` InoNINGsMnoHINE.

Beit known that I, CYRUS lM. APPLEGET, a citizen ofthe -United States, residing at North lYakima, in t-he county of Yakima and State of Washington, have invented certain new,and useful `Improvements in Ironing- Machines, of which` the followingis a speciication.

My invention .relates to .improvements inironing machines in which an iron is caused to move 'over "a stationary or adjustable ironing table; and the objects ofmy nvention are, first, to start and stop the operation of the ironing machine by means of a treadlel operated by one foot';second, to lower and raise the iron vfrom the' ironing table, .and also to re,'gulatet hev pressure of the iron on the ironing table by means of the' pressure brought to" bear on the. above-mentioned 2o treadle; thirdfto control the length of,l the stroke of the iron'y overl` the4 ironing table by means of the pressure brought to bear on asecond'treadle, operated by the .other fQot; fourth, to adjust-the time the iron starts moving over the ironing table to the height of the iron above said table, orlthe pres-sure of the `iron bearingon said table, by adjusting the length pf a pitm'an operating a clutch for starting and `stopping the machine; fifth, to adjust theironing table horizont-ally under the` iron, by pivot-ing the arm which carries it so that the table can be moved in a radius around said pivot.; and, sixth, to adjust the direction in which the iron points by means of a construction and arrangement o f parts to be hereinafter described, I attain these objects by the mecha- Anism illustrated in the accompanying drawchine with the supporting frame, rocker, and spring shown in Fig. .6 removed; Fi 2 is a top view ofthe machine, showing 1t complete with the exception of the ironing' table, which latter is no part of the present invention; Fig. 3 is a plan and sect-ionen the line C-D of Fig. 1; Fig. 4 is a plan and of the machine removed from Fig. 1; Fig.` 7 v shows two views of the ptman to be hereinafter described; and Fig. 8 is a sectional View showing the connection iron and the rack-bar.`

Referring specifically to the drawings', the framework of the machine is in two parts,

lfand 2, part 2 differing from ypart 1 in that the arm supporting a shaft 4 is set out to have -room for the drive pulley 5 of 'said shaft. The sections of the frame have bases laand 2, respectively, with bolt .holes 3 for securing to the floor the frame proper; and the guards 1b and 2b. Connecting and eX- tending between the two arms offrame 1 and"2',` which act as bearings, is theshaft 4 on whichturns the loose pulley 5, in which operates a friction clutch member 6, its obratend Dec. 1o, [1912."

ject being to startand stop the operation of the machine. r

Supported by the shaft 4, and secured to it, is aneccentric 7 which works in conjunction wit-h the friction clutch memberfi, the latter being forced over in contact-with the clutchrim of the .pulley 5 by an incline 8 on one side of the pitman 9, shown more clearly in Fig. 7.- The movement of the pitman 9 along its length in the direction of the connection 36, causes the incline 8 to push against the turned projection 10 on theclutch-member 6, thus forcing the latter over in contact with the clutch rim ofthe pulley15, and setting the machine in motion.

The operation of the pitman 9 will be here- Connecting the yframes 1 and 2', vand ex tendin between them, is ashaft 16A which is the earing for a lever17 having atA one Figure l is a side elevation of the ma-v of its ends a sector gear 17?. The other end of the lever has a slot whichforms the guide 15 in which the slide 14 moves.A Within the guide slot 15, and connected .to-.the lower end of the lever-17 and to the'slide 14, is a coiled spring 18 which tends to hold the slide 14 near the upper end of the guide'- slot 15, unless counteracted by tension on4 a chain, or other connection, 19,which connects the arm 12 to a-vtreadle 20l mounted `on the base 1n. 1 y

Into the teeth ofthe sector gear 17a `are .meshed the teeth of a nrack bar 21, carrying the iron 26 yto be hereinafter described, saidl i described... t 'Ilie rack bar 21 is held in contact y' with the sector gear from above by'rollers 24 which'fturn-on pins .25 th'at extend be- "tween 'and' connect the'f'two rocker arms.

The rollers and the sector gear .1,7a also serve to hold the bar, 21 in thesame tangential line 'with respect to the axis of the hrockers 22 and-23.'

. In the mechanismabove described-the action is as follows: The shaft 4A `rrotates the eccentric 7 which causes a reciprocating motion of the arm 12. This reciprocating m9- tion is'transrnitted yto the lever 1 7 by the pin .13, and the block 14,- thus-causing the leve-r 17ito swing on its pivot and through the. sector gear reciprocating the` rack bar 21,

16now bein longer, the sector gearand the lever 17 will thus swing through a smaller -arc of a circle, causing the stroke of the-iron `26 to be shorter. Hence, the length of stroke of the iron 26 is regulated by the ressure brought to bear on the treadle 20. v olted between the two part-s of frame 1 and by bolts 27, is va bearing 28, carrying the "ironing tablel arm 29, which arm can thus be moved in a radius about the bearing 28. To the arm 29 is secured an ironing table 30, with a guard 31 for keeping goods from the machine. The ironing table 30 forms nopart of the present invention. Pivoted on the shaft 16, which passes through them, aretheroc'kers 22 and 23 before mentioned,

leach having an arm to which a chain, or

other connection, 32 is attached. The chain 32 passes-over a suitable pulley 33 and is connected to a treadle 3 4 mounted on-the base 2. On pressure being applied to the treadle 34, the rockers 22 and 23 areswung together on their pivots, which tilts the rack bar 21 about the shaft 16, thus bringing the iron 26 down on the ironing table 30, the

' pressure of the iron on the table being determined by the pressure on the treadle 34. When the pressure on the treadle 34 is Ireleased, the iron is'lifted from the ironing table by the rockers being swung back around theshaft 16 through the medium of springs 35 attached to a lug on each rocker i below. '6o

`.lengthening and shortening it.

and to a corresponding lug on the frame (See Figspl and 6.) Connected to the rocker 23, by a lpin 36, is the pitman 9, the latter having an adjustment 38, for See Fig.

7.) -When the rocker 23 is swung y means of pressure on the treadle 34, as'previously eXp amed, the pitman 9 1s caused to move in conjunction with therocker, whichl causes t-he incline 8 on the pitman to move the clutch member over in contact with the 'clutch 4rimof the .pulley 5, as reviousl exthe pit-mami) must always move in conjunci tion witheach' other, and since a certain position of the incline 8 on the itman 9 Aagainst the clutchv member 6 wil always throw the` machine in mot-ion, the machine will always startwhen theI iron 26 is brought 'to within a ixeddistance of the table top 30. By` means .of the adjustment 38, the relative height of the iron 26 above the ironing table 30, with respectbto the starting position vofthe -.in cline\8, can be varied; hence, the height vvof the' iron 26 above the ironing table 30 for the Starting position can be varied,l by means of. the adjustment 38. Supporting the iron 26 is a shank 39 which canbemoved around the pivt 40 with a part 39a of the shank 39 extending up through an -arcuate slot 40 in the rack bar 21 (see Fig. 2). To the'upper end of the shank is attached a handle 41 by a pivot pin 42.A Thus the handle 41 can be moved in a vertical plane about the pin 42 and b the eccentric placing of .said pin in the en of the handle,'the latter forms a clamp for holding the shank stationary when in-the position shown in Figs. 1 and'2.
