CLOTHES PIN. APPLKZATION FILED MAY 23. 1917.

FRANK NORRIS, OF BARNUM, WISCONSIN.
Specification of Letters Patent.
Patented Mar. 12, 1918.
. Application filed May 28, 1917. Serial No. 170,486.
To all whom it may concern:
Be it known that I, FRANK NORRIS, a citizen of the United States, residing at Barnum, in-the county of Crawford, State of Wisconsin, have invented certain new and useful Improvements in Clothes-Pins; and
I 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 economy of manufacture.
In the drawings Figure 1 is a perspective view of the device I Fig. 2 is a longitudinal section, and Fig. 3 is a plan view looking into one of the pin members.
Referring more particularly to the drawings, land 2 represent respectively, the complementary jaws of the pin, which are mounted upon a spindle 3 and are held in normally closed osition by a spring 4.
Each of the aws 1 and 2 consists of a sheet metal unit formed from a substantially rectangular blank, the edges of the blank being turned upwardly at right angles to the body thereof from one end to a point slightly beyond the middle, the upturned portion 5 inclining from the end upwardly to the middle point, and the points of maximum rise providing the bearing whereby the jaws are mounted on relative rocking relation upon the spindle 3. Beyond the spindle 3 the vertical wall portions 5 are gradually inturned, as at 6, the gripping ends of the jaws being thus reinforced and strengthened. If desired, the blanks be rolled inwardly along their forward ends, to provide the beads 7 before the lateral edges are inturned, whereby perfectly smooth and rigid lips are provided on the free ends of the jaws.
After the jaws have been formed as above may described, they are interlockingly grooved or corrugated, so as to provide perfect gripping contact of the jaws upon a line and upon the clothes supported thereon. Also, the handle ends of the jaws may be transversely and outwardly punched or corrugated in order to provide perfect grip for the fingers.
Before the jaws 1 and 2 are mounted upon the spindle, 3, the spring 4 is placed upon the spindle, the spring consisting of a coin tinuous spring wire element doubled upon itself having the intermediate portion of the legs thereof coiled around the spindle and then carried into position opposite the double portion, so that the double portion and the free ends of the legs expand through the inherent resiliency of the spring to close the aws.
From the foregoing description, it will. be apparent that I have provided a very practical. and eificient device used as a clothes pin, a new article of manufacture constitutiiig a desirable substitute for the usual wooden clothes pin.
What I claim as my invention is A clothes pin, comprising in combination, a pair of metal jaws and each consisting of a body portion having marginal initial upstanding walls having a maximum height at the middle point of the body, and said marginal upstanding walls being folded inwardly into contact with the body portions beyond said middle point to provide contacting jaw portions, a spindle connecting said jaws at the point of maximum rise so that they will rock relatively to one another, and a spring mounted upon the spindle and normally throwing the jaws into closed post tion, the contacting jaw portions having cooperating corrugations extending trans versely thereacross.
In testimony whereof, I affix my signature in the presence of two witnesses.
Witnesses WM. ALDERMAN, L. S. HASKINB.
