. 60mins." (o1. 139 -304)v This invention relates to improvements in nar. row ware looms and it is the general object of the invention to provide improved means for mounting the cloth roll supporting shafts so they may be readily applied to and removed from the loom. Many narrow ware looms attain such a length as to make desirable intermediate supports or frames between the loomsides for the take-up and cloth roll'mechanisms. In such looms the cloth rolls are ordinarily mounted on several aligned shafts which are supported by bearings carried by the intermediate frames, but in the past'these intermediate'bearings have been of complicated construction involving several parts and necessi tating considerable labor to remove the shaft sections for the'purpose of unwinding the cloth andv then returning the shaft sections to the loom.

It is animportant object of the present invention to provide a bearing for twoadjacent ends of cloth roll shafts mounted on an intermediate support or frame and endwise motion relative to the shafts bya single retaining means carried by the intermediate frame. The bearings preferably have non-circula'r frustro-pyramidal cups or the like to'receive similarly formed ends or sections, and the cups are so formed as to free their gudgeons readily whenthe opposite end of the shaft is swung forwardly.

The cloth "rolls of narrow ware looms may either be loose on their supporting shafts and be turned by a belt or the like turned from a loom shaft, or they may be equipped with a friction drivefor their supporting shafts to'be turned as the latter are rotated. When the latter ma'nner of driving the cloth rolls is utilized a gearing mechanism is employed at eachfend of the 100m and half of the aligned shafts are driven from one end and the other half from. the opposite end. It is a further object of1the invention to mount the adjacent ends of shafts driven from opposite ends of the'loom in a central bearing made of two saddle or bearing parts which are alikelone part for each shaft end, and clamp the two parts together and to an intermediate frame. In carrying out this feature of the invention each half or part of the central bearing will have a gudgeon rotatable in the center intermediate frame and another part formed as an open slotbearing to permit forward removal of theassociated shaft.

. With theseand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts hereinafter described and set forth.

" In the accompanying drawings, wherein a conheld in position against gudgeons of the shaft front of the shaft 28.

Fig. 6 is an enlarged horizontal section on line 6- 6, Fig. 1 showing a bearing so constructed as to afford driving relation between the adjacent ends of two cloth roll shafts, and

Figs. '7 and 8 are vertical sections on lines I---! and 8-8, respectively, of. Fig. 6. 7

Referring particularly to Fig. 1, the loom has at the ends thereof primary loom frames [0 between which are located five intermediate frames l-l-l5. These frames may be held in fixed position in any approved manner as is customary in the manufacture of narrow ware looms of considerable width.

Each of the several webs or' fabrics 20 is wrapped around a take uproll 2| and then leads to a cloth roll 22. As indicated in Fig. 1, the loom is considered as being divided transversely into four sections I, II, III and IV, and the cloth rolls of these sections are mounted on

cloth roll shafts

25, 26, 21 and 28, respectively. These shafts'are aligned lengthwise of the loom and the cloth rolls are driven frictionally by their respective shafts and tend always to turn a little faster than is required to take up the cloth delivered to them by their take-up rolls.

The loom has two take-up mechanisms 33 and 3! located respectively at the left and right ends thereof which-drive

gears

32 and 33, respectively. Gear 32 is secured to shaft25 and gear 33 is secured to shaft 28 As shown in Fig. 4 the shaft 28 has secured thereto a collar 35 which engages the inner or left end asfviewed in Fig. 1 of a bearing 36 on frame 5 having upper and

lower arms

37 and 38 which define between thema forwardly openingslot bearing 33 for shaft 28. The latter extends through the bearing slot 39 so that the gear 33 may be attached thereto, and is normally held in the position shown in Fig. 4 by a removable pin ill passing down through the arms 3! and 38 in I When it is desired to move the right end of shaft 28 forwardly the pin til is cups 48 and 49, respectively, which are preferably.

frusto-pyramidal to receive. similarly formed gudgeons 50 and on the shaft se'ctionsi'tfand 21, respectively.

A p ositioning screw 52 is tapped through the.

forward part of the intermediate frame J5 and extends into a slot 53 formed peripherallyin the bearing 45 to limit motion of .the latter transversely of the frame 14 and longitudinally of the adjacent shaft sections. 48 and 49 are coaxial soithat the shaft sections 21 and 28 are held with theiraxes. aligned.

When theright end of shaft 28 .ismovedforwardly in slot 39 as already described the gudgeon 50 because of its shape will be abletounseat itself readily from its bearing-48 .in the collar 45 without cramping and without subjecting. the collar to any strain which might break it. Likewise, after the cloth hasbeen removed from the rolls 22 the shaft28 can be replaced first by inserting its gudgeon 50 into the bearing 48 and then moving it endwise. to thexleft, Fig. 1,

until the collar is against the intermediateframe ll, after which. the shaft will beiinserted into its end bearing and pin replaced.

The left end of shaft 25 and .theadjacentends of this shaft and shaft 26 may be mounted in a manner similar to that already described for the shaft sectionsZ'l .and28. The two aligned shafts 21 and 28 will be drivenby gear 33, and in like manner the aligned .sha ft sections 25 and 26 will be driven by gear. 32.v

The adjacent ends of shafts. .26. and 21' are mounted for rotation asshown in Figs. 2 and-3. The intermediate frame l3 has drilled therethrough a hole 60 serving as a bearing for shaft supports or saddle bearings v6| .and62, see Fig.

'3, which collectively may be consid'eredas acen tra-l bearing. The two saddles GI and- 62 are alike but willbe described as two separate parts.

The saddles BI and 62 have

slot bearings

63 and 64,. respectively, opening forwardly for reception of their associated shaft sections and saddle 61 has .a gu'dgeon .65 extending into one sideof bearing 60 and saddle 62 has a gudg'eon 66 fitting into the other side of the bearing.

The gudgeons .65 and .66 have parallel walls 61 and 68, respectively, extending along .one side of their

respective slots

63 and 64. .A clamping screw 69 extends through wall 68 and is tapped into wall 67. The bearing members GI and 62 have shoulders 10 and II, respectively, which can be and preferably are clamped tightly againstadjacent faces of the intermediate frame I3 by screw 69, the gudgeons 65 and 66' being spaced slightly to permit this clamping. The gudgeons project beyond their shoulders a distance slightly less than half the width. of" bearing 60',"S6E Fig. 3;

A screw 12 is tapped throughthe forward part of intermediate frame l3'in front of bearing 60 and is set up against flat surfaces 73, Fig. 2, on the two gudgeons to prevent them from turning in the bearing. 60 if it is not desired to rely wholely upon 'screw'69 toclamp the saddles in. place. The latter screw holds the The bearingcups saddles together so that the single screw 12 can engage both surfaces 73. Rods l5 and 16 similar to pin 40 may be provided for their corresponding shaft sections and ordinarily hold the shafts in their

open bearings

63 and 64. When removed these pins 15 and 16 permit forward removal of the-adjacent endsof .their co-rresponding shafts. a

The two saddles BI and 62 are alike and each "is symmetrical about a plane passing through the axis. of its gudgeon and also the longitudinal axis of its slot hearing. The shoulders are -formed like a horse shoe and their arm parts 11 andJBiWhi'chWdefineIthe slots are joined by a 'rounded part 7-9; see Fig. 2. As shown in Fig. 3

I one-of th-e saddles has been inverted with respect to the other. saddle in the direction of the length of the shafts 2T'and 28 before being fitted to the f-ramel3.

If it be desired to remove shaft section 21 forin'stance its pin 76 will'be-rem'oved and the left end thereof as viewed in Fig. 1 will be slid forwardly in. the open slot bearing 64 and their movedto the left so that its gudgeon 5| may free: itself readily from bearing 49 in the manher already described in, connection with the removal of shaft section 28.

It may not be necessary in all instances-to employ the set screw 12 as a supplement to the screw 69,, but it has been found desirable and whenused will not'require such a tight setting of :the screw 69. I

Fromxthe foregoing it *will be seen that the invention sets forth simple mounting means for aligned .clothroll shafts of narrow ware looms, the'bearing 45 as shown in Fig. 6 having tapered cups of non-circular cross section to receive similarly tapered non-circular shaft gudgeons which free themselves from their bearings when the opposite ends of the associated shafts are moved forwardly. It will also be seen that the center bearing is made of two saddle bearings which are alike and one of which is inverted with respect to the other. Each of the saddles or bearing members 6| and'62 has an open slot bearing extending along a gudgeon and wall positioned in the'bearing 6D. The walls 67 and 68 are formed as parts; of the gudgeons 65 and B6 and the two saddles are joined .by screw 69 passing through one wall and tapped into the other.

The coupling shown in Figs. 6 to. 8 is not claimed herein, but is disclosed and claimed in divisional application Serial No. 318,203, filed November 1, 1952.
