IRONING ROLL Filed June 13, 1928 INVENTOR lub ATTORNEY Patented Mar. 25, 1930 iran stares GEORGE A. MUMFOB-D, OF ROCEESTER, NEW YORK IRONING ROLL Application. filed .Tune 1 3,

The present invention relates to cushions such as used in padded rolls and beds of ironing and pressing machines and other places where similar conditions exist. An object of this invention is to provide a construction in which the cushion has greater durability and will not mat. Another object of the invention is to provide a cushion which is so constructed as to provide a large space for the collection of vapor. Another object of the invention is to provide a cushioned surface Vformed of a plurality of rigid surface forming elements so mounted that no lateral strains are imposed upon the resilient means H which supports them. A still further object of the invention is to provide a cushioned surface formed of a plurality of surface forming` elements which are readily removable to permit the repair of the cushion.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Fig. l is a transverse section through a padded roll of an ironing machine embodying the present invention;

Fig. 2 is a sectional view through a frag- 39 mentary portion of the roll on the line 2 2,

F ig. 3 is an enlarged sectional view through one of the guides and one of the surface forming elements; and

Fig. A is a view showing one of the elements partially in section and partially in side view arranged in one of the channels or guides, the resilient means also being shown in partial section and partial elevation.

In the illustrated embodiment of the invention, 1 illustrates a shaft having collars 2 thereon supporting a hollow cylinder 3 forming the support as a whole for'the cushion. The cushion, in this instance, is formed by a plurality of surface-forming members 4 in the form of rigid plates provided with perferations 5 through which the vapor or steam may pass after passing through the covering pa d 6. so as to keep the pad in a dry condition.

The members 4, in this instance, are ar- 1928. Serial No. 285,151.

ranged in parallel lines and guided against lateral movement on the supporting cylinder 3. To this end, the supporting cylinder is provided with a plurality of longitudinally extending guides. Each of these guides are of channel formation having a bottom wall i conforming to the cylinder 3 and secured by welding to the latter. From this bottom wall project two side walls 8 which have at their outer edges inwardly turned Hanges 9 60 forming a restricted outlet for the channel and also acting as stops. Each channel has al plurality ofsurface forming members t guide ed therein, and arranged end to end. To this end. a web ll is projected from the rear face of each elongated surface forming member 42 ane is guided by the walls of the restrictedy ortlet 10 of the channel. At the free end of ths web two outwardly extending flanges l2 are provided which cooperate with the side walls 8 and the flanges 9. This cooperationl between the iianges l2 and the side walls andi, also between the web l1 and the ends of the. iianges 9 prevents any sidewise movement of the surface forming member et while permitting the latter to be depressed. The flanges 9 limit the outward movement of the surface fer-ming members.

Resilient means is interposed between the surface forming members and the support for said members. In this instance, this resilient means comprises a plurality of leaf springs 13 superimposed one upon the other and loclred together by clips 14 having side arms 14a fitting in notches 20 in the sides of 85 the springs. These leaf springs form an arched spring means and the top of each arch abuts the bottom 7 of the channel or guide while the ends of the arch abut the flanges l2. To confine each set of springs to one surface forming member each of said surface forming members have projecting from it two stop lugs l5 adjacent opposite ends of each member and serving to conline a set of springs between them.

Removable heads 16 close the ends of the drum or cylinder 3 and extend beyond said cylinder substantially to the periphery of the roll as a whole. One of these heads is provided with ports 17 opening laterally be- 100 1G apparatus connected to the roll, little or no moisture collects upon the springs and, in this way, the life of the springs is extended.r

It is apparent that a button or other hard device passing between the padded roll and an ironing surface will cause one of the sur# face forming members to be pressed inwardly against a set of springs 13. Of course, the surfacev forming member will roel; in the channeled guide, depending on' which side of gmthe center of the member is engaged by the harddevice, and will return to its initial position after passing out of engagement with such device. Each surface forming member is removable or is held against lateral shiftgsging so that no stra-inis imposed upon the springs or resilient devices which hold the surface forming members in normal positions. The devices may be readily removed from the channels by removing them longi- :Le-tudinally of the channels, causing the springs to travel withthem. A ylarge space is pirovided in which the vapor may collect andthe springs are so mounted that only a small amount of the jvapor can reach them.

- It will be noted that longitudinally extending channels are provided from one endV oftheroll to the other and the vapor passing into and through these channels tends to maintain thecush'ioned surface in a heated -iaconditionand thus in a dry condition. Art

the same time the resilient or spring means which opposes the movement of the surface forming members is housed against the action of the vapor.`

s What I claim as my invention and desire to secure by Letters Patent is:

l. An ironing surface comprising a rotary support, a pluralityof surface forming meinbers, resilient means acting upon said sur-A face forming members to hold them in normal positions, and guiding means between the ro' tary support and the surface forming kmembers preventing sidewise movement of the Y surface forming members in the direction of turning'of the rotary member.

2. An ironing surface comprising a rotary support, o-f'a plurality of surface forming members each having a rigid web projected vfrom the inner side thereof and extending C? longitudinally of the axis of rotation .of the support, resilient means acting on said surface forming membersto hold them in nor'- inal positions and means cooperating with opposite sides of said webs to guide the surface forming members on the support toward parallel relation to each other and tothe axes of rotation of the support, a plurality of surface forming members guided in each of said channels and held against sidewise movement in the direction of turning of the rotary support, and resilient means arranged in the channels for holding the surface forming members in a normal position.

Yt. An ironing surface comprising a support, a plurality 'of surface 'forming members providedwithopenings and movably mounted on the support, resilient means opposing the' movement ofthe lmembers on the support, and means housing the resilient iieaiis and providing spaces through which vapor may be drawn from the openings in the surface fo-rming members without contacting with the resilient means.

5. An ironing surface. comprising a plur f rality of surface forming Vmembers formed with perforations and karranged in Vparallel rows, resilient means opposing the movement of said members, and means enclosing said resilient means and providing parallel channels through which vapor passing through the surface forming members may be drawn without contacting with the resilient means. k6. The combination with a channel member having a restricted outlet, of a surface forming member having a web projected from the inner side thereof and guided by the walls of the restricted outlet of the channel, means carried by said web for limiting the outward movement of the surface forming member, two abut-ments carried by the web within the channel, and bowed spring means having its end portions cooperating with the abutments and its bowed Vportion cooperating with the bottom of the channel member. l

7. An ironing surface comprising a rotary support, a plurality of parallelfchannel members arranged longitudinally of said support to provide vapor spaces between them, a plurality of surface forming members guided in each channel, and resilient means opposing the movement of the surface formingk members and arranged in said channels.
