MACHINE FOR APPLYING TO FABRICS ORNAMENTS INTERWOVEN WITH A BRASS 'W'IBIE.

To all whom "it may concern:

Be it known that I, HENRI MARTIN, a citizen of the French Republic, and resident of 22 Rue du Bouloi, Paris, France, have in vented certain new and useful Improvements in Machines for Applying to Fabrics Ornaments Interwoven with a Brass Wire, of which the following is a specification.

This invention relates to a machine employed for applying to textile fabrics and especially to light open-work fabrics, ornaments composed of metal wires and of textile materials such as brass wires furnished with silk pile.

This machine comprises (a) One or several series of pliers for seizing and applying the ornament. These pliers can turn around their longitudinal axes. They are placed parallel on a horizontal bar, their spacing on which can be regulated according to the spacing of the ornaments to be applied to the fabric. This bar is provided laterally with horizontal pivots around which it can move for the purpose of raising and lowering the points of the pliers so that they can take hold of the ornament and carry it into the openings in the fabric.

(b) A series of shears employed for delivering the ornament cut to the right length to the pliers. Each of the shears is placed opposite the points of each of the pliers.

(0) Two parallel rows of pins employed for tightening and slackening the fabric to be ornamented, for the purpose of assisting the pliers in placing the ornament in the meshes of the fabric. Each row of pins is placed in a separate row of meshes in the fabric and is fixed in a parallel separate ver tical bar. One of the bars is fixed and the other can turn around horizontal pivots. These two bars are borne by a horizontal rectangular frame which can move up and in' a separate parallel horizontal bar. These Specification of Letters Patent.

down.

(6) A central vertical bar placed under the stretched fabric, midway of the Width of the vertical bars in which the pins are fixed. This bar can move up and down so as to come against the fabric and serve as a point of support for the points of the pliers when they are fixing the ornament in the meshes of the fabric.

The machine and its principal parts are illustrated in the accompanying drawings.

Figures 1 and 2 are two perpendicular elevations of the shears. Figs. 3 and 4 are respectively a plan and a side elevation of the pliers for applying the ornaments to the fabric. Fig. 5 is a transverse section of the machine through the line w a: in Fig. 6. Fig. 6 is a longitudinal section through the line y y in Fig. 7. Fig. 7 is a plan of the machine taken at various levels.

The shears (Figs. 1 and 2) are composed of two juxtaposed blades 1 pivoted at 2 on a U-shaped frame 3, in the side pieces and at opposite ends of which pairs of transversely alined openings l and 5, respectively, are formed. Directly opposite the openings 5 and between the side pieces of the frame 3, is arranged a sleeve 6, the interior diameter of which is somewhat greater than that of said opening. This sleeve is provided upon its exterior with an annular rib provided at a suitable point With an outwardly projecting are individually connected to the respective blades 1 of the shears. Extending through the openings 4 and the openings 5 and sleeves 6, are a pairof shafts 9 and 10, respectively, which are for the purpose of carrying the shears horizontally. These shafts are supported laterally on the frame A of the machine by the bearin brackets 11, (see Fig. 5.) The shaft 9 is xed against rotation, while the shaft 10 on which the sleeves 6 are fixed by screws 12, is movable. For this purpose, the shaft 10 is provided with an arm 13, to which a connecting rod 14 is attached and which receives, through the medium of a lever 15, a reciprocating movement from a cam B on the driving shaft 0. On the bottom of the frame 3, opposite the points of the blades 1, tubes 16 are arranged through which the ornaments, composed of metal wires and textile ma terial are properly fed by any suitable device or means not shown. The pliers, (Figs. 3 and 4), are formed of two fiat superposed arms 17 which have a constant tendency to spring apart. These arms are tapered at their outer ends, as 18, and soldered at their opposite ends to rods 19 pivoted in bearing lugs 20 and 21 of supports consisting each, of a plate 22 provided in its bottom with a dove-tail recess. On the rods 19, adjacent the lugs 21 are arranged toothed pinions 24, which are held in position by screws 23. The plates 22 are fixed by screws 25 to a horizontal oscillating bar 26 (see Figs. 6 and 7) in suitable spaced relation. The arms 17 are encircled by rings 27 which tend to force them together. The rings of the several pliers 17 project in a pair of vertically spaced grooved bars 28, which are joined together at opposite ends and fixed to lateral slides 29 mounted in sleeves 30, fixed to the horizontal bar 26. The slides 29 are actuated by a pair of bell crank levers 31 and 32, pivoted, as at 33, to opposite ends of the bar 26. The arms 32 of said levers are attached to a rod 34 fixed to the end of a third bell crank lever 36 pivoted, at 37, to a bearing 38 of the frame A. The lever 35 is connected with the upper end of a rod 39 provided with an anti-friction roller 40, which travels in the groove of a cam C, mounted on the driving shaft 0. The horizontal oscillating bar 26 is provided atv each end with a bearing extension 41, which projects through supports 42 mounted on the frame A. The bar 26 is further provided within the frame and at one end with an arm 43, to the outer end of which is attached a connecting rod 44, the lower end of which is in turn, connected to a lever 45, which receives its oscillating motion from a cam D on the shaft 0. The several toothed pinions 24 on the plier shafts engage with the rack 46 arranged in the groove in the oscillating bar 26. This rack is reciprocated by means of the bell crank lever 47, (see Fig. 5, left hand side), actuated by the operating rod 48 provided with a roller 49 which travels in the groove of the cam E on the shaft 0.

The fabric a is spread out on a horizontal table consisting of the two spaced parts 5 and 7) mounted on the top of the frame A. It stretched horizontally between the two tables 6 b by means of two rows of pins 50 which respectively enter two parallel rows of its meshes. The pins 50 are arranged vertically in two bars 52 and 53, carried by a. horizontal rectangular frame 54. The bar 53 is fixed, while the bar 52 is provided at its bottom edge with hinges 55 about which it can swing. For this purpose, it is provided with a pendent arm 56 to the end of which a rope 57 is attached which passes over a pulley 58 carried by the tires 59 fixed to the frame A. The rope 57 is attached by means of a spiral spring 60 to the end of a lever 61 operated by a cam F mounted on the driving shaft 0. A spiral spring 62 attached to the pendent arm 56 and on the inner face of the frame 54 moves the arm into its normal vertical position. The frame can move up and down. It is provided laterally with two vertical posts 63 which slide between the horizontal ties 59 and 64 fixed to the frame A. The posts 63 are individually connected with the arms of a bell crank lever 65, and 66, pivoted at 67 on the tie 64. The levers 65 and 66, are con nected by a rod 68 so that they move in unison. The lever 66 is connected by a link 69 to a lever 70 which is operated by the cam G mounted on the shaft 0.

In two parallel rows of meshes in the fabric a, hooks 71 are mounted which are employed for intermittently moving the fabric. These two rows of hooks 71 are carried by two horizontal parallel bars 72, 73, mounted on a rectangular carriage 74 provided with four wheels 75 that run on the rails 76 of a horizontal rectangular frame 77, supported laterally by uprights 78, likewise guided in the horizontal ties 59 and 64. This frame 77 can move up and down. For this purpose, the uprights 78 are connected with the arms of bell crank levers 79 and 80, connected together by a rod 81, whereby they are actuated in unison. The lever 79 is oscillated by means of the rod 82 at tached to the end of the lever 83, which is operated by a cam H mounted on the shaft 0. The arm 72 for the hooks is fixed, while the similar arm 73 can slide on the carriage. For this purpose it is attached by means of a cable 84 provided with a spiral spring 85, to a lever 86 provided with a roller 87 that runs on the rim of a cam K mounted on the shaft 0. The carriage 74 is moved horizontally on the rails by means of a rod 88 and'a lever 89 operated by the rotation of a cam L mounted on the shaft 0.

The central arm 90 (Figs. 5, 6, 7 which acts as a pointof support for the points of the'pliers is arranged at the top of two lateral uprights 91. It is raised and lowered by bell crank levers 92 and 93 connected by a rod 94 and acting on the uprights 91. The lever 93 is oscillated by a cam M mounted on the shaft 0 by means of the lever 95 and the rod 96.

The machine acts as follows :The driving shaft 0 being rotated, the cams which it carries turn and move the various parts at the desired moment. In the upward movement of the slide 26 the pliers are opened and moved up to the level of the blades 1 of the shears and come opposite the tubes 16 through which the ornaments made of metal and pile fabrics pass. At this moment the rings 27 come near the points 18 of the pliers and close them in order that these points may take hold of the ornament. Then the closed pliers 17 begin to move down carrying along the ornament. The blades 1 of the shears then close and cut off pieces of the ornaments which remain attached to the pliers. The pliers continue to move down to the level of the fabric a stretched between the two parallel rows of pins. The points 18 of the pliers 17 carrying the ornaments then pass through the meshes of the fabric a. At the same moment the central bar 90 which has just moved up comes under the fabric a at the place where the ornaments should be fixed in the fabric. At this moment the toothed pinions 24: mounted on the plier shafts are rotated by the rack 46, whereas the pliers rotate and at first wind the ornament on the ends of their points and then proceed to fix the ornament in the meshes of the fabric a. This operation of fixing the ornament in the meshes is made possible by the mechanism whereby during the rotation of the pliers the vertical pins 50 fixed on the oscillating vertical bar 52 are inclined and come near to the vertical pins 50 fixed on the fixed bar 53 and at the same moment the horizontal frame 5 1 which supports these bars moves down. so that all the pins 50 come down under the fabric a which is no longer in a stretched state and allows the pliers 17 to wind the ornament around the mesh of the fabric a. After the pliers, in rotating above the fabric, have wound the ornament on the ends of their points and in the meshes, the rings 27 recede and the points 18 of the pliers come apart. At this moment the fabric a which is no longer supported except on the hooks 71 is moved by them so that the ornament which has just been fixed is carried along with the fabric, as the pliers are open.

While the pins 50 are lowered and removed from the meshes of the fabric a, the fabric is held by the hooks 71 carried by the bars 72, 73 resting on the movable carriage 74. As soon as the pliers are opened, the carriage is moved on the rails 76. It stretches the fabric again and carries it along in order that another part of it may come under the points of the pliers so that the pliers may deposit there another row of ornament by an identical repetition of the movements previously mentioned. As soon as the ornament is fixed in the fabric a, the central bar moves down so as not to impede the moving forward of the fabric. When this movement of the fabric is effected, the pins 50 move up again and come into two fresh parallel rows of meshes in the fabric a while the hooks 71 come near together gently in consequence of the mobility of the horizontal bar 7 8 and descend leaving the fabric 0; on the pins 50, their bars 52, 53 resuming their vertical position so as to hold the fabric stretched between the pins 50.
