The sley also provides the mounting for the shuttle boxes and it carries the reed.

The object of this invention is to provide a sley of novel construction, which is particularly useful if the loom is required to run at high speeds. Other advantages of the invention will appear from the following description.

According to this invention a loom sley comprises a substantially tubular load carrying member to which are attached a raceboard plate and a reed support device. Either or both the attached devices may be permanently secured to the tubular member, as by welding, or they may be detachably secured as by screws or bolts. In any event the use of a tubular load carrying member reduces the manufacturing costs and lightens the sley so that it is easier to reciprocate at high speeds.

Preferably a reed cap carrier is also made as a tubular member arranged parallel with the sley and supported at or near its ends by the sley swords. Because of its tubular cross section, the sley cap carrier may be rotatably mounted on the sley swords, and this rotation may be used to clamp the reed between the support on the sley and the reed cap.

On construction of a loom sley assembly incorporating a sley and a reed cap carrier in accordance with the invention will now be described by way of example only, and with reference to the accompanying drawings, in which:

FIG. 1 is a perspective view of a loom sley, sley swords and shuttle box bases,

FIG. 2 is a sectional view through the sley in the vertical plane as indicated by the line II II in FIG. I, and

FIG. 3 is a further sectional view through the sley in the vertical plane indicated by the line III III in FIG. I.

Referring to the drawings, the loom has the usual pair of sley swords and 12 made as metal castings, and near its upper end, each sley sword has upper and lower

forward protrusions

14 and 16 respectively to mount the reed and the sley. Each lower protrusion 16 is in the form of a boss bored horizontally in the longitudinal direction of the sley 18. The upper protrusion 14 is in the form of a boss, bored parallel with, and to the same diameter as the lower protrusion I6, but with a slit 20 in the boss at the front. A clamping screw 22 passes through a clearance hole in the part 24 of the boss above the slit 20 and engages in a screw threaded hole in the part 26 below the slit, and has a handle 28 at its upper end. By turning this screw 22 it is possible to close the bore in the upper protrusion slightly for clamping purposes.

The sley 18 is fabricated, and the basic element is a tubular steel member 30 which is of adequate dimensions to carry the loads applied to the sley in use. This member is a fit in the holes formed in the lower protrusions of the two sley mounds l6, and is locked in these holes by locking screws 32 passed through holes the front of each of these protrusions, and engaging in screwed holes in the tube itself.

A race board 34 is fixed to the topside of the tubular load carrying member 30. The raceboard is made of a steel plate 36 having short ribs 38 screwed to its underside at spaced apart positions. Each rib 38 has a concave recess in its underside so that it is a snug fit on to the curved surface of the tubular member 30, and a setscrew 40 passes through each rib 38 from the topside and through a clearance hole in the tubular member into a nut 44 on the inside of the tubular member 30. This nut is shaped to fit into the curved bore of the tube and is prevented from rotating thereby.

The sley is completed by a reed support 46, which is mounted on the rear of the tubular member 30. This support comprises a thick metal strip 48 disposed with its width vertical and detachably secured to the tubular member by bolts 50 passed through clearance holes in the strip and through special distance pieces 52 concave on one side to fit on the curved surface of the tube. The bolts 50 engage with nuts 54 on the inside of the tube similar to those used to fix the raceboard 34.

A groove 56 with inwardly tapering sides is formed along the top edge of the strip 48 and the bottom bar 58 of the reed 60 is received in the groove. Strips 62 of plastics material are stuck to the front and rear faces of this groove to provide a slight degree of resilience in the reed support.

A reed cap carrier 64 is also made of tubular steel and as its cross section dimensions are the same as those of the sley tube, it can be cut from the same size of tubing. This tube 66 is fitted in the split bosses 14 at the upper ends of the

sley swords

10 and 12, and has the reed cap 65 along its rear side.

The cap 65 is identical with the reed support 48 on the sley 18 excepting that the Vee groove 67 for the top bar 68 of the reed 60 is formed in the underside of the sley cap, and a handle 70 is fixed to the cap and projects vertically upwards near to each end of the cap.

To fit the reed 60, the clamping screws 22 on the upper bosses 14 of the

sley swords

10 and 12 are released, and the cap carrier 64 is turned about its own longitudinal axis to lift the cap away from its operative position. The split bosses 14 act as bearings to allow the cap carrier tube 66 to rotate in them, and this is only possible because of the cylindrical crosssection of the cap carrier. The reed 60 can then be placed with its bottom bar 58 in the Vee groove 56 of the reed support 46 on the sley, and then the cap carrier 64 turned to engage the Vee groove 67 of the cap 65 on the top bar 68 of the reed 60. With the reed located between the support 48 and the cap 65, the clamping screws 22 are tightened so that the carrier is locked and therefore the reed is locked.

The tubular member 30 of the sley extends on the outsides of the sley swords l0 and 12, so that the shuttle box bases and 82 which have bosses 84 and 86 respectively can fit on these projecting ends of the tubular member. Screws 88 pass through clearance holes in the bosses 84 and 86 and engage in screwed holes 90 in the end portions of the tubular member 30.

I claim:

I. A loom sley comprising a substantially tubular load carrying member; spaced swords fixedly attached to said load carrying member; means for mounting a reed assembly comprising reed supporting means mounted on said load carrying member, a reed cap carrier member mounted on said sley swords for rotation relative thereto, and a reed cap carried by said reed cap carrier member; a reed assembly extending between said reed supporting means and said reed cap, and releasable locking means for locking said reed cap carrier member against rotation relative to said swords to retain said reed assembly on said sley between said reed supporting means and said reed cap, said locking means being releasable to permit rotation of said carrier member relative to said swords and thereby permit removal of said reed assembly from the sley.

2. In the loom sley defined in claim 1, said reed assembly mounting means comprising opposed recesses along said reed supporting means and said reed cap carrier member adapted to receive upper and lower bars of said reed assembly.

3. In the loom sley defined in claim 1, said reed cap carrier member comprising a cylindrical tube mounted parallel to said tubular load carrying member in spaced releasable clamps on said swords.

4. In the loom sley defined in claim 1, a raceboard secured to said tubular member.
