PATENT OFFICE- ONE-THIRD 'ro L. L.
DRAFTING SYSTEM FOR LOCOMOTIVES.
Application filed August 7, 1924. Serial No. 730,656.
To all whom it may concern..-
Be it known that I, WILLIAM L. MoMA- HAN, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Drafting Systems for Locomotives, of which the followingis a specification.
'This invention relates to a drafting system especially adapted to be used upon steam VlOTOIIlOlZlVQS, and it consists in the novel features hereinafter described and claimed.
An object of the invention is to provide r a drafting system of the character stated, in
which is used baffle plates having hinged sections, and a table plate composed of hinged sections, the said sections being provided with screen netting and adapted to hold each other in place in the smoke box of the locomotive, between the steam discharge-nozzle and the stack. 7
In the accompanying drawing:
Figure 1 is a longitudinal sectional view, through the smoke box of a steam locomotive,-with the drafting system applied.
Figure 2 is a transverse sectional view'of the same, cut on the line 2-2 of Figure 1. Figure 3 is a transverse sectional view of the same, out on the line 83 of Figure 1. Figure 4 is a horizontal sectionalview of the drafting system. v
Figure 4 is a fragmentary sectional View of the drafting system, out on the line 4-4 of Figure 2.
Figure 5 is a fragmentary sectional view through the upper portion of the drafting system.
As illustrated in the accompanying drawing, the smoke box of the locomotive is indicated at 1, and the draft tubes 2 of the boiler communicate with the rear end thereof in a usual manner. The exhaust discharge steam nozzle 3 enters the lower portion of'the smoke box 1 and is aligned with the stack 4 which is mounted thereon in the usual manner. Flanges 5 depend from the top wall of the smoke box 1 and are located, one at each side of the stack 4. The said flanges are disposed transversely of, the smoke box. Angle irons 6 are disposed transversely across the intermediate portion of the smoke box 1 and are located one at e'achside of the upper end of the nozzle 3. Table plates 7 are hingedly connected together as at 8, and are provided at their inner edges with recesses 9 adapted'to'register with the upper end of the nozzle 3. The outer edge portions of the plates 7 rest upon the angle strip 6. The screen sections 10 are hingedly connectedtogether as at 11, and are provided, at their upper and lower edges with clips 12 and 13 adapted to engage the flanges 5 and the angle strips 6 respectively. Baffle plates 14: are hingedly connected together as at 15 and provided at their edges with clips 16 adapted to engage the rear flange 5 and the rear cross strip 6. When the products of combustion enter the smoke box 1, they strike the baffle plate 14 and are defle; ted in a downward direction under the table plate section 7 and pass up i through the screens 10, and thusthecinders .areiseparated from the gases and the gases pass up through the stack 4 and are accelerated in their movement by the blast created by the discharge steam emerging from the exhaust nozzle 3;
Having described the invention, what is claimed is: I In a locomot ve, a. draft system comprising an exhaust nozzle leading lnto the smoke box, sectional baflie plates hingedly connected together and provided at their edges with clips, flanges located in the smoke box of tle locomotive, and adapted to be engaged by said clips, table plates hingedly connected together and provided at their hingededges with recesses, said re,- cesses adapted to register with the discharge end of the exhaust nozzle, said table plates adapted to rest upon the flanges in the smoke box, and screen sections hingedly connected together and having at their free edges clips adapted to engage the flanges in the smoke box, the bafi le plates being interposed between the flues and exhaust nozzle of the locomotive, and the screen sections being interposed between the'exhaust nozzle and the forward end of the smoke box. 7
' In testimony whereof I aiflx my signature.
WILLIAM L. MoMAHAN,
Certificate of Correction.
It is hereby certified that Letters Patent No. 1,542,257, granted June 16, 1925, upon the application of William L. McMahan, of Oskaloosa Iowa, for an improvement in Drafting Systems for Locomotives, were erroneously issued to the inventor MoMahan and one-third to L. L, Jordon, Whereas said Letters Patent should have been issued to the inventor, said McMahon, one-third to L. L. Jordon, 0f Oskaloosa, Iowa, and one-third to 0. Rfieott, of Spencer, [010a, as shown by the records of assignments in this oifice; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.
Signed and sealed this 22d day of September, A. D. 1925.
