the provision for the convenience of the spectators, the safety of the dogs, and, since doglo'racing has become a standardized sport, the construction of the race track must be such that it can be duplicated with exactitude in different locations. I In carrying out the first object of the in if) vention, the lure-operating means must be supported from the inner side of the track so that the spectatorsinay have an unobstructed view of the dogs, it must be of such restricted height that thepart of it in front of the grand- 2o standwill be below the line of vision of those in the grandstand, and thesupporting members or braces must be sodisposed and inclined as to ofier no obstruction t othe view of the race. Furthermore, the lure must be" 25 suspended by means of such attenuated con-. struction as to be substantially invisible.
In the interest of the safety of the dogs, the truck from which the lure is suspended must be retained upon the track on which it operates in such a manner as to prevent its derailment and falling in the path of the do s. 'f
1%Ioreover, means must be provided at the conclusion of the raceforstopping the dogs I without doing them injury.
From the standpoint of duplication of the race track, the trestle for supporting the tracks upon which the truck runs must be of such construction that they may be constructed in units, such as may be fabricated in toto at a mill or'factory and then transported to the place of construction and then set up. v
The present invention seeks the fulfillment of the above objects, andother objectsjsuch as may appear as thefollowing .description of a preferred and practical embodimentof the invention proceeds. I

I Referring now-in detail to the several figures, the numerailrepresents the race track which, as shown in Fig..II, is preferably oval in form and providedaround its inner peripherywith the railway 2 which carries the electrically operated truck 3. A lure 4 is suspended from; the truck, and depends into the path of the'dogs in advance of them. The" speed of. the truck is controlled from a switch box-5 and is always maintained at a rate slightlyfaster than the dogs can travel so asvv to induce them to put forth their best speed. r
As is shown inFig; II, where the general lay-out of a race course is diagrammatically represented, 6 designates-thejudges stand, 7 is a sunkenhydraulic lift or cage for bringing thedogs upon thetrack, and 8 the stopgate which functions inthe manner hereinbefore'described-to halt the dogs after they have passed thejudges stand at the conclusion of the race, in such a manner as tov avoid the possibility of injuring them.
. The numerals 9; 10; and 11 represent, re- 5 spectively, entrances for the dogs at quarter, half, and five-eighth track length intervals. l The railway upon. which the truck 3 operates is supported upon vertically disposed members such as are illustrated in Fig. I. Each of these comprises the vertical post 12 preferably of I-bearn cross-section and suitably braced in the rear or otf track direction by an inclined support 1 13b Atriangular bracket l bpreferably alsoof commercial. 95 structural steel construction, is secured to each post, overhanging the racecourse, said triangular brackets affording supportfor the stringers 15'and 16 which are laid cont-inuously around the racetrack, bridging the spaces between the supports. The supporting units are of such construction that they may be fabricated at a mill and transported intact to their final destination. The triangular supports are so inclined as to be out of the path of View of that part of the race course-which the dogs traverse and which the supporting brackets overhang;
7 Cross ties 17 are laid upon the stringers .15 and '16 and continuous sleepers 18 and 19 are placed upon said cross'ties,"saidsleeperscar upon suitably' geared to a driving axle '29 vcarrying the flanged drive-wheels 30, rests upon the rails 23 and 24and travels about switch box 5.
them when the motor is energized. ii
Theenergization of the motor is effectedthrough the third rail 25 by-electrical connections not shown. controlled from the .The lure 4 is rigidly suspended by-m'eans o'fza braced rod 31, the upper-end of which rod is.suit'ablylsecuredi to the truck 26.
Thus,- the lure travels with the truck in a continuous oval ipath,'preferably along the medianlline of the race course, apart of which is'constituted by a vacant ground space beneath the railway,-and the unobstructed visibility of which isgsecuredthrough novel construction of the supporting units.
.This visibility may be enhanced, particularly for nightracing bymeansgof electric lights, suitably disposed along-the inclined sides of the supportingbrackets 14.
The guard rails 21 and 22 extend continuously around the track and are constituted by members of angular section as shown, supported at proper intervals by brackets 20 fixed vertically to the sleepers 18 and 19. The guard rails overhang lthewheels 30, cooperating with the main rails 23 and '24; to form continuous angular spaces within which the tread portions of the wheels extend,so that thetruck is securely interlocked withrespect to the rails and cannot tip over or fall from the track into the path of the dogs, which has occasionally happened in devices of known structure, sometimes rworking injury to the dogs. v The'third rail 25 is carefully insulated from the supporting crossties and the motor is provided with a trolley 42 making continrent.
[The operation of theiinven'tion may be inferred from'thestructure whichhas been'described. The dogs may be started in *any suitable manner, thelure being carried before level of .the race track but being elevatable hydraulically, by means of the plunger 45 acting in a cylinder 46 and'being supplied .by fluld under pressure from any suitable across the race course, inhibiting the further progress ofthe dogs. The gate is'preferably formed with a rim of pipe-fittings 17 ,suitably" braced as indicated at 48 in Fig. IV; The gate is covered with-a canvas sheet .49,
and in the interest of the safety of the dogs the bottom member of the rim extends Very close to theground so as toinake it practically impossible for the runningdogs to come into. an ,engagement'with'it.
according to the principles of the present invention needs no outlet or switch upon which-to sidetrack the dogs at .the conclusion of arace, this further ensuring the safety of the dogs because they do not have toipi-le into the blind end of an offset portion of theztrack into which the linehaspreviously been run. l/Vhile-I haveinthe above description endeavoredf to define a preferred and practical embodiment of myinvention itis to be under stoodtliat thespecific details of construction as shownand describedare merely'by way of example, and not limitative with respect It is obvious that a race track constructed to the scope of the invention :as definedin the appended claims.
I claim 1. A. race track for dogs includingaplurality of vertical posts disposed along the inner right-of-way, right-angled triangular shaped brackets connected to the inner faces of said posts and projecting outwardly over the course, two traffic rails supported by said brackets, a guard rail mounted above in superposed relation witheach one of said trailicrails, a truck provided with rail-engaging wheels mounted upon the trafiic rails with the flanges out of contact but adjacent. to the guard. rails, wherebythe wheels are held against upward displacement, an electric motor .for driving the truck carried uous contact with the third rail 25', through which meansthe motorissupplied wit-h curthereby, a third rail supportedby said bracketsfor supplyingcu'rrent'to the electric motor,"a' right-angled arm having a short upper v rality of vertical posts inner right-of-way, two tra o rails supportsuspended from the lower free end thereof. 2. A race track for do s including a pluis osed along the ed by said posts, a guard rail mounted above in superposed relation with each one of said traflic rails,a truck provided with rail-engaging wheels mounted upon the traflic rails with the flanges out of contact but adjacent to the guard rails, whereby the wheels are held against upward displacement, an electric motor for driving the truck carried thereby, a third rail supported by said posts for sup plying current to the electric motor, a ,right angled arm having a short upper terminal connected to the truck with the longer terminal thereof projected beyond the inner ends of the brackets and terminating at a point slightly above the course, and a lure suspendedfrom the lower free endthereof.
