I, WALTER WHITNEY HASTINGS, of No. 51 Clinton Avenue Jersey City, in
the County of Hudson, and State of New Jersey United States of America,
Superintendent for New York Standard Watch Company, 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 cyclometers and the chief objects of my
improvement are economy in construction and general efficiency of the machine.
In the accompanying drawing-
Fig. 1 is a front elevation of my cyclometer.
Fig. 2 is a front view of the same with the cap and dial removed and the case for
the screw shown in longitudinal section.
Fig. 3 is an enlarged sectional view on the line of Fig. 2, some of the parts
being shown in elevation, together with a part of a bracket arm, and
Fig. 4 is a sectional view on the line y y of Fig. 2 the other parts being in
elevation and the dial and cap omitted.
A designates the main case having a cap consisting of the sash or bezel 5 and
glass 6. At one edge of the case is the screw case 7 containing the worm or
screw 8 one end of which projects from the screw case 7 and is provided with the
driving arms 9. Within the screw case 7 is a friction spring 14 Fig. 2, for the
purpose of retaining the screw against accidental movement.
The back side of the case A is provided with two clamp plates 10 and 11 and
the screws 12. The plate 10 is fixedly secured to the case and may be provided
with a socket as at 13 while the plate 11 is movable as in similar clamps.
Within the main case at its edge is the annular toothed ring 15 which rests upon
a shoulder formed on the inside of the case as shown in Figs. 3, and 4, with its
teeth engaging the worm or thread of the screw 7 whereby a movement of said screw
will move said ring. This ring may be held to its seat in any proper manner as by
screws or pins in the side of the case as at 16. A stud or post 17 is mounted on
said ring so as to move with it, the outer or front end of said post carrying an index
er pointer 18. The body of this post or stud serves as a driving projection for
engaging the teeth of the wheel 19. Said wheel is provided with ten teeth or
projections for being engaged by the post or stud 17. It is mounted on the tubular
shaft or sleeve 20 which also carries a numeral disc 21 bearing on its front side the
uine digits and a cipher. The wheel 19 also carries a driving stud or projection 22.
The tubular sleeve 20 turns loosely on one of the fixed studs 23, the front ends of
which studs are bored and threaded to receive dial screws 32. A similar stud 24 is
in the middle of the case and on said stud is another tubular shaft or sleeve 25
carrying another ten toothed wheel 26, driving projection 27 and numeral disc 21,
while one of the studs 23 supports the third sleeve 28 which carries a ten toothed
wheel 29 and numeral disc 21. In a plane running diametrically through the case
at right angles to the plane passing through the studs 23, there are two studs 30
which with the studs 23 form a suitable seat for the dial 31 which is secured by
screws 32. The diameter of the dial is less than the inner diameter of the case so
as to leave room for the body of the stud 17 which carries the index 18 to move
around the outer edge of said dial.
In addition to the foregoing, it is desirable but not essential to add a spring or
springs 34, having upwardly projecting ridges 35 that bear upon the lower ends of
the several tubular sleeves 20, 25 and 28 said lower ends having ten radial grooves
to correspond with their ten periods of rest. When one spring answers for the

page_text: three sleeves it may be a simple strap or leaf spring with three perforations to
permit the three posts 23, 24 and 23 to pass through it while the ridges 35 are
formed immediately by the sides of said perforations.
The cyclometer may be secured by means of the clamp to any suitable support on
any kind of a vehicle or machine where the number of revolutions of any wheel or
shaft are to be counted, and in such a position as to have one of the screw arms 9,
struck by a projection on said wheel or shaft to move the screw a fraction of a
revolution for every revolution of said wheel or shaft. The support of the cyclo-
meter may be any convenient part of the machine upon which it is used or it may
be attached to the bracket arm 33, which arm is in turn attached to said machine.
The operation of the machine is substantially the same as in other cyclometers.
When used for measuring distances as traversed by a vehicle the screw and toothed
ring may be so mathematically laid out with reference to a vehicle wheel of a
certain size that one revolution of the ring will represent one mile. The screw
drives the ring 15 which ring once in each revolution moves the wheel 19 one
tenth of a revolution by the stud 17 engaging the teeth of said wheel while by means
of the driving projection 22 on wheel 19 the wheel 26 is driven one tenth of a
revolution for every revolution of the wheel 19 and the wheel 29 by means of the
driving projection carried with wheel 26 is driven one tenth of a revolution for
every revolution of said wheel 26, the dial being provided with openings through
which one of the characters on the several numeral discs is shown as in other
counting machines. In order to insure accuracy in operation I so arrange the parts
that all the numeral discs are moved by a driver that describes a larger circle than
the diameter of the wheel which is driven thereby. Thus the circle described by the
stud 17 is greater than the diameter of the wheel 19 which it drives, the circle
described by the driving projection of the wheel 19 is greater than the diameter of
the wheel 25 which it drives and the circle described by the driving projection 27
is greater than the diameter of the wheel 29 which it drives.
When the spring 34 is employed the movement of each sleeve has a tendency
through the bevelled sides of the ridges 35 and grooves in the lower ends of the
sleeves to force said ridge downwardly and permit the sleeve to make its fractional
part of a revolution.
When this movement approaches completion the summit of
the ridge enters the next groove with all the force of the spring thereby not only
preventing the numeral discs from being moved too far but also having a tendency
to carry them to a definite point and complete their movement in case the driving
projection did not carry them quite far enough. The spring will then act to hold
each sleeve and connected numeral discs in its position until the next forward move-
ment thereof as before described.
By my improvements the parts not only operate smoothly and accurately but the
parts are of simple and comparatively inexpensive construction and they are in a
very compact form.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is ;-
The combination of the case A the tubular toothed ring seated in the case at its
edge means for rotating said ring with an intermittent movement the stud 17
and index 18 carried by said ring the several numeral discs with their driving
wheels and projections mounted on said case inside of said ring the body of the
stud 17 serving as the driving projection for the first of said wheels and the dial
inside of the circle described by said stud 17 substantially as described and for the
purpose specified.
