Title: Improvements in Claws for Milking Machines.
Inventor: DAVIES JOHN HENRY
IPC: A01J5/04
Filed: 1918-04-04
Abstract: 124,301. Davies, J. H. April 4, 1918. Cow-milkers.-A claw for a milking-machine is provided with automatically-operated valves to cut off the connexion between the teat cup and the milk and pulsation pipes when the teat cup is not applied to the cow's teat. The milk-pipe 2 and pulsation pipe 3 are arranged in parallel and connected by bridge-pieces 6 carrying the cylindrical vaivs chambers 4, which are arranged in pairs at each side of the pipes 2, 3. A plug 11 is mounted in each chamber 4 and has two passages in it; the one 12 communicates with a branch pipe 14 and registers, when the branch is in its raised position, with a passage 8 leading to the milk pipe 2, and the other passage 13 communicates with a branch pipe 16 and can register with a passage 9 leading to the pulsation pipe 3. The branch pipes 14, 16 are connected by the usual flexible, pipes 15 to the inner and outer chambers of the teat cup respectively. When the cups are attached to the cow is teats the branches 14, 16 are held in the raised position shown in Fig. 7, and communication between the teat cups and the pipes 2, 3 is maintained; but when the cups are not attached to the teats, or when one falls off the teat from any cause, the weight of the cup causes the branches 14, 16 to rotate in an opening 7 in the wall of the chamber 4 sufficiently to move the plug 11 so that the passages 12, 13 no longer register with the passages 8, 9 and communication between the teat cup and the pipes 2, 3 is closed.

Patent GB-565223-A (GB)
Title: Improvements in machines for producing screwthreads or other metal turning or grinding machines
IPC: B23G1/38
Filed: 1943-04-14
Abstract: 565,223. Grinding screw threads. GREEN, A. April 14, 1943, Nos. 5948 and 21546. [Class 60] [Also in Group XXII] In a grinding-machine or lathe for turning or screw-cutting, wherein the work and tool have relative rotation and a correlated relative reciprocation in the direction of the work axis, a disc is driven from the rotary member and has a flexible band attached thereto and to a second member so that the rotary motion of the disc is converted into rectilinear motion which is transmitted to the reciprocating element. As applied to a screw-cutting lathe, the headstock 15 and tailstock for supporting the work 14 are mounted on a slide 12 movable longitudinally relatively to the cutter 11. A shaft 17 on the headstock is rotated by a hand wheel 18 or by power and drives the face-plate 24 through worm gearing 17<1>, shaft 19 and gearing 54. A worm 20 on the shaft 19 drives a transverse shaft 22 carrying a disc 23 to which flexible bands 32, 33 are attached, the free ends of the bands being secured by clamps 36 to a bracket 42 secured to the machine bed so that rotation of the work and the disc 23 will cause the slide 12 to be traversed axially. The disc 23 is secured to the shaft 22 by cones 28, 29 and a hand nut 30 so that the disc may be changed for others of different diameter to vary the pitch of screw being cut, the bracket 42 being vertically adjustable to maintain the free ends of the bands 32, 33 tangential to the disc, or the height of the bands being varied by packing blocks. The band 32 is attached to a member 40 horizontally adjustable on the bracket 42 to tension the bands. One band only may be employed, the slide 12 being returned by a weight or spring, and the longitudinal traverse may be given to the tool slide instead of the work. Disconnection of the drive to the disc 23 by means of the nut 30 will allow the slide 12 to be returned rapidly by hand without rotation of the work. The pitch of thread being cut may also be varied by changing the ratio of the gearing 54, or a reverse drive may be introduced in this train. In a modified construction the axis of the disc 23, Fig. 6, is parallel to the work axis and the ends of the bands 32, 33 are attached to a transverse slide 43 slidable in a guide 51 on the headstock and carrying an inclined cam surface 48 engaging a similar surface 44 secured to the machine bed so that movement of the slide will traverse the slide 12 axially. The pitch of thread being cut may then be varied by changing the inclination of the surfaces 44, 48. The stationary abutment 44 may be perpendicular to the work axis, the inclined surfaces then being between the slides 43, 12, and one inclined surface may be replaced by one or more rollers.

Abstract: 1,036,523. Glove sewing machines. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. Feb. 14, 1963 [Feb, 14, 1962], No. 5992/63. Heading D1G. In a glove sewing machine the work is gripped between a horizontal, intermittently rotated feed wheel 31 and a horizontal presser wheel 58 mounted upon a slidable support 12 spring-biassed towards wheel 31. Jaws 95 for a gripper needle 80 having an eye at one end are disposed above disc 58 and are mounted in a support 90 arranged to move linearly to and away from wheel 31 and to rotate about a vertical axis. A rotary looptaker 70 is mounted co-axially on wheel 58. Needle gripping jaws 85 and an associated holder 107 are disposed above wheel 31 similar to jaws 95 and holder 90. Associated with each wheel is a reciprocating needle bar 150. A presser foot 77 mounted upon support 12 and associated with wheel 58 co-operates with a fixed plate 75 associated with wheel 31. At the commencement of a seam, the needle is held in jaws 95 with its point directed towards the work and its eyed and engaged in the slotted end of a pin 160, Fig. 15 (not shown) associated with the needle bar 150. Holder 90 and bar 150 then move towards the work, when holder 90 stops and jaws 95 open, while bar 150 continues to move for parring needle 80 through the work and into the open jaws 85, which then close. Holder 107 then moves slightly towards the work for forming a vertical loop of needle thread which is then entered and expanded by the rotary looptaker 60 while holder 107 rotates through 180 degrees and moves away from the work. During this movement one arm of the expanded thread loop is engaged by a pivoted hook 271, Fig. 24 (not shown), on one end of a horizontal bar 270 fixed to a vertical shaft 250. Counter-clockwise rotation of the latter actuates hook 271 to draw a measured length of thread within a circular groove formed in a fixed horizontal plate 13. Finally the free arm of the thread loop which is held at bar 150 by a spring-biassed catch 162, is engaged by a hook and is drawn upwardly to set the stitch. The operations are then reversed when the needle is passed through the work into the jaws 95, the loop is taken by the member 70 and is further expanded by pivoted hook 272 on bar 270 which now rotates clockwise, the stitch being finally set by the upward movement of a hook.

Abstract: 1,087,384. Continuous casting. AMSTED INDUSTRIES Inc. Feb. 16, 1966, No. 6837/66. Heading B3F. In apparatus for continuous casting a sealed container 12 enclosing a ladle 16 containing molten metal 22 has a cooled open-ended mould 28 with a graphite sleeve 32 mounted on the container. A pouring tube 26 communicates the mould with the molten metal and in operation molten metal is forced by air pressure from the ladle into the mould. The casting 42 formed in the mould is continuously withdrawn by roller means 44. To ensure a uniform supply of molten metal to the mould in relation to the rate of withdrawal of the casting, control means 58 is provided. This control means is operated in relation to the weight of molten metal in the ladle 16 by sensing means 18 on which the ladle is carried. The variation in weight of the molten metal is arranged to affect the pressure of air supplied to the container, the air pressure being inversely proportional to the weight of molten metal. Electrical circuits are described to indicate means of steplessly varying the air pressure in relation to the uniform supply of metal to the mould.
