ELECTRIC LIGHT BULB WRENCH Filed May 19, 1952 IN VEN TOR.
figul S-DGJZLBLS Patented June 22, 1954 UNITED STATES PATENT OFFICE ELECTRIC LIGHT BULB WRENCH Paul S. Daniels, Rocky, Okla. Application May 19, 1952, Serial No. 288,664 8 Claims- (Cl. 294-20) My invention relates to bulb wrenches, that is devices used in changing electric light bulbs.
One object of my invention is to provide-an improved bulb wrench which is simple and rugged and which may be made cheaply.
Another object is to provide a bulb wrench which may be used to remove or replace bulbs of various sizes without adjustment.
Another object is to provide a bulb wrench which will grasp a bulb resiliently both in compression and in torsion.
For a more complete understanding of the nature and scope of my invention reference may be had to the description and drawings in which;
Figure 1 is a view in elevation, partly broken away and in section, of an embodiment of my invention, illustrating how it will engage bulbs of large andsmall sizes;
Figure 2 is a section taken on line 2-2 of Figure l; and
Figure 3 is an exploded view of the principal parts of the device shown in Figure 1.
Throughout the description and the figures of the drawing like reference numeralsrefer to similar parts.
Referring to the drawing, one embodiment of my invention is shown, comprising'a pole I on the end Id of which there is mounted a resilient cap 2 through the end .3 of which extend a plurality of elongated bulb gripping elementsl the lower ends of which are enclosed by the skirt 5 of cap-2.
Bulb gripping elements 4 are preferably of elongated U shape, each having a bight portion 6 which is adapted to engage an electric light bulb 'I or Ia, and depending legs 8 having lower portions 9 and lower ends II] as best shown in Figure 3. Preferably these U-shaped bulb gripping elements 4 are shaped so that lower portions 9 are closer together than opposing sides of bight portions 6, so as to be better adapted to engage a bulb.
As illustrated in Figure 3, spaced holes 3a are formed in the end 3 of cap 2. These holes are shaped so as to fit legs 8 snugly, and are spaced from the axis of the pole with their centers slightly farther from the axis of the pole than are the centers of ends III in the assembled condition. When assembled as illustrated in Figure 1, bulb gripping elements 4 have their lower ends I0 secured to pole I while their upper portions project through end 3 of resilent cap 2 and outwardly beyond the end of the pole. Resilient cap 2 resiliently holds legs 8 in proper position and biases bulb gripping elements 4 toward a closed position.
Each bulb gripping element 4 is preferably made of a single length of relatively stiff wire II. Extending approximately at right angles from "the lower ends Ill of legs 8 are short extensions I2. Wire I I is preferably covered from end to end, that is between ends Ill-I0 but not on extensions I2 I2, by a resilient cover I3 which may be of soft rubber.
Spaced around the end of pole I there may be a plurality of grooves I4 extending longitudinally and parallel to the axis of the pole I which are adapted to accommodate the lower portions 9 of the bulb gripipng elements 4, so that when assernbled as illustrated in Figure 1 lower ends 9 of the legs 8 lie in the respective grooves I4. small holes I5 may be provided in th pole perpendicular to its axis adjacent the lower ends of grooves I4. These holes before assembly are preferably slightly smaller in diameter than the diameter of wire I I.
To assemble the device the lower ends 9 of bulb gripping elements 4 are first pushed through holes 3aof cap 2 until extensions l 2 protrude below the bottom of the skirt 5. This subassemb ly is then pushed over the end of pole I so that extensions I2 rest over the holes I5. Extensions I2 are then forced into holes I5 by pressing in on ends I 0. Cap 2 is then pressed down until it is seated on the end of pole I, with skirt 5 overlying ends I0, and lower ends 9 lying in grooves I4.
Alhough not essential, I prefer to provide a ferrule I6 that will surround ends Ill and hold them firmly against the pole. In assembly, the ferrule I6 is first pushed down over the end of the pole below the lower ends of grooves I4. The subassembly of gripping elements and cap is next pushed over the end of the pole and the extensions I2 forced into their holes; the ferrule is then pushed up over ends I0; and cap 2, which may be slightly recessed to accommodate ferrule I6, is finally pressed down into place. As shown in Figure 2, grooves I4 are preferably broader than, but not as deep as, the diameter of resilient cover I3, which is compressed under ferrule I6 into thecross-sectional shape I3a.
In lieu of securing ends ID to the pole by means of extensions I2 embedded in the pole, various other means may be employed. For example, when a wire such as II is used, extensions, in the shape of eyes (not shown) may be formed at ends ID in place of extensions I2, and these may be secured to the pole by screws. When a ferrule or the equivalent, such as It is used to bind the ends II] to the pole extensions I2 or other additional means of securing the ends I 0 to the pole 3 are not essential, the ferrule being sufiicient to secure ends in to pole I.
Ferrule l6 may be placed higher on the pole than indicated on the drawing, but to obtain the maximum resiliency of bulb gripping contact and the widest range of bulb size I prefer to place the ferrule over ends ill as shown.
Bulb gripping elements 4 need not be of the U-shaped form shown in the drawing, but may be elongated elements of any form suitable for engaging a bulb.
While it is essential that bulb gripping ele ments 4 extend through suitable holes in a resilient cap 2, it is not essential that cap 2 have a skirt portion 5, provided that lower ends ID are secured to pole I. That is to say, a cap comprising simply a disc similar to end 3 and having holes 3a therethrough would serve the purpose and be the equivalent of cap 2.
Pole I may be made in sections such as la and 7 lb, joined by suitable fittings lc.
It will be apparent that the resilient cap 3, combined with the method of attaching the bulb gripping elements 4 to the pole l at their bottom ends gives a very resilient type of bulb wrench which will accommodate a wide size range of bulbs and engage them firmly yet resiliently both in gripping action and in torsion when screwing and unscrewing them. The wrench isfurther improved in these respects by covering the bulb gripping elements 4 with re silient covers and by using grooves 14 which are slightly wider than the diameter of the covered bulb gripping elements.
It is believed that the operation will be obvious from the above description. The bulb wrench is simply pushed over the end of a bulb so that the gripping elements 4 resiliently engage it, and the pole l twisted in the desired directiomior screwing or unscrewing.
It will be obvious that various modifications of the describedembodiments of my invention are possible within the scope of the following claims.
