A.J. Morse & Son Three Light Breastplate Feed Commercial Helmet

Product Features

When A J Morse & Son introduced the second generation improved diving helmets they offered the standard helmet in two air delivery configurations, air into the rear of the bonnet, or air into the rear of an enlarged neck ring. The neck feed allowed the bonnet to be free of the air hose making installing and removing it much simpler. It also reduced the risk of the bonnet being unscrewed from the breastplate due to a snagged air hose. The negatives of this design was there is no ducting of the air to the windows for defogging, and the airflow can be a nuisance to the diver by blowing on his neck or into his face. Morse did sell a good number of this model helmets so the downsides did not deter customers. The helmet in and of itself is very attractive with details not often seen on other helmet models. 

This helmet is fitted with a adjustable single spring exhaust valve at the right rear of the bonnet. The valve is adjustable to increase or lower back pressure in the outfit to regulate buoyancy. The valve stem extends into the inside of the helmet, with a large button on same, so that this valve may be opened by a thrust of the diver's head against it, allowing the air to ecape quickly from the helmet.

This style helmet comes with a screw type faceplate, vertical oval side windows and exhaust valve. The helmet is fitted with a "Navy" type non-return valve.  The bonnet is also fitted with two lashing loops and rope hooks if horseshoe weights are used instead of a weight belt.

The breast plate comes with two fairlead clamps for the air and communcation lines fastened closed with thumb screws.

Tin plating and communications are optional at additional cost.
