ADRIAN GAJARDQ OF VALPARAISO, CHILI.

GATE FOR USE IN CONNECTION WITH PASSENGER-REGISTERS.

SPECIFICATION forming part of Letters Patent No. 460,719, dated October 6, 1891. Application filed March 2, 1891. Serial No. 383,438. (NomodeL) To all whom it may concern.-

Be it known that I, ADRIAN GAJARDO, engineer,a citizen of the Republic of Chili, and a resident of Valparaiso, in the Province of Valparaiso, Chili, have invented certain new and useful Improvements in Gates for Use in Connection with Passenger-Registers, of which the following is a specification,reference being had to the accompanying drawlugs,

My invention relates to apparatus for registering the numberof persons entering or leaving tramway-cars and other vehicles, buildings, and other places, and comprises certain improvements in the apparatus of this kind or class described in the specification of my Letters Patent of the United States, granted to me October 7, 1890, and numbered 437,985. In the said specification I have described an apparatus wherein a pair of side posts or pillars are each supplied with two arms, bars, or gates secured at right angles to one another upon a vertical shaft or spindle, one of these arms or gatesviz., that through which the persons pass and hereinafter designated the primary arm or gate-projecting inits normal position directly across the path or passage, While the other or auxiliary arm rests at the side thereof, so that when a person presses back the first-named bar in passing the same the vertical pillar or shaft-is thereby rotated'and the auxiliary arm is moved round over the path to prevent another person passing till the arms have again resumed their; normal position, which they do automatically under the influence of suitable springs. Now in some situationsas, for instance, in tram-cars and other vehiclesthe amount of space which is available is frequently too small to permit of the use of these primary and auxiliary arms, as hereinbefore described,'and my present invention is chiefly designed to overcome this difi'iculty by constructing the said primary and auxiliary arms in a more compact form than that described in the said former specification.

An important feature of my present invention consists in making the auxiliary arms or gates which serve to prevent the entrance of more than one person at a time in the form or approximately in the form of a segment of a circle, and so arranging the same that when the parts are in their'normal position the said segmental auxiliary arms are retired into suitably-shaped recesses or guides behind the pivots of the primary arms, the two sets of arms being coupled together and co-operating, as hereinafter described, so that when the primary arms are pushed backward or displaced the auxiliary arms are moved out of their respective casings or recesses and serve to prevent any one passing the apparatus un-' ratus shown in Fig. 1, a part of the casing being removed to show the operating mechanism, and Fig. 4 is a similar View of the apparatus shown in Fig. 2. Fig. 5 is a side view of the apparatus, one of the arms and a part of the casing being removed, showing the operating device in position. Figs. 6 and 7 are views, hereinafter referred to, showing certain de tails of the mechanism.

A A are the twouprights or fixed side portions of the apparatus.

B and 0 represent the respective co-operating arms of the apparatus, B being the primary arms between which the person enters,

and 0 being the auxiliary arms, the purpose of which is to prevent more than one person passing the apparatus at a time. .Theseauxiliary arms are adapted to enter suitable recesses 0, provided to receive the same in each 7 'of the side posts or uprights, the said recesses being open at both ends to permit of the auxiliary arms sliding out of the same from either end thereof.

D is a vertical shaft or spindle, upon which the arms B are carried, and which is provided atits lower extremity with a collar or enlargement E, in the circumference of which a camgroove E is formed. This cam-groove is adapted to act on a suitable pin or stud F,"

carried at the extremity of a curved piece G,

forming one arm of a bell-crank G, secured upon a pivot II at the base of the upright. The other arm of this bell-crank is connected by a flexible steel or other suitable rod or bar I, which also serves, as hereinafter described, the purpose of a retracting-spring with the auxiliary arm 0. The rod or bar I is connected with the auxiliary arm by a suitable universal joint, preferably comprising a ball J, carried in arms or brackets K, secured to the said auxiliary arm.

The whole apparatus is preferably fitted up in duplicate-that is to say, each of the uprights A is provided with one or more primary arms or gates B and with one or more auxiliary arms 0, connected and cooperating together, as described.

The construction of the bell-crank G and the flexible rodIis shown more clearly in Figs. 6 and '7, the former of which is aview of the said parts in side elevation, while the latter is a plan thereof. It will be seen that the curved arm C of the bell-crank is bent for convenience, so as to partly surround the collar or enlargement E on the shaft D.

As above mentioned, the flexible rod or bar I is connected to the segmental auxiliary arm by means of a perforated ball J, through which passes a projection or stem I on the red I. The ball J fits into two suitable re cesses or sockets, formed one on each of the adjacent extremities of thebrackets K,which partially inclose the same and retain it in position, as shown more clearly in Fig. 5, while permitting the free motion thereof about its center to allow it to correspond to the changes in the relative position of the short stem 1.

The operation of the apparatus is as follows: On a person passing into the car, vehicle, building, or the like, at the entrance of which the said apparatus is situated, the primary arms are moved in the direction indicated by the arrows in Fig. 1, thereby operating the counting mechanism situated at A, (which counting mechanism is substantially similar to that described in the said former specification No. 15,898,) and at the same time causing the vertical shafts or spindles D to turn on their axes. The cam groove formed in the collar or enlargement E of each of the said spindles I) thus caused to act on the pin F of the bell crank G,which is turned upon itspivot H, and causes the flexible rod or bar I to move in a correspondingdirection, and to draw the auxiliary arm 0 out of the recess in which it is situated, and to move the same forward to close the path between the uprights of the apparatus. Since, however, the said auxiliary arm moves in a curved or circular path, the flexible rod or bar I, which is rigidly secured to the bell-crank G, is bent or twist-ed to one side in the act of withdrawing the auxiliary arm, and energy is thereby stored in the same to cause it to act as a retracting-spring to effect the return of the parts to their normal position aft-er the person has passed through and is clear of the arms B. This return force to rotate the shaft or spindle D upon its axis, and so swing the arms 13 back to their normal position and close the path.

In cases where it is desired to register the number of persons passing the apparatus in the opposite direction to that hereinbcfore described the arms B and O co-operate together in a similar manner to that above set forth, since the said arms 0 can, as hereinbefore mentioned, be moved out of either ex-- tremity of the recesses adapted to receive them. The action of the mechanism in this instance will be more clearly understood by reference to Fig. 3, from which it is evident i that if the arms B are moved in the opposite direction to that indicated in Fig.1 the camgroove IE will act to raise the arm 0' of the 1 bell-crank G, instead of to lower it, as in the former case. The etfect of this will be to throw the flexible bar I backward and to move the. auxiliary arms out behind the person passing through the apparatus, the said flexible bar being bent to one side or put in a state of tension in following the motion of the said auxiliary arm, as hereinbcfore described, and serving by its reaction to restore the arms to their normal position.

It is obvious, however, that instead of a separate cam and bell-crank being provided in each post A only one of the posts A might be so fitted, the two sets of arms on either side of the entrance being coupled together by suitable connecting gearing arranged beneath the flooring or foot-plate, the motions of one set thus serving to operate both sets of arms or gates. Moreover, instead of the cylinder F. having the cam-groove E formed therein, any other suitable form of cam may be employed in place thereof.

It is obvious, moreover, that other parts of my said invention-as, for instance, the joint by which the flexible bar I is connected to the auxiliary arm Cmay be modified without departing from the nature thereof.

lVhat I claim is 1. In a gate for use in connection with passenger-registers, the combination, with one or more gates, of one or more curved or segmental arms and a flexible rod orrods indirectly connecting said gates and arms for operating the parts, in the manner and for the purpose substantially as described.

2. In a gate for use in connection with passenger-registers, the combination, with a gate or gates secured to rotating shafts, of one or more curved or segmental arms and a flexible ITO rod connecting said gates and arms for operating the parts, substantially as described.

3. In a gate for use in connection with passenger-registers, the combination, with the shaft D and gates 13, of the arms 0, and flexible rods I, attached at one end to said arms arms 0, and flexible rods I, the latter being connected with said arms bya universal joint and with said collar by a bell-crank, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing by means of a universal joint and at the other witnesses. end with the said shaft by means of a bell- ADRIAN GAJARDO. crank, substantially as set forth. Witnesses:
