Application filed October 11, 1907. Serial No. 397,000.

To all whom it may concern:

,Be it known that I, BnNJi-mm iiANASION United States, residing at Whitman, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Continuous Photographic Printing Apparatus; and I do hereby declare the following to be a full, clear, and exact descri tion of the inven tion, such as will enable ot iers skilled in the art towhich it appcrtains to make and use. he same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in continuous printing apparatus for photographers use, and com )r'" s various details of(()listlll(ti0li and com vinations and arrangements of parts which will be hereinafter fully described and then speciiicallv defined ,in the appended claims.

l. illustrate my invention in theacconn panying drawings, in whichr Figure 1 is a perspective view of the apparatus. Fig. the under surface of the casing. Fig. 3 is a longitudinal sectional view on line 3' -3 of Fig. 1. Fig. 4 is a sectional view on line -i--4 of Fig. 3. Fig. 5 is a sectional view on line 5-5 of Fig. 3, and Fig. 6 is a sectional view on line (i-(5 of Fig. 3.

Reference now being bad to the details of the draw ings by letter, A designates a casing continuing the o )erat'ive parts of the apparatus andjs provided with two compartments, designated respccth ely by letters A and A", for the reception of 'thc lilm of negatives. One of said compartments A has arcel B which is shown clearly in Fig. 5 of the drawings held in place by means of a spring- )rcsscd )in B the opposite end of the reel being held upon a pivot B, which is a common mechanical constriu-tion in holding reels in cameras.

C -C designate two rollers, preferably covered with rubber, and adapted to feed the sheet of printing paper 1) forward from the; reel B. t

E designates a springpressed block to which the screw E is swiveled, the shank portion of said screw passing through an aperture F3 in the casing and provided with a thumb nut E" thereon. It will be noted that the shank portion of said stem has shoulders I) which, when the stem is pulled outv in the hinged at I.

2 is a perspective view showing Fig. 3 of the drawings. Said printing pa 'er D, it will be notedfis held b the block t against the negatives G, whic are mounted within the casing and to which light clearly in which a door I is applied, the latter being Referring to will be seen a slide N having slots N formed therein, said slots receiving the headed pins 0 and N designate lugs projecting from said slide whereby the same may be moved back and forth to open or close a slot Q formed in the side of the casing and in which a slide P may be inserted when it is desired to change the negative or for any other purpose.

In order to sever the strip after being printed, I. provide a cutting device consisting is pivoted and T designates a post secured to the latter and having a button T at its end between said button and the top of the ass ing. The strip of printing )aper is adapted to pass between the cutting lades and to be severed thercb as the movable blade is deressed, thereby effecting a shearing cut. The coiled spring T before referred to, serves to return the pivotal shearing biade R to its normal position after having been deressed.

Referring to Fig. 2 of the drawings Will be seen. a sight aperture J, COVQI '6(i preferably by a rub 1 glass whereby the marks upon the paper may be viewed without effecting the sensitiveness of the paper. One of said oompartments is provided with a hinged lid A", as shown in l ig. 2 of the drawings, suitable buttons A being provided to hold the covers closed. 4

In operation, the roll of printing paper is first wound upon the reel and the latter inserted in one of the compartments and fed between the rollers O and the spring-pressed block E and the negative. W hen 1t is desired to make an exposure, the cover I is swung position shown in dotted lines, may be given: a partial rotary movement in order to engagethe inner surface of the casing, as shown niav have access through the opening 'to of a. stationary knife R, to which a blade R and T designates a coiled spring interposedv open, after which by turning the thumb screw S lixed to one of said rollers C, the

the outside of the casing to hold the stem" Figs. 1 and 2 of the drawings printing sheet may be fed through into the compartment A and severed by the de ression of the spring-pressed shearing l) ade. After the exposure is made, the cover I may 5 be closed until a fresh piece of the aper is brought forward for a new print. en it is desired to remove-the negative, the block E may be Withdrawn under tension of the sprin E from contact with the printing paper w rich holds the same ti htly against the negative. In the event of ms being used, a transparent plate ,is first inserted in the cas ing to assume the position taken by the last me ative and a ainst which transparent plate a mmay be eld.

From the foregoing, it will be noted that, by the provision of an apparatus embodying the features set forth, a simple and eflicient apparatus is afforded whereby a continuous series of pictures may be printed from a negative and severed individually, if desired, and so arranged that it may be, adapted for use either with glass negatives or films.

What I claim to be new is 1. A printing apparatus comprising a eas ing having a reel therein upon which printing aper is adapted to be wound, means for ceding paper from one compartment into another, negative holding means adjacent to 30 an opening in the casing, -a spring-pressed member adapted to hold the printing paper against a negative over said opening, one of the sides of the casing having an elongated slot adapted to receive a slide, headed pins upon the side of the casing, a closure comprising a strip of metal having transverse slots through which said pins extend, said closure adapted to have'a sliding movement over said slide, as set forth.

2. A printing a )paratuscom rising a casing having a reel t erein upon w ich printing paper is adapted to be wound, means for feeding paper from one compartment into another, negative holding means adjacent to an o enin in the casing, a spring-pressed mem )er adapted to hold the printing paper against a negative over said openin one of the sides of the casing having an elongated slot adapted to receive a slide, headed pins upon the side of the casing, a closure comprising a strip of metal having transverse slots through which said pins extend, lugs projecting lrom the slide adapted to cover said slot, as set forth.

In testimony whereof I hereunto {all}; my signature in the presence of two witnesses. BENJAMIN HANASION BRAGG WVitnesses:
