LOOM FoR CROSS-HWEAVING.

srEoIrIcA'rroN forming part of Letters Patent No. 642,361, dated d'anuary so, iooo.

Application filed August 24, 1899.

To all whom, it may concern:

Beit known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Looms for Cross- Weaving, of which the following is a specifi- My invention relates to certain improvements in the construction, arrangement, and mode of operation of the several parts of a loom for cross-weaving whereby the loom will be capable of weaving a number of different patterns by a very simple manipulation of the heddles, the structure comprising a main heddle and a plurality of auxiliary heddles arranged one above the other in proximity to the main heddle, the said auxiliary heddles comprising bars or plates extending transversely across the loom, the said bars or plates being provided with eyes through which the auxiliary warp-threads are caused to pass. Simultaneous vertical reciprocating movements are imparted to the auxiliary heddles, the said auxiliary heddles being adapted to be reciprocated laterally independently of each other.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a vertical section taken from front to rear through a loom embodying my invention. Fig. 2 is a transverse vertical section taken in the plane of the line 2 2 of Fig. 1, portions of the loom being broken away to bring the side frames of the loom closer together. Fig. 3 is a partial transverse vertical section taken in the plane of the line 3 3 of Fig. 1, and Fig. 4 is a detail view showing the heddles and their adjacent parts in the reverse position to that shown in Fig. 1.

I have set forth certain features of construction for the clear understanding of my present invention which are not claimed herein, as they form part of the subject-matter of two pending applications filed by me on the 25th day of May, 1899, and the 31st day of May, 1899, their serial numbers being 718,221 and 718,926, respectively.

The side frames of the loom are denoted by A, and mounted therein in suitable bearings Serial No- 728,3Z9. (N0 model.)

is the slay-beam-operating shaft B and the cam-carrying shaft C. The slay-beam-connecting rods I) lead from the shaft B to the slay-beam, as is usual, for imparting the rocking movements to the slay-beam. The warpsupplyingroll is denoted by E, and itis mounted, as usual, at the back of the loom between the side frames A. The shafts B and Care driven by any suitable mechanism. (Not shown herein.)

The weft-supplying mechanism has been entirely omitted in the accompanying drawings, as it is thought unnecessary to the clear understanding of my invention,which relates particularly to the warp mechanism.

The main heddle is denoted by F, and it is guided in its upward and downward movements by means of suitable sleeves ff at its sides,which surround a pair of vertical guiderods G G", which are mounted in suitable lower and upper bearings g 9, so as to rock in the said bearings.

The main heddle F is provided with alternating reeds and needles, the reeds extending between the upper cross-barf and the lower crossbar f of the heddles and the needles projecting downwardly from the upper cross-barf to a point about halfway between the two cross-bars, the heads of the said needles being provided with suitable eyes for the passage therethrough of the main-heddle warp-threads.

The auxiliary heddles are denoted by H and I, and they are located at the back of the main heddle F in close proximity thereto. The lower auxiliary heddle I comprises a cross-beam 'i, upon the top of which is secured in any suitable manner a cross bar or plate 1', the forward end of which is turned upwardly, as shown, through which upturned portion I provide a plurality of eyes a? for the passage therethrough of the lower auxiliary-heddle warp-threads.

The upper auxiliary heddle H comprises a.

cross bar or plate It, spaced from and supported above the lower auxiliary heddle I.

The forward edge of the auxiliary heddle H is turned upwardly, and through such upturned portion I provide a plurality of eyes h for the passage therethrough of the upper auxiliary warp-threads. The upper auxiliary IOO heddle H is supported at points intermediate its ends by suitable webs 2' uprising from the plate 2'.

The upper and lower auxiliary heddles are reciprocated laterally independent of each other in the following manner: The lower auxiliary heddle I is secured at one end, in the present instance at the right-hand side of the loom, to a carriage K, as shown at i which carriage has a free vertically-sliding movement along a supplemental guide-rod J, which is carried in the free ends of a pair of rearwardly-extended arms j fixed to rock with the vertical guide-rod G.

One end of the upper auxiliary heddle'H,

in the present instance the end at the lefthand side of theloom, is secured to a carriage K, as shown at 7L2, which carriage has a free vertically-sliding movement along a supplemental guide-rod J, which is secured in the free ends of a pair of rearwardly-extended arms j, fixed to rock with the vertical guiderod G.

The left end of the lower auxiliary heddle I has a sliding engagement with the verticallyreciprocating carriage K, as shown at 2' and the right end of the upper auxiliary heddle II has a sliding engagement with the lower auxiliary heddle I, as shown at 72,

The left main guide-rod G is rocked, thereby imparting a lateral movement to the upper auxiliary heddle H by a horizontallyswinging lever L, which is hinged at its rear end to a cross-bar a of the frame and which has at its forward end a pin-and-slot connection with a rearwardly-extended arm 9 fixed to the said rod G. This lever L is rocked back and forth by means of a cam c on the shaft 0 cooperating with the pins on the swinging lever.

The right main guide-rod G is rocked, thereby imparting a lateral movement to the lower auxiliary heddle I by means of a horizontally-swinging lever L, which is hinged at its rear end to the cross-bar a of the frame, the forward end of the said lever having a pin-and-slot connection with a rearwardlyextended arm g fixed to the guide-rod G. This lever is moved back and forth by means of a earn 0, carried by the shaft 0, cooperating with the pins on the swinging lever.

In the accompanying drawings I have shown the following means for imparting alternating vertical reciprocating movements to the main heddle and to the auxiliary heddles: Flexible connections 0 lead from the upper cross-bar of the main heddle F upwardly around pulleys 0, carried by one of the crossshafts a of the loom-frame, and from thence downwardly into engagement with one of the auxiliary heddles, in the present instance the lower auxiliary heddle I. A con necting-rod 19 leads from the lower cross-bar of the main heddle to the free end of a tappet P, hinged at its rear end to a cross-rod a of the frame, which tappet is operated by a cam c on the cam-shaft C. Retracting-springs Q, extend from the lower auxiliary heddle I down into engagement with a cross-beam a of the frame, which springs tend to draw the auxiliary heddles downward, and thereby the main heddle upward, thus holding the tappet P at all times in engagement with its controlling cam 0 To keep the main warp-threads at all times clear of the auxiliary heddles, I provide a lifter-bar R, which extends across the loom at a point to the rear of and a short distance above the auxiliary heddles. The lifter-bar R is hinged to a cross-bar a of the frame by suitable rods 7*. The lifter-bar It is moved upwardly and downwardly with the main heddle'by means of connections 0", leading from the lifter-bar R to the flexible connections 0 at points between the pulleys 0 and the top of the main heddle F. The lifter-bar R is permitted a slight yielding movement by interposing yielding springs r between the lifter'bar R and the flexible connections 0, this yielding movement of the lifter-bar R serving in a large degree to prevent the breaking of the main-heddle warp-threads.

It is.to be understood that any suitable jacquard mechanism maybe applied to my improved loom for controlling the times of the vertically-reciprocating movements of the main and the auxiliary heddles and also controlling the times of the independent lateral movements of the auxiliary heddles, so as to permit the loom to weave several patterns. As the said jacquard mechanism is well known, I have not attempted to illustrate the same in the accompanying drawings, but have simply shown a device capable of imparting to the said heddles their several movements, and by the use of the transverse eye bars or plates in the auxiliary heddles I am enabled to entirely do away with the use of needles in connection with the auxiliary heddles, thus simplifying the structure and reducing the cost of the loom very materially.

By the use of the lifter-bar I am enabled to keep the main-heddle warp-threads away from the auxiliary heddles, thus doing away with any liability to chafe.

What I claim is-- 1. In a loom, a vertically reciprocating main heddle and a plurality of vertically and laterally reciprocating auxiliary heddles, the said auxiliary heddles comprising a plurality of superposed bars or plates, each bar or plate having a plurality of eyes therein arranged to receive certain of the auxiliary warp-threads, substantially as set forth.

2. In a loom, a main heddle, an auxiliary heddle comprising a bar or plate arranged at an angle to the main heddle, the said bar or plate having one of its edges bent at an an= gle to the body of the plate and provided with eyes-for the passage therethrough of the aux- I iliary Warp-threads and means for operating the heddles, substantially as set forth.

ing the carriages laterally independently of each other, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres- I 5 ence of two witnesses, this 11th day of August, 1899.

ISAAC E. PALMER.
