Abstract: 152,010. Martens, F. A. Oct. 6, 1919, [Convention date]. Warp threads, uniting. - Warps are joined mechanically by drop-like quantities of glue, and the joints are immediately dried by passing them over a heated roller and under a current of air, preferably heated. Figs. 3 and 4 show part of the mechanism, which comprises, on a shaft 70, a thread-separating device 63 called a " heart," resembling in form a stunted pyramid; this device, which, according to the Specification as accepted, is arranged in the manner described in Specification 24749/12, is mounted between lease-rails 53, to each of which are fitted glue-receptacles 64 supplying glue for connecting the warps, a heated roller 5 and an air-supply fitting 72, 65 for drying the joints, and a toothed wheel 15 for moving the connected warps laterally on to the drying-roller 5. The warps 61, 57 in the loom, and the warps 62, 58 to be connected to them, are stretched between the rails 53, and the shaft 70 carrying the " heart " 63 is reciprocated between the rails so as to separate from the warps the two threads next to be joined. The " heart " 63, near the end of each reciprocation, strikes a lever 19, Fig. 8, pivoted at 21; the shorter arm 20 of this lever has a pin engaging with a slot 41 in an arm on a rod 8, which is thus moved horizontally against the pressure of a spring 23. The " heart " a also strikes the end 34 of a spring lever 32, which is pivoted at 31 and normally rests against a stop 33; the lever 32 causes an arm 30, Fig. 7, to oscillate, so that the pawl 26, engaging with the rack 75, causes the pasting-device to move bodily along the framework 2, and across the warps. The movement of the rod 8 effects the oscillation of an arm 13, which is controlled by a stop 14, and operates an air pump supplying air to the gluecontainer 4 and thus causing the exudation of the glue from the apertures 67. The spring-supported pawl 9 on the rod 8 effects the rotation of the " gripping " wheel 15, and also of the heater 5 on the same spindle 6. During these movements the movement of the " heart " 63 causes the rollers 68, Fig. 4, to engage alternately the sides of the framework, and the arms 66 to disengage from the unconnected warps the two threads next to be joined, and to deliver them to the wheel 15, Figs. 3 and 7, at the point 3, Fig. 7, where they are secured by a spring 42. When the " heart " 63 moves back towards its central position, the rod 8 is moved back by the spring 23, and the wheel 15 and the beater 5 are rotated, so that the gluedtogether threads are delivered to the heater 5, where the joint is dried. Simultaneously the mechanism opens an air cock and air is supplied by the jet 65, Fig. 3, to complete the drying of the joint. To prevent the wheel 15 from carrying down and cutting the connected warps, a " wing " 39, Fig. 10, is actuated by levers 36, 37 and a counter weight 38 so as to remove them from the wheel 15. The warps are stretched between rollers beyond the lease-rails 53, and are spaced by a comb. The air-supply device is moved along with the glueing-device by the " heart " 63 striking an arm 73 on the air conduit 72. The heater 5, Fig. 8, is electrically heated by current supplied through brushes 11, and rollers 10. It is cleaned by a scraper 12.
