page_text: We THOMAS GOLDSWORTHY CRUMP Junior, Engineer and Surveyor, Borough
Engineers office and SAMUEL EDMUND WALDEGRAVE, Mechanical Engineer of
Braeholm, both of Taunton in the County of Somerset do hereby declare the
nature of this invention to be as follows:-
The object of our invention is the production of a front, rear or double steering
type of tricycle which may be converted into a single or tandem machine as
required with the greatest facility without impairing the strength or working
capabilities of the machine. A.front steering machine when reversed is applicable
as a rear or double steerer.
According to our invention we provide an attachment for the rear connection
with the bearings or frame of the axle of the driving wheels which can be fitted
thereto or removed therefrom at pleasure; for this purpose there is a forked
bracket on the main axle supporting a standard which latter carries the arm
carrying the front saddle and the same standard at top is supplied with a luggage
carrying frame. The rear attachment before referred to is connected to and sup-
ported by the said standard and axle fork, to the standard by a hinge joint collar
and to the fork by a socket joint. This hinge is composed of a socket fitting on
top round the standard and embracing same, the socket is hinged on one side and
is provided on the opposite side with flanges and bolt holes through which a bolt is
passed secured at top or bottom by a nut or pin; by removing the nut or pin and
bolt the socket can be opened about the hinge, and removed from the standard;
and by replacing the bolt and nut or pin the socket is securely held in position on
the standard. The fork carries a second arm which latter is carried in slots or
lugs on the fork and is held in position by the said slots or lugs with or without a
set screw pin or otherwise. The rear standard for the back saddle is carried by
this bracket which standard also passes through a fixed union joint in connection
with the socket hinge on the front standard. The rear driving gear is central and
is from the tail end of the rear standard to the main axle and thence to the fore
carriage which may be either side or central as desired.
To convert from double to single machine, unfasten spring link or bolt in rear
chain and brake band, take out the bolt in socket or hinge joint on front standard
open the hinge of same when the hind attachment can be lifted out of the slots or
lugs or slid back thereby removing the hind frame with handle, saddle and other
parts leaving a perfect single machine.
These attachments are applicable to other velocipedes than those described.

We, THOMAS GOLDSWORTHY CRUMP Junior, Engineer and Surveyor, Borough
Engineers office, and SAMUEL EDMUND WALDEGRAVE, Mechanical Engineer, of
Braeholm, both of Taunton in the County of Somerset 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:-
°
The object of our invention is the production of a front, rear, or double, steering
type of tricycle which may be converted into a single or tandem machine as
required, with the greatest facility, without impairing the strength or working
capabilities of the machine. A front steering machine when reversed is applicable
as a rear, or double, steerer.
According to our invention we provide means of attachment for the rear, or
detachable portion of the framework to the bearing bracket on the axle of the
driving wheels, which rear portion of the framework can be fitted thereto or
removed therefrom, at pleasure, all as hereafter described.
And in order that our invention may be fully understood, and readily carried
into effect we will describe the same with reference to the accompanying drawings.
Like letters of reference refer to corresponding parts in all the figures.
Figure 1 is a sectional side elevation of a front steering tandem tricycle, con-
structed so as to be convertible into a single machine-according to this invention.
Figure 2 is a sectional elevation, and Figure 3 a plan shewing on a larger scale one
arm of a forked bracket which supports the framework of the machine, and also
shewing method of coupling the adjustable or rear part to the front or main portion
of machine, as hereafter described. Figures 4 and 5 shew in sectional elevation
and plan respectively, a similar method of coupling to that shewn at Figures 2
and 3 but of varying form. Figures 6 and 7 are opposite side elevations, Figure 8
is a sectional plan, and Figure 9 is a perspective view, shewing hinge clip, as
hereafter described.
Figures 10 and 11 shew a sectional elevation and a horizontal section of a key
for securely locking such hinge clip.
A is the forked bracket on the main axle B supporting a standard C, which
latter carries the arm D, supporting the front saddle D¹, and the same standard C
carries at top a luggage carrying frame E. The rear or detachable portion of
the framework F before referred to is connected to and supported by the said
.standard C by a hinge joint collar, and is also coupled to the forked bracket A on
the main axle by, a socket coupling. This hinge shewn detached at Figures 6, 7, 8
and 9 is composed of a socket F' fitting and embracing the standard C.
The socket F¹ is hinged at F1x on one side, and is provided on the opposite side
with flanges and bolt holes, through which a bolt F is passed, secured at top or
bottom by a nut or pin; by removing the nut or pin and bolt F2 the socket F¹ can
be opened about the hinge and removed from the standard, and by replacing the
bolt and nut or pin the socket F¹ is securely held in position on the standard.
Or, instead of the bolt and nut E² we may use such a spring key as that shewn
at Figures 10 and 11, consisting of a split pin F2 having a tube Fx outside it, and

page_text: secured thereto by brazing, and having a through pin or rivet at the upper end.
The lower ends of said pin F have projecting spring catch like ends for effectually
preventing the pin F2 from being withdrawn until such ends are compressed to the
same diameter as the tube. And in order to prevent any rattle, and to ensure the
firm clasp of the hinge socket F¹ the interior is provided with a leather lining F³
best seen at Figure 8..
The hinged socket joint F¹ is fixed to the vertical stem of the rear portion of
machine F by a suitable bracket arm such as that marked G and when in position
the socket F clasps the vertical standard C near the upper end of same as before
mentioned and shewn at Figure 1 of the drawings.
The rear detachable framework F is further held in position and coupled to the
front part of machine, and for this object there is provided, fixed to the vertical
standard F, a forked bracket H shewn detached at Figures 2 and 3, or 4 and 5.
The forked bracket H divides into two arms, each of which is bifurcated at its end;
the bifurcated end of one of such arms H only being. shewn at Figures 2 to 5.
Each of the. forked arms of the bracket A supporting the front standard C, is
provided on each side with lugs or projecting pieces A¹ A¹. One only of the arms
of the bracket A is shewn in Figures 2 to 5. When in position the bifurcated
ends of the arm H embrace each of the arms of the bracket A and pass between
the lugs A¹ A¹ and the said bracket arms H are thus firmly held in position by
the slots or lugs A¹ A¹. It may if desired, be still further secured in position by a
set screw, pin, or otherwise as at H¹ Figure 2.
At Figures 2 and 3 the ends of the bracket arms H pass through and between
the lugs AA, and are formed with shoulder pieces which abut against said
lugs A A¹ while at Figures 4 and 5, the ends of arms H H are curved, and pass
between curved lugs A¹ A¹ allowing of their connection with ease and smoothness
of motion.
The rear driving gear J is central and is from the tail end of the rear standard F
to the main axle, and thence to the fore carriage which may be either side, or
central, as desired.
To convert from double to single machine, loosen the rear chain by expanding
the spring link, if so fitted, or bolt, and also the brake band, take out the bolt
from socket or hinge joint on front standard, open the hinge of same when the
hind portion of framework F can be lifted out of the slots or lugs, or slid back, as
at Figures 4 and 5, thereby removing the hind frame with handles, saddle, and
other parts leaving a perfect single machine.
These attachments are suitable for other velocipedes than those described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
In convertible tandem or single velocipedes the means described, consisting of
hinge joint collar F and socket coupling H. and parts connected therewith, for
adjustably connecting and disconnecting the portion of framework for carrying
a second rider, substantially as hereinbefore described with reference to the
accompanying drawings.
