WEB GUIDE Eon- 1=APEE ROLLS.

Application iiled May 4,

land State of New Jersey, have invented a new and useful Improvement in Web Guides for Paper Rolls, as set forth in the following specification. y

It is coiiiinonpractice to coil long strips orwebs of paper into rolls of considerable l size for shipment, and the edgesrof the strips are found to be quite ,.even, having been kept so by means of flanged guide rollers, or by,v` means of flanges upon the mandrel upon which the strips are firstrliis process ,answers very well Where a single winding is made; but when it is'required that the strip be Wound repeatedly back; and forth from one roll to another'at different times and under varying hygrometric conditions, it is found that the vpaper has a tendency to creep one way or the other, and the edge `of the strip will climb the adjacent flange. The result is that in a short time the edges of the strip become frayed and torn, and must be replaced by new strips.

My improvement is designed to correct this difficulty, and it finds its bestand most extensive use in, a form of calculating machine,.asset forth'inthe following descrip# tion; it is alsol well adapted, for use in any relation where strips-of paper are to be repeatedly wound from one mandrel to another, as, yfor example: perforated music rolls; master strips for automatic printing machines; strips. usedintabulating machines, etc.

In the accompanying drawing, I have shown my improvement as applied to the forni of calculating machine, wherein tables of figures or numbers are arranged in printed lines and columns upon the strip or web of paper, which is wound from one mandrel to another so as to present the lines of ligures beneath a Window opening in the cover of the machine, in registry with appropriate indices upon the margin of the window opening; the web guides are designed to accurately guide the web or strip so that the columns of figures will register accurately with the indices.

3 is a'sectioii on line III-III of 4parts throughout the specification and drawing.

The calculating machine for which my' improvement is especially adapted consists of a box-.like case 1, having an inclined cover 2, provided with long slot-like window open-k ings 3; witliiiizthe case is a frame made up of the end plates 4, 5,y `rigidly connected by spacing rods 6, 7,j 8; mandrels 9, 10V are mounted to rotate in bearings in the end plates, being driven by an external knob 11 througha train of gears 12, 13, 14, r15. A.

calculating unit comprises a pair of these inandrels with their driving mechanism as thus briefly described, two of such units being shown in Fig.` 2. Larger machines are constructed with moreunits arranged in a inanner'siinilar to that shown in Fig. 2.

A strip or web of specially prepared paper is attached at one end to one of the inandrels, as 9, thence `it is carried over a pair of guide rollers 17, 18, whichare locatedin bearings in the end plates l, 5, and 'contiguous lto one of the windows 3, in order that the lines of figures on the strip may be exposed thereat; thence the strip .y 16 is carried be iieatli the mandrel 9 and up over a secondV pair of guide rollers 19, 20, just beneath another of the windows 3, thence down to and around the other mandrel 10, to which the end ofthe strip is connected. The construction and operation is such that as the knob 11 is turned, the strip 16 is drajvn from one mandrel to the otherand the lines of figures upon both sides lof the strip are improvementcomprises a pair ot the spacing rods 6. 7 between adjusting nuts 23, 24 thereon. The guides are located im mediately above and closely contiguous to the peripheries of the mandrels9, i0, so that their rounded faces 22 may contact with the edges of the strip 16 as it is Woundupon or from the mandrels. YThe guides may be adjusted along the rods 6, 7, so as to adjust the running of the strip 16 with the columns of figures thereon in accurate registry with the indices upon the Window margins, and thus overcome the tendency of the strip to run out of true. The use of the guides as described has overcome an* other very serious dih'iculty-that of fraying and tearing` the' edges of the strip when anges upon the mandrels `vere used, as Well as other types of guides. While very sim ple in construction Vand operation, yet that .Y very simplicity is by no means commensurate Withthe results accomplished.

As above indicated, the improvement is useful in other relations Where the accurate laying of strips of paper or of any 2l, 22, apertured at their ends andl Ymounted upon the screw-threaded ends of YLacrime peripheries of both of said mandrels and at right angles to their axes.

2. In a guide mechanism for Vweb paper rolls, the combination of a pair of mandrelshaving means for Winding a strip of paper from one mandrel to the other and vice versa, VVWith means for guiding said strip comprising a pair of metal bars l0- cated closely contiguous to the peripheries of said 1n andrels and at right angles to their axes, and means foradjusting saidV bars in a direction parallel to said axes.

3. In a guide mechanism for paper rolls, the combination of a pair of rotating mandrels having means for Winding a strip of paper from one mandrel to the other,

with a pair or" guiding bars rigidly `supported immediately adjacent to the periphcries of said mandrels, and means for adf justably Yspacing said bars apart for contact Withrthe edges of said strip ofpaper.

'4. In a guide mechanism for paper rolls, the combination of apair of mandrels With means for guiding a strip of paper from one of'said mandrels to the other comprising a pair of guide bars located immediately above said mandrels and spaced apartifor contact with the respective edges of said strip of paper, and meansrfor laterally adjusting each of said bars in a direction parallel with the axes of said mandrels.

5. In a guide for paper rolls, the combination of a frame comprising a pair of end plates, spacing rods rigidly connecting said plates together, a pair of mandrels mounted in said end plates, means for rotatiing said mandrels tonwind a strip of paper from one to the other, with means for accurately guiding said strip of paper, comprising a pair of guide bars mounted upon said spacing rods and located closely contiguous to the Vperipheries of'said mandreis, and means 'or adjusting said bars along said rods into contact With'Y the respective edges of said strip of paper, whereby to accurately y guide the same as it Yis Wound from one mandrel dto the other and vice versa.
