. The Street railway journal . he thermal efficiency of the engine is as highas 35 per cent. In general outward appearance, the Diesel oil engine resemblesthe ordinary type of steam engine. The reciprocating parts areall enclosed within the engine ^ousing which is fitted with de- tachable plates for easy access. The Jewett City station con-tains two engines of 75 hp each, and each drives a 60-kw Westing-house single-phase 60-cycle alternator. The engines are guaran-teed to operate on 0.47 lbs. of oil per brake horsepower-hour atfull load, and on 0.5 lbs. of oil per brake horsepower-hour fromfaction load to full load. With oil at 4.6 cents per gallon thismeans about one cent per kilowatt-hour. SAFETY CAR STRAP The accompanying cut illustrates the Myers Y-formed safetycar strap which has very recently been placed on the market.This strap, which marks a great advance upon the ordinary singlestyle, is designed to prevent accidents to passengers when a caris going around curves or when it is suddenly stopped or started, . SAFETY CAR STRAP as the strap does not slide along the strap rod like ordinarystraps. With this form, the effect is the same as if the passengerwere holding on to two straps. Straps of this type do not tend to accumulate at some onepoint on the rods on account of car vibration, and they are nevernear enough to each other to enable a passenger to hold two inone hand. Experience has shown that accidents are more likelyto occur at the ends of a car rather than at the center, and it istherefore advisable to place a number of straps at the extremeends, which can be done by attaching one end of each strap in-side and the other outside the end rod supports. The strapbranches are each 6 ins. long and are furnished with buckles andholes enabling each branch to be lengthened about 3 ins. Thelength of the middle piece is about 11 J/2 ins. For the convenienceof the passenger who is obliged to stand the handle is paddedwith fine, soft leather, and medicated to preven
