Title: Improvements in runners and bolt tails of latches
IPC: E05C1/16
Filed: 1945-06-01
Abstract: 593,528. Latches. PARKES & SONS, Ltd., J., BUTTER, F. J., and FRYER, E. C. June 1, 1945, No. 13753. [Class 44] The rear end of the runner or bolt tail of a latch bolt for a one- or two-horned follower is allowed a certain amount of lateral movement, and is guided by a follower horn, so that friction between the horn and the abutment on the runner is reduced. For example, in Fig. 1, a latch bolt B engages with a runner C which has a wide slot c at its rear end for the boss d<1> of the two-horned follower D ; this slot c is wider than the diameter of the boss d<1> so that the runner can move up and down relatively to the boss ; the ends of the projections c<2> left by the slot c are pressed up to form concave lugs e, e<1>, the inner faces of which are engaged by part-circular ends f, f of the follower horns. When the runner is in its forward position it is supported by both horn ends but when it is operated, one of the horn ends guides and supports the runner. Alternatively, the lugs may have their curvature reversed, or they may be replaced by pins, to be engaged by concave surfaces at the horn ends. In Fig. 7 pins f<4> extend from the horns and bear rearwardly against curved smaller ends of triangular slots e<4> in the runner, the dotted circles representing their respective extreme positions. In Fig. 9 the rearward projections c<2> have lugs comprising bent-up tongues e<5>, e<6> forming angles in which the rounded horn ends f engage. Each tongue e<5> may have an inwardly extending portion e<7> bent closely behind the tongue e<6> to strengthen it. In Fig. 11 the projections c<2> have their rear ends bent to form plain lugs e<8>, and their outer edges bent to form flanges e‹ against the inner surfaces of which the rounded horn ends can engage ; the flanges e<9> may have tongues e<10> bent closely behind the lugs e<8> to strengthen them. In every case the abutments on the followers and on the runners may be formed by casting or stamping. The invention is also applicable to a latch in which Palace Motion is used, i.e. the follower has two horns, one engaging an abutment on the bolt tail or runner, the other engaging with one of two horns of a bell-crank lever or second follower, the second horn of which engages another abutment on the bolt tail or runner.

Title: Improvements in or connected with filling feeler devices for weft replenishing looms
IPC: D03D51/34
Filed: 1919-06-10
Abstract: 141,552. British Northrop Loom Co., (Northrop Loom Co.). June 10, 1919. Weft-feeler arrangements.-A weft-feeler device for causing weft replenishment when the weft is substantially exhausted comprises a penetrating member 19 which has two spaced penetrating points 17 and is carried by the impinging head or member 15 of a feeler slide 6. Normally, the member 19 is caused to project through a slot in the member 15 by the action of an adjustable bolt 25 tapped into a finger 21 acted upon by a spring-controlled bolt 30, so that when the lay beats up, if weft is present in working quantity opposite both or either of the points 17, the points 17, or one of them, sink into it. The member 15 then engages the weft mass, and both members 15, 19 are moved frontwards, in the relative position shown in Fig. 2, against the action of a spring on the stem 9 of the feeler slide, the finger 21 remaining raised. When the weft is substantially exhausted opposite both points 17, the bobbin engages the member 19 and moves it inwards before engaging the member 15, thus turning the finger 21 about its pivot 20, as shown in Fig. 4, so that when the members 15, 19 are moved frontwards as the beat-up continues, the finger 21 engages a part 14, which controls automatic weft replenishment.
