SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 679,256, dated July 23, 1901.

Application filed March 23, 1899.

To all whom it may concern:

Be it known that I, THOMAS C. EDWARDS, a citizen of the United States, and a resident of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

My invention relates to self heating reversible sad-irons, and has for its object to so construct the several parts of such an implement that it will be rendered cheaper and more durable in construction and more convenient and efiective in use.

My invention is an improvement on the self-heating sad-iron described, shown, and claimed in my application filed August 25, 1898, Serial No. 689,475.

My invention consists in certain novel features of construction, hereinafter fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a sad-iron embodying the features of my invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section. Fig. 4 is a plan view of one of the sections of the body portion or iron proper. Fig. 5 represents the segregated parts by means of which the rear ends of the iron-sections are secured together and trunnioned in the handle. Fig. 6 is a detail view illustrating the means for holding the burner-tube in the handle and permitting its ready removal therefrom. Fig. 7 is a detail view showing the connection of the reversing-lever with the trunnion-screw of the iron. Fig. 8 is a detail perspective view showing the connection between the reversing-lever and the hanger, the parts being disconnected.

1 represents the body of the iron, 2 a handle in which the iron is trunnioned to make it reversible, and 3 a burner-tube which enters the rear end of the iron and is held by a slllitable bracket 4, projecting from the hand e 2.

The body portion 1 consists of two similarly-constructed body-sections 5, having at their front and rear ends overlapping ears 6 7, respectively. As shown in Fig. 2, a screw 8 passes through the front ears 6 and forms a trunnion for one end of the handle 2. The

Serial No. 710,211. (No model.)

screw Sis provided with an enlarged and vertically-elongated head 9, formed with a slot 10 to provide a mounting for a reversing-lever 11, which is bifurcated, as shown in Fig. 7, and secured by a screw-pin 12, so as to be vertically and outwardly movable upon the screw-head, but not transversely movable relatively thereto. The upper end of the reversing-lever 11 has a tapered enlargement 13, which rests in a correspondingly-formed socket 13 of a hanger 14, which socket communicates with an outwardlyopening slot 15. The reversing-lever 11 terminates in a knob or handle 16, by which it may be lifted until a reduced portion of its length comes opposite the slot 15, when it is readily swung outward and released from the hanger, so that it may be moved laterally to reverse the iron. The rear ends of the sections are held together by means of a thimble 17, which passes outward through enlarged openings in the ears 7 and projects sufficiently beyond the same to form a trunnion, which enters the ring 18 on the rear end of the handle 2. The ring 18 is secured to the protruding end of the thimble 17 by means of a set-screw 19 and the parts thus locked securely in position. The rear ears 7 are halved together in such a manner that the outer ear provides a seat 20 for the inner ear 7, and by this means the parts are centered or fixed against lateral displacement, and a very much more rigid connection is provided. The thimble 17 is of sufficient size to receive the spider 21, which supports the burner 3 within the iron and preserves sufficient space around it to permit the passage of the proper quantity of air from the rear.

The burner-tube 3 fits in a slot 22 in the bracket 4 and is secured therein by means of a latch 23, which is pivoted at 24 to swing in a vertical plane and provided with a crossbar 25, which rests upon the bracket to hold the latch 23 across the mouth of the slot. The latch is strengthened against outward displacement by means of a projection 26 on the bar 25, which engages behind the bracket, as shown in Fig. 6.

The sections of the iron are of peculiar interior construction. The inner surface of each is covered by a number of round projections 27, arranged in rows or series and suitably spaced apart to divide up the interior of the iron into a number of circuitous air-passages. The central row of projections 28 are terminated short of the dividing-plane of the iron for the purpose of leaving room for the burner 23*; but the two outer series 29 and 30 on either side are extended to the dividing-plane between the sections, and the ends of the corresponding projections from the two sections meet, as shown in Fig. 3. The object of so constructing the iron is to provide, as stated, a number of circuitous airpassages in which the gases will'become thoroughly mixed with the air, while the projections receive impingement of the burning gasesand insure rapid and continuous conduction of the heat to the working surfaces. The sections of the iron are spaced apart by the ears 6 and 7, as well as by the projections 29 and 30. This leaves the sides of the iron open. For the purpose of dividing up the inflow of air for the support of combustion and confining the flame within the iron the sides of the iron are covered by wire-cloth 31, for the confinement of which the sections of the iron are provided with vertical flanges 32. (See Fig. 3.)

An iron constructed as above described will insure perfect combustion of the fuel which is discharged through jet-openings in the burner-tube and the heating eifect will be rapid. Moreover, the meeting of the projections 29 and 30 will insure conduction of heat from the upper to the lower section and keep the latter to a Working temperature for a longer period.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a sad-iron, the combination with a sectional body, the sections of which have overlapping lips, of handle-brackets carrying bearings which pass through said overlapping lips thus locking the sections of the body together and locking the handle to the body.

2. In a sad-iron the combination with a sectional body, the sections of which have overlapping lips, of a handle the arms or brackets of which carry bearings passing through openings in said lips and a device for locking the handle against movement.

3. In a sad-iron, the combination with a sectional body, each section having overlapping lips, of a handle the arms or brackets of which have bearings passing through openings in said overlapping lips, and a removable burner-pipe passing through one of said bearings.
