Improvements in Magazine Photographic Cameras.
WILLIAM JAMES SPURRIER, 3 Queenswood Road, Moseley, Birmingham, i
the County of Worcester, Manufacturer, GEORGE HOUGHTON, 89 High Holborn,
London, in the County of Middlesex, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to magazine photographic cameras, principally of the hand
typé, although the same may be used with stands. The magazine is inserted into
a cylindrical or other conveniently arranged receptacle attached to the camera, in
which the said magazine, which is provided with circular bearings surfaces, can be
easily rotated. The sensitive plates (glass or otherwise) are inserted into carriers
of known construction, and gravitate, as the camera is moved into the required
position, from the magazine through a slot, into a groove in the rear of the
exposing chamber of the camera. To remove the plate out of the groove and to
return it into its proper position in the magazine, the said magazine requires to
be rotated, stopping half way in the revolution and giving the instrument a rocking
movement, with the magazine downwards. The plate then passes, through another
slot, at the other side of, and into the other end of the magazine.
We will proceed to more particularly describe, and ascertain the nature of our
invention by means of the following statement and accompanying drawings.
Figure 1. represents a vertical section of a magazine camera, constructed and
arranged according to our said invention.
Figure II. represents (partly in section) the elevation of the magazine end, or
what is the top of the camera when a photograph is being taken. Fig. 5. shows the
sliding lid, with which the magazine is provided, for the purpose of the magazine
being filled and emptied, and is inserted in this end, and is retained in position by
door D.
Figure 3. is a plan of the bottom end of the magazine, showing the slots through
which the plates pass in and out of the magazine.
Figure 4. is a section upon the dotted line A B Fig. 2, showing the arrangement
of the plates and the outside or top end of the magazine.
Figure 5 is the plan of top of magazine showing, the sliding lid, partly with-
drawn, J.
A is the case of the camera, of the shape and configuration, shown by Figures 1
and 2, provided with the cylindrical chamber C, C1, for the reception of the
rotating magazine B. The exposing chamber A1 or camera proper, with the
necessary fittings, for the taking of photographs.
.D is a lid or door covering that end of the camera, E is the thumb piece for
rotating the magazine. F is a spring to catch into notches provided for that
purpose in the ring, G and G 1, which said ring, is fixed onto the lid or door D.
H is one of the pair of grooves, in which the plate is held during exposure. I is a
dial provided with the necessary quantity of figures to register the exposures made,
and also with notches or teeth at its outer edge, for the purpose of being moved
forwards, one notch or number, at each revolution of the magazine, the dial being
so arranged that the spring F at each revolution comes into contact with a notch.
K and K 1 are the respective slots in the bottom of the magazine for the inward
and outward passage of the plates.

page_text: Having now set forth the nature of our invention, and the manner, in which
the same is to be performed we declare that what we claim is :-
In magazine photographic cameras providing the same, with a rotating
magazine in a cylindrical or its equivalent chamber, and the necessary catches,
slots, and grooves, for the consecutive exposure, of a number of sensitive plates.
Dated this 26th day of January 1894.
