In a spring system for dobbies and other weaving mechanisms of the negative type which includes hooking elements, each of the hooking elements includes, parallel to its edges which face the springs, a row of omega-sectioned openings which receive, by a lateral displacement along the axis of the opening, an endpiece of a shape to be seated within the openings.
摘要:
A device for coupling elements which are connected in line and which elements are carried by opposing holding plates wherein one of the plates is urged toward the other and threadingly locked with respect thereto by a rotating shaft having a threaded end portion which is engagable with a threaded member associated with the other plate and wherein the advancement of the threaded shaft is resiliently retarded in order to permit a proper meshing of the threaded elements upon their initial engagement.

The present invention relates to an adjustable fastener for fastening pulling cables to the suspension levers of textile dobbies of the negative type, said fastener being constituted by two parallel side elements which support a pin for the pivoting connection of the fastener to the end of the corresponding suspension lever, a curved lower guide, and an upper stop provided with two forks which are traversed by threaded end pieces fixed to the pulling cables and which form support for adjusting nuts.
摘要:
The invention relates to multiple unions of the type comprising two plates which carry elementary unions and which are brought close together or spaced apart, by force, with the aid of at least one maneuvering device of the rack and pinion type. Initial latching of the two plates is ensured by a bolt-pillar mechanism, the pinions having on the shaft an angular clearance enabling them to remain immobile and to allow unlocking when the handle begins its movement for the separation of the two plates. With this handle are associated locking means which ensure retention thereof in locked position.
摘要:
A motion damping system for a weaving machine which includes a pair of elastic members connected to supply damping force in opposite directions to an oscillating member. The oscillating member is connected to a control member so as to oscillate to and from a median position. The oppositely directed elastic members apply continous force to urge the oscillating member toward the median position.

A speed reducer of the cycloidal type for robots and other industrial manipulators including a rotating ring which receives input at rapid speed is supported within a casing by a single end bearing which forms a pivot. The opposite end of the ring abuts against roller bearings associated with a pair of cams. Actuation fingers are oriented through housings created by openings in the cams and are connected to an output. The actuation fingers are arranged to be self-centered in the housings.
摘要:
A Jacquard system for making patterns on the selvedges of fabrics being woven in a loom which includes a hollow input shaft for controlling the vertical movement of heddle support cords. The input shaft extends through a housing and a principle drive shaft extends through and is drivingly connected to the input shaft. The housing includes clamping apparatus for its adjustment along a support beam extending parallel to the principal drive shaft.
摘要:
A drawing device for actuating the heddle frames of a weaving machine of the negative type including rocking levers which guide cables extending from the heddle frame to a return spring system. The rocking levers are mounted on shafts which are shiftable within elongated slots to thereby relax tension on the cables and spring system.
摘要:
A connector for pipes including opposing body portions having bifurcated valve seats in which rotary valves are pivotally mounted by opposing pins extending from the valve seats so that the valves are automatically pivoted to an open alignment upon closure of the connector and are automatically pivoted to a closed position upon opening of the connector.
摘要:
In negative dobbies of the type incorporating swinging lever assemblies to which lever elements are connected and which lever elements support two articulated hooks, retaining members are provided in the form of pivotable locks placed between the bearing face of each hook and the pivot pins by way of which the hooks are mounted to the lever elements.
