JOHN G. WRIGHT, OF TYLER, TEXAS.
WRENCH.Specification of Letters Patent. ' Patented Jan. 4;1916.
Application filed May 25, 1915. Serial No. 30,3#9.To arc whom it may concern:
Be'. it known that I, JOHN G. WRIGHT, a
citizen -of the IUnited States, residing at
Tyler, in the county of Smith and State of
5 Texas, have invented certain new and' useful
Improvements in Wrenches; and I do here-
by declare the following to be a full, clear,
and exact description of the invention, such
as' will enable others skilled in the art to
10 which it appertains to make and use the'
same. .
This invention relates to wrenches and
more -.particularly to that type generally
known as the spanner wrench.
15 The invention has for its primary object
to provide an improved spanner wrench in-
cluding' means for reliably retaining the
wrench head in proper position with rela-
tion to the object to be rotated.
20 With this and other objects in view, th
invention consists in the novel construction,
arrangement and formation of parts as 'will
be hereinafter specifically described, claimed
and illustrated in the accompanying draw-
25 ing, in which:
Figure 1 represents a fragmental perspec-
tive view of the wrench complete. Fig.' .2
represents 'a side elevation of the improved
wrench, partly in section, and applied to use.
30 Fig. 3 represents a side elevation of the
wrench, partly broken. away, illustrating the
same applied to use. Fig. 4 represents.a per-
spective view of the holder removed. "Fig.
5 represents a fragmental perspective view
35 of the annular head and adjacent portion
of the handle of the wrench. Fig. 6 repre-
.sents' a fragmental sectional view on the line.
6-6 of Fig. 2. Fig. 7 represents a frag-
mental perspective view of the centering ele-
40 ment for the wrench removed..
Referring to the drawing in detail, where-
in similar reference numerals designate cor-'
responding parts throughout the several
views, the numeral 5 indicates the handle or
45 shank of the wrench, which is formed at one
end with an enlarged annular head 6 formed
at one edge 'with an.inwardly directed an-
nular flange 8. The side face of the annular
head 6 opposite the flange. 8 is formed with
50 a plurality of axially projecting ribs or
wings 7. The end of the wrench handle 5
opposite the head 6 is formed .with 'a lateral,
enlargement or head.7a.
A holder designated generally: by the nu-"
55 meral~9 includes a body plate 10, preferably'
of circular formation and provided with. aradial recess 11 and a. semicircular laterally
projecting flange 12, which latter is pro-
.vided with a semicircular extension 12a ly-
ing in a plane parallel to the body plate 10.60
and adapted to coperate therewith. in hold-
ing the wrench head 6 in position upon the
object to' be rotated, as will hereinafter ap-
pear.,
SA' centering element 13 is provided with a 65
cylindrical shank' adapted to be rotatably
mounted within the annular head 6 and a
flange 14 adjacent that end adapted to en-
gage the flange 8 of the head 6 to limit the
outward movement of the shank 13 with re- 70
lation to the head 6, in one direction. The
opposite ends 15 of the shank are preferably
of polygonal formation, whereby the center-
'ing element may be used for removing
washer nuts. 75
The wrench is especially designed for use
in removing -annular or washer nuts 16,
which are often..used for holding gage
glasses 19 . of sight feed oiling systems.
The glass 19. is retained in position in the 80
holder 16 by the washer nut. 18 and the
holder 16 is formed at its outer.edge with
a plurality of spaced recesses for the re-
ception of the lugs or wings 7 of the wrench .
head." The holder 16 is further provided 85
with an annular flange 17. In use, the ribs
.or wings 7 of the wrench head 6 are en-
gaged within the recesses in the outer
flanged end'of the holder 16, and one end
of the 'centering element 13 is engaged 90
within the polygonal bore of the washer
nut 18 and the flange 14 thereof is seated
within the annular head 6.and engaged with
the flange 8 thereof. The wrench holder '9
is subsequently engaged .over the flange 17 95
of the holder 16 and the head 6 of the
wrench as clearly illustrated in Figs. 1 and
2, thus .securing the wrench head against
lateral removal from the holder 16 and in-
suring positive gripping action of the ribs 100
or wings 7. The washer nut 18 may be
conveniently removed from within the
holder 16 .by engaging the laterally pro-
jecting head 7a . of the wrench handle 5.
therein and rotating the wrench in the 105
proper direction.
What I claim is:
.1. In combination, a wrench including a
handle, a head at one end of said handle,
axially projecting ribs or wings on said 110
head, and means for securing said head in
position upon an object to be rotated.1,167,242. -
