COMPLETE SPECIFICATION.
Improvements in Car Replacers.
I, JOHN MAXWELL DONNELLY, residing at Neihart, in the State of Montana,
Gentleman, 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:-
This invention relates to improvements in car replacers.
The object of the invention is to provide means for replacing derailed cars, the
device being reversible so as to be used on either rail.
In the accompanying drawings forming part of this Specification:
Fig. 1 is a plan view showing the device applied to the railway rails.
Fig. 2 is a longitudinal sectional view taken on the line - of Fig. 1, the
reversible plate D being removed.
Fig. 3 is an inverted plan view.
Fig. 4 is a side view, and
Fig. 5 is a front elevation.
A A designate the railway track rails to which the device is secured.
B designates a metal plate which converges toward the front end and is provided
with side flanges b,, which extend upward for a suitable distance. The
plate is tapered at its rear end and increases gradually in thickness toward its
front where it is provided with two upwardly projecting blocks C, C, the rear
edges of which are slightly curved for the better connection therewith of a
reversible plate D. The underside of the plate B has a suitable filling E pre-
ferably of wood which forms practically a flat under surface which will bear
upon the ties.
To the front corners and to the underside of the plate B are pivotally attached
blocks d, and adjacent thereto are formed projections e, which are apertured to.
receive a bar, said bar passing through an extension F of the base plate which
is provided with a thumb-screw for securing the bar in place against the web of
the rail.
Perforations 9, are formed in the plate B near its rear end through which
passes a bolt for adjustably connecting thereto an arm G, the outer end of
which is bent to engage with the opposite rail. By means of this arm and the
clamp, consisting of the block d, and sliding bar, the plate B is secured to the
rails A, A, and the angle of the plate may be varied to suit the exigencies of
the case with respect to the car wheels it is desired to replace.
A. bar H is secured to the plate B adjacent to one of the side flanges by means
of bolts h, and i, and said bar tapers rearwardly as shown, the front end being so
located that a space is left between the same and the projection C through which
the flange of the wheel will pass and be guided to the rail A.
When the wheel moves on the plate B it will first contact with the hypothenuse
of the triangular block D and be guided thereby to the bar H.
It will be noted that the parts G, D, and H, can be shifted from one side of the
plate to the other to adapt the device to the other track when required.
An ordinary bridge can be used in connection with this device to replace the
wheel on the other track, or another one of my improvements can be applied for
the purpose.
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 :-
1. In a car replacer, a plate B provided at its front end with a pivoted block

page_text: and adjacent thereto a clamp for securing the front end to a rail, an arm secured
near the rear end of the plate for engagement with the opposite rail, the plate B
having side flanges and ways for the car wheel, substantially as set forth.
2. The combination in a car replacer, of a plate B having means for securing
the same to the rails, said plate having side flanges b, b, and raised portions C, C,
forming guide ways at the front end of the plate, a removable bar H inclined at
each end and a triangular reversible block D, substantially as set forth.
3. In a car replacer, the combination of the plate B tapered and provided with a
base E, side Hanges as shown, blocks C, C, adjacent to the front ends of said
flanges, pivoted blocks d, d, rests e, e, through which a sliding bar passes, a
reversible plate D secured to the plate B, and a removable bar H having inclined
ends, the parts being constructed substantially as set forth.
Dated this 30th day of November 1891.
