American Tool Works
This is a 16 by 78 inch toolroom
lathe. The power clutch is engaged by a lever near the headstock or the
one on the apron (These are not yet installed on this machine). It has
a ball bearing taper attachment. It has the power train for
a relieving attachment, and you might be able to see the short shaft
sticking out just above the feed gear box which is connected to
the relieving attachment. The large and the small levers on the front
of the headstock change the spindle speed. The large one has six
positions. The small lever just above it changes through three speed
ranges. This gives a total of 18 spindle speeds. (Nine and 21
speeds were also available.) A small
lever on the feed speed gear box selects between lead screw and power
feed. There is a lever on the apron to change lead screw
direction . One of the feed clutches in the apron is a friction
cone and the other is a splined disk.
American Pacemaker Lathe - 1943
This has a twelve inch
mounted and the spindle nose is a D1-6. According to the General
Electric tag that was still on this machine, the original motor was a
25 cps induction motor. The dealer tag that you can see here on
the front says that this machine was originally sold by a dealer
in Baltimore, Maryland. The lathe was made in 1943.
A short history of The American Tool Works
Tool Works was the successor to Lodge, Davis & Co. started in
1876. [My note: In one advertisement
that I have found, Lodge, Davis & Co. claims to be the
'Successors to Lodge, Barker & Co."] It then became
Lodge and Davis Machine Tool Co. In
1892 Lodge sold his interest to Thomas Egan of Fay and Egan Co. and it
became Davis and Egan. In 1898 it was bought by Franklin
Alter and A. B. Voories and named American Tool Works. [My note: According to a patent application
that I read, ATW was incorporated in West Virginia.] It
purchased in 1966 by Curtis Manufacturing Co. of Cleveland but it kept
its name. In 1968 it was purchased by Wyle Laboratories. In
1973 it was sold to Fischer Industries and it 1980 it was sold to
White Consolidated Industries, Cleveland. (L.B.)
following was supplied by Annette Stewart at Bourn-Koch: "White
Consolidated Industries owned The Bullard Co., American Tool Works and
White-Sundstrand Machine Tool. All of these divisions were
consolidated in 1987 in one plant. When Electrolux merged with
White Consolidated Industries, the decision was made that the focus
would only be on the appliance industry. White Consolidated
Industries sold the company and it eventually became DeVlieg Bullard
Services Group. In September 2004, Bourn & Koch bought the
assets of DeVlieg Bullard Services Group."
This lathe was designed, I am told, by William G.
Hoelscher, engineer at American Tool Works. I cannot find out any
information about this man, other then that Linda Bailey tells me that
he is listed in the Cleveland city directory as the chief engineer at
American Tool Works at about the time this lathe was made. Eleven of
the twelve patents declared on this lathe are attributed to William G.
Hoelscher. Albert E. Robinson is given as a co-inventor on some of the
patents. Patent 2,173,557 is for the ball bearing taper
attachment. It was granted September 19, 1939. The patent has very good
drawings and a description of this attachment. The patent
states,"William G. Hoelscher, Norwood, Ohio, assignor to the American
Tool Works Company, Cincinnati, Ohio, an Ohio Corporation."
Other patents are: 1,926,996 for the rapid traverse (not an option on
this particular lathe.) 1,926,998 for the lubrication of the headstock
transmission. 1,966,409 for the tailstock.
