Patent GB-386174-A (GB)
Title: Improvements relating to driving mechanisms for loom dobbies
IPC: D03D51/00
Filed: 1932-03-29
Abstract: 386,174. Loom dobbies. SOC. LYONNAISE DES MACHINES TEXTILES, and MILLIAT, L., 14, Rue Elie-Paris, Lyons, France. March 29, 1932, No. 9073. [Class 142 (i).] In order that the last weft tread may be found easily, mechanically-operated means are provided for moving the dobby backwards at a reduced speed, the main shaft then being held stationary. In the form shown in Fig. 2, the dobby is driven reversely by a shaft 28 from a motor 14 through gearing 15 .. 25. The wheel 25 is splined on the shaft 28 and is integral with a toothed wheel 26 carrying a single claw tooth 27 for engaging a similar tooth 32 on the loom crank or other shaft 33. When the gears 25, 26 are moved to the left by means of a rod 31, the shafts 33, 28 are driven together by engagement of the pinion 20 with the wheel 26, the gears 24, 25 being disengaged. A driving clutch 18 operated by a lever 19 allows the loom as a whole or the dobby in reverse to be driven as desired. In the form shown in Fig. 1, the dobby is driven by a chain wheel 5 on a plate 6 loose on a sleeve 2<1> which is fixed to the driving pulley 1 loose on the crank shaft 3. The crank shaft carries a plate 7 provided with a planet wheel 8 in mesh with a pinion on the sleeve 21 and an internal gear on the plate 6. Normally, the plates 6, 7 are locked by a spring-pressed pin 9 carried by the plate 7 engaging in a hole 10 in the plate 6. When the loom is stopped, the dobby may be driven backwards by withdrawing the pin 9 by a knob 12 and moving the belt from the loose pulley 4 on to the driving pulley 1. The shaft 3 being held by the brake prevents rotation of the plate 7 carrying the planet wheel, so that the chain wheel 5 is driven backwards at reduced speed. The pin 9 is held retracted against the action of its spring by a projection 13. On rotating the knob through a quarter of a turn, the projection is free to move in a slot to allow the pin to re-engage with the plate after an integral number of revolutions of the chain wheel. In a modified arrangement, the crank shaft is driven by a pulley fast on that shaft, while the loose pulley carries a sleeve provided with a pinion in mesh with planet wheels in gear with an internal gear on the chain wheel. The planet wheels are carried by a disc normally loose on the shaft, and run idly. When the dobby is to be driven backwards at reduced speed, a spring-controlled key operated by a lever is moved to lock the disc and disengage the driving shaft from the chain wheel. On the completion of a revolution, the key moves under the influence of its spring into normal position for driving the chain wheel.

[Also in Groups XXII and XXIV] In a copy-grinding, -milling or -planing machine particularly for making turbine blades, the relative feed movement (arrow A in Fig. 2) in the direction of cut is accompanied by a relativeoscillatory or reciprocatory movement (arrow B in Fig. 4) in the direction of traverse of a frequency which is high compared with the rate of feed and is of an amplitude not less than each increment of traverse so that the cuts form a series of overlapping bands without leaving. ridges. The oscillatory movement may be achieved by mounting a rotary cutter 1 or a number of cutters and follower 2 in swash-plate fashion, either on a single shaft 3, Fig. 1, which is urged towards the work 4 and model 5 by a spring or gravity, or on separate driven shafts 16, 17 mounted in a frame 14 pivoted about the main driving shaft 15; to vary the movements of the work and model if they are of different sizes, the table may be as described in Specification 631,248. Alternatively, a reciprocatory motion may be given to the pattern and work table 36, Fig. 4, by a lead screw 37 which is given part turns in one direction alternatively with smaller movements in the opposite direction by oppositely-acting ratchets 40, 41 driven by an oscillating lever 45 and gearing 42, 43 of slightly different ratios. Since the tracer slips sideways on the model, it will surmount abrupt portions more readily than one simply rolling by friction.
