A Resume' of Recently Published Patent Specifications

-no ATENT No. 383.463, by Movable

Floor (Vehicles), Ltd., and Allan E. Renwick, both of Portfield House, Adelaide Street, Cardiff, describes a moving floor which can discharge its load on either side, it being also possible to discharge half the load at a time. The floor is composed of a flexible belt, which is attached at both ends to rollers, see that it can be wound from one roller on to the other, the belt not being of the endless type.

Beneath the belt the floor is composed of a number of rollers, which can be staggered so as more evenly to distribute the load. The rollers to which the belt isA attached need not extend the whole length of the vehicle, but can be divided into sections for easier manipulation and for discharging only part of the load.

A partition can be arranged between each section, and to prevent such loads as sand, gravel, etc., from injuring the edges of the belt a T or ET-section iron can be placed between the belts, with overhanging parts to protect it.

A Rubber-bushed Bearing for Shackles. A RUBBER-BUSHED bearing, which

is described as being especially suitable for use in the eyes of spring shackles, is shown in patent No. 383,274, by Societe Anonym° des Etabts, Repussean and Cie., 75, Rue Danton, Levallois-Perret, France.

The inner and outer members are of conical form, the rubber lining being suitably shaped, and having a greater substance at the larger diameter of the cone. The two outer cones are held together by a casing, which may be spun over at the edges.

The bearing should prevent end movement, but this does' not appear to 2344

be the main claim. It is not very clear how the outer cones are assembled in the case of the left-hand figure, This patent has become void.

For Renewing Valve Seats. A VERY complete outfit for renewing valve seats is described in patent No. 383,188, by Richard Burston, 30, Dartnell Avenue, Toronto. A bracket

is shown which may be fixed over the valve seat, and centred by means of the pilot on the spindle, which in turn carries the cutter for boring away the metal to allow the new seating to be fitted, also it carries a tap.

After the recess is tapped the new seating can be introduced and screwed firmly in place by means of a collar, which has projecting dogs to engage with corresponding recesses. After the seating is firmly in place the upper part can be milled away by means of a cutter held by the spindle. Another cutter can give to it the necessary conical shape for the reception of the valve. The screwed sleeve can be used to feed the cutting tools, cause the tap to enter, and hold down the dogs on the new seating.

Brake and Gear Levers for Rubber-mounted Engines.

IN their specification, No. 383,488, the Ford Motor Co., Ltd., points out that with engines which are suspended so that their vibrations are not transmitted to the frame, it has been found that such vibrations, being mainly in the nature of rolling, due to the reaction of the engine on its crankshaft, cause unpleasant movements of the hand-brake and change-speed levers. To overcome this appears to be the main object of the invention. The brake lever is particularly dealt with in the specification, where a rectangular upper part is mounted within a sleeve similar in shape in its interior, but wider in one direction, as shown in the sectional view. The inner part reprerents the upper part of the lever, which is gripped by the hand, and which can transmit movement to the surrounding boss, but which permits a certain amount of side play.

The section is on the line 4.4, and a rubber ring will be seen separating the boss from the outer bell.

A Clear-view Windscreen.

WE have often wondered why some of the clear-view windscreens which have been invented have not found more favour.

The latest design is described in patent No. 382,141, by R. W. Livingstone, 27, Thomaston Street, Kirkdale, Liverpool.

Although p r manly intended, and (as illustrated here) designed for use on ships, the specification mentions the fact that it can be applied to road vehicles. The illustration makes the passage of the air so plain that little description is necessary, the arrows indicating its upward course, whilst the clear-view is shown at 12 and 3, the aperture at 12 being adjustable. Air entering at 5 is carried upwards by the main current.
