A two-piece saddle for-spinning frames is, of course, not newsin the art nor is itnew 5 to provide fol-longitudinal adjustment of one saddlemember with reference to the may be shifted to heeen er ll ii lon -fiber we ho wise old 1 l i l he same saddle parts. being ferthree rolls a is the case where sh nrt-fihered staple is beinr; spun. In devices of this character, partie- 6 ulurly of the t\\- '-o-pieee tylpe, it is freonientli, meeessary -to readjust the asaddle from three-roll contact to a tw 0-r0ll. contact and as the operatives are generally of fit class who ai-e-liahleto make. errors in t-he adjust- -'ii'ie'its, it: is a common ecenrrenceyfor. the.

SflCld les to be improperly plzicedon some of the rolls of i spinni'ngframe. Further more, in changing one-Saddle member with reference to the other in longitudinal ad 7 justinent, the tensionw -light must'be raised :ii'u l='th e topsedrlle member moved in order to at the lower saddle member; which stradtllest'nwb of the rolls. li vhe'refthe sad-1 dles are-inztde in two. parts'the operator is further liable to dropthe'lowersacldle mem-' her =ii1uttanntingto raise the upper member ski and make the necessary change for adjustment.

It one (tithe primal objects of the pres 35 (Ht invention to provide-in conjunction with all of the ordinary well. known longitudinal .adjustingfeatures of 2; two-piece saddle, :1-

connecting device between the saddle parts so that one ennnothe inadvertently dropped when .tin-,=other is raised and so that there will lieone'of two positionsto which the lowerszultlle member may be shifted while still attziehi-il to the top siuli'ile member. 11011 the operative wishes to change fii roll, it is only ni' cessary to raise the weightbrought into action. This is all accomplished without any liability of dropping one or the other of the members of the saddle and insures proper positioning of the saddle members.

Inthe accompanying drawings, 1, 2 and 3 denote the top rolls and 4, 5, F.- the corresponding drawing rolls of a given set upon a spinning frame. These are suitably mounted in. bearings not specifically shown herein. The rolls 2, 3 represent the back-rolls and 1 the forward roll of a set. Upon the back rolls 2, 3, as illustrated in Fig. 1, rests the saddle member 7 and this is provided with a bearing surface 8 for the roll 3 and a surface 9 for the roll 2. The upper portion of the saddle member 7 is channeled as at 10 and into this channel projects a rib 11 formed on the under side of the tail of the top saddle member 12. This saddle member 12 has a bearing surface 13 for the front roll -1.- The channel 10 and rib 11 form a convenient means for preventing lateral separation of the saddle members and the shoulders 14, 15 at either side of the rib 11 are formed to extend beyond theside walls'16 of the rib 11 and overlie the walls 14, 15, of the channel 10.

The upper saddle member 12 is provided with an adjustable plate 17 which may be moved along' t;heupper side of the member 12 and secured in place by a suitable screw or other clamping device 18. The tension 7 stirrup 19 rests upon the forward end of the plate 17 and is held against longitudinal movement thereon by the up-turned end'20 and upset lug 21.

Between the top saddle member 12 and lower saddle member 7', there is arranged a '40 Figs; 1 to 5 of the drawings, consists of a hinged connection which, as illustrated in surfaces 9, 8 will register with the rolls 2 and 3, As the lower member is shifted rearwardly, it may be swung until a surface 8 registers with the roll 3 and thereupon the 'roll 2 is cleared. It will be seen from this that by raising the upper saddle member 12 a slight distance the lower mem her 7 maybe swung backward and forward to a position for engaging both the rolls 2 and 3 for spinning a short-fibered sta le or to a position engaging simply the bac roll 3 forspinning long-fibered. staple and that during this shifting, there is no liability of dropp ng the lower saddle member. In Fig.

venient means of forming the necessary I hinged joint between the two parts of-the saddle and insures freedom from cramping as the parts are assembled, inasmuch as the U-shaped wires may be driven down to the .ends of the small metallic tubes-without cramping against the sides of the saddle members.

In Fig. 6, in lieu of using the tubes, a pair of connecting members 27 are illustrated, each having a long arm 28 which may project through the perforation of one saddle member and be riveted down-as at29 and with its opposite end in the'form of va short parallel pivot 30. The-use of thissort of connection necessitates two perforations in each of the saddle members. i

In Fig. 7, there is illustrated a. form of connecting hinge which is simple and most efficacious and is arran d entirely within the structure of the sadd e-blocks. This consists of a link 31 havingan elongated perforation 32 at one end and a pivot perforation 33 at the opposite end. The central portion of the lower saddle member is grooved out as at. 34 from the. top and the lower side of theupper saddle member is grooved out as at 35 from the bottom. The link 31 is inserted in the grooves and pins 36, 37 are passed through the respective saddle members engaging the perforations 32, 33. In this form offlthe device, it will be noted that the hinged joint is formed interiorly of the structure where it is free from liability of becoming foul with lint or dirt and where it is not likely to be disarranged.

Of course, it is quite immaterial what extwo saddle parts so long as they are so hinged together that without transposln act form of connection is made between the either of the parts, one may beswung wit 1 reference to the other to adjust, as may be desired for two or three rolls or more, as the case may be.

It will be observed that there is no change in all the advantageous features of a saddle block which embodies relative longitudinal adjustment, insurance against transverse displacement and proper tensioning. With all these features present, there is the additional advantage of being able to shift and adjust the members. relatively to each other with precision and without liability'of dro ping and nus-placement of. either' of t e mem ers.

In practice, it is preferred to make the saddle members 12 and 7 from a treated fiber which has a homogeneous character'and is self-lubricating as to its entire structure but, of course, the adjusting feature may be applied to any desired form of two-piece saddle.

What I claim as my invention and desire to secure by Letters Patent is:

A saddle for spinning frames comprising a top'saddle and bottom saddle adjustably mounted with reference to each other and permanently interconnected by a link member pivoted to each saddle member whereby one saddle member may be shifted longitudinally into either one of two positions for adjustment with reference tothe other without disengagement of the parts.

2. A saddle for spinning frames comprising two parts having free longitudinal movement with reference to. each other and a link pivotally connected with both of said parts, though permitting longitudinal 'adjustrnent thereof as one is swung with reference to the other, said connecting link determining the amount of adjustment between the saddle parts as they are relatively moved into either one of two positions of adjustment.

3. A saddle for spinning frames comprising two parts having interengaging members between the saddle parts permitting longitudinal adjustment thereof, recesses in the meeting engaging portions of both parts and a pivoted link arranged in said recesses and pivotally connected to both of the saddle parts, though. permitting longitudinal adjustment thereof into two definite positions as one is swung relatively to the other upon the pivoted link.

4. A saddle for spinning frames comprising two parts, one normally resting upon the other and relatively adjustable into either one of two positions, recesses in the engaging portions of both parts and a pivoted link arranged in said recesses and pivotally connected to both of the saddle parts, though permitting longitudinal adjustment thereof as one is swung relatively to the other upon the pivoted link.
