ELECTROMAGNETIC TRACK-BRAKE.
Specification of Letters Patent.
Patented J an. 5, 1915.
Application led July 30, 1914. Serial No. 854,201.
To all whom it may concern Be it known that I, DrEDnRIoH SToRJo- HANN, subject of the King of Prussia, German Emperor, residing at Immigrath, Germany, have invented certain new and useful Improvements in and Connected with Electromagnetic Track-Brakes, of which the following is a specilicatiom reference being had therein to the accompanying drawing.
Track brakes are as a rule applied by means of vertical rods and are either connected together in oppositely arranged pairs by means of special rods or are guided singly by means of a number of rods in separate casings so that the vertical plane of the weight passing through the longitudinal axis is kept iiXed. In this case there is the risk that on the one hand the track brakes can only be applied to a certain gage of track which is very disadvantageous when the gage of the rails is widened. On the other hand, these track brakes cannot adapt themselves to occasional irregularities in the head of the rails.
The present invention takes into consideration the above mentioned defects.
Figure l, is a side elevation of my trackbrake. Fig. 2 is a plan view of the same. Fig. 3, shows a portion of the device including the two non-magnetic screws 13. Fig. 4l, shows a plan of a car truck with connecting rods therein. Fig. 5, is a plan view showing the electric connections. Fig. 6 is a plan View of a car truck, showing a portion of the brake. Fig. 7 is a side elevation of the car truck, with electrical connections.
The track brake shown in Sheet 1 of the drawing suspended upon a spring so as to move freely to one side, has rectangular openings l at both ends (Fig. l), the height of which is designed according to the wear of the brake shoes. Through these openings which are provided on both sides with steel projecting jaws faced with non-magnetic pieces 2 (Fig. 2), are laid the two horizontally arranged rods 3, which when the brake shoes are drawn tightly on to the rails abut against the projecting jaws 2 and operate always in the vertical plane, passing through the center of gravity of the brake shoes. The track brake is therefore not interfered ,with in readjusting the gage and also is adapted to correct occasional irregularities in the head of the rail.
The rods 3 are at the same time so tted that they are either joined by means of the connecting bars 4 of the two longitudinal girders of the vehicle as shown in Figs. 4c and 5 or in conjunction with the rods 6 each longitudinal girder 7 is strengthened as shown in Figs'. 6 and 7 and this serves for bracing the wagon frame.
The rolled track shoes of the profilev shown in Fig. 3 on Sheet l are fastened by arranging that their inner surfaces -ll are placed together'around a prismatic shaped bolt head l2, while their outer surfaces form a wedge which by means of two non-magnetic screws 13 is drawn tightly between the jaws la of the pole casing made correspondingly inclined.
The two non-magnetic screws 13 with the prismatically shaped head which extends down as far as the side jaws 14, serve for drawing the brake shoes up tightly and produce an inclosing metal ring in the horseshoe magnet bent only at one side in order to insure the brake shoe against lateral shocks.
Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is l. In an electro-magnetic' track brake, a body frame, rectangular openings in both ends of said body frame, steel projecting jaws faced with non-magnetic pieces, in said openings, and horizontally arranged rods, which, when the brake-shoes are dra-wn tightly onto the rail, abut against said projecting aws, for the purpose stated.
2. In an electro-magnetic track brake, a body frame, transverse rectangular openings in both ends of said body frame, steel jaws projecting from said openings in said body frame non-magnetic facing on said steel jaws and means to draw the brake shoes tightly upon the rail.
8. In an electro-magnetic track-brake, a body frame having longitudinal girders, rectangular openings in both ends of said body frame projecting steel jaws in said openings faced with non-magnetic pieces and horizontally arranged rods abutting against said projecting jaws.
In testimony whereof I aiiix my signature in the presence of two witnesses.
