PATERSON, NEW JERSEY.
SPECIFICATION forming part of Letters Patent No. 318,708, dated May 26, 1885.
Application filed August 23. 1884. (No model.)
.To all whom it may concern:
Be it known that I, SAMUEL H. DUNNING, a citizen of the United States, and a resident of Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Exhaust Mechanism for Locomotives, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
This invention relates to devices whereby the exhauststeam is diverted at will into or away from the draft-outlet of the smoke-stack in order to control the draft.
The said invention consists in certain im provements in such devices, which will be hereinafter described,and pointed out in the claim.
Figure 1 shows my invention in elevation. Fig.2 is a plan of the same. Fig. 3 shows the interior of the smoke-box and arrangement of devices, the smoke-pipe being shown in section, and Fig. 4 is a part view of a locomotive in elevation having a part of my invention attached.
A represents a blast or exhaust device for a locomotive, having pipes a and b. The pipe a is provided with a screw-thread at the top of the same, and connects by means of a coupling, a, with a pipe, a arranged in the smoke-stack O, and one on each side of the interior of the smoke-stack, as shown in Fig. 3. The nozzles 12, which are inverted in position, are arranged in the bellshaped mouth of the pipe F, above which pipe is suitably ar ranged and secured a like pipe, F, said pipe being centrally located in the smoke-pipe, as shown in Fig. 3. The valve-stem it, which is arranged in a case, b, is provided with a piv 0t, b, and passes through a covering-plate, d, which plate is secured by bolts d d d on the stem h. Behind the covering-plate at there is arranged a valve or diaphragm,h, which valve is provided with valveseats g g on the outer end of the stem h, and secured thereon by a screw-nut, e, is a tapering arm, e. The opposite end-of the arm is linked to a crankarm,f, by means of a link, f, and pins f. The crank, of which the arm f 2 is a part, is pivoted within the smoke-box B on a pivot-stud, f The arm f of the crank passes through a slot, 19, arranged in the smoke-box therefor,
and connects with a bracket-lever, f pivoted on astud, f, arranged on the smoke-box B. The bracket-lever also connects adj ustably with an operating-lever, f by means of a link, f. The leverf which is provided with a handle, L, is adjustably secured to the floor in the interior of the cab, as shown by dotted lines, Fig. 4. The flangek is provided with bolt-holes k, and may be secured in position in the smoke-box by bolts. The steam-pipes E E are arranged as shown. The cylinders H, boiler N, and cab are arranged in the usual way. In practice the engineer or fireman from this position in the cab can, by means of the operatinglever f and the connections herein described and shown, have perfect control of the exhaust, blast, 830., and can regulate the same without resorting to the fire-box door in the usual way, securing more perfect combustion and saving of fuel by this my invention, as the currents may be discharged through the pipes a and sparks may be prevented from passing through the nozzles 12. The valve h may be held in any position desired by pins arranged for the lever f.
I am aware that it is not broadly new to provide the smoke-stack of an engine with a bifurcated exhaust-pipe, one branch of which discharges into the stack to create a draft, the other branch discharging outside of the stack, the steam being directed through one or the other branch, as desired. This, therefore, I do not broadly claim.
What I do claim as new, and desire to secure by Letters Patent, is-
The bifurcated exhaust-pipe a b, in combination with a pipe, at, extending from one of its branches, a, to the open air, a bell-shaped nozzle, F, into which the other branch, 1), discharges, a valve, f, which directs the steam to one or the other of said branches at will,rockshaftf, aIlDSf f f connecting rod or link f, and lever or handlef pivoted in the cab, in order that the engineer may control the draft of the engine through the devices aforesaid, substantially as set forth.
