PROVISIONAL SPECIFICATION.
An Improved Appliance for Cleaning the Channel and Wheel Face of
Grooved Tramway Car Rails from Stones, Gravel, and other
Obstructions.
We, EBEN HILL JULIAN, Commercial Traveller, Sneyd Lodge, Sneyd Park,
Bristol, and CHARLES MILLARD, Engineer, 40, Summer Hill, Bath Road, Bristol
do hereby declare the nature of this invention to be as follows:-
The appliance is an attachment for tramway cars automatically adjusting
itself to the curves of rail & "play" of springs of car, &c., so that scraper &c.
which may be attached are always in contact with rail. Running in channel
of rail is 6
a tongue" (or tongues) fixed, or free to revolve, & provided with pro-
jecting flange, and attached to car by a flexible, pivoted, or sliding connection,
which permits of it (or them) moving laterally to right or left. The said
"tongue" (or "tongues") being pivoted to end of connection and retained in
channel of rail by a spring or other yielding pressure, thus forming a “pilot”
or guide for scraper or other appliance which may be attached, and ensuring
their (or it) following the rail & being at all times in close contact with it.
If desired "tongue" or guide may be used as scraper and guide combined.
Dated this 22nd day of July: 1899.

An Improved Appliance for Cleaning the Channel and Wheel Face of
Grooved Tramway Car Rails from Stones, Gravel, and other
Obstructions.
We, EBEN HILL JULIAN, Commercial Traveller, Sueyd Lodge, Sneyd Park,
Bristol, and CHARLES MILLARD, Engineer, 40, Summers Hill, Bath Road, Bristol
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 :-
The object of this invention is to provide an appliance for attachment to
tramway cars, automatically adjusting itself to the curves of rails and "play"
of springs of car, so that rail scraper or cleaner which may be attached" is
always in contact with rail under normal conditions but on meeting an irre-
movable obstruction automatically releases itself.
Fig. 1 shows the apparatus in normal position for one side of car, A is under
frame of car, M is car wheel, B is iron pillar, bolted to under frame of car,

page_text: C and C are clips revolving freely on B in recesses or grooves, and provided
with lugs, and D are arms secured to before named lugs by pins or bolts
on which they work freely in a vertical direction, E is a connecting arm
attached to D, D' by pins or bolts, F is a spiral spring secured at ends to
lug and to 1 and E and in tension. The arm E carries two projections L
and L having circular. holes in each in which arm G revolves freely. The
spindle G is prevented from sliding vertically in its bearings by a lins pin or
nut at L and shoulder at L'. J is flanged guide wheel, H is bracket carrying
guide wheel and scraper and connected with G by a pivot or bolt, I is scraper,
Kis spiral spring attached to end of bracket H and to spindle G, and in
tension. Fig. 2. Shows apparatus when automatically released on meeting an
irremovable obstruction, the action is as follows, the spring F exerts sufficient
pressure on wheel and scraper to retain them in groove of rail under ordinary
conditions thus as the car travels over rail the scraper I removes ordinary
obstructions. In case however of meeting with an irremovable obstruction the
retarding pressure on I communicates itself to arms D, D' causing them to
approach an horizontal position thus lifting spindle arm G, at the same time
the spring K exerts a pull on scraper end of pivoted bracket H causing guide
wheel J to remain in groove of rail and ensuring return of I to groove, on
clearing obstruction.
Having now particularly described and ascertained the nature of cur said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The apparatus for attaching to tram cars for the purpose of clearing the
rails, arranged and operating in the manner substantially as herein described
and illustrated.
2. In apparatus for attaching to tram cars for the purpose of clearing the
rails, the combination with a bracket and arms such as B D D and E of
automatic release as provided for by revolving spindle G, tension spring K and
pivoted bracket H with guide wheel J substantially as and for the purpose
herein described and illustrated in accompanying drawings.
Dated this Twenty-third day of April 1900.
