17 Claims.
This invention relates to an apparatus for cutting or severing sheet or web material such as veneer wall board or the like and has for its primary object to produce such an apparatus which is efiicient in operation, and simple in construction.
Veneer or sheet material of a like nature is usually formed from a continuous forming machine and in view thereof it is desirable to out such continuous sheet of material into the desired lengths so that the same may be used practically. It is desirable that the sheet material be cut into suitable lengths without interrupting the travel of the material and various types of machines or apparatus have been designed for accomplishing this result.
It is therefore another object of the present invention to provide an improved material severing apparatus which will fulfill these requirements and sever the material much more emciently.
It is a further object of the invention to provide settable means which cooperate with the material severing means' to actuate the latter to sever the material at the locations selected and to arrange such settable means so that the same is predeterminately operable to effect severance of the material at a location adjacent the selected settable member.
With the objects above indicated and other objects hereinafter explained in view, the invention consists in the construction and combination of elements hereinafter described and claimed.
Referring to the drawings.

Fig. 8 is a longitudinal vertical sectional view of a portion of the apparatus showing the relative position of the knife blades with respect to the anvil roll, one of the knife blades being shown in material cutting or severing position.
Fig. 9 is a fragmentary perspective view of one 5 end of the knife blade actuating bar.
In the drawings the apparatus is illustrated and consists of a frame It] made of angle irons or any other suitable material which is disposed in a horizontal plane and supported by suitable legs H. 10 This frame It) is provided with a transversely extending shaft I2 at its forward end which is suitably journaled at its opposite ends in bearings (not shown) secured to the end of the frame. The shaft [2 is provided with a plurality of sheaves l3 secured to the shaft 42 and spaced at intervals therealong. Belts l4 pass around the sheaves I3 at one end of the frame l0 and at the opposite end of the frame Iii about sheaves 15 secured to a transversely extending shaft l6 having its outer ends journaled in bearings I! more clearly shown in Fig. 4. These sheaves I5, like the sheaves l3 are likewise secured to the shaft l6 and receive the opposite ends of the endless belts 14 thereby providing a material supporting and conveying means for the loading end of the apparatus.
The frame I ll is further provided with transversely extending members I8 upon which is supported a plurality of longitudinally extending members 59 preferably of wood and upon which the belts M are adapted to ride. A roller 20 is rotatably mounted in one pair of the legs 1 I and positioned so as to engage the return portions of the endless belts it.
The discharge end of the apparatus consists of a frame 2! similar to the frame l0 except somewhat smaller and is supported in horizontal position and in the same horizontal plane as the frame ill by means of legs 22. This frame 2| is provided with a transversely extending shaft 23 having its opposite ends journaled in bearings 24 secured to the ends of the frame 2| and has secured thereto a plurality of sheaves 25 about which a plurality of endless belts 26 pass while the opposite ends pass around sheaves 21 secured to a transversely extending shaft 28 having its opposite ends rotatably supported in bearings 29. The belts 26 likewise form a suitable material supporting and conveying means at the discharge end of the apparatus and these conveyor belts I4 and 26 should preferably form a substantially continuous conveyor.
The frames l0 and 2| are spaced apart a suitable distance for a purpose to be later described and are held in spaced relation by means of angle members 30 more clearly shown in Fig. 4. The frame members are connected at their adjacent ends with side members 3! of a housing 32, the side members 3! or standards being preferably formed as a casting and connected at their lower ends so as to maintain them in spaced relation with a base 33. At the upper ends the side members or standards 31 are connected by spacer rods 34 so as to provide a rigid structure.
The bearings ll and 29 which support the ends of the shafts l6 and 28 respectively are bolted to the inner faces of the side members 3i as clearly shown in Fig. 4. Disposed between the shafts l6 and 28 is a drum 35 preferably composed of laminated wood and secured to its ends are stub shafts 36 rotatably journaled in vertically adjustable bearings 31 which in turn are secured to the inner surfaces of the side members 3|. This drum 35 is positioned so that the upper surface thereof will normally engage the under surface of the material M in a line transverse to the direction of travel of the material as shown more clearly in Fig. 8, and it is to be pointed out that it is along this line that the sheet material is severed during the severing operation.
It is important that the conveyor on the frame l and the conveyor on the frame 2| be driven at the same speed and to accomplish this feature the shafts I6 and 28 are provided with aligned sprocket Wheels 38 which are secured thereto and spaced at intervals therealong. Endless sprocket chains 39 pass around the sprocket wheels 38 on the respective shafts and lie within circumferential grooves 40 provided in the face of the drum 35, the portion of the sprocket chain at the top of the drum being sufilciently lowered so as not to engage with the under surface of the material M in its travel movement.
Directly above the drum 35 and in spaced relation thereto is the knife blade conveying means which consists of a plurality of transversely extending knife blades 4| which are supported in longitudinal spaced relation at their opposite ends upon conveyor chains 42 which pass around sprocket wheels 43, 44 and 45 respectively. The sprocket wheels 45 are secured to the opposite ends of a transversely extending shaft 43 which has its opposite ends suitably journaled within bearings 41 secured to the inner surfaces of the side members 3|. The sprocket wheels 44 are secured to a transversely extending shaft 48 having its opposite ends suitably journaled in bearings 49 secured to the inner surfaces of the side members 3|. The sprocket wheels 43 are secured to the opposite ends of a transversely extending shaft 50 which has its opposite ends supported in bearings secured to the inner surfaces of the side members 3|. The axis of the shaft 48 is in vertical alignment with the axis of the drum 35 and the shaft supports a drum 52 which is provided with circumferentially extending flanges 53 spaced apart longitudinally of the drum 52 for a purpose to be later described. I
The sprocket chains 42 which extend around the sprocket wheels 43, 44 and 45 respectively have secured thereto a plurality of castings 54 which have longitudinally extending circular slots 55 therein to receive correspondingly shaped members 56 secured to the ends of the knife blades 51. Coiled springs 58 are disposed between the ends of the blades 56 and the bottoms of the slots 55 and tend to normally maintain the blades 5! out of engagement with the material M or in other words in inoperative position. Slidably mounted upon the knife blade supports 58 are plates 59 having inwardly extending lugs 60 spaced apart longitudinally thereof to correspond with the spacing of the flanges 53 upon the roller 52, these lugs 60 being normally out of engagement with the flanges 53 as clearly shown in Fig. 6. These plates 59 have extensions 6! which extend outwardly and are adapted to be moved inwardly by a means to be later described, to move the lugs 60 on any selected knife blade support into alignment with the flanges 53 upon the drum 52 with the result that during the movement of the knife blade past the flanges 53 the latter will cause the knife blade 51 to be depressed to thereby sever the material M by reason of the engagement between the flanges 53 and the lugs 60.
'The severing of the material takes place as shown in Fig. 8 directly over the vertical axis of the anvil drum 35 and there being no relative separating movement between this roll and the roll 52 a positive severance of the material M is assured.
As many of these knife blades 51 may be employed as is desired and the spacing thereof should be such as to cover a wide range of lengths, the minimum length of course being between any two adjacent knife blades. It is also essential that the knife blades 51 travel in the same general direction as the direction of travel of the material M during the severing operation.
It is of course desirable to provide an auto-' matic means for shifting the member 59 so as to cause actuation of the knife blades 51 and this is accomplished by providing endless chain 62 which is supported at one end upon a sprocket wheel 63 secured to the outer end of the shaft l2 and at the opposite end upon a sprocket wheel 64 secured upon the outer end of the shaft 28, this chain extending preferably beyond the shaft 50. This chain 62 has mounted thereon a plurality of manually operable members or fingers 65 which are pivotally supported and adapted to be moved from their normal inoperative position to their operative position as shown in Fig. 5. Wherever it is desired to sever the material M one of these fingers 55 is-raised and in the travel of the chain 62 it engages a member 66 having an arrow head portion 51 at one end and being pivotally connected at 68 at the opposite end. The member 66 is normally under spring tension and its normal position is indicated in dotted lines in Fig. 7. The member 65 in its movement with the chain engages the arrow head portion 61 and forces the same inwardly about the pivot 68 where the opposite side of the arrow head engages with the extension GI on the slidable member 59 and moves the same inwardly as shown in Fig. '7. As soon as the member 65 has caused the member 66 to move the extension 6| inwardly to its innermost position, the member 65 passes beyond the arrow head portion 51 and the latter is returned to its normal position before any engagement with the succeeding extension, thereby insuring the operation of only one knife blade by reasonof any one manually operable member or finger 65. As explained before, engagement of the arrow head member with the extension 6| causes the slidable member 59 to be moved so that the lugs 60 thereon will lie directly in the path of the flanges 53 with the result that as the knife blade associated therewith approaches the roller 52 it will be depressed by engagement between the flanges 53 and the lugs 60 causing the knife blade 51 to sever the material M. When the knife blade has performed its severing operation and has passed therebeyond a cam 69 secured to the angle member 30 at the opposite side of the bar engages the adjacent lug 60 on the slidable member as shown in Fig. 4 and returns the same to its normal position, in which the lugs 60 are out of the path of the flanges 53. This slidable member 59 is more clearly shown in Fig. 9in detail. The fingers 65 upon the chain 62 are returned to inoperative position upon the return movement of the chain by means of a plate 10 attached to the frame I 0 adjacent the sprocket wheel'63 as clearly shown in Fig. 2 and the chain 62 is further guided in its movement by means of a sprocket wheel Ii secured upon the transversely extending shaft 20 and a sprocket wheel 12 rotatably supported upon the inner surface of the side 3|.
It is essential of course that all of these movable members be coordinated in such a manner that they operate properly and furthermore that the operation of the severing of the material is automatic. A main source of power in the form of a motor M is connected with a speed changer 13 which has a sprocket wheel 14 secured to the shaft of the rotor and is connected by a sprocket chain I5 to a sprocket wheel 16 secured upon the outer end of the shaft 28. An external gear 17 is also secured to the shaft 28 adjacent the sprocket wheel 16 and meshes with an external gear 18 secured to the end of the shaft 50 to thereby positively drive the shaft 50 directly from the motor 13. It will therefore be seen that in view of the fact that the sprocket wheel 64 is secured to the opposite end of the shaft 28 the chain 62 is driven directly therefrom. An external gear '19 is mounted upon the end of the drum 35 and is connected by a sprocket chain with a sprocket wheel 8| secured to the shaft 82 of a variable speed mechanism 83. The shaft 84 of the variable speed mechanism has connected to one of its ends a sprocket wheel 85 which is connected by a sprocket chain 86 with a sprocket wheel 81 also secured to the end of the shaft 28 adjacent the sprocket wheel 64. It will therefore be seen that through this variable speed mechanism the drum 35 may be rotated at the desired speed with respect to the travel of the material upon the conveyor.
