Description

To all whom it 'may concern:
i Be it known that I, EDWARDVAN WINKLE, of
Paterson, in the'county of Passaic, and State of New EDWARD VAN WIN'KLE, or PATERson'NEW JERSEY.
Letters Patent Afa. 93,649, dated August l0, 1869.
IMPROVEMENT IN l FRICTION-BRAKES FOR. COTTON-LAPPING- MACHINES.
The Schedule referred to in these Letters Patent and making part of the Same.
Jersey, have 'invented a new and improved Friction- Attachrnent to Ootton-.Iiappers; and Iy do hereby declare that the following is a full, clear, and exactjdescription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichn Figure rl represents a front elevation, partly in section, of my improved friction-attachment to cotton-v lappers.
Figure 2 same, taken on the plane of the line x .v, iig. 1.
Similar letters of reference indicate like parts. The object of this invention is to produce an adjustable frictionattachment for thoser machines thronghwhich the cotton is passed, preparatory to its being carded, and which are usually termed cottonlappers.
The frictionattachlnents heretofore in usewere genorally but a system of weights, connected with the lap-roller; they were in no casev so xarranged that,I whatever may be the wear of the friction-surfaces, the degree of friction remains always the same.
lnKitsons patent friction-attachment, where two ,A
cheek-flanges, covered with leather, are used, the friction is, by short wear of the cheeks, so reduced as to produce laps much lighter' than those for which the apparatus was originally adjusted.
My invention consists chiefly inthe application of two conical tiiction-clutohes, one being stern-shaped, `and the other a'cup. The former is attached to the axle to be detained, and the other slides loosely on that axle, and is pivoted to a weighted arm.
lVhen this arni is not otherwise raised, itwill always automatically hold the clutches together, to have the friction applic-(hand as theweight is adjustable on the rod, the degree ot' friction can always beregu` lated. y
A, in the drawing, representsthe frame of my improved cotton-lapper. y B' Bare the two bed-rollers of the saine.
is a vertical transverse section of the- C is the lap-roller. It fits witli its ends under the books a a of the toothed bars D, as usual. Y
vThe toothed bars mesh respectively into pinionsb b that are mounted on a horizontal shaft, E, which shaft has its hearings in the frame A.
On the shaft E is mounted a somewhat conical wheel, F, the rirnrof which is covered with leather, or equivalent material.
G is a cup, sliding loosely on the shaft E, its inner diameter being as large as and shaped to correspond f with the outer surface of the wheel F, leather, or its and thereby also to the lap-roller.
If the 'friction-faces of the :clutches F G should wear, the degree of friction will remain the same, as the weight will have so much more downward play, to keep them together.
When, by means of a lever, J, the weight is raised, the friction is, of course, released.
The weight I is clamped to the lever H, in the desired position, by means of a screw, e.
The part G of the clutch may, if desired, be made stationary, and E sliding, instead of otherwise, if desired.'
I do not claim the conical frictionclutches perse, as I am aware thatthey have been used before; but
What I do 'clailmand desire to secure by Letters Patent, is
:The arrangement of the elbow-lever H and its.ad instable weight I, in combination with the male and female conesF Gr, Ysubstantially as shown and described, for the purpose set forth.v
