I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. 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 to devices employed for supporting and adjusting the inclina-
tion of the heads or ends of sofas and lounges which are pivotted to drop from a
vertical to a horizontal position which is accomplished by the use of pivotted latch bars
racks and cams combined with a head frame fitted to swing on the inain frame of the
lounge or sofa.
Referring to the drawings of which Figure 1 is a vertical longitudinal section of one
end of a lounge fitted with this invention.
Figure 2 is a sectional view on line xx Fig. 1 showing for effect, one of the latch
bars forced away from the teeth of segment.
A represents the lounge with the side rails a, and end rails b.
B represents the pivoted head rest, consisting of upright pieces d and cross pieces e.
To the inner side of the upright & is fastened the metallic plate E carrying the pivot
pins e¹ which enters a socket e² in a plate fattached to the rail a. This plate has cast
on to it the segmental rack R with notches
'
I is a latch har pivoted on to plate E at The lower end of this bar extends to
below the segmental plate R, and the upper end extends up to the shaft h which passes
through a hole in the same. This latch bar is forced outward by a spring K, which
forces inward the lower end of the said latch bar against the seginental plate R.
On to the shaft h is a cam i-Now by turning the said shaft either by knobs P on
the end or by an arm S attached to the center thereof, the cam will force out tho
upper end of the latch bar, and release the lower end thereof from off the teeth of the
segmental plate R. When this takes place the head B of the loungo can be turned
down, as shown in dotted lines Fig. 1. By releasing the cam from off the latch bar

page_text: the lower end of the same can be made to catch into any of the notches of the
segmental plate, and thus hold the head B in any desired position.
Both ends of the head piece B can be provided with latch, segment, &c., if so
desired.
The parts can be made of metal or part métal and wood.
Having now particularly described and ascertained the nature of the said invention
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
1st. The combination of the quadrental ratchet plate R having the central pivot
socket and neck with the latch I and the cam shaft and cam i substantially as and for
the purpose specified.
2nd. In combination with the adjustable head of a lounge or sofa, duplicate
quadrantal ratchet plates R, R, latch plates and latches E I and cans ii substantially
as set forth.
3rd. As a new manufacture, the quadrental plate R, and latch plate and attached
latch for the purpose set forth.
4th. The combination with the head B adapted to swing on the main frame of the
end-bent spring bar or bars I fulcrumed on the inner sides of plates E the quadrant R,
constructed as described and the shaft carrying cams in contact with the upper ends
of said latch bars, as and for the purpose specified.
Dated this 4th day of March 1887.
