tubular body I i.

It is to be underto which this invention is oi' the type wherein the roll is supd driven solely fr om one end of the Extending longitudinally and axially of the roll III is a tubular sleeve I8, for supporting said roll body II, and which may be understood to be mounted within the roll III in a manner somewhat similar to that embodied in single or multi-speed commercial forms of rotating roll type ironers. 'Ihe end of said tubular sleeve I6 is supported concentrically within the tubular body II, as will hereinafter be described. Disposed within the tubular sleeve I6 is a driving shaft I1 which is connected to suitable means for imparting rotation to the roll III. It is to be understood that the opposite end of said shaft, (not shown) is connected to conventional driving mechanism which is capable of manipulation under the control of the operator.

As may be seen in the drawings, the shaft I1 extends a short distance beyond the tubular sleeve I6, and rigidly secured to said extended portion of the shaft by means of one or more set screws I3, is a drive element 20 whose exterior surface is provided with a plurality of splines 2l. Journaled and axially movable on the outer end of the sleeve I6 is a housing 23 which is provided with a hub portion 24, having a bushing 25 driveiltted therein for bearing support upon the exterior of the sleeve I6. Said hub portion continues into an outward extension 26 the extreme end of which is threaded and engaged by a closure element 21 which serves as a convenient knob for operating the multi-speed mechanism. The internal portion of said extension 26 is provided with splines 29 cooperating with splines 2I of the element 20. Positioned intermediate the adjacent ends of the splined element 20 and the tubular sleeve IG and circumscribing the driving shaft I1 is a washer 3| which serves as a stop for one shoulder of the internal splined portion 23, oi' the hub extension 26, and limits inward movement of the housing 23, as seen in Fig. 1. The opposite shoulder of said splined portion 29 limits the outward movement of the housing 23 by contact with a cap plate 33 secured to the end of the splined element 20 by screws 34, as.

seen in Fig. 2.

The inner end of the housing 23 terminates in an enlarged annular drum-like portion 23* in the end of which is press-fitted an annular clutch element 36 in the form of an internal gear ring. adapted for selective engagement with a cooperating clutch element 31 secured by means of bolts 33 to a dished support 39 which is formed with an annular flange 33", spot-welded or otherwise rigidly secured to the interior of the tubular body Il. 'The central portion of said member 33 is formed flange 33h in which is press-litted a bushing 40 adapted for journal support on the external surface of the tubular sleeve I6. The clutch element 31 may be of any desired form and,` as herein shown, is in the form of a gear, adapted to mesh with the gear ring 38.

In the position of the parts shown in Fig. 1 the shaft I1 drives the splined element 2li, which in' turn rotates the housing 23 through the splined connection of the hub extension 28, and because the clutch elements 38 and 31 are in operative engagement. motion is transmitted directly through the clutch element 31 to the support 39, directly rotating the roll III. It is to be understood that this arrangement of the driving mechanism rotates the roll Iii at which is considered a normal operating speed.

For changing the speed of rotation o1' the roll ID to low or slow speed, the knob member 21 with an annular reversely extending is grasped and pulled outward to the position seen in Fig. 2, in which position the housing 23 has been moved so that the gear ring 36 is in mesh with a pinion 45 journaled on a stud 46 rigidly secured in a boss 31'L of the clutch member 31. Said pinion 45, as may be seen in the drawings, is constantly in mesh with a planet gear 48 which is rigidly secured on the supporting tube I8 by one or more set screws 43, in its hub 43. In this position of adjustment of the mechanism it will now be apparent that the pinion 45 which is connected to the clutch member 31 and which in turn drives the roll by virtue of its connection to the dished support 33, substantially reduces the speed of rotation of the roll III.

It is to be understood that the end of the teeth of the pinion 45 adjacent the boss 31 and both ends of the teeth of the gear ring 3B, as well as the outer ends of the teeth of the gear ring 31. are beveled so that upon longitudinal movement of the housing 23, the gear ring 36 may quickly and easily mesh with either the teeth of the clutch member 31 or the teeth of the pinion 45. By virtue o'f this construction it is possible to change the speed of the roll while it is operating.

As above mentioned, the washer 3I serves as a stop adapted to be engaged by the shoulder oi the splined portion 29 of the hub extension 26'when said housing is moved inwardly to the position seen in Fig. 1, while the shoulder formed at the opposite end of the splined portion 29 is adapted to abut against the cap plate 33 when the housing 23 is withdrawn to the position seen in Fig. 2 which corresponds to the low driving speed for the roll I0.

Although I have shown and described a preferred embodiment of my invention, manifestly it is capable of modification and variation without departing from the spirit and scope thereof. I do not, therefore, wish to be understood as limiting this invention to the precise construction herein disclosed, except as it may be so limited in the appended claims.
