PROJECTILE.

PcFATioN forming part of` Letters Patent No. 702,664, dated J' une 17, 1902.

y Application filed November 20, 1901. Serial No. 83,049. (No model.)

To LZZ whom, it ntoty concern:

Be it known Ithat I, AXEL WALLACE MATT- SON, a citizen ofthe United States, residing at 7 Mattson street,Quincy, in thecounty o f Norfolk and State of Massachusetts, haveinvented certain new and useful Improvements in Projectiles; and I 'do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, referencel being hadto the ac-- companying drawings, `and to the figures of reference marked thereon, which form a part of this specification.

This invention relates vto projectiles; and` the primary object thereof is to produce a device of this character which will when discharged leave no residue and shell, obviating any liability of the gun-barrel becoming clogged.

A further object of the invention is toproduce an accelerating projectile of improved construction.

The invention consists in the novel construction of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a vertical longitudinal sectional view of a projectile constructed in accordance with my invention, and Fig. 2'is a perspective view of the frame thereof.

l designates a metallic head provided with an annular ange 2, a central channeled collar 3, and a fulminate 4.

5 designates a cylinder adapted to carry a charge of rapid-burning powder and is constructed of any suitable material and provided on the periphery thereof with a suitable number of radial arms or lugs 6. The cylinder is perforated at intervals throughout its entire length, as at 7, and one end thereof is closed andsolid fora portion of its length, as illustrated -in Fig. 1 of the drawings, and the opposite end thereof is open and detachably secured in the channel of the collar 3, thus forming a frame for the reception of the materials constituting a projectile. Said cylinder will when the projectile is discharged break away from the head 1, leaving the gun-barrel free of residue and shells.

8 designates a point having a reduced portion 9 and a central recess 10, which receives the solid end of the cylinder 5, to which said projectile is secured.

11 designates a charge of smokeless powder,

.which is compressed upon the frame and varound ihereduced portion 9 of the point S infany desired manner, and the arms 6 being embedded therein serve to hold it against casual dislodgment.

If desired, the cylinder of compressed powder may be Wrapped with a very thin sheet of isinglass, which affords a protection to the powder.

The utility and operation of the device may be explained as follows The parts being assembled, asillustrated in Fig. l of the drawings, by igniting the rapid-burning powder carried by the cylinder 5 through the medium of the fulminate 4 the smokeless powder is simultaneously ignited at different portions of its entire length through the perforations 7 in the cylinder 5, and upon the explosion of the cartridge the point 8 will be discharged from the gun, breaking or withdrawing the frame from its fastening in the collar 3.

It is obvious from the foregoing description, taken in connection with the accompanying drawings, that I produce a projectile which will when discharged leave the gunbarrel free from residue and shells.

Having described my invention, what I claim isl. A projectile comprising a firing-head, a stem projecting from the firing-head, and formed with radially extending lugs, arranged at intervals, and a point carried by the inner end of the stem, and a charge of powder surrounding the stem and having the lugs embedded therein.

2. A project-ile comprising a firing-head, a cylinder carrying a charge of rapid-burning powder and projecting from the firing-head, and formed with radially-extending lugs arranged at'intervals, and a point carried by the inner end of the cylinder, and a charge of smokeless powder surrounding the cylinder and having the lugs embedded therein.

3. A projectile comprising a firing-head provided with an annular' flange and a channeled collar, a cylinder carrying a charge of rapid-burning powder, and perforated at intervals throughout itsy entire length, and

IOO

formed with radially extending lugs arranged yat intervals, one end of said cylinder being open and detachably secured in the channel ot' said collar, and a point carried by the inner end of said cylinder, and a charge of smokeless powder surrounding the cylinder and having the lugs embedded therein.

4. A projectile comprising a firing-head provided with an annular flange and a channeled collar, a cylinder carrying a charge of rapid-burning powder, and perforated at intervals throughout its entire length, and formed with radiallyextending lugs arranged at intervals, one end of said cylinder being closed and solid for a portion of its In testimony whereof I affix my signature in presence of two witnesses.
