UNITED STATES A R'NE LINDE, OF MACRORIE, SASKATCHEWAN, CANADA.

WRENCH.

v Specification of Letters Patent. Ptllted fhllg. 30, 1921.

Application led September 4, 1920. Serial No. 408,400.

To all whom t may concern Be it known that I, ARNE LTNDE, a citizen of the Dominion of Canada, residing at Macrorie, in the county of Moose Jaw and Province of Saskatchewan, have invented certain new and useful Improvements in Wrenches, of which the following is a specication. l l v This invention relates to wrenches and consists of a construction having a hollow handle with a movable head.

The object of my invention is to provide a wrench in which the head is so held in the handle that it can be positioned at different relative positions thereto so as to allow the head to be turned to various angular positions for turning nuts which are difficult for the ordinary wrench to get a holden.

A further object is to provide tension jaws which control the position of the head relatively to the handle.

A further object is to provide a means for releasing these jaws as may be desired.

A further object is to provide a locking means f or holding the head in fixed position in said handle.

With these'l and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be Vhereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.`

Figure 1 is a plan view of my invention with the head in locked position relatively to the handle.

Fig. 2 is a plan view of my invention the handleV being shown in section. i

Fig. 3 is a side view ofthe head, the handle being partly .broken away.

Fig. 4 is a plan view of my invention showing the head in bent position.

Referring to the drawings, like numerals designate like parts in the various drawings.

5 indicates a handle having a hollow Center 6 which hollow center forms an enlarged opening ormouth 7 at one end and an enlarged opening S at the opposite end. Positioned in theopening 7 are the jaws 9 and 1() on theirrespective pins 11 and 12. These jaws are tensioned apart at their inner end by a coil spring 14.

V17 which causes the outer end of the head to be tensioned in the direction of the arrow, Fig. 2, when thejaws 9 and 10 are released froni controlling the same. The inner end of thehead 15 is provided with notches on its opposite side adapted to coperate with the outer ends of thejaws 9 and 10 so as to hold thehead 15 in at least three different relative positions to the handle 5. It will be seen that the notches are so formed that the head can be turned opposite to the direction of the arrow and the outer ends of theaws 9 and 10 will engage in the next Arespective notch. lVhen it is desired to allow the head to turn in the direction of the arrow, arod 18, which passes through the hollow center 6, is pressed inwardly. This rod is provided with abutton 19 at its outer end and a bifurcatedend 20 at its inner end, which bifurcated end [its vover the outer sides of the inner end of theaws 9 and 10 so that when therod 18 is pressed inwardly the inner ends of thejaws 9 and 10 are pressed inwardly against the tension of the spring 14, but at the same time releasing the outer ends from the notches in thehead 15. The spring 17 then turns the head in the direction of the arrow, Fig. 2,

In some cases it will be found more satisfactory to have the head in fixed position to the handle, and to provide locking means for the head, l use a sliding member 22 which carries apin 23, which pin is adapted to engage in anotch 24 on the innerend vofthe head 15 when the head is in straight outward position to the handle 5. From the foregoing it is thought that the construction of my invention will be clearly understood, and, therefore, a more extended explanation has been omitted.

What I claim as new is: 1. A wrench consisting of a handle, a head pivotally mounted in one end of said handle, tension means holding said head at an angle to said handle, a means for locking said head at a different angle to said handle and a means for operating said locking means. 2. A wrench consisting of a handle, a

head pivotally mounted in one end of said handle, tension means holding said head at an angle to said handle, a means 'for loeling Said head at a different angle to said handle, a means for operating said looking` means and a means for looking said head in Straight outward position relative to said handle.

In testimony whereof I aliiX my signature in the presence of two Witnesses.

ARNE LINDE.
