DRIVING MECHANISM FOR CARDING-MAGI-IINE STRIPPER ROLLS.

Application filed March 10, 1926. Serial No. 93,737.

It has been proposed heretofore to apply a continuously operating stripper roll to the cylinder of a carding machine, and such a construction is shown in British Patent No. 216,480. The present invention relates to driving'mechanisms for such rolls and it aims to facilitate the installation of such rolls in carding machines. It is the chief object of the invention to devise a driving mechanism for such a roll which can be manufactured economically and can be installed witha minimum of labor.

The nature of the invention will be readily understoodv from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims. In the drawings, I Figure 1 is a side view of a portion of a carding machine equipped with a mechanism embodying this invention; and

Fig. 2 is a plan view of apart of the machine shown in Fig. 1.

In the drawings the main cylinder of the machine is indicated at2, the leader or licker-in at 3, and certain of the flats at 4. 1

The cylinder 2 is mounted. on the main shaft 5 of the machine and this shaft is pro- 'vided with fast and loose pulleys 6, and 7,

respectively. The fast pulley 6, in addition to having a face to receive the main driving belt, is provided with a peripheralflange 8 which is grooved to form an auxiliary pulley adapted to receive a round belt. Normally this auxiliary pulley 8 is not used, but it is provided for the purpose of affording a convenient means for driving the grinding roll which is used in surfacing the card clothing on the main cylinder 2. The con struction so far described is substantially like that of a common commercial type of carding machine.

The stripper roll is indicated at 10, and it is supported on a shaft 12 which is mounted above and slightly to the left of the lickerin, as shown in Fig. 1. This roll is supported in two bearing brackets which are bolted to the machine frame, one of these brackets being shown at 13, Fig. 1.

The driving mechanism provided by this invention comprises a small gear or pinion 14 secured fast on the stripper roll shaft 12. Another gear 15 meshes with and drives the gear or pinion 14:. Both of these gears are completely enclosed in a casing which comprises a main casing section 16and a removable cover 17 which is bolted or screwed to the main section 16. The gear 15 above mentioned is mounted on a shaft 18 which rotatably supported in the casing 16 and cover 17 and projects through the cover. A pulley 19 is mounted fast on this shaft outside the casing and is arranged to be operatively connected to the grooved pul ley 8 by means of a driving belt 20.

The stripper roll shaft 12 fits snugly in a hole formed through the main section 16 of the casing so that this entire casing may pivot 011 the shaft 12. Projecting from the upper side of the casing 16 is a plate-like extension 21 in which a slot 22 is formed, this slot being curved about the axis of the shaft 12 as a center. A bolt 23 projects through this slot and is threaded into the frame of the machine. It will thus be observed that the casing is supported partly by the shaft 12 and partly by the bolt The pivotal movement of the casing permits the adjustment of the tension of the belt 20 and the bolt 23 serves to secure the easing in various'positions of adjustment.

Under some circumstances it may be desirable to make this belt tightening operation automatic, and for this purpose a spring 24 may be positioned in the slot 22, bearing at one e'ndagainst the-bolt 23 and at its op- 'posite end against the end of the slot, the

pressure of this spring tending to tighten the belt 20, as will be obvious from an inspection of Fig. 1.

Usually in installing the device, one of the bolts which holdsthe bracket 25 in place is removed, and this bolt, or one like it but having a larger head, is inserted through the slot 22 and threaded into the hole from which it was removed, so that it is unnecessary to drill and tap a new hole in the frame of the machine. I

It will now be evident that this invention provides a very simple mechanism for driving the stripper roll 10. This entire driving unit can be manufactured very economically, and it can then be installed on the machine with very little labor. The fact that it utilizes the grooved driving pulley 8 with which the machine is already equipped is an important practical advantage since it avoids the necessity of providing and installing a separate pulley, which operation very likely would require the removal of the fast and loose pulleys 6 and 7 from the main shaft. The casing may be packed with grease to lubricate the gears and bearings, it completely protects the gears from fly, lint and dirt, and it also forms an effective guard to prevent the clothing of the attendants from being caught in the gears.

While l have herein shown and described the best embodiment of my invention that l have so far devised, it will be evident that the invention is not limited to embodiment in the precise form shown.

Having thus described my invention, what i desire to claim as new is:

1. In a carding machine, the combination of a stripper roll, a shaft for said roll, a gear on said shaft, a second gear meshing with the first gear, a pulley rotating with said second gear to receive a driving belt, and a support for said second gear mounted for pivotal adjustment about the axis of said shaft to adjust the tension of said belt.

2. in a carding machine, the combination of a stripper roll, a shaft for said roll, a gear on said shaft, a second gear meshing with the first gear, a pulley rotatable with said sec nd gear and adapted to receive a belt driven from the main shaft of the carding machine, a casing for said gears mounted for adjustment about the axis of said shaft, and means for holding said casing in differ ent positions of adjustment.

3. In a carding machine, the combination of a stripper roll, a shaft for said roll, a gear on said shaft, a second gear meshing with the first gear, a casing enclosing said gears and mounted for pivotal adjustment about the axis of said shaft, a second shaft supporting said second gear and mounted in said casing, a pulley mounted on said second shaft and adapted to be belt driven, and a spring tending to move said casing in a di rection to tighten said belt.

4. 1n a carding machine, the combination of a stripper roll, a shaft for said roll, a pinion on said shaft, a gear meshing with said pinion, a casing enclosing said gear and pinion,a second shaft rotatably mounted in said casing and supporting said gear, a pulley mounted on said second shaft and adapted to be belt driven from a pulley on the main driving shaft of the machine, said casing being mounted for pivotal adjustment about the axis of said stripper roll shaft to adjust the tension of said belt, said casing having an extension projecting therefrom, and means cooperating with said extension to hold the casing in different positions of adjustment.

A driving mechanism for the stripper roll of a carding machine, comprising a gear for driving said roll, a second gear meshing with the first gear, a casing for said driving gears, and driving means for said second gear, said casing having a part adapted to be secured to said machine.

(5. A driving mechanism for the stripper roll of a carding machine, comprising a gear for driving said roll, a second gear meshing w the .;rst gear, a casing for said gears, a pn ley rotatable with said second gear, and a projection extending from said casing and adapted to be secured to a part of the card in g machine.

7. A driving mechanism for the stripper roll of a carding machine, comprising a pinion for driving said roll, a gear meshing with said pinion, a casing enclosing said gear and pinion, a shaft mounted in said casing and supporting said gear, a pulley fast on said shaft, and a projection extending from said casing and adapted to be adjnstably secured to the carding machine.
