Cissell Manufacturing-(10., Incorporated, Louisville, Ky.,,a corporation of Kentucky Application December 18, 1952, Serial No. 326,669
4 Claims. (Cl. 259-1) cation from a unitary supply therein for all moving elements thereof; (2) readily mounting thereto, and demounting therefrom a fabric processing drum of the overhanging type so that it can be installed or removed expeditiously therefrom by one person without disturbing the oil supply within the housing; (3) forestalling the egress or ingress of the fluids of each unit, in eifect, preventing the liquid oil of the gear set from creeping or leaking into the drum thereby damaging fabrics in process within the drum or the passage of the washer liquids therein from entering the gear housing or seeping onto the gear housing or onto the frame of the apparatus.
In this application I show and describe only the preferred embodiment of the invention simply by way of illustration of the practice thereof, as by law required. However, I recognize that the invention is capable of other embodiments and that the several details thereof may be modified in various ways all without departing from the invention. Accordingly, the drawings and description herein are to be considered as merely illustratrative and not as exclusive.
In the drawings:
Figure 1 is a plan view of the driving mechanism with a portion of the housing broken away to show the rotating members therein. Also shown are a portion of the dryer casing and a fragment of the dryer drum spider.
Figure 2 is a vertical view of Fig. 1 also With a portion of the housing removed to show the members disposed therein.
Figure 3 is a section of Fig. 2 along line 3, 3 primarily to disclose structure by which the high speed bearings are supplied continuously with the lubricant.
Figure 4 is an elevation along line 4, 4 of Fig. 2 to show a fragment of the spider on which the rotating drum is mounted.
Figure 5 is a vertical central section along 5, 5 of Fig. 1.
Figure 6 is a section along line 6, 6 of Fig. 5 to reveal the interior contour of the top portion of the housing that collects and distributes oil to the high speed roller bearings.
Since one of the objectives of the incident invention is the provision for mounting and demounting of the drum by only one operator, a free fit must be provided between shaft 27 and the bore of hollow shaft 15A. Eachend of this shaft is threaded to receive cap screws 28 and .29. that engage respectively washers 28A, 29A, the: former contacts the vertical face of shaft 15A While the :latter engages the outer vertical face of drum spider 30. When the capscrews are:tightened, or made fast, the inner face of the spider binds oil sling disk 31 to the adjacent vertical face of shaft 15A. The latter is recessed to receive flange 31A of the disk. Thus, it will be perceived that when assembled for operation, gear shaft 15A, straight tubular shaft 27, disk 31 and the drum are in effect an integral whole and obviously rotate as a unit on roller bearings 16, 16.
Best seen in Fig. 5, vertical channel 12, a part of the case for the drum, has aperture 32 through which the hub of the spider projects. Attached to this channel is a trough 33, provided to catch any oil from the housing that may seep past the adjacent seal in case of failure. Between the channel and the spider is a block of highly absorbent material 34, provided to arrest seepage in the event of porous materials or loosened cap screws.
With the oil level in housing 10 determined by fitting 26A, roller bearings 16 and gear 15 are continuously bathed in oil. The gear carries oil to the worm which, under normal high speed rotation, throws it against the inner face of the arched recess 13. Prior to the inclusion of ribs 13A the oil formed in drops and fell back into the chamber of housing 10 without reaching the roller thrust bearings 18. These ribs are fashioned with a gradation downwardly from the center area of the arched recess to the extremities thereof, which terminate above the rotating cone of the roller thrust bearings, thereby delivering oil thereto, thusly, providing continuously a supply of oil to these vital members.

uncovered, and external of the tubular shaft for longitudinally clamping the opposing ends of the tubular shaft between the drum spider and the removable clamping means, thereby to permit uncoupling of the drum from the driven tubular shaft easily and rapidly by removing the readily accessible clamping means at the uncovered end of the second shaft.
3. Driving mechanism for the rotatable drum of a drying tumbler or the like comprising, a stationary housing mounted exteriorly of the drum; spaced bearings on said housing; a hollow tubular shaft mounted in said bearings; a driving element fixed to said tubular shaft between said bearings; a drum spider having an apertured hub with opposed clamping faces; a second shaft of substantially uniform diameter, having one end freely and releasably received in the bore of the said tubular shaft,
and the other end in the aperture of said hub; a clamping washer on the outer face of the hub, and a clamping washer on the outer end face of the tubular shaft; and threaded clamping means 'on each end of said second shaft for clamping each respective washer to the face of its adjacent member and bringing the adjacent faces of the tubular shaft and hub into engagement, thereby to secure the shafts and hubs together.
