BLEACHERY REEL.

llpplieatibn filed November 17, 1924. Serial No. 750,43 5f relates to improvements in, reels for use inbleacheries, finishing rooms and the like andfparticularly for handling cloth impregnated with corrosive or and the main object of the invention is to provide reel with renewable blocks or bars, which reel may be adjusted toany desired width and equipped with blocks or bars having' any deslredshape of groove. A further object is to provide a split reel ily apliquids,

, plied to or removed from existing shafting.

A still further object is to provide a split reel with removable blocks or bars which may be taken apart for application to or removal from a. shaft without disturbing the adjustmentof the blocks or bars. 7 Still another object'is to provide a reel having metal spiders.

Various other ob' advantages of the oregoing and other 0a 'jects may be ascertained from the following i 1 subject of this invention comprises a air of similar, metal spiderseach divided into.

lustrate.oneembodiment of the invention,

' adjacent their outer description. V V Briefly described, the reel formingthe two or more parts releasably connected to gether so as'to permit attachment to or detachment from an existing shaft without removing the same from its bearings. Eachspider comprises a series of spokes terminatingin sockets to receive and hold blocks or bars 1 extending between i the spiders. These spokes are connected together in pairs extremities and clamping bolts are passed through the spoke connections -midway between the spokes and therefore midway between the blocks or bars carried by the spokes, whereby the clamping j efl'ect ofeach boltwill be equalized between theblocks or barssecured b y it and slight inequalities in the length 0 the blocks or bars compensated for. i

In the accompanying drawings which 11- ects, together with the j 7 tion to nected by such members,

each composed of a plurality; of parts, for exam le, of two parts 12 and 13 as illus trate joining. at a diameterof the spider and provided with flanges 14 for the sage'of bolts 15 to each spider together and to clamp the same P 5 secure the two parts of around a shaft. Each spider comprises an evennumber of. spokes 1t} radially arranged andv connected together in pairs adjacent their outer ends by rim members 17. The spokes of adjoining pairs are not connected, t' ere being open spaces 18 between the spoke pairs corresponding to the position of the rim members connecting the spokes ofeach pair. The outer end of each spoke is provided with a laterallyopeningsocket 19 to receive the end of a block or bar-20, the opposite end of which is supported in a corresponding socket of the other spider. Each of these sockets comprises a bottom wall 21 inclined with respect to the plane of the I spider, an outer wall 22 also inclined to the plane of the spider but in the opposite directhe wall 21,.and' a pair of side walls 23 adapted to embrace the end of a block 20. The bottom -walls 21 support weight transmitted through inclination is such thatthe "blocks 20 tend automatically to centre themselves between the two spiders, while the inclination of the outer walls 22 blocks against The walls 23 hold the blocks against movement out of their radial disposition and in the circumferential direction of the spiders; Clamping bolts 24 pass through the rim members 17 midway between the spokes conwhen the bolts are tightened the load' imposed thereby is distributed equally between the blocks carried by the pair of spokes.

is such that they hold the removal radially outward,

with the result that p the blocks, and their i The lack of connection 'between'the spoke pairs at their outer. ends enables this effect to be obtained and also makes it possible to take advantage of the elasticity or flexibility of themetal of the spokesto compensatefor any slight inequality in the blocks.

s The ends and inner edges 25 and 26 respectively of the blocks are shaped to conform to the inclinationof the walls 22 and 21 respectively, regardless of the length of the blocks between. spiders or to the shape of the groove 27. (if any), in the blocks.

Figure-2 shows a short block with a narrow V-groove while Figure? shows a longer loo length of'the 7 block with a wide V-groove, and Figure at a block with a. tiat-bottom groove. It will be obvious that in each case the end and inner edges of the blocks are identically shaped where they engage the spiders, and also that the spiders themselves are identical. In short, the only alteration necessary to a"- commodate the reel to blocks of any desired shape or length is the employment of clamping bolts of suitable length.

A reel constructed according to this invention may obviously be separated diametrically for attachment to or remova from a shaft without any disturbance of the clamping bolts and block Vvhen it desired to renew the blocks in a reel, either to replace those worn or broken or to insert blocks of an entirely diticrent shape, it not necessary to remove the reel from its supporting shaft but merely to loosen the bolts 15 so that the spiders may be moved apart on the shaft for the release of the blocks and to permit the insertion and clamping in place of other blot'ks. A considerable economy will result from the use of such reels, as reels which are not in use may be readily moved to another part oi the mill for use or may be altered as to width and shape of groove merely by the insertion of new blocks without the necessity of purchasing a complete new reel. Should any part of the spiders become broken a maximum of only one-quarter of the reel spider need be replaced, owing to the use of separate and divided SPldk'liS at the two ends of the reel; and the amount of replacement may be materially reduced by increasing the number of parts into which each spider is divided.

While the invention has been reterred to and described only as a. bleachery reel, it will be understood that the same principles of construction may he applied to other types of reels as well as to the construction of winding drums, inserted toothed gears and other devices. It will also be under stood that alterations may be made in rarious details of the construction, such as the shape oi the socket members, without in any way departing from the spirit of the invention, and therefore all such modifications as fall within the scope of the appended claims are included in and form a part of the invention.

Having thus des "ribed my invention, what I claim is 1. A device of the class described comprising a pair of similar spiders each having an even number oi arms, rim members connecting the arm in pairs adjacent their tree extremities, members connected between corresponding arms ofthe two spiders, and bolts passing through the rim members intermediate the arm and clamping said members between the spiders.

2. A device of the class described comprising a pair of similar separable spiders each divided radially into a plurality of parts. means to clamp the parts together about a shaft, removable tooth members extending between the spiders, and bolts passing through the spiders and releasably clamping such tooth members in place.

3. device of the class described comprising a pair of similar spiders each div ded radially into a plurality of parts, m ans to clamp the parts about a shaft, rim members connecting the spider arms in pairs adja cut their peripheries, members disposed betnren iorresponding arms of the two spiders, and bolts passing through the rim members intermediate the spider arms, and clamping said members between the spiders.

+2. A. device of the class described comprising a pair of similar spiders, sockets at the extremities of the spider arms, members extending between the spiders and supported at their ends in said sockets. each socket including a pair of side walls to embrace the sides oi the contained member, and an end vxah shaped to hold the contained member against movement radially away t'rom the spider, rim members connecting the spider arms in pairs adjacent the sockets thereof, and bolts passing through the rim members of lnrth spiders intermediate the arms, each 0? r-raid bolts serving to clamp two of said members between the spiders.

:3. .t device of the class described compris..-. a pair of spiders each radially divided into a plurality of parts each having an even number of arms, means to clamp said parts together about a shaft, rim members connecting the spider arms in pairs adjacent their extremities, the arm pairs being entirely separate at their extremities, sockets at the extremities of the arms, bar, block or tooth members extending between the spiders and entering at their ends into said soclu .1. bolts passing through the rim members ot both spidersmidway between the arms connected thereto and clamping the bar, block or tooth members between the spiders.

6. in a. device of the class described a body having radiating arms at opposite ends thereof, rim members connecting the arms at each end in pairs adjacent their extremities, members inserted between corresponding arms of the two ends of the structure, and clamping bolts passing from end to end of the structure through the rim members intermediate the connected arms, whereby each bolt serves to clamp two of said members and to flex the arms of the structure as necessary to distribute the clamping load equally between the two members clamped.

In witness whereof, I have hereunto set my hand.
