IRONER.

Application led March 14, A1927. Serial No.'175,180.

It is well known that very little effort is required to move a hot sadiron over an object being ironed, but it isveryy laborious worktohft the sadiron and carry the same from the work to a supporting stand and from said stand to the work.

By the use of my invention, this laborious work is eliminated and said invention also `provides power means for imparting the to and fro movements to a sadiron.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. f

The numeral 14 indicates an ironing table, the top 15 of which affords a smooth flat ironing surface. This table top 15 at its rear end has a turnable section 16 pivotally mounted on a heavy bracket 17V on said table .top for horizontal swinging movement in the plane of said table top.v The joint between the tabletop 15 and its turnable section 16 is on the arc of a circle, the center of which is at the axis of the pivot of said section.

The numeral 18 indicates a heavy electric sadiron of any suitable type and has a longitudinally extended tubular handle 19 rigidly secured toa heavy core in the form of a rod 20, the end portions of which, outwardof said handle, are journaled in a pair of upstanding ears 21 on a plate 22 rigidly secured to the top of the sadiron 18. Headed screws 23 applied to the ends of the rod 20 hold said rod in the ears 21 against endwise removal therefrom with the handle 19 closely positioned between said ears'with' freedom for turning movement about .the axis of said rod.

To support the sadiron 18 out of Contact with the table top 15 when not inl use, there is provided a pair of laterally spaced lazy tongs 24. These lazy tongs 24 are connected at their intermediate joints and held laterally spaced by horizontal rods' 25, the ends of which afford the pivots for said joints.

These lazy tongs 24, at their rear ends, are l mounted in a pair of latterally spaced stand-- ards 26 onthe turnable table top section 16. The upper rearmost links in the lazy tongs 24 are pivoted to a shaft 27 mounted on the standards 26 and have vformed therewith in bell-crank arrangement rearwardly extended arms 28 for a purpose that will presently appear. The lower rearmost links in the lazy togs 24 are yattached to the standards 26 below the shaft 27 for compound pivotal and verticalV sliding movements in vertical slots formed in said standards.

The sadiron 18 is attached by a heavy hinge 29 to the front ends of the lazy tongs 24 for free ironing action on the table top 15, and for longitudinal tilting movement on p its heel into a raised position in which it is supported from said lazy tongs above lthe table top for free swinging movement there-` over. i This hinge 29 includes a rearwardly extended horizontal hinge plate 3() on the heel of the sadiron 18, a wide oblique hinge plate 31 attached to the front rod 25, and a horizontal pintle 32 connecting said plates. The hinge plate 30 is mounted in a recess 33 in the heel of the sadiron 18 and is pivoted to said iron at 34 to permit horizontal angular movements of the sadiron 18 on the table top in respect to the hinge 29.

To hold the hinge plate 31 from turning on the rod to which it is attached and in a rearwardly inclined position from the pintleV 32, there is rigidly secured to the back of said plate a horizontal rearwardly extended rod 35 endvvise slidably mounted in an apertured depending ear 36 on one` of the rods 25. Obviously, this rod 35 holds .the hinge plate 31 for parallel movements and holding the same raised, as shown in Fig. 4, so that the sadiron 18 is out of contact with the table top 15 and may be freely swung over the surface thereof, there is provided a coiled spring 37 and a toggleV lever 38 mounted between the prongs of thebifurcated lower end portion of the hinge plate 31. The lower arm 39 of the toggle lever 38 is integrally formed with the hinge plate 30 at the pintle 32 and is in bell-crank arrangement with said plate. The other or upper arm 40 of the'toggle lever 38 comprises telescopically connected members, the outer of which is pivoted at 41 to the hinge plate 31. Y Y

The coiled` spring 37 encircles the toggle arm 40fand` is compressed between upper and lower Washers 42 on the members of said toggle arm 40, at the opposite ends thereof. When the sadiron 18 is supported on the table top 15 for ironing action, the members of the toggle lever 38 are straight and the spring 37 is held compressed between the Washers 42, as best shown in Fig. 8. To raise the sadiron` 18, the operator by meansV of the handle 19, slightly tilts said sadiron on the pintle 32 to move the toggle lever 38 beyond a. dead vcenter and thereby release the spring 37 so that it will exert a force sufficient to tilt the sadiron 18'to a tongs 24 will be alternately buckled and straightened during the ironing action. The pivot 34 also ,permits the sadiron 18 to be angularly moved to direct its point over the article being ironed. `Said sadiron 18 may also be moved laterally in either direction over the table top 15 due to the fact that the lazy tongs 24 are attached to the turnable table top section 16, which will be swung by said lazy tongs under the lateral movement of said sadiron.

lVhen the operator is through ironing, it is only necessary to lift the front end, of the sadiron 18 from the table top 15 to move the toggle lever 38 beyond a dead center to release the spring 37 and thereby cause the same to lift the sadiron 18 so that the same is out of contact with said ltop and may be swung into a position at one side of the table top 15 Where it is out of the Way.

Obviously, the connections to the sadiron F18 fromthe turnable table-top section 16 permit universal movement of AVthe sadiroxr 18 on the table top 15 so that all classes and kinds of ironing may be accomplished in To mechanically impart the to and fro movements to the sadiron 1-8 during the ironing action thereof, by oscillating the arms i Y 28 and thereby imparting the straightening and buckling movements to the lazy tongs 24, there is mounted on the table top section 16 an electric motor 43 having on its armature shaft a -Worm 44 which meshes with a gear 45 on a horizontal longitudinally extended shaft 46 journaled in bearings 47 on said section. On the shaft 46 is a Worm 48 which meshes with al gear 49 on a transing roller stud 57 which extends through aslot 58`in the front end portions of the arms 28 which are drawn together, as shown in Fig. 3.V The rack 56 works in a long depending sleeve bearing 59 on the under side of the table top section 16and a roller 60 engages the back of the Vrack 56 and holds the same forstraight line movement and in mesh with the gear 55. This roller 60 is journaled on a stud on a bearing bracket 61 secured to the table top section 16.

When the peripheral friction Wheel 52 is lill at the axis of the face friction Wheel 51, the driving connections from the motor 43 to the arms 2S is idle. By shifting the peripheral friction wheel 52 to one side of the axis of the face friction Wheel 51, the driving connections from the motor f3 Will be op-` erated to straighten the lazy tongs 24 and impart a forward movement to the sadiron 18, and by shifting said friction Wheel 52 to the other side of said axis, said connections Will be operated to buckle the lazy tongs`24 and thereby impart a backward movement to said iron 1S.

To shift the peripheral friction Whee'l 52 on the face friction Wheel 51, the turnable handle 19 of the sadiron 18 is provided 'with a segmental gear 62 which is secured to the rear end of the rod 20 for oscillatory movement transversely of the sadiron 18. This segmental gear 62 meshes -With a pinion 63 on a rearwardly inclined tubular shaft section 6%, the lower end of which is journaled in asleeve bearing G5 on the top of said iron 18 at the heel thereof. A shaft section 66 is telescoped into the shaft section Gli, and is square in cross section to connect said VtWo shaft sections for common rotation With freedom for endwise movement in respect to each other.

The shaft section 66 is connected by a universal joint 67 to the forward end of a horizontal shaft section 68 which extends through aligned apertures in the rods 25 With freedom for endwise movement, and its rear end portion is telescoped into a tubular shaft section 69, the rear end of which is ournaled in a bearing ZO on a bearing bracket 71 secured to the table top section 16. 'lhe shaft section 68, Within the shaft section 69, is a square in cross section and connects said

shaft sections

68 and 69 for common rotation. On the rear end of the shaft section 69 is a Worm 72 Which meshes with a Worm gear 73 journaled on the bearing bracket 71 and is provided with a crank-acting shipper arm 74 having pivoted thereto ar loop-like link Z5 mounted in the annular channel of a shipper collar 76 on the peripheral friction Wheel 52. c

Obviously, the link 75 is free to move transversely of the shipper collar 76 during the oscillatory movements of the shipper arm 74. From the above description, it is evident that y turning` the handle 19, the peripheral friction vWheel 52 may be moved axially on the shaft 53.

The length of the to and fro movements imparted to the sadiron 18 from the motor 43 is controlled by the operator While guiding said sadiron simply by turning the handle 19 to move the peripheral friction Wheel 52 over the face friction Wheel 53.
