BOX-COVERING Specification of Letters Patent.
Patented Feb. 1915.
Application filed November 9. 1914. Serial No. 871,126.
To of! whom it may concern:
Be it known that we, HAnuIsoN S. Girn and GEORGE W. HENRY, citizens of the United States, residing at Palmyra county of Lebanon. and State of Pennsylvania, and berry Church, county of Dauphin, and State of Pennsylvania, have invented certain new and useful Improvements in BOX- llovering Machines, of which the following is a specification.
Our invention relates to improvements in box covering machines, an object of the invention being to apply adhesive coated paper sheets to the bottom of the box, and also to the top of the box, such machines being commonly known in the trade as topping machines.
A further object is to provide improved means for feeding a strip of paper coated with adhesive, and applying the same to the boxes or covers, such strip automatically severed into sheets of proper length and pressed tightly upon the box or cover.
A further object is to provide improved means for supporting the strip of paper in position to be pressed downwardly upon the box or cover, such means comprising a plurality of needles movable through. oil satiiu-ated waste to keep the needles free from adhesive which would otherwise accumulate thereupon, and interfere with the operation of the machine.
A. further object is to provide an improved construction of adjustable support for a box or cover mounted upon an improved carriage with an improved mechanism for imparting reciprocating motion to the carriage, andpermitting a certain fienibility of operation to permit the perfect operation of the machine.
A further object is to provide improved mechanism for controlling the application of adhesive to the paper strip, and 'maintaining a sufficient slack in the paper from its supply roll to "the "adhesive roll to permit an easy operation of the machine in moving the paper.
s pfurther object is to provide improved mea Q. forpositio'ning a strip bf paper so that it will be secured between its ends to the bottomof the her under the paper sheet covering the bottom of the box.
A further object is to provide improved means for supplying the tape, holding the same in proper position, and automatically severing it into proper lengths as it is supplied to the boxes on the carriage.
A further object is to so construct our improved machine as to permit the same to be adjusted to accommodate various sizes of boxes and covers. r
.A further object is to provide a machine of the character stated which will rapidly and uniformly perform its functions and result in a saving of time and labor and consequently reduce the cost of manufacture.
Yl ltl'l these and other objects in View, the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in. the claims.

1 represents a supporting frame in which a transversely positioned drive shaft 2 is mounted, and to which latter power is transmitted from any suitable source, a pulley 3 being illustrated as fixed to the drive shaft and adapted to be operated by a belt (not shown).
A, clutch 4 is provided on drive shaft 2, and serves to lock a sprocket wheel 5 to the shaft. This sprocket wheel 5 is connected by a chain 6 with a sprocket wheel 7 on a countershaft 8 also supported in the frame 1.
The shaft 8 is provided with a pinion 9 meshing with a relatively large gear wheel 10 on a shaft 11 located in a lower plane than shaft 9 and serving to operate the several features of the machine as will be hereinafter explained.
The clutch 4 is normally held in released position by means of a spring 12 to which the shorter end of a lever 13 is connected. This lever 13 is pivotally connected to the frame 1 as shown at 14, andat its longer end is connected by a rod 15 with a lever 16, the latter pivotally supported between its ends on the frame 1 as shown at 17.
The lever 16 is connected by a rod 18 with a foot treadle 19, so that the operator can stand at one end of the machine, and by means of the treadle 19, throw the clutch into operation and start the machine and as long as pressure is applied to the treadle, the machine will operate and as soon as released, spring 12 will automatically throw the clutch out and stop the machine.
The end of the machine, where the treadle 19 is located, we will term the forward end of the machine, and the opposite end, the rear end for convenience of description.
At the forward end of the machine, the frame is provided with parallel guide flanges 20 to receive the grooved ends of a sliding carriage 21. This carriage 21 is made with a post 22 supporting a .form 23. This form 23 is of the proper size to receive the box or the cover, and it is to be understood that various sizes of forms will be supplied for the machine so that the various sizes of boxes may be accommodated.
. The form 23 has a pivotal connection 24 with the upper end of the post 22, and is an- 1. An arm 32 is pivotally connected to the shaft 31, and is connected by a link 33 with the free end of arm 28, so that the cam 27 compels the movement of the pivotal arm 32.
A link 34 connects the arm 32 with a lever This lever 35 is pivotally supported between its ends on a stud 36 projecting laterally from the rocker arm 30 at a point re moved from the free end of the latter, and said link 34 is of general compound curvature, so that its ends constitute journals in the arm 32 and lever 35 respectively, and allow these parts to move relative to each other as will be hereinafter explained.
A cam 37 is located on the stud 36 and in the path of movement of the arm 32 limiting the movement of the latter in a rearward direction or to the right in Fig. 4. A set screw 38in the cam 37 permits the latter to be adjusted on the stud 36, and thereby vary the stroke of the arm 32.
The upper or free end of the rocker arm 30 is connected by a rod 39 with a depending lug 40 on carriage 21, so that the movement of the rocker arm compels the reciprocation of the carriage. A. screw-threaded rod 41 is supported to turn in a bracket 42 on the bottom of carriage 21, and has a crank handle 43 in convenient reach of the operator to permit this rod to be readily turned as desired.
The screw-threaded portion of the rod 41 is positioned in a threaded opening in a lug 44 on a yoke 45. The yoke 45 has alined openings to receive the rod 39 and permit the latter to slide freely therethrough except as controlled by an adjusting sleeve 46 on the rod 39.
The sleeve 46 slides freely on the rod 39 except as limited in its movement by the yoke 45, and is connected by a rod 47 with the upper end of lever 35.
48 represents a cam stop on the frame 1 in position to be engaged by the upper end of the lever 35 in one extreme position of the latter, and this cam is adjustably secured by a set-nut 49, so that its position can be varied to control the stroke.
The particular carriage reciprocating mechanism above described is designed to insure a uniform movement of the carriage other words, the stopping point of the inward movement of the carriage must be precisely the same at all times, so'that the paper applied to the box or cover will beforce thereupon in a uniform position.
The operation of this particular mechanism is as follows: The cam 27 forces rod 33 to the right of Fig. 45, causing the pivoted arm 32 to move against the cam At such time, the rocker arm 30 begins to move to the right of Fig. et, and through the medium of the rod 39g 1noves the carriage 21 inwardly or to the right in Fig. As soon as the proper position for the carriage is reached, which is the uniform stopping position above referred to, theupper end of lever will engage cam 48, and any further movement of the rod 33 and arm 32 to the right of Fig. i will result: only in turningthe lever 35 on its pivot, which will, through the medium of the rod -47, cause the sleeve 16 to slide on rod 39, hence by adjusting the cam 48, an absolute accurate stopping position can be insured. Whenthe cam 11 compels the parts to move in the opposite direction, rod 33 willswing arm 32 to the left of Fig. st, moving the lever 35 on its pivot until sleeve 46 engages yoke 45. As the lever can then move no further in this direction, the rocker itrm will be caused to move to the left of Fig. 4, and move the carriage 21 to its extreme position toward the forw'ardenc l of the frame 1. i a 50 represents a supply roll, from which a continuous-strip '51 is'd'rawn over a roller 52 applying adhesive to the under face'of the strip 51. The 1 roller 52 is mounted in a reservoir 53 containing adhesive in liquid form, which adhesive may be glue or mueilag'e, and is maintained in a liquid state heat or otherwise. 7 7
The strip 5.1 before reaching the roller 52, is passed over a guide 54, and afterleaving the roller 52, moves through a scraper 55'. This scraper is shown clearly in Fig. 10, where it will be notedthat the same consists of a shaft 56 having a wire 57se'cured thereto at the ends of the' latter, but throughoutthe greater portion of its length located parallel with and spaced from the shaft.
The shaft 56 is supported in bearings 58 on the reservoir 53, and at one end is pro vided with a crank arm 59 carrying an integral yoke 60. The yoke 60 has screw; threaded openings for the reception of the threaded endof a rod 61 and said rod 61 is mounted to turn in a bearing 62 in the upper forward portion of frame 1.
A crank handle 63 is provided on the end of rod 61, so that the rod 61 may be readily turned to adjust the position of the scraper, and exert the desired amount of friction against the'surf'ace to remove any surplusage of adhesive. and compel. it to fall back intothe' res ervoir. V
It will be noted that by turning the shaft 56, the frictional engagement of the Scraper will be varied. The strip of paper 51 is guided by means of'a frame 6 l'rigidly' secured to the frame 1, and located above the latter and also by a roller carrying frame 65 secured to atransverse shaft 66 in the forward portion 'of' frame 1. The paper also projects over a transverse box 67, and normally at its free end rests-upon needles 68 wvhioh project through the box 67 and beyond the same as shown clearly in Fig. 6.
The box 67 is provided at its ends with arms 69, the latter having openings 70 therein to receive bolts 71 depending from the supporting frame 1. The bolts 71' are relatively long, and are provided below the arms 69 with. coiled springs '72 whichnon mally hold the box in an elevated position but permit the latter to be forced downwardly as willbe hereinafter pointed out The roller carrying frame 65*above referred to' consists: of two'forwardly projecting members"73, and 7% respectively secured to the shaft 66 at their rear ends, and at their forward ends carrying a pressure roller 75 located normally in a plane above the forward ends of the needles 68. This roller 75 is preferably made in sections as indicated, and at its ends is supported in plates 76, the latter having a plurality of openings 77 therein in any of which the trunnions at the ends of the roller may be positioned so as to adjust the roller to suit conditions. I
The paper is held'upon the top of the box 67 by meanS of bails T8 pivotally connected at their ends to the" members 73 and 74C of the roller carrying frame 65, and these bails give sufficient weight and pressure to hold the paper smooth at all times, and guide blocks 79 are positioned on a transverse rod 80 in framel, and serve to holdthe paper against lateral movement, said blocks being adjustable on the rod to accommodate different-widths of paper. I
To operate the roller carrying frame, a-
cam 81 is securedto shaft 11, and is engaged by a roller 82 on the lower end of anarm '83. This arm 83 has fixed relation to the member 73 of the roller frame 65 and may constitute an integral part of the same de sired. 1 I
A coiled spring Set connects the arm 83 with the frame 1, andexerts a rearward pull on the arm, so that when the cam turns to a position to permit it,=the spring 84 draws the "arm 83 rearwardly and forces the roller 75 downwardly.
The needles 68 above referred to are po- 1 sitioned horizontally, and slide through the box 67, the latter being filled with oil saturated waste 85-, so that the needles are kept constantly oiled and an" accumulation of mucilage upon the same is prevented.
The rear ends of all of the needles 78 are secured to a cross bar 86, in which the needles are removably held by screws 87, so that they may be removed and replaced if desired. A rearwardly projecting rod 88 is secured to the bar 86, and at its bifurcated rear end is connected to a crank arm 89 on a shaft 90 supported in frame 1.
A short crank arm 91 on shaft 90 is connected by a coiledspring 92 with the stationary frame 64, and tends always to draw the needles in a rearward direction. To limit the turning movement of the shaft 90 by the spring 92, a crank arm 204 is secured to the shaft 90 and is provided with a pin 205 which engages the frame 1, so that the spring is prevented from drawing the needles entirely out of the box. This movement of the needles by the spring is prevented by a member 93 which is pivotally supported midway between its ends on an arm 94 extending rearwardly from the member 73 of the roller frame 65.v Thismember 93 at one end, is provided with a laterally ofi set portion 95 having a set screw 96 therein bearing directly upon the arm 94.
The rear end of the member 93 is connected by a rod 98 with the crank arm 91, and the action of spring 92 exerts an upward pressure on the rod 98, such movement being limited by the screw 96 against arm 94. As soon as the cam 81 permits the arm 83 to move rearwardly, and hencepermits the spring 84 to draw the roller frame downwardly, the arm 94 is caused to swing in an upward direction. This upward movement of the arm 94 allows the spring 92 to turn shaft 90 in a direction to draw the needles rearwardly from a position under the-paper. It will therefore be noted that as the roller begins to descend, the needles begin to move rearwardly out of the way, so thatthe roller is free to press the paper downwardly upon the box. or cover as the case 'may. be which is supported on the form 23. At such time the carriage will be at its extreme inward position, and the roller will press the paper tightly upon the box or cover and hold it in such position as the carriage begins its outward movement. At such time, a pres sure pad 99 moves downwardly, and rests upon the paper exerting sufficient pressure thereon as the carriage is moved outwardly or forwardly to insure a proper adhesion; The pressure pad 99 is secured to a vertical bar 100 depending from a U-shaped frame 101. This frame 101 is fixed to a shaft 102, the latter supported to turn in frame 1, and provided on one end with a crank arm 108.
The arm 103 is connected by a link 104 with the shorter member 105 of a bellcrank-lever 106. The longer member 107 of said bell-crank-lever'is in the path of movement. of "a cam 108, the latter secured to shaft 11, and made 'in two sections as shown clearly in Fig. 2. These sections of thecam are adjustable relative to each other by means of a set screw 109, so as to regulate the length of the cam surface, and it will be understood that when said cam surface is in engagement with the bell-cranklever 106, the pressure pad 99 will be maintained in an elevated position and at other times the pressure pad will fall and exert pressure on the box.
To cut the strip of paper 51 into sheets of properlength, we provide a cutting blade 110 secured to a transverse bar 111 fixed to frame 1.. This cutter is located sufiiciently high to be out of the way of the paper and to press the paper against the same, a swinging frame 112 is provided. This frame 112 is secured to a transverse shaft 113, the latter has a crank arm 114 at one end. The crank arm 114 is connected by a link 115 with a crank arm 116 on the transverse shaft 29.
A crank arm 117 fixed to shaft 29 is engaged at its free end by a cam 118 on shaft 11, so that the cam normally holds the frame 112 in its vertical inoperative position. A
coiled spring 119 connects the free end of the arm 116 with frame 1, and when permitted by the cam 118 causes the frame 112 to swing upwardly, pressing the paper against the cutting blade 110 and severing the same in the proper length, and at the proper time.
A crank arm 120 fixed to crank arm 117 is secured by a bolt 121 and a nut 122 with the rear end of rod 123. The forward end,
momentarily stop the carriage on its rear-.
ward movement while the paper is being cut, so that there will be no drag on the cutter. This stopping of the carriage is but momentary as the stop is moved down wardly by the crank arm 120 as soon as shaft 29 is turned by the action of the cam 118 and spring 119 above described, and there is sufiicient flexibility in the reciprocating movement of the carriage to prevent any damage by reason of this stop.
In the manufacture of'many styles of boxes. particularly those designed for containing hosiery and the like, it is desirable to secure a tape 129 across the bottom of the box 130, and under the sheet 131 of paper pasted on the bottom of the box as above described.
In Fig. 19 we illustrate a box in its com pleted form showing the box in an inverted position with the cover 132 underneath-and it is to be understood that our improved machine is designed to place asimilar sheet 131 onthe cover as well as on thebottom of the boX. The tape 129 is fedfrom a spool 133 supported on a journal 134 on frame 1, and is drawn through an eye 135 on a weight guiding frame 136 located: at one side of frame 1 as shown clearly in Fig. 1.
The tape 129 is fedacross the machine by means of a shuttle 137, the latter guided inits movement. by means of parallel rods 138 which are. fixed to and supported in a transverse frame 139. The shuttle 137 is in the formofa block with-parallel openings 140 to L'QCBlVt-Bitllfi rods 13S, and at one end is formed with a chamber 1 11. i
The detail coi'istruction of the shuttle and its cooperatingpartsiis shown invFigs. 13 to 16 inclusive. The shuttle 137 is provided with an opening 11-2 communicating at one side with chamber 111, and in line with a hollowconical guide: needle 113.
A tape 129 extends through the opening 1-t2-tl1rough chamber 111, and through the needle 113, and is held against retrograde movement by a dog 114 held. in operative position by a spring 115. A tape holder 1% is provided .withopenings 1-17 to receive the rods lZ-ldand is elastically held. in a stationary position byancans. ofa "rod 118' which is secured to the transverse frame 139. I
The holder 11-13 is provided with a perforated lug 119 to receive the rod 118, and a screw 150 inthe lug 1-1-9 exerts sufficient pressureon the. rod 1-18 to..prevent undue lateral movement of the holder. A coiled spring 151 connects theholder 116 with the free end of rod 118, and actsas acushion to prevent injury in the event the shuttle strikes the holder with a considerable force.
The holder 146 is provided with a-chamber line with a nozzle 15.1.
having an opening 153 in one side in The needle 1 13 of shuttle 137 moves through the opening 153 and the nozzle 151, and deposits the tape 129 in the holder. 7 1
A dog155 in the opening 152$, exerts downward pressure on the tape, and holds the latter against movementwhen theshuttle is withdrawn; This dog 155 is secured upon a shaft 156. and is provided with a spring 157 which exertssullicient downwardpressure onthe" dog to compel it to do its ordinary functions. U i
The shaft 156 extends rearwardly from the holder 1-16, and is supported at its rear end in a bearing 158. A. crank arm 159 is secured to shaft 156 and is connected by a link 160 with a crank arm 1,61; The crank arm 161i; fixed to a shaft lGEZavhichextends through frame 1, and is provided at one side of the frame 1 with a; crank arm.163 having a roller 161 at its free end in positionvto be engaged by a lever 165,.the latter pivotally supported between its ends onthe frame 1 as shown at166, and at its lower free end having a roller 167 held against a cam 168 on shaft 11 by a coiled spring 169. The shuttle 137 is secured at its upper end to.a cable 170. One end of this cable is passed over a pulley 171 suspended from ahook 172- at the upper end of vertical weight guiding frame 136, and is secured to a weight173 which'is guided in its vertical movement by parallel rods171 carried by frame 136, and positioned in openings 175 incthe weight. The other end of-the cable 170 passes around a pulley 176supported by a laterally extending arm 177' on frame 1, and is securedv to a relatively long crank arm 178 on a transverse shaft 179 supported by frame l. 1
A crank arm 180 on shaft 17 9 isconnec'ted-by a link- 181 with: crank pin 182 on the face ofcam 168, so that the crank arm 180 is given a continuous oscillating movement to impart an'oscillating movement to arm 178, and to reciprocate the shuttle 137 transversely of the machine.
1 The transverse frame-139 is supported by a pair of crank arms 183. These crank arms 183 are secured to a transverse shaft 185, and one of the arms 183 extends rearwardly beyond the shaft and is provided with a depending link 186 having a bifurcated lower end 187 straddling a pin 188 on a'crank arm 189 fixed to shaft 179. A coiled spring 97 connects the rear end of arm 183 with frame 1 and normally holds the frame 139 in an elevated position. in 7 By reason of the construction last de scribed, the frame 139is caused to move downwardly and deposit the tape 129 across the box 180 on the form 23,. When the tape is in. this lowered position, the shuttle 13.7 is drawn to the extremeright of Fig. 17 as shown in dotted lines, and;the shears 1.90 are causedto-act to sever the tape as will now be described; v
The shears190 consist of a stationary blade 191, and a pivoted blade 192. The stationary blade. 191 is secured to a rod 193 mounted to slide in a guide frame'l9el, its movement being limited by a head 195 on the inner end of the rod. The pivoted blade 192 is provided with a crank arm 196 which is connected by a link 197 with the block 198, and the block 198 is connected by a rod 199 with the lever. 165. Hence, when the upper end of the lever 165 is moved forwardly, it will. first move the rod 198 to position the shears for cutting, and a continued movement of the lever after the rod 193 is stopped-by the head 195, will= cause the pivoted'blade 192 to move downwardly and sever the tape. I
On theends of'the carriage 21,1.ipwardly projecting perforated lugs 200 are provided,
slack creating frame 207 is provided.
203 engage over the tape as it is positioned on the box, and serve to position the tape at right angles to the longitudinal axis of the box so as to to insure .a uniformity in the proper positioning of the tape as it is de posited on the box.
It is to beunderstood that the tape is positioned on the box in advance of the sheet 131, so that as the sheet is secured tothe bottom of the box by its adhesive, it will at the same time, secure the tape midway the ends of the latter, leaving the ends of the tape free to be tied over the cover of the box as is customary.
On the end of the shaft 8, a balance wheel 206 is preferably located to steady the running of, the machine.
To prevent an unnecessary drag of the paper as it is drawn off of the roll 50, a This frame 207 is of general U-shape with its intermediate portion 208 in position to engage the paper strip 51, and cause the same to unwind slightly from the roll. This frame 207 is provided with a crank arm 209 which is connected by a link 210 with a crank arm 211 on the shaft 31, so that at each oscillat- 111g movement of the rocker arm 30, the frame 207 is caused to kick the strip 51 and give suflicient slack in the strip of paper to overcome any unnecessary drag on the strip as it is applied to the box or cover.
The operation of our improved machine is as follows: The operator stands at the forward end of the machine, which is at the left hand'end of Figs. 1, 2, 3, 4:, and 5, and has in convenient reach, a pile of boxes or covers to receive the sheets 131 thereon. Assuming the operation to be upon the box bottoms, the operator places the box 130 upon the form 23, and then presses the treadle 19 downwardly. This movement of the treadle operates the clutch 4: to start the machine. The carriage 21 moves inwardly, and as soon as it reaches its extreme inward position, the pressure roller 75 moves downwardly to press the end of the paper upon the box. As the pressure roll begins its downward movement, the needles 68 are drawn rearwardly through the box 67 out of the way of the descending roller. After the roller has imparted the initial pressure to the paper, the pressure pad 99 descends, and presses downwardly upon the paper during the forward or outward movement of the carriage 21. During this outward'movement of the carriage, the frame 112 is oper- 'ated to sever the paper against the cutting blade 110, and as soon as the'cutting operation is completed, the needles 68 are projected forwardly and support the end of the paper strip until the roller again descends as above explained. If tape is supplied to the box, it is deposited on the box before the paper, and this positioning of the tape by the shuttle 137, its severance by the shears 190, and its movement downwardly on the box, takes place before the paper is permitted tocover the same. The several cams and cooperating mechanism so times the operation that each step of the process or function of the machine takes place at the pre-determined time, and at each complete reciprocation inwardly and outwardly of the carriage 21, a sheet of paper and the tape are caused to adhere to thebottom of the box. When a top sheet is being applied to the covers of boxes, the tape will not, of course, be used, and in many boxes the tape is not desired, so that this feature of the machine can be operated or not as desired 0 In the claims we have used the word box to signify any receptacle, either body or cover for receiving the sheet of paper thereupon, and hence in the employment of this term in the claims, we would have it understood that we are not limited thereby.
Various slight changes might be made in the general form and arrangement of parts described without departing from our. invention, and hence we do not limit ourselves to the precisedetails set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
