CHARLES HENRY PARKER, OF KANSAS CITY, MISSOURI.

WRENCH.

To all whom it may concern:

Be it known that I, CHARLES H. PARKER, a citizen'of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in renches, of which the following is a specification.

My invention relates to a 'wrench which may be easily and quickly adjusted to grip different sizes of work and which is provided with a plurality of jaws disposed at different angles with relation to each other. An important object of this invention is to provide a device ofthe above character, which is simple in construction, cheap to manufacture and a time saver to the user.

. A further object of this invention is to provide a wrench including ainovable jaw "having both ends thereof adapted to grip .the work, such ends being so constructed that by their em loyment the work may be engaged from di erent angles.

A further object of this invention is to provide a wrench of the above character, which is formed of few and simple parts that may be removed for the purpose of cleaning or repair.

Other objects and advantagesot' this. in-

vention will be apparent during the course,

of the following descriptionl In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side view of the wrench, parts thereof being shown in section',-and, Fig. 2 is a plan view of the same.

In the drawings wherein is illustrated a preferred embodiment of my invention, a wrench is shown comprising a handle 1, through one end of which is formed an opening 2 for the reception of a transverse in 3 referabl havin its ends rounded as shown. This pin is held against movement within the opening 2 by a clamping screw 4. Upon the opposite end of the handle 1 is formed a head 5, portions of which serve as stationary jaws One of these portions is designated by the numeral 6 and is cut out to receive a removable corrugated plate 7, which is removably mounted thereon and rigidly connected therewith by a screw 8.

. The portion 6. extends longitudinally of and parallel with the head 5 and forms the forward end portion thereof. The other portion of the head is designated by the nu- Specification of Letters Patent.

is a movable head 10,.the forward end por-- tion 11 of which serves as a jaw to cotiperat with the plate 7 The rear end of the head 10 is beveled, as shown at 12 so that its wall is parallel with the plate 8 and serves as a movable jaw for cooperation therewith. The head 10 has screw-threaded engagement, with a pair of spaced parallelguide pins 13, which are slidably mounted within transverse openings 14 formed through the head 5; The head 5 is provided centrally thereof with a rectangular opening 15, for the reception of an operating nut 16 having its periphery corrugated or milled, as shown. The operating nut. 16 extends beyond the sides of the head 5, as clearly illustrated in Fig. 2. This operating nut is screw threaded internally for engagement with a screw-threaded pin 17, which operates through alined openings 18 formed transversely throughthe head 5. This screwthreaded pin has one end thereof disposed and the plate 7 or the same may be gripped between the jaw 12 and the plate 8', depending upon the location and the angle at which the .wrench can be more conveniently operated. The wrench is formed of few and simple parts, which may be removed or separated from the others for the purpose of repair or cleaning.

I wish it understood that the form of my invention herewith shown and described is to be taken a preferred example of the same, and that certain changes in the shape, size and arrangements of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claim.

Having thus described my invention, I claim A wrench comprising a handle upon onetending substantially parallel with the handle and a laterally inclined portion disposed at the inner end of the body portion, said body portion carrying upon its inner longitudinal face a serrated plate, the'in-' cline d portion carrying a serrated plate, a second head disposed near the body portion of the first named head and extending in parallel relation thereto, the second head having its inner end beveled to cooperate with the inclined portion of the first named head, pinsrigidly connected with the sec- 'ond named head and operating through openings in the first named head, a screwthreaded pin connected with the second 15 named head and operating through an opening formed in the firstnained head, and an operating nut disposed upon the screw threaded pin and operating in an opening formed in the body portion of the first 20
