PROVISIONAL SPECIFICATION.
Improvements in Anti-friction Collars.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this Invention (a communication to me from abroad
by Joseph J. Ladd of Callao, Peru, South America,) to be as follows:-
The object of this invention is to provide an anti-friction ring to be placed upon
axles and shafts between the collars or bosses of wheels and journal boxes, to diminish
the friction between the boss or collar and the journal box.
The Invention consists in a split ring enclosed by a collar which is divided for
convenience in applying the ring to a shaft or axle and a lubricating device formed
on, or attached to, the collar for maintaining a constant lubrication.
The split ring is made in balves whose ends mutually interlock with each other. In
the one part is formed a key seat which fits a key fitted to the shaft upon which the
ring is placed. The split ring is preferably made of steel and hardened. A collar
preferably made of Lowmoor iron is fitted to the ring and is provided with a removable
section of sufficient width to permit of placing the collar, upon the ring or removing
it therefrom. The collar is formed with a block on its edge in which are made oil
chambers which communicate with each other and with a passage leading to the
interior of the collar. The oil which is gradually supplied through the said passage
to the interior of the collar maintaining a perfect lubrication of the collar without
depending upon the oil supplied to the journal box.

COMPLETE SPECIFICATION.
Improvements in Anti-friction Collars.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of 53,
Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this invention (a communication to me from abroad
by Joseph J. Ladd of Callao, Peru, South America) 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 this invention is to provide an antifriction ring to be placed upon axles
and shafts between the collars or bosses of wheels and journal boxes, to diminish the
friction between the boss or collar and the journal box.
The Invention consists in a split ring enclosed by a collar which is divided for con-
venience in applying the ring to a shaft or axle and a lubricating device formed on,
or attached to, the collar for maintaining a constant lubrication, all as hereinafter more
fully described.
Reference is to be had to the accompanying drawings forming part of this speci-
fication in which figure 1 is a side elevation of the improved anti-friction collar.
Figure 2 is an edge view. Figure 3 is a partial plan view. Figure 4 is an edge view
shewing the application of the collar to an axle, and figure 5 is a side elevation of the
halves of the inner portion of the collar. Similar letters of reference indicate corre-
sponding parts in all the figures.
To the shaft or axle A is fitted a ring B formed of two parts a a². Upon the
extremities of the part a' are formed right-angled hooks b which project outwardly

page_text: and upon the extremities of the part a, are formed right angled hooks b¹ which project
inwardly, the hooks being formed so as to receive the hooks b. In the part a is
formed a key seat c which fits a key fitted to the shaft upon which the ring is placed.
The split ring B is preferably made of steel and bardened.
A collar C, preferably made of Lowmoor iron, is fitted to the ring Band is provided
with a removable section D of sufficient width to permit of placing the collar upon
the ring B or removing it therefrom. The section D is grooved and the edges of the
gap in which the section is received are provided with tongues which enter the
grooved edges of the section, and the collar and the removable section are bored to
receive a bolt E the collar being provided with bosses d forming bearings for the head
and nut of the bolt. The collar C is formed with a block F on its edge in which are
made chambers e, e, f, which are closed by screw-plugs ee³. Below the screw plugs
there are passages g which form communication between the chambers e e¹ and the
central chamber f. The central chamber f communicates, by a passage h, with the
interior of the collar C. The chambers e e¹f are filled with oil which is gradually
supplied through the passage h to the interior of the collar C, thereby maintaining
a perfect lubrication of the collar without depending upon the oil supplied to the
journal box.
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. In an anti-friction collar, the combination of the ring B, formed of the parts a a¹
provided with hooks 6 61, and the collar C furnished with the removable section D,
substantially as specified.
2. In an anti-friction collar, the combination of the ring B, formed of the parts a a¹
provided with hooks bb, the collar C, furnished with the removable section D, and
the block F, provided with the chambers e e¹, f, and the passages g h, substantially as
specified.
