COMPLETE SPECIFICATION.
Improvements in Safety-cars.
I, JEFFERSON ALEXANDER BEAUMONT, of Woodville, in the County of
Wilkinson and State of Mississippi, United States of America, Clerk, do hereby
declare the nature of my invention for IMPROVEMENTS IN SAFETY-CARS, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
My invention relates to an improvement in safety-cars; and it consists in the
construction and arrangement of parts hereinafter described and claimed.
The object of my invention is to provide a detachable section for a car which
may be detached from the interior of the car in case of accidents to form an
egress-opening for the passengers. I attain this object by the construction
illustrated in the accompanying drawings, wherein like letters of reference indicate
corresponding parts in the several views, and wherein―
Fig. 1 represents a section of a car with my improvement.
Fig. 2 is a detail inside view of a detachable section, showing the casing partly
broken away.
Fig. 3 is a detail perspective of a modified form of bolt-actuating means.
In the drawings, A represents a car having rectangular openings B in its sides
with beveled edges, as shown in dotted lines. This opening is formed to occupy
about the space of two windows, and extends nearly the height of the side. In
the top and side walls of this opening are formed suitable bolt-holes, while in the
bottom wall or sill is formed two inclined rectangular openings.
C is the removable section having beveled or chamfered edges adapted to closely
fit the walls of the opening the inclination of which permits of only an outward
movement of the section. Two tongues D are secured at an incline to the lower
part of the section and adapted to fit in the rectangular openings in the sill of the
section-opening. In the upper portion of the section are formed suitable bolt-
holes through which the outwardly-extending bolts E E E pass. These bolts
are arranged in suitable guides and have their inner ends pivotally secured to a
rocking lever F, pivoted to the section. One end of this lever has a crank G thereon,
(shown in dotted lines) the movement of which forces the bolts simultaneously out or
draws them in, as the case may be. In Fig. 3 I have shown the crank integral
with the centre of the lever. By the above construction it will be seen that
should a car be thrown on its side the sections, which I intend placing two or more
on both sides of the car, may be readily detached by turning the crank, forcing
the bolts in to unlock the section, and permitting it to be forced up or off, the
inclination of the lower tongues preventing them from binding and allowing the
section to be easily forced out.
I am aware that many minor changes in the construction and arrangement of the
parts of my attachment can be made and substituted for those herein shown
and described without in the least departing from the nature and principle of my
invention.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a safety-car, a movable section having inclined edges, a series of movable
bolts actuated by a crank in the upper part of the section, and tongues in the
lower part, substantially as described.
2. In a safety-car having a series of openings therein formed with outwardly-
inclined walls, removable sections fitted in said openings formed with inclined
edges, and sliding bolts for retaining the sections in place and releasing them
when drawn back, and a crank for operating said bolts simultaneously, substantially
as described.
Dated this 20th day of December 1890.
