This invention relates to warping apparatus wherein a warper receives its supply of strands from a Creel. The invention is particularly applicable to high speed warping apparatus Vwherein the many supply strands run through the creel under no substantial frictional drag other than is caused by unwinding from their supply masses; in this connection my invention provides mechanism acting in an improved manner automatically to clamp the many strands adjacent to their respective supply masses during periods of stoppage of winding. My invention has for one of its objects to provide improved mechanism whereby a large number of strand clamps can be automatically applied at approximately the instant the winding mechanism of the warper ceases to turn, and can be automatically released at approximately the instant the winding mechanism begins again to turn, In the interim between these operations the clamps are adapted to hold the many strands against entanglement should any of them be brushed or touched by the operator in repairing strand breakages or in like operati0ns. My invention further provides in its preferred form for avoiding any application of the clamps prior to complete stoppage of the winding mechanism of the warper, and any delay in release of the clamp after starting of the winding mechanism to turn. Thus any tensioning of the moving strand is avoided, the clamps serving only to hold the strands while they are stationary.

Fig. 1 is a fragmentary side elevation of a machine of the present invention;

Fig. 2 is a plan view of the parts shown in Fig. 1; and

Fig. 3 is a perspective view of one of the upright frame members of the creel of Fig. 1, showing the arrangement thereon of one of the yarn clamps and a controlling member therefor.

Each side section or half of the frame of the creel preferably includes outer vertical angle irons 11 connected at their tops and bottoms by longitudinal, horizontal frame members 12 and 13, and inner vertical angle irons 14E connected by like longitudinal memoutwardly projecting brackets 21.

bers, one of which is indicated at 15 in Fig. 2. Theouter and inner sets of frame members are preferably tied together by transverse members such as indicated at 16. These transverse members 16 may conveniently eX- tend across and similarly connect corresponding frame members of the opposite side section of the creel, leaving an intervening space or runway for the operator between the two sections or sides. Since the creel may be symmetrical, only one of these sections or sides is illustrated.

The inner vertical angle irons 14 conveniently serve as supports for vertically spaced'pins, pegs or spindles 18 adapted to receive unwinding supply strand packages or rmasses M. From each such mass the unwinding strand runs to a porcelain eye 18 extending through the corresponding outer angle iron 11. After passing through this eye 18, thestrand runs to the front end of the creel, passing through a guide eye in one or more Passing from the front of the creel to a warper 8O Or other strand manipulating apparatus, all of the ends (including usually those from both sides of the Creel) are collected into a sheet or web S by any suitable guiding means, such as a pair of rolls 23, 2-1 and suitable reed 25; this sheet or web as here illustrated runs onto va winding beam 81 which is suitably driven by a rotating drum 82 in the warper. The controlling mechanism of the warper may be of any desired type.

Means is provided or clamping each of the many strands in the creel at a point adjacent to its supply mass. Preferably such clamping means takes the form of individual clamps, each disposed at the point at which the strand just leaving its supply mass oins the group of strands leading to the front end of the creel. In the preferred form of the invention7 such a clamp utilizes as a stationary or backing member the above-described porcelain eye 19 (F 3) through which the strand first passes. A movable member adapted to clamp the strand against this eye 19 preferably consists of a circular piece of metal 30 of about the same diameter as the eye 19. To force the member 30 against the strand extending through the eye a light spring 37 fastened to the upright 11 at .32 is arranged to bear against the rear face of this member 30. The member 30 may be supported by this spring by means of any suitable Connection, preferably a universal tilting connection which insures that the member 30 will seat with certainty on the strand which extends through the eye 19. As illustrated the member 30 is connected to the spring 37 by a pin 34 fastened to the member 30, passing loosely through a hole 35 in the spring, and headed at 36. The spring 37 thus tends to urge the member 30 to clamp the strand; during the progress of unwinding the spring 37 and attached member .30 are held away from the eye 19 to permit the strand to pass freely through the eye Without any clamping action.

As part of the controlling mechanism for simultaneously operating the Clamps, the Creel preferably includes vertically disposed rotatable rods 40, (Figs. 1 and 3) each having a pin 41 projecting therefrom in position to engage the inner surface of the corresponding spring 37, to move the spring and member 30 away from the eye 19. As shown in Figs. l, 2 and 3, each of the outer vertical angle irons 11 carries one of these rotatable rods, the rod in each case resting on a suitablestep or supporting bracket 42 which projects from the lower part of the angle iron, and is rotatably held in the corner defined by the two flanges of the iron by suitable vertically spaced clips 43. The numerous rotatable rods 40 are preferably bent at their tops to form crank arms 45 which are engaged by reciprocating rods 50 extending along the top of the Creel. These rods, which may be suitably articulated if necessary, are connected by a link 51, arm 52 and shaft 53 to an arm 54, so that movement of this arm 54 in one direction causes all of the rotatable rods 40 to remove the Clamping members 30 from contact with the guide eyes 19, while movement of the arm 54 in the opposite direction has the effect of applying all of the clamps of the creel.

For automatically Controlling the Clamps in this manner, the device preferably includes detecting means in connection with the warper and adapted to respond to stoppage and starting of the rotation of the warper, this detecting means preferably taking the form of speed-responsive mechanism, for example of the centrifugal-governor type, connected to the warper.

Referring to Fig. 1 such speed-responsive mechanism is shown as comprising a pair of small weights 84, carried by arms 86 and 87 respectively, which are pivotally mounted on a head 88 rotatably driven through a shaft 89 and gearing 90 from the main shaft of the warper, turning with the drive roll 82. The arms 86 and 87 carrying the weights 84, 85 are connected by links 93 and 94 to a vertically movable sleeve 96. rlhese connections are such that upon rotation of the driving drum 82 of the warper, the weights 84 and 85 will move outward slightly, causing the sleeve 96 to rise; the reverse operation obviously takes place upon stoppage. Preferably these parts are suitably counterbalanced, as by a spring 97 with such delicacy that the sleeve 96 responds to slow rotation of the warper drive roll, that is, immediately the warper drive roll starts to turn, the sleeve 96 rises. 'The sleeve 96 is connected in any suitable manner to a lever 101 pivoted at 102 and in turn connected by a link 103 to the above described arm 54.

lt will readily be apparent that my invention in its broader aspects is not dependent upon the particular form of the speed responsive device or of the particular nature connections are operated in the reverse direction to apply all of the clamps in the creel, thus securing'all of the strands against entanglemcnt.

lt should be understood that the present disclosure is for the purpose of illustration' only and that this invention includes all modifications and equivalents which fall within thel scope of the appended claims.
