Way, Cleveland, Ohio, assignor to Multigraph Company, Wilmington, Dcl., a. corporation of Delaware Application October 5, 1931, Serial No. 567,004 Y 14 Claims. (Cl..15339) I This invention relates to an apparatus for use in the formation of address plates, and is particularly concerned with mechanism for curling the edges of such plates to form protecting beads i thereon. The address plate formed by. the ma-- chine may be of the type shown, described and claimed in Patent No. 1,628,630, granted May 10,192? to my assignee, American Multigraph (20., as assignee of Henry C. Osborn- Such address plate is of inverted trough shape,.having an intermediate region formed of rows of upstanding overhanging projections on which may be mounted embossed .printing strips having flanges at their edges which overhang the projeotions.

The invention, which comprises the beadforming means above referred to, is hereinafter more fully described in connection with the drawings, which illustrate a preferred embodiment thereof.

, In the drawings, Fig. l is a vertical section 86 through a machine of the punch-press type, having my bead-forming mechanism; Figs. 2 and3 are vertical central sections of the same, showing the parts in different positions; Fig. 4 is a vertical section in a plane parallel to the Fig.

As illustrated in Figs. 1] to 6, my machine provides a bed ,plate 10 from which'rises suitable standards l1 and 12 in which is journalled 0 a transverse rotary power driven member 20 which, by suitable means, actuates a head 30 reciprocable vertically between the standards 11 and 12. Thegrotary member may be operated by a belt, pulley 21 forming a portion thereof, and it may communicate motion in any desired manner to the reciprocating head 30. By way of illustration, I have indicated a Scotch yoke connection betweenthe rotary member 29 and the reciprocating head 30. The yoke 0 is indicated atf35, and has a horizontal slot embracing the pin 22 of "the double crank 23. The yoke has a shank 36 which is shown as extending loosely through a cross bar'37 of the head and into a boss 38 thereof. A suitable nut 39,. threaded on the shank between the parts 37 and 38, provides an adjustment. The mechanism described may be conveniently mounted on some suitable stand as indicated at 15 in Fig. l.

Secured on top of the bed plate 10 beneath 8 the head 30 is an anvil 40 curved on its upper surface to properly support the blank. indicated at A in Fig. 9. At the left-hand side of' the machine is a magazine 50 adapted to carry a number of these blanks, one above the other. 35 Suitable mechanism is provided, operated by the rotary member'20; for shoving the bottommost blank onto theanvil. To effect the feeding of the blanks, I have shown, in Fig. 1, a reeiprocatory slide 52 resting 0 on a frame plate 16 which forms the bottom the anvil to advance the bottomniost plate in the stack'onto the anvil and shove the blank that has been acted on off of the anvil. In such movement, the blank is properly discharged into a suitable receptacle by a mechanism hereinafter explained. i

width of the blank, asindicated by the openings 17 and 1 8"through which the blanks travel to and from the mandrel. Extending. transversely across these openings and secured to the standards are horizontal blocks 60 andfil which have, on their inner faces, tongues 62 These llc beads.

tongues loosely occupy notches in a clamping block 65 adapted to rest on top of the blank on the anvil and be pressed down firmly against the blank, by means hereinafter described, to hold it in place during the curling operation. Until the pressure is applied, the block 65 rests on top of the address plate by gravity. The lefthand edge of the block is beveled or rounded as indicated at 67 in Fig. 4, to enable the blank A to be readily shoved under the block.

Secured to the underside of the cross block 60 in the standard 11, are a pair of blocks 71, each of which has projecting from its bottom a round horizontal rod '70. These two rods are spaced apart a distance corresponding to the troughs a formed at the edges of the blanks A, so that, as the blanks are shoved by the feeding mechanism onto the anvil, the two troughs a embrace the rods 70, which are adapted to act as mandrels for the subsequent curling action of the plate edges. Suitable strips, as 74 and 75 (Fig. 6), are set into the block 60 and the base of the standard 11 to form guides for the outer edges and bottom of the blank troughs a so that, when the blank is advanced, these troughs will be accurately guided into position about the mandrels.

Immediately following the placing of the blank on the mandrel, the clamping means heretofore mentioned comes into action to press this blank down on the mandrel. The pressure is yieldingly supplied by a plunger slidably mounted in the head 30 and yieldingly supported by a compression spring 81 holding a guide shank 82 on the plunger. For convenience, the plunger and its spring and shank are mounted in a separate plate 85, rigidly secured to the under face of the head 30, acting as a unit therewith.

It will be apparent from the above descrip tion that the first action of the downward movement of the head 30 is to bring the plunger 80 into engagement with the block 65 to cause it to clamp the blank under spring pressure. Then, the mechanism about to be described, acts to curl inwardly the upwardly projecting edges of the blank about the mandrels to form complete beads.

The mechanism for automatically curling in the edges a of the plate is illustrated in Figs. 2, 3 and 8. It comprises a pair of blocks 90 pivotally mounted near their lower ends, as by rods 91 extending through the blocks and into cars 45 on opposite sides of the anvil 40. Each block 90 is formed with a recessed jaw 92 having an inwardly and'downwardly curved face, the radius of the curvature being substantially that which is to be given to the bead of the plate. The upper surface of the block is inclined downwardly and outwardly, as shown at 93, and behind the base of the bottom of the incline is an upwardly projecting 7 portion 94. Suitable springs 96, mounted in facing cavities in the blocks 90 and the edges of the anvil 40, tend to spread the blocks into the position shown in Fig. 2. They are normally retained in this positionby stop blocks 97 behind them secured to the bed 10.

I form, on the reciprocating head 30, means to coact with the surfaces 93 of the blocks 90 and cam them inwardly to effect the curling of the These camming members on the head are preferably in the form of blocks 100 (Figs. 2 and 3) which are secured to the underside of the plate which is rigidly mounted on the under face of the head 30. Each block 100 has a downwardly inclined projecting portion 101 to engage the cam face 93 of the pivoted block, and behind this projection 101 is a suitable recess 102 to receive the wing 94 of the block. The blocks 100 are shown as secured to the plate 85 by screws 105 and as bearing, at their outer faces, against plates 87 secured to the plate 85.

When the blank A is shoved onto the anvil by the feeding slide, the curling parts are in the positions shown in Fig. 2. Then, as the head 30 descends, the projections 101 engage the cam surfaces 93 and force the curling blocks inwardly into the position shown in Fig. 3. This action causes the jaws 92 to engage the upstanding free edges or of the plate and bend them inwardly about the mandrels 70.

It should be noted that the jaws 90, in their active operation, are swinging slightly downwardly, as well as inwardly, due to the position of the pivots of the blocks, so that the edge a is completely curled into contact with the mandrel and the end of the edge comes substantially into contact with the downward portion leading from the body of the plate, as illustrated at a in Fig. 11. Due to the mandrels and the peculiar action of the curling jaws, the troughlike edges a of the blank are made accurately cylindrical. Thus a definite outside vertical diameter, indicated in Fig. 11 by X, is obtained for the bead; also, the exact extreme width of the plate indicated by Y is maintained. This is important in the subsequent use of the plate in addressing machines.

On the up stroke of the head 30, the curling jaws 90 are freed and swing outwardly under the action of the springs 96, and thus the completed strip holder is left resting on the anvil with its beads embracing the mandrels. This up stroke of the head serves to advance another blank from the magazine 50, and this blank, abutting the completed plate, shoves it to the right (Fig. 1) nearly off of the mandrels. In this travel, the completed plate is guided by the vertical strips 110 (Figs. 1 and 8), and at the end of the stroke is supported partly by the end portions of the mandrels and partly by the pivoted packer 112 which engages the underside of an intermediate region of the plate. The same upstroke which shoves the completed plate between the guides 110 and onto the packer, operates the packer to further advance the plate and send it down into a receiving box or support indicated at 115.

The desired swinging movement may be given to the packer by a linkage mechanism connecting it with the reciprocating head 30. For this purpose, I have shown an arm 116 secured to the head and connected by a link 11'? to a rock arm 118 rigid withthe packer 112. A suitable slot 119 in the link 117 allows a free movement so that the packer acts at the end of the up stroke of the head.

It will be understood from the description given that blanks, contained in the magazine 50, are automatically acted on one afterthe other, and delivered in the form of completed members with tubular edges, as shown in Figs. 12 and 13.

In the specific embodiment illustrated, the blanks are of the form shown in Fig. 9, and the completed members having rows of upstanding overhanging projections a which were preferably formed on the blank A, and these projections are adapted to receive and hold embossed printing strips as indicated at B in Fig. 14. But while I have shown the address plate as consisting of the holder having upstanding projections carrying separate embossed printing strips, it is to be understood that the printing faces may be carried by the plate in any manner, and the plate itself might be embossed as is well understood. The machine of this invention which curls in the edges of the troughs on the blank, with very slight changes would be equally operative with quite different forms of address plates. I therefore do not intend to confine the present invention to the formation of the plate shown.
