ELECTRIC SADIRON Filed Jag. 25, 1934 ATTORNEY Patented July rl *,y 1934 UNITED STATES Emc'rarc saumon Michael N. Masvey Application January 25,

8 Claims.

My invention relates to.electric sadirons used for ironing or pressing clothing and linen.

Ordinary electric sadirons, when connected with the electric current but not used for press-- ing, must be placed on`a special stand in order to protectthe goods from being burned if the iron is left on them. The users are instructed not to leave the iron on the work when under current, but there is always a possibility that the user may forget to disconnect the switch when leaving the work temporarily, and serious res have been started through such neglect. With my improved iron the work cannot be burned, the iron being in this respect foolproof. I provide my iron for this purpose with a heavy backrest at an angle with the ironing surface, and I also provide an additional movable weight in the handle. The latter is hooked to the iron and is retained in the loperative position by the pressure on the'handlc from the users hand. I arrange the movable weight so that when the iron is held in the operative position, the weight is automatically moved forward so as to distribute the weight more or less evenly over the pressing surface. If the hand is removed from the handle, however, then the hook on the handle is automatically released, a spring swings the back rest backward, thereby causing also the movable weight to shift back thereby causing the iron to tilt Jbackward raising the hot portion in the air. -In this position the iron, while remaining under current and hot, ready for use, cannot damage the work, resting on it with its c ool back side.

The operation' of my iron is therefore fully automatic, as it takes the safe tilted position immediately if the hand is removed from the handle. I alsol provide an arrangement that if the iron istilted Without releasing the grip on the handle, th en it will remain in theoperativc position, with the handle hooked to the ironing portion, although tilted into the safe position.

My invention is more fully described inthe accompanying specification and drawing in Which- Fig. 1 is a sectional elevation of my iron, Fig. 2 is a rear 'view of the same partly in section, Fig. 3 is an elevation partly in section in an inoperative position, Fig. 4 is av rear view of' the handle, Fig. 6 is a sectional view of the handle taken on the line 6-6, and Fig. '7 is a top view of the ironing portion with the handle removed.

M'y sadiron consists of a bottom plate 1 which is polished on the outside being used for pressing same, Fig. 5 is a detail view ot the hook on the eil, Stratford, Conn.

(ci. 21a-25) the work. It has a recess in its upperside for a heating element 2 of an ordinary construction. It may consist of a wire wound on an insulation plate made of somerefractory material, for instance, mica or asbestos. The heating element is placed between refractory insulation sheets 3 and 4. One end of the heating wire is attached to a therniostatic switch 6 from which a exible cord 7 extends to a socket 8 in a rear block 9. The other end of the heating wire is connected directly to the other terminal of the socket. A plug 10 of an ordinary construction engages the ,socket and has flexible leads' l1. The switch 6 has a regulatingphandle 12 extending through a metal cover 13. A post 14 is supported on the plate 1, and the cover 13 is clamped between this post and a hook 16.

The plate 1 is curved at the rear to facilitate its rolling over and is provided ,with raised lugs 17 with holes for screws 18. Thecover 13 also has similar lugs 19 for the screws 18. The block 9 has a central lug 20 fitting between the lugs with heat insulating washers 21 between them. A heat insulating bushing 22 is ttedinside of the lug 20 and is threaded inside for the screws 18. Any ordinary heat resisting material may be used for the washers. and bushing, such as bakelite, micarta, asbestos composition, etc. The screws are adjusted so that the block 9 can lswing freely, the lugs with the screws -iorming a hinge. A lug 15 on the block 9 limits the swinging or rotary movement of the block 9 by resting against the rear edge of the plate 1 in the extreme open position. Helical springs 23 tend to move the block 9 away from the plate 1. These springs are placed in metal tubes 24 closed at the end and slidably tted in holes25 in the block 9. A heatv insulating plate 26 is attached to the rear surface of the block 9 forming a resting surface or base for the` block when the latter is tilted backward and the iron 1 is raised as shown in Fig. 3. The block 9 has a handle frame 27 extending to lthe front of the iron. Metal shells 28 are attached tor the sides of the yframe with screws 29 forming a rounded handle. A rubber bag 30 is l100 placed inside of the hollow space 31 in the handle. The bag consists -of two halves joined together near the base block 9 by a short pipe or nipple 32. The bagis lled Withmer'cury 33. The rear end of the bag rests against a plate 34 pivotally mountled on a pin 35 and provided with a spring 36 tending rto keep the plate in a raised position as shown in Fig. 1. f

A locking arm 37 is placed Iunder the handle conforming to the latter with -its curvature. .I t

has a lug 38 at the rear end extending inside and rotatively mounted on the pin 35. A lug 39 limits the outward movement of the arm. The arm 37 has a channel-shaped section supporting a spring 5 40 which tends to push the arm away from the handle. The front end of the handle has a pawl 41 pivoted on a pin 42. A spring 43 tends to turn it outward keeping the lug 44 resting against the edge of the arm. The pawl is adapted to engage the hooi;V 16 when the arm 37 is held against the handle by the pressure of the users hand in direction of arrows 45. The lower side of the pawl is curved so that when the handle is pushed down, the pawl, striking the hook, becomes deflected and passes under the hook. Then the pawl straightens out again under action of the spring 43 and engages the hook 16 (its rear portion). The pawl releases the hook, however, when the arm 37 is free and moved out by its spring 40 as shown in Fig. 3. The end of the pawl with the arm 37 closed is shown in Fig. 3 with dotted lines.

A latch 46 is rotatively mounted on a pin 47 in the front end of the handle frame 27 and has a lug 48 engaged by a spring 49 tending to keep the latch closed against the front end of the handle. The end of the latch has a hook 50 adapted to engage the front end of the hook 16 which is provided with a slot 51 for that purpose. A fiat spoon-shaped lever 52 is placed in the front end of the handle under the mercury bag 30. Its free end has raised sides, and the front end is freely pivoted on the pin 47. The weight of the mercury tends to keep the lever 52 down and against the wall of the handle as shown with dotted linesin Fig. 3.

The latch or pawl 46 has a lug or pin 53 resting against the lever 52, so that when the latter lever is depressed by the weight of the mercury bag, the latch 46 is pushed out as shown in Fig. 3, the hook 50 disengaging the slot 51. The arm 37 has a lug or pin 54 resting against the lever 52 and tending to raise it when the arm is pressed against the handle. The latch 46 is released in this position and can engage the hook 16. The hook 50 has a tapered lower side and can slide over the hook 16.

The operation of my sadiron is as follows.

When the iron is in an operative position and the handle is held in the users hand, then the arm 37 is pressed against the handle, and the pawl 41 engages the hook 16. The lever 52 is raised by the pin 54 releasing the latch 46 which engages therefore the slot 51 under action of the spring 49. The mercury (or a similar movable weight) 33 flows into the handle, being also pushed by the plate 34 under action of its spring 36. The mercury in this position (Fig. 1) distributes the weight over the ironing plate 1 thereby facilitating the operation of the iron. The iron in this position can be carried, the handie retaining its engagement with the hook 16 by the hooks 4l and 50. The iron can be also tilted backward and left to rest on its back plate 26 (on the block 9). The mercury then flows down into the rear portion of the handle, deflecting the plate 34 and releasing the pressure on the lever 52. The latter in turn releases the pressure on the pin 53 of the latch 46. The hooks 41 and 50 remain therefore engaged with the hook 16 -even if the hand is subsequently removed from the handle leaving theiron to stand on its back plate and ready for use.

:The iron tilts itself automatically, however, if the grip on the handle is released while the iron still remains in its operative (horizontal)l position., As soon as the grip is released, the

Spring 40 will push the arm 37 out, releasing the pressure on the lever 52 and permitting the latter to drop under the weight of the mercuryk bag. The(lever 52 will then push the latch 46 out, releasing the hook 50 from the engagement with the hook 16. The handle with the block 9 will be then free to turn away from the plate 1 under action of the springs 23. With the arm 37 moved out, the hook 41 clears the end of the hook 16 as shown in Fig. 3, thereby permitting the block 9 to move away from the plate 1 to the limit determined by lug l5 resting against the rear edge of the plate 1 as shown in Fig. 3. The mercury will then ilow into the rear end of the bag 30 pushing out the plate 34. The combined weight of the mercury and the block 9 will then overbalance the plate 1 and will force it up in the air. The iron will be then resting on the insulated back side of the block 9 without any danger of burning the supporting surface or the work.

Ii' it is desired to use the iron again, then the handle must be taken in hand and pushed over until the released hooks 41 and 50 snap over the rear and front edges of the hook 16. The iron being then turned into the horizontal position, the mercury will return to the front portion of the bag.
