V CABLE-srooLINe DEVICE.
\ Application mea December 23, i926. serial m4156322..
e This invention relates to new and useful improvements in devicesforuse in the spoolmg'or unspooling of cable `upon or from a cable spool, and has forits primary object to provide a machine wherein the spool may be rapidly associated with or removed from thek 4machine, and this without requiring the entire dismantling of the machine, and no unusual skilled labor upon the part of the operator. l y
A further and most important object isto provide means whereby the'tension of the .cable may be regulated during the removal of the cable from the spool.
Yet another Object is to provide a machine of this character tha-tis extremely novel, simple, and efficient in operation., the same embodying but few parts and these so core lated as to reduce the possibility of disarrangement to a minimum.
With the foregoing and other objects in View as the nature of the invention will be better understood, thel same comprises the novel form, combina-tion and arrangement o f parts hereinafter morev fully described, shown in the accompanying drawings and claimed.
In the accompanying drawings wherein like numerals indicate corresponding parts throughout the several views: Figure 1 is a sideelevation of a cable spooling machine constructed in accordance with the present invention.
Figure 2 is an end elevation thereof. Figure 3-is an enlarged fragmentary elevat-ion of the braking mechanism whereby the tension on the cable may be controlled when removing the cable from the spool.
. Figure 4 is a somewhat similar view in longitudinal cross section, and
Y Figure 5 is a perspective of one of the spool engaging cones.
Now having particular reference to the drawings, my novel device consists of al pair the .outer end of avhollow shaft 10, upon the.
inner end of which is disposed a spool engaging cone 11. This cone 11 mav be of any predetermined size and is formed centrally with a horizontal bore 12, the outer end of which is lof enlarged diameter for receiving the inner end of the hollowshaftlO. The eX- j terior surface of this shaftl() at its inner end is horizontallyk channeled as at 18, while the enlarged area of the cone'hore is alsoformed with a horizontal channel 14 registering with the channel 13 inthe shaft 10 so as to receive a locking key 15.
Mounted within the end of the standard 5 is a similar hollow shaft 16 to the inner end of which is xed a spool enga-ging cone 17 identical in construction toV bearing 7 at theupper the conell and secured tothe shaft 16ina manner similar to the securing of said cone 11 to its shaft 10.
Each'of the cones is formed witlrlongit'u-l dinally extending spaced ribs 18, somewhat sharpened at their-'edges for obviouslyv cuttin-g into the material forming the cable spool A disclosed in dotted lines in Figure 1.
The spool engagingcones 11 and 17 are spool between said cones, it is necessary that one of the standards 5 or 6 be moved to such a position as to permit the spool to be arranged upon one ofthe cones. i This standard is then positioned so that its cone will engage within the opposite end of the spool so as to firmly secure the same between the cones. j
After the spool A has'been properly aryranged between the cones 11 and 17 there is Y disposed through the shafts 10V and 16 an elongated bar 19 headed at one end as at 20 and threaded at its opposite end as at 21, see Figures 1 and 4. After -this har has been extended through the hollow shaft, nuts 22 are threaded upon the threaded end thereof so as to prevent separation ofthe standards 5 and 6 and to securely lock in horizontal align-V ment thccone carrying shafts 10 and 16.
Keyed to theshaft 1() intermediate the arms 8 8 ofthe standard 6 is a Abrake drum 23 ci'rcumferentiallyflanged at itsopposite edges Vas at 24.--24 Arranged substantially enti rcly around this drum 23. is a metallic brake band y25 .provided on its innerface with a.
brake lining 26. One en'd of the band 25 is rolled Vto form a bearing 27 for a pin 28,
the ends of which extend through said bearsecured at its lopposite ends in registering openings provided. therefor in the `lower end ing and to Vwhich are attached eye bolts 29-29, the eyes thereof encircling a pin 30 101" 1 Apinfl/l disposedf The inner endqo'f` this i Y`hand lever 36 is of enlarged diameter as at posite end of this band` is also rolled to form a bearing 31 Within which is a pin 32, the center of this bearing being;r slotted so as to perinit of the pivotal attachment of the eyed endB?) of an elongated pin 34 to saidlpin 32; L Rotatably mounted upon the pin between the eye bolts 29-29 is `a block 35lto Whiehis I secured an, outwardly extending hand lever- 36 of circular shape in crose `sectionand "over which the eyed outer end`37 ofthe elongated 3S, seeFipjure 2 so 'as to limit the' inward movement of the pin lthereon. ',Obviously by forcing downwardly upon the le-ver- 36,v
the band 25 is tightened upon the drum 23 for bralingthe rotation of" the shaft 1() and 16 as Well :alstlie spool Al V`Ae`sociated with the shaftlris alsuitablesprocket Wheel`38 over which may be trained an endless driven sprocket chain so as t'o facilitate the rotation of the spool A during the y winding of cable thereon.
i In view lofthe foregoingdescription when considered in'coniunction with the` a'cconr Y ,panying drawingsit will 'at once be apparent VWell adapted for all thepurposes heretofore 30 that I have "provided a highly novel, simple' andellicient cable spooling machine thatis designated, even though I 'have herein shown A and fdescribed the invention as consisting of certain detail structural elements, it is never Vthelese to be understood that nnnor changes` ofthe respective cone being provided with cochannels to`'poSiti`vely lockl the conesren the operating channels, a` key insertable ins-aide vinner endso'f `the shaft, longitudinall, s eii-V 4tendingr ribs foi-med onthe outer face o each cone for forcible engagement with 'tl1e.bore" of the spool` at the respective" ends tliereoffjj Y an elongated bolt extendingV longitudinally through the hollow shafts and the cones for interconnecting the Standards, and a driving member arranged on oneof the hollow shafts.
