JOHN P. H. BAILEY, OF BIJRNET, TEXAS.
RAIL-JOINT.Specification of Letters Patent.
Patented March 31, 1908.
Application filed May 6, 1907. Serial No. 372,125.
To all whom it may concern:
Be it known that I, JOHN P. H. BAILEY, a
citizen of the United States, residing at Bur-
net, in the county of Burnet, State of Texas,
5 have invented certain new and useful Im-
provements in Rail-Joints; and .I do hereby
declare the following to be a full, clear, and
exact description of the invention, such as
will enable others skilled in the art to which
10 it appertains to make and use the same.
This invention has relation to that class of
railway-rail joints that have overlapping
ends, so formed as to do away with the ne-
cessity of fish bars or plates.
15 It is the object of my invention to so form
the overlapping ends that they will mutually
and evenly support the weight that may be
brought thereon throughout the joint, and
so that the greater the weight brought upon
20 them the more complete will be the union of
the jointed parts, absolutely avoiding the
yielding of one end without a like yielding of
the other.
The nature of the invention is fully and
25 clearly ascertainable from the device por-
trayed in the annexed drawing, forming a
part of this specification, in view of which it
will first be described with respect to its con-
struction and mode of operation, and then be
30 pointed out in the subjoined claims.
Of the said drawings-Figure 1 is a side
elevation of the meeting ends of two 'rails
joined in accordance with my invention.
Fig. 2 is a view of the side opposite to that
35 seen in Fig. 1. Fig. 3 is a plan of the same.
Fig. 4 is a bottom view of the same. Fig. 5
is an end view of each part. Fig. 6 is a trans-
verse section.
Similar numerals of reference designate
40 similar parts or features, as the case may be,
wherever they occur.
In the drawings A designates the meeting
end portion of one rail and B the meeting end
portion of the other rail.
45 The web 1 of the rails at their meeting and
overlapping portions, and for a slight dis-
tance beyond the overlapping portions is
thickened, as is clearly indicated in the draw-
ings, the sides of the thickened portions be-
50 ing inclined from their upper edges out-
wardly.
The tread 2 of the overlapping ends is di-
vided on a line 3 extending in a plane trans-versely of the longitudinal extension of the
rails near one end of the thickened parts of 55
the web 1, and the latter is divided on one
side on a vertical line 4, in the plane of the
line 3 on the tread while on the opposite side,
the division line extends from the line 3 hori-
zontally below the ball of the end A to near co
the opposite end of the thickened part of the
web, whence it extends on a vertical line 5,
to the base of the rails.
Between the division lines 3 and 5, each
overlapping end is cut away on opposite 65
sides on lines in the form of an ogee molding,
the molding of one part being the reverse of
the other, so that when the two ends are joined
by an endwise movement the end portions will
not only overlap, but become interlocked on 70
a matching ogee surface, in such manner as
to form a complete union that. cannot 'be
broken by lateral stress or strain without
breaking at least one-half of at least one of
the end portions to the full extent that it 75
overlaps the other.
By dividing the end portions between the
tread and the base of the rails on an ogee
surf ace, I am enabled to leave the tread 2
intact except as to the single transverse so
divisional line 3, and to so join the overlap-
ping ends that it is practically impossible to
separate them laterally. At the same time
the vertical strain brought upon the tread
of the rails is borne equally by each over- 85
lapping part.
The overlapping portion of the end of the
rail A is cut from the lowermost margin of
the ogee surface to the base on an inclined
line 6, leaving the base flange 7 intact. This 90
construction affords opportunity for notch-
ing the side edges of the base as at 8 for the
driving of the usual spikes 9 in the ties at the
sides of the bases of the rails to maintain
them in place laterally. 95
By my improvement I not only secure a
perfect interlocking of the jointed ends so
as to secure their perfect alinement under all
conditions without fish bars or plates, but
also without chains or other vertical supports 100
than is afforded by the joint itself.
One of the peculiar advantages of the
matching ogee surface of union between the
overlapping ends of the rails, is that it con-
tains no angular turns. 105
The invention obviates the necessity ofNo. 883,508.
