Application filed January 30, 1917. Serial No. 145,487.

To all whom it may concern? Be it known that I, GEORGE L. FORESTER,

a citizen of the United States,residing at Asheville, in the county of Buncombe and State of North Carolina, have invented new and useful Improvements in Switches, of which the following is a specification.

The present invention relates to improvements in means for bridging the gaps be tween the frog and the main and siding rails at a railway siding, whereby the wheels of the rolling stock will be afiorded a continuous tread when traveling either upon the main or siding rails.

t is another object of the invention to provide switch rails for the frog ata railwaysiding and to provide actuating mechanism therefor that is designed to be operated when the switch rails between the main rails and siding are thrown, whereby tofill It is a further object of the invention to provide switch rails for a frog that. will be. effectively supported and which will be opof the main switch points and which further are provided with means to retain the same in proper alinement with thepoint of the frog and to beefl'ectively held in such alinement to support the wheels of the rolling stock and consequently overcome the shock and ar incident to the passage ofthe ing'within the scope of the appended claims.

In the drawing:

Figure 1 is a plan view illustrating the application of the improvement,

Fig. 2 is a greatly enlarged plan View of the frog and a portion of the main and side rails arranged adjacent to the frog, illustrating the improvement, parts being broken away and parts being shown in section,

Fig. 3 is a side elevation of the improvement, and

Fig. 4 is a sectional View approximately on the line 44 of Fig. l.

In the drawing, the numerals 1 designate the rails for the main line and 2 the rails for the siding. The frog is indicated by the numeral 3, and the switch rails or :points by the'numerals 4c. The switchpoints are provided with the usufd bridle rod 5 having an extension 6 which 15 pivotally secured to one arm of a bell crank lever 7, suitable means (not shown) being employed for operating the bell crank lever to switch the switch points 4 to close either the main line orthe siding.

The second arm of the bellcrank lever 7 has pivotally connected thereto a longitudinally extendingrod S which in turn is coni'iected with one of the arms of a second bell crank lever that is disposed a suitable distance to one side of the frog 3. The second arm of the bell crank lever 9 has loosely connected therewith a rod 10 that is secured to a slide 11 to which the frog switch rails 12 and 13 respectively are loosely and pivotally secured, as at 1% and 15 respectively. The pivot members 11 and 15 pass through elongated openings in the slide 11 to prevent the binding of the parts and the free swinging of the frog switch rails when the bell crank levers are operated.

The frog switch rails or points 12 and 13 comprise each an. element shaped to correspond with the head portion of an ordinary railway rail, and the guard rails 16 and 17 to the opposite sides of the frog have theirhead portions cut away to receive the switch rails 12 and 13. Connecting the webs at the cut away portions of the said guard rails 16 and. 17 and if desired integrally formed with the said guard ralls 1s a platfor-11118 which is centrallychanneled "from its'upperface, and the side flanges 19 thus provided are beveled inwardly to receive the bent edges '20 upon the sides of the slide 11.

The webs of the rails upon which the frog switch rails or points 12 and 13 rest have lateral enlargements or bosses to more etfectively support the pivots 21 for the said frog switch rails. These enlargements or bosses 20 may be integrally formed with the main rails, but preferably and as illustrated in Fig. 3 of the drawings the bosses are formed upon central enlargements in the outer faces of the plates 22, the said plates being secured to the webs of the rails in any desired or preferred manner, as for instance,

--ject a suitable distance below the railsand thesaid projecting ends of the said pivots are threaded'to receive bolt members 24:, and the threaded ends of the pivots are provided with spaced transverse openings through which are adapted to be passed a and the webs of the rails upon which the said points rest to facilitate the ready turning ofthe points 12 and 13.

The switch points 12 and 13 have their outer ends beveled in opposite directions whereby to engage with the opposite sides of the frog when either of the said points are swung into contact engagement with the frog and also whereby to engage with the beveled ends of the rails 16 or 17 when the points 13 or 12 are swung to aline with the said rails. By this means it will be noted that the movement of the switch points is limited and also that the said points will be maintained in proper alinement with the opposite sides of the frog when the device is operated to open either the main line or the siding.

I In instances where the base of the fL'Og' 3 projects a suitable distance outward of the point of the frog, the said base could, with slight alterations, be made to support the platform 18.

From the above description, taken in con- TIQCtlOILWllZh the accompanying drawing, the

simplicity of the device, as well as the advantagesthereof will, it is thought, be perfectly apparent to those skilled in the art to 7 Copies 0!, this patent may be obtained forfive cents each, by addressing the Commissioner of Batents,

which such invention appertains without further detailed description.

headscutaway at the ends ofthe said rails,

the webs provided by the said cut away portions of the IilllSilitVlDg a laterally extending enlargement,'switch points, pivots for the switch points entering the said enlarge ments, a platform connecting the webs at the cut away portionsof the webs,a slide guided upon the platform, elements loosely connect ing the switch points with the slide, and operating mechanism for the slide.

3. A railway switch including a frog, the

rails in a line with the sides of the frog having their heads adjacent their ends cut away, and the heads of said rails to the oppositesides of the point of the frog being pivoted, the webs adjacent the opposite ends of the cut-away portions being widened, switch points received in the cut away portions of the rails and having pivots received in the referred to widened portions of the I to beveled heads of the rails in accordance with the direction. of throw of the said switch points, and meanscomprising mechanism connected with the slide for moving the same to actuate the switch points.

In testlmony whereof I aflix my signature.
