PROVISIONAL SPECIFICATION.
Improved Engine Speed Counter and Register.
I ARTHUR KING, Pinxton, near Alfreton, Derbyshire, Engineer do hereby declare
the nature of this invention to be as follows:-
Each speed counter and register consists of the following parts, the engine shaft
or beam is provided with a projecting cam which at each stroke of the engine lifts a
rocking lever, having one end connected by a link to a rocking shaft carrying
a clawker which moves a ratchet wheel tooth by tooth, this wheel is interchangable,
each wheel having as many notches as the engine is required to revolve per minute,
the ratchet wheel axle is provided with a projecting wing its whole length between
the bearings, at each entire revolution of the ratchet wheel the wing operates a
rocking lever, provided with a weight and piercer which perforates a checked paper
at each movement, the axle of the rocking lever is screw threaded to receive the
screw threaded boss of the lever which is provided with a suitable shaped escapement
operated by clock work, which also revolves the cylinder carrying the checked paper
before named, the escapeinent allows the lever carrying the piercer to be traversed on
its screw threaded axle to the next row of checks on the paper. By which means
the speed of the engine is counted and registered every revolution of the ratchet
wheel.

COMPLETE SPECIFICATION.
Improved Engine Speed Counter and Register.
1 ARTHUR KING, Pinxton near Alfreton Derbyshire Engineer 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1, shows a front view of an improved engine speed counter and register
applied to an ordinary clock, with the face removed to show more fully certain parts
referred to, the studs which support the face are shown only at Figure 1.
Figure 2 shows a back view of the speed counter and register.
Figure 3 a left side view of the same and
Figure 4 shows a ratchet wheel axle, and a screw threaded axle, in section together
with a side view of a weighted rocking lever, each severally referred to hereafter.
Each speed counter and register consists of the following parts, the engine shaft
or beam is provided with a projecting can or stud which at each stroke of the engine
lifts a lever A, which rocks on a stud B, projecting from the back bearing plate of
the clock, the upper end of the lever is slotted to allow of the adjustment of an axle
pin A carrying a clawker or driver A³, which moves a ratchet wheel C tooth by
tooth, this wheel is interchangeable, each wheel having as many teeth as the engine
shaft is required to revolve per minute, the wheel shown has sixty three teeth.
The axle D of the ratchet wheel revolves in the front and back bearing plates of
the clock, and is provided with a projecting wing D', nearly its whole length between
the bearings, at each entire revolution of the ratchet wheel, the wing raises a rocking
lever E into the position shown at Figures 2 and 3, the lever E is provided with a

page_text: weight and piercer E¹ at its outer end, and a spring E' on its underside which with-
draws the piercer from a checked paper H after it has perforated the same, the
checked paper is shown only at Figure 3.
The axle of the rocking: lever is screw threaded, to receive the screw threaded
boss of the lever, the back end of the axle has a pulley F¹ secured on it round which
a cord F is wound provided, at its. lower end. with as weight "not shown in the
drawings" the front end of the axle is formed-square-to receive. a. handle by which it
may be turned to wind up the cord and place the rocking lever E near the back end
of the axle.
The front end of the axle carries a lever provided with a stud F which is retained
in the position shown at Figures 1 and 3 by one of two inclines on the outer end of
a lever G, rocking on a stud secured in the front bearing plate, a spring G¹ screwed
to the plate presses on a stud projecting from the lever and holds it with the lower
end resting on a stud G2 in the bearing plate, except when raised by a pin G³ pro-
jecting from the hour wheel of the clock, the pin once in every hour raises the lower
end of the lever and lowers the inclines into position to allow the stud F³ to pass
between them, and make one revolution at the end of each hour and be again
retained by the incline, each revolution of the axle moves the lever to the right to
place the piercer E¹ over the next column of checks.
The checked paper H is divided and numbered horizontally into twenty four
columns to represent the hours, each column being divided into sixty squares, each
representing one minute.
The checked paper is carried by a flanged cylinder H each flange is provided with
a spring clip H which presses upon the edges of the paper, and hold it in position,
the axles of the cylinder revolve in the bearing plates, the front end carries a
wheel H3 of the same diameter and number of teeth as the main wheel H* of the
clock which drives it: :
.
A counter constructed as above described can be set to work at any given speed of
the engine, and will produce a perforation with certainty on the completion of a
required minutes work.
If therefore the engine runs the required speed, a perforation will be made in each
space regularly throughout. If the speed of the engine is from any cause reduced
or increased the perforations will be made irregularly and at once detected, the checked
paper showing distinctly any slowing down of the engine, and any racing to make up
the deficiency, and the time such occurs.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
The construction and employment of a screw threaded axle F with a pulley F¹
and weighted cord F at one end, the other end carrying a lever provided with a
stud Fa retained by a lever G carrying inclines which allow the stud F to pass
through at the completion of each hour when the lever is rocked by a pin G³ pro-
jecting from the hour wheel of the clock employed, by which means an immediate and
complete, traverse of a lever E provided with a weight and piercer E¹ is made to the
next adjoining, column substantially as described and illustrated in the drawings
annexed.
