The present invention relates to a steam locomotive installation including a main steam locomotive boiler and an auxiliary boiler or boilers mounted on a single rigid frame member as well as modifications thereof involving an interconnected plurality of frames and bogies in which the weights of said boilers are suitably distributed over these members.
The invention is particularly an improvement over prior arrangements and apparatus of this class as applied to such apparatus as shown in the U. S. Patent No. 1,682,006, for example, wherein are found articulated steam locomotives comprising two or three distinct units, all or some of which are driving units and each or which has a rigid frame and is connected with another.
The accompanying drawings show by way of example some embodiments of the invention, ap-
0 plied to locomotives of known construction as disclosed in the mentioned patent, hence,-
Figures 1 and 2 constitute a side view of a steam locomotive having a single rigid frame type, and having a steam generating boiler and 25 an auxiliary boiler.
Figures 3 and 4 constitute a side View of a locomotive including a generating boiler mounted on a main rigid frame, with two auxiliary boilers supported on two auxiliary frames hingedly 30 connected to the main frame, the whole weight of the frames being carried by two bogies.
Referring now again to the drawings, Figures 1 and 2, G is a rigid frame on which a main steam generating boiler is mounted, comprising 35 a fire-box l1 and two drums I8, while H are the two bogies on which are individually mounted the two auxiliary boilers l9 connected to the end of the two drums l8 by two flexible conduits serving for the passage of the hot gases. The
40 bogies H, which are arranged below the frame G, are connected thereto by a connecting system 2| which transmits to said bogies H the whole weight of the frame G as well as the weight carried on the latter.
In Figures 3 and 4, I is the main frame on which a main steam generating boiler, including a fire-box 22 and two drums 23, is mounted. To the ends of the frame I are connected, by horizontal pivots 24, two auxiliary frames L which 50 are capable of independent vertical movements and on which the auxiliary boilers 25 are respectively mounted, said auxiliary boilers being connected to the end of the drums 23 by flexible conduits 26-serving for passage of the hot gases, 55 While M refers to two bogies suitably arranged under the frames I and L. The two pivots 21 serve to connect the main frame I to the two bogies M and to transmit to the bogies M the whole weight of the main frame I, the weight carried on the latter, a portion of the weight of the auxiliary frames L and a portion of the weight carried on the latter. The two slides 28 merely serve to transmit to the bogies M the remaining portion of the weight of the auxiliary frame L as well as the remaining portion of the weight carried on the latter that has not been transmitted through the pivots 21. The application of the pivots 21 and slides 28 may also be reversed at will with respect to the frames I and L.
It is to be understood that in the locomotives described and illustrated in Figures 1, 2 and 3, 4, water tanks may be mounted on the upper frame or on the bogies.
As the invention is not directly concerned in any case with the actual construction and oper ation of the fireboxes per se for the boilers, nor the means of access thereto, such details have been omitted to clarify the views, especially as the necessary features thereof will occur to anyone skilled in the art when carrying out the invention.
Having now fully described my invention and disclosed in what manner the same is to be practiced, I claim:-
1. In a steam locomotive installation provided with a main steam boiler heated by the gases of combustion from a firebox, said main steam boiler having two steam collecting drums, two auxiliary steam boilers of smaller individual capacities than the main steam boiler, flexible conduits of smaller diameters than said boilers interposed between said main steam boiler and the auxiliary steam boilers in order to carry the hot gases of combustion from said main boiler to said auxiliary boilers so as to heat the latter, a main frame supporting said main steam boiler, and a pair of spaced bogies individually located beneath and supporting the ends of said main frame and also individually supporting said auxiliary boilers, there being a plurality of axles supporting said bogies and having wheels thereon.
2. In a steam locomotive installation provided with a main steam boiler heated by the gases of combustion from a firebox, said main steam boiler having two steam collecting drums, two auxiliary steam boilers of smaller individual capacities than said main steam boiler, flexible conduits of smaller diameter than said steam boilers interposed between the main steam boiler and the ondary frames connected by means of horizontal pivots to the ends of the main frame and supporting said auxiliary boilers, and slides disposed on said bogies which, together with the horizontal pivots, support the weight of said secondary frames and. said auxiliary boilers.
