11 Claims.

This invention relates to means for converting an ordinary single-deck narrow-ware or tape loom into a partial double-deck loom, in accordance with the principles disclosed in the applicants prior Patent #1598230 dated Feb. 21, 1933. The present invention relates to improvements in the converting mechanism over that shown and described in the above noted patent.

The object of the present invention is to simplify the construction of the converting mechanism, whereby the conversion of a single-deck loom into a partial double-deck loom is greatly facilitated, by reducing the number of elements necessarily removed from the single-deck loom to be replaced by the converting elements forming the subject of the present invention, which will be fully disclosed hereinafter, reference being had to the accompanying drawings, of which:

Fig. 10 is a transverse sectional elevation taken on the line 1010, Fig. '7;

Fig. 11 is a transverse sectional elevation taken on the line 11--11, Fig. 7; and

Fig. 12 is a transverse sectional elevation taken on the line 12-12, Fig. '7.

In Figs. 1 to 6 of the accompanying drawings, the lay beam of an ordinary single-deck fiyshuttle loom is illustrated at l. 2-2 indicate the usual form of low shuttle guide brackets of a single-deck loom which are secured to the lay beam 1 by screws 3, 3. Between each adja cent pair of brackets 2 is normally located the 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 or bolts 5, 5 and 6, 6, are shuttle guide blocks '7 and 8 respectively. Each pair of guide blocks 7 and 8, secured to one of the brackets 2, constitute a raceway 9 for a shuttle 10 which carries the weft thread back and. forth across the reed comb 4 in the open shed formed by the warp threads extending through said reed comb.

In its travel across the reed comb 4, in each instance, the shuttle 10 is passed from the raceway 9 of one of the brackets 2 to the raceway 9 of the next adjacent bracket 2, reciprocation of the shuttles 10 in the present instance being efl0 fected in the same manner as described in the above mentioned prior patent.

The present invention primarily consists in substituting for any single one of the guide supporting brackets 2, or for any desired group of 76 immediately adjacent brackets 2, in predetermined places along the lay of the loom, an auxiliary bracket, or a series thereof, such as indicated at 20 in Figs. 1 to 5 inclusive.

Each of the high auxiliary double-deck 80 brackets 20 is provided with a lower securing tongue portion 21, which corresponds in general shape and character to the securing tongue 11 of each of the low singledeck brackets 2, the tongues 21 of the auxiliary brackets 20 being drilled in the same manner as the tongues 11 of the single-deck brackets 2 to receive the screws 3, 3 for securing the auxiliary bracket 20 in exactly the same position on the lay beam 1 as that as formerly occupied by the single-deck bracket 2 which has been removed and replaced by the auxiliary bracket 20.

Each of the auxiliary brackets 20 comprises a body portion 22 which is drilled and tapped in the same manner as each of the lowsingle-deck brackets 2, for receiving the screws 5 and 6 by which the guide blocks 7 and 8 of the auxiliary bracket are secured to the auxiliary bracket in the same position, with respect to the guide blocks on the low brackets 2, 2 at opposite sides respectively of the auxiliary bracket, as these guide blocks occupied when carried by the removed single-deck bracket 2.

Extending vertically from the body section 22 of the auxiliary bracket 20 is a pair of laterally spaced arms 23, 23, between which is disposed an upper deck reed comb 4a. The lower end of the reed comb 4c is seated in a cavity 25, which is formed between a cross fin 26, that extends between and is integrally connected at its opposite ends to the side arms 23, 23 respectively, and the rear face of the upper guide block 7, which is carried by the body portion 22 of the bracket 20.

The upper end of the upper deck reed comb 4a is located in a slot 25a which is formed between a back cross fin 2'7 and a front cross fin 28 integrally formed at their opposite ends with the upper ends of the side arms 23, 23 respectively.

Formed integral with and extending laterally in opposite directions from the side arms 23, 23 are upper wings 30, 30 and lower wings 31, 31.

Secured at their outer ends to the upper wings 30, 30 by screws 5a, 5a, and at their inner ends to the side arms 23, 23 of the bracket 20 by screws or bolts 51), 5b are upper shuttle guide blocks 7a, 7a, the said inner ends of which are disposed adjacent to and at opposite sides of the upper deck reed comb 4a.

Secured at their outer ends to the lower wings 31, 31 by screws 6a, 6a, are lower shuttle guide blocks 8a, 3a, the inner ends of said guide blocks being secured to the side arms 23, 23 of the bracket 20 by screws or bolts 6b, 6b.

The guide blocks Fa-8a at the opposite sides of the upper deck reed comb 4a provide raceways 9a, 9a for the reception of a shuttle 10a operable from one to the other of said guideways in the same general manner and by the same general mechanism as disclosed in the said copending application.

In the same manner as disclosed in the abovementioned prior patent the upper ends of the reed combs 4, 4 of the single lower deck are maintained in position, transversely of the lay 1, by

front and rear bars and 61 respectively, and laterally or longitudinally of the lay by and be tween pads 64, 64 formed on the opposite sides of each of the single-deck brackets 2, the bars "60 and 61 being secured to said brackets 2 by screws 62.

In the form of the invention shown in the said prior patent, in order to provide raceways for a single shuttle in the upper or auxiliary deck, it was necessary to remove three of the lower deck brackets which had to be replaced by three of the auxiliary brackets.

In the form of auxiliary bracket shown in the present application, in order toprovide the guideways or raceways for a single shuttle in the upper or auxiliary deck, it is necessary to remove but one of the lower deck brackets and to substitute one of the auxiliary brackets therefor.

The reed comb securing bars 60 and 61 are cut I away adjacent the two lower deck brackets 2, 2-

respectively disposed at opposite side of the lower deck bracket to be removed and replaced by an auxiliary bracket 20, and in order to maintain the rigidity afforded by the bars 60 and 61 the auxiliary bracket 20 is provided with laterally extending lugs 65, 65, disposed in line with the bars 60 and 61, which overlap the ends of the bar 61 at the rear of the lower deck brackets 2, 2 on either side thereof. The lugs 65, 65 are secured to the said adjacently disposed lower brackets 2, and to the bars 60 and 61, by screws 66 which pass completely through the bars 60 and 61 and the brackets 2, 2. The screws 66 are threaded into the lateral lugs 65, 65 of the auxilir ary bracket 20.

removed. However, this is not essential in that the lower wings 31, 31 may be made shorter to fit within the space between the pads 64a, 64a, making it unnecessary to remove any portion of the adjacently disposed lower brackets 2, 2.

The form of the invention illustrated in Figs. 8 to 12 inclusive concerns the application of the present invention to looms of the rack-shuttle type. In that form of the invention shown in Figs. 3 to 12, a rackshuttle loom of the type wherein the shuttles oscillate in arcuate guideways has been shown. In this type of loom a series of low brackets 102, 102 are secured to the lay 101, in the same manner as the brackets 2, 2 of the flyshuttle loom of the type disclosed in Figs. 1 to 6 inclusive, to provide a single deck in which operates a series of oscillating shuttles 110. Between each adjacently disposed pair of brackets 102 is a reed comb 104 at the opposite sides of which is a guide block 103 in which is formed a pair of intersecting arcuate T-shaped grooves forming guideways 109 for the reception of the shuttles 110. In this case the shuttles 110 are provided with segmental gear racks 140 which are arranged to be engaged by the teeth of pinions 141 rotatably mounted in cavities 142 formed in each of the guide blocks 108, which are secured to the brackets 102 respectively. The teeth of all the pinions 141 engage the teeth of a gear rack 143, which is slidably mounted in the lay 101 for reciprocation by mechanism similar to that shown and disclosed in the above mentioned application.

In order to convert this type of loom into an auxiliary decked loom, any one of the brackets 102 may be removed and replaced by an auxiliary bracket 120, in the same general manner as above described with respect to the replacement. of a bracket 2 by an auxiliary bracket 20 in the flyshuttle type of loom shown in Figs. 1 to 6 inelusive.

Each bracket 120 is provided with a tongue 121 corresponding to the tongue 111 of each of the brackets 102. The tongues 111 and 121 are correspondingly drilled to receive the screws or bolts 103 by which the brackets are secured to the lay 101.

Each auxiliary bracket 120 comprises a body portion 122 to which is secured one of the lower deck shuttle guide blocks 108, in the same position as formerly occupied when such block was carried by the removed lower bracket 101, that has been replaced by the auxiliary bracket 120.

Each auxiliary bracket 120. comprises side arms 123, 123 which are provided with laterally extending wings 130 and 131. The side arms 123, 123 are connected by lower fins 126, 126 between which is provided a cavity 125, for the reception of the lower end of the upper deck reed comb 104a. The reed comb 104d is carried by the bracket 120 between laterally spaced guide block sections 108a, 108a respectively carried by and secured to the arms 123, 123 and the wings 130 and 131 of the bracket 120. The upper end of the reed comb 104a is positioned in a slot or cavity 125a formed between a rear fin 127, which integrally connects the upper ends of the arms 123, 123 and the rear face of an upper bridge portion 128 that integrally connects the upper ends of the guide block sections 108a, 108a, and provides in the block a slot 129 in line with the reed comb 104a.

In order to oscillate the shuttle 110a in the guideways 109a formed inthe block sections 108a, 108a, a pair of gears 141a are rotatably mounted in the said blocks 108a, 108a respectively at opposite sides of the slot 129 for engagement with the rack teeth in the lower surface of the shuttle 110a. The gears 141a, l ila mesh with the teeth of an upper deck rack 143a which moves in unison with the lower rack 143 and which may be connected to the rack 143 in any suitable manner to be reciprocated with the rack 143 by the same mechanism which reciprocates the said rack 143. The rack 1 13a is slidably mounted in grooves 114 formed in the upper ends of the guide blocks 108 carried by the lower brackets 102 respectively.

From the above, it will be noted that the present invention is applicable to the conversion of single-deck looms of either the fly-shuttle type, such as that shown in Figs. 1 to 6, or the racktype loom shown in Figs. '7 to 12, with equal facility in either case, by merely removing one of the lower deck brackets and replacing such bracket with one of the interchangeable auxiliary brackets.

It will be noted that the lower wings 31, 31 in that form of high bracket shown in Figs. 1 to 6 inclusive include cavities 25b, 25b for the reception of the upper ends of the reed combs 4, 4 of the lower deck which are respectively disposed between the high bracket and the two low brackets respectively disposed at opposite sides of said high bracket.
