. UNITED STATES PATENT OFFICE.
' CHARLES a zonnn, or rHoENIk, AnizonaQ nn'ILnoAn-cRossINe.
To all whom it may concern:
Be it known that I, CHARLES A. ZoBEL, a citizen of the United States, residing at Phoenix, in thev county of Maricopa and State of Arizona, have invented new and useful Improvements in Railroad-Crossings, (Case B,) of which the following is a specification.
This invention relates to improvements in railroad crossings, the principal object of the invention being to provide means for preventing the wheels of the train passing along one track from contacting with the rails of the cross track.
The present invention is an improvement over that shown in the application filed by me on Dec. 13, 1919, Serial No. 344,759, which has since matured into a Patent No. 1,347,431, dated July 20, 1920, one of the objects of the present invention being to simplify the arrangement of parts so as to make the opera tion more simple and to reduce the cost of manufacture.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of a crossing constructed in accordance with my invention.
Fig. 2 is a side elevation.
Fig. 3 is a section on line 3-3 of Fig. 1.
Fig. 4 is a section on line 4-4 of Fig. 1.
Fig. 5 is a section on line 55 of Fig. 1.
Fig. 6 is a longitudinal sectional view on line 66 of Fig. 1.
In these views A indicates rails of one track and B the rails of the cross track, the two tracks being shown as single, though it will of course be understood that such tracks may be double. The track A has its rails slightly lower than the rails of track B and the rails of said track A are continuous while those of track B are formed in sections with their ends adjacent the rails of track A. Said ends may have their upper portions cut-away to prevent the'wheels of the train passing along track A from contacting with the rails of track B. A bed plate 1 may be located under the crossing to support the rails. The
' Specification of Letters r teni. Patent d J' fly 5, 9 Application filed November 9, 19205 Serial No. 422.949. i
spaces I formed by theilc'ut-away portions the rails of track B are bridged by the bridge pieces 2 whichare pivoted-tothe bedplate by means of thebolts 3. These bridge pieces are each provlded with an inclinedend for engaging the inclined end of each of the .intermediate sections of track B,;Wl1i0h .lie between the rails of track A and the other ends of sa1d bridge pieces are rounded to engage rounded portions of the rails of track B on opposite sides of track A.
A cross arm 4 is secured to the lower end of each of the bolts 3 and a spring 5 has its ends connected with the arms of each pair of bridge pieces, said springs holding the bridge pleces in position bridging the gaps between the sections of track B.
A pair of rock shafts 6 are arranged between the rails of track A and each of these shafts has apair of crank arms 7 thereon which are connected by links 8 with the arms 4 of the bridge pieces at oneside of track A. The outer ends of these rock shafts 6 carry the off-set portions 9 on which rest the cross pieces 10 which are carried by the pressure rails llwhich are placed parallel to the rails of track A and are adapted to be engaged by the wheel flanges and depressed by the welght of the train. These pressure rails are normally held in raised position by means of the springs 5 acting on the bridge pieces and through these bridge pieces on the rock shafts by means of the bars 8 and arms 7.
It will thus be seen that normally the track B is completed by the bridge pieces bridging the spaces between the sections of the rails so that the wheels of the train can pass over the rails of the track A without touching them. When atrain travels along track A, however, its wheels will engage the pressure rails 11 and depress the same so that the rock shafts 6 are rocked by the pressure of the cross pieces 10 on the offset parts 9 and this rocking movement will cause the bridge pieces to swing inwardly toward each other by means of the arms 7 and connecting rods 8 acting on the cross pieces 3. This will permit; the wheels ofthe train to pass along. track A without engaging the rail of track B. As soon asthe wheels leave the pressure rails the springs will return the'parts to normal make changes in the construction and in the combination and arrangements of the several parts, provided that such changes fall Within the scope of the appended claims.
What I claim is 1. A railroad crossing having one track in a higher plane than the other track, said higher track having cut-away portions leaving spaces for receiving the lower track, pivoted bridges for said-spaces, cross arms connected with said bridges, spring means for connecting the cross arms for each pair of bridges together so as to hold the bridges in closed position, rock shafts, crank arms therein, links connecting the armswith the cross arms and means for rocking said shafts by a train on the lower track.
2. A railroad crossing having one track in a higher plane than the other track, said higher track having cut-away portions leaving spaces for receiving the lower track, pivoted bridges for said spaces, cross arms connected with said bridges, spring means for connecting the cross arms for each pair'of bridges together so as to hold the'bridges in closed position, rock shafts, crank arms therein, links connecting the arms with the cross arms and means for rocking said shafts by a train on the lower track, such means consisting' of pressure rails arranged parallel with the main rails of the lower track, cross pieces connecting said rails together and offset arms on the rock shafts engaging "said cross pieces.
In testimony whereof I affix my signature.
CHARLES A. ZOBEL.
