To all whom it may concem:
Be it known that I, GEORGE W. CURTIS, a citizen of' the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Rail Benders, of which'the following is aspecification.
This invention relates to improvements in bending tools and particularly to bending tools for rails and the like.
The primary object of the invention is to provide a simple, inexpensive bending too-l capable of exerting great pressures on a rail or the like for the purpose of bendingthe rail sharplyor gradually.
Another object of the invention is, to furnish a rail bender which is reversible, that is, one which may be turned upsidedown to grip either side of the headof the rail or which may be used at either side of the head of the rail in reversed positions.
A further object of the invention is to provide a rail bender having a beam provided at one end with an outwardly extending abutmentrecessed at opposite sides of itsextremity inorder toabut against either side of the head of a rail. a
A still further object of the invention is to furnish a rail bender with a gripping member designed to grip either side of the head of a rail and to be reversed to engage either 7 side ofthe head of a rail.
I Another object of the inventionis to-provide a bending head swivelled to an adjusting screw and provided with a diametrically arranged lug designed to abut against elther side of the head of a rail.
A further object is to furnish a rail bending tool having an L-shaped beam provided at one-end with an abutment to engage either side of the head of a rail and provided at its opposite end with a reversible bending head, and a reversible gripping member adjustably mounted on the beam between the ends of. the latter.-
With the foregoing objects outlined and Fig. 2 is a top plan view of the tool.
Fig. 3 is a vertical transverse sectionalvi'ew taken on line 33 of Fig.2. v
a Fig. 4 is a similar view taken on line 4-4 ofFig.2.
In the drawing, 1 designates astrong metal beam provided at one end with an angular extension or foot 2 terminating in an abutment head 8 having a horizontally disposed central flange 4' designed to rest with either of itsupper or lower surfaces on the upper surface 5 of, the rail to be bent.
The head3 is recessed as shown at 6 on opposite sides, of the flange ,4 in order to provide pockets on opposite sidesof the head to receive the head of the rail. It may fbeseen from Fig. lftha't one of the pockets 6 is engaging the head of the rail and'it will be apparent that the opposite pocket may engage the head of the "rail when the beam 1 .is turned upside down or reversed.
The opposite endof the beam 1 is provided with a threaded-aperture to receivethe screw ,7. This screw has apertures 8 at its outer end to receive a lining ban (not shown), employed to turn the screw. The
inner end of the screw is provided'with a spool-shaped head 9 on which'a bending head 10 is swiveled, the bending head being held in place by a screw 11 which extends into the groove of the head 9, Th'e'screw 11 that is, the bendingfhead is also reversed,
Slidably mounted on the beam 1 inter mediate the ends of thelatter', is a substantially T-shaped gripping member13 having an aperture14c'through which the beam 1 passes. The head of this gripping member has recesses 15 at opposite sidesyof its web 16, and as shown in Fig. 1, one of these recesses is engaging the head ofthe railwhile the other recess lies above said head. When the beam 1 is reversed, it is obvious that the uppermost recess 15 may be brought into en ga ement with the head of the rail.
' operation, the parts may be arranged as shown in Fig. 1, and thena linerbar may prevents the headllO from passing axially be inserted in one of the apertures 8 for will function as afalemmrand the rail will be bent about this point. As shown in Fig. 1, the device is arranged to bend the rail toward the left or in a counter-clockwise di rection. If it is desired to bend the same to= ward the right or in a clockwise direction the Parts. are turned upside down, so that the"uppermost-recesses..6 and 15 engage op posite sides of, the head of ihelrail, and then when the screw 7 is turned the rail will be bent toward the right. The flange 12 ot thebending heaid, willof' course lie on the uppe -sur fibef of the rail during the bendin .in'eit'herdirection.
mm the foregoingit is believed that the construction, operation and advantages of thfiinventionmay be readi-ly understood "b u it is believed desirable to point out that in usingthis ra'ilbender for switch-work, the opeiiatonmay stand in front of the switch, sort-hat he maybe occupying a safe place. The. device, can be used by construction gangs for breaking .orbending rails, and with this device as little as siX inches may be broken off the rail, while with other types of rail' breakers it is necessary to waste from fifteen to eighteen inches of the rail. The device is preferably of such lengththat adjustment m y be made from six to eighteen inches; so that a .iece' lying between these sizesmay be. broken from the rail if desired. The device may be used for switchwork where the switch rail leads either to the right or left. The operator can stock either side with thisrail bender and work in front of the switch with absolute safety.
It is obvious that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in, the claims;
What is claimed and desired to be securedby, Letters Patent is:
1. A rail bender including a beam provided at one end with an abutment head having upper and lower recesses, either one of which may receive the head of a rail, gripping member slida-bly mounted on said beam and. adapted to hookover the head of a rail, andabending, headprovided at the opposi e" endof said beam and provided with a screw -for'moving these-me away from said beam.- I
2. A rail bender includinga beam provided at one end with an abutment head adapted to engage either side of the head of a rail, a substantially T-shaped gripping member slidably mounted on said beam and having oppositely extending hooks designed to engage either side of the head of a raih and a screw threaded in the opposite end of the beam provided with a bending head adapted to engage either side of the head of a rail.
3,2; rail bender including an. L-shaped metal beam having recesses provided on opposite sides of the foot of the L designed to engage either side of the head of a rail, a gripping member slida'blymounted on said beam and shaped to engageeither side of the head of a rail, a screw threaded in the end of the beam opposite the end carrying the foot, and a bending head swiveledon said screw and provided witha fiangeadapted to engage either side of the head of the rail.
i. A rail bender including a metal beam provided at one end' with a threaded aper ture and at its oppositeend with an angular lug terminating in a head provided with an outwardly extending flange having recesses at its opposite sides to' engage either side of the head of a rail, a gripping member slidably' mounted on said beam and hav ing oppositely extending hooks designed to engage either side of the head of a rail, a screw engaging the threads of said aperture, and a bending head swiveled on one end of said screw and adapted to engage either side of the head of a rail.
A. rail bender including an Lshaped vmetal beam having a horizontally disposed outwardly extending flange arranged at the extremity of the foot of the L, upper and lower recesses in the foot arranged at op posite sides of said flange, each of said recesses being adapted to receive the head of a rail, a substantially T-shaped metal gripping member slidably mounted on said beam and having oppositely extending hooks, either one ot which is adapted to grip the head of a rail, a screw mounted in the end of the beam opposite the end having the foot, and a head swiveled on said screw and having a diametrically extending flange adapted to engage either side of the head of a rail.
In testimony whereof I afiiX my signature.
