still a further Object of the invention is to provide a safety catch of the aforedescribed character of extremely simple construction and which is capable of being economically manufactured and sold, so that the destruction of the catch, upon detonation "of the charge, will not represent a material loss.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating the preferred embodiment thereof, wherein:
Figure 1 is a side elevational view showing the catch in operative position applied to an explosive charge and positioned for supporting the charge in a tube or conduit;
Figure 2 is a side elevational View of the catch shown applied to an explosive charge and taken substantially at a right angle to Figure 1;
Figure 3 is a cross sectional view taken substantially along the plane as indicated by the line 33 of Figure 1;
Figure 4 is a fragmentary plan View of one end of the charge embracing a portion of the catch, and
Figure 5 is an end view in elevation of a retaining keeper of the charge embracing member.
Referring more specifically to the drawing, the safety catch or anchoring member in its entirety is designated generally 6 and comprises an elongated strap 1 formed of sheet metal or the like which is provided with a restricted tongue 8 at one end thereof and a transversely disposed slot 9, adjacent its opposite end. The strap or encompassing member 1 is adapted to extend around a portion of the enclosing sleeve H] which forms a container for an explosive charge I l and the tongue 8 is passed outwardly through the slot 9 and turned back upon itself to overlie the end of the strap 1 from which said tongue 8 projects, as seen in Figure 1. The tongue 8, before being right angles to the plane of the arcuate portion turned back upon itself, as previously described, is drawn through the slot 9 sufliciently so that the strap 1 will engage relatively tight around the sleeve 10. The portion of the end of the strap 1, which is engaged by the turned back end of the tongue 8, carries a keeper l2'which isllikewise formed of a relatively narrow strip of sheet metal. The intermediate portion of the keeper l2; as seen in Figures 1 and 2, is disposed over a portion of the outer side of the strap 1 and over a part of the'turned back end of the tongue 8 and transversely of said part. The ends I3 of the keeper 12 are turned inwardly and backupon themselves" and are disposed beneath a portion'of the strap l and are retained, thus positioned, by being clamped between said portion of the strap 1 and the sleeve Ill. The intermediateportionlof the keeper [2 engages the tongue 8 sufficiently close to prevent the turned back portion of the tongue sliding relatively thereto, so as to retain the strap or belt 1 in an applied position around the ,encasing sleeve 10. To prevent sliding movement of the applied strap 1 relatively to the sleeve [0, said strap is provided at circumferentially spaced'intervals with pairs of prongs [4 which are struck inwardly from the body of the strap 1 and, each of which is substantially V-shaped. The individual prongs M of each pair of prongs, are transversely spaced and the tapered pointed ends' thereof, before being struck inwardly, extend toward one another. The inwardly struck prongs [4 are embedded in the sleeve [0 and may extend slightly into the charge II for securely anchoring the strap 1 to prevent it from sliding relatively to said sleeve l0.
As best seen in Figure 3, the strap or encircling belt l is provided with substantially diametrically opposed outwardly extending arcuate portions [5. The catch 6 also includes a strand of relatively heavy gauge, resilient wire, designated generally l6 having an arcuate intermediate portion I! which extends substantially half-way around the sleeve I0 and beneath the strap 1 and the ends of which terminate in upwardly extending legpor'tions 98, which are disposed substantially at H and which extends through the strap portions l5 to'be clamped thereby against portions of the sleeve Hi. The legportions l8, directly above the upper edge of the strap 1, are provided with out wardly extending portions I9 which engage over the upper edges of the portions !5 to prevent downward sliding movement of the leg portions I8 relatively to said portions IS. The terminals or legs 28 of the wire strand l6 project upwardly in diverging relationship to one another from the outwardly extending portions [9 and terminate at their free ends in outturned terminals 2! which are adapted to frictionally and yieldably engage the inner surface of the wall of a tube or conduit 22 in which the explosive charge I 0, H and the safety catch 6 is disposed. As clearly illustrated in Figurel, it will be readily apparent that the catch 6 will normally support the explosive charge within the tube 22 and substantially concentric therewith.
It will be readily apparent that the explosive charge with the safety catch 6 applied thereto may be forced downwardly in the tubing 22 by any suitable and conventional meansjnot shown,
and the resiliency of the legs 20 will permit the terminals 2| thereof to slide relatively to, the tubing wall while the charge is thus bein-gjforced downwardly in the tubing. However, the legs 20 arecof sufiicient strength to resiliently retain the pterminalsZ-l in frictional engagement with the wall of thettubingZZ so as'to support-the charge 'in any position to 'whichit is moved and when-a 'force'is no longerbein-g exerted thereon to force the charge "downwardly.
Obviously, the size of the safety catch 6, including the length of the strap -1 and the length, gauge and resiliency of the strand I6 may be varied'to accommodate charges-of different sizes *and to provide legs 20 of 'sufiicient streng-th for supportingcharges-of differentweights. Various :other modifications and changes are likewise contemplated and may obviously be resorted to, without departing from the spirit and scope of the invention as hereinafter defined lby the ap- -pended claim. 1
* We claim:
In combination with an. explosivecharge enclosing sleeve, a spring support mounted on the sleeve and adapted to support it in a vertical conduit, said spring support including a resilient strand and a sleeve encircling metal strap securing the strand to the sleeve, said strap having fastening means adjustably connecting the ends thereof and securing the strap around the sleeve, inwardly extending prongs struck from the strap andembedded in the sleeve,.said strap having oppositely disposed outwardly offset-portions, said strand having an arcuate intermediate portion engaging partially around the sleeve below the strap, said arcuate intermediate portion terminating in upwardly extending leg portions disposed "betweenthe sleeve and the outwardly ofifset portions of the strap, said strand having cor- ,turned terminals-into frictional engagement .with the wall of the conduit to support the chargeenclosing sleeve .in the .conduit.
