KATZ EXPLOSIVE DEVICE AND THE LIKE Filed May 24, 1929 Patented Feb. 16, EQSZ EUGEI N K ATZ, OF IBEBLIN-CHARLOTTENBURG, GERMANY, ASSIGNOR TO KEYES CON- TAINER COREORATION, F BOSTON, MASSACHUSETTS, A CORPORATION OF mnosrvn nnvrcn AND THE LIKE Application filed May 24, 1929, Serial No.
poses.
Such devices require complete exclusion of moisture and must be gas proof and otherwise generally impermeable for which reason integrality is of the highest desirability as 19 joints of any nature introduce factors of leakage and difficulty. i To this end I contemplate articles for the specified purposes capable of adaptation to varied requirement and free from joints or 5 seams and of characteristics adaptable to a wide range of requirement.
I provide by my concept a new materlal orbasis of fabrication for such articles which makes possible the manufacture of a variety a of these requirements in new and newly functioning forms. 7
To produce hollow articles of this class or dinary requirements involve not only the jointless, seamless thing to be used, but other physical factors by reason of which composite articles have had to be used as ior example, metal, wood, paper and other equally difierent materials. There are requlred 1n these articlessuch extremes asgas and water proofso ness and mechanical strength-and machinework adaptability as for turning, threading, drilling or grinding.
Such is in contra-distinction to previous structures andmaterials, such as wrapped paper cases and sheet metal combinations; As distinguished from wrapped paper and like bases of fabrication, my concept provides for an impregnation basis by which characteristics are developed which lend themselves tothe previously stated desiderata of impermeability and mechanical workings. l
As illustr tive I will describecharacteristic examples of'the utility of my inv'ention as in the accompanying drawings in which I Fig. 1 is a partly sectioned view of hand grenade, the charge and ignition device being omitted, and
Fig. 2 a partly sectioned view of a cartridge case.
510 These devices well illustrate the combined tured as at a and 365,708, and in Germany May 29,1228.
requirement heretofore met only with great difiiculty and at high cost.
The grcnadecasing shown in Fig. 1 is formed of fibre pulp wet laid in a hollow die to form the seamless enclosing wall a aperprovided with a sleeve like extension a a I Such a body is impregnated with an asphaltic, pitch-like or gummy penetrant which permeates the fibrous wall and converts the soft and generally porous body into a damp and gas proof member. In addition to this it makes of the fibre body a cohesive article capable of submission to tooling operations such as turning, threading, drilling and like machine work where the casing a' must be prepared to tightly receive a fitting such as the threaded end I) of the handle I). To this end the collar a may be cut with an internal thread and so worked without crumbling or cracking the material.
Where such articles are so machined I preferably re-coat the surface with the original or a like impregnating compound, and this may be advantageously accomplished at the tigne ofthe'assembly of the handle I) as it' then constitutes also a cementitious seal. In such assembly a gasket as g may be used to furthe plosivtgchamber.
' The shell casing shown in Fig. 2 illustrates a similar problem but of slightly different character. Here we have a cylindrical wall insure the complete sealing of the exb 0 with flanged head d capable of receiving v the metallic driving band 6. The shell wall 0 and head d are wet laid pulp as described andare as such' integraland homogeneous in character of'material, but moulded for" thickness.
Such a moulded pulp shell'is then impregnated as before described, and may be turned to accurate grooved to receive the metallic band e. It may be also drilled and tapped as at of for the desired ahead flange and reinforcing diameter and threaded or V its ignition member, the machined parts being re surfacedkor described, w
Such an article'as the shell casing of Fig. 2 represents a problem of extreme requireimpregnated as before lot ments of accuracy. As a composite shel=l casing it, meets practical ordinance requirements and as an integral explosive casing it has a lightness and impermeability impossible in any previous composite or combined material shell or cartridge casing.
Such articles may have in addition to their impregnation coatings of metal, enamel, varnish or lubricative substances to give added protection as desired.
What I therefore claim and desire to secure by Letters Patent is 1. In a grenade, a gas and damp-proof chamber comprising a relatively thin enclosing Wall of impregnated fibre of toolable coherency and having a relatively small neck having an internally threaded aperture, and
. a threaded attached member engaged therein and sealed thereto by a bonding material of impregnated character to reimpregnate the neck threads and bond the thread interengagement, said attached member having a shoulder above its threads and engaged with the neck and sealed thereto;
2. lIhe device of claim 1 in which the attached member is a handle of material permeable to the sealing material.
3. In a device of the character described, 7
including a gas .and'damp-proof chamber comprising a relatively thin enclosing well of impregnated fibre of toolable coherency and havmg a relatively small'neck having an internally threaded aperture, and a threaded attached member sealed thereto by a bonding material of impregnating character and itself permeable to such sealing ma.-
terial whereby the thread engagement is sealed and the neck threads reimpreated.
