UNITED STATES PATENT OFFICE.

GHAUNCEY DARRAH ALLEN, or rononro, ONTARIO, AND CHARLES EDWARD BROOKS, or MONTREAL, QUEBEC, CANADA,

LOCOMOTIVES TUB/BET,

Application filed July 26, 1923.

To all whom it may concern:

Be it known that we, CHAUNOEY DARRAH ALLEN, a citizen of the United States, and a resident of the city of Toronto, in the county of York, in the Province of Ontario, Canada, and CHARLns EDWARD BRooKs, a subject of the King of Great Britain, and a resident of the city of Montreal, in the Province of Quebec, Canada, have invented '10 certain new and useful Improvements in retis so constructed that the threaded connection between the turret valves and the turret body is dispensed with, in which the valve discs may be ground or changed without removing the valve bonnet, in which the operating mechanism extends from that face of the turret facing the cab, and the outlets for the pipe connections are located on the opposite face of the turret or away from the cab toward the front of the locomotive, in which easy accessiblity is provided to permit uncoupling or removing the steam pipes without disturbing the operating valves or their connections in any Way, in which means are provided for altering the length of the turret body to suit the boiler connections and to accommodate the turret so as to conform to the contour or lateral curvature of the boiler, in which free movement of the turret bodies crosswise of the boiler to allow for expansion and contraction is provided for, and a free up and down movement, and a free rotary movementbetween the two faces of the turret body is also provided for, but not free to rotate frontwards or backwards on the faces connected to the boiler, and it consists essentially of the arrangement and construction of parts hereinafter more particularly explained. i

In the drawings like characters of reference indicate corresponding parts in each figure.

Fig. 1 is a side elevation of a boiler of a locomotive indicating the rear end of the boiler and cab of our turret, shown in con- Serial No. 654,039

nection therewith, parts being broken away and in sections to exhibit the turret in elevation.

Fig. 2 is a plan view of the parts shown in Fig. 1.

Fig. 3 is an enlarged detail shown partly in elevation and partly in section of our turret.

Fig. 4 is a plan view of the parts shown in Fig. 3, with a portion of the boiler and cab supporting our turret.

Fig. 5 is a perspective detail of one form of filler piece or block.

Fig. 6 is a similar view of another form of block.

Fig. 7 is-a sectional plan detail of the connection between the turret sections. Fig. 8 is a plan view of the parts shown in Fig. 7.

1 indicates the cab of the locomotive, 2 a boiler, 3 the roof, and 4 the front wall of a cab in which are located a series of orifices 5 arranged in horizontal alignment and spaced suitable distances for a purpose which will hereinafter appear.

6 is the body of our turret which is divided into two sections 6 and 6 in which are formed chambers 7 and 8. These sect-ions 6 and 6 are provided at their inner ends with outwardly extending flanges 9 and 10 (see Fig. 8) connected by bolts 11 thereby making a unitary structure which extends crosswise of the top of the boiler as clearly indicated in Figs. 1 and 2 at the outside of the wall 4.

A connection between the turret sections 6 and 6 is formed by the flanges 9 and 10. The flange 9 of the section 6 is provided at one end with a complete orifice and at the opposite end with an open-ended slot ex tending vertically. The flange 10 of the section 6 is provided with an open-ended slot extending vertically and located opposite the complete orifice of the flange 9, and at the other end of the flange 10 is provided a complete orifice opposite the open-ended slot ofthe flange 9. The bolts 11 extend through these complete orifices and openended slots of the flanges 9 and 10 so as to connect the parts together.

In order to alter the length of the turret body to suit the boiler connections we have provided a filler piece or block such as indicated at X which piece or block is of any desired uniform thickness or in order to accommodate the pitch of a turret body to the contour or lateral curvature of the boiler the filler piece may be made wedgeshaped as illustrated in Fig. 6. Flanges 9 and 1,0 are forthis purpose also, provided each with a complete orifice X and with an open-ended slot or notch X This connection also permits of a slight rotary movement between the end faces of the turret sections.

12 and 13 are steam pipes extending from the boiler each provided at its upper end with an annular 14: having bolt orifices 15 therein. An annular seating flange 16 extends around the pipe orifices. An orifice 17 is formed in each section 6* and 6 and from which depends an annular flange 18 provided at its lower end with an annular seating portion 19 to bear against the portion 16' hereinloetore referred to.

20 is-a flange provided with notches 21.

22 are bolts, theheads 23 of which fit into the notches 21 of the flange 20, the shanks of the bolts depending through the notches 2liandthrough the orifices 15, provided at their lower ends with securing nuts 23. The internal face of each flange is recessed as. indicated at 24 to receive an annular valve seat 25. i

26 is. an orifice formed in the upper wall ot'each turret section 6 and 6 in vertical alignment. with the orifice 17.

7 isa valve cap provided with ing portion extending into the orifice 26 and provided with outwardly extending flanges 98" having a tapered top portion 28.

29 is a ring member provided with a taper 29 fitting the tapered portion 28 through "which extends bolts 29 securing the-same to the top of the turret.

30'is valve stem which is threaded in thecap 2.7 according to usual practice and provided with a handle 31 at its upper end, the valve head 32 at its lower end coacting with the annular seat 25. By this means the supply of steam into the interior a depend- ,of ourv turret chamber is controlled.

33 are. orifices formed in the front wall of: each section 6 and 6 and 34 orifices in alignment with the orifices 3'3 and tormedfin the rear wall or each section 6 and .6;

35 are nipples fitting in the orifice 32 and provided with annular flanges 36, the outer faces of which are tapered as indieated at .37.

38 are annular rings having internally tape-red portions fitting the tapered portiQDSfiTL:

39 are securing bolts by which the rings are connected to theturret body. By this means. the nipples 35 are securely held in place. The inner. portion 0t each nipple is provided with an annular s at 40.

4 15 is a valve cap or bonnet. A valve cap. or bonnet is secured in each. orifice'33 by means similar to that described in connection with the nipples 42 are valve stems held within the oriiices 33. The valve stems 4-2 are divided into two partsv 42 and -12" connected to gcther by universal joints l3 intermediately between the wall l of the cab and the turret body. Each valve stem portion 1-2 extends through the orifice '5 and is provided at its inner end with a controlling handle 44.

By this construction each valve may be removed from its valve stem l2 without removing the cap or bonnet l1 and the valve seats removed for grinding.

It will be seen by this construction also that the controlling valvehandles of the turret are arranged in crosswise align ment within the cab so that they can be r adily gotten at by the operator and any one picked out for n'ianipulation. It will also be seen by the above construction that the turret being located outside of the cab and the pipe connection on the outside of the turret or toward the front ofthe engine or away from the cab there is absolutely no danger of the occupants of the cab beingscalded due to the leakage or from any other cause. y

In order to protect the turret we have provided a housing 45 comprising an arch portion 46 torn'ling an extension of the cab roof 3 and the portion 4-7 hinged to the portion 4-6 as indicated at 48. The free end of each portion 47 rests upon the top of the locomotive boiler.

From this description it will be seen that we have devised a very simple construction by which the turret may be located ex tcriorly oi the cab. in which the valves n re arranged so as to be easily manipulatwl by the operator within the cab, in which the steam connections are at the outside ol the turret away from the cab so that there will be no danger of the operator being scalded, in which are provided means where-- by the adjustment of the valves may be made directly without the loss of time incidental to the adjusting of the valves heretofore experienced in turrets hitherto devised, in which simple means is provided whereby the turret may be adjusted to suit the boiler connections of any locomotive and also may be readily adjusted to contl orm to the lateral curvature of the boiler. in which easy accessibility in uncoupling or removing the steam pipes without dist-urli-ing the operating valves or their connections in any way is provided, and in which the grinding or changing of the valve discs without removing the bonnet from the turret casting is provided.

hat we claim as our invention is:

I; In a locomotive turret, the combination with the boiler, of a turret extending crosswise of the boilernnd divided into two sections to form separate steam chambers, a steam supply duct leading from each chamber and supporting each section, means for connecting the inner section ends together adapted to permit free movement between the adjacent end faces without tendency to horizontal rotary movement upon the aforesaid section supports.

2. In a locomotive turret the combination with the boiler and cab wall, of a turret extending cross-wise of the boiler and divided transversely into sections, a spacing block interposed between the adjacent ends of the sections, bolts carried by the block and engaging the section ends to permit free movement between such ends in all directions except simultaneously in the same horizontal direction.

3. In a locomotive turret, a turret body divided into two sections and means interposed between the adjacent ends thereof to vary the position of the sections longitudinally to align its connections with differently located boiler connections.

4. In a locomotive turret, a turret body divided into two sections, and means for securing the adjacent ends of the sections together to permit the pitch of the sections to conform to the boiler curvature.
