Dec. 2, 1952 v. G. WALSH GUN REPAIR TOOL Filed May 31, 1949 INVENTOR VEQN 6. WALSH Patented Dec. 2, 1952 UNITED STATES PATENT OFFICE GUN REPAIR TOOL Vern 'Walsh, Fredericksburg, Va.
Application May 31, 1949, Serial No. 93,170
3 Claims.
This'inventionirelates to gun repair tools, and more particularly to a hand tool for removing dents from shotgun barrels and similar tubular structures.
.It is among the objects of the invention to provide an improved gun repair tool for removing dents from shotgun barrels, which tool is effective to accurately remove a dent and restore the gun barrel to its original circular cross sectional shape without stretching the metal of the barrel or producing any bulge in the portion of the barrel operated upon and without a'ifecting any other portion of the barrel, which is readily adapted for use in gun barrels of different bores or gauges, which will easily reach a dent regardless of the location of such dent longitudinally of the gun barrel, and which is simple and durable in construc" tion, economical to manufacture, and extremely easy to use.
Other objects and advantages will become apparent from a consideration of the following descriptionand the appended claims in conjunction with the accompanying drawing, wherein:
Figure l is a longitudinal elevation of a gun barrel repair tool illustrative of the invention shown in position alongside a conventional gun barrel to measure the distance of a dent in the barrel from one-end of the latter;
Figure 2 is a longitudinal, medial cross-section through the gun barrel repair tool, taken substantially on the line 2-2 of Figure 1;
Figure 3 is a longitudinal elevation of a fragmentary end portion of the tool with the tool rotated approximately QO-degrees from the position illustrated in Figure 1;
Figure 4 is a longitudinal, medial cross-section on an enlarged scale of a fragmentary end portion of the tool and is taken substantially on the line 4-4 of Figure 3;
Figure 5 is a transverse cross-section on the line 55 of Figure 2;
Figure 6 is a transverse cross-section on the line 6-6 of Figure 2;
Figure 7 is a transverse cross-section on the line '|--'I of Figure 2;
Figure 8 is an end elevation of the tool disposed in a gun barrel, the barrel being shown in transverse cross-section; and
Figure 9 is a view similar to Figure 8 showing the tool in a different operative position in the gun barrel.
With continued reference to the drawing, the improved gun barrel repair tool comprises, in
general, an elongated, tubular shaft 13, an anvil l2 positioned adjacent to and spaced from one end of the shaft it and mounted on the shaft for projectile and contractile movement transversely of the shaft, and a rod H extending through the shaft Iii and mounted for sliding movement longitudinally thereof. The rod H adjacent one end thereof is provided with a means or cam surface It which engages the anvil ['2 to effect the projectile movement upon sliding movement of the rod ll in one direction. An elongated sleeve or nut I3 is rotatably supported on the other end of the rod H and abuts against the other end of the shaft for 'eifecting the sliding movement of the rod. A graduator plunger is resiliently mounted on the nut It. An aperture'd abutment I5 is slidably mounted upon the shaft In.
The shaft Ill is an elongated metal tube having in one side thereof a longitudinally-extending, flat groove It extending entirely to one end of the shaft, but terminating short of the opposite end of the latter, and having a longitudinally-extending slot I! which is materially shorter than the groove IE5 and is spaced approximately degrees around the tubular shaft from the groove. This slot opens to the same end of the shaft to which the groove 16 extends, and the shaft is provided, near its opposite end, and in line with the groove IS with a stepped,
rectangular opening I8 through which the anvil l2 extends, the larger area of the opening I8 being at the outside of the shaft.
The rod l I is recessed near one end to provide, at the end of the shaft I0 carrying the anvil I2, the inclined cam surface 19 underlying the anvil, and is provided, at its opposite end, with an externally screw-threaded portion 20. A pin 2| projects laterally from the rod II near the inner end of the screw-threaded portion 2a of the latter, and is slidably received in the slot l"! in the shaft l0 to maintain the rod against rotation relative to the shaft.
The nut l3 comprises an internally screwthreaded, cylindrical portion 22 which is threaded onto the screw-threaded portion 23 of the rod II and bears against the adjacent end of the shaft [0, a hardened thrust washer 23 preferably being disposed in a recess in the end of the nut surrounding the screw-threaded aperture therein. An elongated boss 24 extends outwardly from the cylindrical portion 22 of the nut and is provided, at its end remote from the cylindrical portion 22, with a restriction 25 which receives the plunger with a close sliding fit. Nut-turning handles 26 project laterally outward from the cylindrical portion 22 of the nut in positions substantially diametrically opposed to each other, so that the nut can be easily turned on the screw-threaded Portion of the rod. Near its end engaged by the nut I3, the shaft I9 is provided with an annular groove 21, and a latch plate 28 is secured to the nut by suitable means, such as the screw 29, and has a detent 30 received in the groove 21 to hold the nut I3 against movement toward and away from the adjacent end of the shaft I9.
Since the rod II is slidable Within but is held against rotation relative to the tubular shaft Ill, and since the nut I3 is threadedly engaged with the rod but is held against movement toward and away from the shaft, rotation of the nut will be effective to shift the rod slidably within the shaft.
The anvil I2 is a two-part structure including a slide 3| bearing upon the inclined cam surface I9 of the rod II, and a rectangular block 32 fitting in the enlarged outer portion of the opening I8 in the shaft ID, and provided with a bifurcated tongue 33 extending through the restricted portion of the opening 18. The runner 3| carries, substantially at its mid-length location, an outwardly-extending apertured lug 34 which is received between the two sides of the bifurcated portion 33 of the anvil block, and a pivot pin 35, extending transversely of the shaft I9, pivotally secures the block portion to the runner portion of the anvil.
The outer surface of the anvil block is rounded substantially in conformity with the cylindrical curvature of the shaft I0, and the pin 35 provides a sufficient freedom of rocking motion for this block portion of the anvil, so that outward pressure exerted on the anvil by the cam surface I 9 of the rod II will be directed entirely against a dent in the gun barrel and not against the portion of the barrel at one end or the other of the anvil block. The inclined surface I9 is inclined outwardly toward the adjacent end of the rod, so that when the nut I3 is threaded inwardly on the rod II, the anvil will be forced outwardly of the shaft I9.
The plunger I4 is an elongated pin having a head 36 on its end disposed within the nut I3, this head being rounded to provide a rounded bearing surface for the adjacent end of the rod II. A spring 31 is disposed between an internal shoulder provided by the restriction 25 at the outer end of the boss 24 of nut I3, and the head 36 of plunger I4, to resiliently urge the plunger inwardly of the nut, and the plunger is provided with longitudinally-extending gradations 38 which are visible at the outer end of the nut I 3 to indicate the position of the rod II and. the anvil I2 relative to the shaft Iil. The nut I3 is preferably conically tapered at its outer end, as indicated at 39, to facilitate the reading of the graduations on the plunger I4.
The abutment I comprises an apertured ring portion 40 which slidably receives the shaft Ill and is provided with a screw-threaded aperture 4| extending through the wall thereof. A set screw 42 in the form of a thulnbscrew or wing screw is threaded through the aperture M in the abutment 40 and engages in the groove I6 to lock the abutment in adjusted position longi tudinally of the shaft I0, and also secures the abutment to the shaft against rotation relative to the latter. This set screw 42 is provided, at its outer end, with a sighting point 43 for a .4 purpose which will presently appear. A handle 44 extends laterally outward from the ring portion 49 of the abutment for rotating the tool, under certain conditions, and for holding the tool against rotation while the nut 13 is being threaded down on the screw-threaded portion of the shaft I I.
In using the tool, after the gun barrel has been removed from the stock and forearm of the gun, the tool is laid alongside the barrel with the anvil opposite the dent to be removed, as illustrated in Figure 1. The shaft ID of the tool will extend beyond one end or the other of the gun barrel, depending upon the location of the dent longitudinally of the barrel. In the arrangement illustrated in Figure 1 the shaft extends beyond the muzzle end of the barrel. With the shaft I0 held against the barrel so that the anvil I2 is opposite the dent, and with the set screw 42 loosened, the abutment I5 is moved along the shaft I0 until it bears against the adjacent end of the gun barrel, whereupon the set screw 42 is tightened to lock the abutment in adjusted position longitudinally of the barrel; With the nut I3 loosened, and the anvil I2 fully retracted, the anvil end of the tool is then inserted into the barrel until the abutment bears against the end of the barrel and the tool is rotated until the anvil is disposed at a location substantiallyv degrees from the location of the dent in the barrel, this position of the tool being particularly illustrated in Figure 8. With the anvil at the location of Figure 8 the sighting point 43 indicates that the anvil is in the 90 degree position with respect to the dent. The nut I3 is then tightened until the anvil is brought firmly into contact with the inner surface of the barrel, but not sufficiently to, in any way, change the shape of the barrel. With the nut thus tightened, the graduation of the plunger I 4, at
the outer end of the nut I3, is carefully noted and the screw is then loosened to again retract the anvil. The tool is then rotated by the handle 44 from the position illustrated in Figure 8, to the position illustrated in Figure 9 in which the anvil I2 is directly opposed to the dent in the gun barrel. The nut I3 is then tightened again until the same graduation on the plunger I4 comes to the outer end of the nut I3. been exactly forced out of the gun barrel, and the barrel restored to its original, circulancrosssectional shape without any overstretching of" the metal or any bulging of the barrel at-or near the location of the dent. The nut I'3 may: now again be loosened to retract the anvil and the tool removed from the gun barrel. During the operations of tightening and loosening the nut I 3, the latch plate 28 holds the nut to the end of the shaft I9 and causes the rotation of the nut to impart longitudinal movement to the moving dents from shotgun barrels, it may 'ob-' viously be used to straighten other tubular structures, if desired.
The invention may be embodied in other specific forms without departing from the spiritor essential characteristics thereof. The present' embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the
scope of the invention being indicated by thei When this occurs, the dent will have appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
