SHUTTLE GUIDE FOR LOOMS Filed Nov. 27, 1926 2 Sheets-Sheet 2 Patented June 17, 1930 onira earns rarest JAMESE. HARDING, OF BRUNSWICK, NEXV JERSEY, ASSIGNOR T GULBENKIAN SEAMLESS RUG COMPANY, OF NEW BE J'NSVJICK, NEW JERSEY, A CORPGRATION OE N EW JERSEY SHUTTLE GUIDE FOR LOOIVIS Application filed November 27, 1926. Serial No. 151,147.

/ My invention relates to looms which employ an oscillating lay having a shuttle box on either end of said lay and a shuttle adapted to be reciprocated across the lay from box to box, through the open warp shed of the fabric being woven on the loom.

The principal object of my invention is to prevent the shuttle from being. deflected from its course as it leaves the open warp shod, as by such deflection it does not enter the shuttle box but is projected at a terrific velocity clear of the loom, causing both property damage and personal injury to operators, as is well known to textile manufacturers. I

To permit variation in the widthof fabrics woven on a loom, the distance intermediate the slnittle boxes is maximum, and when a fabric of lesser width is being woven so a space between the longitudinal edges of the body of warp threads and the adjacent end of the shuttle box exists, being sufficient to permit the shuttle to be deflected, before it enters the mouth of the box, by the resiliency of the warp threads of thelower level of the open. shed. By the use of my invention a guide is provided between the end of the box and the edge of the body of warp threads, thus preventing the saiddefiection of the Shuttle, by guiding it from the open warp shed into the mouth of the shuttle box.

The details of my invention will be fully disclosed hereinafter, reference being had to the accompanying drawings, of which:

Fig. 1 is a plan View of sufficient of the elements of a loom to illustrate my invention;

Fig. 2 is an end elevation;

Fig. 3 is a sectional elevation taken on the 4 line 8-3 of Fig. 1; and

Figs. 4- and 5 are detached perspectiveviews of details of my invention. I In the drawing, the 100111 side frames are illustrated at 1, 1 being connected by a cross member 2. The oscillating lay is illustrated at 8, and comprises arms 4, 4 pivoted to the frame members 1, 1 at 6-6, and connected by a lay beam 7 at their upper ends. A shuttle beam or race 8 is also secured to the arms 4, 4: in the usual manner, and is provided under which the shuttle 93 passes.

with a shuttle box 9 of usual construction,

at each end, comprising a rear wall 10, a

front wall 11 and a top wall 12, the race 8 the bottom or floor of the shuttle 18, for minimizing-the wear and jar on the shuttle. The shoe 18 is provided with a vertically extending 1 supporting leg 22 adaptedto be secured to the lay beam 7 by means of a bolt 23 andoscillateswith the lay 3.

The right guide 17 is formed similar to the guide 16, but does not oscillate with the lay, being provided with a horizontally extending leg 22 which is securedby' bolts 24:, 24 toa fixed portion of the loom frame, in the'presentinstance the harness guide 25. The guide 17 does not oscillate with the lay 7 for the reason that when the lay is in the forward or beat-up position, the guide 17 would strike against the heads of the pile wires (not shown) and for this reason the guide 17 is stationary, occupyin a position immediately adjacent the plane or movement of the inside surface of thevright arm 4;, under the lay beam 7. The guide 17 is in correct position to guide the shuttle when ed to said frame comprising lay arms, a lay beam and a shuttle. race, and having shuttle boxes on said shuttle race; a shuttle guide adjacent the mouth of each shuttle box, a supporting leg on each guide, one of said legs being securedto said lay and the other leg being secured to the 100111 frame.
