SHUTTLE FOR LOOMS.

Specification of Letters Patent.

Patented Sept. 10,1912.

Application led November 26, 1909, Serial No. 530,067. Renewed February 20, 1912. Serial No. 678,957.

To all whom it may concern:

Be it known that we, ADoLPH VVIDMER and SAMUEL VIDMER, citizens of the United States, residing in Paterson, Passaic county, New Jersey, have invented a certain new and useful Improvement in Shuttles for Looms: and we do hereby declare the following to be a full, clear, and exact description of the invention, `such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to loom shuttles and particularly to the means for supporting In one class of such shuttles, notably for narrow-ware looms, the quill is arranged on an axial support which is secured in the shuttle at both ends and is rotatable on its support so as to discharge the thread; usually this support takes the form of a pin which lits into a hole in the shuttle at one end and is suitably held at the other, and as the pin is bodily removable from the shuttle it is often lost and besides makes necessary some experience and skill in the assembling and disassembling of the parts.

Our object in the present invention 1s to provide a shuttle in which the axial support for the quill remains at all times attached to the shuttle body.

A further object is so to arrange and construct the parts that when the shuttle is in use the axial support for the quill will remain positively in proper position and not be likely, for instance, to become suiiiciently displaced so as to project and possibly cause damage to the goods being woven.

To this end our invention consists in providing in one of two opposed walls in a shuttle body, as in the bow thereof, a recess entering said wall from one side thereof and opening toward the other wall, together with an axial support for a quill, which support projects from the other of said walls and has its free end normally engaged in, but movable laterally of the axis of said sup port out of, said recess.

Referring to the accompanying drawing, in which the invention is fully shown, Fig- Aure l is a front elevation of the improved supporting means; Fig. 2 is a horizontal sectional viewfon line -m of Fig. l; Fig. 3 is a vertical sectional view on line g/- 1/ of Fig. l, loo-king toward the left; Fig. 4 is a similar view on line 5 2, looking toward the right; and, Fig. 5 illustrates a detail.

a designates the shuttle body, the same having the usual bow o and a wire guard c to keep they quill from engaging the shed.

d is the lquill and e the usual tension-device adapted to bear frictionally against the quill, operating as a brake thereon.

The axial support for the quill is constructed and the manner of mounting it is as follows: f is a pin or spindle, formed, say, of wire, being straight throughout, except at one end, which is turned olf substantially at right angles, as at g. This pin forms the said axial support and onto it the quill may Vbe placed, as shown in Fig. l, so as to rotate freely.

The two opposed walls la. of the shuttlebody support the pin in the usual position, z'. e., parallel with the base of the shuttlebody and are constructed for that purpose as follows: The wall 7L has an elongated recess or groove z' extending perpendicular to the base of the shuttle-body. Over this groove is secured, as by screws j, one arm of an angle-plate 7c, the other arm of which is secured in like manner against the face of the base of the shuttle-body which is within the bow. At the end of the groove which is the farther from the base the plate is formed with a hole Z. Before securing the plate in position the end g of the pin is passed through this hole, whose diameter is slightly larger than the cross-section of the pin. the plate and groove form a bearing for the part g of the pin, in which said part g fits rather snugly; the pin may then be moved in the bearing from a position in which it lies in the longitudinal axis of the shuttle, as indicated by the dot-and-dash lines in Fig. 2, to the position indicated by full lines in the same ligure. When moved onl the party as an axis the body portion of the pin will follow a plane which is perpendicular to said axis, unless pressure is applied in the direction of the length of said axis, as toward the base of the shuttle, the in being somewhat elastic so that it will yield to such pressure but return to its normal disposition when the pressure is removed.

When the plate is then secured,

Entering the wall 7L from one side thereof and open toward the wall z is a recess or groove m. The ent-rance end of this recess or groove is somewhat out of the plane in which the body portion of the pin f tends i the quill is slipped onto t-he same. The pin,

carrying the quill, is then turned on its axis g toward the position indicated by dot-anddash lines in F ig. 2 its free end being pressed toward the base of the shuttle until it enters and finally seats at the closed end of the recess m. In this position it will be held by virtue of its elasticity, unt-il, when the quill is to be removed, pressure is again applied to clear its free end from the recess.

lNe do not wish to be limited to the details of construction herein shown and described, whatwe claim being: 'The combination of a shuttle body having opposedwalls and a recess in one of said walls entering the same from one side thereof and open toward the other wall, and an elastic pin having a substantially straight body-portion and one end turned oii' at an angle to said body-portion and journaled in the other wall, whereby said pin may swing on said turned-oft end thereof as a pivot, the free end of said body-portion of the pin being engageable in said recess and the entrance end of said recess being disposed farther than the other end of said recess from the plane in which the body-portion of the pin swings when the latter is clear of the recess, substantially as described.

In testimony, that we claim the foregoing, we have hereunto set our hands, this 23rd day of November, 1909.

ADOLPH VVIDMERQ SAMUEL VVIDMER.
