HILL IRONER SHOE SUPPORT Filed Oct. 18, 1929 INVL'NTOR Mr/vsss A ITORIYVEVJ Patented Feb. 17, 1931 UNITED STATES PATEiNT' OFFICE HERMANN HILL, OF SYRACUSE, NEW YORK, ASSIGNOR TO SYRACUSE WASHING MA- CHINE COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF DELAWARE IRONERLSHOE SUPPORT Application filed October 18, 1929. Serial No. 400,709.

This invention relates to anew and improved 1roner shoe support.

In the types of ironlng machines where lating the shoe which will cause the shoe to be moved toward the roll and held there temporarily under a predetermined pressure and then be moved outwardly away from the roll to facilitate the introduction of, clothes between the shoe and the roll.

In order that the ironing operation may be properly done, it is necessary that the shoe be held against the roll under a considerable pressure for if this is not done, the result of the ironing operation will not be satisfactory.

In order to insure that the shoe will be held against the roll under the desired pressure with the minimum amount of movement of the parts and the minimum expenditure of energy by the actnating mechanism, it is usual to provide on the support which carriesthe shoe, a spring under pressure which spring will assist in forcing the shoe against the roll when the same is brought into contact with the roll by the manipulation of the shoe support.

In order that the spring and the rest of the mechanism ma function with the greatest efiiciency, it is necessary'that the spring remain under its highest tension up to a point just before the shoe comes into actual physical contact with the roll.

In devices hitherto known to the art, the tension of the spring may be adjusted, but no provision has everbeen made whereby in addition to the adjustment of the tension of the spring, the shoe support may also be adjusted with reference to the actuating mechanism on which it is carried so that its relative position in relation to the roll may be varied irrespective of any movement of the actuating mechanism.

I have found such a supplementary adjustment of the shoe in relation to the actuatmg mechanism on which it is carried to be to extremely advantageous not only during the initial assembly of the ironer but also because it provides a means for compensating for any change in diameter of the roll itself.

The rolls used in these devices are, as a matter of necessity in order to obtain the best results, covered with a built up resilient covering, usually of cloth. This being the case, the covering from its very nature will in use tend to flatten down so that the diameter of the roll will become smaller. If, under such conditions, no adjustment is possible of the shoe in relation to the actuating mechanism, the actuating mechanism will be called upon to move the shoe support and the shoe through a greater are before pressure will be exerted by the shoe on the roll and the mechanism will lose materially in efficiency.

The main object of my invention is to provide a support for the shoe of an ironing machine which will be provided not only with a means for tensioning the spring which is usually used with devices of this character but which will also provide a means permitting the relative adjustment of the shoe to the actuating mechanism on which it is carried which adjustment will permit a change inliihe position of the shoe in relation to the r0 Other objects and advantages relate to the size, shape and relation of parts all as will more fully appear from the following description taken in connection with the accompanying drawings in which Figure 1 is a section on line 11 of Figure 2.

Figure 2 is a side elevation, partially broken away, of my shoe support and the shoe carried thereby.

My device, being adapted to be used with any types of ironing machines having rotating rolls, I have not here shown any particular type of ironing machine'or any particular type of actuating mechanism for the shoe, it being understood, as will be obvious to anyone skilled in the art, that the shoe support carrying the shoe will be moved intermittently towards and from the roll so that pressure may be intermittently exerted by the shoe against the roll.

' In Figure 2,1 show aroll 17 and an actuating shaft 2. On shaft 2 is carried a shoe support 3 on the forward end of which is carried the shoe 15.

Referring to Figure 1, the shaft 2 has secured thereto, as by a key 5 and a set screw 6, a yoke 7. Yoke 7 has at the rearthereof an aperture 8 having on its rear face an internal shoulder 9.

On the upper end of yoke 7 and between the opposite sides thereof is pivotally mounted a rock arm 10 as by a pivot pin 11. The lower end of rock arm 10 is curved inwardly and downwardly and carries a set screw 12 adlalptzed to contact with the inner face of yo e On the upper end of rock arm 10 is pivotally mounted a forwardly extending link 13 as by a pivot pin 14. On the forward end of link 13 is secured, in any convenient way, (a new and improved way is disclosed in my co-pending application filed August 29, 1928, on Shoe mounting for ironing machine, Serial No. 302,767, which has matured into Patent No. 1,741,298 dated December 31, 1929) a shoe 15 preferably provided with an internally located heating element 16.

The front face of shoe 15 is curved to conform with the curvature of the roll 17 with which it is adapted to contact. Just beneath pivot pin 14 and in rock arm 10, I provide a set screw 18 adapted to contact with the rear face of shoe 15 to prevent the same from moving downwardly about the pivot 14 when the shoe 15 is out of contact withthe roll 17.

A leaf spring 19, here shown as composed of four leaves of different lengths, has its bottom end seated in the bottom of aperture 8 and has its upper end in contact with the rear end of link 13.

In the bottom of yoke 7 is positioned a set screw 20 which is adapted to be screwed inwardly against the lower end of spring 19 to cause the same to be forced against the shoulder 9.

Shoulder 9 functions as a fulcrum for spring 19 so that the pressure of the upper end of spring 19 against the rear end of link 13 may be increased by increasing the pressure of set screw 20 against the lower end of spring 19.

In order to vary the angular relation of rock arm 10 to yoke 7, which in turn will vary the position of shoe 15 in relation to roll 17, the actuating parts being at rest, set screw 12 is provided.

Rock arm 10 being pivotally mounted on the upper end of yoke 7, it will be obvious that if set screw 12 is screwed inwardly through the lower-end of rock arm 10 with its forward end abutting the inner face of yoke 7 such lower end of rock arm 10 will be moved inwardly away from yoke 7 which will cause the upper end of rock arm 10 to be moved outwardly; This outward movement of the upper end of rock arm 10 carrying link 13 will cause shoe 15 to be moved outwardly and away from roll 17 Conversely, if set screw 12 is screwed outwardly in the lower end of rock arm 10 such lower end will be permitted to move towards yoke 7, carrying the upper end of rock arm 10 inwardly to move shoe 15 towards roll 17 When shoe 15 is out of contact with roll 17 the lower end of rock arm 10 carrying set screw 12 will be moved and held firmly in contact with yoke 7 due to the fact that spring 19 will tend to move the upper end of rock arm 10 about the pivot 11 and this movement will cause the lower end of rock arm 10 to be moved outwardly towards and into contact with yoke 7.

When the ironer is initially assembled, the shaft 2 is manually placed in a position wherein further movement of the actuating mechanism will move shoe 15 into contact with roll 17.

With the parts in this position, the set screw 12 is manipulated so that the shoe 15 is carried inwardly to a point where it is just out of contact with roll 17. Set screw 20 is then manipulated to place spring 19 under the desired tension so that when the mechanism is actuated and the shoe brought into contact with the roll 17 the spring 19 will cause the proper amount of pressure to be exerted by shoe 15 against roll 17.

The amount of pressure exerted by shoe 15 against roll 17 is determined by the tension of spring 19 because of the fact that after shaft 2 is rotated to carry the shoe 15 into contact with the roll 17, a slight additional movement of rotation of shaft 2, shoe 15 being in contact with roll 17, will cause rock arm 10 to be moved about its pivot 11, carrying set screw 12 out of contact with yoke 7, so that the shoe 15 will be held under pressure contact with the roll 17 solely by the spring-19. This position of parts is shown in Figure 1.

If, after use, theroll 17 becomes less in diameter so that it will be necessary to move the shoe 15 through a greater are in order to bring it into' contact with roll 17 and thus impair the efliciency of the mechanism, set screw 12 may be again manipulated to position shoe 15 in the correct relation to roll 17 as heretofore described and the tension on spring 19 may be increased by means of set screw 20 so that the proper pressure of shoe 15 against roll 17 will be assured.

I have here shown a particular form and arrangement of parts but it will be understood that such form and such arrangement may be varied to a considerable degree without departing from the spirit of my invention, for although I have shown and described a specific structure and form of part as an exemplification of an embodiment of my invention, I do not desire to restrict myself to the exact size, shape or relation of part, as

various changes may be made within the screw in contact with the yoke.
