ATTORNEY WITNESSz UNITED STATES PATENT OFFICE.
FREDERICK Ii. ALLEN, 0F BOISE, IDAHO.
WRENCH.
Specification of Let-ters Patent.
Patented Mar. 14, 1922.
Application led April 19, 1921 Serial No. 462,640.
"To all whom t may concern Be it known that I, FREDERXCK L. ALLEN, a citizen of the United States, residing at Boise in the county of Ada and State of Idaho, have invented new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to wrenches, particularly to those of the class commonly known as Stillson wrenches, and has for its object the provision of a wrench of this type 4 embodying various advantageous features in point of construction, combination and arrangement of parts.
An important object is the provision of a wrench of this character which is provided with spring means for frictionally engaging an operating nut so that the nut may not be moved too easily. An additional'object is the provision of a wrench of this character which will be simple .and inexpensive in manufacture, highly eliicient in use, durable in service and a general improvementin the art.
With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described, and claimed, and illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view of the wrench.
Figure 2 is a longitudinal section therethrough.
Referring more particularly to the drawings the numeral 10 designates the handle of my wrench which has its outer edge enlarged as shown and the end rounded toward the horizontal wall of the enlargement as indicated by the numeral 11, this rounded edge being formed with a series of relatively ne teeth 12. The numeral 13 designates a carriage which has one of its ends provided with a depending portion 14 formed with a tion of a milled actuating nut 21 which has its'bore formed with threads coacting with the threads on the shank of the movable Jaw.
Arranged upon the upper face oit the handle 10 to the rear oit the carriage 13 is a second `lat spring 22 which has its end arranged within the slot or passage 15 contacting with the upper wall thereof. The springs 16 and 22 sustain the handle 10 longitudinally of the depending portion 14 of the carriage as will be readily understoodA The vforward and lower face of the carriage is provided with a slot 25 which is adapted to receive a centrally arranged lug 26 provided upon the end 11 of the handle, while passing through the walls provided by the slot 25 is a pivot member 27 which connects the headed end 11 of the handle with the carriage. The portions 24 and 11 provide the stationary jaw for the wrench. It will be noted that by providing the stationary jaw with the two heads 24C and 11 respectively, that when an article is received between the movable jaw and the stationary jaw, a swinging of the handle in the direction ofthe arrow will cause a pipe or other article to be gripped` indicated by the numeral 28, to be tightly compressed against the rounded edge 24 and the rounded end 11 of the jaw while the said jaw may be readily swung in a reverse direction to the arrow in ordery to obtain a tighter grip upon the pipe or other article or to provide a ratchet movement of the wrench upon the pipe.
It is preferable that the free end of the shank of the movable aw be formed with a knurled or milled depressed portion 29 engageable by the thumb of an operator whereby the movable jawmay be swung into its initial position when it is desired to engage the wrench upon a pipe or other article to be turned.
I also prefer to make use of a leaf spring 30 which has one end secured within the interior of the carriage 13 and which has its other end bearing upon the actuating nut. It will be observed that the interior of the carriage is hollowed out for the proper accommodation of the spring.
From the foregoing description and a study of the drawings it will be apparent that I have thus provided an extremely simple and inexpensive wrench which will be very highly ellicient for turning objects, especially those which are round or otherwise sult in casual displacement of the parts or not easily handled by means of ordinary wrenches. It is likewise to be observed that the provision or' the auxiliary spring` which bea-rsagainst the operating nut prevents any undue looseness in this nut which mightA reloosening or tightening of the Wrench when it is undesired.
While l have shown and described the preferred embodiment of the invention, it is of course to be readily understood that I`reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the in-A vention nor the scope of the subjoined claims. Having thus described my invention I claim: l
l; In a wrench of the character described,-
` a handle having one of its ends enlarged and the outer edge of said enlargement rounded, a carriage having a passage for the reception of the handle, the handle being provided the threads of the shank vor the movable jaw, the outer face` of the carriage having its Y lower portion rounded and being provided with a slot, the enlarged end of the handle having a lug disposed withinV the slot and v which is pivotally connected to the carriage,
mi Y i 1,409,811
and the saidl roundedlower portion of the carriage and the enlarged outer end of the handle constituting a stationary jaw for the wrench.
2. In a wrench of the character described, a handle having one of its ends enlarged and theouteredge of said enlargement rounded, a carriage having a `passage for the reception 'or' the handle, the handle being provided with oppositely disposed springs which engage with both the upper and lower walls of the passage, the carriage havingthe upper portion provided with a second passage for the reception orn the shank of a movable j aw, the opposite longitudinaledges of the said jaw being notchedto provide teeth, the said carriage having a trans-verse opening which intersects the upper passage' for the reception oan actuating nut which engages with the threads of the shank of the `movable jaw, the outer ace'of the carriage having its' lower portion roundedand being provided'with a slot, theenlarged end of the handle having aV lug disposed within'the slot and'which 'is pivotally connected tothe carriage, the said rounded lower portion of the carriage andthe enlarged outer end of the handle constituting a stationary jaw'for the wrench, the interiorlofthe said carriage being partially hollowedout, and a leaf spring securedwithin said hollow'ed out portion and having its free end bearing against said actuating nut whereby to Afriction'ally' hold the same and prevent imduly vfree movement ofthe' wrench thereof.y s ,I
