RAIL-J'OmT-PLATE. PRESS.

Application filed July 30,

My invention relates to a press for punchparticularly presses used in the manufacture of rail joint plates of the type which are provided with flanges shaped to fit the base flanges of rails.

Heretofore presses have been used for finishing plates, that is, equipped for the purpose of punching the holes in the web portion of the plate to receive the rail fastenings, notching the flanges of the plate to receive the spikes, and straightening in order to secure a true and uniform plate. Certain rail joint plates of the type for use with joints commonly known as continuous rail joints are made with a V-shaped transversely disposed flange portion the base of which is adapted to extend beneath the rail. customary with the latter type of plates to roll a bar of considerable length having the base of the flange portion bent out of the plane of the base, to facilitate the rolling operation, and after shearing the plates to the desired length the base is bent to its true position in a press suitable for the purpose. It has been the general practice toprovide a separate press for each of the aforementioned finishing operations and such presses were usually arranged side by side so that the operators carry the plate or slide it on skids from one press to the other, as each operation was completed. This necessitated the construction ofa number of extremely large and heavy presses to afford the necessary rigidity and strength required to perform the separate operations of punching, notching and straightening. The plates used in present day railway practice are extremely heavy and it is quite an onerous task to handle the vclaims taken with plates manually in order to transfer them from press to press. It is therefore the object of my invention to provide a, machine which is a self-contained unit capable of performing all the operations usually required to finish a rail joint plate.

More specifically the object is to provide a machine for punching, notching and straightening rail joint plates and includes a mechanism for mechanically handling the plate step by step during its passagethrough the F Fig. 5 isa similar section to Fig. 3 somemachine.

A still further object of my invention is the I It is 1926. Serial No. 125,846.

tools to intermittently advance the plate step by step to its different positions before the tools and eject thefinished plate from the ma- 7 chine.

lln its general aspect, my invention comprises the combination with a bed plate carrymg a series of dies, of a reciprocating head carrying punches which cooperate with certain of said dies to aperture the web of the plate, a second reciprocating head carryin a former adapted to cooperate with an anvi carried by the bed plate for straightening the Web portion of the plate and for the further purpose of securely holding the plate during the subsequent operation, a third reciprocating head the line of action of which is at right lines to the line of action of the aforementioned heads and carrying tools which cooperate with dies carriedby the bed plate for notching theextendin'g edge of the flange portion of the plate, said third head also functioning to bend the base of flange of the con tinuous rail joint type of plate into correct position when plates ofthat type are bein operated upon, a carrier mechanism carrie by one of the first mentioned heads formechanically advancing the plate step by step into the line of action of the aforementioned tools and ejecting the finished plate from the machine, and powermeansfor operating the several heads and carrier mechanism in a predetermined timed relation.

The, novel features will be more fully understood from the following description and the accompanying drawings in which; i

Fig. 1 is a front elevation of a machine embodying one form of my invention;

* Fig. 2 is a cross sectional view taken on line IIII Fig. 1;

Fig. 3 is a cross sectional view taken on I what enlarged and illustrates the rail joint lugs 22 along the length of the shaft,

plate of the continuous type in various stages of finishing;

Fig. 6 is a cross sectional view taken on line VIVI Fig. 1;

Fig. 7 is a cross sectional view .of the stripping device attached to the straightening or clamping head; and, 1 I

Fig. 8 is a detail of the cams for actuating the vertical heads.

Referring to the drawings: 10 indicates a bed plate and 11 a vertical housing comprising column members 12 tied at their upper ends by the cross tie-13.

A crank shaft 14 is rotatably mounted on suitable bearings attached to the column members 12. Journaled on the crank pin of said shaft 14 are a pair of spaced pitman members 15 which are pivoted to the cross head 16, as at 17. The rotationof the crankshaft 14 causes the reciprocation of the cross head 16 which is constrained to move in straight lines by suitable guideways 18 formed in the opposed faces of the column members 12. Mounted at the end of the cross head 16 (see Fig. 5). are multiple punches 19 which cooperate with dies 20 carried by the bed 10 to aperture the web of the rail joint plate when the cross head 16 is reciprocatcd as hereinafter described.

A toggle shaft 21 is rotatably mounted in suitable bearings attached to the column members 12 and has formed thereon, at each end thereof; within the housing, a pair of laterally extending lugs 22 which project in a downward direction and has also formed thereon, at about the same positions as the j I a pair of lugs 23 which extend upwardly. Each pair of lugs 22 are apertured to receive a pin upon which is journaled a link member 24. Each of the link members 24 is pivoted to the crosshead 25 in spaced relation to each other, and said crossheadjs mounted to reciprocate in suitable bearings 26 formed in the housing 12. Each pair of lugs 23 is apertured to receive a pin which carries a roller 27.

A cam disc 28 is keyed to each journal portion of the crank shaft 14, (see Figs. 1, 6 and 8) and is positioned on said shaft so that the roller 27 engages its cam surface whereby the rotation of the crank shaft causes the rocking of the toggle shaft 21 in one direction. In order to rock' the toggle shaft in the opposite direction, I provide second cam disc 29 keyed to each journal portion of the crank shaft 14 and in juxtaposition withthe disc 28. The periphery of the disc 29 engages a roller 30 mounted on the arm 31 which is pivot-ed at one end to the cross tie 13. as at 32, and extends across the crankshaft 14. An adjustable link 33 is pivoted to the extending end of the arm 31 and hinged at its other end to the lugs 34 extending laterally from the lugs v are so related to each other and the cam surfaces thereof so shaped that, when the crank shaft 14 rot-ates the toggle shaft is caused to rock intermittently back and forward whereby the crosshead 25 is reciprocated in a predetermined time relation with respect to the reciprocation of the cross head 16.

Detachably secured to the lower face of the crosshead 25 is a former 36 which is shaped as a counterpart of the inside shape of the rail joint plate. Then said crosshead is in its lowermost position the former 36 coa'cts with an anvil 37 carried by the bed plate 10, and which is shaped as counterpart of the outside shape of said plate, to straighten the platelongitudinally and laterally and at the same time hold it firmly during the subsequent operation of bending and notching the flange portion of the plate as hereinafter described. A crank shaft 38 is journaled in suitable bearings mounted on the bed plate 10. A pair of spaced pitmen 39 is journaled on the crank portion of shaft 38 and is pivotally connected to a horizontally disposed crosshead 40 which is slidably mounted in suitable guideways 41 on the bed plate 10. A multiple punch 42 is detachably secured to the front of the crosshead 40 and cooperates with dies 43 carried on the bed plate 10 to notch the flange portions of the rail joint plate when the crosshead 40 is reciprocated. The reciprocation of the crosshead 40 is so timed with respect The rail joint plate is moved step by step successively to its respective position before the finishing tools by a, mechanism described as follows. A pair of cam discs 44 and 45 respectively is keyed to the central shaft portion of the crank shaft 38 which is coaxial with the journal portion of said shaft. The cam discs 44 and 45 are coaxial and are disposed at 90 angular relation with respect to each other and engage with rollers 46 and 47, respectively, rotatably mounted on the spaced arms 48 and 49, respectively, which extend laterally from the rock shaft 50.

It will be seen that arms 48 and 49 are disposed at right angles to each other and the arm 48 projects vertically so that the roller 46 engages the periphery of the disc 44 at a point which is in close proximity to the horizontal plane passing through the axis of rotation of the crank shaft 38, whereasthe arm 49 projects horizontally and the roller 47 engages the periphery of the disc 45at a receive a air of tubular bearing members 51.

Spline 40v The mem ers 51 extend laterally be ond the forward face of the crosshead- 25 an project through suitable elongated clearance slots 52'provided in the crosshead 16 so that the movement of the latter is independent of the movement;v of the crosshead 25. Each member 51 has slidably and rotatably mounted therein a slide rod 53 which extends beyond the ends of said members. Thefslide rods 53 are connected respectively to arms 54, which extend upwardly from the rock shaft by means of a reach rod 55' which is hinged to the slide rod 53 and swiveled to the arms 54, whereby the rotation of the crank shaft 38 causes the reciprocation of'the slide rods 53 without interfering with the free rotary movement of same.

Suspended fromeach of-the slide rods 53 is a-carrier member 55 positioned one at each Each carrier member 55 is provided with a pair of spaced finger plates 57 which are detachably fastened to the inside face thereof {the finger plates 57 of one of the carrier members being disposed opposite the finger plates 57 of the other carrier member.

The finger plates are sha ed to conform with the exterior shape of rai joint plate being handled and opposed pairs. of

finger plates are adapted to support the rail joint plate when the carrier members 55 are 1n their closed osition as hereinafter deto each pf theslide rods 53 is a sleeve ,58 which is rotatably secured to the crosshead 25 by suitable means, such asithe adjustable brackets 59.

Extending laterally from each sleeve 58 are a pair of arms 60 and 61, which is disposed in the same plane and at an obtuse angle with respect to each other, and: the bifurcated'outerends of said arms are .pro-, vided with rollers 62. A pair of cam plates 63 is fixed to a stationary part of the machine, such'as the columns 12, and is spaced apart with their. respective cam surfaces directlytoward each other. Referring to Fig. 4, during the reciprocation of crosshead 25,

the rollers 62*are adapted to engage the cam plates 63, so that when said crosshead moves to its lower position the arms60 are moved toward each ot er. therebyrotating the left hand sliding rod 53 in a clockwise direction and right hand sliding rod 53 in a counterclockwise direction and thereby swinging the carrier members 55 to their open position.

When crosshead 25 moves upwardly, from its 'position shown in Fig. 4, the arms 61 engage their respective cam plates and are moved toward each other thereby rotating the respective sliding rods 53 in the reverse direction to that. aforementioned and thereby v swinging the carrier members 55 to their closed position. I

The crank shafts 14 and 38 are rotated through suitable gearing by the motor 64;. The gearing comprises a gear keyed to the armature shaft of the motor 64 meshing with a gear 65 keyed to the shaft 66 which is journaled in suitable bearings mounted. on the bed plate 10. Also keyed to the shaft 66 is a gear 67 whichmeshes with a gear 68 loosely mounted on the shaft 69 which is journaled in bearing formed in the columns 12. A suit- The clutch mechanism may be of any well known type and construction and is not,

therefore, shown and describedin detail.

Keyedto the shaft 69 is a gear 7 2 in mesh with the gear 7 3 which is fixed to the extending end of.the crank shaft 14. The shaft 69 extends through the housing 11 and has a gear 74 keyed at its end which meshes with a gear 75 keyed to the end of the crank shaft 38. It will be seen that when the motor is running and the treadle is depressed, the crank shafts 14 and 38 will rotate in unison.

In operation assuming the machine to be in its starting position shown in Fig. 1 it will be noted that the crosshead 25 is in its lowermost position, crosshead 40 is in its advanced position, the carrier members 55 are at about the midway position in their horizontal direction of travel and the crosshead 16 is almost at its lowermost position. The clutch is operated by pressing down the treadle 71 and the shaft 69 is caused to rotate.

The gear 7 3' rotates in the direction of the arrow shown at F ig. 6 and the crosshead 16 moves to its lowermost position and then begins to lift. As the crosshead 16 begins to lift the periphery of the cam disc 28 recedes from theroller 27 and the cam disc 29 lifts the arm 31, thus rocking the toggle shaft 21 in the direction to cause the crosshead 25 to plate A is placed on the forwardly oppositely disposed pair of finger plates 57.- In the.

meanwhile the crosshead 40- begins to rccede and when the crosshcads 16 and 25 approach their uppermost respective positions the periphery of cam disc 45 recedesfrom theroller 47 and allows the cam disc 46 to rock the rock shaft 50 whereby the slide rod 53 is moved longitudinally while it is being raised carrier members 55 to drop and the rail oint vplatefls lowered in its correct posltion on the block supporting the dies in the line of action of the punches. 'Ihe crosshead 16 cont-inues its downward movement, though somewhat slower than the downward movement of the crosshead 25, and the punches 19 aperture the web of the rail-joint plate for the reception of the rail fastening bolts. lDuring the aforesaid punching operation of the crosshead 16, the crank shaft 38 rotates to cause the crosshead 40 to advance toward the die block and the cam discs 44 and 45 are so positioned that the periphery of the disc 44 recedes from the roller 46, whereas, the cam disc 45 engages the roller 47 and causes the rock shaft/50 to rock in a counter clockwise direction, see Fig. 6, thus, moving the slide rods 53 longitudinally carrying the carrier member therewith. It Will be seen that the cycle of operations comprises the following steps; firstthe downwardmovement of the crosshead 25 carrying the carrier members 55 downwardly, then the downward movement of the crosshead 16, performing its punching operation and the advancement of the crosshead 40 while the carrier members 55 arebeing moved forwardly longitudinally. In the forward position of the carrier memher the rearwardly positioned pair of finger plates 57 are disposed in their correct position beneath therail joint plate resting on the dies 20 and a new rail joint plate is placed upon'the forwardly disposed pair of finger plates 57. \Vhen the vertically reciprocable ero'ssheads 16 and 25 again arecausied to rise, as previously described, and the carrier memhers move to their rearmost position, the rail joint plate previously punched is superposed oventhe anvil 37 and the new rail joint plate is superposed correctly over the dies 20. During the continued operation of the machine the crosshead 16 punches the web of the new plate, the crosshead 25 operates to straighten the previously punched plate and firmly holds same While the crosshead 40 advances. The advancing crosshead 40 bends the inwardly projecting flange of the rail joint plate to its correct position and at the same time notches the edge of the flange for the reception of the spikes. lVhen the crosshead 25 is again raised and the crosshead 40 is retracted the finished plate falls'from the machine. If the finished rail joint plate sticks to the former 36 attached to the crosshead 25, the spring pressed plungers 76 (see Fig. 7), eject the plate from the machine. tached to the crosshead 25, (see Fig. 6) are provided to strip the rail joint plate OK the punches which are attached to the crosshead 16. During the initial upward movement of the crosshead 16, the crosshead 25 remains stationary and in this manner the strippers are effective to remove the plate ofi' the punches, but, are moved from path of the next plate to be punched when the crosshead 25 is raised.

It will be seen from the foregoing description that I have devised a novel machine of unitary construction for finishing rail joint plates and provide a mechanism which feeds the work to the tools in sequence to the working steps. I While I have shown my invention in but one form, it will be obvious to those skilled in the art that itis not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and I desire. therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in he appended claims.
