'Application November 5, 1936, Serial No. 109,214 4 Claims. (01. 105-206) This invention relates generally to trucks for railway equipment,.and.it is an object of our invention to provide an improved combination of elements so constructed and interrelated as to form a relatively simple and yet exceptionally rugged truck adapted for'an extensible wheel base.
A great many truck frames and arrangements thereof have heretofore been proposed and used in practice, but their construction and interrelation of parts are such that they are not readily or properly adaptable to various wheel base requirements. Trucks adapted to comply with such flexible requirements involve the problem of first providing a suitable structure of the component parts so as to accomplish the extensible feature and then of making the parts of such individual and cooperative strength that a highly rugged truck will result.
Our present invention very effectively, simply and economically overcomesthe above dual problem in a manner that will be more apparent from I the following description of the accompanying drawings in which:
Fig. 1 is a side elevation of a truck embodying our invention;
Fig. 2 is a plan view of substantially one-half of the truck;
Fig. 3 is a perspective of the principal component parts of our invention.
In the particular embodiment of the invention which is disclosed herein merely for the purpose of illustrating one specific form among possible others that the invention might take in practice, we have provided pedestal casting units I and 2 for each wheel and axle assembly. The truck as specifically disclosedis of the four wheel type employing four pedestal castings. Castings similar to I are employed to complete the side of the truck on which casting 2 is disposed, and likewise a casting such as 2 is used to complete the side of the truck on which casting I is disposed. For purposes of this invention, however, it will suffice to describe the relation of parts for only one end of, the truck, it being understood that the other end is identical. Also it will suffice to describe only one of the pedestal castings inasmuch as the castings I and 2 are right and left hand duplicates and hence corresponding parts of the casting will be identified by the same reference number.
Each pedestal casting comprises a wheel piece section 3 having dependent pedestals 4 and 5 which in accordance with usual practice may be provided with pedestal shoes 6. The outer end of wheel piece 3. is provided with an inturned portion I having dependent brake hangers 8 all formed as an integral unit. Also the pedestal 5 has an integral rearwardly projecting end piece support 9, to which a channel end piece II) is secured or cast integrally therewith, if desired. 5 The wheel piece 3 projects forwardly from pedestal 4 for only a sufiicient distance to provide equalizing spring seats I I and. gusset connections located at the inner ends of the wheels as generally indicated at I2 for connection to a transom 1 to be described hereinafter. The gusset has a substantial inwardly extending portion I3 for supporting a transom I4, Fig; 1, on its under side. This portion I3 also functions as a substantial reinforcement for a series of brake hanger lugs 15 I5 and swing bolster link bearings I 6 while a pad I1 with liners I1 is adapted to guide the ends I8, Fig. 2, of a bolster I9. It will be noted that the pad I! and lateral extension I8 are definitely interrelated with the Wheel piece '3 through the provision of a vertical flange 20. The free end 20 of the wheel piece 3 is recessed as at 2I to receive extensible wheel pieces 22 which may be of any suitable length depending upon the desired wheel base of the truck. The recessed end of the wheel piece 3 is extremely rugged and yet compact due to the cooperative supporting relation of the transom gusset I2 and parts associated therewith. Hence upon riveting the extensible wheel pieces 22 to the end portions of wheel pieces 3, an extremely rugged construction is provided. It is, of course, understood that the transoms, extensible wheel pieces and the pedestal portions of the wheel piece castings have rivet holes 23, 24, 25, and 26 to suitably secure the parts and lines I1 35 together. g
With the parts secured together in the manner as above described, it is seen that a truck of substantial character is provided and is adapted to have readily associated therewith the other 40 usual truck features such as the wheel and axle assemblies 30, journal boxes 3|, main equalizing beam 32, equalizing springs 33 and main transverse bolster springs 34. It will, of course, be understood that the length of the main equalizing 45 beam 32 and width of bolster arms I8 and supporting pins 35 journaled in bearing brackets I6, are made to correspond to the individual trucks of various wheel bases in the same manner that the extensible wheel pieces 3 are individually 50 made. However, the remaining integrally cast pedestal portions of wheel pieces 3 will be the same for trucks of all sizes without in any way minimizing or reducing the sturdiness, durability or flexibility of application and at all times re- 55 taining the cooperative action of the transom gusset l2 and flange 20 in supporting the recessed portion 2|,
It will of course be understood that various changes in details of construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as set forth in the appended claims.
We claim:
1. A truck'frame comprising, in combination, integrally cast pedestal units each having a wheel piece, pedestal guides and transom gussets located at the inner ends of said wheel pieces,the inner ends of said wheel pieces being in spaced relation to each other, each of said inner ends having an end slot; intermediate wheel pieces positioned in said end slots between the sides thereof and secured thereto; andtransorns secured to said gussets. N
2. A truck frame comprising, in combination, integrally cast pedestal units eachhaving a wheel piece, pedestal guides and transom gussets located at the inner ends of said wheel pieces, intermediate wheel pieces, and means for securing said inner ends of the unit wheel pieces to the ends of the intermediate wheel pieces so that said inner ends of the unit wheel pieces are in substantial spaced relation to each other, said gussets being formed adjacent to and as part of said inner ends thereby to effect a cooperative supporting relation between the same.
3. The combination set forth in claim 1 further characterized in that said gussets are formed adjacent to and as part of said slotted ends thereby to effect a cooperative supporting relation between the same, and a bolster supporting'bearing is associated with said transom gussets inwardly of the wheel pieces.
4. A truck frame comprising, in combination,
integrally cast pedestal units each having a wheel piece and a pedestal guide, intermediate wheel pieces secured to the inner ends oi'the unit wheel pieces so that'said inner ends are in spaced relationto each other, end bosses projecting outwardly from and integral with the pedestal guides, and an end piece connecting said bosses.
