TAKE-UP MECHANISM FOR NARROW-WARE LOOMS.

SPECIFICATION forming part of Letters Patent No. 494,755, dated April 4, 1893.

` Application filed September 29, 1892. Serial No. 447,278 (No model.)

To aZ whom t may concern;

Be 1t known that I, ERNEST BURGESS, a citizen of the United States, residing at Paterson, v

in the county of Passaic and Stateof New Jersey, have invented a new and useful Improvement in Take-Up Mechanism for Narrow-Ware Looms, of which the following is a specication.

My invention relates to improvements in looms, of the class known as narrow-fabric or narrow-ware looms, and refers particularly to that part of the mechanism which receives and guides the ribbon or other fabric previous to its being deposited in the cradle, and known as the knee-roll.

The object of my invention is to provide a knee-roll capable of holding and drawing the ribbon or other fabric from the weavin g mechanism and depositing it in the cradle without aliowing it to be reeled upon the roll, the objection to the latter being that the accumulation of fabric upon the knee-roll causes the picking mechanism to pick the ribbon at gradually increasing intervals instead of evenly or at regular intervals.

A further object of my invention is to provide simple, efficient and easily operated means for adjusting the knee-roll upon its shaft, to take-up and let-ont the fabric when the latter becomes too loose or too tant, as the case may be.

A further object of my invention is to provide means to adjust the tension of the friction or feed-roll by which theribbon is held in contact with the frictional surface of the knee-roll.

Further objects and advantages of my invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings: Figure l is a perspective View showing the middle casting or bracket of a loom, the knee-roll shaft (a portion thereof) and one of the adjustable knee rolls mounted thereon. Fig. 2 is a longitudinal vertical section through the linee-roll and bracket taken in the plane of the shaft. Fig. 3 is a detail inside view of the rotary adjusting disk; and Fig. 4 is an end view of the knee-roll, with the adj usting disk removed and the hub'partly broken away, showing the setscrew and adjusting-pinion which is loosely mounted upon thesquared shank of said screw.

Referring by letter to the drawings, A designates the knee-roll shaft, constructed, arranged and mounted as in other looms of this class, the same passing at an intermediate point through the intermediate bearing, d, which is formed upon the middle casting or bracket, B. The box, A', in which saidbearing is formed is forwardly and rearwardly adjustable by means of an adjusting-bolt, c', which takes in a horizontal slot, A, in the casting or bracket. The other bearing boxes at opposite ends of the loom frame, in which this knee-roll shaft is mounted, (said bearings not being shown in the drawings) are provided with similar means for forward and rearward adjustment.

Orepresents a horizontal feed-roll supporting-shaft, parallel with the knee-roll shaft, which is loosely mounted at an intermediate point in a bearing, d, in the upper end of the standard, D, and at its ends in similar bearings in the ends of the loom-frame. This standard, D, is forwardly and rearwardly adjustable to move the feed-roll shaft, and is secured at its lower end to a horizontal bar, A', of the middle casting or bracket, said bar being provided with a horizontal slot, e, to receive a transverse bolt, el', which engages the vertical slot, e', in the lower end of the standard. By means of these intersecting slots and the adjusting bolt, the standard is capable of vertical as well as forward and rearward adjustment with relation to the knee-roll shaft. It is obvious that the bearings for the extremities of this shaft must be capable of similar adjustment, but as the forms of adjustable or sliding bearings are numerous, and as my invention relates solely to that portion of the mechanism which is directly connected with the knee-roll, l will conne myself in this description, to the construction of the middle casting or bracket, the bearings and attach ments carried thereby, and one of the knee-rolls carried by the kneeroll shaft, it being understood that a series of these rolls extending from one end of the shaft to the other (and all constructed as herein specified) is employed. Only one intermediate or middle cast-ing or bracket is necessary, as will appear from the following description.

The feed-roll shaft being loosely mounted in its severalbearings, as above specified, it

is capable of rotary adjustment to accomplish which I attach rigidly thereto the upper end of the tension-adjustinglever, E, thelower end of which is longitudinally slotted, as shown at f, to register with the yhorizontal -slot orv slots, f, in the transverse bar, G, of the easting or bracket, an adjusting bolt, F, engaging.V said slots to lock the levei at the desired adjustment. Mounted loosely upon the knee- 1011 shaft is the knee-roll, H,.provided with a.

is mounted looselyupon the shaft, and at the other end -by a .head-plate, L, which `is fixed tothe rolland is `provdediwith a hub, Z, which, also, is looselym'ountedupon the shaft. hub, Z, extends inward from the head-plate and is'provided with a radialtapped socket, fm, in which fits and operates a set-screw, M, having a squared or` angular shank,M. The head-plate is cu t-awayor recessed at L and in this recess stands a beveled adj Listing-pin,- ion, N, having a squared or angular bore, n, to receive and slidezupon the shank o f the set-screw. It will be noted that this .adjustingpinion-is held againstlateral movement by the Walls of the recess in which .it is arranged and-being fitted upon the shankof :the set-screw is capable of rotatontherewith, the longitudinal movement of the screw duri-ng said rotationnot affecting the position. of the pinion.

Secured `to the outer end of .thehub carried by the head-plate isa collar, O,whichis held-in place byscrews taking into thehub, and mounted loosely upon the hub, between the collar and the adjacent side of the kneerollis arotary adjusting wheel or disk, P, provided upon its inner surface with an annular gear,.Q, which meshes withthe teethrof the set-screw pinion.

The radial socket in which the set-screw is itted extendsto and communicatesv with the bore o f thehub, whereby when the set-screw is screwed inward it will bind or engage the shaft and lock the knee-roll lirmly'thereto. Therefore,by turning the adjusting wheel or disk, whichis connected by gearing to `the set-` screw, the knee-roll may be locked flrmlyto the shaft, or loosened therefrom, at will to perv mit 'the desired adjustment of said -roll in taking-up-slack of the fabric orletting-out the same.

The loose disk and the adjusting disk are arranged-as will be seen, at oppositeends of the knee-roll, and extend at their peripheries beyond the saine to forni guards or ianges to prevent the fabric from slippinglaterally.

A yoke, R, is connected to the feed-rollshaft` by means of-spring-coils, r r, preferably formed integral with the-arms, r" fr', of the yoke, the

The

'knee-roll may be regulated 'at the will of the operator.
