Title: Multiple-screw actuated collet chuck
IPC: B23B31/20
Filed: 1960-10-17
Abstract: 893,512. Making chucks. JACOBS MANUFACTURING CO. Oct. 17, 1960 [Nov. 20, 1959], No. 35478/60. Classes 83 (2) and 83 (3). [Also in Group XXV] A chuck comprises a body 10 having an internal divergent cam surface 12 to receive a collet 14, a pressure member 18 movable axially to engage the collet, and gearing 42 on the body for simultaneously rotating a plurality of screws 36 connecting the member and the body. The collet has hard metal jaws connected by rubber 13. The body 10 is attached by screws 55 to a mounting member 56. The gear 42 meshes with teeth on the heads of the screws 36 and is rotated by a plastic hand wheel 58 to move the member 18 axially and clamp a workpiece in the chuck. Further tightening of the chuck may be produced by rotating one or more of the screws 36 individually by hexagon spanners inserted in sockets in the screw-heads. To assemble the chuck, a ring 75, Fig. 9, is clamped evenly between the member 18 and the body 10 by the screws 36 and the gear 42 is then meshed with the screw-heads. To do this, the heads may have to be turned slightly to ensure correct meshing, and an error is introduced. The ring 75 is therefore removed and the member 18 reclamped to the body with a number of resilient blocks 82 interposed between them. The surface 76 of the member 18 is then ground truly perpendicular to the chuck axis by a wheel 79. To ensure that, whenever the member 18 has been removed to replace a collet, it is replaced in the same position, the threads in the member are all tapped simultaneously. Washers or ball bearings may be placed between the heads of the screws 36 and the body 10 to reduce friction. The member 18 may be made in two parts, the rear part being of soft metal which is machined true before the front part is attached. The screw-threads in the member 18 may be formed in adjustable bushes 90, Fig. 11, which are secured by adhesive when the chuck parts have been correctly assembled.

Title: Improvements in composing sticks or frames for type casting matrices
IPC: B41B11/52
Filed: 1934-12-11
Abstract: 444,348. Type-bar-making machines. SLATTERY, M. J., 30, Bouverie Street, London.-(Ludlow Typograph Co. ; 2032, Clybourn Avenue, Chicago, U.S.A.) Dec. 11, 1934, No. 35571. [Class 100 (iii)] Assembling matrices. -A composing - stick adapted for centralizing short lines of characters on a slug, or for producing slugs bearing lines of different length with the characters at one end in marginal alignment, has an adjustable matrix-clamping block and a slide-bar carrying a positioning- shoulder, which is adapted to be placed against an abutment on the casting-table of the machine, the movement of the slide-bar being proportional to that of the clamping-block. The matrices are clamped between an end wall c, Fig. 1, of the stick and a sliding block b carried by a tubular rod f. The rod f contains a rack h, Fig. 6, having teeth in the form of screwthreads and having one side flattened, so that, by rotation of the rack by means of a knob i, it can be engaged with, and disengaged from, a toothed locking-block l. A rack-bar p, attached to the rod f, gears with a pinion q carried by a slide-bar d, which is provided with a positioning- shoulder d<1>. The pinion q gears with rockteeth r on the side-wall of the stick, so that one-half of the movement of the clamping- block b is imparted to the slide-bar d. The shoulder d<1> is so located that, when it is placed against an abutment on the casting-table and the block b is in position for a line of full length, the matrix line will register with the mouldslot. Any shorter line will be centralized by the proportional movement of the block band the slide d. By means of a compound pinion a different proportional movement can be obtained. The pinion q can be disengaged from the racks and re-engaged in a new position, to give a non-symmetrical position of the line on the slug. Obturator-plates, carried by the rod f and by the stick, serve to close the open ends of the mould-slot.

Title: Improvements in or relating to radiation detectors
IPC: G01J5/42
Filed: 1966-08-10
Abstract: 1,094,499. Radiation detectors. M.J.E. GOLAY. Aug. 10, 1966 [Aug. 11, 1965], No.35714/66. Heading G1A. A pneumatic detector for infrared and microwave radiation comprises a gas filled radiation receiving chamber and a membrane dividing the chamber into two parts and having a radiation absorbing coating covering a portion of its area whilst the remainder thereof is transparent to radiation. The radiation passes through a window 16, Fig. 1, into the chamber which as shown is divided by two membranes 21, 22 having an absorbing centre surrounded by a transmitting annulus so that heat generated in the absorbing medium is conducted primarily to the gas and not the chamber walls. The absorbing coating on 22 has a resistance equal to the impedance of space, and that on 21 is thicker having a quarter of this resistance. The angles that the walls of the chamber make with the axis 40 are chosen to reflect radiation on to the absorbing regions to ensure maximum absorption of radiation. Heating of the gas in the chamber due to absorption of radiation distorts a mirror 31, the position of which is measured by making it form the image a grating 39 on the grating. A photo-cell 37 detects the degree of registration between the grating and its image. A pressure equalizing tube 30 is provided so that the detector is sensitive only to changes in radiation intensity. In a modification, Fig. 2 (not shown) the window 16 is coupled to a radiation pipe.

Title: Tilting welding gun
Inventor: BENDE ALBERT
IPC: B23K11/31
Filed: 1968-07-26
Abstract: 1,225,016. Welding by pressure. BUDD CO. 26 July, 1968 [26 July, 1967], No. 35876/68. Addition to 1,164,507. Heading B3R. A welding gun comprises a first electrode 62 mounted on a yoke 18 pivoted to a support 12 slidable in a fixed bracket 10, a second electrode 58 mounted on the piston of a cylinder 22 carried on the yoke, a cam bar 32 slidably mounted on the yoke and connected to the piston to cause tilting of the yoke in co-operation with rollers 44, 46 on the support 12, a spring between the fixed bracket 10 and the slidable support 12 and a cam surface 80 on the bracket 10 co-operating with a cam follower 78 to bias the slidable support 12 downward relative to the bracket 10, the arrangement being such that the cam follower 78 is freed from the cam surface 80 in the welding position to allow the electrodes to be floatingly supported by the spring. Alternatively instead of the surface 80 and follower 78, a pin on the cam bar engages a block fixed on the bracket 10. The bracket 10 is secured to a wall &c., the support 12 is in the form of a bar slidable between rollers 14, 16 on the bracket and the yoke 18 pivoted at 20 to the bar 12 clamps the cylinder 22 from which extends a piston-rod 26 carrying the electrode 58 and the cam bar 32 slidable between rollers 38, 40 on the yoke and the rollers 44, 46 on the bar 12. The cam bar 32 has a plane surface 36 engaging the rollers 38, 40 and cam surfaces 48, 50, 52 engaging the rollers 44, 46. A balance spring is arranged in the bar 12, its upper end bearing against screw 86 and its lower end against pin 84 secured in the bracket 10. A link 74 has one end pivoted to the lower end of the bar 12 at A, its upper end carrying a roller 78 contacting the surface 80 of the bracket 10, and a link 76 has one end pivoted to the link 74 and the other end pivoted to the cam bar 32 at B. In operation with the gun in the stored position as shown in the Figure, fluid pressure is supplied to the cylinder 22 to move the pistonrod 26 downwardly, this moving the cam bar 32 over the rollers 38, 40, 44, 46 to tilt the yoke into a vertical position. During this pivotal movement roller 78 is caused to move over the surface 80 towards the left in the Figure. Further downward movement of the piston-rod 26 moves the electrode 58 into contact with the work 88 and pivotal movement of the links 74 and 76 moves the rollers 78 clear of the surface 80. The entire apparatus is then resiliently supported by the spring in the bar 12 and continued application of fluid pressure to the cylinder 22 causes the electrodes to equalize on the work. In a modification a cam block mounted on the top of the bracket 10 exerts a downward force on a pin carried on the cam bar. The pin disengages from the cam on movement of the piston into the welding position.

Abstract: 864,934. Sliding clasp fasteners. HANSEN, H. Nov. 20, 1957 [Dec. 3, 1956], No. 36224/57. Class 44. An apparatus foi holding and feeding a tape 3 while attaching coupling links thereto in the process of making a sliding clasp fastener comprises two conveying members 5, 6 arranged for synchronous movement means, i.e. guide bars 1, 2 and rollers 7 ... 12 for guiding the members 5, 6 ir face to face relation ship through ar elongated guide path, means i.e lower, upper anc lateral guide blocks 18, 19 for introduc ing a tape 3 into the interspace of the opposed faces of the conveying members 5, 6 in a position such that a marginal zone of the tape 3 extends laterally beyond the edges of the conveying members, means i.e. arms 13, 14 acting on the bar 2 for urging the conveying members against one another over the whole length of the guide path by a positive holding pressure over a relatively long distance including the distance before the zone where the attachment of the coupling links takes place so as to cause the tape to be held non-displaceably therebetween so that there is no expanding and contracting of the tape, and means constructed to permit the operation of coupling link attaching means in a point intermediate the ends of the guide path. As shown, the invention is applied to an apparatus for producing a fastener in which coupling links are in the form of a coil attached to a tape 3 by sewing. One wing 15 of the tape is arranged to extend laterally from the bands 5, 6, while the other wing 16 is bent backwards. The block 18 is attached to spring-loaded slidable pins 23, 24 by means of which the block 18 may be withdrawn to permit the tape to be introduced. As the tape is carried forward by the bands, the wing 16 strikes a plough member 27 which bends the wing towards the bar 2. In this position, the tape passes below a stitch plate 28 so that the wing 16 is located between the upper side of the guide bar and the underside of the stitch plate. The coupling links are fed through a passage 29 in the plate 28 so that each link is located on top of wing 15 to which it is attached by means of a sewing needle 30 movable through a hole 31 in the stitch plate.. If a trifurcated tape is used, a third wing 16<SP>1</SP> is kept in a downwardly bent position by means similar to that for positioning the wing 16. The feeding of the coupling links takes place through a passage 32 in a block 33 in which a screw-threaded spindle 34 is rotatably mounted to engage the coupling links and feed them at the desired rate. A knife 35 is arranged to cut through the row of coupling links at desired intervals determined by stopping and starting the spindle 34.

Title: Improvements in apparatus for the manufacture of artificial threads
IPC: D01D5/04
Filed: 1929-11-26
Abstract: <PICT:0343965/IV/1> <PICT:0343965/IV/2> The twisting and winding capacity of plant for the manufacture of artificial threads by dry spinning is increased by providing two rows of cap-spinning devices on the same side of the plant and at substantially the same level, together with guards for preventing interference between the threads. As shown in Fig. 1, a spinning cell 4 is provided with a slot 5 partly covered by a hinged flap 6 and having notches 7 through which the threads pass. The threads pass round a feed roller 9 to guides 10, 11, which are alternately short and long so as to lie over the two rows of cap-spinning devices 13, 14.  The cap-spinning devices 13 of the rear row are arranged between and behind those 14 of the front row, and the latter are provided with guards 15, carried by a plate 16, to prevent interference between the balloons formed by the different threads.  The wharls 18 of the cap-spinning devices are mounted on a lifting-bar 19, and are driven by belts 21, each belt driving one wharl in each row.  Each wharl, however, may be driven by a separate belt.  Fig. 3 shows a modified arrangement in which the near row of cap-spinning devices is slightly raised, the corresponding guides 10 being turned up, so that the thread balloons are of the same size.  In this arrangement, each belt 21 drives adjacent wharls in the same row.  The threads may be lubricated, moistened, sized or stretched on their way to the cap-spinning devices.  The increased number of threads which the apparatus can twist or wind may be produced by increasing the number of pumps and jets, or by using the type of jet described in Specification 344,351.
