WIRE-WINDING MACHINE.

To all whom z'tmay concern:

Be it known that I, EMORY GLENN SIMP- SON, a citizen of the United States, residing at Detroit, in the county of Wayne, have invented a new and useful Improvement in Wire-Winding Machines, of which the following is a specification.

.This invention relates to machines for winding wire about loops, and is especially intended for winding the ends of a loop in a stay wire for aeroplanes. The features of construction and the novel parts will appear in the more detailed de-. scription following.

In the drawings,

, Figure 1 is a longitudinal section of the machine partly in elevation.

' Fig. 2 is a plan view.

Fig.- 3 is a cross section on the line CC of Fig. 1.

Fig; 4 is a cross'section of the loop-holder in closed position.

Fig. 5 shows the same part in open posi-. tion.

The frame of'the machine is designated a adapted to take the sleeve 0 which is secured in position bythe set screw d. This sleeve performs the double function of acting as and has a head 6 provided with an opening a bearingshaft and a socket for the removable loop-holder e. The loop-holder e is a split cylindrical member whose construction will be better understood by referring to Figs. 4 and 5. This comprises two parts of a cylinder hinged together by the knuckles f and the knuckle pm g. At

the center of the cylinder the two-part cylinders do not quite'meet by a space suflicient' to hold the two ends of a wire loop. The consequence is that when the cylindrical holder is opened up, as shown in Fig. 5, the wire looped back upon itself may be inserted by laying: it in the opened cylinder. The cylinder may be closed up as shown in Fig. 4, leaving the loop portion of the wire exposed as shown in Fig.1 at the endof the cylinder. Pressure pins it operated by coil springs serve to afford a friction on the loopedends of the wire so as to hold the same frictionally. Obviously when the twopart cylinder is inserted in the socket formed by the sleeve 0, this serves to hold the'two parts together.

On the outside of the sleeve 0 is journaled Specification of Letters Patent.

pulley n and connected with this pulley by means of the clutch 0.

This rotating head carries a-spool-holding stud 7) upon which is adapted to be rotatably mounted the spool of wire. q. A tension deviceis located on the head opposite the spool-holding stud and comprises simply asegmental block 1" with a circumferential around which and in which lies the wire to be fed on to the work. The pivoted bar 25 has a foot 10 adapted to press against the wire that lies in the circum- 1 ferential groove. This foot 'u, is urged against the .wire'by means of the tractile spring '0 whose tension may be adjusted by turning the screw rm so as to lengthen or shorten the spring. Obviously by lengthening the spring the pressure on the wire is greater and consequently the tension greater between the tension block and the loop or work.

When the machine is set into operation by shifting the clutch lever ,w, the wire spool and tension device are caused to rotate about the stationary loop-container and consequently winds the wire uponthe loop, but this winding would be a mere piling up were it not for the fact that the work is advanced just the proper distance continuously to make the wind a true and tight spiral. This advance of the work is secured by connecting the power shaft and threaded shaft 3 by means of a properly calculated reduction gearingz. A- slide 1 traveling longitudinally of the machine ina. slide-way has a liftable half nut connection 2 with the threaded shaft; hence the slide being constrained from rotation and the threaded shaft engaging with the nut, rotation of the shaft causes the slide to travel away from the stationary head I) of the machine. A hook 3 is carried by the top of the slide and is adapted to be hooked into the looped work. Consequently when the rotating head begins to rotate the work simultaneously begins to travel away from the stationaryhead at just the right pace to form a true but tight spiral.

The stem 4 rises from the half nut 2 and the nut may belifted 0E from the threads of the shaft 3/ 'by means of the lever 5.. The

compression spring 6, however, normally tends to keep the half nut in engagement with the threads.

By the-machine here described, loop ends may be bound together and their windings machine laid, as distinguished from what has been the practice heretofore to wind these by hand. The prior practice-has been hard, slow and less satisfactory work than is performed by this machine.

2. In a machine for the purpose specified, the combination of a stationary head, a rotating head head, and a loop-holding cylinder insertible in a cylindrical socket of the stationary head and comprising a pair of part cylinders hinged together and adapted to pinch the ends of the loop between the same.

3. In a machine for the a stationary head, a rotatin head journaled about the stationary hear? and having a journaled about the stationary purpose specified,

spool-carrying member and a loop-holding member-insertible in a socketinthe stationary head axially of the rotating head and comprising a pair of cylinder parts hinged together.

4. In a' machine f0'r the purpose specified,

a stationary head, a rotatmg head provided a stationaryv head, a rotating head provided with a spool-carrying device and jofirnaled about the stationary head, a loop-holding cylinder insertible in a socket in the stationary head axially of the to engage the loop ends between them and containing one or more presser pins for frictionally engaging theloop ends, and means for engaglng in the end of the loop and ad'- vancing the same with respect to the loop-.
