"
COMPLETE SPECIFICATION filed by the said Elisha Newcomb at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 6th August 1874, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELISHA
NEWCOMB, of Westbrook, in the County of Cumberland, and Stato of
Maine, one of the United States of America, Mechanic, send greeting..
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN CAR REPLACERS," and have petitioned Her Majesty to grant unto me,
my exccutors, administrators, and assigns, Her Royal Letters Patent for

page_text: the same, and have made solemn Declaration that I am the first and
true Inventor thereof.
NOW KNOW YE, that I, the said Elisha Newcomb, do hereby declare
that the following Complete Specification, under my hand and scal, fully
describes and ascertains the nature of the said Invention, and in what 5
manner the same is to be performed in and by the following statement,
reference being had to the accompanying Drawings:-
The general purpose of my Invention is to provide a device for tho
replacing of cars upon the rails, when the same have by accident or
otherwise become displaced therefrom.
My Invention consists in a novel structure or combination of inclined
planes with other devices to accomplish this purpose.
One of the parts of my Invention is placed on the inside of one of the
rails, and is held firmly in its proper position by hooks or points at one
end, and by a detachable brace at the other.

The other part of my Inventien consists of a double inclined plano
rising to a heighth sufficiently greater than the rail to carry the flange of
the wheel over the rail, and having at the same time an inclination of
its upper surface toward the rail, so that when the wheel is sufficiently
clevated it will slide over toward and take its proper place upon the rail. 2
Both of these parts are placed upon the cross ties and held in position
on them by hooks, points, or projecting bolts.
In the accompanying Drawings Fig. 1 shows a top plan view of my
Invention placed in position upon the cross ties.
Fig. 2 is a side view of the detachable brace to be herein-after 2
described.
Fig. 3 is a view in section of one of the parts of my
Invention.
I will first describe that part which is placed upon the inside of the
rail and is shown in position in Fig. 1.
carries the two supplemental tracks b, c.
It consists of a bed a which
It has further the frog d 8

page_text: imbedded into or to pass over the edge of one of the cross ties to aid in
holding the device in position.
'
I will now describe the operation of this part of my Invention. Those
wheels of a car which after the displacement are on the inside of one of
the rails, are drawn up on to the bed a in such manner that the tread of
the wheel will rest upon one of the two supplemental rails b, c, 'which
is next to or in contact with the inside of the rail. The position of the
frog & controlls the position of the tread of the wheel relative to the rails
bor c. As illustrated in Fig. 1; the frog is so placed that the wheel
must pass on to the supplemental rail c. The cross bar fregulates tho
position of the frog d. This cross bar slides under the rails b and c, and
tlic entire device is placed close to the inside of the railway track; the
inner end of the cross bar striking the base of the rail pushes the frog
over into proper position. This device to be placed on the inside of tho
track is capable of being applied to replace cars in either of the two
directions they may be traveling. The brace has the socket & to fit
over the forward end of the bed a, as illustrated in Fig. 1. The bent
portion j fits into the hollow on the side of one rail, and the end & into
the same portion of the opposite rail. Thus the bed is kept firmly
pressed against the inside of one of the rails of the track. Hooks or
points upon the ends of the cross barf togather with the points on the
other parts of the device aid in holding the said device in position by
means of said points penetrating the cross ties. The operation of this
part of my Invention is evident. The wheel is carried upon the supple-
; mental rail and parallel with the track until in position to be run on to
the rail by the operation of the other part, of my. Invention;, which I will
now describe. This part as has already been specified consists of a
double inclined plane, whose upper surface shelves toward the rail of
the track on the outside of which it is located. The purpose of the
transverse inclination of the top surface is that the car wheel turning on
it shall slide inward and downward, and thus drop into proper position
on the track. The effect of this sliding of the wheel on the part last-
referred to upon the wheel which is drawn up on the part placed on the
inside of the other rail is next to be obscrved.
:

For greater distinctness I will here designate that part of my
Invention illustrated in Fig. 1, which is placed inside the rail, by the
letter A, and the other by B. The highest part of the part B is placed
exactly opposite the end of the one of the two supplemental rails & or c,

page_text: which happens to be used at the same time. When therefore the wheels
by the weight of the car and the operation of the frog & slide down on
to the rail, next to which is placed the inclined plane B, the wheel on
the part A, being at the end of the supplemental rail b or c, is pushed
over so as to be placed in proper position on the rail next to the said
part A.
It will bo observed that the frog d is made wedge-shaped, with tho
point of the wedge toward the wheels to be replaced. It has also
slightly beveled sides. The operation of the frog is in consequence to
push the wheel over on to the track near to which the frog is placed, 1
and thus it operates to facilitate and materially aid in not only the
direction of its wheel to its proper track, but also the sliding down of the
opposite wheel on the shelving top surface of the part B.
What I claim as my Invention and desire to secure by Letters Patent
is, the combination of the two parts A and B arranged and con- 1
structed as described, and the brace y to hold the part A in position, as
herein set forth.
In witness whereof, I, the said Elisha Nowcomb, have hereunto set
my band and seal, this Eighth day of July, in the year of our
Lord One thousand eight hundred and seventy foun
