SCRAPER.

Application medium 1.

This invention relates to improvements in scrapers and particularly to one of small size and capacity particularly adapted to be used in connection with check filling. In making checks on land one check as being made cuts through another transversely disposed check already made, as is well known. It is therefore necessary for the opening in one check or the other to be filled in.

The principal object of my invention therefore is to provide a scraper for this purpose which may be easily moved over the ground and readily manipulated by hand so as to both steer the scraper and also to cause the bowl of the implement to scrape, dump or ride idly, as may be desired.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a perspective elevation of the scraper.

Fig. 2 is a sectional elevation of the same.

Referring now more particularly to the characters of reference on the drawings the numeral 1 denotes a pair of longitudinal transversely spaced side frames connected at their front end by a crossbar 2 to which a .clevis 3 is connected for attachment to the traces of a draft animal. Pivotally mounted between the frames at their rear ends are ground engaging discs 4 connected to and extending between which for a predetermined portion of the periphery thereof is a curved plate 5 forming a scraper and dirt retaining blade; said plate and discs together forming the bowl of the implement.

Secured to the side frames ahead of the bowl is a transverse rod or shaft 6 on which are turnably mounted the forward ends of a pair of transversely spaced handle bars 7. These bars extend over and rearwardly of the bowl a certain distance and are connected together Extending between the discs 4 above the plate 5 is a rigid rod 8, which projects at its ends through any transversely alined pair of holes 9 drilled through the discs 4 adjacent the periphery thereof, said holes being disposed Serial No. 195,639.

t-mar of a vertical line I projected through" axis of said discs. The handle barsrc Intermediate their ends on said rod, and pie erab'ly have metal plates 101m their under faces to take the wearot contact with said rod. Rigid stops 11 depend from the handles adjacent the forward ends of the plates, said stops, when the plates engage the bars, projecting in front of the cross rod 8.

In operation it will be seen that when the handle plates rest on the rod 8, the bowl is held immovable and prevented from rotation in the direction normally had with the forward movement of the implement. The rod is positioned so that the blade A will then properly engage the ground, and the bowl will fill with dirt. lVhen the check is reached, the raising of the handles so that the stops 11 clear the rod 8, will cause the bowl to upset forwardly. Said bowl then rides on the discs (which practically form wheels) and causes the dirt to be dumped in the opening in the check. The handles are of course raised sufficiently so that the cross rod and bowl-blade will not strike the handle-bars when the bowl rotates. If it is not desired to pick up a load the handles are maintained in this raised position, and the discs will then simply'revolve freely with the forward movement of the implement.

The provision of the stop members 11 eliminates the need of any downward pressure on the handles being exerted when the stops are once engaged with the rod 8, since the natural tendency of the bowl to rotate holds the said rod firmly against the stops and prevents release of the handles.

' The handles are of suflicient length and v strength relative to the structure as a whole that they serve to steer the implement one way or the other as may be needed.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

WVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

7 Having, thus described my'invention what I claim as new and useful and desire tosecure by Letters Patent is 1. A scraper comprising a frame to be moved along the ground, a rotatable bowl Ian member-pivoted onto the frame, a handle member pivoted onto the frame ahead of the bowl and extending forwardly thereof, a cross member mounted in fixed connection with the bowl rearwardly of the pivotal point thereof and on which the handle rests, and a stop member fixedon the handle and depend ing therefrom so as to be normally ahead of and in the path of travel of the cross member.

moved along the ground, a rotatable bowl member pivoted onto the frame, a handle 2. A scraper comprising a frame to be 3. 'A structure as in claim 1, in which said 7 cross member is circumferentially ad ustable about the bowl, whereby to enable the setting of the blade of thebowl relative to the handles to be altered at will.

In testimony whereof I aflix my signature. JOSEPH H. HALE.
