Abstract

Abstract A marking press device for impressing identification marks upon iron slabs or plates manufactured upon an iron manufacture production line, comprising a truck or carriage capable of moving forwardly toward a plate to be marked, a marking press mechanism supported by the truck and capable of moving relative to the truck a predetermined distance by an auxiliary driving mechanism, reciprocable pistons fitted within cylinders of the marking press mechanism, and marking elements also fitted within the cylinders and actuated by the pistons. Reciprocal drive means retract the truck away from the plate at the conclusion of the marking operation, as well as move such forwardly again for the next operation, and the apparatus also includes means for automatically stopping the marking press mechanism at a predetermined position relative to the slab to be marked as well as means for automatically adjusting the position of the marking press mechanism whereby the marking element will be perpendicular to the surface of the slab upon which the marked indicia will be impressed.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 179 words
An automatic marking press device comprising: a truck movably disposed upon guide rails; marking press means supported by said truck for marking a plate; a driving mechanism connected to said truck for moving said truck forwardly and backwardly upon said guide rails whereby said truck and said marking press means are able to be moved relative to said plate to be marked; auxiliary driving means for moving said marking press means longitudinally, laterally, and rotatably within a horizontal plane relative to said truck whereby the relative position between said truck and said marking press means and between said marking press means and said plate to be marked may be adjusted; means for automatically stopping said driving mechanism of said truck; and retractable contact rod means projecting from said marking press means toward said plate to be marked and adapted to be retracted, upon contacting said plate to be marked as said marking press means is moved toward said plate to be marked by said driving mechanism, for actuating said means for automatically stopping said driving mechanism of said truck.
Claim 2
Dependent Claim 179 words
An automatic marking press device comprising: a truck movably disposed upon guide rails; marking press means supported by said truck for marking a plate; a driving mechanism connected to said truck for moving said truck forwardly and backwardly upon said guide rails whereby said truck and said marking press means are able to be moved relative to said plate to be marked; auxiliary driving means for moving said marking press means longitudinally, laterally, and rotatably within a horizontal plane relative to said truck whereby the relative position between said truck and said marking press means and between said marking press means and said plate to be marked may be adjusted; means for automatically stopping said driving mechanism of said truck; and retractable contact rod means projecting from said marking press means toward said plate to be marked and adapted to be retracted, upon contacting said plate to be marked as said marking press means is moved toward said plate to be marked by said driving mechanism, for actuating said means for automatically stopping said driving mechanism of said truck.
Claim 3
Dependent Claim 179 words
An automatic marking press device comprising: a truck movably disposed upon guide rails; marking press means supported by said truck for marking a plate; a driving mechanism connected to said truck for moving said truck forwardly and backwardly upon said guide rails whereby said truck and said marking press means are able to be moved relative to said plate to be marked; auxiliary driving means for moving said marking press means longitudinally, laterally, and rotatably within a horizontal plane relative to said truck whereby the relative position between said truck and said marking press means and between said marking press means and said plate to be marked may be adjusted; means for automatically stopping said driving mechanism of said truck; and retractable contact rod means projecting from said marking press means toward said plate to be marked and adapted to be retracted, upon contacting said plate to be marked as said marking press means is moved toward said plate to be marked by said driving mechanism, for actuating said means for automatically stopping said driving mechanism of said truck.
Claim 4
Dependent Claim 179 words
An automatic marking press device comprising: a truck movably disposed upon guide rails; marking press means supported by said truck for marking a plate; a driving mechanism connected to said truck for moving said truck forwardly and backwardly upon said guide rails whereby said truck and said marking press means are able to be moved relative to said plate to be marked; auxiliary driving means for moving said marking press means longitudinally, laterally, and rotatably within a horizontal plane relative to said truck whereby the relative position between said truck and said marking press means and between said marking press means and said plate to be marked may be adjusted; means for automatically stopping said driving mechanism of said truck; and retractable contact rod means projecting from said marking press means toward said plate to be marked and adapted to be retracted, upon contacting said plate to be marked as said marking press means is moved toward said plate to be marked by said driving mechanism, for actuating said means for automatically stopping said driving mechanism of said truck.
Claim 5
Dependent Claim 73 words
The marking press device as set forth in claim 1, wherein the marking press device further comprises: a plurality of contact leg means mounted upon the sides of said marking press means aNd projecting therefrom toward said plate to be marked for contacting said plate prior to the marking operation and for controlling said auxiliary driving means for assuring the perpendicularity of said marking press means relative to said plate to be marked.
Claim 6
Dependent Claim 43 words
The marking press device as set forth in claim 2, wherein the marking press device further comprises: a plurality of movable marking elements on said marking press means; and means for automatically moving said movable marking elements toward said plate to be marked.
Claim 7
Dependent Claim 25 words
The marking press device as set forth in claim 3, wherein said marking element moving means comprises air cylinder devices supporting said movable marking elements.
Claim 8
Dependent Claim 51 words
The marking press device as set forth in claim 4, wherein said air cylinder devices comprise: air cylinders; hammer devices movably disposed in said air cylinders, and projectable therefrom so as to contact said movable marking elements; and means for supplying compressed air to said air cylinders to drive said hammers.
Claim 9
Dependent Claim 66 words
The marking press device as set forth in claim 5, wherein said means for automatically stopping said driving mechanism further comprises: switch means connected to said retractable contact rod means for generating an operation signal when said retractable contact rod means is retracted; and first circuit means for receiving said operation signal from said switch means and for generating a stop signal to said driving mechanism.
Claim 10
Dependent Claim 43 words
The marking press device as set forth in claim 6 further comprising second circuit means for receiving said operation signal from said switch and for generating a signal to activate said compressed air supply means for driving said hammers away from said plate.
Claim 11
Dependent Claim 59 words
The marking press device as set forth in claim 7 further comprising first timer means for receiving said operation signal from said second circuit means and for generating an output signal for a duration of time so as to activate said compressed air supply means for driving said hammers toward said plate for marking particular indicia upon said plate.
