To all whom ttmay concern:

B e it known that I, Louis SCHLESINGER, -a' citlzen' ofthe United States of America,

residing at 1130 Unionavenue, New York c1ty, 1n the county and State of New York, have invented certain new anduseful Improvementsin Flash-Pans, of which the following is a specification.

lMy invention relates'to flash pans used in taking so called flash light photographs, and refers particularly to the means for igniting the powder charge or cartridge by the light of which the picture. is taken.

The principal object of theinvention is to'ejiprov'ide simple, effective and reliable means for igniting the powder charge in Vthe pan, said 'means consisting preferably of a fuse plug provided with a length of A further object is to'so construct the said plug that it shall be entirely self contained,

and easily insertible in position, and quickly removable fornxamination or removal' of i wire.

l ,closed in the `following description thereof..- tion is illustrated in mentary detailview of the contacts and as.

other objects of the mention wiii'be dis- The preferred embodiment of the'inventhe accompanying drawing, whereine 4 Figure 1 1s a side elevational view of 'a' ,"fl'ash pan constructed according to my in.

vention.. F ig. 2 is a longitudinal sectional view takenA on the line 2-2' of Fig. 3, looking in the direction of the arrows; vFig. 3 is a bottom plan view of the improved flash' pail; Fig. 4 is a cross sectionalview thereof .taken on'the line 4 4 of Fig. 1 looking in the direction of the arrows; Fig. 5 is a frag` sociated parts employed in the' dashing. device; and Fig. 6 isla perspective view of the novel-form of fuse plug.'

Referring in detail to the .figures ofthe.

accompanying drawing, the numeral 10 designates the Hash .pan which is preferably'inl t e' ...stf'

shape 'of -an elongated comparatively 'narrow trough and is adapted to receive a suitable powder charge, designed to be tired by the means to 4be hereinafter described. The pan-.10 is .provided with a threaded Socket. '11. into which a suitable support Screws, and in any 'desired part of the wall retain the fuse Y ofthe pan, preferably in the bottom thereof', an orice 12 is formed through which the spark `for igniting the powder charge passes.

The ignition spark is preferably produced i by. the action of an electric current on a fuse, and the preferred arrangement for producing the spark is that about to be described.

Secured to the Vbaseof the pan 1 0 proximately its median part, is an insulating plate 13 having an orifice 14 in registry' with the orifice 12 in the pan. Arranged nslots or depressions in the plate 13 is a pair of metallic vcontact A springs or tongues 15 and 16, one at each side of the orifices 12 and 14, these-.contact springs'being `held in posi- N. Y., Assieiron or ONE-HALF 4T o--iuiciifiaiv n. f

at aption by insulating plates 17 vand 18 spaced f apart as shown and'being held to the plate 13 and on the contact springs by diagonallyopposite screws 1 9 which' are preferably. countersunk in the plates 17 and 18 and pass through the latter-into the plate 13.-

The contact springs 15v and16 are provided with binding posts 20 and .21, respectively,

adapted to receivethe terminals 22 and' 2 3 of wires formed into acable 24,A and .de

.,sig'ned :to vlconvey. current to the contacts from' a suitable source (not shown). Over# - lyingithe plates 17 and 18 is an insulating plate 2 5, against which the -terminals 22 and 23 'are held ,by means o'f ,the kuurledbinding screws 26 adapted to thread on the posts 20 and V21.

It lwill be noted vfrom the foregoing der scription that 'when the plates 13, 25 and 17 and 18'areassembled at the. base of thepan- 10, they form an open insulating frame, one

of the plates having an orifice alined with that in the flash pan, and the frame being so constituted as-to be adapted to receive and plug, as more fully hereinafter described.

ridap-ted for insertion between the .plates 17 and18 is thefuse plu clearlyv shown in liis plug consists wire fuse'29 which passes through the hole 30 and may be drawn across both longitudinal'faces of theshank 28, one of the faces having a slot 31 formed therein, .which the' free end 29'of.A the fuse rests. When the fu isarranged' on the plug as shown in Fig. 6, theplug may be inserted in position whereby the wire fuse 29 is melted gener ating a spark which jumps through the orifices 12 and 14 thus igniting the charge in v the pan 10. f

Having thus described my invention what I claim as new and desire to secure by Letters Patent is ze- 1. In a dnfice of the character specified, the combination with a receptacle adapted to receive a powder charge and having an orifice formed in one wall thereof, of a fra me of insulating material secured to said receptacle and having one of its walls provided with an orifice alined with the orifice in saidreceptacle, and a fuse plug adapted to be inserted in saidiframe, said fuse plug carrying a fusible wire designed to extend across the orifice in the insulatingmaterial. 2. In a device of the character specified, the combination with a receptacle adapted to receive a powder charge and having an orifice formed in one wall thereof, ofa frame of insulating material secured to lsaid receptacle and having an orifice alined with the orifice in the receptacle, a lcontact member arranged in a groove at each side of the orifice in the frame, and a fuse plug adapted to be inserted into said frame, said fuse l plug carrying a fusible wire traversing the `contacts and extending across the Vorifice in the insulating material.

3. In adevice of the character specified, the y'ccmbination with a receptacle adapted to receive a powder charge and having orifice formed in one wall thereof, of a frame of insulating material secured to said receptacle, said frame comprising upper and lower plates, and intermediate plates spaced anu away from each other, said upper plate having an orifice alined with the orifice in the receptacle, a pair of contact members carried by said upper plate, and ay fuse plug adapted to be inserted between said intermediate plates, said plug carrying a fusible wire traversing said contacts and extending across the orifice in the insulating material.

4. In a device of'the character specified, the combination with a receptacleadapted to receive a powder charge and having an orifice formed in one wall thereof, of a frame of insulating material' secured to said receptacle and having an orifice in one wall thereof in alinement with the orifice in the receptacle, contact members carried b v said insulating frame, anda fuse plug adapted to be inserted into said frame, said p lug comprising a laterally enlarged head portion adapted to have spare wire coiled thereabout and a shank portion for receiving a single strand of `wire designed to traverse said contacts and extend across the orifice in the insulating material.

5. In a device of the character specified,I the combination with a receptacle adapted' to receive a powder charge and having an orifice formed in one wall thereof, of a frame of insulating material adapted to ieceive the shank of a fuse plug and having an orifice in one of its walls in alinement with the orifice in the receptacle, contact members carried by said frame. and a fuse plug comprising a laterally enlarged head vportion adapted to have spare wire coiled thereabout and a shank portion having a longitudinal groove on each face for receiving a single strand of wire drawn through an orifice in the plug between the head and shank portion thereof, said strand being designed to traverse said contacts and extend across the orifice in the insulating frame.

In testimony whereof I have affixed my signature in presence of two witnesses.

LOUIS SCQHLESINGER.
