his invention relates to a machine for removing printing strips from a holder thereof, and at the same time restoring to proper position displaced portions of the holder. More particularly, our machine is adapted to act on embossed strips of metal which overlie raised projections on a stamped metal holder. The strips underhang such projections and must engage them with suficient tightness so that they will not become displaced in use. It is desirable however to remove the strips of any obsolete address plate so that the holder may be used for a fresh address, and our machine is adapted to effect such removal expeditiously, notwitl standing the normal tight engagement of the strip on the holder.

Now in effecting the tight engagement of the strips in the holder the projections of the latter are sometimes distorted from their normal position, and they are likewise sometimes displaced by the action of the strip as it is being removed. The present machine as it removes the strips from such holder, is adapted to restore any displaced projection, so that the stripped plate is, at once, in condition for receiving fresh printing strips.

Our invention is in the nature of an improvement on Patent No. 1,644,773 of iVilliam J. Demming, granted October 11th,

1927, to the assignee The American Multigraph Company for an apparatus for removing printing strips froin holders. The Demming machine however is a hand operated device, and it has been found that if the printing strips are tightly pinched onto the holder projections, too much power is required in stripping them to enable a hand machine to be rapidly operated.

A preferred embodiment of our invention is illustrated in the drawings, and is hereinatt-er described in detail, and the essential novel features of the invention are summarized in the claims. Y Y

in the drawings, Fig. 1 is plan of our improved machine; Fig. 2 is a vertical longitudinal section of the same; Fig. 3 is an end view from the right hand end of the machine shown in Figs. 1 and 2; Fig. 4 is an enlarged vertical cross section parallel with Fig. 3,

the plane being indicated by the line 4-4 on Fig. 2; Fig. 5 is a fragmentary perspective of a portion of the plate feeding slide; Fig. 6 is a perspective of a plate which our machine is adapted to strip and true; Fig. 7 is a perspective of one of the stripping plungers with the truing device carried thereby; Fig.

As shown in Figs. 1, 2, 3 and 4, the frame of the machine comprises a suitable bed 10 with a narrow fiat top, merging in the right hand portion with downwardly curving sides 11 and 19.. This 'frame also has a substantially vertical end plate 13 and various cross Webs as 14, 15, 16. The curved sides 11 and l2, and the end plate 13 and web 14 terminate at their lower extremities in feet 17 to support the machine in a horizontal position. As shown in Fig. 3, the machine rests on a suitable stand indicated at 20, to which the feet 17 are bolted.

In the narrow flat top of the bed 10 is a longitudinal channel 18 extending from one end of the frame to the other end of a width somewhat greater than that of the address. plate to be stripped. This channel 18 near the right hand end of the machine is covered by a plate 19. Slightly at the left of this cover plate and over the open channel 18 is theV plate magazine 40, and beyond that the Vstripping fingers to Vbe later described. Y

Longitudinally siidable in the lframe channel 18 is a slide comprising a pair of longitudinal bars 30 spaced apart, and two interi mediate- blocks 31 and 32 which lie,V between the bars and!Y are held rigidly to them by screws or pins 34 and 35.,V The block 32 lies` above the bars 30 andhprovides a saddle for.V

\ To reciprocatethe frame 30, 31j, 32 by'powf er, we provide the cam drum 50 having its shaft l'journalled in the end plate 13 and roller 38 onl a ,studi 39V depending from the` l bloclr 31 ofthe reciprocating frame. Thisv cam groove makes a complete' circuit about the drum from a region .ne'aron'e end of the drumv toV a'vregionnear the` other end sothat one rotation ofthe drum gives a complete recipro-U cation forward andbaclrtothe slide.

It results from the construction described, that when the reciprocating slide islnio'ved to its extreme outward kposition bringing the saddle block 32 beneaththe-magazine Ll0, the

v stackof plates drops so that Vthe beadsV of the bottom plate come into recesses 36in the bars in opposite sides ofthe saddle block;'then as -the .slide movestoward vthe left (Fig. 2)' the l shoulders 37 at the' right hand end of such recesses lshove the bottom-'most plate toward theV left, while themagazine members @retain alll of the'addre'ssplatesveXcept therbottonimost plate.

' rNear the right of the magazine, as shown inFigsQ1'and'2 is a transverse block 70 secured to' the bed by, screws passing through theblock. On its under side, this block is recessed at 7 2 to allow the passage of the recip- Y rocating frame and plate.. 'Mounted in a .recess 73l in the left handverticalface -ofthe block are a set of plungers 8O (as many as the total number oflines'which'may be carried to thel plate) which4 are shown as separated by webs 71 of the block and held in place by a frontplatei secured tothe block 7() and havingan overhanging top flange 76; Any of these plungers vmay be held in place toengage the correspondingstrip and preventits advancement vwhile the plate is adf vanced beneath the block. 2 Mounted in .lcerfs 77 vinV the upperface of the bloclr() are series of levers 85 pivoted by means Aofa.transversepin 86.V There is one in the block 70 are short latchrods 78, one for eachplunger 80, and pressed toward the-1n Vby springs 79. The plungers 80 are provided withsuitable V-shaped recesses82 inwhich tive, it is substantially in the position shown in 8 and 1G, the latch 78 engaging its notch` 82 and holding it in place. lien, however, it is desired to move any plunger idle position, this is readily etlected by depressing the outer end of the corresponding lever .75 which moves the plunger upwardly until it abuts the iiange 76 of the front plate. The spg latch engaging the tace of the plunger will hold it in this elevated idle position until the plunger is depressed by its lever.

Assuming that the plungers are depressed to engage the strips to be removed, then as tie reciprocating :trame carries a plate toward the right out or" the magazine, the plungers will engage the strips without engaging the plate and thus prevent advancement ci the strips. so that the plate is shoved out beneath the strips. The plate is thus adlvanced beyond the plungers and is thereby cleared of such strips as it is desired to remove, the removed strips dropping through an opening in the bed.

Fig. 12 illustrates at ZJ an indentation ot the edge ilange b of a printing strip B by a comparatively narrow tool which maires au indentation li coming between two plate-lips o, and on the opposite sine an indentation h2 coming against a single lip. As there is less resistance to the indentation between the lips, the most of the strip-distortion takes place on that sine, resulting in a considerable inward bend. This inward bending no only requires relatively large power to remove the strip from the plate, but has a camming action on th lips of the plate as the stri is l emp' removed, thus frequently distorting eral ot those lips.

The distortion oi the plate by the camming action of the strip being removed, as just reierred to, may to a certain extent be relieved by lengthening the indentation as illustrated Fig. but in this case, assuming that in indentation is long enough to bridge the difierence between one lip to the next, the inl.. ation is comparatively slight on the side where the two lips are engaged but is greater on the other side where one lip only is engaged, e lip is with the result that the si A f bent inwardly by the act orn distorting the `strip as indicated in Fig. 14.

This indenting of the printing strip may be eiiected in any suitable manner, as Jfor instance by the hand tool shown in Patent No. 1,720,318 granted July 9th, 1999, which operates on each strip individually, or the multiple acting` power machine oi Patent No'. 1,734,707 granted November 5th, 1929, both its 'to the assignee The American Multi- Company. But however, the indentations are applied, or whatever their form, the ultimate result on the plate is substantially the san e; namely the retention is so edective that much power is required for removal of the strips, and after a strip has been removed, several lips on the plate are so distorted from true position, that it is not feasible to slide a fresh printing strip onto the plate. We have, therefore, provided means about to be described to true the lips oit any row as the strip of that row is being removed.

Mounted on the Leshaped lower end 95 oi each plunger S0 is a stirrup 90. This stirrup has inwardly projecting` bottom flanges 91 a suitable distance below the bottom :tace 86 oi the plunger, so that the plate projections it properly positioned may readily slide between the two. As the plate lips may be distorted sideways as well as up and down, we taper of the end of the flanges 91 laterally as shown at 92 in Fig. 15, while to lift depressed lips we taper the upper surface of these flanges as shown at 93 in Fig. 8. Such downwardly extending bevelled portion is adapted to slide beneath any distorted projection as indicated at at in Figs. 8 and ll, and raise it to the proper level as indicated by the projection a3 in Fig. 8. Accordingly, the mere act of discharging a strip troni the plate au* tomatically trues any distorted projection.

Tt should be noted that in the truing action described, the truing stirrup is entirely stationary, while the plate is positioned while being delinitely guided parallel with the truing flanges 91. This guiding action of the plate-propelling slide is ot importance in insu ing accurate operation oiE the truing flanges. The under lace oi' the plunger 8O terms top abutment limiting the upward bending of the lips, by the bevels 93. These lips therefore come into the coniining channel provided by the under face of the plunger and the upper horizontal face of the flanges and the vertical inner sides of the stirrup, which necessarily produces a true lip as the same passes out ot this guide.

The address plate which the particular embodiment shown is designed to strip has its intermediate region arc-shaped so that it may be readily mounted for printing action on a rotary drum. To enable the truing flanges 91 to properly engage beneath the plate lips of such a plate, while the under face 8G oit the plunger 80 stands close to the top of those lips, we mount the plungers 89 radially about the same center as that 01": the arc of the plate, as shown clearly in Fig. 10. To accommodate these radially positioned plungers, we malte the grooves 74 in the block 70, which they occupy, radial as shown in Fig. 9.

As the machine operates with considerable rapidity, momentum tends to carry the stripped plate to some extent beyond the end oi the saddle 32; as the slide reaches the end of its stroke; then as the slide reverses its movement and moves in the opposite direction, the inertia of the plate tends to hold it pulls out from under the plate. These two forces of momentum on the strippingstroke and inertia on the return stroke are ordinarily sufficientA toentirely 4discharge the plate f so'that it passes downed .the endof Ythe bed intothe receptacle 100. However, if for any `reason the plate remainson the saddle, no
