IMPROVEMENTS. IN PHOTOGRAPHIC CAMERAS
Year: 1885

page_text: I, JOSHUA BILLCLIFF of 27 Richmond Street, Boundary Lane Chorlton-on-
Medlock, Manchester in the county of Lancaster Manufacturer of photographic
Apparatus do hereby declare the nature of my invention for IMPROVEMENTS. IN
PHOTOGRAPHIC CAMERAS to be as follows:-
This invention is for the purpose of facilitating the operation of removing the
slide that contains the sensitive plate from a horizontal to a vertical position, or
from a vertical to a horizontal position as may be required, and consists of an
improved arrangement or form of a camera body in conjunction with that part of
the camera that carries the slide containing the sensitive plate termed the adapter,
by which the said adapter may be placed in either of the above positions without
being detached from the camera body.
In those cameras that have hitherto been constructed with the adapter formed
separately from the body, when the adapter is required to be removed from the
camera body, the camera body is weakened and to obviate this defect, it is
necessary during manufacture to strengthen the camera body with extra plates or
other similar means.
In this invention I construct the camera body separately and independently.
The back of the camera body I make with an opening of a circular form: the
edge of this opening is either rebated or flanged: the adapter I construct of the
same shape and size as the camera body, the camera body with this invention not
requiring to be larger than the adapter.
:
To the adapter on the inner side, or that side which is placed next the camera
body I attach corresponding parts to fit into the rebates or flanges in the circular
opening formed in the camera body: the adapter is by these means secured to the
camera body and at the same time is free to be moved round as required, so as to
obtain an upright or horizontal picture without the said adapter being detached
from the camera body, and without removing or altering in any way the position
of the camera body or any other part of the camera.

page_text: I, JOSHUA BILLCLIFF of 27 Richmond Street Boundary Lane Chorlton-on-
Medlock, Manchester in the county of Lancaster, Manufacturer of Photographic
Apparatus do hereby declare the nature of my invention for IMPROVEMENTS IN
PHOTOGRAPHIC CAMERAS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
'
This invention is for the purpose of facilitating the operation of removing the
slide that contains the sensitive plate, from a horizontal to a vertical position, or
from a vertical to a horizontal position, as may be required, and consists of an
improved arrangement or form of camera body, in conjunction with that part of
the camera that carries the slide containing the sensitive plate, termed the adapter
by which the said adapter may be more readily placed in either of the above
positions, without being detached from the camera body.
In this invention I construct the camera body separately and independently of
the adapter: the back of the camera body I make with an opening of a circular
form: the edge of this opening is either rebated or flanged: the adapter I construct
the same shape and size as the camera body, the camera body not requiring to be
larger than the adapter.
To the adapter on the under side, or that side which is placed next the camera
body, I attach corresponding parts to fit into the rebates or flanges formed in the
circular opening on the camera body: the adapter is by these means secured to the
camera body, but is free to be moved round as required; so as to obtain an
upright or horizontal picture, without the said adapter being detached from the
camera body, and without removing or altering in any way the position of camera
body, or any other part of the camera.
In order that my invention may be fully understood I now describe the accom-
panying sheet of drawings. In the several views illustrated therein, similar letters
refer to similar parts.
Fig. 1. shows side view of a camera with the adapter 6 fitted to the camera
body a, by the internal flanges and grooves d, d¹, and c, as hereinafter described.
Fig. 2 represents a vertical section of camera body a, with the adapter b
detached, and Fig. 3 is the end view of adapter separated from the camera
body a, to illustrate more clearly the grooves and flanges c, d, and d by which the
camera body and adapter are connected.
Fig. 4 is a section of camera body a on line A. B. in Fig. 1, and shows the
parts cd, and d¹ in their relative positions when the adapter b is connected to the
camera body a.
Fig. 5 is a back view of camera as represented in Fig. 1. In this view the
adapter b is turned partly round to illustrate the action of the grooved or rebated
parts and flanges c, d, and d attached respectively to the camera body a, and the
adapter b.
In the construction of these parts I form first the camera body with a rectangular
opening of the size required as shown at e in Fig. 6.

page_text: I then form a circular groove f: I divide the parts g at the line h: those parts
which are thus cut off, I reverse, and then attach them to the camera body a, by
the screws or other suitable means: I thus form the grooves c and the flanges d
and dat one operation The flange d' thus formed on the camera body a, fits into,
and revolves in the groove c, formed on the adapter b, by the attachment thereto of
the parts.g, and the adapter b is thus united to the camera body a.
Fig. 7 shows a modification of my invention, metal plates being used in lieu
of parts g, previously described.
I do not claim the revolving principle of an adaptor in application to a photo-
graphic camera, such revolving principle having been effected and used in England
prior to November 1885.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
In a photographic camera that has the adapter or sensitive plate holder
constructed so as to revolve, for the purpose of placing the sensitive plate in either
a vertical or a horizontal position, the method of attching the said adapter to the
camera body by means of grooved and flanged parts, marked respectively c, d
and d or d on accompanying drawing, fitted to or forming part or parts of a
camera body and adapter, and operated in the manner and for the purpose as
herein before described.
