ART OF MAKING LIGHTING-OUTFIT FESTOONS Application filed Iv'Iay 14, 1925.

T all whom it may concern: Be it known that I, Lnsrnn HAFT, a citizen of the United States, and a resident of the city of New York, in the county and State of New (York, have invented certain new and useful Improvements in the Art of Making Lighting-Outfit Festoons, of which the following is a specification.

The invention relates to lighting outfits of the type which have become known to the trade as Christmas tree, or decorative, outfits.

Such an outfit, as these outfits have long since become standardized, consists of eight miniature electric lamps which are wired in series to lead wires connected at one end to a standard attachment plug or other connector by which the outfit is attached to a lamp socket or other outlet in a standard lighting circuit; and when provided, in conformance with an earlier invention of mine, with a complementary socket or connector which is connected in multiple with the lead wires and is adapted to receive the attachment plug of a second outfit, Whereby a number of outfits may be connected up one to another, is known as an extension lighting outfit. The lamps are set into sockets which are mounted, the outer socket at the looped outer end of the two leads and the other seven on short lateral loops formed at intervals in one of the leads, by cutting the wire at the end of a loop and attaching it to the terminals of a socket, and since the loop of the inner lamp is located about three feet distant from the attachment plug and the loops are usually spaced about twelve inches apart each outfit will have a total length of somewhat over ten feet.

For a long period the festoons of the outlits that is, the looped leads to which the attachment plug and the lamp sockets are connected-were formed by looping a length of the usual sheathed insulated wire and running it through a braiding machine to thereby wrap and bind together the parallel leads within abraided covering which, straddling the lateral loops at their base, serve to de finitely llX these loops.

Recently, however, these covered festoons have been largely replaced by a so-called 'twisted festoon, ,Ojf lower grade and less Serial No. 30,201..

cost, in which the two leads have been bonded together only at the loops by a cord tied around the overlapped wires at the base of each loop and the other lead; and, as heretofore constructed, such twisted festoon has been made up upon a bench by taking the sheathed insulated wire from a reel or spool, tying its end to an end pinset in the bench, then carrying it along the bench and looping it around one after another of seven pairs of pins set transversely in the bench at the desired spaced intervals and finally around an outer end pin, carrying the wire straight back and cutting it at and tying it to the first or inner end pin, and then, commencing at the outer end, wrapping and tying the overlapped sides of each loop together and to the other wire, after which the festoon is removed from the pins and its loops are gathered together and cut. Thus, as seen, this bench method requires the operator to travel the full length of the bench four times in looping, measuring and tying each festoon and twice more in folding and gathering together the loops. Moreover, the twisted festoon not only does not have the neat finished appearance of the covered testoon but its hand-tied loops are apt to be loose and 'to slip or even to become untied altogether.

The object of my present invention is to simplify and otherwise improve the method of making the twisted testoons, thereby conserving factory space and otherwise cheap- Vening the cost of production, while at the same time improving the festoons themselves.

To this end the invention consists, essentially, in forming and bonding the loops in one of the lead wires of the festoon at a given bonding point and as each loop is completed moving the lead wires a measured distance and in so doing folding the leads between and gathering together the finished loops.

In practice the festoons are formed upon a suitable table, preferably from a plurality of sheathed insulated wires instead oi. from,

the folded lengths oi. a single wire as formerly.- The ends of the wires, which ends provide the cut outer end loop of the testoon, are drawn from reels or spools and carried along the table a measured distance, say fifteen inches, beyond a bonding point or machine, such for example as a suitable sowing or stapling machine, and there telnporarily secured, by a clamp for instance. A loop is then formed in one of the wires at the bonding point and the overlapping length of wire at itsbase are bonded together and to the other wire or wires by a thread, a staple, or otherwise. The loopand bonded wires are now moved along the table a measured distance from the bonding point and temporarily secured, as by slipping the loop over a measuring and gathering pin. A second loop is then formed in one of the w-iresand bonded together and to the other wire or wires at the same place and in the same way as before, and is in turn moved along and slipped over the measuring pin. These operations are repeated until the required number of loops have been formed and bonded. After the last loop has been moved along and placed over the measuring pin, the wiresare cut at the required distance, say three feet, therefrom, and the loops, which are all now gathered together upon the single measuring pin, are removed and-cut.

The lateral loops of the festoon be formed at the bonding point, either all in the saine wire or-alternatelyin each. of two wires, in any suitable manner, with or with-' outthe aid of pins. For bonding the overlapped loop wires together and to the otl'ier wire or wires,l prefer, and recommend. the

ed stapling machine may, lio'wcver, he used instead of the sewing machine. if desired: or the loops may be bonded by hand, either by acord wrapped and tied as heretofore or, for instance, by passing the end of each loop around the other wire or wires and back between its own two sides and drawing it tight.

, filly new method, by which thefestoons can be turned out by an operator seated in ii'ront of a table not over three to four feet in length, not only effects a great saving in the floor space of the factory but also in the movements and effort required on the part of the operator. Moreover, with an electrically-driven sewing machine, an experienced out 'fronrSOO to 600 fest-eons in an eighthour day, whereas, bythe oldbench method,

around the wires,-

the most skillful operator can not make up in the same time more than 350 of the less pleasing and less satisfactory festoons.

- The invention will be more fully described by reference to the accompanying drawings, in which- Figure 1. is a side or plan view of a lighting outfit festoon made by my new method; Fig. 2 is a plan view, more or less diagrammatic, of the top ofa table on which is mounted a sewing machine, showing two wires in processof being formed into a festoon thereon in the practice of my invenion; Fig. 3 is an enlarged. detail, showing in.perspective'parts of the sewing machine and of the wires shown in'Fig. 2; Fig. 4 is a view of the same parts, in side elevation and section respectively; Fig. 5 is a view, similar toFigu3, showing the-wires after the lateral loop has been bonded and they have been removedfrom the machine; Fig'G is a view, similar toiFig'. 3. showing parts of a stapling machine and of two wires, illustrating a modification of-the invention; Fig. 7 is a view of the wires shown in Fig. 6 after the lateral'loop hasbeen ibonded and they have beenremoved-fmm the machine; Fig. Sis a siderview of a portion of a festoon, illustrat ingia further modification-in: the formation andbondingaof the lateral loops; and-Fig. 9 is a detail oftheknot by which the loops of the fGStOOILOf Fi Q. 8 are;bo11ded.

As here. illustrated, 10- (Fig; 2) indicates the top-of ahsuilable table upon which is mounted a union single thread tacking niachine,'indicated at. 11.' This standard sewing machine, electrically driven, has a base with a iaperedior contri-icted forward end or horn 12, of a size adapted to form a loop ofsuitable length in a wire passedaround it,

andzforils use here iscquipped with. a

which holdthe wires a and Z) and, upon the other end ofthe tabletop, at the required distance from the-needle of the machine. usually about'fifteen inches, are mounted a spring clamp liland a incasurii'ig and gathering pin 20. l

In the formation ofa festoon upon'this table the ends a Z2 of the-wires, drawn from the spools, are-carried. past the sewing inachine=and secured beneath the clamp 15). One of the wires, the wire aas shown, is thenplaced in the slot'inthe' anvil and looped at 0 around the horn- 120f the machine and again placed in the slot in the anvil, and the wire b positionedabove and betweenv the pr or] zipping lengths of the wire a. The wires being thus.positi0ned and held taut, the machine is started, usually by pressing a foot-lever operating a clutch, and after the very brief interval taken to form the stitches required for a-satistactory bond (Z is stopped, by removing the pressure on the foot-lever, and in stopping 'aiscs the presser foot and automatically severs the thread. The loop 0 is now withd awn from the horn of the machine and, with the wire 6 loonded thereto, is moved to the right and slipped over the measuring pin 20. The wire a is again looped around the machine, the wire i) positioned thereover, and the machine starter and stopped as before, and the newly formed and bonded loop 0 is in turn removed from the machine and moved to and slipped over the pin 20. These operations are repeated until the desired number of lateral loops have been formed. After the last loop 0 has been removed from the machine and slipped upon the pin 20, the two wires, held taut, are out at the measuring line 21, say two feet from the needle of the sewing machine, thus providing ends a? b for connection with an attachment plug and three-foot leads therefrom to the last formed inner end'loop 0. The wire ends a o and the loops gathered upon the pin 20, usually wrapped together, are now drawn from the clamp and pin and are cut in the usual manner, thus completing the festoon.

In the modification illustrated in Figs. (3 and '4', 12 indicates the forward end of a bracket or base plate, and 15 the lower portion of the stitching head (arranged at right angles to the line of feed of the wires), of any suitable stapling machine of standard make, which here replaces the sewing machine. The usual clincher plate 13 of the machine is provided with a shallow transverse groove 14 and on each side of this plate are mounted two special pins 22. The operations for measuring, looping and bonding the wires into a festoon and folding and gathering up the loops as completed are substantially the same as those hereinabove described in connection with the sewing machine, each lateral loop 0 being formed by looping one of the wires aroundthe pins 22 and bonded by a staple clinched around its overlapping sides and the second wire.

In its further modification form illustrated in Figs. 8 and 9, the festoon is or may be made upon a table similar to that described, but the lateral loops 0, here shown as formed alternately in each of the two wireshand or otherwise, and is bondedby passing its outer end around the other wire and back between its own two sides, as shown in Fig. 9, and then drawing the knot tight.

It is to be understood that the invention may be still further modified in its various details without departing from the spirit or sacrificing the substantial advantages thereof.
