PHILIP NOONAN, OF OVERTON, TEXAS.
RAILROAD-TIE.
SPECIFICATLON forming part of Letters Patent No. 554,372, dated February 11, 1896.
Application filed May 21, 1895, Serial No, 550,042. (No model,)To all whom it 7ay concern:
Be it known that I, PHILIP NOONAN, a citi-
zen of the United States, residing at Overton,
in the county of Smith and State of Texas,have
5 invented certain new and useful Improve-
ments in Railroad-Ties; and I do declare the
following to be a full, clear, and exact descrip-
tion of the invention,such as will enable others
skilled in the art to which it appertains to
io make and use the same, referencebeinghad to
the accompanying drawings, and to the letters
of reference marked thereon, which form a
part of this specification.
The special object of the invention is to
15 make a railroad cross-tie of metal, built up
firmly and secured to the rails without screws,
bolts, rivets, cushions or other appurtenances.
Figure 1 of the drawings is a plan view show-
ing my invention applied; Fig. 2, a longitudi-
20 nal section of one of the rail-supports on dot-
ted line 4 4, and Fig. 3 a cross-section of Fig.
2 on dotted line y y of Fig. 1. Fig. 4 is a per-
spective view of the cross-tie.
In the drawings, A represents the railroad
25 cross-tie as a whole. B is the bottom thereof,
preferably made of rolled steel having a thick-
ness of about one-half an inch and provided
with two stiffening-ribs b b projecting up-
wardly about one and three-quarter inches.
30 In the middle of the tie Imake the two longi-
tudinal bottom openings b' b', from which the
metal is bent to form the upright flanges b2
b2. This construction increases the rigidity
and diminishes the ground bearing near the
35 middle, so as to prevent the tie from becom-
ing " center-bound " after being in use under
the railroad-track.
C C represent the two track-supports of the
tie, they being arranged at the proper dis-
40 tance apart between the ribs or flanges b b
and being shells of pressed steel or malleable
iron about half an inch thick, open at the bot-
tom and provided with the openings or holes c.
The rail-supports C are held down to thebottom plate B by bending or crimping the
upper parts of the ribs or flanges b b inwardly,
so as to enter the four side openings, as shown
in Fig. 3 of the drawings.
D represents the clips and E the braces
which secure the rails to the supports C, each
of the latter permitting the use either of a clip
or brace on that part of the tie which is outside
of the rails. I preferably make the clip and
brace of pressed steel, each in a single piece
and both so constructed as to allow for a free
half-inch vertical play of the rail. They are
also made so that in case of a violent shock
they will break off flush with the tie without
injury thereto, and are pivoted near the outer
end in a groove c', but are stepped at c2 to
engage corresponding steps in the support C.
This takes the strain off the pivot while it ef-
fectually prevents the track from spreading
or getting out of alignment.
Having thus described all that is necessary
to a full understanding of my invention, what
I claim as new, and desire to protect by Let-
ters Patent, is-
1. An upwardly-ribbed cross-tie A, the
track-supports C C between said ribs, and the
clips or braces D and E secured to and in said
supports, all combined and arranged as shown
and described.
2. A railroad-tie having the rail-supports
provided with side openings and a bottom with
the ribs b b to enter said openings as and for
the purpose set forth.
3. In railroad-ties where the rail is not sup-
ported directly on the tie, a clip or brace piv-
oted in a groove c' of the support and stepped
at c2to engage corresponding steps of the sup-
port as and for the purpose set forth.
In testimony whereof I affix my signature
in presence of two witnesses.
PHILIP NOONAN.
