FILM CLIP Filed M-af 1927 Patented Jan. 31, 1928.

UNITED STATES PHILIP J. KIR-WAN, OF GLENWOOD SPRINGS, COLORADO.

FILM

Application filed May 14,

This invention relates to film clips and has for an important object thereof the provision of a device of this character which may be very readily and cheaply produced and which will securely hold the ends of a roll of film out of contact with one another.

A further object of the invention is to provide a device of this character which may be readily COHSUUCQQCl from a single piece of metal and which accordingly embodies no portions which may become displaced.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation showing a clip constructed in accordance with my invention applied to a film;

Figure 2 is a side elevation of the clip;

Figure 3 is a vertical sectional view through the clip on the line 33 of Figure 2 showing the clip compressed in preparation for engagement with the ends of a film;

Figure at is a section on the line 4-4.- of Figure 2;

Figure 5 is a plan of the blank from which the clip is formed.

Referring now more particularly to the drawings, the clip comprises a body formed from a spring sheet and bent in substantially U form. The arms of the clip, designated at 10, have each struck-out theref om a plurality of tangs 11, the tangs of each arm being staggered with relation to the tangs of the other arm. Each arm is further formed with openings 12, which align with the tangs of the other arm and through which the tangs of the other arm are directed. Each tang has its end portion reverted in spaced relation to the body of the tang and turned inwardly to confront the outer face of the arm through an opening of which it is directed, as indicated at 13, beneath said opening. Beneath each of its openings. each arm is formed with small openings 14, in the production of which, has the metal about its edges swedged outwardly, as indicated at 15, to form tapering tubular bosses. The ends of the reverts 13 are pointed and adapted to extend into these openings 14. Each arm of the clip adjacent the connection 16 therebetween is preferably formed with an opening 17 for the reception of a supporting element whereby the clip may be supported. The body from which CLIP.

1927. Serial No. 191,388.

the clip is formed is preferably narrowed at its central portion, as indicated at 18, so as to make this central portion of the clip of size such that it may be conveniently grasped while le ring relatively broad film confronting faces at the ends of the arms.

It will be obvious that a device of this character may be very readily and cheaply produced and is readily manipulated. Since it is formed from a single piece of metal, there are no crevices provided for the collection of acids used in photographic work, which would tend to cause the clip to deteriorate rapidly.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim 1. A clip comprising a flat sheet of spring metal bent into substantially U-form, each arm having struck inwardly from the inner face thereof a tang, the tangs of said arms being offset with relation to one another, each arm having an opening for the passage of the tang of the other arm, each tang having its free end reverted and confronting the metal of the arm through the opening of which it passes.

2. A clip comprising a flat sheet of spring metal bent into substantially U-form, each arm having struck inwardly from the inner face thereof a tang, the tangs of said arms being offset with relation to one another, each arm having an opening for the passage of the tang of the other arm, each tang having its free end reverted and confronting the metal of the arm through the opening of which it passes, the end of the reverted portion being pointed, each arm having a further opening confronting the pointed end of the reverted portion and into which said pointed end may extend.

3. A clip comprising a flat sheet of spring metal bent into substantially U-form, each arm having struck inwardly from the inner face thereof a tang, the tangs of said arms being ofiset with relation to one another, each arm having an opening for the passage of the tang of the other arm, each tang having its free end reverted and confronting the metal of the arm through the opening of which it passes, the end of the reverted portion being pointed, each arm having V a further opening confronting the and bent pointed end of the reverted portion and into which said pointed end may extend, the metal about the last named openings being swedged outwardly to provide tapered bosses 5. A film clip comprising a length of spring material having relatively broad ends and bent into U-form, each arm of the U having struck-out therefrom inwardly directed tangs the tangs' of each arm being offset with relation to the tangs of the other arm, each armhaving an opening for the passage of the t-angs of the other arm, each tang having its free end reverted in spaced relation to the body. thereof and pointed, each varm being further provided with openings into which the pointed ends of the tongs of the other arm may extendp V In testimony whereof I hereunto affix my si gnature.
