I N VENTOR.

Patented Jan. 11, 1944 UNITED STATES PATENT OFFICE MEANS FOR SHORTENING THE EFFECTIVE LENGTH OF LINES.V OR CORDS' Thisv invention relates to means for pulling on a line or cord to tighten it. Embodiments of the invention may be employed for purposes such as tightening clothes lines,- tent lines, and guy lines.

The tendency of the. line when tightened is .to cause the device to rotate in a. reverse direction which would slacken the line. This is prevented, however, by suitable holding means which forms part of the device.

In one form of the invention the` device may be used on a stationary clothesline or onl a pulley clothes line. In the latter case it may be demountably attached to the clothes. carrying reach oi the line and travels therewith.

In each of two other forms of the invention the device serves not only as a tightener but also as a means to prevent spreading of the various reaches of the pulley line when thelatter is loaded with articles of clothes.

Other features and advantages will hereinafter appear.

Similar reference characters represent similar parts throughout the speciiication.

The form of device or tightener 29 illustrated in Figs. 1 and 2' to 5, inclusive, ccmprisesanarm or body part 33 having at one end a winding means 3| including a' reel 32. A slot or space3-3 divides the reel 32 `into two`

members

34 and 35. The reel also includes two notches 31l and 39.

The tightener 29 is detachably connectable to the-lower reach 40-of a pulley clothesline 4l, Fig. 1. The clothes linev also includes. an upper reach 40', the two reaches forming; an elongated loop supported atopposite. ends by suitablefpulleys.

To attach the tightener: 29 to the. line reach 40 it is placed as in Figs. 2 and 3 with the reach lll` in the slot 33. The tightener is subsequently rotated sidewise inthe direction of the arrow in Fig. 2 so that the

members

34 and 35 grip the line 40.. As the rotation of the-tightener continues the. line portion 40 enters thenotches 31 and 39 and Windsl around the reel 32 which forms a base for the

members

34 and 35. In the event that the line is not suiliciently tight when the device has been rotated through 270 degrees the. latter may be rotated still further until the line. is sufficiently tight. Due to the taut condition of the line it tends to reversely rotate the tightenel 29. This is prevented, however, by suitable holding means 45 caused to engagethe line.

The tightener 29 may be composedjof'wood or any other suitable material. When, however,A a kind or wood, is used which is not of great strength, the

members

34 and 35 may be reinforced, against breakage at the base 44', byl screws 441:, Fig. 3.

The holdingl means comprises two grooves 4:5 formed in` opposite faces of an extension- 41 on the body part 3l!V into' either one of which a portion of the line may be inserted. A tongue 4B projectsfrom the-extension 41 towards the. reel Winding device 3l andassists in keeping the line in the grooves 4.6. To insert the line. into the groove the tight'ener is rotated .until the extension is slightlypast vthe reach 40 so that the said reach may be moved pastsaidA tongue towards the body part and then into alignmentwith the slot 4t. The tighteningy device is then permitted to re VerseIy; rotateslightly until the line reach has entered .said groove, 46. If the tongue 43 is made long enough it may serve alone,v without the grooves 46, to hold the reach 4 0 on the extension 41 since itforms, with. the body partor handle 3B, a. slot extendingtowards and having its open end nearest the reel 3|` so thatv the reach 40 may readily be placed into said slot.' When, however, the grooves 46 are used with the vtongue 48 it may be shorter depending upon the' depth ofj the grooves 41.

Since the tendency of the line 40y is to reversely rotatethe tighteningv device 29 the line must be inserted intothe groove in the face of the device` opposite to that at which the line portion leaves the winding means 3|. Thus the tendency of the line to reversely rotate the tightening device 2t causes the extension 4l thereof to be pressed tightly against the reach 40 and prevent accidental removal of said reach from the groove 4B. It will also be understood that the end of the body part which has the extension 4l serves as a lever arm by which the rotation of the winding means 3| is facilitated. It will also be understood that the members 34, and the post 44, Fig. 3, form a cleat which constitutes the winding device 3|.

By employment of the tightener 29 the usual slip knot /la and the surplus length of line, Fig. l, which is put up in loops mb on the line may be left undisturbed during a line tightening or slackening operation, or the slip knot 48a and surplus line portion 4Gb may be entirely eliminated, in which event the two ends of the line would be directly secured to each other. Although only one tightener 29 is shown on the pulley line 4|, it should be understood that more than one may be used if desired. For example, a tightener may be put on the line prior to hanging clothes thereon and if the lower reach sags too much after some of the clothes have been put thereon another tightener 29 may be put on the reach 40 to take up the sag produced by the weight of the clothes. This may be repeated as often as it is found necessary.

The form of tightener 29T shown in Figs. 7 to 9 is composed of two major components,Y namely, a horizontal component or member St and a vertical component or member 8|. The member 80 includes the winding means 3h' and the holding means 451. The vertical member which is an arm or lever serves as means by which the tightener may be operated to rotateA the winding device Sir to wind up a portion of the line thereon. The members 80 and SI are held together bya wood screw 82. To prevent turning of the members t!! and 8| with respect to each other they are interlocked. For this purpose the member 8! is provided with a slot 83, Fig. 9, and the member 3| with a slot 84, Fig. 8, each member tting into the bottom of the slot of the other member.

After a portion of the line is wound on the reel 3|r of the tightener 29r the holding means fir is placed under the line portion 4| 2 as in Fig. 7, so that said line portion engages in the groove fitr and behind the tongue 48T. It will be understood that the member 8| may hang down from the line portion 4U, as shown in broken lines in lFig. la and may be comparatively long to facilitate rotation of the tightener during a line Winding operation. The member 8i), however, is comparatively short to occupy a minimum space between the articles of clothes on the line.

When the line portion 4ta is to be unwound from the tightener 2dr, to loosen the line, the holdingV means is rst moved from engagement with said line position and the tightener is in the position shown in broken lines in Fig. la with the Along arm di extending from the line so that the tightener may be permitted to rotate, under the influence of the tension or taut condition of the line, about an axis which is parallelto the Vertical member 8|. During the winding of the line portion, however, the tightener is rotated about the axis of the reel 3|r, which extends at right angles, to the vertical portion or arm 8|. The

. end c5 of the member 8l is shapedsoras to faciliwhen the tightener 2dr rotates freely to unwind the line, while the handle di extends vertically downward from the line, as indicated in broken lines toward the right in Fig2 la. In this position the handle 8| may be guided by both hands of the operator to permit the tightener to rotate about an axis which is substantially at right angles to the winding axis and substantially parallel to the handle Bl.

The vertical member Si extends upwardly from the member 85 and is provided with a roller 8615 which runs on a spindle 8H and travels on the reaches Mx and Hy of the clothes line Mv, Fig. la, to hold said reaches and lower reach of the clothes line close to each other.

It should be understood that the winding device 3 |r and the holding means llr in addition to performing their individual functions also cooperate to assist in holding the member 8| in an upright position in a plane extending transversely of the line.

The roller 861i is located in a vertical slot 86:1: and a diagonally disposed slot 92 communicates therewith, through which the reaches 4|:c and Illy may be passed to the reach accommodating slot x in which the roller 86 is located. To do this, however, it is necessary to swing or tilt the upper end of the device 29.1* laterally, rightwardly in Fig. l, until the slot t2 is substantially parallel with the reaches Mx, diy so that they may be passed freely through the slot. This is also done when it is desired to remove the reaches from the device 29,". It will be understood that the diagonal arrangement of the slot By prevents accidental detachment of the device 29s from the reaches da: and diy.

The holder 25h" comprises a horizontal member 3d and a vertical member or body part 8|. The

member Si) is composed of a winding means 3|r and holding means 45T. This form of device is constructed for use on a clothes line lilo having four reaches Mw, lilrc, My, and file, Figs. la and 7. The reaches da: and Hy are intermediate reaches and they travel in the same direction, the reach Hx extending from pulley 45e, Fig. la, to a pulley dd, and the reach Hy extending from a pulley de to a pulley ttf'. The outer reaches tlw and die also travel in the same direction but opposite to the direction of travel of the reaches 4iso and illy. This type of clothes line is disclosed and claimed in my application, Ser. No. 243,955, led December 5, 1938, now Patent #2,292,415, dated August ll, 1942.

The upper end of the device or holder 29r includes a hook-like portion 88 which extends over the upper reach 4| w of the clothes line to keep the reach Hw properly spaced with respect to the lother reaches. Two guards 89 and 96g are provided to prevent accidental detachment of the device 291* from the upper reach 4|w. The guards are formed by a diagonally extending slot 9| through which the reach Mw is passed to a position under the hook 8S. To do this, however, the holder is tilted to bring slot 9| substantially parallel t0 .the reach Mw of the line ticalposition the

guards

89 and 90 are-so related-y that it is impossible for the reach to pass out through the slot 9i.

A roller 93 is also provided in the slot 88x which may ride on the reaches Ma: andI Myin case the device 291 becomes inverted by the articles of clothes when. they are wrapped around the line by the Wind.

It should be understood that the vertical com-- ponent 8| may reach an upwardly extending position, as at the yleft of Fig. la, when the line is'suiiiciently tight and the reach 41.2 has been placed in the holding means 46T; It is then merely necessary to tilt the device, upper endrightwardly in Fig. la, so that the upper reach lll-w may be inserted throughA the slot 9| and that the intermediate reaches Mm and My may be inserted through the` slot 92 as above described.

It should also be understoodv that at the completion of a winding opera-tion the verticalcomponent 8|- may come to rest in a downwardly extending position with reference to the lower reach Mz, as shown in dot-and-dash lines at the right in Fig. la. In this eventit is necessary to first swing the device 29t about the axis of the lower reach Me to the upwardly extending full line position above the reach Mz. The device 29t may then bel swung upper end leftwardly in Fig. la until. the slots 9|- and 92 are substantially parallel with the line so that the ireachels Mw and 413:, My may' be inserted through the slots.

A modified form of holder, 29s,' is constructed for use on the two reach clothes-line 4I shown in Figs. 1 and 6. It also includes a horizontal component 88s and a vertical component 81s, the horizontal component having a Winding device 3|s and a holding means 45s like those of the holder 291". The component 8|shas a slot Br.

with which a diagonally extending slot 86g communicates and through which theupper reach 4B may be passed to a roller 86 in the slot 86x', said roller being provided to facilitate transit oi the holder on the upper reach 40'.

It will be understood thaty the holding device 5r of the device 2ST, Fig. '7, in addition to preventing reverse rotation of the winding device 31T, while in engagement with the clothes car-- rying reach, is also effective to prevent rotation oi said device about an axis which is substantially in alignment with the axis of the vertical component 8l and thus prevent binding of said component on the reaches Mw, 41x and Hy. This tendency to so rotate the holder 251- is caused by the sections ofthe reach le atopposite sides of the componentl because they lie in adjacent vertical planes and produce the effect of a couple. Similarly the holding means 55s, Fig. 6, prevents rotation of the holder 33s about its vertical axis to preventbindingoi thecornponent 8ls on the reach 4Q',

rEhe type of holder illustrated in Figs. 6 and 7 may also be applied to the clothes carrying reach of the line without winding up a portion of the reach on they winding device in the event that the line is tight enough. How this is aocomplished will now be described in connection with the holder 291'of Fig. 7. The clothes' carrye ing reach die mayrst be' caused tolle on the top face of that portion of thewinding device to the left' of the 51017331: Figs. '7' and 9; it' may then be extended through thev slot 331, then aroundrthe` lower face of thatl portion of the winding device tof the right of the slot and is finally passed over the extension of thev holding means 45s;y Thus it will be understood that under this condition the winding device 3I's and the holding means 45s cooperate tol form a bight in the reach lle which grips the holder to cause it to travel with said reach, and also cause the.l holder to extend perpendicular to the reachesof the line to prevent accidental passage of the reaches through the diagonal slots 91| and 92 in Fig. '7 and 8611 in Fig. 6.

While certain preferred embodiments of the invention have been described, it will be understood that certain parts may be used with others and that changes in the form,l arrangement, proportions, size and details thereof may be made without departing from the scope of the inven tionl as defined in the appended claims.
