structure 2 by means of screw-threaded hangers 33. A red is pivotally connected to the arm 81 and a spring 35 extends around that portion of the rod immediately above the plate 32 and bears at one end against the arm 31 while its other end bears against a plate 36, which is loosely mounted on the rod 34. and which is slidable on the hangers 33, there being nuts 37 engaging saidhangers and above the plate 36 whereby the said plate can be shifted for the purpose of increasing or diminishing the tension of the spring The rod 34 extends upwardly into the car structure 2, and constitutes means for transmitting motion from the depressible step to a register located at any suitable point within the car. By referring to Figs. 4, and 6, it will be seen that the register includes a casing 38 having a disk 39 mounted for rotation therein, there being ratchet teeth 40 upon one face of the disk and designed to be successively engaged by a spring-pressed dog 41 carried by the rod 34-. A. spring-pressed pawl 42 is mounted within the casing and back of the disk 39, and is designed to engage the teeth 40 so as to prevent return movement of the disk 39. The front face of the disk 39'is provided adjacent its periphery with numerals arranged in regular order and designed to be suocessively exposed through an opening 43 formed in the front of the casing. These numerals may range from 0 to 50 or from 0 to 100, and suitable mechanism of the usual or any preferred form may be utilized for transmitting motion from this disk to a second disk 44 on which hundreds may be indicated. Additional means of the usual or any preferred type may be provided for transmitting motion from disk 44 to' a third disk 45 on which thousands are indicated.
It is of course to be understood that each complete rotation of disk 39 is to produce a fraction of a complete rotation of disk 44, and that each complete rotation of disk 44 will produce slight movement of the disk 45. inasmuch as this mechanism is of an ordinary construction it is not deemed necessary to illustrate and describe the same in detail.
it is to be understood that the springs hold the treads of the steps normally elevated to their greatest extent, and with the lower edges of the heads and 12 above and out of contact.-with the u er edges of the projections 15 and 17. bpring 23 also holds the arm normally pressed-to one side, as indicated in full lines in Fig. 2, and the spring exerts a constant downward pressure upon the arm 31 and rod 34. hen a person entering the car places his weight upon the lower tread 7 said tread is de pressed, and inasmuch as the edge 16 is arged at one side of the edge on the promon 18, one of the beveled faces of the head 15 will operate to swing the projection '18 laterally so as to bring the edge of the .of said head and projection thus cooperate to complete the rocking mo'vement of the bar 19. Arm 27 will thus be further shifted in the direction of the arrow in Fig. 2, this movement being sufiicient to push the rod 34 upwardly such a distance as to cause the dog 41 to turn the disk 39 one tooth and to bring one of the characters on said disk into view through the opening 43 in the case 38. As soon as the we ght of the person is removed from the upper tread 8 the various springs of the mechanism will return all of the parts except the disk 89, to their initial positions. I
Should a person desire to leave the car by the same steps, his weight is first applied to the upper tread 8, but inasmuch as the upper edge of the projection 17 .is normally at the wrong side of the edge 13 of the head 12, it will be apparent that the downward movement of the said head 12 will tend to shift the pitman 22 so as to swing arm 25 in a direction the reverse of that indicated by the arrow in Fig. 2. Obviously therefore the register mechanism will not be operated.
As shown in Fig. 1, a supplemental stationary step 46 may be mounted on oneof the hangers 1 so as to permit" the conductor to enter or leave the car without operating the mechanism. Moreover, it is preferable to provide each of the treads 7 and 8 with a movable riser or apron 47, designed to close the spaces below and in front of the treads. It will be seen that mechanism such as herein described will accurately register the number of persons entering a car, andthe same will be found especially advantageous, because the same steps can be used both for ingress and egress, although the register mechanism will only be actuated by.. persons entering the car. lvloreovcr, the said mechanism will not be operated unless a person places his weight successively upon both steps of the car, and there is therefore no danger of the register being operated by persons standing upon the step.
Although the operating mechanism has been shown dependent upon the successive pressure of two steps, it is to be understood that if preferred more than two steps may be utilized for this purpose. Moreover, bv changing the relative positions of the rock bar and the depressible actuating .head, the
mechanism can be caused to operate'only when a person is leaving the car. The lip-.-
per tread easily can be locked against movement in any desired manner so as to prevent the mechanism fr'omactuatin the register.
is especially \Vhile the mechanism head designed for use upon street carsandthe like, it is to be understood that it can be-utilized at the entrances to theaters, amusement parks, and other places, where it is desired to keep a record of the number of persons entering.
Various changes can of course be made in the construction and arrangement of the parts without d-e arting from the spirit or sacrificing the a vantages of the invention.
' \Vhat is claimed i s:-
1. The combination with a register, and power transmitting mechanism connected thereto, of a rock bar, projections upstanding therefrom, yieldingly supported steps adjacen thereto, means extending from one of the steps for moving against one of-the projections to shift the rock bar and bring the other projection into a redetermined position, and. means extending from the other step and movable therewith for actuating the positioned projection to shift the" rock bar and actuate the power transmitting mechanism,
2. The combination with a register, and means for transmitting motion thereto, of a rock bar having projections extending jacent the bar, a stem pro ecting from one of the stops and movable against one of these i therefrom, yieldingly supported steps adprojections to shift the bar and bring the other projection to a predetermined position, and a stem upon the other step and movable against the positioned projection to shift the rock bar and the motion transmitting mechanism. I
3. In combination with a register, and mechanism for transmitting motion thereto, said mechanism including means for producing lost motion, of a rock bar, upstanding projections thereon, steps adjacent the bar, said steps being yieldingly supported, a deflecting head secured to and movable with. one of the..steps and against one of the projections to shift the bar and take up the lost motion in the motion transmitting mechanism, and a shifting head connected to the other step and. movable against the other projection subsequent to the shifting of the rock bar to actuate the rock bar and mechanism and the register. 4
t. The combination with a register, and
