C. A. GEIGER, No. 2620, dated 18th February, 1915.—The accompanying drawings shows a partial plan and elevation in section of the drawbar construction for the trailer. The main. framing ismade of channel-section steel mounted by ordinary 'eemi-elliptic springs upon the axles. The drawbar is teleicopic with a spring connection between the two parts and it 4 pivoted to a cross-member on the frame above the axle so Mat it can swing laterally. A locking-pin is provided to Oecure it in the middle position when desired. ' All the wheels of the trailer a-re mounted on stub axles and a steering sod connected to these axles is coupled to the drawbar, so that lateral movement of the drawbar gives, the required steering effect.
Each end of the trailer is constructed in the same manner so that it can he-readily reversed so as to be used with equal facility in either direction. A further advantage of this invention is that the various parts are arranged so asAo‘obtain perfect resiliency of the trailer while at the same time allowing for lateral, vertical or torsional movement of the frame relatively to the axles withbut in any way interfering with the steering of the trailer.
M. W. DADEY and E. SELEIIRG, No. 11,503, dated 9th ,August, 1915.—For assisting a vehicle through sand or mud, this invention provides the side extensions to the tread of the ;wheel, consisting of flat metal, fabric bands or metal chains, p.upported by a number of steel saddle members on the tire. I.' The extension rim, which can be quickly attached to or detached from the ordinary wheel rim, does not, even if left on the wheel, interfere in any way with the usual working of the 1 heel. R. BELL., No. 17,172, dated 7th December, 1915.—This specification describes a neat driving gear for magnetos in which provision is made for advancing or retarding the ignition as may be desired. •
The drive is effected by gearing similar to a differential gear, one crown. wheel being fixed to the armature shaft and one on the driving shaft. The pinion engaging them is mounted in a cylindrical casing which is adjustable by means of a worm-gearing. The normal setting of the ignition is effected by turning this casing to the required position, and then a lever on the operating worm is coupled to the driver's controlling lever to provide for the small adjustments required in driving.
C. V. ROTE, No. 8817, dated 15th June, 1915.—This invention provides a convenient construction of brake-head to which renewable brake shoes are easily and securely connected. The brake head is hollow and the brake-shoe is provided with lugs on its back which enter the bra,ke-head. Inclined key-ways or slots are cut in the brake-head and in these lugs, so as to register with one another and lock the shoe in position by
means of a key-member. The sloping of the keys ensures that they are held in by the action of gravity. Each brake-shoe is formed with undercut recesses in its front face and these are adapted to receive the lugs of another brake-shoe. When, therefore, the shoe becomes dangerously worn a new shoe is inserted in the head_ and the old shoe is mounted on the front of the new shoe so that it can be entirely used up.
