that form of the invention shown in Fig. 6
of the drawings, these jaws are indicated by
the numerall 1a and are of such form that
the head may be employed in the manner of
e an alligator or pipe wrench. It will be un-
derstood, of course, that a number of the
heads 10 will be provided and that these
heads shall have jaws of various forms and
so spaced and shaped as to fit various sizes
:.o or pipes, nuts and other elements to be ro-
tated and that therefore, the two forms of
jaws shown in the drawings are to be con-
sidered merely as illustrative of the fact
that jaws of various kinds and sizes may be
employed in connection with one and the
same stock. The periphery of the head 10
is provided with a series of ratchet teeth 12
with which the tooth 9 of the pawl is de-
signed to coperate when the head has been
20 properly fitted between the cheek pieces 2.
By reference to the drawings and particu-
larly to Fig. 3 thereof, it will be observed
that -the opposite faces of the body 10 at
the inner periphery thereof are continuously
25 beveled as indicated at 13 and that each
face of the head is formed with a recess or
groove 14 which is radial to the axis of the
head. Rotatably disposed within the open-
ing in the head is a centering member in the
0 form of a circular body 15 of a diameter to
fit snugly and yet freely rotatably within
the said opening in the head and provided
at diametrically opposite points with
threaded openings or sockets 16 terminating
85 at their outer end in countersinks 17. After
the centering member has been disposed
within the opening in the head, screws 18
having beveled heads 19 are fitted into the
opposite ends of the openings 16 and the
40 beveled heads of these screws will project
slightly beyond the periphery of the said
centering member and engage the bevels 13
of the head 10 in the manner clearly shown
in Figs. 2 and 3 of the drawings. In this
45 manner, the centering member is rotatably
assembled with the head and prevented from
becoming displaced with relation to the open-
ing in the said head in which it is mounted.
Each face of the centering member 15 is
50 formed with a diametric groove 20 and
these grooves are designed in either one of
two positions of the centering member with
relation to the head 10 to register at their
ends with the grooves 14 in corresponding
55 faces of the said head, as for example, in
Fig. 2 of the drawings. The inner or op-
posed faces of the cheek pieces 2 are formed
each with a transversely extending rib 21.
These ribs extend parallel to each other and
60 are of a length substantially equal to the
lengths of the grooves 20 and the opposite
edges of each of the ribs 21 are preferably
beveled as are also the side walls of the
grooves 20 and the corresponding walls of
65 the grooves 14, It will now be understoodthat when it is desired to assemble the head
with the stock, it is only necessary to ro-
tate the centering member so as to bring
one or the other of the ends of the grooves
20 into registration with the inner ends of 7o
the grooves 14 as shown in Fig. 2 where-
upon the head is so positioned with rela-
tion to the stock, that the outer ends of the
grooves 14 will be presented to the outer
ends of the ribs 21. The head is then slid 75
inwardly toward the stock until the ribs
21 are received wholly within the grooves
20. The centering member will then be held
stationary or against rotation while the
head 10 itself may have back and forth mo- 8o
tion about the said member without, how-
ever, any likelihood of its becoming acci-
dentally displaced with relation to the cen-
tering member or to the stock. By revers-
ing-the above described operation and slid- 85
ing back the pawl 3, the head may be readily
disconnected from the stock and another
head substituted therefor. Obviously, the
wrench will be mounted in the same man-
ner as an ordinary ratchet wrench. go
When it is desired to employ the imple-
ment in the manner of a socket wrench, the
attachment shown in Fig. 7 may be as-
sembled with the nut to be turned and the
wrench applied to the said attachment in 95
the same manner that it would be applied
to the nut if the nut were .in such position
as to permit of the use of the wrench alone.
The said attachment comprises a body 22
which is exteriorly polygonal in form and 100
interiorly polygonal so as to fit the nut to
be turned and it is preferable that the body
be provided in each end with a socket 23
and that the two ends of the sockets be of
different sizes so that a single attachment 105
may be applied to two nuts of different
sizes.
Having thus described the invention, what
is claimed as new is:
1. In a wrench of the class described, a 110
stock provided with spaced cheek .pieces,
one of said cheek pieces being provided upon
its inner face with a rib, a head having, an
axial socket, a centering member rotatably
fitted within the said socket, the said mem- 115
ber and head being provided each with a
groove and the said grooves being designed
to register in. a predetermined relative po-
sition of the head. and centering member
whereby the head and centering member 120
may be slid into position between the cheek
pieces with the said rib passing through
the registering grooves and into the groove
in the said centering member, and pawl and
ratchet connection between the stock and 125
head, the said head being provided with
coacting jaws.
2. In a wrench of the class described, a
stock provided with spaced cheek pieces,
one of said cheek pieces being provided upon 130a
