An Improved Fire-Door Hanger.
THE Bureau of Fire Prevention is
laying a great deal of stress upon
the ease with which self-closing fire
doors operate, especially since the anti-
arson campaign has been in progress.
A great many fire doors have not been
approved after they have been installed,
becat4se there was evidence in their me¬
chanical construction which showed that
rust in the roller parts would, in time,
serve to prevent the free closing of the
door. The cut shows a device that the
J. E. Porter Company, of Ottawa, III.,
is putting on the market. No jar or vi¬
bration can offset the free action of the
wheels on the running plates, which are
double instead of single. In view of the
fact that the door is hung on center be¬
tween the rollers, which are set on rigid
axles, insures positive action, no matter
what the circumstances may be under
which they are expected to operate. The
runway is covered so that dust cannot
accumulate or water or dampness rust
or corrode it.
New Lock Set Designs.
The RuGsel & Erwin division of the
American Hardware Corporation of 96
Lafayette street is introducing new de-
i-'gns in builders' hardware, for inside
and outside trim. The castings are in
bronze or brass and can be furnished in
any of the standard or special finishes to
haimonize with decorative effects or the
finish of different rooms. In the Louis
XVI school there are the Ledoux and
LaLonde patterns, in Colonial, the Sey¬
mour, Copley and Camden designs and
the Monica in Mission finish.
A Telescopic Ash Hoist.
Since Borough President McAneny
has been enforcing the ordinance re¬
garding sidewalk encroachments, build¬
ing managers have been casting about
for an easy, yet efficient, solution of the
ash conveying problem. They may.
tlierefore, be interested in a device that
is being manufactured by Gillis & Geo-
hegan, of 537 West Broadway, which
consists of a hollow standard which tele¬
scopes. It is equipped with a powerful
brake, which permits of its use as a
lowering device for oi! barrels, etc. It
is not expensive, and yet it is so strong¬
ly built that it does not get out of order.
The illustrations show its compactness
under the sidewalk when not in use, and
how easy heavy barrels are lifted.
Swivel Faucet.
The accompanying illustration gives a
lair idea of the use of the swivel faucet
in connection with a special sink that
the E. B. Badger & Sons Co., of Boston,
builds. The swivel faucet does away
with the use of extra tap over the sink
and yet the supply of either hot or cold
water may be obtained readily. The
chief advantage of this design is in ob¬
taining water supply through one faucet
where otherwise four would have to be
provided.

QUESTIONS
and ANSWERS
Removing Varnished Tile Paper.
What is the best method for remov¬
ing varnished tile paper from walls and
treating lime spots after the paper has
been removed?
.Answer.—First remove the varnish
from the paper with aqua ammonia, then
soak the paper in the usual manner. If
Venice turpentine or Canada balsam has
been used in the paste it will be difficult
to remove the paper with hot water, but
a small portion of ammonia added to the
hot water will facilitate the work.
Paperhangers who have much work in
the line of removing wall paper use a
spraying steam apparatus made for the
purpose, in place of hot water. Lime
spots should be treated with vinegar
first, and when this has dried, should be
touched up with a thin size of wall var¬
nish and benzine.
Interest on Judgment.
From when does the interest on a
judgment date? Is compound interest
recoverable by law?
-â– \nswers: 1. Interest upon a judgment
dates from the time the judgment is
rendered. The courts generally award
interest at the legal rate, from the time
when a payment should have been made.
-\ creditor may charge interest on his
claim from the time it becomes due.
2. Compound interest is seldom recov¬
erable by law, even where it is express¬
ly agreed to. But when interest has ac¬
crued and is payable, it may be added
tn the principal by mutual agreement,
aud simple interest be charged thereon
and be collected.
Brick-Nogging.
Please define the expression: "Brick-
nogging." What is a "Brattice"? What
is Bessemer steel?
Answers: 1—Bricknogging is brick
work laid between timber framing. 2—
Brattice is a system of semi-supporting
partition, used chiefly in coal mines to
control gases. It is seldom used in
building construction except in cases
where it is desirable to keep street gases
or silt vapors from entering subsurface
workings to protect workmen. 3—Bes¬
semer steel is a variety of mild steel
sometimes called ingot iron, produced
from cast iron by blowing air through
it while in a molten state.
Clay Consistency in New Jersey.
Where can I obtain a description of
the various clay analyses in New York
and New Jersey deposits?
Answer: Write the State Museum of
New York, Albany, for copy of its lat¬
est bulletin on clay deposits of New
York state. For New Jersey data write
the Geological Survey, Trenton, N. J.
