YADJUST'ABLE LOCOMOTIVE SEAT
Hampton Lilobby', Princeton, Ky,
Application May 28, 1937, 'Serial No. 145,372
(01. 155-88)
' 3 Claims.
This invention relates to locomotive seats.
At the present time, as far as American rail
roads are concerned, the requirement is that 10
comotive seats be securely‘ fastened to the ?oor
of the locomotive cab at all times. Locomotive
seats as now used and constructed are made of
wood and are fastened to the ?oor of the cab
in one position, without thought to the con
venience of the engineer. ‘
An object of the present invention is to pro
vide a locomotive. seat that maybe adjusted to
different positions and to different heights to suit
the convenience of the individual engineer op
erating the locomotive, and which seat, at the
same time, may be securely fastened to the ?oor
of the cab to meet. present railroad require
ments.

I
The invention, together with its objects and
advantages will be‘ best understood from a study
20 of the following description, taken in connection
in elevated position relative to the section I 0,
lugs I2 are engaged in the shorter notches I3.
To support the section I I in lowered and tele
scoped position relative to the section Ill, lugs I2
are engaged in the longer notches I4, as is ob
vious
»
The section II of the- seat supports the up
holstered seat I5proper, and the same is hinged
adjacent one edge thereof to one side of the sec
tion II through the medium of hinges I6 ar- ’
ranged within the con?nes of the section II and
wholly concealed when the seat I5 is at rest on
the upper edges of the section II.
Except for the side thereof in which the seat}
I5 is hinged,‘the remaining sides of the section" 16
II at the upper edges thereof are bent outward
wardly to provide narrow ?anges I'I upon which
the seat I5, proper, rests when in the position
shown in Figure 3.
Further, in accordance with the present in 20
with the accompanying drawings, wherein:
Figure l is a top plan view of the seat with
vention, the floor plate 5 has rising therefrom I
and adjacent one corner thereof an integral stud
the upper section of the seat removed.
Figure 2 is a perspective view of the upper
section of the seat.
Figure 3 is a vertical sectional view taken sub
stantially on the line 3-3 of Figure 2, but with
the upper section of the seat in an elevated po
bolt I8. To accommodate the bolt I8, the bot~
tom 9 of the seat section II] is provided with a
slot arrangement shown in Figure 2 and which 25
consists of a-pair of right angularly related in
terconnected slots I9, 20, and a diagonal slot 2I
that joins the slots I9, 20, at the angle between
the slots I9, 20, as clearly shown in Figure 2.
To secure the seat at the desired position of 30
adjustment relative to the floor plate 5, there is
threadedly engaged with the stud bolt I8, 9.
hand nut 22 adapted to be threaded home against
sition.
Figure 4 is a perspective view of a ?oor plate.
In accordance with the ‘present invention
there is provided a “dead” or stationary floor
plate 5 provided with openings 6 to accommo
date
screws or
other fastening elements
‘I,
35 through the medium of which the plate 5 is se
cured to the floor 8 of the locomotive cab.
Resting on the floor plate 5 is the bottom 9
of the lower box-like section I0 of the seat.
This section ID in addition to the bottom 9 has
40 side and end walls rising vertically from the
"bottom 9, and the section III is preferably formed
wholly of metal.
Further, the seat comprises an upper section
II which is of substantially rectangular frame
like form, constructed from sheet metal, and
adapted to be lowered and telescoped into the
lower section II] of the seat.
_
To support the section II in either raised or
lowered position with respect to the section I 0,
50 the latter is provided ‘on opposed walls thereof
with internal lugs I2 while the seat section II
in each‘of twoopposite sides thereof is provided
with short notches I3, and in each of two‘other
opposed sides thereof with longer notches I4.
As shown in Figure 3, to support the section II
a washer 23 disposed on the stud bolt I8 be
tween the bottom 9 of the seat section I 0 and 35
the nut 22.
.
Obviously, provision of the intercommunicat
ing slots I9 to 2| inclusive permits of a wide
range of adjustment for the seat, permitting the
latter to be moved laterally toward or away from 40
the side of the locomotive cab or either back
ward or forward to suit the convenience of the
engineer.
Manifestly, to' adjust the seat to the position
desired, the lever nut 22 is loosened and the seat 45
is then slid in the desired direction, being guided
to the position desired by means of the cooperat
ing bolt I8 and slot section in the bottom plate
of the seat structure. When the desired posi
tion is effected, the seat is securely fastened to 50
the cab by tightening the lever nut 22.
The height of the seat may be readily raised
or lowered simply by lifting out the section II,
giving it a quarter turn, and then placing it in
the section III of the seat.

It will thus be seen that I have provided a loco
2. In a locomotive cab seat, and in combina
motive cap seat which may, and is, in the pre
tion, a stationary floor plate having a bolt rising
ferred embodiment thereof, made of steel, and‘ vertically therefrom, a lower supporting section
which is adjustable to any desired position to suit having a bottom and vertical wallsv rising from
the convenience of the engineer operating the
locomotive. Also, a seat embodying the features
of the present invention will meet the require
ments of the railroad, provision being made, as
above noted, to securely fasten the seat to the
10 ?oor of the cab, as is necessary to meet the pres
ent railroad requirements.
It is thought that a clear understanding of the
construction, utility, and advantages of a seat
of this character will be had without a more de

ing slots to accommodate said bolt'and to permit
a shifting of the seat supporting section in sub
stantially any and all directions relative to said
