BOX-NAILING MACHINE.

SPECIFICATION' forming part of Letters Patent No. 553,094, dated January 14, 1896.

Application filed June ZS, 1894. Serial No. 515,456. (No model.)

To colt whom, it may concern:

Be it known that I, HERMAN W. Bncnr, a citisf-en of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Box- Nailing Machine;V and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings,with the reference letters and numerals marked t-hereon, which forma part of this specification.

This invention relates to machines for nailing boxes of all sizes for packing and shipping purposes. It is best adapted, however, for constructing boxes of smaller sizes-like cigar-boxes, for instance-the object being to assemble bysuitably-constructed machinery all the parts required, lid excepted, which make up the boxes, and nail them together after that. At the same time provision is made for adjustment to permit the nailing of boxes of different sizes.

In the following specification, and particularly point-ed out in the claims, is found afull description. of my invention, its operation, parts, and construction, the lat-ter being also illustrated in the accompanying drawings, in which- Figure l is a longitudinal vertical section of the machine, taken on line l l of Fig. 2. Fig. 2 is a vertical cross-section on line 2 L of Fig. l. Fig. 3 is a horizontal section and top view of parts above the bed-plate. Fig. 4 is a similar view showin g parts below the bedplate. Fig. 5 is an enlarged top view and horizontal section of the central part of the machine, the line of view or section being taken at different heights, which are indicated by letters a, h, and c in Fig. l, which letters are correspondingly placed in Fig. 5. Fig. 6 is an enlarged sectional detail view of the construction, whereby the nail is placed in posi tion to be driven. Figs. 7, 8, and 9 are differcnt elevations of a feed and nailing device with accessory parts, different ones being shown in each elevation in place of others which are omitted. Fig. 10 is an enlarged front view showing a part of the riail-supp1y ing device. Fig. ll is a complete rear view of the same.

four of these sides to make a box-frame without the bottom. These four sides are next nailed together. 'The completed frame is then advanced and brought in proper position to receive the bottom, which is finally nailed on and the box completed.

To this end the machine consists of devices whereby the sides are assembled, of devices whereby they are nailed together, of a device whereby the box-frame and the bottom are brought together, of devices which nail the lat ter to the former, and vof a general nail-feed device whereby the nailing devices are supplied with the nails.

The machine is adapted to construct frames only without bottoms, which latter may be put on by other means, or by hand; but this bottom-nailing portion is preferably made a part of the whole.

The sides are received by four inclined chutes 20, into which they are put in an upright position. These chutes have no complete bottoms, the box sides being only supported near their ends, which is sufficient, and whereby the width of the chute becomes adjustable and all unnecessary friction is obviated and the sides are caused to freely slide down. The lowest parts of all the chutes are at the same height which brings the lowest side in each chute to a corresponding position and to the same height with the remaining sides. They are held back in the chutes by upright guides 2l, which are so set that when the four lowest sides are lying against these guides the joint ends of the sides are in contact with each other and in a position they relatively occupyin the completed box. Between the lower end of the chutes and between them and guides 2l thereat there is a space of sufficient width to permit the lowest sidel in a chute to leave the latter and pass edgewise down on the guides into this space. Normally, however, such passage is prevented by pawls 22, which are pivotally connected to guides 2l and reach into this space mentioned. Thereby the lowest side of each inclined stack, after leaving the chute proper, passes upon these pawls and rests thereon.

23 are four standards serving as guides for IOO feed-bars 24 held to them by slides 25, whereby they become capable of a vertically-reciprocating motion. They also support guides 2l, which are connected to them by brackets, as shown. At the lower end these feed-bars carry pawls 26, which are so located thereon as to extend over the upper edge of the lowest side in each stack, whereby as a consequence they engage said sides when moving downwardly and carry them with them. Pawls 22Yreadil y yield to the positive pressure of the feed-bars and clear the space for the advancing sides, dropping back again to their normal position as soon as these latter have passedbelow them. The return of these pawls may be eifected by springs or gravitation, but preferably the latter method is used,

, as shown, for which purpose the outer part of the pawls is made sufficiently heavy to raise up the inner part and also carry the weight of the side which it temporarily supports. It is needless to say that the downward motion of all the feed-bars starts and terminates at the same time and they all stop at the same height, so that the four sides which have been pushed down together are still in the same relative position and ready for naiiin g. They are held in such position by upright guides 2l and springs 27 holding them against the former. Meanwhile the weight of the stack of sides has caused another side to slide into the place of the one just pushed down, such side now occupying the same position as the other one, lying against the guides and being held up by pawls 22. At the same time the feed-bar commences to rise again to be ready for the next operation,pawls 26 swinging readily out of the way, after which they drop again to their normal position and on pins 28, which hold them stiff during the iirst part of their movement when Jthey push the sides down. The reciprocating motion of the feed-bars is accomplished by levers 29, connected to them by links 30 and actuated by grooved cams 3l. These latter are rotated by shafts 32 33, which rotate together, being operatively connected byanother shaft 34 and bevel-gear wheels 35.

33 may preferably constitute the drivingshaft, for which purpose it carries a drivingpulley 3G. The nails are usually driven in through the ends or shorter sides and into the longer sides of the box, for which purpose the shorter sides overlap the ends of the longer sides.

The nails pass down point first through chutes 37 into hammer-ways 38, which terminate opposite the short sides and at the proper points thereat to reach the edge of the long sides, as is shown in the drawings. The speed which they attain carries them readily through the horizontal part oi' the hammerways, into which they drop, their points against the sides to be nailed. (See Fig. 6.) The rear part of the hammer-way is occupied by hammers 39, which are aiiixed to slides 40, moving in guides 4l and reeiprocated by grooved cams 3l. These grooves are in the other side and diiierently shaped from the grooves which actuate levers 29, the object of such difference being to cause the nailing to proceed at the proper time-that is, when the feed-bars have pushed the four sides io the proper position with reference to the hammer-ways and when said sides have stopped moving and the feed-bars are starting on their upward stroke. The cams new cause slides 4() to move inwardly, whereby the hammers pass clear through the hammer-ways and against thebox ends, driving the nails in 'front of them into the latter. In place of one cam with a groove in each side, two different cams. side by side, each with one groove, may be used. For higher boxes,requiring three nails. the castings containing the hammer-wa ys m a y be detachable and exchanged for such having the required number of ways. Slides 40 are high enough to admit additional hammers to be inserted. By t-he time the nails have been driven another set of four sides is being pushed down by the feed-bars, occupying the place of the set previously nailed, which latter set, now forming a trame,is thereby pushed out and disengaged from between guides 2i and springs 27. The disengaged frame drops onto a partition 42 in such a manner as to be tilted, (see Fig. 2,) and is thereby caused to drop edgewise into a receiver 43, the width of which corresponds with the thickness or height of the frame.

44 is a driver reciprocating in a manner so as to traverse the receiver through its entire length. At the time when the box-frame drops the driver has retreated, so as to permit the i former to drop in front of it and be within its path. One of the walls of the receiver, designated by 45, is very thin, preferably of sheet metal, land slotted at 46 to permit a connection between the frame-driver 44 and a supplementary driver 47, which is at the other side of wall 45 and of even height with the first driver. Against this wall 45 terminates a chute 4S, which supplies the bottoms, the lowest one of which rests always against this wall and is in front of the supplementary driver. This latter is about of even thickness with the bottoms for the boxes, and by reason 'of the sides of the chute stopping short of wall 45 by a distance which is equal to this thickness,the supplementary or bottom driver is enabled to traverse and pass the discharge end of the chute 48. The effect of this construction is that the frame and bottoni drivers, by reason of their connection reaching1 through slot 46, move together7 one on one side of wall 45 passing through recess 43, the other on the other side thereof passing across the discharge end of chute 4S; and, further. the front ends or faces of the drivers being in line, it follows that the box-frame in front of the one driver and the lowest bottom in the chute are advanced simultaneously. At the proper time the motion of the drivers stops, at which time the frame with the bottom in proper position thereon has arrived opposite IOO IIO

i l v the hammer-ways 49, which are so disposed in groups that the. nails therein when driven pass through the bottom into the edges of the sides, one nail in each group passing into each of the long sides and one into each short side. W'all 45 terminates before the first group of hammer-Waysis reached, so that by the time the box-frame and bottom are in position to be nailed they are in direct contact with each other. This contact is completed by springs 50, which press the bottom against the frame, While another spring l holds the frame down in position.

Nail-chutes 52 supply the nails, point first, the same as first explained, they dropping into the hammer-Ways in front of hammers 53, carried by slides 5L, which reciprocate in guides 55. Slides 5a are moved each by a lever 56, pivoted at 57 and carrying a roller at its other end, which occupies a groove in a cam 58. rlfhere are two of these cams and levers, one for each one of slides 54 and for each group of hammer-Ways. These cams 58 sit on shaft le and the grooves thereon are so shaped as to cause the hammers to operate, for the purpose of nailing the bottom on, at the time when frame and bottom have arrived in the proper position and when their drivers eti and at? are starting on their return stroke. The motion of these latter is obtained from a grooved cam 59 on shaft 33, which operates a lever GO, pivoted at Gl and connected to driver it by means of a series of toggle-joints (32. Driver yi7 is connected to and carried by driver Lit, as already explained.

For the purpose of adjusting the machine for boxes of different lengths, two of the four principal groups of devices, and designated by a and b in Figs. 3 and 5, are carried by a bedplate 63, Which rests on ways Gat on the machine-frame, and on which it is adj ustable by mea-ns of a screw U5, opera-ted by a handwheel 6G, connected to said bed-plate and passing through a stationary nut G7. rlhis bed-plate also carries `the bea-rings for shaft 32, so that all parts on which said devices a and b depend for operation may be moved together to or from the other devices. After adjustmentof the bedplate the particular bevel-Wheel is pushed along shaft Sat and on a key 69 thereon, and put again in Contact with the bevel-Wheel on shaft 32, in which position it is held by a set-screw. The outer one of the two bottom-nailing devices has naturally to follow this adjustment, for which purpose frame 70, which carries the corresponding' group of hammer-Ways and hamin ers, with their slide, is also adj usted on Ways 7l by means of a screw 72, stationary nut 73, and hand-Wheel 74. The bracket which forms the pivotal support 57 for lever 5G, as Well as the outer one of cams 58, have of course to follow also this adjustment, the latter being adjusted on key (i9, the same as the adjacent bevel wheel. For adjusting the Width of boxes, two of the four devices, and designated by a and c, have to be adjusted to or from the other devices, for which purpose they rest on ways and are connected to screws 76, passing through stationary nuts 7' 7 and operated by hand-Wheels 7S. The only diiference in this construction is that the Ways on which device a is adjusted are located on bed-plate G3, While the Ways for the other device are on parts of the main frame. This difference is caused by the necessity of a capacity of adjustment in ttvo directions for device a. The corresponding cams 3l on shafts and 33 are, following this adjustment, sliding on keys on these shafts. In this second adjustment for Width of boxes, the bottom-nailing devices are not affected and remain stationary, with the exception of the hammer-Ways and hammers therein, which are changed to meet the points Where the nails are to be driven in. Tall 79 of the receiver which carries the tilting partition 42 is connected to a base S0, resting on Ways Si, on which it is adjustable for lower or higher boxes, to or from Wall 45, by means of a screw 82 passing through a stationary nut S3 and operated by a hand- Wheel S-l. This Wall 79, unlike Wall 45, does not terminate in front of the ha1n1ner-Ways 49, but continues past them, so as to be enabled to support the frame While the bottom is nailed toit. The Width of the face of driver t does not need to follow the'adjustment of Wall 79 in order to fill out the Width of receiver 43, because it Will always push the frame for Ward even if not covering the end of it, and being not dependent for guidance on the Walls of the receiver, but sliding in Ways 85. The stroke of the two drivers does not require any adjustment, the same being so arranged as to bring one end of the shortest frame always to the first set of hammer-Ways, the other set of the latter, carried by frame '70, being adj usted to the length of the frame. The upper ends of the sides of chutes 2O are supported by rods 8G, on which they are capable of sliding during adjustment, the lower ends moving with standards 23. These upper ends are held in their adjustment by nuts S7. Of the chute feeding the bottoms, only'one side requires adjustment, the one Which is farther from the starting-point of the drivers.

All the nail-chutes Which supply nails to adjustable devices are provided with a pliable section SS, preferably of rubber tubing, the balance being preferably brassv tubing, which pliable sections facilitate and follow adjustments.

To avoid confusion in the drawings all the nail-chutes 3'7 and 52 are partly omitted and partly shown in dotted lines.

W'here these machines are built for one certain size of boxes the construction may be great-ly simplified, and all the parts described as adjustable may be rigidly secured in fixed positions. Vhile the time which the adjustment from one side to another requires is of no consequence, in view of the fact that these machines are intended for manufacturing boxes in large quantities, an d if adjusted once lCO IIO

IZO

to a certain size remain in such position probably for a long time, it is nevertheless preferable to limit the range of adjustment to certain sizes in one machine to avoid unnecessary complications, and provide additional machines with another range of adjustment when the variation in sizes is considerable.

The nails for the nail-chutes are thrown upon an inclined shelf 89, having at its upper part a number of troughs 90, from the lower ends of which and in line with their centers and deepest part grooves 91 start downwardly. The width of these grooves is such as to admit the shank of a nail without permitting its head to pass through, which causes all nails coming from trough and caught by grooves 91 in the desired way to be suspended therein in a nearly upright position, their points downward, in which position they slide down on shelf 89. They come to a temporary stop in the upper part of inclined grooves 02 of a cutoif which reciprocates below shelf 89 at right angles to the direction of grooves 91 and at the lower ends of the latter. The angle of these ininclined grooves in this cut-off is such that not more than one nail can enter them, the sharp points at G8 passing between this one nail and the next one above as soon as the cut-off starts upon its motion. The straight upper edge of the latter holds all other nails in grooves 91 back, while the one nail caught by each inclined groove proceeds, moving down in grooves 91, in the same ratio as the cut-ofi' continues its motion across. (See Fig. 10.) The lower ends of inclined grooves 92, as well as of grooves 91, are widened, as shown at 93 and 94, the increase being suflicient to permit the head of the nail to pass through, so that when openings 93 and 91 register, at which time the motion of the cut-oil stops, the nails lose the support which the narrow grooves 91 thus far furnished and drop through these larger openings into the upper part of the nail-chutes, the entrance to which is facilitated by a funnelshaped mouth 95. lt should be mentioned that these latter are in line with and below openings 93, so that when the nails drop openings 93 9i and mouth 95 are all in line andV below one another. For convenience sake, these funnel-shaped mouths are all contained in one rail 96, which receives and holds the upper ends of all the nailchutes 37 and 52, and also serves as a support for the lower end of inclined shelf 89. Slots 97, in line with and below grooves 91, permit the Shanks of thenails to pass into the f unnels. After the nails have been released by the cut-off they pass rapidly down through the nail-chutes and enter their respective hammer-ways in front of the hammers therein, where they lie until driven home by the latter. The cut-off returns immediately to its normal position by a motion which may be obtained from any of the moving shafts below in any suitable manner. A specific movement will be described later.

Below troughs 90 and between grooves 91 are slots 98 of considerable width, whereby the solid part of shelf 89 between these slots and to each side of grooves 91 is so diminished as to aord no resting place for nails. This causes all of the latter which have not entered grooves 91 in the proper manner to drop through these slots 98 onto another shelf 99, from which they slide into a tray 100,whieh prevents their waste and keeps them from dropping all over the machine. This tray is pivotally connected to a slide 101, moving in grooved guides 102 and reciprocated by a crank 103 on shaft 3i, to which it is connected by a yoke 101. After the cut-off has done its work this tray commences to rise until it is in line with the highest point of shelf 89 and above the upper end of troughs 90, at which time it is tipped by reason of a lever 105 on it coming in contact with a stop 100. This causes the nails therein to be thrown upon troughs 90, from whence some pass on and are retained by grooves 91, while the balance, not caught, drop back through slots 98 onto shelf 99. Until the return of tray 100 the nails are held back by slide 101, which has moved up with the tray and now lies across shelf 99.

lt is my object to have quite a quantity of nails in excess of immediate requirements in motion, so that grooves 91 always receive a sufficient quota out of the whole. To prevent any of the nails from passing down on shelf 89 when tray 100 empties itself, l provide a partition 107 reaching across the lower ends of slots 98, and parts of which I extend down into said slots. This partition holds the nails back and gives them time to drop through slots 98. On the downstroke of slide 101 a pin 108 strikes a rod 109, connected to the partition, which latter is pivotally suspended and causes it to swing away from shelf 89 and out of slots 98 therein. The object of this movement is to release any nails which might have become lodged against this partition and in slots 98. lVhen the slide rises and before the nail-tray tips, this partition assumes its normal position against the shelf` being carried back by a counterweight 11o, The reciprocating motion of the nail cut-off is obtained by a lever 111, to which it is con nected and which is actuated by a cani 112 on slide 101. The action of lever 111 is counteracted by a spring 113.

I will new proceed and reeapitulate the different functions of the machine in their proper order. The four sides of the box are taken from four chutes, all converging toward a common center and their lower ends all at even height, so that the lowest side in each chute is also at even height with the sides su pplied by the other chutes. The feed device moves all four sides at once and an even distance, so that all sides stop at the same time and again at even height. The means which guide the sides during this movement are so disposed that the sides occupy the same position to each other which they occupy in the completed box. The feed device having com- ICO IIO

pleted its work-that is, moved the sides within reach of the nailing devices-returns for the next set of sides while the latter devices drive the nails. This first result of the machine is an oblong frame without a bottom and it is discharged from its position by the next set of four sides while they advance to be nailed. The discharged frame falls onto a tilting partition in such a manner as to drop sidewise into a receiver and in front of a driver. This latter advances the box-frame, while a supplementary driver advances a bottom for it taken from a chute across the lower end of which it passes, the two-that'is, frame and bottom-advancing together and stopping at the same time, being then in a position which they occupy in the completed box. lWhen they stop they are opposite another set of nailing devices which drive the nails, while the drivers return to be in proper position to advance anot-her bottom and the next frame which is now about ready to drop. This second frame, while advancing to be nailed, pushes the completed box, previouslynailed, out. aies in conjunction with this cycle of functions and delivers the necessary set of nails cach time.
