Improvements in Satchel Frames.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co., Patent Agents,
15 Southampton Buildings in the County of Middlesex, 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 :-
This invention relates more particularly to the hinge portion of the frame, the
object being to cause the hinge, when the frame is opened to its fullest extent, or
otherwise, to automatically lock and hold itself in such position until the locking
mechanism is released.
The invention consists in the improved hinge for satchel-frames and in the
arrangement and combination of the several parts thereof and with the said frame,
as herein set forth and finally pointed out in the claim.
Referring to the accompanying drawing, in which similar letters of reference
indicate corresponding parts in each of the several figures where they occur,
Figure 1, represents, in elevation, a satchel-frame and a hinge connected there-
with embodying my invention..
Figure 2, represents, in an end elevation, the frame and hinge wide open, the
frame being broken off near the hinge.
Figure 3, represents a similar view of the hinge detached from the frame and
looking at it from the opposite side to that shown in Figure 2.
Figure 4, represents partially in plan, the hinge wide open the central portion,
or working parts being shown in section taken through line a.
Figures 5, 6 & 7 are detail views of the working parts.
In said drawing, a, indicates the satchel-frame which is of the ordinary con-
struction and therefore needs no description; b, indicates the leaves of the hinges,
which are connected to or with the frame in the ordinary manner.
The portions or sides, c and d, of the knuckle or joint of the hinge are united by
and work upon a hollow or tubular pintle, e, the ends of which are turned outward
or clinched upon the countersunk surfaces of the knuckle to prevent the parts from
separating, as will be understood upon reference to the drawing, more particularly
to Figure 4, in which said pintle, e, is shown by the heavy black or solid lines.
Said pintle is also shown in end view and elevation, in Figure 7.
Passing through said tubular pintle and working longitudinally therein is a push-
rod, f, upon one end of which is secured a cross-head or bar g, which fits into a
groove or recess, g¹, Figures 3, 4 & 5, in one side of the knuckle and carries one or
more (in the present case two) inwardly-projecting pins, h, which fit and work into
corresponding apertures, h¹, formed in the opposite sides of the knuckle, as indicated
in said Figure 4. Said cross-head or bar is also shown in plan and elevation, in
Figure 6.
Said apertures, h¹, are so arranged in the opposite sides of the knuckle as that
they coincide with one another only when the frame or hinge is fully opened, when
the pins, h, under pressure of a spring, i, automatically enter the apertures in the
side, d, thereby locking and holding the hinge open until the pins are forced out
again by pressing upon the head, f, of the push-rod, as will be readily understood.
upon reference to said Figure 4.
Said spring is located in a socketed head or washer j, through which the push-
rod also, passes, and bears against the bottom of said socket and the base of the
head, f, of said push-rod, as indicated in said Figure 4. In closing the frame or

page_text: hinge the pins, upon being pushed back, as described, ride upon the inner surface
of the side or part, d, as will be understood.
I have shown herein my self locking hinge attached to one end only of the
frame, which in ordinary practice is sufficient, though it may be applied to both
ends if desired.
I do not limit myself to the specific construction, herein shown, of the several
parts as it is manifest that the same may be varied to a certain extent without
departing from the spirit of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent I declare that what I claim is :-
1. In a hinge for a satchel-frame, the construction with the leaves having
perforations arranged parallel with the central or hinge-perforation, of a tubular
pintle through the central opening of the leaves, a spring actuated push-rod
arranged in said tubular pintle and means in connection with said push-rod for
engaging with the holes in the leaves and locking the hinge, as described and for
the purposes set forth.
Dated this 26th day of April 1892.
