1. LOUIS STERNE of 2 Victoria Mansions Westminster in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a method of fixing rails chair to metallic sleepers, the
object which I have in view being to avoid the use of pieces, such as bolts, clip's
rivets and the like separate from the chair and sleeper themselves. For this purpose,
I make the underside of the chair with a T headed stud projecting from it, this stud
being cast into the chair or otherwise securely fixed to it. Through the upper metal
of the sleeper I cut a slotted hole such as will let the T head of the stud pass through
it, and I make the length of this slot lie in such a direction that the chair having been
placed on the sleeper with the stud passed through the slot, has to be turned about
one quarter round to the attitude in which it receives the rail. By this partial turn
the head of the stud is engaged under the lips of the slot, so that the chair is held
down by it. In order to allow for slight inaccuracies of fit and to give a steady fixing
for the chair, I provide in the lower face of the chair inclined hollows into which,
when the chair is turned, engage spring pieces projecting a little up from the face of
the sleeper-When the sleeper is of wrought iron or steel, these spring pieces may be
tongues punched up from it. When the sleeper is of cast metal, the springs may be
bent pieces of steel plate laid into hollows formed in the face of the sleeper.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 of the accompanying Drawings is a side elevation of a metal sleeper
showing the chair in end elevation. On the underside of the chair A a T headed
or other shaped stud a projects from it and which is passed through the slotted
hole in the sleeper B. The stud a can either be cast with the chair or otherwise
securely attached to it. By partially turning the chair A the stud a engages with the
lips of the slot b. In order to give a steady fixing for the chair A I provide in the
lower face of the chair inclined hollows c, c into which when the chair
turned engage
spring pieces d, d projecting a little up from the face of the sleeper B. When the
sleeper is of wrought iron or steel these spring pieces may be tongued and punched
up from it. When the sleeper B is of cast metal the spring pieces d, d may be bent
pieces of steel plate laid in the hollows formed in the face of the sleeper.
Fig. 2 is a plan of Fig. 1. The same letters of reference represent the same parts
as in Fig. 1.
Fig. 3 is a side elevation of the chair showing the hollows c, c and springs d, d in
section.
Fig. 4 is an end elevation of the chair and Fig. 5 a plan of the same.

page_text: Fig. 7 represents in end elevation the chair but instead of the inclined hollows c, c
Fig. 1 I strike up two tongues ff which act as stops.

Fig. 11 plan of Fig. 10 and Fig. 12 plan of the sleeper B.
I wish it to be understood that the tongues f f Figs. 7 to 12, act only as stops and
take up side thrusts and do not in any way act as springs or clips.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is
A chair provided with a headed stud projecting from the under side of the chair and
by a partial turn engages with the sleeper and securely fixes the chair to the sleeper
as herein before described and illustrated.
