Time card recorder

Claim 2

The combination of an open time recorder mechanism, a locking panel and a casing to enclose and protect same, in which the casing is completely closed except for an open front large enough for the time recorder mechanism to pass through, said open front provided with a raised and inwardly turned lip along the lower edge, said inner rear wall of said casing provided with a springbiased circular bar against which the recorder mechanism bears when mounted, said base of said casing provided with a locking element positioned centrally adjacent the open front, said front edge of said recorder mechanism abutting said inwardly turned lip to retain and position said recorder mechanism and a single threaded bolt with a grooved base element mounted horizontally through the bottom of said card slot and extending to a position to abut with said locking element, said bolt turned to take up the grooved base element until the locking element is engaged to tightly retain the recorder mechanism to the casing and said locking panel mounted in said open front above said card slot and locked to said casing.

Claim 3

In a device according to claim 1 in which said time recorder includes a card slot that includes a plurality of switches that are closed by pressure of the card thereon, said card slot positioned adjacent and in front of a card carriage, said card carriage including a card-gripping cam lock to grip the edge of said card when it is inserted through said card slot, said switches in said card slot when closed energizing through a circuit the operation of a motor, said motor rotating a cam that bears against a lever to control the movement of said card carriage and said carriage bias in one direction of movement by a spring, a normally closed switch means in said circuit that is opened when said card carriage reaches a printing position, a continuously operated clock printer that is actuated when said card is in the printing position, and a card-ejecting switch to energize said motor and by means of said rotating cam move said card carriage toward the card slot to eject said card, and a cam driven by said motor to break said circuit when said card carriage reaches its extreme ejecting position and an automatic mechanical cam release released at the fully extended forward position of the card carriage to release the card-holding cam lock.

Claim 4

In a device according to claim 1 in which said time recorder includes a removable printing wheel mounted on one side of a pedestal and includes a central pivotal shaft mounting for rotation of said wheel, a slot cutout slightly less than the radius of said wheel and a retention spring fastened to the pedestal side of said printing wheel and passing over said wheel to bear against the side of said wheel opposite to said pedestal, said retention spring being of a size less than the slot cutout to permit removal of said wheel when the spring aligns with said slot.

Claim 5

In a device according to claim 3 in which the face of said wheel away from said pedestal includes stops that mate with a projection on said retention spring and also align with printing indicia on the circumference of said wheel, means to set said printing wheel at any desired stop for printing the preselected indicia and manual means to release said retention spring and rotate said wheel to align said slot with said retention spring to remove said printing wheel.
