BOGIE FOR RAILWAY CARS AND THE LIKE.
Application filed July 16, 1926, Serial No. 122,748, and in Sweden July 20, 1925.
This invention relates to improvementsin bogies for railway cars and the like, in which the load is transmitted by springs to a beam or the like supported by the journal boxes, the springs being placed in vertical recesses in the beams and compressible by means of a bolt or the like.
7 The object of the invention is to secure the parts from being damaged and to, improve designs of the said kind generally.
The invention consists, chiefly, in the bottoms .of the recesses being provided with a projecting sleeve adapted to receive the bolt head and having such. a length as to entirely embrace the bolt head in every position of the same. thread, the core diameter of which is at least as large as the bolt shank, said bolt being enclosed by a nut of about the same height as the thread, by which the bolt is held protected against damage-during running.
In the drawing, a form of embodiment of the invention is illustrated by way of example. Fig. 1 is a section of the beam 2 isa side elevation of the beam with the spring support. Fig. 3 is a plan view of the beam at the recess. Figs. 4: and 5 are side elevation and plan view, respectively, of the lower washer.
Referring to the drawing, the beam 3, through the intermediation of a spring 4, carries the bogie frame 5. The spring l is placed in a suitably cylindrical recess 6 in the beam 3 and bears with its lower end on the bottom of the recess. This'bottom may be fixed, or it may consist of a removable washer 7. The spring 4 bears at its top on a washer 8, abutting against a bracket 1 'fastened to the bogie frame. When using a removable bottom washer 7 (a through-going opening in the beam), the washer 7 is suitably provided, at its edge, with recesses 9 cor responding to shoulders 10 in the opening of the beam, thus providing a bayonet-lock for the washer 7. Furthermore, this washer 7 can suitably be provided with downward projections 11 (Fig. 4:) fitting in recesses 13 in the shoulders 10 in the opening ofthe beam, said shoulders forming supporting edges preventing unintentional turning of the washer. The Washers 7 and 8 are pro- The bolt is fitted, at its top, with a,
vided with central holes. By this means the spring can be compressed bysorewing the washers towards each other by means of a screw 12, the mounting being thus exceedingly simple and convenient, since the spring, after having been compressed, can be inserted'and removed with the washers as a unit.
According to the invention, the bottom of the recess, or the washer 7, is provided with a projecting sleeve 15, serving to receive the bolt head 14 and having such a length as to effectively embrace the bolt head at any time, when it is in action. By this means, the advantage is gained that the bolt head will never pass beneath the bottom edge of the beam. Moreover, the bolt need not be removed from the bogie duringrunning.
The bolt 12 is fitted, at its top, with a thread, the core diameter of which is at least as large as the bolt shank, said bolt being enclosed by a nut 16 of about the same height as the thread, whereby the same will be securely protected against damage during running.
In compressing the spring for dismounting the parts, the nut 16 is turned so that the bolt 12 is raised until the bolt head 14 bears on the inner top surface of the projecting sleeve 15. By this operation, the nut 16 is screwed down over the bolt shank, which is made possible by the core diameter of the threaded part being at least as large as the bolt shank. The bolt is prevented from turning with the nut, the portion 17 of the bolt shank next to the bolt head 14 being square and formed so as to fit in a corresponding square hole 18 in the upper bottomof the sleeve. When further tightening the nut, the spring 4: will be compressed between the washers 7 and 8 and, thereby, unloaded, whereby it becomes free and can be removed from the bogie.
We claim:
1. A bogie suspension device. For hi l in which the load is transmitted by springs to a beam, supported by the journal boxes, the springs being placed in vertical recesses in the beams and compressible by means of a bolt, characterized by the respective bottoms of the recesses being provided with a proj ecting sleeve serving to receive the bolt head and having such a length as to effectively emnull, of about the same hoighhas the threaded part, suhstantlally as and 101' the purpose set forth.
In testin'lon T whereof We have si ned our llillllQS.
