ELECTRICAL JACQUARD MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 727,023, dated May5, 1903.

Application filed $eptember 24, 1900. Serial No. 30,990- (No model.)

To all whom/it may concern:

Be it known that 1, JAN SZOZEPANIK, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary,

have invented certain new and useful Improvements in Electrical J acquard Mechanism for Looms and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved arrangement of the electromagnets in electrical jacquards which enables the magnet to be easily changed without considering the con nections, and consequently enables the connections of the electromagnet 'to be easily altered. The electromagnets are arranged in' such a way that in consequence of the formation of a ring of lines of force one armature cannot influence the adjacent armatures.

Figure l of the accompanying drawings shows, by way of example, the complete ar-' rangement of the electromagnets in an electrical jacquard the electromagnets of which 0 control the movement of the needle as determined by an electrical templet. Fig. 2 is a horizontal section of the magnet-box. Fig. 3 shows one of the electromagnets in longitudinal section.

The electromagnets Ct,Wl1lCh act in the usual manner on the armatures d, that control the needle b of the jacquard c, and release them when influenced by the magnets-,are arranged in holes in an electrically-conducting magnet- 40 boxf and bear with their outer ends on contact-buttons g, which are pressed by springs h against the ends of the electromagnets. The pins 2', carrying these buttons 9, pass through a contact-boardj and are connected,

5 by means of clamped conducting-wires lc,with pins m, arranged in a second contact-board l and provided in a similar manner with spring contact-buttons a. Each of the contact-buttons n is spring-pressed against a projection 0 of its respective stationary conducting bell-crank lever 0 of the selecting device 19, the movable members 00f which. rest on the movable templet q. There is one finger 0 connected to its corresponding be1lcrank lever 0, each of the latter having a single projection 0 contacting with its respective button 17.. The fingers 0 are thin conductor-plates having at their hinge end a circular cut-away portion that is more than a half-circle. This recess fits over the boss 20 of the upturned lower ends of the conducting-levers 0. These upturned ends are circular, from which segments have been cut on each side of the center to form parallel chords. When the free ends of the fingers 0 are lifted to a sufficient extent, they can be slid into position on the circular portions 20 and as sume the position indicated in Fig. 1, their ends resting on the templets g. This templet comprises, as usual, a metal plate which con- 7o ducts-at portions left bare, but does not conduct at other places which are covered with an insulating material. Underneath the templet there is arranged the current-supplying lever r, which is in contact with it and is connected to the current-supply wire .9, while the return-wire t is connected with a terminal It on the magnet-box.

When a contact-lever 0 touches a bare or conducting place on the templet, the circuit is closed and the current flows from 3 through 1" to the templet q,through the corresponding contact-lever 0 and the corresponding contact-button n and wire it to the second corresponding contact button g, and then through the corresponding electromagnet a to the magnet-box f, thence to the terminal at, and back to t. The electromagnets are thus selectively energized. The grid d, that moves the armatures d, one in each opening 61 for each magnet 00, is vertically movable between the needle-board b and the magnetbox, so that said armatures will be moved into alinement with their respective magnets.

When so moved, the energized magnets (all 5 of those shown in Fig. l are supposed to be energized) will attract the armatures and hold them. The grid d is then moved down or dropped into the position shown in Fig. 1,

the openings in the grid being larger than too the magnets, so that each armature that has been alined with its respective energized magnet will be held thereby to cover the opening in the needle-board b and prevent the needle from being moved in, thereby holding the respective hooks out of engagement with their griifs. The needles I) are normally held retracted, and after the armat'u res have been selectively held in place those so held act as distance-pieces, so that when the needles I) are moved toward the magnets a those needles opposite the spaces not occupied or filled by armatures will enter them.

By means of the arrangement described the connections of the electromagnets can be easily altered, since the contact-boards can be removed and others substituted therefor. Furthermore, a machine with ,a large number of lifting-wires can work a machine with a small number, if all of the electromagnets operating the superfluous needles are cut out by removing their contacts.

In order to permit of the described course of the current and to prevent an excited magnet from influencing the adjacent magnets, the magnets are made as tubulated magnets of special construction. Fig. 3 shows such a tubulated magnet on a larger scale.

The conducting magnet-core 1 is surrounded by the winding 2 and is inclosed in a conducting tubular casing 3, which is firmly connected to the core by means of a screw 4:.

The annular space for the winding 2 between the core and the casing is closed at one end by the enlarged end of the core and at the other by a ring 5. I

To the enlarged end of the core there is secured, by means of a screw 7, that passes through an insulating-sleeve 6, a hoilowedoutcontact-button 8, which is completely insulated from the core by means of a disk 9, made of non-conducting material. Between the contact-button 8 and the insulating-disk 9 one end of the winding is clamped, while the other end of the winding is soldered or otherwise connected to the core at 10. The current fiows,therefore, from the spring contact-button g of the boardj to the contactbutton 8 of the electromagnet, thence to the core through the winding 2, that surrounds it and excites it, and from the core through the casing 3 to the magnet-box f, in order to return in the manner hereinbefore described from the magnet-box to the return-wire t.
