YARN GUIDE FOR KNITTING MACHINES.

Application filed Kay 21,

Fig. 4 is a view of one of the guide tubes detached.

. In these drawings 1 indicates a yarn guide adapted to be attached to the reciprocating carrier barof a Cotton frame. Its lower end is split and-spring tempered. The opposing faces 2 of the lower split end of the yarn o guide are grooved as shown and these grooves have inclined bottoms resenting jointly a receiving socket formation which is flared towards its upper end. In this socket-like formation a yarn guide tube 3 is mounted. It is tapered to fit the recess between the ends of the split guide andas its upper end is of a diameter larger than its lower end, it will be retained in place merely by the rip of the

ends

4, 4 of the ggsplit member t ereon. It can not become displaced nor dislodged from between these ends by a lengthwise movement because of its upward flared formation or its eneral taper, it being understood that the said tube may be tapered from end to end or said taper may extend only part way of the length of the tube. In order to place the tube in position it is pressed laterally between the

jaws

4, 4 of the split member. These jaws will spring apart sufiiciently to allow the tube to be sna ped into place, and a suitable implement li e a pair of pliers may be employed to snap the tube into position. The

jaws

4, 4 have an enlarged recess between their upper ends at 5, rendering the jaws more resilient by reducing the thickness of the upper ends of said jaws.

There is a groove 6 extending vertically along the front face of the guide for the passage of the yarn to the tubular insert guide piece 3. This tubular member 3 projects below the lower end of its holder.

When a tube'3 becomes worn it is removed and its place is taken by a new tube. In placing a new tube in position it is forced 1927. Serial No. 193,279.

between the

spring aws

4, 4 by pressure exerted in a direction laterally of the main body of the uide. That is to say, the new tube is place sidewise against the old tube and when pressure is applied to the new tube 1t 18 force in between the jaws and the old tube is forced out from between the jaws.

The renewal can be made quickly, and no fastening means is necessary to hold the tube in place, thespring grip of the jaws and the tapered form of the seat between the aws being all that is necessary to insure the holding of the tube in place. At its upper end the tube abuts the shoulders 7 forming the upper wall of the socket or grooves between the

spring jaws

4, 4.

- In a previous form of guide,,a removable cylindrical tube has been em loyed which issoldered in place between at facedjaws. When this is to be renewed, the solder must be melted and thenew tube inserted and resoldered. This takes much time. Renewal of the guide tube is necessitated by the wear of the yarn. When silk is used the guide tube is soon out by the continued action of the silk yarn thereon and renewal of the tube then becomes necessary.

I claim:

l. A yarn guide havin spring jaws, a guide tube snapped into p ace between said aws and sha ed to prevent endwise remova1, substantia ly as described.

2. A yarn guide having spring jaws with grooves in the opposing faces of said jaws, and a guide tube snapped laterally into place between said jaws and flared externaly to prevent longitudinal displacement or removal, substantially as described.

3. In combination in a yarn guide for full fashioned knitting machines, a member havng spring jaws with grooves in their opposmg faces, said grooves being enlarged at one point and presenting shoulders at their upper ends, and a yarn guide tube held between said jaws in the grooves and against the shoulders, and having an enlarged portion to fit the enlargement] of the grooves to prevent lengthwise dislod ment of the tube, substantially as describe 4. A yarn guide having spring jaws, a guide tube snapped into place between said jaws, said jaws and tube having coacting surfaces shaped to prevent endwise removal of said tube in both directions.

5. A yarn guide consisting of a depending 1!.

plate like member comparatively thin throughout its lower portion and terminating in spring jaws at its lower end, and a guide tube located between said spring jaw-s and disposed with its axis intermediate the front and rear faces of the jaw portion of said thin plate-like member.

6. A yarn guide having spring jaws havnig a normal tendency to spring towards each other, a guide tube between said jaws,-

with means for holding said tube in said jaws against longitudinal displacement in either direction.

In testimony whereof, I allix niy signature.
