To all 'whom t may concern:

Be it known that LYJAY H. WooLHisnR, a citizen of the United States, and a resident of Elmhurst, county of Queens, city and State of New York, have invented new and useful improvements in Favors, of which the following is a specification.r

rlhis invention relates to socalled snapping favors and themethod Lof making the same.

These devices consist primarily of a roll of fancy paper containing a paper cap or similar favor or souvenir, and a small quantity of explosive arranged to be ignited upon pulling the ends of the roll of paper apart. As heretofore manufactured, the exploding device of the snapper consisted of two overlapped strips of cloth or paper, the overlapped ends of which were provided with a mixture of a fulminating compound, a suitable adhesive and sandor other abrasive, the ends of the strips being arranged so that when -the ends of the snapper were pulled apart the coated ends will be drawn over each other with a resulting explosion.

These devices, while more or less satisfactory in use, presented serious diiiiculties in manufacture by reason of the highly explosive nature of the material used which rendered the handling of large batches of it, particularly Vwhen mixing it with the sand, extremely hazardous, and accidents in the making of the snappers, particularly in spreading of the explosive upon the paper strips, were quite frequent.

rlhe primary object of my invention is to provide an improved snapper which may be manufactured cheaply in large quantities and without the danger heretofore unavoidable.

A further object of the invention is to provide a snapper in which a small quantity of explosive compound, which is more or less expensive, will produce a detonation of the same intensity and with greater certainty of ring whenever the ends of the snapper are pulled. y

A further object of the invention is to provide a method of making the snappers whereby the preparation ofthe paper strips and the application thereto of the explosive mixture and sand will be carried out in large numbers of strips at a time, confining the yhandling of the individual snappers to the mere assembling, thereby greatly reducing the manufacturing cost,

Specification of Letters Patent.

Serial No. 245,639.

Further objects of the invention will appear from the following description, taken in connection with the accompanying drawings, wherein l have illustrated two different forms of my improved snapper and the different steps in its manufacture.

in said drawings,

Figures 1,2 and indicate three successive steps in the preparation of the paper strips of which the snapping devices are made;

Fig. l is a cross sectional view on an enn `modified mode of procedure;

Fig. 9 is a plan view` showing the cardboard strip on the favor as employed in this modified form;

Fig. 10 is a perspective view showing the method of assembling the paper strip in the pasteboard core; and

F ig. 1l is a detail view showing the relative positions of the explosivecompound and the sand after the strip is assembled in place.

According to my improved method of manufacture, l take a strip of tough paper about three and one-half or four inches in length, as indicated in llT ig. l, and slit it transversely of its length from one edge almost te the other, making a series' of individual tongues 2 about one-eighth to a quarter of an inch in width, connected'along one end by the narrow uncut margin 3 of the paper web. The slitting of the paper may be economically accomplished by an ordinary paper shearing machine .adjusted yto cut not quite across the width of the web. After the paper is slit, l apply along the edge of the web forming the free ends of the strip a line of glue into which is sprinkled while still soft, a layer of sand, as indicated at 4, forming a striking surface similar to that applied to match boxes for ordinary matches.

lf the paper is 'in a continuous web the sand and glue may be applied by a sanding machine such as used in the manufacture of match boxes. If the method is carried out largely by hand, the paper web will rst be cut in sheets of a length convenient to handle, say four or five inches long, and the glue and sand can then be applied with a brush and sprinkler.

After the sand is applied, the explosive compound or dope which consists preferably of a mixture of fulminate of silver and flour paste, is applied to the edge of the slit web in a line adjacent the sanded surface, as shown at 5 in Fig. 3. This mixture is very easily exploded during the mixing and while applying to the paper strips. It is therefore essential thaty it be handled by skilled labor. i

By my improved method of manufacture the fulminate is mixed with the paste, and While sufficiently soft to flow readily the operator takes a small trough or funnel 6, preferably of stiff paper, and scoops up enough of the material for a sheet of the paper web and then draws the funnel along over the web just out of contact with its surface rapidly enough for the iiow of the dope from the end ofthe funnel to leave the desired size streak on the paper. This operation occupies but a few moments for each sheet, which will be long enough for several hundred individual paper strips or tongues. After the paste hardens thevmaterial is no longer so Vexplosive and the individual tongues may be torn apart and assembled without danger even by comparatively unskilled labor.

To complete the snapper two of the individual tongues will be detached from the web by breaking apart the glue and dried dope at the free end and tearing the paper along the margin 3, and the .two strips will then be overlapped in the relative positions shown in Fig. 4, that is, with their prepared faces together and sufficiently overlapped for the particle 7 of compound and the attached bit of sand 8 of the left hand strip to lie to the right of the sand and compound of the right strip, so that when the strips are pulled apart the bit of compound on one strip will be dragged over the sand on the other and simultaneously the bit of compound on the second strip will be drawn over the sand 0f the lirst, causing a simultaneous explosion of both. The ends of the strips may be held together in overlapped `relation in various ways.

My preferred method as disclosed in the drawings consists in wrapping the overlapped ends with several turns of light paper, the free end of the wrapping paper being glued to the underlying turn of the other strip.

favors usually consist of a short cylinder of cardboard, as indicated at 9, about two and one half or three inches long, in which is stuffed the confection, souvenir, etc. The assembled paper strips are held against one wall of the cylinder with the free ends projecting beyond the ends of the cylinder and the two are then wrapped with several turns of fancy paper, as indicated at l0, the fancy paper being slightly greater` in width and length than the assembled strips so as toV conceal the endsof the strips. The end of the fancy paper' is then bunched' together either by twisting or binding, as indicated at 11,

with the ends of paper strips held in the bunched end so that when the ends are grasped to be pulled apart the Vends of the two paper strips will be gripped suiiiciently for their treated endsY to be drawn past each other, thereby exploding the dope My improved favor presents 'several advantages over those previously used. In the first place, it is much more certain of operation, due to the fact that when the sand is mixed directly with the dope the particles of sand which will project above the dope mixed with the binder may prevent suiiicient scratching of the explosive compound to y detonate it, while with my improved snapper the free dope unmixed with the sand will invariably be drawn across the sand of the In the manufacture of the vold style favors there is also danger of exploding the batch of dope when mixing the sand with it, due to the more explosive condition of the dope and the liability of creating suiiicient friction to ignite it by the mixing in of the sand. Also, it would not be Safe to apply the sand mixed with the dope to the edge of a web or sheet of previously cut tongues for the reason that the breaking apart of the tongues would be likely to cause an explosion of the mixed sand and dope so that the individual narrow strips had to be separately dipped or coated with the mix ture.

In my improved snapper the dope7 does not come in Contact withk the sand until it has exploded, and the breaking apart 0f the separate tongues after the dope is dried will not cause an explosion because there is no abrasive material mixed with it.

I also use less. dope in my'improved snapper than in the old style, for the reason that it is necessary to have the stripe of sand of sufficient width to insure the explosion of the compound when drawn over it. When the sand is mixed'with the dope the width of the strip of do e is coextensive with that of the sand.V y applying the dope and sand separately, the sand may be of any desired width to yinsure explosion before the particle of dope willvbe drawn completely across its 'entire Width, but the particle of dope may be no larger than necessary to give the desired sound.

In Figs. 7 to 11, inclusive, I have illustrated a modified form` of my improved snapper in which the process of manufacture is simplified and also the cost of materials is lessened. T0 produce the snapper here shown I proceed to first cut the paper web in the same manner as heretofore as indicated in Fig. 7 into a series of tongues 2 joined along one edge by an uncut narrow margin 3 of the web. I do not, however, apply sand to the ends of the tongues, but apply the stripe of dope7 5 in the manner heretofore described, along the cut edge of the web, so that each tongue when separated from the web will be provided with a small particle of the dope The sand for igniting the dope is applied in a larger spot 15 to the surface of the sheet of pasteboard 9 out of which the body of the favor is made, the sand being preferably along the side of the stripe of adhesive 16 by means of which the pasteboard is secured in roll form. The sand may be easily applied by daubing a spot of glue on the face of the pastboard and dusting it with sand.

After the glue is dried, one of the tongues 2 separated from the web and carrying the dried particle of d0pe, will be led over the spot of sand with the clean end of the tongue projecting beyond the margin of the sheet 9 and the end carrying the dope beyond the spot of sand, as illustrated in Fig. 1l. With the tongue so held the strip 9, is rolled into tubular form, as shown in Fig. 10 and the glued margin 16 attached to the adjacent face of the sheet, so that the strip will be held in place between the lapped ends of the roll. 'Ihe gift or souvenir will then be placed in the roll in the usual manner and the roll covered with the usual fancy paper covering 10 as indicated in broken lines, which will be completed in the manner heretofore described.

In this form of snapper only one tongue is used and the step of attaching the tongues together is avoided, but the snapper produced is not so certain in its action as the first described form, for the reason that the paper at the end of the tube opposite the location of the firing strip may be pulled off before the strip is drawn across the sand, while in the preferred construction the free ends of the lapped strip are positively gripped and the ring will take place however the paper may tear.

I claim:

l. The method of making firing strips for articles of the class described which consists in slitting a web of paper transversely into strips and then applying to the paper while the strips are still positioned as in the original web a stripe of abrasive material and a stripe of explosive material separated from the abrasive material, the stripes extending transversely of the strips and longitudinally of the web.

2. The method of making firing strips for articles of the class described which consists in slitting a web of paper transversely into strips extending almost the width of the paper and leaving an unslit margin of the web connecting the strips at one end, applying to the other end separate stripes of abrasive material and explosive material, re-

spectively, the stripes extending transversely of the strips and longitudinally of the web, and thereafter separating the strips one from the other.

3. The method of making firing strips for articles of the class described which consists in transversely slitting a web of paper at closely spaced intervals to divide the web into narrow tongues held together along one edge of the web, applying to the slit edge of the web a stripe of sand, thereafter applying to the web a stripe of explosive compound extending parallel to the stripe of sand but spaced therefrom by moving a container from which the semi-liquid explosive compound is flowing longitudinally of the web, then allowing said explosive compound to dry and thereafter separating the individual narrow strips from each other.

Signed at Elmhurst in the county of Queens and State of New York this 3rd day of June, 1918.
