SEE-CIFEGATQN forming wart o1" Iietters Patent No. 681,091, dated August 20, 1901. Application lcd April ll, 190i. Serial No. 55,405. (No model.) y

To LZZ 'iv/bom. it may concern:

Be it known that I, @Hannes ELLsu'oRTn ADAMSON, a citizen of the United States, re siding at Muncie, in thecounty of Delaware and State of Indiana, have invented a new and useful Lubricating' Giin-ilfad, of which the following is a speciiication.

ylhis invention relates to a lubricating guuwad wherein the wad is formed of two or more 1c lubricating,r materials heated together in couinonuding, so as to become hard when c old, and which will become serniliquid when subjected to heat.

lihe primary object of the invention is to provide a lubricatingwad Jwhich in its normal condition is sufficiently solid or hard to admit it to be used an interior or exterior wad, the ingredients and consistency of the wad to be such as to be broken up into fragso ments by the explosion ol' the shell and to become melted into a lubricating seiiiiliquid lfrom the heat in the gun-barrel. "ihcsc and other objects not hcreinbcroro srentioned are accomplished bythe compound 'escribcd and bythe construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding paris in boi-.h views,- and in .i'hiohl a perspective View or' one oi' my fis det cheri from the cai dgn; and Fig. 2 is aseo i h a c;- 'tric go, showing my wad in nosition in iront o the shot to be used as an exterior wad. y

l have only shown one position of wad in the cartridge, as it is obvious that the position can be changed indefinitely in the A designates the brass base, in which the paper shell i3 is secured inl the usual manner. C designates the cap; l), the powder; E, the card wad over the powder 3 F, the felt wadsgG, the shot; il, my iiuproved outer or exterior wad, and the usual crimp forvholding'the Wad in the cartridge.

in compounding thev material for the wad f5.5 l use as a base powdered graphite, which. l nii): with hot melted parailin until it becomes thier: paste, the :proportions or" each being about one pound oi graphit-e 'to about six ounces of parallin, or i und it somewhat iin- 5o proves the compound by using i'our ounces of paraffin and two ounces or" spermaceti, the latter being more hard and brittle than the parafiin and about the same lubricant, but more expensive. he graphite is mixed inthe hot melted paralliu or liquid and then rolled into 5 5 sheets of the desired thickness to make a gun-` 4 wad, then cut or stamped out into little round dat disks like shown in-Fig. 1, the diameter;- of the Wade being made to suit the different gages of guns or shells. The cutting orform- 6o ing of the disks is done While the material is yet warm to prevent them from breaking upa As soon esilio wads become cold they are ready for use or for being packed up in boxes for shipments. 65

It is well known that a gun-barrel becomes heated by being discharged a number of times in succession, and that in so doing a portion oi the residue from the burned powder adheres v i to the dry barrel and becomes baked thereon. ','joY Then after getting in this condition the barrel will begin to iead, which is a natural result from the friction on the shot while be# ing vforced over the dry crusty places in the. barrel. t is also Well known 'that when a ruilhandel becomes highly heated that it wilt lead uncss kept moist and lubricated, as hereiu described.

l have found by experiments that a `gunhariel must beV provided with a lubricant that 8o has a sui'iicient amount of oil to prevent the Jai-rel from becoming dry; The intense heal, tends to dry' and bake the residue from the Ypowder in the barrel, and by combining;` a

fusible oily lubricant with a powdered non- `85 combustible lubricant the moist lubrication is obtained from one ingredient and the com;lv bustion of this moist lubricant preventedby the other ingredient.

By the use of, my compound I am abley to 9o.. retain the normal smooth condition.A of the barrel at all times, as the semiliquid lubrica-l tion takes piace and is supplied at each-'dis' charge of a shell.- y

i' do not confine myself to the exact mail@ 95 .rial or the proportionsset forth, as I ma find. other combinations of a non-combustible and, scmiliquid or liquid lubrication that will pi j duce the desired cfiect. Nor do lconnglny soif to making the entire wad 'of'. the comol :om

pouucl, as it is obvious that an ordinary Wad could loeutraly coztted with the compound or only have its edges abated.

l. A lubricating compound for gumwads consisting of 'a fusible amil a non-combustible material eompnuuc'le together so as to be come hard in its normal condition.
