GEORGE WASHINGTON BERGEN, OF BELMAR, NEW JERSEY.

FRICTION GRIP WRENCH.

Application filed November 30, 1923. Serial No. 677,775.

To all whom it may concern:

Be it known that I, GEORGE W. BERGEN,

a citizen of the United States, and a resident of Belmar, in the county of Monmouth 5 and State of New Jersey, have invented a new and Improved Friction Grip Wrench, of which the'following is a full, clear, and exact description.

This invention has relation to wrenches and has particular reference to a friction grip wrench which is particularly designed as a tool for facilitating the removal of headlight rims.

For one of its principal objects the invention contemplates a wrench of the character set forth which is readily adjustable to cooperate with headlight rims of various sizes.

The invention further contemplates a wrench provided with a manipulating handle for eflecting the contraction of the flexible embracing element about the rim or other article to be turned, which handle is provided with an arcuate arm for indirect engagement with the rim or article to be turned whereby to arrest the swinging movement of the handle after the desired contraction of the embracing element has been obtained.

Furthermore the invention contemplates an arm carried by the manipulating handle, the arc of which is adjustable to coincide with the periphery of the rim or other article with which the wrench is engaged.

As a still further object the invention contemplates a friction grip wrench of the character set forth which is so constructed as to prevent scratching or marring of the finish of the article with which it is engaged.

As a still further object the invention contemplates a friction grip wrench which is comparatively simple in its construction and mode of operation, which is inexpensive to manufacture and which is highly efiicient in its purpose.

With the above recited and other objects in View, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the drawings-- Figure 1 is a side View of a wrench constructed in accordance with the invention and illustrating the initial application of the wrench on a headlight rim.

Fig. 2 is a similar view illustrating the final gripping position of the wrench.

Fig. 3 is an edge view of the wrench in the position illustrated in Fig. 2.

Fig. 4 is a view similar to Fig. 2 illustrating a modified adaptation of the invention.

Referring to the drawingsdoy characters of reference, the wrench comprises a handle or lever having a laterally projecting arouate arm 11 at one end which is formed with a reversely curved toothed surface 12 at the juncture of the arm with the handle or lever. The handle or lever 10 adjacent its juncture with the arm is further provided with a bearing lug 13 through a bear ing opening 14 of which one leg 15 of a substantially U-shaped link 16 extends. The remaining leg 17 of the link has mounted thereon the looped terminal 18 of a flexible embracing member 19. A retaining strip or plate 20 is mounted over the free ends of the legs 15 and 17 and is secured in place by the washers and pins 21 and 22. The flexible embracing member 19 which preferably consists of a fabric strap is lined on its inner face for the major portion of its length with a strip of soft yieldable material 23.

In use and operation of the wrench the free end of the flexible embracing element 19 is inserted through the link to produce a loop in the element 19 with the yieldable lining 23 on the inner side of the loop. The loop thus formed is then arranged in embracing relation around the headlight rim A or other article to be turned by the wrench and the loop is contracted by exerting a pull on the free end of the flexible element 19 as illustrated in Fig. 1. The toothed reversely curved portion 12 at the juncture of the handle and arm 10 and 11 is then engaged with the outer surface of the looped flexible element and by swinging the handle 10 in the direction indicated by the arrow in Fig. 1 a further contraction and frictional gripping of the looped portion of the element 19 will be efiected until the arcuate arm 11 finally engages with the loop and indirectly with the periphery of the rim A which arrests further swinging movement of the handle 10. Further'pressure exerted on the handle 10 will thus effeet a relative turning and unscrewing of the rim A with respect to the body of the headlight B. It will be noted that the yieldable lining material 23 prevents marring or scratching of the finish of the rim, while the device efiectually serves to remove the rim A from the body B.

In the modified form or adaptation of the invention illustrated in Fig. 4 the handle or lever 25 has secured to one end a laterally projecting curved or arcuate arm 26. which is resilient and flexible to a suitable degree and the handle or lever is provided with a reversely curved toothed portion 27. A flexible embracing element 28 is carried by a link 29 which is pivotally mounted'in the bearingear 30 adjacent the toothed end of the handle or lever. The handle adjacent the toothed end is further provided with a rigid arm 81 which pivotally carries as at 32 at its free end an element 33 having ofl'set terminals 34. In practice the ofi'set terminals 34 are designed to engage at longitudinally spaced points the flexible' and resilient arm 26 to cause'the same to coincide with the arc of the periphery of the headlight rim A whereby the arm 26 will coincide with the periphery of rims of various diameters. The general operation of the device illustrated in Fig. 4 is similar to that of the first form illustrated in Figs. 1 to 3 inclusive.

I claim:

1. A friction grip wrench including a flexible element adapted to be arranged in looped form for embracing the article to be turned, a handle having linked connection with one end of said element and formed with a gripping face engageable with the opposite free end of the flexible element for contracting the looped portion about the article upon swinging of said handle in one-direction, said means being adaptable to the curvature of the periphery or" the loop.

2. A friction grip wrench including a flexible element adapted to be arranged in looped form for embracing the article to be turned, a handle having linked connection with one end- 01 said element and formed with a gripping race engageable with the opposite free end of the flexible element for contracting the looped portion about the article upon swinging of said handle in onedirection, said means comprising a normally curred resilient arm'carried by the handle, and a member pivotally carried by the handle having 'ottsets thereon spaced longitudinally of and contacting with the arm for flexing the same to cause it to coincide with the curvature of the periphery of the loop.

A friction grip wrench including a handle having a laterally curved toothed end and an arcuate terminal at said end, alink pivoted to the handle adjacent said end, and a flexible work embracing member connected at one end to the link and having its free end trained through said link to produce an embracing loop for encircling the articles to be turned, the said toothed end adapted for engagement with the flexible embracing element for contracting the looped portion upon swinging of the handle in one direction, and the said curved terminal constituting means for arresting the swinging movement the handle upon engagement with the looped portion when engaged with the article to be turned.

GEORGE WASHlllGTfill BERGEN.
