GLENN S. WILLIAMSON, OF NEW YORK, N. Y.

MECHANISM FOR UNITING PRINTING-PRESS WEBS AND THE LIKE.

'- To all whom it may concern:

Be it known that I, GLENN S. WILmaM- soN, a citizen-of the United States, resid ng at New 'York, in the county of New York paper and the like, and to means for carrying out such method.

The invention may in practice be advantageously employed in numerous instances.

As an example, it has been used to great advantage in uniting or piecing together the stubs of printing press rolls to form a new roll, which has enabled utilization of material previously treated as waste.

The Various objects and advantages of the invention will hereinafter appear.

The accompanying drawings comprise schematic views exemplifying the method and certain of the preferred elements for carrying out said method and also views of a mechanical embodiment of such elements. The means for carrying out the method may,

ofcourse, be embodied in other forms and may be provided with various additional advantageous features, such as those disclosed in an application of Gustave B. Reisbach, Serial No. 831,063, filed April 1-0. 1914.

Specification of Letters Patent.

The method will be explained in connection with Fig. 1, which shows two pieces of material. A and B, for brevity termed webs. It consists in first overlapping the ends of the two webs, preferably with their margins a and b in alinement. l/Vhen so Patent-ed Feb. 27, 1917. 7

Application filed April 4, 1914. Serial No. 829,571.

overlapped the webs .are preferably firmly clamped to their support, as by means hereinafter set forth, and then severed on a common line m g, preferably obliquely disposed or on a, bias with respect to the webs. Thereupon-the severed end a of the upper web is displaced, leaving thecut edgesof both webs exposed and in abutting relation. The webs are then ready tobe united and this is preferably accomplished by applying along the line 0cy a sealing strip 0 to overlap and adhere to both webs. Of course, the webs might be united in other ways than by the aforesaid overlapping sealing strip, but said strip ispreferred. In this connection, also, it is preferred to employ for said strip a very thin rubber coated tissue paper or the like andto heat the same during application to effect adhesion thereof to the webs.

The aforesaid operations are'in practice preferably carried on simultaneously. That is to say the waste end of the upper web is displaced as the cutting progresses and the sealing strip is applied as the displacement of the waste material progresses.

By the method described the two webs oiother materials are securely united and the o1nt between the same is smooth and \Vlll In consequence, the webs when united may be run through a press or other mechanism with little resistance. at the line of connection and this resistance, as well as the strain on the joint, may be materially reduced by uniting the webs on an oblique line, as'aforesaid.

Referring now to Fig. 2, the same shows a work supporting table 1 provided on its upper face with a groove 2 to receive the blade of the cutter, hereinafter specified. The table has overlapped thereon, across the groove 2, the ends of two web rolls A and B. Clamping strips 3 are shown to clamp the overlapped ends against the table on opposite sides of the groove.

Fig. 2 also shows schematically a rotary cutter 4, a wastedisplacing plow' 5, a reel of sealing strip 6, and a heated pressure device 7 to apply the sealingstrip to the webs. g In practice, the aforesaid elements are preferably embodied in a unitary device mounted for movement across the table, as hereinafter set forth, and adapted to perform their respective functions automatically as the movement of said device progresses.

' Referring now to Fig. 3, the apparatus as illustrated therein includes a table 1, as already described,a traveling device 10 carrying the abovespe'cified and other movable elements and a frame 11 extending across the table to support the traveling device 10 and also to carry the clamping strips 30f Fig: 2.

' The frame 11 is preferably pivoted to the table 1 at one side thereof, as at 12, and counter-weighted whereby it may be readily raised to clear the table for arrangement of the webs thereon and lowered to clamp the webs against the table. The device 10 travels back and forth'longitudinally of the frame 11 and is moved into andout of operative relation with the work by movement of said frame. As shown, the device 10 is so arranged on the frame as to move to the right for cutting and sealing the webs when the frame is lowered to the table and after the cutting and sealing operation the frame is 3 raised and the device 10 returned to the position shown.

First specifically considering the traveling device 10, the same is more fully illustrated in Figs. 4, 5 and 6. As best shown in Fig.

5 5, it includes an open supporting frame 15 provided at the right hand end with transverse shaft'16 carrying supporting rollers 17 and 18 and at its opposite end with a transverse shaft 19 carrying supporting rollers 20 and 21. This frame 15 carries the aforesaid elements of Fig. 2 in the following relative positionsbest illustrated in Figs. 4 and 6. The rotary cutter 4 and plow 5 are arranged at the base of said frame to- ,45 -\vard the rear end thereof. the former being shown in Fig; 4 and both being shown 'in Fig. 6. The pressure device 7 is connected to the rear of the frame while the roll of.

sealing strip is carried by a reel 22 on the upper sideof'the frame and is fed by suitable mechanism, hereinafter described, to a point between the cutter and the pressure device 7. a I

The traveling frame also carries a knife 23 for severing the sealing strip, said knife being interposed between the previously mentioned feeding mechanism and the pressure device 7. Still further, the frame carries a motor 24 for propelling the same along the aforesaid table frame 11 and by this propulsion supplying power to operate -the rotary cutter 4 and aforesaid feeding mechanism.

More specifically considering the rotary cutter 4 the same is mounted upon a spindle 25 and is driven through pinions 26, 27 and 1 28 from a pinion 29; the latter, as best illusstrip, which is also driven from the shaft 30, will now be described. It includes a suitable guide 32 having spaced walls to re ceive the sealing strip therebetween and openings therethrough to receive gripping and feeding rolls for said strip. Oneset of rolls is arranged contiguous to the receivin g end of the guide and includes a fixed roll 33 and a yielding roll 34, the latter being mounted upon a short lever 35 biased by a spring 36 to press said roll 34 against said The other set includes similar rolls 37 and 38 located adjacent to the delivery end of said guide. 'Thus the rolls 33 and 34 .grip the sealing strip as it enters the guide and feed the same to the rolls 37 and 38, which in turn feed the strip through the delivery end of the guide. The rolls 33 and 37 are power operated in the following manner: The roll 33 has fixed thereto a pinion 39, connected through a pinion 40, to a pinion 41 on the aforesaid shaft 30. This provides for positive drive of the roll33 which in turn drives the roll 37 through a train of pinions 42 including a pinion fixed to said roll 37. Thus, like the rotary cutter, the feeding mechanism is set in operation upon movement of the traveling device. However, it is only desired to have the feeding mechanism operate during movement of the traveling device in one direction and accordingly means are preferably provided for rendering the feeding mechanism inoperative during reverse movement of the traveling device. The means illustrated for this purpose comprises a roller clutch 44' interposed between thepinion 41 and the shaft 30, said clutch operating in a well-known manner to connect and release said parts according to the direction of rotation of said shaft. It should, of course, be understood that variousother means might be employed for the aforesaid purpose.

Next considering the knife for severing the sealing strip. the same is illustrated as reciprocably working in a block 45 abutting the end'.of the guide of the feeding mechanism and having a passage 46 therethrough forming in effect a continuation of said guide. The knife may, in practice. be operated in any preferred way, but as illus:

trated the same is connected, by a rod 47 to the plunger of a solenoid 48, suitably mounted on the traveling device.

to sever the sealing strip while a spring device 49 is provided to retract the solenoid plunger and thus raise the knife when the diately after the same emerges from said block. -This pressure device is preferably detachably secured to the traveling 'dei ice and provided with a more or less free connection therewith, whereby its full force w1ll be exerted upon the sealing strip and webs;.'

To this end the same is preferably provided with laterally projecting pins 50 and 51 fitting into notches52 and 53 respectively in opposite sides of the traveling frame. Also, in practice, the pressure device is preferably electrically heated as by a coil 54 diagram- -maticallyillustrated in Fig. 4.

As will now be apparent when the traveling device is moved forwardly the rotary cutter will be set in operation and the feeding mechanism will likewise be set in operation to unreel thesealing strip and feed the same to a point just in advance of the pressure device which during continued movement rides over said strip, heating and pressing the same against the webs. Then to sever the sealing strip after completion of the sealing operation it is merely necessary to energize the solenoid 48 to operate the knife 22 as aforesaid. 4

The propulsion of the traveling device to effect the aforesaid operations is accomplished by the motor as follows: Referring to Fig. 5 the motor has fixed to its armature shaft a pinion 55 which meshes with a gear 56 fixed to a shaft 57 on which shaft is also fixed a pinion 58 meshing with a gear 58" fixed to the roller supportingshaft- 19. Th shaft 19 in turn has fixed to one end thereof a pinion 59 which, like the pinion 31, is adapted to mesh with a stationary. rack on the table frame. Thus when the, motor is set in operation it drives the pinion 59 through the gearing aforesaid to positively propel the traveling device along the table frame at'the desired speed, it being understood that the intermediate gearing lnaybe designed for any preferred speed and that the motor is reversible to propel the device in-either direction.

Adverting now to the frame'll which supports the traveling device, the same ispreferably constructed as follows: As best illustrated in Figs. 8 and 7-, it is provided with two parallel. bars 60 and 61 disposed on opposite sides of the slot2 in the table. These bars, as shown in Fig. 7, are of channel iron construction and are provided on The solenoid 48 when energized forces the knife downwardly their upper sides with rails 62 and 63 for the supporting rollers of the traveling device. Also, the bar 60 is provided on its upper side with a rack bar 64 furnishing the aforesaid fixed rack'for the pinions 31 and 59,

of the traveling device. Thus is provided a fixed path of movement for the traveling device coincident with the slot'2 in the table which slot as above stated is provided to receive the rotary cutter 4'of said traveling device.

The frame 11 also, as previously stated, carries the clamping strips 3 of Fig. 2 and as shown in Fig. 7 these strips are suitably attached to the undersides of the bars 60 and 61. In practice, these strips preferably comprise lengths of rubber tubing, this material being selected for its yielding and gripping qualities. However, other material might be used therefor, if desired. Also, in practice, the clamping strips are preferably arranged in. as closeproximity to the groove 2 as. the construction of the traveling device will permit so as to grip the webs as near as possible to the line of severance and thereby reduce the liability of the cutter snagging the edges of the webs. For this, the bar 60 is shown as provided with'an inward extension 65 for car-' the point of the plow 5 on the traveling devic therebetween. In practice, such marginal spacing of the webs may be accomplished by various means, as, for example, that illustrated in Fig. 8'. In this figure the table is illustrated as provided with a finger 67 suitably arranged between the bars of the table frame 11 so .that one web may be passed beneath and the other over the same as indicated by dotted lines. For simplicity of illustration the finger 67 is shown in fixed position, although it should be understood that the same might be pivoted, and provided with a suitable operating member whereby it may be raised similarly to the mechanism for electrical control in any one I an insulating block 69 fixed to the bar 60 of of a number of different ways. For such control the circuit connections for the elec tric parts on the movable carriage may be readily provided for by the means illustrated in Fig. 7. This means comprises a plurality of contact strips '68 mounted on the table frame, and cooperating contact brushes 70 mounted upon an insulating block Tl adapted to be secured to the traveling device. It is, of course, to be understood that the number of contact strips and brushes may be varied, as desired.

One very advantageous form of control for the mechanism described is disclosed in the Reisbach application, aforesaid.
