SLUBBER OIt FLY-FR AME.

To all whom ct may concern:

Be it known that I, MALoomr CAMPBELL, of W'oonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Slubbers or Fly-Frames, of which the following is a specification.

This invention has relation to spinning machines, and more particularly to fly frames or slubbers.

It has for its object to provide an im proved and simple mechanism for transmitting power from the compound to the bobbin driving shafts, so that they will be rotated evenly and without variation or lost motion during the traverse of the bobbins. To this end, I employ a sprocket chain for transmit ting power from the compound or driver to an intermediate shaft arranged in parallelism with the bobbin shafts, and I mount said shaft in a radius arm whose axis of oscillation is coincident with the axis of one of the bobbin driving shafts. A. gear on the intermediate shaft intermeshes with and drives a gear on one of the bobbin shafts; and the chain is kept taut by any suitable means as by the tension of a spring which exerts its stress upon the radius arm.

Referring to the accompanying drawings, Figure 1 represents a portion of a slubber embodying my invention. Fig. 2 represents a front elevation of the same. Fig. 3 represents a plan view of the mechanism which embodies the invention. Fig. 4: represents a section on the line 4E4L of Fig. 1. Fig. 5 represents a section on the line 55 of Fig. 4.

Referring to said drawings, a indicates the driver from which power is transmitted to the bobbin shafts. It is illustrated as a shaft having thereon, a sprocket wheel 6. The bobbin driving shafts are indicated at c and (Z respectively, and they together with the rail 6, are reciprocated vertically upon guides e by the usual mechanism. To distinguish these two shafts, I designate the shaft 0 as a rear shaft and the shaft (Z as the front shaft. On these two shafts c and (Z, are secured equal gears f and g, which intermesh as shown in Fig. 1, so that said shafts are caused to be driven one from the other in opposite directions.

h indicates a cylindrical bearing in which the front bobbin driving shaft is journaled, said bearing having a flange h by which Specification of Letters Patent.

it is attached to the rail 0 as shown in Fig. 4. Upon this hearing is journaled a hub j of a radius arm j, said arm having at its end lateral tubular extensions 9' to constitute a bearing for what I term an intermediate shaft ]c. Upon one end of this shaft 70, is j ournaled a pinion 7a which intermeshes with and drives a gear or pinion d on the shaft (Z. On its opposite end, the shaft 70 has a sprocket wheel m between which and the sprocket wheel I) is stretched an endless sprocket chain a. A coiled spring 0 of sufiicient strength is placed upon the hub j of the radius arm, one end thereof being secured to the flange it of the bearing, and the other end, which is extended, being passed through an aperture in the web of the radius arm as shown in Fig. 2. This spring serves to take up any slack in the sprocket chain and to hold it taut, and at the same time it permits said radius arm to swing about its axis of movement as the bobbin rail is reciprocated vertically. By mounting the radius arm on an axis coincident with the axis of the front bobbin shaft, I am able to gear the intermediate shaft directly to said front bobbin driving shaft by means of the straight spur gearing and effect rotation of the bobbin shafts in the proper directions.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I declare that what I claim is:

1. In a spinning machine, a driver, a vertically movable bobbin shaft, a radius arm pivoted on the axis of said bobbin shaft, an intermediate shaft mounted in the free end of said radius arm, intermeshing gearing for transmitting power from said intermediate shaft to said bobbin shaft, and means for transmitting power from said driver to said intermediate shaft.

2. In a spinning machine, a driver, a vertically movable bobbin shaft, a radius arm pivoted on the axis of said bobbin shaft, an intermediate shaft mounted in the free end of said radius arm, intermeshing gearing for transmitting power from said intermediate shaft to said bobbin shaft, a sprocket wheel on the driver, a sprocket wheel on said intermediate shaft, a chain connecting said sprocket wheels, and means for'maintaining said radius arm in a position to take up the slack of said chain.

3. In a spinning machine, a'driver, a vertically movable bobbin shaft, a radius arm pivoted on the axis of said bobbin shaft, an intermediate shaft mounted in the free end of said radius, arm, intermeshing gearing for transmitting power from said intermediate shaft to said bobbin shaft, a sprocket Wheel on the driver, a sprocket Wheel on said intermediate shaft, a chain connecting said sprocket Wheels, and a spring exerting a tension. on said radius arm to take up the slack in said chain.
