Title: Improvements in biscuit cutting and like machinery
IPC: A21C15/04
Filed: 1948-12-01
Abstract: 648,138. Biscuit-cutting machines. VICARS, Ltd., T. & T., and WILDE, A. E. Dec. 1, 1948, No. 31111. [Class 87 (ii)] A biscuit cutter adapted to be attached to the reciprocating head of a machine, comprises a cutter block, cutting shells attached thereto, outside and inside ejectors co-operating with the shells, and spring means consisting of one or more leaf springs adapted to activate the ejectors. The cutter block, Fig. 1, comprises two portions 10, 16, clamped together by means of swivelling members 17. The lower portion 16 carries the cutting shells 19, whilst the upper portion is secured by bolts 14 to the reciprocating machine head 12. A laminated spring 24 slidably adjustable in the block 10 by means of a worm and wheel mechanism 28, 30 to regulate the spring force, bears upon an ejector plate 20 through rollers 33, and bridge portions 34 integral with or attached to the plate 20. Fixed to the plate 20 by means of studs 21a and 23 passing through clearance holes in the portion 16 are the internal ejecting plungers 21 and the external ejector 22. In operation, the head 12 during its downward motion carries with it the cutters 19. By having stop means 39 or 40, Figs. 1, 3, extending below the bottom face of the ejector 22 by an amount substantially equal to the thickness of the dough 41, the ejectors 21, 22 will be arrested when the stops contact the dough support 42. The head 12 and cutters 19 will however continue their downward movement to blank out the dough shapes, and the spring 24 will be energized. On raising the head and cutters the spring 24 will cause the ejectors to remain stationary upon the dough until they are retracted by the head, thus separating the blanks and the superfluous dough from the cutters 19. A modification, shown in Fig. 3, has several leaf springs 35 attached by their ends to adjustable links 36 to the upper part 10a of the block 10. The lower mid-points of the springs bear on rollers 37 which are rotatably secured in pedestals 38 in the plate 20. A suitable spring tension may be obtained by manipulation of the handle 29 or of the links 36.

Abstract: 815,628. Calendars. PEARCE, H. R. Oct. 2, 1957 [Oct. 12, 1956], No. 31220/56. Class 106 (4). A calendar, having a date sheet 12, is provided with an endless band 16, divided transversely into articulated sections 16x and having thereon areas 17 for indicating the date numbers in succession as the band 16 is advanced in steps each corresponding to the width of a section under push-button control. The sheet 12 is shifted laterally by a knob thereon to expose the date numbers appropriate to the month through a window in a mask, marked with day names and having a further window to expose the month name with the number of days thereof. This month information is carried by an endless web 45, Fig. 5, passed round pins 46 and a friction wheel 47, rotatable by means of a knurled wheel 48. The band 16 is guided by a fixed member 20 and a slidable member 23, Fig. 6, the latter being urged to the left by a spring 33, Fig. 4, wound on a pin 34. One end 33 of the spring is anchored to a fixed tongue 35 and the other end 32 passes through holes in a lug of the member 23 and in a lug at one corner of a triangular plate 36 rockably mounted on the pin 34 and connected at its third corner to the cranked end of a push-rod 38. By depressing the rod 38, the member 23 is moved to the right against the action of the spring 33 and a spaced extension 25 engages in the acute angle between two sections of the band 16 and advances it by one section. In. the embodiment shown, the date sheet 12 is transparent apart from the date numbers and the band 16 opaque with coloured circles or squares 17, Fig. 10, arranged in echelon, to frame the date numbers in succession and coloured rectangles 18 to indicate the corresponding day name. In a modification, the sheet 12 is opaque with transparent numerals and the band 16 is coloured to blend with the colour of the sheet 12, so that only the particular date being indicated by a contrasting coloured circle 17 will be visible.

Title: Improvements in braiding machines for making lace
IPC: D04C3/38
Filed: 1921-11-23
Abstract: 172,019. Gerber, E., (Assignee of Seeberger & Co., 0.). Nov. 23, 1920, [Convention date]. Braiding-machines.-Machines for making lace by braiding are provided with intermittently rotated bobbin-driving discs m which are connected to or disconnected from continuously rotating gear-wheels a by the action of the pattern-forming apparatus. Sliding rods c surrounded by coil springs d are mounted in the upper extension of each wheel a and pass through transverse slots g<1> of blocks g mounted in a radially slidable manner in the wheel hubs. The blocks g, the outer ends of which are bevelled as shown in Fig. 5, are held in position shown in Fig. 3 against springs i by the engagement of pins f on the rods c with recesses g<2>. The bobbin-driving discs m are formed with notches x and surfaces n for respectively driving and guiding the bobbins o and are disposed with the upper surfaces flush with the top plate l. Pins v vertically slidable in sleeves u and carrying rings w are acted on by the pattern mechanism to raise or lower the corresponding rods c into or out of engagement with lugs q on the undersides of the bobbin-driving discs m. When a rod c is raised its pin f travels up the recess g<2> and when it is level with an horizontal groove h the part g is released and is moved radially outwards under the action of the spring i, thereby locking the pin c in the raised position. When the bobbindriving disc m has been rotated by the wheel a through nearly half a revolution, the part g strikes a nib k on an adjacent wheel and is forced back against the spring i. This releases the pin c, which drops under the action of its spring d and locks the part g in the position shown in Fig. 3. The moving disc m is brought to rest by the action of the spring s, a nib on which snaps into a recess r on the flange p.

Filed: 1945-11-23
Abstract: 604,071. Slicing mechanisms. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 23, 1945, No. 31619. [Class 5(i)] For slicing-machines having parallel spaced knives to which the articles are fed, knife guides are mounted on successive coils of a compression spring so that the spacing of the guides can be varied by expanding or compressing the spring. In Fig. 1 is snown a bread slicing-machine of the endless band type in which loaves 11 are fed along a supporting platform 12 by a conveyer with pushers 13 pivotally mounted on a chain 14 to feeding devices 16, described in Specification 537,139. The flights 17 of the feeding devices 16 push the loaves through the slicing mechanism which is a series of endless saw-toothed bands 21 spaced on rotatable drums 22. The bands are crossed and partially turned adjacent the cutting position and pass through slotted projections 27 of annular knife guides 26 on cylindrical supports 28 attached to the main framework 23 and mounted above and below the loaves. To accommodate loaves of different heights the upper support 28 is slidably mounted in a slot 31 and has attached to its flange 29 a screwed rod 34 which carries a worm wheel 36 engaging with a worm 37 on the shaft of which is a handle 38 by turning which the support 28 is caused to ride in the slot. The support 28 has a central bore 41 and three parallel bores 42 equally spaced round the central bore and accommodating compression springs 43. Each bore 42 is connected to the periphery of the support 28 by a longitudinal slot 44, in each of which is arranged a series of connecting shoes 46 connected to successive coils of the corresponding springs, each shoe being free to move along its slot and provided with a projecting pin 47 passing into the adjacent guide 26 to position it. on the support 28. Thus each guide is connected to each of the three springs. Flanges 48 secured to the springs at the ends of the support 28 have three radial slots for the passage of spiders 49 in threaded engagement with opposite handed threaded end portions 51 of an adjusting- shaft 52 in the central bore 41. Thus by rotating the shaft 52 the spacing of the knives can be varied. To adjust the spacing of the two sets of guides simultaneously the shafts 52 are connected through worm and bevel gearing to a handle 64. Clamping keys between the coils of the springs may be provided to clamp the spring in any adjusted position.

Filed: 1923-12-18
Abstract: 208,565. Rotmistrow, V. Dec. 18, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Couplings, automatic; combined buffer and draw-gear.-In a central buffer coupling having a coupling member pivoted upon the draw-bar head and controlled by mechanism adapted to be operated by the impact of the buffer, the coupling member has a pincer-like action for which the offset free end of the member makes an angle with the shank greater than 90‹. The draw-bar t terminates in a head a provided, on one side, with a coupling member or claw b pivoted between jaws d, and on the other side with a guide member 7; an ordinary draw hook 8 is provided on the top of the head. A rod c lies parallel to the draw-bar and is connected by lever arms p to a transverse rod o operated from the side of the vehicle; another transverse rod y is connected by a lever arm to a sleeve on the rod c, the movement of the rod y sliding the rod c longitudinally. At the end of the rod c is a projection k of the thickness of the rod, and a stop l. In the uncoupled position the end of the bar c projects beyond the draw-bar head and the stop l abuts the hinged end of the claw member to maintain it open, the projection k lying horizontally between the hinged end of the claw and the draw-bar. On collision of the vehicles, the respective bars c are pushed back, forcing the projection k between the head a and the hinged end of the claw to close, and lock, the claw against the opposing draw-bar head. Uncoupling is effected by rotating the rod c by means of the transverse rod o. The combined buffing and draw-springs are of the flat spiral type which encircle the draw-bar, the centre of the spring being secured by a pin to the draw-bar whilst the outer ends of the springs are secured to casings fixed to the underframing.

Title: Cathode-ray apparatus
Inventor: GERMESHAUSEN KENNETH J
IPC: H01J29/72
Filed: 1957-10-11
Abstract: 821,394. Cathode-ray tubes. EDGERTON, GERMESHAUSEN & GRIER Inc. Oct. 11, 1957, No. 31860/57. Class 39(1). A cathode-ray tube for oscillographic recording of milli-microsecond transients includes a travelling- wave deflection system comprising a pair of single layer, oval-turn, helical windings arranged one on either side of the electron beam path, with their axes extending in the same general direction as this path. Disposed within and along the axis of each winding for its full length but insulated therefrom is a conductive strip operated at earth potential. Thus the windings are substantially independent of each other and may be parallel or divergent or may have curved axes. The dimensions of the windings which are preferably formed of flat conductive ribbon, may be varied to adjust the transmission-line impedance of the windings and strips of dielectric material may be inserted to vary the transit time of the signal deflection current along the helix which should be equal to the transit time of the electrons along the length of the deflection system. As shown, the magnetic focusing coils 17 are located centrally around the deflection windings 15a, 15b, both being approximately midway between the electron crossover, formed by an immersion lens system consisting of the cathode 1, grid 3 and anode 7, and the screen since the minimum crossover diameter is substantially equal to the minimum usable spot size on the screen. This arrangement is said to provide an optimum relationship between sensibility writing speed and scan. The transverse dimension of the deflecting field is preferable less than one tenth of the transverse dimension of the focusing means in the region thereof. The time scan is effected by conventional deflection plates 30 provided with rounded ends 32 to eliminate astigmatic effects. A plate 11 having a narrow rectangular opening 13 is disposed within the steel tube 14 to reduce the electron beam thickness in the direction of signal deflection. A second anode 4 in the form of a cylinder is provided adjacent the anode 7 to decelerate the electron beam beyond the cross over point to permit the presence of lower beam velocitiies in the deflection region. Post deflection acceleration is provided by a highresistance spiral disposed within the insulating cylinder 24, which supports the phosphor screen 21 and which may be surrounded by a final anode 36. Suitable electrode potentials and dimensions are given.
