making wire bound box blanks of that kind in which the sections of the blank are reiny forced by cleats.

Among other objects my invention is intended to provide a machine of such character that the blanks can be made in diiferent ways, as by using loose spacing blocks between the ends of the cleats, or without employing any spacing blocks at all, whereby cleats of different lengths can be used for blanks of different sizes without changing the machine, such adjustment of the machine being necessary only when the width of the blanks is changed or varied, and even then the time necessary for adjustment of the machine from one size of blank to another being very slight, thereby enabling the user to change the size of the blanks as often as necessary, and without losing but very little time in so doing, and whereby each blank is subjected to longitudinal com* pression to crowd the sections thereof tightly together, lor toward each other, to insure tight corners for the box, as will hereinafter more fully appear.

ln the accompanying drawings,

Fig. 2 is a detail sectional view of a part of one of the guides for the cleats, and of one of the pushers for moving the materials along, showing the use of loose blocks between the ends ofl the cleats.

Fig. 3 is a similar view showing a differ;

ent method of separating the cleats, and a different form of gage for starting the new blank. l

Fig. 6 is a perspective of one ofthe spacin g blocks that may be employed when slight space is desired between the edges of the veneer.

Fig. 7 shows a blank with the spaces between the cleats staggered relative to the joints between the edges of the veneer, said jomts being formed without any space between said edges.

Fig. 8 is an enlarged perspective of a portion of ya diderent kind of blank, the ends of the cleats being rabbeted instead of step-mitered, this being a well known form of blank and one which can be made on my improved machine by using a different and well known form of spacing block, or by omitting the said blocks altogether, as will be explained.

Fig. 9 shows a spacing block of the kind suitable for use in making the blank shown in Fig. 7 j

As thus illustrated, my invention comprises a frame or body A upon which the various operative parts are supported in suitably elevated positions. The Staplers B are disposed in a row across the machine, and are operated by a suitably actuated cross head b, in the usual and well known manner. The binding wires C are fed below the Staplers from spools or reels 'c in a manner which will be readily understood. The guides D and D extend longitudinally of the machine, below the two outside sta 1ers; and are adapted to receive the cleats lil and hold the latter in two parallel and longitudinally advancing rows. These guides are" in the nature of channel irons, and the guide D is laterally adjustable to vary the width'of the blanks. The machine is provided at opposite ends with transverse shafts F and G having sprockets for the chains H and H which run parallel and longitudinally of the machine. The upper portion of the chain H runs inside of the guide D and'the chain H outside of the guide D', being in substan-l tially the same horizontal plane as said guides. Said chains are connected by transupward when the pushers pass under.

verse bars l, which are called pushers, and which are provided with blocks z' and c" that travel in the guides D and D to push the cleats and veneer along. The block z" is adjustable on the bottom or inner side of the pusher in each case, so that it can be adjusted with the guide D for diiferent widths of blank. The machine is long enoughto accommodate a blank which is just starting under the Staplers, and another which is fully laid and waiting for the next-pusher. Out at the end of the machine where the cleats and veneer are laid in place, the guides D and D are provided with fixed stops or gage pieces J, as shown in Fig. 2, which are of a height to let the pusher blocks z' and i pass when the latter engage the rear end of the blank. The spacing blocks K are shown with this arrangement, which blocks are loose and slide along the guides with the cleats between the ends of which they are interposed. These blocks are step-mitered where they engage the cleats, are each provided with an upper projection lc that serves to separate the edges of the veneer in such manner that the end of one cleat is a distance back .from the edge of the veneer, while the other cleat extends to the edge of the veneer (see Figs. 2 and 7). In Fig. 3 the stops or gage pieces L for the guides are pivoted at Z and made high enough to engage the edge of the veneer, so that all four sheets of ve' neer can be laid and crowded up close to-` gether without space between. In such case the blocks M are used between the cleats, and the gage L in each guide is depressed by the pushers to enable the latter to pass and enage the rear end of the newly laid blank.

he gage L is then raised to normal position by the springl, or by any suitable means. Suitable clamps or guides N are provided and arranged to bear upon the blanks while they are traveling under the Staplers. These clamps which keep the work from becoming displaced can obviously be made yielding to permit the pushers to pass below. Or the pushers can be disposed in the same plane as the veneer, so that their tops are flush with the upper surface of the blanks, in which case the clamps N do not need to ield f the guides engage the edges-of the veneer, then the pushers move along the lguides a little' above the blanks; but if not, or if only one guide engages the edges of the veneer, then the pushers, or at least oneend thereof, will travel in the same plane as the veneer. The clamps N cam-therefore, be disposed to engage the tops of the blanks at any suitable points.

A Ilatchet feed'mechanism O is provided at one end of the machine for giving the shaft G, and chains H and H', an intermittent feeding movement to carry the blanaks under the Staplers. This feed mechanism is operated in any suitable manner. ln addition there is a friction clutch P controlled by a lever p for accelerating the motion of the chains, causing the latter to move forward with a quick continuous motion when it is necessary to make the new blank move faster to catch up with the blank which has just been stapled.

In operation it will be understood that the laying of the first blank is started by placing a pair of cleats against the gage pieces J or L, as the case may be. As shown in Fig. 2, a block K is then placed against the end of each cleat, with the projection lc away therefrom. Then a sheet of veneer is laid on l said cleats, and another pair of cleats placed eration is repeated until four sections are in place, care beine taken to see that the blocks are all positioned alike, so that the formation at each joint will be the same as the others. When the pushers engage the rear end of the blank, the whole moves forward to the Staplers. While this blank is being stapled, another is being laid behind it, and by the time the first blank is finished another pusher Z is ready to engage the new blank. It is at this time that the lever p can be used to effect a quick movement forward of the new blank, so that too much space or too long an interval will not occur between the blanks. Tf the guides have Gage pieces L, (see Fig. 3), and if the blocks are used, then the veneer is all crowded up together without space between, and a blank of the kind shown in Fig. 7 is made., The spaces between the ends of the cleats are staggered relatively to the joints between the edges of the veneer, and this formation is uniform. A blank of this kind can only be folded one ing the blanks.

The machine thus constructed can also be used without spacing blocks, by first tacking or preliminarily fastening the veneer to the cleats. This can be done in any suit-able manner, and the separate box sections of cleats and veneer thus preliminarily fastened together can yhen be placed in the machine and secured together by the wires C, to make a blank like that shown in Fig. 7. ln such case the edges of the veneer meet and one sheet or sect1on pushes the other.

lf desired, the form of cleats shown in Fig. 8 can be used, and blanks made by any of the methods described above. Thus the machine will, without any changes therein, Work with cleats of different lengths, adjustments only being necessary when the width of the blanks is changed. This can be done quickly, and practically no time is lost in changing from one size of blank to another.

lt is obvious, of course, that miter blocks of the ordinary character can be used, with the means for spacing the veneer disposed way, and no mistakes will be made in foldllO centrally thereof. It will also be understood that the machine is So controlled by the attendant or operator that suiiicient space is left between the blanks, as fast as they are made, to provide the wires, after the blanks are cut apart, with end portions which are long enough to be twisted together to close the box. In this connection it will be seen that the Staplers are controlled by the usual friction clutch, which latter is in turn controlled by a hand lever Q, in the well known manner. Thus the mechanism for moving the blanks along the guides can be controlled at will and the operation of the Staplers can also be controlled at will. It will also be understood, of course, that when the veneer is preliminarily tackedY to the cleats, by using tacks or brads, the gage pieces J or L, are then not necessary. In Such case the sheets of veneer with the cleats secured thereto are Simply laid in place in the guides, and 'they are easily assembled together Without using the said gage pieces. The latter can, however, be used, if such is desired.

Always, of course, the ends of the' cleats are separated or spaced apart. rIhe means for doing this may be either the spacing blocks or the tacks or brads heretofore mentioned, and in either case the blank iS given a longitudinal compression. The friction of the cleats in the guides creates an opposition to the propelling force of the pushers, `and this retardation is augmented by the back pull of the binding wires. By my improved machine and method, the result is that each blank is subjected to longitudinal compression, and is secured together while thus under compression. This means that the Sections of each blank will be crowded toward each other, and if no Spacing blocks are used the edges of the veneer will be squeezed and compressed tightly together. In any event, and regardless of whether the spacing blocks are used or not, the sections of the blank will be drawn or crowded toward each other, insuring the proper and uniform length for the blanks, and tight corners for the boxes.

The blank is contracted somewhat regardless of whether the spacing blocks are used or not. By this is meant that the general tendency is to contract the blank longitudinally, as a result of the opposing forces applied at opposite ends thereof; the pusherV resisting the back pull of the wires on all sections of the blank, and also on the blocks when vthe latter are employed. Both kinds of blocks can be employed on the machine, either at the same or different times. And, in any event, the immediate result of the stapling operation iS a fiexible blank.
