GUN-CIEANER. I

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed May 5, 1907. Serial No. 872.170-

citizen of the United States, residing at Boise,

in the county of Ada and State of Idaho, have invented a new and useful Gun-Cleaner, of whichthe following is a specification.

This invention has reference to improvements in gun cleaners, and its object is to produce a gun cleaner which, after being lnserted in the barrel of a gun, may be given any desired degree of expansion therein and may then be rotated or moved longitudinally in the gun barrel without danger of changing the adjustment already established.

The invention consists essentially in a threaded stem provided with an expansion nut, said stem being rotatable in a suitable base carrying a number of flexible fingers terminating in cleaningpads. The relation of the fingers to the nut is such that when the nut is moved on the threaded stein in one direction the fingers are allowed by their resiliency to approach each other, while when the nut is moved in the other direction on the stem the fingers are ex anded against the action of their resihency. In order to turn the threaded stem to cause the nut to move thereon, the nut being held by the fingers from rotation, the cleaner rod carries at its end a rotatable sleeve fast for rotation to the threaded stem and movable longitudinally thereon, while the supporting.

member for the fingers is provided with bayonet slots or equivalent means whereby the sleeve and stem may be locked to the finger carrier so that the entire cleaner head may be rotated within the gun barrel or moved longitudinally therein without dan-j ger of disturbing the relation of the nut and fingers in any manner.

The invention will be fully understood from the following detailed description,

drawings forming part of this speci longitudinally with reference thereto.

Referring to the drawings, there is shown a threaded stem 1 upon which is mounted a nut 2 of general tetrahedral form such as is commonly used in gun cleaners and in other relations where an expansion nut is desired. The stem 1 passes centrally through a cylindrical block 3, which latter has undercut grooves formed in it for the reception of cleaner blades 4 fast to its periphery by screws 5. The cleaner blades carry at their outer ends suitable pads 6 of wire gauze or some such material, and on their inner faces are provided with guide frames 7 fast to the ends of the blades and so shaped as to coact with the nut 2. These blades have a normal tendency to approach the stem 1 so that when the nut is screwed toward the end of the stem the blades will approach the stem and thus be adapted to easily enter the bore of the gun. But when the nut is screwed toward the other end of the stem it engages the ends of these blades with a constantly increasing diameter and therefore causes them to spread outwardly. This brings the pads to bear with any desired force upon the inside walls of the gun barrel, and by twisting and moving the cleaner head back and forth every part of the gunbarrel may be reached and treated by the cleaner head with any desired degree of force.

The screws 5 which hold the blades 4 are long enough to enter the bore of the block 3 and extend into an annular groove 8 in the stem 1, so that the latter, while freely rotatable Within the block 3, cannot be moved :thegear of the annular'groove 8 the stem 1 is provided with a longitudinal through slot 9 and ultimately terminates in a reduced stem 14.

The block 3 is provided at its rear side with a reduced neck 11 in the rear end of which are formed 2 longitudinal slots 12-having a right angle extension 13 at one end after the manner of an ordinary bayonet catch. Fitted to the neck 1 1 there is a sleeve 14 throu h which passes a pin 15 extending diametricafly through the walls of the sleeve 14 and through the slot 9 in the stem 1. This pin is also adapted to the longitudinal slots 12 in the neck 1 1 and may be moved longitudinally on said neck until the sleeve meets the body of the block 3 when by rotating the sleeve 14 on the neck 11 the pin 15 will enter the angle extensions 13 of the slots 12, thus locking this sleeve firmly in place and at the same 7 time locking the stem 1 against rotation. l When, however, the .sleeve is pulled away from the block 3 to the full length of the slot 9 the pin 15 is beyond the end of the neck 11 although the sleeve still remains on the said neck. When in this position the sleeve'may be freely rotated upon the neck and carry the stem 1 with it. This will cause the nut 2 to travel in one direction or the other on the sleeve since this nut is held from rotation by the engagement-of the free ends of the cleaner blades 4. I v a The sleeve 14 is provided with an axial 15 passage for the reception of the reduced portionlO of the stem 1, and the sleeve 14 is also provided with a threaded neck 16 for the reception of a threaded socket 17 formed on 1 the end of'the cleaner rod 18, which latter, of 20 course, may be of any length desired.

' It will now be seen that the cleaner may be introduced into a gun barrel in the contractedcondition and after being introduced the, nut may be caused to travel toward the block 3 by rotating the sleeve 14 when in a'position to have the pin 15 back of the neck 11. This will cause the expansionof the pads 6 against the inside walls of the un barrel with any force desired, after whic the sleeve 14 may be pushed to carry the pin 15 into the slots 12 and'by a turn of the sleeve the latter may be locked in the extensions 13 of these slots. When so locked,-the cleaner head may be ro- .tated and moved longitudinally in the gun barrel in either direction without danger of changing the diameter of the cleaner head or afle'cting it in anyway, and the cleaner head may be ti htened or loosened by simply reversing the direction of rotation and pull- 40 ing the cleaner rod 18 toward the operator,

when the sleeve 14 with the stem 1 may be rotated in either direction." Iclaim:

gun cleaner comprising an ex-- v:,pansible and contractilercleaner head means for causingthe expansion and contraction of the cleaner head, a rotatable member carried by the cleaner rod, and a lock forcoupling the rotatable member to the cleaner 'head and at the same time looking the means for causing the expansion and contraction of the said cleaner head.

3. A un cleaner comprising a'rotatable,

threade stem, a nut carried thereby, cleaner blades in operative relation to thernut, a block carrying said cleaner blades and holding said'stem against longitudinal movement but, permitting its rotation, a reduced neck formed on said block and provided with bayonet catch grooves, a sleeve fitting said neck and movable longitudinally thereon, and a pin passing throu h said sleeve and through a slot in the t eaded' stem and' adapted to be moved with said sleeve longitudinally with relation to said steminto and out of the slots in the neck of the block.

4. A gun cleaner comprising a threaded stem provided with an annular groove and with a longitudinal slot, a nut carried by'the threaded portion of the stem, cleaner blades provided with cleaner pads and inoperativev relation to said nut, a block carrying said cleaner blades and having means entering the annular groove in the stem to hold the same against longitudinal movement with relation to the block, a reduced neck formed on said block and provided with angle slots, a sleeve adapted to said neck and having a reduced portion to receive a cleaner rod, and a pin passing diametrically through the sleeve and throu h the slot in the stem and movable longitu 'nally with relation to the stem to enter the angle slots formed in the neck ofthe block.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature 95 in the,presence of two Witnesses.
