JACQUARD CARD-WIRE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed April 3. 1907- Serial No. 366,904.

. a part'of this specification.

My invention relates to devices, known as card wires, employed to support on races the cards of a jacquard or other similar machine in the interims between their passing over the cylinder of the machine.

The object of the invention is to provide a card Wire which, while possessing in itself means for securing it against endwise play when operatively attached to a series of cards, will be comparatively little more, if any more, expense to manufacture than the .plain straight card wire now in common use,

secure against becoming detached from the cards, and capable of being applied to the cards so that either side thereof may be presented to the cylinder.

The invention will be found fully illustrated in the accompanying drawings, where- 1n,

Figure 1 shows several cards laced together and one of the improved card wires attached thereto; Fig. 2 is a perspective view of the card wire showing the manner in which it engages the lacing; Fig. 3 is a view illustrating the card wire as it rests on the cylinder, the lacing being shown in section; and, Figs. 4 and 5 are a plan view and a side view, respectively, of the card wire.

In the drawings, a designates the cards, I) the cylinder having the pegs c which engage with the holes (Z in the cards to cause the advancement of the series of cards, and e the usual lacing between the cards.

f designates the improved cardwire. This is preferably a plain piece of wire having its end portions bent so as to form hooks or crotches g opening toward each other for the reception of the lacing and projections 71. extending beyond said hooks so as to serve to support the wire on the race (not shown). Said hooks or crotches and projections are produced as follows: The end portions '1'. of

the wire are bent first back on themselves in the same plane and parallel with the bodyportion is of the wire in such manner as to leave narrow spaces Z, each space being accessible only from the inside, i. a, from the direction of the further end of the wire. Said end-portions are then again rebent, preferably both in the same direction with respect to the body portion of the wire, this time outwardly and in a plane at right angles to the plane occupied by said body-portion and the first rebend. The bending of the wire is-so accomplished that the extremities thereof project, after the second bending, beyond the hooks or crotches 9 so as to form the projections h. The second rebends are shown in the drawings as formed so that no spaces are left, such as the spaces Z; though this is not absolutely essential.

In assembling the wires and the laced cards, one hook of each wire is slipped over the lacing between cards and then the two cards are bent somewhat, transversely, until the lacings are brought closely together enough so that the other lacing may be in like manner entered into the other hook. The hooks should be spaced apart sufliciently so that the two lacings will abut nicely against the hooks when entered therein and thus keep the wire against endwise movement. When thus assembled with the cards the wires stand in such position with relation thereto that the cards are opposite the spaces Z formed by the hooks and, owing to the fact that each wire is bent in the peculiar manner above described, its body-portion and the projections h Will be in planes on opposite sides of the plane occupied by the cards and lacings and equidistant from said plane. The advantage of this feature is that the wires may be used indifferently either side up, i. a, the body-portions above and the projections below the lacings, or vice versa, and whether they are in the one position or the other the lacings come the same distance from the face of the cylinder as the wires are passing over the latter and the cards engage the pegs on the cylinder at the same elevation. If the projections were arranged in a plane which was further from that of the lacings than the plane of the bodyportions of the wires, the wires could not be used.either side up without either making the pegs unduly long or having to contend with the cards more or less frequently slipping over the pegs.

'said hook, substantially as described.

2. A jacquard card-wire having a substantially straight body portion and its endportions rebent first toward each other and forming open hooks and then rebent away from each other, the extremities of the wire s'i'aeio being projected beyond the hooks to form the supporting portions of the wire, substantially as described.

3. A jacquard card-wire having a substan tially straight body-portion and its end-portions rebent first toward each other and forming open hooks and then rebent away from each other, the two rebends being disposed in planes intersecting each other, substantially as described.

In testimony, that I claim the foregoing, I have hereunto set my hand this 5th day of April, 1907.
