NEW OR IMPROVED SUSTAINERS FOR SASHES, DOORS, SLUICES, AND OTHER SIMILAR SLIDING BODIES
Year: 1873

page_text: LETTERS PATENT to Charles Hodgson, of Middlesbrough, in the
County of York, Pattern Maker, for the Invention of "NEW OR
IMPROVED SUSTAINERS FOR SASHES, DOORS, SLUICES, AND OTHER SIMILAR
SLIDING BODIES."
Sealed the 14th October 1873, and dated the 23rd July 1873.
PROVISIONAL SPECIFICATION left by the said Charles Hodgson at the
Office of the Commissioners of Patents, with his Petition, on the
23rd July 1873.
I; CHARLES HODGSON, of Middlesbrough, in the County of York,
Pattern Maker, do hereby declare the nature of the said Invention for
"NEW OR IMPROVED SUSTAINERS FOR SASHES, DOORS, SLUICES, AND OTHER SIMILAR
SLIDING BODIES," to be as follows:-
The object of this Invention is to hold and sustain sashes, doors,
sluices, and the like, which slide up and down or "to and fro " in frames,
grooves, or other openings, in any required position, and thus entirely to
supercede the present complicated, inconvenient, and costly arrangement
of box or hollow frames, suspending cords, and balance weights.

page_text: The means by which I propose to effect the said object of my present
Invention are as follows:-In the case of a sliding sash, door, or sluice
I securely fix curved steel springs or india-rubber cushions in the groove
in the inside of the outer frame, or they may be fixed in a groove in the
sash, sluice, or door when convenient. Three or more, if desired, of
these steel springs or cushions are permanently fixed in the said grooves
by means of a screw or pin, that is, three such springs for each bead or
bar. The said springs or cushions are equally suited for working sashes,
doors, and sluices either vertically or horizontally, so as to act as a
cushion to such sash, door, or sluice, and to press against it with suffi-
cient force to hold it securely in any desired position, without the aid of
suspending cords and balance weights. In order that the sash may work
or run more easily and truly I attach pullies or grooved wheels or rollers
at or near the four corners thereof, which pullies run upon or against a
strip or bead of wood or other suitable material fitted in the grooves of
the outer frames.
As an additional security to sustain the sash in the open or partially
open position desired I attach to the lower parts thereof a spring
catch, which entirely prevents such sash from moving downwards.
I also provide a screw or a spring fastener to secure the sash when
closed.
It will thus be seen that by my improved elastic steel spring or
india-rubber cushion, sustainers, and arrangements, sashes and other
similar sliding bodies or constructions can be securely held in any open
or partially open position, without the aid of box frames, cords, and
suspending or balance weights, and at the same time work both easily
and truly in their respective grooves or other openings.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of July, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Hodgson, Her special licence that I, the
said Charles Hodgson, my executors, administrators, and assigns, or such
others as I, the said Charles Hodgson, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United King.
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for " NEw or Improved Sustainers for SASHES, DOORS,
SLUICES, AND OTHER SIMILAR SLIDING BODIES," upon the condition (amongst
others) that I, the said Charles Hodgson, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters

page_text: run more easily and truly. The said sustainers may be fixed in a groove
in the sash frame when convenient. Also, instead of the pulley or
grooved wheel, a wheel or roller with a convex periphery may be used to
work in a grooved or fluted strip of wood or metal placed in front of the
sustainers in the place of the projecting bead 6.
In Figure 2 a¹ is an alternative india-rubber sustainer fixed or
secured in the sash frame; and 63 a corrugated strip of wood or metal to
hold the said india-rubber in place.
For securing the sashes when closed I fix a cranked lever or tongue e
in a slot or frame f, sunk in the lower portions of the side styles of the
upper sash.
The lever or tongue e is turned or operated by the knob or
handle g, so as to engage in the neck of the catch h, fixed to the upper
style of the lower sash when the two (upper and lower) sashes are
fastened or secured together. To unfasten or free the said sashes from
each other the lever e is simply turned up by the handle g clear of the
catch h.
My improved sustainers are equally suited to sashes, doors, sluices,
covers, and the like, fixed horizontally, or at any angular inclination,
and so placed as to act thereon as herein-before described for vertical
sliding sashes.
It will thus be seen that by my improved spring or elastic sustainers and
general arrangement, sashes, and other similar sliding bodies or construc-
tions can be securely held in any open or partially open position without
the aid of box frames, cords, and suspending or balance weights, and at
the same time work both easily and truly in their respective grooves or
other channels or openings.
Having thus fully described and explained the nature of my said
Invention, and the method of performing the same, I desire it to be
understood that I do not confine myself to the precise dimensions or
form, or to the material of the suspenders now illustrated, because they
may be differently formed, for instance, as shewn in Figures 6 and 7 ;
and they may also be made of india-rubber or other suitable elastic
substance, as shewn in Figure 2ª; neither do I confine myself to the
dimensions or positions of the several other parts of my arrangement for
sliding sashes and other sliding bodies; but I claim as my Invention, and
desire to secure by the before-mentioned in part recited Letters Patent,
the use of lateral spring or elastic sustainers, and the general arrange-

page_text: ment of parts substantially as and for the purposes herein described and
shewn in the Drawing.
In witness whereof, I, the said Charles Hodgson, have hereunto set
my hand and seal, this Twenty-eighth day of October, in the year of
our Lord One thousand eight hundred and seventy-three.
