Original application filed August 18, 1921, Serial Ilo. 493,299,
Divided and this application filedliiarelr 2, 19532.
To all whom it maybonccrn:
Be it known that I, ALFREDWV. Pinuon, a
citizen of the United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful Improvement in Lateral-Motion rip-- pliances for Locomotive Driving Boxes, of which improvement the following is a spec-- ification.
The object of my invention is to provide means for affording and controlling lateral motion in the driving boxes of locomotive engines,which shall be of simple and inexpensive construction, and of ready applicability in locomotives oft-he various present standard types, with the result of enabling a locomotive, having a comparatively long rigid wheelbase, to pass through curves of comparatively short radius, without liability to derailment, and without inducing undue or excessive wear of wheel flanges and rails.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawings: Figure 1 is a view, in elevation, of a locomotive frame pedestal, with an axle and driving box in vertical transverse section, illustrating an application of my invention; Fig. 2, a vertical central section through the same; and, Figs. 3 and 4, views, taken similarly to Figs. 1 and 2, respectively, illustrating a struc tural modification.
In the practive of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, and first to Figs. 1 and 2, the driving boxes, at, adjoining the driving wheels, 6, which are fixed on opposite ends of the driving axle, 8, are provided with the usual ournal bearings, 4, and oil cellars, 4, and are fitted in the pedestal jaws, 3, of the side frame members, which connect the upper and lower frame rails, l and 2, thereof, between wedges, 4 and shoes, 4 in the ordinary manner. The open spaces between the sections of the lower frame rails, 2, are spanned by pedestal ties, 5, suitably connected to the lower frame rails.
The portion of the weight of the locomotive which is carried on the driving axle, 8, is transmitted to the driving boxes, at, through springs, 9, which bear, centrally, on seats, 10, at the ends of a rigid yoke or spring supporting beam, 10, extending transversely of the locomotive, and adapted to move vernow Patent No. 1,414,455, dated May 2, 1922.
Serial No. 545,715.
tically, but not laterally, relatively to the side frame members. it will, of course, be understood that the springs are connected, y banners at e r ends, to the side frame members, either directly or through the intermediation of equalizers, in the ordinary manner. The spring supporting beam. it), is guided, in its vertical movements, by guide lugs, 10*, projecting downwardly from its body, and adapted. to fit, with easy working clearance, against the upper frame rails, l, or rubbing plates secured thereon.
The ends of the supporting beam, 10, are supported upon the driving box'esyl, through the intermediation of vibratable rockers, which are. of bell crank or elbow link form, and comprise a plate, 11, extending vertically, adjacent to the inner side of the upper frame rail, 1, and having an upper arm, 11, and a lower'arm, 11. The rocker is coupled to the spring supporting beam, 10, by a" pin, 12, passing through the rocker, at the junction of the plate, 11 and its upper arm, 11 and the lower arm, 11", of the rocker, is recessed to bear on a roller, 12 fitting in a central transverse groove or recess in the top of the driving box, -l. The spring support ing beam, 10, bears on the outer end of the upper arm, 11, of the rocker.
In the operation of a locomotive engine in which a construction embodying the essential features of that above described, or their equivalents, is applied, when one of the driving wheels is laterally deflected, in either direction, from its normal position, relatively to the adjacent side frame, which deflection is effected by the resistance opposed by the contact of the outer track rail with the flange of the adjacent driving wheel, upon the passage of the locomotive from a tangent to a curve of the track, the accompanying lateral movement of the driving box, swings the rocker, 11, in direction similar to that of the movement of the box. This movement of the rockers which acts to raise the supporting beam, 10, is resisted by the weight carried by the ad jacent end thereof, this resistance acting, through the pin, 12, and roller, 12, and being determined by the angularity of a line connecting the axes of these members. The beam, 10, being prevented from moving laterally, the springs, 9, participate in its vertical movement, as the resistance stated is overcome, without disturbance of their relation, laterally, to the side frame members or equalizer connections.
In the construction illustrated, the resistance is exerted on one side of the locomotive only, the journal at the opposite end of the axle sliding through its driving box without instituting any resistance other than lateral journal friction, which, if the journal is properly lubricated, will be trifling. As the resistance of the rail decreases, in the passage of the locomotive from a curve to a tangent of the track, the super imposed weight on the rocker, forces the driving wheel out to its normal position, and the load is again carried on all three bearing points of the rocker, as indicated in Fig. 2. v
The structural modification shown in Figs. 3 and 4t, complies, in all essential particulars, with the construction above described, difiering therefrom only in the form of the rocker, which, in this instance, is a plate, 11 having a segmental bearing, 11 on its lower end, fitting in a correspondingly curved central transverse groove or recess in the top of the driving box, l.
The rocker, 11, is coupled, at its top, to the beam, 10, by a pin, 12 and its outward swing is limited by lugs, 10, on the downward extensions of the beam, 10, adjacent to its end.
The operation of this specific form of my invention in entering and passing from acurve of the track, is similar, in all essential particulars, to that of the construction shown in Figs, 1 and 2, and first above described.
I claim as my invention and desire to secure by Letters Patent:
1. In a locomotive engine, the combination of a side frame; a driving box, fitted, with the capacity of relative movement, therein; a spring supporting beam, which is vertically movable, relatively to the driving box; a link rocker, interposed between, and bearing on, the driving box and the supporting beam; and a pin, coupling said rocker to the supporting beam.
2. In a locomotive engine, the combination of a side frame; a driving box, fitted with the capacity of relative movement, therein; a spring supporting beam, which is vertically movable, relatively to the driving box; a bell crank link rocker, interposed be tween the driving box and the supporting beam, and having arms bearing on said members; and a pin, coupling said rocker to the supporting beam.
