To all whom it may concern:
Be it known that I, NOBLE KELLER, a citizen of the United States of America, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a certain new and useful Scraper; and l 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.
This invention relates to a scraper and has among other objects, to provide a tool of this description, of simple and cheap construction which shall be efficient and durable in use and wherein the cutting blade can be readily formed, without the use of tools, other than those usually possessed by the user of the device.
It is also an object to provide a scraper that can be worked close up to any projection perpendicular to the surface on which it is used.
Another object is to provide means for easily adjusting the scraper blade.
A further object is to provide a scraper of such form that it can be readily grasped and pressure applied thereto without fatiguing the hands of the operator.
Still another object is to provide a scraper in which the blade need not be removed to sharpen the same.
One form in which this invention may be embodied, is herein described and is illustrated in the accompanying sheet of drawings, in which —
Figure 1 is a side elevation, and Fig. 2 is a rear elevation with portions broken away.
A handle 1 is fitted into a tubular socket 2, being retained therein by a pin or rivet 3. The rearward end of socket 2 has a downwardly deflected flattened portion 4, to which is attached by screws 5, a bolster 6, prefer-
ably formed of wood or other slightly yielding material. The lower portion of bolster 6 has a rabbet 7, which receives the upper portion of a blade 8, said blade being held frictionally between bolster 6 and a back plate 9, by means of bolt 10, which passes through a slot 9a in back plate 9, bolster 6, and downwardly deflected portion 4 of the handle, and has on its forward end, a nut 11. The sides of blade 8 may be beveled and sharpened in the same manner as the bottom of said blade. Blade 8 is preferably wider than back plate 9 and bolster 6. It may be formed of any convenient piece of sheet metal, such as an old saw blade, and there being no holes through it, it can readily be made with such tools as are usually carried by a wood worker.
The mode of operation of this invention is as follows: Handle 1 is grasped by one hand of the operator, while the other hand rests upon the top of bolster 6 and back plate 9. These parts being designed as shown, the hand rests easily upon this portion of the assembled tool and pressure may be applied without great fatigue to the operator.
The scraper is used by drawing it along the surface to be scraped, in the usual manner, as will be readily understood by those skilled in the art to which this invention appertains. In working close to vertical surfaces, the scraper may be laid upon its side and the ends of the blade used. In such use of the device, it will be readily understood that the handle extends away from the vertical surface, so that there is a sufficient clearance to enable the operator to manipulate the device conveniently. The blade 8 may be protruded, as it becomes worn, by striking on the upper sides of the projecting portions.
I claim:
1. A scraper comprising ahandle having a widened portion at the lower end thereof, a wooden bolster affixed to said portion, a back plate, said bolster and said plate suitably shaped to afford a hand-rest thereon when the same are assembled, a single bolt having a nut threaded thereon and passing through said plate, bolster, and widened portion of the handle, whereby the blade may be clamped between said bolster and said back plate.
2. A scraper comprising a handle, a metal tube affording a socket for said handle and having a flattened part bent at an angle to said socket, a wooden holster secured to said flattened part, said bolster shaped to afford a hand-rest thereon, and having a out-away portion to accommodate a blade, a slotted back plate, a single bolt having a nut threaded thereon and passing through said plate, bolster, and flattened part, whereby the blade may be clamped between the bolster and the back plate.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses at Los Angeles county of Los Angeles, State of California this 31st day of December A. D., 1907.
NOBLE KELLER.
