A joint stay designed to keep open and maintain heavy hinged articles or parts
thereof being a stay consisting of two pieces of metal of equal or unequal length
joined together with a hinge and having a spring on the back or outer side of one
piece of the stay overlapping the said hinge of the stay and a knuckle made of
metal on the back or outerside of the other piece of the stay at the extreme end
of such piece where so hinged as aforesaid but not overlapping such hinge. The
knuckle acting as a stop to bring the spring into play. Each of the pieces at the
extreme opposite ends thereof has a hinge or knuckle joint for the purpose of
fixing the stay to the articles or parts thereof in connection with which it is to be
used. The joint stay when opened so as to be at its full length is prevented from
proceeding or receding by the joint action of the spring and knuckle and can only
be closed by pressing the stay on the front or inner side.

Improvements in Stays for Hinged and Pivoted Articles.
I, WENCESLAS JOSEPH HAYSMAN, of 237 Victoria Park Road, in the County
of Middlesex, Cabinet Manufacturer, do hereby declare the nature of my said
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to say :-
This invention relates to jointed stays intended to keep open or to maintain in
position hinged or pivoted articles, and the invention consists of arrangements
illustrated in the accompanying sheet of drawings in which Figure 1 is a side view
of a jointed stay constructed in accordance with my invention and applied to a
hinged bracket for example, the stay being shown in the opened-out position ;
Figure 2 is a side view of the same, the stay being shown in the closed-up
position, and Figure 3 is a plan view of the bracket, showing the stay (in dotted
lines) in the opened-out position.
A represents the bracket or other article hinged to the part A', and B B¹
represents the jointed stay intended to support the bracket A in the raised position
as shown in Figure 1. The pieces B B¹, composing the stay, may be of metal or
other suitable material, and of equal or unequal lengths, hinged together at C.
The other ends of the pieces B B are hinged respectively in the usual way to the
bracket A and to the part A' to which the said bracket is hinged. One of the
pieces forming the stay, that marked B' for example, is formed with, or has fixed
thereto, a stop-piece B2. D is a spring secured at one end to the other piece B of
the stay and bearing at its other end against the stop piece B2 of the piece B¹.
It will now be understood that when the stay is opened out, as in Figure 1, the
stop-picce B2 on the piece B' prevents the piece B from turning on the hinge C in
the direction of the plain arrow beyond the position forming a right line with the
piece B, as shown in Figure 1, while the free end of the spring D bears against the
outer face of the stop piece B2 and prevents the stay from folding inwards, thus
enabling the latter to support the bracket A in the open or raised position as

page_text: shown. When it is desired to lower the bracket A pressure is applied to the stay
at or in the neighbourhood of the joint C in the direction of the feathered arrow
so as to overcome the resistance of the spring D, and the stay can then be folded
or closed into the position shown in Figure 2.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a jointed stay the combination with the folding joint thereof of a stop-piece
and spring arranged and acting substantially as hereinbefore described, and
illustrated in the drawings.
