,DOG RACE TRACK.

Application llecl June 1,

rl`his invention relates to dog racing devices, and particularly to certain improvements upon the dog racing device shown in our pending application for patent, Serial. No. 171,304, filed on the 26th day of February, 1927.

One of the objects of the present invention is to provide means whereby the rabbit at any desired part of the course may be caused to leap into the air as if jumping a hurdle. I

A further object is to provide' a spring suspension for the motor of the rabbit carriage.

A still furtherobject is to provide wheels disposed to bear against each side of the track so as to prevent any lateral movement of the carriage.

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a transverse section of a dog race track showing one of the supporting posts in elevation;

Figure 2 is a side elevation of a portion' of the track and carriage operating thereon;

Figure 3 is a vertical sectional view showing the carriage in elevation or looking toward one end thereof.

Referring to these drawings, 10 designates a wooden track which, of course, has any desired extent and may be a straightaway track or a curved track, as desired. This track is supported by means of thc I-beam 11 which is bolted to the bracket l2 which projects outward from any suitable pole or support or any other overhead structure. XVe do not wish to be limited to the particular construction of the track. lVe have shown the I-beam as being formed ot two channel irons to permit the passage of electric wires but, of course, are not limited to this. The track 10 carries upon its upper face the wear plates 13.

The carriage upon which the rabbit is supported includes the motor supporting frame 14. The forward end of this frame has a forwardly projecting lug 15 and a two-armed yoke 16` is pivotally engaged with this lug 15, the two arms 16 extending upward and inward around the track l() and carrying upon their extremities the wheels 17 which bear upon the wear plates 13. The rear end of the motor supporting frame 14 is also formed with a rearwardly `pro- 1927. serial No. 195,779.

jecting lug or lugs '18 having the yoke arms 19 operatively engaged therewith, which extends upward and then inward over the track and carry the wheels 2() which also rest upon the wear plates 13. The lower end of the yoke 19 is formed with a downwardly depending pin 2l which extends through an aperture in the lug 18 and the lug 18 rests upon a coiled compression spring 22 which surrounds the rod 21 and at its lower end bears against a nut 23 carried by this rod. Thus one end of the motor frame is spring-supported, thusac- -commodating irregularities in the track.

Mounted upon the motor shaft 24 are the relatively large dished wheels 25 car'rying preferably the rubber tires 26 which bear against the under face of the track 10, these wheels constituting means whereby the carriagemay be driven. The spring 22, it will be seen, urges these wheels upward against the under face of the track soas to secure a good tractive engagement therewith. Also mounted upon the frame of the motor or upon the yokes 16 are arms 27 which carry upon them the rubber-tired wheels 28 which bear against the opposite faces of the vertical web of the I-beam 11. These arms 27 may be mounted in any suitable manneras, for instance, in the manner illustrated in our prior application, but it will be noted that in the prior application these arms carried rollers of relatively small diameter, whereas the wheels 28 are of relatively large diameter. These wheels 28 prevent the motor and its supporting frame or yoke from any tendency to twist upon the track and cause the carriage to take. all the curves of the track. j

The rabbit 29 is mounted 0n the end of a depending arm 30. The upper end of this arm is carried upon a transverse rock shaft 31 mounted in suitable bearings, in the yoke arms 16, the arm supporting the rabbit extending downward and forward, though it will be understood that the rabbit-supporting arm might trail behind the carriage, assuming that the carriage is moving in a reverse direction to that illustrated 1n Figure 2. The shaft 3l carries an upwardly and rearwardly projecting arm 32 having a roller 33 or lwheel at its upper end. At intervals along the track or at any desired place iro.

:tace of the track 10, but when the roller reaches this protuberanee, the rear end of thearm 32 will be depressed and the rabbit will have lifted so that the rabbit can under these circumstances pass over a hurdle or other obstruction on the track, thus causing the do s to jump the hurdle when they reach it. T ere may be as many of these protuberances 34C as desired.

For the purpose of lighting the track, we have provided the upwardly extending tubular post 35 embedded at its lower end in concrete and having the brace 36 which extends upward to the lateral arm 37 of the post. This. post is hollow, as is the arm. llhe ll-beam 11 is attached to the extremity of the arm by bolts or other suitable means and the wires 38 which lead :from any suitable source of energy pass through these hollow posts 35 and are then carried to the metallic plates 14 which engage the metallic trolley wheels 17. From thence the current passes by wire to the motor in the manner illustrated in our prior application. We do not wish to be limited to any particular means for conducting the electric current to the motor, as this may be accomplished in any obvious manner. 'llhe current might be taken, for instance, from the wheels 28 or from the wheels 17 or the wheels 20, as desired. Electriclights 39 may also be mounted upon the braces 36 and connected to a source of current so as-to illuminate the track.

While we donot wish to be limited to this, preferably the post 35 will be formed in two sections, a short section which is inserted in a concrete base and a longer upper section, these sections to be connected b'y a screw-threaded coupling 40' so that if it be desired to shift the track from one place to another, the upper sections of the post 35 may be removed from the lower sections without the necessity of tearing up the concrete bases or constructing new posts.

1. A dog racing apparatus including an overhead track, a carriage operating on the track, a motor mounted on the carriage, means for conducting electricity to` the motor, a lure support pivotally mounted upon the carriage and normally extending downward therefrom, the lure support having an arm, and a roller engaging the under face of the track, the under face of the track being provided at intervals with protuberant portions acting to depress the roller and elevate the lure-supporting arm.
