movement for loosening and removing the' chine having a scoop and an endless conveyor-,c means being provided for delivering material directly from the scoop onto the conveyor.
A. third obj ect of the invention is to provide a scoop mounted on a iifth wheel to enable the same to operate on material on either side of the path of the carria e Another object of t e invention is to construct a shoveling and loading machine particularly adapted for use in mine rooms and tunnels where the ceilings are low and the head room necessarily limited. Y
Y With these and many other objects in view, which will more readily become 'apparent as thenature of the invention is` better understood, the same consists in the novel construc tion, combination and arrangement of parts to be more fully described, illustrated and claimed.
In the accompanyin one sheet of drawings, formin part oit is specification, like characters o reference are emplo ed in all the separate views to designate li e characters throughout, and; l
Figure 1 is a side view partly in section of 'a machine constructed in accordance with the invention showing the same in actual use.
Figure-2 is a top plan view of the device showmg the scoop in a plurality of positions.
The device includes in its general organization a carriage or main frame 10 supported v on axles 11 carrying anged wheels 12 supported on rails 13.
' A fifthwheel 14 is mounted on the forward f end of the frame. The fifth wheel is in the open at its front to permlt filling of the scoop extending trunnions 15 to which are pivoted a pairof links 16 that 'function as booms to sup` port a scoop 17. The scoop 17 has a'pairof walls 18 and 19 which cooperate to form the heel of the scoop Vand which in the loading position of the scoop comprise the back and bottom respectively of the scoop. A pair of side walls 20 complete the structure of thescoo which `as shown is and is also open at the end opposite the botf tom 19 to ermit discharge of the contents thereof. ,n each side 20, preferably adja cent the back 18 are lateral trunnions 18 which are adapted to extend through eye holes in the ends of the links 16, and thus serve as bearingsfor the scoop. The bearings-are preferably spaced from the open end of the scoop at a distance somewhat reater than vthe length of the links so that t e dis-v charge end of the scoop may extend a'considerable distance over the forward end of the carriage when the scoop is tilted to the requisite angle for dumping. Dipper teeth 19 are located at the forward end. of the bottom wall-19 and a stop 20 may be provided on the fth wheel 14 to limit downward movement of the scoop.
The sides 20 of the scoop are provided along their forward edge at a point preferably intermediate the ends ofthe scoop with angular protuberances 21 having aligned apertures formed therein through which there extends abar'22 to which a hoisting cable 23 is attached. This cable passes over one end l80 of the scoop and a bracket 24'secured to the under side of the scoop guides the cable and prevents damage to the same. v
The main frame 10 of the carriage has a pair of standards 25 and a second pair ofstandards 26 mounted thereon. These standards support between them a cylinder casting 27 in elevatedposition longitudinally of the carriage. The castin 27 has a Vcylinder 28 therein, which is close at one end and a suit I0 c able bushing 29 is mounted in the other end of the cylinder to slidably return a plunger 30 in position. The outer end of the plunger has a yoke 31 thereon and a pulley 32 is suspended in the yoke for guiding the cable 23. A stationary bracket 34 is mounted on the cylinder casting 27 and this bracket carries a pulley 35 for guiding the cable 23. Rollers 50 and 51 are mounted in rfront of the bracket 34 for aiding in retaining the cable 23.
A pair of cylinder castings having cylinders 4Ltherein are pivoted at 43 to the carriage frame and plungers 44 having pistons 45 thereon are slidable in the cylinder. The outer ends of these plungers are connected to arms 46 on the fifthpwheel 14, and by means of this combination .of elements the scoop is caused to deviate from the axis ofcarriage. f
The cylinders 41 each have inlet ports 50 that communicate through air lines 52 and 53 to a valve 54 and this valve has an inlet 55 from the main air line 56.
The cylinder 28 has an inlet port 57 whichl port communicates through an air line 59 to a valve 6l having an inlet 62 from the main air line 56 and an'outlet port 63. A bleeder port 60 is formed in the cylinder casting 27.
An endless conveyor 70 is mounted on the carriage in aiframe 71 in the manner shown and this conveyor leads from a point rearwardly of the scoop to an elevated p'oint rearl.wardly of the carriage to enable material to be loaded on the mine car 75.
The carriage is driven through a chain and sprocket mechanism 76 operatively connected to a motor 77. Similarly the conveyor 70 ,is driven by a worm and gear mechanism 79 gperated by a motor 8O on the conveyor frame In actual operation the carriage is brought to the foot of the excavation and the valve 61 is opened to permit air in the cylinder 28 to escape through the port 63. This opera- A .tion permits the plunger 30 to be drawn into the cylinder 28 to lower the scoop to its oper- .ative position. The motor 77 is .then started to advance the carriage and directional movement of the same serves t0 load the scoop. When the scoop is fully loaded, the valve 6l is afrain operated to admit air to the working'si e of the plunger 30. As the plunger is forced outwardly of the cylinder the scoop is tilted and the material therein is deposited directly on the conveyor and carried to the mine car 75. 1
The invention having been described, it is to be understood that various modifications are contemplated without departing from the spirit of the invention and Without sacrificing any of the advantages. For example, Iconteinplate employing electrical means for operating the device instead of compressed air, if desired. Only in so far as I have particularly pointed out my invention in the appended claims do I desire to be limited.
I claim:
1.l In a shoveling and loading machine, the combination of a carriage, a fifth wheel mounted on the carriage for oscillation about a vertical axis, a conveyer, a scoop, a link pivotally connecting the scoop to the fifth wheel and adapted to translate oscillation of the fifth wheel into sidewise movement of the scoop, said scoop being adapted to deliver its contents onto the conveyer, a cylinder pivotally supported on the carriage for oscillation about a vertical axis and having a piston and piston rod, said iston rod being directly connected to the fi th wheel to effect the oscillation thereof.

4. In a shoveling and loading machine, the combination of a carriage, a conveyer, a link pivotally supported on the carriage adjacent the receiving end of the conveyer for swinging movement in a vertical plane, a scoop having a front digger element and an open end for the discharge of the contents of the scoop, xed bearings on the scoop for pivotally mounting the scoop on the end of the link, said bearings being located at the back of the scoop at a point sufficiently spaced from the discharge endvof the scoop to permit the dis- 1 charge of the contents of the scoop directly onto the conveyor as the scoop is tilted to the requisite angle, a haul e mechanism sup- .ported on thecarriage a ve the conveyor a cable attached at one end to the front o the scoop at a oint intermediate the ends of the scoop an at its other end to the haul-v age mechanism, said cable being entrained over the discharge end of the scoop during the Y loading thereof.
In testimony whereof I have signed this specification.
