UNITED STATES PATENT HENRY A. LUTTGENS, OF PATERSON, NEW JERSEY.
LOCOMQTIVEL SPECIFICATION forming part of Letters Patent No. 330,340, dated November 10, 1885.
Application filed April 23, 1885. Serial No. 163,112. (No model.)
To all whomit may concern.-
'whereby the end is attained with greater perfection than heretofore and difficulties are .avoided.
There are conditions in the working of alocomotivewhen it is highly desirable to suppress instead of increasing the fire, and yet it pose have been open to serious objections.
" Some of the plans have been liable to eject smoke and sparks through the apertures. With others it was difficult or impossible to prevent the parts from working with too great looseness or tightness from difference of expansion. All are liable to eject water, which, with the soot washed out therewith from the stack, is unsightly, and, by disheartening the attendants, lowers the standard of neatness and efficiency in the work. I mount an annular damper-plate on a conical seat around the stack, which by partially rotating covers and uncovers apertures. These apertures ad mitting the air communicate with an annular channel which first descends then extends inward through a pocket or smoothly-curved base and then ascends to a less height on the inner side. The whole is a single casting just outside of the proper diameter of the chimney. The several surfaces are rounded and beveled to present a smooth channel to the air. The damper-plate may expand and contract freely on its conical seat,while always maintaining a tight contact therewith.
The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.
Figure l is a side elevation, one-half in vertical section. Fig. 2 is a corresponding section through a portion, taken in a different plane. Fig. 3 is a plan view and a horizontal section taken above the principal parts. This figure corresponds to Fig. 1. Fig. 4 is a plan view showing a modification.
Similar letters of reference indicate corresponding parts in all the figures where they occur.
A is a portion of the barrel of the smokebox. The hole a therein is a little larger than the interior of the stack.
B is the sheet-metal stack, formed in two thicknesses, riveted upon the outside and inside of C, the smoke-stack ring.
D is a casting located intermediately between the smoke-box A and the ring G.
Certain portions will be designated, when necessary, by additional marks, as D D &c.
The lower face of D is saddle-formed to correspond to the curve of A, and is flanged and bolt-ed around the enlarged hole in A. The upper edge is rabbeted, and matches a corresponding rabbet on the surface of O.
D is an internal lip curving upward. Its upper and inner edge corresponds nearly with the inner face of the stack proper.
D is a lip extending upwardjexterior to D, and reaching considerably higher. The small holes d extend inward through the casting from the bottom of the annular pocket (1 be tween the annular lips D and D".
D is a conical portion of the casting extending upward and inward from the top of the lip D". It is provided with apertures (3 D is a lip extending from the upper and inner edge of the conical portion D downward and slightly outward, as shown. Its lower edge terminates in the pocket (1.
E is an annular ring, which I term a damper-plate, of conical form, and fitting tightly and easily on the exterior of D and provided with apertures e, which when the damperplate is in one position coincide with the apertures d", and allow the air to enter the stack as desired and reduce the draft. The provisions for the exhaust may be of any ordinary or suitable character,and need not be particularly described. Their function is to send the exhaust-steam in vigorous jets into the interrior of the stack. When the damper-plate E is partially turned around on its conical seat D the apertures are brought out of coinci- ICO - desired. All the parts of B being formed in;
dence and all ingress of airthrough .theapertures is stopped. In various intermediate positions the air will beadmitted in various quantities less than the full capacity of the apertures.
' E E are short arms or lugs formed onthe damper-plate E. They receive pins F,which connect with links G, which by pins H connect with a transverse lever, I, turning on a center, J, fixedjon the smoke-box. A link (not represented) jointed to one end of the lever I extends to a point in the vicinity of the foot board, and is operated by the engineer or fireman at will to adjust the damper-plate E from time to time, as required.
COare bolts which connect the ring 0 withf the casting D. Allowance is made forthese; bolts in proportioning and arranging theholes d and. e, as shown in Fig. 3. g
I make the part D of cast-iron and the damper-plate E of brass. The difference inf the expansion of these metals tends to balancei the difference in temperature, so that there? is little derangement of position due to the} expansion and contraction; but the conical, form allows any required amountwithoutin-j. volving mischief. Expansion of thedamperplate relatively to its seat simply allows the; damper-plate to movedownwardon the seat. 1 Contraction simply draws it upward. The} orifices are neverthelesspresented in such po-i sition as to receive the air forcibly from .thej action of wind or from the motion of the locomotive. The inner lip, D, deflects the steam and gases inward, so that they are.directed certainly and smoothly to a point well} within the lips D. The outer lip, 1)", extends upward to such height that water thrownup? by theexhauststeam may be received in the pocket d in quantities without possibilityof flowing outthrough the damper'plate E. The drainfiholes d discharge water slowly from the pocket d, so that no accumulationcan long remain to prevent the inward flow of airwhen one casting, gives great strength and simplicity.

The conical -form of the seat D and the damper-plate E may be varied, being more upright or more level than shown.
Parts of the invention maybe used without the whole. I can turn the da-mper-plateby a single link connecting to one point only onthedamper-plate. Such an arrangement is shown in Fig. .4. I prefer the two links These two connections to the lever I enablethe turning-of the damper to be effected without inducing any lateral istrainon the valve or its seat. oneof the links G is balanced :by the thrust The pull on on the opposite link G; or the openingand closingof theapertures for the admission of air may be effected by any of the various methods in use for opening and closing. orifices.
