Application filed August 19, 1927. Serial No. 214,155.

This invention relates to improvements in spring clips.

An object of the invention is to provide a clip for temporarily securing together a large number of articles, as leather, cloth and articles of other like material. The present construction of spring clip has been found to be very useful in firmly securing or holding together pieces of leather for articles that are in the course of manufacture, as for example in the boot and shoe industry.

One of the purposes of the spring clip is to provide a device which will exert a firm pressure substantially along a straight line, or, in other words, the frictional resistance is applied on a very small surface of the material that is being clamped, with the result that a stack of leather, paper, or other like material is firmly secured'against displacement when the pile of leather, rubber cloth, or paper is undergoing the cutting, sewing, or other operation. Heretofore, spring clips have been devised in which long or extend ed clamping or pinching surfaces are employed. This form of clip has been found to be inefficient for the reason that the frictional resistance is distributed over a too large surface. The present spring clip is designed to effectively remove this objectionable feature.

The present spring clip comprises, in general, two spring arms that are normally in contact with each other. This normal posi tion of the spring arms is brought about by forming the clip from one piece of sheet steel that is highly tempered, the arms of Which are connected by forming the material into substantially an angular shaped loop, the

sides of which have imparted thereto a set which always operates to cause the arms to move towards each other. One of the arms is made very much shorter than the other with an upturned curved end of short radius. This short arm normally rests upon the other or longer arm. By means of this construction a very efficient spring clip construction is provided.

Further objects and nature of the inven tion will be set forth in the body of the description with reference to the drawings and specifically pointed out in the claim.

Referring to the drawings:

Fig. 1 is a perspective view of the spring nates the apex portion of the loop. The arm 2 is formed at its lower end with an upwardly extending curve 7 of short radius, the

lower part 8 of this curved portion normally rests directly upon the upper surface-of the arm 1 as shown in Fig. .1.

As shown in Fig. 2 in use, the layers of material 9 that are being clamped are inserted between the two arms. The sharply curved part 7 rests directly upon the upper surface of the'pile of material. It will be observed that this curved part of the arm 2 at its point of contact 8 forms'depressions in the layers of the material being clamped, as indicated at 10, in other words sure of the arm 2 is transmitted downwardly through all of the layers to the upper surface of the arm 1, as indicated by the line 11. 'The point of contact is therefore confined to a single transverse line by means of the small point of contact 8, of the curved portion 7 of the arm 2. The material is, therefore, held Very firmly against lateral or sliding movement between the arms. It is of course obvious that the greater distance that the arms are separated the greater the pre'ssureexertedon the material.

The upwardly curved end 7 permits the material to be readily inserted between the arms.

It is to be understood that I do not limit myself to the exact dimensions shown, but it is to be understood that the broad idea of utilizing in a spring clip. having twoclamp ing arms with one arm shorter than the other and formed with an upwardly curved end of small radius which normally engages the other arm is new as far as I am aware.

The advantages of the present spring clip among others, are that layers of leather orcloth may be firmly held in place by gripping them at oneline of contact, also, they the pres may be readilyinserted and; removed. The curve of such a radiusesto exert downward 10 loop 3 permits the arms being separated a pressure along a. single line of contact only wide distance. on the material which is inserted between What I- claim is: the arms, the inwardly set" connecting loop 5 Aspringclipcomprising an integral mam of. the arms operating for permitting the her having two arms of unequal length and arms to be separated. avsubtltmnh Hilly W e 15 connected by a loop portion with inwarddistance. 1y set sides, the shorter arm being curved sharply upward at its end and formed on a I WALLACE L.
