RUSSELL, OF UTICA, NEW YORK, ASSIGNOR TO SAVAGE ARMS CORPORA- TION, OF UTICA, NEW YORK, A CORPORATION OF DELAWARE IRONING MACHINE Application filed December 28, 1926. Serial No. 157,438. r

The object of the invention is the provision of a power driven, domestic type, ironerof slmplified and improved construction, capable of operation with a minimum of manual.

effort and constructed to permit of the assembly of the various parts in a compact and at tractive form as below pointed out.

In the accompanying drawings, Fig. 1 is a perspective view of the preferred form of the complete ironing machine unit,

Fig. 5. is a section on the line VV of Fig. 4, certain parts being omitted for clearness of zo illustration, and

Fig. 6 a view of the left-hand end of the machine.

Referring to Fig. 1, it will be, seen that the machine includes a. padded ironing roll 1 journalled at one end in the arm 2 of a goose neck support 3 and supported at its other means might be used. The shoe is carried by trunnions 9 in the arms 10 secured to the rock shaft 11. When the shoe is properly set with respectto the roll, rocking movement thereof on thearms 10 may be limited or prevented by any suitable means as for example by a screw, or any equivalent device, represented by 12 in Fig. 6. v

The rotation of the roll and the movement of the shoe are both produced by an electric motor 13 mountedat the rear of the transmission housing (Figs. 2 and 3) and the whole machine is preferably mounted on atable 14, which although shown as provided by spring 31.

with its own legs, may when: the legs are removed, be placed upon any other table or wherever is most convenient. The. motor armature shaft is directly coupled to the main drive shaft 15 which carries a worm 16. Referring first to the drive connections of the ironing roll, itwill be seen that the worm 16 drives worm-gear 17, secured to a shaft 18, which shaft carries free thereon a pinion 19 adapted to be clutched to or released from the shaft by means of the splined clutch collar 20 and clutch pins 21. ion 19 drives the large spur gear 22 fast on the end of the roll shaft 4, above. mentioned, and thus drives the ironing roll whenever the motor is in operation and the pinion 19 clutched to the shaft 18. The clutch 20-21 The pinis conveniently operated by means of any suitable clutch operating member such as the lever 23 (Figs. 1 and 5) pivotally mounted on the housing 5 and connected with the collar 20 by a'fork or any other suitable means as will be understood. lVhen the lever is moved to the right the clutch is opened I and it is closed by theopposite movement.

I Referring now to the shoe drivethe worm 16 also drives a worm gear 2lwhich is loosely mounted on a shaft 25 j-ournalled in the walls of the transmission housing. By means of the clutch pins 26 and a clutch collar 27 splined to the shaft 25 the latter may be clutched to or released from the gear 24. This clutch is of the automatic throw-out type and is so organized that when allowed to bedriven by the gear 2-l it will rotate the shaft through one hundred and eighty degrees only and will then of its own accord come to rest. This operation is conveniently effected by means of the face cam28 formed on the flanged part of the clutch collar 27 and adapted to engage a control pin 29 which is formed on or by the lower end of a plunger rod 30 mounted for vertical endwise move-.

mentin the outer wall of the transmission housing and normally urged downwardly hen the rod is elevated the pin 29 will be withdrawn from engagement with the cam 28 and the clutch collar urged by its spring 32 will move into clutching engagement with the gear 24. If the nlnnopr rod is held elevated the" drive of-sha ft 25 will be continuous, but if it is released the pin-29 will engage the peripheral surface of the flange of the clutch cam until the latter has rotated under it far enough to let it ride ofi? and drop to. its ,lowest'lposition where it -is engaged by the face of the cam. This.

occurs at the lowest portion 33 of the cam .face. Continued rotation of the shaft for a further quarter turn, with the pin now engaged by the cam face will result in the clutch collar being withdrawn from engagement with the gear 24' whereupon the shaft 25 will come'to rest and remain stationary- 7 until the rod is again elevated when the shaft 25 will again be rotated one hundred and eighty degrees and so on. Thus a momentary lifting of the plunger rod 30 pro- 'duces one half rotation of shaft 25. Re-

ferring to Fig. 2 it will be seen that the upper end ofthej rod 30 is connected to -a crank arm 34 fixed to the'trunnion 35 of the con.- trol board 6, .so that to procure a half turn of the shaft 25, at any time, it is merely. nec-' essary to depress momentarily the board 6.

The spring which elevates the plunger rod 31 serves to hold the control table inits normal horizontal position and maintains it in such position with sufiicient'rigidity to enable-itto serve as a work-support on which the garment can be arranged for presentation to the roll, and the table is wide. enough for this use. v

I These half turn movements of the shaft 25 are utilized to effect the'movement of the shoe toward and from the roll and to'this end, referring now to Figs. ,4 and 5, an cecentric 36 is s ecuredto' the end.of shaft 25 outside the transmission housing but within a suitable protecting casing and an eccentric rod extends rearwardly from theeccentric strap into operative engagement with a crank arm 37 secured to the rock shaft 11 or formed as an extension ,of the arm 10. In order that the'shoe may act yieldingly' on the roll, the-connection between the'eccentric component links normall v,rod and the crank arm includes a plunger member 38 which 0 erates against a spring 39 within a guide s eeve 40, the latter being rigidly connected to the arm 37. The end' of the spring 39 bears against an adjustable screw. stop as shown so that the ironing pressure ma bevaried to suit the conditions in hand. Furthermore, the eccentric, rod is articulated with'a toggle joint 41 with its in their deadcenter relation and beneat the joint is pivotall-y mounted a breaker member 42 operated by a push rod 43 slidably mounted on the transmission housing andhaving a conveniently located knob 44 at its up er end. This push rod is preferably locate right handend of the roll and somewhat adjacent the above the feed table, .and is normally urged upwardly by a spring 45 which tends to hold the breaker member away from the toggle, I

but should it be desirable at anytime to effeet the release of the shoe independently of its power drive, the operator is merely required to strike the knob which breaks the toggle and thereupon the shoe will fallwell away from the roll. This arrangement is primarily designed to prevent the burning or scorching of thepadding on the rollor of the article being ironed, should the current fail while the hot shoe is in pressing engageing of the shoe away fromthe roll facilitates cleaning and waxing of the shoe since when the toggle is broken, access may be readily.

had to every part of the ironing surface of the shoe. To return the parts to their normal positions the shoe may be manually restored to operative position by .means of a knob handle 46 (Figs. 1, 4 or 6) which projects from the left-hand end of the shoe. i Projecting from the rear of the transmis- -ment with the roll. In addition, this open- 7 sionhousing is a bracket 47 (Figs. 2 and 4) I which provides a pivotal support for an upper table top 48, thelatter being arranged to swing about the vertical post 49 and this permit said table top to be utilized whether or not the machine is in operation. In Fig.

,1 the machine is shown ready for use and the a I upper table top, supported by a collapsible leg 50, is .conveniently located at the right and of the machine for use in folding the articles to be ironed and, to hold the finished work, the drying rods 51 housed in holes in the end of the table top can be pulled out as shown when needed. When the ironing operation is completed the drying rods are pushedhome, the leg 50 collapsed and-the table top swung back over the machine to the position shown in dotted lines in Fig 1 where itprotects and conceals the ironing elements and where it may ofcourse be used as an ordinarytable. i

heated electrically and as shown inFig. 1, individual heating and motor switches are mounted on a swltch plate 52 conveniently located on the front of the transmission housing where they are readily accessible to the operator. l

Inoperating the machine flat work is arranged'substantially evenly of the length of As stated abovethe shoe is preferably the roll and then, with the motor switch in ened or guided, the upper'or leading edge of the shoe isprovided throughout its length with a strip of heat insulating material53' fected at the left-hand or open end of-theroll (Figs. 1 and 6), the goose-neck support at that end readily permitting the workrto .be set as required on the end of the roll or if the case of skirts or the like. Again, certain articlespleated skirts for examplemay require pressing in setforms necessary slipped right over the roll7sas in or arrangements. Articles of this nature are arranged on the roll'an'd then, with the roll drive clutch disengaged and consequently the roll stationary, the shoe is operated as before by a slight pressure on the control board.

When the article is sufliciently pressed theshoe is released by another slight'pressure on the control board, the roll manually rotated to advance the unpressed portion of the garment and the shoe again operated.
