CHARLES D. WALDEN AND MORTIMER I-I. ROGERS, OF NQBFOLK, VIRGINIA.

' EXHAUST-NOZZLE TIP FOR LOCOMOTIVES.

Application filed May 25. 1915.

To all whom it may concern Be it known that we, CHARLES D. lVALonN and MORTIMER H. Roonns, citizens of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Exhaust-Nozzle Tips for L0 comotives, of which the following is a specification.

Our invention relates to exhaust nozzle tips for locomotives or other engines w ierc the exhaust is expelled along with the products of combustion into its smoke stack.

The object of the invention is to provide means whereby the exhaust fills the stack completely without its being thrown from side to side, which renders'the draft poor and results in a loss of fuel, while by our invention the contrary is the case and a great saving of fuel is effected, which has been demonstrated by actual test in railway practice.

Further objects and advantages will be fully described herein and specifically pointed out in the claim hereunto annexed recourse being had to the accompanying drawing forming a part of this specification in which:

Figure 1 is a technical elevation of the front end of a smoke box of a locomotive engine. Fig. 2 is a sectional elevation of our improvednozzle tip. Fig. 3 is a plan of the same. Fig. 1 is a sectional elevation of the front end of a locomotive similar to that shown in Fig. 1 and shows the action of the tip by dashes or broken lines. Fig. 5 is an end view of a circular bridge or bar for the nozzle tip hall, and Fig. 6 is a similar view' showing a square bridge bolt or bar modification.

In the drawing like reference numerals indicate similar parts in all the several. views.

Numeral 1 denotes the front end of the locomotive and is also known as the smoke box.

2 is netting in the front end for preventing sparks, and may be of any desired shape or arrangement.

3 is the stack and 4c is an extension thereof, shown by dotted lines in Fig. 1 which takes the place of a petticoat pipe though our Specification of Letters Patent.

Serial No. 30,329.

invention can be used in connection with both.

5 is the exhaust pipe or stand and is provided with a tip or nozzle 6; the tip or nozzle is provided with a flange 7 with wet holes 8 so that it may fit a corresponding flange upon the stand 5 or boti stand and tip may be cast in one piece, as desired.

At a suitable distance from the upper edge of the tip or nozzle suitable holes are bored for the reception of the bridge bar or bolt 9 which may be inserted across the diameter of the tip. The brid e belt or bar may be circular in cross section as shown in Figs. 2, 3, and 5 or may be of a square cross section as indicated in Fig. 5.

The bridge usually consists of a head 10, Fig. 2 and a projecting end through which a key or collar 11 may be inserted in a suitable hole to keep the bridge in place. may also rivet the ends of the bridge as shown in Figs. 3 at 12, or secure it in any convenient manner.

13 is a metal ball usually made of cast iron and has a hole diametrically through it for the passage of the bridge bar 9 and adapted to be slidably mounted upon it.

The bridge bar is provided with a number of holes, 14, suitably located so that by means of the key and collar 15 passing through the ball it may be adjusted along the bridge for any distance either in the center of the tip 6, or to each side of the center, as may be found necessary.

15 is a key passing through the ball 13 to hold it in place upon the bar or bridge 9 at any point. The ball also may be secured by the bridge bar by means of a set screw 16 as shown in Fig. 6.

Referring to Fig. 4:, 17 represents the exhaust after it is spread upon leaving the tip 6 and by means of the ball 13there is a conical space 18 of a less pressure due to the deflection of the ball and in this manner the exhaust fills the entire stack as at 19 in Fig. 4, and greatly increases the draft and improves the combustion of the fuel.

We claim:

A device of the class described and in combination with an exhaust nozzle tip, a spherical laterally adjustable deflector or aiiixed our signatures in the presence of two Witnesses.
