MECHANISM FOR PRINTING BOXES.

. Patented Dec. 13, 19 10.

To all whom it may concern:

Be it known that I, HOWARD A. STILL- WELL, a citizen of the United States, residingat Woodbur county of Gloucester, and State of New Jiir and-useful Improvement in Mechanism for Printin Boxes, of which the following is a full, c ear, and exact description, reference being had to the accompanying drawings,

ing drawings, and then out the invention in the c aims.

which form a part of this specification.

My invention has for its object to auto matically print addresses, names or titles upon the sides orends of boxes and thus avoid the present cumbersome method of stenciling.

I will first describe the embodiments of my invention as shown in the, accompanyarticularly po nt Figure 1 is a general side elevation of the machine. Fig. 2 is an inverted plan view of the operating lever. Fig. 3 is a partial elevation of the opposite side of the machine.

"Fig. 4-iS a partial plan view on line 4-4,

by the cross piece g, which cross piece is connected by means of a bolt 72. in a longitudinal slot 2' in the side walls of the chute, so that the position of the cross piece 9 with reference to the length of the chute may be determined,- and thus the chuteis adjusted for varying sized boxes; Connected to this chute e is the spring j secured at the. other end to a fixed part of the machine. The chutee.

has a projection or car 70.

Z is a lever mounted on a rock shaft f and adapted in its movement inone direction to strike a projection on the ear or lug k and turn thehchute. nected by.means of the link me with the lever n pivoted at 0. When the lever 12 is allowed to fall at its outer end, it .will, through the medium of the before described mechanism, tilt the chute against the action of the spring, and when the lever 'nis raised, the spring j will move the chute backward, and by the weight of the chute,

sey, have invented a new,

This lever Z is conposition.

When the boxes are fed forward by the conveyer and onto the chute, and the lever fallsas described, the box is .tllted to a vertical position and placed. pon the rojectionof the truck 4. Thistruck is provide with the projectin pins 1' which enter the box' and steady thesame. This-truck is mounted on wheels a traveling in the frame t of the machine.

u is a pro'ection from the truck having the vertical'slot a in which is roller w. This roller is carried by and between'the chains g, which chains pass around the sprocket wheels 2. The roller 1 is mounted on the arm 2, projecting from the truck This roller lies beneath and against the ever n. The lower portionof lever-n is cam-shaped, as shown in Figs. 1, 2 and 3, so that, as may be seen, in the travel of the truck the'roller 1 will, during a portion of the movement of.

the truck, support the lever n .in its u per position, while in another portion 0 ,its movement it allows the lever to move on its pivot, tilting the chute, and in the return movement w1ll for a time maintain the lever down and then lift the lever.

The operation of the mechanism so far described. 1s as follows: With a box delivered into the chute and the truck in its forward position ready to'receive the box, the roller will be in such osition that the lever n will have moved on 1ts pivot to swing the chute, as shown in Fig. 6, the box being then received upon the'projection from thetruck, and the truck will move rearward, carryin the box. The movement of the true r through the medium of roller 1 will lift the lever,.allo.wing the chute to return to its horizontal POSltlOIl. The box carried by the truck will first pass under the printing rolls 3, which may be of any number, dependent upon the number of colorsor impressions desired. After passing under these printing rolls, the depending box strikes the pins 5 which projecting from the frame and extending over the truck, strikes the box at its upper end, and it will drop on the conveyer 6 below the truck, which conveyer car- 105 ries it out of the machine.

In order to (prevent a box being moved by the conveyor (1 while the chute is not in hori-- zontal position, I provide dogs or catches 7 connected to lever 25, which lever is acted it will be final-1y returned to its horizontal i .upon by the spring 8 to ,normally hold'the projecting from the truck 9 strikes the dog 15, which by contact with pin 16, moves the feeding of boxes and moving bar 11 to its wheel 29, on the shaft of which is the belt conveyer 6.

, manner: The truck is reciprocated backward wheel 32 for the conveyer a. 6 1s driven by means of a sprocket wheel 27 catches in their upright and operative position. The lever 25 is connected to the rod 9, which is in turn connected with the vertical rod or lever 10 connected at its upper end with the ba-r 11 extending along the frame of the I machine. At the outer end. of this rod is the locking device consisting of the latch 12 l pivoted on pin 120 adapted to lock with the detented end of the bar 11. This latch 12 is operated by the spring 13, one end of which is connected to pin 130 on latch 12. The other end of the spring is connected to the frame of machine. Mounted upon this latch'12 isthe striking-01f dog 14. This dog 14 is pivoted on pin 120.

140 is a pin 011 bar 11.

15 1811. dog. pivoted to the frame of the machine, and 16 is a pin upon the'rod or bar 11 contacting with said dog.

In the rearward movement of the truck 9 and after it has received a box, a pin 17 bar. 11 rearward until it engages and is locked by the locking latch 12. -This moves the stop 7 so that a box can be fed into the chute. On the further movement of the truck, thepin 1T strikes the releasing dog 1- moving it until its free end strikes pin 110, further movement raises that end of rod 11, lifting the detent out of engagement with latch 12, releasing the locking latch 12 and allowing the spring 8 to return the stops 7 tooperative position, thus preventing any forward position. O11 the return movement of the truck the pin 17 -passes freely the dog 15.

160 is a pin on latch 12 for limiting the downward movementof dog 14.

The 'parts are driven in the following and forward by the following mechanism leading from the pulley 18. Upon the shaft of this pulley 18 is the gear 19 which meshes with the gear 20. Upon the shaft of the gear 20 are the sprocket wheels 21.- These sprocket wheels 21, by means of the chains 22, drive thesprocket wheels on the shafts of which are one set of the sprocket wheels i The conveyer a is driven in the following manner: Upon the shaft of the gear' 20 is a pulley 24 which. by means of a belt 25, is connected with the pulley 26. Upon the shaft of this pulley 2-6 is the conveyor belt The conveyer on the shaft of the pulley wheel 26 from which a chain 28 passes to the sprocket It will be noticed that the lever n has'the cut-away po1't1on 6,las shown in Figs. 1'

and 2, which comes into action in the initial the printing rolls. 'It will'be noted further 1 that with this mechanism there is no danger of the box being broken in the operation, for the strain upon it at any. time 1sno greater than the weight of the pivoted lever 11.
