Application filed July 26, 1909. Serial No. 509,561.

Patented May 3, 1910.

To all whom/it may concern:

Be it known that I, FnANK'BnsALn, citizen of the United States residing at C0- shocton, in the county of Coshocton and State of Ohio, have invented certain new and useful Improvements in Double-Facers, of which the following is a specification.

This invention relates to machines for applying facin" to corrugated paper and more particularly to a machine for applying a second facing sheetto single faced corrugated paper. 1

The object of the invention is to provide a machine of simple and durable construc- 3 5 tion, by means of which one or more facing sheets may be applied to a corrugated strip and the composite sheet cut into predetermined lengths at one operation of the inachine.

A further object is to provide a facing machine, the construction of which is such that both sides of the corrugated strip are heated and held in contact with the facing strip during the passage of said strips through the machine thus preventing cupping of the resultant product and producing a smooth straight. composite sheet.

A further object is to provide a cutting device including an oscillating frame having 3 a blade mounted for reciprocation thereon and operatively connected with the strip feeding mechanism, said cut-ting device being actuated intermittently to cut the double faced corrugated strip into predetermined lengths.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efliciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted. to within the scope of the appended claims. 7

For a full understandin of the invention and the merits thereof an also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a double facing machine constructed in accordance with my. invention; Fig. 2 is a longitudinal sectional 'view of the same; Fig. 3 is a plan view; Fig. 4 is a transverse sectional view taken on the line 44 of Fig. 3; Fig. 5 is a perspective view of the cutting-mechanism and the adjacent portion of the supporting frame.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

The machine forming the subject matter of the present invention is principally dcsigned for applyin a second facing to a corrugated strip a tor the latter has been passed through a corrugating machine and the first facing appliec thereto.

The machine comprises a supporting frame including spaced side walls 5 having depending feet 6 bolted or otherwise rigidly secured thereto and upon which is mounted a casing or housing 7.

J ournaled in the side walls 5 of the sup porting frame, are a series of spaced horizontally alined feed rollers or c linders 8, the latter bein hollow and pre erably extended the entire width of the casing 7, as shown.

Disposed beneath the feed rollers 8 and preferably arranged in vertical alinement therewith,are similar feed rollers 9, whichin conjunction with the rollers 8 serve to press the facing strip in contact with the corrugated strip as said strips are fed through the machine.

The upper and

lower feed rollers

8 and 9 are hollow to provide steam chambers 10, in order that the rollers may be kept at the proper tem erature to insure drying of the paste or ot er adhesive material applied to the corrugated strip.

Each feed roller is provided with oppositely disposed spindles 11 which project through bearings 12 in the side walls 5 of the supporting frame, there being suitable pockets 13 formed in the side walls 5 ber neath the projecting end of each spindle 11. The up r ends of the pockets 13 are open, while t e lower ends thereof are provided with threaded apertures for the reception of set screws It by means of which the distance between the adjacent rollers may be regulated so as to accommodate strips of paper of different thicknesses.

The spindles 11 on one side of the machine are rovided with iongitu'dinal openings whic communicate with the steam chambers '10 and in which-are seated the. sleeves or bushings 1 5 of suitable sprocket wheels 16.

be bushings 15 are secured to the adjacent Steam supplied to the compartments 10 of the several

drums r rollers

8 and 9 thrrugh pipes or conductors 18, two of which are preferably ,citt'ndcd through each bushing to. One of the pipes 18 of each drum or roller is connected with a main supply pipe it), while the other pi pc 18 is connected with an exhaustpipe It so that the steam enterthrough the pipe 19 is free to circulate within the compartments it) and exhaust into the pipe :20, there being a suitable steam trap 21 operatively connected with the pipes 19 and at the forward end of the machine, as shown.

Disposetlwit-liin the casing or housing 7 and interposed between the feed rollers or drums, are steam chests. the abutting faces of the steam chests being flat and unobstructed and spaced apart to permit the passage of the corrugated strip and facing strip through the machine.

The steam chests 22 are connected by branch pipes 23 so as to allow a continuous circulation through the several steam chests for the purpose of maintaining the latter at the proper temperature, steam being admit.- ted to the upper and lower steam chests at one end of the machine through a pipe or conductor 24 and being exhausted from the steam chest at the other in the machine through a similar pipe or mniluctor 25 communicating with the pipe 9:).

The upper series of rollcrsor drums are driven by a sprocket chain .27 engaging the sprocket:- whecls to, while the lower set or series of rollers 9, are driven by frictional contact with the paper strip as the latter passes througn the mach ne.

One of the drums or rollers 8 of the upper series 'is provided with a relatively large sprocket wheel 28, which latter is connected through the medium of a sprocket chain 29 with a motor engine or other source of power, thereby to rotate the several feed rollers or drums.

A sprocket chain 30 engages the teeth of the-sprocket'wheels 16 on the lower set or series 9 in order that said rollers may rotate in unison.

Extending laterally and upwardly from vone end of the machine, are spaced brackets 31 having terminal bearings 32, in which is journaled a spool or spindle 33 carrying a roll of facing paper 34, which latter is fed throught-he machinetogether with the corrugated strip 35 and secured to the latter in order to produce the composite sheet, indicated at 36. r f

Disposed beneath the spool carrying bracket 31, is a second bracket 37, to which is secured in any suitable manner, a paste l l I cup or tank 33. Mounted for rotation within the paste cup or tank 38 and ournaled in suitable bearings :39 in the bracket 57, 1s a roller 40'which applies the paste or other adhesive material in the cup to the adjacent faceof the corrugated strip 35 as the latter is fed through the machine. Journaled in bca rings in the lower portion of the bracket 37, are a plurality of feed rollers 41, each having one end thereof extended to form a spindle 42, to which is secured a sprocket wheel 43. A sprocket chain 4-1 engages the sprocket wheel -13 of the feed rollers and also basses around a sprocket wheel +5 on the spindle of the paste applying roller 40, the latter being provided with a similar sprocketwheel at) which engages the sprocketchain 27 so that motion may be transmitted through the medium of the sprocket chain 2-? to the pas e applying roller 40 and thence through the medium of the chain 41 to the feed rollers 41, as best shown in Fig. 1 of the drawings.

The supporting feet or legs at the front of the machine are extended laterally and provided with horizontally alined bearings -17, in which is mounted for rotation a transverse shaft -13 having spaced eccentrics 49 secured to the opposite ends thereof and which co-act with suitable eccentric straps 50.

Mounted for oscillation on the shaft 48, is a'franv), the side bars oi of which are pivotally mounted at their lower ends on the shaft 48, while their upper ends are. formed with vertically disposed slots 52, in which is mounted a reciprocating cutting blade or knife 53. The opposite ends of the cutting blade 53 are reduced and projected through the 57 52 for connection with vertically disposv ods 54, said rods forming a connection between the eccentric straps 50 and the opp-site ends of the cutting blades as best shown in Fig. 5 of the drawings. Connecting the bars 51 of the oscillating frame beneath the slots 52, is a bed plate 55 which coach; with the knife 53 to cut or sever the composite strip into predetermined lengths.

Motion is imparted to the oscillating frame 51 by means of an arm 56, one end of which is secured to the adjacent side bar of the frame 51, while the other end thereof extends above the sprocket chain 31 and is provided with a terminal lip or finger 57. which latter extends into the path of move ment of an actuating finger or lug 58 carried by the sprocket chain 30. Thus it will be seen that as the sprocket chain 30 rotates, the pin or lug 58 will intermittently engage the finger 57 of the arm 56 and force the oscillating frame 51 laterally to the dotted line pos tion shown in Fig. 1 of the drawings, said oscillating frame being returned to normal or vertical position by means of a (2011 spring 59 operatively connected withthe frame 51 and supporting frame 5.

*shoosely mounted for rotation on one end of the transverse shaft 48, is a wheel or pulley 00, over which travels a belt 61 leading to a motor or other suitable source of power for actuating the cutting blade 53.

The inner face of the wheel or pulley (S0 is provided with a clutch member 62, there being a similar clutch member (53 keyed to the shaft 48 and adaptcdto engage the mating clutch member (3:2 for transmitting motion from the pulley GO to the shaft 48.

livotally monnted at 64 on one of the side members of the oscillating frame 51, is a lever (35, one end of which is bifurcated for engagement with the movable clutch member 03 so that when the lever is tilted, the clutch members (32 and 63 will be moved into and out of engagement with each other.

The free end of the operating lever 65 travels in the path of an inclined bar or cam 66 carried by the supporting frame 5 so that when the oscillating frama 51 is swung latorally away from the machine, the lever 65, by engagement with the cam 66, will actuate the clutch membersto key the pulley (30 on the shaft 48, thereby to actuate the knife and cut or sever a predetermined length of the composite strip.

In order to disengage the

clutch members

62 and 63 after each downward movement of the knife 53, there is provided a spring (37, one end of which is secured to the lever 65, while the opposite end thereof is secured to one of the side members of the frame 51. Thus it will.- be seen that when the lug 58 engages the lip on the arm 56, the oscillating frame 51 will be swung laterally, thereby causing the cam 66 to trip the lever 65 and throw the

clutch members

62 and 63 into engagement with each other and rotate the shaft 48 A- the shaft 48 rotates, the coccntrics49 will actuate the rods 54 to lower the cutting blade 53 in the direction of the plate 55 and cut or sever the composite strip. After the lug 58 is disengaged from the arm 5! the spring 59 will automatically return the frame 51 to normal or vertical position, and in doing so cause the cam 66 to actuate the lever 65 and disengage the clutch members 03 so that the cutting mechanism will remain dormant. until the lug 58 again engages the finger on the arm 56, in the manner before stated.

The casing or housing 7 is preferably lined with a jacket of asbestos 68, while the top of the casing is provided with a pivoted cover 69 so that access may be read1ly.had

to the interior of the casing to effect any necessary repairs to the feed rollers and steam chests.

' In operation, the corrugated strip having a single facing applied thereto, is fed through the corrugatmg machine or from a suitable drum octeel. to the feed rollers? 41 and thence ever the roller 40 and idle roller 70, the roller 40 applying the paste or other adhesive material to the corrugated side of the strip during its passage to the

feed rollers

8 and 9. As the corrugated strip 35 having single facing applied thereto, is fed between the upper and lower series of feed rollers 25 and t), the facing strip 34, by frictional engagement with the strip 35, will be withdrawn from the spool 33 and forced in contact with the adhesive material on the corrugated strip 35, the steam in the feed rollers 2'5 and S) and steam chests 22, serving to dry the adhesive material as said strips are pressed together so as to form a composite strip comprising acorrugated body portion having its opposite sides covered with a facing of paper. As the compositc strip is fed through the front of the machine, the arm 50, by engagement with the lug 58, will intermittently actuate the cutting device to cut or sever said composite strip into predetermined lengths, which strips may be piled on a table or other support 71 designed to receive the same.

By changing the position of the lug 58 on the sprocket chain 30, or by lengthening or shortening the arm 56, the lengths of the strlips of composite paper may be varied at "M If desired, one of the sprocket chains 30 may be used on each side of the machine, and in some cases, the clutch members 62 and 03 may be actuated manually lnstead of.
