SPECIFICATION forming part of vLetters :Patent No. 707,913, dated August 26, 1902.
Application liled April 12, 1902. Serial No. 102,552. (No model.)
To @ZZ whom, it Nif/,ty concern:
Be it known that I, GEORGE HENRY GARRI- sON, a citizen of the United States, and a resident of Bucoda, in the countyof Thurston and' State of Vashington, have invented a new and Improved Gun-Cleaner, of which the following is a full, clear, and exact description.
This invention relates to improvements in devices for cleaning the interior of gun-barrels, the object being to provide a simple means for expanding the swab while operating in a gun-barrel.
I will describeagun-cleanerembodying my invention and then point out the novel features in the appended claims. n
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters ol reference indicate corresponding parts in all the figures.
Figure 1 is a` side elevation, partly in section, of a gun-cleaner embodying my invention. Figs. 2 and 3 are sectional details showing different positions of the swab. Fig. 4: is a section showinga modiiication. Fig. 5 is a section on theline am of Fig. 2, and Fig. 6 is a section showing another modification.
The cleaner comprises a tubular handle, preferably consisting of sections 5 6, having screw-thread engagement one with `the other. Movable in the rod lor handle 5 6 isa pushrod consistingof two sections 7` 8, which at the lower end is engaged by an operating-lever 9. Movable on the end of the rod isa sleeve 10, which has connected to it a pin 11, the said pin extending through opposite slots 12 in the rod. Extended from the end of the rod-section 8 and through an opening in a disk 13, mounted loosely on the end of the sleeve 10, is a core 11h-which is verlnicularin form. Mounted on this core is the swab, consisting of a series of disks 15, formed of metal fabric. The core 11i also extends through an opening in a disk 16 on the outer end of the swab, and between the said disk 16 and the head 17 on the coreis a coiledspring 18.171? The core 14, especially the portion thereof within the swab, is made resilient, so as to slightly yield or expand during the movements of the swab througha gun -barrel, permitting the swab to pass obstructions-such, for instance, as lead or hard burned powder.
ln the operation of this device when the swab is inserted the lever 9 is to be operated, so that the inner rod will force the sleeve 10 outward, consequently compressing the swab material longitudinally of the core. By this compression and owing to the shape of the core the swab will be circumferentially expanded by moving the component parts out of alinement, as indicated in Fig. 3.
1n Fig. 4l have shown the vermicular core 19 as provided at one end with athread 2O to receive the interior thread of a sleeve 2l. On the end of this sleeve is a disk 22, having an opening through which the core passes, and on this disk one end of the swab 23 rests, the other end of` the swab engaging with a disk 24, having an opening through which the core passes, and between this disk 24 and the head 25 on the end of thecore is a spring 2 A cord 27 is connected to an eye 2S on the end of the core, and connected to an eye on the end of the sleeve 21 is another cord 29. By means of these cords the swab may be drawn back and forth through a gun-barrel, and, obviously, the swab may be adjusted to the bore ofthe gun. by turning the sleeve 21, which compresses the swab material, on the core. This core also will be` made resilient for the purpose before described..
In Fig. 6 I have shown a device somewhat similar to that of Fig. 4; but the core 30 is flat and sleeves 31 are engaged with each end of it. By drawing tightly on the two cords the core will be extended and the diameter of the swab will be reduced.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. In a gun-cleaner, a swab, and a resilient vermicular core extended lengthwise through the swab, substantially as specified.
2. 1n a gun-cleaner, a swab, a vermicular core on which the swab is mounted, and means for moving the swab lengthwise of the core, whereby the swab may be caused to take the form of the core to increase its diameter, substantially as specified.
3. 1n a gun-cleaner, a swab formed of a plurality oi' disks, a vermicular spring-yielding core in the swab, and means for moving the swab lengthwise of the core, whereby the.
disks may be thrown out of alinement to increase the diameter of the swab, substantially as specified.
4. In a gun-cleaner, a swab consisting of disks formed of metal fabric, a vermicular core extended through the swab, a disk on the end of the swab having an opening, the core being extended through the opening, a spring arranged between said disk and a head on the end of the core, and means at the opposite end of the swab for moving it on the core to force the disks out of alinement, substantially as specified.
5. In a gun-cleaner, a tubular rod, a pushrod movable therein, a sleeve movable on the end of the tubular rod and adapted to be moved b v the pushrod, a perforated disk arranged loosely on the end of the sleeve, a Vermicular core extended through the perforation of the disk, a swab material on said core, a perforated disk engaging with the outer end of the swab and through which the core passes, and a spring arranged between said last-named disk and a head on the end of the core, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE HENRY GARRISON.
