STEERING GEAR.—Belleaud.—No. 1G,048, dated (under Convention) 13th July, 1906.---This invention relates to transmission mechanism of the kind in

which power is transmitted nrom one shaft to another, the arrangement being such that, whilst movement is obtained from one shaft to the other, a return drive from the latter to the former is prevented. Fig. 1 shows the apparatus in plan, the upper part being supposed to have been removed. Fig. 2 shows the same in vertical section on the line IA—A) of Fig. 1. The driving shaft, or steering rod (d), to which the operating or steering wheel is secured, enters the casing (a) by passing through the cover (b) its inner end is connected to a lever arm, or driver (c). provided with a lug, or projection (t), and a pin (g), which enter, respectively, into a recess (h) in a connection, or link (i), and into a hole in an eccentric, or ring The part (in is secured to a crank (k1 forming the head of the driven shaft (1). This crank passes through the centre of the eccentric (m) of the ring (j), which eccentric is mounted on three parallel crank pieces (a) so as to enable it to have a satellite movement round the vertical axis of the apparatus, when it is driven by the shaft through the parts (e, and the ring (j) in which it is mounted.

This ring rests at its circumference on a flange (a) formed in one with the casing (a). This arrangement enables the shaft (I) to be driven by means of the shaft (d) without any loss of power and with a continuous and unlimited movement, while a return .drive front the shaft (1) to the shaft (4 cannot take place, owing to the eccentric parts being caused to lock in the casing (a). The eccentric parts can be recessed along their circumference, or grooved for thle, purpose of reducing friction, if desired. It will be seen that this apparatus fulfils the desired conditions of efficiency and simplicity and is not cumbersome or unwieldy. SIGHT FEED LUBRICATOR.—Electrical and Ordnance Accessories Co., Ltd. and Another.—No. 26,656, dated 3rd December, 1607.--The object of this invention is to provide a locking device to prevent the valves of the lubricator from moving from their adjusted positions by vibration or the like. In the figures, which are, respectively, a part vertical section and a plan, the casing (1) contains a pair of laterally acting bolts (c) forced outwards by a spring (d) interposed between the bolts whose outward move meats are limits by fixed stop pins (ell which engage within slots (c2). The spindles (e) of the valves have milled adjusting heads (el) and they are provided around their periphery with teeth (12) in which the bolts engage, the spring (d) holding the valve spindles stationary. The bolts (c1 are formed with knife ends which are bevelled on each side so as to allow of readily wiping over the teeth when the valve is adjusted by hand. As another form of the invention, when three, or more, feed-regulating valves are arranged in a curved or circular series, the frame of the lubricator, or a suitable fixed attachment thereto, may be fitted with a radially-arranged series of spring bolts or spring catches, one to each valve. Each catch is adapted to snap into teeth and thus engage with one of the spindles (e).

ELECTRICALLY HEATED VIII.C A NISER.—Weich and A nother .--No. 21,332, dated September 26th, 1907.—The

vulcanising apparatus is arranged to :Ionlain a liquid, and conductors which are heated by the passage of an electric current are wholly or partially immersed in the liquid instead of being embedded in cement in the usual manner. The liquid rapidly becomes heated, and, if it be water, may be allowed to become converted into steam. With ordinary voltages such as are employed on lighting circuits ordinary water may be used. Electrical heating coils may be applied in place of, or in addition to, the usual burner such as is employed, for example, in the "Harvey Frost" vulcaniser. In Figs. 1 and 2, which are, respectively, a plan and elevation, E is a vulcanising mould intended to be f S :ened upon a tyro ID): El, El are heating flues which pass through the mould and form passages through which the products of combustion from a burner (E) pass to generate steam from water contained in the mould : C2 is an electric conductor within the mould, the ends of which are brought to insulated terminals (C3). The conductor itself is

wound round and supported by flues (Et) and is insulated therefrom by beads (GI. The vulcaniser can thus be electrically heated either in addition to, or instead of, being heated by the burner (F), shown in Fig. 2. Switches in conjunction a variable resistance can be provided to regulate the current.
