Patent GB-417994-A (GB)
Title: Improvements in, or relating to, mechanical appliances for removing feathers, stubs and down from fowls, game-birds, ducks, geese or the like
IPC: A22C21/02
Filed: 1933-03-14
Abstract: 417,994. Plucking poultry. BUDD, A. G., and BARTON, H, Station Garage & Motor Works, West Moors, Dorset. March 14, 1933, Nos. 7674/33 and 3669/34. [Class 28 (ii).] A plucking-machine, more particularly for use in removing feathers, stubs and down from poultry and other birds, comprises a member 1 which is reciprocated, e.g. by an eccentric 4 and carries a resilient hooked end 2, between which and an abutment, e.g. a roller 5, the feathers are gripped and extracted by a continuation of the reciprocation. The roller 5 is preferably of rubber or other suitable resilient material, and may be arranged to be rotated by the dragging motion of the member 1, 2. When the member 1, 2 is fully projected towards the bird, a roller 7 supports the member 1, 2 which is spring-loaded, clear of the roller 5 so as to permit the passage of feathers between the member and the roller. The eccentric, in turning, raises the rear end of the member and depresses the end 2, so that the feathers are entrapped. Continued rotation of the eccentric pulls the end 2 towards and on to the crest of the roller 5, this latter effecting the plucking. The eccentric then lifts the end 2 to release the feathers and returns the arm 1, 2 to its starting position. The roller is cleaned by a scraper 10 and a roller 12, whilst the feathers are erected by a sharp edged guard plate 9. In a modification, the abutment comprises a rubber belt which passes over rollers one of which is positively driven. The moving belt assists the plucking and leads away the plucked material to a discharge position for bagging, grading &c. In another modification, Fig. 10, the eccentric operated member 17 is constrained by links 20 anchored at 22, and the hooked member 23 is pressed against the abutment, i.e. the belt 26, by adjustable springs 35. The belt roller 29 is driven from the eccentric shaft by a belt 55. The plucking- means is housed in a casing with a hinged inspection lid, the casing having slotted bearings for the shafts 28, 30 to permit easy dismantling. The front member of the casing carries scrapers for cleaning the belt 26, and the links 22 are enclosed in lidded housings on the sides of the casing. A rubber buffer 34 reduces clatter noise. A number of aligned pluckers each with an independent abutment may be arranged to work simultaneously or in any desired sequence. The front edge of the members 2, 23 may be slotted to form tongues having independent resiliences. A suction fan may be used to induce the feathers to pass into the gripping position, and to convey the plucked feathers to a discharge shoot.

Title: Synchronising and coupling device for motor vehicle gearbox
IPC: F16D23/06
Filed: 1976-02-26
Abstract: 1488475 Positive clutches SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES 26 Feb 1976 [19 March 1975] 07690/76 Heading F2C In a friction synchronized double positive clutch for a change speed gear wherein a clutch ring 5 slides axially on a sleeve 3 fast with a driving shaft 1 to engage radial spokes 8 of the ring between teeth 11 fast with pinions 2, 2<SP>1</SP> and a double coned friction synchronizing ring 12 has baulk surfaces 20 which engage complementary surfaces 8a, 8b on the spokes 8 when the synchronizing ring 12 is rotated relative to the ring 5 by friction drag between coned surfaces 13, 10 on the ring 12 and pinions 2, 2<SP>1</SP> respectively to prevent clutch engagement until synchronism is attained, keys 23 which transmit axial movement to the synchronizing ring 12 are axially slidable in grooves 25 in the sleeve 3 and have transverse recesses 30, 31 respectively engaging with the ring 5 and a spring pressed ball 26. Initial axial movement of the clutch ring 5 acts through the keys 23 to move the synchronizing ring 12 into frictional engagement with one of the pinions 2, 2<SP>1</SP> therafter the baulk surfaces 8a, 8b, 20 prevent further axial movement of the clutch ring 5 until synchronism is attained. At synchronism further axial movement of the clutch ring 5 into engagement with the teeth 11 rocks the keys 23 on the balls 26 and the ring 5 rides out of the recess 30. During initial clutch disengaging movement of the clutch ring 5 the interaction of the spring pressed balls 26 with the inclined sides of the recess 31 causes the keys 23 and synchronizing ring 12 to move back to its central position as shown.

Abstract: 892,215. Cutting sheet material S.T.E.F.A.S.- SOC. R.I. March 11, 1958 [March 16, 1957; Nov. 15, 1957], No. 7715/58. Class 31 (1). [Also in Group XXII] A shears for cutting sheet, e.g. plastic, consists of a frame having a base 15, two substantially vertical walls 16, 18 carrying the disc blades 20, 21 and a horizontal plate 17 joining the rear portions 16b, 18b of the walls 16, 18. The plate 17 is of wedge section and the rear portions 16b, 18b are oppositely curved to facilitate making curved cuts. The disc blades are driven either manually through a lever and ratchet device or by a motor and are connected by gearing. The blades may be mounted in adjustable bushes to vary the distance between the blade axes. The disc blades may be in the form of slot-cutting rollers, forming rollers, e.g. as shown in Fig. 7, or by scalloped or shaped blades to make shaped cuts or cuts in corrugated sheets. The blades may be heated by internal resistance heaters 58, Fig. 8, to which current is fed by brushes 59. One disc may be eccentrically mounted to enable blind cuts to be made. The shears may have an arm 43, Fig. 11, carrying a guide 53 or a gauging stop and a rotatable work-holder 45 for cutting circles. The gearing of the shears may be used to provide a reciprocating motion to the arm 43 or a steady transverse motion to make wavy and helical cuts respectively. Straightening rolls to straighten the severed strip may be mounted on the shear frame.

IPC: G01P5/00
Filed: 1953-03-20
Abstract: 737,816. Magnetic compasses; clinometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 19, 1954 [March 20, 1953], No. 7722/53. Class 97 (2). [Also in Group XXIX] An indicator for measuring the speed and direction of a fluid current comprises a member adapted to stream in the current, carrying means susceptible for a predetermined period to gravity and the earth's magnetic field, the means being fixed relative to the member when the period has elapsed to enable it to indicate the direction and inferentially the speed of the current during the period. The indicators 71, 72 (Fig. 6), for measuring submarine currents, comprise openended cones which are attached by lugs 12 to the rope 68 connecting an anchor 69 and a buoy 67. In one form of indicator, Fig. 1, a jar 18 of " Pyrex " (Registered Trade Mark), the top 17 of which is attached to a bulkhead 16 of the cone, is filled half with hot jelly crystal solution 19 on which floats a magnetic compass and half with petrol 22. Whilst the jelly is molten the compass card is movable according to the earth's magnetic field and gravity so that when the jelly has solidified and the indicator has been recovered the direction and speed of the current can be found from the compass card's position and indication. Another form of current indicator similar to that above is described with reference to Fig. 2 (not shown). A further form of indicator, Figs. 4 and 5, suitable for use at great depth has a solid nose 36 to which is pivoted an arm 39 carrying a graduated metal strip 46. A hollow transparent cylinder 48 pivoted to the arm 39, carries a spring-loaded device 58, 62, 60, 61, 66 for clamping both the cylinder 48 and a compass card 55 within the cylinder. The clamping device is held in the non-operative position for a predetermined period by a soluble pellet 63, e.g. an aniseed ball, and after the pellet has dissolved the direction and speed of the current are found from the clamped positions of the compass card and of the cylinder 48 on the strip 46. For deep water work the rope 68 carrying the indicator may be attached to the anchor by a releasable means, e.g. " a sugar-bag and ring " fixing.
