LOCOMOTlVE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 485,344, dated November 1, 1892. Application filed July 19, 1892. Serial No. 440,480. (No model.)

To all whom it may concern.-

Be it known that I, MATTHIAs N. FoRNEY, of the city, county, and State of New York, have invented a certain new and useful Improvement in Locomotive Engines, of which improvement the following is a specification.

My present invention relates to improved means for coupling locomotive engines and tenders and other railroad-vehicles together, and is to a certain extent an improvement upon a construction which, among other features, is set forth in Letters Patent of the United States Nos. 266,685 and 408,004, granted and issued to me under dates of October 31, 1882, and July 30, 1889, respectively. I do not, however, limit myinvention to the improvement of the plans of construction described in said Letters Patent, as it is applicable without substantial variation to locomotive engines and tenders of other types and to other railroad-vehicles, such as cars.

The principal object of this invention is to provide a system of articulated framing for coupling locomotive engines and tenders together which shall have the capacity of horizontal flexibility to allow the running-gear to adapt itself to the curvature and inequalities of the track and which will admit of the use of fire-boxes of greater width than the space between the wheels and of greater depth than is attainable in such fire-boxes with the ordinary constructions.

A further advantage attained by my present invention is the provision of two systems of framing in the engine and tender of such construction and in such relation to each other as to constitute a substantial safeguard to the men on the engine in cases of collision or derailment.

To these ends my invention, generally stated, consists in a locomotive-engine having frames coupled to a tender by a pair of longitudinal coupling-beams, which are pivotally connected to the engine-frames on each side of a longitudinal center line thereof, and to a transverse bolster-beam, which is centrally and pivotally connected to the tender. Equivalently the bolster may be transposed in position-that is, it may be centrally pivoted to the engineframe instead of to the tender-and the coupling-beams maybe connected to the tender-frame, or two bolstersone connected to the engine and the other to the tender-frameinay be employed, without.

affecting the principle or operative features of the invention. The coupling-beams may be made to support part of the weight of the engine and transmit it to the wheels of the tender, or vice versa.

The improvement claimed is hereinafter fully set forth.

The location of the main frames and axlebearings of a locomotive on the inside of the driving-wheels attains well-recognized advantages; but if they are so placed and a fire-box which is wider than the distance between the wheels is located between the rear drivingaxle and thetender and the framesbe extended so far backward that the tender can be connected to them then the firebox must be placed above them which results in the center of gravity of the boiler being very high or the fire-box being very shallow, or both, and

even then the frames are in the way of the ash-pan. If the rear extension of the frame is carried down so low as not to interfere materially with a wide fire-box, their strength is very much reduced, especially to resist concussions. For these reasons the general method of construction which I have adopted in my prior-recited patents and in my present invention is to locate the main engineframes in the usual position inside of the wheels and to attach to them a transverse beam, which extends laterally outside of and beyond them. In my present invention longitudinal coupling-beams are pivotally connected to the ends of this transverse beam, and these are placed sufficiently far apart to afford room enough between them for the fire box or ash-pan. If a narrow fire-box is used, the coupling-beams may be connected directly to the inside frames. The back ends of the coupling-beams, as already explained, are pivotally connected to the ends of a transverse bolster-beam, which is centrally and pivotally connected to the tender-frame. This affords a multiple-jointed or articulated connection between the engine and tender, which is capable of adjusting itself to any curvature of the track and will permit the wheels to conform thereto. If desired, vertical fiexibilityunay also be given to the framing, so asto permit the wheels of the engine and tender to adjust themselves to vertical inequalities of the track.

In the accompanying drawings, Figure 1 is a diagrammatic side view of a locomotive engine and tender,i1lustratingan application of myin- Vention. Fig 2 is a similar plan View showing the running-gear, frames, wheels, 850., of the engine and tender in the position occupied on a curve; Fig. 3, aside View, on an enlarged scale, showing the parts of the engine and tender which are coupled together; Fig. 4:, a plan view, on a similar scale, showing the rear ends of the main frames, part of the rear driving-wheels and axle, the transverse and longitudinal coupling-beams, the front tendertruck, and part of the tender-frame; Fig. 5, a similar plan of the same parts as are represented in Fig. 4, but showing, also, a sectional plan of the fire-box and a plan view of the supplemental engine-frames and the front end of the tank; Fig. 6,atransverse sectional view through the center of the front tendertruck, looking toward the engine; and Fig. 7, a transverse sectional view through the firebox, looking toward the front of the engine.

The locomotive-engine herein illustrated accords with that set forth in Letters Patent Nos. 266,685 and 408,004 aforesaid in the general features of having its forward portion supported upon a leading-truck 1, its middle portion upon driving-wheels 1 1", and part of the rear overhanging weight of its fire-box, cab, and foot-plate upon the forward truck 7 of an independent tender A. The waist B and smoke-box O of the boiler are located above the driving-wheels 1 1 and leadingtruck 1, the driving and truck wheels varying in number in accordance with the characteristics of the special type or pattern of engine in which my improvement is applied. The main frames 3 of the engine, which carry the journal-bearings of the driving-axles, as already explained, are located between the wheels, and rigid supplemental frames 4, extending from the front end of the engine rearwardly to the tender, are located outside of the driving-wheels, as described in the Letters Patent before referred to. The fire-box 2 is located wholly in the rear of the back driving-axle, a foot-plate 8 and cab 9 being provided in the proper position relatively to the fire-box and being attached to and supported by the supplemental frames. A transverse beam 5 is rigidly secured to the rear ends of the main frames 3, and may also be attached to the supplemental frames. The front truck 7 of the tender A is shown as provided with four wheels 7 which may vary in number, as desired, and is located below the foot-plate and cab 9, as set forth in the Letters Patent before referred to. A vibrating bolster-beam 10 is pivotally connected to the center pin or king-bolt 6 of the front tender-truck 7, so as to be adapted to turn freely about said pin as a center, or, if preferred. the bolster may be pivotally connected to some portion of the tender-frame, or, as before stated,it might be connected to the engine-frame. The ends of the transverse beams 5 and 10 are coupled together by longitudinal coupling-beamsv 11, which are connected to the ends of the transverse beams by single or double pivotal joints 12 13, so that they can move freely about their points of connection. If horizontal movement only of the coupling-beams is required, singlepivoted joints only are needed for their connections; but if it is desirable that these beams should also have the capacity for vertical movement about their pivots what are known as universal or double-pivoted joints may be employed. The transverse and longitudinal beams are made of proper strength to resist the transverse, tensile, and compressive strains to which they will be subjected in service. By referring to Figs. 2 and 4,thelatter showing an enlarged plan of these beams, it will be seen that the longitudinal coupling-beams can vibrate freely about their front pivotal connections 12 and that the rear ends of these beams have the capacity of movement transversely in the arcs a a, and also that the bolster-beam 10 can vibrate freely about the king-bolt 6, or the pin by which it is coupled to the tender or tender-truck frame, as a center, its ends then movingin the longitudinal arcs b b. I It will be obvious that with such a connection of the engine and tender frames the driving-wheels and the front tender-truck will be entirely free to adjust themselves to any curvature or horizontal configuration of the tracks. This system of construction is also applicable to tenders which have no trucks,

but which are carried by wheels and axles mounted directly on the tender-frame and which have no capacity for horizontal movement relatively thereto.

In Letters Patent No. 266,685 aforesaid a plan for supporting part of the weight of the overhanging fire-box, cab, foot-plate, &c., on the front tender-wheels was described. The construction proposed therein involved the support of the rear ends of the supplemental frames on the front ten der-truck, and the supplemental frames were rigid throughout their length, lateral flexibility being obtained by giving the support on the front tender-truck lateral swing motion. In order to move the rear end of the engine laterally on a curve, the inertia due to its weight had to be overcome by the action of the flanges of the front wheels against the rails. The pressure exertedagainst these flanges by the rails acted on the front end of the frames, the flange of one of the driving-wheels forming a fulcrum at the rail about which the engine turned. With this plan of engine the force which was required to be exerted to move the engine laterally was therefore exerted at the front end of the frame which formed the short arm of a lever. This force was resisted by the Weight attached to the rear end of the engine-frames which formed the long arm of a lever. To overcome the inertia of the weight at the rear end, a con- IIO and to push the front end toward the outside.

The lateral force exerted at the front end was increasedby the relative proportion of the two ends of the lever by which it was transmitted from the rear end. These objections are due in great partto the distance between the rear driving-axle and the bearing which sustains the overhanging weight of the rear part of the engine and transmits it to the tender-truck an d to the consequent amount of leverage and lateral movement of the truck and this bearing relatively to each other in running on a curved track. In order to obviate these objections, instead of locating the bearing for the support of the overhanging weight on the tendertruck or over the tender-wheels, as described in the Letters Patent aforesaid, I provide under my present invention two bearin gs, which are located about midway between the ends or connections of the coupling-beams. This shortens the distance from the rear drivingaxle and lessens very materially the effect due to the leverage of that distance, and also reduces the relative horizontal movement of the parts in contact at the bearing-points, as it will readily be seen from Figs. 2, 4, or 5 that the lateral motion of bearings on these beams in relation to other parts of the engine is less the nearer they are located to the rear axle. To provide for this lateral motion in running to and from curves, either frictional bearings are provided, or preferably the overhanging weight is supported by swing-links, which are connected to the coupling-beams and to the back part of the engine, thus allowing the latter to move freely in relation to the beams. The overhanging weight is supported by the coupling-beams and part of it is transmitted by them to the front tender-wheels. To illustrate this construction more clearly, a portion of the longitudinal coupling-beam 11 on the righthand side of the engine is indicated as broken away in Fig. 3 in order to show the manner in which the firebox is supported on the beams 11. Vertical posts or supports 16, which are most plainly shown in Figs. 3 and 7, are bolted through flanges 17 to the mudring 18 at the bottom of the fire-box 2. Swinglinks 19 are pivotally connected at their lower ends to the lower ends of the posts 16 bypins 20, the upper ends of the links 19 being similarly connected to the longitudinal couplingbeams 11 by pins 21. The weight of the firebox and of the back part of the engine is thus transmitted by the swing links 19 to the beams 11, and at the same time the lower ends of the links are free to swing in the arcs o c, Fig. 7 about their upper pivot-pins 21 as centers. The fire-box is thus free to move laterally independently of the couplingbeams, and as the upper ends of the links 19 are free to swing in the arcs cl (I about their lower pivot-pins 20 as centers the coupling-beams 11 are free to move laterally independently of the fire-box. To insure greater stability, the posts 16 are connected together at their lower ends by a transverse tie-rod 24, Figs. 5 and 7. It will be seen that while this construction affords fully adequate support for the firebox it also permits the frames, wheels, and the connections of the engine to adjust themselves with entire freedom to horizontal or vertical inequalities of the track. Ifdesired, springs may be interposed between the support of the fire-box and the coupling-beams 11, in order to provide an elastic bearing, which would afford a more perfect adjustment of the-engine and tender to vertical inequalities of the track.

More particularly when springs are used between the fire-box and the coupling-beams the latter should be connected to the transverse beams by universal joints of suflicient strength to .resist the tractive force of the engine and the concussions to which the couplings of the engine and tender will be subjected. Suchuniversaljoints,whichareshown at 12 and 13 in the drawings, I make, preferably, of heavy wrought-iron or steeldisks,having a vertical trunnion at the top and another at the bottom, which are held in suitable bearings in the transverse beams. The couplingbeams are then connected to these disks by horizontal cylindrical pins, which latter form the axes for any vertical movement of the coupling-beamsthat may be required, while the trunnions of the disks form the axes for the horizontal movement of the beam.

The supplemental frames are extended in rear of the fire-box and, as before stated, support the foot-plate and the cab. As shown in the drawings, they are not intended to have direct support on the tend er-truck; but, if desired,a bearing maybe provided which would permit a part or all of the weight carried on the back ends of these frames to reston the tender-truck.

In the construction of an engine in accordance with my invention the transversebeams 5 are preferably formed double-that is to say, composed of two connected bars, one of which, as shown in Fig. 7, is placed above or on top of the main frames and the other below them. The upper and lower bars are suitably strengthened by intermediate braces, which are not shown in the drawings. The transverse or bolster beam 10 of the front tendertruck is also preferably composed of two bars with interposed bracing, as shown in Fig. 6, the king-bolt 6 passing through both bars. The longitudinal coupling-beams. 11 are composed of two channel-bars, with plates riveted i so to their top and bottom flanges, and the channel-bars are bent so as to be farther apart at the middle of their length than at their ends, in order to give room between them for the suspension or swing links 19, as well as to give greater capacity for resisting strains and shocks of compression.

In addition to the advantages before stated, the construction herein described affords materially-greater protection than heretofore to the men who run locomotives in the event of collision or derailment. It is well known that one of the most frequent causes of injury and loss of life to locomotive runners and firemen is that theyare crushed between the engine and tender in collisions or when these run off the tracks. My improvement affords a double safeguard against accidents of this character by providing two systems of framing, one above the other, each having the capacity of resisting shocks in collisions.

The main or under tender-frame 25, as shown herein and in my Letters Patent be fore referred to, may be made of metal or wooden beams, as in ordinary practice. The center plate 26, Fig. 6, to which the front tender-truck 7 and the transverse bolster-beam 10 are connected, is secured to the under tenderframe, which is shown in the drawings as composed of metal channel-bars and is of a form beanis l1. All these members are made of great strength and have a corresponding capacity to resist shocks resultant upon collisions or derailments. The rear ends of the supplemental frames 4 are united by an end or tail brace 27, Fig. 5, which is strengthened by diagonal braces 28. The foot-plate 8 is bolted or riveted to the supplemental frames and adds materially to their capability of resistance to shock. In addition to the lower tender-frame 25, as ordinarily employed, I provide an upper or supplemental tenderrame 29, Figs. 2 and 3, which is shown as composed of wooden beams, but may, if preferred, be of metal. The supplemental tenderframe extends from the rear end of the engine to the rear end of the tender, and its longitudinal beams 29 are united by substantial transverse timbers 3O 31 at their ends, the forward transverse timber 30 being provided with a buffer or chafing plate, which abuts against a corresponding plate on the tail-brace 27 of the supplemental engine-frame at, as seen in Figs. 2, 3, and 5. These longitudinal and trans-. verse timbers are securely fastened to the lower tender-frame, thus having great capacity for resisting shocks due to collisions, and by their position transmitting such shocks to or from the supplemental frames of the engine. This system of upper or supplemental frames thus has, independently of the lower or main frames, capacity for resisting strains frequently mount upon or override thatof the engine, and in so doing crush the engine-attendants. In the construction hereinbefore described it will be seen that the supplemental engine-frames overlap the lower tender-frame, and that therefore if the tender should be forced upward it would carry the engine with it, or if the engine should be raised it would take the tender with it. As an additional means of securing this result, I attach guards 32 to the rear part of the engine-frame, or, as shown, to the rear of the fire-box which is connected to said frame, said guards being made to engage with the tender-frame, so that the engine would carry the tender-frame up with it in case of a collision. The construction described therefore reduces in averylarge degree the liability of overriding of engines and tenders, as compared with the ordinary practice, and in this particular affords a material safeguard in cases of collision or de- 'structon, without departure from the principle or essential characteristics of my present invention.

I claim as my invention and desire to secure by Letters Patent 1.
