EXPLOSIVELY-ACTUATED STUD-DRIVING TOOL Filed Nov. 26, 1965 INVENT ROBERT C. K VLE ATTORNEY United States Patent 3,204,400 EXPLOSIVELY-ACTUATED STUD-DRIVING TOOL Robert C. Kvavle, Hillsboro, 0reg., assignor, by mesne assignments, to United Shoe Machinery Corporation, Boston, Mass, a corporation of New Jersey Filed Nov. 26, 1963, Ser. No. 325,951 4 Claims. (Cl. 60-26.1)
This invention, like the invention described in my pending application for patent under the same title, filed February 1, 1963, Serial No. 255,589, now US. Patent No. 3,168,744, relates to explosively-actuated hand tools for driving studs, pins, or similar fastening elements into hard surfaces, and the present application is a continuation-inpart of application Serial No. 255,589, to which reference should be made.
The particular object of this present invention is to provide an explosively-actuated tool, such as that described in pending application Serial No. 255,589, with additional means for adjusting the force of the explosive charge or impact delivered against the piston in the gun barrel and transmitted to the ram attached to the piston, which ram in turn drives the stud, or other fastening element, as the result of the explosive charge delivered against the piston.
The actual amount of the force of impact necessary for the desired driving of a particular stud into place depends on the nature of the surface into which the stud must be forcibly driven. Thus when such surface is softer than that on which the explosively-actuated tool is normally intended to be used, or in other words, when the explosive force produced by the firing of the cartridge in the tool is calculated to drive the stud or fastening element into a harder surface, then the use of the tool on a softer surface results in undesirable overdriving of the tool.
While the explosively-actuated tool described in pending application Serial No. 255,589 is provided with special novel means for presenting any serious damage to the tool in the event of overdriving, the present invention has a related specific object, namely to reduce the possibility of such overdriving of the tool when employed on softer surfaces.
This particular object I am able to achieve by causing some of the explosive force of the fired cartridge to be dissipated and disseminated in its impact against the piston in the gun barrel when the tool is used on softer surfaces than those on which the tool would normally be used.
The manner in which and the means by which this is accomplished, and the way in which the partial dissemination of the explosive force is adjustably controlled, will be described and explained briefly with reference to the accompanying drawings.
In the drawings:
FIG. 1 is a fragmentary sectional elevation of the tool, taken longitudinally along the approximate center or axis of the gun barrel, showing the breech end portion of the gun barrel and adjacent portion of the tool, with the tool in position ready to be fired;
FIG. 2 is a fragmentary top plan view of the same portion of the tool taken on line 22 of FIG. 1;
FIG. 3 is a section on line 3-3 of FIG. 1; and
FIG. 4 is a section on line 4-4 of FIG. 1.
The muzzle portion of the gun and the handle portion, together with the entire firing pin assembly, are omitted from FIG. 1 since these are the same as those of the tool of the pending application Serial No. 255,589 and do not in themselves form part of the present invention.
Referring to FIGS. 1 and 2 of the attached drawings, the tool includes the usual barrel housing on the rear end of which is secured the usual handle assembly 11. Only the forward portion of the handle assembly is shown in the drawing. In the part of the barrel housing 10 "Ice shown in FIG. 1 where is the customary open portion in the top and side to permit access to the gun barrel, the barrel being longitudinally slidable in the housing 10 to a limited extent as usual.
The gun barrel, however, instead of consisting of a single integral member as heretofore customary, comprises a front member 12 (corresponding to the same portion of the barrel of the tool in application Serial No. 255,589), and a specially formed rear member 13, shaped as shown in FIG. 1. The front member 12 of the composite barrel has an annular threaded recess 12' to accommodate the corresponding externally threaded front end 13 of the rear member 13 of the barrel, enabling the rear member 13 to be rigidly secured to the front member and to form therewith a composite gun barrel with a continuous barrel bore.
A piston P is mounted in the composite gun barrel as usual and carries a friction ring 14 on its outer surface which engages the wall of the bore of the barrel so as to prevent inadvertent sliding of the piston in the barrel. A ram having a head 15 and a shaft 16, is removably attached to the piston P. The ram and piston are the same as those of the tool in application 255,589 and therefore need not be described here.
The rear member 13 of the composite gun barrel is provided with an aperture or chamber to accommodate the cartridge C in the usual manner, as shown in FIG. 1. The wall of this rear member 13 has an annular row of equally spaced apertures or ports 17 (FIGS. 1 and 3) positioned in the location shown in FIG. 1. Starting a slight distance ahead of this row of apertures the outer wall of the member 13, as indicated at 18, tapers toward the rear, terminating in a shoulder formed by a reduced diameter end 19, which end is externally threaded.
A control sleeve 20 is rotatably mounted on the member 13 within the housing 10 and is capable of slight longitudinal or axial adjustment with respect to member 13. The interior Wall of this sleeve 20 conforms substantially to the exterior wall of member 13 which it encompasses, having a decreasing diameter portion forming a tapering interior Wall corresponding to the tape of the exterior wall on the rear portion of the member 13. The sleeve 20 also terminates in an internally threaded portion of reduced diameter which mates with the externally threaded end 19 of the member 13.
Thus, as apparent from FIG. 1, rotation of the sleeve 20 on the member 13 will result in longitudinal or axial movement of the sleeve 20 with respect to the member 13. Furthermore relative axial movement of the sleeve 20 with respect to member 13 in a forward direction (thus towards the left as viewed in FIG. 1), produced by rotating the sleeve 20 in one direction, will result in reducing the spacing between the opposed tapered wall portions of the sleeve 20 and member 13 until these opposed portions are brought completely together resulting in the complete closing of the outer ends of the ports or apertures 17 of member 13, while opposite rotation of the sleeve 20 on the member 13, causing opposite relative axial movement of the sleeve 20 with respect to member 13, will cause the outer ends of the ports 17 to be opened to an extent depending on the amount of such relative movement.
When the outer ends of the ports 17 are partially open and the firing -of the cartridge in the tool takes place, a portion of the gas of the explosion, as the piston P is thrust forwardly (thus to the left as viewed in FIG. 1) will then be able to escape through the ports 17 and thence on through the narrow space between the member 13 and sleeve 20, instead of being confined entirely to the bore of the gun barrel behind the advancing piston as customary. This dissemination or loss of some of the explosion gas behind the advancing piston results in reducing the force with which the ram, connected with the piston, is driven, and consequently reduces the force impinged upon the stud by the ram, or, in other words, reduces the force with which the stud is driven. As obvious, the greater the amount of this loss of explosion gas from the barrel behind the piston, the less will be the diving force imparted by the tool. In this way the present invention accomplishes its special object of providing against too much overdriving of the tool when the tool is used on softer surfaces.
In order to prevent inadvertent rotation of the sleeve 2% on the member 13, a plurality of short, equally spaced, parallel, longitudinally-extending grooves 21 are provided on the outer wall of the member 13 beneath the forward end of the sleeve and extending a slight distance beyond the forward end of the member 13. A spring 22 is mounted in an annular groove on the inside wall of the sleeve 20 near the forward end and this spring has an inwardly extending portion 22' adapted to engage the grooves 21 with suflicient spring force to hold the sleeve against inadvertent rotation while also enabling the sleeve to be rotated manually without difiiculty when desired.
As a guide in the setting of the sleeve 20, and consequently for making adjustments of the tool for use on surfaces of different hardness, cooperating indicia are placed on the outer surface of the rear end of the gun barrel portion 12, such as the central indicator mark 23 shown in FIG. 2, and suitable registration markings and notations on the sleeve 20, such as shown for example at 24 in FIG. 2, prefrably the latter being arranged in a shallow annular recess 25. Also preferably the outer surface of the sleeve 20 is formed with a second annular recess 26, resulting in rib portions 27 and 28 which preferably are knurled on their outer surface to facilitate a finger grip on the sleeve when rotation of the sleeve 20 for adjusting the driving force of the tool is required.
Obviously minor modifications could be made in the adjustable sleeve 20 and on the portion 13 of the gun barrel without departing from the principle of the invention, and it is not intended to restrict the invention to the particular form and arrangement illustrated and described or to limit the invention otherwise than as set forth in the claims.
