CATALOGS
BABBITT METAL.-The Magnolia Metal Company, 113 lank
street, New York, have issued a booklet which they call "Mag-
nolia Talking Points," and which contains information concern-
ing babbitt metal.
Pusa BUTTON CONTROL-The General Electric Company.
Schenectady, X. Y., has issued bulletin A-4070, describing the
electrically operated remote control switch. This switch is
especially adapted for controling group drives in shops where
is desired to have instantaneous stops in various parts of che
shop.
ELECTRIC APPARATUS-A small catalog from the Spragne
Electric Works of the General Electric Co., New York, illus-
trates and briefly describes sonte vi the specialties manufactared
at that plant. These include principally electrical equipments for
buildings, such as generaams, gasolene-electric generaling sets,
switchboards, motors, electric fans, lamps, etc.
PIPE UNIONS. A leaflet from the Jefferson Union Company,
Lexington. Mass., demonstrates, by means of lustrations and
brief description, the advantages of the Jefferson unions. These
unions are so constructed that a wrench of any width of face
can be used and the threads are so placed that there is no
danger of their being injured by the wrench. The pipe threads
are made with a taper tap.
GRAPHITE PRODUCTS. A catalog of 104 pages devoted ex-
clusively to Dixon graphite products is being issued by the
Jos. Dixon Crucible Company. Jersey City, N. J. The catalog is
most complete, is thoroughly illustrated and includes a price
list. It covers crucibles in capacities frem a few emces to one
thousand pounds. lubricating graphites of all kinds, graphite
paints, graphite specialties, pencils and erasers.
PNEUMATIC TOOLS-Bulletin No. 124 from the Chicago Pnen
matic Tool Company, Fisher Building. Chicago, is devoted to
pueumatic riveting, chipping and calking hammers. These are
shown in a full range of sizes and capacities, and tables are
included giving the specifications of each tool. An extract from
an article by G. 11. Hays on the care of pneumatic hammers is
included. Bulletin No. 130 from the same company gives in-
structions on the lubrication of pneumatic tools.
Too STEELS AND MANUFACTURING COSTS.-A booklet is being
issued by the Firth-Sterling Company, McKeesport, Pa., for the
purpose of presenting and proving the statement that if a tool
steel will increase the output of a machine one per cent., an in-
creased cost of 50 per cent. in the price of the tool steel is
justified. It is stated in this argument that one-sixth of a
pound of high speed steel is used on an average 20 in. latke each
day. This is based on work such that the tool requires grind
ing five or six times a day.
SHAPE BOOK-The Illinois Steel Company, Chicago, T., has
issued a leather bound book on structural shapes. The book
is very thoroughly illustrated with detailed drawings of the
various shapes and devices, containing the regular standard
structural beams, as well as agricultural beams, concrete re-
enforcement bars. pipe bands, miscellaneous mil shapes, rails,
etc. In the back of the book there are tables containing the
weights of different sizes of flat rolled steel, wire gages, areas
and circumferences of circles. etc.
THREADING MACHINERY-Catalog No. 21 from the Landis
Machine Company, Inc, Waynesboro, Pa., contains 79 pages,
and illustrates bolt threading, pipe and nipple threading, bolt
pointing and nut tapping machinery, screw cutting, die heads
and special threading machines. These are shown in a full
assortment of sizes. and each is accompanied by a table ci
specifications and a list of the equipment furnished. The cata-
log opens with a discussion of the features of the Landis die
as compared with those of other threading tools; the reasons
for its development and the success it has attained in actual
practice.
MIKATOS FOR THE CHESAPEAKE & OHIO-Dulletin No. 1012
from the American Locomotive Company, New York, gives
the results that have been obtained in service with the Mikade
lecomotives built for the Chesapeake & Ohio. It is shown
that these engines save 14 per cent. of the coai on a ton-mile
basis as compared with consolidations. The dynamometer
record from a test with a train oi 7,590 tous is shown, and
the capacity of the engine on various grades is given in one
of the tables. These locomotives are of special interest, from
the fact that their success led to a number of later and equally
successfd designs which are now in service on other roads.
SPARK ARRESTER Burton W. Mudge & Company, Chicago,
I have issued a four-page leaflet illustrating and describing
the Mudge-Slater spark arrester or locomotive hox front end.
as it is sometimes called. This device was developed on the
Chicago & North Western, for the elimination of spark throwing
from locomotives. It takes the place of all of the usual front
end nettings and bafe plates; it is much more simple in its
constraction and is much easier maintained. It forms a seal
between the front end and the stack, permitting only those cinders
that will pass :rongh the meshes of the netting to escape. It
is installed on a large number of locomotives, and has not only
proved to be an efficient snark arrester, but also a fuel economizer.
it is especially desirable for locomotives traversing wooded
territories.
REVERSING MOTORS.-Bulletin No. A-4081 from the General
Electric Company. Schenectady, N. V., gives a discussion of the
advantages of, as well as a description of the apparatus required
in connection with the ase of reversing motors on planers and
slotters. This type of reversing motor application was illus-
trated in page 46 u the January issue of this journal. The bul-
letin, luw ever. gives more extensive illustrations and a more
complete description of the details. Bulletin A-4085 from the
sante company is devoted to a complete description of battery
charging motor-generator sets intended for use in connection
with charging storage batteries.
BALL BEARINGS ON MACHINE Toots-Reducing the friction of
a bearing not only reduces the less of power and the amount of
lubricant required, but what is even of more importance in the
case of a machine tool, it reduces the wear. Ball bearings largely
reduce friction and, when they themselves do not cause an added
scurce of trouble, the attendant advantages are very desirable.
As an example of what can be accomplished with their use on a
lathe there is quoted in a recent catalog from the Hess-Bright
Manufacturing Company, Front street and Erie avenue, Philadel-
phia. Ta, the case of a 11 in. Lodge & Shipley lathe used in regu-
lar daily service, which was equipped with ball bearings on the
spindle in 1905. This machine was part to work on alloy steel
of great toughness and after six years' use examination showed
the bearings to be in perfect ecudition and the lathe to have an
error of only .0008 in. These bearings had received no attention
during this time and were oiled but once a year. This catalog
also discusses the use of bearings for various parts of different
machine tools and illustrates suggested arrangements of the ball
races in the different applications.
LIQUOR ON PASSENGER TRAINS. The legislature of Indiana
has passed a law making it illegal for any person to drink in-
toxicating liquors on a passenger train or car, steam or elec-
tric, except in case of actual sickness of the person using the
stimulaut, and excepting also drinks taken in cars regularly
licensed to sell intoxicating liquors. The penalty for violation
of this law is from $5 to $25.
