g a 01mins; (Cl.139 -"-251) This inventionrelates to a friction device for filling carriers, particularly that cariier located in a rotary hopper for carriers, which is-located in. transferring position and is next to be trans ferred to the shuttle. i I
The object of the invention is to provide a simple effective device for engaging the filling carrier which is located in transferring position and creating sufiicient pressure thereon to prevent said carrier from rotating in the hopper as a consequence of the vibration of the, latter, to the end that the filling will not unwind from the carrier and be subjected to the, danger of, b reaking during the subsequent operation of the shuttle after the carrier has been transferred thereto.
Another object of the invention is toembody in the device a. friction element of a character which will yield upon engagement with the fill ing to conform slightly toirregularities upon 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 device that it will also constitute an effective means for aiding in supporting the filling carrier mentioned, while said carrier is located in transferring position.
The invention consists in a friction device for filling carriers as set forth in the following specification and particularly as pointed out in'the claims thereof.
Referring to the drawing:-
Fig. 1 represents a vertical sectional elevation of portions of a filling replenishing loom including a lay having a shuttle mounted thereon, a hopper for filling carriers and a transferrer mechanism for said carriers, a friction device for filling carriers embodying my invention being illustrated associated therewith.
Fig. 2 is a plan view partly broken away and illustrated in section of a portion of the mechanism illustrated in Fig. 1 and including the friction device of this invention.
Fig. 3 is a perspective view of the friction device.
Like numerals refer to like parts throughout the several views of the drawing.
In the drawing, 5 represents a portion of the frame of a filling replenishing loom, 6 a lay, l a shuttle box and 8 a shuttle positioned in said box. Mounted upon the frame 5 is a stand 9 for a rotary bobbin disc l0 constituting a. portion of a hopper II in which a plurality of bobbins l2 constituting filling carriers are mounted in a wellknown manner. Mounted on the stand 9 is a from said hopper intothe shuttled; l
fixed transferrer stud [3 upon which is pivotally mounted a transferrer l4 provided with a downwardly-projecting arm I5 to which atransferrer dog I6 is pivotally attached at 11.. The dog I6 is adapted to be engaged by. a bunter l8 mounted on the lay- 6 to effect the operation ofthe transferrer I 4 in a well-known manner and cause a bobbin I2 which is locatedin transferring position i-nthe hopper ll tojbe forced downwardly All. of the parts hereinbefore, mentioned are old and their operation is well known inthe art. It is also well known ,thatportionsof thismechanism, particularly the hopper H, are caused to vibrate excessively with the result that there is a tendency for the filling carriers l2 to rotate upon the portions of the hopper upon which they are mounted, thereby causing the filling to un wind. When this happens it is acommon occurrence after the filling carrier has-been transferred to the shuttle for the filling thread to break when the shuttleis driven acrossthe lay with the result that the loom is caused. to stop and production thereforeis stopped until the loom is again started. W The friction device of this invention is mounted upon an arm l9 which is rigidly fastened to the transferrer stud l3 by a set screw 20. A
Projecting laterally from the periphery of the sleeve portion 24 of the friction device 23 is an arm 28 provided with a groove 29 therein in which a friction member 30 is tightly gripped between the opposite jaw portions of the arm 28. The friction member 30 is constructed of flexible re- The sleeve porin supporting the carrier with which it contacts.
It is desirable that the material of which the friction member 30 is constructed shall be sufliciently flexible to conform slightly to the contour of the surface of the filling with which said member contacts to the end that said member will effectively grip the filling material andthereby. prevent the carrier from rotating without injuring the filling.
It will be understood that the arm I9, pivot member 2|, top holder 22, sleeve portion 24 and spring 21 are all old and well known'in the art' I and that the topflholder 22 tips downwardly to made.
release the carrier l2, every time a transfer is Applicant has utilized the pivot member 2| as a support for his improved friction device 23'and has redesigned the sleeve portion '24 to include the gripping means 28 for the friction member 30. r r a In the operation of the loom as the hopper II is rotated to successively position the filling carriers I2 into transferring position; the surface of the filling of the carrier next to be transferred will engage the bevelled surface 3| of the friction member 30 and the latter will yield slightly and engage the filling with a'gentle flexing contact which will prevent the carrier from rotating and at the same time not injure the filling during the interval that-the carrier is located in transferring position and at thetime that the carrier is transferred to the shuttle. When the transfer is made the friction device 23 will rock in unison with the top holder 22 as the latter releases the carrier,
' and said friction device will act to guide the carrier during its transfer from the hopper to the shuttle.

In a filling replenishing loom the combination of a rotary hopper for filling carriers, a trans ferrer stud, an arm fast to said stud, and a flexible friction member pivotally mounted upon said 7 arm and adapted to tip downwardly thereon with each transferring operation, said friction member having a yieldable inclined friction surfaceembodied therein adapted to underlie and support the carrier next to be transferred and create a friction upon the filling wound therearound thereby preventing therotation of said carrier in said hopper, said friction member also acting to guide the carrier during its transfer from the hopper to the shuttle.
