Description

To all whom it conce/ mi ANTHONY A.' BENNETT AND GEORGE VINE; or NORWALK, CON- Y NECTIOUT.

IIMPROVIEBIIEINTv IN CARDING-MACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that we, ANTHONY A. BENNETT and GEORGE VINE, both of the town of Norwalk, county o f Fairfield, and State of Connecticut, have invented a new and useful Improvementin Carding-Machines;

and we do hereby declare that the following is a full `and exact description thereol'reference being hadto the accompanying drawing, and to the letters of reference-marked thereon. i

lllhenature of our invention consists in the arrangement of machinery for the purpose of giving the doier a slow and gradually-increasing speed in its revolutions,

for forming a wedge-shape felting cloth, for the use of pianos.

To enable others skilled in the arttomake and use our invention,4 we will proceed vto describe the same.

The drawing, iig. l, is a side view of a carding-maf chine with our improvements.

The cylinder A, dofier B, drum O, and'other corresponding parts, frame, &c., of the cardng-machine, remain the saine as usual.

On the 'end of the shaft E of the doiier B we-attach the eccentric' slotted gear-wheel D, and working in the same is the pinion-gear F.

This pinion-gear F islattached to the end of the vibrating rod or arm G, and is revolved by the belt H,

connected to the driving-pulley I, which connects with a pulley and belt on .the other side, to a pulley and belt on the main cylinder A.

A belt on the pulley of the `dofer drives the drum A(l with corresponding speed.

The lower end of the vibrating arm G works loose on the shaft M, and, by this combined movement, the

doier is revolved by the action of the pinion working on the large eccentric-gear wheel D, and, in consequence of the eccentricity of the same, the doer will have a slow movement when the pinion works on the large radius of the gear D, and with a gradually-accelerated speed as the pinion works down on the small part.

Differential speeds are lgiven by shifting the wheel D, by means'of the slot Nain the same.-

By this variable movement of' -the doii'er, the fleece 'arrangements for producing the variable revolutions of the doiier and drum, but to any equivalent devices for the same effect and purpose.

What we claim as'our invention, and desire to secure. `by' Letters Patent, is-

The arrangement of the eccentric revolving gearwheel D, pinion l?, vibrating lever or drum O, in com. bination with the main cylinder, driving-belts, and pulleys, or their equivalents, to give the variable. speed,l

in the -rnanner substantially-as and for-the purpose described. A

Norwalk, Connecticut, March 27, 1868.
