EXCAVATING SCOQP I Specification of Letters Patent. Application filed eptemter 8,1906. Serial No. 333,769.-

Patented May 7, 1907.

To all whom it may concern."

Be it known that I, RUssELL WILES, acitizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a new and useful Excavating.

the accompanying drawings, in which Figure 1 is a side elevation of my improved scoop and Fig. 2 is a top plan thereof:

Referring to the drawings, A is asuitable shovel, which is pivotally secured to and supported by a supporting bail, B, the pivotal connection between shovel and bail being be.

hind the center of. gravity of the shovel, so that when the shovel is released its forward end will swing downward to dump its con tents. The supporting bail, 13, carries at its upper end two sheaves, over which pass ropes, C, the lower ends of which are'connected to a ring or other suitable fastening device, a, secured to a bridge which extends across the front end of the shovel, said. ropes being led from said ring over the sheaves and thence outward through eyes, a, at the front corners of the shovel, and thence forward, where they are joined together at 6, being continued from their junction point in the form of a single hauling-rope, which runs over the Winding drum of an engine or other suitable power device. Each of the ropes, (1, is provided with a button, 0, between the eye through which it asses and the sheave over which it runs, sai button being in such position on the ro e that when it is in contact with the eye t 1e shovel will be in substan tially a horizontal position.

In the operation of my improved scoop the scoop is drawn forward through the material to be operated upon by means of the haulingrope, and during this portion of the operation the buttons will be drawn a ainst the eyes so thatthe propelling force wil be exerted upon the shovel by thebuttons, and the shovel will be held in a substantially horizontal position by means of the ropes which. connect the buttons with the .eye, (H, on the shovel. After the shovel has been filled it is raised by means of the supporting bail and moved to the positioawhere it is desired to dump it, the hauling-rope being maintained -taut to hold the shovel horizontal. When it is desired'to dump the shovel the tension of swings down, the buttons simultaneously moving up towardthe sheaves and the ropes sliding through the eyes.

It will be observed that this construction is exceedingly simple and accomplishes its purposewithout certain of the complexities of other forms. of scoops now in use. It, will also be observed that the eyes, (0 are curved, as shown in the'drawings, so as to conform to the course of the ropes and are flared outwill be presented to the ropes whereby undue and unnecessary friction will be exerted thereon.

I realize that considerable variation is possible in the details of this construction, without departing from the spirit of my invention, and I do not intend, therefore, to limit myself to the specific form herein shown and described.

I claim as new and desire to secure by Letters Patent 1. The combination with a shovel having a cutting edge at its forward end and a supporting bail pivoted to the shovel behind the center of gravity thereof, of a hauling-rope and stationary device on the front of the shovel through which said rope passes, said rope having a connection with the supporting bail and an engagement device on the rope adapted to cooperate with the portion to limit the relative movement of the rope therethrough.

2. The combination with a shovel having a cutting edge at its front end and a supporting bail pivoted thereto behind the center of gravity thereof, of eyes secured to the shovel, ropes passing through said eyes and having connection with the hauling-bail, and projections on the ropes adapted to engage the eyes.

3. The combination with a shovel having a cutting edge at' its forward end and a supporting bail pivoted thereto behind the center of gravity thereof, of an eye on the shovel, a rope passing thercthrough, a sheave sccurer to the supporting bail, over which sheave'the rope passes, said rope being sothe hauling-rope is released and the shovel ward at their ends so that no sharp angles.

of the shovel through which the rope passes,

cured to the shovel in front of its pivot, and e suitable engagement device upon the rope to engage the e e. I

4. the combination with a, shovel having a outtln edge at its forward end and e supporting hail pivoted thereto behind the center of gravity thereof, of eyes at the front of the shovel, sheaves on the supporting ball,

ropes passing through the eyes and over the sheave and secured to the shovel in. front of its pivot, and projections upon the ropes .edepted to engage the eyes.

5. The combination with a shovel having a cutting edge at its forward end and e sup porting bail pivoted thereto behind the oenter of gravity thereof, of sheaves on the sup-- l porting hail, curved eyes at the front of the shovel, the upper ends of which point t0- werd the sheaves and the lower ends of which point forward, ropes passing through the eyes and over the sheaves and having connection with the shovel in front of its pivot,

and stops on the ropes adapted to engage the eyes. r v

In witness whereof, I have signed the above application for Letters-Patent at Chi-
