IMPRGVEMENT IN ELECTRO-MAGNETIC REGISTERING APPARATUS FOR TURNSTILES.
Specification forming part of Letters Patent No. 9236 1, dated June 26, 1877; application filed March 30, 1877.
, To all whom it may concern with suitable mechanical devices, and a suit-- able registering mechanism, for the purpose of registering the number of persons entering or leaving a bridge, ferry, hall, room, or other inclosure.
In the drawing, Figure 1 represents a plan or top view of my improvement, partly in sec tion. Fig. 2is a longitudinal vertical section. Fig. 3 is a side view of the dial-plate and its frame.
My invention is described as follows: At the entrance of the ferry, bridge, or inclosnre is placed a turnstile consisting of a revolving vertical shaft, A, provided with four arms, b, so situated with regard to each other that a person entering from either side of the entrance shall push against one of said arms I) and cause the shaft A toperform one-quarter of a revolution. The upper part of the shaft A passes through a suitable frame-work made so as to support a circular disk, B, of wood or metal, which turns loosely on shaft. A. Directly above the disk B, and in contact with it, is a smaller circular disk, 0, which is fixed to and turns with shaft A. This disk 0 has a portion of its periphery cut into cogged teeth, which engage with corresponding teeth of a pinion-wheehc, which is vertically secured to the lower and larger disk B. The object of the cogged teeth on disk 0 and the pinionwheel 0 is to prevent the registering mechanism, which will be hereinafter described, from registering until the shaft A has performed nearly one-quarter of a revolution, thus preventing the registering mechanism from acting on any slight movement of the shaft A, and doing away with any tendency to accidental registration.
The pinion-wheel c is provided also with a pin, cl, fixed horizontally to it, which pin (1 strikes against either of the two pins, (1 or (Z secured vertically to the disk 0.
The object of these pins 01 d d is to save the cogs on the disk 0 and on pinion c from excessive strain or wear. A
On the periphery of the large disk B, fixed horizontally, is a pin, 6, which, as the disk 8 is made to revolve with shaft A, at every quarter of a revolution of shaft A, strikes against a button or circuit-closer, D, D D and D which are placed at proper distances apart and around the disk B. These circuit-closers are connected by a wire, f, with each other and with one of the poles, g, of a galvanic battery.
The disk B is connected with the other pole, h, of the battery, by means of the button or circuit-closer f, to which is connected the wire 70, which passes through the electro-magnets G and G and thence to the pole h.
Working in connection with the electromagnets G and G is the armature H, to which is secured a vertical lever, L. Attached to this lever L is one end of spring m, which has its other end secured to a standard, a. (See Fig. 2.) At the upper end ofthe vertical lever L are two pawls, O and P, one of which pawls, O, is secured to one side of the vertical lever L by screws or other suitable means, and the other pawl, P, is pivoted to said vertical lever L through a slot cut in. its top, and is sup ported by a spring, 19, placed under it.
These pawls engage with the teeth of the ratchet-wheel R. The object of these pawls O and P is to communicate a rotary motion to the ratchet-wheel R, and at the same time to prevent the ratchet-wheel R from moving more than the space of one of its teeth at one motion. The ratchet-wheel R is attached to a shaft, R, to which is fixed a registering indexhand, S, which moves around the face of a dial-plate, S, which dial-plate is furnished with a suitable index for registering the number of persons entering or leaving the ferry, bridge, or other inclosure. In connection with the ratchet-wheel R is a pawl, T, the purpose of which is to prevent the ratchet-wheel R from turning back after having moved the space of one of its teeth.
The shaft B may be provided with a pinion, to which may be attached suitable mechanism for registering up to'any number desired.
The operation of my invention is as follows: When a person enters the entrance-way where the turnstile is placed and attempts to pass the turnstile he imparts motion to the shaft A, and as he passes through causes it to perform onefourth of a revolution. The movement of the shaft A turns with it the circular disk 0, fixed to the shaft A. The motion of the disk 0 is communicated by means of the cogged teeth out in, and one of the pins (1 or d fixed to said disk 0, to the pin 01 on pinion-wheel a, secured to the disk B. The circular disk B is thus caused to revolve. This movement of the disk B causes the pin 6, projecting horizontally from the circular disk B, to strike against one of the buttons or circuit-closers D, D D or D arranged at proper intervals around the disk B.
A current of electricity then immediately passes from the pole g of the galvanic battery through the wire f, and through the disk B and button F, and thence through the wire K to the electro-magnets G and G. The passage of the current of electricity immediately causes these magnets G and G to attract the armature H. The attraction of the armature H to the electro-magnets G and G causes the lever L to move and the pawl P, connected with it, to engage with one of the teeth of the ratchet-wheel R, and to move the said ratchetwheel B the space of one of its teeth, and imparts a rotary motion to said ratchet-wheel B.
The movement of the lever L also causes the pawl O to engage with the teeth of the ratch etwheel R, and prevents it from moving more than the space of one of its teeth at one motion of the armature H and lever L. At the same time the movement of the pawl T prevents the ratchet-wheel R from turning back after having moved the space of one of its teeth.
The rotary motion of the ratchet-wheel B. on its shaft or arbor R causes the index-hand S to move over the face of the dial-plate S and register.
By the above means a perfect and accurate automatic register is formed.
Having thus described my invention, what I claim is- I 1. The shaft A and circular disk 0, having a portion of its periphery cut with cog-teeth and provided with pins (1 and 01 in combination with the circular disk B, provided with the pin 01 and pinion-wheel c, substantially as described.
2. A turnstile consisting of the shaft A and disks B and G, in combination with the magnets G and G, and connected therewith by means of a current of electricity passing through suitable circuit-closers, and actuating the armature H, pawls O, P, and T, lever L, ratchet-wheel B, and any suitable registering mechanism.
3. A turnstile consisting of shaft A and disks B and U, in combination with the magnets G and G, and connected therewith by means of a current of electricity passing through suitable circuit-closers, and actuating the armature H, pawls O, P, and T, lever L, ratchet-wheel R, index-hand S, and dialplate S, substantially as described.
4. A turnstile consisting of the shaft A and disks B and G, in combination with the electro-magnets G and G, and connected therewith by means of a current of electricity passing through circuit-closers D, D D and D and pin e on disk B, and button F, and actuating the armature H, lever L, pawls O, P, and 'I, ratchet-wheel R, and any suitable registering mechanism.
5. A tnrnstile'consisting of shaft A and disks B and C, in combination with the electromagnets G and G, and connected therewith by means of a current of electricity passing through circuit-closers D, D D, and D and pin 5 on disk B, and button F, and actuating the armature H, lever L, pawls O, P,
and T, ratchet-wheel R, and any suitable registering mechanism.
In testimony that I claim the foregoing l have hereunto set my hand this 29th day of March, 1877.
