Mar W. J. sTAcHowlAK SCRAPER Filed July 2, 1940 In ventor MAL/AM cf JT/ICHOW/A/f A itorneys Patented Mar. 25, 1941 UNITED STATES SCRAPER William J. Stachowiak,
Huntington Bark, Calif.
Application July 2, 1940, Serial No. 343,657
4 Claims.
The present invention relates to new and useful improvements in hand scrapers and has for itsprimary objectto provide, in a manner as hereinafter set forth, an implement of this character comprising a blade which is adapted to be expeditiously adjusted to compensate for wear as it occurs and which may be removed for replacement when desired.
Another very important object of the invention is to provide a scraper of the aforementioned character comprising unique means for releasably securing the blade in adjusted position.
Other objects of the invention are to provide a scraper of the character described which will be comparatively simple in construction, strong,
durable, highly efficient and reliable in use, compact, light in weight and which may be manu factured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a top plan view of a scraper constructed in accordance with the present invention.
Figure 2 is a view in side elevation thereof, a portion of the stationary plate being broken away in section.
Figure 3 is a bottom plan view of the blade clamp.
Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a socket l which is secured in any suitable manner on one end portion of a handle 2. Fixed on the socket l and projecting longitudinally therefrom is a plate 3 of suitable metal which is provided with a beveled forward edge 4.
Adjustably and removably mounted on the plate 3 is a scraping blade 5 of suitable metal. The blade 5 is secured in adjusted position on the plate 3 through the medium of a clamp comprising a plate 6 having a beveled forward edge I. The lower or inner face of the clamping plate 5 is transversely grooved in a manner to form what may be considered ratchet teeth 8. The blade 5 is provided with an angularly extending flange or lip 9 on its rear edge which is engageable selectively with the ratchet teeth 8.
The clamping plate 6 further includes a curved rear end portion H) which is adapted to bear on the adjacent portion of the stationary plate 3 in abutting engagement with the forward end of the socket I. Bolts. ll in the rear portionof the stationary plate 3 pass through the clamping plate 6 and'are provided with wing nuts I2 for clamping said plate 6 to said plate 3 in a manner to firmly grip the blade 5 therebetween.
It is thought that the manner of using the device will be readily apparent from a consideration of the foregoing. Briefly, with the lip 9 engaged with one of the ratchet teeth 8 in the manner clearly shown in Fig. 2 of the drawing and with the wing nuts tightened on the plate 6, the blade 5 is firmly secured in adjusted position. To adjust the blade 5 to compensate for wear as it occurs on the scraping edge thereof, the wing nuts 12 are backed offin a manner to loosen the plate 6 thereby permitting the lip 9 to be en.- gaged with another of the teeth 8, after which said wing nuts are again tightened. Owing to the fact that the clamping plate 6 is in abutting engagement with the forward end of the socket l the longitudinal thrust or strain from the blade 5 when the tool is in use is transmitted directly to said socket, thus relieving the bolts II.
It is believed that the many advantages of a scraper constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:
1. A scraper comprising a handle, a socket mounted on one end portion of said handle, a stationary plate mounted on said socket, a clamping plate mounted on the stationary plate and including an arcuate end portion bearing on said stationary plate and abutting one end of the socket, the clamping plate further including a plurality of ratchet teeth extending transversely across its inner face, a scraping blade removably and adjustably mounted between the plates, an angularly extending lip on one end of the blade engageable selectively with the teeth, bolts mounted on the stationary plate and passing through the clamping plate, and nuts on said bolts for tightening the clamping plate on the blade.
2. A scraper of the class described, comprising a handle, a stationary plate carried by said handle, a blade clamping plate mounted on the stationary plate and provided with an arcuate end portion bearing on said stationary plate,
ed on said socket, a clamping plate mounted onthe stationary plate and provided with an arcuate end portion bearing on said stationary plate and abutting one end of the socket, said clamping plate further provided with a plurality of ratchet teeth extending transversely across its inner face, a scraping blade removably and adjustably mounted between said plates, said scraping blade provided with an angularly extending lip at one of its ends to selectively engage the said teeth, and means for tightening the clamping plate and blade on the stationary plate in adjustably secured position.
4. A scraper of the class described, comprising a socket having stress and strain receiving and distributing abutment means, a scraper blade backing and guard member rigidly carried by said socket, a blade accommodating and clamping member opposed and separably joined to said guard, said clamping member having on its inner face selectively usable shoulder forming elements functioning to aid in sustaining a blade in progressively projected positions, said clamping member also having a strain and thrust transferring abutment releasably engaging the stated abutment means, and a projectible and retractible scraper blade interposed between said guard and clamping member, the inner end of said blade being laterally deflected to provide a flange-like retention lip selectively engageable with said blade sustaining shoulder elements.
