PROVISIONAL SPECIFICATION.
Improvements in Bar Hooks and like Attachments for Railroad
Wagons and Vehicles.
I, GEORGE ERNEST RAKE, of 40 Mill Street, Aberdare in the County of
Glamorgan, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in bar hooks, triggers, or like
attachments for arresting the descent of a railroad wagon or vehicle on an
incline.
The object of my invention is to construct a bar that shall be more suitable
for resisting the stress imposed upon it by the vehicle, and more easily pass
over the rollers, and other projections on the track, than those at present in
general use.
In carrying my invention into effect I construct the bar or trigger for
attachment to the rear of the ascending train of vehicles on an incline, from cast
steel or other material, providing a jaw at one end for embracing the shackle
which is attached by the eye or hook pin to the hitching plate or ordinary draw
bar of the wagon or other vehicle. I extend one end or side of the shackle
sufficiently beyond the eye or hook pin to enable the trigger to be pivoted thereto
by means of an independent pivot pin. The stem of the bar or tiigger,
terminates in a foot or pointed end, which, in the event of the detachment of the
vehicle from the hauling rope, or from the front wagons, will be forced into the
track or against a sleeper or other projection by the detached wagon in its
tendency to descend the incline, and thus the wagon will be safely sustained in
position upon the track.
If the momentum or energy of the detached wagon should be greater than can
be resisted by the bar, the pivot joint herein before described permits of a slight
descent of the wagon whilst the foot of the bar remains stationary with the result
that the wagon becomes de-railed and is thrown across the track.
In the ascent of an incline the bar rises and falls upon its pivoted joint and
thus freely passes over the sleepers, rollers, and other projections on the track.
I do not limit the application of my invention to the construction of any
particular form or pattern of bar hooks or like attachments but make such
modifications as may be necessary to suit the requirements of varying services.
Dated this 28th day of May 1895.

Wagons and Vehiclės.
I, GEORGE ERNEST RAKE, of 40, Mill Street, Aberdare, in the County of
Glamorgan, Engineer, 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 bar hooks, triggers or like
attachments for arresting the descent of a railroad wagon or other vehicle on an
incline.
The object of my invention is to construct a bar that shall be more suitable
for resisting the stress imposed upon it by the vehicle, and more easily pass
over the rollers and other projections on the track, than those at present in
general use.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to;-
Figure 1 is an elevation of a complete bar hook constructed in accordance
with my invention.
Figure 2 is a plan of the bar alone, and Figure 3 a similar view of the
shackle.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I construct the bar or trigger A, for
attachment to the rear of the ascending train of vehicles on an incline, from cast
steel or cther material, providing a jaw A¹ at one end for embracing the shackle B
which is attached by the hook pin passing through the eye B' to the hitching
plate or ordinary draw bar of the wagon or other vehicle. I extend one end or
side of the shackle sufficiently beyond the hook pin to enable the trigger to be
pivotted thereto by means of an independent pivot pin passing through the eye B'.
The stem of the bar or trigger terminates in a foot or pointed end such as A'
which, in the event of the detachment of the vehicle from the hauling rope, or
from the front wagons, will be forced into the track or against a sleeper or other
projection by the detached wagon in its tendency to descend the incline, and thus
the wagon will be safely sustained in position upon the track.
If the momentum or energy of the detached wagon should be greater than can
be resisted by the bar, the pivot joint at B2 herein before described permits of an
upward movement of the rear end of the wagon whilst the foot of the bar remains
stationary with the result that the wagon becomes de-railed and is thrown across
the track.
In the ascent of an incline the bar rises and falls upon its pivotted joint and
thus freely passes over the sleepers, rollers and other projections on the track.
For running the wagon in a reverse direction the tail rope is hitched at A³, and
the pull on the same will thus hold the bar hook off the ground.
.
I do not limit the application of my invention to the construction of any
particular form or pattern of bar hooks or like attachments but make such
modifications as may be necessary to suit the requirements of varying services.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.-
1. In bar hooks and like attachments for railroad wagons and vehicles, the use
of a bar or trigger having a pivot connection with the hitching plate shackle or
draw bar attachment, substantially as and for the purposes described.

as illustrated in the
substantially as and for the purposes described and
accompanying drawings.
