Title: Improvements in or relating to balances
IPC: G01G1/26
Filed: 1959-04-23
Abstract: 866,022. Weighing apparatus. METTLER, E.. [trading as METTLER, FABRIK FUR, ANALYSENWAAGEN, E.], April 23, 1959 [Jan. 31, 1959], No. 13883/59. Class 143 A balance having an asymmetric beam provided with a counterpoise, a carrier which can be placed on an end knife edge of the beam which carrier has brackets for supporting weights placeable therein by a control mechanism and also carries a scale pan, and an arresting mechanism including a movable slide which when raised lifts the carrier off the beam and the beam off its pivot, is so constructed that, when the slide is raised, the carrier, the beam and the slide are all included in the load on a rough-weighing balance. For fine weighing, the beam 3, counterweighted at 5, pivots on the fixed frame 1 of the apparatus about the contact of knife edge 4 with supporting surface 2 and the end knife edge 7 of the beam supports the carrier which consists of the parts 8, 9, 10 and 11. The rod 11 supports both the scale pan 12 and brackets 13. 14 each of which consists of three horizontal arms arranged at 120 degrees intervals around the rod. Two sets of annular weights, 15 to 18 and 19 to 22 respectively, are placeable on the brackets 13 and 14 according to the setting of a control mechanism. This consists of lifting members 23 to 30 raisable by levers 31 to 38 so as to lift off the carrier brackets, when the balance is in the fine weighing condition, these weights whose lifting members are in the raised position. The sum of the weights remaining on the brackets plus the load 50 are made to balance the counterweight, the inclination of the beam being indicated at 6. The weights of each set are multiples of a given unit of weight and are placeable on the carrier brackets by the control unit in a sequence of steps each of which differs from the next by one such weight unit. The unit of weight in the lower set is ten times that of the upper. More than two such sets may be provided. The arresting mechanism consists of a slide 41 raisable by rotation of shaft 39 to disengage cam 40 from the forked lower end of the slide. In the lower position 40<SP>1</SP> of this cam the balance is in the fine-weighing position described above. In the position shown in full lines, the slide has been raised to allow upstanding sets of three pegs 47, 48 respectively to lift the carrier off the beam and the beam off its pivot. The connection of the slide 41 to the fixed frame 1 is by means of the flat springs 42, 43, 45, 46 of equal length and the intermediate rigid member 44. Thus not only is the slide guided for vertical erection only but also the whole of the load on the slide is balanced against the stress in the springs so that indicator 51 of the relative displacement of the slide and the fixed frame 1 serves to provide a rough measure of the value of load 50 in order that the control mechanism may be pre-set to the approximately correct value for fine weighing. In the extreme upper position 40<SP>11</SP> of the cam both the fine and rough balances are arrested.

Title: Improvements in or relating to weft feeding mechanism of looms for weaving
IPC: D03D39/00
Filed: 1931-05-14
Abstract: 378,113. Selecting and presenting wefts in shuttleless looms. GLASS, J. P., Meadowcroft, Balcombe Road, Horley, Surrey. May 14, 1931, No. 14341. [Class 142 (ii).] In the manufacture o f fabrics such as carpets or rugs wherein different kinds of wefts are used, weft from a number of bobbins is led to a table mounted on a reciprocating carriage at each advance of which one of a series of levers, independent of the carriage and selectively actuated by electrical means, is placed in the path of the carriage to bring it to rest with the selected weft thread opposite a striker by which the weft is presented to the weft carrier. A carriage M, Fig. 1, carrying a table P with slidably mounted weft guiding tubes p<1>, is reciprocated on rails K, K<1>, by means including a connecting-rod f<4> operated by a motor F, the rod J<4> being pivoted to a crosshead m<6> which has a frictional engagement with rails m<4>, m<5>, on the carriage. A series of levers N, pivotally mounted on a stationary frame, are associated with a corresponding series of magnets J, any one of which can be energized when an electric circuit is closed bv the action of its corresponding pattern needle. When a magnet is energized, the corresponding lever N is rocked and an arm n<4> is positioned to engage and stop the carriage M, the lever N being automatically locked in operative position by a spring catch n<1>. The frictional mounting of the crosshead m<6> permits the latter to continue its movement after stoppage of the carriage and, at the end of the stroke, the engagement of contacts m<7>, r<4>, on the crosshead and rail K respectively, energizes a magnet R and operates a striker r<2> which engages the selected tube and causes the desired colour of weft to be presented to the carrier. The rocking levers N are released on the return stroke of the crosshead m<6> by the engagement of contacts m<8>, s<7> on the crosshead and rail K respectively, the closing of the circuit energizing an electromagnet s<8> and moving a rod S to dislodge the locking members n<1>. The weft protruding from the selected tube is gripped between a plunger t<12>, Fig. 2, and an abutment t<15> forming part of a rotating member T which is mounted for axial movement under the influence of a face cam t<6> and a spring t<8>. Rotation of the member T causes the weft to be drawn across the weft inserter or carrier W and withdrawal of the selected tube p<1> rocks a lever V to effect its release, a knife Y being provided to sever the pick from the supply.
