PAPER-SLOTTING MACHINE.

Specification of Letters Patent.

To all whom tt may concern:

Be it known that we, HENRY G. MGPIKE, J r., and HARRY B. HARLOW, citizens of the United States, residing at Alton, Illinois, have invented a certain new and useful Improvement in Paper-Slotting Machines, of which the following is a full, clear, and eX- act description, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of a cardboard slotting machine of our improved construction. Fig. 2 is an enlarged trans* verse section taken on the line 2-2 of Fig. 1. Fig. 3 is a detail section taken on the line 3&3 of Fig. 2. Fig. 4 is a detail section taken on the line 1 -1 of Fig. 2.

Our invention relates to a machine for slotting corrugated paper board, cardboard, thin veneer, and like material, used for the purpose of forming packing boxes and fillers adapted to inclose fragile articles during transportation or storage.

In packing small, fragile articles it is the practice to form a series of compartments or cells by arranging strips of corrugated paper board, or like material, at right angles to one another, and in order to do so the strips of packing material must be uniformly slotted in order to produce a structure having compartments or cells of uniform size, and we propose to provide simple, inexpensive means whereby the strips of corrugated board, or like packing material, are uniformly cut or slotted.

To the above purposes, our invention con sists in certain novel features of construen tion and combination of parts hereinafter more fully described and claimed.

In the construction of the machine shown, we employ a pair of side frames 1, the front portions of which are connected by a rail 2, on top of which is arranged a longitudinally disposed rib 3. Formed on the rear portions of the frames 1 are bearings 4C, in which is arranged for rotation a shaft 5 driven in any suitable manner, and arranged on said shaft 5 is a key or feather 6. A series of cardboard supports inthe form of rails 7 are arranged in pairs and extend from the rail 2 to the shaft 5, the under sides of the forward ends of said rails being slotted, as designated by 8, in order to receive the rib 3.

Arranged between the forward ends of each pair of rails 7 is a filler block 9, and carried by the forward ends of said rails 7 is a bearing block 10, which engages the front side of the rib 3. Passing through the lower portions of the forward ends of said rails 7 are set screws 11 which bear against the block 10 and force the same toward the rib 3.

The construction just described provides for the adjustment of the forward ends of the pairs of rails 7 longitudinally upon the rail 2, and also provides for the locking of said pairs of rails 7 after adjustment.

Fixed on top of the rails 7 are strips 12 of steel or hardened metal, the inner edges of which form cutting edges, which oppose the cutting edges of the knives or critters which pass between the pairs of strips 12 and pairs of rails 7.

Adjustably arranged on the rib 3 at one end of themachine, and preferably the right hand end thereof, is a block 13 carrying a rearwardly projecting vertically disposed plate 14, which forms a guide or gage against which the left hand end of the section of cardboard engages when said section is placed on the machine.

Blocks 15 are adjustably arranged on the rib 3 between the forward ends of the rails 7, and carried by said blocks are rearwardly projecting adjustable rods 16, the rear ends of which are bent upward to form fingers 17, which perform the function of gages and against which the rear edge of the section of cardboard is positioned when placed on the machine.

The rear ends of the rails 7 are provided with integral lugs 1S which encircle the shaft 5, and arranged to rotate in said lugs are collars 19 which fit snugly upon and rotate with the shaft 5 by reason of the key or feather 6.

Fitted on to the outer ends of the collars which hub is in the form of a ring which ts snugly between the rear portions of the rails 7, and passing through coinciding apertures.

formed through the collars 19 and the interposed hub 23 are rivets 24, or like fastening devices.

'By the construction just described, it will be noted` that the collars 19, lugs 21 and hub 23 are rotated with the shaft 5 and bear in the rings 18 formed on the rear ends of the brails 7.

Formed on or fixed to each of the hubs 23 is a cutter' arm 25 in the form of a plate of such thickness as to readily pass between the plates 12. One edge of the cutter is provided witli a series of points 26 having inclined cutting edges on either side of each point, forming a zigzag cutting edge, and this edge-of the plate or cutter performs the cutting or slotting operation as it passes between said plates 12. Any number of cutters and corresponding pairs of rails 7 may be located on the machine, and by loosening the set screws 11, the pairs of rails and cutters may be adjusted longitudinally and spaced the desired distances apart.

In the operation of our improved machine, the shaft 5 is rotated in any suitable manner, and the sections of cardboard, corrugated paper board, or veneer, are placed one at a time upon the pairs of rails, the left hand end of each section bearing against the gage plate 1&1, and the rear edge of said section bearing against the lingers 17. As the cutters 2,5 pass between the plates 12 located on the pairs of rails 7, the section of material will be slotted, said cutters making a shear cut through the material by reason of the points 26 on the edges of said cutters, and thus uniform and clean edged slots are formed in the material. At the time the slotting operation is performed, the rear one of the points of each knife iirst engages the cardboard, or like material, and in a measure clamps the same upon the supports without exerting any backward thrust on the material which is the case where the slotting device or cutter first engages against the rear edge of theV section of material. The succeeding points pass through the material, and as the edges of the cutters between said points are inclined relative to the horizontal plane occupied by the strips 12, a shear cut is made through the material, and whichv manner of cuttingfcan'be accomplishedwith an expenditure of little power.

A machine of our improved construct-ion is comparatively simple, is operated with very little power, is readily adjusted, and very rapidly performs the work of slotting cardboard, corrugated paper board, and like material, used for packing purposes.
