A CHANNEL STEEL SIDECAR FRAME.
A channel steel framed sidecar made by the Gosford Engineering Co., Coventry, and described on this page. The inset shows the method of springing the rear portion.
We recently had brought to our notice the sidecar frame made on novel lines by its designer, Mr. W. E. Boyes, of the Gosford Engineering Co., Coventry.
The frame, which is attached to the motor cycle at the usual three points, viz., front down tube, seat tube, and chain stays, is made of channel steel. The body, which is made by the Bramble Mfg. Co., as will be seen, is suspended on two threequarter elliptical springs at the rear, and the front portion on one semi-elliptical spring set transversely to the frame.
The present type of body is, we understand, only experimental, as in future the front portion will have an upward curve, so that if at any time the front stay of the sidecar should come loose or break, the makers claim that the sidecar will skid along the ground until the engine may be stopped.
One of the features of the frame is that there are no brazed joints or castings on any part of it. Another point worthy of note in the manufacture of the sidecar is its weight, and we are told that the complete machine without body scales exactly 48 lbs. Although being slightly under the average weight of this type of vehicle, it is of sound construction, and well made throughout.
