I, GEORGE FREDERICK NEWMAN of the firm of William Newman and Sons of
Hospital Street, Birmingham in the County of Warwick, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates primarily to means for adjusting or regulating the tension of
the springs employed in such door hinges, or door spring closing appliances; and
further, the said invention is applicable to both single and double action door and
floor springs, as herein-after described.
I will first describe my invention in connection with a spring butt or hinge,
consisting of top and bottom bearers, with a centrally disposed stay directed in a
midway position between them, and with the flaps which turn outwardly and inwardly,
provided with straps or eyes, which take upon shouldered ends of knuckle barrels,
wherein coiled, pillar, volute or other springs are enclosed.
The springs have their ends directed crosswise, so as to form bars, upon which the
inner forked ends of capped plugs, which move with the flaps, take.
The lower capped or headed plugs are preferably fixed, whilst the upper are
movable, and admit of being turned, when the springs to which they are connected,
require to be adjusted, in tension.
The caps of the plugs have all-through holes, and so have the shanks, through
which latter, pins passing and directed inwardly through the bearer ends, take; so
that by rotating the said cap, and bringing one or other of the holes in the shank
coincident with the holes in the bearers, and then inserting a pin therein, affixes the
springs in their adjusted or regulated positions.
Instead of holes passing through the bearer ends, and shanks of the headed plugs
respectively, 1 make the base of the cap toothed, with the spaces directed vertically,
and coming opposite to a liko upright hole through the hearer; so that on bringing
one or other of the spaces opposite the hole, and dropping a peg within them, the
adjusted tension of the spring is secured after being regulated. Or the base of the
head may be pierced horizontally, wherein the inner end of an obliquely directed pin
which lies within a recess in the bearer, takes.

page_text: In applying my invention to door springs, the regulating means is carried out
essentially in the same way as has been described in respect to a spring hinge.
In applying my invention to a floor spring, a fixed rod passes from the fore part of
the spring casing to the rear, and with its extreme end which is screwed, passing
through a plain hole in the abutment plate, upon which the rear ends of the springs
take their bearings. The end of the screwed rod has a faceted or plain nut, which on
being screwed home, forces inwards the plate, compresses the springs, and gives the
adjustment to them as may be desired.
It will be understood that the rod although described as fixed, moves with the lever,
but is quiescent with respect to the plate.
The affixing of the ends of the springs enclosed within the barrels or knuckles, is
accomplished in various ways, according to the character of the springs employed.
The plug caps as described in the first arrangement, are prevented from rising, or
leaving their socketed ends, by pins or screws taking within an annular groove around
the shank of the plug part.

Improvements in Spring Hinges and other Spring Door Closers.
I, GEORGE FREDERICK NEWMAN of the firm of William Newman and Sons of
Hospital Street, Birmingham in the County of Warwick, Manufacturer, 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 primarily to adjusting means for regulating the tension of
springs employed in door hinges, and door springs.
I will first describe my invention in connection with a spring butt or hinge,
consisting of top and bottom bearers, with a centrally disposed stay directed in a
midway position between them, and with the flaps which turn outwardly and inwardly,
provided with straps or eyes, which take upon shouldered ends of knuckle barrels,
wherein coiled, pillar, volute or other springs are enclosed.
The springs have their ends directed crosswise, so as to form bars, upon which the
inner forked ends of capped plugs, which move with the flaps, take.
The lower capped or headed plugs are preferably fixed, whilst the upper are movable,
and admit of being turned, when the springs to which they are connected, require
their tension to be adjusted.
The caps of the plugs have all-through holes, and so have the shanks, through which
latter, pins passing and directed inwardly through the bearer ends, take; so that by
rotating the said cap, and bringing one or other of the holes in the shank, coincident
with the holes in the bearers, and then inserting a pin therein, affixes the springs in
their adjusted or regulated positions.
In applying my invention to door springs, the regulating means is carried out
essentially in the same way as has been described in respect to a spring hinge.
In applying my invention to floor springs, I connect a rear and a movable spring
abutment plate to a rod, which is moved to and fro by its connection with a bell-
cranked arm, operated by a roller, under the direct influence of the spindle, whose
upper end is provided with a shoe or an attachment strap.
The rear of the rod is screwed, upon which a nut or head takes itself, and by the
screwing up of which, the distance between the spring abutment plates is varied, and
consequently the springs enclosed between them, elongated or pressed accordingly.

page_text: Figure 1 of the accompanying drawings, represents a double-action helical spring-
hinge, constructed and provided with improvements made according to one part of my
invention. One of the knuckles of the said hinge, is shown in longitudinal vertical
section, while the other is represented in elevation.
Figure 2 represents an underside view of the said hinge, with one of the knuckles
in section, in order to exhibit how an adjustment is effected.
Figure 3 represents separately, the right hand flap of the said hinge, and Figure 4
the left hand flap of the same, but with the joint straps shown in section. Figures 5
and 6 represent an end elevation, and also a section of the said right and left hand
flaps, while figure 7 shows a front elevation, of the combined stay and bearers of the
hinge, and figures 8 and 9 represent the knuckle barrels.
Figure 10 shows a single action helical spring hinge, provided with adjusting means
alike unto that of figure 1, whilst figures 11, 12, 13 and 14 represent modifications of
the said hinge.
The same letters of reference indicate corresponding parts in figures 1 to 9 both
inclusive.
a is a centrally disposed stay or middle part, and bare bearers at its outer end,
which when the hinge is in use, remain quiescent, and form the backbone as it were,
to the flaps c, which have inwardly directed joint straps c², and turn about the shanks
of the cupped plugs d, as joint centres, e are knuckle barrels, wherein coiled springs f
are enclosed, and with their ends f2, which are directed crosswise, taking into forked
inner ends d², of the capped plugs d, as aforesaid:
The binge has an adjustment and fixed side, the former is marked D, and the
latter D¹. The shanks of the capped plugs on the adjustment side, have a series of
all-through holes d³, made through them, wherein pegs d' take, for keeping the springs
at tort, or in position after adjustment, while the heads d³ of these said plugs, have
capstan, holes d made through them, for the winding up, or tensioning of the
springs.
The shanks have also annular channels do, made within them, wherein the ends do,
of screw pins or pegs take themselves, and prevent the said plugs from being
withdrawn.
The non adjustment side of the hinge has only a cross pin d³, passing through the
joint plugs, d, which form the centres around which, the flaps and knuckles of
the hinge turn.
Directed and fitting within the tops of the knuckle barrels e, are shouldered caps e?,
between which, and the inside faces of the bearers, the flap straps c³ work.
In the single action linge figure 10, the means of adjustment are the same as
that of the double action hinge as herein before described.
In figure 11, the base of the head is made toothed or pinion like, and with the
affixing pin taking within one of the gaps of the said head, and with its inner end
falling into a hole in the carrier. Figure 12 is a plan of figure 11, with parts in
section.
c, c are hinged flaps, with straps c², and knuckles e, formed as before from out of
open-ended tubing, with shouldered ends e. The base do of the head of the plug,
is serrated or toothed, and within one or other, of the holes in the carrier' b, the
peg d takes.
Figure 13 represents another form of my invention, in which the plug, whose inner
end takes upon the spring, is kept in its adjusted position by a sliding pin, working
within the top of a carrier.
c, c are the flaps, d³ is the head of the plug, do the base, pierced with capstan like
holes, wherein a peg d', taking within a forked snug 63, on the carrier 6 takes. c³ are
the straps of the flaps, and e is the barrel.
By rotating the head d³, and sliding the peg d' into one or other of the holes in
the base of the said head, the spring contained within the barrel, is affixed in its
adjusted position. The direction of motion of the peg may be oblique instead of
straight as represented.

page_text: Figure 14 is a plan of figure 13, showing the forked snug on the top of the carrier,
and between or through which, the peg for the affixing of the plug, comes.
•
Figure 15 represents my invention applied to a helical door spring.
a is an attachment plate, with carriers b; c is a flap or short arm, with straps or
loops 2, wherethrough the shanks of plugs d, take, while e is a barrel, wherein a coiled
or other spring is enclosed.
The adjustment and affixing of the spring at tort, is effected exactly in the same
manner as has already been described in respect to a spring hinge.
Figure 16 represents my invention applied to a helical rod door spring.
a is the attachment plate, c is an arm, with straps e², and with the outer end of the
arm fitted with a rod, c, whilst between the inner faces of the arms, and the barrel
or knuckle, e, are carriers 6; and further, the adjustment of the spring enclosed within
the barrel, is made by the head, d³, like unto that of the preceding arrangements.
Figuré 17 represents a vertical section of a floor spring, provided with adjusting
means constructed and arranged according to my invention.
Figure 18 is a plan of the same, and figure 19 a cross section.
a is the spring enclosing casing, and 6 are coiled springs, enclosed between fixed
and movable abutment plates marked c, d; the former is fixed, while the latter is
movable, and is carried forward by the adjusting nut or head e, on the screwed end f
of an adjustment rod f, whose inner end f³ is jointed to an arm of a bell crank lever g,
jointed at 93, and with a wiper-arm g³, upon the underside of which, a roller h², carried
by a revolving axis h, takes and bears.
The spindle or axis which turns vertically, has a shoe 3, at the inner or socketed
end of an attachment strap i.
On the springs b requiring to be adjusted, the nut or head e is rotated, and the
distance between the fixed and movable abutment plates, changed as may be
required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
