.'EMPLEMENT FOR LOCKING- PRINTING STRIPS.
I have devised a system of printing wherein embossed strips are removably mounted on a suit-able holder, as for instance on an address plate or a flexible blanket adapted Such plate or blanket has rows of projections which the embossed strips overlie, and on Which they are retained by inwardly turned edge ilanges on the strips extending beneath overle hanging portions of the projections. This provides a simple printing form. It is desirable however, that means be provided to prevent the strip shifting longitudinally on the holder.
The present invention comprises a very simple implement 'for inwardly indenting of the embossed strips to lock them onto their holders to prevent longitudinal shifting. Briefly, the implement comprises a die head 2o having a pair of inclined jaws which engage opposite edges of the strip, and means for delivering a blow on the head' to indent such edges. The means for delivering the blow Vmay well comprise a spring adapted to` be compressed against a retracted hammer which is then suddenly released, to cause the hammer to deliver ablow to theA die and thence to the strip edges.
My invention is hereinafter illustrated in the drawings hereof, and is hereinafter more fully explained and the essential characteristics are summarized in the claims.
In the drawings, Fig. 1, isa longitudinal central section of an implement corresponding to the'present invention; Fig. 2 is a perspective of a portion of a blanket with an embossed strip mounted thereon, showing the implement in position lfor action; Fig. 3 is a diagrammatic view illustrating the implement as first applied to the strip; Fig. 4 illustrates it after the die has impressed the strip; Fig. 5 is a perspective of the strip showing the indenting @Heet of the die.
As shown in the drawings, the die-head 1Q is a small block of metal having at its 'lower end a pair oi' projecting jaws 11`leavin'g a wide groove or channel 12 between them. rlhe inner faces of the jaws are inclined out wardly toward their-free edges las shown in 'j 14, while the outer faces are inclined inwardly, so that the jaws come substantially to sharp or very narrow edges. The distance between the two inclined edges 14 of the 'aws is selected with reference to the width o the embossed strip so that these inclined faces are adapted to engage the edges of the strip and thus a blow on the die will indent the edges of the strip inwardly.
In Figs. 2, 3, and 4, A indicates a flexible blanket, address plate or other supporting member. This plate is preferably of sheet metal carrying on itssurface rows of elevated buttons or projections a, struck up from the plate. Preferably between the projections are corrugations a1, also struck up from the plate. In the direction of the rows, the buttons are connected with the tops of the corrugations but transversely of the row the arcuate edges of the buttons are free from the plate and stand some distance above it. vSuch a plate is more fully described and 'claimed in patents numbered 1,438,584
and,148,582 granted to my assignee The American Multigraph Company, December 12th, 1922, on applications of Wm. J. Demming and Burnie J. Craig respectively.
The embossed strips are indicated by B. Each strip has struck up on it a row o printing characters designated b. The edges of the stripare curled or flanged asin b1. The strips are thusadapted to overlie the projections and be retained thereon by reason of the ianges of the strips extending beneath the overhanging edges of the projections.
As is apparent from Fig. 2, the length of the jaws 11 acting longitudinally on the strip is greater than the distance between the eX- treme points of the buttons ai, so that, no matter in what region the jaws are placed against the strip, they will act on it for a distance sufficient to cause the strip to bind at least against one of the buttons and sometimes against two of them. Figs. 4 and 5 show at b2 the inwardly indented region of the strip which thus binds against the but-4 ton edges. It will be seen from Fig. 4 that the outer surface of the strip, which is normally rounded," has been attened at the jaws complementarily to the jaw surface, while Fig. 5 shows that the indentations extend longitudinally for a considerable distance. I use this terminology considerable distance as signifying an extent sufficient f-to reach from one button to the next.
4The embossed strips are ordinarily made of aluminum and I- have found that a comparatively light blow upon the head is sutibind on the buttons. While the blow must be of sufficient force to effect the indentation, it should not be excessive, as that might otherwise distort the strip. Accordingly, it is desirable to provide means for delivering a const-ant blow. I have found it very satisfactory to provide a hollow handle in which the shank of the head is slidably mounted and provide in'this handle a slidable hammer block acted on by a spring which is compressed rvwhen the handle is shoved inwardly and then suddenly ,released to cause the hammer to deliver a constant blow to the die head. Such mechanism is shown in Fig. 1 and will now be fully described.
In Fig. 1, 20 indicates the barrel of a handle which is closed at its upper end by a -suitable cap 21, having a threaded extension 22, screwing into the end portion of the barrel. At its lower end, the barrel has an internal thread 23, in which screws a reduced extension 24: on the hammer guiding portion 25 of the handle. The die head 10 has a shank slidably mounted in this handle extension 25'. I have shown the head 10 as having a threaded stud 15 screwing into a l rod which in operation constitutes 'a rigid the handle.
tshankfor the head. This shank is slidably' mounted within the handle portion 25 and held in the extended position shown in Fig.
1, by means of the comparativel light compression spring 4() which lies wit 1in the bore 26, around the portion 35 of the shank and bears at its lower end against the collar 31 and its upper end against a slidable impact block or hammer to be described. Above the` shank portion 35 is a reduced portion constituting an axially extending pin 37, and the hammer has an axial bore which loosely surrounds the pin. This hammer is freely slidable within the barrel 20. It has a lateral recess 41 in which is mounted a dog 52 adapted to overhang the top of the shank pin 37. This dog is normally pressed inwardly into this position by a spring 53 carried by the hammer, and thus retains the hammer in raised position.
The bore 55 of the hammer which, as stated, is occupied by the shank pin 37 below the dog 52 is also occupied above the dog by a pin carried by and projecting inwardly from the stationary head 21. A comparatively stil' compression spring 70 occupies the space between the hammer and the head 21, being mounted with ythe barrel and around the pin 60. The pin 60 normally stands some distance above the dog 52. This dog has an inclined inner face as shown in 57 which may be engaged by the inner edge of the pin 60 and cammed backwardly thereby to clear the shank pin 37.
In use, the implement with the parts in position as shown in Fig. 1, is placed over the strip to be indented with the jaws engaging opposite edges thereof, and then the handle is pressed downwardly toward the strip. In this movement the hammer cannot move downwardly because the dog 52 engages the top of the shank extension 37, thus providing a continuous rigid strut from the embossed strip to the compression spring 70. Accordingly, this downward movement compresses this spring until the pin (50, moving inwardly in the bore 55 of the hammer, engages the incline 57 of the dog 52 and cams that dog outwardly to clear the shank pin 37. As soon as this takes place the hammer is free to move and is forcibly moved downwardly by the compressed spring 70, thus delivering a sharp blow against the shoulder 38 where the shank pin 37 joins the larger shank pin 35. This blow is delivered through the shank to the die head and thence to the embossed strip. In this movement the spring 40 is incidentally compressed a small amount, but this spring is light enough, so that it opposes no material resistance.
It will be seen that the operation of the tool is very simple. It is grasped in the hand and placed with the jaws in the opposite sides of the embossed strip and the handle placed toward the stri until the indenting blow is delivered to t 1e strip. The inward incline of the outer edges of the jaws enables these jaws to engage a strip even though another strip is mounted very close to it, as illustrated in Figs. 3 and 4. The width and depth of the groove 12 in the die head is snflicient so that it clears the embossed characters on the strip so that they cannot be injured by the operation. I have found that these indenting blows, delivered by a constant spring force, on the edges of the strip, while they distort the edges inwardly sufficiently to bind on the buttons have no effect in bending the intermediate portion of the strip, and thus do not in any manner distort or interfere with the printing characters on the strip.
Attention is called to' the fact that my applicationvNo.v 50,155iled August 14, 1925 and now issued as Patent No. 1,651,185, which is a continuation in part of this application, claims the method of binding strips on their holders as illustrated herein by means of delivering blows to their edges to indent such edges without disturbing the printed surface. Such method may be carried out with the assistance of the implement of the present application or by other devices.
Having thus described my invention, I claim l. An implement of the character de scribed comprising a barrel, a movable hainmer therein, a compression spring adapted to act on the hammer, a head having a pair of separated jaws having inclined inner faces adapted to engage opposite edges of an embossed strip, and means whereby inward movement of the barrel first compresses the spring, while the hammer is locked and then eleises the hammer to deliver a blow to the lea 2. In a device of the character described, the combination of a die head having a pair of separated jaws witht-heir inner faces inclined outwardly toward their free edges, the outer faces of said jaws being inclined inwardly toward said edges, and means mounted in the device, but movable with reference to the die head for delivering a blow to the die head.
3. A device for indenting the edges of a Strip comprising a head having a pair of projecting jaws rigid thereon, said jaws having their inner aces inclining outwardly toward vthe free ends of the jaws, and the outer faces o'f the jaws inclined inwardly toward their free edges, the outward and inward incline of each jaw coming substantially to a line at the edge of the jaw.
4. In a device of the character described, the combination with a shank, of a head having a pair of rigid jaws located parallel with each other and some distance apart, the length of said jaws in the direction of parallelism being greater than their distance apart, whereby a single pair of jaws may simultaneously engage two round buttons spaced apart and located in the saine plane.
5. An indenting device adapted to bind a flangedsurmounting strip on a holder having a row of spaced projections with overhanging edges, said device having opposed jaws with inclined faces adapted to engage an edge of the strip for a distance at least as great as the distance between corresponding points on two successive projections, which distance is at least as great as the distance between the jaws.
In testimony whereof, I hereunto affix my signature.
