vThis invention'relates to locomotives and more particularly to articulated locomotives ofeither the single expansion or the compound type. a a
By myinvention aim to reduce the overhang of the boiler of such a locomotive, and to maintain the center of gravity of the boiler morenearly over the center of the wheel base .a longitudinally of the locomotive and also more nearly over the center of the wheel base transversely of the locomotive when it is taking curves.
Another object of the invention is thereduction of the length of the steam connections to the various operating cylinders.
A still further object of the invention contemplates reducing the size of certain of the steam connections, particularly those which ,must be provided with universal or flexible joints, and thereby permit such joints to be of smaller dimensions and consequently more readily packed and maintained tight.
The invention contemplates further the accomplishment of the foregoing objects by the employment of a novel frame and driving wheel construction which makes possible the above and other advantages.
How the foregoing together with other objects and advantages are obtained will be 30' clear from a consideration of the following description and the accompanying drawing.
In the drawing, Figs. 1a and I?) placed together at their lines w-a: form a somewhat v diagrammatic side elevation of a locomotive embodying my 1mprovements.
Referring now particularly to the drawing, the locomotive boiler is indicated by the reference numeral 2. This boiler, it will be seen, is mounted above two frames, the forward of which is indicated at 3, and the other at 4. These two frames are articulated together by the connection indicated at 5' and the forward frame is provided with bearer means 6 for the locomotiveboiler which per- 'mit lateral movement relative thereto. The
boiler 2 is, of course, rigidly secured to the rear frame member 4.
A cylinder 7 is provided on each side of the locomotive for driving the set of wheels 8 in the rear group and these cylinders are rigidly secured to the boiler Qand the rear,
frame 4. A set of cylindersv 9 are secure d to I the movable frame 3 and serve to drive the wheels 10 of the forward group. The steam 2;
connections are arranged in such manner that both of the pairs of cylinders are supplied with live steam. They receive their supply from the dry pipe 11 and the cylinders'ilexhaustthru the pipe 12. A pipe 13 communicates withthe steam. chest of cylinders? and serves to carry'steam from the cylinders I'Z forwardly to the cylinders 9. lilxhaust pi pes 14: are also provided for the-cylinders. 9; These connections 13 and. 14,190 the cylinders:
on the movable frame 3 are provided with flexible connections 18 at their ends.
If desired the two pairsof cylinders may? becompounded, I f I :Abooster; motor 15 may be applied to the," trailing truck 16 as shown in the-drawing, or it may be appliedto the pilottruck 17 or,"
' if desired, such motors-may be applied-to idly secured to the frame carrying the larger group there will be a relatively smalliboiler' overhang. This arrangement also brings all the cylinders nearer tothelp'oints on the 10*CQ', motive boiler to which the live steam and 8 X,
ha-ust-pipes from the cylinders must lead (it e.v
the dry pipe and the smoke box) Thus these steam connections are reduced in length and losses due to radiation are reduced to a mini Q mum.- Such an arrangement alsojip'ermitsthe cylinders for the small and relatively movable group of drivers to be madeof smaller dimensions as they are required to drive only: a relatively small group 'ofwhcelsJ, Qons efi quently the diameter of the steam connections to the cylinders 9 may be made, relatively small and their flexible joints of correspond ing dimensions and therefore fv'ery "readily and effectively packed against leakage.
7 vided a locomotive of the articulated type which materially and effectively reduces the boiler overhang as well as heat losses due to radiation and leakage of the steam connections.
I claim 1. In an articulated locomotive having a total of not less than eight pairs of main driving wheels, a main frame having six pairs of the main drivers mounted therein, and a supplemental frame articulated to the main frame and having other pairs of main drivers mounted therein, the number 7 of pairs of drivers mounted in said supplemental frame being less than the number mounted in the main frame.
' 2. In an articulated locomotive having a total of eight pairs of main driving Wheels, a main frame having six'pairs of the main drivers mounted therein, and'a supplemental frame articulated to the main frame and havin the other two pairs of main drivers mounte therein.
3. In an articulated locomotive having a total of eight pairs of main driving Wheels, a main frame having six pairs of the main drivers mounted therein, and a supplemental frame articulated to the main frame and having the other two pairs of main drivers mounted therein, together with a single ex pansion driving engine "for each group of drivers includlng relatively large capacitycylinders for the larger group and relatively.
small capacity cylinders for [the smaller 'group With relatively large and small size steam connections for the large and small cylinders, respectively.
4;. In an articulated locomotive having-a total of eight pairs of main driving wheels,
' a main frame having six pairs of the main drivers mounted therein, and a supplemental frame articulated to the main frame and havmg the other two pairs of main drivers mounted therein, together with a single expansion driving engine for each group of drivers ineluding relatively large capacity cylinders for the larger group and relatively small capacity cylinders for the smaller group with relative.- ly large'and small size steam connections for 'the large and small cylinders, respectively,
the supply connection for the small cylin-- ders being extended between those of the two actuating the driving wheels in the main" frame; a source of steam supply andla' point of exhaust steam disposal located 'on the boiler between the two sets of cylinders; relatively large size but short steam connections e31 tended between said source and said point of disposal and the relatively large cylinders; relatively small size and short steam supply and exhaust connections for said relatively small size cylinders; and correspondingly small flexible joints for the steam supply and exhaust connections last mentioned; whereby the boiler overhang and losses due. to leakage and radiation from the various steam connec tions are maintained at a low value.
In testimony whereof have hereunto signed my name.
