Improvements Connected with Tram Rail Groove Cleaners or
Scrapers.
We, JOHN RECORD, of 23 Kenninghall Road, Clapton, Middlesex, Gentleman and
HENRY JOBLIN JORDAN, of 68 Lucy Road, Bermondsey, Surrey, Smith, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to so arrange the scraping mechanism of tram rail
groove and tread cleaners that said tool carrier has a free motion for automatic
adjustment to allow for wear besides being coupled to appliance for raising and
lowering by hand.
The invention is applicable to engines or cars as well as to trolleys.
For the purpose of our invention, we suspend the scraping mechanism from the
double-helical-spring-fitted-gauge-bar by which lateral play of the scraping tools in
pairs are secured such as by the plan or method referred to in Patent No. 12641
granted to Edwards and Record on the 22nd day of October in the year 1885.
The scraping tool by our present invention is adjustable in a shoe, this being hung
from a connecting link or shackle provided with stops which limit the motion of the
scraper to pass obstacles, said scraper having a tail piece connected by screw bolts and
a parbuckle to a spring fitted within a link hung from a rod or bar at about the
transverse mid distance of the vehicle. The connecting link or shackle is mounted
upon the guage bar as described in Edwards and Record's Specification before
mentioned so as to connect the two scraping tools in pairs either at the end of the car
or engine or between the wheels as desired, said guage bar having helical springs on
either side of the shackle to allow of lateral action when moving round curves, said
guage bar having a double ended lever connected by rods to another double ended
lever, so that a handle connected thereto and working over a quadrant or otherwise
may determine the angle and for adjustment.
The guage bar is carried by brackets and is held therein by half caps fixed in
position by bolts passing through the brackets and bearing on the half caps."

page_text: Each shoe has one or more chocks or lugs for abutting against stops or stop pieces
which may be cushioned to subdue or soften concussions.
Each shoe of the pair has independent play for passing obstacles but are returnable
by the spring before referred to in the link or instead of the link a strap or cylindrical
cup may contain the spring.

Improvements Connected with Tram Rail Groove Cleaners or
Scrapers.
We, JOHN RECORD, of 23 Kenninghall Road, Clapton, Middlesex, Gentleman
and HENRY JOBLIN JORDAN, of 68 Lucy Road, Bermondsey, Surrey, Smith, 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 so arrange the scraping mechanism of tram rail
groove and tread cleaners that the tool carrier has a free motion for automatic adjust-
ment to allow for wear besides being coupled to appliance for raising and lowering by
hand.
The invention is applicable to engines or cars as well as to trollies.
For the purpose of our invention, we suspend the scraping mechanism from the
double-helical-spring-fitted-guage-bar by which lateral play of the scraping tools in
pairs are secured such as by the plan or method referred to in Patent No. 12641
granted to Edwards and Record on the 22nd day of October in the year 1885.
The scraping tool G by our present invention, which we show in the annexed
drawings Figures 1 and 2, is adjustable in a shoe H this being hung from a con-
necting link or shackle a provided with stops which limit the motion of the scraper G
to pass obstacles, said scraper carrier H having a tail piece c connected to a spring e
fitted within a link fhung from an eye g on the vehicle.
The connecting link or shackle a, Figure 3, is mounted upon the guage bar Q pro-
vided with springs P, P, as described in Edwards and Record's Specification before
mentioned so as to connect the two scraping tools in pairs either at the end of the
car or engine or between the wheels as desired; each tool carrior H is on a bolt d

page_text: having helical springs h, h, on either side to allow of lateral action when moving
round curves, said guage bar Q having a lever i connected by a rod j, so that a
handle K connected thereto and working over a quadrant or otherwise may determine
the angle at which the tool shall work.
The guage bar Q is carried by brackets k, Figures 1 and 4, and is held therein by
half caps l, m, fixed in position by bolt or a cottar n passing through the brackets and
bearing on the half caps L.
Each shoe H has one or more chocks or lugs p for abutting against stops or stop
pieces which may be cushioned to subdue or soften concussions.
Each shoe El of the pair has independent play for passing obstacles but are return-
able by the spring e before referred to in the link for instead of the link a strap or
cylindrical cup may contain the spring e.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is
The combination of an adjustable shoe H and scraper tool G arranged with the
other appliances a, d, h, e, f, and has shown in the annexed drawings with the guage
bar as and for the purposes described.
