Patented Nov. 7, 1939 ATTACHMENT FOR PHOTOCOPY MACHINES Edward R. Sahel, Rochester, N. Y., assignor to The Haloid Company, Rochester, N. Y., a corporation of New York Application September 10, 1938, Serial No. 2293232 5 Claims. (Cl. 88-24) This invention relates'to an attachment for photocopy machines, of the general type that utilizes a continuous strip of photocopy paper, a portion of which is fed through and cut off after exposure, and it has for its object to afford a mechanism that can be readily applied to any conventional photocopy machine and is operable to permit making copies or enlargements from any selected portion of a miniature continuous film.

The invention has for a further purpose to afford a structure that is particularly applicable to the enlarging of portions of continuous film such as used for photographing checks in banks and for making other records where it is desirable to select a particular part of such film for enlarging.

An additional purpose of the invention is to afiord a mechanism attachable to a photocopy machine preferably as a unit, and which includes film supporting and winding means by which any part of a film can be selected for reproduction, and which is positionable to project the image of the selected portion into the projection opening of the photocopy machine on to the light sensitive copy paper, and is also movable to a position which projects the image downwardly on to a copy board or screen, thereby enabling the operator readily to select and bring any desired portion of the film to the proper position for making the required copy.

Another object of the invention is to provide a construction that is simple and practical, which is efficient for the purposes in view, easy to operate, and which can be manufactured at a reasonable cost.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the specification.

in the drawings:

Fig. 1 is a side elevation showing the application of a preferred embodiment of the invention to a conventional type of photocopy machine;

Fig. 2 is a side elevation looking in the oppo site direction;

Fig. 3 is a side elevation looking in the same direction as Fig. l, with the carrier frame swung upwardly for projecting the image downwardly on to the copy board or screen;

Fig. 4 is a front elevation with the lamp housing swung outwardly to permit access to the film and film track, and

Fig. 5 is a horizontal sectional view taken centrally of the lamp housing in Fig. 1.

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughoutthe several views, the invention is illustrated in one practical embodiment in the form of a unitary assembly that includes a supporting member consisting of a block I that is suitably fastened to the front plate 2 of the photocopy machine, while 3 designate oppositely arranged bars that are pivotally mounted on the block I and form part of a carrier frame upon which the parts now to be described are all mounted, and which can be swung out of the way when not in use to permit operating the photocopy machine in the usual way.

The carrier frame includes a central portion 4 having a suitable projection opening therein over which the film 6 is adapted to be adjustably positioned, the film being mounted on and wound between the spools I and 8, which are supported respectively on arms 9 and I 0. In order to enable the operator to adjust the film readily to any desired position, it travels between two feed rollers ii and I2, one of which is mounted on a shaft i3 that carries an operating handle M at one end and a pulley l5 at its opposite end, while it is a belt connecting said pulley i5 with a pulley I! mounted on the shaft which carries the lower spool 8.

The image is projected by means of light from a lamp in the lamp housing '2! which is pivoted to the carrier frame so as to swing laterally to permit inserting the film, the lamp housing being held in operative position by a spring catch 22 which engages the plate 23 at the forward part of the lamp housing andretains it against the central portion 4 of the carrier frame, it being understood that the film travels in a track that is provided between the plate 23 on the lamp housing and the central part i of the carrier frame.

The lamp housing 2! is provided with a suitable condensing lens located between the lamp and the film, while bnthe opposite side of the film is provided a suitable projecting lens located in a lens barrel 24, the latter being positionable when in operation in the projection opening of the front plate of the photocopy machine. c

When using the device, the usual lens and prism assembly is removed from the projection opening in the photo-copy machine, and the projecting lens in the lens barrel 24 being located in said opening, projects an image from the selected part of the film on to the light sensitive p p It is essential to provide means enabling the operator to select any particular part of the film to be copied, and this is accomplished by swinging the carrier frame upwardly to the posi-= tion shown in Fig. 3, it being held in such position by a spring catch 25 engaging one of the bars 8. When in this position, the image can be projected downwardly on to the copy board of the machine or to a suitable screen, and the operator may, by turning handle it, wind the film until the particular part that is to be copied is located. The carrier frame is then swung downwardly to the operative position shown in Fig. l, where it is ready to project on to the sensitized paper when the exposure is made.

It will be understood that the lamp housing is normally maintained in closed position as shown in Fig, l, and is swung to its open position only for the purpose of threading a film into the machine, or permitting access to the film or film trash,

While the invention has been described in com necticn with the particular construction shown, it is not confined-to this precise arrangement, and the application is intended to cover any modifications or departures that come with in the purposes of the improvement or the scope of the following claims,

I; claim:

1. The combination with a photoco y machine including a front plate having; a p ection openin therein, of a supporting me" ow tachaiole to the front plate above said projection opening, a carrier frame pivotally secured to said supporting member, said carrier frame including upwardly and downwardly extending arms, film supporting spools mounted on said arms, film winding means on the carrier frame, a lamp housing pivotally mounted on the carrier frame on one side of the film, a condensing lens in smd lamp housing, a projecting lens and lens barrel on the other side of said said lens barrel being positionable in the projection open= ing in said front plate, and the carrier frame being shiftable on said supporting member to an upward position for projecting an image from the film downwardly.

2. In a photocopy machine, the combination with a vertically disposed front plate having an opening adapted to receive a projecting lens, a carrier frame pivotally mounted on said front plate at a point above said opening, a housing on said carrier frame, a lamp and condensing lens in said housing, a projecting lens and lens barrel mounted on said carrier frame, said projecting lens being positionablein said opening of the front plate for projecting an image into the photocopy machine, and means for supporting and feeding a film on the carrier frame between said housing and said lens barrel, the carrier frame being tiltable about a point above said opening in the front plate and operable to support said lens barrel in. said opening or to support the lens barrel in a vertical position so as to project an image downwardly on to a horizontal screen.
