Abstract
Abstract This invention relates to a stand-alone electronic mailing machine. The entire drive mechanism, setting mechanism, and control devices as well as the postage metering mechanisms are all contained in one housing so that there is no need for a separate base. In the mailing machine of this invention, a reciprocating platen is used for the purpose of driving an envelope against a print head during the applying of postage to the envelope. A stripper is resiliently mounted on the platen to assure the envelope does not adhere to the print head.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A mailing machine for printing postage upon an envelope, comprising: a housing having a slot therein, a platen movably located within said slot, said platen comprising a frame and a resilient member attached to said frame, a print head spaced from and facing said platen resilient member, means for moving said platen toward and away from said print head, a stripper bracket movably attached to said platen frame, spring means secured to said platen frame and in engagement with said stripper bracket to bias said stripper bracket away from said frame, thereby providing means for removing an envelope that may adhere to said print head as said platen is driven away from said print head.
Claim 2
Dependent Claim
115 words
A mailing machine for printing postage upon an envelope, comprising: a housing having a slot therein, a platen movably located within said slot, said platen comprising a frame and a resilient member attached to said frame, a print head spaced from and facing said platen resilient member, means for moving said platen toward and away from said print head, a stripper bracket movably attached to said platen frame, spring means secured to said platen frame and in engagement with said stripper bracket to bias said stripper bracket away from said frame, thereby providing means for removing an envelope that may adhere to said print head as said platen is driven away from said print head.
Claim 3
Dependent Claim
120 words
A mailing machine for printing postage upon an envelope, comprising: a housing having a slot therein, a movable platen located within said slot, said platen including a frame and a resilient body supported within said frame, a print head supported by said housing so as to be spaced from and facing said platen, means for moving said platen toward and away from said print head whereby said resilient portion is engageable with said print head, a stripper bracket movably attached to said frame, said stripper bracket having a first portion slidably mounted on said frame and a second portion that extends between said platen and said print head and spring means for biasing said stripper bracket away from said platen.
Claim 4
Dependent Claim
120 words
A mailing machine for printing postage upon an envelope, comprising: a housing having a slot therein, a movable platen located within said slot, said platen including a frame and a resilient body supported within said frame, a print head supported by said housing so as to be spaced from and facing said platen, means for moving said platen toward and away from said print head whereby said resilient portion is engageable with said print head, a stripper bracket movably attached to said frame, said stripper bracket having a first portion slidably mounted on said frame and a second portion that extends between said platen and said print head and spring means for biasing said stripper bracket away from said platen.
Claim 5
Dependent Claim
234 words
A mailing machine for printing postage on an envelope, comprising: a housing having a slot therein, a switch located within said slot, a platen arm having one end pivotally supported within said housing and a second end extending into said slot, a platen having a frame and a resilient member supported by said second end of said platen arm, a print head spaced from and facing said platen, a stripper bracket movably attached to said platen frame, said stripper bracket having a first portion movably attached to said platen and a second portion that extends between said platen and said print head, spring means secured to said frame and in engagement with stripper bracket to bias said stripper bracket away from said frame, a clutch supported within said housing, means connecting said clutch to said platen arm, a motor supported within said housing, clutch activating means for providing engagement between said clutch and said motor upon said switch being actuated, whereby upon an envelope being inserted into said slot said switch will be closed and send a signal to said clutch actuating means to engage said clutch to said motor thereby providing drive to move said platen into and out of engagement with said print head, said second portion engaging an envelope that may adhere to the print head and remove the same therefrom as said platen is moved away from said print head.
