Filed Apr. 21, 1965, Ser. No. 449,889 3 Claims. (Cl. 89-1) ABSTRACT OF THE DISCLOSURE A process for driving anchoring devices by a tool in which a deflagrating propellant composition in pellet form is ignited by percussion to drive the anchoring devices. The propellant composition consists essentially of a mixture of pentrite and tetrazol-azo-amino-guanidine, the latter being present in an amount between and 30% by weight of the composition.
The present invention relates to processes for driving anchoring means or fastening devices by the use of boltsetting tools, and to propellant compositions for effecting such a process. In order to drive anchoring means, such as bolts and the like, into solid and strong materials, it is known in the art to use bolt-setting tools, where the driving energy is produced by the gases of combustion of an ignited powder charge. In general, cartridges have been used, which are charged with comparatively slowly burning or deflagrating charges.
The defiagrating propellants generally used are gelatinized gun-cotton, and in some cases, black powder. The propelling composition is arranged in a cartridge and its defiagration is caused by an initial igniter device or fuse, which contains, for example, fulminate of mercury, lead azide, di-azo-dinitrophenol, and similar substances.
Another groups of substances consists of highly explosive explosives, such as trinitroglycerin, pentaerythritol tetranitrate, trinitrotoluene, picric acid, hexanitro mannitol, and the like, which cannot be used for propelling compositions owing to their explosive detonation. Detonation of such highly explosive materials is initiated by an initial igniter or fuse, i.e. substantially by the same igniting agents which are also used for deflagrating propellants. German Patent 289,017 has disclosed such priming or detonating compositions which contain an active ingredient, as for example, tetrazen. It is further known, for example, from German Patent 518,885, to use as a priming agent, lead trinitro resorcinate, the ignitibility of which is increased very substantially by small additions of A to less than 5% tetrazen. Even small amounts of tetrazen result in an appreciable increase in ignitibility.
Recent investigations have shown that explosives having a nitric acid derivative base, which contain as a priming agent, in mixture, /4 to less than 5% tetrazen, demonstrate an explosive reaction course upon ignition.
For example, if a mixture is prepared of 98% pentrite and 2% tetrazen, and if the same is granulated with acetone and in known manner is formed into pellets having a diameter of 6 mm. and a weight of 0.1 to 0.3 g., it is found that detonation actually occurs upon the percussion priming of said pellets. This is especially apparent if the pellet is used as a propellant in a bolt-setting tool of usual construction in which a propelling composition, in the form of cartridges, is generally employed and is caused to ignite by the blow of a hammer on a riveting set or die. In the case under consideration, the chamber of the bolt-setting apparatus in which the pellet was accommodated was widened to such an extent that a jamming occurred.
It is an object of the invention to provide a composition which is ignited upon percussion and burns in deflagrating manner for use in a bolt-setting tool as a propellant for bolts or the like without causing any damage or distortion of the tool.
It is a further object of the invention to provide a composition of the type set forth above which is completely combustible and which leaves substantially no residue.
It is still a further object of the invention to provide the above composition in the form of self-contained pellets. Moreover, such pellets may be of graduated size for obtaining controlled bolt driving effects.
It is yet another object of the invention to stabilize an explosive nitric acid derivative to enable the latter to be burned in defiagrating manner and by percussion ignition.
The present invention is particularly directed to a process for the driving of anchoring or fastening means into solid and strong materials by means of power operated bolt-setting tools, wherein, according to the invention, propelling compositions, specifically in the form of pellets which burn in defiagrating manner, are ignited by percussion without requiring the use of special igniting agents.
In order to effect such process, it is preferable to use shaped or molded propelling compositions which contain highly explosive explosives of the above-mentioned kind intimately mixed with an amount of tetrazens between 5 to 30 percent by weight, and preferably from about 10 to about 20 percent by weight of the tetrazens in relation to the entire composition of nitric acid derivative and tetrazen. Upon ignition, said propelling compositions surprisingly do not exhibit detonation, but rather, undergo defiagration. Accordingly, the present invention further relates to the preparation of a propelling compo sition with deflagrating characteristics for use in boltsetting tools, said preparation containing the explosive material and a tetrazen compound in the quantitative ratio indicated above.
It has further been found that, upon carrying out the process according to the invention, more particularly upon using propelling compositions of the above-mentioned kind, a burning substantially free of residue is insured within the above-mentioned mixing ranges and that, although tetrazen is known as an igniting agent decomposing without residue, tetrazen contents of, for example, 40% cause the formation of perceptible combus' tion residues and are, at the same time, a considerable olfactory irritant. Depending on the kind and on the quantitative ratio of the respective mixing components, the tetrazens apparently exhibit different kinds of behavior which are unpredictable. Without having to accept any disadvantages, the propelling composition preparation according to the invention can be manufactured in any manner desired and may be prepared in the form of powders, granulates, jellies, plastic compounds, tablets, or other similar commercially available forms. It is understood that the propelling composition preparations according to the invention can be used in any form or shape desired, although another advantage of the propelling compositions according to the invention resides precisely in the fact that they can be used without cartridge cases, as for example, in the form of pellets.
It is understood that envelopes or casings may be pro vided, if desired, which burn practically without residue under the deflagrating reaction conditions of the propelling composition. For example, suitable covering or coating agents may be nitrocellulose lacquers or organic, possibly nitrated, film-forming, monomeric or polymeric compounds, such as paraffins, hard gelatin, natural and/or synthetic waxes or resins, plastics and similar compounds which are known per se and can be selected readily by those skilled in the art.
Especially good results are obtained with pellets in the form of tablets. With or without the use of conventional pelleting or tableting substances, it is possible to use the methods and apparatus generally employed for this purpose for producing such shaped or molded bodies, more particularly, shaped bodies weighing from 50 to 400 mg., and preferably from 80 to 250 mg. Such pellets have in most cases a diameter ranging from about 3 mm. to about 8 mm., and preferably from about 5 to 6 mm.
The composition preparations according to the invention are formed to be particularly favorable insofar that no corrosion phenomena could be observed when they were used.
As regards technical dependability and safety, it is of essential importance for carrying out the present process that the propelling compositions be ignited by percussion only and that they burn without explosion or detonation upon flame ignition. With a view to improving the ignitibility, it is advantageous to place the percussion die not directly on the pellet, but to strike the pellet with a die having finite velocity. The difficult flammability of the propelling compositions at temperatures in excess of about 600 C. also is eflective to counteract accidents.
Another appreciable advantage resides in the ready availability of the substances of the propelling composition as well as the possibility of their use without a cartridge case.
The tetrazen compound contained in the propelling composition preparations according to the invention is advantageously tetrazol-azo-amino-guanidine. Within the scope of the mixture limits indicated above, proportions of about 8 to percent by weight were found to be most advantageous.
There shall now be described by way of example, a propelling composition preparation according to the invention, including the manufacture thereof.
Example 85% by weight pentrite and 15% by weight tetrazen, both in powder form were intimately mixed in a heating dish and were granulated by the addition of acetone. A usual commercial tableting or pelleting press was used to press the resultant powdery mixture in the form of pellets having a diameter of 6 mm. and a weight from 0.1 to 0.3 g. These pellets were used as propellants in a boltsetting tool, in which normally cartridges of different strength were ignited by the blow of a hammer on the riveting die. Instead of said cartridges, the abovedescribed pellets were used and the function of the tool with said propellant pellets was examined to determine the usability of said propellant.
The following factors were considered:
(a) Ignitibility.-The ignition of the pellet by the percussion of the riveting die occurs in dependable manner for all pellets ignited;
(b) Progress of the reaction.-Defiagrating consumption was observed during the ignition, and the pellet is burned without residue. The irritating odor caused by the produced smoke and gases, etc., was less than in the cartridges normally used;
(c) Eficiency (determined by the depth of penetration in a common base 0 the driven bolt).The powder developed by the pellets of the invention correspond to that of the commercially available cartridges. By using pellets of different weights, it is possible to gradate the driving to that obtained by different strength cartridges.
Numerous modifications and variations of the disclosed compositions and processes will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined in the attached claims.
What is claimed is:
1. In a process for driving anchoring devices by a tool, the steps comprising igniting a propellant composition which is defiagrating and which is in pellet form to drive the anchoring devices, the igniting being obtained by percussion, the propellant composition consisting essentially of a mixture of pentaerythritol tetranitrate and tetrazolazo-amino-guanidine, the latter being present in an amount between 5 and 30% by weight of the composition.
2. In the process as claimed in claim 1 wherein the tetrazol-azo-amino-guanidine is present in an amount of 15% by weight.
3. In the process as claimed in claim 1 wherein the terazol-azo-amino-guanidine is present in an amount 10 to 20% by weight.
