Specification of Letters Patent.

Patented May 27, 1919.

Application filed April 18, 1918. Serial No. 229,328.

To all whom it may concern:

Be it known that 1, DAVID E. ENLoE, a citizen of the United States of America, and resident of River Falls, in the county of Pierce and State of WVisconsin, have invented certain new and useful Improvements in Levelers, of which the following is a specification.

This invention relates to earth workers and particularly to a device for packing and smoothing soil or snow on roadways, said invention being also convertible as a harrow for treating soil.

An object of this invention is to produce a device which can be attached to a draft medium, whereby it will operate to pack soil or made to pack snow evenly over the roadbed, obviating ruts and unevenness produced by traveling vehicles over the road.

It has been found in practice that snow covered roads treated with a device of this kind proved more satisfactory in rural districts than where the snow is removed even though it were possible to so remove the snow covering large mileage as there is a tendency for the snow to drift and of course it quickly lodges in that portion of the road which is excavated or from which the snow has been removed.

A further object of this invention is to provide means for transporting the pressing and leveling members free of the surface of a road over which the device is traveling when occasion requires, novel means being provided for elevating and lowering the pressing members.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a plan view of a device embodying the invention;

Fig. 2 illustrates a side elevat on; and

Fig. 3 illustrates a rear end view thereof.

In these drawings 5 denotes sled runners on which the operating parts of the mechanism are supported, the said sled runners being connected bya beam 6 secured to the runners by clips 7. The beam has a plurality of I-bolts 8 extending through it and smoothing planes 9, 10 and 11 have clips 12 attached to their forward ends and the said clips are pivotally connected to the I-bolts so that the planes may have certain degree of free movement to permit them to pass over uneven surfaces of a road or over soil to be treated.

The smoothing planes in the present embodiment of the invention comprise longitudinally extending side strips 13 and transversely disposed plates or planks 14 which may be of metal or wood, secured to the strips by fastenings such as lag screws 15 although any appropriate fastenings may be substituted in this regard.

There is a series of transversely disposed angle irons 16 attached to each plane and they have apertures 17 which register with apertures 18 in the transversely disposed strips for the admission of barrow teeth 19, the said harrow teeth being clamped to the angle irons at different positions of adjustment by clips 20 so that when the harrow teeth are not to be used, they may be entirely removed or they may be adjusted so that their lower ends do not project below the planes.

Each plane has a bracket 21 attached to its upper surface and a link 22 is pivotally connected to it, the said link having its upper end connected to a crank shaft 23, which crank shaft is journaled in bearings 24 attached to plates 24 and the plates are secured to the sled frame by bolts 24 or the like. The crank shaft is partially rotated by a handle 26 secured on it and the operating handle may be held at different positions of adjustment by a detent 27 which engages the toothed segment 28 carried by the frame of the sled so that by the operation of the handle, the planes may be elevated or lowered as heretofore indicated.

Braces 29 extend longitudinally of the runners and are connected to them and said braces also are attached to the frame 25 so that a rigid structure results.

The runners are further connected at the front by a tongue-like member 30 and the said tongue like member has a coupling 31 by which it may be attached or hitched to a draft means, that is to say to an automobile or sled or horses may be used for pulling it.

The device can be used as a harrow, preferably by disconnecting it from the sled and providing any appropriate 7 means by means for elevating and lowering the planes Which horses can be hitched to it. angle irons extending transversely of the I claim: 7 planes, said angle irons and planes having 10 In a leveler, a sled, a beam extending apertures therein,- and teeth extending 5 across the front thereof, planes extending through the apertures and means for atrearwardly from the said beam, means' for taching the teeth to the angle irons. loosely connecting the planes to the beam, DAVID E. ENLOE.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
