Application filed April 24, 1905. Serial No. 257,057.

fication.

My invention relates to looms, and more particularly to a reversingmotion for the take-up adapted to be used in connection with the well-known Knowles head-motion shown and described in Reissue Letters Patent No. 7,784 and with the system of reversegears shown and described in United States Letters Patent No. 398,328.

The object of my invention is to provide a mechanism adapted to be combined with and used in connection with said Knowles headmotion and said reverse-gear mechanism and with the take-up motion to reverse or move backward the take-up roll at the same time that the pattern-cylinders are reversed or moved back by said reverse-gear mechanism.

My invention consists in certain novel features of construction of my improvements,

as will be hereinafter fully described.

I have only shown in the drawings detached parts of the said Knowles head-motion and of said reverse-gear mechanism and of the driving-shaft of the take-up roll and my improvements combined therewith sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings, Figure 1 shows a detached part of said Knowles head-motion and said reverse-gear mechanism looking in the direction of arrow a, Fig. 3, and the upright driving-shaft and the shaft to the takeup roll and my improvements combined therewith. Fig. 2 shows a rear view of the gears and other parts shown at the lower part in Fig. 1 looking in the direction of arrow I), samefigure. Fig. 3 is a front end view of the parts shown in the upper part of FigIjl looking in the direction of arrow .0, same figure. Fig. 4 is, on an enlarged scale, a detached View of the operating-lever of the reverse-gear mechanism shown at the right in Fig. 1 and showing the reverse-gears in section. Fig. 5 isan end view of the parts shown in Fig. 4 looking in the direction of arrow (1, same figure, and showing the gears in full lines and the sliding key in section. Fig. 6 corresponds to Fig. 4, but shows the key and operating-lever in their opposite positions and also shows a modified construction of the locking-lever; and Fig. 7 corresponds to the lower part of Fig. 1, but shows a gear on the take-up-roll shaft meshing with a worm on the take-up-driving shaft.

In the accompanying drawings, 1 is a portion of the loom side or frame, 2 the stands secured upon the upper part thereof and supporting the several parts of the head-motion, and 3 the end of the arch. 4 is the lower cylinder-gear of the well-known Knowles head-motion, (fully shown and described in Reissue "Letters Patent No. 7,784,) fast on the shaft 5 and having teeth 4 ona portion only of its periphery. (See Fig. 3.)

On the inner end of the cylindergear shaft 5 is fast a bevel-gear 6, which meshes with and is driven by a bevel-gear 7, fast on the upright shaft 8. The upright shaft 8 has at its lower end a clutch mechanism of ordinary and well known construction and forming a part of which is a bevel-gear 9, which meshes with and is driven by a bevel-gear 10, fast on a driven shaft 11, in the usual and well-known way. (See Fig. 2.)

I will now describe the reverse-gear mechanism, which is of the same construction and operation as the reversegear mechanism shown and described in Letters Patent No. 398,328, above referred to.

Loose on the end of the cylinder-gear shaft 5 is a gear 12, which meshes with a gear 13 of the same size loose on the stud 14, fast in the frame 2. Secured to the gear 13, in this instance integral therewith, is a smaller gear 15 in line with a fourth gear 16 of the same size as the gear 15 and loose on the shaft 5 and adjoining the first-mentioned gear 12. Gears 15 and 16 are smaller than gears 12 and 13, so that when the gears 12 and 13 are in mesh the teeth of the gears 15 and 16 will clear each other. (See Figs. 4 and 6.) Gears 12 and 16 are retained on the end of the shaft 5 by a collar 17 and are slotted internally to receive the projecting end 18 on the key 18, which is adapted to slide freely in a slot or recess 5 in the outer end of the shaft 5 (see Fig. 6) and is provided with an engaging end or knob 18" and also an annular groove 18 for the purpose to be hereinafter described. The two gears 15 and 16 in this instance mesh ICO ICS

with the gear 19, fast on the endv of the shaft 20, on which is fast the harness-pattern-chain cylinder 21 and the box-pattern-chain cylinder 22.

When the loom is running normally, the key 18 is in its inner position to attach the gear 16 to the shaft 5,(see Fig. 4,) and the revolution of the shaft 5 through gear 16 rotates the gear 19 and the shaft 20 and the pattern- chain cylinders 21 and 22 thereon in a forward direction, the gears 15, 13, and 12 running loose. When the key 18 is in its outer position, (see Fig. 6,) the gear 12 is attached to the shaft 5 and turns the gear 13 and the gear 15, which in turn turns the gear 19 and shaft 20 and cylinders 21 and 22 in a reverse or backward direction, the gear 16 running loose, all in the usual and well-known way.

I will now describe my improvements combined with the reverse-gear mechanism above described.

The key 18 has an annular groove 18" at its outer end, as above stated, to receive an open-end collar 23, having studs 23 projecting from opposite sides thereof to enter the open-end slots 24 in the upper forked end 24 on the upper endof the centrally-pivoted lever 24, havin a hub 24 loosely mounted on a stud 25, ast in the end of astand 26, bolted to the frame 2. The lower end of the lever 24 has a stud 27 thereon to receive the hub 28 (see Fig.5) on one end of a connector 28. The other end of the connector 28 has a stud 28 thereon adjustably secured in the upper slotted end of one arm of an angle-lever 29, pivotally mounted on a stud 30 on the loom-frame. The other arm of the angle-lever 29 is connected by a link 31 with one end of a lever 32, having a hub 32 pivotally mounted on a stud 33 on the loom-frame. (See Fig. 2.)

The lever 32 has a forked arm 32", having 4 inwardly-extending pins thereon which eX- tend into an annular groove 34 in the hub of the bevel-gear 34. The bevel-gear 34 is fast on the upper end of sleeve 35, splined on the upright shaft 8 to revolve therewith and to move longitudinally thereon. On the lower end of the sleeve 35 is fast a second bevel-gear 36 of the same size as the bevel-gear 34.

A stud 37 is fast at its inner end to the loom-frame and extends out therefrom. (See Fig. 2.) The outer end of the stud 37 is turned down to receive the hub 38 of a double bevel-gear 38, which is adapted to mesh with the upper bevel-gear 34, as shown, when the loom is running normally or with the lower bevelgear 36 when the sleeve 35 is raised and the parts are reversing or running backward. The double bevel-gear 38 is also in mesh with a bevel-gear 39, the hub 39 of which is fast on the shaft 40, leading to the take-up mechanism. One end of the shaft 40 has a bearing in the stud 37. (See Fig. 2.)

The other end of the shaft 40 has a bearing in a box 41, secured to the loom-frame, and the extreme end of the shaft is provided with a hand-wheel 40. On the shaft 40 is fast a worm 42, which meshes with and drives a gear 43, fast on the shaft 44 of the take-up roll in the usual way.

In connection with the lever 24, attached to the sliding key 18, I preferably use a locking-lever 41, pivotally mounted at one end on a stud 42 on the stand 26 and havingv a projection 41 on its upper edge, preferably of wedge shape and preferably made integral with the lever 41, as shown in Fig. 3, which is adapted to be engaged by a projection 24 on the lever 24, said projection being preferably'of wedge shape. The projection 41 on the lever 41 is held in yielding engagement with the projection 24 on the lever 24 on one side or the other side thereof to yieldingly lock the lever 24 in its opposite positions, in this instance by a spiral expansion-spring 42, having its ends seated in bosses 43 on the stand 26 and the lever 41.

From the above description, in connection with the drawings, the operation of my improvements will be readily understood by those skilled in the art.

When the sliding key 18 is drawn out to reverse the direction of movement of the pattern- chain cylinders 21 and 22 through the reverse system of gears 12, 13, 15, and 16 in the ordinary way, the lever 24 will be moved out at its upper end and through connector 28, angle-lever-29, link 31, and lever 32 the sleeve 35 will be raised, as indicated by, broken lines in Fig. 1, to disengage the bevelgear 34 from the bevel-gear 38 and bring the bevel-gear 36 into mesh with the bevel-gear 38 to turn said gear in the reverse direction, and through said gear 38 the gear 39 and the shaft 40 to the take-up mechanism to reverse or turn backward the take-up mechanism, as will be readily understood by those skilled in the art. When the sliding key 18 is in its inward position in the normal operation of the loom, the lever 32 acts to lock and hold it in its inward position to prevent any accidental movement thereof. When the sliding key 18 is inits outward position, the lever 41 acts to lock and hold it, through the lever 24, in said position and prevent any accidental movement thereof. At the same time the lever 24 acts to support the sliding key 18 andhold it in its proper position.

In Fig. 5 is shown a modified construction of the locking-lever 41. In said figure instead of having the locking projection 41' made integral with the lever 41 said projection 41*" is made separate therefrom on a collar 41 adjustably secured on the lever 41 by a screw 41 or otherwise.

It will be understood that the details of construction of my improvements may be varied, if desired, and they may be adapted to be applied to any ordinary construction of head-motion and combined with the reversegear mechanism thereof.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-
