HAND SCRAPER Filed Jan. 6, 1939 In uerzt'or Jolz z JAnde/wvrz Patented Oct. 29, 1940 UNITED STATES HAND SCRAPER John S. Anderson, Chicago, Ill.

Applic 1 Claim.

This invention relates to hand scrapers and is used particularly in instances where the pores of the hand become clogged with foreign matter, especially where the hands are used for me- 5. chanical work and are constantly impregnated in oils andgreases which imbed themselves into the pores of the hand and cannot be washed thoroughly in the ordinary manner with soap and .water.

-An important feature of my invention is the provision of a series or a multiplicity of flexible scraper blades, arranged on a surface of arcuate configuration in order to attain the purposes intended.

Another object of the invention is the provision of a simple, efficient, useful article of manufacture which is also economical to manufacture in quantity production.

Other advantages may become apparent by re- 20 ferring to the accompanying drawing and the ensuing description, wherein like symbols are used to designate like parts and in which:

Fig. 1 represents a perspective view showing how my hand scraper invention is utilized in 25 cleaning the palms of the hands.

Fig. 2 is a perspective view of my device, showing particularly the operating portion thereof.

Fig. 3 is a cross-sectional view on the line 3-3 of Figure 2.

Fig. 4 is a bottom plan View Fig. 5 is a longitudinal cross the line 5--5 of Figure 3.

Mechanics and repairmen engaged in repairing automobiles or other machinery or equip- 35 ment, constantly, are troubled with the condition that their hands cannot be kept absolutely clean. It is absolutely necessary for a mechanics hands to be constantly working on oily parts and greasy parts and since use of his hands is mandatory under such circumstances, a great deal of oil and grease lodge in the pores of the hands. At the end of the day when the mechanic is thru with his work and is desirous of cleaning his hands there being no suitable cleaner on the market 45 which will actually enter the pores of the skin and remove all matter which has accumulated therein, the inevitable result is that the imbedding of this foreign material becomes more and more deep rooted from time to time, and

50 hardens within the pores whence its removal becomes more and more diflicult.

My invention is to provide a device which can be used during the day or at the end of the days labor, so that a mechanic may be able to use the 55 scraper that I have provided in removing. all the of my invention.

foreign substance which has lodged in the pores. This operation being performed at the end of the day before it has an opportunity to harden in the pores with the resulting disastrous effect of chapping and otherwise disfiguring the epidermis.

The nature and construction of the invention is such as to provide a multiple series of flexible scraper blades, in order to more effectively scrape off the material clogged in the pores of the hand, soap and water being used in addition or as regularly employed during the process or operation, the soap and Water tending to dilute and soften the particles of oil and grease thus facilitating their removal.

Referring to the various figures in the accompanying drawing and especially Figure 2, I show my invention generally designated by the numeral 6 having an arcuately shaped top portion designated by the numeral 1, and the approximate arcuate contour indicated by the numeral 13. "This top portion 1 is provided with a series of scraper blades 8 whose ends are rounded off so as to have no sharp points which might scratch or otherwise irritate the skin when this device is applied to it.

These blades 8 are produced by stamping them from the surface I and are bent at the point H5 at right angles to the point of tangency of the arcuate surface 1. The blades being bent to the shape shown as illustrated, will providein the top surface I, the openings 9 from which the respective blades have been formed. The top surface is drawn from one piece of sheet metal, and provided by suitable dies, with the sides l0, and the sides I I.

As will be noticed vided with knurls, or impressions the sides II are also prol2 which are to provide suitable gripping means for the hands when this device is being grasped in one hand to be used upon the other, remembering that the hands, at such time, are moist, soapy and rather slippery. The serrations l2 are stamped right out of the metal simultaneously, when the shape of the arcuate portions are formed, and the blades are cut and formed.

After the article ismade up to this point then the side walls Ill, and II are bent on the line H and mitered at the point IS in order to provide? the surfaces l4 and I4. Thus in closing up the portion on the top surface it is possible to grip this device in the hand without injury, as there are no rough edges'protruding and hence makes for a simple, cheap, and compact articlemade from one piece of metal.

By virtue of the elongated opening l8, and the openings designated by the numeral 9, it is very easy to run water thru this article and clean it of all foreign matter after a scraping operation, thus permitting of keeping this article clean at any and all times.

This article may be made preferably of springy material, such as French steel, or, perhaps, Monel metal, or stainless steel so as to prevent corrosion, or it may be made of standard steel stock, and nickel plated or chromium plated depending on the requirements.

Altho the device has been shown more or less of a size in proportion to the human hand, this article may be otherwise dimensioned without affecting the utility thereof, and may be made of any other similar or suitable material mentioned heretofore.

In application or use, the article is preferably gripped as shown in Figure 1, between the thumb and fingers of the one hand, the hand being more or less in relatively right angled position when the operation of scraping takes place, as is illustrated very clearly in Figure l, and as mentioned heretofore. After the scraping operation has been completed, the device may be completely Washed, cleaned, and dried by spraying with a hose or under the ordinary pressure of a water tap, the water running thru the opening l8 and openings 9.

In the scraping operation, the edges IQ of the blades designated by the numeral 3, are the effective operating surfaces of the device. These edges may be made semi-sharp and in fact sufficiently dull so as not to scratch the skin or surface of the hand, these edges may be rounded 01f or slightly bevelled yet not sharp enough to cut the skin but merely to provide the best type of scraping action.

Altho I have shown herein a preferred embodiment and structure of my invention, and inasmuch as it may be susceptible of many alterations, modifications, and improvements, I reserve the right to all such modifications, alterations, and improvements, as may come within the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

A device of the character described comprising, a hollow box-like structure provided with a four-sided arcuate top surface having a multiplicity of flexible scraper portions extended perpendicularly to an imaginary tangent drawn at the point where said scraper portions emanate from the said top arcuate surface, the said scraper portions being of a height slightly less than the space between them, their top corners being substantially arcuate, the said top arcuate surface provided with openings configurative to the shape of the said scraper blade portions, the base of each of said openings being located adjacent to the base-of each of said scraper portions, and four side portions substantially perpendicular to the said arcuate surface and bent in a direction opposed to that of the said scraper blade portions, two of the said side portions being suitably knurled to provide substantial gripping means.
