JACOB FULMER, OF ASHEVILLE, NORTH CAROLINA.
EXHAUST-NOZZLE.
SPECIFICATION forming part of Letters Patent No. 439,499, dated October 28, 1890.
Application filed May 6, 1890.
T0 on whom it may concern:
Be it known that I, JACOB FULMER, a citizen of the United States, residing at Ashe ville, in the county of Buncombe and State of North Carolina, have invented certain new and useful Improvements in Exhaust-Nozzles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to exhaustnozzles which are especially designed to be used in connection with locomotive, marine, stationary, and portable engines for creating a draft through the furnace, thereby producing a saving in fuel and having a power making it possible to create means by which a reserve can be called forth in an emergency, this reserve being a desideratum in locomotives which are designed to ascend and descend steep grades and in accordance to the requirements and work performed.
A further object of the invention is to construct a nozzle which can be readily adapted for any kind of fuel to be burned, the load of the engine, and the pitch of the grade, and which will be under the control of the engineer at all times.
The improvement consists, first, of an an-- nular nozzle placed with reference to the stack or chimney so that there will be no external draft; second, an adjustable annular nozzle for varying the annular escape-space, thereby altering the draft; third, in the instrumentalities for relieving the connections between a semicircular lever and the adjustable cylinder of strain, and, fourth, in provisions for compensating for wear between the upper end of the adjustable cylinder and the base of the stack.
The improvement consists, also, in the novel feature and peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed, and which are shown in the accompanying drawin gs, in which Figure 1 is a longitudinal section of the extension front of the locomotive-boiler, showing the application of my invention. Fig. 2
is a section of the invention at right angles Serial No. 350,840. (No model.)
to Fig.1 on the line Y Y of Fig. 1. Fig. 3 is a perspective view of the adjustable cylinder detached, showing the adjusting-yoke in position. stack-base. Fig. 5 is a perspective view of the ring forming the lower part of the nozzle. Fig. (5 is a front view of the stack-saddle, showing the petticoat-pipe in dotted lines. Fig. 7 is a side view of the stack-saddle, the yoke being in place. Fig. 8 is a section on the line X X of Fig. 1. Fig. 0 is a bottom plan view of the stack-saddle. Fig. 10 is a bottom plan view of the exhaust-pipe.
In the drawings A represents an extension front to a locomotive-boiler of ordinary constrnction.
B is the stack-saddle.
O is the stack.
D is the stack-base.
E is the petticoat-pipe adj ust-ably connected with the stack-saddle.
F is a spark-arrester gauze cylinder, which extends from the petticoat-pipe to the bottom of the extension front. The nozzle is composed of the ring G, which is secured in the lower end of the stacksaddle, preferably by the annular shoulder g on the said ring resting on a corresponding shoulder (Z in the said stacksaddle and by the screws 9', which pass through the said ring and obtain a bearing on the lower end of the said stacksaddle. The upper end of this ring is beveled inward. The cylinder H, placed within the stack-saddle, is beveled at its lower end in an opposite direction to the upper beveled end to the ring G and is adapted to overlap the said beveled end of ring G and form the escape-space it between the beveled ends of the cylinder and the rings. The stack-saddle is recessed opposite the opposing ends of the ring G and the cylinder II to form the annular steam-chamber h into which the exhaust steam is discharged and from which it escapes directly into the stack through the annular escape-space h. A steam-tight joint is formed between the upper end of the cylinder II and the upper end of the stack-saddle to prevent the escape of steam between the said cylinder and the stack-saddle, thereby utilizing all the steam for creating a draft through the stack. This steam-tight joint is Fig. at is a perspective view of the eifected by the packing-rings I 1, which are sprung into corresponding tubes it" in the cylinder H. The cylinder H is vertically ad justable with reference to the ring G to vary the size of the annular escape h, being adjusted, preferably, by the oblique slots J in the sides of the stack-saddle, the screws or bolt passing through the said oblique slots J and engaging with the cylinder H and the yoke K, which is connected at its ends with the cylinder H by the screwsj. To prevent wear on the bolts or screwsj the blocks kare provided with blocks m, which are adapted to travel in the oblique slots J, and which are I 5 mounted on the said screws j. The yoke K is provided with a swivel k on an arm-extension 10 through which the rod 10 screws. This rod 10 extends within convenient reach of the engin eer, and is provided near its outerend with the collar k which clamped between two plates k k, which are bolted on a suitable part of the en gineer-cab, and which rod is provided near its outer end in the crank it, by means of which the engineer rotates the said rod 70 and effects a shifting of the yoke K either to the left or right, thereby increasing or diminishing the annular escape h. The upper end of the cylinder H has a series of incline portions H, which have a pitch corresponding to 0 the pitch of the oblique slots J, and which are pressed upon by the projections Z depend- 1ng from the stack-space B. By reason of the pitch of the incline portion L and the slots J being alike, the projections Z will obtain a 3 5 bearing on the incline portions L at each and every adjustment of the cylinder H, thereby relieving the blocks 7c and the screws j of all strain in a vertical direction. This operation will be better understood when it is remem- 4o bered that the steam in its passage from the steam-chamber h and through the cylinder H will exert a lifting force on the said cylinder which is very material and constant. This strain would be sustained solely by the screws j if the inclined portion L and projections Z were not provided. Obviously the construction shown and described admits of the projections Z taking up the strain. The bolts M, which fasten the stack-base to the stack-saddle, pass through slots in in the outer flange in the stack-base, thereby permitting a limited movement for adjusting the said stack-base on the stack-saddle.
The purpose of having the stack-base adjustable on the stack-saddle is to allow adjustment between the projections Z and the incline portion L to compensate and take up wear, or to cause the said projection Zto bear on the incline portion L when adjusting the parts.
ing the vacuum in the stack and creating a draft through the furnace. The draft can be varied by regulating the space h-the smaller the space h the greater the draft; conversely, the larger the space h the less the draft. It will be observed that there is no exterior space to the nozzle. Consequently the entire force'of the steam is utilized to create a vacuum and a draft through the staff.
An important element in my invention is the facility with which the nozzle can be cleaned, the cleaning being done from above, as the cylinder H and the ring G are removable through the upper end of the stack-saddle, the stack-base being first removed.
The yoke K is held in a horizontal position by the lugs n, which extend from the side of the stack-saddle. which is designed to rest on the lugs n inclines in conformity to the inclination of the slots J'. The yoke can be arranged to operate on either side of the stack-saddle.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1.. The combination, with a smoke stack or flue, of an annular nozzle arranged within the said stack or flue or an extension thereof and That portion of the yoke W closed to any exterior draft or influence, sub- 7 stantially as described.
2. The combination, with the smoke stack or flue of a boiler-furnace, of an annular exhaust-nozzle arranged wholly within the said stack or flue or a prolongation thereof and closed to any exterior influence, of means, substantially as set forth, for varying the space between the component parts of the nozzle, substantially as described, for the purpose specified.
3. The combination, wit-h the stack-saddle, of'the ring G and the cylinder H, the opposing ends of the ring and cylinder overlapping and being oppositely beveled and having a steamspace formed between them, said stacksaddle having an annular steam-chamber surrounding the opposing ends of the ring and cylinder, substantially as set forth.
4. The combination, with the stack-saddle having the annular steam-chamber h and the ring G placed opposite the said steam-chamber and having its upper end beveled, of the cylinder *H', inserted in the stack-saddle and having its lower end overlapping the beveled end of the ring and oppositely beveled, and the yoke having connection with the said cylinder through oblique slots formed in the stack-saddle, substantially as specified.
5. The combination,with the stack-saddle having an annular steam-chamber and the ring G, of the cylinder H, having connection with the stack-saddle through oblique slots formed therein and having inclined portions at its upper end, substantially as and for the purpose described.
6. The combination, with the stack-saddle having an annular steam-chamber and the ring G placed therein and having its upper end extending within the said steam-chamber, of the cylinder H, placed within the stacksaddle and having connection therewith through oblique slots and having inclined portions at its upper end, and the stack-base having projections to bear on the said inclined portions, substantially as and for the purpose described.
7. The combination, with the stacksaddle, the ring G, the cylinder H, having connection with the stack-saddle through oblique slots formed therein and having inclined portions at its upper end, of the stack-base having projections to bear on the said inclined portions of the cylinder and adjustable on the stacksaddle to bring the projections in closer relationship with the said incline portions substantia-lly as described, for the purpose specified.
8. The combination, with the stack-saddle and the adjustable cylinder II, of the yoke having connection with the said cylinder through oblique slots in the stack-saddle, and the rod having a swivel-connection with the said yoke and extending in convenient reach of the engineer, substantially as described, and for the purpose set forth.
9. The combination, with the stack-saddle, of the nozzlecoinposed of the ring G and the cylinder H, which are removable through the upper end of the stack-saddle, substantially as and for the purpose set forth.
10. The combination, with the stack-saddle having an annular steam-space and the ring G and arranged to extend within the said steam-chamber, of the vertically-adjustable cylinder II, and packing interposed between the said cylinder and the stack-saddle, substantially as described, and for the purpose specified.
In testimony whereof I afiix my signature in presence of two witnesses.
