WILLIAM HERRMAN BRENNER, OF YOKOHAMA, JAPAN.

STARTING-GATE FOR SPORTS.

T 0 all whom it may concern:

Be it known that I, IVILLIAM HERRMAN BRENNER, a citizen of the United States of America, residing at No. 1 Isogo, Biyobugaura, Kuraki-Gori, Kanagawa Ken, Yokohama, in the Empire of Japan, have invented certain new and useful Improvements in Starting- Gates for Sports, of which the following is a specification.

This invention relates to apparatus for use in connection with sports, such as races, and comprises an improved starting gate adapted for being worked by one operator; the object being to provide apparatus whereby the gate may be set in the desired position so as to obstruct the passage of the racers and moved out of such position without giving any preliminary indication to the individuals concerned in the actual race.

The improved gate is particularly adapted for horse racing the horses being lined up for the race at a convenient distance from the starting point, and started simultaneously at a time determined upon by the starting official. The gate is raised without giving any intimation to the riders and thus the riders nearest the starter cannot gain time over those situated remote from the starter; moreover the gate cannot be interfered with by anyone except the oflicial starter thus obviating accidents to riders and horses.

In order that the said invention may be clearly understood and readily carried into effect I will proceed to describe the same with reference to the accompanying drawings in which:

Figure 1 is a front view showing the gate in the starting position, Fig. 2 is a front elevation of the upright of the gate situated near the starter, showing the barrier in position for obstructing the course, Fig. 3 is a front elevation of the upright situated remote from the starter or at the opposite side of the course, the barrier being raised, Fig. 3 is a partial side view of this upright, Fig. l is a detail view of the operating and releasing mechanism, Fig. 5 is a vertical section on the line 5-5 of Fig. 4:, Fig. 6 is a plan view of Figs. 4c and 5, with the worm and worm sector removed, and Figs. 7 and 7 are detail views of the buffer on the gate.

A and B are two uprights placed on each side of the race course. To these uprights are pivoted compound arms C which carry a barrier 0 of tape or any other suitable ma- Specification of Letters Patent.

terial adapted to extend across the course between the arms. When the arms C are down the gate is set ready for the horses to line up; the raising of the arms has the effect of rendering the course clear and of indicating or signaling for the riders to start the race.

A is the upright nearest the starter, B is the upright 011 the opposite side of the course; C are the compound arms on the uprights A and B.

D and E are wheels or sheaves mounted on a common shaft on the uprights and adapted the one E to rotate on the shaft and the other D to remain stationary on the said shaft, the former actuating the arms C as a whole and the latter the outer member C of the said arms.

F and F are wheels fixed to the outer members 0 of the arms C.

G is a wheel or disk which is mounted on the upright A and provided with a wormwheel sector G in gear with a worm H car ried by the shaft H, a detachable actuating handle it being provided for use in rotating the worm H. I is a bracket and guide for supporting the said worm and shaft and J is a lever for raising and lowering the worm H into and out of mesh with the worm wheel sector G. The bracket I (Figs. 4: to 6) is secured to a member I carried on the upright A of the gate and is provided with a slide I which is capable of vertical movement relatively to said bracket. This slide I is provided with two slots I I engaging with two pins I I carried by the bracket I and which serve to guide the slide in its ver tical movements. Movement is imparted to the slide I by the pin J of the crank J which is mounted on the shaft J 3 carried by the bracket I and actuated by the lever J. The shaft J is provided with a spring J which tends normally to keep the lever J in its lowered position so as to disengage the worm H from the worm wheel G. In order to engage the worm H with the worm wheel Gr it is necessary to raise the lever J into the position shown in Fig. 4 against the action of the spring J, and the lever J is retained in this position by the trigger K which is brought into engagement with a pin J on said lever.

L, L are counterweights carried by the compound arms, and M are springs co-aeting with and assisting said counterweights in their action.

N are butters each comprising a plunger N which is arranged between the two springs N N the upper extremity N 01 the plunger being forked to receive the arm 0 when it has been raised to a predetermined point.

O are guide wheels, P P are wire ropes and Q are members securely attached to the uprights and let into the foundation to prevent said uprights from turning. The wire ropes P, I are secured to the sheaves E and the wheel G in any suitable manner, but are so arranged that the ropes are wound around the sheaves when the gate is in its raised position; a pull 011 the rope owing to the operation of the wheel G thus serving to impart the rotary motion to the sheaves E to lower the gate and obstruct the course.

To set or lower the gate, the handle h is placed 011 the shaft H, the lever J is raised to throw the worm H int-o mesh with the Worm wheel G, and the trigger K is moved into locking position. The handle is then turned and communicates its motion to the worm H and worm wheel sector G. The wheel G carrying the worm wheel sector is mechanically connected to the wheel E and communicates motion to it; this wheel being secured to the arm C and rotatably mounted on the upright A thus depresses the arm G against the action of the spring A. The wheel D being secured to the upright and mechanically connected with the Wheel F by means of the rope 7, causes the said wheel to revolve and so eiiect the depression of the outer member C of the arm C. Owing to the wheel D being of larger diameter than the wheel F an increased rotary motion is imparted to the said wheel F and to the member C of the compound arm to which it is secured with the result that it is rapidly depressed and assumes the position shown in Fig. 2. The wire rope P attached to the wheel G is led over the guide pulleys O on the upright A, thence overhead to the guide pulley O on the opposite upright B, and attached to the wheel E on this upright. Any motion imparted to the wheel E on the upright A is therefore simultaneously imparted to the wheel E on the upright B. The gate when set assumes the position shown in broken lines in Fig. 1.

To raise the gate, the trigger K withdrawn in any suitable or convenient manner as for example by hand or by a'mechanical or electrical device; the bracket I and worm H are then free to fall out of mesh with the worm wheel sector G, said worm and sector being assisted in their disengagement by the spring J The counter weights L and springs M may then rapidly raise the arms C and U and impart an accele 'ated motion thereto. The outer arms 0 are connected to the arms C so that their relative rates of angular movement are proportional, the arms C moving faster in the ratio of the diameters of the actuating pulleys. The tapes constituting the barrier being attached to the outer members, rise rapidly and thus remove the temporary barrier from the course. The handle it can then be removed from the worm shaft II so as to render it impossible to lower or reset the gate. The gate when raised assumes the position shown in full lines in Fig. 1.

hat I claim and desire to secure by Letters Patent of the United States is 1. In a starting gate, the combination of uprights, con'lpound arms on said uprights, comprising inner and outer members, a barrier carried by the outer members of said compound arms and adapted to be placed across or removed from the course, and means for imparting a greater angular velocity to the outer members than the inner members of said compound arms during the raising and lowering of the barrier.
