P. GAMPHER SCRAPER FOR wALKs Filed Oct. 31 1923.

UNITED STATES PAUL GAMPHER, OF CHICAGO, ILLINOIS.

scnnrna FOR wALKs.

Application filed 0ct0ber31, 1923. Serial No. 671,833.

To all whom it may concern:

Be it known that I, PAUL GAMPHER. a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Scrapers for I'Valks, of

which the following is a specification.

The object of my invention is to produce a scraper that is especially adapted to clean sidewalks of mud, water, snow, slush and ice in the most eiiicient manner and I accomplish this by the peculiar shape and construction of my scraper.

Reference will be had to the accompanying drawings in which Fig. 1 is an elevation of the scraper looking sidewise in the position of the scraper when normally in use.

Fig. 2 is a similar position to that of Fig. 1, but with the working blades reversed.

Fig. 3 is a view looking in the direction of the arrows 3-3 in Fig. 2.

Fig. 1 is a sectional view on line 41 of Fig. 2.

Fig. 5 is a view of the scraper when the same is set at repose with the handle up right.

In the drawing, 1 indicates an ordinary round wooden handle, which is secured into a socket 2, and riveted thereon by the rivet 3. The socket '2 is provided with arms 1, 5, 6, and 7 secured by rivets 8 to the scraper blade 9. This blade 9 has a curved body in dicated by 10 in Fig. 1, and provided with a broad working edge 11 and a narrower reverse edge 12 located in the middle portion of the body of the blade.

In the use of a scraper of this kind it frequently occurs that the workman is called upon to arrest the scraping operations, and to do something else such as brooming off the walk or shoveling the material into carts or wagons, for removal, and it is a conven ience and a labor saving feature to be able to stand the scraper up directly in an upright position so that it will stand alone without being required to drop on the walk or he leaned up against a building when not in use. In order to serve this purpose I so fix the handle of my scraper as indicated in Fig. 5 that it will assume a position of stable repose upright on the walk 13 as shown in Fig. 5.

With other scrapers of the similar type to this, they will not stand with. the handle upright in a position of repose, and therefore every time the operator releases his control of the scraper he is compelled to let it drop on the walk or let it lean up against something and in doing this he loses a lot of time.

The men who handle scrapers of this kind are generally janitors who are interrupted in the work of scraping for numerous other services and thus time and inconvenience is occasioned by not having the scraper that will stand alone as it were on the walk but I provide my scraper to give such service.

In the normal use of the scraper on soft material the long blade 11 will usually be used, but in the case where ice, dirt and other material that may adhere strongly to the walk is required to be removed then the narrow blade 12 will be the most serviceable.

By making this narrow blade 12 substantially in the middle and directly in the center line of thrust it may be used somewhat as a chopping tool as an ax might be used or other impact member in freeing ice or other material from the walk.

The arms 4, 5, 6, and 7 are reinforced by the ribs 141 thus making a very strong connection and yet a light one for the socket 2 to the blade 9.

The alignment of the handle is offset or set asunder from the body of the blade a little to the left or nearer to the cutting edge 12 as best observed in Fig. 5, for the pur pose of arriving at a desirable angle for the cutting edge 12 when the same is used as a chopping tool in the form shown in Fig. 2 which is a desideratum.

What I claim is 1. In a scraper of the class described, a blade curved in outline and having a cutting edge on the upper and lower sides, and one of these edges being narrower than the other.

2. In a device of the class described, a curved scraper blade having a long cutting edge on one side and a shorter edge on the other side, and the shorter edge located in the middle section of the body of the scraper as relates to the length of the blade.

3. In a device of the class described, adouble edged curved blade, secured to a handle approximately at right angles to a line drawn between the cutting edges in a manner that the handle will stand upright with both cutting edges resting on the walk.

4. In a scraper of the class described, a

curved blade having two cutting edges and with a handle mounted substantially at right angles to a line drawn between the cutting edges and this handle set slightly asunder from what might be termed the vertical center line between the cutting edges of the blade.

5. In a device of the class described, a curved blade having a long cutting edge on one edge and a shorter one on the opposite edge with a socket for a handle connected to the blade having four arms in cruciform arrangement and secured to the blade and with a handle suitably mounted in the socket.

6. In a device of the class described, a

curved blade having a broad cutting edge on one side and a centrally located shorter edge on the other side and provided with a socket secured to the blade thru the medium of cruciform arms, the shorter arm being located in the region of the shorter cutting edge and with a suitable handle mounted in the socket.

Signed at Chicago, in the county of Cook and State of Illinois, this 11th day of October, 1923.

PAUL GAMPHER.
