Specification of Letters Patent.

Patented July 7, 1914.

Application filed. March 26, 1912. Serial No. 686,396.

To all whom it may concern:

Be it known that I, FRED A. WVHITMORE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Looms for Weaving Tufted or Chenille Fabrics or Carpets, of which the following is a specification.

My invention relates to looms for weaving" tufted or chenille fabrics or carpets, ordinarily termed chenille Axminster looms, and my invention relates to improvements in the class of looms referred to, and particularly.

to improvements in the needle frame operating mechanism, and the chenille weft carrier mechanism, and the mechanism for operating the same.

The object of my invention is to improve upon the ordinary construction of the nee-- the fabric, is prepared beforehand, and is placed in the fabric as weft, in parallel rows transversely of the fabric, in the shed of the binder warps. The chenille weft, which is also termed fur, is sometimes carried into the shed by shuttles, and sometimes, as in my present improvements, by a fur or chenille weft carrier, which consists of a tube suitably supported, and through which the chenille weft passes, and mechanism for operating said tube automatically at predetermined intervals, after the shed for the fur or chenille is opened, and the binder or catcher warps for the chenille are in their upper position.

I have only shown in the drawings a detached portion of a chenille Axminster loom with my improvements combined therewith, suflicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :'-Figure 1 is a front view of a portion of the left hand end of achenille Axminster loom, and of the fur carrier mechanism, and operating mechanism for the needle frame; the operatmg rack is partially shown in section. Fig. 2 IS an end or side view of the fur carrier mechanism, shown at the upper part of Fig. 1, and looking in the direction of arrow 4, same figure; for the sake of clearness the bearings and stands are not shown in this figure.

Fig. 8 shows the operating disk shown at the left in Fig. 2, detached, and in a different position. Fig. 4 is a plan view of the parts shown in Fig. 2, looking in the direction of arrow 6, same figure, and, Fig. 5 1s a sectional end view, on line 5, 5, Fig. 1, looking in the direction of arrow at, same figure.

In the accompanying drawings, 1 is the loom side or end frame, 2 is the lay, see Fig. 2, and 3 the reed thereon, preferably open at its upper end. 7

, 4 is the breast beam plate over which woven fabric 5 passes.

6 are the binder warps, which are raised and lowered by two harnesses, not shown, in the usual way. 7 are the catcher warps which bind the chenille weft, and which, from the fell of the fabric, pass through the eyes S at the lower ends of vertically e tendmg needles 8, and then upwardly to catcherwarp spools, not shown, in the usual way.

9 is the needle frame, which has upwardly entendlng projections 10 at each end, see Fig. 1, which enter recesses in the guide frame 10, secured to the loom side. The needle frame 9 has up and down movement communicated thereto by mechanism on the loom, to be hereinafter described.

11 is the driving shaft, and 12 is the crank shaft of the loom.

All of the above mentioned parts may be of any well known construction in the class of looms referred to.

I will now describe my improvements in the needle frame operating mechanism, and the fur or chenilleweft carrier mechanism, and mechanism for operating the same.

The projection 10 at each end of the needle frame 9, has ears brings 10 thereon, see Fig. 1, to which is pivotally connected the upper end of a downwardly extending connector 1-3. The lower end of said connector 13 is mounted on the wrist of the crank 14 on the crank shaft 14, which is suitably mounted in bearings at the lower portion of the loom side 1. The crank shaft 14 has a e plurality of cranks 14 thereon, for oper-- i see Fig. *5.

' ating the needle frame, and has the pivotwhich is adapted to engage with its peripheryxa roll '21 mountedon a stud 22 on a horizontally extending lever 22, which is pivotally mounted at its inner end on a, stud 22 on a bracket on the frame 1, The outer end of the lever 22.

i pivotally connected to the lower end of an upwardly extending connector 23, see" Figs. 1 and 5. The upper end of the con-' nector 23'is pivotally connected to a stud 24 on a slide 25, see Figs. land 2, which slide is suitably guided on the guide frame 10 The revolution of the crank shaft 12, through intermediate connections, communicates an up and down movement to. the slide 25, and also, through intermediate connections, communicates a rotary movement to the crank shaft 14 and the crank 14 thereon, and when the needle frame 9 is in its upper position, as shown in Fig. 1, the slide 25 isin position to start the operation of the fur carrier, scribed.

26'is the fur or chenille carrier, see Fig. 1, having extending therefrom toward the breast beam, a tube 26, through'which the chenille weft, not shown, passes in the usual way. The fur carrier 26 is mountedv on two rods 27 and 28, which extend transversely across theloom in the direction of its width, and has a sliding movement on said rods, in the usual way. An endless cord. 29 is attached to. the fur carrier 26,

.and passes over pulleys 30 and .31, see Fig 4, and around a drum 32 atone end of the loom, which drum has grooves in its periphcry, and around a grooved wheel or pulley at the other end of, the loom, not shown, in the usual way. The drum 32 is rotated, first in one direction, and thenin the ,other direction, through a'crank and rack operating mechanism. v I

The drum 32 is mounted on a shaft 33, which has a pinion thereon, not, shown, which meshes with and is drivenby a gear 34, seeFig. 4, mounted'on a shaft 35, which is suitably mounted in bearings, and in the rack guide 36, see Fig. 1. The shaft 35 has a pinion 37, mounted;thereon, see Fig.

A spur gear 18, which in to be hereinafter de-- 1, which meshes with and is driven by a rack 38, which is suitably guided in the rack guide 36. The rack 38 is provided with a stud 39, see Fig. 4, to which is pivot -ally connectedone end; of a-horizontal connector 40; the other end of said connector 40 is connected to the wrist of the crank 41 of a crank shaft 41, which is suitably mounted in bearings 42,43, and 44, see Fig. 4.

A disk 45 has its hub 45 secured on the crank shaft 41. The hub 45 of the disk 45 has lugs or ears 45, thereon, see Fig. 4, on

which are pivotally mounted one end ofxthe.

locking fingers 46, which are guidingly held :at their ends by the projection 45 on the disk .45. Helically coiled expansionsprings .47, inclosed in bosses 47 on the disk 45, "(only one spring is shown in'Fig. 4,) are adapted to yieldingly move the fingers 46 toward a seconddisk 48, when said'fingers ;are released, as will be hereinafter described. The disk 48 has its hub 48 loosely mounted 011 the shaft 41, and said hub 48 is carried in a bearing 44, and has fast ithereon, on itsouter end, the hub 49" of a -gear 49, which gear meshes with and is con- Ist'antly driven by a-pinion 50 on a shaft 51. The shaft 51 carries a gear 52, which }meshes with and is driven by a pinion 53 on 25 thereon, see Fig. 2, which carries a pin. :54, adapted to engage and move upwardly one arm of a horizontally extending lever @55, see F1g..4. The other arm of the lever has pivotally connected to its. end the ,upperuend of aconnector56, see Fig.2.

The lower-end of the connector 56 ispivotially connected to one arm of an angle lever 57, which has its hub pivotally mounted, on a stud 57 The other arm of said anglev lever 57 has pivotally connected thereto one end of a horizontally extending connector 58; the other end of-sald connector 58.is

pivotally connected to a downwardlyex tending arm of a lever 59, whichhas its hub 59'v centrally mounted on a stud 60, see Fig. 2. The upwardly extending. arm of the lever 59 has pivotally attached thereto one end of an arm or lever. 61, which extends toward and abovethe disk .48. The

arm or lever 61 has a hook projection'61 thereon, which is adapted to engage with the upper engaging end of a cam lever-62, which has its lower end pivotally mounted on a stud 63, see Figs. 2 and 3. Ahelically coiled contraction'spring 64, attached at i one end to the lever 61, and-at its other end to the cam. lever 62, acts to yieldingly, hold the hook arm 61 in engagement with the end of the lever 62.

The lower end of the lever 59 has pivotally connected thereto one end OfCEtOQIl nector 65; the other end of said connector 65 ispivotally connected to the lowerendof an arm 66, which has its hub 66' pivotally mounted on a stud 67, see Figs. 2 and 8. The arm 66 has pivotally mounted thereon one end of an arm or lever 68, which has a hook projection 68 thereon, adapted to engage with the end of a downwardly extending lever 69, which is pivotally mounted on a stud 70, see Figs. 2 and 3. A helically coiled contraction spring 71 is attachedat one end to the lever 68, and at its other end to the cam lever 69, and acts to hold the hook arm 68 in engagement with the end of the lever 69.

Through the upward movement of the slide 25, and the intermediate connections, above described, to the levers 62 and 69, said levers 62 and 69 are moved away from the disks and 48, as shown in Fig. 3, and are caused to be disconnected from, and to release the fingers 46, pivotally mounted on the disk 45, as above described, to allow said fingers, through the action of the springs 4?, to be moved toward the disk 48. The disk 48 has an inwardly turned rim, which is provided with notches 48; (one of these notches is shown in Fig. 1), which notches are adapted to engage the fingers 46, and through said fingers, cause the revolution of the disk 48 fast on the crank shaft 41, to operate said crank shaft 41 and the crank 41, and through the connector 40, move the rack 38 to operate the cord drum 32, and the fur carrier 36. On the continued revolution of the disk 48, in the direction indicated by the arrow in Fig. 3, the fingers 46 engage the ends of the hooked arms 61 and 68, to operate said arms, and move them out of engagement with the ends of the levers 62 and 69, to allow said levers 62 and 69 to move back into the position shown in Fig. 2. The levers 62 and 69 have the cam-shaped or inclined edges 62, (only one is shown in Fig. 1), which, in engaging the fingers 46, will move lock it at each end of its rotary travel, a

cam 72 is provided, which in this instance is mounted on the end of the crank shaft 41, and is shown by broken lines in Fig. 2. The cam '72 is adapted to engage a roll 73 on a lever 74, said lever 74 has its lower end pivotally mounted on the loom side at 74', see Fig. 2. A helically coiled contraction spring 7 6 acts to hold the roll 7 3 against the cam 72, to hold the crank 41, when it is in its end position, as shown in Fig. 8.

It will be understood that the details of construction of my improvements may be varied 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 type referred to, a chenille weft carrier, a guide for the same, a flexible connection from the carrier to a drum, and said drum, means for operating said drum, said means including a crank shaft, a crank thereon, gearing connected to the drum, and a connection from said crank to said gearing, means to operate said crank shaft, said means including a member fast on said shaft, and, a driven member loose on said shaft, and connections intermediate said members, to cause them to move in unison to rotate said crank shaft and said drum, at predetermined times.
