Title: Improvements in or relating to sawing machines
IPC: B27B3/00
Filed: 1935-11-11
Abstract: 455,175. Reciprocating-saw machines. STECHSCHNEIDER GES., 9, Schellingstrasse, Berlin. Nov. 11, 1935, Nos. 31175 and 31177. Convention dates, Nov. 9, 1934 and Feb. 27, 1935. [Class 145 (ii)] In a reciprocating-saw machine for sawing wood, metal, cork, leather, synthetic materials, fabric, cloth, felt, rubber sponge, &c. and particularly for sawing patterns such as dial plates from wood, metal, artificial resin, bone, nacre, ivory, &c., the upper end of the saw blade 8 is clamped at 9 in a holder 10 which reciprocates in a sleeve 13 secured, as by screws 13<a>, in a cross-bar 11 detachably secured at its ends to supports 12 secured as by screws 12<a> to the work-table 1 ; a spring 14 bears at one against the cross-bar 11 and at the other against a nut 15 threaded on the member 10, a washer 15<a> and counter nut 16 being provided. Rotation of the holder 10 is prevented by a groove 17 and pin 18. The blade 8 passes through a slot 2 in the circular insert 3 in the table 1 and its lower end is secured in a holder 5, 6, 7 reciprocated by a motor 4. A slider 20 on the cross-bar 11 carries a rod 19, the lower end 19<a> of which is forked and holds the work down at each side of the blade. A second slider 24 on the cross-bar 11 carries a rod 23 having a pointed end 23<a> which serves to centre the work when making curvilinear cuts; a scale is provided on the bar 11 for setting the slider 24. In a modification, Fig. 6, a number of blades 48 are used ; each of the reciprocating holders is provided with a rod 42, and the blades, which are provided at their ends with notches or holes to receive the rod 42, are spaced by members 46 also mounted on the rod 42, the end of which is threaded and carries a nut 47 which is prevented from rotating by contact of one of its faces with the holder ; the end of the rod 42 has affixed thereto a member 44 having a handle 43 by which the rod 42 can be rotated, causing the nut 47 to move axially to clamp the blades ; a nut member 45 having a handle 45<a> is mounted on the projecting threaded part of the rod 42 to secure it in position. The Specification as open to inspection under Sect. 91 describes a blade holder, Fig. 7 (Cancelled) and Fig. 8 (Cancelled) which comprises a main member 26 having a shank 27 which is clamped in the saw-reciprocating member; alternatively, the member 26 is integral with said member; the blade is clamped against the member 26 by an auxiliary member 33 having laterally extending lugs 34 received in lateral recesses 29a in the bodv 26 and projecting beyond it ; a spindle is passed through holes 35 in the lugs and is rotated by a handle thereon so that an eccentric portion formed thereon bears against a groove 32 in the body 26, whereby the part 33 is drawn tightly against the part 26 to clamp the blade. The part 26 has pins 31, 31<a> fitting borings 36 in the port 33, these pins serving to position the blade, the back of which may be notched to engage one of the pins. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to telegraph installations
IPC: H04L25/00
Filed: 1934-10-31
Abstract: 442,613. Printing telegraphy. NATIONALE TELEPHON - UND TELEGRAPHENWERKE GES., 136, Mainzerlandstrasse, Frankfort-on-Main, Germany. Oct. 31, 1934, No. 31271. Convention date, Oct. 31, 1933. [Class 40 (iii)] In a double-current system in which the voltage-source of the transmitter at each station is divided into unequal parts B1, B2, Fig. 1, the polarized receiving relays PR at the two stations are permanently in the line and the transmitter contacts sk are brought into circuit by switches Z during the transmission of a message. Thus, no current flows in the line during rest periods, but when switches Z have both been operated so that the transmitters are in circuit through contacts 2, the two 6-volt batteries B1 B<1>1 aid one another so as to apply a 12-volt spacing potential to the line. When transmitter contact sk is marking, however, the 18-volt battery B2 opposes the 6-volt battery B1, so that a 12-volt marking potential is applied to this line. Current may be derived from a potentiometer Pot, Fig. 2, fed by alternating-current mains NA through rectifiers G1 and a filter Dr or from directcurrent mains through a similar filter (part of Fig. 2, not shown). The speed of the printer motor M is controlled by a centrifugal contact F1k, the state of which is indicated by a lamp Gi. Preparation of local circuits. When a key ET of the keyboard is depressed the bar U actuates the pawl K and so causes the distributer SV to be driven by the motor M. At the same time, a contact ek is closed and magnet ZM is energized so that a switch Z, of the kind described in Specifications 420,820 and 420,853, is thrown. This switch closes at 1 the circuit of the motor M (which for economy is fed with unrectified current), brings the transmitter contact sk into circuit with the line at 2, and completes at 4 the circuit of the local receiving relay EM which operates the printer and is controlled by the time relay PR. The signal set up by the combination bars KS on the distributer SV is then sent over the line L by the distributer, which is constructed as described in Specification 389,999, the contact sk being actuated by the distributer cams so as to send the required combinations to line. The first combination comprises five negative impulses to allow for preparation of the receiver circuits. At the receiving station the switch Z is tripped when the start signal, comprising the unopposed 18 volts of battery B2 of the sending station, causes the relay PR to short-circuit the condensers CF and so to energize the magnet ZM. Thereupon switch Z at the receiving station is thrown and the 6 volts of receiving battery B1 is opposed to the 18 volts of sending battery B2.

Title: Jack selection mechanism for circular knitting machines
IPC: D04B15/68
Filed: 1956-10-15
Abstract: 848,084. Knitting. FIDELITY MACHINE CO. Inc. Oct. 7, 1957 [Oct. 15, 1956], No. 31310/56. Class 74 (2). In knitting a tuck patterned stocking leg and foot two-feed, selected ones of needles 4, which have all drawn yarn at feed B and are approaching feed A at tucking level, are raised to clearing height by, in each case, the appropriate one of cams such as 13-16 which act on the main butt 61 or 59 of the associated needle jack; and certain consecutive ones of the jacks bear also each an auxiliary butt 62 by which, when the cam associated with the main butt is in transit between positions of insertion and retraction, those jacks are nevertheless raised, the auxiliary butt coacting with another of the cams which is, during the whole of the transit stage, fully inserted. Thus, by temporarily taking over the work of the main butts, the auxiliary butts perform two functions. First, they provide for withdrawal of the cams of the series in the middle of two long butt jack series 51 or 52, without leaving any of the jacks in a partly elevated position. Secondly, they divert from the path of an ingoing cam, those main butts which would otherwise interfere with its insertion. The jacks associated with the short butt heel needles have long main butts and those associated with the long buttinstep needles have short butts. The auxiliary butts are shorter still. Fig. 7 shows a tuck pattern which repeats every fourth wale and every four revolutions of the needle cylinder. Each wale-wise strip of the pattern will therefore be formed on a group of four needles and thus, on a four-hundred needle machine, the last tuck stitch of a complete pattern cycle would normally be formed on the needle immediately preceding that one which forms the first tuck stitch of a cycle. To avoid the formation of two adjacent tuck stitches, the jack 53 associated with one of these two needles is, unlike all the others, provided with two long butts, by one or other of which it is always raised to clearing level and therefore never tucks. The cams 13-16 are inserted in two stages, against the action of springs 23, by a rotary bank of cams, such as 8, 9, 11 and 12, acting through levers 17, 18, 19 and 21. They may be inserted collectively by a cam on a pattern drum, acting, through linkwork, on a plunger 24. Another cam on the pattern drum may cause angular displacement, about the axis of the rotary cam bank, of a plate 29, and so cause bosses 31 to ride out of apertures 32 in a support plate 33, to lift the cams of the bank up their spindle 34, against the action of a spring 35, out of engagement with the levers 17. Specification 788,107 is referred to.

Title: Improvements relating to weighing scales
IPC: G01G1/26
Filed: 1919-12-16
Abstract: 158,775. White, A. E., (Toledo Scale Co.). Dec. 16, 1919. Pendulum-weight apparatus; computing-apparatus.-Relates to that type of pendulum-weight apparatus in which there is provided a computing chart having two sets of weight graduations and over which is carried an index-finger inscribed with two price per-unit-weight scales, the apparatus being of the type described in Specification 21587/07. In the present invention, means operated by the turning of a knob are provided for adding an additional weight to the pendulum in order to increase the weighing capacity of the machine and for adding simultaneously a counterweight to the weigh-beam to avoid displacement of the zero position of the indexfinger, the turning of the knob also changing the reading-fans of the index-finger and the instruction notice as to which of the figures are to be read. Supplementary means ensure the complete travel of the additional weight towards or from the pendulum. For increasing the weighing capacity, a dumb-bell shaped weight 13, Fig. 5. is allowed to fall from its inoperative position by the swing of the supporting-arm 27 which is operated by the turnings of the shaft 28 by an external knob. At the same time the supporting- arm raises the pivoted guide rails 18 in such a way as to cause the weight 13 to enter into and be supported by the pendulum-weight 9. The arm then allows the guides to fall in order that the pendulum weight may carry alone its increased load.. The supplementary means 42 for ensuring the completion of the travel comprise telescoping rods and a helical spring actuated from the shaft 28, provision being made for lost motion as between the knob, the shaft, and the telescoping rods to secure freedom of action. An upward extension 85, Fig. 10, of the rods releases a pawl 37 that holds the ratchet-plate 39, to which is attached the supporting-arm 27 of the added weight, the ratchet arrangement ensuring fixity of the apparatus when weighing is taking place. Upon the release of the pawl, the supporting-arm 27 with its weight is then capable of functioning. To remove the additional weight from the pendulum, Fig. 3, the rollers 30 of the arm 27 pass from the concavity 20 upon the guide-rods 18 and raise the guiderods. These rods then lift the added weight 13 and permit of the arm taking the added weight from the pendulum to the inoperative position shown in Fig. 5. The counterbalancing of the added weight is effected by dropping the weight 53 upon the scale-beam 2 through the depression of the support 54. The support is hung from the lever 47 which receives its motion through the rod 46 and arm 45. The arm is journaled upon the operating-shaft 28, and its extremity 43 operates to turn a star-wheel 44 upon the index-finger 5<a> and secures the change of face of the finger. The instruction notice is carried by the arm 56 which is raised or lowered by the lever 47.

Class 146(2) A peg chart comprises a plurality of similar quadrilateral chart sections disposed in side by side abutting relationship, each section having a plurality of pegreceiving through holes 11 and, adjacent one edge, a row of holes which are open to that edge but which are closed by the confronting straight unrelieved edge of the adjacent section. The sections may be moulded from thermoplastic material. In one construction, the sections are mounted in channel and H-section members parallel with but spaced from a wall, so that pegs of uniform cross-section may be pushed through the holes 11 to collect in partitioned receptacles for removal. The pegs may be coloured, and may be cubical or of circular cross-section so as to lie flush with the outer surface of the chart, shaped as in Fig. 8 whereby additional signals, e.g. coloured strips, may be gripped between the board and the projecting portions of the pegs, or formed as in Fig. 9 whereby cord or elastic may be passed through the holes 17. The pegs may be removed by means of a comb-like stripper. In the construction shown in Fig. 4, the chart forms the front wall of a cabinet 31, and the insertion of the pegs is limited by a back plate 34 which is pivoted on parallel links 35. The back plate rests on a cam disc 36, and when the latter is rotated, by means of knob 38, the plate is moved to the position 34a to permit removal of the pegs, which are pushed through the holes and directed by walls 39 to a compartment closed by lid 40, which also gives access to knob 38. Peg storage compartments 41 are also provided.

Abstract: 618,144. Moulding acoustic diaphragms &c. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 25, 1946, Nos. 31755 and 31756. Convention dates, April 10, 1945, and May 28, 1945. [Class 87 (ii)] Two liquid suspensions I, J Fig. 1, of fibrous particles having different characterestics are separated by means of at least one partition H having its end in contact with a suction mould B when initial deposits of the particles of both suspensions are made ; during the further formation of the article a relative displacement of the partition H and mould B is produced whereby an intermingling of the two suspensions is effected in a region between the end of the partition and the mould so as to form a controllably defined zone in which particles from both suspensions are deposited. In Fig. 1 the relative displacement is effected by raising the partition H by means of cams 0 which permits a deposit of intermingled fibres upon an annular region around the edge of the conical part of the mould B. Auxiliary suction chambers provided with regulating valves may be provided under the rim and conical portions of the mould to control the relative suction applied to these portions. In an alternative arrangement shown in Fig. 9, the cylinder H remains stationary while the mould B is movably supported by springs U and adjustment screws W. As suction is applied, the mould B moves progressively away from the cylinder H until it reaches a final position depending upon the adjustable flexibility of the springs U.
