SLOTTING, CREASING, AND SLITTING .MACHINE Specification of Letters Patent.

Patented July 14, 1914.

Application led April 25, 1914. Serial No. 834,334.

T0 all 'whom it may concern Be it known that I, HARLEY N. SICKLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Slotting, Creasing, and Slitting Machines, of which the following is a specification.

My invention relates to slotting and creasing machines, and more particularly to machines for slotting and grooving paperboard, paste-board, packing-board, and the like.

The object of my invention is to provide a machine which will slot and groove such board rapidly, accurately, and which is capable of being set to form slots and grooves as may be desired.

Further objects and novel features will be evident from the following specification and the drawings in which,-

Figure 1 is a side elevation. Fig. 2 is a plan view.- Fig. 3 is a rear elevation. Fig. 4 is a perspective of a piece-of board slotted and grooved by my machine. Fig. 5 is a detail of my slotting and grooving wheels. Fig. 6 is adetail section of my slotting and grooving wheels taken on a cutting radius. Fig. 7 is a similar detail taken on a grooving radius. Fig. 8 is an elevation of one of my cutting wheels arranged for continuous cutting or slotting.

Referring first to Fig. 4, I will explain the function of my machine. This perspective shows a sheet or piece of board in which the outer edges 2 and 3 ha? been cut true-the board being designated by the character 1. The slots 4, 4 have been formed and the uncut portions between the two sets of slots have been grooved or pressed so that the board will bend readily as shown at 5, 5.

Referring now to the other figures, the frame 6 of the machine has a table 7 upon which the sheets of board are placed one at a time. J ournaled in this frame are shafts 8 and 9, upon which sprocket- wheels 10, 10, 11,' 11 are rigidly mounted, and sprocket chains 12, 12, are carried by these sprocket-v wheels. Secured tol the sprocket- chains 12, 12, are feedin'gstrips 13,which feed the board to the rotating wheels that slot and groove the board. The machine is driven by a pulley 14 which is belted to a source of power.

Mounted upon the shaft 8 is a gear 17 in mesh with 'a pinion 15 which is journaled on the frame of the machine, and this pinion true the board 1 on the edges 2 and 3 as itV is fed through the machine.

Rigidly mounted upon the shaft 18 are the wheels 24, each of which has the peripheral groove or slot 25 and the upstanding shear edges 26 and 27. The width of the groove 25 is the width of the slots 4 to be cut in the board 1.

Rigidly mounted upon the shaft 2O are f the wheels 28, which coact with the wheels 24 to perform the slotting and grooving in the following manner: These wheels 28 are secured to their shaft by split-pulley hubs 29, so that they may be adjusted to form the slots in the desired places. Upon the peripheries of the wheels-28 areupstanding treads 29 which are in planel with the upstanding shear portions 27 on'the wheels 24. Mounted -upon the wheels 28. are shear segments 30 which are of the width of the groove 25 in the Wheel 24, and which are of the proper 'tread length and properly positioned to cut out the pieces of the board to form the slots 4, 4, and to force such cuttings down into the grooves 25, as clearly shown in Fig. 6.

Secured to a truss 31 which is placed transversely of the machine just back of the wheels 28 are curved guides 32 which have their free ends lying just above theftop plane of the board as it passes between the wheels. These guides hold the board down to prevent curling as it passes through the machine.

Mounted below and forward of the wheels 24 are Scrapers or cleaners 33, the free ends of which lie in the grooves 25 and clean out the cuttings forced into said grooves by the shear segments 30.

The speed in revolution of the wheels 24 and 28 and the sprocket chains 12, when two feeding strips 13 are used, is such that the travel is two to one; so that the incoming boards are .properly timed to cause the shear segments 30 to cut the. slots 4 in the right places.

, The operation is as follows: A board being placed upon the table 7, one ofthe feeding strips. 13. strikes its rear edge and forces. it forward at tlifepropei'itime for a set of the shear Asegments Qand the wheels 24 to engage it and cut t i'lfo'rward slots 4, and at the same time the shears21, 22 begin trimming the two edges 2 an'd'B. When the board has advanced until the forward Aset of slots 4 havebeen cut, the shear members 27 on the wheels 24 and the treads 29 on the wheels 28 press and groove the board .to form the grooves 5, as clearly shown in Flg. 7. At the proper interval the second setof shear segments 30 begin cutting the rear set of .slots 4, and continue cuttmg until the board passes out completed; and during these several operations the shears- 21,` 22 have completed the trimming of the edges 2 and 3; i

It will be understood that the wheels 24 and 28 are adjustable, as well as radially,

upon their respective shafts, so that the slots 4 may be spaced as desired. It will also be understood that shear segments 30 of various tread lengths maybe employed to vary the lengths of the slots 4. Also that any desired numbers of pairs of wheels may be employed to make any desired number of slots. f

It happensnot infrequently that I wish to cut from a single board more than a single piece, cutting the board entirely through at some point. This I accomplish by securing to a wheel 28 a set of segments 30 as shown in Fig. 8,' so that it cuts continuously. On theother hand, I may wish to roove a board at some point entirely across 1t without forming any slots., This I am able to do by removing all of the segments 30 from one of the wheels 28.

Having thus described my invention, I claim :-4
