page_text: FRANK PROCTOR, of Benington, Stevenage, in the County of Hertford, England,
Engineer, do hereby declare the nature of this invention to be as follows:-
An adjustable Head-rest being an improvement in Chair Fittings, and comprises
a novel attachment whereby a rest for the head is provided at any height and.
position to suit the requirements of the occupant.
:
For this purpose I use preferably one bracket, as shewn at B, Fig. 1 on the
accompanying drawing, which is fitted with a clamp (or clamps) C, for attaching
to the back of a chair, this bracket is formed with a projecting piece fitted with a
lateral slot, through which I pass a bolt A at the head of which is a boss or eye
fitted with a set screw D, which forms the bearing for the headpiece E; the top of
the headpiece I make of a convenient shape to suit the back of the head, & which
I preferably pad with horse hair or other soft material, and the stem I preferably
make in the shape of a round bar of sufficient length to suit any vertical adjustment,
whilst the slot in the bracket together with the eye-bolt, allows for any horizontal
or angular adjustment.
Instead of the eye-bolt I sometimes make the stem of the headpiece fitted with
a slot F, in which case I use an ordinary bolt for fixing the head piece to the
bracket as shewn at a.
In order to facilitate the adjustment of the head rest by the occupant of the
chair I use preferably a spring bolt, instead of the eye or ordinary bolt, as shewn
at ; in this case I corrugate the outer surface of the slotted stem of the head
piece to form a bed for the cross pin p, which I throw out of its seat by means of
a bell crank lever b, which acting on the head of the bolt a, compresses the spring s
by which the cross pin is brought back into its seat as soon as the pressure on the
bell crank is relieved.
Sometimes I use two brackets to clamp on to the sides, or top, of the chair back
on each side of the head rest as shewn substantially in figures 2. & 3: in figure 2

page_text: I make the brackets in the form of horizontal rods G, in which case I provide
bosses H at the ends of the crank or head piece I, through which the bracket rods
pass & to which they are attached preferably by set screws.
In figure 3 I provide slots in the brackets to allow for the vertical adjustment of
the crank or head piece.

COMPLETE SPECIFICATION.
An Adjustable Head-rest, being an Improvement in Chair
Fittings.
I, FRANK PROCTOR, of Stevenage in the County of Herts Engineer 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 and
accompanying drawings:-
My invention has for its object an improved method of making and using
apparatus for varying the height of chair backs to suit the requirements of the
occupants, the construction is such that my invention may be attached to the
backs of all ordinary chairs, and admits of a horizontal, vertical, or radial
adjustment and is especially designed to form a comfortable rest for the head.
In accordance with my said invention I use preferably one bracket as shewn
at B, Fig. 1, on the accompanying drawing, which is fitted with a clamp, or
clamps C, for attaching to the back of a chair, and a bearing, or bearings bb, which
take the stem of the head-rest E, and which I preferably fix at the required
position with a set screw D; to this stem I attach a pad J of suitable shape and
construction to form a rest for the head.
Instead of the bearings b, I sometimes have the bracket formed with a projecting
piece fitted with a lateral slot L, Fig. 2, through which I pass a bolt A at the head
of which is a ring or eye (fitted with a set screw D), which forms the bearing for
the head-piece E.
Instead of the eye-bolt A, I sometimes make. the stem of the head-rest flat and
fitted with a slot in which case I use an ordinary bolt for fixing the head-piece to
the bracket as shewn at a. Figs 2. In order to facilitate the adjustment of the
head-rest by the occupant of the chair, I use preferably a spring bolt or pin,
instead of the eye or ordinary bolt; this I shew at a, Figs 2, and in this case
I corrugate the outer surface of the slotted stem of the head-piece to form a bed

page_text: for the cross pin, this latter I throw out of its seat by means of a bell-crank lever
which acting on the head of the bolt a compresses the spiral springs by which the
cross pin is brought back again into its seat as soon as the pressure on the bell-
crank lever is relieved.
Sometimes I use two brackets G G. Fig. 3, fitted with bolt-bearings n, in which
I fix the ends of a cranked piece H, and between the cheeks of which I attach a
pad J which forms the rest for the head.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is,
1. The method of adjusting an attachment to chairs, which forms a rest to the
bead of the occupant, in any required position, vertically, horizontally, or radially.
2. The construction of the apparatus is such as to allow of its being attached
independently to all ordinary chairs, as hereinbefore described and illustrated by
my drawings.
