T0 0. whom it may concern:

Be it known that I, WASHINGTON .FoGLE- SONG, a citizen of the United States, residing State of Ohio, have inventedcertain new and useful Improvements in Excavating and Loading Apparatusyand I'do hereby declare the following to be afull, 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. 1

My invention is an improvement in'apparatus for excavating and loading; and it consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate" one form in which I have contemplated embodying my invention, and-said invention is fully disclosed in the following description and claims. Referring to the said drawings, Figure 1 is a top plan view of my improved apparatus for excavating and loading; F ig. 2. is a side view of the same. Fig. 3 is alongitudinal sectional Fig. 4 is a transverse section on line4 4, Fig. 1. Fig: 5 is an enlarged View of one of the driving-gears of the mechanism for actuating the dumping end board, showing the clutch operatingin connection therewith. Fig. his a sectional view of the same. Fig. 7 is a longitudinal sectional view of part of the apparatus, showing the arrangement of levers for operating the clutches with; which the machine is provided.

The main frame of the machine consists of a continuous bar A of flanged iron in the are braced by suitable cross-bars o. to render the construction strong and to assist in supporting an electric motor, which is indicated at Band which is supported by two of the cross-bars a a' adjacent to the middle of the machine and provided-with a'driving-pulley b. At the front end of the main frame-is a transverse shaft 0, which is provided centrally with a driving and supporting wheel or roller 0, preferably having its outer surface corrugated or roughened. The rear end of the The-shaftE is also provided with a pinion e,

meshing with a gear-wheelfon a shaft F, mountedon the main frame forward of and parallel to shaft E. The shaft F is also provided witha pinion f meshing with a gearwhel C, loosely mounted on the shaft 0 of the'driving-wheel o and adapted to be connected to said shaft by a clutch c of any preferred style. The clutch c is thrown into and out of gear by a lever G, located on a platform H, carried by the rear end of the main 10 frame and providedwith a seat 72. for the operator, said lever being connected by a link g-with a bell-crank lever g, which is connected bya link 9 to the clutch. Any other preferred means may, however, be employed to '75 operate said clutch, if desired.

K K represent the scoop lifting and supporting arn1s,'which are provided near their rear ends withdownwardly-extending brackets 7t, pivotally mounted on a cross-shaft L, mounted in bearings on the rear part of the main frame. The front ends of the arms K K are pivoted to the upper part of the scoop or shovel M, andsaid bars are connected by suitable cross-bars, as indicated at 7t 7t and 71: In" order to maintain thescoop in a horizontal position as it is raised or lowered, I provide on each side of the machine a link or rod Npwhichis pivotally connected at one end to the scoop at '7 adjacent to the bottom 0 thereof and has its other end-pivoted to a part of the main frame, as shown at'n";

The rear cross-shaft'L is provided with a large drivingisprocket-wheel Z,which is driven by a chain 1 from a smaller sprocket-wheel 5 f on the cross-shaft F. The shaft L- is also provided with a bevel-gear Z mounted loosely on the shaft and meshing with a horizontal bevel-gear 0, carried on a verticalshaft 0,

provided with bearings 0 o, engaging the shaft L, as shown most clearly in Fig. 4. This yoke is connected by an arm 0 with the rear cross-bar of the lifting-arms, so that.

the yoke, shaft 0, and beveled pinion 0 will remain always in the same position with respect to the lifting-arms. The vertical shaft O is provided at its upper end with a crank 0 which is connected by a link 0 to a pushbar 0 mounted in guides on the cross-bars 70 7c, and the forward end of the push-bar o is connected to a dumping end board M, arranged in the scoop or shovel M, the arrangement being such that when the shaft 0 is ro 'tated a complete revolution the end board will be forced from the inner end of the scoop to the outer end, thus discharging the contents, and will then be withdrawn to the rear end of the scoop again.

I provide a clutch mechanism for giving the shaft 0 one complete revolution, which in this instance is'made as follows, reference being had to Figs. 5 and 6: P represents a clutch wheel or pulley secured rigidly to the shaft L at one side of the hub of the bevelgear I and is provided with an annular groove 17 adjacent to the pinion. The clutch-wheel P is provided with a sliding bolt 19', Working in a transverse aperture in said wheel and adapted to enter a notch or recess Z in the hub-of the bevel-wheel Z being forced thereto by a spring 19 secured to the clutch-wheel and engaging the bolt 19. The bolt 10 has the end adjacent to the bevel-wheel Z reduced on its upper side to form a shoulderp the said reduced portion being flush with the bottom of the annular groove 19. Q represents a Wedge which is secured in this instance toa springarm q, supported from a part of the framingin this instance the rear cross-bar k of the lifting-arms. This wedge lies in the groove 19 at such a point that the notch or recess Z in the hub of the bevel-gear Z will be opposite the thickest portion of said wedge when the end board is in its rear or retracted position. Q represents a lever extending within reach of the operator and provided with means for lifting said spring-arm q and wedge Q, in this instance a stud (1. By operating this lever the wedge Q will be lifted out of the groove p, and as the clutch-wheel P revolves, carrying with it the bolt p, when said bolt comes opposite the recess Z it will be forced into it by its spring 19 and the bevel wheel or gear Z will then rotate with the shaft L. The op erator will then release lever Q, permitting the wedge Q to descend into the groove 10. When the bevel-wheel Z has nearly completed a single revolution, the wedge Q will engage the shoulder 19 of the bolt 19 and withdraw the bolt from the notch or recess in the gear 1*, thus releasing it just as it completes its revolution, whereby the load in the scoop has mounted in bearings secured to the main frame and provided at each side with a cam R for elevating the arms K K and the scoop. Each of said arms'K K is provided, preferably, with a friction-roller 70 engaging one of the cams R, as clearly shown in Fig. 3. On the shaft R is loosely mounted a gearwheel r, meshing with a gear-wheel 1* on the shaft L. I provide a clutch mechanism for connecting the gear-wheel r to shaft R, so as to give the shaftR a half-revolution at a time, and the cams R R are so arranged that one half-revolution of the shaft R will elevate the arms K K and the scoop to their highest position, and the other half-revolution will allow the scoop to descend to its lowest position. For this purpose I employ a clutchwheel R mounted on shaft Rand constructed exactly similar to the clutch-wheel P, having a bolt 'r adapted to engage a notch or recess in the hub of the gear-wheel rt I, however, provide two wedges 7' '1 located at opposite sides of the shaft, so that the bolt 2" will be withdrawn when the shaft has made a halfrevolution.

In Fig. 7 I have shown the two wedges 1' 7' mounted on spring-arms r W, respectively, and an, arrangement for throwing one of said wedges out at a time to allow the shaft R to makea half-revolution.

S represents a hand-lever pivoted on the rear platform and connected by a link 8 to one arm of a bell-crank lever s, the other arm being provided with a stud s to engage and lift the spring-arm r and wedge r This bell-crank arm is connected by a link :5 to a pivoted arm 3 provided with a stud s adapted to engage'the spring-arm r and move the wedge r out of the path of the bolt 1'. From thedrawings it will be seen that by moving the lever S in one direction one of said wedges 7' T will be moved out of operation and the other into operative position, and by moving it in the opposite direction the positions of the wedges will be reversed. Thus the'shaft R can be readily given a half-revolution to elevate the scoop, and when desired by moving the lever in the opposite direction the shaft R can be given another half-revolution to lower the scoop.

The motor will be supplied with current from a trailing wire or in any other desired way and will be operated ,by controller T, mounted on the machine conveniently to the operator. The apparatus will be moved up to a pile of dust, gravel, or other matter which it is desired to remove and with the scoop lowered will be driven into it until the scoop is filled. The operator will then throw out the clutch c and stop the driving shaft and wheel, after which he will operate the lever S so as to impart a half-revolution to the shaft R and raise the scoop to its highest position. The clutch 0 will then be thrown in full revolution to shaft 0 and thereby dump the contents of the scoop. The machine can then be run back to the desired point, the scoop lowered, and the operation repeated.

This apparatus is particularly advantageous in removing ore, 00., from horizontal shafts, although it can be used for'other purposes as well.
