8 Claims.

This invention relates broadly to a friction device for filling carriers and particularly to a holder by means of which a friction device may be effectively held in a position to yieldingly engage that filling carrier located in a rotary hopper for car- 1 riers which is located in transferring position and the end that the filling will not unwind from the carrier and be subjected to the danger of breaking during the subsequent operation of the shuttle after the carrier has-been transferred thereto.

Another object of the invention is to provide a holder of novel construction by which the friction member of the device may be guided and adjusted together with a means for simultaneouslyclamping the friction member to the holder and the holder to asupport. f

Another object of the invention is to embody in the device a friction element of a character which will yield upon engagement with the filling to conform slightly to irregularities on the surface of the filling and which will not cause injury to the filling because of its engagement therewith. Still another object of the invention is to so' construct the friction devicethat it will also constitute an effective means for aiding and supporting a filling carrier while said carrier is located in transferring position. I

The invention consists in a friction device for filling carriers as set forth in the following specication and particularly as pointed out in the claims thereof.

Referring to the drawing:-

In the drawing, referring to Figs. l-to 4 inclu-- 5 sive, 5 represents a portion of the frame of a filling replenishing loom, t a lay, l a shuttle boxand 8 a shuttle positioned in said box. Mounted. upon the frame 5 is a stand 9 for a rotary bobbin disc I!) constituting a portion of a hopper III in which 10 a plurality of bobbins I2 constituting filling carriers are mounted in a well-known manner. Mounted on the stand 9 is a fixed transferrer stud l3 upon which is pivo-tallymounted a transferrer to which a transferrer dog It is pivotally attached at H. The dog It is adapted to be engaged by a bunter l8 mounted on the lay 6 to effect the operation of the transferrer I4 in a well-known manner and cause a bobbin l2 which is located in transferring position in the hopper ,II to be forced downwardly from said hopper into the shuttle 8. v i

All of the parts hereinbefore mentioned are old and their operation is well known in the art. It is also well known that portions of this mechanism, particularly the hopper l l, are caused to vibrate excessivelywith the result that therevis a tendency for the filling carriers l2 to rotate upon the portions of the hopper upon which th ey 30 are mounted, thereby causing the filling to un- Wind. When thishappens it is a common 00- currence after the filling carrier has been transferred to the shuttle for the filling thread to break when the shuttle is driven across the la'y'with 35 the result that the loom is caused to stop and production therefore is stopped until the loom is again started. j The friction device'of this invention is mounted upon an arm l9 which is rigidly fastened toflthe transferrer stud !3 by a set screw 20. A finger 22 constituting a top holder is rigidly secured in any suitable manner to a pivot member 2| which is mounted to rotate in abearing provided at the Mounted upon the opposite end portion'of the pivot member 2| from that upon which the top holder 22 is mounted is a friction device 23 embodyingtherein a sleeve 24 which is secured to the pivot member 2| by a cotter pin 25 and said sleeve 24 therefore rotates inunison with said pivot member. The sleeve 24 is recessed at 26 to provide a space for receiving a coil spring 21 surrounding'the pivot member 2! and one extremity of saidspring is connected to the arm l9 and the other extremity to the sleeve 24 in a manner to cause the top holder 22 to engage a stop provided upon the arm I I9 at which time the top holder will be located in a position to support the small end portion of the filling carrier l2 when said carrier is located in transferring position.

Mounted upon and. extending around the peripheryof thesleeve' 24 of the friction device 23 I is a holder 28 for a friction member 29. The

holder 28 is constructed as a band of sheet material and terminates at its opposite ends in parallel clamping portions 30 and-3l. The friction member 29 is adjustably mounted upon the clamping portion 3!! of the holder-2B-and is secured- I the holder havingparallel clamping portions M and=45 embodied therein between which a fric- 15 thereto .by means of a guide 33 and5bolt534, the

latter passing through the guide 33, through'a slot 35 provided in the friction member 29 and through slots provided thereforin the'clamping portions 30 and 3| of the holder 28, and saidbolt characteristics-of"rubber and is provided with a bevel surface 32 which is adaptedto underlie the filling-carrier H which is located in transferring position-an'd yieldingly engages the filling thereon in a manner to prevent said carrier from r-otat- -"'ing inithe hopper ll. The'friction member 29 will furthermore actas an aid in supporting the carrier l2 with which it contacts. It is desirable that the'materialof whichthe friction member '29 is constructed shallbe sufliciently flexible to conform slightly to the contour of the surface of thefillingwith which said member contacts to "the-end that-said member will effectively grip the I filling .material 'andthereby prevent the carrier fromrotating without injuring the filling.

' 'IhefrictionmemberZB is-adjustable toward and away from the filling carrier l2 with which 'it is adapted to contactin order that it may be correctly positioned with respect to said filling carrier. .The friction member 29 is positioned upon' theholder :28 by'means of the guide 33 which is constructed as an inverted U-shaped member, theparallel; arms of which engage the opposite edges of the clamping portion 30 of the holder, see Fig. 4, andwhen the friction member 50 "'29 is. clamped between the

guide member

33 and 21 areall old'and'well known'in'the art and that the top holder 22 tips downwardly to release the carrier [2 every, time -atransfer-is 'made. Applicant has utilizedthe pivot member 2| and sleeve 1 24 as a support forhisimproved friction device'23.

In' the operation of 'the loom, as the hopper H is rotated to successively position the filling car- I .Iriers l2 intotransferring position, the'surface of the filling. of thecarrier next to be transferred I will engage the bevelled surface 32 of the friction the friction device323 will rock in unison withthe top holder "22 as the latter releases thecarrier.

' curely to a sleeve' 24 by means of a bolt 4| and nut 42. It is evident that the friction member '46 may be adjusted between the clamping por- 10 tions 38 and 39 by moving said member 40 in-' wardly or outwardly as may be desired.

- In Fig. '7 still another modified embodiment of the invention is illustrated in which 43 comprises tion member 46 is secured. The holder 43 issecurely clamped to a sleeve 24 by means of a bolt 41' and nut 48. In securing this device to the sleeve to which it, is attached there will be a 20 clamping action tocompress the friction member a between the'portions 44 and 45, 'but'this action will not be as effectiveas in the other embodimerits of the invention-previously described. I I

' In all the embodiments of 1 the invention the- 25 friction members wmbe constructed of: a flexible material which will not injure'fthe filling when contacting therewith.
