do hereby declare the nature of this invention to be as follows.
Engineer,
The object of my invention is to design a joint or connection for tubulai, flat or
other shaped pieces, so that they can be quickly screwed together, whilst keeping
a certain relative position and each piece coming up to a stop In canying my
ideas into practice I screw a piece of bar or tubing half with a right and half with
a left hand screw thread, sometimes leaving a blank space between the two threads
The said right and left hand threads may be of same or a varving diameter, and
the blank space, if any, may sometimes be of greater diameter than either of the
right and oi left handed screwed parts My invention consists in fitting centially
on the screwed bar or tube a movable piece of vaiving width and connected thereto
by pin, key, flats or other means having for object that the said screwed bai oi tube
may be turned, consequently when two separate pieces so sciewed air brought
together the turning of the screwed bar or tube inserted therein will draw them
up, so that they will meet on the movable part, no matter at what position of
the screwed part they may have started. The said movable part may be shaped
as a nut and or have flanges to overlap the ends of tubes to be jointed.

HENRY STANDRIDGE, 120, Addison Gardens, West Kensington, formerly of 1.36,
Wellesley Road, Chiswick, London, W, 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
My invention consists in fitting on a screwed bar or tube a moveable piece of
varying width and shape, connected thereto by pin, kev, flats or other means, so
that the said bar o tube may be turned thereby
Thus two pieces will be caused to be joined and meet on the said moveable piece,
whilst keeping a certain relative position
To carry this out the said bar or tube may be screwed right and left hand,
or only screwed one end and have a flange at the other end to take the place of the
screw A blank space can he left on between the two threads, upon which the
moveable piece is mounted and free to slide
The blank space may be of the same or greater diameter than the screw threads
The said right and left hand sciew threads may be of the same or varying
diameter

of a bicycle frame
Fig. 2, is an end view of the joint above
Fig 3, shews a top view, partly in section of 2D shaped tubes joined together.
Fig 4, shews the form of moveable piece with flat to operate the sorewed
piece
Fig 5, is an end view of this form of the joint.
Fig 6, is a view, partly in section, of the joint as applied to jointing a boiler
tube to the plates of a furnace
Fig. 7, 18 a view, partly in section, of 2 boiler tubes joined together by means of
my joint.
In Figure 1,
A, is the moveable piece, by means of which the screwed internal tube or bar is
operated
13, 18 the screwed tube
C, is the front lug of a bicycle
D), is the internal sciewed tube or bar, which has right and left hand screw
threads & and a plain part less in width than the moveable piece A
E, E, in Figure 2 are the keys or projections on the said screwed tube D which 2
engage in slots in the moveable piece A.
In Figure 3 and 5,
F, F, are the 2, D shaped tubes
G is a screwed bar, with threads of varying diameter and having a plain
part g¹.
H, is the moveable piece with a flat h¹, shewn in Figure 4, (a corresponding flat
being made on the screwed bar G)
In Figure 6,
I, is the plate of the furnace
J, 18 the tube screwed at one end and having a flange 1, in heu of being screwed
at the other end
K, is the moveable piece, having a bevel part A, and also slots, as shewn in
Figure 2, fitting keys or feathers of the part J
L, is the water tube of the boiler
M, M, are copper, lead or other washers to make a tight joint
In Figure 7;
N, N, are two water tubes
0, is the moveable piece having bevel edges o³, and also slots, as shewn in
Figure 2, fitting keys or feathers of the part P
P, 18 the screwed tube, which 18 turned by means of the moveable piece o
Q, are washeia to make a tight joint
The dimensions and shape of the various parts may be altered to suit different
circumstances, and the moveable piece invented by me, may have to be made with
flanges, bevels both ways and various devices for enabling it to be rotated
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim 18:
1 A moveable piece, mounted as described on a bar or tube screwed or screwed
and flanged, that by means of the said moveable piece, the said bar on tube may be
turned and bring two pieces to meet on the said moveable piece, whilst retaining
their said relative position
