JOSEF I-IILMAR, OF MAGDEBURG, GERMANY.
AUTOMATIC TRAlVlWAYSWlTCH.
SPE(IFICA'JTION.forming` part of lLetters Patent No. 714,301, dated November 25, 1902.
Application filed June 16. 1902. Serial No` 112.009. (No model.)
8 Blumenthalstrasse, Magdeburg, Germany,.
have invented a new and useful Improvement in Automatic Tramway-Switches, of which the following is a specification.
My invention relates to an innovation in a working arrangement for the points of tramway-switches; and its objects are to safely work the points by means of the car, even without being obliged to'decrease the speed. This arrangement can be so safely situated that it can never be disturbed by the traffic of other vehicles and is in its construction, as well as manner of fixing, a very cheap working arrangement.v I attain these objects by the mechanism illustrated in the accompanying drawings, iu which-- v Figure 1 is a schematicalrepresentation of the switch with the new working arrangement; Fig. 2, the working arrangement itself from a top view. Fig. 3 is a vertical crosssection on the line y y of Fig. 2. The left side shows the vertically-placed working wheel and the tongue, the right side a horizontally-placed working wheel, the tongue left away. The connecting-rod lis shown as a broken-od piece. Fig..4 is a longitudinal section of the fragment-piece with the tongue situated inside according to section on the t line a. of Fig. 3.
order to work the points of this switch, I place on the track at a distance of one or` more lengths of a car before the switch-tongues fragments of rail eZ, Figs. 2 to 4,-which are not dierent on their surface from the surface of the other rails, and thus an uninterrupted line of rail isobtained. These fragments of rails are connected to the rails in the usual wayv with fish-plates. The lower part of the rail-groove e in these parts of rail gradually sinks downward from one end f to a certain depth, then runs again horizontally g, and comes up at the other end 7L again to In the deepest part g of the groove lies a tongue t', which can be pushed into a side opening Zr. under the top of the rail. The tongue Z `is pivoted in this opening 7c and its other end may swing horizontally. If the tongue groove.
is moved toward the rail-groove, thenone end remains in the opening while the point touches the opposite side of the deep rail- Thus this deeper part of the railgroove gradually'becomes narrower. For one working arrangement two fragments of rail are'necessary-one in each rail. Bot-h tongues t' are connected with a rod Z, that when one tongue recedes into the opening Zt this causes the other tongue to appear in the deep railgroove. The movement of these combined tongues is to beconveyed to the rail-switch by a suitable arrangement.
In the drawings I have, for example, shown a rod m, bent at both ends, lying in the middle of the rails. The bent ends catch into holes in their respective connecting-rods c Z. The side movement of the working tongues t' takes place by putting in the line-groove any kind of arrangement which by springpressure is pressed downward, slides on the sloping surface f into the deeprail-groove, and presses the tongue sidewise. According whether the right or left line-groove of this arrangement is introduced-the switch Z m c is thus moved. As an arrangement for this purpose the known downward-movable little wheels can be used, or rods 0,-with little rollers p, as shown in Fig. 3. This is not to be a part of my invention, which consists only of the tongue lying under the rail-topv -swinging in the deepened rail-groove and its connection with the switch.
What I doclaim as my invention, and desire to secure by Letters Patent, isl l. In a working mechanism for tramwayswitches two fragments of rail each having its line-groove deepened and a side opening, Vtongues pivoted in said opening and connected to both switch-tongues, all as and for the purpose set forth. g
2. In a working mechanism for tramwayswitches, twofragments of rail each having its line-groove deepened and a side opening, a tongue pivoted in said opening, both tongues connected by a rod catching a double lever in gear with the connecting-rod of the switchtongues, as described and for the purpose set forth.
In witness whereof I have hereuntoset'my hand in presence of two witnesses.
