JAMES E. HAUG-I-ITON AND GEORGE BERRY, OF MANCHESTER, ENGLAND.

SHUTTLE IEOB- LOOMS FOB WEAVING.

Application filed March 15,

To all whom it may concern Be it known that we, JAMES EDWARD HAUGHTON, a British subject, residing at Higher Crumpsall, Manchester, county of Lancaster, England, and GEORGE BERRY, a British subject, residing at Chatham Hill, Manchester, county of Lancaster, England, have invented certain new and useful Improvements in Shuttles for Looms for Weaving, of which the following is a specification.

This invention relates to improvements in shuttles for looms for weaving and more particularly to self threading devices, or fittings for attachment to shuttles to enable them to be threaded by hand, in which a guide block is inserted in the shuttle head to direct or present the yarn or thread to the eye.

The invention consists in the particular construction of guide block hereinafter shown and described, characterized by three portions, all preferably formed integrally, viz: a horizontal or approximately horizontal portion, an inclined portion and a vertical apertured plate disposed in a vertical plane at right angles to the other two portions, and to the longitudinal axis of the shuttle, said apertured plate forming a tension and anti-ballooning plate in front of the yarn passage.

The invention will be fully described with reference to the accompanying drawings.

Fig. 1. is a plan of shuttle head partly in section with the guide block in position.

Fig. 2. is a side elevation of shuttle.

Fig. 3. is a section on line 33 Fig. 1.

Fig. 4. is a perspective view of the guide block and tension plate formed integrally.

Fig. 5. is a perspective view from the reverse side.

Fig. 6. is a perspective view of bottom member Z) with top member I) cut away.

Fig. 7. is a perspective view of modification of guide block B and tensionplate C formed in separate pieces.

The shuttle head A is cut away at a to receive the guide block B and tension plate C. The two portions 6, b are joined together at b forming at their junction an acute angle, the upper portion 6 being concave or curved and tapering towards its edges. The guide Specification of Letters Yatent.

block is set in the recess a in the shuttle head A with the lower portion 12 horizontal or approximately so and the upper portion 1) inclined to the vertical. The junction of the two portions?) 6 at 6 forms a yarn passage 6 which when in position opens into the eye a of the shuttle. In front of the guide block B a member or plate C is fitted in a vertical plane at right angles to the longitudinal axis of the shuttle. The portion or plate C has a hole to receive the Patented Aug. 15, 1922.

yarn or thread from the shuttle peg D and said portion or plate C is preferably formed integral with the portions (2 and 7). 'This plate prevents the yarn or thread from bal-' looning out of place between the two portions 1) b when threaded andalso assists in directing the yarn or thread bet-ween the two portions during the operation of threading the shuttle. It may be formed in one piece with the guide block B as shown in Fig. 4:,

. Or separate therefrom as shown in Fig. 7

The guide block B is disposed in the recess a of the shuttle A in such a position that the front of the yarn passage formed at the junction of the two portions 6 b is in line with the shuttle peg D and the back of the yarn passage 6 formed between the two portions extends or projects into the eye a in the side of the shuttle.

A pin E of wood or other material is inserted through the side of the shuttle and a metal pin F is inserted across the shuttle eye adjacent to the passage 5 The shuttle is threaded by passing the yarn around and under the inclined portion 6 and pulling it back parallel to the axis of the shuttle. This causes the 'yarnto pass through the hole in the plate 0 and between the portions 7) 6 into the passage 72 and be presented on the side. of the shuttle at the aperture or eye and the end can be readily pulled through. j

I hat we claim as our invention and desire to protect by Letters Patent is 2+ In a shuttle formed, with a recess-in its head, a guide blockarranged in said recess, comprising three portions, one approximately horizontal, the second inclined thereto, and having a depression at their junction sented to the eye, the third portion having an aperture r for the yarn and arranged in set our hands in presence of two subscribing front of the other two portions in a vertical witnesses,
