referring now to fig1 there is shown a chain saw operator who may be located in a small enclosure 10 that through appropriate mechanism is raised above the ground to reach upper tree limbs that might , for example , be interfering with electrical or telephone wires . the operator is using a chain saw 12 to cut a tree limb 14 in which the limb is above the operator leaving his chest and shoulders exposed to the area of operation of the chain saw . the operator is wearing a vest of the present invention generally indicated by numeral 16 and shown in greater detail in fig2 through 4 . the jacket is made up of an upper vest portion 18 that surrounds the wearer at the upper portion of his chest and back . this portion 18 is sleeveless and provides openings 20 where the sleeves would otherwise be connected . a collar 23 encircles the neckline of the member 18 . a lower or skirt portion 22 is designed to surround the wearer about his waist area and is secured to portion 18 at discrete points 24 which may be sewed locations . in this manner vent areas are provided so that air can enter inside the upper or vest portion as shown by arrows 26 in fig4 . the large openings 10 also aid providing ventilation for the user . the skirt portion 22 may have one or more inside pockets as 28 in fig2 . preferably there are no outside pockets on the garment which would be hazardous to the operator by catching onto branches or other items . both of upper or vest portion 18 and the skirt portion 22 may be made of a material such as nylon which provides flexibility and comfort to the wearer . two sheets of padding material 30 and 32 are sewed to the vest portion 18 to cover the upper chest area of the operator . it is seen that these pads extend backward over the shoulder and as a result protect the user &# 39 ; s chest and shoulders . the padding material may take various forms and it has been found that one especially effective type is a fibrous padding known as prolar and sold by the elvex corporation of bethel , ct . another example of a type of padding material for the purpose of jamming a saw chain is that disclosed in u . s . pat . no . 4 , 280 , 342 . in the event that the rotating saw chain comes in contact with the padding , the fibers will be drawn into the chain saw sprocket to jam and stop the operation of the saw and in that manner preventing or minimizing injury to the user . a zipper 34 is provided at the front edges of both the upper vest portion 18 and lower skirt portion 22 to close the garment . thus it is seen that a garment is provided to protect the upper body portions of a chain saw operator . it has special utility for the use of chain saws in cutting overhead tree limbs where the upper portion of the body is particularly exposed . having thus described the invention with particular reference to the preferred forms thereof , it will be obvious that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims .
a sleeveless jacket that would be worn by the user of a chain saw . the front and shoulders of the jacket are padded with a material that jams a chain saw if it cuts into the padding to protect the user from being cut by the saw .
