LATERAL-MOTION 'DRIVING BOX.

Application filed June 25, lees/seri l no.e47,445. 1'

To all whom it may concern: 1

Be it known that I, SAMUEL S. RIEGEL, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented cer tain new and useful Improvements in Lateral-Motion Driving Boxes, ofwhich the following is a specification. My invention relates to lateral motiondevices or equipments for the driving or axle boxes of locomotives and .other railway vehicles, whether associated, with pivot-ed trucks or with rother forms of carriage. While the invention has the same general objects and purposes as the construction shown in United States Patent No. 1,181,194

issued to myself and William Woodard, jointly, on May, 2, 1916 (which exemplifies the lateral motion appliances heretofore, in general use), and is intended to meet the same general conditions, it also presents important distinctions and advantages of its own, as will hereinafter appear; 2

By my present invention, I aim to siniplify and improve such lateral motions; to

cheapen their construction; and to enable them to beeasily applied to locomotives already built, without the necessity for extensive -0r costly changes in such locomotives. How these and other advantages can-be realized in a novel manner through my in.- vention will appear from .my description hereinafter of the best embodiment ofthe In the drawings, Fig. 1 is a fragmentary side view, partly in section (as indicated by the line 11 in-Fig. 8), of a railway vehicle axle and its axle boxes, illustrating the application of my present invention thereto. i v I Fig. 2 is a fragmentary View of the parts at one axle box illustrating the action of the device in service, many of the parts being in section, and the scale being larger than in Fig. 1. i I

Fig. 3 is a view toward one of the wheels from the inside, with certain parts in sec? tion as indicated by the line 3.3 inFig. 1, and still others partly broken away. l

Figs. 4.; and 5yare fragmentary diagrammatic views similar to Figs. 1 and 3', but on a much smaller scale,illustrating the application of my lateral motion. in connection with spring rigging different from that shown in Figs. 1 to 3.

ReferringtoFigsfl, 2 itfwill he boxes in the tion is; shown applied-to a locomotive in connection with the driving. wheels of its than withwheels "of accessory carriages or trucks. The locomotivegside frames illustrated are of the standard bar type, with top rails A,;bottoni railsB, and vertical pedestaljaws forthe vertical movement or play of the driving boxes, D. i The pedestals C may be provided with the usual shoe andwedge means, 6 and/f, or their equivalents, for properlyuguiding and sustaining the driving or axle boxes,D,,"which rest on the axle Gr ofthe drivingwheels H. Except as hereinafter described, theparts D, G and H may be ofstandard orany other suitable. type and construction. [As shown, the outer'and inner flanges c and j ofthe driving boxes D are spaced apart to afford clearance for such lateral movementof the jaws Gas is. required by the locomotive design and the intended conditionssof, service, and the-outer wear faces ofthe boxes afford lateral thrust hearing at is forthe hubs of the drivers. A due proportion of the load of the vehicle eight, etc., isytransniitted to the axle boxes D through the usual spring riggingstructure L, and other parts now soon to bedescribed.

In practice, of course, 0 may be closed at the bottom with the usual pedestal frame hinder or tie, and the usual lubricating and other accessoryparts seenthat in thepresent instance my inventhe pedestal jaws may be provided: these, however, are all omitted from fusion. I I

In the present instance, the load is trans mitted from the spring rigging structure L to the corresponding driving box D at diffe-rent points lengthwise of the axle G, through a saddle 14 with depending leg portions 15, 16 toeither side ofthe top railA'. The clearance between the saddle 14 and the the drawings, to avoid conleg 16 restsand bears a rounded foreanj The shorter innei 10o toprail A permits the saddle to ride up and r of the member 20.

was 20, wa is transmittedto the box Dbfy III means of a member 23 interposed between said member and a part 24 mounted on the box; As here shown (see Figs. 2 and 3), the part 2e has a fore and aft recess in, its lower side to accommodate or take over the inner top flange ofthe box I), and en'- gages or interlocks at 26 (with a i'asonablg; close fit) in? the usual inner fore and a saddle seat 17 just beyond said. flange. [he Qverhangihg'and depending'fportion of the part 24 may be bolted fast-to the box D, as ,shown;

{"In. the present instance, the load-transmitting member23 has the character of a double; "pint rocker, with a long :Eoreand aft pivot back or apex 27' and; double fore and aft pivot feet 28, 29. The a ex pivot 27 engages and b'ears in a corresponding iound 'ed" fore and an seat in the laws side h f the are;nter 20, and the feet28, 29, in similar seats in the aforesaid: part 24;. As here shown, the'seats for the outer toot pivots 28f are directly over the inner end .or side of the box D,

those for the inner foot pivots 29 o erha g eyond t e he l In the presentv instan; e, the construction is all just alike at opposite sides of the carriag i t e Weeds h f l' soi s, d s' tionf appliesto both boxes and their as- SO etedPa rts, L I f 7,, pe a y, s es h I iq e 19 1 tions of the parts'wnen the device is propie rly adjusted and the locomotive is on i 'ii'ghft 2 T e u 6 he w s H, H against the weaif faces 7c, 7;; of the boxes D, D,;; bothQfeet 28, 29 of each member 23 rest solidly in their bearings iii the part 2 1, and

saddles '14, 14 are level; and there are clea ances between the outer and inner axle box flanges 7;, at both sides of the earriage, on theone hand, and thecorrespond shoes and wedges e, ,f,'on theother hand. lf, now, thevehicle takes a curve with the left-haiid; wheel H at the outside, the result.-

' ing'late ial thrust on and from this wheel an shift or displace the left-hand box D inward, to, the right, carr ing with it the lower end of'the'. saddle leg 15 andthe part 2 that eats the rocker feet 28,- 29, andthus rocking the member 23' about its upperturniiig'center at 27 in the member 20; Qwing to 'tlic' initial downward v and outwardincli- VD, D themselves, by means of resistance of the vehicle load, tipping the :saddle 14: proper about the center 17 or 18,

or both. At the same time, the saddle leg 16 will pivot on tilt slightly at 19. As shown, the seat of the saddle 14 is rounded or cambered transversely a t 30-, so as to roll under the spring rigging L, which remains upright. owing to" the shortness of the inner leg'16, the slight tilting of the saddle 14 aboutthe pivotal center at 19 will not cause any appreciable lateral stress or strain in the spring rigging a a As soon as the vehicle passes from the curve to tangent track and the lateral thrust on he look D is thus relieved, the load ac'ting through the sa'cldl'e' leg lththe device 20, and the still oblique member 23 will forcibly return the box I) to its original position.

YVhen the vehiclet-akes a reverse curve, a similar. action will o'ccurat the other side.

Preferably, provision is made for interconnecting the lateral motions at the two sides of the vehicle, so as to bring both into action in resistance'toi lateral displacement oteither axle box D, D. Ashere'sliown, this is done bydirectly interconnecting the bones a cross tie 3 L integral with the parts 24-. lVith such an interconnection, inward movement of either loo-x D will result in outward movement of the other, and in rocking ot the member 23 at the other box on its inner foot 29; l Vith the symmetrical and similardesign andarrangement of the rocker members 28, 23 here illustrated, the action will be similar and cumulative at both sides otthe-carriage for inward deflection of the box D- at either side: i.--e., the load of the vehicle weight will be brought to hear at both's-ide's" in yielding resistance to inward displacement of b-ox D at either side-, so as to return and reeenter the'parts when the displacing thrus't is relieved. f

In order to prevent dislocation of parts when the locomotive is lifted with a crane and the u's'ual load on them thus removed, a lost-m'otion connection may be provided between the tie 3a and each saddle la r. As shown, this comprises an adjustable doublenutted ring bolt 35 hooked over a lug or hook 36"projecting' from the saddle leg 16 and extending through a hole 31 in or adjacentthe end portion 24.

From the fregoing description, it will be seenthat the parts involved in the lateral motion are few and simple, and can be read i'ly manufactured and carried i'n stock as standard equipment. In order to apply such an equipment to an existing loc'oinotive, all that need be done is to remove its saddles; drill and tap its frame membersA and its boxes D in a few places; bolt on the'parts 24 and the guides 21, and place the parts 23 between them; and, finally, put the saddle 14 in place and, if desired, the parts 35, etc. Thus the only parts of theloc-omotive running gear that require replacement or material modification are the saddles.

Figs. 4 and 5 illustrate the general applicability of the invention, regardless of the exact type or form of spring rigging employed. The figures show a spring rigging L embodying the usual type of equalizers Z whose ends are connected to the springs s, and whose middle portions rest on the shoulders aflorded by the notched corners of the, saddle 14. As usual, each of the equalizers Z comprises a pair of interconnected spaced bars,their spacing corresponding to the width of the saddle 14." from back to back of its shoulder notches. It will be observed that the saddle 14 shown in Fig. 4 is also applicable to the spring rigging L of Figs. 1 to 3, with the spring resting directly on the cambered seat 30.
