COMPLETE SPECIFICATION.
Improvements in Vehicle Seats.
I CHARLES F. DAVY, Farmer, of Starkville, in the County of Herkimer and
State of New York U.S.A. do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to certain improvements in vehicle seats, and has for its
object in part to provide a spring seat of a novel and inexpensive construction
adapted for use on vehicles of various kinds, as for example, agricultural machines,
locomotives and the like; the seat being adapted, when mounted on an agricultural
machine, to be used in connection with means whereby it may be adjusted in a
simple and convenient manner so as to stand at any angle to the surface over which
the machine is being driven. In this way the seat is made perfectly comfortable
at all times, and is caused to stand in a horizontal position even when the machine
whereon it is arranged is being driven over a side hill.
The invention consists principally in a seat supported on springs from a frame
adapted to be bolted to the seat posts of the vehicle, and having at its sides, studs
from which extend upwardly and oppositely inclined sole springs, so that the seat,
while capable of moving in all directions, is still held in position by said springs.
The invention also contemplates certain novel features of the construction,
combination and arrangement of the various parts of the seat, whereby certain
important advantages are attained, and the device is made simpler, cheaper, and
otherwise better adapted and more convenient for use than various other devices
heretofore employed, all as will be hereinafter fully set forth.
The novel features of the invention will be carefully defined in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure 1 is a side view showing an agricultural machine provided with a seat
constructed in accordance with my invention, and
Figure 2 is an end view of the seat support detached.
Figure 3 is a plan view of the same, and
Figure 4 is a vertical longitudinal section taken through the seat support
constructed according to my invention.
In the views, 1 indicates the vehicle to which the seat is applied, having a seat
standard 2 of the usual, or any kind, to which my improved seat may be attached
by means of a bolt 3 passing through a slot formed ou said standard and also
through a slot 5 in the lower section 4 of the tilting support, which is provided
at opposite ends with upturned brackets or lugs 6, to the upper parts of which are
pivoted or aligned bolts 7 the depending lugs or brackets 8 of the upper section 9
of said tilting support.
The upper section 9 of the tilting support is provided with a slot 10 engaged
by a bolt 11, also passing through a slot 12 in the lower section 13 of the spring
seat support or frame, which extends as shown in the drawings, longitudinally of
the vehicle, being provided at its front and rear ends with oppositely directed
arms 14, having hooks at their outer ends, to which are attached the upper ends
of coil springs 15 of suitable strength.
17 represents the upper section of the spring seat support or frame, which
extends transversely of the device, or substantially at right angles to the section 13,
and is provided with arms extending forward and back from its opposite ends

page_text: and provided with depending ends provided with books 16 to engage the lower
ends of the springs 15, as clearly seen in the drawings. The section 17 is slotted
at its central portion, as seen at 18 in the drawings, to receive a bolt 19 on the
seat 20, whereby said seat may be secured in place, and at its opposite ends said
section 17 is provided with projecting lugs or pins 21, the outer ends of which are
inclined upward and grooved, as seen at 23, to receive the looped ends of diagonal
side springs 22, the ends of which extend forward and back and downward and
are connected to the hooked arm 14 of the lower section 13 of the spring support or
frame.
The lower section 5 of the tilting frame is provided at its forward part with
two lugs 24, spaced apart to receive between them a lever or operating bandle 25,
having a pin 26 arranged to bear against the rear sides of said lugs or that side
nearest the forward bracket 8, and the said pin forms a pivot whereon said lever
swings, the rear end of the lever being formed into an eccentric arranged to engage
said Hange when said lever is operated, so as to lock the two sections of the tilting
frame together.
In operation, when the seat constructed according to my invention is attached to
an agricultural machine, as shown in the drawings, the seat may be adjusted
laterally to stand at any desired angle to the surface over which the machine is
being driven. For example, when the machine is being driven along a side hill,
so that were the seat fixed it would stand in an inclined position, and afford a very
uncomfortable and insecure support for the operator, the lever 25 is manipulated
to disengage the upper section of the tilting frame, after which the user allows
his weight to press on the higher side of the seat, causing said seat to again assume
a horizontal position, whereupon the handle or lever 25 is again operated to lock
the sections of the tilting frame together.
The device constructed as above described is exceedingly simple, durable and
inexpensive in its nature, and affords a very comfortable seat for all varieties of
vehicles, since the springs are so arranged that it may move against the tension of
the springs in all directions. Furthermore, the side springs 22 serve to prevent
rocking movement of the seat and hold the same moderately steady.
It will be obvious from the above description of my invention that the device is
susceptible of some modification, without material departure from the principles and
spirit of my invention, and for this reason I do not wish to be understood as
limiting myself to the exact form of the device herein set forth.
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. The combination of an upper frame section, a lower frame section, springs
secured at their upper ends to the lower section and at their lower ends to the upper
section and serving as supports for the upper section, and side springs extending
diagonally from the central portion of one section to the ends of the other section,
substantially as shown and described.
2. The combination of a lower frame section having oppositely diverging arms
at opposite ends, an upper frame section also having oppositely diverging arms at
opposite ends, said sections having their arms arranged at right angles to each
other, and the arms of the upper section being arranged to depend below the
arms of the lower section, springs uniting said arms of the respective sections,
and side springs, each connected at one end at or near the center of one section
and having its opposite end extending diagonally to one arm of the other section,
substantially as showu and described.
