The ilatchplate. isz'smallerl'inrwidth than the diameter of 1thecspindle; whereby the latch plate mayxbemoyediztothe position shown in dotted lines in Figure ;2 to permit a roll of'perforated:

metallic tape T to ijbesslid over the latch plate and onto :the, spindle- After the::roll of :tape has been mounted ,onithe: spindle, the :outer washer l 4 r isireplacedgand :the ilatchtplateis movedvtc the position'rshown inznill lines Figure 52, whereby A guide and cutting block 20 is secured to the Q base plate near its upper end by'means' of screws 2 I. The guide block extends perpendicularly outward from the base plate and is disposed at an angle to the longitudinal axis of said base plate so that the tape which is being unrolled from the roll T carriedby the spindle Il may be directed and will readily pass over the upper surface 22 of the guide block. A downwardly and rearwardly projecting neck portion 23 is formed integral with the guide block, said neck portion having a width less than the width of the guide block but substantially equal to the width of the thin metallic tape. A substantially rectangular spring friction clip or plate 24, having a pair of opposed downwardly then inwardly turned catches or wings 25 at its lower end, is mounted on the guide block with the wings 25 engaging around the neck portion 23 at the lower end of the block. outwardly extending lugs 26 formed on opposite sides of the lower end of the neck portion 23 of the block provide notches 21 on each side of the neck for receiving the catch wings 25 whereby the spring clip 24 is retained in position on the guide block. The spring clip plate 24 is bent downwardly at an angle along a, line 28 just above thewings 25, whereby the spring plate will engage firmly and resiliently against the upper surface 22 of the guide block and will positively frictionally restrain the tape, which is threaded between said spring clip and the upper surface of the guide block, against undesired movement. The upper end 29 of the spring clip terminates short of the upper edge 30 of the guide and cutting block, whereby the user may readily grasp tape extending beyond the end of the clip in a manner which will be hereinafter described. a

- A pair of spaced vertical slots.33 are provided at the upper end of the base plate I0 for receiving a belt 34 or other supporting means, whereby the reel assembly may be releasably secured to the waist or other parts of the person of the user.

In use, the thin metallic tape is mounted on the spindle ll, in the manner already described, and is threaded over the upper surface22 of the guide block and beneath the spring clip 24, in the manner illustrated in dotted lines in Figure l. The end of the tape will extend beyond the spring clip 24 and may readily be gripped between the finger and thumb of the user to permit unrolling lengths of tape from the roll. When a desired length of tape'has been unreeled and pulled past the guide block, and it is desired to separate that portion of the tape from the remainder on the spool, the user will grip the spring clip 24 to press the-tape downwardly against the upper surface 22 of the guide block and will bend the edge of the free end of the tape downwardly'along the upper edge 30 of the guide block to part the tape along a line deter-' mined by such upper edge of the guide and cutting block, in the manner'illustrated in Figure 5.

The upper edge of the guide block thus servesas a cutting edge for parting the tape at desired points. The exposed end of the tape extending beyond the upper end of the spring clip plate on the upper surface of the guide block may then be engaged by the thumb or finger of the user to witlhdraw an additional length of tape from the rol When the tape is used for sealing or closing the joint between adjacent sections of wall board at corners or angles in the wall, the tape is folded upon itself along its longitudinal axis to form the tape in an angular shaped strip. This operation is called crimping the tape, and has heretofore been done manually by one operator installing the tape. Manual crimping or folding of the tape is a slow process and does not always produce a uniform angular or crimped strip, with the result that the joint closure may be irregular.

In order to facilitate the crimping or folding of the thin perforated metallic strip along its longitudinal axis, the crimping device illustrated in Figures 6 and 7 has been provided for automatically folding or crimping the tape as the same is withdrawn .from the roll carried on the spindle of the reel and crimping device. An elongate flat crimper arm 35 is pivotally securedby means of a screw 36 to the lower end of the neck portion 23 of the guide block at a point near the outer edge thereof, as clearly shown in Figures 1 and 2, but the arm may readily be swung upwardly to the position illustrated in Figures 6 and '7 when it is desired to crimp or fold the tape along its longitudinal axis. The free end of the crimper arm 35 has an elongate crimping slot 37 formed therein, and the slot is so positioned that it extends parallel to the upper surface 22 of the guide block when the arm is raised to crimping position. The length of the slot is such that it terminates at' a point substantially centrally of the neck portion of the guide block.

When the user of the device desires to crimp or fold the tape along its longitudinal axis, the free' end of the tape is withdrawn from between the spring clip plate 24 and the upper surface of the guide block, and is bent or crimped along its longitudinal axis by hand for a short distance. The bent or crimped portion of the tape is then inserted in the slot 31 of the crimper arm with the bend at the inner end of the slot, and is then threaded between the spring clip plate and the upper surface of the guide block, as clearly shown in Figures 6 and 7. The user then grips'the free end 48 of the tape and pulls the same upwardly, whereupon the tape withdrawn from the roll is automatically bent or folded or crimped along its longitudinal axis as it is drawn through the crimper slot. The inner end of the crimper slot, being located substantially centrally of theneck portion of the guide block and centrally of the flat tape strip, will positively cause the flat tape to be bent upon itself along its central longitudinal axis as the tape is withdrawn from the roll carried on'the spindle of the reel, When the desired length of folded or crimped tape has been withdrawn, it may be parted or torn alongthe upper edge 30 of the guide block in the manner already described to cut off the desired length or portion thereof. The exposed end of the crimped or folded tape remaining in the device and etxending beyond the upper end of the spring clip plate on the upper surface of the guide block may then be engaged by the thumb or finger of the user to withdraw an additional length of,

crimped or folded tape from the reel.

5- Afterthe desired amount .ofcrimped or folded atom-so;

tape has. been used. and i i is desired: to use the.

flattape again, the operator may withdraw the. folded or-crimped portion of the tape frombetween the springclip plate and the guide block and unfold the short crimped or folded section; 'IEhe unfolded flattened end of the tape may then bereinserted or theraded between .the spring clip plate and the upper surface of the guide block, whereuponthe fiat tape again ready, for me.

From the foregoing, it will be seen that an improved tape dispensingreel and angle crimper at any desired point to separate portions of the tape from the roll thereof as needed.

It will particularly be noted that the tape reel and dispensing device is provided with means for automatically crimping or folding the tape along its longitudinal axis as the tape is withdrawn from the roll carried by the reel, whereby the tape is automatically formed for. fitting ,corners or angles .as it is. withdrawn. Furthermore, it

will be seen that thetape reel is provided with means for holding the roll of tape against undesired rotation, whereby the roll does not become loose and interfere with movements of the user.

Also, it is apparent that the tape reel issimple.

in structure. and economical to manufacture, compact in form, may be worn on the person of the user and will not interfere with the normal movements of the user.

The foregoing description of the invention is explanatory only, and changes in the details of the construction illustrated may be made by those skilled in the art, within the scope of the ap-' pended claims, without departing from thespirit of the invention.
