PROVISIONAL SPECIFICATION.
Improvements in and connected with Means for Securing Together
Hand Rails or other Parts Requiring Coupling.
I, EDWARD JAMES COUPE, of 3, Haworth Street, Waterloo Road, Manchester,
in the County of Lancaster, Foreman-joiner, do hereby declare the nature of this
invention to be as follows:-
Heretofore hand rails have generally been secured together by means of joint
bolts or spindles furnished with a screw thread at each end and arranged
longitudinally in holes in about the middle of the respective rail ends formed in
connection with other holes at a right angle thereto and adapted to receive and
hide the nuts placed onto the said joint bolt or spindle and by means of which the
two rail ends were drawn together. Owing to the said nuts being at a considerable
depth in the said rails the turning of the nuts was rendered very difficult and
troublesome, which defect my invention has for its object to overcome.
To this end my invention consists in forming the said nuts externally with teeth
arranged in gear with another suitable wheel, worm or wheels in such a manner
that the said nuts can be turned from the outside of the rail continuously.
According to one form of my invention I make the said nut into a bevel wheel
and cause the same to be turned by a bevel pinion formed on a spindle mounted in
a round plug which is placed removably into the said nut hole and carries, at its
lower end by means of two flat springs, the aforesaid nut and a washer to be placed
onto the joint bolt or spindle in the rail. The upper end of the said plug is
formed with a screw thread upon which is placed an arm and a lock nut which
serve to adjust the length of the said plug in the nut hole according to the depth
of the latter so as to bring the nut just opposite the joint bolt or spindle end.
The outer end of the pinion spindle may be formed with a slit or square to allow
of it being turned by a brace or key or it may be furnished with a small handle.
The said uut wheel is arranged to turn upon the washer aforesaid which is placed
between the said nut and the nut hole, the side of the washer next to the nut hole
being in shape to conform therewith.
According to another form of my invention I employ a small bracket in the said
nut hole which remains permanently therein and in which is mounted the nnt which
forms the bevel wheel aforesaid and a bevel wheel in gear therewith having a short
spindle also formed with a slit, square or handle for the purpose aforesaid.
The invention is also applicable for joining the sides of tables or chairs or other
parts were the joint bolt is employed internally.

COMPLETE SPECIFICATION.
Improvements in and connected with Means for Securing Together
Hand Rails or other Parts Requiring Coupling.
I, EDWARD JAMES COUPE, of 3, Haworth Street, Waterloo Road, Manchester,
in the County of Lancaster, Foreman-joiner, 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 :-
Heretofore hand rails have generally been secured together by means of joint

page_text: bolts or spindles furnished with a screw thread at each end and arranged longitudinally
in holes in about the middle of the respective rail ends formed in connection with
other holes at a right angle thereto and adapted to receive and hide the nuts placed
onto the said joint bolt or spindle and by means of which the two rail ends were
drawn together. Owing to the said nuts being at a considerable depth in the
said rails the turning of the nuts was rendered very difficult and troublesome, which
defect
my
invention has for its object to overcome.
To this end my invention consists in forming the said nuts externally with
teeth arranged in gear with another suitable wheel, worm or wheels in such a
manner that the said nuts can be turned from the outside of the rail continuously.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section and Fig. 2 a plan of a hand rail joint coupled in
accordance with my invention.
Fig. 3 is an elevation of the coupling apparatus detached and
Fig. 4 partly a side view and partly a longitudinal section of a modification of
my invention.
In carrying out my invention and referring to Figs. 1, 2 & 3, according to one
form I construct the nut so as to serve as a bevel wheel a and cause the same to be
turned by a bevel pinion b formed on or fixed to a spindle c mounted in a frame or
plug e which is placed removably into the nut hole of the hand rail g, g¹, and
carries, at its lower end by means of two flat springs h, the nut a and a washer i to
be placed onto the joint bolt or spindle k in the rails g, g'. The upper end of the
frame or plug e is formed with a screw thread d upon which is placed an arm
having a projection and a lock nut m the said arm and nut serve to adjust the
frame or plug e in the nut hole f according to the depth of the latter so as to
bring the nut a and washer i just opposite the joint bolt or spindle end k and the
arm also to prevent the apparatus from rotating in the nut hole ƒ by the
projection abuting against the side of the rail g.
If desirable the arm 1, l', may be dispensed with and a grooved cam m at the
inner end of a spindle o mounted in the frame or plug e employed, see dotted
lines Figs. 1 & 2, which cam by means of the handle p can be turned so as to
project passed the periphery of the frame or plug e and to grip the side of the
nut hole. When the arm 1, 1 is dispensed with the nut m takes its place.
The outer end of the pinion spindle c may be formed with a slit or square (as
shown in the drawing) to allow of it being turned by a brace or key or it may
be furnished with a small handle. The nut wheel a is arranged to turn upon the
washer i aforesaid, which is placed between the nut a and the nut hole f, see
Figs. 1 & 2, the side of the washer i next to the nut hole f being in shape to
conform therewith. A similar nut but without teeth is employed in a hole f¹ in
the other rail end g¹.
According to another form of my invention, see Fig. 4, I employ a small frame
or bracket e in the nut hole which remains permanently therein and in which is
mounted the nut a which forms the bevel wheel aforesaid and a bevel pinion b in
gear therewith having a short spindle c also formed with a slit, square or handle
for the purpose aforesaid.
The invention is also applicable for joining the sides of tables or chairs or other
parts where the joint bolt is employed internally as will be readily understood.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
1st. The method of securing together hand rails or other parts requiring coupling
consisting in forming the bolt or spindle nuts with teeth and turning the same by
suitable gearing employed in the nut hole, substantially as and for the purpose set
forth.

page_text: 2nd. An apparatus for placing the nut, specified in the preceding claim, in
position and turning the same onto the said bolt or spindle, consisting of a frame or
plug e adapted to be placed into the nut hole f, the inner end of which frame or
plug is formed with spring grippers / adapted to hold and place in position in the
nut hole the toothed nut a and a washer i, the said frame or plug carrying a
spindle c furnished at its inner end with a wheel b in gear with and adapted to turn
the toothed nut a, substantially as and for the purpose specified.
3rd. In combination with the apparatus, specified in the preceding claim, means
for adjusting and securing the plug in the nut hole, substantially as and for the
purpose specified.
4th. The modification shown in Fig. 4 of annexed drawing, substantially as
described.
