Patented Oct. 29, 1929 e UNITED sTATes raras? Hermes HENRY c. THOMAS, or TORONTO, oNTARio', CANADA APPARATUS FOR FORMING A DECKEL EDGE UPON PAPERiSI-IEETS, GAR-DS, ORTHE LIKE Application filed November 7, 1 928. Serial No. 317,836.'
It :is customary to form on paper sheets, cards or the like a deckel edge in imitation of the regular deckel which occurs in the manufacture of paper. This imitation deckel has usually been done manually, the workman using a file or other tool to scratch or mark the edge of the sheet. This is a. comparatively slow and expensive method, and the obj ect of my invention is to devise apparatus bymeans of which paper sheets or cards may be provided with a deckel edge much more rapidly than by the hand process, andwhich will result in a superior finished article.
I attain my obj ect by providing on a rotary shaft a head carrying oneV or more series of cutters, the working face ofthe head being formed as a very flat cone, the inclination of the sides of the cone being preferably just suiicient to allow the cutters topass the lwork on its upward movement without engaging the work.
The apparatus is constructed in detail substantially as 'hereinafter described and illustrated in the accompanying drawings in which Fig. l is a side elevation of my improved apparatus;
Fig. 2 a plan view of part of the same Fig. 3 a rear view of the cutter head;
Fig. 4 a similar View of a modified form of cutter head; 1
Fig. 5 a section through a part of the cutter head; and l Fig. 6 a sectional detail illustrating the construction of the work support.
In the drawings like numerals of reference indicate corresponding parts in the different gures.
1 is a supporting frame, which may be of any suitable construction and is provided at its upper part with bearings 2 for the shaft 3. This shaft is provided at one end with a suitable pulley l by means of which it may be driven and at its other en d is'mounted the cutter headr. l y
This cutter head l5 lis the important feature of my invention and comprises a metaldisk having its working face formed asa very flat cone. The head is provided on its back with one or more ribs 7 and through the ribbed rportions yare formed holes to receive the cutters 6. Set screws 8 are threaded through the sides of the ribs to engage the cutters and lockthem in position. -By unscrewing the set screws, the cutters may be arranged to.
vin Fi g. 3. The latter, however, is preferable for the reasonthat when the cutters are arranged as shown in Fig. ,they engage the work substantially simultaneously and there,
is therefore a considerable ar on the'machine, whereas, when the cuttersV are arranged as shown in Fig. 3 there is a wider time .gap be-V tween `the engagement of the individual cuttersvwith the work and therefore the jar on the work and machine is considerably reduced. It will` be evident, of course, that other arrangements than that shownin Fig. 3 may be devised to cause the cutters to engage the work one .after the other. f
The work; 9 is supported on a platform, which is preferably, although not necessarily, movable to and from the working face of the head. The edge of the platform is arranged parallel to the downwardlymoving side of the conical face of the head, andthe inclination of the sides of the workingfa'ce need Vonly be sufficient for the cutters' to clear the platform on their upwardmovement atthe vopposite side.
It is important, vof course, that the work be rigidly supported adjacent the cutter head.
The platform, Win in aie-main be ofy meal, l' but I prefer to provide itwith a facing of wood, or other comparatively soft material, and it might even'be made of brass, copper, or other soft. metal not likely to injure the cutters. Vith this' arrangement the platform may practically touch the working face of the head and the cutters will themselves form their own grooves in the facing, the yfacing 12, which strip extends both in front of and below the platform, and is supported by a metal bar 13. The bar 12 of softer material is preferably 'formed with a separate facing 12, which may be glued to the main bar 12. When therefore through continued use the facing 12a becomes badly worn or damaged, it is quite a simple matter to replace it. The main advantage, however, is that the work may be supported quite close to the disk without the necessity of having to go to the trouble of providing special grooves for the passage of the cutters.
The platform is arranged to move to and from the working face of the head, being slidablymounted on guides 24. To actuate 'the platform I /fulcrum on the frame 1 the bell-crank lever 14 which with one end engages the under side of the platform, and its other end is connected by a link 15 to a footoperated lever 16. These parts are for the purpose of moving the platform towards the` head, while springs 17 mounted on the guides 24 are for the purpose of moving the platforni away from the head.
On the top of the platform I provide a guide for the rear of the stack of work, which guide is formed as an angle bar 18 having a pair of short slots 19 in each end of its horizontal leg.
Adjacent each side of the platform is a double row of holes 20, the holes in vone row being arranged in Ystaggered relationship to those in the other row. Bolts 21 are provided for securing the angle bar in any desired position. V I preferably thread through the vertical leg of the angle bar 18 and in these holes are threaded screws 22, on the ends of which is carried a guide'23. Y A very line adjustment is therefore possible without materially weakening the supporting platform.
The device is operated as follows. The stack of work is positioned on the platform and the head is caused to rotate. The platform is held in advanced position during cutting and then allowed to move away, the work then moved to a fresh position and the platform'again advanced. The platform is advanced and retracted and the work moved until the edge of the work has been sulfi- -ciently cut to produce the desired effect.
In actual practice, usually three or four moves of the stack will be sufficient, but this will naturally depend largely on the length of the work.
From the above description it will be seen that I have devised a construction which will satisfactorily attain the object of my invention as set out in the preamble of this speciication.
What I claim is: l 1. In apparatus for the purpose described, a rotary cutter head, its working face being formed as a flat cone having a cutting proj ection on said working face.
2. In apparatus for the purpose described, a rotary cutter head, its Working face being formed asa flat cone having a series of cutting projections on said working face.
3. In apparatus for the purpose described, a rotary cutter head, its working face being formed as a flat cone having a plurality of series of cuttingprojections on said working face.
4. In apparatus forthe purpose described, a rotary cutter head, its working face being formed asa flat cone having a series of cutting projections on said working face, said projections being arranged in a curved row.
5. In apparatus for the purpose described, a rotary cutter head, its working face being formed as a flat cone having a plurality of series of cutting projections on said working face, the projections in each series being arranged in a curved row. f
'6. In apparatus for the purpose described, a rotary cutter head having its working face formed as a fiat cone and a rib on its back, said cutter head having a hole formed through said working face and rib; a cutter in said hole, and a set screw threaded through the rib and adaptedto engage the cutter.
