FINGER GRIP COMB Filed Sept. 13, 1941 Patented Aug. 11, 1942 ETED STATES PATENT FFIQE Claims.

Ihis invention relates to improvements in finger grip combs and may be regarded as an improvement over the finger grip comb disclosed in my prior United States Letters Patent No. 2,150,260, issued March 14, 1939.

An object of the present invention is to provide an improved finger grip comb having the finger receiving opening extending laterally through the comb at approximately the center of gravity of the comb. In my prior patent there is disclosed a finger grip comb having a back from which project teeth the back being extended to provide a rat tail and one or more finger grip openings located at the juncture of the rat tail extension with the back of the comb. In that construction the finger grip openings are not located at approximately the center of gravity of the comb so that when the comb is being used the extended weight of the comb beyond the finger grip opening must be supported in cantilever fashion by the hand of the user. If the index finger is inserted through the finger opening and the second, third, and fourth fingers, or the third and fourth fingers alone, are positioned over the rat tail extension very little purchase is afiorded by the rat tail extension to resist twisting of the comb. By means of the present invention by having the finger grip opening located at the center of gravity the comb is better balanced so as not to become tiresome in the hands of the user and a greater purchase is afforded for the second, third, and fourth fingers of the user to resist twisting of the comb.

Another object of the invention is to provide a finger grip comb having a series of coarse teeth and a series of fine teeth, the fine teeth projecting downwardly from one end of the back and the coarse teeth projecting upwardly from the other end of the back. By having the finger grip opening at the approximate center of gravity the comb may be quickly turned or rotated on the index finger that is extended through the finger grip opening to quickly and automatically effect a change from coarse teeth to fine teeth or Vice versa.

With the foregoing and other objects in View, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawing for an illustrative embodiment of the invention, wherein:

Figure 1 is a view in side elevation of an improved comb embodying the present invention; and

Fig. 2 is a top plan view of the same.

Referring to the accompanying drawing wherein similar reference characters designate similar parts throughout, the improved comb comprises a suitable back generally designated at I0. The comb may be formed of any desirable material and is preferably planar in configuration tapering from its center toward both ends as indicated in Fig. 2.

A series of fine teeth II project downwardly from the back adjacent one end thereof. These teeth are preferably formed integral with the back and are somewhat thinner and more closely arranged than a similar series of coarse teeth l2 which project upwardly from adjacent the opposite end of the back.

A finger grip opening 13 of a a size to accommodate the index finger is formed laterally through the back at approximately the center of the comb so as to be arranged at approximately the center of gravity, it being understood that the weights of the fine teeth H and the coarse teeth l2 and the portions of the back from which these two series of teeth project are approximately equal. If for any reason one end of the comb should be made heavier than the other then the finger grip opening I3 is shifted so as to still extend through the back at approximately the center of gravity of the comb.

The top and bottom edges of the back above and below the opening l3 are convexly shaped as at [4 and I5 near the inner ends of our respective series of teeth to provide thumb rests.

In using the comb the index finger is inserted through the finger grip opening [3 and the thumb positioned against the thumb rest 15 if the comb is held in the position illustrated in Fig. 1 wherein the fine teeth I I are available for use. As the comb is equally balanced on opposite sides of the finger grip opening it will not become tiresome in the hands of the user. The second, third, and fourth fingers may be positioned over the upper ends of the coarse teeth I2 which forms an adequate anti-friction surface both at the top edge of the comb and along its sides to efiectively resist twisting of the comb in the hands of the user.

In the event that the operator or uses wishes to shift the comb and use the coarse teeth l2 in place of the fine teeth H the comb is allowed to remain on the index finger and the second, third, and fourth fingers may be positioned beneath the back of the comb below the coarse teeth I2. The comb can then be quickly turned on the index finger, this being readily accomplished by the balanced effect of the comb and the coarse teeth I 2 caused to assume the position originally assumed by the fine teeth II. In this way, a very quick and convenient shift may be made from the fine toothed position to the coarse toothed position and vice versa.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. A comb having a back, a series of fine teeth projecting downwardly from one end of the back, a series of coarse teeth projecting upwardly from the other end of the back, and a finger grip opening extending through the back between the sets of teeth.

2. A comb having a back, a series of fine teeth projecting downwardly from one end of the back, a series of coarse teeth projecting upwardly from the other end of the back, and a finger grip opening extending through the back between the sets of teeth arranged at approximately the center of gravity of the comb.

3. A comb having a back, a series of fine teeth projecting downwardly from one end'of the back, 25

a series of coarse teeth projecting upwardly from the other end of the back, and a finger grip opening extending through the back between the sets of teeth, the edges of the back above and below the opening being concavely shaped adjacent the inner ends of the series of teeth to provide thumb rests.

4. A comb having a back, a series of fine teeth projecting downwardly from one end of the back, a series of coarse teeth projecting upwardly from the other end of the back, and a finger grip opening extending through the back between the sets of teeth, the ends of the series of fine teeth being approximately even with the back below the coarse teeth, and the ends of the coarse teeth be. ing approximately fiush with the back above the fine teeth.

5. A comb having a back with teeth thereon, and a finger grip opening extending laterally through the comb at approximately its center of gravity, the edge of the back adjacent the inner end of the series of teeth being concavely shaped to provide a thumb rest.

ETHEL YATES BERRY.
