STAND FOR HEATING ELECTRIC SADIRONS.

Application led January 28, 1928. Serial No. 250,151.

flanges 26. Each shelf 23 is provided with My invention relates to a stand for heating electric sad irons.

The essential objects of my invention are to prevent personal injury by shock; to insure against fire; to preventwaste of current on the way to the stand; to accommodate a plurality of irons simultaneously; and to attain these ends in a structure of maximum simplicity and of inexpensive construction.

To the above ends primarily, but not exclusively, my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification Figure 1 is a front elevation of my stand showing in broken lines a -second position of the iron,

Figure 2, a plan view of the same with a portion of the upper floor or shelf` broken away,

Figure 3, a section of the stand'taken on line 3--3 of Figure 2,

Figure 4, an enlarged fragmentary plan view of the cooperating insulating members, and

Figure 5, a partially diagrammatic view of the electrical connections.

Like reference characters indicate like parts throughout the views.

In detail my stand comprises a floor or base 8, a rear wall 9 attached by a flange 10 and rivets 11 to the base, sidewalls 12 also attached to the vase by flanges 13 and rivets 14, and to theA rear wall by rivets 15 engaging flanges 16 upon the latter wall. The top edges of the side walls are inclined downwardly and rearwardly. Midway between the side walls is a vertical partition 17, of the same height and top contour as the side walls, fixed to the base by flanges 18 and rivets 19, and extending from the front thereof nearly to the rear wall, thus dividing the stand into two equal compartments. The latter are each transversely divided by a downwardly and rearwardly inclined thin metal shelf 20 extending to the back wall 9, lying in a common transverse plane, and attached tothe adjacent wall and partition by rivets 21 passing through lateral flanges 22 interval with the shelf. 4

Parallel with the described lower shelves are upper shelves 23 of like material, extending to the rear wall, each in the same transverse' plane, and each attached to the adjacent wall and partition' by rivets 25A inl lateral a central open longitudinal slot 28 extending nearly to the rear wall. Thus are formed upon each side of the partition 17 a lowermost compartment 31, an' intermediate heatlng compartment 32, andl a storage compartment 33.

Mounted in the rear portion of the stand and extending completely across the compartments32 is an abutment block 36 of insulating material inclined upwardly and forwardly from the rear wall 9 to which its rear edge is attached by screws 38. Its side edges are engaged to the walls 12 by screws 40. Midway its forward edge the plate is pro- ,vided with a slot 41 to frictionally receive the rear end of the partition. At each side of the partition the block is provided in its forward end with angular V shaped recesses 43 and 44 respectively forming resultant inclined abutment faces 45. The rear corners of the plate are diagonally cut away forming right angular recesses 47 between the block and the corners of the stand." Centrally of its length theblock is provided. in its rear edge with an angular V shaped recess 49.

At opposite points in each of the recesses 43 and 44 oblong plates 51 and 52 and 53 and 54 respectively are fixed to the abutment faces by attaching screws 56. Metal rods 59, 60, 61 and 62 through the block 36 communicate respectively with the plates 51, 52. 53, and 54 to which they are severally disposed at right angles. Each rod terminatesI at its forward end with an undercut screw head portion 65 seated in a tapering perforation 66 in its plate, while the rear end portion of the rod is provided with a thread 68 to receive a nut adapted when turned to maintainl the head portion 65 of the rod in its seat 66 flush with the face of the plate. The nuts are herein identified respectively by the numerals 70, 71, 72 and'73.

Insulated electrical wires or conductors 75 and 76 extend from a socket 77, or from a source of electrical current, through a hole 78 in the side wall of the stand. The conductor 75 is first clamped to the rod 59 by the nut 70, and extends thence to the rod 61 where it is clamped by the nut 72. `The conductor 75 is engaged with the rod -60 by its nut 71 and isnext engaged with the'rod 62 by the nut 731 The described elements 'of my stand are ried by an electrical sad iron. In the draw-- ings 80 represents the body of such an iron with its handle 81. In the topl of the body near its end are-seated the vertically projecting rearwardly inclined contact or terminal plugs 83 which form the means for connecting the iron to an electric circuit. The heating unit of the sad iron may be of any usual construction. In Figure 5 at the left is diagrammatically shown the core 85 and its iwound heating wire or wires 86 electrically .clination of both blocks is the same. Fixed to the faces 97 by screws 98 or otherwise are metal plates 99 provided centrally with holes 100 to receive the outer ends of headless contact screws 101 threaded in bushings 105 frictionally seated in holes 106 in the block 96. The inner ends of the screws 101 yengage the plugs 83, while their outer ends,

which are iush with the plate 99 are adapt- I ed to contact with the head portions 65 of the rods in the abutmentv block 36. The faces of the plates 99 likewise are adapted to contact with the faces of the adjacent abutment plates 51,k as best seen in- Figure 4.

In utilizing my invention the lower compartments 32 are for heating urposes and permit the simultaneous heatlng of two irons. The latter rest upon the shelves 20 y W'iththeir handles projecting through the slots 28. If one of the Hats is not in 1mmediate use lit may rest upon a shelf 23l in one of the upper compartments as shown in broken lines in Figure 1'. The blocks 96 are readily applied to the terminal plugs of irons and are detachable for use upon awsecond iron. When inserting an iron in a lower compartment the inclination of the floor A20 not only automatically induces the ,iron

downwardly and rearwardly, as' is Itrue of oors 23, but by gravity maintains the metallic electrical contact elements of both.

blocks 36 and 96 in intimate en agement with each other. This intimacy o engagement is also increased by the lateral inclination of the faces lof the recesses of the abutment, and the laterally inclined faces of the blocks 96. The use of contact screws 101 in threaded connection with bushings 105 maintains an exceptionally intimate electrical connection between the screws and the adjacent electrical conductors.

In the diagram of the electrical circuits,

Figure 5, when the Iiron is positioned as y shown in broken lines at the left, the current passes through conductor 75, rod 59, the adjacent cont- act plates 51 and 99, contact screw 101, plug 83, wire 86, core 85, to the second contact plug, screw, contact plates, and rod 60, and thence back through Wire 76. When an additional ironis positioned as shown in broken lines at the right in Figure 5, the` current passes through the conductor 75, plug 90 and intervening plates and screw, next through the core 92, wire 93, second plug 90, rod 62, and intervening metallic elements, and thence out through line 76. The circuits are arranged in multiple or parallel rather than in series.
