Original application filed February 9, 1909,

To all whom it may concern:

Be it kno-Wn that I, JOHN Paaren, ot Schenectady, in the county ot' Schenectady and State of New York, have invented a 5 certain new and useful Improvement in Locomotive Exhaustelfipes, of which improvement the following is a specification. My invention relates to locomotive ein haust pipes which are, in American locomotives of substantially all of the present stand ard types of construction, connected to a bed plate or-cylinder saddles constituting the support of the smoke box, and which oom- Inunieate with, and form the exit passage from, exhaust steam passa-ges formed in said support.

The object ot' my invention is to provide A.simple and effective means whereby a tight ljoint between the exhaust pipe and the bed plate or cylinder saddles may' be readily fmade, and time and labor in handling heavy pipes, be economized.

i The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure l is a vertical transverse central section through the upper portion of a pair of locomotive cylinder saddles and a connected exhaust pipe, illustrating an application of' my invention; Fig. 2, a plan or top view of the joint ring, detached; and, Fig'. 3, a

side View of the same.

My invention is herein illustrated as applied in connection with a locomotive exihaust pipe, l2, having a detachable tip or nozzle, 17, connected to its top. The exhaust pipe may be of any ot' the known types', and is herein exemplified as ol the construction set :forth in an application Yfor Letters lliatent filed by me February 9, 1909, Ser. No. 476,922, of which application one is a division. ln ordinary practice, the exhaust pipe is directly connected to the cylinder saddles, 5, or equivalent bed plate, on which the smoke box, ll, o t the locomotive, is supported, and communicates with ex haust steam passages, 5", cored in the saddles or bed plate, through which and through the communicating exhaust; pipe, the exhaust steam from the engine cylinders is discharged to the atmosphere. it. tight joint between the exhaust pipe and saddles or bed Specieaton of Letters Patent.

plate is manifestly necessary, and this is ordinarily made by grinding, which opera tion, in the case ot largeand heavy exhaust pipes, involves considerable time and labor.

l n the practice of my invention, l provide a separate and independent grinding block or joint ring, 28, which is in the form of a tlat metal plate, the upper and lower faces of which are iinished truly, and which is provided with two passages, 28a, separated by a central bridge, 28, and corresponding in contour Awith the endopenings of the exhaust steam passages, 5a. lhe grinding block may be either otv the same contour as the grinding surface on the saddles or eX- haust pipe base, or be reduced in thickness at and adjacent its periphery, and provided with bolt holes, 28, formed in the portion ol reduced thickness, for the reception of bolts, 2l), which pass through said bolt holes and througli holt holes registering therewith in a circiunferential flange, 12a, formed on the exhaust pipe adjacent to its lower end, and secure the exhaust pipe and the interposed grinding block firmly to the cylinder saddles, 5.

The opposite surfaces ot' the joint ring or grinding block, 9,8, can be alternately and independentlv ground to the bearing surfaces ot the bottom oi the exhaust pipe and of the cylinder saddles. respectively, thereby enabling more perfect joints to be made and eeonomizing time and labor in handling exhaust pipes, which, in many of the latest constructions ot locomotives, are comparatively large and heavy.

l claim as my invention and desire to secure by l'iettors Patent:

l. The.combination, in a locomotive engine, oi a bed plate having exhaust passages termimiting in a seat 'for the exhaust pipe, an exhaust pipe adapted thereto, and a metallic grinding block interposed between said and exhaust pipe.

2. rllhe conlbination, in a locomotive engine, of a bed plate having separated exhaust passages terminating in a seat for the exhaust pipe, an exhaust pipe adapted thereto, and a metallic grinding block having passages registering with the terminals of the cylinder exhaust passages and interposed between said seat and exhaust pipe.

miami 3.`The eembination, in a locomoive en- 1 passing through said Hange of the grinding gine, of a bed plete having exhaust passages block and clamping against the Hnge of the terminating ihm seat for the exhaust pipe, e Hnged exhau t pipe adapted thereto, a peripherzilly flanged metallic grinding blocki interposed between said seat and exhansti pipe, and bolts engaged in said bed plate and exhaust pipe.
