STEAM-EXHAUST NOZZLE.

Application led March 19, 1915.

To all whom t may concern:

Be it known that I, FREDERICK Minus immuun, a citizen of the United States, re-r siding at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements 1n Steam-Exhaust Nozzles; and I do declare the following to be a full, clear, and rexact description of the invention, such as ywill enable others skilled in the art to which it appertains to make and use the same, reference being had to thelaccompanying drawings, andto the letters and figures of'reference marked thereon, which form a part of this specification. f

My invention relates to steam exhaustJ nozzles, and more particularly to nozzle tips in use in locomotive or other steam engines wherein steam is used to create a'draft; the principal object of the invention being to provide a nozzle* with an adjustable tip and means for operating or regulating the tip from the engine cab, wherebythe fireman may secure a desired blast through the grates.

In accomplishing this object I have pro vided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure I is a perspective View of an adjustable nozzle tip constructed according to my invention. Fig. II isa frontview of the device and a portion of the smoke arch, showing one of the operating rods extending through the arch. Fig. III is a side view of the nozzle showing the operating rod and its mounting on the engine cab. Fig. IV; is a plan View of the nozzle tip.

Referring more in 'detail to the draw-y ings 1 designates the upper portion of an exhaust nozzle of the type used in the ordinary locomotive, and which is located in the smoke arch directly below the stack (not shown) and adapted for directing a column of exhaust steam through the stack to create a partial vacuum throughy the arch and produce a forced draft through the fire.

Formed integrally with and extending laterally from the nozzle is an annular fiange 2, and seatedkon said flange is a nozzle tip 3 comprising a slightly tapered cylindrical portion 4 conforming iny size with the upper portion of the nozzle l, and having side lugs 5 provided with apertures for receiving bolts 6 whereby the tip is secured l to the flange 2.

the tip 3 and formed integrally therewith are wings 7 which extend throughout the height of the tip and have longitudinal grooves therein opening through the outer edges and both ends of the wings to provide guides or slideways 8 for the posts 9, which are adapted for free travel therein; each of Lthe posts 9 being beveled outwardly from its lower inner corner in order to forma wedge face that will force cinders, or the like, that may accumulate in the bottom of the wing sockets or guideways 8, outwardly from the guideways and keep the latter clear to prevent the cindersfroin interferring with the full vertical travel of the posts. Each of the posts 9 is also provided with grooves 10 in its side faces and the grooves extend throughout the length of the post to provide channels through which fine cinders or dust that may accumulate at the bottom of the socket, within which the post is movh able, may be drawn out by the forced draft in the nozzle to clean the socket and scour the same to insure free vertical movement of the post.

The posts 9, which are arranged at diametrically opposite sides of the nozzle tip, are connected by and support a bridge 11, which extends across the tip opening to divide the steam blast, andis turned downwardly and formed into a stepped blade 13-15. The 'center portion 13 has a downwardly'directed knife edge 14, and portions l5, at the ends of the center portion, are also provided with downwardly directed knife edges, inorder to divide and spread the steam blast, and increase the drawing force thereof according to the depression of the bridge.v IVhen the bridge l1 is in its lowermost position it will be supported by its end edges 16 resting on the top of the nozzle tip; it being apparent that when the bridge is in its lowerinost position, the knife blades will divide theblast within the tip to increase the draft to a maximum and thereby effectuallv tear and stir up the fire when feeding with `bad coal, or when the ire shows signs of getting dirty, clinkering. etc., and it is also apparent that the draft may be regulated bv elevating the bridge to different points for securing the desired draft, andy collars 22 which anchor the shaft against longitudinal movement while not interfering with lrotary movement thereof, and also fixed to the shaft outwardlyfrom the collars 22 and preferably bythe set screws 23, are the hubs Qfeof arms 25, whichr latter extend across the sockets in the' wings 3 and have slots 26 therein through which pins 27, that are rigidly mounted on the posts 9 and eX- tend outwardly through the ksockets 3, prof ject loosely so that the Vslotted arms may slide over the pins. y l

The slot 26 in each of the arms 25 is beveled outwardly at its ends in order to'form free outlets for cinders that may accumulate within the slot, and thereby prevent stoppage of the slot that might interfere with the full travel of thel arm over its pin and limit the vertical. adjustment of the bridge.

The arm 20 at the outer end of the shaft 1S projectsbetween spaced stops 29 that are mounted on and project from the side of the smoke arch in order to limit the movement of the arm and relieve the lever and bridge mechanism from strain.

Pivotally connected with the outer end of the arm is a rod 30 which is formed insections and provided with adjusting sleeves 31 whereby the length of the rod may be varied to regulate the lift of thebridge whenmoved by the rod handle 32 which isconnected with the outer end of the rod.

The handle 32 comprises a latch bar member 33, which extends through a guide bracket 34 having an upwardly projecting latch tooth 35 thereon adapted for projection into the notches 36 in the lower edge of the bar, so that the bar and rod may be held in an adjusted position to retain the bridge at a proper elevation relative to the nozzle ti pThe bracket 34 preferably comprises an arm 37` which is mounted on and projects from the .smoke arch and has the tooth 35 formed integrally therewith; the guide part 38 comprising a U-shaped rod, which is mounted on the bracket and projects above the tooth, as illustrated.

j In using my improvement, presuming the parts to be constructed and assembled as described, should the lire clinker or choke becausevof bad coal or otherwise, the bridge may be lowered into the nozzle tip by manipulation of the latch rod from theengine cab, so that the blast is divided and Vrestricted in the nozzle to ei'ect a stronger pully through the grates and fire that will tend to clean the fire; the strength of the pull being regulated lby position of the bridge and the latch mechanism being so arranged that .whenV the latch is at one Y position the bridge will be at its lowest point and when at other positions at other predetei-mined points in the nozzle, so that the fireman can determine the effect of the blast by the position of the latch; it being apparent that when the bridge is at its lowest point a wide diversion ofthe exhaust steam is efected, which causes the stack to be entirely llled with the escapingl steam and produces considerable vacuum in the smoke arch that causes asharp blast jon the fire; and that-ateach successive higher step of the bridge the steam is diverted .or choked rto a lesser ,degree until when'the bridge iseleA- vated to its highest point, a full opening ofthe nozzle is provided that produces noradditional vacuum in the smoke arch because Vofthe presence of the bridge.

Having thus described 4my invention, what' I claim as new therein and desire to secure by Letters-Patent, is :fl' 1. The combination with, an exhaust nozzle, of a bridge crossing saidrnozzle and comprising blades arranged in vertically stepped relation, and means for raising or lowering the bridge.
