Improvements in or appertaining to Road Vehicles.
I, SAMUFL SMITH, of 14, Chapel Street, in the City of Bradford, Mantle Maker,
do hereby declare the nature of this invention to be as follows,-
This invention relates to improvements in or appertaining to road vehicles and
its object is to enable such vehicles to more advantageously utilise ordinary tram-
way fails where the lines are laid.
For this purpose I provide a couple of guide wheels on the front of the vehicle
the same guage as the tramway 1ails and having flanges on peripheries of a suitable
shape to engage the rails These guide wheels are capable of being raised on lowered
and provision is made to bring them down to engage the rails when it is desired
to travel on the tramway lines and to raise them up when it 18 desued to leave
such rails
The guide wheels may be mounted upon slides or upon aims or then equivalent
controlled by a lever or a screw, or cam or the like
I may only use one guide wheel to engage the rails on one side only

Improvements in or appertaining to Road Vehicles
I, SAMUEL SMITH, of 14, Chapel Street, in the City of Bradford, Mantle Maker,
do hereby declare the nature of this invention and in what manner the same 19
to be performed, to be particularly described and ascertained in and by the
following statement
-
This invention relates to improvements in or appertaining to 1oad vehicles and
its object is to enable such vehicles to more advantageously utilise ordinary tram-
way rails where the lines are laid
For this purpose I provide a couple of guide wheels on the front of the vehicle
the same gauge as the tiamwar iails and having flanges on peripheries of a suitable
shape to engage the rails These guide wheels are capable of being raised or lowered
and provision is made to bring them down to engage the rails when it 18 desued
to travel on the tramway lines and to raise them up when it is desired to leave
such rails
To fully describe my invention reference is made to the accompanying sheet
of diawings forming a part of thus specification in which similar letters of reference
indicate similar parts in both the figuies

page_text: Figure 1, represents a side elevation of such portions of a two wheeled cait as
are necessary to illustrate the application of my improvements thereto, the eart
shafts are shown broken away to economise space
Figure 2, is a front view of Figure 1
The shafts A, A the body B and the wheels C are of ordinary construction.
A guide sleeve D is fixed by arms D on its screw cap D³ to each of the shafts A
and A. Stiffening stays D and 15 fixed respectively to the rear end of the shafts
and the cross piece A³ extend down and are connected to the collars I fixed round
the guide aleeve D The bottom ends of the guides D are made square in cross
section and the square ends of the slides fit the square ends of the guides and
extend up to the shoulder E³, Figure 1, and from that point are reduced in size
and made of round section The upper ends E of the slides pass through holes
in the caps 1) and are coupled to the chains E working on the quadrants F fixed
on the ends of the 1ocking shaft F mounted in bearings in the shafts A and A³.
The ends Es of the chains are secured to the horns E' of the quadrants and when
the lever fixed to one of the quadrants is moved from the position shown in full
in Figure 1 to that represented by the bioken lines the slides are lowered sufficiently
to bing the guide rollers & mounted on studs F8 in then lower ends E
down and permit them to engage the grooves in the tiamway rails when it is
desned to keep the wheels C upon the rails
The sleeves D each contain a powerful sping H compressed between the
shoulder E' and the underside of the cap D' The function of these springs is to
keep the wheels G pressed into the grooves of the rail and the quadiants are moved
sufficiently by raising the lever F³ to completely slacken the chains E' and permit
of this
Stops or catches J are provided on both A. and the front of the body B to hold
the lever in either position and the lever is made sufficiently springy in a lateral
or outward direction that it can be readily pushed over them Any other suitable
form of catch may be employed
The improvements can be applied to waggons and other four wheeled road
vehicles with equal advantage
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
The combination with a road vehicle of tramway guide wheels with means for
putting them in and out of operation, substantially as herein shown and described
and illustrated in the accompanying drawings
