8 Claims.

This invention relates to an ironing machine for flat work, particularly to a stripper and means for mounting the same in the machine, and has for an object to provide an improved stripper construction which will not mar the work or form marks or lines therein, and it is a further object to provide an improved mounting means for the strippers whereby these strippers may be easily and quickly mounted or demounted, and whereby the position of the strippers may be easily and quickly adjusted or changed for different types of work, thus making as short as possible the time in which the machine must be stopped for changes or adjustment for different operations or different types of work.

With the foregoing and other objects in view I have devised a construction illustrated in the accompanying drawing forming a part of this specification. It is, however, to be understood that I am not confined to the use of the specific construction shown but may employ various changes and modifications within the scope of the invention.

In this drawing:

Fig. l is a longitudinal section through a portion of an ironing machine showing my improved construction applied thereto:

Fig. 2 is a top plan view of the improved supporting means for the strippers;

Fig. 3 is a transverse vertical section through a portion of the machine showing the support for the strippers;

Fig. 4 is a detail section of the securing means at the mounting end of the stripper;

Fig. 5 is a side elevation thereof, the parts being broken away to more clearly show the construction;

Fig. 6 is a side elevation of anend portion of a stripper;

Fig. '7 is a transverse section thereof substantially on line 1-1 of Fig. 6;

Fig. 8 is a front elevation of a supporting block for the stripper; and

Fig. 9 is a side view thereof.

The ironing machine shown comprises a steam chest Ill, which may be made in sections as shown if preferred. The top wall is shaped to form alternate transverse grooves or' depressions I I and ridges I2, the grooves or depressions being curved to correspond with the curvature of the padded ironing rolls I3 and the intermediate portions I2 being reversely curved as shown. Only two rolls are shown in the drawing but it will be understood any desired number may be used as desired. The work I4 being ironed passes between the rolls and the top wall of the steam chest in succession from right to left in the arrangement shown, and between each roll and the steam chest are strippers I5 under which the work passes and which prevent the work following around the roll on the outlet side thereof and guides the work over the intermediate surface I2 of the steam chest. There are a plurality of these strippers for each roll and it is desirable that the strippers for one roll be independent of the other rolls, and it is also desirable that they be independently mounted in order that they may be placed in different relative positions so that the stripper of one roll may be out of alignment with the strippers in the next roll so as to prevent forming marks or grooves in the work. It is also desirable that the strippers be as thin as possible to reduce to a minimum the liability of marking the work.

The strippers I5 shown are composed of thin flat flexible strips or wires, preferably of steel and are supported at the work inlet side of the roll only. At the work outlet side of the roll the free end portion I6 extends over the curved surface I2 of the steam chest to guide the work to the next roll, and to add strength and stiffness to this free end portion so that it will have the desired guiding effect this free end portion is transversely curved as shown in Fig. '7. Improved means is provided for suspending the other end of this strip, which is shown in Figs. 4 and 5. This comprises a grommet I'I secured to the end of the strip, this grommet including a washer I'm having a central opening, the end of the strip I5 being extended through this opening at I8 and wrapped around the washer as shown at I9 and 20. This wrapped portion is then clamped and secured to the washer by an eyelet 2| which comprises two members. One member forms a flange 22 positioned at one side of the washer Na and having a central opening. The other member comprises a flange 23 at the opposite side of the washer and a sleeve portion 24 extending through the washer lid and. the opening in the flange 22, and the free end of this sleeve is folded over onto the flange 22 as shown at 25. This effectively clamps the flanges 22 and 23 to the washer Ila and fastens this strip I5 to the washer.

This device also includes improved means for supporting the strippers I5 in place. The frame of the machine comprises side members 26 at opposite ends of the rolls I3. Supported on these side members are angle brackets 21 secured to the side members by any suitable means such as screws 28, and they include downwardly projecting portions 29 at the inner sides of the frame. Mounted at the inner sides of these downwardly projecting portions are longitudinal extending bars 36. These bars may be of difierent shapes but preferably are angle bars having their upright flanges against the inner sides of the portions 29 of the brackets and to which they are clamped by clamps 3| engaging the opposite sides of the flange and clamped against the flange and the bracket portions 29 by screws 32 threaded into the portions 29. The opposite end of the clamp 3| has a rib 33 to engage the surface of the bracket portions 29 and form a pivot on which the clamp 3| will turn to clamp the bar 30 to the bracket portion 29. This mounting means effectively clamps the bars 30 to the brackets and will also permit horizontal adjustment.

Extending transversely between the longitudinal bars 33 are transverse cross bars 34. These may be of different shapes but are also preferably angle bars each arranged to provide an upright flange 35, The horizontal flange 33 rests on supporting plates 31 resting on and supported by the horizontal flange 38 of the longitudinal bars 33 and secured thereto by any suitable means, such as the bolts 39. These plates 3'! and the portions extending under the transverse bars 34 have longitudinal slots 40 through which clamping bolts 4| may extend and be threaded into the lower flange 36 of the cross bar. This permits relative adjustment between the cross bars 34 and the longitudinal bars 30.

The flexible strippers I are suspended from the cross bars 34, and an improved and simplified means for suspending them from the cross bar is shown in Figs. 8 and 9. This comprises a substantially inverted U-shaped block 42 which is adapted to seat over and embrace the upper edge of the upright flange 35 of the cross bar 34. It is a simple matter to mount this block on the flange as all that is necessary is to seat it over .the upper edge thereof, and it may be adjusted to any position desired on the cross bar by merely sliding it along the edge of this flange. It may then be clamped in adjusted position by tightening the set screw 43. This eliminates drilling and tapping holes in the cross bar and also permits easy and quick adjustment which was not possible with the old form. Projecting laterally from the outer side of the block 42 is a stud 44 over which the grommet 2| secured to the end of the flexible strip l5 may be slid to suspend the strip from this block. The free end of the stud 44 is curved upwardly as shown to retain the grommet on the stud. It will be evident that with this construction the flexible stripper is effectively and securely suspended from the block .42 and that it may be quickly and easily applied to or removed therefrom by the simple operation of either sliding the grommet on to the stud 44 or lifting it therefrom.

The position of the strippers with respect to the rolls and to each other may be easily and quickly adjusted or changed for different work by merely sliding the blocks 42 along the flange 35, and, as will be seen from Fig. 2, as the strippers for one roll are independent of and disconnected from the strippers of the next roll, the strippers for one roll may be arranged in staggered relation and therefore out of alignment with the next or other rolls, and thus prevent successive strippers engaging the work at the same point. It is very desirable in this class of devices that there be easy adjustment of the strippers without detaching. Also that there be allowed quick 10-- eating, adding or removing of stripper wires as required to accommodate various kinds of work. This has to be done quickly and easily in order to reduce to a minimum and make as short as possible the time required for repairs, adjustment and changes for different work or different operations on the machine. These advantages are effectively secured with this construction. It will also be seen that by this means of mounting the flexible strippers l5, comprising the block 42 and the stud 44 cooperating with the grommet H, the

pull of the strip |5 on the grommet I1 and the block is in the plane of the grommet so that there is no bending of the strip with consequent liability of breaking it. The grommet also makes it a very easy and simple matter to remove the strippers for any reason,
