WILLIAM J. HALL, OF PAWVTUCKET, RHODE ISLAND.

SPECIFICATION forming part of Letters Patent No. 767,750, dated August 16, 1904.

Application filed November 1, 1901. Serial No. 80,725. (No model.)

of Rhode Island, have invented a certain new and useful Improvement in Evener Mechanisms for Cotton-Openers or the Like, of which the following is a specification, reference being had therein to the accompanying drawing.

The objects of the invention are to simplify and cheapen the construction of evener mechanism and to produce an improved mechanism having a convenient arrangement of the parts thereof which shall render the same readily accessible for all necessary purposes and shall relieve all obstruction or concealment of the working parts of the machine.

An embodiment of the invention is represented in the accompanying drawing, which latter shows in elevation the said embodiment combined with certain parts of a cotton-opener or the like machine.

Having reference to the drawing, 1 designates a portion of the framing atthe feed end of a cotton-opener or the like machine,'2 a feed-roll, and 3 3 3, &c., a series of feed-plates above said feed-roll and cooperating there- With.

1 4 4E designate a train of gearing of usual or suitable character intervening between the feed-roll 2 and the shaft 51 of the upper cone 5 for the purpose of transmitting motion to the said feed-roll from the upper cone. The .lower cone is designated 6, the cone-belt 7, and the cone-belt shifter 8. A portion of the motion-transmitting train of gearing by which the lower cone is actuated is indicated at 81.

Instead ofbeing located at the side or end of the machine, alongside and beyond the machine proper, as ordinarily the case in practice, the cones 5 and 6 and cone-belt shifter 8 are arranged by me transversely of the machine and below the feed-roll 2. This reduces the amount of floor-space occupied by the machine, places the cones and cone-belt shifter in a less exposed position, gives access to the end of the machine, and is otherwise convenient and advantageous.

In connection with the plates 3 3 3, &c., I employ a scale-lever system at 9, the latter being arranged wholly above the feed-plates. Said system is of the well-known character, and various forms and arrangements thereof are employed in the art. At 91 is indicated portion of a rod intervening in customary manner between the inner mechanism and the main or weighted lever 10, pertaining to the said scale-lever syst'em. Said lever is located above the other portions of the said system. 101 is the weight that is applied to the outwardly-extending arm of the said lever.

In further conformity with my invention I connect the cone-belt shifter 8 to a rack-bar 11, sliding in a direction crosswise of the machine and lengthwise of the cones 5 and 6. The said cone-belt shifter and rack-bar are both located beneath the feeding devices. I

the scale-lever system. The pivotal support 1 12 of the quadrant is located beyond the corresponding side framing of the machine, and'rod 15 is located outside of said side framing. For convenience of adjustment the rod 15 is furnished with a yoke 151 at its upper end fitting the lever 10, and said yoke is equipped with an adjusting or set screw 152, making contact by its lower end with said lever. By turning said screw any desired adjustment of the cone-belt shifter relatively to the cones 5 6 may be effected.

I claim as my invention 1. In evener mechanism for cotton-openers and the like, machines, in combination, the feeding devices, the cones extending transversely across the machine below the said feeding devices, a cone-belt, the cone-belt 9 connected with said lever and depending therefrom, and the quadrant operated through the said rod and in operative engagement with the said sliding rack-bar to move the rack-bar and cone-belt shifter transversely across the machine, substantially as described.

2. In evener mechanism for cotton-openers and the like machines, in combination, the feeding devices, the cones extending transversely across the machine below the said feeding devices, the cone-belt, the cone-belt shifter located beneath the feeding devices and movable transverseh of the machine, the scalelever system located above the feeding devices and having the outwardly-extending main or Weighted lever, the rod connected with said lever and depending therefrom at the side of the machine, and direction-changing transmitting connections by means of which the vertical movement of the rod is converted directly into a movement of the cone-belt shifter transversely across the machine, substantially as described.

extending main or weighted lever, the rod connected with said lever and extending there from, the quadrant operated through the said rod, and the compound gear and pinlon 12, 13,

in operative engagement With the quadrant and rack-bar, respectively, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.

WILLIAM J HALL.
