8 Claims. (Cl. 24F-259) UNlraD-s -TATES PATENT oFFlcr-zl Heretofore in clips for holding photographic nims one of the jaws of the clip has been provided with tubular bosses andthe otherwith pointed barbs which enter the bosses and when gripping the nlm vbetween the jaws it has been necessary to exert pressure thereon to cause the clip to firmly grip the nlm to prevent its slipping, for -the reason that vthe barbs have all been of the same length.

In the present invention, however, this objection has been overcome by providing barbs or teeth of different lengths so that when the film is gripped between the jaws, the spring of the clip will cause the larger barbs to penetrate the nlm l5 ilrst and will be followed by the lengagement of the im by .the shorter barbs, thereby obviating the necessity of exerting pressure upon the clip. Heretofore another serious objection is present with the former clips in that the jaws themselves will form a pocket which will retain a small amount of water, with the result that after the nlm has become dry and the clips are opened to detach the nlm therefrom, the water retained between the jaws will run down upon the dried 2S nlm, which is very objectionable.

To overcome these objections and diiliculties .and to provide an improved film cllp of this character in which means are provided for preventing the slipping of the im and of the formation of the sharp projection, is one of the objects of the present invention.

A further object is to provide improved means whereby the clips may be placed upon a supporting line or wire without interfering with the otherclips that are suspended thereby, and at the same time obviate the necessity of Stringing the clips upon the line, which latter operation results in the objection that the films will be brought into contact by the sliding ci the clips along the sup- 49 porting line. l

To the attainment of these ends and the accomplishment of other new and'useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention, and in which 0 1 Figure 1 is a top plan view of a clip of this character constructed in accordance with the principles of this invention.

Figure 2 is a bottom plan view of the clip. Figure 3 is a front end elevation of the clip. 55 Figure 4 is an edge view oi the clip.

Figure 5 is a view similar to Figure?. with the jaws of the clip separated.

Figure 6 is a view taken on line 6 6, Figure 1 on an enlarged scale.

Figure 7 is aview similar to Figure 6 showing 5 another form of clip.

Referring more particularly to the drawing, the clip consists essentially of two body members IIl--II which may be formed separately -from each other and connected together as at I2, or l0 may be formed of a ,single piece of material bent .into shape. The forward portions of the jaws IIi-II are bent towards each other as at I2-I3 so that they will cross, and in the portion I2 of the member Il there is provided a slot I4 through 15 which the portion I2 of the member I l passes.

The extremity I! oi the portion I2 is bent forwardly into a substantially horizontal plane and is provided with a plurality of tubular conical bosses i6 laterally spaced from each other to 20 form recesses or spaces I1 therebetween.

The extremity of the portion I3 of the member Ii is bent 'forwardly as at i8 and then at substantially right angles to the portion I8, as at I9.

The edge of the portion I9 is provided with 25 teeth or barbs 20,' laterally spaced from each other and positioned so that when -the jaw members are closed they will enter the openings in the tubular bosses I8.

One of these teeth or barbs 20 is provided for 30 each of the conical projections IS.

The edge of the jawl I9 is also provided with teeth or barbs 2i' which are preferably of a greater length than the teeth or barbs 20 and arranged intermediate the latter so as to enter the 35 spaces Il between adjacent tubular bosses I6 to contact the jaw I5. With this arrangement it will be manifest that when a film is placed between the jaws when the iatter are held open against the resilient-action of the body members '40 Ill-II it will rest upon the apexes of the conical bosses i6.

When the jaws are released the spring tendency of the body portions Ill-II will cause the jaws to move into contact with the result `that theA 4" longer barbs or projections 2I will contact and grip the film 22 before the shorter barbs 2t cooperate with the tubular bosses to grip the film. The shorter barbs will force portions of the nlm into the bosses, as at 23, While the longer barbs or projections 2| which are intermediate the barbs or projections 20 will co-operate with the portion of the jaw iibetween the bosses to further grip the lm, as at 24 and at the same 55 time limit the movement of the jaws of the clip towards each other.

The barbs or projections 2! being of a length greater than the barbs or projections 2@ will initially force portions of the nlm into the spaces between the bosses IB before the barbs or projections 2b engage the nlm.

With this form of the invention it will be man1- fest that the iilin will not be perforated and the extent to which the barbs 20 and the bosses l5 grip the lm will be controlled by the barbs or projections 2i contacting the jaw i. The barbs or projections 20 may be of any desired coration.

In the end 25 ofthe body portion of the clip lthere is provided a slot or recess 2b which opens through the end thereof and this recess at its inner end is enlarged, as at 2l, to provide an overhanging and undercut lip 28 that is spaced a substantial distance from the entrance end of the slot.

This slot is provided for the purpose of stringing the clips upon a supporting wire or line to obviate the necessity of having to thread them thereupon. This latter operation results, when additional clips are threaded 'upon the line, in causing the lms to be moved into contact with each other which is not desirable.

With the present invention the clip can-be fastened upon the supporting line very readily by causing the line to enter the slot 26 into the seat 2l and then moving the clip so that the overhanging and undercut lip 28 will engage and rest upon the line.

In Figure 7 there is shown another form of the invention in which the jaw IS is provided with barbs 29-3@ that are pointed, the barbs 2a being` somewhat longer than the barbs 3G, each of the barbs 'being adapted to enter one of the conical bosses IS. The longer barbs 29 are preferably located between the shorter barbs 30. In this form of the invention the longer barbs 29 will penetrate the iilm 22 iirst to hold the film from slipping and the tendency of the spring of the body portion of the clip will be to subsequently cause the shorter barbs to penetrate the film.

It has been found that in clips of this charac- 'ter water accumulates between the jaw when the film is suspended by the clip with the result that after the film is dry and when the clip is opened the water will run down upon the dried ilm and spoil the same. By the provision of openings 3i in the jaw i9 water will be prevented from accumulating and will drain out through these openings.

While the preferred forms of the invention have been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of the invention.

What is claimed as new is:

3. A lrn clip embodying co-operating jaws, one of the jaws being' provided with laterally oilset tubularr bosses, the other jaw being provided with spaced projections adapted to enter the respective bosses, and means carried by one of said jaws and adapted to contact the other jaw for limiting the extent to which the said projection will enter said bosses, the said means embodying additional projections on the second recited jaw adapted to contact the other jaw outside of and intermediate said bosses.
