JOHN SCHMIDT, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO JOSEPH S. SOI'IMITT, OF BROOKLYN, NEW YORK.

STARTERS GATE FOR RACE-TRACKS.

SPECIFICATION forming part of Letters Patent No. 575,130, dated January 12, 1897.

A li ati fil d June 19, 1896. Serial No. 596,165. (No model.)

of New York, have invented certain new and useful Improvements in Starters Gates for Race-Tracks; and I do declare the following and gates after revolution of the tube.

to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to-Which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to starters gates foiy racetracks, and has for its object the im provement of that class of devices which are employed to mechanically insure the fair and simultaneous departure of a number of racehorses side by side in a competitive trial of speed.

Each constituent element of my invention is described in detail, and its office, together with the mode ofoperation of the whole, fully explained hereinafter.

Referring to the accompanying drawings, wherein like numbers are used to designate like parts throughout the several views, Figure 1, presents a perspective View of the entire invention, showing the parts in their proper relations. Fig. 2 presents an end View showing one of two duplicate diamond-shaped frames, with the spring-return escapement mechanism and means for operating it. Fig. 3 presents an end View of the stall-bars and side view of the stall-gates, showing the rods borne by each gate near its lower edge arranged in contact with the uprights of neigh- V boring stall-bars. Fig. 4 presents aside View of the main cable, the revoluble tube in section, the cones and ball-bearings, and coupling joining the tube-divisions. Fig. 5 presents a side view of a stall-bar with its canvas partition and upright pivotalsupports, an end view of a stall-gate, and, in broken lines, the intermediate and final positions of stall bars Fig.

6 presents a side View of a whip, a portion of the whip-board being also'shown, with the lug constructed and arranged for attachment to the whip. Fig. 7 represents in perspective an end portion of the'whip bearing and controlling mechanism, showing the longitudinally-movable rod carrying pins provided for en gagementwith the whip-loops, the brackets having transverse sleeves supporting the rod, the fixed sleeves, the flat spring, and the latch, by which the rod is held against the force of the flat spring. For the sake of clearness all the remaining views are drawn upon a scale slightly larger than that adopted for the first figure. v

Considering Fig. 1, numeral 1 designates posts suitably held in upright positions, one upon each side ofthe track. The posts may be constructed in any chosen form, either of metal or wood, and each has an eye 2, through which may be passed the main cable 3, the ends of the cable being connected with fixed eyebolts or hooks 4 by the cable-tighteners or turnbuckles 5 5.

Considering Fig. 4, numerals 6 6 mark end cones encompassing and fixed upon the cable 3 at each side of the race-track near the posts 1. These cones form one-half of the raceway for balls 7 7 7, &c., to be again mentioned.

8 designates a compound cone, or it may be composed of two single cones having their bases in contact. The cable passes through the cone 8, the cone'being fixed in its position in some common and effective manner, as, for instance, by means of one or more setscrews. Gone 8 forms two lower halves of raceways for balls 9 9 9, &c The construction of the-cones and balls is that ordinarily adopted for ball-bearings, and no special description is believed to be needed. Number 10 designates the main revoluble tube. It is divided into one or more lengths in the case of a race-track of considerable width. For the purpose of this description but two tubelengths, one compound cone, and coupling only are represented. Obviously there could be provided more than one compound cone, the office of which is to furnish an intermediate support and bearing for the revoluble tube upon and between the ends of the cable. In almost every instance this construct-ion is demanded by the necessary length of cable and tube.

11 marks the coupling for the mid-track ends of the revoluble tube 10. Its construction may be varied, although a simple sleeve oppositely threaded interiorly at each end is usually most economical and convenient.

12 12, &c., are cups corresponding interiorly to cones 7 and 8 in form. They are fixed within the ends of the sections of tube 10 and form the other halves of the raceways for balls of middle and end bearings of the tube. The ends of each tube-section are exteriorly threaded, and diamond shaped frames 13 13 have cross-bars 14 14 provided with centrally-located interiorly-threaded orifices to receive and engage the outer threaded ends of the tube-sections. Brackets 14 14 are attached to the lower portions of the diamond-shaped frames, and at the outercorner of the brackets there are fixed padded projections 14 14", to be again referred to. The frames and immediate attachments are best shown in Fig. 2. At the upper point of each diamond frame a projection 15, having a pad 16, is situated, and at the lowerpoint of each of the frames 13 there is an unprotected projection 17 for the purpose of engaging the recessed cross-piece of the escapement mechanism described hereinafter.

18 designates a wire connecting the side angles f the frames 13 upon the side opposite b 'ackets 14, and the office of wire 18 is to support stall-bars and stall-gates after the revolution of tube 10.

19 19 19, &e., designate the stall-gates, sleeved pivotally upon the tube 10. Such is the construction of gates 19 that they maybe caused to swing forward, but not backward. Should any animal become too restless while between the stall-bars awaiting the startingsigual, the jockey permits the animal to pass out under the tube 10, the gate being swung easily upward out of the path. A rod19, projecting from gate 19, touching the near upright arms of two ad jaeent stall-bars, (see Fig. 3,) prevents the canvas band, which forms the gate proper, (see Fig. 1,) from be ing blown backward against the horses head or annoying the animal by swinging back and forth before his eyes. The attachments of stall-bars 20 20 20, &-c., are fixed to tube and move with it. To arms &c.,vertically depending from the tube-sleeves, the stall-bars are pivotally connected by pivotrods 21 21 21, &c., and a canvas partition 22, which also acts as a supporting connection, extends from each tube-sleeve to the stallbar proper, screw-eyes being set in each, to which the ends of the binding-cord of canvas 22 are tied. (See Fig. 5.)

23 23 mark overbalancing-weights attached by arms to theupper points of the frames 13.

24 24 designate the brackets attached to posts 1, supporting the boxes inclosing the spring return escapement mechanism, the boxes being marked 25 25.

2G 26, &e., designate (see Fig. 2) upright guide-posts rising from boxes 25 25, and 27 27 represent the reciprocative cross-pieces, having recesses or rectangular bends 28 28, eyes ieces 27 and 32 32 mark a cord tied to eve I P 29, by which each cross-piece 27 may be drawn dowmvardly against the force of spring 31. It is apparent that when the cord is released the springs will return the cross-pieces to their normal positions. Pulley-blocks 33 33 are suitably attached to boxes 25, through which the cords 32 32 may be led away to the starters stand. (See Fig. 1.)

34 34 designate posts set at each side of the race-track in proper relative situation and at a convenient distance from the posts 1 1. Upon the outside of each post 34 a grooved pulley 35 is revoluble upon a projecting pintle 36, and a short cable 37, running over pulley 35, connects with weight 38. (See Fi 7.) The remaining end of short cable 37 is connected with a whip-board 39, which extends entirely across the track parallel with the tube 10 and bears the whips and their operating devices.

40 designates a pin driven into post 34, to which rope 32 may be tied when it is desired to operate the invention from the vicinity of the whip-board post 34.

41 marks a flat spring attached to post 34, and 42 marks a pivoted arm or latch, also borne by that post. The offices of parts 41 42 are respectively to propel and to hold against propulsion a rod 43, having a bent end 44 and projecting pins 45 45, &c., to engage the whip-loops, to be described.

46 46 designate the brackets borne by whipboard 39 near each end. The brackets 46 have hollow cylinders 47, fixed transversely at their ends, and those cylinders fit movably about the rod 43, which may be actuated to and fro through them.

48 48 48, &c., designate the intermediate brackets borne by beam 39. Brackets 48 have sleeves 49, fixed transversely at their ends and bored to movably fit rod 43. Each sleeve 49 possesses a longitudinal recess 50, which corresponds in form and size with the recess in each of a number of sleeves 51 51 51, &c.,\vhich are fixed upon the rod 43.

52 marks the recesses of sleeves 51 51.

Along the upper edge of whip-board 39 are fixed lugs or curved pieces 53 53, designed to engage the whip-yokes 54 54 and to be attached thereto when set screws 55 55 are set up.

56 56 mark the spring-section of the whips, (see Fig. 6,) one end being joined to the yoke 54 and the remaining end to the whalebone or reed-and-lash port-ion 57 of the whip. Near the lash are the whip -loops 58 58, which engage pins 45 (see Fig. 7) when the whips are set.

Near the foot of post 34, Fig. 1, will be seen a grooved pulley 59, revoluble upon a pin 60, and about which cord 32 may be passed and lIO . the same strength as that applied to the backs cord 32.

tied to eye 61, which is provided near the end of latch 42. Pivoted to 62, which marks a portion of the starters stand, Fig. 1, is the bent lever 63, connected at the point 64 with If the cord has been drawn sufliciently taut, a movement of lever 63 will draw the cross-pieces 27 27 downwardly against springs 31 31 and at the same time the latch 42 will be withdrawn from before the bent end of rod 43, permitting the simultaneous rotation of tube 10 and the fall of the whips.

In the main view, Fig. 1, as the parts are shown to be assembled the projection 17 is represented as engaged with the recess 28 upon each side of the race-track. Assume that cord 32 is drawn upon and cross-pieces 27 27 depressed. \Veights 23 23, acted upon by gravity, turn the frames 13 13 and tube 10 into the intermediate position indicated by broken lines in Fig. 5. After being drawn upon the cord 32 is at once released and the cross-pieces 27 27 rise in time to intercept and engage the pads 16 16 of projections 15 15, arresting the revolution of the parts. The intermediate position of the frames and tube holds the stall-gates 19 above the line of horses andno obstacle is presented to their fair and prompt departure. It is necessary, however, to once more operate lever 63 or draw upon cord 32 in order that the frames, tube, stall-gates, and stall-bars should assume their final inverted and highest position, in which they are raised'entirely above the heads and out of the path of the horses and riders as they approach when completing each lap.

Considering Fig. 7, it will be understood that rod 43 may be moved to and fro within the sleeves of the brackets attached to the whip-board, and thatflthe correspondinglyrecessed sleeves 49 of brackets 48 and 51, fixed upon rod 43, coact when in contact to prevent the rotation of the rod. In drawing the rod 43 outwardly to bring the sleeves into engagement the force of flat spring 41 must be overcome, and to hold the rod in its outermost position the latch 42 must be turned up before the bend 44 of the rod. hen the action upon cord 32 removes the end of the latch, the reaction of spring 41 propels the rod inwardly, the sleeves 49 51 become disengaged, leaving the rod free to rotate, which it quickly does under the influence of the bent Whipsprings, the whip-loops 58 58 slip from pins 45 45, and each animal is struck precisely at the same moment, receiving a blow of exactly of any of the others in line with him. While rod 43 occupied its outward position, the grip upon it between spring 41 and latch 42 prevented it from rising, but immediately the rod is propelled inwardly and the whips sprung the whip-board and all its attachments rise more or less rapidly under the influence of diamond shaped frames 13 and tube 10 the wire 18 limits the descent (see Fig. 5) of the pivoted stall-gates, which would otherwise hang too low.

WVhile consisting of a number of parts, my invention as a whole is of such simple character that the manner of resetting the gate to start a subsequent race is believed to appear sufficiently plain from the description and drawings as already explained.
