UNITE STATES CHARLES EVERETT GOLGBOVE, 0F TORONTO, ONTARIO, CANADA.

LINER MACHINE.

Application filed October 11, 1923.

To all whom it may concern:

Be it known that 1, CHARLES EVERETT CoLoRovn, a subject of the King of Great Britain, residing at No. 142 Delaware Ave, in the city of Toronto, in the county of York, in the Province of Ontario, in the Dominion of Canada, have invented a new and useful Liner Machine, of which the following is a specification.

Statement of intention.

The present invention relates generally to the art of corrugated straw board manufacturing machines, and to liner machines specifically, as described in the present specification and shown in the accompanying drawings.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

Those skilled in the art will appreciate that the manufacture of corrugated strawboard consists of five principal steps, namely: corrugating the straw-paper for the center ply; applying the first liner; applying the second liner; drying and setting the board; and slotting, creasing, trimming, and cutting. My invention relates to the drying and setting of the board and to the means for advancing the board to undergo the slotting, creasing, trimming, and cutting process, and to facilitate a comprehensive elucidation, thereof, I shall give a brief dissertation on the methods and mechanism in the art.

In the usual method, as soon as the second liner is applied, the strawboard passes through a drying device. This may be a platform of heated platens over which the strawboard slides, being held down by cocoa mat, or it may be a series of heated platens above the strawboard with the strawboard held against them by a plurality of brushes.

The said strawboard is fed from the drying means to the cutting means. Cutters are of two different kinds called rotary cutters and guillotine cutters. In rotary cutters a heavy, rigid iron frame holding a knife-bar runs horizontally across the line of travel of the board. This frame is mounted on pivots on the ends and at such a height that when it rotates it brings the knife plate down and across the straw- Serial No. 667,885.

board. The delivery table along which the board travels from the drying platens terminates with a tapered steel sheering plate, and the strawboard is out between the rotary knife and the sheering plate. The rotary speed of the knife is timed with the travel of the strawboard, to endeavor to cause the cutter to work without stopping the strawboard to prevent buckling or bending.

Tn guillotine cutters a steel knife plate is set across the line of travel of strawboard on a heavy frame which falls and rises, cutting the strawboard against the plate edges as it falls, and then rising clear of the strawboard to allow it to travel on. To prevent the strawboard from buckling while the knife is down, the cutter in the sheering plate slides back and forth, travelling with the strawboard while the knife is cutting, and back again when it is raised clear.

The objects of my invention are, with the foregoing in View, to provide a machine for receiving the strawboard from the lining machine and for tensioning the same intermediate heated coacting reciprocating platens which serve to advance the strawboard intermittently to the slotting and creasing machines, the advancement thereof being susceptible of adjustment to accord with the different sized sections to be made; to provide means for advancing the strawboard intermittently so that upon each cessating thereof the slotting and creasing portions may be effected; and to provide means for intermittently advancing the strawboard to the cutters which sheer the board during each cessation of the advancement thereof, thereby obviating the necessity of providing means for reciprocating the cutting mecha nism longitudinally of the strawboard to prevent buckling and bending.

Supplementing the advantages afforded by the setting and drying means, are those derived from the intermittent strawboard advancing means incident to the precision of each sequential advancement, which reduces to a minimum the amount of waste and obliterates the necessity of labor, as is now required.

In the drawings:

Fig. 1 is a side elevation of a liner ma chine constructed in accordance with an acceptable form of my invention, the liner platens being shown in their extended positions.

Fig. 2 is a similar view illustrating the liner platens in contiguous relation.

Fig. 3 is a vertical sectional elevation as it would appear when taken on the plane indicated by the line 33 in Fig. 1, and

Fig. 4 is a longitudinal vertical sectional elevation as it would appear when taken on the plane indicated by the line 44 in Fig. 3.

Like numerals of reference indicate corresponding parts in the different figures.

The term drive, as herein used is intended to designate any appropriate form of driving mechanism for reciprocating the platens of the machine in the required man-.

ner, and in view of such a very brief description thereof is deemed adequate for the purpose of this disclosure.

The numerals 1, 2, 3 and 4 designate standards mounted upon the I beams 5 and 6 which form the base of the machine. Numerals 7 and 8 designate beams which serve to form a bed for the reciprocating platens, designated in their entirety by the numerals 9 and 10.

Spur gears 11 are rotatably mounted upon the arbors 12 integral with each standard, and are driven by the pinions 13, said pinions being driven by the intermediate pinions 14 carried upon the drive shaft 15, which is journalled in the adjustable hearing 16 and 17 carried by the castings 18 and 19, detachably mounted between the standards 1 and 3, and 2 and 4, respectively. The numeral 20 designates a drive pulley driven by the belt 21 from an overhead drive. The numerals 22 and 23 designate shafts extending between and carried by the standards 1 and 2, and 3 and 4, respectively. The said shafts serve to act as hinge pintles for the rocker arms 24 and 25, and 26 and 27, which have bifurcated extremities 28 forming yokes which serve to straddle the pintles 29 carried by the member 30. Said rocker arms are driven from the spur gears 11, being connected thereto by the connecting rods 31, 32, 33, 34, which straddle the intermediate portions 35 of the rocker arms as at 36, being connected thereto by the pintles 37, while the adjacent extremities thereof are connected to the arbors 38 integral with the spur gears 11.

The platens designated in their entirety by the numerals 9 and 10 are each formed of upper and lower coacting sections 39 and 40, the coacting bases of each, section being preferably formed of sheet steel, as designated by the numerals 41 and 42.

As before premised, the drive mechanism previously elucidated is for the purpose of reciprocating the said platens for intermittently advancing a web of strawboard shown and designated at A. The means for controlling the coactions of said upper and lower sections 39 and 40 constituting the reciprocating platens includes rail plates 43 and 44, mounted upon each extremity of the lower sections 40 of the reciprocating platens, said rail plates bearing upon the beams 7 and 8 forming the bed of the machine. Numerals 45 and 46 designate eccentrics, connected as at 47 to the rods 48 which extend transversally of the upper platen section 39 and connected to eccentrics, 49 and 50 likewise mounted upon the rail plates 44. The numerals 51 designate members which may be cast integral with the rail plates referred to, or may be connected thereto as preferred, having pivotedly connected thereto the dogs 52 positioned intermediate the stops 53 and 54 mounted upon the eccentrics actuating bars 55, which are pivotedly connected to the eccentrics 45 and 46, as at 56.

The mechanism for actuating said platen controlling mechanism includes two pair of stop members, each of which pair is designated by the numerals 57 and 58. The stop members 57 are adjustable longitudinally upon the bases 60 through the medium of the hand wheels 61, and appurtenant mechanism. Each stop member 58 also carries a dog as shown in dotted position and designated by the numeral 62. The numerals 63 designate indicators carried by the said stop members 58 which serve to indicate, by coincidence with the graduations configurated on the side of the beam 7, the position of said stop member with respect to the platens. Said stop members 58 are adjustable longitudin ally upon the bases 64 through the medium of the hand wheels 65, and their appurtenant mechanism.

The upper sections 39 of each platen is guided vertically upon the pins 66 carried by the lower sections 40.

The numerals 67 and 68 designate steam pipes which extend longitudinally of the machine and through the lower sections 40 of each platen; said steam pipes serve to heat the center of the web of straw board as it is advanced to expedite thorough drying of the same.

General operation.

As before premised, the principal object of my invention is to advance the web of strawboard to the trimming and slotting machines intermittently and sequentially; each sequential advancement being predetermined by the adjusting of stop members 58. Presuming that it is desired to advance the web of strawboard step by step, the steps being 16 inches and 24 inches in length. respectively, the stop members 58 are adjusted to the positions shown in Fig. 1; that is to say, the indicators 63 coincide with the 16 and 24 inch graduations configurated on the side of the beam 11. Presuming that the platens are in the position shown in Fig. 1, the upper section 39 of the platen 9 is bearing upon the strawboard, due to the fact that upon the previous return of the said platen the dog 52 striking the dog 59 of the stop member 57 lowered the said section 39, bringing about the coaction of the said platen to grip the strawboard. In this position the platen desig nated in its entirety by the numeral 10 is at the opposite extremity of the machine; the section 39 thereof being elevated above the strawboard which is free to advance therebeneath; this being due to the coincidence of the dog 52 with the dog 62 of the stop member 58 for that respective platen, which serve to force said dog latterly to the position shown, which resultantly acted upon the eccentrics 45 and 4:6 to bring the same into the position illustrated, which brought about elevation of the section 39 of said platen.

From this position the oscillating rocker arms 24 and 25, and 26 and 27 reciprocate the platens towards each other to the position illustrated in Fig. 2. Upon advance ment of the platen 9, from the position illustrated in Fig. 1, the dog 52 abuts against the dog 62 carried by the stop member 58, which serves to swing the said dog member latterly and assume the position shown in Fig. 2, said movement serving to act upon the eccentrics 45 and 46 to elevate the section 89 of the platen from the strawboard, which incidentally cessates. The said platen then advanced to complete its cycle of operation irrespective of movement of the strawboard. Retrogradation of the platen 10 is synchronous with the advancement of the platen 9, and upon coincidence of the dog 52 with the dog 59 of the stop member 57 for that platen, the same is caused to assume its vertical position, as shown in Fig. 2, which acts upon the eccentrics 45 and 46 to bring about the lowering of the platen 39; coacting the sections to engage the strawboard and advance the same sequentially after the advancement thereof by the platen 9. When said platen has advanced the strawboard 24 inches, to which the indicator 63 is adjusted, the dog 52 strikes the dog 62 carried by the stop member 58 which actuates the eccentrics to elevate the section 39 of the platen and clear the same from the strawboard which is free to be advanced by the platen 9.

The weight of the upper sections 39 of each platen when down bear upon the strawboard as it is advanced, tensioning the liners against the corrugated web, and resultantly expediting the setting of the same in a substantial manner.

It is obvious that the travel of the platens will be such as will provide an intermittent cessation following each sequential advancement of the strawboard, during which time the slotting, trimming, creasing and cutting off machines may operate upon the strawboard.

It is also to be appreciated that this disclosure is for the purpose of illustration only and that deviations from such detail and the construction and actuations thereof may be resorted to as do not form a departure of the spirit of the invention and the scope of the appended claims.
