ICE SCRAPER FOR TRACK MOTOR CARS‘

(Cl. 104—279)
This invention relates to what is believed to be
a. new accessory attachable to railway track mo
tor cars, the same being expressly constructed to
effectively dislodge and scrape ice from the track
rails to provide continuous and effective traction
and to thereby promote safety‘ to all'concerned.
In order .to provide a 7 more effective back
.119
and to thereby enable the operator of the car to
have de?nite control of said devices at all times.
Other features and advantages of the inven
tion will become apparent from the accompany
ing illustrative drawings and following detailed
description thereof.
In the drawings, wherein like numerals are
ground illustrative of the need for an invention
‘used to designate like parts throughout the views:
’of this type, a brief résumé of present prevail
Figure 1 is a side elevational view of what may
be called a conventional track motor car, show
ing one of the attachments applied thereto and
ing conditions is now given.
‘
During fall and winter when temperatures drop
to freezing and below, snow, ice and frost are
the main obstacles a railroad motor car has to
contend with. .This is especially the case in
occupying its ready-to-use operating position.
Figure 2 is a view of the attachment per se

with parts in section and elevation.

the attaching plate.
The snow alone is not so difficult, as it
can easily be brushed off the rail by the ordinary
snow ?angers, of which there are several types,
all more or less successful. These ?angers are‘
0 in most cases attached to car frame sides in
front of the front wheels and are raised or
lowered by various, methods. A coating of ice
underlying the snow and frozen to the rail is
quite common, or the ordinary frost or a coating
of ice alone on the railis a much more difficult
proposition.
The ordinary snow ?angers will
_ remove the loose snow, but do not have the least
e?ect on either the ice or frost. When a motor
car comes in contact with the above mentioned
,
Figure fl is a cross-section on a slightly en
larged scale, the section being on the line'4-4
of Figure 2.
In the drawings in Figure 1, the'conven 20
tional track motor car is denoted by the letter
A and includes a platform B, front wheels C,
and rear wheels D. The adapter of attaching
plate, which is of appropriate metal, is indicated
by'the numeral 5, and this is of suitable propor 25
tions and is bolted or otherwise secured as at 6
to supporting blocks or the like 1 provided on
the central marginal portion of the platform or
frame B. As will be hereinafter seen, when the
condition, whether equipped with snow flangers ' attachment proper is removed, this plate 5 con 30

stitutes a so-called running board.
The numeral 8 designates generally an adapter
A motor car operator may leave his station
?xture having a substantially triangular upper
with weather and rails favorable, but before he
arrives at his destination the weather may change
or he may run into a section of the country
where, due to atmospheric conditions, rails are
covered with a heavy coating of frost or sleet
immediately after a train has passed. It is with
4.34.0 such conditions in mind, coupled with my own
personal experiences in operating a motor car,
that I have, after ?ve years of experimenting,
etc‘., arrived-at what I know to be a practical and
fool-proof ice scraper.
In reducing to practice the principles ofathe
present inventive conception, I have found it
expedient and practicable to- adopt a structure
portion with the feature 9 thereof bolted as at
ID to the attaching plate 5. The feature H con 35
stitutes a diagonal brace and joins with the de
pending leg IZ, the latter feature constituting a
shield and riding in close proximity behind the
front wheel C. This feature l2 terminates in
spaced relation above the ball or head of the
track or rail,’ as is evident. At this-particular
point it is provided with suitable guides I3 and
M to accommodate the spring pressed slidably
mounted scraping blade l5. This blade is of
- appropriate'tempered steel and has its effective
working end properly sharpened, if so desired.
1_On its central and back portion it is provided
' with an integral screw-threaded nut IE to ac
comprising a pair of attachments applicable to
opposite sides of- the truck of the track car, these " commodate the screw-threaded end I‘! of the
attachments cooperating with and trailing‘ the plunger rod l8. The rod l8 extends up through i
front wheels to insure constant contact with the
ball or head ofthe rails, ‘whereby to insure re
a guide collar I9 on the under side of the at;
taching plate 5. There is a collar 20 on top of
liable results, the attachments'being such that
the plate through and beyond which the rod
the spring pressed scraping blades are susceptible - extends. - This extending portion of the: rod is

riser or collar 22.

The numeral 24 designates a
coiled expansion spring which surrounds the
plunger rod between the projectable and re
tractable nut l6 and the ?xed-abutment collar
l9. This spring maintains the stop pins 22 in
yieldable engagement with the keeper’ notch 25
