CHARLES S. DIKEMAN, OF NORWALK, CONNECTICUT.

CABINET AND FLOOR SCRAPER.

Specification of Letters Patent.

Application filed April 4, 1911.

Patented Oct. 22,1912.

Serial No. 618,953.

To all whom it may concern:

Be it known that I, CHARLES S. DIXIE- MAN, a citizen of the United States, and resident of Norwalk, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Cabinet and Floor Scrapers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in cabinet and floor scrapers, and it consists in the parts and combinations of parts and in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my improved tool. Fig. 2- is a view in rear elevation of same. Fig. 3 is a view looking toward the clamping jaws from the handle end of the tool. Fig. 4c is a view in central vertical section and Fig. 5 is a view in horizontal section.

1 represents a frame having reduced or narrowed ends which latter are bent at right angles to the body and form the ears 2. Secured to this frame 1 is the fixed clamping plate 8, which latter extends from one ear 2 to the other, and projects above and below the plate 1, so as to provide for some elasticity. The free upper and lower edges of the plate are preferably bent rearwardly as at 4 so as to bring the free or clamping edges of the plate, in a plane to the rear of the central portion thereof, and the plate is secured to the frame 1 by rivets 5, and also by the shank of the stem or fixed section 6 of the handle, which shank is passed through a hole in the frame 1 and also through plate 8 and is upset on the rear side thereof, thus permanently securing this section of the handle to the frame 1 and also to the fixed clamping plate 3. The fixed end 6 of the stem is provided with a spherical head 7 on which the internally threaded sleeve 8 is mounted, the said sleeve having a reduced opening at its rear end for the passage of the stem 6 and an enlarged opening at its front end for the entrance of the threaded nut 9. This sleeve is placed on the shank of the stem 6 of the handle before the latter is secured to the frame 1, hence after the parts have been assembled and secured, this sleeve will be permanently attached, and while it has free movement on said stem 6 it cannot be removed without destroying the tool. The inner surface of the rear end of the sleeve is rounded or concavely curved to closely fit the spherical head of the nut, and its front end is internally threaded to receive the externally threaded end of the nut 9; this nut 9 is dish-shaped at its rear end to engage the spherical end of the fixed section of the handle, and is also internally threaded to engage the bolt 10 of the removable and adjustable section 11 of the handle. This bolt 10 is cup shaped at its front end to engage the spherical head, and is adapted to engage the same for rigidly locking the stem to the handle. By turning the handle section 11 in a direction to disengage bolt 10 from the head 7, it will loosen up the parts so that sleeve 8 may be turned and adjusted so as to locate the handle at any desired angle, up or down, and sidewise, thus giving proper position to the parts for scraping floors, doors, casing or wainscoting, and by simply turning section 11 of the handle in a direction to force the bolt 10 against the head 7, the parts will be locked in their adjusted positions, by the contact of the sleeve 8 at the rear of the head 7, and the bolt 10 against the front of said head.

Loosely mounted on the rearwardly projecting ears 2 is the movable clamping plate 12. This plate conforms in size and shape to the fixed clamping plate 3, and is bent at 4 similar to the fixed plate and for the same purpose. The plate 12 is provided at its side edges with laterally projecting lugs 13 arranged in pairs and resting against the top and bottom surfaces of the ears 2, for guiding plate 12 in its movements and for holding it in position when not engaged with a scraper, and is also provided on its rear face with the loop shaped hand rest 14, which latter projects rearwardly from plate 12 so as to be engaged by one hand of the operator. The ends 15 of the hand rest 14 are bent at right angles to the rest proper and are permanently secured to plate 12 by rivets.

Mounted in the ears 2 of frame 1, is

the cam locking bar 16, having a finger piece 17, by which it may be turned to engage or disengage the ends 15 of the hand rest against which the locking bar 16 bears. The scraping tool 18 is placed between the two jaws, and is firmly clamped therein by the locking bar 16, with its two edges projecting beyond the plates. I prefer to have one edge of the scraper for rough work, and the other for finishing, but this is not material, as the principal object in having both ends of the scraper project is that it can be reversed.

In operating the tool, the operator grasps the handle 11 with one hand, and the hand rest with the other, the hand on the hand rest serving to hold the tool down to its work, while the other hand simply drags it over the surface. By locating the hand rest near the cutting edge of the blade, a natural. and easy means is provided for carrying the tool back and forth, thus relieving the other hand and wrist doing the pulling or pushing, of all strains necessary to hold. the cutter down to its work.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I. do not wish to confine myself to the exact construction and arrangementof parts shown and described, but

Having fully described my invention what 1 I claim as new and desire to secure by Letters-Patent, is

1. In a scraper, the combination with a frame, a clamping plate fixed thereto, and a handle section, the shank of which passes through the frame and plate, and upset at its end against the latter, the said handle section having a spherical head, of a sleeve loosely attached to said handle sect-ion and embracing the head, a nut secured within the sleeve and a handle section having a bolt engaging the internal threads of the nut and hearing at its end against the rounded head of the other section of the handle.

2. In a scraper, the combination with a frame having rearward projections at its ends, a clamping plate rigidly secured to said frame, a clamping plate mounted to move on the rearward projections of the rigid clamping plate, and provided on its rear or outer face with a hand rest, a cutter located between said clamping plates and projecting at opposite sides of same and means for clamping the cutter between, said clamping plates, of a handle detachably and adjustably secured to the front face of the frame.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
