To all whom it may cof/wem:

Be it lmown that l, EDGAR l. HILL, a citizen of the United States, residing at @ak Park, county ci' Cook, State yof lllinois, have invented a certain new and useful improvement in ironing Machines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to. make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

i This invention relates to ironing machines and the object oi' the invention is to provide an ironing machine consisting or" a feed roller over which clothes are ined and brought into contact with a heated ironing shoe which is stationarily positioned in the frame of the ironing machine. Another ob-v ject. of the invention is to provide a means :tor moving the roller toward or from the heated-ironing shoe the said means also moving thedriving mechanism into or out of driving engagement. fr further object or" the invention is to provide a drive for an ironing machine which.is very simple and which may he connected or disconnected by movement oi a lever, the said lever heing primarily arranged for moving the roller of the ironing machine toward and 'from the ironing shoe. Another object o'the invention is to provide a worm :tor driving the ironing machine which, when the roller is moved toward the ironing shoe is moved to driving engagement with worm gear, through which the machine is driven and, when the roller is moved away from the ironing shoe, the worin is moved ont oimesh with the worm gear. These objects and the several novel Yfeatures of the invention are hereinafter more iully described and claimed and the preferred form ci construction by which these objects are attained is shown in the accompanying drawings in which l l is an end view of an ironing machine emhodying my invention.

Fig. 2 is a similar view showing the mechanism in the driving position.

Fig. 8 is an enlarged section talren on line 3-8 of Fig. 2.

Fig. i is an enlarged section oi the yieldable connection hy which the feed roller may be moved toward or 'from the ironing shoe.

The ironing machine comprises a frame l having supporting legs 2 and having a iiat table top 3 as shown in dotted lines in Figsl and 2. The Jrameworlr l is provided with a 'oraclret a on which is mounted an electric motor 5 for driving the ironing machine. The motor 5 is provided with a shaft 6 having a ange 'l' on the end thereof provided with a series of pins 8 extending from the face thereof. rlhese pins 8 engage in radial slots provided in the member 9 on the lend oi the shaft l0. The shaft l0 is rotatably mounted in hearings ll on a plate l2 and a worm i3 is secured to the shaft l0 between the hearings ll. rThis plate l2 is provided with a pivot la which is rotatably mounted in the frame l so that when the plate 12 is swung down. on the pivot lll as shown in l" ig. l, the worm i3 is out of mesh with the worm gear l5 and when the plate l2 is swung up as shown in Fig. 2 the rworm 13 meshes with the worm gear l5. ln this position the mechanism is in the driving position and a small gear 16 is provided on the shaft i7 of the gear l5 and this small gear lo meshes with a larger gear 18 which is secured to the outer end of the shaft 19. An arm shown inFigs. l and 2 is rotatably mounted on each end oi the shaft E17-and at the upper ends are provided with hearings for the shaft 19 in which the shaft i9 is rotatably mounted and the shaft 19 is movable through a slot 2l provided in each end of the frame. iThe shaft 19 is provided with hearing 2O on each end thereof as shown in Figs. l 2 in which the shaft is rotatahly mounted the purpose oi which is hereinalter more fully described. Between the ends of the ame is a roller or drain 22 'which is secured to the shaft 19 and which is preferably covered with several layers oi cloth or a cloth '.oad as may he desired. This roller 22 is the `feed roller for the maehine and the clothes to be ironed are placed on the table top 3- and are `ed onto the roller therefrom. in ironing shoe 23 is secured to each end oi' lthe frame and extends from one end to the other and the :tace 2i of the iron shoe is formed on a radius equal to the radius oi' the drum or roller 22, the said shoe heing outwardly 25 so that the clothes will not catch thereon when heing carried around by the roller. rihis ironing shoe is provided with a sheet metal casing 26 which encloses a gas hurne 27 'for heating the shoe, the said gas burner being adapted for connection with a gas feed line as will be readily' understood. The bearing 20 is provided with a boss 28 on one side thereof and a shaft 2 9 is secured therein by a pin` 30 as shown in Fig. 4. This shaft 29 is provided with a slot 31 therethrough and an aperture is provided in the end for the stud 32 which is threaded in to a member 33. This stud 32 is provided with a pin 34 adapted to ride in the slot 31 and prevent the

members

29 and 32 from pulling apart, as willbe readily understood. The member 33 is `provided A with a recess 35 in which the end of the shaft 29 may move and the said member is also threaded on the outside at 36 to receive a nut 37. A coiled spring is interposed between the nut'37 and the shoulder 38 of the boss 28 and by adjusting the nut 37 on the threads 36 the tension of the spring 39 may be increased or decreased as desired. This spring normally holds the

members

29 and 33 apart with the pin 34 engaging the end of the slot 31. The member 33- is provided with a short shaft or stud 40 rotatably mounted in the end thereof which also eX- tends through the end of a lever 41 and the end of an arm A42, the shaft or stud 40 Ibeing held inplace by a cotter pin 43. .The lever 4l is connected by means of a round rod 44,

' shown in dotted lines, to a similari leven 41 at the opposite end of the ironing machine frame and the levers 41 are pivoted on a stationary pivot 45 mounted on the frame 1. The arm 42 at 'the lower. end is pivotally lconnected at 46 to the end of a spring arm 47 which is-attached to a cam 48 shown more particularly in Fig. 3. The cam 48 is pivotallymou'nted on agbolt 49 which is secured in the frame 1 and the member 12 is provided with a recess 50 for the said cam. The member l2 is also provided with a slot 51 as shown in Fig. 3 through which thebolt 49 extends and this bolt acts as a guide for the swinging of the member 12 on the pivot 14.-

When the rod44 and levers 41 are raised from the position shown in Fig. 1 to that shown in Fig. 3 the members 33 and'29 are forced to the right thus moving the bearings 20 and .shaft 19 on'the arms-60 to the right of the slot 21 and moving the roller 22 to engagement with the face 24 of the ironing shoe'. Should a thick piece of clothing be positioned between the roller 22 and the shoe when the lever 41 is raised. the rollerv will toward theironing shoe the driving mechanism drives the roller so that the clothes thereon cannot remain' in stationary contact with the heated iron. The arm V47 is made of spring metal so that should the teeth of the worm engage the outery faces of the teeth of the Worm gear the lever 42 may continue downwardly Without breaking any of the parts and, as the worm gear is rotated it will immediately move into the spaces between the teeth of the worm gear thus allowing the member 12 to` move upwardly to the normal driving position shown in Fig. 2. To stop the driving mechanism it is only necessary to move the rod 44 and levers 41 to the position shown in Fig. 1 which draws the roller 22 mounted on the arms 60 away from the ironworm 13 out of driving engagement withY the worm gear 15. A casing is provided fol;` the mechanism on the outside of the frame ends 1, though not here shown, and acts'as a guard to prevent the clothing from comingan contact with the gears.

' rom the foregoing description it becomes evident that the device is very simple and efcient in operation, will not easily get out of order, is composed of comparatively few parts and is of consequent low manufacturing cost` and provides a device which accomplishes the objects described.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States ise `1.- In an ironing machine, a frame, an ironing shoe extending between' the ends of the frame, means for heating the ironing l yconnecting the end of each lever with the shaft of the feed roll, a driving mechanism for rotating the feed roll comprising a worm lll) .and gear, means for rotating the worm, a
