To all whom it may concern.-

Be it known that I, GEORGE W. MCGILL, a citizen of the United States, and aresident of Riverdale-on-I-Iudson, in the county of New York and State of New York, have invented certain new and useful Improvements in Spring Clips, of which the following is a specification.

My invention consists of a spring-clip fashioned from a wire blank consisting of a single piece of suitable spring-wire having bulbous-shaped terminals, the central part of such wire blank being folded into a trifoliate or clover-leaf configuration, with its free end parts providing a split stalk-like formation therewith, and having the strands of the wire forming the latter diverging from the folded center of the blank in manner to rest in spring-bearing longitudinally against the diverging wires in the opposite sides of the upper part of the loop forming the central or lower lobe or leaflet of the trifoliate or cloverleaf configuration of the body of the device and with the bulbous terminals of the ends of the blank providing its stalk-like formation projecting beyond the lower part of the same.

In the accompanying drawings, in which similar letters and numerals of reference indicate corresponding parts, Figurel is a horizontal side view of the wire blank from which the clip is fashioned. Fig. 2 shows the blank folded into the trifoliate or clover-leaf formation intended. Fig. 3 shows as a modification in its construction the opposite side of such formation with portions of the free ends of its blank curving inwardly toward each other. Fig. 4 shows the clip so fashioned applied in clipping papers together.

A is the body part of the wire blank, and a a are its bulbous-shaped terminals. The blank so fashioned is folded at its center into the lobe or leaflet formation 1 and is then further folded from the bends marked 4 4 on opposite sides of the lobe 1 around to the points 5 5, forming the lobes or leaflets marked 2 and 3, respectively, with its free end parts A A (which provide the leaf its stalk-like formation) diverging downward from the points 5 5 in manner to rest in spring-bearing at 6 against and longitudinally upon the under surface of the wire forming the upper part of the opposite sides of the lobe or leaflet 1, its bulbous-shaped terminals projecting below and beyond the lowest part of such lobe or leaflet 1. The bearingsurfaces of the clip may be lengthened by the inward curving of port-ions of its free ends, as shown in Fig. 3.

lhe clip is applied to the uses intended by pressing the edges ofthe papers B against the arms or stalk formation A A of the trefoil and under its lobe or leaflet 1 and up into its lobes or leaflets 2 and 3, where the papers are clasped and held by being pressed upon from opposite sides by the bearing-surfaces of the parts A A and the bearing-surfaces of the wire forming the opposite sides of the lobe or leaflet 1 at the parts marked 6 6, as shown in Fig. 2, said surfaces in their normal position being superimposed throughout their length in springbearing with each other, as shown in said Fig. 2.

The bulbous terminals of the wire blank from which the clip is formed prevent. all abrasion or tearing of the papers while being inserted or withdrawn from the clip, and being of greater diameter than the rest of the wire therein they press the clipped papers from behind against the lower surface or the lower lobe or leaflet of the trefoil of the clip, thereby aidingin clamping and securing them therein.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A spring-wire clip having the free end parts of the Wire constituting its clampingarms provided with bnlbous-shapedterminals.

2. A spring-clip made from a single wire blank of suitable length, gage and temper, folded at its center in manner to provide the clip a body part or frame, with the two end parts of the blank folded down from the upper part of such frame in manner to cross it on diverging lines and to bearlongitudinally for part of their length along and against correspondingly-diverging lengths of wire centrally located in the frame, with the terminals of the blank projecting below the base of the frame.

3. Aspring-clip fashionedfromawire blank of suitable length, gage and temper, folded at its center in manner to provide the clip a body part or frame of trifoliate configuration, with the two end parts of the blank depending from the inner sides of the upper lobes of the frame on diverging lines cross ing the latter and in their transit resting lengthwise in resilient spring-bearing along corresponding lengths of the wire forming the under lobe of the frame, with their free terminals extending below such lobe.

4. A spring-clip fashioned from a single wire blank having integral bulbous terminals and a. folded central part, the latter providing the clip a frame or body which is crossed on diverging lines by the unfolded free ends of the blank, which ends, in such transit across the frame, bear lengthwise against similarly-diverging lengths of the wire located centrally therein, the bulbous terminals of such ends projecting below and beyond the frame proper.

I 5. A spring-clip fashionedfrom a single wire blank of suitable length and diameter folded 20 at its center in'manuer to provide a frame or body part of trifoliate configuration, with the free ends of the wire diverging downward from the upper center of such frame and for part of their length in longitudinal spring- 25 GEORGE W.
