TO A. D.
MARBLE AND ONE-FOURTH TO SUSAN ASSIGNOR, BY DIRECT AND MESNE ASSIGN- O. TAYLOR, OF
DAYLIGHT FILM-DEVELOPING APPARATUS.
To all whom it may concern. 2
Be it known that I, Josnrn LE CoMPTn, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma, Okla- 5 homa, have invented certain new and useful Improvements in Daylight Film Developing Apparatus, of which the following is a specification.
My invention relates to daylight film developing apparatus, in which a film and developing tray compartment is provided, with viewing glasses in its walls by which to observe the process of developing; and a compartment for the developing liquid, which affords a kodak rest, all of which will hereinafter be fully explained.
The objects of my invention are first, to provide an apparatus which will avoid the necessity of constructing and maintaining a dark room for the development of films, such as are commonly used with kodaks; second, one with which a kodak can be conveniently carried; third, one having a place for carrying the developing liquid; fourth, one which requires no timing; fifth, one in which the developing process can be observed; sixth, one which can be used as well at night as by day; I accomplish these objects by the mechanism illustrated in the accompanying drawings, forming a part of this specification,
in which- Figure 1 is a rear perspective of my daylight developing apparatus; Fig. 2 is a front perspective of he same with portions broken away; Fig. 3 is a vertical section of the door: ig. 4 is a central vertical sectional view of the apparatus; Fig. 5 is a front elevation of the apparatus as arranged for transportation. Similar letters refer to similar parts in the 40 several views.
Referring to the drawings, A designates the rectangular upright cabinet portion of the apparatus firmly secured to the base B a cheap and eflicient way of constructing the cabinet is to groove or channel the corner posts a and use thin sheets of wood for the walls with their vertical edges inserted in said grooves as in the present case, although metal may be used in the construction of the entire framework of the apparatus. The top C is firmly secured to the corner posts a, and has a carrying handle 0 secured thereto.

Quite centrally located in the rear wall of the cabinet is a rectangular opening which constitutes the mouth of the light box E having a roof 1, a floor 2, a right wall 3, a left wall 4 and a rear or back wall (2, being formed by securing said roof, floor and walls to the rear cabinet wall (1 around said opening, see Figs. 1 and 4.
For supporting and actuating the fiim D the roller b is provided, having one of its horizontal journals 6 passed through the rear wall a of the cabinet and has a crank e for turning said roller, its other ournal c being supported by a vertical bar 0 having its ower end secured to the end wall 6 of the light-box E, and, to afford access to the interior of the cabinet for the adjustment of the film D upon the roller b, the door H constituting the front wall of the cabinet has its lower end hinged to the base B, and has a knob or block secured to its outer surface y which to pull the door open. See Fig. 2, which shows a portion of said door broken away to disclose interior parts.
To guard against the admission of light into the cabinet while adjusting the film D upon the roller 1), the opaque bay-windowlike hood 72/ is provided, having its edges tacked or otherwise secured to the front of the cabinet, and having two hand-holes hcut therein with their edges provided with elastic cord to closely contact the wrists and arms of the operator.
' The cabinet base B is extended in one direction two or more times its width to form J of the bottl moval of the tray d a dovetail groove is cut longitudinally in the upper central portion of the base B extending nearly the entire length and fitted therein is the sliding tray removing bar 7: having a pan 7t" resting upon and secured to its inner end forming a seat or rest for the tray (Z, see Figs. 1 and 4. The partition between the cabinet and the ottle-case being cut away necessitates some means for excluding the light during the process of inserting and removing the tray d, in which a dark curtain, or a sliding door in Fig. 4; sufiicient light being admitted into could be used, but a wing-door Z as ferred style, form and construction of my resent case is deemed preferable, in which paratus it will be understood that various the upper edge of the door is pivoted to the 1 changes within the scope of the claims may corner posts a, a, one of its pivots being proj be made without departing from the spirit of vided with a knob m by which to turn the myinvention, which,
