Patented June 5, 1973 2 Sheets-Sheet 2 INVENTOR. Mr/ fiawrmjw- HARNESS CONNECTOR FOR JACQUARD MACHINES The present invention relates to a harness connector of synthetic material for Jacquard machines, which harness connector is made of one piece and has a loop on one end thereof which may be bent apart for attaching harness ties. Such harness connector represents a connecting link between a hook or lifter of a Jacquard machine and the harness cords of a loom. When the said loop is closed, said one end rests in a support provided on the base of the loop and operative in the longitudinal direction of the harness connector.
Synthetic harness connectors of the above mentioned type are known, in which a thickening of the shaft forms the base of the loop, in which is provided a cutout for a hammer head shaped loop end. Following insertion of the hammer head shaped loop end, the base of the loop is supposed to form a support, operative in the longitudinal direction of the harness connector, for the hammer head end of the harness connector, which is under the pulling action of the harness cords. These known harness connectors have the drawback that they open much too easily during operation of the Jacquard machine. This occurs because the harness connectors are not always under a uniform pulling action of the harness cords. Rather during the stopping of the hook or lifter bars on which the harness connectors are suspended in their uppermost position and during the lowering of the bars from this position, the harness connectors are briefly partially or entirely released from the pulling action by the harness cords. Opened harness connectors immediately cause faulty shed formation and thereby flaws in the weaving.
It is an object of the present invention to produce a synthetic harness connector of the above mentioned general type, in which the connection between the end of the loop and the base of the loop, after the loop is hooked in, holds together with absolute reliability, while simultaneously retaining the advantage of a releasable connection.
It is a further object of the invention to eliminate the disadvantages of the state of the art.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings in which:
FIG. 1 shows a harness connector with an opened loop according to the invention.
FIG. 2 shows the same harness connector as FIG. 1 but turned by 90 and in closed position.
FIG. 3 is a section taken along the line III III of FIG. 1.
FIG. 4 is a section taken along the line IV IV of FIG. 1.
FIG. 5 is a section taken along the line V V of FIG. 2.
FIG-6 illustrates a different embodiment of the harness connector according to the invention with an opened loop.
FIG. 7 shows the same harness connector as FIG. 6 but turned relative thereto by 90 and in a closed position.
FIG. 8 is a section taken along the line VIII VIII of FIG. 6.
FIG. 9 is a section taken along the line IX IX of FIG. 6.
FIG. 10 is a section taken along the line X X of FIG. 7.
Starting with a known synthetic harness connector, which consists of one piece and has a loop on one end thereof which may be bent apart for suspending harness cords therein and in which said one end, when the loop is closed, rests in a support provided on the base of the loop and effective in the longitudinal direction of the harness connector, the present invention is characterized primarily in that the support on the base of the loop comprises a collar-like reinforcement while the end of the coop comprises a conical shoulder or extension with a longitudinally extending slot which overlaps the reinforcement and embraces and partially catches behind the shank of the harness connector.
According to one practical embodiment of the harness connector according to the invention, the collarlike reinforcement, on that side of the base of the loop which faces towards the shoulder, may have a recess for receiving the shank of the end of the loop. In addition thereto, a web may be provided above the collarlike reinforcement on that side of the base of the loop which faces away from the shoulder, which web lies in the slot of the conical shoulder on the end of the loop when said loop is closed.
In a preferred embodiment of the invention, the recess is arranged opposite the web and embraces the shank of the loop, so that the latter is doubly secured against unintentionally springing open.
According to a further refinement of the invention, the harness connector is formed in such a way that, when the end of the loop is open and relaxed, it rests in a plane of the shank of the harness connector which is parallel to the longitudinal axis of the shank.
The harness connector formed according to the invention has the advantage of an absolutely reliable snap connection between the end of the loop and the shank of the harness connector, while simultaneously retaining the advantage of a releasable connection.
Referring now to the drawings in detail, the harness connector 1 shown in FIGS. 1-5 comprises a one piece formed part of a suitable synthetic material. The upper end of the harness connector is provided with an eye 2 for suspending therein a lifter or hook (not shown) of a Jacquard machine. The lower end of a shank 3 has a collar-like reinforcement 4, which serves as a support or counter bearing for a conical extension 5 located at the end of a loop 8 formed of arms 6, 7. On one side, the conical extension 5 is provided with a slotted cutout 9, which is adapted to embrace and partially to catch behind the shank 3. A recess 10 (FIG. 3) is provided in the reinforcement 4 for the arm 7 of the loop 8. Above the reinforcement 41 a web 1 1 extends along one side, which web will be located in the slot 12 of the extension 5 when the loop 8 is closed.
In the harness connector la shown in FIGS. 6l0, the recess 10a provided in the reinforcement 4a is arranged opposite the web Ila and is grooved so as to be able to catch behind the shank 7a of the loop 8a.
As will be seen from the above, the harness connector according to the invention has the advantage of an absolutely reliable snap connection between loop end and the shank of the harness connector while at the same time the advantage of a disengageable connection is retained.
It is, of course, to be understood that the present invention is by no means limited to the specific showing polypropylene.
