`
`SPECIFICATION forming part of Letters Patent No. r758,4:05, dated April 26, 1904.
`Application ?led August 20, 1903; Serial No. 170,215. (No model.)
`
`To all whom it may concern.
`Be it known that we, O'rro BARTEL, residing
`at Manhattan borough, New York city, in the
`county of New York and State of New York,
`and EDMOND KUHN, residing at East Orange,
`in the county of Essex and State of New Jer
`sey, both citizens of the United States, have »
`invented new and useful Improvements in
`Pedometers, of which the following is a speci
`?cation.
`The object of this invention is to provide a
`pedometer of simple construction, its setting
`being accurate, with means to show the amount
`of setting required for the various sizes of
`steps. Furthermore, it has simple means of
`adjusting the tension of the spring which lifts
`the pendulum, which is of importance in ad
`justing the correct working of the pendulum,
`being adapted to overcome the variation of
`the parts referred to when manufactured.
`This invention is set forth in the following
`speci?cation and claims, and illustrated in the
`annexed drawings, in which‘
`Figure 1 shows the pendulum of the pe
`dometer with adjacent parts. Fig. 2 is a section
`along 5 5, Fig. 1.
`Fig. 3 is a section along.
`6 6, Fig. 1. Fig. 4 shows a bridge; Fig. 5
`, shows a pendulum-arm ‘partly ?nished. Fig.
`6 shows a pendulum-weight.
`'
`In the drawings is shown a base or frame
`plate q, with bridge 0, bearing a pivot (Z for
`pendulum a. This pendulum is readily formed
`from a sheet-metal blank, Fig. 5, with ?ange
`a’ and point or index-?nger (K. The flange
`(0’ is bent over to serve for the set-screw m to
`bear thereagainst or limit the play or swing
`of the pendulum between such screw in and
`stop or ?xed stud i. The function of pointer
`a2 will be presently explained. The pendu
`lum carries a spring or pawl 70 for ratchet
`,wheel a. A suitably cut and bent part a3 of
`the pendulum forms a ?ange or attaching part
`for the spring in. As the pendulum vibrates
`this pawl gives a step-by-step rotation to
`wheel 0 and thence to the pedometer-train.

`(Not shown.) The spring Z prevents retro
`grade rotation of the ratchet-wheel. The pen
`dulum has astud or pin f, against which bears
`spring g, which lifts or holds the pendulunror
`its flange (0’ to screw m. This spring is braced
`or secured in a stud 71, which is seated what
`may be called‘ “friction-tight” in plate q—
`that is, the- stud it can be rotated by a tool,
`(such as a screw-driver or other means, but is
`so tight in its seat as not to turn under any ten
`sion of spring 9. By setting or turning fric
`tion or rotary stud it one way or another the
`tension or action of spring g on the pendulum
`or pin‘ f is regulated. The screw m can be
`set or adjusted in the tap or stud n. The scale
`3), in connection with the index or pointer (42,
`already named, and the screw m, serve for the
`setting of the device or pendulum, according
`to the size of the steps made by thev person
`carrying or wearing the device.
`The pendulum a has the weight Z) secured
`thereto in any suitable way. As the pendu
`lum is vibrated by the march or movement of
`the'user the ratchet a and other parts are ac
`tuatcd.
`The friction-stud h is adapted to be engaged
`by a tool for setting the} spring g, and the
`pointer 602 with scale 1) enables accurate set
`ting or regulation of the pendulum, or rather
`its vibration or arc of oscillation. The spring
`9 sits against the cylindrical stud f with but
`slight if any friction, so that the pendulum is
`sensitive or responds readily to each step.
`7 The bridge, as seen in Fig. 4, can also be
`cut and bent froma single piece of sheet metal
`to form a bearing for wheel 0 and attaching
`?ange for stop or spring Z.
`What we claim as new, and desire to secure
`by Letters Patent, is‘~
`’
`1. Apedometer comprisinga pendulum pro
`vided with a pointer and a ?ange, a scale for
`the pointer, and a micrometer or set-screw for
`the ?ange.
`2. A pedometer having a pendulum the arm
`_ of which is stamped or formed from sheet

`3. A pedometer having a pendulum the arm
