The invention relates to ironing machines and more particularly to that type inv wh ch a flateiron is reciprocated over a fixed table under control of the operator.

7 One object of the invention is to provide a machine of this type, with improved n ech anis n jfor reciprocating. an iron, which comprise-sthe electric motorwhich travels with the ron- Another object isto provide improved res ciprocating mechanism in which simplereversible gearing is used. r

- Another ob'ect of the invention is to provide a machine of this character which is simple in construction and is readily accessible. r p e Other objects of the invention will appear from-the detailed description.

The invention consitj'n the several novel features hereinafter set forth and more particularly defined by the claims at the conclusion hereof. t

In the drawings: Fig. 1 is a perspective of a machine embodying the invention. Fig, 2 is a'vertical section through the reversible gearing. Fig. 8 is a detail section, showing the iron-lifting device- Fig, 4 is a plan view, the motor being removed- Fig.5 is a section taken on line 5-5 of Fig. 2. Fig. 6 is a section taken on line 66 of Fig. 4;.

The invention is exemplified in astrue turecomprising a supporti g f m wh ch is built up of sides 10, a longitudinal me ns ber 11 and'a plate having a horizontal portion forming a base 13 and a vertical por tion 1 iforming a back, all of which are rigidly secured together in suitable manner, to form a rigid supporting structure. An ironing-board orv table 15 is supported in an elevated position by a standard 16 adjacent one end, which is provided with an angular extension 17,to support the other end, so that garments may he slipped over the table. The ironing-table is usually usually electrically, in a mannerwellunderstood injt'he art. a flat-iron 18, usually of sufficient weight to produce the necessary pressure for ironing, is reciprocable horizontallyover the table 15 and is suspended by a universal joint 19 from an arm 2O, this joint permitting the necessary freedom of movement. of theiron to cause it to adapt its position to the material being ironed.

Arm 20 is formed on a carriage-24 which is provided with circular bearings 21 and 22 which are adapted to slide and rock on a shaft 23 which, extends longitudinally across the back of. the frame and isfilxedly secured in sides 10 of the supporting frame;

The mechanism for reciprocating the car- 7 hwh of the riage comprises an electric motor 25 is, fixed to a bracket 26 at theback carr age and s-movable therewith.

shaft '2Tof the motor extends downwardly through a gear-housing 28 formedonthe V carriage, to drive a pinion 29 which meshes with atoothed rack 30 formed on the upper portion of the stationary sha ft 23., Pinion 29 enclosed in a pocket 31 formed at therear operate reversible gearing and of the carriage, and is fixed to a shaft 32 t which is journalled inabearing formed in the back of the housing 28. A bevelled. friction pulley {E lis keyed to the front endof the shaft and engages with an upper bevelled friction pulley 35 and a lower bevelled friction pulley 36, so that pulley 34, shaft- 82 and pinion 29 may be driven in opposite directions to correspondingly shift thecarriage and the flat-iron. and 36 are loosely mounted on the motor shaft 27, movement in the housing 28 by a collar 39.

A clutchscollar lQis slidable on, shaft 27 between pulleys 35, 86 and is splined to said Pulleys 3 5 and each is confined against axial shaft, so that it willrotate therewith in anyposition of the collar. This collar is provided with clutch-teeth ll to engage cor responding teeth 42 on pulley 35 to drive the pinion 2 9 in one direction, and with oppositely facing clutch-teeth d3, adapted to interlock with clutch teeth 14 on pulley 36 to drive the pinion 29 in the opposite direction. The collar to is movable into neutralp osie ion between pulleys 35, 36, so that the re versible gearing will be inoperative by the shaft 27 This exemplifies reversible gearing for driving the pinion 29 to cause the carriage and the fiat iron to move in oppoite directionswithin therange provided for.

' which are disposed adjacent the frame-side rear end of said shaft. Said cam has a groove to shift and hold a lever 56 which is pivotally supported by a shaft 57 which is mounted in the housing 28 and is provided with a fork 58 which has studs 59 extending into an annular groove 60 in clutch collar 44 and whereby the collar may be shifted and held while it is rotating. The groove in the rear face of cam 55 has a concentric portion 55 adapted to hold lever 58 in its neutral position, a portion 55, adapted to hold the lever so the clutch-collar will be locked to drive wheel 36 to rotate pinion 29 in one direction, a portion 55 adapted to hold the clutch-lever so the collar will be lockedto drive wheel to rotate the pinion 29 in the opposite direction, and inclined portions between said holding portions, whereby the clutch -leverwill be shifted from neutral to either of its other positions and vice versa. This exemplifies a clutch-controlling device for the reversible gearing which is mounted on the iron carriage and which may be conveniently manipulated to control the movement of the iron from any point within its range of travel. To automatically shift the clutch collar when the iron reaches the end of its stroke in either direction, a slide 62 is slidably held by screws 63 on top of the carriage and is formed with a longitudinal slot 64 to permit limited movement of the slide relatively to the carriage. This slide is provided at its front with depending lugs 65 and 66 which are adapted to engage a stud 67 formed on cam 55 and at its rear with lugs 68 and 69'which are adapted to engage the hubs of arms 70 respectively 10. When the iron is travelling to the left,

i as the result of the shift of the handle in the same direction, stud 67 will engage lug 66 and shift the slide to the left, so that, as

I it approaches the end of its stroke, lug 69 will strike arm 70 until the cam has been shifted into its neutral position, whereupon wheel 85 will become idle, so that the iron will stop. When the iron is travelling to the right, as the result of the movement of the handle 45 in the same direction, lug 68 will engage the arm 70 at the right side of the machine as the carriage approaches the end of its stroke to shift lever 57 to operate the clutch-member 40 into neutral position and thus disconnect the driving connection for wheel 86, so that the iron will stop. This exemplifies means for automatically shifting a clutch for controlling the reversible gearing to stop the carriage at the end of its stroke.

Carriage 20 is preferably formed of sections 249, 2 t which are removably secured together by bolts 24, to permit the reverse gearing to be conveniently assembled and to provide access thereto whenever desired.

The housing 28 is adapted to contain lubricant for the gearing. A switch 84, for controlling the motor, may be mounted at any convenient point. Current will be supplied to the motor 25 through a flexible cord which maintains a connection between the motor and a source of current when the iron is in any of its positions.

In practice, it is frequently desirable to lift the iron over obstructions, such as buttons, on the material being ironed, without stopping the iron. To permit this to be done, provision is made whereby the operator may manually and readily lift the iron off the work and lower it; The carriage 24 is free to rock on shaft 23 for this purpose. A roller 71 is mounted on the lower end of a fork 72 projecting downwardly from the carriage. This roller is adapted to be shifted by an angle-bar 73 which extends longitudinally across the back of the frame and is pivotally suspended at its ends by arms 70 which are hung on shaft 23. Angle-bar 73 is provided with a roller 74 which is adapted to be engaged by a cam 75 on the upper end of a rod 76 which is mounted to slide vertically in guides 77. A lever 78, which is fulcrumed to the base of the frame at 79, and pivoted at 81to rod 76 is provided at its front end with a pedal 80, by which cam 75 may be shifted at the will of the operator. A spring 81 is applied to normally hold the cam in its inoperative position. When the iron is in its working position, roller 71 will be disengaged from angle bar 73, so that the weight of the iron will be applied to the work. lVhen the pedal 80 is depressed while the iron is in any of its positions, cam 7 5 will swing the angle bar 68 forwardly to swing the carriage to lift the arm 20 upwardly and lift the iron off the work. WVhen the pedalis released, the iron will drop back onto the work. Thus, the operator may read ily lift the iron off an obstruction without stopping the movement of the iron. The teeth of rack 30 are formed to permit slight relative shift of the pinion 29 without disengaging the pinion from the rack. The range of movement of the iron to the rlght is sufficient to permit it to travel off the ironing table and to effect automatic lifting of the iron, and to hold. it supported after it passes off the table 15,-a track 82 is formed adjacent one end of the angle bar 73 onto which the roller 70 will ride before the iron leaves the table. 15.

The invention exemplifies an ironing machine in which the flat iron may be reciprocated at will of the operator by mechanism comprising reversible gearing and a motor mounted to travel with the carriage, from which the iron is suspended; which is simple in construction and efficientin operation; which'is readily controllable; and in which the iron may be manually raisedto pass over obstructions 'onthe Work at the will of the o erator.
