Similarly, at the opposite end of the control member, a pair of arcuate brackets 26 is laterally extended from the control member exteriorly of the body in slidable peripheral embracing engagement therewith. For convenience in supporting the comb of the present invention, a clip 21 is mounted longitudinally of the body on the cap 24 intermediate the brackets 25.
As clearly evident in Figs. 3, 4, and 5, the control member 22 is located in predetermined spaced relation to the openings I 2 and I'I through the body I and locking slide I5. A plurality of substantially uniform elongated teeth are pivotally mounted in the contol member 22 and individually extended through aligned openings I1 and I2. It ill be noted that there is a series of teeth pivotally mounted in each of the grooves 23, each of which series is extended through a corresponding series of aligned openings in the i able material having adequate resilience to permit sufficient compression of the studs 32 for snapinsertion of the teeth upwardly into their respectiveY grooves and expansion of the studs intotheir respective indentations. The studs 32 exemplify suitable pivotal axes for the teeth 3s transversely disposed to the control member 22 and aligned openings I7.
.The teeth are of a length appreciab-ly greater than thespacing of the control member 22 from the openings I2 and I'I so that when the control member isl moved to bring the pivotal mounting of v.its teeth 30 into substantial alignment with said'teeths respective openings 'I and I2, the teeth 'will be 'extended from the .body suiciently for combing convenience. In order releasably to constrain the control member in such slidable position with -the teeth-extended from the body in substantially right angular relation thereto, inwardlyconvex dimples 33 are formed in the body in positions overlaid :by the brackets 25 and 26 when the control member is in said position and complementary dimples 34 formed in the brackets for releasable vengagement with the convex dimples 33. U
-When the controlmember 22 is slid toward the handle end I8 of the jcomb by overcoming the resilient nesting of the dimples 33 and 34, the teeth 30 are retracted into the body and the extended end portions 35 located within the openings I2, as shown in Fig. 3.A The length of the slotlII is preferably such that movement of the control member 22 further toward the handle end of the body is Yprecluded by the abutting of the control member against the end of the slot. In
order releasably to 'retain the control member'in the position illustrated in Figs. 1 and 3, dimples Bare formed in the Ibody in positions to nest with the dimples 34with the control member inretractedposition. I
As also shown Vin Fig. 3 the edges of the open'.- ings II inthe locking slide I5 are preferably beveled endwardly of the body I8, as illustrated at 31 in`Figs. 3 and 4. Further, the body at the edges of the openings I2 toward the handle end I8 of the .bodyare beveled at V38 tol facilitate movement of the control member 22 and thus the boss toward the end I9 of the body sufficiently to bring the teeth 30 into substantial right angular relation to the body. The engagementis made just prior to releasable association of the V dimples 34 and 33 and the continued movement of the control member and locking slide to bring the dimples into releasable engagement causes the control slide to move in unitary relation with the control member and relatively to the body whereby the teeth 3U extended through the openings I2 and I'I are subjected to shearing forces conducive to dependable clamping of the teeth in operable position.
After the comb is assembled, plugs 53 of desired artistic form are tted in closing relation tothe opposite end portions of the body and secured therein as by sweating, soldering, welding or other means appropriate to the materials em'- ployed.
Operation The4 operation of the device is `believed to be clearly apparent and is briefly summarized at this point.
For stowing and carrying convenience, the control member 22 is drawn toward the handle end I8 of the body I0 and releasably maintained in such position by the nested association of the dimples 34 and 36. This position of the control member frees the locking slide from restraint and draws the teeth 30 upwardly through the openings I2 and II into the retracted position shown in Fig. 3. In such retracted and compacted condition the teeth are shielded from damage and soiling and containers such as pockets, purses and the like in which the comb vis stowed or carried protected against damage fromv the teeth.
The comb is conveniently supported, if desired, by means of the clip 2l on the edge of a pocket or in other convenient position much the well known manner of fountain pens, pencils and the like.
VTo employ the comb, the control memberl22 is thrust toward the end, IQ ofthe body until the dimples 33 and 34 are in releasably nested association. As previously described, the movement ,of the control member slides the teeth 30 downwardly through the openings I'I and I2 and pivots the teeth to thepositionsshown in Figs. 2 and 4 in substantially right angular relation to -the body I9. With the'control member 22 positioned as described, the boss 40 urges thelock ing slide I5 endwardly in the .body I0 and subjectsthe teeth to a clamping action between the body and locking slide incident toa slight misalignmentof the openings I2 and II. The employment of a plurality of rows or series of teeth slidably positioned in a plurality of series of openings I2 and I'I enables the provision of aY comb having closely adjacent teeth in relation to the direction of movement of .the comb teeth through hair during normal employment of the comb.
