To all concern:

, Be it known that-I, EDWARD E. GAnLrrs a citizen of the United States, and a resident of Turtle Creek, in the county of Allegheny and 'State of Pennsylvania, have invented a new and useful Improvement in Irons, oi which the following 1s aspecification.

ed .sad irons and pointed irons.

invention relates to electrically heatparticularly to double Oneobject of my invention is to provide an electrically heated sad iron that shall have reinforced terminal members forming an integral part of the heating element.

Another object of my invention, is to pro-.

vide an electrically heated sad iron that may be easily taken-apart and re-assembled.

Another object of my invention is to provide a sheet-metal unitary terminal member 1 that shall be strong and durable construction. w o

Another object of my 1nvent1on 1s to provide-a positioning member that shall be adapted to so hold the terminal members 'on that they need not be secured to 'thehood ofthe iron.

' A further object of iiwention is to. provide an iron, of the above indlcat'e'd chariacter, that shall be simple. and inexpensive to construct and th'at shallhave its terminal memberslso disposed as to insure uniform 'heatingthroughout and yet cause .the leading-in terminals to be so placed at one s de of the handle as to impose as. little obstruction'to' the proper 'mampulatlon of the lron as j mible g n practising my invention, I provide a tary heating element having a uniformly V distributed winding and unitary terminal members that extend from the center of'theheating element, a top plate having an o n ing therein to permit the terminal mem is to extend toone side of the iron, a hood memberand means disposed between, the hood and the top in position without securing them' to the hood. With this arrangement, the heating plate for so-positioningthe terminal members as to retain the same p more.

parts-broken away of the top plate of the v iron shown in Fig. 1 and Fig. 3 is a top plan view of the heating elementshown in Figs. -1 and 2.

Aniron embodying my invention comprises, in general, a double pointed bottom s ee amnomma Patent Patented Oct. 21, 1919. Application filed June a, 1919. serial Ro.801,m4.

'my, invention; Fig. 2 is a top plan'view with plate 1, a unitary double pointed heating j element-2, a top plate 3, a hood 4, a guide socket 5 for the terminals of the iron and a handle member 6.

The unitary heating element 2, comprisesa metal bottom sheath 7, a, layer 8 of insulating material, a winding 9that is uniformly distributed throughout to insure uniform distribution of heat, a second layer 10 of insulating material, two-plates 11 and 12 havmg portions thereofcut away and so formed as.to' constitute receptacles 13 and 14, a layer 28 of insulating material and a top sheath 29. The conductors 15 from the w1nding 9 are secured to the plates 11 and 12 and the plates 11 and 12 are insulated from the bottom sheath 7 the edges'of which are bent .over to so'retain the elements 7, 8, 9, 10, 11,

12, 13, 14, 28 and 29 in position as to constitute aunitary structure.

Threaded nippleslfi are secured in the receptacles 13 and 14 and receive threaded re' movable bayonet contact members 17. The

portions 13 and 14 extend from substan- 18 in the top plate 3 of the iron. The open-: mg 18 extends from substantially the center of the Iron to one side'thereof. Since the tiallythe center of the element 2 and'are s0,* 1 shaped that they pass through an opening winding 9 is uniformly distributed and the opening 18 extends from a central portion of the member 19, the iron will be uniformly 'heated and will thus have .no cold spots.

Portions of the layer 28 of insulating matenal are bent upwardly to protect the mem-j here :13 and 14 as they pass thnough the opening 18. Screws 20 are provided for securing the element 2' and the top plate 19 to the base plate I and screws 21 are provided for securing the hood 4: of the iron in position. The screws '21 are also adapted to secure the saddle member 23 and the guide socket 5 in position. The handle 6 is secured to the saddle member 23 by a bolt or pin 24:.

An insulating member 25 having a shoulder 26 at one end to engage the opening in the hood 4: and an internal shoulder 27 to fit over the receptacles l3 and 1a is disposed around the members 13, la and 17 and is so clamped between the top plate 3 and the hood t as to effectively support the members 17 and to prevent withdrawing the same to break the lead conductors to the winding 9 when the iron is disconnected by removing the plug connector (not shown).

From the above, it will be seen that it is unnecessary to secure the members 17 to the hood and thus the iron may be easily taken apart and the members 17 may be replaced without taking the iron apart. In order to renew a heating element, it is only necessary to remove the screws 20 and 21. This permits the hood 4k, and top plate19 to be removed and a new heating element inserted. Since the members 17 are di osed at one side of the handle 6 interme iate the legs of the saddle 23, it will be seen that one of the chief difficulties of double pointed irons is removed. That is, the connecting cord is at one side and, consequently, out of the Way. Heretofore, this was not feasible because if the terminals were brought through the top plate at one side, less material would obtain at that side and thus resuit in vcold spots. By my improved construction, since the terminals are brought from the center ofthe iron, the heat is distributed uniformly. 1

My invention is not limited to the specific structure illustrated, as various modifications may be made therein within the spirit and scope of the invention, as set forth in the appended claims.

I claim as my invention:

1. In an electrically heated sad iron, the combination with a double-pointed bottom plate, of a double-pointed heating element having its windings evenly distributed, and. a top plate having an opening therein extending from the central portion of the bottom thereof to a side portion of the top to permit the leads to the heating element to pass therethrough.

2. In an electrically heated said iron, the

combination with a double-pointed bottom plate, a double-pointed heating element, a top plate, and a hood member, of terminal members for the heating element integral therewith and passing through the top plate to a posltion adjacent the hood member, anda bushing disposed between the hood member and the top plate to secure the terminal members in position.

In an electrically heated sad iron, the

combination with a double-pointed bottom' plate, a double-pointed heating element, a top plate, and a hood member, of terminal members for the heating element integral therewith and passing through the to plate to the hood member, and a remova le insulating bushing disposed around the termi- .nal members between the hood member and the top plate.

l. In an electrically heated said iron, the combination with a bottom plate, a heating element, a top plate, and a hood member, of terminal members for the heating element integral therewith and passing through the top plate, bayonet contact members secured to the terminal members, and means disposed around the terminal and the bayonet members and wedged between the hood and the top plate for securing the said members in position with respect to the hood member where they pass through the top plate.

In an electrically heated sad iron, the combination with a bottom plate, a heating element, a top plate, and a hood member, of a terminal member for the heating element integral therewith and passing through the top plate to one side of the hood members and a removable insulating member so wedged between the hood member and the top plate as to secure the terminal member prising a terminal plate having portions thereof formed to constitute a receptacle, an internally-threaded member disposed in the receptacle so formed and a screw-threaded bayonet contact member disposed in the threaded member.

8. A-heating element for a sad iron com prising a terminal plate having integral portions thereof formed to constitute a to: bular member, and a contact member. removably disposed inthe tubular member. 9. In an electrically heated. sad iron, the combination with a double-pointed bottom plate, of a double-pointed unitary heating element having its terminals at the center thereof, a uniformly distributed winding and a oop plate having an opening therein to permit theterminals from the center of the heating element to pass therethrough to a; position to one side thereof.

10-. In an electrically heated sad iron, .the combination with a double-pointed bottom plate, a double-pointed heating element, and

a handle, of a top-plate and a hood to the terminalsof the heating element to extend from the center of the heating element to a position at one side of the handle.

11. In an electrically heated sad iron, the combination with a heating element, a top plate and a hood, of terminal members integral with the heating element and extending freely through the top plate'and the hood, and freely removable means wedged between the hoodand the top plate for securing the terminal members in position.
