We, SAMUEL DRUMMOND, of Lumb Lane Mill, Bradford, in the County of York,
Manufacturer, and THOMAS ABBOTT, of 45, Victor Terrace, Manningham, Brad-
ford aforesaid, Engine-tenter, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in that class of speed regulator, or
auxiliary governors, particularly applicable to Corliss and similar engines, in
which the length of the governor rod connecting the main governor with the valve
gear is altered to regulate the speed of the engine.
For this purpose we employ a rotary disc driven by a belt or in any other con-
venient way from the governor driving shaft or other suitable part. Adjacent to
the rotary disc we mount a stud plate carrying two friction discs geared together
and having their peripheries close to but just clear of the periphery of the said
rotary disc. The said stud plate is mounted on a stud concentric with one of said
friction discs or a wheel geared thereto and it is connected to a lever or its equiva-
lent operated by the governor in such a way that any variation in the speed of
the engine brings one or the other of said friction discs into contact with the peri-
phery of said rotary disc and such friction disc is thereby rotated. One of said
friction discs is connected by bevel wheels and a pulley and driving strap or
equivalent means to the wheel nut or the like provided to adjust the length of the
said governor rod. . When the engine is running at normal speed neither of the
said friction discs are in contact with the rotary disc but any appreciable variation
in the speed causes (through the medium of the governor) one or the other of said
friction discs to be brought into contact with the rotary disc and the wheel nut is
thereby turned or adjusted in the direction required to regulate the speed.

in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-

is thereby turned or adjusted in the direction required to regulate the speed.
To fully describe our invention, reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar letters of refer-
ence indicate corresponding parts in each of the figures.
Figure 1, represents a front view of our improved regulator and Figure 2, is
a side view of the same.
The bracket A is supported and fixed in any convenient way and the bearing
piece B is fixed to it by the bolt 132. For convenience of adjustment of the bearing
piece a screw B³ is provided in the bracket to bear against the bottom of the bearing
piece. The short shaft C is mounted in the bearing piece and carries at one end
the pulley D by which it is driven by means of a belt from the governor driving
shaft or other convenient part. On the other end of the shaft the plate E is
fixed and the leather or other suitable disc E2 is clamped thereto by the ring E
and screws E. The two friction dises F and G geared together by the wheels F³
and G2 are mounted on studs F³ and G3 fixed in the stud plate H mounted on the
stud H fixed in the bracket A. The disc F has a toothed wheel J fixed to it
which engages the wheel K on the stud H3 and the bevel wheel L is fixed to the
wheel K. The bevel wheel L engages the bevel wheel N fixed on the shaft O
mounted in a bearing formed in the bracket P fixed on the stud H2 and the pulley R
is secured to the other end of the shaft O. The bracket P is capable of being
turned on the stud H2 and fixed thereon in any convenient position to enable the
pulley R to be connected by a band or its equivalent to the wheel nut in the
governor rod. The stud H³ in the stud plate H is connected by the rod S with
the governor and it will be evident that movement of the rod in either direction
will bring one or the other of the friction discs into contact with the disc E² and
through the medium of the connecting mechanism drive the wheel nut on the
governor rod and thereby lengthen or shorten said rod as may be required.
To allow free play to the governor the latter is connected to the rod S by the
collar T loosely mounted upon said rod and confined longitudinally thereon by the
springs V, V on the rod and held in position by the fixed collars W, W.
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:-
An engine speed regulator consisting of a rotary disc E, friction discs F and G

page_text: mounted on a pivoted stud plate controlled by the governor, and mechanism con-
necting said friction discs with a wheel nut in the governor rod, all combined
and operating substantially as herein shown and described.
