page_text: I, EDWARD DYER DOUGHERTY of Philadelphia, in the County of Philadelphia
and State of Pennsylvania, Manufacturer, 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 an improvement in Slot Irons for Cable Railroads, the
object of the same being to provide a strong and durable slot iron that can be
easily and quickly adjusted to increase or decrease the size of the slot through
which the grip passes. A further object is to provide the adjustable slot iron with
a removable wearing face, whereby the parts exposed to wear can be renewed in a
short space of time without the necessity of tearing up the road bed or stopping
travel, and with these ends in view my invention consists in the parts and
combinations of parts as will be more fully described and pointed out in the
claims.
In the accompanying drawings, Fig. 1 is a perspective view of a slot iron
embodying my invention, and Fig. 2 is a view in transverse section showing the
iron applied to one form of supporting bracket.
A represents a bracket of any approved design, having a slot a for the passage
of the grip to the cable located within the tube B and seats b for the rails.
The slot irons C seated on the bracket on opposite sides of the slot, and each
consists of a broad base c, a web c¹ extending upwardly from the central portion of
the base, and inclined inwardly and an inwardly projecting flange constructed
integral with the web c¹ and forming a seat for the plates D. The base of each
slot iron is provided at suitable intervals apart on opposite sides of the web c² with
the transverse elongated openings d, through which the bolts E which secure the
slot irons to the bracket, pass. The base of the slot iron may also have recesses
therein, communicating with the bolt openings d for the heads of the bolts, but
the device is just as efficient if the heads of the bolts rest on the upper surface of
the base.
The openings d are of a length sufficient to permit the slot irons to be moved
inwardly to take up the wear, and as this inward movement is comparatively
small the bolt heads can be made large enough to cover the openings and prevent
dirt from entering therein. Instead of the above, the bolts can be provided with
sheet metal washers below the heads and answer the same purpose.

page_text: The bolts E pass through the base and brackets and are secured into screw
threaded openings in the brackets, or they can project below the bracket and be
secured by nuts as shown in the drawings. The upper face of the flange c' is flat
and forms a seat or rest for the wearing plates D, which in the present instance
are provided with corrugated upper surfaces for the purpose of preventing horses
from slipping thereon. These wearing plates are removably secured in position by
bolts or otherwise, and each is provided with an inwardly projecting lip which
latter overhangs the inner edges of the flanges of the slot irons and takes all the
wear occasioned by contact with the grip. The upper surface of this inwardly
projecting lip is concaved to prevent horse shoe calks from becoming wedged or
sticking.
By means of the above improvement I am enabled to adjust the slot irons to
take up any wear, and am also enabled to remove the portion subjected to the
wear and replace it at a small cost in a few moments without stopping traffic.
It is evident that numerous slight changes in manner of securing the slot irons
to the brackets might be. resorted to, hence I would have it understood that I do
not confine myself to the exact construction shown and described but consider
myself at liberty to make such changes as fairly fall within the spirit and scope of
my invention.
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
1st The combination with a slot iron, of a removable wearing plate secured to
the upper face of the iron and overhanging the inner edge thereof.
2nd The combination with a slot iron, of a corrugated wearing plate removably
secured to the upper face thereof.
3rd The combination with a laterally adjustable slot iron, of wearing plates
removably secured to said slot irons.
4th The combination with a bracket and slot irons adjustably secured thereon,
of wearing plates removably secured to said irons substantially as set forth.
5th The combination with a bracket, of the slot irons, consisting essentially of
the base, the web extending upwardly from or approximately from the centre of
the base, the inwardly projecting flange, and a removable wearing plate, sub-
stantially as set forth.
