AUTOMATIC PASSENG ER-REGISTER.

SPECIFICATION forming part of Letters Patent No. 468,845, dated February 16, 1892.

' Application filed February 2, 1891. Serial No. 379,895. (No model.)

- the following is a full and exact description 1 thereof, reference being had to the accom panying drawings, and to the letters of reference marked thereon, making a part of this My invention relates to automatic registers for indicating the number of persons passing through a gateway or in agiven pathway, and has for its object to produce automatically by. the action of the weight of each individual walking over the apparatus in either direction a movement of an indicating and'counting apparatus, which shall register the fact positively and with certainty.

It consists in the combination and arrangement, in connection with any suitable form of indicating mechanism, of a series of pedals and operative devices connected therewith,

" n of Similar letters indicate like partsv in the figures. t

A AA and l3 B B are a series of parallel pedals of any suitable widths placed closely side by side to form unitedly a continuous sectional platform to be placed in the way through which the persons to be counted are to pass, the pedals being disposed at right angles to the line of travel.

The two series of pedals A and B are disposed on either side of a central division-line W, (see Fig. 1,) and operate, respectively, as hereinafter described, to indicate the number of travelers crossing the line Win the one direction or the other.

An independent ratchet-Wheel G is provided for each pedal.- The ratchet wheels connected with the pedals A A on one side of the division-line \V are all fixed upon one horizontal shaft J, and those connected with the pedals B B, on the other side of the line, are fixed upon a corresponding shaft J, these shafts being mounted to rotate, in suitable bearings upon a frame-work H at a suitable height above the pedals.

Each pedal is upheld at its inner end by a spring 0 placed under it, and this uplifted end is coupled by means of two links E E with independent pawl-arms F F, pivoted to oscillate upon the axis of the ratchetwheel appropriate to the pedal, one on each side of the wheel.

Each ratchet-wheel is formed with a double set of teeth formed side by side upon its periphery, yet all inclining in the same direction. The intervals between the teeth in each set are equal, but the several teeth are so disposed as that those in the one set break joint with those in the other midway of each interval.

The two pawl-arms F F for each pedal extend radially in opposite directions from their common axis on opposite sides and beyond the periphery of the interposed ratchet-wheel G. Each pawl-arm is fitted with a spring-actuated pawl I, (see Fig. 2,) adapted to engage vtuatin g it as that when the pedal is depressed itwill operate to carry the ratchet-wheel forward one step-viz., one-half the length of a tooth-and by reason of the arrangement and connection of the two pawls F and F with the one pedal A (01113) the depression of the pedal will thus operate to carry the ratchetwheel forward one half the length and its elevation the other half of the length of a tooth in the same direction.

Since all the ratchet-wheels on each side of the division-line \V are fixed upon the same axial shaft J or J, it follows that when either of the ratchet-wheels G on the shaftis turned one step, or one-half the length of a tooth,by the depression of a pedal it will turn all the other wheels on the same shaft. Hence if after the wheels have thus been moved one step a second pedal under the same shaft be depressed before that which was first trodden upon and depressed has been allowed to rise, the depression of the second pedal will have no effect, since the tooth actuated upon by its pawl will have been already moved forward one step, or the half-length of the tooth, and the pawl will consequently simply move idly forward against it. Thus a second movement of the shaft J and the cam-wheel K carried by it can be effected only by the elevation of a pedal after the first movement of the shaft has been produced by the depression of a pedal, and the depression of a second pedal actuating the same shaft will have no effect thereon unless in the meantime the first pedal has been elevated. A false double movement of the cam-wheel operating the indicating mechanism is thus effectually prevented, and said mechanism will be operated only by the depression of a pedal on one side of the division-line after the depression of a pedal on the opposite side thereof.

Each pawl-arm, beginning with that in each set nearest to the division-line V, is formed with a lateral offset or projection I), (see Fig. 1,) adapted to overlap a similar projection 11 on the pawl-arm next to itin order, so that the depression of any one pedal in each set other than the first or outer one will operate to depress not only its own pawl-arm but also each of the pawl-arms between it and the outer end of the series without, however, influencing those in advance of it between it and the division-line The two shafts J and J are mounted in par: allel lines with their inner ends terminating in the plane of the division-line V at such distances apart as to permit securing upon said inner ends cam-wheels K K of greater diameter than the ratchet-wheels, a sufficient interval being also left between the peripheries of said wheels to allow of the interventionof the gear-wheels and coupling device for an indicating mechanism L, as hereinafter-described.

The cam-wheels K K are all alike peripherally notched toproduce a succession of double or two-faced cams, one face of each double cam being on the periphery of the wheel, as at c d, Fig. 2, and the peripheral and the lateral inclination for each cam being made to correspond exactly. The number of these cams on each cam-wheel corresponds with that of the teeth in each ratchet on the ratchetwheels G G.

The cam-wheels K K are preferably so mounted that the lateral cam-faces a b on both shall face in the same direction and revolve in a plane coincident with that of the division-1ine V, as shown in Fig. 1. Midway between said cam-wheels a vertical spindle M (see dotted lines, Fig. 2 is mounted upon a cross-bar H of the frame H, and a sleeve N is fitted to revolve freely upon this spindle. A disk 0 is secured horizontally upon the upper end of the sleeve N to revolve with it, the spindle being so proportioned in height as to bring the disk 0 upon a level with the axes of the cam-wheels, as shown in Fig. 2. A coupling-bar P is mounted to slide longitudinally in suitable ways formed diametrically upon the disk 0 to project beyond its periphery far enough in each direction to admit of engagement at each end with the cams on the cam-wheels K and K. This horizontallysliding coupling-bar is automatically centered upon the disk by means of springs 7' r, secured to the sleeve N, and whose free ends project through slots in the disk 0 into engagement with the bar P.

Immediately above the disk 0 are mounted two pinions S and T revolving upon a common axis coincident with the axis of the spindle M, the one S upon the lower end of a spindle S geared to and depending from an indicating mechanism supported upon a cross-bar ll of the frame-work of the machine and the other T upon the lower end of a tubular shaft T encircling the spindle and geared to a second indicating mechanism carried with the first upon said cross-bar 11*, the two indicators being inclosed in a common case L. (Sec Figs. 2 and 12.)

The sliding bar P is fitted at one side of its central point with a short pin a, adapted to engage the notches in the pinion S when the bar is moved from its central position in the one direction, and on the opposite side with a second longer pin o, adapted to engage the notches in the pinion T when the baris moved from its central position in the opposite direction. The pins 11. and v thus serve, respectively, to couple the bar with the one pinion or the other, according to the direction in which the bar is moved.

The sliding coupling-bar P is so proportioned in length that when in its central or balanced position its ends will be respectively in close proximity to the inner re-entrant portion of one of the peripheral cams c (l on each of the cam-wheels, and consequently likewise opposite the lateral, inner, or re-entrant portion a Z) of the corrcspondinglateral cam. \Vhen in this position, the first mole of either cam-wheel produced by the depression of either of the pedals coupled thereto, by operating to move a cam forward one'half position. bar may be returned to their normal central of its length, will carry the peripheral face of the cam against the end of the sliding coupling-bar P, and thereby move it lengthwise far enough to cause its pin it to engage the .pinion S on the indicator-spindle, the increase in the width of the face of the cam as it moves forward being sufficient to enable it to obtain: a bearing against the end of the bar directly after the movement of the cam-wheel begins. When the first movement of a cam-wheel, as K, produced by the depression of a pedal, as A, is completed, the peripheral cam will remain in contact with the sliding bar in position to hold it in engagement with the pinion of the indicator, as shown at the left in Figs. 3 and 6, and when the pedal is elevated by the withdrawal therefrom of the travelers foot the second movement of the cam will carry it beyond the end of the bar, as shown at the right in Figs;3 and 6; but since the pedal A after it'has been depressed cannot be elevated until the traveler has put one I foot down upon a pedal B on the other side of the division-line W, and since this forward foot will bear down said pedal B before the hinder foothas been freed from the first pedal A, the pedal B, actuated by the forward foot, will operate to turn the opposite cam-wheel K one move, during which. the lateral face of the cam in contact with the proximate end of the coupling-bar P will force the bar laterally, (see Fig. 7,) and by causing it to turn upon its pivot will operate to turn the pinion S with which the bar is engaged and thereby move the indicating mechanism one step. By the time this swinging movement of the coupling-bar P is completed the cam-wheel K at the opposite end of the bar will have completed its movement produced by the release of the first pedal A, so that the barwill be free to spring back to its normal central (See Figs. 1 and 2.) The disk and position with respect to their oscillations by any suitable spring, such as that shown at :0 in Fig. 12. Thus the tread of the person appreaching the division-line W from either direction will operate, first, to carry the coupling-bar into engagement or gear with the in dicating mechanism, and as the person passes from one side of the line W to the other will operate to swing the coupling-bar around far enough to move the indicating mechanism one step, the automatic elevation of the pedals after their depression operating to restore the coupling-bar and the cams actuating it to pawl, as shown in'Figs. 8 and 9, instead of by double pawls, as shown in Figs. 1 and 2. Where but a single pawlis used, adepression alone of the pedal operates the ratchetwheel and the cam-wheel connected thereto, and the wheels make a full stroke at each forward movement. In such case the ends of the peripheral cams on the cam-wheels K are undercut, as shown at e e, Figs. 8 and 9, and the contacting. end of the coupling-bar P is enlarged at its outer end and beveled off inwardly to form a tooth f, adapted to pass laterally into the recess 6, formed by the undercut portion of the cam. This enlargement of the outer end of the coupling-bar P operates to prevent the bar from slipping off of the end of the cam when the cam-wheel has completed its stroke and thereby forced the bar longitudinally inward, as shown in Figs, 9 and 10; but after the bar has been swung over upon its pivot to clear the cam, as shown in dotted lines in Fig. 1-1, and carried outwardly longitudinally by the action of its spring r, as shown by positive lines in the same figure, the hook f will be in position as the bar is swung back to its first or normal position (shown in Fig. 8) to pass without interference into the under-cut c of the cam and against the face of the peripheral cam in readiness to be again forced outward by the next movement of the cam-wheel.

As a further modification, the coupling-bar P may be provided with pins u u to engage severally the same toothed wheel S from diametrically opposite directions, so that when the bar is carried longitudinally by the one cam-wheel or the other it will be brought thereby into engagement with the one toothed wheel S as shown in Figs. 8 and 11, instead of with independent pinions S and T, as shown in Figs. 2 and 3. In such case the toothed wheel will be turned in opposite directions by suitable gearing, which need not herein be described, to actuate one indicator when it turns in one direction and another indicator when it turns in the opposite directions.
