PROVISIONAL SPECIFICATION.
Improved Devices for Connecting Various Bodles, Frames of
Machinery, Hubs of Wheels, and other Structures.
I, RICHARD TIMSON of No. 83 Overton Road West Humberstone Leicester in
the County of Leicester Newsagent do hereby declare the nature of this invention
to be as follows:-
This invention relates to improved devices for connecting various bodies, frames
of machinery, hubs of wheels; and other structures such as principal supports for
bridges, buildings, or cross bars where it is intended to pull two other parts inwards
parallel; or to secure projections either from an angular, vertical or horizontal
base; holders for various goods, securing hangers, supports for shelves and the
like, or to make a close joint wherein the male part or tongue will fit closely to
the female part or socket, bringing the two surfaces or faces close together.
any
My invention consists of a straight, curved, angular or semi-circular wedge
shaped tongue having dove-tailed sides, secured or forming part of suitable
end, or plate, or corner plate having one side at right angles to the other, or two
sides as the case may be; and forming male, or tongue, and female or socket
plates, or ends in metal bars, or beams or other supports. When the tongue is
placed in a grooved out portion of the widest part of the corresponding wedge
shaped recess or socket, with dove-tailed sides it cannot be displaced, a locking
bolt or screw being used to keep the parts secure. Such devices, if in the form of
plates are cast to the size and shape desired, so that they can be let in flush if to
be placed upon wood. If the articles are of metal they can be cast or otherwise
made in the ends or face thereof. One of the plates is provided with a wedge
shaped tongue or projection, the sides (as before stated) being dovetailed, the
upper or wide part of the tongue being rounded off to a point level with the plate,
by this means it can be more easily removed from the upper grooved out portion
of the corresponding recess or socket in the opposing plate, both may have angles
or sides to suit the article they have to be secured to.
In both the male or tongue,
and female or socket plates projections are left in rear of the "tongue" and
recess "in casting so that they can be embedded in wood or the like. It will be
understood that in metal ties, frames or the like, the said connecting devices are
cast in one with the article. Or if desired such devices may be hinged, or double
having a tongue on each side of a centre upright fitting in respective angular
66
sockets.
In another form two semi-circular tongues are used describing a circle, sufficient
space being left between them so as to allow the lower end of the wedge shaped
tongues to be placed in the corresponding grooves in the socket plate, such a
pattern being applicable for securing flat surfaces together, or movable beds or
tops to tables, machines, or any other article or structure. To secure the two
surfaces together the socket plate is turned a half turn, by a swivel joint if
necessary; which will bring the tongues into place. This means of connecting
two surfaces together can be either in a vertical, horizontal, angular or any other
position. When the connecting surfaces or ends are of a circular form the tongues
and sockets would be convexed accordingly. Or a series of any of the above may

device, or for corners, or mitres of frames and the like.

Improved Devices for Connecting Various Bodies, Frames of
Machinery, Hubs of Wheels, and other Structures.
I, RICHARD TIMSON of No. 83 Overton Road West Humberstone Leicester in
the County of Leicester Newsagent, 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 to improved devices for connecting various bodies, frames
of machinery, hubs of wheels; and other structures such as principal supports for
bridges, buildings, or cross bars where it is intended to pull two other parts inwards
parallel; or to secure projections either from an angular, vertical or horizontal
base; holders for various goods, securing hangers, supports for shelves and the
like, or to make a close joint wherein the male part or tongue, will fit closely to
the female part or socket, and bring the two surfaces or faces close together, as
seen in Figures 3, 5 and 9 of the drawings accompanying this Specification, in
which―
Figure 1 represent the tongue and socket joints constructed in accordance with
my invention.
Figure 2 is an inside view of a socket having flange thereto.
Figure 3 shows the tongue and socket joint locked together.
Figure 4 is a side and upper view of a double tongue employed to make a
detachable tongue in connecting two surfaces together as seen in Figure 5.
Figure 6 shows a stamped out tongue and socket in a skeleton form for metal-
work.
Figure 6 is a sectional view of same through line X.
Figure 7 illustrates in perspective a socket of a circular form.
Figure 8 the tongue or tongues of same.
Figure 9 shows in dotted line the circular tongue and socket joint locked together,
the arrows denoting the way the base is turned in connecting the said joint.
Figures 10 and 11 are side views of a concave tongue and socket, and Figure 12
a front, or end view of a convex tongue to fit in a correspondingly shaped
socket.
The letters of reference refer to like parts in all the figures.
My invention consists of a straight, curved, angular, or semi-circular wedge
shaped tongue A having dove-tailed sides a secured or forming part of any suitable
end, or plate B, or corner plate having one side at right angles to the other
see Figures 1, 2 and 3" or two sides C "dotted line" Figure 3; as the case
may be, and thus forming the male (tongue) or female (socket) plates or ends in
metal bars, wood beams, or other supports.
When the narrow end a of the tongue A is placed in the grooved or curved out
portion D of the widest part of the corresponding wedge shaped recess or socket E,
with dove-tailed sides and passed down it cannot possibly be displaced except by
raising it up again, and to secure the plates together a locking bolt F, Figure 1
("left hand side portion") or screw may be employed. Such devices if in the
form of plates Figures 1, 2, and 3, or single by cutting, them, or casting with only
one side as at dotted line X, are cast to the size and shape desired from the
smallest size to one large enough to carry a beam of a building, and they are

page_text: capable of being let in flush upon wood. If the articles are desired to be wholly
of metal they can be cast or otherwise made in the ends or face thereof.
The wedge A as will be seen by reference to Figures 1 or 8 is tapered at its
widest part to secure it being more readily removed from the tapered grooved out
portion D of the recess in the socket E in the opposing plate B₁, both plates may
have sides or angles thereto as shown in the drawings to suit the corner or other
surface of the article they have to be secured to. In both plates projections G
are left in casting to give strength and uniformity in the thickness, such portion
being embedded in the wood, or other material forming the body of the structure.
It will be well understood that I can when adapting my invention to metal work,
such as ties for buildings, frames and the like cast or otherwise make the wedge
and socket with the article, and such plates may if necessary be hinged, or have
two sides or angles as indicated by dotted line B* Figure 3 a wedge such as A¹
Figures 4 and 5 would appear on each side of the "centre vertical dotted line b
Figure 4" fitting in their sockets E¹ Figure 5. In another form 1 employ two.
semi-circular wedges A* "see Figures 7, 8 and 9" and allow a space between them
so as to allow the end of the wedge to be placed in, and move freely up the
grooves E in the socket plate E2 this particular form is applicable in securing
movable beds, tops of tables or other flat services together, an example is shown
in Fig. 9 a half turn of the socket plate E' is necessary, in the direction of the
arrows to lock them in position, either in a vertical, horizontal, angular or in any
other plane. If such surface or plane be convexed the tongues and sockets will be
convexed accordingly "see examples A³, and A' Figures 10, 11 and 12."
Or a series of any of the above may be fitted on one plate or angular base,
corners, mitres of frames and other such bodies.
In Figures 6 and 6ª is shown a wedge tongue A and socket E' stamped out of
any suitable metal and applicable for the ends of rods, or ribs of various kinds, or
at the ends of hollow articles or solid posts and the like.
Such wedges and socket joints are useful for many other purposes than those
recorded or herein illustrated without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Improvements in devices for connecting together various bodies, frames, structures
and the like consisting of wedged tongue and socket plates forming two or more
sections, or joints, the tongue or tongues being narrow at one end, and tapered or
curved at their wider end to fit a corresponding shaped groove, or grooves in the
socket plate for the purpose substantially as herein described and illustrated in
the several figures of the accompanying drawings.
