To all whom it may concern: 7

Be it known that I, EDWARD J. BROGAN, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented new and useful Improvements in Photographic- Printing Frames, of which the following is a s ecification.

ob'ect of the invention isto provide a frame or use in making photographic prints.

The invention embodies, among other features, a device wherein a tracing or picture, from which it is desired to make a print, is fed into a casing to lie in an exposed position immediately in front of a sensitized paper, the impression of the original picture being then transferred on to the sensitized pa or by the action of the sun or other light, after which the sensitized aper, together with the picture, is remove from the casing and the sensitized paper is then subjected to various chemical treatments in order to reproduce a copy of the original picture.

My device is particularly adaptable for use in making blue prints by the action of the light of the sun and for this reason the device is preferably mounted in a window with a portion of the device projecting outwardly therefrom and having a face thereof exposed to the sun so that a clear and effective blue print can be readily and quickly produced.

In the further disclosure of the invention reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a vertical sectional view of a window casing showing my device mounted therein, the device being shown in elevation;

ig. 2 is a similar View, the device being shown in vertical section; Fig. 3 is a horizontal sectional view taken on the line 33 in Fig. 1; Fig. 4 is a vertical transverse sectional view taken on the line 4;4= in Fig. 1; and Fig. 5 is a transverse sectional view taken on the line 5-5in Fig. 1.

Referring more particularly to the views, I disclose a window casing 10 having the usual sill 11 and sash 12, a casing 13 being mounted to repose upon the sill 11 and having secured to the front end thereof a downwardly extending auxiliary casing 14, the

forward end of the casing 13 being projected beyond the sill in order that the auxiliary casin 14 can be arranged to extend downward y at an angle to the casin 13, the lower part of the sash 12 being adapted to engage the upper face of the casing 13 to secure the casing 13 on the sill ll, an suitable locking member 15 being re erably employed for engagement with t e sash 12 to retain the same in rigid position and lock the casing 13 on the sill 11.

The rear end of the casing 13 projects inwardly beyond the sill 11 and mounted to swing thereon is a closure 16, a slotted supporting member 17 being secured to the closure 16 and having arranged to operate in the slot thereof a suitable pin 18 secured to a side of the casing 13, the slot in the supporting member 17 being of sufficient length so that when the closure 16 is in open position the same will lie in the horizontal plane of the lower side or bottom of the casing 13, whereas when the closure is moved into closed position, the mentioned closure will close the rear end of the casing, as shown, a suitable catch 19 being provided on the closure 16 and adapted for engagement with the casing 13 to retain the closure in closed and locked position.

' A plurality of uprights 20 are secured to the closure 16 and extend laterally thereto and journaled on the uprights and between the same is a roller 21 adapted to contain a roll of sensitized paper 22. A partition 23 is preferably provided in the rear end of the casing 13 to form a compartment 24 adapted to receive the roller 21 and roll of sensitized paper 22 when the closure 16 is moved into closed position, the mentioned compartment being light-tight so that the sensitized paper will not be subjected to the light when the device is not in use, a horizontally arranged slot 25 being provided in the partition 23 and through which the sensitized paper and the original picture from which it is desired to obtain a print, are passed when it is desired to produce a print on the sensitized paper.

Bearings 26 are mounted to slide in slots 27, formed in the side walls of the casing 13 and journaled on the said bearings are coacting

rollers

28, 28*, one of said rollers being arranged above the other in order that the sensitized paper can be fed therebetween, suitable headed tension members 29 being journaled in the side walls of the casing 13 and having threaded connection with the bearings 26 in order that the bearings can be advanced or retreated in the slots 27 when the said tension members are rotated relatively to the casing 13.

Suitable rollers

30, and 30 are journaled in the front end of the casing 13 and journaled in the lower part of the auxiliary casing 14 are rollers 31, 31, an endless trans parent apron 32 being arranged within the casing 13 and auxiliary casing 14 to pass around the

rollers

28, 30, 31*, 31 and 30,- the

rollers

30, 31 and 30 being adapted to act as guide rollers for the apron while the roller 31 constitutes one of the end rollers at the lower end of the auxiliary casing 11 and the roller 28 constitutes the other end roller in the rear end of the casing 13. Ina similar manner, an endless oqaque apron 33 is mounted to pass over the rollers 28", 30, 31 and 30", the roller 31 constituting an end roller at the lower end of the auxiliary casing 14 and the roller 28 constituting an end roller at the rear end of the casing 13, while the

rollers

30 and 30 act as guide rollers for the opaque apron 33, the mentioned rollers 30 and 31 being also adapted to act as guide rollers for the transparent apron 32 as mentioned heretofore, and as will be readily seen by referring to Fig. 2. It will now be seen that by operating the tension members 29 to actuate the bearings 26 in the slots 27, the tension of the aprons 32 and 33 can be readily adjusted.

A shaft 34 is extended from one end of the roller 28*, said shaft also constituting the means whereby the roller is journaled on one of the bearings thereof and the said shaft being adapted to project beyond a side of the casing 13 and havin keyed thereto a toothed drum 35, a suitab e handle 36 being also keyed to the free end of the shaft 34 for the purpose of imparting rotation to the drum 35, thus also rotating the coacting

rollers

28 and 28*. A bracket 37 is secured to the bearing having the shaft 34 journaled therein and the said bracket extends outwardly over the drum 35, the mentioned bracket being bifurcated to form a track 38 on which is mounted to slide a grooved wheel 39 having a pin 40 depending therefrom and operable in the grooves formed between the teeth of the drum 35, it being readily understood that the grooves in the mentioned drum 35 are cut sufiiciently deep in the drum so that when the drum is rotated, thus advancing the grooved wheel 39 over the track 38, the drum will be locked in rigid position and prevented from being turned at the moment the pin 40 reaches the extremity of the groove in the drum, it bein understood that the groove is of a contlnuous nature, as formed by the teeth on the drum,

In the use of the device described, an end of the sensitized paper 22 is passed through the slot 25 in the partition 23 and between the coacting rollers 28* and 28*, after which the tracing is also fed between, the

rollers

28, 28 and then by means of the handle 36, rotation is imparted to the drum 35, thus resulting in the rotation of the

rollers

28, 28* and impartin rotation to the aprons 32, 33, the sensitize paper and tracing being received between the aprons so that the sensitized paper and tracing will be simultaneously advanced into the auxiliary casing 14, the front face of the auxiliary casing being open in order that the tracing and sensitized paper will be readily exposed to the light of the sun. The length of the groove on the drum 35 is made in proper proportion to the length of the casing 13 and auxiliary casing 14 so that at the moment the pin 40 of the carriage 39 reaches the end of the groove, thus locking the drum against rotation, the tracing and portion of the sensitized paper beneath the tracing will lie in the open part of the auxiliary casing 14. The tracing and sensitized paper are now exposed to the light of the sun for a time suflicient to produce an impression upon the sensitized paper, said impression being a duplicate of the picture on the tracing, and the handle 36 is then rotated in the opposite direction to reverse the former rotation of the drum and also reverse the former rotation of the rollers 28"-, 28 thus retreating the tracing and sensitized paper from the auxiliary casing 14 into the casing 13 vand thence outwardly through the slot 25 in the partition 23, after which the rotation of the handle 36 is again reversed to receive a new portion of the sensitized paper and another tracing.

The transparent apron 32 can be conveniently made of celluloid or other flexible transparent material and the apron 33 is preferably made of canvas in order to present a roughened surface that will grip the sensitized paper to simultaneously advance the sensitized paper and tracing in the casing 13 and auxiliary casing '14, the drum 35 and pin 40, operating in the continuous groove of the drum, being adapted to limit the advancement of the sensitized paper and tracing in the auxiliary casing 14, as mentioned heretofore.

By providing a device of the character described, the process of photographic printing can be efliciently and expeditiously carried on and by having the sensitized paper and tracing arranged to lie between the transparent apron 32 and opaque apron 33, the mentioned tracing and sensitized paper will at all times lie flat and smooth, the tension of the aprons 32 and 33 being adapted to retain the tracing and sensitized paper in close relation so that an accurate and clear print can be obtained upon the sensitized paper.

It should be noted that by arranging the casing 13 and auxiliary casing 14 in the manner described heretofore, the device disclosed will take up far less room than the devices now generally used and which are usually 0 erated over a track extending from within a building to the exterior thereof, and it will be further noted that my device can be readily and quickly removed from the window casing 10 when it is not desired to use the same.

Having thus described my invention, I claim:

1. In a device of the class described, the combination with a casing, of an auxiliary casing projecting from the front end of the said casing, a closure for the said casing, a roller journaled on the said closure and adapted to contain a printing material, rollers journaled in the said casing and said auxiliary casing, a continuous transparent apron mounted to operate over a plurality of the said rollers, a continuous opaque apron mounted to operate over aplurality of the said rollers, and means for actuating the said aprons and feeding the said sensitized material therebetween.
