JOSEPH NIELANIDER, 0F KOKOMO, INDIANA.
WRENCH;
To all whom it may concern:
Be it known that I, JOSEPH NIELANDER, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates towrenches of the sliding jaw type which are capable of use either as a nut or pipe wrench.
The primary object of the invention is to provide a wrench which may be easily and quickly adjusted for use and when so adjusted will be securely held in position, the arrangement of the various elements being such as to more tightly lock them when strain on the jaws of the wrench is greatest.
Another object is to provide a cheap simple and inexpensive wrench permitting its sale at a normal cost, and reducing liability to breakage of the various parts used in its construction.
The invention therefore consists of a wrench having a novel form of adjusting a locking means embodying a pivoted shaft carried by the movable jaw and having mounted thereon a freely rotatable locking member, the opposite end of the shaft being engaged by an operating dog also pivoted to the movable jaw, so that the said locking member may be moved into and out of engagement with a rack formed upon the shank of the wrench.
The invention further consists of the following novel combination and arrangement of parts, hereinafter more fully described and illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation of a wrench embodying the invention, the movable jaw being shown locked to the shank.
Fig. 2 is a view similar to Fig. 1 with the locking member disengaged from the shank and a portion of the movable jaw broken away to more clearly show the manner in which the locking member is secured thereto.
Fig. "3 is a transverse sectional view on the line 3-3 of Fig. 1.
Fig. 4 is a detailed perspective view of the movable jaw detached from the wrench.
Fig. 5 is a similar view of the pivoted shaft.
Fig. 6 is a detailed perspective view of the operating dog.
Fig. 7 is a view similar to Fig. 1 showing a modified form of wrench.

wrenchshown in Fig. and
Fig. 9 is a detailed perspective view of the sleeve within which the movable jaw is adjusted in the modified form shown in Figs. 7 and 8. i Y 1 Referring in detail to the drawings and more especially to Figs. 1 to 6 inclusive, the improved wrench comprises a shank 10 of preferably rectangular cross section, which has secured orformed uponv one end a stationary jaw 11 and upon itsoppositeend a Fig. 8 is a view similar to Fig. 2 of the handle 12, the latter being secured thereon by any desired means. j
Mounted for movement longitudinally of the shank 10 is a movable jaw. 13, the said jaw carryinga sleeve 1 1, through which the shank 10' is designed to pass. Mounted within the movable jaw 13 in a recess 15 upon a pivot pin 16, is a shaft 17. This shaft is formed with a rectangular head 18, having an opening 19 therethrough for the passage of the pin 16. The head 18 is so positioned within the recess 15 as to provide a space between the end of the head and the end wall of the recess: 15 and secured to this head is one end of a spring 20', the opposite end of the spring bearing against the said end wall in a manner to normally force the free end of the shaft 17 toward the shank of the wrench.
The free end of the shaft 17 is reduced as shown at 21, this reduced end being received within a notch 22 formed in one end of an operating dog 23, which latter is pivoted between ears 9A carried by the movable jaw, the pin upon which the dog is pivoted being shown at 25. The end of the dog opposite the notch 22 is formed with a finger piece 26, by means of which the dog is manipulated to move the shaft 17 away from and toward the shank 10.
Mounted to freely rotate upon the shaft 17, between the shoulder 27 formed at the juncture of the said shaft with the head 18, is a locking member 28, which consists of a sleeve formed with a screw thread 29, which are adapted to engage the teeth of a rack 30 provided upon one edge of the shank 10, for the purpose of final adjustment of the jaw 13 and for locking the said jaw in its adjusted position.
To operate the wrench the finger piece 26 ment with the rack 30, permitting the movable jaw to freely slide along the shank.
' is adapted to slide through a sleeve 33, se-
cured as shown at 34: to the stationary jaw 35. Pivoted within a recess 36 provided in the sleeve 33 is a shaft 37, similar in construction to the shaft 17 and mounted upon this shaft for free rotation is a sleeve 38, which is adapted to engage the rack 39 formed on the shank 32. An operating dog 40 also similar in construction to the dog 23 is pivoted within ears ell carried by the sleeve 3 3,the adjustinent of the wrench being the same as in the form previously described. The jaws 31 and 35 have their opposed faces serrated as shown at 42 in order to provide a grip upon a pipe or other cylindrical object.
'Various changes in the form, proportion and minor details of construction may be made without departing from the spirit or sacrificing any of the advantages of the invention.
Having described the invention what is claimed is:
A wrench embodying a shank, a stationary jaw thereon, a toothed rack formed on said shank, a sleeved jaw mounted for movement along said shank, a shaft having one end pivotally mounted in the sleeve of the movable jaw, a locking member rotatably mounted on said shaft for engagement with the toothed rack, an operating dog also pivotally mounted in the sleeve of the movable jaw and means engageable with the pivot end of shaft, whereby the locking member will be yieldingly held in alocked or unlocked position.
In testimony whereof I afiiX my signature.
JOSEPH NIELANDER.
