ATTACHMENT FOR FURNACES.

Specification of Letters Patent.

Application filed January 26, 1916. Serial No. 74,399.

To all whom it may concern:

Be it known that I, ENOCH J. KUBIQHEK,

a citizen of the United States, residing at Horton, in the county of Brown and State of Kansas, have invented certaln new and useful Improvements in Attachments for Furnaces, of which the following is a specification.

My invention relates to furnaces and has for its object the provision of a simple apparatus which may be easilyapplied to any furnace and by the use of which the smoke and soot usually accompanying the kindling of fires and the replenishing of fuel thereon will be eliminated.

A further object of the invention is to provide a device for the stated purpose which will be simple in construction and, therefore, easily renewed or repaired and which will be found efficient in operation and economical in production and maintenance.

' The several stated objects and such other objects as will incidentally appear in the following description are attained in such a device as is illustrated in the accompanying drawings and the invention resides in certain novel features which will be particularly pointed out in the claims following the description.

In the annexed drawings: Figure 1 is a view partly in transverse section and partly in end elevation showing a steam boiler furnace having my improved device applied thereto; Fig. 2 is a vertical longitudinal section of the same; Fig. 3 is an enlarged detail vertical section of my improved attachment; Fig. 4 is a detail perspective view of a portion of the attachment.

In carrying out my invention, I secure in the wall of the furnace at a point which will be in communication with the ash pit, a casing 1 which may be of any suitable durable material and which is preferably of metal. Preferably, the casing is secured in the side wall of the furnace just below the grate bars, as shown in the accompanying drawings, although it may be applied at other points, and the casing may be of any desired dimensions or shape as may be necessary to conform to the particular construction of the furnace to which it is applied. The inner and outer sides of this casing are open and near the inner side thereof, I secure across the casing a partition or support 2 which is provided with a number of openings in which are secured the tapered nozzles 3 which are so disposed that their smaller ends will be directed inwardly to the ash pit. Between the partition or sup-' port 2 and the outer end of the casing 1, I provide partitions or supports 4: which'are spaced apart to admitair into the outer wider ends of the nozzle 3 and in the said partitions or supports 4, I secure a plurality of nozzles 55. corresponding in form and construction to the nozzles 3-, and each axially alined with one of the nozzles 3. It will be easily understood that, when the nozzles are axially alined, the smaller end of the outer nozzle will be disposed adjacent the larger end of the inner nozzle and preferably will extend into the inner nozzle, as shown clearly in Fig. 3 of the drawings. Upon the front and rear sides of the casing 1, adjacent the lower end thereof, I secure brackets 6 in which are mounted the ends of a supply pipe 7. The ends of this pipe are closed by suitable caps or otherwise and preferably the pipe is constructed of two members united at their inner ends by a T-coupling 8 which also receives a member of the main supply pipe 9 which extends to the steam space of the boiler and may be equipped with a cutoff valve 10*. The supply pipe 9 isconstructed of a series of alined members con-v nected by couplings 10, as will be readily understood and passes through a loop or retainer 11 secured upon the top of the casing 1 at the outer side of the same. Each coupling 10 is disposed in the plane of'two Patented Dec. 119, 1916.

alined nozzles 3 and 5 and the branch supply pipes 7 leading from the couplings are each constructed with a plurality of jets 12 which are axially alined with adjacent nozzles and extend into the outer ends of the same, as clearly shown. A coupling 13 is disposed immediately above the loop or retainer 11 so as to connect the adjacent sections of the main supply pipe and this construction will permit the lower portion of the main supply pipe, with all the branch pipes extending therefrom, to be; swung downwardly about the brackets 6 as a pivotal center so as to permit access to all the jets and to all the nozzles should it be necessary to repair, clean or renew the same.

he uses and advantages of my device are thought to be manifest from the foregoing description taken in connection with the accompanying drawings. The fire is kindled and fuel placed thereon in the usual manner.

The draft through the fire will create a suction through the nozzles 3 and 5 which will draw fresh air into the ash pit whence itwill rise through the grate and the bed of the fire, supplying the necessary oxygen thereto jets 12 and pass through the nozzles 5 and 3 into the ash pit, the flow of said steam from said nozzles creating a strong suction which will draw in a full supply of air so that the fire will quickly be brought to a white heat and the production of smoke overcome. By the use of my device, soft coal and finely comininuted fuel may be used advantageously so that the supply of steam may be maintainedat a very low cost.

Y The device is obviously simple in its construction and may, therefore, be produced at a very low cost and expeditiously and inexpensively applied to any furnace. Owing to its construction, all the jets and nozzles are readily accessible so that the necessary repairs or all cleaning can be very quickly and conveniently effected. This invention or apparatus may be made any size with any number of nozzles and may be used for other purposes where a large amount of air is needed, such as in blacksmith shops, as the force of steam through the nozzles is very powerful and, therefore, takes the place of the .power fan.

Having thus described the invention, what is claimed as new is: V

1. An apparatus for the purpose set forth comprising a casing adapted to be secured in a furnace wall, a partition in said casing, a plurality of tapered nozzles secured in and extending through said partition, the outer ends of said nozzles having the greater diameters, a plurality of supports within the casing spaced outwardly from said nozzles and spaced from each other in a transverse plane of the casing, a plurality'of tapered 'nozzles secured in and extending through said supports and each alined axially with one of the first-mentioned nozzles with its inner smaller end fitting concentrically within and in spaced relation to the outer end of the same, a supply pipe disposed at the outer side of the casing and extending across the same, a plurality of branches extending laterally from the supply pipe'across the outer ends of the outer nozzles, jets on said branches each extending into the outer end of one of said outer nozzles, a retainer at the top of the casing and extending laterally therefrom to fit around the supply pipe, and brackets extending laterally from the lower end of the casing and in which the lowest branches are j ournaled whereby to pivotally support the supply pipe and all its branches and permit the same to swing from the casing.

2. An apparatus for thepurpose set forth comprising a casing adapted to be secured in a furnace wall, a plurality of axially alined nozzles supported within said casing, brackets at the lower end of the casing extending laterally therefrom, a central retainer at the top of the casing projecting laterally therefrom, a steam supply pipe having a vertical main portion extending across the end of the casing and a plurality of branches extending laterally across the end of the casing, and jets on said branches extending into'the outer ends of the outer nozzles, the lowermost branches being pivotally mounted in the said brackets and the main supply pipe passing through-and held by the said retainer.

In testimony whereof I afl'ix my signature.
