BUTTON BREAKER ROLL Filed May 25, 1929 INVENTOR, Josefifi Mzqrrqy,

Patented Oct. 8, 1929 were sr're A tame FATE JOSEPH MOM'URBAY, OF HAWTHORNE, NEW JERSEY BUTTON BREAKER ROLL Application filed May 23, 1929. Serial No. 355,546.

This invention relates to so-called button breaker machines in which a fabric is passed zig-zag fashion around a series of rolls having small protuberances or buttons on their surfaces which act to knead the fabric and this work out of the same any stiffness therein, giving it an otherwise-absent pliability and softness. Usually these rolls are made with wooden bodies having the buttons, consisting of small knobs with projecting pins, driven therein, and there is the fault that the buttons work out or their pins break off and the fabric is multilated by the detached buttons or the stubs of their pins duces an intermittent strain on the fabric.

My object is to provide a button breaker roll which is not susceptible to these faults.

In the drawing,

Fig. 1 is a side elevation, partly in longitudinal section, of a button-breaker roll constructed in accordance with this invention;

Fig. 2 is a plan of the strip which I employ to afford the buttons; and

Fig. 3 is a section on line 3-3, Fig. 2.

In carrying out my invention according to the example illustrated I provide a tubular core 1 and around this is tightly wrapped, helically, a strip 2 which is formed at suitable intervals, as by a pressure operation, with the protuberances 3 to form the buttons. The core 1 and the strip 2 are formed of metal, as steel and brass, respectively. The strip is so wound that all the convolutions abut edge to edge, as shown, so as to leave no crevices between them.

To hold the strip in place on the core and provide the roll with bearing supports at its ends and at the same time impart the necessary strength to the completed roll I prefer to supplement these parts as follows: 4 designates cylindrical heads each of which has at one side an axial trunnion 5, affording one of said bearing supports, and at the other side is peripherally rabbeted, as at. 6, the

depth of the rabbet being substantially equal, 5

to the combined thicknesses of the tubular core 1 and the strip 2. The plug 7. of each head resulting from the rabbeting, the diameter of which is equal to the inside diameter of the core, is then fitted into the latter, and having Wound the strip around the core in the manner already stated, the strip is firmly secured at each end by driving a screw 8 through the end of the strip and the end of the core and preferably also into said plug, the parts having been first bored 'and tapped to receive the screw. Finally to cover and confine the screws, add strength to thewhole structure and impart a finish thereto a cap I here consisting of a metal band 9 is fitted over each head with atight fit so as to closely envelep the ends of the strip and core and the screw. If the head or cap (or both) is applied with a close fit, preferably a dr1ving fit, sothat the expanding action ofthe head or the contracting action of the cap (or both) comes somewhat into play the structure formed by the head and cap will add greatly to the strength and integrity of the'entire roll.

The result is a button-breaker roll. whose buttons of course cannot become detached nor break off and which will not be affectedby moisture so as to become bowed andwvhich cannot at any time produce an intermittent action on the fabric and which further is relatively inexpensive to manufacture. It will be noted that the securing means for the portion affording vthe buttons is only at the ends of the roll and is of such character that loosening of securing parts so that they might become detached and cause damage to the fabric being treated is practically impossible.

Having thus fully described my invent-ion, what I claim is:

1. A button-breaker roll including, in com bination, a core and a strip helically wound about and secured to the core and having at intervals integral outward protuberances thereon forming the buttons of the roll.

2. A button-breaker roll including, in combination, a core and a strip helically wound about and secured to the core and having at intervals portions thereof pressed outward and forming the buttons of the'roll.

' 3. A button breaker roll including, in combination, a core and a strip helically wound about and secured only at its ends to the core and having at intervals integral outward protuberances thereon forming the'buttons of the roll.

4:. A button-breaker roll including, in combination, a core, a strip helically wound about the core and having at intervals outward protuberances thereon forming the buttons of the roll, and means to secure the strip to the core including a cap embracing one end of the strip and the corresponding end of the core.

5. A button-breaker roll including, in combination, a core, a strip helically wound about the core and having at intervals outward protuberances thereon forming the buttons of the roll and means to secure the strip to the core including a cap embracing one end of the strip and the corresponding end of the core and forced into embracing relation to the strip with a driven fit.

6. A button-breaker roll, including, in combination, a core having a hollow end, a strip helically Wound about the core and having at intervals outward protuberances thereon forming the buttons of the roll, and means to secure'the strip to the core and affording a bearing support on the latter including a structure fitted into the hollow end of the Corie andalso embracing the strip and said en 7. A button-breaker roll including, in com- I bination, a core having a hollow end, a strip 40 helically wound about the core and having at intervals outward protuberances I thereon forming the buttons of the roll, a head entered into said end of the core with a driven fit and forming a bearing support thereon, and a cap embracing said end and the strip and forced into embracing relation to the strip with a driven fit.

In testimony whereof I affix my signature.

JOSEPH MOMURRAY.
