R. HESKEL SAFETY DEVICE AGAINST THEFT AND BURGLARY Filed April-14, 1924 1 5515; 1' Z UNITED STATES PATENT OFFICE.

RICHARD HECKEL, OF DR-ESDEN, GERMANY.

SAFETY DEVICE AGAINST THEFT AND BURGLARY.

Application filed. April 14, 1924. Serial No. 706,607.

To all whom, it may concern:

Be it known that I, RICHARD HnoKnL, a citizen of the German Republic, residing at Dresden, Germany, have invented certain new and useful Improvements in Safety Devices Against Theft and Burglary, of which the following is a specification.

It is always desirable to create new technical means for preventing theft and burglary. Electric alarm bells do not give sufficient security as they are easily out. Safety chains for attaching hand bags, trunks or the like do not protect against theft as it is easy to out either the safety chain or the handle of the hand bag or trunk.

This invention has for its object to improve the safety devices against theft and burglary in a perfect manner and the improved safety device consists of two wire spirals telescoped the one into the other and wound in opposite directions. The wires which cross one another form an armour which cannot be out even with the best and sharpest tools.

Several embodiments of the invention are shown by way of example on the accompanying drawing, in which Fig. 1 shows the preferred form of construction of the safety device.

Fig. 2 shows a modified form of construction of the safety device.

Fig. 3 shows the safety device used as protecting cover for accessible parts of electric leads.

Fig. 4 shows the safety device used as protecting cover for accessible parts of the lead for alarmbells.

Fig. 5 shows partly in section one end of the safety device used in connection with bicycles.

Fig. 6 shows the safety device shown in Fig. 5 in the position of use.

Fig. 7 shows the safety device as handle for a hand bag.

The tube shown in Fig. 1 which is composed of an outer wire spiral a and of an inner spiral b, is common to all embodiments of the invention. The spirals are wound in opposite directions. The wire tube is flexible. Instead of the two spirals a, b a greater number of spirals may be used. Each Wire spiral is made separately and cut off into pieces of convenient length.

The spirals are preferably made from best hardened metal strings. The two spirals are telescoped the one into the other and united at both ends by soldering or welding. The outer Spiral (4 is for instance left handed and the inner spiral right handed. As shown in Fig. 2 a core 0 consisting of hardened wires may be inserted into the telescoped spirals a, 72.

Figs. 3 and 4: show how the safety device is used for protecting the leads of an alarm bell. Those parts of the lead cl which are accessible so that they might be out are covered by a protecting tube as shown in Fig. 1, especially the points where the lead enters into or comes out of a building. The protecting tube may be painted or have a rubber coating.

The device for securely attaching hand bags or parcels on the basket rack, for securing bicycles or other vehicles, shown in Figs. 5 and 6, consists of a tube as shown in Fig. 1 which might be covered with a rubber sleeve. On the two ends of the flexible tube, which preferably are not covered with a rubber sleeve, metal sleeves e are screwed and fixed which terminate each in a lug f. The two lugs f stand at right angles the one to the other. For securing a bicycle against theft the flexible tube is inserted through the wheel in the well known manner, whereupon the lug at the one end is pushed through the lug of the other end and a padlock or the like is fixed in the projecting lug. Instead of a padlock a safety lock of any convenient type may be used.

The safety device according to the invention does not only secure perfect protection against theft and burglary but is also of elegant appearance, easy to carry in the pocket and further to be used as a weapon.

The safety device, which must in this case be of greater length, is also adapted to be used for securely attaching the spare tyres on motor cars.

Fig. 7 shows the device adapted to be used as handle for hand bags, trunks or the like. For the forms of construction shown in Figs. 5, 6 and 7 the flexible tube with cover shown in Fig. 2 may be used.

I claim 1. A safety device against theft and burglary comprising in combination a right handed Wire spiral and a left handed Wire spiral telescoped the one into the other and united at the ends by soldering.

2. A. safety device against theft and burglary comprising in combination a right handed Wire spiral and a left handed Wire spiral telescoped the one into the other and united at the ends by soldering and a core of twisted Wires in said Wire In testimony whereof I aflix my signature in presence of two Witnesses.
