To all whom, t may concern; side elevation of the glue-roll mechanism, Be it known that I, WILLIAM S. SCALES, a showing the cam for giving straight-line m-v citizen of the United States', and a resident of` tion to the glue-roll latched in its lowermost Boston, in the county of Suffolk and Stateof position and causing the glue-roll to clear the 55 Massachusetts, have invented certain new under surface of the block.

Fig. 2 is a plan View similar to at 212 to the fixed support 213. Pivoted at` Fig. 1, showing the throw-out mechanism for 21S to the fixed support 213 is a bellcrank the latch in the position in which it is left lever 219, one arm of which is connected by after the passage of the block without a carlink 220with `the lever 105 vandv the other ton, the latch being thrown in. Fig. 3 is a arm of which is connected by rod 221 with 95 side elevation looking toward the lleft in Fig. one end oflever 222, fulorumed at`223. Y The 1, showing the cam for actuating the glue-roll other endl of lever 222 has a cam-roll 224, and cam for giving the straight-line motion which engages with a cam 225 on shaft 27, to the glue-roll, said cam being in its upward and through the connections described lever position with the latch thrown out and the 219 is actuated to oscillate the lever and loo 5o glue-roll engaged with the under surface of reciprocate the glue-roll 63. It is obvious the carton-Hap. Fig. 11 is an enlarged detail that if the pivot 5 were fixed the glue-roll 63 would move onlyin the are of a circle. Arm

' 211, however, to which lever 105 is pivoted,

is itself pivoted at both ends, and the pivot 5 forms a movable fnlcrum for lever 105. Carried on the lower end of lever 105 is a roller 214, which moves in a cam-path 215 in the cam 216. The cam-path is so formed that when the cam 216 is in the position shown in Fig. 3 and the lever105 is actuated by the rotation of the cam 225 the tendency of the upper end of the lever and of the glue-roll to describe an arc of a circle will be compensated bythe movement of the lower end during a part of its stroke, and the resultant motion will be in a straightline during that portion of its movement where the glue-roll passes under the block 6 and its attached carton 260.

It is not important to have the glueroll move in a straight line except where it passes in engagement with the carton-fiap on the block. It is rather desirable that it should move out of its straight-line path aty the end of its stroke, so as to be out of the path of the carton and block during the rotation of the spider-head. The dotted line 217 217 shows the path described b v the center of the glue-roll.

The parts are so adjusted that when the cam 216 is in the position shown in Fig. 3 the rectilinear path of the glue-roll 63 when it passes beneath the carton-block 6 will be at the right height for the glue-roll to contact with the carton-flaps and apply the glue. It is desirable, however, to provide means by which if the block 6 has no carton upon it the glue-roll shall not rub across the lower end of the block, because such engagement will leave a film of glue on the block, which will be objectionable and will cause the carton to stick to the block the next time around when a carton is placed upon it. In order to provide for this, the cam 216 is made movable, and mechanisms are provided by which the said cam will be automatically locked in the position shown in Fig. 3 if a carton is on the block and by which if a carton is not on the block the said cam will be lowered and locked in its lower position during the reciprocation of the glue-roll, so that the glue-roll will not engage with the block. The mechanisms for accomplishing this are as follows: One end of cam 216 is pivoted at 248 to the fixed arm 213. The cam maybe turned upand down on itspivot. Two stop-

pins

249 and 250 limit the up-anddown movement. The unpivoted end of the cam 216 rests on a finger 251, pivoted at 252 to the fixed support 213 and is normally held by a spring 253 in a position to retain the cam 216 in its uppermost position,as shown in Fig. 3. A shoulder 254` prevents the spring from throwing the finger 251 too far over. Rising from the table 31 is a column 226, having a long bearing 227, which forms a journal for a tubular shaft 228. Fast to or integral with the tubular shaft 22S is a finger 232, which projects into the path of the carton-block 6 and is engaged thereby each time the spider makes a turn through the arc of movement to bring the block and carton into position for gluing. (See Fig. 1.) Rising from the table 31 is another column 233, having a long bearing 234, which forms a journal fora tubular shaft 235. Said shaft is supported in a manner similar to shaft 228. Fast to or integral with tubular shaft 235 is a finger 238, which intersects the cylindrical plane in which the carton-block 6 moves. It is, however, below the block far enough so that it does not intercept the block, but is high enough to he engaged by the depending flap 60 of the carton 260 if a carton is on the block. Fast to or integral with the tubular shaft 228 is an arm 239, to the other end of which is pivoted one end of a connecting-rod 240. The other end of said connecting-rod is pivoted to one end of an arm 241, which is fast to or integral with tubular shaft 235. Fast to or integral with tubular shaft 235 is an arm. 242, to which is pivoted one end of a connecting-rod 243, the other end of said connectingrod being pivoted to a link 244, which is pivoted to a hook-lever 245, having a hook-catch 246. Said `levor 245 is pivoted at 247 to the fixed support 213. Projecting from bellcrank lever 219 is a finger 255, which when the said lever is rocked by the cam 225 through the connecting mechanism in a direction to move the glue-roll 63 toward the glue-feed roll 123, as shown in Fig. 4, will engage finger 251, on which rests lever 216, and will turn it down out of engagement with said cam, compressing spring 253. A cam finger or boss 256, also projecting from bell-crank 219, will engage with a stud 257, which projects from the side of cam 216, and cause the cam 216 to be turned down on its pivot. This movement will occur while the spider-head is movingthrough its arc of movement. When the spider-head moves,the block 6 engages during its course the finger 232 and partially turns the tubular shaft 228 on its journal, and through the connections already described it also turns shaft 235, thereby moving connecting-rod 243 in a direction to cause the hook-latch 246 to hook over onto the upper side ofa projecting shoulder 258 on the rear end of cam 216 and hold the cam in its lowermost position, resting on the stop 250, as shown in Fig. 4, and unless the latch 246 is in some way tripped before the glue-roll passes back under the carton-block the lever 105 will not reach high enough to cause the glue-roll to come in contact with the block. This condition is shown by the dotted lines in Fig. 4.

Mechanism is provided by which the latch will be tripped only when a carton i's on the block. The outside corner of the downwardly-projecting flaps at the lower end of the advance side of the carton-block will engage the finger 238 after the finger 232 has caused the latch to engage the cam 216 and will canse llO tubular shaft 235 to turn in the reverse direction to its formerturning and through the connecting mechanism will release the latch 246 from the cam 216. It will also through the connecting mechanism turn tubular shaft 22S back again and bring finger 232 into position to be engaged by the next following block 6 at the neXt movement of the spider-head.

When the lever 105 turns so as to carry the glue-roll from the feed-roll, as shown in Fig. 4, back under the carton-block 6, the bellcrank 219 will be turned back and the linger 256 will be withdrawn from the stud 257, and the finger 255 will be Withdrawn from the pivoted cam-supporting 1inger251,and the spring 253 will turn said supporting-finger 251 upon its pivotinto engagement with the under side of cam 216. If the latch 258 has been released by a carton on the4 block, the said finger 251 will lift the cam 216 up into its normal position, so that the fulcrum oflever 105 will be raised high enough for the glueroll to pass in contact'with .the carton-flap.

. If a carton is .not on the block so as to release the latch 246, the spring 253 will not be able to turn back the finger 251 its full distance and the cam 216 will remain thus latched until a block does come around with a carton thereon and engage the finger 238 to trip the latch.

Mechanism for folding the flaps is not shown herein, as thatdoes not form a part of the present application. They may be folded in any suitable way either automatically or by hand.

Shaft 27, on which the glue-roll-actuating cam 225 is mounted, is connected by bevelgear 144 With/bevel-gear 141 on shaft 74,which carries the driving spur-disk '7, so as to produce harmony of movement. (See Fig. 3.)
