follows:-
More
This my invention relates to improvements in photographic cameras.
especially to the front portion of cameras, to facilitate the working of this portion
when used with shutter, shutters, or otherwise, which I accomplish in the hereafter
manner by which method the front, shutter, or shutters of the camera can be raised,
lowered or swung to any angle or position desired. place & fix on the camera one,
or more pieces of metal of such a shape as to allow the front to close flat into the
base or tailboard of the camera, the said pieces of metal which holds the shutter,
shutters, or front of camera, I fix into position with one or more thumb screws, to
the bolt or nut of these screws I fix a small screw to the present bolt or nut, to
prevent the nut falling off or unscrewing during use, the mode I adopt for making
the said screw or bolt, is, I first insert a screw or bolt in the usual manner,
the same
screw or bolt I bore hollow & tap inside & outside a screw or bolt, then I screw a
nut on the top portion to bind the shutter, shutters, front or any portion of camera.
I then fix to the said screw or bolt, a screw to prevent the nut from falling or un-
screwing off.

Improvements in Photographic Cameras.
I, CHARLES HOWELL, of 30, Ladypool Road, Birmingham, in the County of
Warwick, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention consists as hereinafter described of improvements in photographic
cameras and has for its object to facilitate the movement of the front portion of the
camera carrying the shutter or shutters.
In order to enable my invention being clearly understood I will describe it by
reference to the accompanying drawings of which :-
Figure illustrates the base portion of a camera, Figure 2 being an end view
of the same.
Figure 3 illustrates the working of the camera to any desired position.
Figures 4, 5, 6, 7, 8, 9 and 10 are detail views.

page_text: On each side of the front of the camera I screw the brass plates A, A, containing
the grooved channels B, B.
To the pivotted support N I connect the plate M which is free to move on the
axis O by which it is connected.
The support N is also free to move on the axis which secures it to the base
part D of the camera.
The plate M. is clamped in any desired position to the front K of the camera by
means of the screw and slot arrangement G, H. By this arrangement the camera
can be adjusted to any desired position, or closed up as shown in Figures 1 and 2,
the hinged support N allowing the part K to close flat behind the base D.
To the plate Ma catch P is fixed so that it may be held to the base frame A by
tightening the thumb screw H¹.
When desired I may use two plates M instead of the one aforesaid.
The part K can by this arrangement be raised, lowered, or swung to any angle or
position desired.
The brass pegs F, F, are fixed to the different parts of the camera as shown in
the drawings, being screwed externally and internally. Over these pegs I screw
the thrumb screws G, G, and in order to prevent them falling or screwing off I screw
into their extremities the screw pins H, H.
When the camera is adjusted to a desired position the thumb screws G G are
screwed up thus keeping it fixed in the required position Figures 6 and 7 shown
the thumb screw drawn to an enlarged scale.
Figures 4 and 5 represent the screw pin and peg into which it is screwed.
Figures 8 and 9 show my invention drawn to an enlarged scale where the thumb
screw G, takes bearing against the hinges C, C, thus keeping the camera firm.
In Figure 10 the metal part is shown of such a shape as to allow the camera to
be closed or adjusted.
The arrangement herein described whereby the thumb screws are prevented from
becoming unscrewed off the pegs by means of the screw nuts H may be adapted to
any apparatus where such thumb screws are needed.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1. The improvements in photographic cameras consisting of the pegs FF over
which are screwed the thumb screws G G being kept from unscrewing off by means
of the screwpins H, H, whereby a photographic camera may be readily adjusted.
2. The means of adjusting a photographic camera by the metal plate or plates M,
hinged to the support N which allow the camera to be adjusted substantially as
described and illustrated in the accompanying drawings.
