CARDBOARD-BOX KNIFE.
Application filed August 16, 1924. .Serial No. "(32,482.
This invention relates to a cardboard box knife. is object is the production of a knife which will quickly cut the cardboard of a box with a clan cut without injuring; the contents thereof. A second object is the production of a knife, which can be adjusted to cut through different thicknesses of cardboard or other material. so that the cutting; blade of the knife will cut the cardboard without coming in contact with objects below the same.
The organization of the invention comprises a knife and perforating wheel respectively supported and .journaled on an axle. The cutting edge of the knife and the perforating wheel are inthe same plane. The wheel perforates the cardboard or other material operated upon ahead. of the cut of the knifef The axle is fastened to a guide bracket and to the latter is adjustably secured a hub. An axle extends from the hub and on the latter is journaled a guide and supporting wheel. A roller is also provided for the blade. which with the guide and supporting wheel maintains the cutting edge of the knife blade in proper position.
in the accompanying; drawings Fig. 1 represents a side View of a knife having the invention incorporated therein; Fig. 2 shows a top plan view of Fig. 1: Fig. 3 indicates a partial left hand side view of Fig. 1 with an element omitted; Fig. 4 is a section of Fig. 1 on the line 4;. (t; Fig. 5 represents a right handL side view of Fig. 1 with an elemcnt omitted and a slight modification; Fig. 6 indicates an enlarged. right hand side view of a portion of Fig. 1. and F 7 shows a left hand side view of a portion of Fig. t.
The knife comprises the knife blade 10 having the curved nose 11 with the teeth 12 at one end, and the handle 10 at the other end. The nose 11 is curved at 14- to locate the cutting edge 15 in proper position.
A bracket 16 is shown with the recessed portion 17 forming the wall 18 in the bracket, at right angles to said recessed. portion. An elongated opening 19 is formed in the recessed portion 17 and teeth 26 are formed in the wall 16 which mesh with the teeth 12 of the nose 11. A stud 21 is secured to the nose 11, and extends through the clongated opening 19. A nut 22 for said stud provides means to clamp the bracket 16 to the nose 11. A roller 23 is journaled to the lower end of the bracket 16. The bracket 16 can be clamped in diflerent positions to the nose 11'to locate the roller 23 at different levels.
An axle 25 with the enlarged head 26 supports the knife blade 10. A perforating wheel 29 is ournaled on the axle 25. and its plane is in line with the cutting edge 15. A disc bracket 80 with the annular flange 31 is fastened to the end face of the axle 25, by means of the screw 32 and the dowel pin A pair of oppositely positioned adjusting screws 34 extend through the flange 31. A hub 35 has formed therein the oppositely positioned guide openings 36. Guide screws having the heads 37 extend through the openings 36 and are in threaded engagement with the disc bracket 80. The guide screws maintain the hub 35 against the face of the disc bracket 30. An axle 10 has one in threaded engagement with the hub 35, and has journaled therein a guide and supporting wheel 42. The cardboard or other material through which the knife cuts is indicated at 4:5.
To use the knife it is held by the operator in the position bestshown in Fig. 1 with the roller 23 and the wheel 42 bearing on the cardboard 45 of the box or container to be cut,and drawn in the direction of the arrow A.
The perforating wheel 29 will insert a series of openings in the cardboard to provide a path for the cutting; edge 15 of the knife blade 10. The roller 28 and the supporting wheel 42 maintain the cutting edge 15 at the proper depth below the top surface of the cardboard. and the roller 23 also smooths the surface of said cardboard adjacent to the cut made therein. To adjust the knife for various thicknesses of cardboard to be cut, the distance between the axial. center lines of the axles 25 and 40 is adjusted, by means of the adjustingscrews 34: and the screws having the heads 37. The latter screws are first unscrewed, and then one of the screws 34; is unscrewed and the other screw 34: is turned to locate the hub 35 with respect to disc bracket 30 in the required position. Finally the screws with the heads 37 are again screwed in place. By this meansthe longitudinal axes of the axles 25 and 40 are located coincident with each other or separated from each other. Atthe same time the bracket 16 is clamped in proper position to the nose 11 of the knife blade 10, by
means of the stud 21 and the nut 22. By this means the lower end of the cutting edge 15 and the periphery of the perforating wheel 29, will be located in proper position with respect to the periphery of the wheel 42 and the roller 23, to cut the cardboard to just the depth required. The knife may be used without the bracket 16 and its roller 23, in which case the teeth 12 in the nose 11 may be omitted as indicated in Fig. 5. The knife may also be used without the perforating wheel 29.
Various modifications may be made in the invention and the present exemplifieation is to be taken as illustrative and not limitative thereof.
Having described our invention what we desire to secure by Letters Patent and claim 1s:
1. In a knife of the character described the combination of a knife blade, a guide and supporting wheel for the knife blade, means to adjust the location of the supporting wheel and a roller adj ustably connected to the knife blade.
