Abstract
Abstract A vertical cylindrical member is supported by a frame adjacent a plurality of rotatable horizontally mounted rollers that support a plate to be marked. A carriage is mounted for vertical reciprocal movement on the cylindrical member. A piston cylinder assembly having an extensible piston rod positioned therein is secured at one end to the upper portion of the cylindrical member. The end of the piston rod is connected to the carriage. A shaft is rotatably supported by and positioned below the carriage. A marking wheel having a plurality of marking elements retained on the surface thereof is secured to the end of the shaft in overlying relation with the surface of the plate to be marked. The piston cylinder assembly maintains a preselected marking pressure on the marking wheel of the plate to be marked. A prime mover is mounted on the carriage and is drivingly connected by a single revolution clutch to the shaft to rotate the marking wheel and urge the marking elements into marking engagement with the surface of the plate to mark the plate. After each actuation of the clutch the marking wheel is returned to position the marking elements relative to the surface of the plate so that the plate may pass unobstructed beneath the marking wheel. Actuation of the clutch effects single rotation of the marking wheel and marking engagement of each of the marking elements with the surface of the plate to impress a preselected marking arrangement on the surface of the plate. A second piston cylinder assembly is connected to the carriage and the frame and is operable to laterally pivot the carriage through an angle of 90° to move the marking wheel into and out of marking position relative to the plate to facilitate a change of marking elements on the marking wheel or marking wheels on the shaft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
237 words
Apparatus for impressing a preselected mark on the surface of an object to be marked comprising, a frame, a support member secured to said frame, a carriage mounted for vertical and lateral movement on said support member, marking means to impress a preselected mark upon a surface of the object to be marked, said marking means including marking elements, said marking means rotatably supported on said carriage, drive means mounted on said carriage and drivingly connected to said marking means for rotating said marking means through a single revolution to urge said marking elements into marking engagement with the surface of the object to impress preselected marks thereon, a first piston cylinder assembly having a cylinder with an end portion pivotally secured to said support member, said first piston cylinder assembly having an extensible piston rod with an end portion pivotally connected to said carriage so that extension of said piston rod exerts a preselected marking force on said marking means to position and maintain said marking means in marking relation with the object to be marked, a second piston cylinder assembly having a cylinder with an end portion pivotally connected to said frame, and said second piston cylinder assembly having an extensible piston rod with an end portion pivotally connected to said carriage so that actuation of said piston cylinder assembly extends and retracts said piston rod to laterally swing said carriage in a horizontal plane.
Claim 2
Dependent Claim
237 words
Apparatus for impressing a preselected mark on the surface of an object to be marked comprising, a frame, a support member secured to said frame, a carriage mounted for vertical and lateral movement on said support member, marking means to impress a preselected mark upon a surface of the object to be marked, said marking means including marking elements, said marking means rotatably supported on said carriage, drive means mounted on said carriage and drivingly connected to said marking means for rotating said marking means through a single revolution to urge said marking elements into marking engagement with the surface of the object to impress preselected marks thereon, a first piston cylinder assembly having a cylinder with an end portion pivotally secured to said support member, said first piston cylinder assembly having an extensible piston rod with an end portion pivotally connected to said carriage so that extension of said piston rod exerts a preselected marking force on said marking means to position and maintain said marking means in marking relation with the object to be marked, a second piston cylinder assembly having a cylinder with an end portion pivotally connected to said frame, and said second piston cylinder assembly having an extensible piston rod with an end portion pivotally connected to said carriage so that actuation of said piston cylinder assembly extends and retracts said piston rod to laterally swing said carriage in a horizontal plane.
Claim 3
Dependent Claim
87 words
Apparatus for impressing a preselected mark on the surface of an object to be marked as set forth in claim 1 which includes, said support member including a vertical cylindrical member having upper and lower end portions rigidly secured to said frame, said carriage being pivotally mounted on said cylindrical member for vertical movement relative to the surface of the object to be marked, and said cylinder of said first piston cylinder assembly being pivotally secured at one end portion to said cylindrical member above said carriage.
Claim 4
Dependent Claim
84 words
Apparatus for impressing a preselected mark on the surface of an object to be marked as set forth in claim 1 which includes, a roll table positioned beneath said marking means, and said marking means positioned laterally of said support member beneath said carriage and movable with said carriage to position said marking means in marking position spaced above said table and above the surface of the object to be marked so that the object may advance on said table beneath said marking means.
Claim 5
Dependent Claim
54 words
Apparatus for impressing a preselected mark on the surface of an object to be marked as set forth in claim 1 in which said drive means includes, a driven shaft secured to said marking means, and clutch means for transmitting rotation to said driven shaft to rotate said marking means through a single revolution.
Claim 6
Dependent Claim
64 words
Apparatus for impressing a preselected mark on the surface of an object to be marked as set forth in claim 1 wherein, said second piston cylinder assembly connecting said carriage to said frame is operable upon actuation to swing said marking means laterally about said support member through an angle of about 90° to facilitate change of said marking elements on said marking means.
