The bar or work piece is then advanced again and the preliminary forging is made into a final forging by cooperating dies of the desired formation, while the roller and the preliminary dies are effective on the succeeding portions of thev bar advanced to their respective positions. Thus the bar emerges at the rear of the machine completely forged into attached hinges with a comparatively small Hash or trimmed scrap loss.

The movable dies, which are the upper` dies in the form of the invention herein set forth, are operated from a plunger which is connected to an upper crank shaft. This crank shaft also operates the roller through a suitable cam connection which provides the required dwell, and through an eccentric connection which produces the longitudinal movement of the roller.

The crank shaft is also connected to a feeding frame provided with grippers which' are automatically engageable with and disengageable from the metal bar at the proper time in the sequence of operation.v At the front of the press and engageable with the unformed bar is one set of gripping devices, and at the rear of the press are additional gripping devices arranged for engagement with either the upper and lower sides of the formed hinges or else for engagement with' the sides of the hinges, for holding the series of hinges against longitudinal movement during the forming operations, but causing the advance of the series of hinges at the proper time after the forming dieshave been separated'.

The bar feeding mechanism operates 'step by step during the entire press operation, and in order to permit a heated bar to be inserted into the front feeding grippers and in proper relation with the forging dies without stopping the machine a lockout is provided adapted for operation at a predetermined time in the sequence of press operations but under the manual control of the operator, whereby the front grippers can be held apart to provide for the insertion of the heated bar, the construction also being such that a locating screw is raised into the proper position for locating the end of the work bar so that it will have the proper relation to the roller and forging dies at the time it is engaged by the grippers.

Referring now more particularly to the drawings by reference numerals, 10 represents the frame, ll-the stationary bed, and 12 the main crank shaft'of a press. Power is supplied to 'the crank shaft 12 through suitable gearing 13 from an electric motor 14, the crank shaft being connected through the connecting rod 15 to cause vertical reciprocatory movements of the upper die supporting member 16 which is suitably guided in the press frame.

The crank shaft 12 is connected by gears 18 to a horizontal shaft 19' on which are cams 20\and 21, see Figs. 2 and 3. The cam 20 is engaged by a roller 20 while roller 21' engages cam 21. The rollers 20 and 21 are rotatably carried on a frame 22 which is oscillatably or pivotally mounted on an axis 22. The frame 22 is also pivotally connected at 23 to a link 24. The construction 4just described is such that as the cams 29 and 2i are rotated counter-clockwise as shown in Fig. 3, at the same speed as the crank shaft, the frame 22 is rotatably oscillated under the positivecontrol of the two cams and the two rollers, producing a positive vertical reciprocatory movement of the link 24.

The lower end of the link 24 is pivotally connected as by a ball and socket joint 26 to the roller carrier 27 which is slidably guided for vertical movement on the front side of the press fratrie.. As shown in Figs. 3 and 4, the roller carrier 27 movably supports the slide 28 for horizontal motion therein, the slide and the roller car- Arier having cooperating guide or slide surfaces 30.

The slide 28 is symmetrical in form, as shown in t Fig. 4. In it is rotatably mounted the shaft 31 of the roller segment 32. Keyed to the shaft 31 is a rack segment 33 engageable with rack teeth 34 on the roller carrier. A slot 35 is preferably provided in the side of the roller carrier to nfacilitate lubrication of the parts. It will be understood that a segment gear and rack are provided at 'each side of the roller, causing vthe roller to move the shaft 19. The relationship of the parts shown in Fig. 3 is such that with the plunger down and ready to ascend, the roller is at the left-hand end of its stroke and in a depressed or dwelling position but ready to start moving upwardly.

By means of the roller operating mechanism as just described `it will be apparent that the roller may be forced down into the heated bar of metal which rests on the fixed base 40 ahead of the die position, dwelling in its down position for about 180 movement of the crank shaft during which movement the arm 38 is operated through its eccentric driving connection with the cam shaft to force the roller to the left as viewed in Fig. 3. The roller segment 32 is so timed, and its stroke is such, that the bar will be very materially reduced in thickness throughout a substantial porgagement between the preliminary forming dies and 46 which partially form the length of bar including theunrolled portion 42 into a shape ap.-A proxirnatingr the desired final shape. During the time the preliminary dies 45 and 46 are effective on the work, the roller 32 is completing the rolling of another flattened portion on the succeeding length of work. The bar is then fed forwardly again between the finishing dies 47 and 48 which produce the nal shape desired. The dies 45 and 47 are movable together and are both attached to the lower side of the press plunger. The lower dies 46 and 48 are held on the press bed. A knockout bar 50 is preferably provided in the upper die and arranged to be forced downwardly for ejecting the formed article from the upper die by means of a pin 51 provided in the per end of pin 56 which is reciprocated by anv arm 57 connected to link 58 'adapted to be'reciprocated at the proper time in the sequence of operations by roller and cam means designated generally 59, see Figs. 1 and2. 'Ihe upper end of the pin 56 is normally flush with the bottom .of the lower die 48.

As herein shown, the lower dies 46 and 48 are Y provided on a slide block 60, see Fig. 1, so that 48 are of identical ,form and construction but are cool.

adapted for successive cooperation with the upper dies in vorder that the lower dies may be kept The means for reciprocating the-die carrying block comprises a link 6l, bell-crank 62, slide 63, link 64, arm 65,-and rollers 66, 67 engageable respectively with cams 66' and 67' on a shaft 68, which is connected by gearing 69 to the cam shaft 19, the construction being such that for each revolution of the crank shaft one set of roller dies will remain xed in position and the dies will then be shifted to bring the other pair of lower dies into proper alignment with the upper dies while the plunger is in an upper position.

Referring now more particularly to Figs. 1 and 5, the feeding means by which the bar is advanced in a step by step manner comprises a feeding frame 70 embodying laterally spaced bars 71 and 71 guided for longitudinal movements in bearing brackets 72 on the press frame. At the front end of the bars 71, 71 are the front grippers 73, '74 which are arranged for engagement with the sides of the heated bar. The gripping device 73 is detachably set in a. desired position by means of the adjusting screw 75. The opposite gripping device 74 is adjustably secured on a plunger 76 which is guided in the carrier 77'for horizontal sliding movement. The outwardly extending end of the plunger 76 is provided with projections 78 between which is arranged an arm 79 nxed to an oppositely projecting arm 80 and pivotally supported on the axis 8l. The arm 80 is adapted to be operated by projections 82 on a spring pressed bar 83. The operating spring 84, for the bar 83 yieldingly urges the bar 83 toward the right as viewed in Fig. 6 thus tending to yieldingly hold the gripping device l'74 against the work. The bar 83 is rigid with a roller carrier 86 on which a roller 87 is rotatably mounted. This roller 87 opcrates on a flat plate 88 which is shown in its retracted position in Fig. 5, but which is adapted to be moved to the left at the proper time in each cycle of operations of the press in order-to release the gripping device 74 from the work. When the plate 88 is moved to the left the roller 87 and the bar 83 are forced to the left against the action of the spring 84, thus positively pulling the gripping'device 74 toward the right and releasing the work. Y It will be understood that the entire feeding ,frame and gripping device are moved constantly back and forth during pressk operations,-

the roller 87 operating on the plate 88 which is arranged parallel to the path of movement o f the feeding device so that feeding movements of the frame are without eilect on the grippers.

The plate 88 is slidably guided 0nthe press frame for horizontal reciprocatory movements. A link 90 is pivotally connected to the plate 88 and to a double armed lever 91 which is pivotally connected to a reciprocatory bar` 92. When this bar 92 moves horizontally in one direction (upwardly as viewed in Fig. 5) the plate 88 is moved to theA left. The bar 92 is moved in the direction of its length by means of cams 93 and 94 on the cam shaft 19 engaged by cam rollers 93 and 9'4 carried by arms both of which are fixedl to the rock arm 95 which is pivotallyconnected to a link 96 as shown in Figs. Iv and 2. The lower end of the link 96 pivotally connects toaI bell-crank lever 97, the lower end of which is provided with a bifurcated slide guide embracing the block 98 which is suitably held on the bar or rod 92. The cams 93 and 94 are so formed as to provide 'a positive movement of the bar 92 in both directions and at the proper time in the sequence of press operations so that the gripping device 74 is released from the work when the feeding frame moves forwardly but is engaged with the work during the rearward or feeding movement of the feeding frame in order to cause the work to move with the feeding frame 'throughout a complete feeding stroke. as shown in Fig. 11, is at a time when the roller 32 and the upper dies 45 and 47 are raised. It will be seen from the figure men-- tioned that the point in the cycle of press operations at which the feeding movement takes place is just before the plunger descends, the grippers being open during the time the roller is flattening out the work piece.

The advancing end of the formed work is also adapted to be held during feeding movements by suitable gripping devices so that the bar is pulled .100

as well as being pushed in a step by step manner. 'I'he rear gripping devices which are adapted for engagement with the formed hinges are shown in Fig. 7 and at the upper portion of Fig. 5. The

rear gripping devices are so arranged that the work may be held either at the sides or at the top and bottom as desired, as it will be readily understood that with an article such as a hinge having substantially` constant width and having a thickness whichvaries at different portions of the hinge it will be advantageous to grip the formed articles on the sides although other articles of a different form might better be grippedV at the top andbottom. The' two grippers 100 and 101 are therefore provided at the rear of the feeding frame, gripping device 100 being adjust'- ably secured in support while gripping device 101 is adjustably held in a reciprocating plunger 102, reciprocally mounted in support 111, in substantially the same manner as has previously been described with reference to the forward gripping devices. The plunger 102 is operated by a double armed lever 103, which is controlled by the bar l 104 influenced by a spring 105 which normally tends to urge the gripping device 101 away from the work in the same manner as has previously been described with reference to the forward grippers. The bar 104 is controlled by a roller 106 operating on a flat plate 107 which is controlled by the rod 92 so as to move simultaneously with and in the same direction as the plate 88 so that the rear grippers will be engaged with the work or disengaged from the work at the same time the front grippers are correspondingly moved; In the solid line position shown in Fig. 7, the grippers'100 and 101 are engageable with the sides of the work. However these grippers are vreadily removable from the 'supporting parts 110 either' a vertical or horizontal direction depend- 150 ent on its position in either the support 110 or support 110a. Both grippers 100 and 101 may be so adjusted with respect to its holding or operating means that it advances yfar enough toward the work for eiective gripping action.

The feeding frame including the side bars 71, 71' 4and the end frame members at the front and rear of the press which support the grippers is bodily movable in a reciprocatory manner, being pivotally connected to a link member 119, see Figs. 5 and 8, the rear portion of the link member 119 being pivoted to an arm 116 which is secured on the oscillatory shaft 117. An operating element 118 is fixed to the shaft 117 and to the arm 116 and is pivotally connected to the feed operating link 120 which extends upwardly to link 121, operated by cams 122 and 123 engaged by rollers 122' and 123 on arms rigid with n the link 121. The cams 122 andl 123 are provided `forward grippers may be locked out so that they cannot engage the work, in order that a new bar can be inserted between the front grippers without stopping the press. This lockout is under the manual control of the operator, the construc- 1 tion being shown more clearly in Figs. 2, 6, 8

and 9. At the proper time in the sequence of Voperations a pin 125 may be raised vertically upwardly so as to come into the path of movement of a lug 126 provided on the bar 83 of the gripper operating mechanism, at a time when the gripper '74 is released from the work. Then after the plates 88 and 107 are moved to retracted positions the bar 63 will be prevented from returning and the grippers will be held open. This pin 125 is provided on an arm 127 secured to the 'upper end of a bar 128. The lower end of the bar 128 is controlled by an arm 129 to which is secured a gear segment 130 and to which is also secured a lever pivoted to the upper end of a release link 131. The gear segment 130 is in engagement with a gear segment 132 xed with relation to arm 133, arm 133 engaging the lower end of a bar 134 which is fixed to a threaded rod 135 normally urged upwardly under the control of the spring 136. The spring tension may be adjusted by means of the nuts 137 on rod 135. This spring tends to move the plunger 134 upwardly and to move the control link 131 upwardly although normally the control link 131 is held in a lowered position by the foot bar 139 having a gravity actuating lock 140 which normally holds the foot bar 139 in'a depressed position as shown in Fig. 6. However, when the step 141 of the gravity lock is depressed, the depending arm 142 is movedaway from over the foot bar 139 permitting the 'latter to be moved up under the action of the spring 136. When the bar 139 is moved up under the action of the spring the pin 125 is projected so as to hold the front grippers open ready for the insertion of a bar. Such raising action of thebar 139,' however, can only take place after the lug 126 is moved out of the path of the pin 125, the foot bar 139 being held down until the lug 126 moves clear of the pin and opens the front grippers.

At the same time the pin 125 is raised to lock out the front grippers, a locating screw 146 (Fig. 8) is elevated. The head of the screwiforms see Fig. 8.

an abutment for the advancing end of the work thus locating the work in the properposition with respect to the feeding and gripping mechanism at the time the closing of the front grippers takes place. The locating screw 146 is adjustably threaded in a frame 147 carried for vertical sliding movement in a bracket 148 on the press frame. The frame 147 is secured to the upper end of plunger 134 so that as the plunger 134 moves up the locating screw will be moved up from a normally retracted position below the path of -the bar, see Fig. 8, into the path of movement of the front end of the work bar.

The locating screw 146 is moved toa retracted i position at the same time the lockout pin 125 is retracted, since these two devices are interconnected by the mechanism previously described including the rack segments 130 and 132. After a new bar is inserted between the front grippers with its advancing end against the locating screw, and the operator desires to have the front grippers close and the locating screw move down, he presses on the foot bar 139, thus moving the lockout pin 125 down so that the front grippers can be closed and also pulling down or retract ing the locating screw. Such movements, however, of the pin 125 and locating screw can only take place at the proper time inthe sequence of operations, because the oar '139 is held in its upper position after having moved to that position, by means of a holding lever 150 xed with respect to the arm 129 and gear segment 13'0, This lever 150 is provided with a curved seat 151 which is adapted to be engaged by the side of a plunger 152 after the lever 150 has been swung to the right from its normal position due to the upward movement of the foot bar 13'9. The pin 152, shown in Figs. 5 and 9,

is slidably guided so as to be projectedinto the return path of movement of lever 150, being operated by link connections 155, 156 and 157 to an arm 158 provided on a shaft 159 which is controlled by the 'bar 92, it being remembered that the bar 92 is moved endwise by cams operated from the crank shaft to cause the engagement and disengagement of the grippers. When the arm 158 is moved over to the right from the position shown in Fig. 9, the pin or plunger 152 tends to be projected into'the'path of movement of the lever 150, but if the lever 150 is in front of the plunger, a spring 160 provided on the link 157 is compressed so that the plunger l152 can be projected subsequent to the raising of the foot bar 139. When the foot bar-139 is in its depressed position and the gripping as well as the feeding devices are operatively associated with the press mechanismthe compression spring 160y is operated without causing the projection of the holding plunger 152'.

It will, therefore, be apparent that without stopping the operation of the plunger and with out stopping the reciprocatory feeding operations of the feeding frame, the -front grippers may be held open and the locating screw may be raised so that the bar can be inserted between the moving grippers, 'and at the proper time in the sequence of operations the operator is enabled topress the foot bar 139 down against the action of the spring 136 and move the lockout pin 125 so as to permit the normal functioning of the front grippers, thisaction also retracting the locating screw out of the advancing path of movement of the bar of work. Then when the grippers move the work forwardly the end of the work piece will be in a proper position with :,ovaaso respect tothe roller so that there will be no waste or scrap loss ofthe first article formed.

While the method herein described, and the form of apparatus for carrying this method into effect, constitute preferred embodiments of the invention, itis to'be understood that the invention is not limited to this precise method andv form of apparatus, and -that changes may be made in either without departing from the scope of the invention which is defined the appended claims.
