GEORGE E. WITT, OF SAN FRANCISCO, CALIFORNIA.

LOCOMOTIVE OIL-BURNER.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed September 19, 1905; Serial No. 279,188-

To all whom it may concern:

Be it known that I, GEORGE E. Wrrr, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Locomotive Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oil burners, and more particularly to those used in locomotives, and it has for its objects to provide a device of this class which shall possess superior advantages in points of simplicity of construction, as well as inexpensiveness and general efiiciency.

In my. invention 1 have made it possible to regulate the size of the flame without the necessity of delicate and readily destructible mechanism.

In my present invention there are no adjustable parts liable to get out of order, as the burner proper is made of a single casting.

Other objects and advantages of the inventionwill appear in the following specifications, and the novel features thereof will be particularly pointed out in the appended claims.

In the accompanying drawings, in which similar letters of reference designate corresponding parts: Figure 1 is a longitudinal central section of the burner. Fig. 2 is a transverse section on the line mo of Fig. 1. Fig. 3 is an end view of the mouth of the burner.

Referring now to the above views, A represents the main body of the burner which is a hollow casting with the central web B which divides the interior into the longitudinal passages C and D, the former for the passage of oil and the latter for steam. Leading to the rear of the upper passage C is the threaded boss E which is adapted to receive the oil pipe; while the passage D terminates in the threaded boss F which receives the steam pipe.

The forward end of the oil passage C is open; while that of the steam passage D is closed with the exception of a transverse horizontal slot (a). The end wall of the passage D, through which the slot (a) is cut, sets back slightly from the extremity of the main casting thereby forming a lip (b) which inclines downward toward the center of the casting as shown in Fig. 3.

From the description so far gone into it will be readily seen that as the oil reaches the outer extremity of the passage C it will flow downward until it reaches the slot (11) when thesteam issuing from the slot will intermingle with the oil and produce the desired result. N

Now directly below\the lowest portion of the lip (b) flame is the result.

is a hollow projection G into which is cut the slot (9). The smallpipe H which is threaded into the pr0jec tion G is provided to carry steam to the slot (9). Now it is manifest that when it is desired to reduce the flame the steam passing through the passage D is cut off and allowed to flow through the small pipe H. Of course the oil flowing into the lip (12) will overflow and finally reach the small slot (g) where the diminished flow of I steam is encountered and a correspondingly small It will be noticed by reference to Figs. 1 and 3 that the upper edges of the lip B dip slightly inward in order to prevent the oil from flowing from the lip until it reaches the lower portion thereof.

The rear leg J and central legs K are merely for the purpose of holding the small pipe H in place.

The construction and arrangement of the several parts of my burner being thus made known, the operation and the many advantages of the same will, it is thought, be readily understood by those familiar with the use of oil burners.

Havingthus fully described my invention, what I claim and desire to secure by Letters Patent is:

1. In a device of the character described, a hollow cas- 7 ing having a central web dividing its interior into parallel .7

upper and lower passages, said casing having means by which said passages may be respectively connected to an oil and steam supply, said oil passage extending through the front end of the casing and said web terminating short of the front extremity of the casing, and said casing'having' a vertical wall connecting with the front end of the web and extending over and closing the front end of the underlying steam passage except for a slit in said wall, said casing having a lip positioned in front of and below said slit, to enable the oil emerging from the oil passage to flow downward over said wall and across said slit into the range of action of the steam issuing from the latter.

2. In an oil burner the combination of a hollow casing having a web which divides its interior into upper and lower passages for oil and steam respectively said Web 'terminating short of the front end of the casing and conmental steam pipe entering said hollow projection and de-' livering steam thereto whereby oil overflowing the lip will flow down over the wall of the hollow projection and into the range of action of the steam delivered through the slit in said projection.

3. An oil burner provided with oil and steam passages having outlets arranged in parallel relation, the oil outlet being provided with a gutter. of maximum depth at the center and having a rear dam wall, a central bottom wall, side walls inclining downwardly from the sides of the outlet to the bottom wall, and barrier lips projecting up wardly from the outer edges of the side walls in parallel lips projecting upwardly from said side walls and inclined 1O relation to said dam wall and inclining downwardly from toward the deepest portion of the gutter and separated to the sides of the outlet to said bottom wall, the bottom form a shelf for the reduced flow of oil therethrough.
