. HDATE-FEEDING MECHANISM FOR ADDRESSING-'MACH'INES.

To all whom it may concern:

Bait known that we, -CHARLES Owens and ALEXANDER Lynn, citizens of the United States, residing at Chattanooga,.Tennessee, have invented certain new and useful Improvementsin Plate-Feeding Mechanism for Addressing-Machines, of which the following is a specification.

The invention relates to addressing machines wherein is used a series of printing or drum to be conveyed thereby to the im- 'pression platen to be there imposed on the magazines or'other package for applying the address thereto.

'llheinvention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings: Figure 1 is a side view of the mechanism embodying the invention, this view showing the printing plate or stencil feeding mechanism during the operation of feeding a printing plate from beneath a pile of plates in the hopper to the carrier or drum of the addressing machine. Fig. 2 is a view similar to Fig. 1 with the parts in a different position. Fig. 3 is an end view of the parts shown in Figs. 1 and 2. Fig. 4 is a view of a detail.

In these drawings 1 indicates a hopper arranged over the drum or carrier 10 of the addressing machine in position to supply the printing plates thereto by gravity. To this hopper frame are pivoted arms 2 constituting the plate holding and separating devices, these arms having notches as at 2 at their lower ends to engage the edges of the printing plates.

Specification of Letters Patent.

Application filed October 19, 1907. Serial No. 398,257.

3 indicates a pressure cam there being preferably two of these one at each end or side of the hopper as shown in Fig. 3. These cams are designed to press down or start the printing plate into connection with the drum or' carrier 10 and more definitely. speaking, into the recessed portlons 10 of said carrier or drum, and they act also to hold the'plate within these recessed portions. These camsare pivoted at t to the supporting and plate holding arms 2. They Patented J an. 25, 1910.

tion. one of these springs is shown in -F 2 but omitted from Fig. 3. Attached to the plate holding and supporting arms 2 are levers or arms 7.

In connection with the drum -or carrier, gripper means for the printing plates are employed, these being substantially similar to the gripping mechanism disclosed in Letters Patent of the United States granted to Charles Owens and Alexander Lyle #889,328, June 2, 1908. Upon this gripper device shown generally-M8 is mounted a roll 9. Arms 12 are pivoted at 13 to the (hopper frame carrying at their lower ends a roll 14. The pile of printing plates within .the hopper is indicated at 11 the rear portion of this pile resting upon a stop 15.

The plate holding arms 2 having the notches in their lower ends are arranged so that these notches are at such a distance from the drum when the raised or beaded portion 10 of the drum is beneath the hopper or the pile of plates therein, that these notches engage the first plate above the bottom plate leaving the advanced edge of the said bottom plate lying loosely on 'the raised or beaded portion of the drum 10. This raised or beaded portion is the same as that disclosed in the application above referred to these beads on the drum fitting closely beneath the hopper sustaining the lowermost printing plates of the pile until the recessed portion as 10 10 comes around beneath the hopper. When the raised or beaded portion of the drum is in action beneath the hopper the cams 3 are held away from the pile of plates by these raised or beaded portions of the drum or carrier which act as a track or camway for the said cams. As the drum advances and the recessed portions 10 10 come beneath the pile of plates the advanced edge of the bottom plates drops into the forward recess 10, and at the same time in view of the formation of this recess the cams 2-) swing downwardly over the top of the edge of the bottom plate as shown in Fig. 1 and between it and the pile of printing plates above, the rest of the pile being susare pressed by springs 5 into working position thatis, in a direction toward the hopper. The plate holding and supporting arms 2 are pressed by springs 6 into normal posit l l tained by the plate holding and supporting arms 2 at the front pile, the rear edge of the lowermost plate being held up with the rest of the pile by means of the stop or support 15, as shown in Fig. 1. As-the drum'orncarrier continues its rotary motion the cams 3 follow this movement with. the plate and drum against the tension of the springs 5 until a point is reached where the cams begin to clearthe printing plate when said plate passes beneath the cams under pressure and until the forward edge of the plate is engaged by the roller 14. At this moment the gripper devices are caused to travel across the face of the drum and engage the printing platel The lowermost plate of the pile having now been placed upon the drum it will be understood that the pile of plates is supported by the stop'15 in the bottom of the hopper l and the plate holding and supporting device 2 which withtheir notches engage the lowermost plate. As soon, however, as the drum advances far enough for the roller 9 to strike the lever 7 the forward edge of the pile of plates is released by the devices 2'and allowed to drop down upon the raised portion or bead 10 of the drum and as soon as the 1evcr'7'is released from the roller 9 by the onward movement of the drum these plate holding or supporting arms fly back into'normal positionvunder the action of their springs 6 and they engage the forvard edge of the plate next above the bottom plate thus separating the forward edge of the bottom plate from the pile above ready to be fed when the next recessed portion 10 of the drum comes into proper posilow up this forward movement-of the drum and further that these cams or presscrs by riding over the plate which had just been taken from the pile will seat the same firmly in the recesses of the drum and this action will be aided by the action of the roller it until the gripping of the plate is fully arcompl-ished, the parts then being in the position shown in Fig. 2. It will be observed that there is a recess 10 to receive each thickened edge of the printing plate and the portions of the drum between these recesses being raised relative thereto Furnish a raised or backing-surface upon which the body of the plate may rest to be supported thereby when this plate is imposed upon the magazine to apply the address thereto. The recess'es 10 provide in effect, shoulders or proi jections-adapted to engage orgrip the inner edges of the thickened margins of the printing plates .80 that when the forward edge of a printing plate drops down as shown in Fig. 1 it is gripped the shoulder formed by the recess and the continued movement of the drum will cause this shoulder actlng on the thickened margin, to draw the printing plate from beneath the pile and off from the supporting ledge 15. This action is, of course, aided bythe presser 3. Thedrum is representative of any suitable feeding element or carrier for the plates.

It-will be observed that in the operationof our machine comparatively stiff plates are employed having type surfaces thereon; These plates are not dragged from the bottom of the pile, but are separated at their front edges from the bottom of the pile to drop down so that the type face of'the plate which is dropped will be entirely clear of the plate next above it, and not until then is the low-- ermost plate moved forward by the carrier from the hopper. In this way the plates are not damaged, and their type surfaces are not subjected to undue wear in the feeding action.
