ARTHUR. oUELLE'r, or NAsHUA, NEWv HAMrsHIRE.
CORD-GRIPPING DEVICE. i
Application led August 18, 1924.` Serial No. 732,592.
To all whom t may concer/n.:
Be it known that I, ARTHUR OUELLn'r, a Vsubject of the King of Great Britain, and native of the Province of Quebec, Canada, and resident of Nashua, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful lmprovements in Cord-Gripp'ing Devices, of which the following is a specication.
This invention relates to means for suspending articles such as plumb bobs and electric lamps in desired locations without requiring the tying of any knots in the suspending cord.` Y
When a house is being built, it is customary for the mason or carpenter to hang a plump bob from an overhead line, and when the weight is to be shifted in vertical posi-V tion, and sometimes when to be shifted along the overhead line, the existing knots must be 11n-tied and then new knots made. This involves a loss of time which is saved by my improved device. Moreover the tying of the knots requires expert work to effect suspension 0f the plumb bob in exactly the correct position. With my device the exact position can be easily and quickly secured and maintained.
Many machine shops require, at times,
that an electric lamp shall be located, per-V haps temporarily, in a convenient illuminating place relatively to a particular machine, and it is customary to then use a string tied at one end to the circuit-wire cord and then so manipulate the string and tie it that the lamp will hang in the desired position. As
will be readily understood from the following description and the accompanying drawings, my suspension device will enablean electric lamp to be quickly suspended in the position needed.
' 0f the drawings Figure 1 illustrates my invention 'in use in connection with a plumb bob.
Figure 2 is a side, elevation of the N- shaped hook.
Figure 3 is an edge View of the same.
Figure 4 is a side elevation ofthe upper part of the reel or carrier for surplus cord.
Figure 5 is an edge view of the same.
Similar reference characters indicate similar parts in all of the views.
The principal element of my device consists of a thin metal N-shaped hook or clip A the two cord-biting notches a of which are substantially parallel but opening in opposite directions. rThe walls of the notches are straight except at their extreme inner and outer ends, and each notch is very slightly tapering in form so that a cord such as illustrated at D in Figure l will be reliably permanently pinched when drawn toward the inner end of such notch.
A plumb bob, such as used by masons or carpenters, is illustrated at B, the cord for suspending it being indicated at D. C inditov cates the usual overhead line from which y overhead line C and with the suspending..
cord D, while the lower one is engaged with the suspending cord D at two points so as to maintain a loop inthe latter. Y Such use enablesthe height at which the plumb bob or other weight shall hang to be adj usted without touching, or having to reach up to, the
upper hook A, because all variation in the vertical position of the weight can be effected by varying the amount of cord contained in theloop hanging from the lower hook A. `The upper hookV can usually be left Lso undisturbed so long as its position along the line C `needs no adjustment. When the weight needs to be raised or lowered, either notch of the lower vhook can be caused to grip the cord D at a new point.
Owing to the fact that the two gripping notches a, a, are substantially straight and parallel, and open in `opposite directions,- the compound hook when hung on one line, as the line C, will not tip far over and will therefore present its other notch in upwardly open position ready to receive the other cord, as D, without requiring hand manipulation of the hook to hold it with the second V`no tch -facing upwardly. In other words, the upper compound hook A can be deposited on the line C and it will hang so as to automatically present an upwardly facing notch for the cord D to be deposited therein, after which a downward lll i cord in the notches ot the hook A, a sepa-- slight pull on the cord D, or even the mere weight ot the plumb bob, will automatically make all tast. y
For the reasons hereinbetore stated, itis preferable to employ two of the .hl-shaped 'or compound hooks so that the lower one canvbe usedv for simply taking,` up more or less slack in the suspension cord D. This is especially preferred when the overhead cord C can not be readily reached. Such cord or line is sometimes at such height above the location ot the worker as to require a ladder to enable said worker to reach a hooi; on such overhead line. However, one compound hook alone can he used both tor determining' the position along; the line C and the vertical position ofthe plumb bob, when the line C is not too high.
ln order to accommodate ample length of the cord l) tor all purposes, and yet maintain the surplus in accessible but out otl the way position, l provide the reel or carrier E with a hook member A having` a linegripping notch e as illustrated by Figures Le and 5. Such reel or carrier, with ample length ot cord D, and with a pair of the N-shaped hooks, and a plumb bob, may be easily carried, when not in use, in the kit or tool bag or box ot a mason or carpenter, or even in his pocket.
From the, description already given, it will. be readily understood how an electric lamp can quickly be suspended in any desired position relatively to a machine in a machine shop or elsewhere. ln such case, if it is not desirable to `grip the circuit-wire rate suspending` cord may heemployed for connecting' such circuit-wire cord with the said hook A..
A I do not limit myself to the' uses of the invention in the manners illustrated and describedas there are various other ways of using' the compound hook in connection with cords or lines employed for various purn poses. For instance, such hooks may be usefully employed for taking up slack in clothes lines. rllhe most important utility however is when something,` carried by a cord is to be temporarily suspended from a transverse overhead line. rlhe shape of the compound hool; is such that at'no time does it require any careful lateral manipulation to eltect engagement with either ot' such cords or lines. This is chiefly due to the fact that after a readily effected engagement with the overhead line, the hook autr matically hangs in position to receive the cord or other line in an upwardly lfacing,- gripping notch.
Having now described my invention, claim cord gripping device comprising an elongated substantially rectangular plate the outer side edges of which are straight from end to end, said plate rhaving,` a notch eX tending' from each end nearly to the other end, the walls ot each notch being straight and smooth and closely approaching` at the extreme inner end' of the notch to enable a cord passed into either notch from its mouth to its extreme bottom to be gripped at said bottom, the two notches extending` sntliciently close to opposite ends ot the plate to enable the plate7 when hung` from a line engaged in one notch, to present the other notch in an upwardly opening direction.
In testimony whereof l have affixed my signature.
ARTHUR oUELLET.
