WIND-GUARD.

' SPECIFICATION forming part of Letters Patent No. 424,212, dated March 2,5, 1890.

Application med May 2s, 1889.

Serial No. 312,463. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN KEANE, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in find-Guards for Chimneys and ventilators, of which the following is a specification.

4My invention relates to wind-guards or protectors for chimneys and ventilator-pipes, and more particularly to the production oi' animproved guard for use on ships and vessels.

It consists in certain novel construction and combination of parts, as hereinafter fully described, producing a guard that is especially adapted for use on shipboard to secure constant upward draft in a smoke-pipe or a ventilator-pipe.

The nature of my said invention and the manner in which I proceed to construct and produce the same will be understood from the following description, in which the accompanying drawings are referred to by figures and letters.

Figure lis a side elevation of my improved guard for a chimney or smoke-pipe. Fig. 2 shows a modification that is designed for use on the end of aventilator-pipe on shipboard.

A is the end of the guard that is set directly upon the pipe to be protected, for which purpose it should have suitable size andform to makea close .fit over the end of thepipe. The upper end of this part is turned downward to produce the short limb AX, and the end of this siphon portion is turned outward to bring the mouth a2 substantially at rightangle to the long limb A. Perpendicularly across this upper end of the siphon, to stand parallel with the main portion A, is iiXed a short pipe B, open at both ends, and having about the same diameter as the shortdmb pipe. These parts form the body of the guard, and are arranged as shown in Fig. 2 of the drawings, `with the short limb of the siphon and the perpendicular pipe across its end placed closely against each other; or, as shown in Fig. l, the bends of the short limb may be larger and the parts set oif with a space be*- tween the sides of the pipe and the short limbA The same operation and results are obtained D, of such size that it will close the pipe B below this side opening when turned down t0 uncover the opening. In this arrangement the pipe B is set closely against the short limb, so that the opening C is readily made through the pipe into the Siphon. rThe damper D is counterweighted, as shown in Fig. 2, and will be :normally held to close the opening C, and will also close the pipeB when turned down and leave Athe opening C open, thus making the draft more direct from pipe A to the upper end of pipe B when down and more circuitous when raised to close the opening C, thus regulating the draft and prevent ing gusts when desired. This opening and damper are not .required where the guard is used on a chimney or smokepipe; but in such application of the guard it will be found desirable, especially on shipboard, to provide screens on the ends of the pipe B, and particularly on the lower ends of the pipe, to retain the soot, and thereby secure greater cleanliness in the vicinity of the cooks galley and other parts where smoke-pipes are brought outside above deck. The screens E E* are therefore provided for covering either the bottom end or both ends of the pipe B, if found necessary.

The screen E is formed with a closed panshaped bottom e to catch and retain the soot and drippings, and has openings eX in the sides covered with wire gauze. Any suitable fastenings can be used to hold it in place on theend of the pipe and to allow it to be removed for cleaningdsuch, for instance, as the well-known pin and bayonet-slot fastening, as I have represented in Fig. 1.

Instead of placing a screen on the top of the pipe, the usual cone-shaped cap G can be fixed over the open end to deiiect the air and keep ont rain. The upper end of this pipe is also made funnel-shaped, as shown in Fig. 2,

IOO

after the manner of forming the mouths of ventilator-caps and for thesame purposenamely, to increase the area of the inlet.

As thus constructed and applied, my improved guard Will be found to operate effectively in all situations where a smoke-outlet or aventilator is exposed to cross-drafts or deected currents. It produces constant upward draft by suction in Whatever direction the Wind or air-currents may strike it, While complete exclusion of rain or of the seais secured. 4

Having thus fully described my invention, what I claimand desire to secure by Letters Patent, is-

l. In combination with a Wind-guard com posed of the tWo parallel pipes A B and the short limb AX, the screen E, having a close bottom e and screen sides adapted tov be applied to and removed Afrom the lower end of the pipe B, as and for the purpose set forth.

2. In combination with a Wind-guard composed of the two parallel pipes A B and the short limb AX, having opening C in the Wall between the short limb and pipe B, and a damper D fitted thereto, and adapted by its size and position to close said opening when turned up and to shut the pipe B at a point below said opening when turned down, i

substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
