SHUTTLE.

Application filed June 2, 1925. Serial No. 34,389.

This invention relates to an improvement in shuttles more particularly an improved construction of yarn guide eye through which the yarn from the shuttle package is drawn; and the object of this invention is to mount an eye in the shuttle with a cushioning material between the eye and its surrounding walls.

A further object of this invention is to support an infractible guide eye having a longitudinal or axially-disposed threading opening in the shuttle such that the same may be readily positioned and securely held and at the same time cushion the eye to prevent its being broken from the impact of the shuttle with its check in the loom.

A still further object of this invention is the provision of means to prevent the thread from being caught between the eye and the bushing in w ich the same may be mounted.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings,

Figure 1 is a plan view of a portion of a shuttle broken awa and showing in section the eye throug which the yarn is drawn.

Figure 2 is a side elevation of the same.

Figure 3 is a perspective view of a metallic bushing of the type used in automatic shuttles.

Figure 4 is a perspective view of a porcelain guide eye for insertion into the bushing.

Figure 5 is a sectional elevation showing the porcelain eye mounted in the bushing with the fingers of the bushing folded into notches in the guide eye.

Figure 6 is a perspective view illustrating one means of inserting an eye in the bushing by incasing the same in a tubular elastic member.

Figure 7 is a fragmental plan View of a hand-threading shuttle partly in section showing a porcelain eye as mounted in the shuttle by means of an elastic member.

Figure 8 is a side elevation of the same.

Figure 9 is a perspective view showing a porcelain guide eye as mounted in the bushing of the type adapted to be threaded into a hand-threading shuttle.

Figure 10 is a side elevation illustrating the elastic member as helically wound in a stretched condition about the porcelain guide eye which may be placed in the shuttle opening.

Figure 11 is a perspective View illustrating a porcelain guide e e with strips of elastic material indicate as placed longitudinally thereof.

It is found in the practical operation of shuttles for weaving of advantage to employ a porcelain bushing in the eye thereof through which the yarn is drawn, owing to the well known fact that the wearing life of an eye formed of this infractible porcelain material is more than double that of any other material that can be used for this purpose and is practically that of the shuttle itself as it will not score or groove by action of the yarn running therethrou h. 7.

In automatic shuttles where the tubu ar eye must be split along its side to permit thethreading of the yarn therethrough, it has heretofore been found to be impractical to use a porcelain eye therein owing to the fact that the impact of the shuttle in being checked in its flight when driven back and forth across the loom soon cracks or breaks this fragile porcelain eye to .such an extent as to render its use impractical in this style of shuttle. Therefore, to obviate this very serious difiiculty, I have positioned a cushioning layer of flexible material such as rubber or other suitable yieldable material between the eye and the walls of the opening in which the eye is set, which material serves to absorb the shocks and so efiectually prevent the orcelain e e from being injured by these s ocks to w ich it is subjected thereby prolonging its working life to substantially that of the shuttle itself.

Further, at the time of the insertion of the eye into the shuttle opening the rubber or yieldable material is placed under tension to reduce the thickness of its surrounding walls after which this elastic material' is released from this tension to permit it to thicken and be compressed and so yieldingly bind the walls of the eye in the walls of the opening to grip and so secure the eye in the opening without other fastening.

It is further found desirable to rovide fingers cut-from the stock of the bus ing to be bent inwardly into notches in the yarn guide eye to assist in holding the eye in its position in the bushing and also to form a guide to prevent the thread from catching between the eye and the walls of bushing; and the following is a detailed description of the structure embodying my present invention:-

With reference to the drawings, 10 designates an automatic shuttle which may be formed of any suitable material and which is provided with an automatic threading member ll'and a yarn package 12. In the forward end of this shuttle there is mounted in a recess 13 a bushing 14 of metal or any suitable material which is substantially circular in form and provided with a narrow threading neck 15 through which the yarn enters in the threading operation, and in order to prevent the yarn from grooving or scoring the bushing, I have mounted a guide eye 16 in this bushing by tensioning an elastic material 17 durin the positioning of the eye in the bushing w ereby the thickness of the walls of the elastic material is reduced and then the elastic material is released to expand and bind the eye in the bushing. This elastic material'may be in the form of a tube 18, stretched and drawn through the eye-receiving opening, as illustrated in Figure 6, or it may be wound helically about the eye as at 19 in Figure 10, or it may be used in the form of longitudinal stri s 20, preferably a plurality, as illustrate in Figure 11 or the elastic material may be in any other desired form, the elastic material in the first two cases being suitably cut away or severed to permit contraction of the elastic material to leave the threading opening 21 of the guide eye free for the threading of the yarn thereinto. It will be apparent that the elastic material will not only expand to bind the eye in its osition but will also form a cushion for t e eye to prevent its breaking upon the shuttle being checked in its fliglht. In order to more effectively secure t e eye in its position in the bushing the eye maybe recessed-or notched as at 22 and mto these recesses fingers 23 cut from the stock of the bushing are rolled or folded as at 24, the ends of these fingers being doubled under to protect them from engagement with the yarn.

In some instances, as shown in Figures 7 and 8, the orcelain member 25 is cast in the desired orm havin a slit 26 and is positioned directl in the s uttle without the use of a bushing eing secured therein by means of an expandible member 27 between the walls of the eye and the walls of the shuttle opening, in t e same manner as mounting the porcelain eye in the metallic bushing.

Figure 9 illustrates a porcelain eye 28 mounted in a metallic bushing 29 by means of rubber or other suitable expandible material 30 the same bein then adapted to be positioned in the hen -threading shuttle or the like in the usual manner.

It will be readily apparent from the above that I have provided a simple and practical means of inserting an eye of infractible material into a shuttle, by which construction the eye of infractible material is securely held in position and is cushioned against breakage due to the impact of the shuttle in being operated in a loom.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resortin to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:
