Specification of Letters Patent.
Patented Jan. 18, 1910.
Application filed December 9, 1907. Serial No.405,765.
especial-ly adapted for use with the y:flexible conductors or cords used with pendent electric lights, telephone receivers and the like, for adjusting the 4height of the instrument or length of the cord `by forming therein va readily variable loop.
In the accompanying drawings, Figure l is a side view ot' vmy device with the cord in `place and held thereby. Fig. 2 is a like view with the cord so far released that rit may be readily slipped for adjustment Fig. 3 shows a view, looking vfrom the right in Fig. l the cord being omitted. Fig. 4 is a view analogous to Fig. 3, showing a modification in which two holding devices are employed. Fig. 5 is a Iview similar to Fig. 1, showing also two holding devices.
In these views, A represents the cord to be held and B the holding device, which for purposes of illustration is shown in Figs. l, 2, 3, as formed, from a one-piece oblong rectangular block having the angle at its ends slightly rounded, by cutting the block through from side to form a passage E and a communicating passage or opening C of such size and form as to leave, at what is shown as the lower end of the block, a body portion with two comparatively thin flat arms D, D upon opposite sides oi' the opening C. The material of the block is resilient, wood being sometimes employed, and the form and width of the passage E are such that by pressing the arms D, D toward each other it may be closed. If the arms be equal and homogeneous in character both arms spring equally, but this is not indispensable. The passage E being thus closed, as shown in Fig. 2, the parts above the opening C, upon opposite sides ot' the passage thus closed, are bored through to form passages F F somewhat larger than the cord to be used. The body at the opposite end of the block is also bored to Jform a passage G in which the cord to be used will tit closely and be frictionally held with comparatively slight force. The entrances to the bored passages are preferably reamed to yfacilitate inserting the cord. It now a suitable' cord A I'be inserted and'drawn Iout more or less from the opening C, as at C', it will rbe `bent somewhat sharply across the passage E when the latter is allowed to open ,under the resilient action of one or nboth arms, which 'throws the two passages F F out of alinement. The cord is .then securely `held although it `otherwise slides freely in the passage, lbut obviously it may be instantly released, uby pressing the walls D, D toward each other withfthe fhand, so that the loop .may lbe readily varied. d
F 4 shows :two devices B, B2 like that already described, (except that the frictionally holding cord passage is omitted,) secured together :by rivets or the like, one
,being jiirst turned end .for end. Iny this form both ends of :the loop portion of fthe cord Yare held by similar devices. F 5 shows la different way ici duplicating the holding means, Ethe device being in eli'ect twoV identical devices like that of Figs. l, 2,3, 'formed' in opposite ends of a longer block B3. As
shown, the rictionally holding ycord lpassage is retained, as shown at Gr, two loops being formed. Neither' the presence of this passage norkits utilization it present is in.- dispensable. In any of the devices, the length of cord lying in the passage E and the abruptness of bending depends upon both the width and the inclination of the passage. It may also be observed that whatever the inclination, the larger' cord passages are readily bored when the parts are pressed together as in Fig. 2 since the material is then practically continuous, and still furi ther, it is obvious that the exact construction shown need not be followed.
VVhatI claim is:
l. In devices ot' the class described, the combination of a member provided withl a passage in which a cord may be held, of a coacting member provided with an analogous non-alining passage and secured to the first in position to receive in its passage a portion ot' a cord at some distance from the portion lying in the passage of thefirst member, one of said members being adapted to otter yielding resistance to bringing the two npassages into alinement.
2. In devices of the class described, the combination with a member having at two widely separated points, passa es in which a cord may lie with its interme iate portion connected at one end to the first member and having a cord channel normally at one side of a straight line between said passages and in position to engage a cord at a point some distance longitudinally from each of said passages, said second member being adapted to yieldingly resist force tending to move its channel towardalinement with the said passages; whereby a cord passing through said passages and channel is bent laterally and held without shearinO0 action.
8. In devices of the cIass described, the combination with a member having at widely separated points passages in which a cord may lie with its intermediate portion approximately in a straight line, of a second resilient member secured to the first, having a cord channel normally inclined to a straight line between said passages and in position to engage said intermediate portion at a substantial distance from said passage, and yieldingly hold in deiiected position a cord passing through said passages and channel.
4. A cord holder having two approximately parallel materially unequal resilient arms rigidly connected at one end, one of said arms having at its free end a projection provided with a cord receiving passage and the other having an inwardly extending projection at a substantial distance, longitudinally, from the first projection and provided with a normally non-alining cord receiving passage.
5. A cord holder having a body provided l with a passage adapted for frictionally holding a suitable cord and with two approxi` mately parallel, resilient, material unequal arms extending from said body and having inwardly extending oblique faced projections provided with normally non-alining cord passages normally separated longitudi nally with respect to a cord passing therein.
6. A cord holder provided with two Hat resilient approximately parallel arms having at one end an integral connecting portion provided with a cord passage and having at their free ends oblique faced overlapping projections provided with cord passages adapted to register only when the arms are sprung inwardly.
7. A cord holder consisting of a block of resilient material cut through between its ends to form an opening bounded on two opposite sides by thin walls and to form a normally open passage dividing obliquely that portion between said opening and one end of the block, the two parts oi said portion being cylindrically bored in an approximately axial direction to forni cord passages, and the corresponding opposite end portion being similarly bored, substantially as set forth.
In testimony whereof I aiiix my signature in presence of two witnesses.
