We MARIUS PANON and EDWARD GRENET of No. 3. Rue Torricelli, Paris in the
French Republic do hereby declare the nature of our invention to be as follows :-
Our Invention relates to an improved clamping device by means of which the inner or
stretching frame of oil paintings, engravings and other pictures may be readily secured
to and removed from the main or outer frame without the aid of nails or screws
hitherto used for that purpose.
Figure 1. of the accompanying drawing is a plan view of an improved clamp.
Figure 2. represents the maintaining stud.
Figure 3. represents the clamp in position.
a. is a plate in which is pivoted a metallic spring b. curved at c. in the free end of
which is cut a longitudinal slot d.
e. is the maintaining stud composed of two parts one of which forming the head is
tapped at and the other corresponding therewith threaded in g. is pointed at the
lower end to penetrate into the wood of the stretching frame. The plate a. is secured
to the back of the main frame i by screws passing through the holes h. h. fig. 1. as
shewn in fig. 3.
The point g. of the maintaining stud is screwed into the inner or stretching frame j.
at a point corresponding with the slot d. of the spring & through which it passes and
the whole is secured by screwing on the threaded part thereof the tapped part f. of
the head e. Two, four or any other number of clamps may be applied to each frame
as required.
When desired, to change the position of the picture in the outer frame the main-
taining stud e. is slackened thus allowing the springs b: to advance or recede in the
slot d. over the set screw y until they reach the point required where they are again
fixed by a reverse turn of the screw head e.
When desired to withdraw altogether the inner or stretching frame the heads of the
studs e. are removed having the points g. in the wood and the springs b. are turned
aside on their pivots over the back of the main frame, the opening of which is thus
left clear.

page_text: We, MARIUS PANON and EDWARD GRENET, of No. 3, Rue Torricelli, Paris, in the
French Republic, 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 :-
Our Invention relates to an improved clamping device by means of which the inner
or stretching frame of oil paintings, engravings and other pictures may be readily
secured to and removed from the main or outer frame without the aid of nails or
screws hitherto used for that purpose.
Figure 1. of the accompanying drawing is a view of an improved clamp.
Figure 2. represents the maintaining stud.
Figure 3. represents the clamp in position.
a. is a plate in which is pivoted a metallic spring b. curved at c., in the free end
of which is cut a longitudinal slot d.; e. is the maintaining stud composed of two
parts, one of which, forming the head, is tapped at f, and the other, corresponding
therewith, threaded in g., is pointed at the lower end to penetrate into the wood of
the stretching frame.
The plate
a. is secured to the back of the main frame i. by screws passing through
the holes h. h., (fig. 1.) as shewn in fig. 3. The point g. of the maintaining stud is
struck or screwed into the inner or stretching frame j. at a point corresponding with
the slot d. of the spring b. through which it passes, and the whole is secured by
screwing on the threaded part thereof the tapped part f. of the head e.
Two, four, or any other number of clamps may be applied to each frame as
required.
When desired to change the position of the picture in the outer frame, the main-
taining stud e. is slackened, thus allowing the spring . to advance or recede in the
slot d. over the set screw g. until they reach the point required, where they are again
fixed by a reverse turn of the screw head e.
When desired to withdraw altogether the inner or stretching frame, the heads of
the studs e. are removed, leaving the points g. in the wood, and the springs b. are
turned aside on their pivots over the back of the main frame, the opening of which is
thus left clear.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim, is:
A clamping device for picture frames composed of a curved metal spring as in b.,
pivoted at one end to the main frame and pressing by the opposite end on the inner
or stretching frame where it is secured by a set screw playing through a slot d. in
combination with a fixed pointed stud y., substantially as and for the purpose set forth
and shewn.
Dated this Ninth day of March 1887.
