WILLIAM JACKSON BLEASE, No. 11, Stamford Arcade, Ashton-under-Lyne,
Lancashire, Painter and Decorator, JAMES HENRY WOOLLEY, 62, Market Street,
Stalybridge, Lancashire, Painter and Decorator, do hereby declare the nature of
this invention to be as follows: :-
(1) The object of this invention is to form a strong and firm trestle which when
not in use can be folded up in small compass parallel to each other and put away.
(2) It consists of four legs and a cross bar; for light work the legs are about
3 ft. 4 inch in length and the crossbar 2 ft. 3 inch in length.
.
(3) Each pair of legs is then taken and rivetted together at the centres (to form
two crosses) with two ordinary rivetts. The rivetts are left easy to allow the bars
of the legs to slide paralell to each other.
(4) The crosses of the legs are then placed upright (opened out) and the crossbar
inserted between both pairs of legs at one end, and fastened with a rivet passing
through one end of each pair of legs, and through one end of the crossbar between
them, at a distance of about 1/2 an inch from the ends of legs and crossbar.
(5) The rivett which runs through the ends of the legs and crossbar is not straight
but is strained in the centre, and the crossbar is chamfered for about 2 inch at
the same end on the top sides to allow the legs to fit to bevel when stretched out
by the catch mentioned in paragraph (7).
(6) The crossbar at the other end is supported between the tops of the two remain-
ing legs, by being hollowed out on each side to form two sockets, 1 inch in diameter
each about two inches from the end of crossbar, the legs being held in position
by an hinge formed out of rolled flat steel or other metal, riveted by a single
rivet the said hinge being screwed on the two legs about 3 inches below where
the ends of the two legs fit into the sockets on the crossbar.
(7) Lower down the pair of legs where the hinge mentioned in par. (6) fits on and
about 3 inches from centre of same is placed a piece of sheet steel or other metal.
about 7 inches long and 1, an inch in width with a screw-hole at one end and
a small slot at the other end; this is screwed to one pair of legs at one side
and slotted on an ordinary screw placed on the other pair of legs. The object of
this catch is to secure and fix firmly the ends of the legs in the sockets on the
crossbar, and give rigidity to the trestle by straining out the legs which takes
place when the slot is hooked on the screw head.
(8) When not in use loose the catch, lift up the crossbar at the end where sockets
are, slide the legs together, the crossbar forming the centre piece.

WILLIAM JACKSON BLEASE, 11, Stamford Arcade, Ashton-under-Lyne, Lancashire,
Painter and Decorator, and JAMES HENRY WOOLLEY, 121, Cotton Street, Ashton-
under-Lyne, Lancashire, Painter and Decorator, late of 62, Market Street, Staly-
bridge, 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:-
(1) The object of this invention is to form a strong and firm trestle which when
not in use can be folded up in a small compass and put away.
(2) It consists of four legs A A A A and a crossbar B Fig. (1) for light work the
legs are about 3 ft. 4 in. long and the crossbar 2 ft. 3 in. in length.
(3) Each pair if legs is then taken and rivetted together in the centre (to form
two crosses) with two ordinary rivetts c Fig. (1).
The rivetts are left easy to allow the bars of the legs to slide paralell to each
other.
(4) The crosses of the legs are then placed upright close together and the crossbar
inserted between both pair of legs at one end, and fastened with a rivett R. Fig. (1)
passing through one end of each pair of legs and through one end of the crossbar B
between them at a distance of about half an inch from the ends of the legs and
crossbar.
(5) The rivet R which runs through the ends of the legs and crossbar is not
straight but is strained in the centre see R Fig. (3) and the crossbar at the same
end is chamfered for about two inches on the top sides see D Fig. (3) to allow
the legs to fit to bevel when stretched out by the catch K Fig. (2) described in
par. (7).
(6) The other end of the crossbar is supported between the tops of the two remain-
ing legs by being hollowed out on each side to form two sockets S Fig. (1) one inch in
diameter each at a distance of about 3 inches from the end of crossbar, the legs
being held in position by an hinge H Figs. (1) (2) (3) formed out of rolled flat steel
or other metal, rivetted by a single rivett the said hinge being screwed on the legs
about three inches below where the ends of the two legs fit into the sockets S
Fig. (1) of the crossbar.
(7) Lower down the legs where the hinge H is screwed on and about three inches
from centre of legs on the inside is placed a piece of sheet steel or other metal
about seven and a half inches long and half an inch in width see dotted lines
Fig. (1) and K (Fig. (2) with a screw hole at one end and a small slot at the other
end, this is screwed to one pair of legs on the inside and slotted on an ordinary
screw placed on the inside edge of the other pair of legs. The object of this
catch K is to secure and fix firmly the ends of the legs in the sockets on the cross-
bar see B Fig. (2) and give rigidity to the trestle by straining out the legs, which
takes place when the slot is 'hooked on the screwhead aforesaid.
(8) When not in use loose the catch K lift up the crossbar B at the ends where the
sockets are, slide the legs together the crossbar forming the centre-piece B Fig. (3).
(9) Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1
A combination of the following features of novelty

page_text: (b) The chamfer on crossbar 1) Fig. (3).
(c) The sockets on crossbar S Fig. (1).
(d) The rivetted hinge on legs H Fig. (1) (2) (3).
(e) The catch on legs K Fig. (2).
