CURLING-IRON.

SPECIFICATION formingpart of Letters Patent No. 520,904, dated June 5, 1894.

Application filed October 6 1 898 To all whom it may concern.-

13c it known that I, CHARLES F. SNYDER, a c tizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Curling-Irons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, wherein like symbols of reference refer to like parts Wherever they occur, and in which Figure 1 is a side elevation of my improved curling iron. Fig. 2 is a sectional view, on line 2-2 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a similar view, taken on lines 3-3, Fig. 1, looking in the direction of the arrows. Fig. 4 is a detail sectional view of the hinge joint of the operating or pivoted handle.

My invention relates to a new and useful improvement in curling irons, and is designed more particularly as an improvement upon a construction such as is shown and described in an application filed by me June 24, 1893, serially numbered 478,705.

The features of novelty in this present invention reside in the combination witha pair' of curling tongs, comprising a rod and pivoted jaw, of a handle, in which said rod is mounted,a handle pivoted to the first-named handle, a pinion loosely mounted on the rod, a rack on the pivoted handle for engaging the pinion and aratchet wheel fixedly mounted on the rod with which wheel a pawl engages, which pawl is carried by the pinion, for rotating the rod and its carried clamping jaw. Other minor details reside in the peculiar construction, arrangement, and combination of the parts, all as will hereinafter be more fully described and afterward pointed out in the claims.

In the drawings, 1 indicates the rigid jaw, circular in crosssection, as shown, upon which is pivoted, as at 2, the clamping jaw 2, which is concavo-convex incross-section adapting it to closely fit the rigid jaw 1 and tightly-clasp or bind the hair therebetween. A spring 3, is placed beneath the handle of this pivoted bar, and tends at all times to maintain close relation between the parts.

This rigid jaw or rod 1, is mounted in bear= Serial No 487,356- (No model.)

ings formed on the handle piece 5, in which it is adapted to turn. The forward bearing 6 consists, as shown, in an upturned piece 6*, which has an opening formed therein for the rod, while the rear bearing 7 has an opening of less diameter than the rod 1, which is reduced at this pointto fit in said opening, its end beyond said bearing 7 being provided with a cross-pin 8 or other means to prevent longitudinal movement. Pivoted to the bearing 6 on the side Wings 6, by a pin 9", is a handle 9, which has its end extending forward such a distance as to overlap the upturned piece 6 in front of the pivot-pin 9*, thus preventing the handle from being forced out too far by its spring 10,- which is interposed therebetween, and the handle-piece 5. These handles 5 and 9 are preferably faced with non-heat-conducting material, as indicated at 11. Loosely mounted upon the rod 1, is a pawl-carrying disk 12, which has conjoined thereto a pinion 13, with which is adapted to engage and be operated by a rack 14, which is mounted on pivoted handle 9. The disk 12 has mounted thereon a springpawl 15 which is adapted to engage and opcrate a ratchet wheel 16 fixedly mounted on the rod 1. To prevent a back movement of the ratchet-wheel and the consequent return of the rod 1, should it be desired to curl the hair tightly, I mount upon the bearing 7 a spring-pawl 17, which also engages said ratchet-wheel.

The operation is as follows: The hair being clamped between the jaws 1 and 2, the handle9 is forced toward the handle 5, causing the rack 14 to rotate the pinion 13 and disk 12, which, by its engagement, with the ratchet-wheel 16, through the medium of the pawl 15, causes the rod 1 to revolve, the pawl 17 slipping over the ratchet wheel. When pressure is relieved from the handle 9, the spring 10 asserts itself and causes the same to be forced outward until its extreme forward end comes in contact with the upturned lip 6, at which point the outward movement of the handle 9 is arrested. During this outward movement of the handle, the rack 14 will cause the pinion 13 to revolve in a direction opposite that first described, permitting the pawl 15 to ride over the ratchet-teeth of the wheel 16 to set itself for another operation, pawl 17, in the mean time, preventing the back movement of the ratchet wheel 16 and the rod 1 upon which it is fixedly mounted.

I am aware that many minor changes in the construction and arrangement of the parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent. is

1; In combination with a pair of curling tongs, comprising a rod and pivoted jaw, of a handle in which said rod is revolubly mounted, said handle being formed with an upturned lip at its forward end, and ears or wings on each side of said lip, pivot pin passing through said wings, a handle mounted on said pivot pin, which handle extends forward beyond the lip with which it contacts to arrest its outward movement, and means on the rod, which are operated by the pivot handle, for rotating said rod, and its carried clamping jaw, substantially as described.

2. In combination with a pair of curling tongs, comprising a rod and pivoted jaw, of a handle in which said rod is revolubly mounted, a handle pivoted to the first-named handle, a pinion loosely mounted on the rod, a rack on the pivoted handle for engaging the pinion, and a ratchet wheel fixedly mounted on the rod, which is adapted to be engaged by a pawl carried by the pinion for rotating the rod and its carried clamping jaw, substantially as described.

3. In combination with a pair of curling tongs, comprising a rod and pivoted jaw, of a handle in which said rod is revolnbly mounted, a handle pivoted to the first-named han dle, a spring interposed between the two handles, a pinion loosely mounted on the rod, which carries a pawl for actuating a ratchet wheel fixedly mounted on the rod, a stationarily mounted pawl for preventing a back movement of said ratchet wheel, and a rack on the pivoted handle which engages and opcrates the pinion, substantially as described.

In testimony whereof I hereunto aihx my signature, in presence of two witnesses, this 12th day of September, 1893.

CHARLES F. SNYDER.
