PRINTING- PROJECTOR.

Application led May 4,

To aZ z/zom if; may concern.'

Be it known that I, Trionns Frisian li-innivnv, a citizen oi' the United States, residing at Fort Lauderdale, in the county oi Broward and State ot Florida, have invented certain new and useful Improvements in a Printing Projector, oi which the following is a specification.

rlhe present invention relates to what I term a printing projector and relates to the art oi' reproduction by employing the principle of photography.

rIhe invention contemplates the provision ot a casing having means therein for supporting an object and a source oi illumination directed onto the objectso that the image thereof may be projected through a lens located between the source of illumination so as to be directed onto a sensitized. sheet. The image may be projected directly onto the sensitized sheet it a negative is to be made, but it a positive reproduction is desired, a mirror is used so that the projection is reflected to a shelt supported to one side ot the casing.

An important object oi the invention is to provide a printing projector of this nature which is exceedingly simple in its construction, capable ot being operated easily and quickly, one which is inexpensive to manufacture and maintain, thoroughly etticient and reliable in use, and otherwise well adapted to the purpose tor which it is designed.

lith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features ot construction, and in the combination and arrangement ot' parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of the invention embodying the principle thereo'l:l showing the hinged side open,

Figure 2 is an end elevation therco't', and

Figure 3 is a detail perspective ot an attachment.

Referring to the drawing in detail, it is to be noted that I have illustrated what might be considered the mere essentials ot the invention in order to illustrate an operative, useful, and simple example of the invention. The letter C indicates generally a casing, which includes a bottom 5, pair oi ends 6, a pair of sides T Iand 8 and a top 9. The side 1925. Serial No. 27,824.

8 is hingedly mounted as at 10 so as to aiiord easy and ready access to the interior of the casing. A plurality of vertically spaced cleats 11 are mounted on the inner surfaces ot the ends 6 and aii'ord means for holding a panel 12 in diiterent vertical positions. This panel 1121 is provided with spring clips 13, or any other suitable means for supporting on the panel an object 14 which may be in the form oi a printed sheet, a photograph, or any other object which it is desired to reproduce. n the present example of the invention, two sources oi' illumination 15 are illustrated as depending from the top 9 downwardly into .the casing, and preferably consists of ordinary electric bulbs with shades and reflectors disposed thereabout for directing the rays ot light downwardly onto the object 14. A lens 16 is disposed inthe top 9 between the two sources ot illumination 15, so that the image of the object 14 will be reflected therethrough.

As is well known, the object will be inverted when projected through the lens 16. I, therefore, provide a standard 17 rising from the top 9 and having slidable thereon a bracket 18 which includes the sleeve 19 that receives the standard 17. A spring 20 projects from the bracket 18 and frictionally engages the standard 17 in order that the bracket may be placed in diii'erent adjusted positions on the standards after which the set screw 21 may be tightened. A mirror 22 is pivotally mounted on the bracket 1S in any suitable manner and receives the image from the lens 16 as .is indicated to advantage in Figure 2. Arms 23 are fixed to the side Z being suitably braced as at 24, and extend upwardly and slant away from the side 7. Between the extremities of the arms 23 there is pivotally supported a shelf 25, on which a sensitized sheet is disposed so that the image from the mirror 22 may be directed thereon. The reproduction which will be formed on the sensitized sheet will be a positive reproduction. At times, oi course, it is desirable to make negative reproductions. This may be done by removing the mirror 22. Brackets 27 are mounted on the exterior surfaces oi the ends 6 in Vertical alignment and have set screws. A frame 28 with av plate glass panel 29 therein is supported on rods 30 which are receivable in the brackets 27 so that this plate glass panel may be held at different adjusted distances above the top 9. By placing the sensitized sheet thereon, the image will be projected directly thereon and a negative reproduction will be made.

The important idea contained in this printing projector is the provision of a projector which prints through the use of indirect lights. It is apparent that numerous refinements may be incorporated with the essentials which I have described in order that the exposure may be automatically controlled, and in order that the sensitizedy sheets may be quickly replaced for quantity reprodu/ction. I therefore Wish it understood that numerous changes in the details of construction, in the sizes, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what. I claim as new and desire to secure by Letters Patent is zl. A printing projector of the class described, including a casing `formed from a bot-tom, ends, sides slanting upwardly toward each other, and a top, cleats on the ends interiorly of the casing, a panel supported in said cleats, sources of illuminationsuspended from the top in the casing for directing rays of light onto the object on the panel, a lens disposed in the top bctween the sources of illumination to receive the image from the object, and project it outwardly of the casing.

2. A printingprojectorl of the class described, including avv casing formed from a bottom, ends,- sidesslantin-g upwardly toward'-y each otheiyand al top, cleatscon the ends interiorly oi" the casing, a panel supported in said cleats, sources of illumination suspended from the top in the casing for directing rays of light onto the object on the panel, a lens disposed in the top between the sources of illumination to receive the image from the object, and project it outwardly of the casing, a mirror adjustably mounted on the casing` for receiving the image from the lens.

3. A printing projector of the class dcscribed, including a casing formed from a bottom, ends, sides slanting upwardly toward each other, and a top, cleats on the ends interior-ly or' the casing, a panel supported in said cleats, sourcesorn illumination suspended from t-he top in the casing for directing rays oi" light onto the object on the panel, a lens disposed in the top between the sources of illumination to receive the image -from the object, and project it Outwardly of the casing, a mirror adjustably mounted on the casing :tor receiving the iu'iage from the lens, and a shelf adjustably supported to the side of the casing for holding a sensitized sheet to receive the image from the mirror.

4. A printing projector of the character described including a casing formed from a bottom, ends. a pair ot sides slanting upwardly Vtoward each other and a top, an object supporting panel adjustably supported between the ends in the casing, a source ot illumination supported by the top ot the casing for directing rays of light onto the object mounted on the panel, a lens disposed in the top iter receiving the rci'iceted rays from the object and projecting theu'l exteriorly of thejcasing, and a sensitized sheet supporting means disposed ctteriorlj,v of the casing for receiving the image projected tlnough the lens.

In testimony whereof I ailix mv signature.
