A. G. SWENSON 2,479,429 LOCK FOR HINGED HANDLES OF TRAVEL IRONS Filed Oct. 2, 1947 folding handles for fiatirons.

Patented Aug. 16, 1949 OFFICE LOCK FOR HINGED HANDLES OF TRAVEL IRONS Alfred G. Swenson,

General Electric New York Ontario, Calif., assignor to Company, a corporation of 9 Claims. 1

This invention relates to a handle support and assembly construction, and more particularly Handles for such devices must be designed not only for small area when folded, but also for rigidity or positive looking in their opened or unfolded position. Other objects include simplicity of design, few parts, in-

expensiveness and general ruggedness.

These objects and others are obtained in my invention through the combination of parts and constructions described in the following specification. For a more complete understanding of this invention, reference should be had to the accompanying drawing in which Fig. 1 is a side view and partial section of a fiatiron and handle according to my invention, showing in full lines the handle and handle lock in collapsed position, and in dotted lines the handle and part of the lock in opened position; Fig. 2 is a plan view of the device of Fig. 1 with certain parts broken away; Fig. 3 is a side sectional view of the handle and handle lock pivot with the parts in their opened and locked positions, the unlocked position of the lock being indicated in dotted lines, and Fig. 4 is a broken perspective view of the handle and lockingparts showing their manner of mounting and the opened and locked position.

(In the form shownin the drawings, which is used as an example, the body of the iron consists of the customary soleplate ID, to which is fas- .tenedla usual top cover plate I l which overhangs .the heel ['2 of the soleplate. A bottom cover plate "covers the overhanging portionand is stepped up slightly from the plane of the soleplate.

" Within or above the soleplate a heating element I4. is provided, having the usual leads l5 and I 6 which are connected to plug terminals I1 and I8, supported by but insulated from the'top cover plate.

The constructions described above are more or less conventional in character and form no part of the present invention. However, the folding handle. its manner of mounting and locking and the manner of mounting the bottom cover plate are considered tobe novel and a part of my infi Om The handle, the parts for locking t w handle, and structure for mounting the bottom cover plate are all held in place 'by a single element which is shown in the drawings as a U- shaped bracket l9. This bracket has three ears,

one in the bight of the U, toward the front of the iron, and one in each side of the U, toward the rear of the iron. I have called these ears 2| and 22-22. These ears all pass through holes or slots in the top cover plate. In assembly, the front ear g V the back of the latch 2| is bent and then hooked through a slot in the top cover plate. The bracket is then brought down at the back until the back ears 22-22 pass through their slots in the cover plate. The back ears are then twisted to hold the bracket securely in place. The two back ears 22--22 are each provided with a notch 23 for a purpose to be later described.

The handle 24 is shown as a bifurcated member which straddles and is pivoted to the bracket l9 by means of pins 25-25 which are driven through the legs of the handle into hearing holes 26-45 of the bracket. In its collapsed or folded position the handle lies close to the top cover of the iron as shown in full lines in Fig. 1. When in use, the handle is lifted to the position shown in dotted lines. In order to hold the handle in its operating position, a latching formation, shown as a projection or latching shelf 21, is provided in the crotch of the bifurcation, and this projection is engaged by a complementary latching formation or offset portion28 on a latch piece 29 which is hinged or pivoted in the front-ear 2 l of bracket IS. A lip 3| at the top of this latch piece engages with the projection 21 on the handle to prevent the handle from rising higher than its operating position. The latch piece is normally urged forward toward a position where it may engage the handle by a Z-shaped spring 32, one end of which is also held by the bracket ear 2l. The center leg of this spring lies along the top cover plate, and its free end presses against piece to urge it in the proper direction.

It will therefore be seen that by raising the handle, it will become latched in its upward or operating position because of the action of the spring 32 and the latch piece 29. However, a light pressure on the handle will permit it to be lowered to its folded position. In order to prevent this, a handle locking lever 33 is provided. This lever is of generally U shape, and is pivoted to the bracket IS on the same pins 25-25 which pivotally support the handle. The locking action is obtained by arms 34-34 which extend forwardly on either side and are provided with inturned cam surfaces 3535 which bear against pressure areas 36-36 on the latching piece. For manipulating this locking lever a depression 37 is formed in its edge, so that this lever can be moved easily forward and backward. In its forward position the lever disengages from the latch In its fully open position the locking lever will lock the handle and latch piece rigidly together when the handle also is in its opened position. In this position the locking lever can act as a heel stand for the iron in cooperation with the back edge of the iron by virtue of dimples or deformations lit-38 on the sides of arms 3E-'34. ihese deformations frictionally engage the inside of the legs of the handle. the cam surfaces -35 and the areas 36-36 on the latch piece will also tend to hold the locking lever in its opened position.

It is to be understood that when the locking lever 33 is fully opened it also functions as a plug socket for receiving the usual electrical supply plug (not shown) that engages the terminals H and I8.

Also as shown in the drawings, when the locking lever is in its fully opened position, its back surface is adjacent and substantially perpendicular to the heel end of the top cover so that the iron may be tilted backward for resting. Because of friction of the parts, this is possible whether the attachment plug is inserted on the terminals or not.

This feature is important in folding irons of the type described, because usually they are not provided with automatic temperature controls, and the plug must be pulled occasionally to keep the iron from getting too hot.

The same bracket which holds the handle and handle locking parts in place is used to secure the bottom cover plate l3 in place. This is accomplished by using upstanding ears 39-39 which are welded or otherwise fastened to the back edge of the soleplate, and provided with slots 4|-4l. Lips 42-42 on the front edge of the bottom cover plate engage in these slots, and hold this edge from lateral or vertical displacement. The rear edge of the bottom cover plate is held in place by a spring clip 43 which may be riveted to the plate and have an angular portion M near its free end. This angular portion snaps into the notches 2323 of the ears 22-22 on the U-shaped bracket, and finally holds the entire assembly together. Interfitting flanges 20 on the top cover plate and S ll on the bottom cover plate prevent relative shifting of these parts after they are snapped together.

While I have shown and described a particular embodiment of my invention, it will occur to those skilled in the art that various changes and modifications may be made without departing from my invention, and I therefore aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent of the United States is:
