UNrrEo STATES gturriszu'r ortica ANDREW' VJ'EIMAR, OF PHILADELPHIA,

PENNSYLVANIA, ASSIGNRy TO WEIMAR BROTHERS, OF PHILADELPHIA, PENNSYLVANIA, A :FIRE/I CONSISTING OF ANDREW WEIMAB AND VILLIAI'I D. WEMAR TAPE nocivi Application e May 3,

This invention relates to means for converting` an ordinary single deck fly-shuttle narrow-ware or tape loom, which 'usually has from forty to sixty strips oftape' undergoing manufacture at one time, into what may be termed a partial doubledeck loom.

Single deck looms are well known and complete double deck looms'are well known. Double deck looms, however, have not been successful for various reasons including the diiicultv encountered in getting skilled operators to operate them. Another disadvantage of full double deck looms resides in the added weight of the double deck which requires that the speed of such looms be greatly reduced from that of a single deck loom, for example, to 150 beat-ups a minute, whereas single deck looms are ordinarilyoperated at about 200 beat-ups a minute.

l have found that byv applying auxiliary decl-:s at spaced intervals along the lay'of an ordinary single deck loom the normal speed or 20() beat-ups per minute maybe maintained and that no dilliculty is experienced in obtaining sl-:illedoperators to work such machines, for the reason that instead of havto reach overthe top of the upper deck in tying up broken warp ends, etc.,as in the furl double deck loom the operators can readily reach around the sides of the auxiliary decks for the same purposes.

Other advantages ci operation and construction will be fully disclosed hereinafter, reference being had to the accompanying drawings, o1" which:

Figs. l and la constitute a face view of the lay of a loom made inaccordance with the principles of'my invention;

Figs. S and 9 are perspective views of one ol the shuttle operating fingers; and

F ig. l is a detail section taken onthe line l0, l0, Fig. 2.

ln the accompanying drawings, the lay beam of an ordinary single-deck loom is illustrated at l. 2, 2 indicate the usual form of shuttle guide brackets which are secured to the lay beam l by screws 3, 3. In an ordinary sixty strip single-deck loom there would be sixty-one of these brackets 2 and between each 'adjacent pair of brackets 2 is normally located a reed comb 4, through which the warp ends of the strips of tape extend.

Secured to each of the brackets 2 by means of screws 5. and G, 6 are guide blocks 7 and 8 respectively. Each pair of guide blocks 'I' and 8 constitute a raceway 9 for a shuttle l0 which carries the weft thread back and forth across the reed comb 4 in the open shed formed by the warp threads extending therethrough.' f

In its travel, the shuttle l() is passed from the raceway 9 of Vone bracket 2 to the raceway 9 of the next adjacent bracket 2,-the shuttle being engaged by a finger ll, such as shown in'gFig. 8, which is secured to and projects verticallyfrom an operating bar 12 longitudinally slida'bly mounted in a groove 13 *formed in the lay beam l.

The 'actuating bar l2 receives longitudinal reciprocatory movement, whereby the lingers ll are moved from the position shown in Fig. 2 of the drawing at the right handend of each guideway 9 to the left hand end of the said guideway whichthrows the shuttle from the guideway 9 of one bracketf2 into the guideway 9 ofthe next Vbracket, across the intervening space between the ends of the relatively spaced guideways 9,-9 and infront of the reed comb Ll. Reverse movement of the bar l2 moves the shuttles l0 in the corresponding reverse direction.

The present invention consists primarilyk in substituting :for some of the usual guide supporting brackets 2 at predetermined places yalong the lay of the loom, auxiliary brackets, such as indicated at 20, 20, and as shown in Fig. 6, each bracket 2O having a lower tongue portion 21corresponding to v the lower tongue portion 22 of rthe ordinary brackets 2. The tongue 21 of the brackets 2() are drilled in the same manner as the tongue portions 22 of the ordinary brackets 2, so as to be interchangeable therewith, and adapted to receive the ordinary securing screws 3 in the same general manner as the brackets 2.

The body portions of the brackets 20 are adapted to receive the lower deck guide blocks 7 and 8 in the same general manner as the brackets 2 and in addition thereto the brackets 20 are provided with upwardly extending arms 23, 23, between which, in each bracket 20, is provided an upper reed comb 4a.

Secured to the right side arm 23 of one bracket 20 and to the left side arm of the next adjacent bracket 20 are guide blocks 7 a and 8a between which are formed the upper raceways 9a for the upper shuttles 10a.

Certain of the shuttle-operating fingers 11 are replaced bv fingers 111 which are adapted to receive, support and operate an upper finger-operating bar 12a on which is provided shuttle-operating fingers 11a for operating the upper-deck shuttles 10a.

rlhe principal obfect of this invention is to arrange the auxiliary decks at spaced intervals alo-ng the loom. Each auxiliary deck to accommodate about four shuttles, providing sufcient space, equal to about four shuttles or more, between the auxiliary upperdecks so that the operators may readily reach in between the auxiliary decks to make necessary repairs or adjustments at the back of the lay.

Should it be necessary or desirable at any time to' change the loom back to a. single-deck machine for some classes of' work, the brackets 2O may, by virtue of their interchangeability with the lower brackets 2, be readily removed and the usual low brackets 2 reinserted in place thereof, which is impossible with the ordinary double-deck loom.

The shuttle-operating fingers 111 are likewise made in a manner capable of interchangeability with the fingers 11 in the operating bar 12 so that an upper operating bar 12a of any desired length may be applied at any point desired, to accommodate any desired number of upper shuttle-operating fingers 11a.

Herein lies another feature of the present invention, i. e. all the shuttles o-f both the regular lower-deck and those ofthe upper auxiliary decks are actuated from and by the one single actuating bar 12 which in turn is actuated by a. single operating mechanism 30 located at one end of the lay 1. This operating mechanism is of the usual construction, comprising a vertical slotted bracket 31 in which operates a block 32.

In the block 32 is rotatably `mounted a crank pin 33 which is secured to a crank arm 34. The crank arm 34 is secured to the end of a shaft 35 which is rotatably mounted in a bearing 36 carried by the lay 1. The shaft 35 is provided with a pulley or sprocket wheel 37 around which passes a belt or drive chain 38. The operating element 3S is connected to a suitable rocking mechanism (not shown) which effects rocking of the shaft and a consequent reciprocation of the shuttie-'actuating bar 12.

In order to prevent excessive wear of the bar 12 and the walls of the slot- 13 in which it is slidably mounted, as could be caused by the tendency of the bar 12 to fall frontwardly by the oscillation of the lay 1, 1 provide fixed brackets 40 on the lay 1, and each bracket comprises a rail 41 against which a roller 42 operates, each roller or shoe 42 being carried by a` standard 43 which is rigidly secured to the shuttle-actuating bar 12.

As shown in Figs. 8 and 9, the fingers 11 and 111 respectively are provided with rectangular shanks 45 which snugly fit the same correspondingly shaped apertures 46 in the shuttle-actuating bar 12. If desired, these shanks and receiving apertures may be of a tapering nature to more securely cause the shanks to tightly fit the openings.

The reed combs 4, as above noted, ordinarily occupy positions between each adjacent pair of low brackets 2, each comb being provided with a lower head 50 and an upper head 51.

The lower head 50 fits in a groove 52 formed in the back upper edge of the lay 1, the ends 53, 53 of the head 50 abutting pads 54, 54 formed on the sides of the brackets 2, to keep the combs in proper position longitudinally of the lay 1. The heads 50 are held in the groove 52 by a longitudinally extending bar 55 secured to the back of the lay 1 by screws 56.

The upper heads 51 of the lower-deck reed combs 4 ordinarily are disposed between parallel bars 60 and 61, see Fig. 10, secured to the front and back faces of the brackets 2, by screws 62, and extending longitudinally of the lay 1, the ends 63 of the upper heads 51 abutting pads 64 formed on the opposite sides of said brackets 2.

Each bracket 20 intermediate its side edges 24, 24 is of equal width to the corresponding measurement of each bracket 2 intermediate the outer surfaces of the oppositely disposed pads 54, 54 and 64, 64 respectively, so that when any of the brackets 2 are replaced by brackets 20 the reed comb cavities 25 between brackets will be alike.

Vhen such replacement takes place the reed comb retaining bars 60 and 61 are cut in the manner shown in Fig. 2, the front bars 61 stopping at the inner edge 24a of the outermost arm 23 of the inserted bracket 20 and the end of the bar being secured to the arm of the bracket by a screw 6b which is threaded into the opening in the arm which has been provided for the screws 6a which secured the lower elements 8a of the upper shuttle guide 9a to the brackets 20, it being noted that the said elements 8a, 8a are in alignment with the retaining bars 60, 6l, longitudinally of the lay l of the loom. The back bar 60 stops adjacent the outermost edge 24 of the bracket 20. The upper heads l of the lower reed combs d which are disposed between adjacently positioned high brackets are held in their' cavities 25 against longitudinal movement relative to the lay l between opposed side edges 24, 24 of the brackets 20 and against lateral movement relative to the lay at their backs by lugs '70, 70, which project in opposite directions from the opposite side edges 24, 24e of each bracket 20.

Each bracket 20 is provided with a cavity 25a for the reception of the upper reed combs la of the auxiliary decks. Eachcavity 25a is formed between the inner opposed edges 24a, 24a of the arms 23, 28 of the bracket 20. Extending across the bracket at the back thereof is a rib 75 between which and the back face of the upper element 7 of the lower shuttle guideway 9, the lower head a of the upper reed comb la rests. A bottom rib 76, which also extends between the arms 23,

23, holds the reed comb la against downward vertical movement, see Fig. 4:.

The upper head 5l of the upper reed comb fla is held against lateral movement, relative to the lay l, between a rib o, extending between the arms 23, 23, and a front bar 7l secured to the front faces of the arms 23, 23 by screws 72.

In order to give the machine when equipped with the auxiliary decks a ship-shape appearance and to provide a maximum amount of space between auxiliary decks I remove the upper portions of the4 outermost arms 23 at the extreme ends of each auxiliary deck, as indicated at 23a, 23a in F ig. 2, as there is no use for these particular portions at that time.

F rom the above,-it will be obvious that by merely providing a set of special shuttle guide supporting brackets which are interchangeable with the ordinary low shuttle guide supporting brackets of an ordinary single-deck tape loom, and by providing a set of special interchangeable shuttle operating lingers, I can readily convert an ordinary single-deck loom into a partial or full double-deck loom, but for the reasons noted in the preamble of this specication I prefer to provide merely auxiliary decks at spaced intervals along the lay cf the looi I claim:
