PROVISIONAL SPECIFICATION.
Improvements in Locking Frames for Wagons and like Vehicles.
I, CHRISTEN NIELSON, of Brooklyn, County of Kings and State of New York,
745, Third Avenue, Carriage Builder, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the construction of a locking frame for the front wheels
of a wagon or other vehicle in such a manner as to obtain great steadiness and
lessen friction.
For this purpose, the circular upper ring which is fixed to the body of the vehicle,
has interposed between it and the circular lower ring, which is fixed on the fore
axle, a set of rollers having studs at their ends pivotted in two rings, one on each
side of the rollers, which preferably are slightly coned. As there is no perch pin to
centre the rings the upper ring is made of inverted trough section, the lower edges
of its sides turning in recesses formed at the edges of the lower ring these recesses
presenting shoulders which prevent the sides of the upper ring from moving out of
concentric position.
In order to increase steadiness, the rollers, instead of being truly cylindrical or
conical, may be somewhat bellied, the surfaces of the rings on which they bear
being somewhat concave.
Dated this 31st day of August 1898.

Improvements in Locking Frames for Wagons and like Vehicles.
I, CHRISTEN NIELSON, of Brooklyn, County of Kings and State of New York,
745, Third Avenue, Carriage Builder, 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 the construction of a locking frame for the front wheels
of a wagon or other vehicle in such a manner as to obtain great steadiness and
lessen friction.
For this purpose I make a locking frame as I shall describe referring to the
accompanying drawing.
Figure 1 is an elevation and Figure 2 is a section of a locking frame according to
this invention, Figure 3 is a plan, part of the upper ring being broken off to
shew the rollers below.
a is the upper ring which is fixed to the body of the vehicle and b is the lower
[Price 8d.]

page_text: ring which is carried on the fore axle. Between these rings a number of rollers r
have studs at their ends pivotted in rings c, the rollers and rings being all contained
within the hollow of the upper ring a which has the form of an inverted trough.
As there is no perch pin connecting the rings a and b, the lower ring b has at
each side shoulders d engaged between the lower edges of the sides of the upper
ring a so as to keep the two rings centred relatively to each other.
The rollers are somewhat coned or they may be somewhat bellied, the surfaces
of a and b on which they bear being made to suit them.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is: -
A locking frame for a vehicle consisting of two rings having rollers between
them, the upper ring being of inverted trough form with the lower edges of
its sides bearing against shoulders of the lower ring, substantially as described.
Dated this 30th day of May 1899.
