Title: Improvements connected with the bobbin feed mechanism of automatic bobbin winding machines
IPC: B65H67/06
Filed: 1948-12-18
Abstract: 663,200. Bobbin winding machines. ZBROJOVKA BRNO, NARODNI PODNIK. Dec. 18, 1948 [Dec. 18, 1947], No. 32774/48. Class 120(ii) Bobbin feed mechanism for an automatic bobbin winding machine includes separating means carried by a bobbin container movable towards and away from the bobbin carrier of the winding machine, which separating means is adapted to abut a fixed stop or part of the machine frame when the container is moved to a position adjacent to the bobbin carrier and, on abutment, is actuated to separate an end of the lowermost bobbin in the container from the next adjacent bobbin therein. As shown, empty bobbins 4, 4<SP>1</SP>, 4<SP>2</SP> 4<SP>3</SP> are stacked in a container consisting of channel-shaped members 2, 3 fixed by a member 1 to a swinging lever. The ends of the lowest bobbin 4, which supports those above, rest on spring flaps 9, 16, Figs. 2, 3, and a sliding flap 18 covers one end of the bobbin. The bobbin carrier comprises supporting heads 24, 25 mounted respectively in members 27, 26 carried by a shaft 35. After a bobbin has been wound, the bobbin carrier rotates through 180 degrees about shaft 35; the wound bobbin is thereby brought to the. release position beneath the container, and an empty bobbin takes its place in the winding position. A lever 31 pivoted at 33 is moved by a cam in the direction A to cause a lever 29 pivoted thereto to engage an abutment on member 27 and move against spring pressure so as to release the wound bobbin from the grip of heads 24, 25. The container meanwhile swings down to bring the lowest bobbin 4 opposite heads 24, 25; as it does so a lever 7, Fig. 3, pivoted to the container at 6, is rotated by engagement of a foot 22 with a fixed stop 23 to cause a tongue 8 on lever 7 to separate bobbin 4 and raise and support the rest of the stack; also, slide 18 is raised by engagement of a tongue 19 with members 26. An abutment 11 on the container now engages and depresses the end of lever 29, which is spring mounted on lever 31, to release member 27 and allow the heads 24, 25 to grip bobbin 4. As the container rises again, flaps 9, 16 open to allow bobbin 4' to remain in the carrier, tongues 9<SP>1</SP>, 16<SP>1</SP> preventing the remainder of the stack from falling out of the magazine.. Support 1 may be mounted for rectilinear reciprocating, instead of swinging motion.

Filed: 1938-11-12
Abstract: 521,056. Moulding typewriter keys &c. WINDSOR, R. H. Nov. 12, 1938, No. 32945. [Class 87 (ii)] In making parti-coloured articles such as keys for typewriters, calculating machines &c., or dials for automatic telephones, having figures, characters, or designs in one colour on a background of a different colour, a preliminary moulding is made in one colour of the figure &c. which is to constitute the inlay, and subsequently a material of a different colour is moulded around the preliminary moulding to form the background. In making keys for typewriters, the characters are formed by injecting thermoplastic material, such as cellulose acetate, into a two-part mould to form a set of characters 20, Fig. 1, connected to branches 21 leading to a solidified stalk 22. The mould has ejecting pins and projections for forming recesses 26, Fig. 9, in the under side of the characters and for producing apertures 24, Fig. 5, in those parts of characters which enclose a space, e.g., as in the figure " 4." The characters are detached from the branches and stalks and are held by projections in a second mould engaging in the recesses 26. Plastic material 30, 25, Fig. 9, is then injected around the characters to form the background. The branches and stalks of the second moulding operation are then removed from the finished keys. A dial for an automatic telephone is made by moulding the characters 42, Fig. 11, upstanding from a ring 40 having a rearwardly projecting solidified stalk. The stalk is removed, and the ring is supported by projections in a second mould into which thermoplastic material of a different colour is injected to form the body of the dial, the supporting projections producing recesses on the back of the dial.

Filed: 1964-08-13
Abstract: 1,052,098. Pumps operating by electromagnetic interaction switch fluids. G. N. J. MEAD. Aug. 13, 1964 [Sept. 4. 1963]. No. 32954/64. Heading H2A. An electromagnetic interaction pump has a tubular duct 12, of stainless steel lined with zirconia, surrounded by a number of electromagnets comprising winding 18 and yoke 20, each adjacent electromagnet producing an opposing longitudinal field in the duct. The electrodes comprise an electrically conductive strip 22 in the duct wall and a central rod 24 and these are joined by an insulated longitudinal spiral baffle 26 which defines axial passages for the fluid flow. Each baffle member is about the same length as an electromagnet and overlaps the co-operating electromagnet by half its length. Adjacent baffle members are wound in the opposite direction so that the currents flowing are alternately clockwise and counter-clockwise, and thereby pump the fluid along the duct. In n modification two concentric ducts may be used with a clockwise spiral baffle in the outer channel and an anticlockwise spiral in the inner one so that the fluid flow is opposite in the two channels. It is stated that this modification replaces the conventional electromagnets by the fluid ones in the outer channel, Figs. 6 and 7 (not shown). In a further modification, employing a similar duct construction to that shown, only with a single non-conductive spiral baffle extending the whole length of the generator. In this case both the supply electrodes are situated on the outer wall of the duct and are separated by the baffle, the central rod is used as a common electrode. In order to obtain spiral currents in the correct direction the electrodes are alternately masked with insulating material over part of this length.

A machine for cultivating the soil comprises a rotatable wheel 2 provided with a plurality of helicoidally shaped blades 9, at least part of the outline of each blade when viewed in the axial direction of the wheel conforming to an insolute generated by a base circle co-axial with the axis of rotation of the wheel, the wheel being mounted on a frame 1 and rotated so that the linear speed of the blades at ground level is opposite to and greater than the forward speed of the machine so that each blade is disengaged from the soil ahead of it in the direction of movement of the frame. As shown the wheel 2 is driven by a motor 20 which also drives wheels 4 and the machine is steered by means of a wheel 14 and handle 15. The wheel 2 may be raised and lowered manually by means of a rack 18 and pinion 16 and as the wheel 2 is mounted at one side of the machine an adjustable counterweight is provided at the opposite side of the machine. Means may be provided for moistening the surfaces of the blades. In a modification a one way plough is formed by providing two wheels mounted to rotate in opposite directions on a pivoted frame so that the wheels may be raised and lowered at the end of each ploughed furrow. A multi-unit plough is formed by three wheels mounted in a staggered position. The blades on each wheel may be mounted to rotate or tilt to deposit soil laterally. The blades may be arranged so that soil is discharged into the interior of the wheel where it may be sieved and ejected laterally out of the wheel. This embodiment can be used for digging potatoes and the blades are formed as fork-like members. In a further modification wheels are mounted at an angle inclined to the direction of forward movement.

Headings F2E and F2F. In an overrun braking system for trailers having a master cylinder operated by overrun to pressurize trailer brake cylinders, a pressurerelieving expansion chamber formed by a cylinder 9 containing a piston 15 is connected with the line between the master cylinders and the brake cylinders, the piston having an insert 19 adapted to close a bore 13 communicating with feed channel 20, owing to the action of a compression spring 16, until a relatively high pressure, in excess of that required to lock the brakes in forward running, is exceeded, which occurs during backing up of the tractor-trailer unit. When the piston is thus unseated, the whole area of the piston (about 20 times the area of the bore 13) is exposed to the fluid in channel 20, so that piston moves abruptly away from the seating to reduce pressure to about a twentieth of the unseating pressure, i.e. about a tenth of the normal maximum braking pressure, this reduced braking being easily overcome by the tractor so that the driver does not have to dismount or make any adjustments when reversing.
