BLASTING SHELL.
Application. filed March 15, 1921, Serial N'o. 452,405. Renewed January 9, 1923.
To all whom it may concern.
Be it known that I, GEORGE S. CLARK, a
citizen of the United States, residing. at
Bowling Green, in the county of Warren and State of Kentucky, have invented certain new and useful Improvements in Blasting- Shells; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same; I
In mining operations the best results are.
attainable by the use of a shell of proper size both as to diameter and length.
The present invention; provides a shell in aflattened form for convenience of storing and handling and embodying a plurality of I sizes formed by longitudinal folds or crimps which normally are confined by a sealing strip,' one or more of the folds or crimps being releasable by severance of the sealing strip, whereby to provide a shell of required size said sealing strip also serving to conwithout measuring or having recourse to nect the'longitudinal edge portions of the shell forming strip;
Theinventijon also aims to provide a shell of the character aforesaid which admits of the required length being readily obtained by releasing longitudinal folds or crimps.
In the latter case they tube will be of minimumdiameter and embody confined folds or crimps which are released to provide the shell of required'diameter.
The'invention also aims to provide a tube embodying sealing-means which may be in the formof a continuous linear strip, or aplurality of transverse strips. The linear strip in one form includes marginal tabs for confiningthe'reducing folds and the transverse strips in one embodiment have end portions free to serve as fold securing means.
Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.
While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.
Referring to the accompanying drawings forming a part of the specification,
Figure 1 is a perspective View of the blasting ,tube in packet form,
Figure :2 is a detail perspective view of a portion of the tube having a longitudinal edge portionfolded and secured,
Figure 3 is a perspective view of a modification in which the linear sealing strip is provided along opposite longitudinal edges with marginal tabs,
Figure 4: is a perspective View of the form of tube shown in Figure 3, having opposite edge portions folded and made secure,
Figure 5 is a further modification showing transverse sealing strips,
Figure 6 is a further modification showing opposite ends of the transverse strips loose and adapted to secure opposite folded edge portions of the tube,
Figure 7 is a perspective view of a differ ent form of tube reduced to packet form and embodying longitudinal crimps,
Figure 8 is a transverse section of the form of tube illustrated in Figure 7,
Figure 9 is a'further modification showing a strand for severing the sealing strip,
Figure 11 is a view similar to Figure 10 with the size fold released and extended.
Figure 12 is a perspective view of a fur ther modification in packet form,
Figure 13 is a transverse section of the form of tube shown in Figure '12 having one of the size folds released and extended,
Figure 14 is a view similar to Figure 13 having all the sizefolds released and 6X1 tended,
Figure 15 1s a further modification showsecure and co:
venience of handling. The shell is formed from'a strip 1 of paper or other suitable sheet material sz id strip being of any desired length and width. in the format-ion of the shell or tube, the longitudinal edge portions of the strip 1 are brought together and preferably overlapped and secured in any preferred way. Portions of the tube or shell thus formed may be longitudinally folded'or crimped, the folds being designated at 2 and the crimp's at The number of longitur'iinal folds 2 or crimps 3 will depend upon the range of adjustment of the tube or shell to meet predetermined requirements. The folds or crimps may occupy any relative position in the *idth of the tube, as will be readily understood.
Longitudinal edgeportions of the tube 'or'shell forming strip 1 and the several size forming folds 2 and. crimps 3 are made fined by means of a scaling strip, the latter being applied in such manner as to overlap the joints and made secure by a suitable adhesive. The tube or shell in its initial form is of a determinate size which may be maximum or minimum. mum size and a larger sized tube or shell is required, one of the folds 20 n crimps 3' is released and opened out with the result that the diameter of the resultant tube or shell is increased by the amount contained in the size fold or crimp released. If a tube or shell of still larger diameteris required another size fold or crimp 'isrelea'sedand extended, and so on for each sizefold 0r crimp within the range of adjustment of the tube or shell. For convenience of severance of the scaling strip l along a fold line, a strand may be provider. and disposed beneath the sealing strip adjacent the fold line of the size fold to be released. Another way of facilitating the severance of the sealing strip the provision of a weak,- ened line 6 which may be formed by closely related perforations in a'manncr well under stood in the paper manufacture art. The size folds or crimps may be released in any desired or preferred way by severance of the sealing strip along the fold lines. It will be understood that the strip 4 serves both to seal the tube or shell and to confine the several size folds or crimps.
In the form of tube including confined If of mini size folds or crimps, the sealing means may consist of a continuous linear strip {l or a plurality of transverse strips et \Vhen the tube is of the form requiring release of the size folds or crimps to increase the diameter of the tube the confinin or sealin stri s tabs 7' which normally are free and supplied 7 With an adhesive, the latter being moistened preliminary to pressing'the tabs 7' upon the folds or crimps for securance' thereof. lVhen the transverse strips are employed, one or both end portions of such strips are loose, whereby they may beu-tilized in the capacity of the tabs 7 and in alike manner for securing the folds or crimps when the diameter of the tube is reduced by folding or crimping longitudinal portions thereof. To facilitate the folding or crimping of the tube, the same is provided with one or more lines of perforations 8 whichserve both as guide means as Well as facilitating the fold: ing or crimpingof the tube.
In the preferred marketable form, a given length of tube is reduced to the form of a packet by reversely folding the same, as indicated at 9, the folds being of uniform and predeterminate length whereby a shell of required length may be quickly obtained by extending one or more of the folds 9 as may be required.- The linear folds 9 enable the length of the tube to be reduced to convenient form and also serve as guide means when separating a portion of the tube to provide a shell of required lengtln The linear folds 9 may be siX, eight orften inches in. length more or less as may be determined upon." If the folds'9; are eight inches'in length and it be required to form a'shell eight inches long, a portion of the tube issevcred from the packet corresponding to the length of one of the folds." However, should the shell required be sixteen inches in. length, a portion of the tube is removed corresponding tofthe combined length of two of the folds. The length of the folds being known, a shell of required length may be readily formed by separatmgaportion of the tube from the" packet, the length being approximately determined by referenceto the folds and sectional parts thereof, asiwill be readily understood.
The tube in packet form is-compact and may be readily handled and supplies the V quired length and diameter may be readilyminer with an article whereby a shell of reformed and when completed, may be handled without spreading or buckling which are serious objections to the successful use of the ordinary shell.
l/Vhat is claimed is:
1. As a new article of manufacture, a multiple blasting shell or tube comprising a plurality of independently confined size folds or crimps whereby to provide a shell of required diameter by releasing and extending one or more of the size folds or crimps.
-2. A multiple blasting shell or tube embodying a plurality of size folds or crimps, and independent means normally confining each of said foldsand overlapping and sep arable in line with the joints thereof, whereby to provide a shell of given diameter, said shell being adapted for diametric enlargement by releasing'one or more of said size folds.
3-. A multiple blasting shell or tube embodying a plurality of size folds or crimps, and a sealing strip for confining the size folds or crimps and adapted for severance to release the size folds or crimps to admit of enlarging the shell or tube to meet existing requirements.
4. A multiple blasting shell or tube consistingof a strip having its longitudinal edges brought together and an intermediate portion folded, and a sealing strip for securing the size fold and the longitudinal edges of the shell forming strip.
5. A multiple shell or tube for blasting purposes consisting of a strip having its longitudinal edges brought together and overlapped, and having portions upon opposite sides of the joint thus formed folded to provide size folds and a sealing strip for securing the size folds and the edges of the shell forming strip.
6. A blasting tube consisting of a strip having its longitudinal edges brought together, a sealing strip securing the brought together edges and having loose portions for confining portions of the tube when folded to reduce thediameter thereof.
7. A blasting tube having longitudinal weakened lines to designate folds for reducing the diameter of the tube, and having its longitudinal edges brought together, and a sealing strip securing the brought together edges of the tube-forming strip and having loose portions for confining the reducing folds.
