Be it known that 1. CHARLES Howann FUNKIGY, a citizen of the United States, re siding at. Ramsay, in the county of Gogebic. State of Michigan, have invented a new and useful lVline-Car-Loading Shovel; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same. i

The invention relates to loading shovels for mine cars and has for its object to provide a shovel of this character which will be compact in form and of such a size that the same may be used in tunnels or drift headings of mines whereby the broken materials may be .shoveled rearwardly into the mine car. It being the present practice to shove! the broken material into the cars manually which requires considerable time and several men.

A further object is to provide a mine car having a longitudinal slidable cross head slidable on cross head guides carried on top of the cars, said cross head having pivotally mounted therein atransversely slidable yoke, which yoke carries an air cylinder having a shovel carrying piston mounted therein, and to provide means whereby the cross head and shovel may be simultaneously moved toward the front of the car during a shoveling operation. Also to provide means whereby the transversely slidable yoke may be moved transversely and the oylinder carrying the shovel piston tilted upwardly or downwardly at its forward end so that said shovel may be placed in engagement with the broken material on the mine floor and dragged rearwardly into the car.

A further object is to provide a tiltable hopper at the forward end of the car. up the inclined bottom of which the material will be dragged during a shoveling and loading operation, said hopper being controlled by a lever whereby it may be tilted upwardly or downwardly as desired. A further object is to provide a pivoted door at the rear end of the car through which the material may be moved from the car, after said car has been moved to any position desired.

A further object is to provide means whereby the cross head and shovel piston may be simultaneously o erated from a single source of power, anc means whereby said power may be controlled.

A further object is to so position the cyl inder on the cross head and the cylinders carried by the sides of the car which move said cross head so that when pressure is admitted to said cylinders simultaneousl'v. the speed of forward movement of the shovel will be greater than if only the shovel piston or the cross head controlling piston were singly operated.

Tith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the car and shovel carried thereby.

Fig.2 is a top plan view of the car.

F 3 is a front ele ation of the car.

Fig. 4 is a perspective view of the air pipes leading from the control valve to the air cylinders.

Fig. 5 is a detail perspective view of the door hook.

Fig. 6 is a persepctive view of the tiltable Fig. 7 is a horizontal sectional view through a convential form of four-way valve for controlling the movement of the shovel piston and the cross head pistons.

Referring to the drawings. the numeral 1 designates the body of the mine car and 2 a wheeled truck to which the body 1 is pivoted as at 3, so that the body of the car may be pivoted around in a horizontal plane when desired. The fori 'a rd end of body 1 is open as shown at 4 and the bottom of the body is provided with a. downwardly and forwardly extending inclined, portion 5*. Pivoted as at 6 to the inclined portion 7 is a hopper 8. said hopper having upwardly extending sides 9, which prevent the material as it is dragged into the car body during a shoveling operation from being forced transversely and out of registration with the front of the car body. The hopper S has pivoted to one of its sides 9 as at 10 a link 11. which link has its other end pivotally connected as at 12 to the arm 13 of an operating lever 14. )referably a foot actuated lever. Lever 14l1as sufficient flexibility s( that the lug 15 may slide over teeth 16 of a rack 17 secured to the side of the body of the car so that the hopper 8 may be maintained in any position to which it may have been moved. hopper 8 is to provide an extension to the inclinedbottom 5 of the body so that the material may be dragged up the inclines of both the body and the hopper into the main car body. An additional function of the hopper 8 is after the mine car has'been tilled the hOpperSwheri moved upwardly forms a closure [for the front opening 4 of the body.

Pivoted asat 18 to the rear ends of the sides'l9 ot the body 1 at the car is a closure 20, which closure is adapted to be swung open as shown in dotted lines in Fig. 1 when it is desired toshovel or remove the mined material from the car after the same has been transported from the niinc. Pivoted to the under face of the car body as at 21 betweenears 22 1s a weighted hook 23. the weighted end 2+1- ot which normally holds the hooked end 24-" upwardly and in engage- Secured to the upperends ot the sides V and held spaced therefrom by means of lugs body 1 and is provided with L-shaped members 32 which overlie thcupper edges of the cross hcad guide 26 thereby additionally bracing the guide bars 31 as the same are reciprocated. Pivotally secured to the ten ward ends of the guide bars 31 as at 33 are rea-rwardly extending piston rods 3%. Piston rods 34 are disgosedin air cylinders 35 and areprovided with pistons 36 which are "adapted to be reciprocated so that the cross head 27 may be moved forwardly and rearwardly during a shoveling operation. Cylnr ders are secured to the sides 19 of the body of the carby means of brackets 37. However. the cylinders 35 are of conventional form and although the same are described as aircylinders, it is to be understood that steam or fluid may be utilized for driving'the pistons 36.

Risingupwardly trom the cross head 27 The normal function of the are spaced brackets 88 in bearings 39 ot which the pintles -l-() oi the shovcl cylindcr 4L1 are pivotally mounted and also transversely Slidable." By pivotal]; and slidablv mounting the pintlcs ll). it will be seen that the shovel cylinder may be tilted vertically during a shoveling operation and also moved transversely so that shoveling ol' the matcrial from the ground may be accomplished tor the full width ot the mine car. Shovcl cylinder 4-1 l as slidably mounted in a bean ing 42 thercot' a piston rod 423. which piston rod is provided with a conventional Form of piston t-l adapted to be rcciprocalcd within the shovel cylinder it so that said piston rod 43 may be moved torwanlly and rcar- *ardly during a shoveling operation. He-

curcd to the 't' n'ward end ot the piston rod :13 as at l? is a transverse portion in of a U-shapcd mcmbcr 4-7. the arms ill of said U-shaped member being slidably mounted in guides 4' 9 carried by the shovel cylinder ii. i irms rb as the shovel 50 is forced downwardly into the broken material. localcd lorwardly oi the car and is then dragged rcarwardly so as to drag the material into the car. term means tor bracing the shovel during these operations. The lJ-shapcd mcmbcr ST is provided with brace members .71 for bracing its corners. Shovel 50 is bolted as at 52 to the portion 4-6 of the U-shapcd member 4:7 so that said shovel may be easily removed and replaced with anothcr shovel when the same becomcs worn or brokcn. Secured to the outer end ot one of the pinllcs +1.0 is an operating lever 53. which lever is adapted to be grasped by the operator when it is desired to move the shove cylinder =ll transversely and also adapted to be used by the operator for tilting the cylinder ll in a vertical plane during a shoveling operation. It is contemplated to manually control the shovel during a shoveling operation. and the parts so balanced and made oi such a size so that this will be possible. is thc car 'is'adaptcd to be used in (lril't headings and the like oi mines. it will be seen that the same will not be cxtrcn'icly largc.

Air "tor operating the pistons 36 and it is obtained from any suitable source through a flexible hose which may be connected at 5% to the pipe which pipe leads to the intake opening 56 ot a tour-way valve 5?. The air passes upwardly through the intakc opening 56 and through the port .38 so that the air will pass into the pipe 5.) 'lrom which pipe 59 it will pass to the forward end ot the cylinders 35 and 44; through the pipes (ll) and (31. Air being admitted to the forward ends of the cylinders 35 and 4-4: it will be seen that the pistons 36 and at will be torccd rearwardly. thereby moving the shovel 50 rearwardly. However. when the port 58 is placcd in registration with a pipe :39. an exhaust port 62 is placed in registration with the pipe (33.

which pipe 63 is connected withthe rear end of the cylinders anda by means of pipes 64: and 65;.thereforelas the pistons :36 and +14 and moved simultaneously rearwardly, the airirom the rear endvof the cylinders will be exhausted through the pipe 63; exhaust port 62: and outlet port 66 totheatmosphere.

Whenthe air portfi? is placed into registra:

times be completely under the coirtrolort the 1 operator through the medium of the levcr72. 4o

ift willgbeseen that as the cylinclcrvll' is carried by the crossihead 27, which cross head is moved forwardly simultaneously with the mawaat movement of the piston rod 43, that the shovel will be: rapidlykadvanced and moved rearwardly during a shoveling operation, thereby getting the maximum of reach andat the same time insition and pivoted upwardly at its forward end as shown by the dotted line C, as shown in Fig. 1, however, the upward pivoting of. the outer end is not absolutely essential.

- Then the forward end of the shovel cylinder 41 is tilted downwardly as shown in dotted lines in Fig. 1 until the shovel 50 is embedded in the material located forwardly of the hopper 8. The shovel being embedded in the material the four-way valve is then moved so that the cross head 27 will again be moved rearwardly and also the piston rod 43, so that the material liehindthe shovel will be dragged into the body 1 of the mine car. During this backward dragging of the material the shovel cylinder ll and shovel are controlled by the operator through the medium of the lever 53.

l rom thc above it will be seen that a mine car is provided with a loading mechanism,

which loading mechanism is eiitremely simple in construction and maybe easily con trolled by one man; By providing such a car it will be possible to rapidly loadthe cars and eliminate the present practice of manually shoveling the material into the cars. By so positioning the shovel and operating the same, it will be seen that the car may be \vorkedin drift headings and tunnels. i
