SCRAPER.

SPECIFICATION forming part of Letters Patent No. 740,087, dated September 29, 1903.
Application filed September 18, 1902. Serial No. 123,870. (No model.)
_________________
To all whom it may concern:
Be it known that I, JOHN W. CARLETON, a citizen of the United States of America, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.
The embodiment of the invention illustrated and described herein is in the form of a scraper for use in scraping floors, &c.
The object of the invention is to permit of a wide adjustment of the handle with respect to the blade.
It is clear that the invention is applicable to other uses than to scrapers.
Referring to the drawings, Figure 1 is a side view of a scraper. Fig. 2 is a front view of the same. Fig. 3 is a rear view. Fig. 4 is a top view with part of the hand-rest broken away.
Referring to the drawings, A denotes the blade; B, a clamping-head having on one side a threaded pin C, which projects through a hole in the blade and is engaged by the thumb-screw D, which bears on a washer E. The rear of the clamping-head B has the lug F, one side of which is milled, as at f in Figs. 3 and 4. The handle G is provided with a disk H, one face of which is milled to fit the milling on the lug F. The handle is held to the lug by the pin J and the thumb-nut K. On the upper edge of the plate is located a hand-rest M, to which is secured a strap N, which enters a recess in the washer E to prevent the hand-rest from slipping side-wise off the blade. It is readily seen from the drawings that the handle is capable of adjustment in a plane at right angles to the blade by turning it on the pin J and securing it in place by the thumb-nut K, also that it is adjustable in a plane parallel to the blade by turning the handle and the clamping-head B about the axis of the pin C and maintaining it in position by means of the thumb-nut D. Thus I am enabled to so adjust the handle of the scraper that it may be used under any and all conditions — as, for instance, against the base-board when scraping a fioor. I am aware that other devices have been produced for accomplishing this object; but they are expensive to manufacture. They are difficult of adjustment.
The device herein shown and described is very inexpensive to manufacture and can be readily adjusted and used by any one.
I claim as my invention —
In combination with the clamping-head, a lug carried thereby, a pin oppositely disposed on said lug, and a handle adjustably connected to said lug, a blade mounted on said pin, a washer engaging the outer face of said blade, a locking means frictionally engaging the said washer, a hand-rest carried by the blade, and a strap carried by the said hand-rest and engaging a recess in the said washer, substantially as and for the purpose specified.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN W. CARLETON.
