Referringto the drawmgs:-1 designates the frame of the machine in which is journaled the main shaft 2 which has loosely mounted thereon, a pulley 3 provided with a clutch member 4 which co-acts with the member 5 that is splinecl on the shaft 2, said member 5 being brought in and out of en-.

The shaft 2 has a. pinion 1o};

spective cross-head 34, which is guided in the '16, journaled in theframe 1.

wheel 7 fast on the shaft 8. The shaft 8 has 1 against its adj acent plate 50. The free ends' I secured thereon the eccentrics 9 and 10., the

sprocket wheels 11 and 12 and a cam 13.-

The sprocket Wheel 11 imparts motion'to a sprocket chain 14 which passes partly around a sprocket wheel 15, which is fast on a shaft The shaft 16 has secured thereon a bevel gear wheel 17 which meshes with a gear wheel 18 secured to a shaft 19 that is j ournaled in the frame 1 and has secured thereon a crank disk 20 on whose wrist pin 21 is coupled one end of a link 22 whose opposite end is coupled at 23 to an arm 24, secured'to a shaft 25 which is journaled in the standards 26 and 27, and is adapted to rock said shaft, for a purpose hereinafter described. f It will be understood that power is imparted to the pulley 3. in any manner as by a elt 28.

The eccentrics 9 and 10 aree'ach provided with a connecting rod 29,,the outer end'of' which is pivoted at 30 to its respective lever 31, which are fulcrumed at 32 in the frame 1 and the upper end of each of said levers is connected, as at 33 and in any suitable manner, with a projecting member'33 of its reframe 1. Guided in the frame 1 are the plates 35, in each of which is swiveled'a'right and a' left hand threaded screw 36 which engages the plates, 37 and 38,.respeotively, so as to cause said plates to either approach or recede from each other, for a purpose herein: after described. The plates 37 and 38 have,

each pivoted thereto,-.at 3-9, a bar 40 which serves as a'clamp to retain the sides 41 of the.

. body portion 42 of a paper box, seen in Fig.

15, against the plates 37 and 38 upon which said body portion 42 is placed. The bars 40 are retained, normally, in their opened positions by springs 43, as seen in Figs. '6, 7 and 8. The-bars 40 are each provided with a I roller 45' whichris in the path of the cams 46,

it being noted that the bars 40-are, .in the presentinstance, fourin number, as illustrated in Fig. 4, and the cams 46 are two in number and that each 'of said cams acts in ,conjunction with the two rollers 45 that are adj ace'nt thereto as hereinafter described.

Risin from the cross-heads 34 are plates 47 in w ich are loosely fitted the rods 48 ,whose inner ends are firmly secured to the lates 49, which are-integralwith or may have secured thereto, the cams 46. The rods 48 are secured in any suitable manner,

' as for instance by the bolts 53, see Fig. 7, to

their res ective plates50 so that said plates,- their ro s 48, theplates 49- and the parts carried by the latter all move as one, for a purpose hereinafter described.

The rods 48 are each encircled by a sprin I 51, one end of which bears against a threaded sleeve 47 which has threaded engagement with a plate47, while its opposite end bears of the rods 43 are provided with nuts 52 'forward position so as to cause their points to project beyond their respective plates 49. The plates 49 are each provided with a ledge 56 which rests upon springs 57 and have a slot thereinthrough which passes a rod 59 which has pivoted thereto acam 60 that bears against a plate 61 so asto clamp said ledge 56 in its adjusted position, it being noted that the ledge 56-is fitted in-a slot 62, in the plate 49, to permit its adjustment relatively to the catches 54, for a purpose hereinafter described. The end of the rod 59, opposite that in which the cam 60 is pivoted, is secured to a plate 63. The springs 57 are each supported, preferably, in a socketin a block 64 provided with bolts '65 which are fitted in slots 66, see Fig. 9, in theplates '49 topermit said block 64 to be raised and lowered to conform to the adjustment of the ledge-56. a

The plates 35 are each provided with a projecting member 67 which partly fills the ,gap between the plates 37 and 38, see Figs. '6, 7, and 8,so as to provide an abutment at this point for the inturned edges 68 in the ends of the body portion 42 of a box. The

cross-heads 34 are each provided with a toothed rack 69, see Fig. 1, with which en ga es the screw threaded-portions 70 bf a rod 71, whichwhen a revolving motion is imparted thereto causes said cross-heads 34 to either approach or else recede from each other. The frame 1 ofthe machine is provided with toothed racks 72 with which engage the Worms 73, which latter are splined .on the rod 71 so as to be rotated thereby and by reason of their engagement with the racks 72 will cause the plates 35 to follow the movement imparted to" the cross-heads 34 by the rotation pf said rod 71 so that no relative movement occurs between a plate 35 j and the plate 49 adjacent thereto.

The frame 1 has secured thereto the blocks 74 which serve as stops to limit the outward movement of the plates 49. Guided in ways 75, in the frame 1, is the cross-head 76 which is provided with a roller- 77 which is in contact with the cam, 13, as best seen in Fig. 12, it being noted that said cross-head 76 has connected therewith the bar 78 which is provided with slots .79 through which are passed the bolts 80,

which are also passed through the bars 81 so as to'secure the same to the bar 78, for a purpose hereinafter described. The bars 81 have fitted thereon the bars 82 which have slots 83 therein, through which are passed thebolts 84- which retain said barsof which is hereinafter described.

82 intheir adjusted positions relatively to the size of the paper boxes to which their end portions 85 are to be affixed.

The standards 26 and 27 are each provided with guide pulleys 86, partly around which are passed their respective cords 87 to one end of each of which is secured a weight 88. The opposite end of'each of said cords 87 is secured to its respective follower 89, which bears against a stack of end portions 85, placed in said standards 26 and 27 and feeds 'said end portions 85 to the grippers or feed plate 90, which are carried by the arms 91 fast on the shaft 25, for a purpose hereinafter described. Loosely fitted on the shaft are arms 92 which co-act with their respective arms 91, as hereinafter described. The grippers 90 each consist of a head 93 which is free to turn on its axis or journal 94, see more particularly Fig. 5. The heads 93 are eachprovided with a spring 95, a stop 96 and a serrated plate 97, the object of all The arms 91 have pivoted thereon their respective arms 98 in which are the journals 94 of the heads 93. The arms 91 are each provided with a stop 99 which limits the movement of 1 its arm 98 in one direction against the action of its spring 100. The arms 91 have each loosely fitted therein a rod 102 which is encircled by a spring 101, one end ofwhich bears against its respective arm 91, while its 0 posite end bears against a nut 101* on said rod. The rod 102 has a head 144 thereon, for a purpose hereinafter described.

The standards 26 and 27 are provided with the members 103 and 104, which have -fitted therein, the blocks 105, which act as guidesfor the end portions 85, hereinbefore referred to, and which may be adjusted relatively to different sizes of boxes. The guides 105 are retained in their adjusted po'- sitions by tapjbolts 106 which are screwed into the guides 105, it bein noted that said bolts 106 pass through s ots 107,, in the - members 103 and 104, whereby said guides 105 may be moved along the members 103 and 104.

The arms 92 are each provided with a spring 108 which retains said arms in their proper positions relatively to their respective arms 91.

The standards 26 and 27 have each a rod 109 swiveled therein as at 110, in Figs. 3, 10 and 11, it being noted that said rods 109 are each provided with a left and a right hand screw thread which engage the members 103 and 104 respectively, so that the two latter mtg be adjusted relatively to each other accor ing to boxes of different sizes. The rods 109 have the hand wheels 111 secured thereon whereby said rods may be readily operated.

Thestandards 26 and 27 have each ivoted thereon at 112, the reservoirs 113 wit which are connected the pipes 114, it being noted that said pipes consist of sections pivoted together whereby they may turn on their pivotal connections, for a purpose hereinafter described. Certain of the pipes 114 discharge an adhesive material, contained in the reservoirs 113, into the hollow frames or receptacles 115 from which a portion of said material flows into the receptacles 116, for a purpose hereinafter described. The receptacles 116 are each connected by set screws 117 to their respective pipe 118, which depends from the reservoirs 113, as seen in Figs. 1 and 3, and supply adhesive material to the receptacles 116. The pipes 118 are opened and closed by their respective valve 145, and the pipes 114 are opened and closed by their respective valve 146.

The receptacles and 116 are provided with openings 119, see Fig. 14, in each of which is fitted a valve 120 whose plug 121 is normally seated on the parts 122 so as to close the same, it being noted that said plug is provided with a stem 133 a portion of which projects beyond the face of said valve, for a purpose hereinafter described, and, fur thermore, that said stem 123 isencircled by a spring 124 whose object is to retain the valve 120 normally closed. The members 125 of the frames 116, are each in contact with their respective cam 126 which is secured onthe shaft 25, as seen in Fig. 1. Thelstandards 26. and 27 are in engagement with a rod 127, swiveled in the frame 1, it being noted that said rod 127 has a right and a left hand screw thread thereon so that when it is totated it causes the standards 26 and 27 to said rod 127 is turned. I

The sprocket wheel 12, as seen in Fig.6, imparts motion to the sprocket chain 128, which is in engagement with a sprocket wheel 129 that is splined on the shaft 130 which is journaled in a standard 131 secured to the frame 1. Guided in ways 132, in the frame 1, is a plate 133 in which is a slot 134 through which passes a clamp screw 135 whose object is to retain said plate 133 in its adjusted position. Risin from the late 133 is a frame 136 in which is journale a shaft 137 which has secured thereon, the bevel gear wheel 138 which meshes with a bevel gear wheel 139 fast on the shaft 130. The shaft 137 has secured thereon, the sprocket wheels 140, in the present instance two in number and partly around which latter are passed the sprocket chains 141 which alsopass partly around the sprocket wheels 142, see also Fig. 1, journaled in the frame 136. The sprocket chains 141 are provided with hooks 143 that are adapted to take hold of a paper box, when finished, and remove it from the machine. 1

The operation is as follows The rod 71 either approach or else recede from each other, according to the direction in which is rotated, either from right to left or vice versa, so as to cause the cross-heads 34 to be brought either closer to or away from each other according to the length of the boxes to which the end portions 85 are to be aflixed.

- cross-heads 34. The rods 36 carried by the plates are' then rotated whereupon the plates 37 and 38 are caused to either move toward or away from-each other according to the direction in which said rods are rotated and thus adjust said plates-relatively to the width of the boxes to which the'end portions 85 are to be alfixed. The rods 109 which are employed for regulating the size of the box end receptacle are then rotated and cause the members 103 and 104 to be brou ht either toward or else away from eachzot er according to the length of the end portions 85 of a box, after" which the guides 105 are -moved either inwardly or outwardly according to the width of the end portions 85 of a box and are retained'in theirad-justedpositions bytheclamping screws 106. The receptacles 115, for the adhesive material, are then brought either nearer to, or away from each other by the operator so as to be properly located relatively to the members 103.

and 104, it being apparent that the pivoted sections ofpipe 114 permit of this adjustment, and that when the parts are in proper position, certain of the pivotaljoints in the pipes 114 are tightened. so as to retain the said pipes and the receptacles 115, firmly, in their adjusted position. A follower 89 is then brought into its extreme outward position and a plurality of end portions 85, for the boxes, are placed in their respective standard 26 or 27, it being understood that both standards are supplied with end portions 85. As soon as the follower 89 is released, the weight 88 connected therewith exerts a pull thereon and causes the follower to bear against the end portions85 to feed them to their respective grippers90.

Assuming that the reservoirs 113 are supplied with an adhesive material it is evident thatwhen the valves 145 and 146 are opened this material will flow through their respective pipes and fill the receptacles 115 and 1 16 with the same. A body portion42 of a box is then placed, in an inverted position, on the forms or plates 37 and 38, after which the clutch member 5 is shifted so as to cause it to interlock with the clutch member 4 whereupon the machine is put in motion. This causes the shaft 8 to rotate and impart motion to the eccentrics 9 and 10 whereupon the crossheads 34 are. caused to reciprocate which bear against'the springs 51 and these latter transmitmotidn to the plates 50 which by reason of their connection with the rods 48, impart a motion to the plates 49. When 8o the-shaft 25 is rocked and brought into a position corresponding to approximately the quarter of a revolution from the position seenin Fig. .1, the cams 126 permit the receptacles 115 and 116 to move toward the standards 26 and 27 and when the stems 123, in the valves 120 are brought in contact with an end. portion 85 they are moved inwardly and open said valves and permit some of the adhesive material in said receptacles to escape therefrom and adhere to those parts, of the end portions 85, that are brought in contact with-the inturned edges 68. The cams 126 are so shaped that the time in which the valves 120 remain open is of comparatively short duration' In the meantime the arms 91 have also made a quarter of a revolution whereupon the 'end portion 85 which was in contact with its respective gripper 90, when the arms 91 were in a vertical position, is now brought into a position in alinement with the inturned edges 68 of the body portion 42 of the box su ported upon the plates 37 and 38. When t e' arm 91 is turning in the direction indicated by the arrow in Fig. 11 it carries with it an I l'CO end portion 85, during which time the arm 92 remains stationary and does not turn until the head 144 is brought in contact therewith and-this occurs when the arms 91 and 92 are parallel witheach other, it being apparent that the end portion is now carried by both of said arms, between which it is -'located and firmly held in position after leaving the standard 27. On the return movement of the shaft 25 the cams 126 return'to the position seen in 1, whereupon the receptacles 115 and 1,16 are'swung outwardly from the end portions 85 and close the valves 120 and furthermore leave room forthe arms 91 wh 11 the latter are returning to their'vertic al positions. When the grippers have brought their respective end portions 85, of a box in the desired position relatively to the body portion 42 thereof, said grippers are carried back to their former positions with the arms 91,to which'they are secured,- itbeing understood that the serrated plates 97 release the. end portions 85 by reason of the yielding of the springs which permit said:-

plates 97 to slide on the end portions 85 on their return movement prior to bringing forward a subse uent end portion 85. The springs 100 yie d and-thus permit the plates 97 to ride over obstructions in the end portions 85 such obstructions exist. When a gripper 90 has com leted its downward stro c it .places' an en portion 85 between a catch 54 and a ledge' 56, see Fig. 7, whereupon said endportion 85 is securely retained in pov sition in a plate 49 prior to its being carried forward, as hereinbefore described. 'When the plates 49 complete their forward movements, they press the end portions 85, carried thereby, firmly against the inturned edges 68 and-cause them to adhere thereto.

The cams '46 engage the rollers 45 and cause the bars 40 to clamp the body portion 42 of a ..the bars 82 and consequently the body portion 42 of a box with itsend portions 85 secured thereto and brings it in position to be taken u and removed from the machine by the hoo s 143 on the sprocket chains 141,

see Fig. 6. 'The finished boxes slip off the hooks 143 when the latter reach the point I indicated at B in Fig. 6 and from which point they may be directed to any desired 'sot.'

' the rece tacles for the box ends It will be apparent that in the broad scope of my invention after the box su port and ave been adjuste to the proper size it is only necessary to place a box, which has been weakened or bent in the usual manner, on the box support and then start the machine. The entire operation of clamping the box to its, support, applying the paste to the box ends, feeding the box ends into their proper position with respect to the supported box, simultaneously securing the two ends to the box, raising the box above its sup ort and removing the finished box to a esired place, is entirely automatic.- The diiferent parts of the machine may be readily and quickly adjusted .acording to the size of the box and boxends which it is desired to secure together. It will be apparent that while I have described the device as adapted to secure the endsto a box, other portions of a box such as the sides or other parts may be secured thereto, if desired and still be within the scope of my invention.

In order to adjust 51 I em loy threaded sleeves or'busbings 47 which are fitted in threaded openings in the plate 47 and have the bolts 48 pass through the same, the springs being seated against the ends of the sleeves so that by operating the latter in either direction more the tension of the springs or less pressure may be imparted to said springs, the efl'ect of which is evident.
