REEL ASSEMBLY Filed July 26, 1952 2 Sheets-Sheet 1 March 16, 1954 T, C, SMH-H 2,672,303

REEL ASSEMBLY Filed July 26, 1952 2 Sheets-Sheet 2 tween the side walls Il and I2 of the frame to a k point near the periphery of the reeled portion of the Wire 21, being directed toward approximate tangency with the periphery of said reeled portion.

From its inner end 28a the tube 2B continues through a curved portion 28h passing over the outer edge of the frame side wall H, thence through a substantially arcuate portion 28C adjacent the outer face of said side wall, and thence through a terminal portion 28d consisting of a relatively stiff coiled spring free at its outer end. It will be understood, of course, that the inner end of the spring 28d is suitably secured to the outer extremity of the solid portion of the tube 28, which may be made of suitable metal tubing loosely surrounding the wire 21 and certain distance markers secured thereto as described hereinafter. It will be seen that the terminal portion 28d of the guide tube is directed away from the plane substantially oppositely to the direction in n which the handle 24 projects therefrom.

In the initial coiling of the wire 21 on the spool I6 the inner end of the wire may be threaded inwardly through the guide tube 28 yfrom the open end of the spring portion 28d thereof and secured to the winding drum i3 as previously described. 'Substantially the entire length of the wire may then be reeled in on the spool by rotation of the hand crank by means of its handle 23, until the loop or swivel 3l at the outer end of the wire is drawn up to the open end of the spring portion 28d of the guide tube 2S.

To facilitate the handling of the free end of the wire and the attachment thereof to auxiliary measuring tapes, fixed objects or the like, a snap fastener Sla is preferably linked with the outer ring of the swivel 3|and a leather thong 3Ib is tied to the snap fastener, as shown in Fig. l.

In order to insure proper coiling and retention of the wire on the spool and also to introduce a certain amount of friction opposing overrunning of the spool, particularly following the feeding out of a partial length of the wire, there are provided a number of retaining members in the form of substantially V- shaped spring wires 32, 32, each having its apex secured as by welding, soldering, or other suitable means to one of the spacing members I3' of the reel frame and having its divergent free ends extending toward the axis of rotation of the spool and into the space between the side flanges thereof, preferably bearing resiliently against the inner faces of the said flanges.

Further and variable friction opposing rotation of the spool during unreeling and measuring operations is provided by a brake member in the form of a block 33 engaging the peripheries of the side flanges l1, I8 of the spool, as best shown in Fig. 4. This brake member may suitably be made of wood, fiber, rubber, or other material appropriate for frictional braking action on the spool flanges, which latter, of course, are ordinarily made of metal. The block 33 is secured to a lever arm 34 pivotally mounted upon one of the spacing members i3 of the reel frame assembly Ctl A tension spring 35 is connected between another one of the spacing members I3 and the lever arm 34 at a point thereon farther from its pivotal mounting than the mounting of the block 33 thereon, the spring conveniently extending through an opening 24h through the inner end portion 24a of the handle 2d. Thus in the position shown, the brake member 33 is held resiliently against the peripheries of the spool flanges I1, I8 by the action of the spring 35 and provides frictional resistance against rotation of the spool. The resulting braking effect may, however, be varied over a wide range, or eliminated altogether, by manipulation of the free end portion 32a of the lever arm 34, which portion extends into proximity to the manually engageable portion of the handle 2li.

The employment of the wire for measuring operations is provided for by the securing of distance markers 35, 38, best shown in Figs. 8 and 9, at suitable increments of length along the wire 21, such, for example, as every twenty-five feet. These markers are of sleeve form surrounding the wire 21 and are securely fixed thereto by any suitable means such as rolling, crimping, welding, or the like. The use of a sleeve rolling tool such as is commonly used for connecting abutting ends of telephone wires has been found very effective for securing the markers on the measuring wire with ample tightness to insure against accidental displacement.

The marker members are preferably made of relatively thin metal tubing, such as capillary tubing, of suiicient inside diameter to permit their being slid freely along the wire to the proper locations before being xed in place. Thus they add little bulk to the wire when it is coiled up on the reel and do not interfere with the movement of the wire through the guide tube 28. which is of sufficient internal diameter to permit the marker members to pass therethrough without binding. The movement of the marker members through the guide tube or when in contact with obstructions encountered in the use of the wire for measuring purposes is further facilitated by making the said members with tapered ends 36a, 36a.

The distance measurement from a predetermined ypoint on a particular marker 36 to a predetermined point adjacent the free end of the measuring wire 21, such as the inside of the outer loop of the snap fastener 3 I a, is preferably shown by a specific code marking on the marker, as in-f dicated in Figs. 8 and 9 in the form of i grooves or indentations 36h, 36h.

The entire length of the wire 21 is preferably covered with a suitable protective and insulating coating to afford protection of the wire against rust or other corrosion and against damage by abrasion, and likewise to afford protection against accidents which might otherwiseresult from contact of the wire with live electric wires. Such a coating may be made of a tough plastic insulating material, such as neoprene, polyethylene or vinyl plastics, etc., on the order of two to live thousandths of an inch thick.

Referring now to the mode of operation and use of the device embodying the invention, it will be appreciated that the wire 21 is very resilient and of course tends to spring out of coiled condition unless restrained. The guide tube 23 serves an important function in restraining the wire against undue, displacement in the portion immediately beyond the portion which is coiled upon the spooll, by introducing a substantial Nevertheless? `the tlr'uughl-theftubeliypullingLon-itsouterfendiane 'mam-be; retracted'throug'hf-the tube-withflike easel byif'means ofcthevha'nd crank" as v-preeiciusly;v deze scribed;A

The use of the measuring wire is not limited to measurements coinciding with the lengths indicated by the distance markers 36, 36.
