LEATHER FACING FOR CON-CLUTCHES.
Specification of Letters Patent.
lPatented May 22, 1917.
c Application filed J une v26, 1916.: lSeriali No.n 105,951.
To all whom t may concern.' .Y
Be it known that I, RUDOLPH C. JENSEN,
a subject of the King of Denmark', residing v at Springwells, in the county of Wayne and State of Michigan, have invented Vcertain new and useful -Improvements in Leather Facings for Cone-Clutches, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to the manufacture of leather facings, such as are used in friction drive clutches, and it is the object of` the invention, first, to lessen the cost,` and second, to obtain an improved construction.
In the present state of the art, it is usualV to provide cone clutches with leather fac? ings which form the friction element. Thisrequires the cutting of a strip ofleather of sufficient length to form an annulus when the opposite ends thereof are joined, and on account of the conical form the stripL must be cut on a curve. As a consequence, a large piece of leather is required for the forming of the strip and there is more or less waste in cutting. Furthermore, as the thickness of the leather is not absolutely uniform in all portions of the sheet, the strip will not be uniform in cross section.
With my improvement the cost of manufacture is greatly reduced by substituting for a long continuous curved stripl cut from leather stock a strip formed from a series of overlapped short pieces of leather that may be cut from scrap. The leather sections may also be arranged in slight angularrelation to each other, so as to produce the desired curve in the strip without any Waste in cutting.
In the drawings:
Figure l is a perspective view of a leather annulus embodying my invention;
Fig. 2 is a side elevation of a portion of the strip and Fig. 3 is a longitudinal section thereof. A A A2, etc., are leather sections, which may be cut from scrap, and which are pref-A erably of substantially rectangular form. These sections are assembled in overlapping relationto each other and are secured together bya suitable adhesive or leather cement. By arranging thesections in slightly angular relation, as indicated in'Fig. 2, the strip formed will be longitudinally curved, and when the endsare joined together will result in 'a conical annulus. @ne or both sides of the strip may then be trimmed so as to produce a continuous surface, as indicated at B Fig. 3. I prefer, however, to
only face one side of the strip in this man ner, leaving the working-or friction face of the notched form indicated at C, produced by the overlapping ends D of the sections. This will have the advantage of producing a more yielding action when the clutch is in operation, as the leather will be compressed and deflected laterally before attaining the maximum frictional engagement with the coperating member. 1
In use, the leather annulus is applied to 'Y the clutch, preferably to the male member thereof inv the usual manner, while the notched surface will frictionally en age the coperating clutch member to pro uce the desired result. ,c
What I claim `as my invention is 1. A clutch facing, comprising an annulus formed of a series of small sections of leather overlapping and secured to each l other.
2. A clutch facing, comprising a-n annulus formed of a series of small sections of leather assembled ,in overlapping relation and cemented to each other.
3. A clutch facing, comprising an annulus formed of a series of small sections of leather assembled in overlapping relation Vand secured to eachother, the successive sections being `in slightly angular relation to produce a curve in the strip and a coning of the annulus.
4. A clutch'facing, comprising an annulus formed of a series of small sections of leather' assembled in overlapping relation, formingV a notched surface constituting a yieldable friction face.
In testimony whereof I affix my signature.
lRUDOLPH c. JENSEN.
