mks-Moe ERNST KLEMM BY 7 F 7 4% ATTORNEYS strip by the fact that at the United States Patent Ofiiice to a method of laying strip with lateral spikes or teeth.

The invention relates fencing material provided According to the invention it is proposed to wind the fencing material, which, together with its spikes, is flattened out in a plane, in the form of a delivery spool, and, after securing its free end to a stationary object, for example a wall, a tree or a post, to draw it progressively from the spool in such a manner that, in addition to the rotation of the roll of strip about its spool spindle, caused by the Withdrawal of the strip, a rotation about a spindle running at right angles to this spool spindle, for example about a spindle lying in the direction of withdrawal, is positively effected by the tension exerted on the strip.

In this way, the strip which is laid across the country, is twisted about its longitudinal axis so that the lateral spikes or teeth of the strip now project in all directions. In this manner the strip can achieve a particularly good deterrent and defensive effect, particularly if the lateral portions are not only spiked but are also made as cutting edges, so that in this respect it is superior to barbed wire constructed and used in the conventional manner. To this must be added the greater strength of such a strip fencing material twisted about its longitudinal axis, and the possibility of producing it particularly easily by machine.

The said second rotation of the spool, together with the spool carrier, about the spindle of the pulled strip can be effected during the progressive withdrawal of the delivery point, the strip is conveyed from the spool carrier through guides which give it a positive twist so that the elastic reaction of the strip, which may consist of steel for example, at this point, sets the spool carrier in rotation.

The second rotation of the spool and the spool carrier can also be imparted thereto by the fact that the friction of the strip running out is used to produce the said rotational movement by means of any desired transmission members. The rotation of the spool carrier may also be transmitted to the spool carrier from the likewise rotating spool spindle of the spool carrier by means of any desired transmission members. The extent of the twisting of the strip running out can be varied by adjusting the parts. causing the second rotation of the spool carrier.

The invention further relates .to a device for carrying out the said method of laying strip fencing material which is provided with lateral spikes or teeth.

This device consists of a frame to which is connected a carrier receiving the supply of strip in its smooth, flat form. The carrier is arranged to rotate both about the spool spindle and also about a spindle at right angles to the spool spindle, lying particularly in the direction in which the strip is unwound. There is also connected to the carrier a device which rotates it about the lastmentioned spindle as the strip is progressively unwound.

The frame taking the spool carrier may be made portable or mobile.

I Patented Oct. 13, 1959 2 The portable frame is preferably provided with a handle by which it can be held while the strip is being withdrawn, or it can be made entirely in the shape of a handle, in which are mounted both the spool spindle and the spindle at right angles to the spool spindle. I

The device effecting the rotation of the strip carrier and the said second spindle may, for example, consist of a guiding device mounted at carrier and twisting the strip as it runs through. Said device may, for example, be constructed in the form of fixed guide surfaces or pairs of rollers with rotating rollers between which the strip runs.

The invention further relates to the formation of a fencing strip with marginal teeth, marginal hooks or marginal spikes, which is suitable for winding in the form ofa spool on the device according to the invention, and which can be progressively withdrawn from the spool carrier, while being twisted about its longitudinal axis.

According to the invention, the fencing strip is provided along its longitudinal edges with a row of notches which are made open on the outside, so that on each of the marginal portions of the strip left between the two notches, two teeth are produced, facing in opposite directions. The notches at the edges of the strip may conveniently be given rounded contours, for example oval.

Other characteristics of the device according to the invention, for laying a fencing strip, together with further embodiments of the fencing strip itself, are illustrated in detail in the accompanying drawings.

In the accompanying drawing one embodiment of a device for carrying out the method of the invention is shown by way of example.

Figure 7 to 10 show dilferent embodiments of a toothed strip made according to the invention.

Figure 11 shows an approximately lenticular cross-section of the stri Figure 12 shows such a toothedstrip wound up in the form of a flat spool.

In detail, the reference numeral 1 in the figures refers to the handle of the device, plastic, metal or the like. lengthwise. A spindle 2 is mountedfor rotation in the bore, with its rear end secured to the handle 1 by means of a disc 3 and a pin 4, or by similar means. At its front end, the spindle 2 carries a forked holder 5, may consist, for example, of sheet metal or the like. A spindle 8 is mounted on this holder 5 in the bores 6, 7, being secured against falling out by means of a spring 9 fitted in a groove 10. To facilitate handling, the spindle 8 is provided at one end with a ring 11, which is articulated to the spindle 8 at 12. The spool, with the fencmade for example of .wood,

ing strip wound thereon, is mounted for rotation on the be mounted to rotate freely or be.

the delivery end of the spool' This handle is bored through which 1 if 13,which may conveniv be able to rotate about two spindles, once about the spool spindle 8, and again about the spindle 2, which is mounted for rotation in the handle 1.

At the front end of the two arms 17 and l8 of'the forked holder 5, a guide de vice for the strip which is'running out is provided which serves to delay the strip as it runs out, and set the spool 16 in rotation-about the spindle 2. i For this purpose a pair of rollers 19, 20 is mount ed between the arms 17, 18, the rollers of which are spaced so as to provide a certain amount of play in relation to the thickness of the strip. In front of the pair of rollers 19, 20 there is provided a plate 21 which is fixed to the'arrns 17, 18 of the holder 5. This plate is provided with a slot 22 which is somewhat wider than the cross-section of the strip, and equipped with two upwardly projecting pins 23 and 24, for example lying diametrically opposite one another. These pins may, for example, be

made in the form of screws which are threaded intothe plate 21. A plate 25, which can be pivoted or swung about;

which are likewise spaced to provide sufiicient play according to the thickness of the strip. a j

The upper plate 25 is further provided with one or more recesses 35, 36, in which a sprung stop 37 engages when the plate 25 is twisted round.

The strip is laidby means of the laying device,---as shown diagrammatically in Figure 6. Thestrip 38 is secured. by its free end to a post 39. The laying. apparatus as shown in Figuresl and 2 is simply heldby the handle 1 and the strip is withdrawn by the operator walking forwards in the desired direction'oflaying-.- ,The

apparatus may conveniently be held so that the axis of V the. handle 1'runs approximately horizontally in the'direction in which the. strip is dispensed or laid. Consequently the spool 16 rotates-first about-its axis as the unwinding progresses; furthermore the strip is twisted or turned between the. pairs of rollers 19, 20 and 33,- 34',

in relation to the disc 21, which-is fixedto the frame of:

the device, according to the settingof the upper disc 25." This twisting of the strip exerts a reaction of the spool 16, including the spool carrier 5, so' that the car rier 5, with the spool 16, rotates about the spindle-2; according to the torque. This rotation is insufficient, how

ever, to compensate'for the twisting occurring between the pairs of rollers 19,20 and 33, 34, and in particular for the permanent portion of the deformation; instead the strip running out from the pair of rollers 33,134

'remains twisted in such amanner that each successive portion is further twisted in relation to the preceding portion. 7 Thus during laying, a strip is obtained which is evenly twisted along its entire length. The strip 38 can then again be secured to a suitable support, for example, a post, at the desired distance from thestarting point 39,

and may continue to be laid, with progressive twisting, as long as the supply of strip lasts.

Figure 5 shows diagrammatically the'twisting of the pairs of rollers 19, 20 and 33, 34 and hence the extent of the twisting to which the strip is subjected between-the pairs of rollers; If the plate 25 is provided withseveral recesses 35, 36, theextent of this twisting can be adjusted accordingly.

The invention is in no way restricted to the particular embodiment of the laying apparatus described. The

whole arrangement of this apparatus as well'as the individual structural details thereof may be altered and amended as desired, within the framework'ofthe inventive idea. For example, the frame serving to take'the spool to be unwound, and the handle, or the connection of this frameto a'rnobile'ori movable fra'm'e' base m'ay be designed as desired. The frame '5 of the strip could, for example, be rotatably connected to a carriage in such a manner that the axis of rotation lay substantially in the direction of motion. Likewise the device provided at the delivery end of the strip, by means of which the strip is twisted, can be designed as desired. Instead of rotatable rollers, for example, fixed guide devices'could be provided. Furthermore the rotation" of the spool about its second spindle could be brought about by means of other" mechanical driving and transmission-- members, for example by the force of an additional spring which is automatically released by the'progressive laying of the es's'entialjfor'thesupply of strip to be wound in-the-form' of aflaf, spiraispool, like a roll offilm. The entire supply"'offst'rip' could also. be wound in other ways, for exarnplelike'a-spool of yarn. Examples of flatformations i,

of they s'tri'p'which could be wound up, including their spikes, ,are sho 'n'in Figures 7 to 10.- Thespikes of-the strip mayhem be formed, for example, by'stamping holes out of'a solid' strip of metal. With this flat formation thereis' no difficulty in winding and unwinding the strip; During the subsequent twisting of the StIlPyhOWfiVCl', the

spikes" of the strip point in all directions; Particularadvantages 'are' offered by theuse of a strip, the edges of which are like cutters so that the spikes of the laid stripexert notonly a pricking-but also a cuttingdeterrenreneee Such a formation of the strip is obtained,

foff'example, if it is made with a bulged cross-section as shown'in'Figure 11, for example by rolling. The cutting-efiect may also be achieved by subsequent rolling or grinding of the finished strip provided with barbs:
