RAIL BEN-DER.

T 0 all 'whomvt may] concern:

VBeV it known that I, BA'srL E. DRafIMoND, a citizen of the United States, residing 'at Holden, in the countyjofLoganand State' of Test Virginia, 'have invented certain new and useful lnpro'vements in, Rail Benders; and I do hereby declare the following-to be, a ful'l, clear, andV exactl description vofthe;` inven'tion,-such as Will enable othersqskilled in the arttomvvhicli it'v appe'rtains`V to "make and use the'same.

This invention relates to new vand useful improvements in rail lbenders and has for its primary 4object the provision of means for moving the bendei` along the rail when the former vis'in adjusted posit-ion "or 1when placing 'the necessary pressure `on the rail to bring about the 'desired bend, thereby obviating the necessity 'of adjusting the bender each 'time it 'is'moved -from "one point to another on the rail. y

Another objectV 'of this invention is the provision of a rail bender of the above stated character which willV be simple, durable and efficient, and which may be manu'- factured and `sold at 'a `comparatively 'low cost. v

lilith these 'and-other, objects vin view as Will vbecome more apparent asth'e ldescription "proceeds, the invention lconsists in 'certain novel features of construction, combination, and arra-ngement'of parts as "Will be hereinafter more fully described and claimed. v

For a complete understanding of 'my invention, reference is to be had to the following description and-:accompanying drawings, in which Y Figure 1 is a top plan viewvillustrating a rail bender constructed in accordance with my invention, Y.

,i .Referring in Y*detail to' the"draivings, ftl'ie numeral 1 indicates a.` substantially 'trii angular shaped frame.; having secured TENT Ano-#Forte v thereto spaced axles 2'vvhich'are located adjacent each end of die"big'fhtA portion 3 of the frame and has our'naled thereon flanged Wheels 4 adaptedy to engage yonesideof 'the Y ball 5 offa Tail 6L The apex portion7 and the big-'ht portion 3 of the frame'l are connected by spaced guide lbars Sibetv'v'een Whichis slidab'ly mounted afhe'ad 9. `The' .sides ofthe head9 Vare provided With grooves' 10 to ,receive the guidebalr's to permit free sl-idfV Y ing movement-of lthe head towards and from theI rail 6.V The headistprovided vvfithfalre` movable flange 10s'o that said liead maybe removed from the guide vbars '8.` The outer ends of the'axles2 are suppolrtedby braces- 11 which are rivetedor"otherwise secured tothe bight portion `3 'ofthe `1frame- Gandare ofi'set vvas illustrated -at' 12-to permit f'ree rotation of the'flanged Wheels A feed screw 13 has Vswivel connection with the head 9V andV Yextends Ythrough an opening 14 formed in-the apex portioni" of the vframe 1, which lopening is provided with feed threads and the outer end of the feed screw ll''is provided with la'head 115, Which has openings ffthrough which a handle 17 may be vpassed. for rotating ythe feed screwv to move the head .()itowa'rds and from the rail 6. The-handle r1'7 has-fone endl pointed as illustrated yat 18l to facilitate the insertion ofthe samein anv fone 'ofthe The aXle 20 is supported by a brace 21.

The WheelV 21 is provided vWith spaced flanges 22 to define the groove and are adapted to engage the outer and inner faces of the ball 5 of the rail 6A. One face of the vvheel 21 has formed thereon counter sunk gear teethv 22 adapted to mesh With a pinon 23V journaled on a stub shaft 24 carried by bearings`25.

The bearings 25 are secured to thehead 9 upon opposite sides of a slot 26 Which permits the pinion 23 to extendV through the the latter are perferably ofthe flanged type. Y il head for engagement with the gear teeth 22 upon the wheel 21. A forked member 27 is j ournaled on the stub shaft 24 and straddles the pinion 23 and carries a spring actuated double end dog 28 adapted to rachet over the pinion 2B in one direction and adapted to bight or grip the teeth of said pinion when moved in an opposite direction so as to bring about rotation of the wheel 21 when desired. The dog 28 is capable of operation in a reverse direction. The forked member 2.7 is provided with a tubular portion 29 to receive one end of the handle 17 when it is desired to operate the ratchet mechanism 19.

in operation, the frame 1 is disposed over the rail G with the flanged wheels 1 in en-y gagement with one side of the rail and with the wheel 21 in engagement with the other side of said rail, and by turning the feed screw 13, the desired pressure or tension may of the wheel 21 which causes the frame to move along the rail without releasing the tension on the block 9.

From the foregoing description taken in connection with the accompanying drawings, it will be noted that a rail bender has been provided which may be easily and quickly applied to a rail and the desired pressure placed on the rail in a convenient manner to bring about the desired bending of the rail and also that the device may be moved along the rail from one point to another without releasing' the pressure or tension of the wheel 21 on the rail.

YWhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention what I claim is 1. A rail bender comprising a frame, wheels journaled to said frame and engaging one side of a rail, a head slidably mounted on said frame, a rail bending wheel j ournaled to said head and engaging the rail upon an opposite side from that engaged by the first named wheels, means for adjusting the head, gear teeth formed on the second named wheel, a pinion carried by said head and in mesh with the teeth of the second named wheel, and a ratchet mechanism for rotating said pinion.

2. A rail bender comprising a triangular shaped frame, lianged wheels journaled to said frame, spaced guide bars carried by said frame, a head slidably mounted on said guide bars, a grooved rail bending wheel ournaled to said head and engaging the rail, counter-l sunk teeth formed on one face of said rail bendingV wheel, a pinion carried by said head and in mesh with the teeth, a forked'member pivotally mounted on the head, a spring actuated dog carried byv said forked member and adapted to engage the pinion, a handle removably secured to the forked member, a feed screw carried by the frame and connected to the head, an apertured head carried by the feed screw and adapted to receive the handle for adjusting the lirstnamed head towards and from the rail.

3. A rail bender comprising a frame adapted to engage one side of a rail, a head mounted on the frame and adjustable to wards and from the rail, a circular element carried by. the head and contacting with the rail and having circularly arranged teeth. and a pawl and ratchet mechanism carried by the head and engaging the teeth to rotate the circular element.

In testimony whereof I affix my signature in presence of two witnesses.
