Application February 1, 1945, Serial No. 575,706
This invention relates to timber setting machines.
An object of the invention is the provision of a truck for carrying timbers and for raising the timbers which are to be applied to the roof of a mine and fixed in place for supporting the roof thereof.
Another object of the invention is the provision of a machine for raising and holding timbers in place until they are securely supported by props of the usual type, said machine including a wheeled truck for carrying the timbers to the mine, with the truck'body having an elongated slot in which is substantially housed a hoisting arm with means being employed for raising the arm which is provided with a saddle for supporting a timber, said saddle having a rotatable mounting so that the timber may be placed in position as desired.
A further object of the invention is the provision of a machine including a truck having an elongated slot for housing a hoisting arm, means being provided for raising the arm until the timber located in a saddle at the free end of the 7 arm has been applied to the proper position on the inner wall of a mine or tunnel, means being. employed for retaining the timber in position until said timber has been fixed in place, said saddle being rotatably mounted on a table so that the timber may be moved through any angle in a horizontal plane, said saddle being adapted to be retained in a horizontal position at all times during the raising or lowering of the arm, the housing of the hoisting arm within the slot in the truck permitting timbers to be carried on the truck to the points where said timbers are applied to the walls of the roof of the mine or tunnel.
This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible to such changes and modifications as define no material departure from the salient features of the invention asexpressed in the appended claims.
In the drawings:
Fig. 1 is a fragmentary plan view of a truck showing an elevator for applying timbers to the roof of a mine, said elevator normally being housed in a pocket or slot in the bed of the truck.
Fig. 2 is an elongated vertical section taken 9 Claims. (01. 214-430) 2 along the line 2-2 of Fig. 1, showing the elevator in an inoperative position.
Fig. 3 is a vertical section similar to that shown in Fig. 2, showing the elevator in raised position. Fig. l is a fragmentary enlarged side view of the end of the elevator, showing a saddle for timbers mounted on the free end of the elevator.
Fig. 5 is a transverse vertical section taken along the line 5-5 of Fig. 4..
Fig. 6 is a transverse vertical section taken along the line 66 of Fig. 2.
Referring more particularly to the drawings, l0 designates the flat bed of a truck upon which timbers may be carried. The truck is of the self propelled type, although the complete truck is not shown. The rear end is supported by wheels H of well known construction. The bed lfl is provided with an elongated slot l2 extending longitudinally thereof, and this slot forms a housing for an elevator or crane generally designated by the numeral I3. The rear open end of the slot is flared as shown at M for a purpose which will be presently explained,
The innerend l2a of said way between the front and rear end of the bed 10, and is of suflicient length to fully house the elevator l3 when located in an inoperative position. Th elevator or crane is of suflicient length that logs may be raised thereby for applyingtimbersto the roof of a mine tunnel or other form of chamber. 7 7
A pair of metal U-beams l5 are disposed in parallel relation and are connected together at their tops and bottoms by metal plates l6 rigidly secured to the upper and lower faces of said beams as shown more particularly in Figs. 1 and 3. The inner ends of these beams are bent down wardly as shown at IT, and are provided with collars l8 receiving an axle l9 which has its ends mounted'in blocks or supports 20 formed on the side walls 2| of the channel or slot H2. The connected U-beams [5 are swingably mounted on the axle IS.
A plurality of rollers 25 have their ends mount ed in bearings 26 connected to the U-beams l5. The rollers have their greater diameters at their ends, and they taper from the outer end to a narrow central portion. Since these rollers extend slightly above the upper edges of the U- beams they may be employed for rolling a log longitudinally of the hoisting. arm or crane I3 on to a saddle generally designated by the nuapproved manner, although in the resent inslot terminates mid stance there is illustrated a pneumatic device for This pneumatic device includes a the purpose. cylinder 39 pivoted on axle 35 which has its end-s mounted in bearings 32 (Fig. 6) secured to the side walls 2! of the channel or longitudinal slot l2, formed in the bed ill. Arms 33 secured to the bottom of the cylinder 3E3 have a bearing 34 mounted on the axle 3.5 so that the cylinder is swingably mounted on said axle. The usual piston 35 is mounted in the cylinder 35 and is connected to a piston rod 36 which passes through a bushing 3? on the inner free end of the cylinder 30. The outer end of the piston rod 38 is provided with a fork 33a having bearings 38a mounted on a rod 38 which is carried by bearings 39 secured to the inner faces of the beams it. Thus, it will be seen that when water under pressure or air under pressure is forced into the outer or pivoted end of the cylinder against the piston 35, the rod 36 will be forced outwardly and raise the hoisting arm l3 from its position within the channel or slot 1 2 of the bed Id.
The saddle 2'! for holding timbers against the roof of a room or space such as a tunnel in a mine is rotatably mounted in a horizontal plane on the circular table 48 which is hingedly connected to the outer free end of the hoisting arm 13.
As shown more particularly in Fig. the saddle 27 has a base portion 4| which has a centrally disposed pivot pin 42 formed integrally therewith. Thi pivot pin is located within a centrally disposed passage 43 in the circular table to. A ring 44 is received by the pin 42, and a nut Q5 threaded on to the outer reduced end id of the pin 42 retains the saddle Z! in position on the table while permitting the saddle to be rotated in a horizontal plane. The reduced end 45 of the pin d2 extends to a shoulder 4'! so that the ring 44 will be engaged by the shoulder for holding the saddle on the table 49, while permitting the saddle to be revolved. The saddle is provided with a pair of longitudinally disposed side bars 48 which have depending portions 49. These depending portions are provided with passages 50 to receive pintles 5! on rollers 52. The diameters of these rollers are sufiiciently great that the upper edges of these rollers are in horizontal alinement with the member 4! of the saddle so that logs may be moved back and forth until properly centered on the saddle before the hoisting arm I3 is raised.
The table 40 is provided with a pair of depending ears 55 which have bearings 56 receiving a rod 5'! carried by the outer free ends of the beams it for pivotally mounting the table 43 and likewise the saddle 27 on the outer end of the hoisting arm.
A pair of bracket 65] also extend downwardly and rearwardly from the table 4!! and are provided with passages 6| to receive a rod 62. The outer free ends of controlling bars 63 have pivotal connections with the rod 62. A bracket 58 projects outwardly and downwardly from the members 60 and in parallel relation therewith and is provided with a passage to receive the free ends of the rod 62. Cotter pins 59 in the ends of the rod 62 maintain said rod in position. The outer ends of the bars 63 are located between the members 69 and the brackets 58.
These controlling bars extend downwardly and are provided with angularly bent ends 64 which are pivotally mounted on a rod 65 carried by bearings 66 which are secured to the side Walls 2! of the channel l2. Thus, it will be seen that when the hoisting arm 93 is raised the bars will likewise be raised, but due to the particular construction of the ends of these bars and the connections between the walls of the channel on the one end and the brackets 66 depending from the table 45 on the other end causes the saddle 2! to be maintained in a horizontal position at all times as will be presently explained.
Referring more particularly to Figs. 3, 5 and 6, it will be noted that guides iii are carried by the beams 25. Each guide is provided with a slot ll to receive one of the bars 63 for maintaining said bars in close association with the beam-3 it and in parallel relation during the raising or lowering of the hoisting arm 13. Pairs of these guides are disposed adjacent the rollers 25 which are located at the inner end of the hoisting arm and at an intermediate portion.-
A seat '35 (Figs. 2 and 3) is located at the outer end or flared portion of the channel 52 for supporting the outer free end of the hoisting al'ln S3, in its lowered position when the hoisting arm has been substantially housed within the channel E2.
The operation of our device is a follows:
The Wheeled truck having a flat part or body 55 is adapted to be supplied with a number of timbers which are to be applied to the roof of a mine tunnel and the truck is adapted to be propelled by a power plant, not shown, located at the front of the truck. This power plant also is adapted to supply fluid under pressure to the cylinder 33 at a point adjacent the outer end thereof Where it is pivoted on the rod 3i The piston 3% is located at an angle to the horizontal so that the point of connection, in this instance the rod 38, with the hoisting arm i3 is above the horizontal level of the rod 3 5. Thus, when the piston 35 is operated, it will force the arm 13 upwardly, thereby carrying a timber which is located within the saddle 2i and in balanced relation up to the roof, and this timber will be maintained in place until the workmen supply the necessary supports for the timber.
The saddle 2'! has been defined as being rotatable on the table 40 so that it is not essential to position the truck'along a line which is centrally disposed of the tunnel, because the saddle may be revolved in a horizontal plane until the timber is in a proper position to be applied.
The saddle is maintained in a horizontal position at all times since the bars 63 are so formed and positioned with respect to the hoisting arm is that the outer ends of the bars through the brackets 59 will maintain the horizontal position of the saddle during its ascent or descent.
It will be noted from Fig. 2 that the hoisting arm and its associated parts are substantially housed within the channel l2 when the hoisting arm is in its lower position so that it is possible to employ the truck for transporting logs or other material thereon. The saddle 21, however, extends above the upper surface of the bed Ill at the rear end, and therefore it will not interfere with the transportation of materials on the truck.
