SPECIFICATION forming part of Letters Patent No. 752,185, dated February 16, 1904. i

- Application filed April 13, 1903. Serial No. 152,377. (No model.)

To all whom it may concern:

Be it known that I, EDWARD L. SIBLEY, a citizen of the United States, residing at Bennington in the county of Bennington and State of Vermont, have invented a certain new and useful Improvement in Paper-Clips, of which the following is afull, clear, and exact description.

This invention relates to that class of spring devices used for temporarily connecting sheets of paper, fabric, and other objects and variously known as paper-clips or paper-fasteners.

The object of the invention is the production of an efiicient metal paper-clip without waste of metal or with a small waste.

The invention consists of a many-armed metal piece bent upon itself to bring its arms in opposition and whereby the elasticity of the metal is utilized to grip between the arms the object or objects to which the clip is applied, the arms being offset from a transverse connecting member, all as I will proceed now more particularly to set forth and claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view showing one method of forming the blanks without Waste. Fig. 2 is a plan view of one of the blanks of Fig. l, and Fig. 3 is a perspective view of the finished clip formed from the blank of Fig.2. Fig. 4 is a plan view illustrating another method of forming the blanks without waste. Fig. 5 is a plan view of the blank of Fig. 4, and Fig. 6 is a perspective view of the finished clip formed from the blank of Fig. 5.

Referring to Figs. 1 to 3 and also to Figs. 4: to 6, it will be seen that the devices are blanked out of a strip of metal, as shown in Figs. 1 and 4:, without waste, alternate blanks being shown in black and white the more clearly to indicate the lines of out. Spring metal, such as brass, is preferably used. In these forms four arms are used, and in Figs. 1 to 3 the arms 1 and 2 are ofiset from atransverse connecting member 3, which extends obliquely of the arms, while in Figs. 4 to 6 the arms 4 and 5 are olfset from a transverse connecting member 6, which extends at right angles to the arms. The blank, Fig. 2, has its arms 1 bent over upon the arms 2, so that their ends lap over upon them, and this is possible by reason of the obliquity of the connecting member 3. The arms 2 therefore form a base against which the arms 1 may I grip an object. The blank of Fig. 5 hasits arms 4 bent over arms 5, but because the connecting member 6 is at right angles to the arms the arms will alternate, and while parallel or in opposition they are not superposed, as in Fig. 3. If the blank of Fig. 5 be folded on a line running obliquely across the connecting member 6, then the clip will have overlapping arms, as in Fig. 3. In all of the forms of clip the folding is such as to leave more or less of a loop adjacentthe connecting member, and the arms shown uppermost in Figs. 3 and 6 are bent toward the arms shown beneath in said views, so that the clips may have the necessary resilience and gripping power, and the ends of the uppermost arms are reversely curved, so as to facilitate theapplication of the clips to an object. A characteristic of all of these forms of clips is that their arms are parallel, or substantially so, in the plane where the actual gripping is effected.

While I have particularlyshown and described these various embodiments of my invention, I wish it to be understood that it is susceptible of other variations.

What I claim is 1. A paper-clip, composed of arms and a transverse connecting member arranged 0bliquely with relation to said arms.

2. A paper-clip, having offset arms and a transverse connecting member.

3. A paper-clip, having offset arms and a transverse connecting member arranged obliquely to said arms.

4. A paper-clip, having ofl'set arms anda transverse connecting member arranged obliquely to said arms, said arms folded over and in contact at their gripping plane.

5. A paper-clip, composed of a piece of metal folded upon itself, and having a number of arms arranged to come in opposition and In testimony Whereof Ihave hereunto set my (gfl SQDfEOID and connected by atransgerse menghand this 11th day of April, A. D. 1903.
