REED.

Original application filed February 18, 1925, Serial No. 9,958. Divided and this application filed May 28,

This invention relates to reeds for looms, the subject matter of this application having been divided out from my application Serlal No. 9,958 filed February 18, 1925, for looms. The loom disclosed in that application is particularly intended for weaving heavy relatively stiff material such as strands made from strips of paper formed into cord or twine. In that application the pick-laying is shown as accomplished by the use of a length of chain carrying a strand gripper which is passed through the shed in one direction and returned outside of the shed, the reed being so constructed to guide the chain during its operative traverse through the shed. For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figure 1 is a detail partly in section on line 11 of Figure 3 of the pick-laying mechanism showing the reed.

Figure 2 is a plan, parts being removed, of the same mechanism.

Figure 3 is a section on line 3-3 of Figure 1.

The shedding mechanism comprises a lay having a reed 61 extending thereacross at its upper end. This reed, as best shown in Figure 1, comprises an angle plate having vertically extending spaced slots 63 therein in its vertical flange through which the warp strands pass. Positioned against and fixed to the forward face of this plate and above the horizontal flange which extends forwardly thereof, are a pair of plates 65 slotted to mate the slots in the reed. The slots in the plates 65 extend inwardly from their adjacent edges which are turned forwardly and then vertically toward the opposite plate 65 so as to form a series of fingers 66 positioned opposite to the solid portions of the reed between the slots, and defining therewith a guideway 67 substantially channel-shaped in cross section and presenting an open slot lengthwise thereof on its forward face between the opposed ends of the fingers 66 on the upper and lower plates. The lay extends some distance beneath the reed and carries at its lower end a substantially channel-shaped guideway 68 arranged parallel to the upper guideway and extending across the machine, this channel-shaped guideway also having a length- Serial No. 194,869.

wise extending slot in its forward face similar to the slot of the upper guideway.

Beyond the ends of the lay are guideway sections 70 similar to the guideway 68 and forming continuations at either end of the guideway 67 formed by the reed 61 with the plates 65. The upper and lower guideways 68, Y67 and 70 have positioned at either end thereof sprocket wheels 7 5, the teeth 76 of which project into the guideways in position to engage at suitable times a length of sprocket chain 80 which may be projected thereby through the upper and lower guideways in an endless path. -At each end of these guideways is arranged a curved guide member 81 surrounding the periphery of the corresponding sprocket wheel 75 and acting to hold the chain in engagement with the teeth of the sprocket wheels so that the chain is received by each sprocket wheel from one of the guideways, is carried about its circumference, and then projected in the reverse direction into the other of the guideways. It will be noted that the chain 80 is not continuous, but is of a length sufficient to engage its end portions only with the two sprocketwheels at one time so that when it is passed into engagement with either of the sprocket wheels about a substantial portion of its periphery, it is entirely out of contact with the other sprocket wheel. This chain carries the device for engaging the strand of filling material to lay it in the shed, this device shown at 85, extendin through the open slot, passlng between the fingers 66 of the plates 65, thus passing through the shed as the chain is in the upper guideway to lay the pick and returning beneath the shed as the chain returns through the lower guideway.

The pick-laying mechanism per se is not claimed herein, being covered by the parent application of which the present application is a division.

Having thus described an embodiment of this invention, it should be evident to those skilled in the art that various changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.

I claim:

1. A reed comprising a plate slotted to re ceive Warp strands, and having a spaced pair 2 r iyrarsae of series of fingers proecting forwardly between said slots, the rec ends of opposed fingers of the series projecting toward each other to produce a guideway substantially channel-shaped in cross section with a narrowed slot at its forward face and constructed to guide a filling laying member through the shed.

2. A reed comprising a back plate slotted to receive warp strands, a pair of spaced front plates positioned against the front face of said back plate each having slots mating the slots in said back plate, their adjacent edges being turned forwardly and then toward each other to form opposed series of fingers be tween said slots to produce a guideway substantially channel shaped in cross section with a narrowed slot at its forward face.

3. A reed comprising a back plate slotted to receive warp strands, a pair of spaced front plates positioned against the front face of said back plate each having slots mating the the shed.

stantially channel-shaped in cross section' with a narrowed slot at its forward face, said back plate being extended forwardly beneath said front plate.

4. A reed comprising an angle member having a vertical flange slotted to receive the warp strands and a pair of series of fingers projec ting forwardly between said slots above the horizontal flange of said angle, the free ends of opposed fingers of the series projecting toward each other to form a horizontal guideway with a narrow slot in its forward face for guiding a filling laying member through signature.
