lmlorc rvlorroil to, Whii'h provided with an tubing, before mentioned.

tubing, shown in Fig. 7, as connecting the intake nipple a, to, which is attached the adjacent end of a tube or metal pipe conveying compressed air from the airpump, which is partof the usual air-brake mechanism, while an outlet pipe a receives the adjacent end of the flexible tubing communicating with the eye-pieces of the goggle frame and conveys the air from said tank to said goggle frame, only portions of which tubing or pipe are shown in the drawing.

In Fig. 7 is shown,,a piece of metal tubing (1, supplied with a globe valve A to regulate the llow of air from the tank to the eyepicces, said. metal tubing having its ends secured. in the adjacent, ends of the flexible nipples of the metal pipe (1 with the air tank, may be omitted and the metal pipe may be continued direct from the air tank to the desired point, so as to bring the globe valve A to a point within easy reach of the opcrat or, but any other suitable valve may be used in place of the globe valve, here mentioned.

An air accumulator, which is preferably in the form of a funnel, may be applied to the front part of the vehicle, having its open end forwardly and its converging sides rearwardlv disposed, forming; the apex of a horizontal cone, which apex is secured my 'the forward end a of the third branch, so as to have interior connection thcrcthrough with the fork A conducting the air accumulated by .raid funnel intothe flexible tubing; of the eye-pieces. The construction of this funnel and its tubular connection being so well known that the separate illustration thereof is deemed superfluous.

it will here be remarked that I. do not limit myself to the precise construction hcreinbcfore described, for minor alteratrons may be made without departmg ironr the spirit of the invention,

The invention having thus l'iecn ascerrtained and described, and the manner in which its functions are performed fully shown and. set forth what is considered new The fleXibl e plate l'ormet and desired to be secured by Letters Patent 1s:

1. in a device of the class described, consisting of an eye protector, a frame formed of two adjacent tubular circular eye frames formed with openings in their periphery, a tubular nosebridge connecting" said eye frames, means for connecting said eye frames to flexible pi ing, and meansfor supporting said flexil) e tubes and securing the device to the head of the wearer, for the purpose set forth.

2. in a device of the class described, consisting of an eye protecting frame formed of tubular circular eye frames; openings formed in the )6ll)l1( 1, of said eye frame, a tubular nose-l ri fge the ends of which are secured to the adjacent sides of said eye frames, nipples secured to said eye frames, flexible tubes having their forwardends secured to said nipples and their rear ends secured to a if-shaped connectin pipe, means for circulating air through said tubes and nipples, and means for liberating said air from the openings in the periphery of said frames.

3. in a device of the class described, an eye protecting frame, formed of two tubular eye frames, openings through the walls of their periphery, a tubular nose-bridge connecting said eye frz'nnes at adjacent points up'van their periphery, nipples secured to said eye frames at their extreme opposite outer cdg0s,lleXiblc tubes having their forward ends secured to said nipples, a Yshaped tubular connection connecting the rear ends of said flexible tubes with each other and to a source of air supply, a curved slide 1 with clam ings embracing said flexible tubes and slidab y ad irstable thereon.

in testimony whereof I ahix my signature, in presence of two subscribing witnesses.
