PHILIP CAMELI, OF WILMINGTON, DELAWARE.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Application filed October 19, 1920. Serial No. 417,881.

To all whom it may concern:

Be it known that I, PHILIP OAMELI, a citizen of the United States of America, residing at Wilmington, in the county of New Castle and State of Delaware, have invent ed certain new and useful Improvements in Adjustable-Switch-Point Rail-Sectioi'ls, of which the following is a specification.

This invention relates to certain. new and useful improvements in adjustable switch point rail sections wherein the free ends of the switch points are caused to lie in intimate engagement with the supporting ties so that the wheels of rolling stock in passing thereover will not cause a vibratorymovement thereof.

The present invention further relates to improvements over the construction of adjustable switch point rail section shown and described in my patent granted June 22nd, 1920, No. 1,34%,259. The construction of adjustable switch point rail section as disclosed in my prior patent has particular reference to tie bar No. 1 to which the free ends of the switch points are connected. An offset extension. is carried by each end of the tie bar No. 1 and underlies the base of the adjacent rail while a vertically adjustable plate is mounted on the tie bar extensions and is adjust ble by screw bolts thread ed through the tie bar extcnsionsto cause the plate to engage the base of the rail with a consequent lowering movement of the tie bar and switch point carried thereby.

The improvement over this construction disclosed in this application embodies a mounting; of noirrotatable internally threaded thimbles or liearings within openings provided. in the tie bar extension and througli which thimbles the adjusting screw bolts are threaded for engagement at their upper oruls with the adjustable plate so that should the thimbles or bolts become worn or otherwise damaged, it will be only necessary to replace the thinibles and bolts while the original tie bar No. 1 may be employed indefinitely.

With the above and other objects in view, the invention consists in the novel form. combination and arrangement of parts here inafter more fully described. in connection with the accompanying drawings, and in which like reference characters indicate similar parts throughout the several views.

In the drawings,

tal. "ri'uu more in detail to the accompanying d twinge, there is illustrated a supportin it, 1 of usual construction upon which mounted the traclt rails 2 having: associated therewith the switch points 3 pi'witally mounted in the usual manner and connected adjacent their free ends by tie bars 41- and an end tic bar No. 1 bearing the reference numeral The intermediate portion of tie bar 1T0. 1, as shown in Fig.1. 1 carries a lateral bracket 6 to which a switch arm 7 is attached for throwing, the switch points in an obvious manner.

Detailed ((111f llTlifllllllll of tie bar No. 1 bearing: the ind icatinp; reference numeral 5 is shown in Figs. 2 to 7, the same being of elongated constrilotion having; a downard offset extension 8 at each end thereof that underlies the base flanges of an adjacent rail 2 while the switch points 3 are connected to the tie in adjacent each end thereof, and the offset extension by angle braces 9 secured to the tie bar and. the switch point by bolts 10. The switch point 3 rests upon the tie 1 while the ofiset extension 8 is spaced below the base flanges of the rail 2. A rail antra f plate 11 shown more clearly in Fig. 2 is positioned between the rail 2 and the offset extension 8 and carries depending pins 12 slidably extending through openings 13 in the extension 8 of the tie bar, the pins guiding the plate 11 in its vertically adjusting movements.

To provide for an adjustment of the plate 11 to cause the same to engage the rail 2 for lowering the tie bar No. 1 relative to the supporting tie 1, adjusting screws are associated with the tie bar extensions and plate and embody the provision of sockets 1 1 in the extension 8 within which are mounted tubular thimbles or bearings 15 carrying oppositely positioned laterally extending lugs 16 and a peripheral edge flange 16' that are countersunk in the upper surface of the tie bar extension as shown in Figs. 41 and 5 to prevent rotary movement of the thimbles relative to the tie bar extension. The thimbles 1 1 are internally threaded as at 17 and into which the screw bolts 18 are threaded, the upper ends of the bolts extending above the thimbles as shown in Fig. 2 for engagement with the bottom wall of the plate 11 while lock nuts 19 threaded on the bolt engage the bottom wall of the extension 8 to hold the bolts in their adjusted positions.

To provide for a substantially frictional engagement between the switch points 3 and the supporting ties to eliminate all vibratory movement thereof during the passage of rolling stock thereover, the adjusting screws 18 are operated to engage the plate 11 to movethe same upwardly into engagement with the base flanges of the rail 2 with a consequent lowering movement of the entire tie bar No. 1 and switch points 3 carried thereby. The practicability of this device will at once be understood when it is realized that should the adjusting screw bolts 18 become worn or damaged or should the threads of the screw and thimble become crossed, it will only be necessary to provide new thimbls and screw bolts while the tie, bar No. 1 may be employed indefinitely. The lateral lugs 16 carried by the thimble prevent rotary movement thereof relative to the tie bar. The thimbles 15 are frictionally re tained within the openings 14 provided in the tie bar extensions 8 and are so held against vertical movement therein while the lug 16 countersunk in the upper wall of the tie bar extensions prevents rotary movement of the thimbles.

While there is herein shown and described what is believed to be the preferable embodiment of the'invention, it is nevertheless to be understood that minor changes may be made in the form, combination and arrangement of parts wlthout departing from the spirit and scope of the invention as hereinafter claimed.

What is claimed as new is: 1. In comblnation, a pair of switch point rail sect ons, a tie bar connecting the same,
