I CURLlNG-IRON.

.srnclrrenrxoiv forming part of Letters Patent No. 752,051, dated February 16, 1904.

Application filed June 22,1903.

To all whom, it may concern:

Be it known that I, WARRENC. DYER, acitizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Curling- Irons; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame. V

This invention relates to curling-irons such as are employed for curling hair; and it has for its object to provide a construction wherein the iron-proper, which is the mandrel over which the hair is curled, may be rotated to wind the hair thereon without requiring rotation of the handles.

A further object of the invention is to provide a construction wherein by bringing the handles together the mandrel may be rotated in one direction and when the handles are separated the mandrel may be caused either to remain stationary or to rotate in the opposite direction. This provides for removal of the mandrel from the hair either by drawing the mandrel out of the curl or by unwinding the hair from the mandrel.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation showing a curling-iron embodying the present invention.

Fig. 2 is a vertical section through the iron in a plane at right angles to the pivot of the handles, the segmental gear being in elevation. Fig. 3 is a perspective View showing the lower portion of the mandrel with the gearwheel thereon. Fig. 4 is a transverse section through the curling-iron in a plane just above the gear-wheel, showing the upper pawl of the gear-wheel engaged with the upper ratchet on the mandrel.

Referring now to the drawings, the present curling-iron comprises aframe including a laterally-broadenedcentral portion 5, above and below which the frame is narrowed, as shown at 6 and 7, said frame being formed integral with and at the upper end of one of the handles 8 of the instrument, the other handle, 9,

of the instrument being pivoted against the Serial No. 162,547. (No model.)

side of the handle 9 at the upper end thereof and close to the frame above referred to, the

upper end'of the handle 9 being provided with a segmental gear 10 for. a purpose to be pres-- ently explained.

Through the formed a perforation 11, and in the lower end of the frame is a socket 12, this perforation upper end of the frame is and socket forming, the bearings in which is rotatabl y and slidably mounted the lower end of a mandrel 13.

The outer end portion of the mandrel 13- that is, the portion which lies exteriorly of the frameis slotted longitudinally, as shown at 14, the free end of the slot being gradually broadened at-15 to facilitate'introduction into the slot of the end of thelock of hair to be curled. After the end of the lock of hair is the mandrel by the upper and lower shoulders 17 and 18 of the frame, which are formed by narrowing the upper and lower portions 6 and 7 of the frame above referred to.

' Upon the mandrel above the pinion 16 are formed ratchet-teeth 19, and additional ratchetteeth 20 are formed on the mandrel below the gear-wheel, the spacing of these groups of ratchet-teeth longitudinally of the mandrel being slightly greater than'thethiekness of height of the pinion. Pivoted upon the upper face of the pinion is a pawl 21, which is held yieldably against the mandrel by the spring 22 in position for engagement with the ratchetteeth 19 when the mandrel is slid downwardly into the frame. Pivoted upon the under face of the pinion is a second pawl 23, disposed in the opposite direction to the pawl 21 and having a spring 24, which holds it yieldably against the mandrel, so that when the mandrel is drawn upwardly to disengage the upper ratchet-teeth 19 from the upper pawl 21 the lower ratchet-teeth 20 will be raised into engagement with the lower pawl.

Thesegmental gear meshes with the pinion, so that by grasping both handles 8 and 9 and moving them toward each other the segmental gear will be caused to rotate the pin- 10m in one dlrectlon, and when the pressure is removed from the handles they will be operated in a reverse direction to reversely rotate the pinion by means of the spring 25, which is disposed between and connected to the handles. With the upper pawl engaged with the upper ratchet-teeth the-pinion will be rotated 19 from the pawl 21 and engage the teeth with the pawl 23, and the handles are then released and permitted to move apart by the ac-' tion of the springs 25. The return movement of the pinion will serve to reversely rotate the mandrel to unwind therefrom a lock'of hair that may. have been previously wound thereon. a

In practice modification of the specific construction shown may be made, and any suit- .able materials and proportions may be used for the various parts without departing from v the spirit of the invention.

What is claimed is- 1-. -A curling-iron comprising a frame provided witha handle, a mandrel rotatably and slidably mounted in theframe, apinion loosely mounted upon the mandrel within the frame and held against sliding movement with the mandrel, reverselyedisposed pawl-and-ratchet mechanisms carried by the pinion and mandrel disposed for alternate operative engagement as the mandrel is r'eciprocated through the pinion, a. second handle pivoted to the first handle, and a gear carried by the second handle and'engaged with the pinion;

2. A curling-iron comprising-a frame provided with a handle, a mandrel rotatably and slidably mounted in the frame, a pinion mounted loosely upon the mandrel within the frameand held against sliding movement with the mandrel, reversely-disposed springpressed 'pawls mounted upon the upper and lower faces respectively of the pinion,ratchet teeth reversibly disposed upon the mandrel above andbelow the pinion forengagement of the corresponding p'awls alternately as the mandrel 's reciprocated, a second handle pivcited to t e first handle, and a gear carried by the second handle and engaged with the pinion.

In testimony whereof I affix my signature in presence of two witnesses.
