Specification of Letters Patent.
Patented Mar. 28, 1911.
Application filed February 28, 1910. Serial No. 546,450.
To all whom it may concern:
Be it known that I, JOHN C. OLIVA, a citizen of the United States, residing at Marengo, in the county of Iowa and State of Iowa, have invented a certain new and useful Shoe-Scraping Device, of which the following is a specification.
lhe object of my invention is to provide a shoe scraping device of simple, durable and inexpensive construction that may be formed complete of a single piece of material and that may readily and easily be driven into the ground and that is provided with means for limiting the downward movement of the scraper into the ground and that is also strongly and firmly braced and reinforced.
A further object is to provide a device of this kind that may be formed complete of a single piece of sheet metal in such a manner that the metal will have a double thickness throughout the entire device and also in such a manner that it is strengthened and reinforced at the various points where the greatest strain or weight occurs.
My invention consists in certain details in the construction of the shoe scraper whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:
Figure 1 shows a front elevation of a device embodying my invention made of cast metal. Fig. 2 shows a side elevation of same. Fig. 3 shows a view similar to Fig. 1 illustrating a device embodying my invention made of a single piece of sheet metal. Fig. 4 shows a side elevation of same, and Fig. 5 shows a plan View of a blank piece of sheet metal cut out as required to form my improved shoe scraper. The dotted lines in said figure show the lines along which the sheet metal is folded.
Referring to the accompanying drawings, the head of the device is indicated by the numeral 10. Its top central portion is preferably fiat at 11 to form a scraper for the sole of a shoe. At the sides of the part 11 are the upwardly extended lugs 12 which preferably extend inwardly at their upper ends toward the center of the part 11 for the purpose of scraping a shoe above the sole. At the bottom of the head 10 is a flange 13 arranged in a substantially horizontal position and below the flange 13 is the body portion 14 which is preferably tapered to a point at its lower end. On one side of the body portion lt is a reinforcing rib 15 also tapered to a point at its lower end, the upper end of said rib being formed integral with the flange 13.
In the form of the invention shown in Figs. 1 and 2, there is also a rib 16 extending through the flange 13 to the central portion of the part 10 to strengthen and reinforce the rib and the part 10.
In the form of my invention which is made complete of a single piece of sheet metal the blank for forming the shoe scraper is cut out in the manner shown in Fig. 5. In this form of my invention the part above ground comprises a body portion 17 provided with an opening 18 so arranged that when folded along the dotted lines 19, there will be a double thickness of the parts corresponding to the part 10 as shown in Fig. 1. Furthermore at one end of the part 17 is an extension 20 having a slot 21 and two side flaps 22, and in the opening 1.? is a side reinforcing flap 28 for purposes hereinafter made clear. The part of the device to be inserted below the ground comprises a body portion 2-1 tapered to a point at its lower end. In folding the part- 24, I first bend the sides thereof along the lines 25 to form a double thickness of material and I then bend it alongthe lines 26 so that the remaining parts outside of said lines 26 constitute ribs or flanges 27. At the upper ends of the ribs or flanges 27 are the lugs 28 which are so arranged as to fold along the lines 29 upwardly and toward the body portion of the device above ground and said parts 28 constitute the flanges for limiting the down ward movement of the device into the ground. After the parts that go below the ground have been folded then the head of the device is doubled along the line 19 and the slot 20 will receive the upper end of the reinforcing ribs 27 to hold them together and then the flanges 22 are folded over back of the scraper to firmly hold the parts together. Then the part 23 is folded over the flat surface which constitutes the portion of the foot scraper that receives the sole of the shoe to thereby strengthen and reinforce the device at this point where the greatest wear takes place. It also prevents the two parts of the head from spreading away from each other so that on account of the peculiar construction and arrangement of the sheet metal portions, the entire device may be made of a single piece of sheet metal and there is not only a double thickness throughout the entire device but in addition to this the parts are all strengthened and reinforced where it is necessary to hold them together to make a firm, strong and durable device out of a single piece of comparatively thin sheetmetal.
In the form of theinvention shown in Fig. 3, I have provided at the top of the scraper the outward projecting lugs which may be usedin scraping mud from a shoe and I have also rounded the body portion of the scraper at 31 for convenience in scraping shoes.
It is obvious that with either form of my improved scraper the device may be readily and easily driven into the ground and its downward movement into the ground would be limited by the flange. It will be firmly and securely held in its position in the ground on account of the shape of the part flange being designed to limit the downward movement of the device in the ground.
2. In a device of the class described, a single piece of sheet metal comprising a body portion tapered to a point at its lower end and having its sides doubled over adjacent to each other at the longitudinal center of the device and having its side edge portion projected away from the body portion and parallel with each other, lugs at the upper ends of said side edges extended toward the body portion of the device and outwardly away from each other to form a flange to limitthe downward movement of the device into the ground, the head of the scraper being doubled along a horizontal line and folded over, said folded over part being provided with an extension having a slot therein to receive the projecting edges of the lower portion of the device and also having lugs at its sides folded over the back of the body portion of the device to firmly unite said parts, said folded over portion of the top of the device being also provided with a flange folded over the top edge of both por tions of the upper part of the device to form a rounded straight edge for scraping purposes and to strengthen and reinforce the scraper at the top.
