Lifting Tackle.

The sender of the following communication has been awarded the extra payment of Si. this week..

[2267] " H.A.B." (R,otherhant) writes : "The accompanying sketches illustrate a couple of useful accessories for the garage. One is a loose head for a screw-jack, and.may be made in various forms according to requirements. It needs no description. Thor drawing is sufficient, indication both as to its use and • its method of application. The other is a steel head for a wooden pinchbar. This is fitted with a roller turned down, as shown, for a couple of straps, which hold it in position beeeath the bar. It will be found a very useful tool for moving vehicles about the garage when their wheels are not in a fit state to be set upon the ground."

Utilizing. Old Oil.

[2268] "'W.D.J." (Walthamstow) writes :—" With the increase in C01111:10 tition between the users of road transport vehicles, it is essential to practise economy wherever possible. In this connection engine oil, which is comparatively expensive, is usually wasted when withdrawn from the crankcase, but by mixing it with sufficient thick greaAe to increase its consistency to the necessary amount, it can usually be employed for such parts as the gearbox and differential, where the small amount. of carbon contained in the oil will not ho any damage ; in fact., it, appears to act in the same way as graphite, and to fill up the pores in the metal. Another advantage is that the consistency of the oil can be varied to suit the temperature, as in hot weather a thicker oil is naturally required."

Getting Home on a Broken Spring.

[2269] " R.C." (Waterfoot) writes .— " When about 50 miles from home with 'a fully-laden three-ton lorry, I had the misfortune to break the top leaf of a rear spring. As the fracture occurred about 4 ins, from the rear end Of the .spring, the reault wasthat the body dropped down on to the wheel. I had no means of getting a new one, but contrived to get home by adopting the following expedient. I procured a block of timber 8 ins. by 4 ins_ and 2 ft.. long. This I sawed in two, and nailed the two pieces together in the forte of a T, as shown in the sketch. I then jacked-up the lorry body until there Was .room to' get this timber between the body .ancl_. spring. I nailed the top portion of the T to the underside of the body in such'

positioe that the underside of the. block rested on the top of the spring. So equipped, I was able to complete my journey without any further trouble."

Improving an Oil Gauge. -*

[2270] TT G.M.T." (Stroud) writes .— "I used to have a lot of trouble at one time with the oiling system of a wellknown lorry, which embodies a glass gauge fitted on the dash. The inlet to this gauge was through a diaphragm having .an aperture only 1-16th of an inch diameter, and the result was that if a small-particle of carbon was carried over by the oi! from the engine, it was liah:e to get into the hole and stop the circulation. The consequence was that when the oil had been m use for a reasonable length of time and therefore carried quite a lot of carbon, I used to have to remove the oil pipe and clean it out several times a day. As I got tired of this, I decided to try to discover some means of avoiding the trouble, and ultimately derived satisfaction from the device whiCh is shown in the sketch.. I soldered a piece of wire gauze on to a copper ring of such a size that it would just nicely fit into

the inlet pipe of the gauge. It was placed rin position with the copper wire against the diaphragm of the oil supply pipe, thus avoiding any restriction of the area of the hole in that diaphragm."
