Republic of France, Guilder, for the Invention of "IMPROVEMENTS IN SLIDING
PICTURE FRAMES."

"
The object of this Invention is to provide artists and picture dealers with a
temporary frame for pictures varying in dimensions; with this view the sides and
ends of the frame are made to slide so that it can be lengthened, widened, or
shortened as desired to fit any sized picture.
The frame is composed of eight pieces forming four plain and four hollow parts,
these latter sliding in grooves cover the former; by this method of construction the
frame is easily increased or decreased by drawing out or pushing in the sides or ends
parallel with one another or working telescope fashion.
For very large pictures a rack and pinion worked by handle is employed so that
the sides or ends may be equally drawn without strain.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Léon Benjamin Souty in the Great Seal Patent Office on the 7th
May 1877.

these latter slide in grooves and cover the former; by this method of construction
the frame is easily increased by drawing out or pushing in the sides or ends parallel
with one another or working telescope fashion.
For very large pictures a rack and pinion worked by handle is employed so that
the sides or ends may be equally drawn without strain.
In the accompanying Drawings,-
Figs. 1 and 2 represent a frame constructed on the principle above described. In
these two Figures the reverse of the frame is shown and closed.
Figures 3 and 4 represent the frame open and held in the slides by means of nut
screws.
Figures 5 and 6 represent a frame front view and closed.
Figure 7 shows one of the four plain parts; Fig. 8, one of the hollow parts
mounted on its slide.
Figures 9 and 10 represent the frame open and front view.
Figure 11 shows the rack in detail which is employed for large pictures, so that
the parts may be drawn out perfectly parallel and to keep the frame in true form,
which it would not otherwise be.
Fig. 12 shows the manner of adapting the rack to the frame; and Figures 13
and 14 represent details of the rack.
From the foregoing remarks it will be observed that the main feature of the
Invention is the construction of a frame capable of increase or decrease in its
dimensions for the purpose of rendering it adaptable to pictures of various sizes
and so form a temporary frame for the studio or for dealers, such capacity of
variation of size being effected by the construction of the frame into eight
parts, four of which move on slides and are hollow, whilst the others are plain
and are covered by the hollow ones, so that the external appearance of the frame is
symmetrical.
What I claim therefore and desire to secure by Letters Patent is the construction.
of picture frames based on this principle in the manner and for the purposes herein
mentioned.
In witness whereof, I, the said Léon Benjamin Souty, have hereunto set my
hand and seal, this Second day of May, in the year of our Lord One.
thousand eight hundred and seventy-seven.
