SPECIFICATION forming part of Letters Patent No. 698,164, dated April 22, 1902.
Application led February 1,1902. Serial No. 92,183- (No model.)
T0 a/ZZ whom it' nwty concern: Y
Be it known that we, JOHN WILKINSON and ALFRED WILKINSON, subjects of the King of Great Britain, residing at St. Oswald street, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in or Relating to Photographic Cameras, of which the following is a specification.
This invention relates to improvements in the mechanism for charging and discharging the filmseither in a box or a folding camera and in the spools therefor. Y
The object of our said v inventionis to enable the spools containing the film required for use and for the reception of the film after it has been exposed to be readily placed in and removed from thercamera.
In the accompanying drawings, illustrating our invention, and to whi`ch we hereinafter refer, Figure 1 is a rear view,with the interior exposed, of a form of camera to which'our invention may beapplied. Fig. 2 is a side view of the same.v Figs. 3 and 5 are transverse sections on line A'A and in combination with Figs. 4 and 6 show the respective positions of the mechanism to enable the spools to be removed from or placed in and retained in the camera. Figs. 7 to 13 are details of the 4aforesaid mechanism, and Figs. 14 to 17 are detailsof the spools. Y
In the views similar letters refer to similar parts. i
In photographic cameras whichhave two chambers, as a and b, one for the loaded spool and one for the spool on which the, ilm is wound after exposure, we form the spools and fix them in said chambers in the manner we hereinafter describe. We fit within each end of'said Vchambers a semicircular rest with an inwardly-danged circular end, the semicircular portions of the rests on which the peripheries of the disks on the ends of the spool are placed Vbeing equal to half the diameter of said disks. Referring to the chamber b, in which thel spool for receiving the film after exposure is placed, the restd (shown in detail in Figs. 7, 8, and 9) is caused to slide inwardly either by a spring or'may be pressed in by a spindle, as e, and is retained in the inward position, as shown in Fig. 6, by a catch, as f, so that the spool -is also xed on the spindle c.
is held between the disk g in the flanged circular end CZX and the disk g in the iianged circular end of the rest c, (shown in detail in Figs. l0 and 11,) that is xed within the opposite end of the chamber b. The disk g, which is rather less in diameter than the internal diameter of the recess in the circular end of the rest d, is secured to a disk on the inner end of the spindle e, that is passed through the circular end dx of the rest d, and between this disk and the inner side of the circular end of the rest a disk g' with notches formed in or projections formed on its edge, A ratchet at the back of said disk permits forward rotation, but prevents backward movement.
Referring to the chamber a, in which the loaded spool is placed, the rest j (shown in detail in Figs. 12 and 13) is caused to slide inwardly either by a spring or may be pressed in by a catch, as lo, which when turned down `will retain the rest in the inward position, as
vshown in Fig. 6, and hold the spool between the disk y2 in the circular endY of rest and the disk gX in the circular end of the rest c. We form the spools by xing metallic disksZ onto a spindle, as Am. These disks have one or more projections, as ZX, on or near their edges, said projections entering and rotating in the circular grooves formed between the inner surface of the flanges on the circular ends of the rests andthe peripheries of the disks contained therein. I
In order to place the spools in or take them from the chambers d and b, the loaded spool is placed in the chamber a by drawing back -iixing'it in position by turning down the catch 7c, as shown. The register c will limit the distance the spool has to be drawn back when it is required to be removed from the chamber.
After the end of the ilm has been connected to the spool on which it is wound after exposure said spool isplaced onv the rests d and c in the chamber b, the rest d having been first drawn back by the spindle c. The spool is then secured by the rest dbeing pushed in, so as to hold the spool between the disks g and gx, the rest d being kept in the inward position by the catch f. The register c will IOO limit the distance the spool has to be drawn back when required to be removed. The film is Wound onto the receiving-spool by rotating the disk g, the projections on the disk at the end of the spool engaging with the notches in or projections on the edge of the disk g', the pressure of the disks jz'and gX on the loaded spool obtained bya spring behind the catch 7c causing sufficient drag to keep the lrn properly extended. In place of the projections ZX on the disks of the spool holes or notches may be provided in said disks for projections which may be formed on the disk contained in the circular end of the rest to enter.
Ve claim as our inventionl. In photographic cameras having two chambers one for the reception of a spool with the film on which the pictures are intended to be taken, and one for the spool on which the lm is Wound after the picture has been taken the mechanism by which the spools can be placed in said chambers, retained therein, operated and removed therefrom, consisting of semicircular rests d, c and j in combination with spools with disks at their ends which have one or more projections on or near their edges, substantially as and for the purpose hereinbefore described.
2. A film-carrying spool for a camera having flat disks on its ends and a projection at the outer edge of the disks, in combination with a rotatable disk, adapted to bear against said fiat end to rotate it, substantially as described.
3. A photographic camera having a spool with disks at its ends and semicircular rests in Which the disks are adapted to be placed and means for rotating the spool, substantially as described.
4. A photographic camera having a spool with disks at its ends, semicircular rests in which the disks are adapted to be placed and registers in the rests, substantially as described.
5. A photographic camera having a spool with disks, semicircular rests, rotatable disks in the rests,means to rotate them,and a spring means for holding said rotatable disks against the spool ends, substantially as described.
In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
. JOHN VILKINSON.
