Specification of Letters Patent.

Patented April 24, 1906.

Application filed May 9,1903. Serial No- 156,898.

To t whom it may concern;

Be it known that 1- JOHN C. F. BALZE, a citizen of the United @tates, residing at New 1 York, county of New York, and State. of New York, have invented certain. new and use-\ ful Improvements in lVeb-tiluides, l'ully described and' represented in the following specification and the accompanying drawings, l forming apart of the same.

This invention relates to certain improve ments in web-guides.

In machines in which running webs are eml ployed it is customary to interpose in the ath of the web guides the purpose of which is to change the path of the web.

One form of such guides is what is known as the angle-bar, which is ordinarily set at an angle of about forty-tire degrees to the bars being also set at an angle of about fortylive degrees to the path of the web, the purpose of this guide being to shii'tthe web laterally without changing its general direction of movement. in this construction the amount of lateral shilt'is varied by shifting i one of the bars with relation to the other, the parallelism of the bars and their degree of an 1 gularity with respect to the path of the web path of the web and the purpose of which is l i being maintained unchanged. W'ith this construction the minimum of lateral transfer. is equal to the sum of half the diameters of the bars, and the lateral transfer is, iiecissarily always an increase in the same direction. In other ,words, when the bars are as close together as is possible the web is given the smallest amount ol-lateral transfer possible, the entire web being then shil'ted laterally a 1 distance equal to the sum of ball lhc diamctersol' the two bars, and the amount of lateral shift as the distance,hetwcen the bars is varied will increase as the bars are separated.

A third l'orm ol guide which is sometimes a large tubular guide,

employed consists of around which the web is given a complete vi l i i wrap. lhis torm ol' guide must always shlft the weblat erally an amount equal to the width ot the web, and with this form of guide any turther transfer ol the web is eliected by increasmg the size of the bar. l

tion of another constructionof guide embody- These forms of guides have usually had both ends mounted in the machine, the only adjustment of them being eti'ected by moving them into different positions, each )osition ol' the guide, however, being parallel to every other position.

The object of this invention is to produce an improved web-guide which may be given an angular adjustment for the purpose of controlling the movement of a web.

\With this and other objects in view the invention consists in certain constructions and in certain parts, improvements, and. combinations, as will be hereinafter fully described, and then specificallypointed out in the claims hereunto appended.

Referring to the accompanying drawings, Figure 1 is a plan view of a construction embodying the improved form of guide. Fig. 2 is an elevation, partly in section, of the construction shown in Fig. 1. 1

ing the invention. Fig. 4 is a plan view of the constructionshown in Fig. 3. Fig. 5 is a side view, and Fig. (i is a detailsectional view.

The form of guide in which the invention is embodied may be widely varied; but in the preferred construction the guide will consist of two members, as bars, the web being passed iirst around one of the members and then around the other, and this is the form oi guide which has been selected to illustrate the. invention. The construction by which the guide, whatever be its form, is mounted so that it may be given an angular adjustment to change the widthwise position of the traveling web after it leaves the guide may be varied within wide limits; but preferably the members ol the guide will be'mounted a t one eiid',"tlie other end being left free, and preferably it will be such, where a guide coin prising two members is employed, that these members .ina receive a simultaneous iid justiiieiit.

\et'erring more particularly to Figs. 1 and Z, a lollii of guideis shown which is adapted to control the movement ol' two running webs runningindiilerent planes, these guides being arranged so' as to associate the webs. In these figures, 1 indicates a portion of the frame in which the guides are mounted, the frame being provided with inwardly-extending brackets 2 3, which serve to support a Fig. 3 is an eleyavertical rod 4. Mounted on this red is a hub or collar 5, said collar being rovided with bearings 6, said bearings, as s own, extending from each side of the hub and one of them bem arranged above the other. In one of the earings 6 is mounted a guide member 7, and the other bearing 6 is mounted another guide member 8, these members, as

' shown, consisting of cylindrical bars. In the preferred construction and as shown these it will be seen that the upper surface of the bar 7, around which the incoming web first passes, is nearer to the ath of the incoming Web than the upper sur ace of the bar 8. Below the hub 5 is mounted another hub 9, said hub being provided with bearings 10, which extend from each side thereof, one of the bearings being located above the other, and in these bearings are mounted guide members 11 and 12, which are also shown as consisting of cylindrical bars. These members preferably also arcs) arranged that the surface of the bar with which the web first comes in contact is nearer to the path of the incoming web than the surface of the; other bar. The two webs which are controlled by these guides are marked W and W, the web W running over the upper member and the Web W over the lower guide membcr and the guides being set so as to superpose the web W upon the web W.

Inasmuch as the members of each guide are so arranged that the. surface of the memher with which the web first comes in contact is nearerthe path of the incoming web than the surface of the other member, the web can be passed around the upper and lower surface of the upper member of each guide and then around the up er and lower surface of the l 'ower member 0 each guide, a s is shown, for instance, in Figs. 1' and 2.

The angular movement by which the guides control the position of the webs may be effected by any suitable means. As shown, the hub 5 is provided with a segment 13 and the hub 9 with a similar segment 14. Mounted in suitable bearings 15 and 16 in the frame are two short shafts l7 and 18, lheseshafts being provided on their inmer ends with worms 19 and 2H, and on their outer ends with hand-wheels 21 and 22. \Vith this construction it is obvious that the. position of either guide may be shifted in either direction and that this maybe accomplished without interrupting the operation of the machine in which the guides are cl uployed. Furthermore, the position of either web may be adjusted with extreme nicety. For instance, should it be found that either web 1s running member 30.

slightly out of register with the other or if the webs are being delivered to a folder and it be found that the webs are not running with respect to the folder so as to be accuadapted for use where two webs are running side by side in substantially the same plane and where the position of each web is to be shifted in its plane, the webs not being associated. In this construction the frame 1 is provided with vertical brackets 23 and 24, each of these brackets being provided with bearings which serve to support vertical shafts 25 26. The shaft 25 is provided with two bearings 27 28, which are secured to the shaft, the bearing 27 carrying a guide member 29 and the bearing 28 carrying a guide Similarly the shaft 26 has secured to it two bearings 31 3-2, the bearing 31 supporting a guide member 33 and thebearing 32 supporting a guide member 34. Webs W Vii are shown as running in a horizontal plane, the web W taking a downward turn over the guide member 29 and then a turn over the guide member 30, after .which it passes down over a roll-guide. 35, suitably supported in the frame. The web W is also shown as running in a horizontal plane and as taking a downward turn over the member 33 and around the member 34, after which it also passes down over the guide 35.

As in the construction previouslydescribed, the guide members are capacitated to receive a simultaneous swinging adjustment, which may be effected by any suitable means In the construction shown the shaft 25. is provided with a segment 36 and the shaft 26 is provided with a segment 37, these segments being secured to the shafts. Supported in the brackets 23 and 24 is a long shaft 38, having a worm 39 on its end, which meshes with the scgmeht 37. The shaft 38 is provided on its other end with a hand-wheel 40, and

mounted on it in the construction shown is a short tubular shaft 41, provided with a worm 42 and a hand-wheel 43. This worm 42 is in mesh with the segment 36. It will be read. ily understood that by turning either of the hand-wheels the vertical shaft, whiehthe handwheel shaft controls by means of its worm, is given an axial movement. thus swinging the guides.

1n the construction shown the guide which controls the web W is shown as at rigln angles to the web, so that the web runs over it without having its lateral position changed thereby. The guide which controls the web W however, swung at an angle to the path ot travel at the web, so that the position of the web is sliilt,eil,tlie web being caused to travel slightly nearer to the supporting bracket 2; after it leaves the guide than it would were the guide not shifted.

While any of the wcll-known guides may, under certain conditions, be advantageously mounted to receivea swinging adjustment, the term of guide illustrated is especially adaptcd tor the purposcol' the invention, and such swinging guides will be found especially valuable where it is desired to shift the position of the web laterally slightly without changing the general direction of its run, in order. lor instance, to bring it truly into register with another web or to cause it to run truly to a lolding mechanism or to any other mechanism by whichit is to beopcratcd upon. While, as before indicated, the construction by which the swinging adjustment is ell'ectcd may be widely varicd in its character, it is particularly desirable mat the guide be so mounted that the desired adjustment may be given without interfering with the operation ol' the machine as a whole,

\Yhile the constructions illustrated embody the invention in prcl'crrcd terms, it is to be understood that changes and variations may oc made therein without departing from the invention. The invention is not, therelore. to be limited to the spccitic constructions hercinbchire shown and described.
