CLIP.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed March 14,1905. Serial No. 250,114.

ful Improvements in Clips, of which the fol-- lowing is a specification.

This invention relates to improvements in paper fasteners or clips, and among the several objects in view is the production of a' clip free from projecting points or overhanging portions destined to contact with foreign objects and dislocate the clip or cause the foreign objects to be bound up with the paper sheets or other articles held by the clip.

A further object is the provision of aclip which shall be free to expand to the required extent without danger of lateral separation of the ends of the clip.

With these and further objects in view the invention involves certain novel constructionsand arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a view in side elevation of a piece of material from which the preferred embodiment of the adapted to be made, the intermediate bend being shown. Fig. 2 represents a View in side elevation of the preferred embodiment of the invention, the clip being seen applied to a sheet of paper or other article. Fig. 3 represents a similar view of the same with the paper omitted. Fig. 4 represents an edge view thereof, illustrating the relation of the two coils. Fig. 5 represents a similar view thereof, illustrating the intermediate bend and its relation to the ends of the rod from which the clip is formed. Fig. 6 represents a detail fragmentary view of the same, the parts being seen on an enlarged scale. Fig. '7 represents a perspective View of the clip. Fig. '8 represents a View similar to Fig. 1 of a blank for a modified form of clip. Fig. 9 represents a fragmentary edge view of the said modification. Fig. 10 represents a view in side elevation of a further modification.

In paper-clips as heretofore constructed it is to be noted that projecting ends or shoulders are usually found, which are objectionable for the above-mentioned reason, and, further, many of the well-known clips are so constructed that a twisting strain is liable to separate the arms of the clip to such 's aclng member,

present improved clip is an extent as to render the same useless, and in order to provide a simple, cheap, and durable clip which may be formed from a spring-rod of the ordinary type, which clip shall have'no projecting points and which shall not be liable to become useless from. a

slight twisting strain, I propose to embody the invention disclosed in the accompanying drawings into a practical structure by employing the elements illustrated in said drawings, in which- 1' indicates a bar or rod of suitable spring material, which is bent intermediate its length, as at 2, into .a connecting portion or s arp angles. Each of the portions of the rod 1, extending from the'connecting portion or spacing member 2, is formed into a loop, and the end 3 extends beneath the respective overhanging portion of the bend 2, so that in operation when a sheet or sheets of paper are passed between the two loo s, so that each of the ends 3 is forced away om its respective contiguous portion of the rod 1, such end 3 will contact with the overhanging portion of the bend 2, and thus be prevented from unduly spreading, whereby injurious twisting strain is largely obviated, the said bend or connecting member 2 thus constituting a stop for the ends 3 and limiting the amount of movement thereof. The bar 1 is thus formed into two loops, which, of course,

may be of any size; but, by preference, I make one of the loops larger than the other, and, as will be best seen in Fig. 4, the smaller loop is preferably depressed at its outer free edge into the larger loop, whereby separation of the loops can be accomplished only against spring-pressure, the clip being designed to be applied to a sheet after the manner illustrated in Fig. 2, wherein the sheet or sheets has or have been passed between the two loops and is or are clamped between the same. Considering the construction of the clip from another view-point the same may be said to be a two-spiral conical spring, the lesser spiral being depressed at one point into the greater and being spaced from the greater at another point. At the point where the spirals are spaced a art the edges of the spirals are connected y member 2, and it is preferably at the point of the diametrically opposite edges 2 2 of the spirals that the lesser spiral is depressedinto the greater.
