EARTH sooor.

Application filed September 17, 1925.

To all whom it may concern: 7

Be it known that I, DANIEL P. SENGER, a citizen of the United States, residing at Minot, in the county of Vard and State of North Dakota, have invented certain new and useful Improvements in Earth Scoops;

'andl do declare the following to be afull,

type which is not provided with wheels, but

merely slides along the ground, and the invention resides primarily in novel dumping means for such a scoop.

One object of the invention is to provide a dumping means which may be easily and inexpensively manufactured and may be readily applied to a scoop, the construction being such that this dumping means may be readily brought into play whenever desired.

The dumping means includes a pair of earth-engaging, scoop-dumping arms dis posed at the sides of the scoop, and a further aim is to provide unique guiding yokes for these arms, which yokes prevent lateral displacement of the arms as well as limiting their upward and downward movements.

Figure 1 of the accompanying drawings is a side elevation of a scoop embodying the invention, showing the relation of parts when the load is being collected or hauled.

Figure 2 is a view similar to Fig. 1 but illustrating the manner in which the dumping means is active to cause overturning of the scoop to discharge its contents.

Figure 8 is a top plan view.

F igure at is a vertical transverse section on line lt of Fig. 1.

I have shown my improvements in connection with a scoop or scraper of the well known Fresno type, in which the opposed side walls S of the scoop are provided with runners B, said runners being connected by a transverse bar B which extends over the scoop body. Projecting rearwardly from the rear wall of this scoop body, the usual handle H has been shown.

T ransversely alined bearings 1, of any suitable form, are secured to the rear side of the wall V, and in these hearings a transverse rock shaft is mounted, said shaft preferably comprising two sections 2 and 3, the inner end of the section 2 being bent rear- Serial No. 56,997.

wardly to provide a handle 4 disposed adjacent the handle H, while the inner end ofthe shaft section 3 is rearwardly bent as at 5 and secured by bolts or the like 6 to the front portion of said handle at. The outer ends of the shaft sections 2 and 8 are pro.- vided with forwardly projecting scoop dumping arms '7, preferably formed integrally with said shaft sections. as sho.wn.1

Thesearms are disposed at the sides of the scoop and they pass through guide yokes8. which hold them against lateral displace.- mentand limit their upward and downward movements.

with the arms 7, while the upper ends of said springs are attached, in the present disclosure to the bar B. These springs exert their tension to normally raise the arms 7 against the upper ends of the yokes 8, but when the handle 4 is pulled upwardly, the front ends of said arms 7 are caused to move downwardly, so that they can penetrate the earth and cause easy dumpingv of the scoop, it being of course understood that the latter is provided with any of the well known draft means by which the real dumping operation is effected when the front end of the scoop is held against forward movement by Coiled, tension springs 9 have; their lower ends suitably connected at 10- the arms 7. Each of the yokes 8 comprises a vertical upper portion 11, and a vertical lower portion 12 laterally offset from said upper portion. The portion 11 lies against the outer side of the wall S and has its upper extremity bent laterally inward as at 13 over the upper edge of said wall, and then bent downwardly as at lat into contact with the inner side of the wall. The lower extremity of the portion 12 is bent laterally inward toward the wall S as indicated at 15, is then bent at right angles in another direction, Jreferably upwardly, to provide a shoulder 16 which abuts the outer side of the wall S, and is finally bent again inwardly to providean attaching stud .17, which stud passes through an opening 18 in the wall S and is provided on its inner end with a nut 19 or some other adequate shoulder. By constructing the yoke in this manner, it may be easily and inexpensively manufactured, quickly and easily attached, and will well perform the functions for which it is designed.

As excellent results are obtainable from the details herein disclosed, such details are preferably followed. However, within the scope of the invention as claimed, modifications may of course be made.

I claim:

1. In a scoop having a rearwardly projecting handle; a transverse rock shaft mounted on the back wall of said scoop and provided with a r-earwardly projecting handle, scoop-dumping ground-engaging arms projecting forwardly from said rock shai't at the sides of the scoop, yokes carried by said sides of the scoop, said arms passing through said yokes for vertical movement, and spring means for normally raising said arms against the upper ends of the yokes.

2. In a scoop having a rearwardly projecting handle; and provided with runners at its sides connected by a transverse bar; a transverse rock shaft mounted on the back wall of said scoop and provided with a rearwardly projecting handle, scoop-dumping ground-engaging arms projecting forwardly from said rock shaft at the sides of the scoop, yokes carried by said sides of the scoop, said arms passing through said yokes for vertical movement, and tension springs connecting said arms with the ends of said transverse bar to normally raise the arms against the upper ends of the yokes.

Ina scoop having ground-engaging dumping arms at its sides; guiding yokesfor said arms each comprising a single metal rod having an upper portion lying against a side wall of the scoop and a lower port-ion outwardly offset from said upper portion, the upper extremity of said upper portion being bent laterally inward over said wall and then downwardly in contact with the inner side of said wall, the lower extremity of said lower portion being bent laterally toward said wall, then bent in another di rection to provide a shoulder contacting with the outer side of the wall and then bent again laterally to form an attaching stud, the latter passing through the wall and having a shoulder engaging the inner side of said wall.

In testimony whereof I have hereunto atfixed my signature.

DANIEL P. SENGER.
