Abstract
ABSTRACT
An apparatus for loading shotguns or rifles to capacity in one operation by the use of a pre-loaded portable tubular magazine (2) which can be locked inside a rigid steel guide tube (6) connected to the firearm in place of it's conventional tubular magazine.
The portable tubular magazine (2) comprises a rigid steel tube capped at one end and tapered at the other to contain a magazine spring (15) and cartridge pusher (16). Cartridges (17) are inserted over a spring loaded cartridge retainer (18) and are released inside the guide tube (6) when the cartridge retainer lifter (9) is raised by ramps (10) at the end of a slot (12) which forms a channel in the guide tube (6) for the cartridge retainer housing (21). The fore end (7) fitting over the guide tube (6) is similarly slotted and is connected to conventional slide bars (8).
At the front end of the guide tube (6) limiting the forward travel of the fore end (7) a two piece barrel clamp (3) incorporates mounting brackets (4) for lock levers (5) having two laterally spaced teeth.
When the lock ring (14) on the portable tubular magazine (2) engages the front tooth the cartridge retainer lifter (9) is clear of the lifting ramps (10) and cartridges are not released until the ring (14) engages the back tooth in the fully seated position . In this position it is possible to load cartridges in the conventional manner.

''`` 2 ~ 8 9 101 -, PORTABLE TUBULAR MAGAZINE FOR
SHOTGUN OR RIFLE
TECHNICAL FIELD
This invention relates to shotguns or rifles which are fitted with a tubular magazine as a means of holding cartridges in end to end alignment beneath the barrel in r@adin~ss Eor being cycled into the Eiring chamber or for being removed if they are unused.
BACKGROUND ART
Traditionally cartridges have been loaded into the tubular magazine of a shotgun or rifle singly through a loading aperture on the side or on the bottom of the receiver. They can then be transferred to the firing chamber and ejected after being fired. Unfired cartridges can be removed from the tubular magazine by being cycled through the firing chamber or, in some cases, by being released through the loading aperture in which case the firing chamber is by-passed. In both cases unfired cartridges are ejected onto the ground unless they are caught by hand as they are being ejected. Spare cartridges are carried loose in boxes or pouches or they are carried sometimes in belt loops.
.
DISCLOSURE
This invention eliminates the need to handle loose cartridges while the tubular magazine of a shotgun or rifle is being loaded or unloaded and it provides a means of loading or unloading a full charge of cartridges in one simple operation. This is made possible by the utilization of a portable tubular magazine in "conjunction with a guide tube, fore end and locking assembly. The locking assembly allows the portable ~`30 tubular magazine to be locked inside the guide tube in two positions to provide a degree of safety not found in firearms fitted with conventional fixed tubular magazines. When locked in the first position no cartridges can be released from the portable tubular :`
r~" 102 2~0 889 magazine even when the action is cycled.
Cartridges can be loaded into or removed from a portable tubular magazine when it is separated from the firearm or when it is locked inside the guide tube which is connected to the firearm's receiver in place of it's conventional, Eixed, tubular magazine. When the portable tubular magazine is locked inside the guide tube cartridges can be loaded or unloaded in the conventional manner or, alternatively, a portable tubular magazine, with or without car~ridges, can be inserted into or can be removed from the guide tube at any time.
A portable tubular magazine consists of a rigid steel tube haviny a threaded end cap at one end and a tapered or crimped opening at the other which serves to contain within the portable tubular magazine a cartridge pusher and a magazine spring.
On the bottom center line inside the portable tubular magazine near the open end a short steel retaining pin blocks the exit of any cartridges which have been inserted. The rear face of this cartridge retainer is beveled so that it can be deflected by cartridges as they are being inserted. To ensure that this bevel always faces the rear a square stem on the other end of the cartridge retainer is made to fit through a square hole in the end of the housing which contains it. Also contained within this housing is a compression spring which keeps the cartridge retainer in the extended - position. To release cartridges from the portable tubular magazine the cartridge retainer is retracted by raising a button-shaped lifter connected to the cartridge retainer stem outside of the housing.
Cartridges are held inside the portable tubular magazine ~between the cartridge retainer and the cartridge pusher ;~which, being slightly larger in diameter than a ~35 cartridge, cannot be pushed by the magazine spring ~ ~5~9 through the tapered or crimped open end. The cup-shaped cartridge pusher fits over the back end of the magazine spring and to ensure that cartridges can be pushed Completely out of the portable tubular magazine the rear face of the cartridge pusher can be stepped down to a smaller diameter and made longer to suit the taper or crimp at the open end.
A small steel lock ring encircles the portable tubular magazine towards it's front end and when the portable tubular magazine is fully seated within the guide tube the ring is held against the mouth of the guide tube by the second of two beveled teeth on spring-loaded lock levers.
Flat sides are machined onto the end cap on two sides and the bottom while the top side is left rounded. The shape of the end cap is an aid in determining when the vertical axis of the portable tubular magazine is in proper perpendicular alignment for inserting the portable tubular magazine into the guide tube.
The front end of the rigid steel guide tube is flared slightly to ease the entry of the portable tubular magazine and the other end is fitted with a connector which matches the connector socket of the receiver to which it is to be attached. The length of the guide tube is such that the free operation of the sliding fore end it supports is not hindered and ample space is provided `to mount the barrel clamp and the lock levers. The underside of the guide tube is slotted to provide a channel for the cartridge retainer housing and -~30 lifter. This slot~e~xtends backwards from the front end of the guide tube to a point just in front of the receiver `connector. Steel wedges tapered toward the front are fitted one on each side of the slot at the back end to form a ramp up which the lifter rides to retract the cartridge retainer when the portable tubular magazine is ~`
~``~ 2~88~ :
fully seated within the guide tube. Slots or notches on the t~o sides of the guide tube flare form openings through which the lock levers engage the lock ring on the portable tubular magazine. The two lock levers are mounted in brackets which are incorporated in the barrel clamp located just behind the flare of the guide tube.
The portable tubular magazine can be pushed into the ~uide ~ube llntil the lock ring is held behind one of two lock lever teeth, however, when the lock ring is locked behind the front tooth the cartridge retainer lifter has not yet made contact with the lifting ramps so no cartridges are released from the portable tubular magazine.
Lock levers are held in the locking position by compression springs located in the lock lever mounting brackets. Pressure on the back end of the lock levers cause the teeth to be lifted clear of the lock ring and the portable tubular magazine can be withdrawn from the guide tube.
In order to avoid obstructing the line of sight or the guide tube slot a two-piece barrel clamp can be used to secure the barrel to the guide tube.
Fitted over and supported by the guide tube, the fore end is made of steel tubing having wooden side grips and, - 25 like the guide tube, the fore end is slotted on it's underside to provide a channel for the cartridge retainer ` housing and lifter.
Standard unaltered~slide bars connect the fore end to the mechanism inside of the receiver and they prevent any ~ 30 turning of the fore end which would occlude the slot "~ opening on the guide tube.
The sliding fore end is replaced by a fixed, slotted forearm in shotguns or rifles employing lever action or auto-loading mechanisms.

The forward travel of the fore end is limited by the barrel clamp, therefore, the wooden side grips cover only that part of the fore end tubing that does not have to pass under the back end of the lock levers.
When the portable tubular magazine is used to store cartrldges it can be made wa-tertight by closing the open ~nd with a rubber cap and by the use of rubber ~askets in ~he end cap and on the end of the stem of the cartridge retainer under the lifter.
DESCRIPTION OF DRAWINGS
FIG. 1 is a side view, partly in section, of the guidé
tube containing a portable tubular magazine and clamped to the barrel of a firearm.
FIG. 2 represents line 111-111 of FIG. 1.
Drawings are not to scale in order to show more clearly details of the various components and the receiver and the stock of the firearm are not shown.
BEST MODE FOR CARRYING OUT THE INVENTION
The main body component of the portable tubular magazine, guide tube and fore end are sawed from lengths of round steel tubing and matching slots are then milled in the underside of the guide tube and fore end pieces while a male thread is cut on one end of the section forming the portable tubular magazine.
`.25 A press and forming dies are used to produce the rear taper on the portable tubular magazine as well as the ~`barrel clamp halves and the flare at the front end of the guide tube.
Lock lever slots in the guide tube flare and the square hole in the end of`the cartridge retainer housing are punched in a press.
":
~` 2 ~ 9 The cartridge retainer, cartridge retainer lifter, cartridge retainer housing and the end cap are cut and shaped in a la-the from lengths of cold rolled round steel. Blind holes are drilled in the end cap and the cartridge retainer housing sections and a round hole is drilled through the center of the piece to be used for ~he button-shaped cartridge retainer liPter. In the la~he used to drill these holes the edge of the l.ifter is beveled and a female thread is cut in the end cap before ~he pieces are parted off from the length of round stock.
Before a cartridge retainer section is parted off from the length of round stock the end is turned down to form a stem over which the cartridge retainer lifter will be staked. The square section of the cartridge retainer stem and the beveled face of the cartridge retainer is then formed by milling.
Three straight sides must be milled onto the end cap and after the square hole is punched in the cartridge retainer housing it is welded over a hole drilled for the cartridge retainer in the underside of the portable tubular magazine on the taper at the back end.
From a spring-like coil wound from cold drawn square steel stock, lock ring segments are cut and welded on to the forward part of the portable tubular magazine.
Cartridge retainer lifting ramps are sheared from cold drawn square steel stock and are fastened to the underside of the guide tube by welding.
`~With the compression spring over the square stem the cartridge retainer is inserted into it's housing and the `30 lifter is staked to the end of the stem over a rubber gasket outside of the housing.
~ ~ .
~- 2050~89 After lock levers have been formed by stamping, a shallow blind hole is drilled in the underside to the rear of the hole drilled for mounting the lock levers. Another shallow blind hole is drilled in the barrel clamp opposite to the one in the lock lever. Together these holes form the pocket in which the compression spring is held when the lock lever is riveted between the mounting bracket~.
The barrel clamp is bolted together through a hole drilled in the clamp between the barrel and the guide tube and the lower ends of the barrel clamp are riveted to the guide tube to help preserve it's roundness.
INDUSTRIAL APPLICABILITY
Portable tubular magazines, especially in shotguns, are well suited for police or military use during situations where there exists some urgency in reloading. It is also possible to achieve an added degree of saEety when carrying a loaded shotgun in a police or military vehicle because the portable tubular magazine can be locked in the guide tube without releasing any of it's cartridges.
Easily made watertight a portable tubular magazine can be used to fully load a firearm with dry cartridges during periods of inclement weather.
