TU RNSTILE.

SPECIFICATION forming part of Letters Patent No. 562,293, dated June 16, 1896.

Original application filed March 18, 1895, Serial No. 542,237. Divided and this application filed J ly 31,1895. Serial No. 557,704. (No model.) Patented in Italy March 2,1895,N0.3S,3Z5; in France March 5, 1895, No. 2%,5'72, and in Belgium March 6.1895,No.114,4=08.

T0 at whom it may concern:

Be it known that I, ADRIAN GAJARZDO, engineer, a citizen of the Republic of Chile, residing at 16 Calle Prat, Valparaiso, Chile, have invented certain new and useful Improvements in Turnstiles, (for which I have obtained patents in France,No. 24t5,572,dated March 5, 1895-, in Belgium, No.1let,et08, dated March 6, 1805, and in Italy, No. 38,325, dated March 2, 1895,) of which the following, originally forming part of the application, Serial No. 54:2,237, filed on or about March 18, 1895, is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention relates to turnstiles and comprises the improvements hereinafter de scribed and illustrated in the accompanying drawings, wherein- Figure 1 is a plan of a double turnstile constructed according to my invention. Fig. 2 is a side elevation of the same, looking through the passage, a portion of the base being broken away to show the chain that connects the two shafts. Fig. 3 is an elevation of one of the turnstiles,'looking in the direction across the passage. Fig. at is a detail drawn to a larger scale and hereinafter described. Fig. 5 is a plan, and Fig. 6 is a side elevation, drawn to a larger scale,of the registering device applied to the turnstile. Fig. 7 is a section through the wheels of the registering device. Fig. 8 is a detail perspective view-of the longitudinally-movable bar and the actuatingdever for operating the registering-wheels.

A is the spindle or shaft of the turnstile, having a head made up of an upper set of three equally-spaced radial arms B and a similar lower set connected to the upper set by vertical rods B. There may be more than two sets of arms B forming the head, or there may be only one, but in all cases these arms are spaced at an angle of one hundred and twenty degrees. This construction allows the shafts A of the two turnstiles commanding one passage to be brought closer together than would be possible with four arms, while at the same time affording ample width of opening or passage at the front and back of the gate, as clearly shown in Fig. 1. On each shaft A near the foot thereof is fixed a cam A, having three angular-shaped projections that fit in corresponding recesses in a stationary cam A, secured to the bedplate of the turnstile. When the shafts A are turned in either direction from their position of rest, the cams A A operate to raise the turnstile bodily and then lower it again as the next arm blocks the passage. By this means the turnstiles are always brought to rest with their arms across the passage.

The registering device D is placed under the top plate C of the turnstile-frame. The registering-wheels (1 d Fig. 7, are operated by a pawl E, Fig. 5, carried by a bar F,which can slide to and fro in bearings F and which is operated by a lever G, pivoted at G. The said lever projects through a slot F Fig. 6, in the bar F, in which ithas a certain amount of free play, so that when it is turned in one direction it moves the bar F and operates the registering-wheels, but when it is turned in the other direction it moves in the slot F without affecting the bar F. The outer end of the lever G is controlled by the upper triangular-shaped end of the shaft A. (Shown clearly in Fig. 4.) IVhen the said shaft is rotated in one direction, each corner of the triangular-shaped end of the shaft successively turns the lever G and operates the bar F, and actuates the register; but when the said shaft A is rotated in the other direction the lever moves in the slot F and does not actuate the bar F.

fis a spring acting on the end of the bar F to push the said bar back to its initial position when the lever G is liberated by triangular-shaped end of the shaft A.

f is another light spring pressing on the lever G to prevent it from moving about loosely in the slot F The pawl E can be withdrawn from en gagement with the registering-wheels when it is required to throw the registering device out of action (as, for example, when an attendant is passing through the gate) by means of electromagnets K, which are arranged to control the pawl. The pawl E is a spring-pawl and is arranged in a slot F formed in the bar, as most clearly shown in Fig. 6, and is secured at one end to said bar, the free end of said pawl being normally held in engagement with said registering-wheels by the resiliency of the pawl. The pawl serves as an armature for the electromagnets K, and when the latter are engaged they attract the pawl and draw it within the slot 1* in the bar F and out of engagement with the registeringwheels. When the circuit is broken, the magnets release the pawl and the latter imin ediately springs back into engagement with the registeringwheels.

L denotes a battery which passes a current of electricity through the circuit containing the electromagnets K when the said circuit is complete.

M M denote comb-shaped metal bars included in the battery-circuit and placed in the foot-plate of the turnstile and so arranged that when the attendant whose boots are provided with metal plates steps thereon when passing through the turnstile he thereby coinpletes the battery-circuit and thus causes the pawl E to be disengaged from the registeringwheels.

There are two registering-wheels d (1 Fig. 7, one having say one hundred teeth and the other one hundred and one teeth. The wheel (Z is mounted loosely on the spindle d and the wheel (1 is mounted on the hub of the wheel (1 and both are controlled by the pawl E. The hub of the lower wheel carries a finger d that travels slowly relatively to the upper wheel by reason of the difference in the number of teeth in the two wheels and registers one hundred at each complete revolution, while a stationary point-er cFregisters from 1 to 100 on a graduated circle of the upper wheel.

I provide two registering devices, one on each turnstile. One of theseis arranged to be operated when the turnstile is turned in one direction and therefore registers admissions, say, and the other is operated when the turnstile is rotated in the other direction and therefore registers the persons passing out.

Both registering devices are constructed alike, it only being necessary to arrange the longitudinally-movable bars and their pawls that actuate the registering-wheels in reverse directions, as will be readily understood.

To keep the turnstiles in unison, they are geared together bya chain H, Fig. 2, that engages with a chain-wheel on the foot of one of the shafts Aand with another chain-wheel on a short counter-shaft carrying a wheel H, geared to the other shaft A.

\Vhat I claim is 1. In a turnstile, the combination with a vertical shaft carrying radial arms and formed with a portion triangular in cross-section, of toothed registering-wheels, a slotted longitudinally-movable bar, a spring-pawl carried by said bar and engaging said registeringwheels, a pivoted actuating-lever engaging at one end said triangular portion of the shaft and projecting through the slot in the movable bar at its other end, wherebysaid actuat ing-lever when oscillated operates to move the said bar in one direction only, and a spring for moving the bar in the opposite direction, substantially as described.

2. In a turnstile, the combination with a vertical shaft carrying radial arms and formed with a portion triangular in cross-section, of toothed registering-wheels, a slotted, longitudinally-movable bar, a spring-pawl carried by said bar and normally engaging said registering-wheels, a pivoted actuating-lever engaging at one end said triangular portion of the shaft and projecting through the slot in the movable bar at its other end whereby said actuating-lever when oscillated operates to move the said bar in one direction only, a spring for moving the bar in the opposite direction, and means for retracting the pawl from its engagement with the registeringwheels, substantially as described.

3. The combination with two turnstiles each comprising a vertical shaft having a portion triangular in cross-section and provided with heads carrying radial arms, of registering mechanisms for each shaft each consisting of toothed registering-wheels, a slotted longitudinally-movable bar, a spring-pawl carried by said bar and normally engaging said registering-wheels, a pivoted actuating-lever engaging at one end said triangular portion of the shaft and at its other end projecting through the slot in the movable bar whereby said actuating-lever when oscillated operates to move the said bar in one direction only, a spring for moving the bar in the opposite direction, the said longitudinally-movable bars and their pawls being reversely arranged whereby one turnstile operates to register the people passing through in one direction and the other to register the people passing through in the opposite direction, and means, substantially as described, for retracting the pawls from the registering-wheels, for permitting the passage of authorized persons without actuating the registering mechanisms, substantially as described.

In testimony whereof I have hereunto set my hand this 27th day of June, 1895.
