' Wisconsin fimilication February 1, 1946,"S'eria1 NoJGELHM vl EDhis invention-relates to: improvements in name for level winding devices and "method of .manu- 'facturing the same.
IItiis 'quite common on drose reels "OIVGfihBl' -winding :drums to include .level Winding :mechanism. 'This mechanism usually includes a'shaft driven from the same source as the drum andihaving cam projections thereon. Theswprdjedtionsfiomn crossing rigl'it and left' hand 3helica3l grooves for guiding a cam follower which projects irom th'e line or hose guide. Inasmuch as drumsanwreels vary in wi'dth fordifferenttypes of usesfiit is, of course, necessary ito provide a. cam of proper length for each width. "in the past it haS been common zpractice to either cast 'the cam projections (onto the s'ha ft, entailing the provision of a special casting for each Wvidth o'fidrumwr to'mill aT-"he'lical groove -to produoe the required cam action. The ila'tter procedure entailed a special machine setup ffor each width of :drum.
lit is a general object of "the present iinvention to provide a method of manufacturing cams for level winding devices wherein like cam-"forming sleeves are assembled =on 'a shaft to provide "a suitable cam of .anysselected length.
A *iurther'object of the invention is to provide an improved methodas 'above described, wherein the cams are formed from "three types of @ieces: a 'core shaft piece which is :squareor hexagonal in cross-section; anend'sleevepieee, and'an intermediate s'leeve piece.
further 'ob1iect o'f-the invention is to provide an improved mthodzas=above described, wherein the end sleeve pieces and intermediate s'leeve pieces are preferably -'die-oastings which are 180 designed *as to readily pull -'ou't --'of die, and which are also so designed as t'o cooperate'with like pieces to form riglit andleft hand helieal crossing grooves'when a "plurality of said FSIBSVGS areessembledon the core *haTt.

Slidably assembled on the core shaft are spaced and'opposed .errdssleeves M eachhavingone cam forming end, and :a plurzality of intermediate sleeves :20, each having two icam Eforming ends. All of the intermediate sleeves r20 are identical and are preferably die-mastirom'the sarmevdie.

Theend sleeves are predictably die-castings ifommed :from the-same die.
sReferring :now moze -rpa'i'ticularly :to 2, v 6, 772111158, each -end Sleevelhasan rhexagonal bore 25 :extending thercthmugh. This hexagon-a1 shapei-isausedwwhemthe eoneysha'ft :tfihasthe-hexis squared, then there will be a square bore in the end sleeves in lieu of the bore or, if the shaft I6 is splined, then the bore 25 will be correspondingly formed to cooperate with said spines. The cylindrical extension 23 at one end of each end sleeve is formed with a transverse hole 21 for receiving the pin 24. The reduced diameter extension 23 is, however, not essential as the sleeve may be of uniform diameter throughout the major portion of its length, if desired.
At the opposite end of each end sleeve there is a short extension 28, of reduced diameter, which is cut off at an oblique angle as at 29. The end of the main portion of the sleeve is cut off along a helical line with the helix extending in one direction half way around the circumference as indicated at the shoulder 30, and in a reverse direction for the other half of the circumference, as indicated at the shoulder 3|. The extension 28 forms a part of the base for helical grooves when the parts are in final assembled position, and the cut-off shoulder portions 30 and 3! form the sides of the helical grooves.
An intermediate sleeve piece is illustrated in Figs. 3, 4 and 5. Each of these pieces is generally triangular in the side elevational view of Fig. 3. Each member is formed with a suitable core receiving bore such as the hexagonal bore 32, for receiving the hexagonal core shaft 15. Projecting from one end of the sleeve is an extension 33 and from the opposite end,an extension 34. These extensions have the same diameter as each other but are of reduced diameterwith respect to the intermediate portion of the sleeve. The end 33 is cut off obliquely as at 35 and the end 34 is cut off on the same angle in a reverse direction as at 36. It is apparent that the angle 19 formed between the cut-off 36 and the transverse plane a is equal to the angle 0 formed by the cut-off 35 with said plane a. The angles 1) and c are also equal to the angle d of the end sleeve as is shown in Fig. 6. The cut-offs approximately meet at an apex 31. The intermediate portion of the sleeve is of greater diameter. One end is out along a helical line 38 which extends nearly half way around the circumference from the peak 38 and on a reverse helical line 39 which extends from the peak 38' for nearly the other half of the circumference. At the other end of the sleeve are similar but reversely extending helical cuts 40 and M. The shoulders formed by the cuts 38 and 40 meet at a point as at 42, and the shoulders formed by the cuts 39 and M meet at a point as at 43. The points 42 and 43 terminate short of meeting one another as is clear from Fig. 4 to provide a cross-over space for the crossing helical grooves.
The cut-01f ends 35 and 36 which form equal angles b and c, as well as the cut--ofi' end 29 which forms the angle d, equal to the angles 1) or 0, will match each other when adjacent pieces in reversed positions are assembled on the core shaftas is clear from Figs. 1 and 2. For example, the
extension portion 28 of the end sleeve of Fig. 2
complements the extension portion 34 of the adjacent intermediate sleeve piece to form a complete base for a portion of a helical groove. These extensions 23 and 34 also serve to space the helical shoulders 30 and Ml, and Hand 4| a proper distance apart. The shoulders 3!! and 49 provide part of a helical groove extendin in one direction, and the shoulders 3i and M on the opposite side (which are hidden in Fig. 2), form part of a helical groove extending in a reverse direction and form a continuation of the helicalsgroove which:
.4 is shown in Fig. 2, and which is formed between the shoulders 38 and 4|.
The slidable guide 43 on the hose reel is adapted to guide a length of hose M as it is being wound on the reel [0. The guide is formed with a cam follower which projects inwardly from the location and which coacts with the cam grooves in the usual manner for level winding devices.
It is apparent from the above that the prior method of casting a special level winding cam for each width of reel or drum is no longer necessary, and that any width of cam member may be quickly formed from a piece of the shafting l6, two end pieces [8, and a selected number of intermediate pieces 20, depending upon the final length desired. The pieces I 8 and 20 may be formed inexpensively by a die-casting method with the use of only two dies. The core shaft may be formed from standard cold rolled shafting of hexagonal cross-section, and all that is required are the simple operations of cutting the shafting off to proper length and milling the ends which are to be journalled.
Various changes and modifications may be made without departing from the spirit of the invention, and all of such changes are contemplated, as may come within the scope of the claims.
