Abstract
This is a device for protecting a persons head while working in a hazardous environment l.e. steel industry - welding, grinding or other places where there are hazards to health (lungs, eyes and ears) and a person needs face and head protection from flying particles which may harm an individual.
This invention consists of a helmet with a face shield. The helmet also consists of two (2) air filters in which each has a fan to propel air into the helmet. The fans have a rechargeable battery pack for a power source. On the bottom of the helmet is provided a piece of nonflammable material, quite soft and flexible, to provide protection to the throat and neck area from foreign materials and ultraviolet rays.
The helmet being made of materials designed to provide the same protection as a hard hat.

SPECIFICATIONS
This invention relates to a helmet being placed on a person's head, and being held in place by a type of headgear similar to that of a welding helmet or hard hat. This device provides protection for oneself while welding, grinding or working where there is dust or to a certain extent a chemical hazard, to one's head and neck area or lungs.
It is common practice to use several pieces of equipment to provide this protection. The neck area is not very commonly protected. The first item on one's head is called a "beany". This is a cloth type of he~dge~r which fits closely to the top of the head to provide protection from sparks and foreign 2 1 8492q material. The person will put on an air respirator which is held in place by several elastic bands. The respirator must be secured tightly to one's head to be efficient. The next item to put on is safety glasses which do not fit properly because of the respirator. The ffiurth item to be used is either a welding shield or a clear face shield, depending on the particular job being done.
This equipment is inefficient because of the length of time it takes to be put on. It is very hot and the respirator develops moisture on the inside, next to the face. The glasses are prone to fogging up and all this equipment is very uncomfortable. It still does not provide any protection to the neck area.
I have found that these disadvantages may be overcome by using one (1) piece of equipment. A
helmet which covers the entire head with a piece of cloth type material (including leather) - attached to the bottom ofthe helmet, can provide much better protection. This el;",;~tes the use of several pieces of equipment and is much quicker to put on and take off. This provides complete head and neck coverage where the other method does not.
In drawings which illustrate embodiments of the invention, Drawing No. 1 is an isometric drawing of the entire unit, Drawing No. 2 is a cross-section of Drawing No. 1. The line running between arrows 1 & 1.
The helmet illustrated, comprises of a face shield No. 1 of Drawing No. 2 which is made of clear material of suitable quality to provide safety and protection. This face shield opens on hinges which are attached to the left side of the helmet. The face shield has an air exhaust value, No. 2, at the bottom to provide an air exhaust port. The spark protector, No. 3, which is attached to the bottom of the helmet, provides protection from sparks and ultra-violet rays as well as other foreign materials. This material 2~929 may be made of any non-fl~mm~hle material which is quite flexible and of such consistency as to be able to stop ultra-violet rays.
The fans, No. 4, which have a flow rate of 5 c.f.m., force air into the helmet through air filters, No. 5. The fans are powered by a rechargeable battery.
The air that is pushed into the helmet provides clean air that the wearer is able to breathe, any excess air is pushed out around the neck, thus keeping dirt and other foreign materials out. This way of providing air, helps to keep the inside area ofthe helmet cool which in turn has a cooling effect for one's head.
The fans are located such that they can only move air that is pulled through the air filters. The air filters, No. 5, are located on the outside area of the helmet. These filters are replaceable and are subject to Health and Safety regulations pel ~ail~ing to that area of safety that the wearer is working in.
The helmet, No. 6, is of such a style as to encompass one's entire head except for the face area which has a dirrel el.l shield. The material and design of the helmet are such that it is able to pass the regulations for hard hats and to stop ultra-violet rays from a welder.
The headgear, No. 7, is used to attach the helmet to one's head. This headgear is of material and and style such as similar in design and quality as that of a welding helmet or hard hat.
Item No. 8, is commonly known as a pin which such items as a welding shield or clear shield may be attached to.
The welding shield, Drawing No. III, is made of materials known to be suitable for this job. It has a glass lens in it of suitable shade and quality as to be called a welding lens. This shield is det~ch~hle so that the helmet may be used for other types of work.
