CHARLES A. SHORT, OF MANILA, PHILIPPINE ISLANDS.
WRENCH.
Application filed October 8, 1921.
T 0 all w 7mm it may concern Be it known that I, CHARLEsA. SHORT, a citizen of the United States, and a resident of Manila, in the Philippine Islands, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to wrenches of the self adjusting type.
An important object is to provide a wrench having novel means whereby the jaws are securely engaged with the object to be rotaed as the handle is operated Further the invention aims to provide a wrench having novel means whereby the jaws are released from gripping engagement with the object when the handle is returned to its operative position.
A further object is to provide a wrench which is efficient in use cheap to manufacture, and 01 highly simplified construction.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawing forming a part of this application and. in which like numerals are employed to designate like parts throughout the same,-
Figure 1 is a side elevation of the improved wrench, parts being broken away;
Fig. 2 is a plan view of the improved wrench, parts being shown in section;
Fig. is a perspective of a jaw embodied in the invention;
Fig. 4'- is a detailed sectional view through the wrench, the view illustrating the guiding means for the shank or rack of the movable jaw; and b Fig. 5 is a vertical transverse sectional view taken on line 5-5 of Fig. 3.
In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 designates a handle having its forward portion reduced as indicated at 6 to provide a pair of shoulders 7. The forward reduced portion (3 of the handle is formed with a gear segment 8 which describes the major part of a circle and which meshes with a pinion 9. is illustrated in Figure 2 the pinion 9 is rotatably supported by means of a pivot pin 10 extended through the spaced parallel rear-hardly extending arms 11 of a jaw 12. The spaced parallel side arms 11 are also Serial No. 506,323.
provided with a pivot pin 14 extended through the gear segment 8 whereby the jaw 12 is pivotally connected to the handle.
The pinion is in mesh with a rack 16 formed along the rear longitudinal edge of a shank 17 extended at right angles from a movable jaw 18. It will be seen that when the rear portion of the handle 5 is moved downwardly the pinion 9 will be rotated in a clockwise direction for moving the rack 16 longitudinally. When the rack 16 and consequently the shank 17 are moved longitudinally by the downward movement of the handle the jaw 18 is moved in the direction of the jaw 12 thereby firmly gripping an.
object such as a pipe which may be arranged between the jaws. As the downward movement of the handle continues the jaws 12 and 18 are more firmly gripped with the pipe.
As illustrated in Figures 1 and 3 the jaw 12 is provided rearwardly of its teeth with oppositely arranged projections 22 which are grooved on their inner sides to slidably receive the shank 17 whereby to guide the shank 17 in its longitudinal movement. The arms 11 are also provided with pairs of laterally projecting ears 23 which contact with the sides of the shank 17 and are connected by cross strips 24. The cross strips 24 are arranged at the edges of the teeth 16 and cooperate with the ears and the projections 22 in guiding the shank 17 in its longitudinal movement.
I claim A wrench comprising a handle having its forward portion reduced and formed with a gear segment, a jaw having a pair of spaced parallel arms overlapping said gear segment and pivoted to the same, a movable jaw having a rack slidable between said arms, said first named jaw being provided with oppositely projecting extensions having grooves receiving said rack, whereby to guide the rack, pairs of spaced ears projecting from opposite edges of said arms and having cross pieces engaging said rack at points spaced from said arms whereby to cooperate with said grooved extension in guiding said rack, and a single pinion mounted between said arms and directly engaged with said rack and said segment.
CHARLES A. SHORT.
