TOOL.

Application filed tlctober 9, 1922. Serial No. 593,347.

and State of Pennsylvania, have invented certain new and useful Improvements in a Tool; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in m the art to which it appertains to make and use the same.

This invention relates broadly to an improved tool and has more particular reference to a device of this class which is cspecially, but not necessarily, designed for applying and removing headlight lens clamping rims.

The principal object of the invention is to generally improve upon tools of this class by providing one of comparative simplicity and durability which is practical in use, easy to manipulate, adjustable for use in connection with different diameters of clamping rims and inexpensive to both the manufacturer and the user.

More specifically speaking, it isanother object of the invention to provide a tool of this class which simplycomprises a resilient band which is adapted to surround the 0 clamping rim, one end of this band being bent upon itself and against the body portion of the band and this portion and bent portion being slotted and the last-named portion being corrugated to provide spaced bearings on opposite sides of the slot in which the removable and adjustable pivot pins carried by the operating lever are journaled.

Other objects and advanta 'es of the mvention will be apparent during the course of the following description.

In the accompanying drawings forming a. part of this specification and .in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a front elevational view. of an automobile headlight showing the tool In position on the lens clamping rim,

Fig. 2 is a side elevation thereof,

Fi 3 is a top plan view of the band laid out at,

Fig. 4 is an enlarged detail perspective view of the unique end-construction of the band, and

Fig. 5 is a detail perspective view of contracting lever.

the

In the drawings, the letter B designates the body of a conventional type of headlight lens and the letter R represents a removable clampingrim for the transparent lens I. Ordinarily, this clamping rim is connected With the body through the medium of pins and slots formed in thebody and rim respeotively and after the rim has been in place some time, both it and the body become rusted to an extent to render easy removal of the rim by hand practically impossible. Hence, theneed for a practical tool for both removing and applying the rim is essential in order to permit the latter to be removed without damaging it or the lens.

Although this improved tool could be of some'other construction, it preferably comprises a resilient comparatively narrow metal band 1 which is intended to encircle the clamping rim R in the manner shown. As is obvious, the free ends of the band are adapted to be brought into overlapping relation to contract'the band sufficiently to obtain the necessary grip for removing a rim which has become stuck. A novel arrangement is employed for permitting this contracting of the band. As shown, one end of the band is bent upon itself as indicated at 2 and is then bent back and against the body portion of the band as at 3. This bent portion and body ort-ion against which it is brought to bear is formed with an elongated slot 4 which opens through the bend 2. The bent end of the band is corrugated as shown to provide a plurality of closely spaced and oppositely disposed bearings 5. In addition to these bearings 5, two or more other bearings 6 are employed, the last named bearings being secured to the opposite end of the band. A. lever 7 is pivotally connected with the last named end of the band and extends through the aforesaid slot, having connec tion with this slotted end of the band so that when it'is properly manipulated, it will contract the band sufiiciently to obtain the desired grip on the clampin rim. he better seen in Fig. 5, this lever 15 preferably construeted from a cylindrical rod which has one end flattened as at 8 and provided with a plurality of closely spaced apertures 9 through which removable pivot pins or bolts 10 pass. Due to the fact that 'thereare several apertures formed in the lever. it is obvious that the pivot pins can be adjusted to vary the leverage. Furthermore, due to lid . l "1 1 P, the fact that the slotted end of the band is equipped with a plurality of closely spaced bearings, it will be seen that the upper pivot pins can be arranged in the desired bearin s for permitting the band to work effective y on difij'erent diameters of clamping rims.

In some instances, lens clamping rims are equipped on that portion of the rim which the band surrounds, with projections and in order to prevent these projections from interfering with the operation of the im proved tool, cumferentially spaced openings 11 through which these projections may extend. So that the extreme tightening of the band against the rim will not damage or remove the paint from the latter, a felt lining or the like 12 is secured in any suitable way to the inner surface of the band to directly contact the clamping rim. This felt will assist in preventing slipping of the band when in operation. Furthermore, a handle 13 ma be employed in practice and this handle Wlll be secured to the band at a point substantially diametrically opposite the overlapped ends. lVith the use of this handle, easy matterto rotate the rim on the body of the headlight to permit removal of the former. v

in use, the band is placed about the clamping rim as shown on the drawings and the upper pivot pin of the lever is placed in the proper bearings 5 according to the diameter of the rim. Then, the lever s grasped and rocked about the lower pivot in a direction to draw the ends of the band into overlapping relation, thus obtaining the desired grip. Finally, by still holding the lever and grasping the handle 13, the clamping rim can be rotated in the desired direction to disengage the rim slots from the projections on the headlight body, so as to permit removal ofthe rim for obtaining access to the interior of the body or for replacing the broken lens for adjusting the bulb or the band is equipped with cirit will be an aeeenee of the invention. Therefore, a more lengthy;=

and detailed description is deemed unnecessary.

Since probably the best results may be obtained with the construction and arrange ment herein shown and described, this is taken as the preferredembodiment of the invention. However, I wish it to be understood that minor changes coming within the scope of the invention as claimed may be resorted to if desired.

I claim:

A tool for removing and applying headlight lens-clamping rims comprising a resilient band to surround the rim, one end of said band being bent upon itself and back against the body portion, said portion and the exterior of that v bent end being formed with a slot and the bent end being formed with transverse corrugations providing hearings on opposite sides of the slot, additional bearings on the opposite end of the band, a lining on the inner face of the band to engage the aforesaid rim, a hand-operated lever for contracting the band having journals received in said bearings, and a hand-grip secured to the band at a point substantially diametrically opposite the lever.

, In testimony whereof I have hereunto set my hand. p
