renin.. f (ci. exi-1150i This invention relates drying the film or print ata-nd adjacent the"l place whereit isgripped andthel'd. Previously?, wifthvthe uconstructions of my earlier patents",lthe drying of the nlm ormprints over `their entire surfaces, except atiiiadjiceritthe"places where held and suspended was very effectively accomplishedjf.

but" there were wet spdtsilet atw'such placsfof suspension, there not being permitted an effective drainage of water cr other fluid in which the prints or lrns had been immersed and washed, but drops of the liquid were held against passing downwardly over the surfaces of the photographic films or prints, resulting in either defective drying at the places on the lms or prints stated, or the necessity of a much longer time for complete and proper drying. In the present invention, such collection of moisture is eliminated by a very simple, practical and eiective improvement in construction, an understanding of which may be had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view of the clip of my invention having the improvement applied thereto in its open position.

Figs. 2 and 3 are, respectively, opposite side elevations of the clip.

Fig. 4 is an edge elevation, with parts broken away and in section, showing the clip in its closed operative position.

Fig. 5 is a similar side elevation with the clip open.

Figs. 6 and 'l are, respectively, under plan views of the clip in closed and open positions.

Fig. 8 is a fragmentary elevation and partial section of one side of the clip in a somewhat modified form, and,

Fig. 9 is an under plan thereof.

Like reference characters refer to like parts in the different figures of the drawing.

The clip, which is made of a thin metal of a resilient or spring nature includes two side I and 2 integrally connected at their upper edges by a band 3. A hook `llior suspending the clip vertically is struck from the upper portion of one side, such as the side 2, and the other side I may to" mis; and isprimaruy. concerned with a novel improvement,.partic'ularly` 'usedirrphoto-` Btisfprovidedito receive the `projection I whenithe sides-o :the fclip have been fforced `toward -,eac-hl have an ifopening :5 `made the elyipeponr;` a nail` jor` similarisupporta i oliromfone ofthe sides,- such as theside its lower end, metalsl-iscut to provide an opening 8 'leaving "at Athe loweri edge thereof an upwardly extending `projection1.` Fromthe other iside La" relatively Vwide and long-` tongue of metal ilis struck` jand bent 1 towardg the opposite side,r y and f curves iupwardl'y.at l its `f-ree endbeing adapted i to i pass Itl-iellfreetend through the openingv 6,when the v two sidesflandf 2r oi'V the clipare .pressed toward eachother into substantial parallelism,` asgshown;infll-ig;y 4t 11n thetongue Biianopening oth fw holding them-inftheir substantiallyparallel` closed position. Normally the sides I and 2 will spring apart at their lower end portions, the resil iency of the metal permitting closure and causing such opening or separation thereof at their lower portions upon releasing the tongue 8 from the projection 1 by pressing upwardly against the lower side of the outer end portion of the tongue. The structure thus far described is substantially like that shown in the rst of the above mentioned patents.

At the lower end of one of the sides, for example, the side 2, the metal is curved outwardly and back to form a transverse bead I0, at the free edge of which and substantially midway between its ends, a sharp projection II is located. Similarly the other side I is pressed outwardly into a transverse bead I2, which at its lower edge, terminates in a downwardly extending flange I3.

- Said flange I3, substantially midway between its ends, is formed with two spaced apart tongues I4 extending toward the projection I I approximately at right angles to the flange I3, and the bead I2 for a distance outwardly between said tongues is cut away to provide a slot I5. The tongues I4 are located relative to the projection II such that when the sides I and 2 are pressed toward each other and releasably locked in the position, shown in Figs. 4 and 6, said projection comes between the tongues I4 and the edges of the tongues bear against the adjacent edge portion of the bead IU from which the projection II extends. i

A wet nlm or print having its upper edge portion inserted between the lower edge of the bead Il) and the downwardly extending ange I3, with the clip open in the position shown in Fig. 5, will beengaged and held, when the clip is closed to the position shown in Fig. 4, by the projection II penetrating the film or print and with said ltherethroughrior hanging i film or print at each side of the projection gripped between the generally vertical edges of the tongues I4 and the adjacent lower edge of the bead I2 at each side of said projection II,

With such construction, there is no place for water or other liquid to collect and be retained on the surface of the lm or print. It will flow down by gravity over the sides of said film or print, and drying thereof is greatly facilitated in the matter of the time required toproperly dry the lm or print over all of its surfaces.

In Figs. 8 and 9 a slight modification in structure is shown. The side I is not formed with the bead I2 but extends downwardly in the same plane, tongues I4 being struck at the lower end portion of the side I to extend toward the projection II. The elimination of the bead I2 does not materially or in any sense seriously impair the invention so far as the accomplishment of drainage and drying is concerned and such bead I2, where used, is of relatively minor importance except for symmetry in appearance of the clip, and for a somewhat more free circulation of air at the side of the lm or print against which the edges of the tongues I4 engage.

`The present invention is very practical, useful and successful. Not onlyv is there a substantially complete elimination of collection and holding of small quantities of water at the points of engagement of the holding portion of the clip with the lm or print suspended therefrom, but a full 'freedom of air circulation at the lower end portions of the clip is insured, Such circulation of air enhances the speed of drying. While the invention has been described as being of great utility in connection with the drying of photographic lms or prints, it is to be undernr uv) stood that it has utility in many other relations for the holding of papers or the like of many kinds, either wet or dry.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

A clip comprising two sides adapted to be suspended in a generally vertical position and connected at their upper ends, said sides normally springing apart at their lower ends, means for releasably holding said sides with their lower ends brought closer together, the lower end portion of one of said sides having a transverse horizontal bead at the free lower edge of which, and between its ends, a pointed projection extends toward the other side, said other side at its lower end portion having two spaced apart tongues lying in vertical planes approximately perpendicular to the plane of said side, said tongues when the two sides are held against separation at their lower ends being located one at each side of said pointed projection.
