345,260. Controlling machinery guards. BLOMLEY, F., TOMLINSON, H., and TWEEDALES & SMALLEY (1920), Ltd., Globe Works, Castleton, Lancashire. Dec. 14, 1929, No. 38349. [Class 80 (iv).] In a device for coiling slivers in a carding-engine, combing-machine, lap machine, or the like, the separation or disengagement of the driving and driven wheels a', a<8>, Figs. 1 and 3, of the coiler mechanism must be effected prior to the opening of the coiler lid E and is independent of the movement away from its operative position of the member d<2> which, during coiling, prevents opening of the coiler lid, the disengagement also, if desired, serving to unlock the coiler door C. Two levers A, D are pivotally mounted on the coiler pillar B, one end of the ]ever A being formed with a hook a<1> and the other end being connected by a link a<2> to a lug or arm a<3> which passes through an inclined cam-slot a<4> in a boss a<5> attached to the pillar B, the inner end of the arm a<3> being fixed to a bush or sleeve a<6> in which is rotatably mounted the driving-wheel a7, the bush a<6> being slidable and rotatable in the boss a<5>. The lever D is formed at one end with two recesses d, d<1> and at the other end with a crank portion d<2> which is adapted to extend over the coiler lid E. It is also provided with a drop latch d<3>. When the wheels a<7>, as are in gear, the crank portion d2 extends over the lid E and prevents it from being opened, the hook a<1> occupying a position in the recess d<1> and abutting against the door C to maintain it shut. The drop latch d<3> is also moved to abut against the side of the lid E, as shown in Fig. 3, thereby preventing movement of the lever D which would disengage the hook a<1> and permit the coiler to be started with the lid closed. To unlock the lid E the latch d<3> is raised, Fig. 4, the hook a<1> disengaged from the recess d<1>, and the lever A turned about its pivot a, thereby causing the lug a<3> to travel along the slot a<4>, the wheel a<7> being disengaged from the wheel a<8> and the hook a<1> coming into register with an aperture c in the door C, which can then be opened. The hook a<1> also comes opposite the recess d in the arm D, which can then be turned, as in Fig. 4, to move the end d<2> clear of the lid E. To restart the coiler, the door C and lid E must both be closed and the parts moved back to the positions shown in Figs. 1 and 3.
