SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 786,733, dated August 18, 1903. Application filed December 11, 1902. serial No. 134,771. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES WILLIAM JOHNSTON, a citizen of the United States, and a resident of Meeteetse, in the county of Bighorn and State of Wyoming, have invented a new and Improved Sad-Iron, of which the following is a full, clear, and exact description.

My invention relates to an improvement in sad-irons, especiallythat class of irons which are provided with removable handles.

The purpose of the invention is to so construct the handle and the body of the iron that one can be quickly and conveniently separated from the other and the two parts as readily and expeditiously connected and to provide such a locking engagement between the handle and the body of the iron that there will be no side motion of the handle at any time while the parts are in looking engagement.

Another purpose of the invention is to provide a simple locking device for the handle and means for readily placing the handle centrally in pivotal engagement with the body of the iron and locking the handle to the body of the iron between either end of the body and the pivot-point carried thereby and also to provide means for limiting the pivotal movement of the handle upon the body of the 1I0Il.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective, view of the improved iron and the handle, the two being shown in looking connection. Fig.2 is a longitudinal vertical section through the body of the iron and a sectional side elevation of the handle applied to the body; and Fig. 3 is a plan view of the body of the iron, the handle being shown in dotted lines and in its initial position upon the body of the iron. Fig. 4 is a detail sectional view illustrating the manner in which the handle is attached to the body of the iron.

The body A of the iron is given any desired shape. In the drawings it is shown pointed cured to the upper portion of the iron in any approved manner, and between said capplate and iron a packing 11, of asbestos or other non-heat-conducting material, is prop erlylaid, as is shown in Fig. 2. The pivot-pin 13'extends from the upper central portion of the body A of the iron through an opening 12 in the cap-plate, and at each side of the pivot pin 13, at an equal distance therefrom, apertures 14 and 14 aremade in the said capplate 10. Further, a flange 15 is formed upon the upper portion of the cap-plate at each end, which flanges are continued at the side marginal portions of the cap-plate, having opposing marginal positions, as is particularly shown in Figs. 1 and 3. Each flange 15 is provided with an undercut recess 16 in its inner face, as is also best shown in Figs. 1 and 2, and these recesses extend from end to end of the flanges.

The handle B consists of an upper section 17", legs 17, connected therewith, and a baseplate 17, the end portions 18 whereof, as is best shown in dotted lines in Fig. 3, are oppositely or diagonally curved to fit in the grooves 16 of the flanges 15 on the body of the iron when the handle is brought in looking engagement with the said body. The baseplate 17 of the handle 13 has a central opening 19 made therein to receive the pin 13 of the body of the iron when the handle is to be fastened to the said body, and in order that the attachment between the two parts may be quickly and conveniently made the bottom of the opening 19 is more or less beveled or countersunk, as is shown in Fig. 2%. A second opening 19 is made in the base-plate 17 of the handle, having such position that when the central opening in the base-plate receives the pin 13 of the body of the iron the opening 19 will when the handle is in its locking position be over one or the other of the openings 14: or 11 in the cap-plate 10 of the body of the iron. A bearing 20 is constructed over the opening 19 and in this bearing a rod 21 is mounted to slide, having a bolt-head 22 at its lower end arranged to pass through the opening 19 and to enter at each end. Preferably a cap-plate 10 is seeither of the base- openings 14 or 14 and lock the handle B to the body A of the iron.

lhe bolt-head 22 of the rod 21 is normally held in looking position by a spring 23, preferably of V or U shape, through which the rod 21 loosely passes at the terminals of the spring, which terminals of the spring rest, respectively, against the upper portion of the bearing 20 and against the upper portion of the bolt-head 22, as is shown in Fig. 2. A knob 24 is detachably connected to the upper end of the rod 21, whereby the rod may be drawn upward to relieve the handle from looking engagement with the body of the iron. It is obvious that should the spring 23 become broken it maybe readily replaced by a perfect one, since upon removing the knob 24 the bolt-rod 21 can be quickly withdrawn and threaded through the new spring, as the rod 21 is passed loosely through the knob, and the knob is held in place by a nut screwed upon the upper end of the rod and preferably countersunk in the knob, as is shown in Fig. 4.

In operation when the handle is to be attached to the body of the iron the handle is placed upon the body, the opening 19 in the handle receiving the pivot-pin 13 of the body. The handle is now quickly turned until its opposing curved ends 18 enter the grooves 16 in the flanges 15 of the body, and the moment that the handle is thus seated upon the body the bolt-head 22. of the spring-controlled rod 21 will enter either one of the openings 14 or 14 of the body and insure a locking engagement between the body and its handle. It is further obvious that when such a locking engagement takes place the handle cannot move sidewise and is as firmly secured to the body as though the handle were an integral portion thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a sad-iron, a body-section having a central pin extending beyond its upper surface, and undercut end flanges oppositely and diagonally disposed, the upper surface of the said body being likewise provided with apertures between the pivot-pin and the flanges, a handle provided with a base-plate having its end portions oppositely curved to fit in the undercut portions of the flanges of the body, the said base of thehandle being provided with an opening to receive the said pivot-pin of the body, and a spring-controlled locking-bolt carried by the handle, adapted to enter either of the apertures in the said body, as set forth.

2. In a sad-iron, the combination with a body, a cap-plate secured to the said body, a packing of a non-heat-conducting material between the cap-plate and the body, a central pivot-pin extending beyond the upper surface of the cap-plate, and flanges at each end of the said cap-plate, which flanges extend from the ends along opposing side marginal edges of the said cap-plate, the flanges being undercut at their inner faces from end to end, the said cap-plate being also provided with apertures at each side of the pivot-pin at equal distances therefrom, of a handle, a base-plate secured to the handle, provided with a central opening to receive the pivotpin of the body, a bearing located on the said base-plate of the handle, a spring-controlled bolt-rod carried by the said bearing and extending through the said base-plate, adapted to enter either one of the apertures in the cap-plate of the said body, and a removable handle for the bolt-rod, all operating substantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES WILLIAM JOHNSTON.
