Specification of Letters Patent.

Patented Apr. 1.1., 1.91.1.

Application filed March 26, 1908. Serial No. 423,385.

To all whom it may concern:

is recessed and flattened as shown at. ll.

Be it knownthat l, WILLIAM Wrr'rn, a The opposite side oi' the shuttle, on its inner citizen of the United Htates, residing;- at

Worcester, in the county of foreester and i State olf Massachusetts, have invented eertain new and useful lmprovements in Shuttles and Shuttle-Blocks for Narrow- VVare Looms, of which the following is a specification.

lilly invention relates to shuttles, and shuttle blocks for narrow ware looms, and the object of my invention is to provide an improved shuttle, and shuttle block ior looms of the class referred to.

lu my improved eonstruetion of a shuttle, and a sluittle bleek, I make the bearing surfaces ou the shuttle, and on the shuttle'bloek, of a material which is harder and-more durable than the rest of the shuttle or shuttle block, whieh are ordinarily made of wood. .l preferably make said bearing surfaces of ber, which-are secured to the shuttle, and

4a shuttle', .1nd o't a shuttle block, for narrow ware looms,y embodying my il'uprovements.

Referring to the tlran'ingvlfigure l a top or plan view of a shuttle embodying,r my imynovements.. Fig. 2 is an underside view ot the shuttle .shown in Fig. l. Fig. is a section, on line 3, 3, Fig. l, looking 'in the direction ol" arrow a, same figure. Fig. f-lis a rear edge view of the shuttle, looking in the direetioi'i ot arrow b, Fig. 3; a portion of thc rear part of the shuttle is broken away. Fig. 5 is a front view ot a shuttle block used in connection with the shuttle shown in the previous figures. A part of the face ot the block is broken away to show the bearinpr surface on the upper side of the groove or race. Fig. G is an edge View of the shuttle bloek shown in Fig. 5, looking in the direction ot' arrow o, same ligure. Fig. 7 is a top View of the block shown in Fig. looking in the direction ot arrow d. Fig. 8 is a section, on line 8,8, Fig. 5, lookingr in the direction of arrow same ligure.

In the aeoon'ilnlnying d rawiug, l is a shut.-

tle for a narrow ware loom, whieh shuttle i an elongated groove l, and the rear edge portion is also fiattened, as shown at 1, in Fig. $55.

A\ll of the above mentioned parts.- may be of the usual and well known construction. l will now describe my improvements.

The .surface 1 of the shuttle 1, which ordinarily forms a bearing surface of the shuttle on the shuttle block is provided with a facing or strip of material 3, as liber, which is harder than the material of which the shuttle is made, ordinarily wood, and is attaehed to the shuttle preferably by means ot hard wood pins 3. The surface 1 of theA shuttle l, which ordinarily forms a bearing` surface of the shuttle, is provided with a facing or strip of materia-l fl, as fiber, and is secured to the shuttle preferably by means of hard wood pins 4'.'

The shuttle block 5, in connection with which the shuttle l is used, may be of any -usual construction, and has the undercut 'groove or race 5 for the shuttle, 1n the usual way, 'lhe upper side of the race 5 is adapted to be engaged in this instaneeby the loe-an ingsurface B on the shuttle l, and the lower side ot the race. 5 is adapted to be engaged in this instance by the bearing surface 4 on the shuttle l. The upper Side of the'rae'e 5 is provided with a surface of harder material t), as liber, made in the form of a strip, and `secured to the shuttle block in anysuitable manner.A The lower side of the race 5 ol the shuttle block 5, is provided preferably with two strips of harder material, as 7, and 8, which form bearing surfaces for the shuttle l and are secured upon the shuttle bleek in unv suitable manner. The strip'8 forms a shelf or support for the shuttle, of harder material than the body of the shuttle block, and extends outside of the face of 'the main block, as shown in Fig. G.

The advantages of my improvements will be readily appreciated by those skilled in the art'. l provide a shuttle, having the Surface on which the moet wear comes, of harder and more durable material than thev rest of the shuttle. 1" also provide a shuttie block, having;v the surfat'es on which the most wear and friction of the shuttle come, o'l harder and more durable material than the rest. of the shuttle bleek.

ln the form of narrow ware loom t0 which my invention relates the shuttles are i Owing to gravityv and to the pressure of the pinions which engage the racks formed in the under sides of the back or heel portions 'of the shuttles the most of the Wear on the shuttles and shuttle blocks occurs at the top and bottom bearing portions of the shuttle and the top and bottom bearing portions of the grooved raceways in the shuttle blocks, and I have therefore app-lied the non-metallic facings, composed preferably of thin strips of vulcanized fiber, to the registering portions of the shuttles and shuttle blocks at which the Wear mainly Occurs. It

will thus be seen that the invention provides Such contacting rubbing surfaces as Will `resist Wear at the particular points at Which the greatest pressure, and conse- `quent greatest friction, occurs.

It will `be understood that the details of construction of my improvements may be varied if desired.

Having thus described iny invention, what I claim as new and desire to secure by Letters Patent is l. A vnon-metallic shgiittle for narrow ware'looms, combined with a shuttle block having a groove adapted to receive theV heel portion of said shuttle, one of said parts having bearing portions or facngs of harder material than its body, to resist Wear.

2. A non-metallic shuttle for narrowT Ware looms having a heel portion tted to Work in agrooved race-Way in a shuttle block, and Which heel portion is provided With a rack,` the upper and lower bearing surfaces of said heel portion/ of said shuttle having, at the points at which th'e greater friction occurs, non-metallic facings of harder Ina4 terial than the body of the shuttle, combined Witlia shuttle block, having av groove adapt ed to receive said. heel portion of said shuttle.

, vided 3. A nonmetallic shuttle fornarrow Ware looms, havin a heel portion fitted towork in a groove race-Way in a shuttle block, and which heel portion is provided with a rack, combined with a shuttle block having Va groove adapted to receive said heel portion of said shuttle, the top' and bottom" bearing portions of said block bein with facings of harder Inateris` the body of said block, to resist Wear.l

4. A. non-nietallic shuttle. for narrow Ware looms having a heel portion fitted to 'Work in a grooved 'raceway in a shuttle block and which heel portion is provided prothan 'With' a rack, the'upper and lower bearin surfaces of theV said heel ortion of sai shuttle having non-metallic facings of harder material than the body of the shuttle at the points at which the greatest friction occurs, combined With a shuttle block having a groove adapted to receive the said heel portion of said shuttle, the top and bottom bearing portions of 4said block being i provided with facings, registering with the said acings on the shuttle, of harder material than the body of said block, to resist Wear.

5. A -Wooden shuttle for narrow ware looms having a heel portion fitted to work in a groovod raceway in a shuttle block and which heel portion is provided with a rack, the upper and lower bearing surfaces of the said heel portion of said shuttle having facings of fiber Iat the 'points at Which the greatest friction occurs, combined. with a Wooden shuttle block having a adapted to receive the said heel portion of said shuttle, the top and bot-tom bearing portions of said block being provided with facings, registering with the said acings on the shuttle, of fiber, to resist wear.
