W. SHEPHERD, No. 9603, dated 1st _July, 1915.—This specification describes convertible bodies for motor-vehicles. The -foundation or permanent body comprises a well with seats fixed along each side. When it is required to provide a passenger vehicle, backs are secured to each of the seats as shown in the drawings, and these backs support pillars which carry the roof. If desired, the pillars may also carry windows. To provide a box van, vertical side boards are *fixed to the top of the hacks, the side pillars being also retained in use. To provide a dray or lorry, a flat bottom is laid across the seats and secured to the bolts which, in the other arrangements, hold
the -side pillars.
The design appears to be particularly suitable for use in connection with light vans for general purposes. The spaces under the seats could probably be efficiently utilized.
J. L. WALKER. No. 16,494, dated 23.rd November, 1915.— In this silencer the exhaust pipe is slotted near one end and the gases escape from it into a spiral passage formed by two spirally bent plates. They escape from this passage into another longitudinal pipe which is slit for the greater portion ofits length. The spiral plates have beaded edges and are secured between cast-iron end-plates, the beaded edges fitting into spiral grooves. The plates are perforated to allow the free passage of air bs.-tween the convolutions of the spiral passage, thereby effectively cooling the exhaust gases before they Issue to atmosphere. The cooling of the exhaust gases before they issue is stated to be very effective and, moreover, the whole construction is such that the silencer is easily dissembled for cleaning and reassembled.
• 0. P. ROBERTSON, No. 101,949, dated 18th July, 1916.— This invention relates to detachable rims of the type in which a tire-carrying rim is supported on a false rim-attached to the felloe of the wheel, or constituting the rim of a wire wheel. The drawings show a construction suitable for a wooden wheel ; the false rim is secured to it and has at one side an upturned
or outwardly flared flange, and at the other an inwardly turned flange, which lies against the felloe..
The tire-carrying rim has the usual beaded edges, and is formed in addition with an inwardly directed flange adapted to lie beside the inwardly turned flange on the false rim. The outer or tire-carrying rim is of slightly larger diameter than the fixed rim and is supported on it at one side by engagement with the sloping flange, and at the other side by the nuts on the bolts locking it in place. The nuts are each formed with an inwardly projecting sleeve fitting holes in the flange of the detachable rim.
F. STONE and C. TfouNar, No. 71,322, dated 10th December, 1915.—The accompanying drawing shows a new construction of make-and-break device. It consists of a metal disc having a boss formed integrally with it to make contact with the armature. A segmental recess at one side of the disc is occupied by a correspondingly shaped piece of metal, but the two are separated by insulation. Contact with the segment is made by means of a central screw which also holds it in place' this screw providing contact with the primary coil. A brush bears on the circumference of the disc thus formed, to provide the contact which is made and broken during the revolution of the disc. The disc may have a V groove to receive the brush, or any other shape of groove may be used.
