I, REGINALD HADDAN, of the Firm of Herbert Haddan and Co., of
18, Buckingham Street, Strand, W.C. London, Patent Agent do hereby declare
the nature of this invention, a communication to,me from abroad by Henry Albert
Loew, Mechanical Engineer, of Cleveland, State of Ohio, United States of America,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement
The invention has for its object the production of a cyclometer which shall be
positive in its action; one in which there shall be a total-adder-wheel, a local
indicator dial or pointer traveling therewith but adjustable independent thereof,
and another dial or pointer independent of either of the above for indicating the
divisions of a mile; one in which the parts are small in number and simple. in
construction; and consequently a cyclometer not liable to get out of order. The
invention consists in a combination of devices and appliances bereinafter described
and claimed.
In the drawings;
Figures 1 and 2 are perspective views of a portion of a bicycle or velocipede-
wheel and my cyclometer attached thereto, the two views being taken from opposite
sides, respectively, of the wheel.
Fig. 3 is an elevation of the cyclometer, 'partly.in.setion.
Fig. 4 is an elevation, partly in section on line 4-4, Fig. 3.
Fig. 5 is an elevation, partly in section on line 5-5, Fig. 4.

Referring to the drawings, A represents the hub of the wheel of a bicycle.or
velocipede B the spokes thereof, iC the standard or fork ;D the nut onlan.end
of the wheel-axle. E designates the supporting-arm of my cyclometer provided
with a slot e.engaged by the axle. It is obvious that by removing nut D and
slipping arm E onto the axle, and then replacing the nut, the cyclometer is held
firmly in place. The end of arm Exterminates in two arms E, F,represents
a metallic frame or supporting-piece that is provided with two slides ƒ engaging
islideways or guides: formed in and at or near the free ends of arms and E³,-
which engagement is perfected by the sorew Gextending from arm to arm and
engaging corresponding holes in. said arms and by which construction the body of
the cyclometer may be adjusted relative to the spokes of the wheel.. H designates
a suitable bearing carried by or formed in the supporting-piece F, and J.represents
aworzn-shaft extending through the same (see Figure 3) and provided on its end
with a sprocket-wheel J. A spring Jis provided to: increase the friction and thus
prevent wheel from moving more than the desired' distance: Carried by the
spoke of the wheel is an arm. K engaged to the spokes by the plate, and screws k²,
the plate and arm K-forming a clamp to engage a spoke and between which the
spoke is clamped, and the extension K¹ of the arm forming a bearing against the
adjacent spokes to prevent a rotation on the spoke. Carried by the arm is a
finger Kwhich as wheel A revolves, engages the sprocket-wheel J and moves the
latter one notch or tooth: Thus for every revolution of the bicycle or velocipede-
wheel the sprocket-wheel Jis moved one tooth or notch.
K
Meshing with the worm Jis a gear M. Said gear M, together with the dial M',
are mounted upon the worm-shaft, N, the gear M being held thereto by,the, spring
washer m and the screw.m'. Meshing with the worm N are two gears P, P.
These gears are mounted upon the shaft Q, the gear P. being integral with or
"

engaged to the shaft, while the gear Pl revolves thereon. Engaged to the shaft Q,
by the friction washer y and screw 9, is a dial or indicator R. The gear P is
provided with, we will suppose, one hundred teeth, while the gear P' is provided
with one less, or in this case ninety-nine teeth. On the face of the supporting-
piece is a pointer; arrow or indicating mark and the rim of the dial R is
provided with graduations r, the rim in this case being so graduated that each
mark represents one mile. It will be seen by the foregoing description that the
dial M and the dial R are both loose on their respective shafts but are held thereto
by friction washers so that the dials can be revolved and set at any particular
point independent of their respective shafts. It will also be observed that by
virtue of the fact that the gear P has one less, tooth than gear P, said gear Pi
will, upon, one revolution of the dials, gain one tooth in position; consequently by
graduating the face of gear Pto form a dial, each mark to represent one hundred
miles, the total number of hundred miles traveled by the machine will be registered,
and by graduating the face of gear P to form a dial,, so that each tooth upon said
gear
P shall indicate one mile, any remaining fraction of a hundred miles is
indicated by a pointer Frigid with supporting-piece Fi
"
I will now explain the operation. Member K2 of arm K on the wheel, at each
revolution, will strike a tooth or sprocket on the sprocket-wheel J' and revolve it a
corresponding distance. This revolves the worm J which in turn révolves the
gear M and dial M'. This dial M', as will be seen in the present case, is divided
into the graduations of a mile, so that one revolution of this dial M represents a
miles travel. A pointer F³, carried by the case, serves as an indicator. The
revolution of the shaft N, on which the gear M is mounted, revolves the
gears P, P', and the revolution of the shaft Q on which these gears are mounted
revolves the dial R. Consequently, for every revolution of the gear M and the
dial M', the gears P, Pare revolved one, tooth or graduation, thus indicating on
the dial R the number of revolutions of the mile-dial. M. Now, by the difference
in the number of teeth on the gears P, P, every complete revolution of the gear P
will be indicated on the gear P through the hole, opening p.in.gear P, and which
hole is suitably shaped to form an indicator. If at any time, the rider desires to
set the mile-dial M³ to zero, or the one-hundred-mile-dial R to zero, he has only to
revolve them to the proper points, keeping the total number of miles traveled by
the machine on record by the dial P.
It is obvious that various details of my device might be altered. For instance,
the dials M', R, might, instead, be pointers with. fixed graduated dials on the case.
So, also, the dial M¹ might be dispensed with, and, the distance traveled could be
recorded
oni the dial R.

:
These various changes, and others, might be made without departing from the
spirit of my invention which consists, primarily, in the provision of two gears, Pi
and P', one gear having one less notch or tooth: than the other, and the indicator,
such as dial R, adjustable independent. of said gears, but ordinarily traveling
therewith.
:
So also while I have herein spoken of the gear Phaving one less tooth than the
gear P yet it is obvious that the gear P¹ might have one more tooth than the
gear Pand such a variation I would be understood as covering by my claims.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
