PATENT JOHN SOHMID, OF OLNEY, ILLINOIS.

CLOTHES-PIN.

SPECIFICATION forming part of Letters Patent No. 446,648, dated February 1'7', 1891.

Serial No. 317,427. (Na model.)

To ctZZ witam, it may conccrn:

le it known that I, JOHN SCHMID,a citizen of the United States, residing at Olney, in the county of Richland and State of Illinois, have invented certain new and useful Improvements in Clothes-Pins,of which the following' is a specification.

Myinvention relates to that class of elothespins in which two elamps forming` javvs are pivotally held together by Springs so that they may be opened or spread apart to receive the clothes-line and automatically closed to engage said line and the clothes hung upon it, all of which will be fully hereinafter Cleseribed, and particnlarly"pointed out in the clail'ns.

In the aceonlpanying drawings, Figure l is a longitudinal elevation of niy improved clothes-pin; Fig. 2, a plan of the same; Fig. 3, a longitudinal section on line a; of Fig. 2; Fig. 4, a detail perspective view of one of the divisions or clamp-bars forming part of my Clothes-pin, and Fig. 5 a detail perspective view of my improved form of coupling-spring for pivotally holding the two clanip bars together under pressure.

A A' represent two clanufiing-bars, each being a counterpart of the other and constructed asV I shall now describe.

a a are transverse grooves cut in the outer plane faces of the clamps near their forward ends, and b b shallow transverse grooves cut in the inner engaging faees orfulcrum-points of said clamps intermediate their ends.

a' 0/ representinwardly-disposed bevels on the forward ends of-the clamps, furnishing a inouth to receive and guide the clothes and 'line to be `gripped within the opening formed posed (in detail) of a single length of suitablytempered or resilient wire formed centrally with a plain straight cross-bar orligament (l, two circular springs or coils D D,one at either end, said cross-bar at right angles thereto, and tangential arms dd, which latter are immediate continuations or extensions of said coils and have but a single right-angled bend in each of them. lVhen the several parts are in proper position for use, the cross-bar or ligament O whose principal and preferred function is to unite the coils D D lies within the grooves Z) of the clamp-bars, said coils being parallel with and abutting against the opposite sides of both bars, and the inwardly disposed ends of arms (Z (Z engage the grooves a a cut in the outer plane faees of said bars, all as very elearly shown in the several views of the drawings.

The operation of the elamps ou the clothes and line is as customary, and will therefore 'need no description here. It will he seen,

however, in said operation that the large vertical cireular springs which extend from edge to edge of both sides of the clamp-bars and ahut against the same at all points will effectually hold the said bars against torsional and transverse inovement or disengagement, and also that the thin and straight central cross-bar or ligamcnt O forms a stationary shaft or bearing upon which the clamp-bars may turn with but little if any friction or wear.

I. clain1- 1. In a elothes-pin, the combination, with two fiat clamping-bars fulcrumed at a point intermediate their ends, of a coupling and pressure device consistin g of aA single piece of wire having a straight central portion of the same length as the width of the bars and having its ends bent at right angles thereto and each formed into a circular spring of a diameter substantially the same as the thiekness of the pin and having the straight portion for a center, the portion of the Wire beyond said springs being extended at a tangent thereto, and each portion having its end bent inward and engaging with the outer surface of the bars parallel with the straight portion, substantially as deseribed.

2. Acoupling and pressure device for unit IOO having its end bent inwardly parallel with the other and With the straight central portion to engage with the outer surface of the bars, substantially as deseribed.

In testimonyof which invention I have hereunto set lny hand.

JOHN SCHMID.
