This invention relates to supports for locomotive accessories.

The object of the invention is to provide novel and improved supports for power reverse gears, air drums, feed water pumps, air pumps and other locomotive accessories, which supports are characterized by simplicity, sturdiness and durability and which fur ther reduce boiler maintenance by the elimination of studs or rivets that are now commonly used in securing the present day form of supports to the boiler.

Referring descriptively to the drawings, the locomotive indicated generally by the designation A comprises an engine bed having side frame members 1. The side frame members are provided in the usual manner with brake hanger brackets 2, having bearing lugs 3. In Figs. 2 and 3 there is illustrated the novel air drum support of the present invention, indicated generally by the designation B. The support comprises a pair of spaced parallel webs 4, having flanges 5 and 6 connecting the webs and disposed at right angles toeach other, the flange 5 having holes 7'for1ned therein, throughwhich bolts (not shown) are adapted to pass, by means of which the support is secured to the frame 1. The flange 6 bears upon and is bolted to the brake hanger bracket receiving support therefrom. The webs 4 are connected along their upper edges by a rib 8. Lugs 9 are formed on the upper part of the support extending outwardly from the opposite sides of the webs 4. Holes 10 are provided in the lugs 9 and the opposite ends of a U-shaped member 11 are passed through said holes and secured by nuts 12. A strap 13 of usual construction, for holding an air drum, is provided at its opposite ends with

eyes

14 and 15. The U- shaped memberll passes through the eye a 14, the opposite end of the strap being disposed between the webs, and a bolt 16 is passed through the eye 15, the oppositeends of the bolt passing through holes 17 formed in the outer-ends of the webs 4, the opposite ends of the strap13 being thus secured to the support. The rib 8 is shaped to provide a substantially horizontal, slightly concave surface 18 and a substantially vertical, slightly concave surface 19 positioned above the surface 18, against which surfaces an air drum 37 is adapted to bear when held'in position by the strap 13. By drawing up on the nuts 12, the strap 13 may be tightened around the drum so as to securely hold the drum in position. As illustrated in Fig. 1, a pair of these supports B with straps 13 are employed to support the air drum 37.

Another form of supporting bracket, indicated generally by the designation 0, is illustrated. in Figs. '4 and 5. This bracket is suitable for various auxiliaries including air pumps, feed water pumps, power reverse gears, and the like. The support 0 is applied to the frame 1 in the same manner as the support B. It comprises a pair of parallel vertical webs 20, joined by a horizontal flange 21 and a vertical flange 22 which flanges are at right angles to each other. The flanges 21 and 22 are provided with

holes

23 and 24, respectively, through which holes bolts (not shown) are adapted to be passed by means of which the support is secured to the brake hanger bracket 2, and the side frame member 1. A rib 25 connects the upper ends of the webs 20 and a vertical flange 26 connects the outer ends of the webs. The flange 26 is provided with bolting seats 27, having holes 28 formed therein for the reception of bolts by means of which an auxiliary (not shown), of the type hereinbefore mentioned, may be secured to the flange.

In Figs. 6, 7 and 8 there is illustrated the combined valve gear support and power re verse gear support shown applied to the locomotive A in Fig. 1. This support, indicated generally by the designation D, comprises a combined power reverse gear support and valve gear support. The valve gear support is the ordinary style of support for a valve gear of the Walschaert type, and is bolted to the cross-ties 29 of the locomotive A, in the usual manner, by bolts which pass through holes 30 provided in flanges 31 which are formed on the opposite ends of the valve gear support. The power reverse gear support comprises an inverted U-shaped plate 32 integrally formed on the top of the longitudi nal member 33 of the valve gear support. Strengthening flanges 34 are formed on the sides of the plate 32.. Bolting seats 35 are provided on one side of the plate 32 and holes 36 are formed in the seats and are adapted to receive bolt-s (not shown), by means of which the power reverse gear 38 is secured to the support. Suitable lugs 39 are provided in the usual manner on guides 40, of the power reverse gear, the lugs 39 having holes 41 formed therein for the reception of the pow er reverse gear securing bolts. A reverse shaft bearing 42 and bearings 43 for the link trunnion of the valve gear are provided in the usual manner, in the valve gear support.

In Figs. 9 and 10 there is illustrated a modified form of the support D'shown in Figs. 6 to 8. The modified support, indicated generally by the designation F1, is of the same construction as the support D except that here the inverted U-shaped plate construction of the support D is replaced by aligned supporting plates or webs 44 which are formed on the upper side of the longitudinal member 33 of the valve gear support. The webs 44 are strengthened by flanges 45, and are provided with horizontal bolting flanges 46. Bolting seats 47 are formed on the flanges 46, and are provided with holes 48, for the reception of bolts (not shown) by means of which a power reverse gear may be secured to the support E.

Referring to the combined valve gear sup port and power reverse gear. support illus trated in Figs. 11 and 12 and indicated generally by the designation F, there is here provided at the right end, a cross-tie member 49 suitably bolted to the side frame members 50 of a locomotive and having a supporting flange for a valve gear support and a reverse shaft bearing, of the usual construction formed thereon. At the other end of the valve gear support the side frame members 50 are connected by a. cross-tie member 51. The cross-tie member 51 is provided with horizontal flanges 52 at each of its opposite ends by means of which the same is bolted to the side frame members 50. A longitudinal strengthening flange 53 is provided on the cross-tie member, and vertical flanges 54 are formed on the outer ends of the cross-tie member for securing the valve gear support 55 thereto. The valve gear'support 55 and the flanges 54 are provided with aligned holes, for the reception of bolts (not shown) for securing the support 55 to the flange. A vertical plate or web 56 is extended upward from the flange 53. The supporting web 56 is provided with strengthening flanges, 57, around its edges. Bolting seats 58 are formed on the web 56, and are provided with holes 59, for the reception of bolts (not shown) by means of which a power reverse gear 60 is secured to said support.

Figs. 11 and 12 show the supporting means applied to a locomotive bar frame type, but the invention is not intended to be so limited and in place of such type, any other type of frame may be employed, as for instance a main bed frame construction and the various parts may be either separately cast or may be integrally cast with the bed frame or other type. 7

From the foregoing description it will be apparent that by the instant invention there has been provided a novel and improved supportingmeans for the various hereinbefore referred to locomotive accessories, which means are characterized by simplicity, sturdiness and durability, while presenting in single unitary structuresmeans for accomplishing what was heretofore accomplished by the use of several separate and independent units. While in the preferred embodiments of the invention the supports will be formed as integral castings, it will be understood that it is within the contemplation of the invention to construct thesame in any suitable manner. Itis further to be understood that while there has been hereinbefore described specific embodiments of the instant invention, many and various changes and modifications in form and structure may be made thereto, without departing from the spirit of the instant invention, and that all and any such changes and modifications that fall within thescope of the appended claims, are contemplated as a part 0 the instant invention. r
