Be it known that we, EUenNn'E. Non'ro v and ALBERT U. Lauonituccsn, both citizens of the United States, and residingin the city of Bridgeport, county of Falrfield, State of Connecticut, have invented certain new and useful Improvements inIron'ing- Machin and" we do declarethe following to be a full, clear, and exact description. of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to certain improvements in ironing machines but more particularly relates to machines of this description that are usedjcoiron surfaces by forward.

and backward movements of the iron.

Our invention has for its object to provide a very eiiicient machine of this nature and to make provisions whereby the pressure of the iron on the ironed surface shall be lessened at the ends of the forward and backward movements of the iron, purpose of shifting the oods beneath the iron or for the removal 0 the goods and the substitution of others.

With these ends in view our invention consists in certain details of construction and combination of parts'hereinafter fully set forth and then particularly ointed out in the claims which conclude t is description.

: In the accompanying drawing Figure 1 is v a side elevation of our improved machine-' Fig. 2 a front elevation-Fig'. 3 a broken detai side elevation of the cooperating parts which eflect the removal or elevation of the iron, and Fig. 4 a, detail broken section at the line to, w, of Fig. 1.

Similar numerals of parts in the several figures of the drawing.

1 is the bed of the machine and 2 the ironingboard or table mounted thereon and havas ing the upper cofiiers of its sides round shown at 3 for the purpose hereinafter to be explained.

- 4 is a standard secured to the bed and rising vert cally therefrom, andfi is abea'ring likewise bolted to the bed at]; distancefrom the standard, and within this bearing and standard is journaled the ower shaft 6 carrying the usual power pu leys 7,

diametrically and - disk. either for themeshes with a comparative y l'ar the spur gear shafts s4, 35, reference denote like angle portion at 8. Se- '--an cured to the extremity of said shaft remote which has an i this disk, and

this way 12 is the iron of any suitable and approved structure which is adapted to be heated in any ordinary manner, and 13 is a rod one extremity of which ispivoted at 14'to an extension 15 the iron, while the other end of said rod is pivoted around a stud 16 that extends from the block 11, the latter being secured in any adjustment along the way 10 in the usual manner as by a nut-l'lld'riven around said stud. Y

From the above description it will be readily understood that as the disk- 9 re: volves the rod 13 will act as a crank rod and will cause the iron to be moved forward and backward across the board 2 this forward and-backward movement being limited according to the normal distance ofthe block 11 from Rigid on the shaftfi is gear 18 which meshes with a spur gear 19 rigid on a short shaft 20 that is journaled to the'stand: ard' 4., and rigid on the other extremity of and normally adapted to slide -freely therein.

the axial center of rotation of said that is securedjto the top of.

tut

this short shaft 20 is af's ur gear 21 that i e idle spur gear 22 on theshort shaft-'28 t at is supported by said standard. a

24, 25, are-arcuate slots within the standard and through shafts 26, 27, and loose on these" shafts are spur gears 28, 29, which are in mesh with 22, said short shafts being secured in. any adjustment throughout said slots by means of nuts 30, 31.

32, 33, are spur gears supported by short that are capable of adjustment throughout arcuate 'slots 36, 37 within this standard 4, this adjustment being effected inthe usual manner by the manipulation of nuts 38, 39. Rigidwith the gears 32,

are cams 4:0, 4 1, and

will likewise revolve through the medium of the gears 18, 19, 21, 22, 28, and 29.

42 is a bell crank lever pivoted at its the top of the standard 4 carrying at its lower end a roll 43, and 44 isfa; rod whose extremities are pivotedrespectivelyto t heextension 15, and to the upper extremity of the bell crank 42.

-The operation of our improvement is as 1 f l t s pp w t fl es W b said gears mesh'with the spur gears 28, 29, so that it will be readily understood that asthe disk 9 re- -volves, the gears 32, 33', and the cams 40, 41,

volved in the direction tially aswshown-at Fig. 3, and the iron will th'n be attheend of its inward stroke, and

meanwhile the cam 40 will have been brought into position against the roll 43 so that the continued movement of said cam will force the'lower end of the bell crank still farther forward, thereby causing the iron to be elevated. As the cam 40 continues 'to revolve it will leave the roll 43, whereupon {the iron will descend and again be supported by the ironing board. On the return movement of the iron caused by the revolution of the disk 9 said iron will be moved towardthe other end of the ironing board until'it reaches the extremity of its movement, and this will cause the lower end ofthe bell crank lever to be thrown in a direction opposite to that shown at Fig. 3, so that the cam 41 in its revolution will strike against the roll 43 and throw said end forwardlikewise effecting the elevation of the iron, and when this cam has passed the roll-the iron, will descend and rest upon the ironing board as in the first instance, and thls operation w1ll continue as the disk 9 contlnues to revolve unless some means is v employed to hold the lower end'of the bell crank so that it can not be swung back after contact with the cams 40, 41, has ceased.

It is sometimes advantageous to hold the lower end'of the bell crank so that the iron may have its forward and backward movements withoutany cont-act withthe ironing board, as in the instance of goods whose removal from and placement on the ironing board consumes more or less time, and therefore we have provided certain means for accomplishing this purpose which we will now describe.

45 is a collar that extends through an arcuate slot 46 in the standardand is'adjustable therealong and may be secured in any desired adjustment by the manipulation of the nut 47. Loosely extending through this collar is a bolt 48. 49 is a vertically disposed rod and 50 are-links-whose upper extremities are pivoted respectively to the heel end of the bolt 48 and to a bracket 51 that extends from the top of the standardwhile therlower extremities of these links are pivoted to the upper end of the rod 49. When the rod is moved upwardly the bolt will be projected and when this rod is moved downwardly the bolt will be withdrawn. After the'lower extremity of the bell crank has been thrown sufficiently forward, either by the inward movement of the iron or by the action of the cam 40, the rod 49 is thrust upwardly thus causing the bolt 48 to be projectod behind the bell crank, as shown in provided which blocks at all Fig. 3, thereby enabling the iron to be held in elevation at the end of its rearward stroke, in which position it is farthest from the operator. In order to prevent any accidental throw of the bolt a lateral extension 52 from the lower leg of the bell crank is times the locking action of the bolt except when the bell crank is in the position above described.

.In the drawing, Fig. 1, the parts are adjusted for substantially the greatest movement of the crank rod 13 and consequently the iron 12, but in case a shorter throw or movement is desired, the block 11 is merely adjusted to a position nearer the axis of rotation ofthe disk 9, and this will cause the lower leg of the bell crank to reciprocate in a shorter arc, thereby rendering it necessary to adjust the spur gears 28, 29, outwardly through the- slots 24, 25,

and to adjust the gears 32, 33, with their cams 40, 41, inwardly through the slots 36, 37, so that said cams will properly engage the roll 43 at the proper times. This shortening of the stroke of the iron will also render it necessary to adjust the collar 45 inwardly in the slot 46 so that the bolt 48 may be able to lock the bell crank at the end of its limited forward throw. These adjustments, however, are mere mechanical expedients that are no part whatsoever of our invention.

We prefer that the pressure of the iron against the goods to. be ironed shall be somewhat increased without adding to the weight of the iron itself and at the same time it is desirable that this pressure shall be yielding, and. we have therefore provided certain means to bring this result about which we will now describe. I

53 is a yoke which at its middle portion extends beneath the crank rod 13 and is secured thereto by means of a clip 54 placed over said rod and fastened to the yoke on opposite sides of the rod, as clearly shown at Fig. 4. From the extremities of this yoke depend pins 55 and coil springs 56 are provided whose extremities are secured respectively to the lower ends of these pins and to the bed 1, so that it will be clear that the pressure of the iron will not only be increased but will be rendered resilient or yielding.

It will of course be readily understood that the degree to which the iron is elevated depends upon the action of the cams 40, 41, against the roll 43, and it will be clear that a shortening of the lower leg of the bell crank or of the cams themselves will bring about a decreased final throw of said leg so that it is possible merely to lessen the pressure of the iron against the surface to be ironed, and we therefore do not wish to be limited in this respect.

We prefer to round the side edges of the reference being had to beneath the iron, and for the further purpose of taking care of parts that have more or less fullness.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. In a machine of the character described, the combination ofan iron, means for moving the iron in a plane forward and backward across the surface to be ironed,
