Improvements relating to Railway Sleepers.
I, JOHN RANDOLPH GREEN, of Woodstock, Bibb County, Alabama, U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide means whereby a continuous bearing
for the rails is provided, in combination with simple means for keeping the sleepers
equi-distant.
By this invention the sleepers consist of suitable lengths of metal preferably
hollow, of square section, and having suitable flanges on their lower edges. The
ends of these sleepers are formed in such manner as to adapt them to be mortised
into the opposite sides of a metal block which is inserted between the ends of the
sleepers at suitable intervals; the rail passing over it. A groove extends at right
angles to the rail, in the block, and in the bottom of the groove is an aperture
through the block, adapted to engage the end of a tie-rod which extends between
two similar and oppositely-arranged blocks on the track. The ends of the tie-rod,
which enter the apertures of the blocks, are bent at right angles for that purpose.
The upper edges of the slot are dovetailed to engage the bevelled edges of a key
which is driven therein over the tie-rod, to keep it in place. The end of the key
projects over the lower flange of the rail and serves to keep that in place also.
order to prevent the key from being accidentally withdrawn a bolt is passed
vertically through it and the block.

Improvements relating to Railway Sleepers.
I, JOHN RANDOLPH GREEN, of Woodstock, Bibb County, Alabama, U.S.A.,
Inventor, 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 :-
My invention relates to metallic combination railroad-ties in which "tie bars "
and "rail supports" are joined to "rail sleepers" and secured in position by "slot hole
keys," and bolts operated in conjunction with the rails; and the object of my
invention is, first, to provide a continuous "rail bearing" with facilities for proper
adjustment in making curves; second, to afford a safe device for securely holding
the rails, independent of spikes or wedges. These objects I attain by the
mechanism illustrated in my drawings.
Figure 1 in my drawings, is a top side and near end view of one section of the
sectional rail sleeper as it appears after the removal of all connecting parts;
Fig. 2 the tie bar with the turned down ends, for the purpose of connecting
the sectional rail sleepers.

Fig. 3, is the top side of slot hole key, on cover plate, which enters key seat E in
Fig. 1 on top of Fig. 2.

Figs. 4 and 4' are top side views of the rail support and tie brace.
Fig. 5 is the reverse side of Fig. 3.
Fig. 6 is the reverse side of Fig. 1, which may be flat and solid, or hollowed out
as desired;
Fig. 7 bolt for hole n in Fig. 1.
Fig. 8 is a view of the parts in place, ready to receive the rail.
The view of the "rail sleeper" shown in Fig. 1 is coupled to its duplicate section
by the "tie bar" shown in Fig. 2, which lies directly across the road bed in the
same position as that of a wood-tie, each end of the tie bar," c', and c¹, shewn in
Fig. 2. enters the groove o, and mortice c, in the end of each section of "rail
sleepers" shown in Fig. 1. The ends B of the "rail supports," shown in Fig. 4,
drop into the dovetail notches B₁ on each side edge of the "rail sleepers" shown
in Fig. 1. The rail lies lengthwise on top of "rail supports" shown in Fig. 4., and
directly across "rail sleepers" in seat, H, shown in Fig. 1, with outside flange of
rail under lip m, m, on top of rail sleepers shown in Fig. 1. The end 9 of "slot
hole key" shown in Fig. 3 enters end g₁ of key seat E, of "rail sleepers shown
in Fig. 1, and is driven up on top of "tie-bar" shown in Fig. 2 until it is tight on
top of inside flange of rail, then by passing bolt n' shown in Fig. 7, up through
hole 1, in "rail sleeper" shown in Fig. 1 and on through the slot hole i of part, E',
shown in Fig. 3, and the nut being wrenched down tight upon the bolt shown in
Fig. 7, secures together my "combination tie" all parts of which may be made of
steel, and the several parts being dependent upon each other, mutually contribute
to produce the combination claimed, and the slipping and sliding, usual to other
ties, is consequently prevented.
Figs. 5 and 6, show the reverse sides of Figs. 3 and 1, and Fig. 8 is an illustration
of one part of the "rail sleeper" shown in Fig. 1, with a broken section of the
"connecting bar" F shown in Fig. 2 and two broken sections of "rail supports" F
shown in Fig. 4, all in connected position with "slot hole key" shown in Fig. 3,
driven up, to receive the rail. The hole y, in outside end of "rail sleeper" shown
in Fig. 1, is to receive a bolt only when the tie is laid on a bridge or trestle.
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 with a metallic railroad tie, of a sectional rail sleeper, said
tie having a groove, o, a mortice, c, a key seat, E, a rail seat, H, a flange lip, m, m,
two rail support notches B', and having bolt holes, n and y, all substantially as
set forth.
(2.) The combination with the tie having the mortice and groove with the tie bar
baving the turned down ends fitting therein, of the cover plate, E¹, for the purpose
herein set forth.
•
(3.) The combination in a metallic railway tie, of a rail support having dovetail
notches on each end, adjustable in dovetail notches B¹, B', on rail sleepers, adapted
to proper curvature of road, and solid rail bearing, and to prevent sleepers from
slipping and sliding, all substantially as set forth.
