WILLIAM BENDALL of 133 Vicarage Road, Aston in the County of Warwick
Cabbinett Maker do hereby declare the nature of my invention for THE IMPROVE-
MENTS IN THE MANUFACTURE OF SWINGING AND SUPPORTING MOVEMENTS FOR
ARTICLES USED IN SCHOOLS & HOUSEHOLDS to be as follows:-
Consists in useing in the construction of furniture, that is required to move
backwards or-forwards, or pulled up or down, as maps, blinds, black boards, and
all kinds of swing glasses, a threaded bolt with round. or square neck. The
bearer to be a slotted plate to fit the neck of the bolt. The article to be supported
to have a nut fixed to it. Between the bearer & the nut is placed an eliptic or
spiral spring, or washers of leather, rubber, wood, or metal, The article to be
supported is screwed up to the tention required to make it self supporting in any
position a second or lock nut is now screwed up to the first which will keep the
tention from any alteration.
In small articles. the nuts may be dispenced with and the spring only used.
It shall make no difference wether the beareing plates be screwed upon the article
swung or upon the supports.
By blinds, are meant Venetian blinds as they are collected on a rooler as other
blinds The tention can be released by a leaver attached to the bearer pin allowing
the articl to decend by its own weight. This furniture can be stamped in steel,.
being lighter and stronger & fixed to the roolers by a centre screw.

page_text: I WILLIAM BENDALL of 133 Vicarage Road Aston near Birmingham in the
County, of Warwick Cabinet Maker, do hereby declare the nature of my said
invention for AN IMPROVED ADJUSTMENT OR SUPPORT FOR SWINGING FRAMES
APPLICABLE ALSO FOR BLINDS MAPS AND OTHER SIMILAR ARTICLES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the drawings hereunto
annexed and to the letters and figures marked thereon i
This invention consists in the construction of furniture for the adjustment or
support of swinging frames or for the action of pulling up or down as for maps
blinds or other similar articles as follows.
"
j
A threaded bolt with a round or square neck fitting in a bearer, the bearer
being a slotted plate fitting the neck of the bolt the article to be supported having
a nut fixed upon it. Between the bearer and the nut is placed a spring elliptic
or spiral or washers of leather india rubber wood metal or other suitable material.
The article to be swung being screwed up to the tension required to make it
self supporting in any position. A second or lock nut is now, screwed up to the
first which will keep the tension from altering..
In small articles the nuts may be dispensed with. The bearing plate may be
fixed upon the article to be swung or upon the standards.
This arrangement is also applicable to Venetian blinds the cords being gathered
on a similar roller to those used for roller blinds or maps.
When applied to blinds the tension can be released by means of a lever attached
to the pin enabling the article supported to run down by its own weight?
This furniture may be stamped out of steel as being lighter and stronger and is
fixed, by a central screw,
Referring to the drawings Fig 1 shews the threaded bolt (A A¹) with a square
neck passing through a standard (B) with the head (A) formed to fit into a slotted
plate (C) upon the side of a looking glass or other article the nut (D), being placed
at the back of the standard (B). Between the bearer, and the standard is placed
the elliptical spring (E) or a spiral or other spring may be employed placed within
the nut. The second or lock nut (D¹) is then screwed. up to the first nut D or this
second or lock uut (D') may be dispensed with by squaring the end of the threaded
bolt (A) and placing thereon a square washer thus removing the friction of the
nut in turning.
.
;
Fig 2 illustrates in front view and Fig 2A in section the adjustment to be used
where a pin or bolt passing through the standard cannot be used, in which (a) is

page_text: a stamped steel cup with a steel spring cover (b) through which passes the
supporting bolt (c) over which catches the slotted plate upon the looking glass as
at (C) Fig 1. The supporting bolt (c) is screwed up from the back of the cup by
a nut and washer (d d¹). Upon the pin is fitted a drum (e) fitting into the cup (a).
the drum standing slightly above the cup (a) receives pressure from the spring
cap (b) and keeps it constantly up to its bearing.
An adjustable steel band (f) is placed round this drum which is screwed up
by means of a fly nut (g) for the purpose of firmly securing heavy frames in any
required position.

Fig 3 illustrates an arrangement for swinging the frames from the side in which
I use a description of of knuckle hinge. I form the one portion (G) of the plate
which is attached to the standard of a V shape with the knuckle on the inside as
shewn at (H) and I form the knuckle (I) on the flat plate (J) and pass the
knuckle (1) through the slot (K) in the other plate. The spring (E) bearing
against the knuckle (H) and pressing it against the knuckle (I). It may be tightened
up to any required pressure by means of the threaded pin and two lock nuts (D D¹)
as before described for Fig 1.
The same principle may be applied to an ordinary outside knuckle hinge or the
knuckle can be made hollow and spiral springs placed inside.
Fig 4 illustrates the principle as applied to blinds or maps in which the threaded
pin is fitted upon a bracket with the spring (E) placed at the back and the
adjusting nuts (D D¹) as shewn.
When I require to releave the tension so as to enable the blind or map to run
down of its own weiglit I employ an arrangement similar to that illustrated in
Figures 5 and 5^ in which the pin A with its spring and nuts revolves freely in the
bracket (L), (M) is a sliding clip clipping a collar upon the pin and kept up to its
grip or bite by the spring (N) thus only allowing of the pin to revolve when the
blind is pulled from the centre, (O) is a lever carrying a small pully (P) over which
the cord passes onto the roller end so that by pulling the cord the lever raises
the clip and leaves the blind or map free to be wound or to fall, by its own
weight.
In some instances for Venetian or other blinds the tension spring (E) may be
dispensed with or as for instance in "Scotch furniture "the tension spring (E) may
be placed on the roller end instead of on the bracket piece.
Fig 6 shews the stamped steel blind furniture which being stamped with the
edges (Q) turned inwards or cupped as shewn forms a guide for the cord and
strengthens the blind end.,
I do not confine myself to this particular section of blind'end. For Venetian
blinds spools of the form of Fig 6 are placed upon a roller each to collect 'one of
the supporting cords.
Fig 7. is a section through a blind roller shewing another form of bracket
working out the same principle for blinds or maps.
The spring (E) keeping the pulley (R) up to its bearing against the roller (S)
and holding the cord (T) tightly until it is released by pulling the cord (T¹) so as
to pull down the spring (E). The tension of this spring (E) is adjusted by means
of the screw pin (A) placed in the main body of the spring which being tightened
or screwed up enables the strength of the spring to be adjusted to the required
weight which it is intended to carry.
$
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
'
Firstly. The adjustment or support of swinging frames by the application of
furniture consisting of the several parts namely the threaded bolt with a spring
adjusted by the nuts and washers substantially as herein set forth and specified
°

page_text: and the application of the said adjustment in connection with the actions for
pulling up and down maps blinds and similar articles.
Secondly. The stamping out of steel such portions of the furniture as the
cup Fig 24 and spool or blind roller end Fig 6. as herein set forth and specified.
