T0 all 1.071.077?, it may concern,.-

Be it known that I, WILLIAM L. KEENE, a

citizen of the United States, residing at Wa-y terville, in the county of Kennebec and State of Maine, have invented an Improvement in Drawing-In Frames, of Which the following description, in connection with the accompanying drawings, is a speciiication, like characters on the drawings representing like parts.

improvement of such apparatus in severalv particulars whereby the work is facilitated and simplified, the apparatus being adapted for drawing-in ordinary cotton-harnesses,har 2o nesses having metallic detector-heddles, or a combination of harnesses and detectors for warp-stop-motion mechanism.

The various novel features of my invention will be hereinafter described,and particularly pointed out in the following claims.

Figure l is a left-hand side elevation of a drawing-in frame embodying one form of my invention. Fig. 2 is a front elevation, centrally broken out to save space, of the appa- `golratus illustrated in Fig. 1, four harnesses with metal detector-heddles being shown in position for drawingin. Fig. 3 is an enlarged detail of the upper right-hand portion ot` the apparatus,showing its use with cotton-harnesses and stop-motion detectors. Fig. iis a transverse sectional detail on the line Fig. 3, looking toward the right. Fig. 5 is an enlarged perspective detail ot' the two parts of the Slasher-comb separated. Fig. 6 is a similar view of the two-part friction-clip for the warp ends. Fig. 7 is a front elevation, broken out, of one of the guide-rods; and Fig. 8 is a similar view of one of the supporting-bars on which the metal detectors or detector-heddles are strung.

The main frame is composed, essentially, of sides A, having upturned extensions A', terminating in overhanging arms A2, connected rigidly by cross braces or girths As A4 A5, the latter forming a guide at the top of the frame over which the warp-threads w pass from the the latter from rotation during the drawing- 6o in process.

When a beam is ready to be drawn in, the threads are passed through a Slasher-comb, as is well known, a section of the Slasher-comb being shown in Fig. 5, the comb proper, O, being detachable from a cap C', which is adapted to receive the free ends of the comb retaining the threads in place, and after the latter have been drawn in the com b is separated, as shown in Fig. 5, to remove it from 7o the Warps. I have herein shown the overhanging arms A2 as connected at their ends by two parallel cross-bars a, set on edge and somewhat separated to form a guide for depending hangers B, the head b of each hanger (see Fig. 4) being shouldered to receive the lower edges of the guide members a, and a threaded stud b is upwardly extended from each hanger through a clamp member b2, which straddles the members a, and a suitable clamping-nut b3 is screwed upon the stud above the clamp b2.

It will be obvious that each hanger may be moved laterally upon the guide when the nut b3 is loosened, and the hanger can be firmly 85 held in laterally-adjusted position by tightening the set-nut, this lateral adjustment enabling me to set the hangers at such a distance apart as will conform to the length of the supporting-bar of the harness or series of 9o detectors, as the case may be.

Each hanger B is shown as having a reentrant portion B', in which is formed an inclined seat B2 for the Slasher-comb, as clearly shown in Fig. Li, and below the seat the hanger is provided with an upright bearing portion B2, having in its lower end preferably a vertical slot 3, (see Figs. 2 and 3,) for a purpose to be described, and back of such bearing and at its lower end the hanger is provided with a curved seat Bl for a purpose to be described.

IOO

A support (shown as a horizontally-extended arm D) is secured to each hanger above the Slasher-comb seat by means of a pivot stud dx, which passes through the hanger and has mounted upon its inner end a clamping-nut d.

Referring to Fig. 1, the supportD is shown as provided with two slots d in one edge and with similar slots, as d2,in its other edge, four of the slots d2 being shown in Fig. 1. A slide E is mounted on the upright bearing portion B3 of each hanger and held in vertically-adjusted position by means of a clamp-nut e on a threaded stud eX, which passes through the vertical slot 3 in the hanger and the slide E, each slide having a horizontally-extended arm e',having its upper edge notched, as at e2.

Supposing now that it is desired to draw in a set of harnesses having metallic detector-heddles-sueh, for instance, as shown in United States Patent No. 536,969, dated April 2, lS95--then the supports D will be set by means of the clamp-screw d in the position shown in Figs. 1 and 2, with the notches d2 uppermost, and the supporting-bars h, one of whichis shown separately in Fig. 8, will be taken out of the harness-frames,with their detector-heddles hX thereon, and laid in the slots d2, as shown in Figs. 1 and 2, so that the heddles hX depend from the bars h, substantially in the manner they depend when in the harness-frame, the warp-eyes h' coming substantially opposite to the warp-threads just above the Slasher-comb and in convenient position for the operative to pass the drawing-in hook through the warp-eye to engage a thread and drawit in through the said eye, the loosely-held detectors permitting a slight side twist or slant of each one as the operative inserts the hook through the eye in usual manner.

In Figs. 1 and 2 four sets of detector-heddles are shown in position for drawing in, and in order to separate the lower ends ofthe series of heddles and to further facilitate the manipulation thereof during drawing in a series of separator-rods s are mounted iu the notches e2 of the arms e/ between the series of heddles, as best shown in Fig. 1, the separator-rods s preferably being notched at one end, as at s, (see Fig. 7,) to engage one of the arms e to prevent accidental longitudinal movement of the rods, which would tend to dislodge them from the arms.

The operation of drawing-iu is performed in usual manner, the operative drawing in through the dierent heddles in accordance with a certain order.

It will be obvious that instead of drawing in four harnesses two harnesses could be drawn in or three or, in fact, agreater number could be drawn in by simply lengthening the supports D and providing a greater number of the slots d2 in their upper edges.

rlhe supporting-bars h for the heddles are usually made as shown in Fig. 8, with a notch h2 in each end to enable them to be locked into the harness-frame, and I utilize this construction to lock the bars in position in the4 drawing-iu frame.

A locking-arm d5 is pivoted at d6 on one of the supports D and is adapted to swing upward and rearwardly into the notch h2 at that end of the heddlesupporting bar to prevent longitudinal movement of the said bars during drawing in, one of such locking devices being suflicieut to retain the supporting-bars in place.

If the harness-frames are wide, then the hangers B are laterally adjusted, as has been described, to bring the supports D into proper position to receive the cross bars h, and if the harness-frames are narrow then the hangers are brought closer together in accordance therewith, so that whether the harness be wide or narrow the drawing-in frame herein shown isY equally convenient.

Some detector-heddles are longer than others, and by the vertical adjustment of the slides E, I am enabled to locate the separators s at the most convenient point for properly separating the lower ends of the banks or series of heddles while the warps are being drawn in.

When the warp-beam is mounted in the drawing-in frame the warp ends hang below the Slasher-comb, and various means haveV been heretofore employed for temporarily holding the ends until the particular threads have been drawn into the harnesses, as otherwise the drawing in of one thread usually results in lifting up with it a number of other threads, tending to form tangles or knots, and I have devised a warp end clamp or holder which engages the warp ends below the Slasher-comb and holds them in place, yet without preventing the drawing in of the threads one by one as the work progresses.

The clamp or holder is herein shown as composed of two parts ff', the latter preferably a cylindrical rod adapted to fit into a concave longitudinal groovef2 in one edge of the barlike memberf, the opposite longitudinal edge of the latter being round, as at f3. The warp ends are passed between the membersff, and the latter are brought together, thus pressing the threads into the concave lgroove f2, and in this position the clamp is set into the seat B4, which, as shown in Figs. 1 and 4, is curved to correspond to the curvature of the external longitudinal edges of the clamp when the latter is in operative position. The clamp is passed into the seat through the opening or throat 5 and then given a partial turn to wedge it more or less tightly between the opposing walls 6 and 7 of the seat, the degree of pressure exerted on the warps by the two members of the clamp being determined by the tightness withrwhich the clamp is set into its seat.

Of course the pressure upon the warpthreads must not be great enough to inter- IOO IIO

fere with the ready withdrawalof the warp ends as the several threads are drawn into the harnesses, the clamp oifering sufficient frictional resistance for the required purpose.

Not only does the clamp act in the manner described, but it also serves to keep the warp ends spread out in a thin sheet substantially as they pass through the comb.

The drawing-in frame is equally adapted for drawing in cotton-harnesses alone or cotton-harnesses to be used in connection with drop-detectors for stop-motion mechanism* such, for instance, as shown inUnited States Patent No. 639,182, dated December12,l899.

To provide for cotton-harnesses, I have mounted on each of the arms D a yoke-arm M, having at its free end a seat m to receive the cross-bars or supports` as h6, of cottonharnesses H, Figs. 3 and 4;, the harnesses depending from the yoke-arms, which latter are pivotally connected to the supports D by threaded pivot-studs mx, which pass through longitudinal slots m' in the yoke-arms and are provided at their inner ends with clamp-nuts m2, the slots m' enabling me to adjust the yoke-arms vertically to bring the warp-eyes h7 of the cotton harnesses into proper position for drawing in, and also to be in alinementV with the warp-eyes of drop-detectors if such are used.

. It will be noted by reference toFigs. 1 and 2 that the yoke-arms are turned down out of the way, and this is eected by reversing the position of the supports D.

InI Figs l and 2 the supports are shown in position with the notches d2 uppermost; but when drawing in for cotton-harnesses the clamp-nuts d are loosened and the supports D are just reversed and brought into the position shown in Figs. 3 and t,with the notches d/ uppermost for a purpose to be described.

When drawing in wit-h cotton-harnesses, it is unnecessary to use the separators s, and the slides E are lowered, as shown in Figs. 3 and et, out of the way, the rods s being dispensed with.

It is usual to arrange the detectors in two banks or series for convenience when such detectors are used with plain harnesses, and in order to draw in the threads through the detectors,as well as the harnesses,the supporting-bars, as tx, on which the detectors t are strung, are supported endwise in the slots d' of the members D, as clearly shown in Figs. 3 and 4C, the detectors then depending between the Slasher-comb and the harnesses H, with the warp-eyes t of the detectors substantially in the horizontal plane of the heddleeyes By means of the vertical adjustment ofthe yoke-arms the heddle-eyes are adj usted relatively to the eyes of the detectors.

From the foregoing description lit will. be manifest that the drawing-in frame herein shown and described is conveniently adapted for various kinds of work and the operation of drawing in is greatly facilitated by the convenient arrangement and construction of the novel parts of the apparatus, so thatirrespective of the particular form of harness the drawing in can be readily performed, and the frame is particularly adapted for drawing in when some kind ofwarp-stop-motion mechanism is employed.

Having shownl one practical embodiment of my in venton, the same is not restricted thereto, as various modifications orchanges may be' devised by those skilled in the art Without departing from the spirit and scope of m'y invention.
