I SLIDING HOOK FOR LOOM HARNESSES Filed Jan. 28, 1937 k6Z INVENTOR. E 1K BY GEORGE E BAHAN ATTORNEY Patented Jan. 24, 1939 UNITED STATES PATENT OFFlQE SLIDING HOOK FOR LOOM HARNESSES Application January 28, 1937, Serial No. 122,823
8 Claims.
This invention relates to harnesses for looms. It is particularly applicable to that type of harness frame in which besides the usual heddle bars upon which the heddles are supported, there are supporting bars attached to the top and bottom wooden frame bars upon which there are slidable hooks, links or connecting members between such supporting bars and the heddle bars, the connecting members being slidable on one or 0 both bars.
This type of device is generally used on harness frames for rayon and silk weaving, the purpose being to keep the regular heddle bars straight and stiff.
There are now types of connecting members, links or hooks which cannot be removed from the supporting bar until the bar itself is removed but from which hooks the heddle bar can be removed, but my device is a sliding hook or separable link consisting of two legs pivoted together in such a way that by separating these legs, the device can be removed from both the supporting bar and from the heddle bar.
There may be one supporting bar at top and bottom or two bars as shown. The word top as used herein refers to whatever is nearest the top wooden frame bar such as shown in the drawing, and the arrangement at the other side between the frame bar, supporting bar and heddle bars is the same when the frame is turned upside down, the bottom becoming the top.
In the drawing, Fig. 1 is an elevation of a complete harness frame showing only some of the heddles, and being broken in places for compactness.
Fig. 2 is an enlarged sectional view on the line 2-2 of Fig. 1.
Fig. 3 is a view similar to Fig. 2 showing how the sliding hook can be released.
Fig. 4 is an isometric View showing how, when the sliding hook is released, it can be removed.
Fig. 5 is an enlarged sectional view on line 5-5 of Fig. 2.
Fig. 6 is an enlarged isometric end view of a slightly modified hook.
Fig. 7 is a view similar to Fig. 2 of a modification.
Fig. 8 is an enlarged view as from the right of Fig. '7.
Fig. 9 is a view similar to Fig. 4 showing how a hook such as shown in Fig. '7 can be removed.
Fig. 10 is an enlarged sectional view on line l0l9 of Fig. 7.
Fig. 11 is a view similar to Fig. 2 of another modification.
Fig. 12 is an enlarged top view of the hook shown in Fig. 11.
, In the drawing, Frepresents a harness, the frame of which is made up of the ends 29 and 2| which, as shown, are of metal and of the top and bottom frame bars 22 and 23 which are usually and are shown as of wood.
H, H represent heddles which are strung as usual on heddle bars B, B. Each heddle bar B, as shown, is supported at its ends 24 and 25 by the end frame bars 20 and 2| and in the middle by the hooks A, A, each of which is supported by and is slidable along a. supporting bar S which, as shown, is of rectangular cross section. Each supporting bar S is fixed to and supported by the top frame bar 22 or the bottom frame bar 23 respectively by screws such as 26, 26.
Each sliding hook A, as shown, is made up of two legs I and 2 closely pivoted together by a rivet or pin 3, each having on each side of the pivot, rectangular recesses 30, 3t and 48, 4|, the recesses 30 and 40 being of such size that when the members I, 2 are closed, they will lock the device in place slidably on bar S and at the same time, the recesses 3| and 4| will come together and closely fit the bar B.
As shown, the bottom end of each leg I and 2 is so cut away as to leave a tab 32 or 42 by which the scissors-like hook A can be opened and preferably there is also at this end, a projection 33 and a recess 43 whereby when the legs I and 2 are brought together, they will be locked in position.
In Fig. 6 is shown an alternative construction of the bottom ends 34 and 44 of the legs in which the locking devices and opening devices are omitted.
In Figs. '7, 8, 9 and 10 are shown a modified form of hook C wherein legs H and 12 are pivoted at one end l3 and the rectangular notches 50, 5|, 52 and 53 are of a size to embrace the bars S and B respectively. Leg II, as shown, is of U shape and leg I2 fits inside the sides of the U when the device is closed.
- These legs are shown as having a pivot l3 at the top, and tabs I4 and H3 at the bottom to facilitate opening. There is also a projection l6 which engages a recess I! to' lock the device in closed position.
In Fig. 11 is shown a hook D made of the legs 6| and 62 pivoted at 63 at the bottom instead of at the top, and having the rectangular recesses 64, 65, 66 and 61, but with no projections and no locking means.
As shown in Fig. 11. supporting bar K and heddle bar L are of the same size and recesses 64, 55, B6, 61 are of the same size so that hook D can be used, with the pivot 63 at the bottom, or at the top as desired.
As shown in Fig. 12, leg 62 is of U shape but leg 61 need not penetrate to the bottom of the groove 68 and if the parts fit snugly, there is no need of any locking device such as 16 and I1.
I claim:
1. The combination with a harness frame having top and bottom frame bars and a supporting bar fixed to one of the frame bars and parallel therewith; of a heddle bar for supporting heddles which is parallel with the supporting bar; and a sliding hook comprising two legs each made of fiat metal of greater width than thickness pivoted medially together, the legs having oppositely disposed rectangular recesses in their edges near each end, one set of adjoining recesses embracing a supporting bar and the other set embracing a heddle bar, there being a projection on the fiat side of one leg and a corresponding depression on the other leg to lock the legs in closed position.
2. The combination with a harness frame having top and bottom frame bars and a supporting bar fixed to one of the frame bars and parallel therewith; of a heddle bar for supporting heddles which is parallel with the supporting bar; and a sliding hook comprising two legs each made of flat metal of greater width than thickness pivoted together, the legs having oppositely disposed rectangular recesses in their edges near each end, one set of adjoining recesses embracing a supporting bar and the other set embracing the heddle bar.
3. The combination with a harness frame having top and bottom frame bars and a supporting bar fixed to one of the frame bars and parallel therewith; of a heddle bar for supporting heddles which is parallel with the supporting bar; and a sliding hook comprising two legs each made of flat metal of greater width than thickness pivoted together, the legs having oppositely disposed recesses in their edges near each end, one set of adjoining recesses embracing a supporting bar and the other set embracing the heddle bar.
4. A sliding hook for heddle frames comprising two legs each made of flat metal of greater width than thickness pivoted together by a pivot through their wider faces, the legs having two sets of oppositely disposed rectangular recesses in their narrow edges, one set near each end.
5. A sliding hook for heddle frames comprising two legs pivoted together, one leg being of U shape in cross section and the other leg fitting into the U, the legs having two sets of oppositely disposed rectangular recesses, one set near each end.
6. A sliding hook for heddle frames comprising two legs, each having at each end oppositely disposed rectangular recesses in their edges, the legs being so pivoted together that when the legs are closed, the recesses form rectangular bar holes, both parallel with the pivot.
'7. A sliding hook for heddle frames comprising two legs, each made of flat metal of greater width than thickness, pivoted together by a pivot through their wider faces, the legs having two sets of oppositely disposed rectangular recesses in their narrow edges, one set near each end, whereby when the legs are closed, the recesses form rectangular bar holes, both parallel with the pivot.
8-. A sliding hook for heddle frames comprising two legs, each having at each end oppositely disposed rectangular recesses in their edges, the legs being so pivoted together that when the legs are closed, the recesses form rectangular bar holes, both parallel with the pivot, one leg having a looking recess and the other leg having a locking projection to engage the recess.
