 39 is moved under the influence of fluid pressure in the cylinder 29, the outwardly projecting arm H may be swung about its pivot through the lever 25, link 23 and arm portion 2| horizontally across one end of the machine body from one side of the machine body to the other. The machine body has a horizontal end-projection 33 provided with an arcuate end 34, and the inner arm part l8 has integral upper and

lower projections

35 and 36 which respectively overlie and underlie the curved end 34 of the body projection 33 for guiding the arm during horizontal swinging thereof and to provide an outer arm support. Arranged longitudinally within the arm near the bearing portion I5 is a horizontal fluid cylinder 31 extending longitudinally of the arm portion IT as clearly shown in 'Fig. 6. The cylinder 31 is secured at 38 to the inner arm part 3 and contains a reciprocable piston 39 having its piston rod 49 extending outwardly through one end of the cylinder and secured at M at its outer end to the outer arm part l9. Thus, when the piston 39 is moved under the influence of pressure fluid in the cylinder 31, the outer arm part 19 may be moved axially relative to the inner arm part to increase or decrease the length of the arm portion H as desired. When fluid is trapped in the cylinder 31, the outer arm part 19 is rigidly locked in axially adjusted position.

The timber elevating jack l2 may assume various forms and is herein similar to that disclosed in the application above referred to, and comprises a vertical fluid cylinder 43 rigidly secured to an outer frame portion integral with the outerend of the arm part l9 of the arm II, as shown in Fig. 5. Contained in the vertical cylinder 43. is a series of piston and

cylinder sections

45, 46 and 41, herein arranged in telescopic relation and each having a tubular piston rod portion. Reciprocable in the bore48 of the inner section 41 is a piston 49 having a piston rod 50. The outer cylinder 43 and the

sections

45, 46 and 41 respectively carry suitable packings 5|, 52, 53 and 54, sealingly engaging the several piston rod peripheries to prevent leakage. exhausting fluid from these several cylinders will latex-be fully explained. Secured at 55 to the upper end of the piston rod 50 of the inner piston 49 is the timber receiving support or saddle ID. This support or saddle has a timber receiving platform 56 which is resiliently and tiltably mounted on a lower support 51 so that the saddle may have limited endwise tilt relative to the jack to compensate for the unevenness of a roof against which a cross timber is to be placed. The timberreceiving support or'saddle i0 may be turned with the inner piston rod 50 about the vertical axis of the'elevating jack l2 to locate the saddle in its various positions. The floor engaging jack [3 includes a vertical fluid cylinder 58, carried by the arm-frame portion 44 near the elevating jackand containing a reciprocable piston 59 having its piston rod 60 extending downwardly through the lower cylinder head and carrying a footpie'ce 6|. The piston 59 may be The means for supplying fluid to and moved downwardly-under-theinfluenceof pros surefluid in the cylinder 59 to move the-foot piece 61- into -firm engagementwith r the floor, thereby *to' provide astable bottomsupport-for theelevating-jack during the timber setting op oration; Since the specific" structures of these jacks arefully described in the application above referre'dto-and donot p'er-se' enter into the present" invention, further description thereof hereinis unnecessary other than tostate that pressure fluid may be admitted to the jacks-to-elevate-the s'addleifl' and to bring the floorjack t3 down against the floor. As" above --mentioned; the ole vating jack-i2 may be extendedto bring at'imberelevated by'the saddle up againstthe mine ortunnel roofand firmly to hold itthereduringsetting of the timber. When the jack cylindersare suitably connected to discharge; the jacks will;

' As has been explained; in a timber setting m'achine-ofth-echaracter disclosed, it isofttimes desirable to=ad=frust the timber receivingsupport or' saddle a i E --h'orizontal-ly through a relatively wide rangeboth longitudinally and laterally relative-to the machine body toeliminate the necessity of frequent maneuvering of the machine during proper placing of a timberwith' respect tothe roof; and, in this-improved construction, sueh positioningmay be eiiected by supplying fluid under pressure to the fluid cylinder 31 to extend or-r'etractthearm i l andbysupplying fluid under' pressure tothe'arm-swingcylinder 29 to swing-the armhorizontally about its pivot across onee'nd of themach-ine from one side of the-machinebody- ""13h6'0i3h1; By proper control-oi thearmexten-sion and swing cylinders, thearm it may be adjusted to move the jacks and the timberreceiving support ina horizontal direction both translationallylongitudinally and arcuately laterallywithrespectto the machine body, and by extendingthe' arm structure its full length, the timber receiving support maybe located at a substantial distance beyond the sides of the machine body, as indicated in dotted-lines in Fig. 1. The outermost longitudinal adjusted position of the timber receiving support is indicated in dotted lines in Fig. 2, with the improved arm structure fully extended. When the timber receiving support It) is in the full line position shown inFigs. l and 2 and a timber is suitably positioned thereon, the slide valve 15 may be operated to supply fluid under pressure to the cylinder 43 of the elevating jack l2 to move the

jack sections

45, 45, 41 and 50 upwardly to' elevate the saddle H! to bring the cross timber supported thereby up against the roof, and the extended position of the elevating jacks is indicated in dotted lines in Fig. 2. When the cross timber is suitably positioned against the roof, the hand valve 84 may be closed to trap the fluid in the elevating jack to hold the timber in firm engagement with the roof. As the timber is raised against the roof by the elevating jack, the s1ide-valve-1i may be operated to-supply fluid under pressure to the upperend of the cylinder 58 of thefloor engaging jack to lower the footpiece 6-i- 'i-'ri-to-firm" engagement with the floor, thereby to-provide a stable bottom support for the elevating-jack during setting of the timber. When the footpiece is suitably positioned in con tact-with; the floor, the hand valve 82' may be:

" closed to-:lock the floor.jackinextended position The elevating jack I2 holds the cross timber firmly up against the roof during setting of the uprights or props, or during insertion of the rib pins. It will be evident that the horizontally extensible arm II and timber elevating jack l2 may be located at any position across one end of the machine body and at either side of the machine body, and the timber receiving support may be located laterally beyond the sides of the machine body, thereby reducing the necessity of frequent maneuvering of the machine during the machine or at any desired position across one end of the machine body between the sides thereof. By arranging the extensible arm structure in the manner disclosed and by the provision of the structure for extending and retracting the same, not only is a wide range of adjustment provided but also an extremely sturdy and compact construction is attained. The machine is extremely low in height, well adapted for use in underground mines or tunnels having low headroom. Other manners of use and advantages of the improved timber setting machine will be clearly apparent to those skilled in the art.

While there is in this application specifically described one form which the invention may assume in practice, it will be understood that this form of the same is 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.
