Abstract: 330,998. Triggs, W. W., (Spiegel's House Furnishing Co.). March 27, 1929. Addressing and like machines, - A machine for handling cards, stencils, or like articles, comprises a magazine having upper and lower parts which. are tiltable one relative to the other and are adapted in their normal positions to form a vertical guideway for the articles with an outlet adjacent its lower end, and a shelf in the movable part of the magazine which is movable into the guideway above the outlet for temporarily supporting certain of the articles, and which may be withdrawn from the guideway to permit the articles to drop towards the outlet. Mechanism for feeding the stencils to printing position is also described. As shown applied to an addressing-machine, a stencil magazine comprises a base 12 and an upper part 13, which is pivoted at 36 to the base 12, and consists. of a front part 37 and a rear part 38 hinged like a gate to the part 37. A shelf 45 provided with a handle 51 is slidably mounted on the part 13 by means of a slot 46 engaging screws 47, 48, and is moved into the magazine when the pile of stencils falls below the part 13. The gate 38 is then opened, a tray of stencils is inserted and is supported on the shelf 45, the part 13 is swung down until a stop lug 43 thereon meets the base 12, the tray is removed, the gate 38 is closed, and the part 13 is returned to normal position, the magazine having thus been refilled without interruption of the working of the machine. The gate 38 is retained in the open and closed positions by means of a projection engaging notches. and is released by raising the gate against the action of a spring fixed to one of its hinged pins. The part 12 is mounted on inclined rails 14 so that the magazine is tilted forwardly and the stencils fall towards an outlet 25, the width of which may be regulated by means of a gate 28 secured in adjusted position by screws passing through slots in a bar 26 across the front of the magazine. Angle brackets 34 fixed in a similar way by screws 32 to the bar 26 guide the stencils as they leave the magazine. Openings 24 are provided in each side of the base 12 to allow the fingers to be inserted to adjust the stencils should they become jammed. The stencils are ejected from the magazine into a lateral guideway by means of a reciprocating pusher 62 to which is fixed a lower plate 65 supporting the removed stencil and having prongs 66 bent up to engage holes in the stencil. The lateral guideway comprises rails along which the stencils are moved to printing position by a conveyer chain 5 having projections 7 engaging the holes in the stencils. The pusher 62 is carried by a block 63 fixed to a rod 70 connected to a pivoted arm 81 oscillated by a rod 82 connected to a crank pin on a rotary disc 83. The rod 70 comprises a tubular part within which the reduced end 72 of a rod 71 is slidable. A spring 74 pressing the parts together yields and prevents damage if, during the operative stroke, the stencil becomes jammed. The cam 83 also actuates an oscillating arm 85, the forward end 89 of which engages the side of each stencil as it is ejected and raises it into the plane of the guideway.
