`
`PEDOMETER.
`

`(No model.)
`
`To all who/21, it 72ta,7/ c07wc7=72,.-
`Be it known that I, EDMOND KUHN, a citizen
`of the United States, residing at East Orange,
`in the county of Essex and State of New Jer-
`sey, have invented certain new and usefullm-V
`proveinents in Pedometers, of which the fol-
`lowing is a specification, reference being had
`therein to the accompanying drawings.
`My invention relates to improvements in
`pedonieters of that class which are designed
`to be carried in the pocket or attached to the
`person of a pedestrian to register the distance
`traveled, and has for its object, among other
`things, simplicity of construction and fewness
`of parts, so designed as to be economically
`constructed and readily assembled, and, fur-
`ther, to provide means for adjusting the mech-
`anism for steps of varying lengths.
`To these and other ends myinvention con-
`sists in the pedometer having certain details
`of construction and coiiibinat.ion of parts, as
`will be hereinafter described, and more par-
`ticularly pointed out in the claims.
`Referring to the drawings, in which like nu-
`merals designate like parts in the several fig-
`ures, Figure 1 is a front view of the pedome-
`ter. Fig. 2 is a View of the int rior mechan-
`ism looking from the back, upon
`enlarged
`scale. Fig. 3 is an elevation thereof. Fig.
`4 is an enlarged sectional elevation of the regu-
`lating mechanism, taken upon lineA B of Fir’.
`2; and "Fig.
`is an end view of the vibratory
`lever upon
`large scale.
`In the drawings the numeral 1 designates
`the case, within which the mechanism is se-
`cured in anypreferred manner and having the
`usual ring 2 connected therewith.
`The pedometer may be carried in the pocket
`or fastened to the clothing by a pin, which can
`be secured to the back of the case.
`The interior inechanisin in part comprises
`a circular bottom plate 8, a top plate at of less
`width than the bottom plate, a bridge 5, at- '
`tached to the top plate by a screw 6, a vibra-
`tory lever 7, having a weight 8 upon its outer
`end and pivotally secured upon a spindle 9
`between the overhanging end of said bridge
`and top plate, a notched wheel 10, rotatably
`mounted upon the spindle 9 between the vi-
`50 bratory lever and top plate, a pinion 11 be-
`
`tween the said plates and fixed to the notched
`wheel 10, (see Fig. 3,) a "spring-finger 12, se-
`cured to the lever 7, the free end of which
`bears against the periphery of the notched
`wheel10, a stop-finger 13, attached to the top
`plate, which also bears against the periphery
`of the notched wheel and by engaging its teeth
`prevents movement thereof in one direction.
`The stationary position of the vibratory le-
`ver 7 is shown in Fig. 2, wherein the upper
`edge thereof is held against a fixed stop 14- by
`a spring 15, which is fastened at one end to
`the top plate by a screw 16, and the other end
`of which engages a shoulder 17 in the lower
`edge of the said lever adjacent to its pivot-
`Inounting. The weight Sis of greater thick-
`ness than the lever 7 and projects below the
`top plate 4:.
`(See Fig. 3.) This lever and
`weight may be made in one piece,if desired;
`but I find it more economical to make them
`of two parts, which are fastened together by
`any preferred means. As shown, a slot is cut
`in the upper surface of the weight and within
`which the end of the vibratory lever 7 is so-
`cured.
`Connected with the notched wheel 10 and
`the pinion 11 is a gear-train, comprising a
`gear 18, which meshes into the pinion 11, a
`pinion 19 upon the same spindle as the gear
`18, a gear 20, meshing into the pinion 1%] and
`fixed upon the same spindle as the pinion fl,
`and a gear
`2, mounted on the main spindle
`23 and meshing into the pinion 21. This
`spindle projects through the bottom plate
`and carries the units-indicating finger :24.
`The indicating-dials are either graduated
`upon the bottom plate 8 or a p ‘inted dial can
`be attached thereto,
`is common and well
`known in the art. A .ens—register is operated
`from the
`22, there being a pin £35 in one
`side of said gear
`ch engages the teeth of
`a pinion 26 upon a spindle 27 once during
`each revolution, and upon the said spindle 27
`is a tens-indicating linger 28, which rotates
`over the tens-dial 29. The proportions of
`the gear 22 and pinion 9G are as one to ten,
`so that every ten revolutions of the gear 22
`will impart one rotation to the pinion 26 and
`the tens-finger 28, as is corninon in counting
`, inechanisms.

`
`claim as new, and desire to secure by Letters
`Patent, is—
`1. In a pedometer, the combination witha
`vibratory lever; of an indicating-finger; a
`train of gears operated by the movement of
`said lever for actuating said indicating-fim
`ger; a fixed stop to limit the movement of
`said lever in one direction; and a cam-stop
`for limiting its movement in the opposite di-
`rection.
`
`The pedometer is actuated by the vibra-
`tions of the vibratory lever 7, which vibra-
`tions are in a vertical plane and result from.
`the shock to the body of the pedestrian as
`the foot strikes the ground. As the weight
`8 drops against the tension of the spring 15
`the finger 12 rides over the teeth in the notched
`disk 10, and when returning under the pres-
`sure of the spring 15 this finger 12 engages
`one of the teeth upon the periphery of the
`disk 10 and imparts to said notched disk a
`partial rotation, which rotation is communi-
`cated to the gear 22 and the units-indicating
`finger 24 through the train 0]": gears above. de-
`scribed.
`'
`To regulate the length of stroke of the vi-
`bratory lever, I have provided a regulating
`mechanism which comprises a cam-disk 30,
`having a pin-hole 34; therein, a notched disk
`.31, a screw 32, by which said parts are rota-
`tably secured to the top plate, and a click-
`spring 33, which is secured to the top plate 4,
`as shown in Fig. 2.
`In the drawings the cam
`30 and notched disk 31 are shown as being
`made of two separate pieces, but do not limit
`myself thereby, as they can be made integral
`with each other, if desired.
`It will be appar-
`ent that the location of the cam 30 about the
`screw 32 will lengthen or shorten the open
`space between the stop-pin 14 and the cam 30.
`As the lower edge of the vibratory. lever en-
`gages the cam 30 at the bottom of each stroke,
`the length of stroke of said vibratory lever is
`varied according to the position of said cam.
`Thecam is rotated by placing a pinor simi-
`lar thingin the pin-hole 34.an‘d is held in any
`of its adjusted positions by the click-spring
`33, the point; of which engages one of the
`notches in the disk 31.
`(See Fig. 2.) A scale
`35 is graduated upon the top plate 4, so that
`the cam may be adjusted to any predeter-
`mined position.
`There are minor changes and alterations
`that can be-made within my inventionaside
`from those herein shown and described, and
`I would therefore have it understood thatI '
`do not limit myself to the exact construction l
`herein shown and described, but claim all
`that falls fairlywithin the spirit and scope-
`5r> of my invention.
`Having described my invention, what 1

`vibratory lever; of an indicating -finger; a
`train of gears operated by the movement of
`said lever for actuating said indicating-fin-
`ger; a fixed stop to limit the movement of
`said lever in one direction; and a pivota1ly-se-
`cured adjustable stop for limiting its move-
`ment in the opposite direction, comprising a
`rotatably-mounted cam; and spring mechan-
`ism for holding said cam in any of its adjusted
`positions.
`.
`3. In a pedometer, the combination with-av
`vibratory lever 7; of an indicating-finger;
`a train of gears; a fixed stop 14 for limiting
`the movement of said lever in.one direction;
`arotat-ably-mounted cam 30 -for limiting the _
`movement of said lever in the opposite direc-
`tion; and a spring 33 having connection with
`said cam for holdingthe same in its adjusted
`positions.
`, 4. Inapedometer,the combination with the
`bottom plate 3; of the top plate 4 of less width
`than said bottom
`plate; a vibratory lever-7 ~
`pivotally secured above said top plate; a
`weight 8 fixed to -said lever and projecting
`below said top plate; a dial; an. indicating-
`finger; a train of gearsbetween the said plates,
`operated by the movement of". said lever and
`actuating saidindicating-finger; a fixed stop
`14 for limiting the movementof said lever in
`one direction; and an adjustable stop for _
`limiting its movement in the opposite direc-
`tion,,all constructed and operating.substan- _
`tially as described.
`In testimony whereof I affix
