PROVISIONAL SPECIFICATION.
Improvements in Looking Wheels for the Fore-oarriages of
Vehicles.
I, CALEB RICHARD TURNER, of 372, Stuyvesant Avenue, Brooklyn, in tho
County of Kings, and State of Now York, United States of America, Mann-
facturer, do hereby declare the nature of this invention to be as follows:-
IL
My invention relates to the locking wheels or turning gear for the fore carriages
of four-wheeled vehicles, and particularly those in which roller bearings are used to
enable the vehicle to turn very easily. The object of my invention is to provide
locking wheel which has a strong but light roller bearing housed in such a way
that it cannot become clogged with dirt and dust and is also shielded from water,
which has the housing of the roller bearing formed of angle-irons shaped also to
serve as bearing plates, and in general to produce a fifth wheel which combines
simplicity, cheapness, and efficiency, to the greatest possible extent.
The bottom bearing plate is of angle-iron having a flat surface to serve as the
bottom roller path and an inner annular flange which serves as a guide for the roller
bearing and also forms one side of the housing for the bearing. The roller path
is supported on a bed frame connected with the fore axle. The rollers are arranged
in a circle and have end trunnions journalled in a pair of concentric rings, the
outer ring being formed with corrugations running in the circumferential direction,
which stiffen the ring and enable it to be made out of light material. The inner
ring may be made in the same way, if desired. The rings aro narrower than the
height of the rollers, so that the rollers project at top and bottom from between
the rims. The top bearing plate or roller path attached to the underside of the
vehicle body, rides on the rollers and forms the second half of the housing, this
plate being also angular in cross-section and of circular shape, its flange forming
the onter side of the housing in which the rollers are contained.
In certain kinds of vehicles it is necessary to have the top of the locking
wheel convex and heretofore no angle iron has been made with one side convex,
and I claim this as a novel feature of the invention.
The top bearing plate or roller path is preferably made to project inward slightly
beyond the flange of the lower hearing plate so as to better serve its purpose as
a housing top, and a little space is left between the said flange and the top bearing
plate and between the bottom plate of the flange of the top bearing plate so that
any water or dust which may blow into the housing may pass through the same
without clogging the rollers. The rollers are held in such a way as to be
accurately guided and so that they cannot be accidentally displaced and by reason
of the manner in which the rollers are held between the top and bottom plates
the vehicle inay be turned with the utmost facility, whilst the oppositely-arranged
angular bearing plates form a housing with the least possible amount of metal.

Vehicles.
I, CALEB RICHARD TURNER, of 372, Stuyvesant Avenue, Brooklyn in the
County of Kings, and State of New York, United States of America, Mann-
facturer, 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 relates to improvements in the locking wheels or turning gear for
the fore-carriages of four-wheeled vehicles and particularly those in which roller
bearings are used to enable the vehicle to turn very easily.
The object of my invention is to provide a locking wheel which has a strong but
light roller bearing housed in such a way that it caunot become clogged with dirt
and dust and is also shielded from water, which has the housing of the roller
bearing formed of angle irons shaped also to serve as bearing plates, and in general
to produce a locking wheel which combines simplicity, cheapness, and efficiency, to
the greatest possible extent.
To these ends my invention consists of certain features of construction and
combinations of parts, which will be hereinafter described and claimed.
Referenco is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a cross section of the locking wheel embodying my invention, shewing
the same applied to a wagon.
Figure 2 is a plan view of the bearing rollers and their supporting rims, and
Figure 3 is an enlarged cross section on the line 3-3 of Figure 1.
Similar figures of refereuco indicate corresponding parts in all the views.
The looking wheel has a bottom bearing plate which is of angle iron having a
Ant surface 10 to serve as the bottom roller path and an inner annular flange 11
which serves as a guide for the roller bearing and also forms one side of the
housing for the bearing. The roller path 10 is supported on a bed frame 12
connected with the fore axle 13 of the vehicle. The rollers 14 are arranged in a
circle and have end trannious 14 (Figure 3) which are journaled in a pair of
concentric rings 16 and 16, the outer ring 16 being formed with corrugations 17
running in the circumferential direction, which stiffou the ring and enable it to be
made out of light material; the inner ring 15 may be made in the same way if
desired. The rings 15 and 16 are narrower than the height of the rollers 14 80
that the rollers project at top and bottom from between said rings. The top
bearing plate 19 of the locking wheel or roller path attached to the underside of
the vehicle body rides on the rollers and formis the second half of the housing, this
plate being also angular in cross section and of circular shape, its flange 18 forming
the outer side of the housing in which the rollers are contained.
In certain kinds of vehicles it is necessary to have the top of the locking wheel
convex, and heretofore no angle iron has been made with one side convex, as
shewn in Figure 1, and I claim this as a novel feature of the invention.
The top bearing plate or roller path 19 is preferably made to project inward
slightly beyond the flange 11 of the lower bearing plate so as to better sorve its
purpose as a housing top and a little space is left between the said flange 11 and
the top bearing plate and between the bottom plate 10 of the flange 18 of the top
bearing plate so that any water or dust which may blow into the housing may pass
through the same without clogging the rollers 14. The rollers 14 are held in such
a way as to be accurately guided and so that they cannot be accidentally displaced
and by reason of the manner in which the rollers are held between the top and
bottom plates the vehicle may be turned with the utmost fucility, whilst the

page_text: oppositely arranged angular bearing plates form a housing with the least possible
amount of metal.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A locking wheel for the fore-carriages of four wheeled vehicles, comprising
oppositely arranged circular angle irons forming respectively the upper and lower
bearing plates of the locking wheel, and a series of rollers arranged between the
angle irons, substantially as described.
2. A locking wheel for the fore-carriages of four-wheeled vehicles, comprising
oppositely arranged circular angle irons forming respectively the top and bottom
bearing plates of the locking wheel and with their side flauges concentrically
arranged, and a series of bearing rollers arranged between the angle irons and
journaled in concentric rings, substantially as described.
3. A locking wheel constructed substantially as shewn in the accompanying
drawings and described in the foregoing Specification.
