EDlVARD HOLLINGWVORTI-I, OF DOBCROSS, ENGLAND.
SPECIFICATION forming part of Letters Patent No. 469,210, dated February 16, 1892.
Application filed February 24, 1891. Serial No. 382,368. (No model.) Patented in England April 28. 1383,
To all whom it may concern.-
Be it known that I, EDWARD HOLLING- WORTH, a subject of the Queen of Great Britain, residing at Dobcross, in the county of York, England,have invented certain new and usefulImprovementsinSheddingMechanisms for Looms, ('for which Ihave obtained a patent in Great Britain, No. 6,301, bearing date April 28, 1888;) and I do hereby declare that the following is a full, clear, and exact descrip-' tion of my invention, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my'invention belongs to make and use the same.
My invention relates to looms, and more particularly to the harness and box-pattern mechanism of looms.
The object of my invention is to provide a simple, strong, and easily-operated mechanism for reversing the direction of the motion of the pattern-cylinder in the head-motion of the well-known Knowles loom, (described in United States Patent No. 134,992, dated Jan= nary 21, 1873,) while the direction of motion of the other parts continues forward.
My invention consists in certain novel fea tures of construction and operation of the mechanism above referred to, as will be hereinafter fully described.
Referring to the drawings, Figure 1 is a side elevation from the back of the head-motion of the Knowles loom above referred to, looking in the direction of arrow a, Fig. 2, showing a sufficient portion of said head-motion to illustrate my invention applied thereto. Fig. 2 is a partial section taken on line A B and also on line C D, Fig. 1, looking in the direction of arrow Z2, same figure. Fig. 3 shows a pin-wheel and star-wheel driving mechanism for the pattern-cylinder, which may be substituted for the gearing shown in Figs. 1 and 2. Fig. 4 is an edge view of the mechanism shown in Fig. 3 looking in the direction of arrow 0, same figure; and Fig. 5 is a detail of the shifting-lever for reversing the motion while the operator stands at or near the center of the loom.
In the accompanying drawings, 1 is a portion of the arch of the loom-frame 2, the frame of the head-motion.
3 is a bearing for the lower cylinder-gear shaft, (not shown,) 4 (see Fig. 2) is the harness-section, and 5 the box-section of the top cylinder-gear, said section mounted fast on a sleeve 6, fitted to turn freely in bearings 7 in the head-frame 2. Fast on the end of sleeve 6, at the back side of the loom, is a mitergear 8, which meshes with a miter-gear 9, fast on the upright driving-shaft 10, journaled in box 11 on an arm 2, which extends from the head-frame. The miter-gear 9 in turn meshes with miter-gear 12, fitted to turn freely on the end of shaft 13, which extends through the sleeve 6 to the front of the loom. The gear 12 has a long hub, which is fitted to turn freely in bearing 14 on arm 15, which extends from the cap of the box 11. (See Fig. 2.)
Fitted to slide freely on a feather 16, set in" shaft 13 between the gears 8 and Y12, is a clutch-hub 17, provided with pins 18, adapted to be moved into corresponding sockets 18 in the gears 8 and 12 by means of the forked arm 19, which engages the groove in t'he clutchhub 17 and which is faston the rod 20, which at its rear end slides freely in the stand 21,
extending up from the arm 15. Said rod 20 at its front end is jointed to arm 22 (see Fig.
rim 30, in which are cut notches 31, which serve as detents to hold the lever 27 in its extreme positions. the shaft 13 at the front side of the head motion is a pinion 32, which meshes with an intermediate pinion 33, loose on a stud 34:, fast on the head-frame 2. The intermediate gear 33 meshes in turn with gear 35, fast on the end of the pattern-cylinder 36, which runs in bearings 37 in the head-frame 2.
Then the clutch-hub 17 is moved by mean of the hand-lever 27 and intermediate connections into engagement with gear 8, the shaft 13 is driven by gear 8, turning the pattern-cylinder through gears 32, 33, and 35 in one direction, and when the clutch-hub 17 is moved in the opposite direction into engage- Fast on the front end of ment with gear12 shaft 13 is 'driven .by the latter gear, turning the pattern-cylinder in the opposite direction. It will be understood that when the clutch 17 is clear of both mitergears 8 and 12, as shown in Fig. 2, the shaft 13 will remain stationary, while the sleeve 6, carrying the harness-section 4 and box-section 5 of the top cylinder-gear, will be revolving, but when the Weaver operates the lever 27 and moves the clutch 17 through intervening mechanism, so as to bring saidclutch into'contact with the miter-gear 8 on the sleeve 6, the shaft 13 and sleeve 6 will revolve together in the proper direction. Then the Weaver requires to reverse the chain-cylinder 36 for the purpose of finding broken ends or picks, the lever 27 is moved in the opposite direction, so as to slide the clutch 17 out of engagement with the miter-gear 8 and into engagement with the miter-gear 12, whereby the shaft 13 is caused to revolve in an opposite direction to the sleeve 6. Consequently the motion of the chain-cylinder 36'through intervening connections is reversed. The sleeve 6 of the harness and box section of the cylinder-gear thereon is driven continuously by the miter-gear 9 on the vertical shaft 10 meshing with the gear 8; but the shaft 13 is only driven by the clutch 17 when it is moved into engagement with the mitergears 8 or 12, as required, the miter-gear 8 being the one which operates the parts when the loom is Working properly, and the mitergear 12 is employed only for reversing the parts.
In Figs. 3 and 4 I have shown a pin-wheel and star -wheel, which may be substituted for the system of gears 32, 33, and 35, (shown in Figs. 1 and 2, above described,) when it is desired to have the pattern-cylinder dwell and remain at rest between the indications instead of moving continuously. In said Figs. 3 and 4 the shaft 13 and pattern-cylinder 36 occupy the same positions as in Figs. 1 and 2. Fast on the end of shaft 13 is a pin-Wheel 38, which drives a star-wheel 39, mounted fast on t-hehub of gear 40, fitted to turn freely on a stud 42, fastin the head-frame. The gear meshes with gear 41, fast on the end of the pattern-cylinder 36. The proportion between the number of points in the star-Wheel 39 and the teeth in gears 40 and 41 is such that for each beat of the loom and each revolution of the shaft 13 the pattern-cylinder is turned through one angular space corresponding to the distance between two contiguous bars of the pattern-chain. (Not shown.) The same proportion is also maintained between the gears 32 and 35, Figs. 1 and 2.
The details of construction of the mechanism shown and described maybe varied somewhat, if desired.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a loom of the class described, the combination, with one of the cylinder-gears, a sleeve forming the shaft thereof, a miter-gear fast on said sleeve, driven by a miter-gear fast on the upright shaft, and said upright shaft and miter-gear, of apattern-cylinder, connections from said cylinder to a horizontal shaft, and said horizontal shaft extending through .the sleeve of the cylinder-gear, said shaft provided with a miter-gear loose thereon, driven by the miter-gear on the upright shaft, a sliding clutch, and means for operating the same to cause said horizontal shaft to be revolved with the upper cylinder-gear or to be revolved independently thereof, for the purpose stated, substantially as set forth.
