IMPROVEMENTS IN SECURING WHEELS OR PULLEYS TO AXLES OR SHAFTS
Year: 1884

page_text: We WILLIAM Cook the Elder, and THOMAS Cooк, both of the Glasgow Steel
Works, Washford Road, Attercliffe, in the County of York, Steel Manufacturers
do hereby declare the nature of our said invention for IMPROVEMENTS IN SECURING
WHEELS OR PULLEYS TO AXLES OR SHAFTS to be as follows:-
Our invention relates to improvements in securing wheels or pulleys to their
Axles or Shafts.
·
In carrying our invention into practice, we enlarge one of the arms of the wheel
or pulley at its junction with the boss of the wheel (or between the arms if
preferred) and form a keyway through it, preferably in a line with the axle or
shaft.
Near the centre of the keyway we form a second opening, vertically through the
metal of boss, into the centre hole.
A Stud block; that is a block having one or more round or elongated studs
formed upon and projecting from its lower surface, and preferably made of steel, is
fitted loosely into the vertical opening, and may be forced and held down by a key,
driven into the horizontal keyway.
The Stud or Studs enter into corresponding holes (made in the axle or shaft)
when the parts are brought to their proper relative positions, thus firmly securing
the wheel or pulley upon its axle or shaft.
The use of studs formed upon a studblock as before described is very simple and
effective, and is a less expensive method than the use of parallel keys that require
a skilled workman to fit and secure them in their place and is also superior to the
ordinary set screw.

We WILLIAM Cook, the elder, and THOMAS Cook, both of the Glasgow Steel
Works, Washford Road, Attercliffe, in the County of York, Steel Manufacturers
do hereby declare the nature of our invention for IMPROVEMENTS IN SECURING
WHEELS OR PULLEYS TO AXLES OR SHAFTS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
Our invention relates to improvements in securing or fastening wheels and
pulleys upon their axles or shafts.
We anuex a sheet of illustrative drawings in which Fig. 1 represents a pit
corve-wheel fitted with our improved method of fastening.
Fig. 2, is an enlarged sectional view of the hub of a wheel or pulley, with the
various parts constituting the fastening.
Fig. 3, is a cross section of same.
Fig. 4, is the key-Fig. 5, is the Wedge..
In carrying our invention into practice, we enlarge one of the arms of the wheel
or pulley at its junction with the hub of the wheel, as shown in Fig. 1 at A, (or
between the arms if preferred) having a passage or key way B through it in a line
* with the axle or shaft C..
In the centre of the passage B, we form a second opening or keyway D vertically
through the metal of the hub E, and opening into the centre hole.
A key or stud block F, with one or more studs G of any desired shape but
preferably round as shown in Fig. 4 and projecting from its lower surface, is fitted
losely into the opening D.
The stud G (or studs) enters into a corresponding hole (or holes if more than
one stud is used) made in the axle or shaft, and by driving the taper wedge or
key H, through. the opening B, it acts upon the top of the stud block F, and
firmly secures all the parts together in their relative positions.
The use of a stud block with, one or more projecting studs is very simple and
effective, and cheaper than the use of ordinary keys which require a skilled.
workman to fit into their place, and is more reliable than a set screw.
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 —
*
1 In securing wheels or Pulleys to their axles or shafts, the use of a stud
block F having one or more studs G, of any desired shape, to fit into corresponding
holes formed in the shaft or axle, for the purpose specified, and substantially as
described and illustrated.
2 In securing wheels or pulleys to their axles or shafts, the arrangement of the
recesses or keyways B and D, in combination with the wedge or key H, and the
stud block F, having one or more studs G, as herein before described and illustrated.
Dated the 29th day of November 1884.
