lMounted forV oscillation upon the mounting p1ece. f may be provided for each workpiece and the proper bar may be quickly inserted in the guide. The bar slipper carries a bullet catch 96 having ja head 91 for engagement with either of the yrecesses 95.
This guide angle which extends substantially parallel with the rivet pattern of the cap-strip of the spar 1|, thus providing a fixed member force-operation with the roller 65 of the rocker `14 being secured to the other side thereof. The
switches are arranged preferably equidistantly on each side of the trunnion bearings 52 of the rocker arm, and the rocker arm is provided with adjusting screws and 16, for engagement with thevswitches 13 and 14, respectively. These screws are preferably mounted upon a screw plate 80 carried by the rocker arm.
The templet device 38 of my invention is secured to the ram 8| of the riveting machine, and compris-es a stationary guide 82 having an attaching flange 83 for securement to a plate 84 carried by the ram. Slidably carried by this guide is a bar slipper 85. The slipper is held in place by means of slipper plates 86 secured to the back face of the slipper and each engaging a recess 90 formed in theback face of 4the stationary guide. The stationaryguide is provided with a longitudinal groove 9| in which is mounted a gauge bar 92. This gauge bar is :limited in its inward movement along the groove jpasses through the stationary guide and the gauge bar. The gauge bar is formed with a plurality of recesses 95 arranged at predetermined points and in accordance with the various laterally arranged operating stations on the work- By this arrangement a separate gauge bar This catch is mounted within a sleeve |00 carried by the slipper and has an index knob |0| secured to its outer end whereby it V,may be moved axially. A spring |02 is mounted ,within a recess workpiece having differently located lateral stations is to be operated upon, the gauge bar 92 may be removed by withdrawing the retaining pin 94, and replaced by a bar having apertures arranged in accordance with the workpiece.
As shown in Fig. 4, the upper flange |04 of the cap-strip 10 overhangs the inner rivet |05, so that the bucking tool |08 cannot be moved downwardly in a vertical plane but must be moved inwardly as it approaches the rivets. The final inward position of the tool when engaged with the heads of the rivets is shown in dot and dash lines. The bucking tool |08, as shown, is relieved on the side facing the flange |04 of the cap-strip 10 whereby itwill clear this flange when the tool engages the rivets |05. In order to accomplish the lateral movement of the bucking tool as the ram 8| is moved downwardly I employ a templet bar |05 which is carried by the slipper 85, This bar is mounted in a recess |01 formed in the slipper and extends upwardly therefrom, It is adjustable and clamped in position by means of a clamp screw ||0. The right hand edge of the templet bar is provided with operating surfaces ||3 and ||4 which engage with a templet roller carried by the mounting bracket. These surfaces are held firmly against the roller by means of the spring 46, and a spring clip H2 is carried by the templet roller stud in resilient engagement with the left hand edge of the templet bar, whereby it is kept in proper alignment. The operating surface ||3 of the templet bar is located in the plane spaced from the plane in which the surface I4 is located and joined thereto preferably by an inclined surface |5 so that as the templet bar is moved downwardly in relation to the roller l the roller will ride across the inclined surface I5 from the surface I4 tothe surface H3. During such movement the mounting bracket 42 will be moved to the left in the mounting plate 40 under the tension of the spring 46 and as it is so moved the rocker arm 6| will be oscillated slightly in counter-clockwise direction upon its trunnions 52 due to the engagement of the roller with the guide angle 66, thereby causing the switch 13 to be closed. This switch is so connected in the control circuit as to cause the cylinder and ram to be moved to the right until the bucking tool has been moved to the position where it will occupy the dot and dash line position shown in Fig. 4, at which time the rocker arm with its rod will be in neutral position. Such movement may be continuous or increment by increment each movement serving to bring the rocker arm again to its neutral position whereby the lateral movement of the cylinder and ram will be stopped. Ii, when the rocker arm has reached its neutral position, the templet roller has not yet reached the surface ||3, further downward movement cf the ram will cause further movement of the mounting bracket and consequent repeated operation of the switch 13. Consequently, as the bucking tool is being moved downwardly it is also being moved inwardly until it comes to its final position shown in the clot and dash lines.
Obviously, when the bucking tool is elevated to disengage the workpiece, the templet bar will travel along the roller and cause it to move up the incline |5 from the surface I3 to the surface |4; and, as it does so, the mounting bracket will be moved relatively to the mounting plate and thereby cause clockwise rotation of the rocker arm on its trunnions. This will operate the switch 14 to cause the mounting bracket 42 and .5 its as'sociatedparts to be moved to the left as viewed in Fig.' 4, thereby moving the anvil |08 laterally so that, as :it is elevated, it will clear the flange |04. i
Referring now to Fig. 10 where I show my device connected in a suitablev electric circuit, the feed motor'25, which is of the reversing type, is diagrammatically represented. Since the bucking unit must'beoperated in opposite directions, two contactors |20 and |2| are'provided for actuating, the motor. The contactor |20 Vis provided with Aan `operating coil |22, and the con- -tactor |2| is provided with an operating coil |23. Three normally open contacts |24, |25 and |26 areprovidedion` the contactor |20, and three normally 'open contacts 30, |3| and |32 are provided on the contactor |2|. The .power lines are represented at |33, |34 and |35. The contacts |24v and |30 are connected -to the power line |33; the contacts |25 and |3| are connected to the power line |34; and contacts |26 and |32 are connected to the power line |35. The contacts |24, |25 and |26 are connected by suitable leads to the motor 25 for operation thereof in one direction,vand-th e contacts |30, I3| and |32 are connected to the motor for operation thereof in reverse direction. The operating coils |22 and |23 of the contactors |20 and |2|, respectively each receivejcurrent from the power line |35. The switches |3Jand 14 are represented in the diagram andeach has one of itsv terminals connected to a common point |43 which, in turn, is connected to the power line |33. The other terminals |44 and |45 of these switches are connected respectively to the opposite sideof the operating coils |22 and |23. When the rocker .arm 5| is oscillated in counter-clockwise direction, the switch 13 will be closed as hereinbefore described, and when the rocker arm is moved in clockwise direction, the switch 14 will be closed,.thus actuating the contacter to which this actuating switch is connected. Obviously Wheneither contactor is actuated, the circuits thereof are closed` by lits contacts, and the motor 25 is operated to rotate the feed screws 33 in the correct direction to cause the desired lateral movement of the cylinder and ram.
