controllable and have started or have threatened to run away, and the apparatus by which this purpose is carried into effect comprises a bar capable of lateral movement by means of a spring lever operated by the driver. The bar has pintles passing through holes in jaws on the vehicle and through the trace-hooks fitting into the jaws.

No. 17684.—22nd March, 1904.—JAMES IRVINE, of Napier, Hawke’s Bay, New Zealand, Commission Agent. Improvements in the fastenings of packing-cases and the like.

Claims.—(1.) In means for securing the joints of packing-cases and the like, a plate adapted to be inserted between the faces of the joint, a hole in the plate through which the screw or nail fastening may be driven, and a slot with square sides extending longitudinally from one edge of the hole, and with which a squared portion of the nail or screw is adapted to engage, substantially as specified. (2.) In means for securing the joints of packing-cases and the like, a plate adapted to be inserted between the faces of the joint formed with downwardly projecting barbs on its under-face, a hole in the plate through which the screw or nail fastening may be driven, and a slot with square sides extending longitudinally from each side of the hole, substantially as specified.

No. 17687.—23rd March, 1904.—The Honourable CHARLES ALGERNON PARSONS, of Heaton Works, Newcastle-on-Tyne, Northumberland, England, Engineer. Improvements relating to turbines.

Extract from Specification.—My invention consists in enclosing the idle or inoperative parts of one or more turbine wheels (including in some cases the driving or operative parts when inactive) so that they are screened from the atmosphere and operating fluid, and are rotated in a relatively highly attenuated fluid, whereby the resistance to rotation of the turbine is reduced. My invention further consists in arranging the reversing-blades to

normally rotate idly within the above-mentioned highly attenuated fluid, and providing non-return valves adapted to open when the turbine is reversed and discharge the exhaust steam from the reversing-blades.

No. 17689.—23rd March, 1904.—HENRY BRIGGS, of Hasbrouck Heights, Bergen, New Jersey, United States of America, Mechanical Engineer. Improvements in heel-nailing machines.

Extract from Specification.—A feature of the invention consists in providing a heel-nailing machine with a nail-driving mechanism for driving heel-attaching nails on both sides of the heel during the same interval of time, constructed and arranged to drive the nails on each side of the heel successively. By providing such a mechanism for driving the heel-attaching nails the pressure required to drive the nails through the heel and to clinch the nails against the clinching-plate upon the inside of the shoe is greatly reduced, and at the same time the heel is prevented from being displaced upon the shoe, and is firmly pressed into contact with the sole of the shoe on both sides. Broadly considered, this feature of the invention contemplates driving the nails successively either singly or in groups, and it also contemplates driving nails upon opposite sides of the heel either simultaneously or successively. In one form of the invention specifically described the mechanism for driving the nails is constructed and arranged to successively drive groups of the heel-attaching nails containing nails upon each side of the heel, and in the other form specifically described the nail-driving mechanism is constructed and arranged to drive the nails singly and successively, and to drive nails alternately on opposite sides of the heel. The nails may, however, be driven in others ways without departing from the broad principle of the invention, which consists in driving nails successively, either singly or in groups, on one side of the heel during the interval of time in which nails are being driven successively on the opposite side of the heel. The present invention also consists in providing a heel-nailing machine with means for successively forcing the top lift upon the projecting heel-attaching nails. By applying the top lift in this manner the top lift is forced upon the heads of the nails progressively, instead of being forced upon the heads of all the nails simultaneously, and the pressure required to force the top lift into position is materially reduced. While this feature of the invention, broadly considered, contemplates any means for successively forcing the top lift upon the heel-attaching nails, it is preferably embodied in a construction adapted to impart to the top lift a series of sharp, quick blows, as it has been found that when the top lift is applied in this manner less pressure is required, and less strain is put upon the parts supporting the shoe or upon the wooden last, than when the top lift is applied by means of a gradually increasing pressure. The present invention also consists in the devices and combinations of devices described and claimed, the advantages of which will be obvious to those skilled in the art. The present invention is intended primarily as an improvement on a heel-nailing machine of well-known construction which has gone into extensive use, and which comprises a nail-block, a shoe-supporting jack upon one side of the nail-block, and a series of nail-drivers upon the other side of the nail-block, said parts being constructed and arranged to allow the nail-block to be loaded from the side on which the drivers are located. By the present invention a machine of this type is for the first time provided with means for driving the nails successively either singly or in groups. A feature of the present invention, therefore, consists in providing a heel-nailing machine of this type with means for actuating the drivers to drive the nails successively, which means, broadly considered, may be arranged to drive the nails in any desired order, and is not limited to means arranged to drive nails upon one side of the heel while the nails on the other side are being driven.

No. 17697.—24th March, 1904.—WILLIAM THOMAS THOMPSON, of Mahoe, Taranaki, New Zealand, Farmer. Bit for the prevention of milch cows from sucking themselves.

Claim.—A bit for the prevention of milch cows sucking themselves, comprising, in combination, a piece of hollow tubing as shown in drawing, with three sets of holes punched or drilled in same, mounted upon an ordinary strap headstall. The bit is then placed in the cow’s mouth;
