To all trltont i! may concern:
lie it. known that l, BENJAMIN H. Cannon, of Hearlmrongh-on-the-llndson, in the county of \\'estehester and Htute of New York, have invented certain uewand useful im irovetneuts in ltalotneiers; and i do hereby eclnre that the following speeilit'ttliolt, when taken itt connection with the accompanying drawings, is such a full, clear, and exact descri iiiOll ofthe same as will enable others skilled in the art to umkc and use the same.
in said drawing, Figure 1 is a front elevation of tlte instrument, showing the cover of its case removed, in ortlerto expose the face of the registering-disk and indicator. Fig. 2 is a similar viewot'theinternaldrivingmechanism, which is attached to the back plate, the registering-disk and the parts carried by it being removed to expose the satne. Fig. 3 is a vertical sectional view taken on the vertical ecuterol' Figs. 1 and 2. Fig. 4 is an enlarged vertical sectional view ol'the registering mechnuisnt, tints showing the indicator, registeringdisk, its hub. the dill'ereutial wheels, and the fastening-spring. Fig. 5 is an edge elevation of the registering and drivingmechanisms, as adjusted in their operative positions. Fig. ii is a rear view of the registering mechanisms which are carried by tlte registering-disk, showing more particularly the mode of fastening the parts in place by means of the tint spring 22.
The object of this invention is to secure a more perfect operation of this class of instruments than has heretofore been attained; and to that ettd the invention consists in an improved construction of the parts and coatbinntions thereof, whereby distances walked over may be accurately measured and recorded, whether the. steps taken itt passing over the distance ittOitiLtl be lottg or short, all of which is too particularly hereinafter set forth to need further preliminary description.
The meehauismsnte all contained in a case, A, similar to n watch-case, which may be provided with a hook, pin, loop, or btttten for securing the instrumentto the person itt an upright position, and with n protecting-cover, l).
The actuating or driving mechanism is attached to and supported by a circular back plate, 1!, which is secured to the inner side of the back of the case A by means of screws passing through screw-holes 21 21.
The actttatiug weighted lever 1" is fulernmed upon a pivot which projects from the back plate, It passes through an arm 12 of the lever i0,and is llxed in place b abridge-piece, 13. The lever 10 iseounterba aneed by means ofa lmw-sprtng 1.3, which, seated ltt tlte end of an adJnstln deck, 16, is connected to the arm 12 of an d lever by alink, .l, and the power of this spring 15 is capable of regulation by means of the adlustnble block 10, which is slotted, so as to move to and fro over a fastening sctscrew, by which its position may be fixed. The preferable form of this block 16 is a swinging lever, as shown. The actuating wclghtul lever 10, which vibrates between limits constituted by the stop-plus 11 17, is tints suspended frotn the spring 15, whose )OWCI is a col) adjusted so as to overcome i to gravity of or balance the weighted end of said lever and hold it in its a t ermost. position against the stopplu 17, or ill its lowermost position against t it! stop-pin 11, us may be desired. Thislever 10 has projecting frotn its lowerside palatesfi 8, which are so shaped as to alternately engage the-teeth of a starwheel,4, accord ng assaidleveris in its uppermost or lowermost position, and when said lever is vibrated so act as to revolve said starwheel step by step. This star-wheel 4 is fast upon a stud, upon which is also fixed a drivin -pinion, 3, which latter en ages with and drtves the ditierential toothet wheels 1810 when said star-wheelie revolved, as will presently appear.
The registering mechanism consists of an indicator, 20, and a registering-disk, U, which devices are revolved in the same direction at ditiercnt speeds by means of the ditl'erentialtoothed wheels 18 10. The toothed wheel 18 is centered on the lntb 0, and tlxed to the rear face of the registering-disk U by means of a pin, 7, and hence the disk Uand wheel 18 may freely rotate togctbertumn the lutb i). This hubtl has a tiauged head, which rests upon the face of the disk (J, while its stem, project ing from the rear side thereof, is stepped, so as to form independent shouldered seats for the wheels 18 10. The toothed wheel 10 is secured to thelmb 9, so that the same shall revolve with it. h means at" n fnrlteil spring. 2;, the lilnhs nt' whieh enter a reeess ent in the stein ut' saiil huh near its inner end. tllltl hear npnn the little! tin-e nt' the heel lt while the elul at the sprin;, hasa right-angular sllul that engages in a hnhnnnle in the enter t'aee nt' suiil wheel in.
