FROGLESS RAILWAY-SWITCH- Specification of Letters Patent. Application filed May 3,1906. Serial No. 315,099.

connected end of which is beveled to a point at its juncture with the movable section 4. The opposite end of the spur-rail 5 is cut obliquely or beveled to engage the beveled end of the inner side-track rail when the movable sections of the tracks are shifted to bring the spur-rail 5 in line with the inner side-track rail upon the closing of the switch on the side track.

The movable section of the inner maintrack rail and the spur-rail 5 are bolted through their flanges to a connecting-plate 6, and between said rails is arranged a wedgeshaped block 7, which serves as abrace for the inner sides of said movable section 4 and the s ur-rail 5. The wedge-block p ace by bolts 8, which arepassed through the same and the sections 4 and 5 of the rail. The plate 6, secured to the lower side of the movable sections of the rail, is adapted slidably engage wear-plates 9, secured to the ties below said movable-rail sections, as shown. On the ties which pass beneath the movable sections of the rails are arrange stop-blocks 10, against which the outer sides of said movable-rail sections abut when the latter are shifted,said blocks also serving as braces for the outer sides of the rail-sections.

Pivotally connected to the joined ends of the rail-sections 4 and 5 is a laterally-projetin throw rod or bar 12, the opposite end of which is connected to a crank 13 formed on the end of an operating-rod 14, which is mounted on the ends of the ties and extends along parallel with the outer side rails of the main track to the ends of the switch-points 3, where said rod is connected to the throwrod 15 for the switch-points 3, end of said throw-rod 15 being connected to the usual switch-stand 16, arranged on the opposite side of the track. On the throw bar or rod 15 is adjustably No. 841,778. Patented Jan. 22,1907.

To all whom it may concern:

Be it known that I, THOMAS W. HARBER, a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvementsin Frogless Railway-Switches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in 'fro gless railway-switches.

he object of the invention is to provide a railway-switch of this character the crossingrails of which are constructed andarrange in such a manner as to dispense with the usual'frog.

A further object is to provide means whereby the movable portions of the rails at their crossing are actuated simultaneously with the throwing of the switch-point.

' A further object is to provide adjustable sto devices on the throw-rod of the movable rails whereby the latterare locked to form a free passage on the main-line track.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a section of railway-tracks arranged in accordance with the invention, showing the position of the parts when the switch is closed on the main line. Fig. 2 is a showing the position of the parts when the switch is closed on the side track. Fig. 3 is an enlarged detail plan view of the tracks at the crossing of the rail, showing the construction of the movable portions of said rails. ig. 4 is a vertical cross-sectional view on the line 4 4 of Fig. 1, and Fig. 5 is a similar view on the line 5 5 of Fig. 1.

Referring more particularly to the drawings, 1 denotes the mainine track, and 2 denotes the side track.

3 denotes the switch-points, arranged on the inner rails of the main and side tracks, as shown.

At the crossing of the inner rails of the main and side track the inner main-track rail is provided with a movable section 4, which is pivoted at one end, as shown. To themovable section 4 of the inner maintrack rail is secured a short spur-rail 5, the

mounted inner and outer stoplocks 17 and 18, adapted to engage the opposite sides of the outer maintrack rail when the switch-points and the movable sections 4 and 5 of the rails are thrown to clear the main track, thereby holding said movable sections of the rail in locked position. The stop-blocks 17 and 18 are preferably provided on their under sides with transverse serrations 19 adapted to engage similar serrations 20 on the bar 12. By means of the serrations 19 and 20 the blocks 17 and 18 may be adjusted in proper position to engage the opposite sides of the outer main-track rail. The blocks when so adthe opposite 7 is held in V place by means of bolts able section arranged in the inner rail of the main track, a spur-rail connected to said By providing the main and side track rails h movable i ing mechanism said sections are moved sisaid movable section and spur-ran, a throw mu taneously with the t owin of the rod or bar plvotally connected to the latter, switch-points. adjustablestop blocks arranged on the outer From the foregoing description, taken in ends of said throw-bars, an operating-rod, a connection with the accompanying drawin s crank formed on the outer end thereof to ent e constructlon and operation of the invengage said throwbar, and means whereb said operating-rod is actuated by the throw of the switchpoints, substantially as described.
