BOX-STAYING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 555,813, dated March 3, 1896.

Application filed January 13,1896- Serial No. 575,255. (No model.)

To all whom it may concern:

Be it known that we, HORACE INMAN and HARRY A. INMAN, citizens of the United States, residing at Amsterdam, county of Montgomcry, State of New York, have invented certain new and useful Improvements in BoX-Stayin g Machines, of which the following is a specifi' cation, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to the construction of machines for applying adhesive strips of paper, cloth, or other similar material to the corners of paste-board or other like boxes for the purpose of strengthening them. In the machine which embodies our present invention we prefer to effect the adhesion of the previously-gummed stay-strip to the box by means of wheels or rollers, which are carried by reciprocating heads or plungers and which will act upon the strips and the box While the latter is held upon a fixed support, sub stantially as shown and described in another application for Letters Patent of the United States filed concurrently herewith, Serial No. 575,253. The machine shown in that application is capable of a variety of uses; but in the present case we have arranged the parts and devised novel features with especial reference to the application of stay-strips to the corners of boxes, and with a view to the application of such stay-strips to two corners of the box at the same time, the preferred form of the machine being capable of adjustment for boxes of different sizes. In order to accomplish the general object which is here alluded to, the present machine differs in many features and details of construction from the machine shown in said application, all of which will be fully described and explained hereinafter with reference to the accompanying drawings, in which is illustrated a convenient and practical embodiment of our present invention.

In the drawings, Figure 1 is a front elevation of a machine to which the present improvements are applied. Fig. 2 is a section on the plane indicated by the line 2 2 of Fig. 1, the supporting-standard being broken ofi to save space. Fig. 3 is a plan viewof the parts shown in Fig. 2, the reel for the continuous stay-strip being partly broken away that parts below the same may be shown more clearly. Fig. 4 is a front View of one of the wheels or rollers mounted in its carrier. Fig. 5 is a section on the plane indicated by the line 5 5 of Fig. 4, a portion of the carrier being also shown. Figs. 6, 7, and 8 are detailed views in section, in front elevation, and in side elevation, respectively, of one of the wheels or rollers, showing the manner of securing the cutter thereto. Fig. 9 is an end view of the strip-feeding devices, looking from the right in Fig. 10, some of the adjacent parts of the machine being indicated by dotted lines. Fig. 10 is a front view of the parts shown in Fig. 9. Fig. 11 is a section upon the plane indicated by the line 11 11 of Fig. 10, looking toward the right. Fig. 12 is a detailed view in perspective of the adjustable knife or cutter bar of the strip-feeding devices, and Fig. 13 is a view in perspective of a portion of a box or cover with stay-strips applied to the corners thereof.

The working parts of the machine are represented in Fig. 1 as supported upon two pillars or standards A A, upon which are socured a common front plate A and a common bed-plate O, the several parts of the mechanism being secured to or supported by said front plate and said bed-plate. The box to be operated upon is supported in a fixed position during the application of the staystrips, and for this purpose the machine might be provided with a single supporting-arm of a proper size to receiw e the box and to support it with its upper side in a plane substantially parallel with the bed-plate C, substantially as shown in our said application for Letters Patent; but as it is desirable to enable this machine to be adjusted readily and quickly for operation upon boxes of different sizes We prefer to make the support for the box in two parts, as B and B, each of which is carried by independent slides B and B respectively, the latter being mounted upon 9 horizontal rods B which are carried by the front plate A. A right-and-left screw-shaft B is also supported by the front plate A to engage the slides B and B and is provided with a suitable hand-wheel B, so that the necessary adjustment of the parts can be effected. Each slide 13 and B also carries a complete set of strip feeding, cutting and pressing devices, so that said parts are adjusted with the parts of the box-support as may be necessary, according to the size of the box operated upon. As the strip feeding, cutting and applying devices of the two sets are identical, except for difference in position, a description of one set will suffice for both.

In suitable blocks or bearings Z) l), which are secured to the top of the respective slides B B is mounted a horizontal reciprocating plunger D, which constitutes the carrier for the wheel or rollerE. The latter is mounted to rotate upon a spindle e, which is carried by a yoke F and is free to move vertically to a limited extent in slots f) represented in dotted lines in Fig. 5) in the cheek-plates of a frame E, which is secured to the end of the plunger D. The frame F has fixed in its top a screw threaded stud D, which passes through an aperture in the yoke F and receives above the same a compression-spring d and an adjustable nut d, by which means the downward pressure of the yoke F and the wheel E may be regulated as desired. The plunger has connected thereto a link G which engages a long crank G and. is free to move upon said long crank with the adjustment of the slides 15 or 13 as the case may be. The crank G2 is formed on a shaft G, which is supported in suitable bearings on the bed-plate C, and is arranged to be connected to or disconnected from the drivingwheel G by a suitable starting and stopping device, (indicated as G,) which is under the control of the operator.

The reel II, from which the continuous strip of cloth or paper or other material, preferably already gummed, is supplied, is mounted to revolve freely on a spindle 7L, which is fixed to a standard it carried by the slide 13 or B". From the reel II the strip passes to the moistening and feeding devices, which are represented in Figs. 9, l0 and ll. These devices are supported by a plate I, which is secured to the slide 13 or B and comprise a watertank I, which is provided with a verticallyadjustable gate 1 by means of which the supply of water through. the wicking t' to the moistening and feeding roll K is regulated. The latter is mounted to rotate in suitable bearings in cheek-pieces K,which are secured to the plate I, and has formed at one end thereof ratchet-teeth 7a, which are adapted to be engaged by a pawl Z carried by a loose pinion L on the end of the shaft or roll K. The said pinion is engaged by a rack-bar L, which moves in suitable guides and is carried by an arm L pivoted on a suitable standard L on the slide 13 or 13". The arm L is provided with a roller Z to rest upon a cam D which is carried with the plunger D. In the. forward movement of the plunger D the cam D lifts the arm L and with it the rack-bar L, thereby imparting the requisite forward movement to the pinion L and the shaft or roll K, and as the cam passes from beneath the arm at the end of the rearward movement of the plunger D a spring L' restores the rackbar and pinion to their former positions, the pawl l passing idly over the ratchet-teeth during this movement of the pinion. A pressroll J is also mounted to rotate in the cheekpieces K to co-operate with the feed-roll K in feeding the stay-strip forward. A se1nicircular knife J is supported below the moistoning and feeding roll K by having its ends entered in correspondingly-shaped grooves 7t, which are formed in the eheek-pieces K, and the forward edge j of said knife J is adapted to act as a stationary cutter in co-operation with the wheel E, as hereinafter explained. The knife J may be clamped and securely held in adjusted position by tightening the nut upon the tie-bolt 7& which connects the two cheek-pieces K. A suitable guide I may be fixed upon the tank I to direct the staystrip properly from the reel II to the feed and press rolls J K.

By making the knife J curved the cuttingedge can be brought in close proximity to the feed-rollers, so that the portion of the strip between the rollers and knife is short and needs no guides or clamping devices to hold it while being cut.

The wheel or roller E is arranged to sever the stay-strip as it advances, and for this purpose it is provided with a cutting-edge to co-operate with the stationary cutting-edge j of the knife J. e prefer to form the cutting-edge for the wheel E on an independent disk E, which is secured to the body of the wheel E by screws 6.

It will be understood that both plungers D D are connected by the links G to the common crank G so that the two plungers are reeiprocated together, while at the same time adjustment of the plungers laterally toward and from each other is permitted by reason of the freedom of the links to be moved longitudinally upon the crank G In the use of our improved machine the two parts B and B of the support for the box are first adjusted toward or from each other, according to the size of the box, so that the two upper corners of the box shall be firmly supported. Thereafter the parts having been brought to rest previously with the plungers D D in their extreme rearward positions, the engagement of the eontinuouslyrotating wheel G with the shaft G is effected, and the plungers D D ii'ninediatelybegin to move forward. In the beginning of their movement the cams D I) engage the arm L L and through the described connection effect the forward movement of the roll K to feed the stay-strips forward over the corners of the box upon the supportsB B. After the movement of the stay-strips ceases the wheels or rollers E E sever the projecting portion of the strips and lay the severed portions upon the corners of the box and roll over them. In the return movement of the plungers the wheels or rollers again pass over the severed portions of the stay-strips and perfect their union with the box.

It will be evident that the leading features of our present invention maybe embodied in many different forms of mechanisms, and we therefore desire it to be understood that we do not intend to limit our invention to the precise construction and arrangement of parts shown and described'herein.
