Abstract: 460,467. Attaching metallic clips to card wire filleting. DRONSFIELD, J. Nov. 15, 1935, No. 31626. [Class 120 (i)] Apparatus for attaching metallic clips to card wire filleting or tops for use with the flats of carding-engines, comprises a bed for the filleting, socketing strips to support and position the metallic clips on either hand, longitudinal angularly moving bars with projections or faces to operate on the clips, and means to enable the bars to be separated or brought together with mechanical advantage gear to actuate the angularly movable bars and cause them to act on and fix the clips to the tops. The wire clothed filleting b is laid on the bed a along each side of which are attached strips a<1> producing sockets to receive and position the pendent sides of clips c. Bars d with flats d<1> and surfaces d<2> are carried in bearings in four lever arms e fixed on shafts e<1> supported in bearings e<2> on the frame F of the machine, so that they may be separated for insertion of the filleting and clips, or closed together and locked by a clamp f with handle f and adjusting screw f<2> for the operation of uniting the clips to the filleting. Pairs of toggles g depend from the bars d being secured thereon by pins d<3> and carry at their lower ends shafts g<1> provided with internal screw-threads to receive a transverse shaft h having right and left-handed screwthreaded portions. Rotation of shaft h<1> by means of a handle h moves the toggles g and rotates the bars d to cause the faces d<2> to press the short limb of each clip c through the filleting. The shaft h passes through a vertical slot i<1> in the central casting i to permit it to rise or fall slightly during movement of the toggles. Stop collars h<2> on either side of and spaced from the casting i, permit slight axial movement of the shaft h. To fix the clip-pressing action of the bars d for a particular thickness of filleting b, an adjustable stop is fitted on the rear end of shaft h. This consists of a barrel with pin l<1> engaging a groove in the shaft h to permit longitudinal movement, and a milled nut l<2> to adjust the position of the barrel l. The bed a is readilv removable for interchange and the casting i is also removable and adjustable vertically by nuts i<4>. A stop bracket m fixed to each shaft e<1> has a foot m<1> to limit the opening movement of bars d and an adjustable stud m<2> to limit its closing movement. The end portions of bed a have a central groove 2 guiding at one end a block 3 which can be fixed in one of several positions by a screwed stud 4. At the other end the groove 2 guides a slidable block 5 held down by a screw stud 6 passing through a bush 5a, and adapted to be fixed in any desired position by a locking stud 7. Blocks 3, 5 each carry a pivoted jaw 8 with teeth to grip the filleting.

Title: Improvements in and relating to vertical broaching machines
IPC: B23D37/04
Filed: 1934-11-07
Abstract: 443,654. Broaching-machines. TOWLER, F. H., Dob Park, near Otley, and TOWLER, J.M., Wells House, Thruscross, Surnmerbridge, both in Yorkshire. Nov. 7, 1934, No. 31932. [Class 83 (iii)] A broaching-machine is fitted with a device for delivering coolant to the broach teeth immediately prior to their entry into the work, the said device being moved into operative position automatically before each operation and returned to inoperative position at the completion of each operation. In Fig. 1, the bush 1 which receives the coolant from a pipe 14, is carried by toothed rods 6 which may be detachably secured at 5 to the draw-head 2. When the draw-head rises on the working stroke, the bush is lifted until it engages under the work 15 so that the teeth of the broach 12 are lubricated immediately before entering the work. The head 2 then continues its movement, the spring connections 5 being disengaged and the bush held in position by the pawls 7 engaging the teeth 6. When the head reaches its upper limit, tappet gear actuates a rod 10 to operate lever mechanism 9, 11 and disengage the pawls, allowing the bush to fall clear of the work, which is then removed. The head then descends and near the bottom of the stroke the broach is released from the head in the usual way and falls on to a lifting-device (not shown), in which position a fresh work piece is placed over the broach. In a modification, Fig. 2, the coolant bush 1 is carried by a member detachably secured to the broach-lifting cylinder 17. The ram is arranged as described in Specification 424,287, [Group XXIX], and when the cylinder is lifted to engage the broach with the drawhead the coolant bush is moved on up to the work 15, which is then carried into engagement with the lower surface of the work plate. In another modification, Fig. 3, the coolant is delivered to the broach by means of pivoted troughs 23. On upward movement of the broach, the work is moved against the work plate 13, which is then lifted to the position shown in Fig. 3 to bring the two troughs up to the broach. When the work is released the troughs swing on the links 25 to an inoperative position. In another modification, Fig. 7, the coolant bush is carried bv a member 1a secured to the piston rod 20 of a cylinder 17. In this case the cylinder 17 may be directly connected to the supply of the broaching-cylinders or to the supply of the broach lifting cylinders (nob shown). After the broach has passed through the work, the downward movement of the bush causes a rod 31 depending from a workreceiving shelf 22 to engage a trip 32 thus tilting the shelf, Fig. 9, and directing the completed work piece on to an inclined shoot 33. A similar work ejector is shown in Fig. 2.

Title: Improvements in or relating to the separation of solid materials of different specific gravities
IPC: B03B4/00
Filed: 1931-11-18
Abstract: 392,578. Separating solid materials. RAW, G., Ravenswood, Low Fell, Co. Durham. Nov. 18, 1931, No. 31994. [Class 117.] In apparatus for separating materials of different specific gravities, as for example in the cleaning of coal or the separation of ores from gangue, of the type in which the materials are simultaneously subjected to a mechanical jigging movement and upward pneumatic pressure so as to cause them to stratify in layers according to density, two or more tables, each provided with a separate air chamber, are mounted as a unit on a single chassis and the air is supplied to the tables in pulsating currents operating in sequence. In another form, the apparatus comprises two or more units among which the air pulsations are distributed in sequence. As a modification of this arrangement, the set of tables on each chassis may be provided with a common air chamber and pulsator device. In the embodiment of the invention shown in Fig. 2, the table unit consists of a chassis b suspended by steel hangers and reciprocated by an eccentric rod e and two forwardly converging tables c of the kind described in Specification 297,757, [Class 117, Sifting &c.]. Each table is provided with a separate air-chamber to which pulsations of air pressure are delivered by means of rotary vanes as described in Specification 305,068, [Class 117, Sifting &c.], the vanes associated with the chambers being 90‹ out of phase. In the case of more than two tables the phase angle is a corresponding fraction of 360‹. Fig. 8 shows an alternative construction in which two machines are employed each comprising a chassis 9 and two or more tables c. In this arrangement, each table may have a separate air chamber and pulsator device 10, or the tables may have a common air chamber and the alternations of pressure take place between the machines. The lateral discharge from the tables on their inner sides is collected by a trough reciprocating with the chassis and is conveyed to a hopper at the end of the machine. Alternatively, discharge passages are provided through or between the air chambers at various points in the length of the machines. Fig, 2 shows a modification of the form of table described in Specification 297,757, [Class 117, Sifting &c.]. The contractions of the sides are on a curved line 1, and the imperforate steps 2 are narrower and steeper at the sides than at the centre of the table. Specifications 274,587 and 336,221, [both in Class 117, Sifting &c.], are also referred to.

Abstract: 861,304. Applying adhesive tape. ADHESIVE TAPES Ltd. Jan. 15, 1959 [Oct. 15, 1957], No. 32142/57. Class 73. A machine for applying and severing adhesive tape 41 from a reel 19 to a polygonal container that is clamped and rotated has a retractable taping arm 10 which is advanced to the container, retracted after the container has rotated a small distance and advanced again towards the end of rotation to apply an overlap of the tape. A carton 40 advances down a gravity conveyer 1, 2, 3, operating stops (e.g. 31) which cause it to be delivered and halted on the section 2. The carton is gripped between plates 8 of clamps 7, which are mounted on the cheeks 13 of a bridge structure astride the conveyer and rotated downwards about a horizontal axis by pneumatic rams C7. The arm 10 is then pivoted downwards about a cross-shaft 11 by rams E3 whilst the arm 16, whereby a taping roller 17 is pivoted to the arm 10, is held by a ram F2 in the position shown in Fig. 2 so that the roller 17 carries the free end of the tape into contact with the carton 40. A pinion 23 engaging a rack 22 moved by a ram H2 starts to revolve the clamps 7 through a drive 25 whilst the conveyer section 2 is hinged clear downwards about its pivot 4 by a ram G2. The rams E3 now retract the arm 10 and the ram F2, the arm 16 whilst the taping continues under tension, as in Fig. 6. The rams E3 again advance the arm 10 on to the face of the carton it first touched. The advance is slow due to a restrictor in the exhaust circuit of the ram and an overlap X is formed. A ram K2 then advances a knife arm 20 to cut the tape as in Fig. 8, leaving a length of it around the roller 17 ready for the next cycle. The arm again retracts, the section 2 hinges up, and the carton is released from the clamps and continues along the conveyer. The pneumatic system, including a cam shaft system by which operation of some of the rams is timed is fully described in the Specification and illustrated in Fig. 9 (not shown).
