Patented NOV. 18', 1919.
Application filed March 31, 1919. Serial No. 286,338.
zen of the United States of America, residing at Ironwood, in the county of Gogebic and State of Michigan, have invented certain new and useful Improvements in Pneumatic Shovels, of which the following is a specification.
The present invention relates improvements in'pneumatic shovels, des gnedespecially for excavating or shoveling rock,
stone, etc, for loading on cars, and as the implement occupies a minimum amountpf head room and comparatively small radius of rotation, it is especially .adalpted ,for shovelin and loading on mine cars the coal broken own by blastin in underground mining operations, there y permittm 1ts free use within the confines of mine rlfts or openings.
The primary object of the invention is the provision ofan implement of this type which possesses simplicity in both construction and operation and is adapted for op erations in small compass, is comparatively light in weight, and ma be mampulated with facility so that it is exible and simple under control of the 'operator.-
To this end the'invention consists in certain novel combinations and arran ements of parts involving the utilization o a, pa r of co-acting, angularly disposed motive fluid pistons and their cylinders mounted upon a rotary support, and in certain other devices in combination therewith as will be hereinafter pointed out and claimed.-
In the accompanying drawin I have illustrated one complete examp e of the physical embodiment of my invention, constructed and arran ed according thebest' mode so far devise for the practical application of the principles of the mventlon.
Figure 1 :1s a view in side elevation,
partly in section, illustrating an implement neumatic shovel constructed according or to t e invention.
Fig. 2 is an elevation taken at right angles to the view-of Fig. 1', parts also being shown in section.
Fig. 3 is a plan view, showing a part .of the rot support in section, and illustrating in otted lines the lateral swinging movement of the shovel.
, Fig. 4 is a plan view of the rotary platform showing the upright side plates of the frame in section.
Fig. 6 is a perspective view showing in detail one of the links by which the implementis anchored to the rail of the track upon which the truck is rolled.
, While I shall hereinafter refer to the implement as a pneumatic shovel, it will be understood of course that other motive fluid may be employed if found desirable, but in the present instance it is found convenient to designate the implement by the term pneumatic shovel, and it will also be apparent that other changes and alterations may be made wiihi the 1e f ""7 without departing from the spirit of my in.- vention.
In the preferred form of the invention as illustrated in the diawjngs, I have utilized an ordinary minetruck 1 of usual type and adapted to travel on the track as usual, and upon the truck is rigidly and securely fastened a circular casting or fixed base plate 2, to support the rotary portion of the implement, a central toothed gear 3 being riveted or bolted to the circular plate for engagement'by the small pinion 3 indicated -in Fig. 3. The circular base 4 of the revolving frame has bearing balls 4? between it and the base plate 2 so that the rotarypart of the implement may swing or rotate freely injthe. process ,of working or loading-10f the material to be handled.
The superstructure of the implement is supported on the two upright, stiffened frame plates 5, ;5,- spaced apart andibolted securely to the base 4 of the rotary frame,,
Bend-14 at its ends for the admission and exhaust of motive fluid. The shovel 10 hich is in the usual form of a bucket is swiveled on the .pins lland has a limited supported in the plates 5 swinging movement between the two angle plates with which the clevis 9 w ll contact to prevent excessive movement of the shovel.
At the point 16 in Fig. 1 it will be seen that the piston rod 17 .of the air cylinder 7 is pivoted to the air cylinder 6, so that in conjunction with the motor 18 which is the prime mover through the pinion 3' and the fixed gear 3 for rotating the superstructure of the implement, the cylinder 6, together with a rotary electric its piston rod and shovel, may b made to oscillate in the bear-' ing blocks 19 on the pair of diametricallg opposed trunnions 20 of the cylinder These bearing blocks are supported in the upright 'side plates of the frame, and in Fig. 2 it 'willbe apparent also that the shorter cylinder 7 is also oscillatably supported in the side plates by its blocks 19' and its trunnions 20 the former attached to the side plates 5;
Motive fluid is furnished to the implement through the air pipe 21 which is fixed and and is furnished ing connected as a supply'or feed pipe for the motor 18. The branch pipe 22 is connected to the flexible pipe or air hose 25 of the cylinder 6 which communicates at both sides of thepiston through the ports 13 and 14, while the branch pipe 23 communicates with the flexible pipe or hose 26 that com municates with the'cylinder 7 through the two end ports 27 and 28 of that cylinder.
The action of the piston in cylinder 6 is under control of the valve lever 29 of the fourway cook 30, and the action of the piston in cylinder 7 is under control of the lever 31 of the fourway cock 32, and the admission of air to the motor 18 may be controlled in an suitable manner, the controlling device being located in position accessible for and convenient to the operator or attendant who manipulates the levers 29 and 31.
In Figs. 1 and 6 means are illustrated for anchor' the implement with respect to the rail R w ich means comprise an open link 22' at each of the four corners of the truck, pivoted in the metal strap 23 and the open ends of the link, as 24' are made to clasp the rail by means of the clasp-link 25 which may be forced down on thebars of the open link to clasp the rail at its free end.
' The shovel or bucket is illustrated as equipped with a hinged bottom 23" that may be latched and unlatched in any of the usual or suitable ways, and the truck may be moved along on its rails in suitable manner, as well understood In operation air is admitted to either side of the piston 12 in its cylinder 6v through theports 13 and 14 by proper manipulation of the lever 29, and air is admitted to either with branch pipes'22, 23,; 24, the latter bethe pile of material to be moved, and then by manipulation of the lever 31 the piston rod 17 is projected so that the cylinder 6 swings on its trunnions to scoop up the material, the cylinder 7 also swinging on its trunnions to compensate for the movement of the cylinder 6, and the scooping action of the shovel on the material is accomplished by a combined manipulation of the two cylinders. When the shovel has scooped up a load it is withdrawn to the loaded position indicated in Fig. 1, and then through power from the motor 18 the superstructure of the implement is rotated on the circular base plate and its ball hearings, to position with the shovel at the rear of the implement and within easy access of the car to be loaded from the shovel. The loaded shovel is then raised to the dotted position in Fig. 1 through the action of the motive fluid admitted below the piston 17 in the cylinder 7, and while in the horizontal position indicated the piston rod 8 with the shovel may be projected over the car to be loaded,
and the hinged gate or bottom 23? of the shovel is tripped to dump "the material in the car to be loaded. The reversal of this operation just described returns the shovel to digging or excavating position again, and the implement is held stable during the working operations by the shackles or clasp links 22'.
From the above description taken in connection with the drawings itis evident that the implement may be used for loading or for excavating and loading material either underground or for surface work,'and as the whole structure is compact and contained within small compass it may readily be taken into and through any mine or tunnel openin foroperations, and there be worked with e 'ciency and economy.
