Title: Improvements in Variable Speed Gearing.
Inventor: DUMARESQ WILLIAM NEWTON
Filed: 1903-01-19
Granted: 1903-11-05
Abstract: 1301. Dumaresq, W. N. Jan. 19. Lathes.-Variable-speed gearing of the type described in Specifications Nos. 2491 and 5694, A.D. 1902, [Abridgment Class Mechanism &c.], is applied to any machine &c. where it is necessary to vary the relative speed of driving and driven shafts. The shafts are geared together by a cord or chain passing over pulleys or drums, one or both of which are built up of pulleys or sprockets mounted on the ends of arms. These sprockets may be mounted on axles so as to be free to rotate in one direction, or may be mounted so that they can be locked to the axles or released as described in Specification No. 23,133, A.D. 1902, [Abridgment Class Mechanism &c.]. The drums or wheels can be expanded or contracted by moving the arms carrying the drums &c. towards or away from a central axis. For this purpose, the arms may be formed with pins to engage a scroll thread in a plate, after the manner of the scroll chuck of a lathe, so that, by revolving the plate relatively to the arms, the arms may be moved outwards or inwards. When only one drum or wheel is adjustable, a jockey pulley &c. is provided for maintaining the tension of the cord or chain. Fig. 1 shows means for effecting automatically the expansion and contraction of the driving and driven drums, the gearing being shown as applied to a lathe. The racks 125 for adjusting the diameters of the driven and driving drums are coupled to a yoke 28 in engagement with a screw 29. A chain-wheel 72 on the screw is geared by a chain 71 with a wheel 70 fixed to a bevel-wheel 67 loosely mounted on the driving-shaft 105. The wheel 67 gears with an idle wheel 69 in gear with a wheel 68 loosely mounted on the shaft 105. Either of the wheels 67, 68 can be fixed to the shaft 105, according to the direction in which the screw 29 is required to turn, by means of a clutch 65. The fork 64 for shifting the clutch is coupled by rods 62 to a lever 56 connected by an arm 58 to a lever 57. A projection 54 on the tool-rest 53 moves one of these levers at each end of the stroke, and thereby shifts over the clutch so as to reverse the direction of rotation of the screw 29. Springs serve to retain the levers 56, 57 in the position to which they are moved. During the movement of the tool-rest between the extreme positions, the drums are adjusted by the screw 29 so as to obtain a continuous variation in the speed of the lathe spindle. The clutch 65, or other parts of the adjusting-mechanism, may be operated by hand.

Title: Improvements in Machines for Combing Wool and other Fibrous Substances.
Inventor: HEY ISHMAEL
Filed: 1903-03-30
Granted: 1904-03-17
Abstract: 7319. Hey, I. March 30. Combing - machines; stop - motions. - Wool and other fibres are pressed into the teeth e, f, Figs. 4 and 6, of the circular combs a, b of Noble's combing-machines, by blades 1, 2, &c., which yield to a hard foreign substance. The blades are loosely mounted on pins fixed in bearings h, which are secured to a lever k pivoted to an arm k<2> fixed to a bracket m on the machine pillar d. A rocking lever p, pivoted at p<2> to the bracket m and having a projection p<3> engaging an opening in the lever k, is normally held against a stop m<1> by a spring g, and depresses the blades into the comb teeth. The upper end of the spring is connected to, and the tension regulated by, a screwed piece t<1>, which is fitted in a lever s, pivoted at s<3> and provided with projections embracing a projection p<5> on the lever p. In case of a hard substance passing under the blades, the blades and lever k are raised sufficiently to carry the spring q across to the other side of the pivots p<2>, s<3>, as shown in Fig. 6, the contraction of the spring then acting to raise the blades. The rotary discs u, u<1>, u<2> are mounted on spindles carried by the lever p, and are driven by band pulleys v<1> arranged close to the pivot p<2>. The correct spacing of the loosely-mounted blades is retained, when the lever k is lifted, by means of two grid-pieces w, w<1> carried by a bearing secured to a lever w<3>, which is fixed by a bolt w<5> to a spring w<4> on the lever k. On rising, the blades enter the spaces in the grids and afterwards lift them, and, on lowering, the grids descend with the blades, until arrested by an adjustable screw y in the lever w<3> coming against a stop m<2>, the blades continuing their descent until clear of the grids. The bolt w<5> may be adjusted to throw a greater pressure on the screw y, which thus helps to counterbalance the parts carried by the lever k. The raised blades are depressed into operative position by pressing the knob t<1> towards the pillar d. The lifting of the bearings h may operate a stop-motion.
