` KNOTTED NEEDLEWORK WITH TIED LOPSE Filed Mayr-w17,l 1945 Patiented sept. 3,1946 2,407,032

UNITED- STATES PATENT OFFICE lengths of uniform width and intended for sale by yards.

Clearly, instead of providing one loop in each square, two or three loops similarly knotted may be provided in each square, each loop knotted at both ends.

It is to be understood that the invention as here disclosed is not limited to the details here described and shown but that the same may be varied without departing from the spirit of the invention as defined by the subjoined claims.

I claim:

1. An article of manufacture from a single,

continuous strand consisting of a foundation Y,

continuous strand consisting of a foundation needlework of tightly knotted meshes forming open squares, running diagonally of said foundation and loops within certain of the squares secured between opposite knots in such squares, such open squares and looped squares being arranged in relation to each other to provide specific pattern bands running horizontally across said foundation.

4. An article of manufacture from a single, continuous strand consisting of a foundation needlework of tightly knotted meshes forming open squares, and loops within certain of the squares secured between opposite knots insuch squares, such looped squares being arranged in uniformly spaced bands running across said foundation.

5.,An article of manufacture from a single, continuous strand consisting of a foundation needlework of tightly knotted meshes forming open squares, running diagonally of said foundation, and loops running vertically of said foundation within certain of the squares secured between opposite knots in such squares, such open squares and looped squares being arranged in relation to each other to provide specific patterns.

simultaneously contracting the latter on its shaft.

Figure l discloses a further modification which consists in providing the bushing 4l with an annular shoulder adjacent one end, against which the ange i2 bears When the bolts 43 are rotated to draw the hub Ml and ange ft2 together to tighten the sleeve on the shaft. This iorin does not possess the pulling feature.

Figure 1l is identical in all respects to Figure l0 except that the sleeve 65 is provided with an annular recess at a point spaced from an annular shoulder adjacent one end to receive a snap ring 4s which latter affords a stop for the flange 47 when the bolts 48 are reversed to move the flange and hub 43 apart in the operation of removing the sleeve from the hub.

Figure l2 illustrates a simple form of the invention wherein the ange 5l] bears directly against the end of the adapter sleeve 5| when the bolts 52. are rotated to advance the hub 53 and nange 5d towards each other to contract the 5l on its shaft. This form does not include the retracting feature.

Maniiestly, the construction as shown and described is capable of some modification and such niodication as may be construed to fall Within the scope and meaning of the appended claims also considered to be Within the spirit and intent of the invention,

W hat is claimed is:

l. A sheave comprising an inseparable hub provided with a tapered bore and an annularly recessed face, a split and correspondingly tapered sleeve mounted in the bore of said hub and having a shouldered, extended end, a series of relatively spaced flange segments on the extended end of said sleeve, a flange ring having correspondingly spaced ilange segments on its inner surface adapted to enter between the segments ci said sleeve and repose operatively in alignment therewith, bolts passing through apertures in said ring and entering said hub and effective, when advanced, to draw said ring into the recess of said hub and to simultaneously contract said sleeve, said bolts being likewise effected, when reversed, to retract said ring and sleeve by contacting the segments of the former with those of the latter to release said sleeve for expansion.

2. A sheave wheel and mounting including a body having an integral and internally tapered hub provided with an annular recess surrounding its bore, a sleeve split longitudinally at one point and of otherwise unbroken continuity and Whose effect a drawing together of said flange and hub and consequent contraction of said sleeve.

3. A sheave and mounting including a body having an inseparable hub provided with a conical bore, a single piece, split sleeve having a .substantially thin wall and a tapered exterior disposed in said bore, circumferentially spaced segments on one end of said sleeve, a flange ring connected to an eytended end of said sleeve, a series of spaced lugs on said flange ring for interlocking engagement with the segments of said sleeve and means for moving said flange ring in relation to said hub to effect corresponding movement and resultant contraction and expansion of said sleeve.

4. A wheel and adapter mounting including a body having an inseparable hub provided with a tapered bore, a'split bushing in one piece having a substantially thin, resilient wall, and disposed in said bore, a flange ring embracing an extended end of said bushing, means on said sleeve and on said flange ring cooperating to effect interlocking relationship of said sleeve and flange ring, bolts passing through said flange ring and entering said hub and adapted, when rotated, to relatively move said hub and flange ring to eiect contraction and expansion of said bushing.

5. A sheave comprising an integral and interiorly tapered hub, a sleeve of resilient material, split longitudinally at one point and disposed in said hub, a ring releasably mounted on an extended end of said sleeve, radial, circumferentially spaced segments on said extended end of said sleeve, spaced lugs arranged on said ring to effect interlocking relationship of said ring and sleeve and means connecting said ring and hub for moving said ring in one direction to effect contraction of said sleeve and in another direction to release the same to its own inherent resiliency for expansion.
