PROVISIONAL SPECIFICATION.
A New Apparatus for the Connection of the Fronts and Backs of
Cameras, Stereoscopes, Graphoscopes; and the like.
JOSEPH DAY of Scout Hill View, Dewsbury, in the County of York, Cloth
Drawer, do hereby declare the nature of this invention to be as follows:-
This invention consists in a new method of connecting the fronts, and backs of
cameras. stereoscopes, and graphoscopes, by means of "lazy tongs," either employed
singly, or in various combinations, enabling the same to be readily extended, and
contracted, making them more portable when not in use, and in a self-adjusting
view carrier, or support for the picture for the stereoscopes, graphoscopes, and the
like. I do not limit myself to the use of any particular number of links of the
'lazy tongs," but I may prefer to make the stereoscopes, and graphoscopes, with
the self-adjusting view carrier, as seen from the under side when fully extended,
as shown in the accompanying drawing which also shews how the " lazy tongs
may be applied to the cameras and the like.
"
The working of the apparatus may be described with reference to the accom-
panying drawing as follows.
H, is the usual front or eyepeice to which is secured a sheave or guide F, to
which is attached the "lazy tongs "G G¹ one end of each A A' being limited to
a rotatory motion around the revits or studs a a' while the ends B B have revits
or studs secured to their ends which slide in the slotts b 6' on the expansion or
contraction of the "lazy tongs"; of the other ends of the tongs C C, D D' are
attached to the self-adjusting view. carrier, which consists of a sheave E and the
ends K K'. The ends C C³ are secured to the sheave E by revits or studs c c¹ and
are limited to a rotatory motion around the said revits or studs. To the ends D D¹
are secured the ends K K', and the revits or studds which work in the
slotts d d and carry with them the ends K K', through the ends K K₁ slotts
are cut through which the revits or studs c c pass, and which bind the ends to a
motion parallel to the sheave E.
The action is as follows, on the extension of the "lazy tongs" contraction of the
ends take place, of the ends A. B, A' B', B B' slide in the slotts bb, of the other
ends C D, 'C' D', to the ends C C' are secured to sheave by revits or studs c c¹
but can rotate about them, while the ends D D₁ to which are secured the ends
of K K¹ move towards C C' extending the adjustable carrier to a suitable length.

5 A New Apparatus for the Connection of the Fronts and Backs of
Cameras, Stereoscopes, Graphoscopes, and the like.
I, JOSEPH DAY of Scout Hill View, Dewsbury in the County of York,
Cloth Drawer, 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
0 the following statement :-
This invention, consists in a new method of connecting the fronts and backs of
cameras stereoscopes and graphoscopes, by means of "lazy tongs " and in a self
adjusting view carrier, or support for the picture, for the stereoscope graphoscope

page_text: and the like. I do not limit myself to the use of any particular number of links of
the "lazy-tongs" but prefer to make the stereoscope and graphoscope, with the
self-adjusting view carrier, as illustrated in the accompanying drawings.
His the front or eyepeice made of stamped and pierced metal to which is
attached the "lazy-tongs " G G one end of each A A¹ being limited to a rotatory
motion around the revits or studs a¹ a while the ends B¹ B move in the slotts b¹ b to
permit of expansion and contraction of the ends of the "lazy-tongs." Of the other
ends C¹ D' C D they are attached to the sheave E in which the view-carriers K' K
are fitted. The ends C¹ C are secured to the sheave by means of revits or
studs cc while the ends D¹ D are secured to the view-carriers and sheave by revits
or studs which slide in the slotts d'd in the sheave E.
The view carriers K' K are also fitted to sheave E and have slotts through
which pass the studs cc which provide. for the longitudinal extension of
carriers K K to which are fitted the ends of "lazy-tongs" D' D by the revits or
studs which slide in the slotts d' d.
The action is as follows on the extension of the "lazy-tongs" G¹ G the
ends A¹ A rotate around the revits or studs a' a the ends B B move in the
slottsband carry with them the revits or studs towards A' A. The ends C¹ C
rotate around the revits or studs c'e while the ends D' D move in the slotts d' d
towards CC carrying with them the studs and view carriers K' K which have
slotts in them to provide for the longitudinal extension of the carriers K¹ K through
which pass the studs or revits e¹ c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The use of "lazy-tongs" for connecting the fronts and backs of cameras,
stereoscopes, graphoscopes and the like, as may be required for maintaining the
same at various distances from each other substantially as herein shown and
described.
2. A self-adjusting view carrier for stereoscope graphoscope, and the like
substantially as shown and described and for the purpose specified.
