Title: Improvements relating to vehicle wind screen wipers
IPC: B60S1/14
Filed: 1936-05-26
Abstract: 475,873. Windscreen-cleaners. LUCAS, Ltd., J., and HUYTON, A. May 26, 1936, No. 14834. [Class 138 (i)] The invention relates to means for enabling a windscreen-wiper arm to be moved to an unobstructive position when not in use. A wiper arm a, Fig. 1, is mounted on an oscillating spindle c which is also capable of sliding against a spring e pressing against a collar and a sleeve g. Outward movement of the sleeve is prevented by a pin V. Axial movement can be given to the spindle by a finger piece h. A crank i is mounted on the sleeve g and operated by a connecting-rod j similarly driven. Another sleeve k is secured on the spindle c and carries a coupling piece l. Motion is transmitted from the crank i to the member l by a pin m engaging a gap n, Fig. 2, in the coupling. Serrations o, Fig. 3, may be provided on the coupling l. The pin m may be also serrated to engage the surface when the spindle c is retracted and the pin disengaged. The surfaces may however be smooth. When an electric motor is used a pair of contacts p, Fig. 2, may be employed, one mounted on a spring q pivoted to the bearing d and the other by a fixed part r on the bearing. The coupling l engages a recess s to move the member a against a spring t.

Abstract: 184,608. Upton, S. May 28, 1921. Wheels.-A hand-wheel is built-up of spokes 1 about which is cast a hollow boss 12 of aluminium the outer ends of the spokes being united to a ring 15 of hollow-tubing preferably by welding. When casting the boss a steel mould 3, divided at 4, is mounted on a table 2, and the inner-end of the spokes 1 which have serrations or spiked portions 14, are gripped between grooves in the mould halves, so that the spokes are inclined to the table, by tightening bolts 11. A mandrel, with a taper 9, is fitted in a bush 7 in the mould 3 so that the end 8 projects below the table. Molten aluminium, or the like, is then poured into the mould and forms the boss on solidification. The wheel is covered with celluloid or like material and the mandrel may have a rib on the portion 9 for producing a key-way in the boss.

Title: Improvements in machines for the manufacture of paper tubes
IPC: B31C1/00
Filed: 1923-06-08
Abstract: 217,043. Soc. La Construction, and Nizet, E. June 8, 1923. Paper tubes.-In machines for making cylindrical paper tubes, such as are used in spinning mills for making reels and bobbins, the mandrel operating the windings is given, between two successive rotative or winding movements, a to- and-fro movement enabling the mandrel to take the paper at the place of feeding, thus dispensing with the use of a travelling clip. The mandrel 2 is mounted on a carriage 4 reciprocated from a driven shaft 10 through gearing 1, 1<1>, and a crank 7. The gear wheel 1 has teeth on a portion only of its circumference. During the winding of the paper a plain part 12 co-operates with a plate 13. During the traverse of the carriage 4 the mandrel remains stationary, being driven by an operating pinion similar to the gear wheel 1, having teeth on a portion only of its circumference.

Abstract: 116,213. Bell, W. T., and Perry, F. B. Oct. 17, 1917. Centrifugal governors.-A shaft governor comprises a casing 4 attached to a sleeve loose on the governor shaft. The weights 13 are pivoted at 12 to the casing and at 11 to links 14 pivoted to brackets carried by arms attached to the shaft. When the weights move outwards, the casing and sleeve are turned on the shaft and, by a pin &c. connexion, turn an eccentric sheave which controls the cutoff of the engine. The movement of the weights is resisted by springs, which, at their inner ends, engage the weights, and at their outer ends engage sleeves 16 carried by pins 18. The speed can be adjusted during running by moving wedge members inside the shaft bv means of a hand-wheel and spindle, the wedges en. gaging slots 19 in the pins 18 and thus adjusting the sleeves 16 and springs.

[Class 117] In a separator having a chute provided with slats or the equivalent in stepped formation over which the material passes, air being passed between the slats to draw awav dust at the underside of the material, an imperforate surface is provided for the passage of the material before it reaches the slats. In the form shown, the material leaving the hopper 10 passes over the plain surface 20 before reaching the slats 15 between which air currents pass and convey the dust along the duct 24 to the cyclone separator 25 above which is a chamber 29 containing a filter cloth 30, the clean air escaping to the atmosphere at 34. Above the slats is a series of adjustable hinged flaps 21A enabling the air currents to be varied and a series of freely hanging flaps 21B'to effect even distribution of the material, but these flaps are omitted if a closed air circuit is employed, in which case the duct 35 replaces the outlet 34. The slats 15 may be covered with rubber. In a modification. the chute containing the slats 15 is given reciprocating motion and is joined to the duct 24 by a flexible connection.
