To all whom it may concern:

Be it known that I, EDWARD F. GoBnN, a citizen of the United btates, residing at Muskogee, in the county of Muskogee'and State of- Oklahoma, have inventednew and useful Improvements in Rail-Benders, of which the followingis a specification.

This invention relates to a rail bender particularly adapted for usein bending mine rails, and one object of the same is to provide a bending mechanism of the class specified of a readily portable character having means particularly applied thereto for effecting an anti-frictional movement to render the operation of the main bending element easy and at the same time positive. A further object of the invention is to provide a rail bender with means for bending a rail either to give a convex or a concave configuration thereto, and to so construct the several parts that they may be readily operated to cause the rail bending element to shift and change movement automatically through the medium of a hand oscillating means which is readily reversible to produce and apply the bending pressure on the rail either in an inward or an outward direction. A still further object of the invention is to provide a rail bender having a-shiftable railbending member automatically operated by a manually controlled oscillating mechanism to secure the bending are desired and without liability of injury to the rail.

In the drawings:

Figure 1 is a perspective view of a rail bender embodying the features of the invention, and shown as looking upwardly from the lower side thereof.

Fig. 2 is a top plan view of the improved rail bender shown applied and the hand bar detached therefrom. I

Fig. 3 is a section taken on theline 3. 3. Fig. 2 with the hand bar applied.

4 is a section taken on the line 4. 4. Fig. 2, one .of the rail holding arms being broken away.

Fig. 5 is a detail sectional elevation of the ratchet dog and a part of the ratchet. disk cooperating threwith and shown in upright position and at a different angle to that shown by Fig. 6.

Fig. 6 is a horizontal section taken in the plane of the line 6. 6. Fig. 5. V Fig." 7 is perspective viewof the rail bender partially br'okenaway and showing a bending attachment applied thereto for straightening bends in rails.

The numeral 5 designates ayoke having a centrally enlarged body 6 substantially of circular form. as shown and from which arms 7 extend and are bent at right'angles and terminating in heads 8 with slots 9 having a contour simulating the head and part of a Web of a rail. Extending from the yoke 5 at points where the arms 7 emanate from thebody 6 are supports 10 for a flat cap or head disk 11, the supports 10 being bored longitudinally as at 12, see the dotted lines in Fig. 2, and throughthe portions of the arms 7 adjacentto the body 6 and the said supports 10 and reduced ends 13 of the cap or disk 11 bolts 14 are inserted and have their ends engaged by nuts 15 bearing on the reduced ends 13 of the cap or disk. The bolts 14 have their heads countersunk in the arms 7 adjacent to the body 6' and these bolts may be readily removed by. de taching the nuts 15 to permit dissociation of the cap 'or disk 11 when desired for repair or other purposes. Between the cap or disk 11 and the body 6 a ratchet wheel or disk 16 is mounted and has the opposite sides formed with grooves 17 which. are respectively adjacent to the inner opposing sides of the said body 6 and capo'rdisk 11. The grooves 17 form ball races'for a series of anti-friction balls 18 which bear against the inner opposing sides of the body 6 and the cap or disk 11. The ratchet wheel 16 is formedwith, peripheral grooves 19 atopposite sides of the teeth 20 thereof as clearly shown byvFig. 3, and therein-rings 21 are loosely seated and free to move. The rings 21 are respectively formed with-projections 22 and 23,- the projection 22 having'side flanges 24 to form a boxing, and with the remaining projection 23 the'said projection 22 provides a socket for a removablelhand bar or lever 25.- The two projections 22 and 23 have a bracket arm 26 interposed there between and secured by small bolts 27 to the projections adjacent to the ringsl'thei arm 26 being curved and terminating in an outwardly projecting angular tubular member or cylinder 28 which stands in diametrical relation to the ratchet wheel. 16. The bracket arm 26 with its tubular member or cylinder 28 moves uniformly with the rings. 21, these parts having an oscillating move-- ment imparted thereto by the similar move- I terminaljof the dog orpawl29randthe outer are adapted to be seated in opposite slots 37 bender or bending mechanism in fixed pos ment of the hand bar 25. Within the tubular member or cylinder 28 a dog or pawl 29 is mounted and has a reduced end 30 normally projected inwardly beyond the inner end of the said member or cylinder 28 to engage the spaces between the teeth of the ratchet wheel 16 to cause the latter to rotate in enedirectio n of movementza'nd in accordance with the adjustment of the said dog or pawl 29. The dogor pawl 29 has a reduced shank or stem 31 extending through a movable locking cap 32 fitted in the outer. end of the tubular member' or oylinder 2 8. The formation of the stem or shank 31 provides a shoulder 33 at the-outer end; o f the cylinder "has aninner annular shoulder 3 L Between the shoulder of the dog orpawl 29 and the annular shoulder 34 of the memberlor cylinderr 28, a spring ismounted and surrounds the" stem or shank 31, said spring operating to project the' dog or pawl inwardlyin normal operating position. The cap 32 'hasidiametrica lly opposedloeking lugs orfproj ections 36 which formedin the outer end oftlietuhular member'or cylinder 28. dog or pawl 29 is rotatable with the said cap to disengage the catch lugs 3 6lfrom the slots 37 ,andthe said dog or pawl ni ay bereversed soa s to cause a reversal ofioperation of the ratchet wheel or disk 16; i

Thea'rm's 7 with their slotted heads 8 constitute means forapplying and holding the tioii "relatively to ,the rail operated upon, and a bending element engages theratchet disk or wheel '16. This bending element consists of a screw stem 38 having a head 39 a slot 40 of the same form and open ing outwardly through the head in a manner similar to the slots 9 of the heads 8 of;

' the arms? The screw stem engages openingsff41,42, and 43, respectively formed in the cap or disk 11, the center of the ratchet for wheel 16 and the body 6ofthe yoke 5 as. clearly shown by Fig. 3. The openings 41am have smoothwalls, and the open ing threaded The bending element constructedas just explained is located cene tmhy between the arms 7 of the y ke .5 and movable inwardly and outwardlythrough the cap or disk 11-, ratchet disk or wheel 16 and body 6 in accordance with the feeding moyement'of the said ratchet disk or wheel 161an d which is regulated by the position of he qs or pawl 29. la ve y toth t e 20 o he'sa atch t disk- F 1 Tai p1'yin th lb de 0. bending [m nism,'therail be bent is suitably supporte ed on ts base flange and th heads 8 of the i '1 1er ePp ied er th ba l l f hsadan cwb' iapl ion of awn an a he s me t m helhe d 3,97 9f j e b ndi g l me i' 'e sd to similarly engage the rail between the points of engagement therewith of the heads ;8. Theldog or paw1' 29.is'ithen 'turned sozas to causea feedingopieration of the ratchet disk or wheel 16 relatively to the screw stem 38- to efi'ect an inward or an outward bend of the rail as may be desired. It will be understood that the socket for theha'ndbar 25 will be, uppermost and when the bender or bending'mechanism' has been applied as just explained, the operator inserts the hand. bar orlever 25inthe socketforming part of the rings 21 and then oscillates the said ratchet disk or wheel 16 to cause the screw the teeth 2O1to exert a pullingaction there- On' in either one of two directions inaccordance with the adjustment of the .said dog or pawl. The anti-frictional balls 18 renderthe operation of theratchet disk or wheel 16 very easy and materially lighten the power required to actuate ,the bending Y element engaging the said'ratchet wheel.

In Fig. 7 a bending attachment is shown applied ,and in operative relation to the henderand consists of a yokevcomprising. ,a lower horizontal member .4 1 and side arms 45 with slots .46 adjacent to the free ends thereofand through .it pull bar 47 :is remow ablymounted." Ii-1 thisqinstance the heads 8 of thearms 7 of the bender .are aterm inally formed with concave recesses or seatdepressions 48, one in each, to permit :said heads to be applied overland snugly engage the ball Of the rail. The bender jis not modified I in any other particular, and the operation thereof is precisely the same asin the :preceding disclosure. The object of this: attachment is to straightenrails that haveg surfacebends, as at 4:9, and in the useof the attachment in straightening rails ofathis type, the yoke ,iscaused to :engage'th e rail in the manner shown in .Y7V,and with. the lower horizontal member 14; under the base flange of the rail immediately.,bfeneatl1the surface bend, the ,arms 45 of the yoke extend upwa d y at opp site s des of he mi w h h P 11 b 47 place iiihe lats V Th P 1 bar 47 is also i erte through the slot 40 of thewhead 39logt1-the c ew teml the heads 8901f th zarm ffi the bender being rested on the lhall of the rail as shown. .;;B ,oj 'erating the screw stem 3 to tee th scr w;upWa lybym ans-9i;

the ratchet mechanism hereinbefore described the rail with the surface bend will be gradually straightened and repair of the rail will thus ensue without cutting out the surface bend portion as is the usual custom. By the means of the attachment, waste of material is avoided and a rail with a surface bend may be quickly repaired or restored to normal working position.

The improved bender or bending mechanism is light in structure and readily portable; may be quickly applied to and released from a rail; is strong and durable, and comparatively inexpensive in its construction.

ratchet disk between the said body and cover disk provided with grooves in the opposing faces loosely engaged by rings having flanges forming a socket to receive means for operating the rings on the ratchet disk and also provided with projections, a bracket arm interposed between and secured to the projections of the rings and carrying a cylinder extending at an angle therefrom and radially to the ratchet disk, the said cylinder having a spring-controlled pawl reversibly inclosed therein, and means movably engaging the outer free end of the cylinder and connected to the outer end of the stem of the pawl for reversing the latter in the cylinder and looking it in its adjusted position.

2. A rail bender of the type having an intermediate body with an opening therethrough, a cover disk secured to and spaced from the body, a ratchet disk mounted and freely movable between the cover disk and body, the body having rail-engaging arms and the ratchet disk provided with rings loosely'mounted thereon and also embodying a bending element having a screw stem movable through the centers of the cover disk, the ratchet disk, and the opening of the said body, combined with a cylinder connected to portions of the rings and disposed radially with respect to the center of the ratchet disk, the said cylinder having a spring-actuated pawl reversibly mounted therein, the cylinder having an outer rotatable locking cap to which the stem ofthe pawl is secured, the pawl being movable outwardly through the outer end of the cylin der and having a spring thereon between the cylinder and the pawl.

3. A rail bender of the, type having arm s with heads formed to engage the ball of the rail and an intermediate screw stem and head provided with ratchet and pawl operating mechanism therefor, combined with a bending attachment for removable engagement with the head of the intermediate screw stem, said bending attachment beingadapted to straighten a surface bend of a rail and consisting of a U-shaped yoke hav- 7 ing a rigid base and parallel rigid arms at right angles thereto, the base and arms always remaining in the same fixed relation and the arms adjacent to their free ends being provided with slots therethrough, and a pull bar loosely mounted in the slots of the arms of the yoke and removably engaged by the head of the intermediate screw stem between the ends of the arms of the yoke.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 8O nesses.
