| NOTES ON CADILLAC. 1. WEIGHTS. (a) Complete car............... 58 cwt.2 qrs.(without petrol). 40/50 h.p. RR.Car with body of same type............... 49 cwt.2 qrs.(without petrol). 20/25 h.p. RR.Car with body of same type............... 37 cwt.1 qr.(without petrol). (b) Cadillac.................Approximately 19 cwt. 40/50 h.p. RR.Car of same type " 14 cwt. 20/25 h.p. RR.Car of same type " 11 cwt. (c) The accessories on Cadillac weigh about 1 1/4 cwt. On a RR. car of the same type they usually weigh about 2 qrs. 15 lbs. 2. CHASSIS. The design of the Cadillac chassis makes for exceptional rigidity of the main frame or body platform, whilst its suspension system is such that the body is well insulated from road shocks. In addition, the brakes are comparatively poor so that the body cannot be subjected to the severe stresses set up by harsh braking. Again, the road springs can be damped to a limited extent only so that it is not in the power of the driver to interfere seriously with the insulation of the body from road shocks. 3. CHASSIS FRAME. The main frame is 8.250" deep and has a cruciform section 7.250" deep of considerable length. The result is an extremely rigid frame. The 40/50 h.p. RR. frame is 6.325" deep (max.) and has no cruciform section. 4. BODY BRACKETS. There are six body brackets on each side. Except for the rearmost brackets, they are large and very rigid. The rearmost brackets appear to be less rigid. They are so | ||
