Application filed June 4,

This invention relates to ironing machines of the mangle type.

One of the principal objects to provide, in connection with an ironing rolliu a ma- 5 chine of the type mentioned, a plurality oi' padded rolls for feeding the work in contart with the ironing roll, there being a provision for driving one of the feed rolls at a slower peripheral speed than the others to to create a drawing etl'ect on the material being ironedand produw a glossy linish.

Another important object. is to provide a machineof the type mentioned having an electrically heated and d1'iven,,ironing roll of an open end type, that is, supported and driven at only one end, thus afi'ording a wider rangeof possible uses for the machine and making the entire area of the ironing surface available for use. p v

Still another import-mt object of the in- .vention is the provision of a guard which positively eliminates the danger of getting lingers caught bet-Ween the rolls, the guard being arranged to control. the electric car cuit ot' the driving motor furnishing the power to turn the ironing roll so that the machine thrown out ofoperation the in stant there would otherwise be danger of the operators fingers coming between the rolls, while the guard also afi'olrds'a convenient means for starting and stopping the anachine at the will of the operator without the necessity of using the starting switch. In additioi'rto this safety t'eature..-the in-' vention provides a means hereinafter described for instantly releasing the feed rolls from operative relation to the ironing roll by the operation of a treadlc within con-- venient reach at any point along the, front of the machine. V

The invention is described in more complete detail in the following specification, Where-in reference is made to the accompanying drawings illustrating'one embodiment in Which .Figure 1 is a. front view of the machine; Fig. 2 is an end view taken from the right hand end of Fig. l: 7

Fig. 3 is aview taken from the oppositeend of the machine; Fig 1 is a top view of Fig. l; and 5 is a longitudinal section through the ironing roll and the mounting thereof. Thesame'referencenumerals are applied to corresponding parts throughout the \'ic\\' s.

11'. The current'for the heating units is sup- 7 plied in the rotation of the roll in a manwas. snai Ho. nasss.

The machine illustrated has a frame composed of end uprights (Mind 7 on a base 8 suitably braced by cross-members 9. An ironing roll 10 of the open end type is supported at only one end on the a right 6 in ny manner illustrated in Fig. 5. his type of roll oflers manyadvantages 'over the closed end type and makes it possible to iron pieces which" would otherwise be too wide for the machine. While the construction'and the mounting of'the roll may be varied to a considerable extent, 1 have chosen to select for the purposes of illustration a mounting, as shown in ,Fig. 5,'eomprising a jonrnal ll received in a beating 12 provided in the. upright 6. The journal 6 constitutes a hub onto which the parts of the roll 10 are assembled. Thus an inner shell 13 ofone or two pieces has a tapered bore to fit on the tapered end 14 of the journal 11 and thereby become centered with respect to the outer shell 15. The outer shell is supported on a ledge 16 provided on an end plate '17 which .in turn is mounted on a ledge 18 on the journal 11. A cap 19 for the other end of 80 theu-oll 10 is received in? the countersunk end '20 of the outer shell and has a tapered boss .2l'to-be receivedwithin the end of the inner shell 13-, thus centering the shells 13 and I5 with respect to one another. A standard is provided in the form. of a rod 22 threading at one end in the journal 11 and receiving a nut at its other end to hold the parts in assembled condition. Anannular coil chamber 2* is provided between the shells l3 and 15 for the heating units 25, there being suit-I able insulation therefor. shown at 26. Lead-ins 27 for the heating units extend to terminals 28 on the outside of the journal ner similar to that'shownin my Patent No; 1,481,225, dated January 15,1924. Briefly stated, I provide two conducting rings 29 and 30 each of which is associated with a 100.

separate trolley wheel 31associated with one of the tern'iinals' 28. The conducting rings 29 and 30' are in turn associated with the wires 32 and 33 respectively leading to the smirce of electric current. The roll 10 is arranged to be drivenbv the turning of the journal 11 with a worm gear 334 preferably formed integralwith the journal. The gear 54 meshes with a worm 35 on the armature shaft-of a motor 36 supported on abracket 37 mounted on the back of the upright 6, as shown in Fig. 3. The end plate 17 and the worm gear 34 together afford thrust bearingsof ample radius with respect to the journal 11 on opposite sides of the upright 6. it will be obvious that any suitable antifriction bearing elements may be interposed in the journal bearing and in the thrust bearings if so desired. The lubrication of these bearings is herein illustrated as accomplished through the oil ducts 35. j

The ironing roll 10 has spur gear teeth 39 formed on-the periphery of the outer shell 15 thereof adjacent the end plate 17, as shown in Fig. A plurality of padded rolls 40, preferably three, are disposed about the ironing. roll, as shown in Fig; 2, the first roll, designated A, being at the top of the roll 10 and the other two, designated B and C, respectively being advanced approximately 45 and 90 with respect thereto around the back of the roll. Rolls B and C are provided with gears 41 on the end thereof meshin with the gear teeth 39 so that these two rolls are driven at approximately the same peripheral speed as the ironing roll 10. A supporting frame 42 is provided for the three rolls and, as will presently appear, is arranged for movement to carry the rolls simultaneously into or out of operative relation to the ironing roll. The roll designated B is provided with a spur gear 4.3 on the .end thereof opposite the gear 41.

The roll designated A carries a gear 44 which, it Wlll be seen on comparison in Fig.

2, is appioxin'iately one and one-half times as large as the gear 43, the purpose being to .provide a ratio of about two to three between the gears 43 and 44 so that when the roll A is driven from the roll B by the meshing of the intermediate idler gear 45 with the gear 44, the roll A will be turned at a somewhat slower peripheral speed and thus create a drawing effect on the material being ironed. The rolls B and C will thus be caused to slide relative to the work as they are turning at a faster peripheral speed than the lineal speed of the material. This, as is well known, will produce a glossy finish, which is desired on certain kinds of, work. The gear 45 is in constant mesh with the gear 43 and is arranged to be thrown into mesh with the gear 44 at the will of the operator as in the case of a shiftable back gear on a lathe or the like. The gear 45 is, therefore, mounted on a shiftable hand lever 46 within convenient reach of the operator standing at the front of the machine. The lever 46 is preferably provided with a spring pressed detent at 47 to engage in either one of two openings 48 provided on the side of the frame 42 to hold the gear 45 in or out of mesh with the gear 44. It will be obvious that with the gear 45 out of mesh with the gear 44 the rol designated A will operate smoothing out the work.

on a bracket 50 supported on the upright 6. The work leaves the machine over a shelf 51 supported by brackets 52 on the uprights 6 and 7. The shelf 51 extends beneath the ironing roll and has the inner end portion thereof curved upwardly around the back of the roll, as shown at 53, to provide a chute for guiding the work as it leaves the roll designated G forwardly over the shelf 51.

There is, therefore, no opportunity for the work to become fouled with any part of the machine. The table 49, as shown in Fig. 2, terminates in front of the point where the work enters between the ironing roll and the first padded roll designated 1%... A guard. or shield 54 is pivotally mounted on the frame 42 at 55 and disposed across the entire front of the roll A so that the work has to pass beneath it into the machine. A lug 56 projects from the top of the guard 54 and carries a contact terminal 57 connected in series with the starting switch for the motor 36.

A lug 58 projecting from the frame 42 bears another contact terminal 59 normally ongaging with the contact 57 to complete the circuit through the motor 36. The circuit is broken by pressure against the guard 54 against the action of coiled compression springs 60 disposed about a rod 61 and acting between the rod and the lugs 56 and 58 to keep the contacts 57 and 59 normally closed. The guard, therefore, yields only under appreciable pressure such as might be occasioned by the operator unconsciously moving his hands in too close to the rolls in The moment the guard is moved in the manner stated the machine is stopped. The guard, therefore,

provides for the safety of the operator and 1 it is impossible to get his fingers near the danger zonewithout bringing the machine to a standstill. The guard may also be used as a convenient means for starting and stopping the machine without touching the starting switch.

Another safety feature is provided by enabling the operator to instantly release the padded rolls from operative relation to the ironing roll in the event anything becomes caught between the rolls. A. treadle (32 pivoted at 63 extends across the front of the machine to be within easy reach to the operator at any time. A link 64 joined to the lreadle 62 is connected with the intermediate pivot (55 of a pair of toggle links 66 and 67. The former is pivoted to a stationary part of the machine at 68. The link 67 has a pin andslot connection at 69 with a yoke 70 pivoted at 71 to a rocking lever 72. The

fit!

' vparts in the relative position 3 own in latter is arranged to oscillate ash aft 731'sceived in bearings provided on' brackets 74 mountedon the uprights 6 and 7. A pair of arms 75 support the frame-42 and are arranged torock with the lever 72 in the oscillation of the shaft. The. link 67 is slidable within the yoke 70, as indicated in dotted lines in Fig. 2 to the extent permitted by the lost motion connection 69. "A compression spring 76 acting betweenv the yoke 70 anda shoulder on the link 67 yieldin ly holds the 2. In the event any impediment is fed between the rolls as, for example,buckles or buttons and the like, the padded rolls are free to yield to the extent afi'ordedby the lostmotion connection 69. The spring 76,

however, normally kee s the padded rolls inproper. contact with t e ironing roll. The padded rolls'40 with their supporting frame 42 overbalance a counter-balancing spring, or springs 77 under th'e'action of gravity to ,such an extent as to be held with alight pressure against, the ironing roll. Due to the counter-balancing springs 77, only a. very lightfoot pressure is required on the treadle 62 to elevate the padded rolls out'of operative position. -Furthermore, the counterbalancing springs hold the, padded rolls in substantially floatin relation to the ironing roll so that they w 1 yield readily and pre vent the breakage of buttons and avoid any possible. jamming of the machine.

It is believed that the foregoing description affords a clear understanding of the invention as expressed in the objects prefaced above and while I have illustrated but a single embodiment, it should be understood that various changes might be made in details without sacrificing the more important advantages derived by the present construction. Such modifications are to be considered asembraced within the spirit and Scope of the invention as expressed in the appended claims.
