LOUIS LEFLEVE, OF HOUSTON, TEXAS.
CATTLE-GUARD.
SPECIFICATION forming part of Letters Patent No. 513,946, dated January 30,1894.
Application filed July 20,1893. Serial No. 481,071. (No model.)To all whom it macy concern:
Be it known that I, Louis LEFLEVE, a citi-
zen of the Republic of France, formerly of
St. Laurent, Department of Ain, France, now
5 a resident of Houston, county of Harris, State
of Texas, have invented certain new and use-
ful Improvements in Cattle-Guards for the
Use of Railroads and other Public Crossings;
and I do hereby declare that the following is
to a full, clear, and exact description of the in-
vention, which will enable others skilled in
the art to which it appertains to use the same.
The object of my invention is to provide a
simple and inexpensive form of cattle guard
15 comprising rollers, wherein any roller may
be removed and replaced readily and also
the different bars composing each roller may
likewise be removed.
My invention includes the details of con-
zo struction and arrangement hereinafter point-
- ed out.
In the drawings, Figure 1, is a plan view of
the guard complete between the rails; Fig. 2,
a longitudinal section, and Fig. 3, a perspec-
25 tive view of one of the removable rollers.
Fig. 4 is a view of a detail.
The guard comprises a frame made up of
side bars 1 with inclined ends between which
extend the cross end plates 2 inclined to cor-
3c respond with the inclined ends. The side
bars have bearing openings through which
pass the bearing rods 3. Removably on these
the rollers 4 turn and any one of these rollers
may be removed by taking out the bearing
35 rod. These rollers are of novel construction
and consist of fourbars radiating from a cen-
tral point but having their inner edges at aslight distance apart to leave an open center,
and through this open center the bearing rod
is free to pass. The bars are connected with 40
the head plates 5 by means of tongues 6
clinched to said head plates, and thus any
bar may be removed from any roller as de-
sired. These head plates besides connecting
the bars of each roller serve also as bearing 45
plates for the bearing rods which pass re-
movably through them.
The action of the invention will be well
understood, the toothed edges of the bars
serving to pinch the animal's foot when any 50
roller is turned by its treading thereon and
causing the animal to back off of the guard.
The rollers are of such size and are so placed
in relation to each other that the animal's
foot cannot fall down between them and be 55
permanently caught.
I claim-
1. A cattle guard comprising the frame; the
rollers having a series of bars held with a
space between their inner edges, and the re- 60
movable bearing rod, passing through the
sides of the frame and through the open space
of the rollers, substantially as described.
2. In combination, in a cattle guard the
frame, the rollers made up of a series of bars 65
arranged with a space between their inner
edges, the head plates connecting the bars
and the bearing rods passing through the
head plates and into the space between the
bars, substantially as described.
