The following
are screwdriver examples which I would like to purchase or borrow for
study
and photographing:
Forest City
Screwdriver
Company / PAT APRIL 16, 1895: This sprial/ratchet
screwdriver
looks very similar to the basic NORTH BROTHERS MANUFACTURING CO.
(YANKEE)
No. 30 (Handle is different shape, has two shifters on opposite
sides
of barrel, chuck is different)
Forest City Screwdriver Company: This
automatic drill probably looks very similar to the NORTH BROTHERS
MANUFACTURING
CO. (YANKEE) No. 40
S. F.
BOWSER
& .
/ PAT. APPD. / FT. WAYNE, IND.: There are four different models
which bear inscriptions similar to this. I am particularly interested
the
model which has a single spiral (RH only).
EUREKA
IMPROVED
/ PAT. MAR. 4 - 1890 / DECATUR COFFIN CO. / DECATUR IL.: This is
similar to the other Decatur Coffin Co. screwdrivers but utilizes a
socket/chuck
for interchangeable screwdriver tips.
H. MUELLER
MFG.
CO.
/ Decatur, Ill. / PAT. . JULY 30, 1889: Most H. Mueller
spiral
screwdrivers which you will see follow closely the basic conventional
patterns
of other makers and do not resemble the patent illustration at
all.
This illustration is of an earlier model in the style of an
Archimedian
drill which does resemble the patent (exposed shaft with sliding handle
which houses the clutch mechanism).
THE L. S.
STARRETT CO.
/ ATHOL, MASS. U.S.A./ NO. 801 / PAT. APPLIED FOR: There
are two models of this screwdriver - with a return spring and without a
return spring.
PAT APR 16-1889 / PAT APP'D FOR: This
may be
the only marking or may have other markings related to Gilbert T.
Sutterly,
Philadelphia.
PAT APR 16-1889 / PAT APP'D FOR: This
is another
form of the Sutterly patent above. This may be
the
only marking or may have other markings related to Gilbert T. Sutterly,
Philadelphia.
UNIVERSAL TOOL CO. / GRAND RAPIDS, MICH.
/
UTCO. / PATD.
DEC. 13, 1892 / PAT APD FOR.
