Another object of the invention is the pro
vision of a box of this character,¿wherein the
doors for the separate animal compartments in
the .box are controllable through mechanism
which will assure absolute accuracy for the open

course, the ope-ning of these doors being uniform
throughout the series thereof and such mecha

ent invention comprises a comparatively light'
casing A including a bottom I9, ends II, front
I2, back I3 and top I4, respectively. Within this
casing A. are arranged suitable equidistanced ver
tical partitions I5 to provide a series of animal
stalls or compartments I6 which open through
the front and back of the casing. Into these
stalls or compartments are received the racing
animals. The o-pen back to each stall or com

A further object of the invention is the pro
vision of a box of this character which is com
e paratively simple in its construction, thoroughly
reliable and efñcient in its operation, the work
ing parts being exposed for free access thereto,
the opening of the doors of the boxes for start
ing animals in a race being effected uniformly
and with dispatch and the box in its entirety
being susceptible of manufacture at a minimum
With these and other objects in View, the in
vention consists in the features of construction,
combination and arrangement of parts as will
be hereinafter more fully described in detail,
illustrated in the accompanying drawings, which
disclose the preferred embodiment of the inven

In the accompanying drawings:
Figure 1 is a top plan view of a starting box
constructed in accordance with the invention,
a portion thereof being broken away at its top
for illustrating interior organization.

tion of the arrows.
Figure 3 is an enlarged fragmentary detail
ing of the casing A in any desirable manner. At
these open backs of the compartments o-r stalls
I6 the racing animalsy are admitted into, the
`casing or starting box.
Arranged for horizontal swinging movement
at the open fro-nts to the stalls or compartments
I6 are double starting doors I8 which upon open
ing allow the freedom of the racing animals for
racing purposes. It is preferable that these doors 35
be swingingly supported upon hinges I9. When
the doors I8 are in closed position this is a bar
rier for the freeing of the racing dogs within the
starting box.
Arranged upon the top I4 of the casing A
transversely thereof at its center is a guide rail
20, while at proper `distances removed inwardly
from the ends Il of the casing A parallel with
said rail 2D are bearings 2| upon which is mov
ably supported the coupling rail 22 of a door 45
opening plunger frame 23 having the diagonally
disposed braces 24 joined with said rail 22 to
effect a rigid structure. The plunger frame at
the center bar thereof carries on opposie sides
substantially L-shaped angle members 25, these 50
being overlapped with respect to the guide rail

Adjustably mounted in the rail 22 are eye bolts
