IPC: B60J1/16
Filed: 1920-02-25
Abstract: 154,497. Gould, F: D. Feb. 25, 1920. Hoods and opening tops.-On each side of a hood for motor-vehicles, &c., two or more sliding windows 9, 10, Fig. 1, supported on parallel tracks 18, 19 of different length, can be independently extended forwardly or retracted to register with a single stationary window 8, leaving an uninterrupted opening. Each sliding window is secured to two hangers which have shoes 20, Fig. 3, having bevelled front and rear edges, the front shoe being longer than the rear one. These shoes slide on the tracks 18, 19, which have recesses 22, 22<a> fitting the shoes and arranged to lower the windows 9, 10 in their extended position and so provide a tight joint with the vehicle body, pins below the shoes on the rear hangers positively guiding the shoes into the recesses. A plate 30, having three vertical flanges forming two runways, guides and separates the lower edges of the windows 9, 10 and forces them into contact with weather strips 26<a> on suitable packing 26 on the doors 2 to make a weather-proof and non-rattling joint. A triangulated frame 27 has an inner member of channel cross-section into which the front of the window 10 fits, forming a perfect joint between the window and the wind-screen 4. Springs 35 fit into depressions 36 in the windows 9, 10 to maintain them in their retracted position.

Title: Improvements relating to torque-transmitting mechanisms
Inventor: WILFORD ERNEST
IPC: F16H61/02
Filed: 1960-02-18
Abstract: 916,796. Change-speed control. BRADFORD DYERS' ASSOCIATION Ltd. April 13, 1961 [Feb. 18, 1960], No. 5798/60. Class 80 (2). [Also in Group XVI] A driving-shaft rotating at a constant speed rotates a driven member at a speed depending upon a variable condition, by means of a pneumatic tyre the effective radius of which is varied to vary the output speed. As applied to a textile machine in which fabric 9 is drawn from a vat by nip rollers 7, 8, a compensating roller 10 is carried by an arm 11 pivotable about 12 to take up slack in the fabric. The arm 11 controls a valve 13 controlling a pneumatic motor 15 having its piston linked to a gear-box 17 pivotally mounted about a shaft 18. A tyre 19 is mounted on a shaft 20 and frictionally engages a driving pulley 21 and is geared to the nip roller 8. If the compensating roller 10 moves upwardly to take-up slack the gear-box is pivoted to lower the tyre which is pressed harder against the pulley to decrease its effective radius and rotate the nip roller 8 faster. An initial adjustment can be effected by altering the axial position of the pulley 21 which is of conical shape. In a modification a valve moved by the compensating roller directly controls the air pressure in the tyre. In another modification in which fabric is wound on the top roller of a pair of nip rollers, the bottom roller of which is directly driven by a pneumatic tyre, the nip rollers are mounted on a rocking frame and bear on the tyre which is compressed as the weight of the fabric increases so that the rollers are driven more slowly. Preferably the surface of the tyre is composed of segments separated by gaps.

Title: Improvements in dough dividing and shaping machines
IPC: A21C5/00
Filed: 1928-02-27
Abstract: 291,333. Srovnal, J. Feb. 27, 1928. Steam-cutting machines delivery; rolling- machines.-Pieces of dough are shaped and curled by the oppositely-moving portions of a bight in an endless belt. The endless band 7, with driven gear-chains attached to its edges, forms a bight at the right-hand side of Fig. 1 and is perforated at intervals to allow the moulded dough to drop through on to a delivery conveyer 111 which in turn delivers, it to a delivery table 58, Fig. 7, with a ratchet step-bystep feed. The dough is placed initially in a container 92, by opening a weight-controlled door 91, and is expelled therefrom by a worm 90 rotated intermittently bv the ratchet mechanism 98 actuated by the linkage 101, 103. A carriage, reciprocated by the crank gear 19, carries a, cutting band knife 38, Figs. 1 and 2, situated between two endless belts 46, 47. These belts are attached to the container at one point so that they unroll from the mouth of the latter as the carriage moves, instead of sliding laterally across the mass of issuing dough. As the carriage completes its movement from left to right, the mechanism shown in Fig. 10 strikes a fixed stop 51 and raises a lever 41 which engages the upper run of the band knife 38 and raises the latter into the acting position so that it removes a slice on the return stroke. At the end of this stroke a second stop 52 lowers the knife to an. inoperative position. The removed slice is carried by the belt 7 into the bight and is subjected to the pressure of a hinged spring plate 110 during the rolling process. A compressed-air flour discharger is mounted behind the band knife to flour the severed pieces of dough.

Title: Improvements in or relating to typewriters used for preparing hectograph sheets or masters for duplicating
IPC: B41J3/24
Filed: 1938-02-28
Abstract: 499,443. Typewriters. AUSTIN MOTOR CO., Ltd., WHITEHOUSE, H. N., and CHARLTON, E. S. Feb. 28, 1938, No. 6195. [Class 100 (iv)] Ink - ribbon mechanism ; paper - supports ; sheet-feeding arrangements.- Hectograph carbonpaper, arranged behind a master sheet which passes under the platen of a typewriter, is fed at a slower rate than the master sheet. The arrangement greatly reduces the amount of carbon-paper employed., since the lines typed thereon may be in contact, and feed need not occur when blank spaces on the master sheet are being fed past the printing line. The carbon-paper and master sheet may be fed in the same or opposite directions, and the carbonpaper may be employed in sheet or roll form. In the arrangement shown in Figs. 2 and 4, the carriage 10 is provided with a platen 17 consisting of a stationary sheath which is spaced from and partly surrounds a roller 12 secured to a sleeve 14 loosely mounted on a shaft 13. The master sheet 43 is fed through a guide 19 and over the platen by means of feed-rollers 20, 41 carried by spindles 21, 39 having pinions 26 which engage a pinion 27 on the shaft 13. A ratchet-wheel 29 on the shaft is operated by a pawl in connection with the usual line-spacing lever. The carbon-paper 42 passes around the roller 12 and is held in contact therewith by a spring-urged roller 44. When a carbon web is employed, it is led from a roll which is mounted on the carriage and a provided at the ends with spring-brakes. The carbon-paper is fed by means of a pawl which co-operates with a ratchet-wheel 34 on the sleeve 14 and is connected to the line-spacing lever. The types strike through a slot 33 in the platen 17 and force the master sheet into contact with the carbon-paper. When the line-spacing lever is operated, the master sheet and carbon sheet are fed at differential speeds and in opposite directions. Specification 466,720 is referred to in the Provisional Specification.

Title: Automatic control system for a textile tenter frame apparatus
IPC: D06C3/02
Filed: 1976-02-17
Abstract: 1499482 Tentering and testing fabrics MEASUREX CORP 17 Feb 1976 [11 April 1975] 06252/76 Heading D1S The yield of fabric 14 from a tenter frame 12 having an overfeed roll 30 for overfeeding fabric on to tenter belts 36 or chains is controlled by controlling the speed of the roll 30 in response to the sensed width, moisture content and specific weight of the fabric at the entrance to the tenter frame. As shown, fabric 14 from a supply roll 16 passes around guide rolls 18, 22, 24 through a tank 20 in which it is moistened and then passes over a suction slot 26 and through a scanning sensor device 28 to the overfeed roll 30 driven by a servomotor 32. The tenter frame is located within an enclosure 34 having a heat controlled dryer section. Each tenter belt 36 carries pins 38 and passes around sprockets 40, 42 of which the sprocket 40 is driven by a controlled servomotor 44. The device 28 measures the fabric specific weight and moisture content and sends signals to a digital processor 46. Edge sensors 48, e.g. of the photoelectric type, measure the fabric entry width and send a signal to the processor 46. Tachometers (not shown) provide signals proportional to the speeds of the roll 30 and the sprockets 40. At the exit of the tenter frame, an edge sensor 50 measures the fabric width and a scanning sensor 52 measures the specific weight. All of the signals are supplied to the processor 46.  The system has two modes of operation, (a) a start-up or stylo change mode, i.e. when a fabric first moves into the tenter frame as it commences to function or when two types of fabric having different characteristics connected together end-to-end enter the tenter frame, Fig. 1, and (b) a steady-state mode, Fig. 2 (not shown). The system may be switched automatically or manually from one mode to the other. In mode (a), the control system works on signal data produced at the frame entry end only, i.e. the signals indicating the entry width, specific weight and moisture content and overfeed speed and tenter sprocket speed are computed to predict the exit dry yield of the fabric. The predicted yield is compared, in a summing section 58, with a preset target yield to produce an error signal supplied by a lead 60 to control the speed of the roll 30. In the mode (b), signals from the sensors 50, 52 provide a value for the actual exit yield of the fabric and this is compared with a target yield value and thereafter modified by a correction factor proportional to variations in predicted dry yield computed from signals representing the specific weight, moisture content and width at the frame entry end. The modified control signal is applied to vary the speed of the roll 30.

Abstract: 834,866. Overload release clutches. GELENKWELLENBAU G.m.b.H. Feb. 27, 1958 [May 3, 1957], No. 6351/58. Class 80 (2). An overload release positive clutch for cable winches, fire escapes, &c. comprises a driving plate 1, Fig. 1, having relatively gently sloped recesses 2 engaged by teeth 3 on an intermediate plate 4 itself provided with more steeply sloped recesses 5 engaged by teeth 6 on a driven clutch plate 7 splined to a driven shaft 9, a spring 8 biasing the teeth and recesses into engagement, overload of the driven shaft first causing the intermediate plate 4 to move axially relatively to the driving plate 1, as shown in Fig. 2, and next causing the driven plate 6 to move axially against the bias of its spring 8 relatively to the intermediate plate 4, Fig. 3, a spring-pressed ball detent 11 then engaging a groove 13 in the driven plate 7 to hold it in its disengaged position so that when the tips of the teeth 6 ride out of the recesses 5, Fig. 4 (not shown), spring 14 is able to draw the intermediate plate 4 back to the position where its teeth 3 fully engage the recesses 2 in the driving plate 1, Fig. 5, the intermediate plate 4 thus being completely free from the driven plate 7. In the preferred construction shown, the spring 14, Figs. 6, 7, is located within the driving plate 1 and the intermediate plate 4, and the driven plate 7 is exteriorly splined to slide axially within a driven sleeve 16 against the bias of its spring 8. The locking balls 11 are received in radial holes in a flange fast with the driven sleeve 16 and are engaged by an axially movable plunger 17. Under normal driving conditions, the parts take up the position shown in Fig. 6. On overload, the driven plate 7 slides within the sleeve 16 relative to the driving and intermediate plates 1, 4, as already described, so that recesses 13 therein receive the locking balls 11 urged outwardly by the spring biased axially slidable plungers 17. The clutch is held disengaged until a control ring 18 is slidden leftwardly to engage the plungers 17 and move them to a position such that the balls 11 will allow the driven plate 7 to be restored to its engaged position by the bias of its spring 8.

Filed: 1971-03-09
Abstract: 1385897 Filling cakes JAHN (HUNTING- DON) LTD and J A HORNBY 17 Feb 1972 [9 March 1971] 6376/71 Heading A2A Filling material is introduced into a baked cake by a plurality of nozzles which are inserted into the cake and inject the material through openings lying in a common plane so that a generally flat layer of filling material is formed within the cake extending across substantially the whole area thereof 'but not breaking through its side wall or walls. As shown, four cakes 11 delivered by a horizontal conveyer 12 are transferred by a pneumatic actuator 14 on to a conveyer 15 which carries them between guides 20, 21, 22 to a gate 23 by which they are aligned and then released to pass to a second gate 25 which arrests them under four injection heads each comprising a hollow casing 28 with hollow needles 29 provided with discharge openings 30, two in each needle, lying in a common plane. An injection head for a 6 inch cake may have, eg, 75 needles. A frame carrying the injection heads is lowered by a pneumatic actuator so that the needles enter the cakes, and pneumatic piston and cylinder devices 35 are operated to force charges of filling material, received from a hopper 32 supplied by a pump 33, into the cakes. An apertured stripper plate through which the needles pass holds down the cakes when the needles are withdrawn. After injection, the gate 25 is opened to allow the cakes to pass to an enrobing machine. The needles may, alternatively, be inserted through the bottoms or sides of the cakes, the cakes may be moved instead of the needles, the cakes may have more than one layer of filling, and the apparatus may be so arranged that the tips of the needles are passed right through the cakes and then retracted slightly before injecting takes place. In the latter arrangement the conveyer 15 is apertured or slatted to receive the ends of the needles and may move intermittently, or the injection heads may move with the conveyer while the needles are in the cakes.
