I When any particular style of cloth is to be i Patented Feb. 18, 1930 UNITED STATES PATENT; OFFICE ARGHIBALD F. HOUSTON, OF SAGO, MAINE HEDDLE-HANDLING DEVICE AND PROCESS Application filed November 10, 1925. Serial No. 68,115.

This invention relates to the handling of heddles such as are used in the harnesses of looms, particularly those of the wire or sheetmetal type.

manufactured there must be arranged on the harness bars, a certain number of heddles corresponding with the number of warp threads which are to be raised and'lowered by that particular harness.

WVhen another type of cloth is to be made, it usually happens that there are either many more or many less warp threads, and this means either adding on or removing the same.

number of heddles.

The present practice is to count off the numher which are to be removed, and to then pull them off in a bunch. l/Vhen it becomes necessary to replace these, or any part of them, it is necessary to thread the harness bars carefully through each heddle loop. Thisis a very long process.

The purpose of this invention is to provide I an implement and a process by which the number of heddles to be removed, can be counted off at one end, and while still on the harness bar, be strung on a strip or preferably two strips or legs ofmeta-l upon which and with which they are then removed until needed. K

WVhen it is necessary to replace any number of heddles, this implement is used to replace them onthe'harness bars, and it can be used in such amanner that there will be no particular heddle the loop of which will not be positively threaded back where it belongs.

Fig.j 16 is a perspective View showing the application of my devices and implements to a leno harness.

In the drawings, F represents a harness j which ismade up of the wooden or metal bars 1 10 and 11 at the top and bottom connected by the end bars 12 and 13, through each of which, near the top and bottom, are the passages 18 for the top and bottom heddle bars 14 and15.

These heddle bars 14' and 15 are generally a flat metal and each projects at each end through a slotlS so that its locking hole 19 can be engaged by the end 17 of the wire locking device 16 of well-known type.

To remove or replace heddles, the locking devices 16 at one end, such as the left, are disengaged from the locking holes 19, and the heddle bars 14 and 15 are pushed as to the right until clear of their slots 18, at the left, when they are then brought back to the left over the bar such as 12. In this po sition the heddles H can be slipped off at the end or new heddles can be slipped on. 5 is the loop and 6 the eye of a heddle.

My preferred form of device includes a connecting bar A to the ends of which are pivoted as at 9 and 8, the heddle handling implements B and C. Each of these implements Band C includes two fiat parallel carrying strips 20. and 21 of unequal length,

arrow and sharpened at their tips so that they can slip in between the face of a heddle bar such as 14 and the metal 30 011 the side of the loop 5 of a heddle as shown clearly in Fig. 3.

The longer strip 20 is bent as at 24 near its point 22 towards the shorter, so that it will plow under or in between, and positively thread each heddle as it is passed along, as see Fig. 4. I

Preferably there are registering holes 25 in the free ends 22 and 23-, through which a fastening clip such as 26 can pass if desired, so that the heddles cannot slip off when the device has removed them from the harness.

WVhen it is desired to remove heddles, the two adjoining ends of the bars 14 and 15 are freed from the bar 12, and the points 22, '23 of strips 20 and 21 are slipped both on one side of bar 14, and the same is done with the lower set Con bar 15, as shown in Fig. 3, 13 and C being slipped in so as to carry a given number of heddles. They are slipp'ed'oli' carrying the heddles, and the bars 14and 15 are put back and locked in place. By means of clips such as 26 at one end, and the bar A at the other end, the removed heddles are locked in place until it is desired to replace them.

When it is desired to replace the whole or any part of them, the process i's reversed, care being taken to slip in the points 22 and 23, one on each side of'a bar such as 14.

If only a single carrying bar such as 63, shown in Fig. 6, were used in connection with a heddle bar 14, it would be possible for some particular heddle such as 61 to ride on 14 instead of being replaced in its proper position, and this would cause a great deal of trouble. It is on account of replacing heddlesthat I prefer to use parallel carrying strips or legs instead of single ones.

Instead of using a connecting bar such as A I may use single implements, each including two carrying strips or legs 20 and 21, having near the dull end, holes 27, through which a clip 28 can passto hold them together, and with the clip 26 which passes through holes 25,keep the heddles from slipping off the ends as shown in Fig. 7.

It is not necessary that the two carrying strips should be of unequal length nor that they should be pointed, although I prefer th'atconstruction. As shown in Figs. 8 and 9, I may usetwo fiat carrying strips and 71, through one end of which are: the rectangw lar holes such as 72 through which the clip 7 3 may be passed to hold that end together, and to prevent the strips from pivoting or swinging around.

The free ends 74 and 7 5 are sharpened or beveled but not pointed like an arrow.

In 'Fig. 10 I show a single flat strip '80 having at the blunt end 81 a stop 84"which may be permanent, and is to prevent theheddles I-I from slipping o'if,'while the other'end 82 is beveled or sharpened and may or may not be pointed. If desired there may be a hole 85 through this end to permit the passage of a stopping or holding clip 83 which can be takenout when threading the heddles, or

unthreading them, and put in place when they are being stored away.

As shown in Fig. 11, I may even use a flat strip 90 which has no stop and is not either sharpened or pointed.

Instead of a flat strip, I might, as shown in Figs. 12 and 13, use a round wire or rod 91, preferably pointed or sharpened or beveled at 92. As shown in Fig. 18, this might be passed in over the top of the heddle bar 14 inside the loop 5 of heddle H.

As shown in Fig. 14, I might use a halfround wire such as shown very much enlarged at 93. As shown in Fig. 15, I might use a strip 94 of U-shaped cross-section which could slide over the top and partly 'on each side of heddle bar 14.

In Fig. 16 I show the application of two of my devices, to what is known as a leno doup harness.

This comprises two harness frames 96 and 97, each of which has the usual Wooden'franre and end bars, and each of which has the top heddle bars 100 and 101, and bottom heddle bars 102 and 103.

The loops 105 of the main heddles 104 pass over these top and bottom heddle bars, and these main heddles are interlocked and arranged in a well-known manner.

Besides the main heddles there are also what are known as leno heddles 106, interlocked with the main heddles, and each 'having two legs, in the end'o'f each legthere being'a loop 107.

In handling such a leno arrangement I use two of my'devices 111 and 112, each with an implement in each end, with the top and bottom heddle bars 100, 101, 102, and 103, and

also two separate implements such as 1 15"and 116, which may be similar to those shown in Figs. 7, 8, 9, 10, or 11,12,13, 14, and 15, each being provided at each endwith-a stop suchas 117 or 118 which is preferably'a removable clip as shown.

I claim:

1. The combination in a heddle handling device, of a connecting bar pivoted at each end to a heddle handling implement which comprises'two fiat'carrying strips 'of unequal length, each pivoted at on'eend of thebar, and

at the other end "pointed and'sharpened, the longer strip being also bent near its point towards the shorter, and means near the pointed ends of each tokeep theheddles from ppin 0ft '2. The combination in "a heddle handling device, of -a connecting b'a r pivoted at each end to 'a heddle handling implementwhich comprises two flat carrying 'stripsof'unequal length, each pivoted at one end of the bar, and at the other end pointed and sharpened, the longer strip being also bent near its point towards the shorter,

3. A heddle handling implement which comprises two flat carrying strips of unequal length'fastened together at one end, the longer strip being bent near its free end towards the shorter and having stops near each end.

4. A heddle handling implement which comprises two flat carrying strips of unequal length fastened together at one end, the longer strip being bent near its free end towards the shorter.

5. The process of handling heddles which consists of passing a carrying strip through adjoining heddle eyes while said heddles are still on a heddle bar, and of then removing the carryingstrip with said heddles from the heddle bar. a

6. A heddle handling implement which comprises two flat carrying strips, with their flat faces adjoining, fastened together at one end and at the other end pointed and sharpened and having proximate said pointed and sharpened ends means to keep the heddles from slipping off.

7. A heddle handling implement which comprises two flat carrying strips with their fiat faces proximate each other, fastened together at one end, and at their other ends sharpened, together with detachable means near the sharpened ends to keep the heddles from slipping off.

8. A heddle handling implement which I comprises two flat carrying strips having their fiat faces substantially in contact throughout their length, both being sharpened at'adjoining ends and having stops near each end, the stop near the sharpened ends being removable.
