Cleanliness and Simplicity in Operation are Claimed as the Merits of this Form of Lever.
ANEW form of brake lever known as the " Sanspareil " has recently been shown to us. It differs from other forms in the fact that there is no trigger or plunger to be operated whilst the lever is being released from the " on position. To operate it, the driver simply pulls the lever backward until
the necessary braking effect is obtained and then, if let go, it will remain in that position, whilst, to release the brake, all one has to do is to push the lever forward. There is no need to give the lever an extra pull backward to induce the catch to let go. The absence of any trigger or plunger gives to the lever a very clean and simple appearance.
The mechanism is simple. The lever is composed of two parts, the lower part being keyed to its shaft in the usual manner. The rack may be of the single or double type. The upper part of the lever is joined to the lower by means of the hinge shown, the upper part being milled out to receive the lower, a pin uniting them. To the rear of the upper part is a boss which contains the spring-actuated plunger (A), the lower end of which engages in the rack when the lever is in the position shown in full lines, which represents it when at rest in the " on" position, also when being applied.
To release the brake the lever is pushed forward. At the position shown in the dotted lines the catch (C) presses on the spring plunger (B), depresses it and slips over the point (as again shown in dotted lines), thus forming a stop which carries the lower part with it and at the same time lifts the catch (A) out of the rack.
The parts are shown separately on the right, as their form can be more clearly understood. Particulars can be obtained from Messrs. B. Smith and Son, Bingley.
