SPECIFICATION forming part of Letters Patent No. 286,465, dated October 9, 1883.
Application filed September 3, 1883. (No model.)
. citizen of the United States, residing in Pottstown, Montgomery county, Pennsylvania, have invented certain Improvements in Railroad- Scales, of which the following is a specifica tion.
The object of my invention is to prevent the shocks which occur when a car is transferred from permanent rails to those on the platform of railroad-scales-an object which' is attainec'l in the manner fully described hereinafizer.
In the accompanying drawings, Figure 1 is a plan view of part of the platform and frame of ordinary railroad-scales; Fig. 2, the same showing my improvements; and Fig. 3, aperspective view drawn to an enlarged scale, and illustrating my invention.
Referring to Fig. 1, A is part of the platform of ordinary railroad-scales, the mechanism of which is contained within a pit bounded by a quadrangular framework composed of substantial end beams, B, and side beams, D D, the platform carrying rails E E, which are in line with but are necessarily detached from the rails G G of the permanent track.
The platform is supported entirely by mechanism which determines the weight of a car and its contents. tion of the scales may always be assured, there must be gaps d between the platform and the fixed frame, and gaps between the ends of the rails of the platform and the ends of the permanent rails. 7
When a car is transferred from the rails of the permanent track to those of the platform, severe shocks must always occur when the wheels cross the said gaps between the rails, and these shocks must necessarily have a deteriorating effect on the weighing mechanism beneath the platform. In' order to obviate this evil, I bridge the said gaps, in the manner shown in Figs. 2 and 3, by extending the rails E E of the platform beyond the ends of the In order that the proper ac- I same, and beveling the extension a a to coincide with the beveled ends I) of the fixed rails G G. These projecting ends of the rails are never in contact either with the fixed frame by which the pit is bounded or with the permanent rails, for it will be noted on referring to the enlarged view, Fig. 3, that the beam B of the frame, to which is secured the permanent rail G, is cut away at m beneath the pro jecting beveled end of the platform-rail E, so that when the platform is slightly depressed on receiving a loaded car, there can be no fear of the said projecting ends of the rails E coming in contact with the fixed frame. There is also a space of a quarter of an inch, or thereabout, between the beveled end of each platform-rail and the beveled end of the adjoining fixed rail, so as to permit the slight longitudinal play of the plat-form which takes place when a car is transferred from the main rails to the platform-rails.
Vhen the tread of a car-wheel first comes into contact with the projecting end of the platformrail IE, it is not free from contact with the permanent rail G, and hence the transfer of a car from the permanent rails to those of the platform is accomplished without the shocks attending the transfer of the car onto the ordinary platform, as shown in Fig. 1.
In order to strengthen the projecting ends a of the rail E, I secure to it a bar, a, similar to an ordinary splicing-bam'or there may be two of such bars, one on each side of the rail.
I claim as my invention The combination of the platform A of railway-scales and its rails E, having projecting beveled ends a, with the permanent beveled rails G, substantially as set forth.
In testimony whereof Ihave signed my name to this specification in the presence of 'two subscribing witnesses.
