DAYLIGHT FILM WINDER `1 Filed Feb. 10, 1938 inf/,2m da? bj/J I 1 I a l 'rra/gey y Patented Oct. 29, 1940 PATENT- OFFICE DAYLIGHT FILM WINDER William Le Roy Lloyd, Houtzdale, Pai, assigner to Lloyd Specialty Company, Inc., Houtzdale, Pa., a corporation of Pennsylvania Application February 10, 1938, Serial No. 189,787
2 Claims.
There is an advantage in buying photographic lm in bulk meaning in comparatively large rolls instead of in the form of comparatively small rolls wound on 35 mm. spools appropriate for use in cameras.
It is the principal object of the present invention to provide a lconveniently operated device or winder by means of which bulk film can be wound onto spools in daylight.
Another object of the invention is to provide a device of the character mentioned which is simple and comparatively inexpensive in structure and convenient and reliable in operation.
Other objects of the invention will appear from the following description at the end of which the invention will be claimed.
Generally stated, the invention comprises a casing or generally rectangular box internally provided with two cylindrical chambers connected by a neck and having a detachable cover or side and a hinged lid at one end; the device also provided with a winding crank and spindle; said chambers and neck being exposed when the cover is removed so that bulk iilm may be inserted into one of the chambers with its end threaded through the neck and then the cover reapplied, thereafter by opening the lid a cartridge can be inserted in the otherchamber even in daylight and the end of the bulk film connected with the spool of the cartridge and Wound on the spool by means of the hand crank.
The invention also comprises the improvements to be presently described and finally claimed.
In the following description reference will be made to the accompanying drawing forming part hereof and in which,
Figure 1 is a side elevation of a daylight film Winder embodying features of the invention.
Figure 2 is an end view of the same.
Figure 3 is a sectional view taken on the line 3-3 of Figure 1.
Figure 4 is a sectional view taken on the line 4-4 of Figure 2.
Figure 5 is a view similar to Figure 1 with the detachable side or cover removed, and
Figures 6 and 'l are respectively a cross-section and a perspective view of the cartridge holder.
Referring to the drawing, I is a generally rectangular casing or box. Internally it is provided with two cylindrical chambers Zand 3 and of which the chamber 2 is larger than the chamber 3. These chambers are connected by a neck 4 and the neck and the two chambers are open at one of their ends and closed at the other of their ends `by the solid wall 5 of the box or receptacle, Figure 3. The other ends of the chambers and of -the neck are closed by the detachable wall or cover 6 of the box. It may be remarked that the joint between the cover 6 and the box proper is tongued and grooved as at 'l for the purpose of excluding light. The box or receptacle I is also provided with a hinged lid 8 which,
when open, serves to afford access to the cham-- ber 3. The lid 8 is shown as turnably mounted on studs 9 projecting inward from the side walls 5 and 6 of the box. The crank I0 and its winding spindle II are mounted in a bearing I2 secured to the cover or side 6 of the box. The spindle II is forked at its inner end and it is movable endwise in respect to the bearing and it co-operates with a groove inside the bearing by means of a spring-pressed detent I3. The lid 8 is shown as provided with a flange 8a and, leading through it, an opening 8b. The spindle II of the crank when pushed inwards enters the hole 8b and thus secures the lid in closed position. For the purpose of excluding light there is provided a felt lining I4 for the chamber 2 and it extends into the neck 4 and part way around the inside of the chamber 3, Figure 5. This lining may be detachably secured to place so that it can be renewed or brushed and cleaned. i 5 is a spindle provided with a head I6 and with a thread I1 which engages a corresponding thread on the inside of a socket I8 projecting inward from the Wa'll 5. I9 is a cartridge and it is provided with an inlet slot 20 open at one end and lined with felt as indcatedby dots in Figure 6. The open end of slot 20 is closed by the cover lila. The lining is omitted in Figure '7. Within the cartridge I9 there is a revolvable spool 2| provided with a cross pin 22.
The mode of operation of the described device may be described as follows: In a dark room or suitably lighted room the cover 6 is removed by unscrewing the screw I5 and a roll of bulk film is inserted in the chamber 2 and the end of the film is passed through the neck 4 into the chamber 3. Then the cover 6 is replaced and secured by means ofthe screw I5 which passes through the center of the roll of bulk film. Thereafter to wind film on the spool 2| of the cartridge I9 the lid 8 is opened and this may be done without a dark room or special light and in ordinary daylight. The end of the lm is introduced through the slot 20 `in the cartridge and its end is secured to the spool 2l. closed and the crank introduced so that the forked end of" its spindle engages with the pin The lid 8 may then be CTI 22 of the spool 2l. Then by turning the crank the film is Wound on the spool 2i which is the object to be attained. When the spool is full the film is cut and the bobbin and spool are removed from the chamber 3 for use in the usual Way.
It will be obvious to those skilled in the art to Which the invention relates that modications may be made in details of construction and arrangement Without departing from the spirit of the invention which is not limited to such matters or otherwise than as the appended claims may require.
I claim:
1. A nlm Winder for use in daylight comprising, a casing internally provided with two cylindrical chambers of which one is larger than the other and with a neck interconnecting said chambers, a lining for said neck excluding the passage of light therethrough, a detachable cover secured to said casing and forming one Wall of said chambers and of said neck so that When said cover is removed it exposes both said cylindrical chambers and the neck so that a lm may be inserted sidewise therein, a lid hingedly mounted on said casing and adapted to form part of the Walls of said smaller chamber, and a winding handle comprising an attached crank and spindle mounted on said cover so that said spindle projects into fthe smaller cylindrical chamber.
2. A film Winder for use in daylight comprising, a casing internally provided with two cylindrical chambers of different size and with a neck interconnecting said chambers, a hinged lid pivotally mounted on said casing and having a perforated ange slidable past a portion of said casing, the perforation being spaced from the edges of the flange and a Winding handle detachably secured in a bearing in said casing and projecting through the perforation in said perforated ange so as to secure said lid in closed position when said handle is in operative position.
