SPECIFICATION forming part of Letters Patent No. 490,539, dated January 24, 1893.

Application filed August 29, 1892. Serial No. 444,376. (No model.)

.To @ZZ whom t may concern.-

Beit known that I, CHARLES CAMP, a citizen of the United States, residing at Chicago, iu the county of Cook and State of illinois, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification. Y

This invention relates to attachments to be applied to locomotive and other boilers to prevent the emission of smoke, and consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The obj ects of my invention are first, to provide a device for the prevention of smoke, which may be applied to any kind of a boiler, and which shall be inexpensive in construction, simple and effective in operation; and second, such a device which will produce au artificial draft, and by reason of the same, will facilitate the generation of steam.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1, is a view in side elevation of the boiler, fire-box, and a portion of the cab of a locomotive, with my attachments in place ready for operation. Fig. 2, is a view in front elevation thereof. Fig. 3, is a detached plan view of the controlling valve of my invention. Fig. 4, is a central sectional View thereof, taken on line 4, 4, of Fig. 3. Fig. 5, is a central cross sectional view, taken on line 5, 5, of Fig. 4. Fig. 6, is a perspective View of a combvalve or piston, employed in the lower portion of the controlling valve. Fig. 7, is a horizontal sectional View of a portion of the fire-box, steam pipe, and one of the injectors connected thereto. Fig. 8, is a vertical sectional'view of a portion of the steam pipe, which is located Within the smoke stack, With its thimble and smoke conductor or sleeve, employed to produce an artificial draft. Fig. 9, is a view in side elevation of-a plug to be used in connection with the controlling valve, when the same is to be operated indirectly. Fig. 10, is a sectional view thereof, showing a portion of the conducting pipe secured thereto.

Fig. 13, is a View in side elevation of the controlling Valve, showing a modification in the manner of operating the same. Fig. 14, is a plan view of the valve, connected with the boiler, showing a modification in the manner of operating the same, in connection with the throttle lever` of a locomotive. Fig. 15, is a view in front elevation thereof. And Fig. 16, is a sectional view, taken on line 16, 16, of Fig. 7.

Similar letters refer to like parts throughout the different views of the drawings.

A, represents the boiler of a locomotive of the ordinary construction, having the smoke stack A', steam dome A2, fire-box A3, cab A4,

-and the other usual appurtenances, to the head of which, andv preferably to the valvegage or what is termed by engineers the pumpkin B, is connected and receives steam therefrom, the controlling valve C, which valve is made of any suitable size, form and material, but preferably of the form shown in Figs. 3, 4, and 5. The upper portion of said valve is formed or provided with a holloW screw threaded projection c, which is adapted to be inserted into or connected with the front portion of the boiler A, or the pumpkin B,the hollow c', thereof, opening into a slightly enlarged and longitudinal cavity C', which is located about the central upper portion of the valve C, and has leading laterally and transversely therefrom two ports C2, which unite with vertical channels C3, C4, which channels are open at their lower ends, and the former one C3, has connected to it a conducting pipe D3, which conveys steam from the valve to the smoke stack, and for the purpose presently to be explained.

To the lower end of the channel C4, is connected in any suitable manner a conducting pipe D4, which passes around'the fire-box A3, and is provided With a number of steam jets or injectors for the distribution and discharge of air and steam, into said box, to facilitate the draft therein. As is clearly shown in Fig. 4, of the drawings, the front end of the cavity C, is formed with a screw threaded plug E, the open end of which is provided with suit- IOO able packing E2, through which is passed a valve-stem E', having on its inner portion suitable male screw threads e, to engage with the female threads e', to regulate the valvehead E4, which is secured on the inner end of the stem E', and opens or closes the hollow c', leading to the cavity C. The outer ends of the ports C2, are likewise provided with screw threaded plugs C5, having suitable packing E5, in their outer ends, through which are passed the valve stems E6, provided with male screw threads e2, on their inner portion s, and with valve heads E7, on their inner ends, which heads open and close the channels or ports C2, as is apparent by reference to Fig. 5, of the drawings. Near the lower ends the ports or channels C3, and C4, are formed with hollow bosses F, which are threaded on their inner surfaces and are provided with threaded plugs F, having suitable packing F2, th rough which is passed valve stems F2, having on their inner ends the Valve heads F4, to open and close the channels G, which are united vertically with the cavity C', and laterally with the ports C3, and C4.

As shown in Fig. 4, the lower middle portion of the cavity C', may be formed with a funnel-shaped opening as at c2, while its upper central portion is provided with an opening c3, having a removable plug c4, which construction permits of access to the interior of the valve, so that its parts may be lubricated, as well as ailording a channel or guide-way for the steam from the cavity C', to the cavity H, which is located longitudinally and directly beneath the cavity C', and is provided at its front end with a screw-threaded hollow plug h, having at its outer end suitable packing h', through which packing and plug is passed and operates a rod or stem H', having secured to its inner end a comb-toothed piston or valve H2, which operates in the cavity H, and is provided at a suitable point with two vertical orifices or openings I, which are separated by an upright partition I', and are provided with vertical ribs, or comb-teeth t', and receives steam from the cavity C', and discharges it into the channels G. The front portion of the stem H', is formed hollow and provided with internal screw-threads t0 engage with the rod H3, which has at its outer end a milled hand-piece 71,2, for turning the same, and is screw-threaded on its inner portion to engage with the hollow of the stem I-I, thus forming a turn-buckle to adjust the length of the stem or rod to levers having different distances to travel. The top and front portions of the piston or valve H2, is provided witha pin or projection i', which tits into a longitudinal groove t2, in the upper surface ot' the cavity H, and prevents the valve turning as is obvious.

From the above, it will be seen and readily understood that when the steam is admitted to the cavity C', through the hollow c', and the ports C2, are closed it will pass down through the funnel-shaped opening c2, of the cavity C', into and through the openings I, oi' the piston or com b-valve H2, out into the channels G, and from thence into the ports or channels C3, C", which are connected with the conducting pipes D3, and D4, respectively, and that the volume of steam will be divided by the partition I', of the comb-valve as well as regulated by the comb teeth t', which arc placed in the openings I, for this purpose. For it is apparent, that when a tull supply of steam is desired to pass through the openings I, they maybe placed directly under the opening c2 ot' the cavity C', and when a smaller quantity is desired, the piston or valve may be moved forward by means of the lever, when the port will be partially closed and the steam will pass between the comb-teeth 7l, or by moving it farther forward the entire supply may be shut off. The front portion of the rod Il, is provided with a laterally extending pin or projection h4, which fits into a vertical slot h5, of the bar K, which is pivotally secured at its upper end to a horizontal brace rod K', which is provided with a longitudinal slot 7s, through which is passed a screw k', and adjustably secures it to the top of the controlling valve. The lower end of the bar K, is pivotally secured to the throttle-stein L, which is operated by means of the throttle-lever L', of the locomotive.

As shown in Figs. l, 2, and 4, ot' the drawl ings the conducting-pipe D3, is secured to and is united with the lower end of the channel C3, and passes down and under the running board m, and then vertically into the smoke-stack A', to nea'r the top thereof. At suitable points within the smoke-stack the pipe D3, is provided with a number of perforations or holes CZ, through which the steam may escape into a truncated-cone M,which surrounds the pipe D2, and is tightly fitted at its bottom to said pipe' just below the openings CZ, therein, and has its walls a slight distance from the pipe and in alignment therewith to near its top, when the same are inclined inwardly, as at fm. Around this cone is placed and secured a sleeve N, which has a Haring opening or mouth u, at its bottom, and an enlargement or chambern, which is contracted at its top just above the upper part of the cone M. It is apparent that when the steam passes through the pipe D3, and escapes into the cone M, it will pass therefrom through its contracted openingm, with great force and will create a vacuum in the sleeve N, into which the smoke will rush and be commingled with the steam in its passage through the smoke-stack, thus causing additional draft throughout the boiler.

To the lower end of the channel C4, is secured the conducting pipe D4, which passes around the fire-box A3, and is provided at proper intervals with a number of injectors or jets O, through which steam and air is forced into the fire-box. These jets or injectors are constructed of a hollow screwthreaded thimble O', having a flaring mouth IOO ITO

o, to receive air, and a small pipe @which is connected at one end. with the pipe D4, and has its other end inserted into the hollow of the thimble as is clearly shown in Fig. 7. The inner portions of the pipe p, is provided with a screw-threaded enlargement p', which is provided Withlongitudinal groovesp2, through which the air may pass and mingle with the steam.

In Figs. 9, and 10, I have shown a plug P, which is designed to be used in connection with the controlling valve C, when it, the valve, is so located that it must receive steam indirectlyfrom the boiler. When such is the case, the end c, of the valve C, is formed'with screw-threads to receive the threaded end r, of the plug P, which plug is formed, as shown, with a dead end r', which may be screwed into the boiler at any suitable point, and a pipe P', connected at one of its ends to the steam-dome or other suitable point to receive steam from the boiler, may be attached at its other end to a boss P2, on the plug P, having a channel r2, connecting with the hollow r3, of the plug which when in position opens into the cavity C', of the controlling valve.

In Figs..1l, and 12, I have shown a modification of my controlling valve, which is somewhat simpler in construction than the valve C, which has just been described, and consists of a cylinder C5, having a cavity C6, about its central portion, and one of its ends formed or provided with a hollow screwthreaded projection c5, which is adapted to be inserted. into the boiler and to convey steam therefrom to the cavity C6, and its other end provided with a hollow screw-threaded plug C7, having suitable packing c6, through which packing and plug is passed a stem or rod E8, having on its inner portion screw-threads e8, to engage the threads e9, and on its inner end a valve-head E9, to open and close the hollow of the projection c5, and to admit or shut olf the steam from the cavity C6, into which opens the channels or ports D7, D8, and which extend laterally from said cavity. The outer ends of these ports or channels are provided with hollow screw-threaded plugs D9, having suitable packing D10, through which is passed valve stems D11, having on their inner portions screW-threads d8, to engage threads dg, and on their inner ends valve-heads D12, to open and close the ports which open into suitable bosses D13, on their under sides, which connect with the conducting pipes D3, and D4, in a similar manner and for a like purpose above described. It will therefore be understood that this modilication is designed to be operated without a lever, while the first described valve is adapted to be operated with a lever, or automatically in the movement of the saine.

In Fig. 13, is shown a modification in the manner of operating the valve C, which consists in placing on the top of the valve a quadrant-brace S, having a number of depressions s, to engage with the grip-lever S', of the operating lever S2, which is slotted longitudinally as at s', to receive the pin h4, on the rod H3, and which lever is fulcrumed at its lower end to a brace-rod S3, which is secured to the bottom of the controlling valve.

Figs. 14,and 15, illustrate another modification in the manner of operating the valve, when attached to a locomotive, in which a brace-rod T, is secured to the valve, and has pivotally secured to its free end a rod T', which engages with the stem H3, and is pivotally secured at its other end to the throttlestem U, which is secured to the throttle-lever W, which may be fulcrumed to the free end of a brace-rod W', attached to the boiler.

The operation ofgmy device is simple and as follows: The valve is attached to the boiler at any suitable point, to receive steam therefrom, but preferably directly with the pumpkin. The steam is then admitted to the cavity C', by opening the hollow c', by means of the valve-head E4, when, if it is desired, either one or both of the channels O2, may be opened, and the steam discharged into the pipes D3, D4, respectively, and from thence into the fire-box or smoke-stack or both. Or both the ports C2, may be closed, when the steam will pass through the opening c2, into the orifices I, of the piston or comb-valve H2, and thereby be divided and regulated, into the channels G, from one or both of which it may be discharged into the -pipes D3, and D4, by opening the channels G, by means of their valve-heads.
