EJECTOR NIECHANISIVI FOR BREECH-LOADING FIREARNIS.

SPECIFICATION forming part of Letters Patent No. 673,641, dated May 7, 1901. Application filed December 31, 1900. Serial No. 41,653. (No model.)

To @ZZ wir/0712, t may concern:

Be it known that we, CHARLES A. KING and JAMES P. HAYES, citizens of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Ejector Mechanism for Breech-Loading Firearms, of which the following is a specification.

This invention relates to those ejector mechanisms for breech-loading firearms which are so constructed that they do not eject a cartridge-shell when the breeches are opened unless it has been fired.

The object of the invention is to devise an ejector mechanism of this nature having parts so constructed and arranged that they will be simple and cheap to make and assemble and also sure and easy in action and durable in service.

In the accompanying drawings the invention is illustrated in connection with a double-barrel hammerless breakdown shotgun of the type known as the Parker gun, and the ejector mechanism that is shown has a rod fastened to each ring-hammer mainspringplu nger and projecting beyond the hinge-joint at the front end of the frame into the path of the rear end of a rearwardly-spring-pressed slide. Each slide has an inwardly-projecting stud that extends in front of an arm of a 1ever that is provided with a retaining-shoulder and a Sear-shoulder. Each of the levers has its rear end lifted upwardly by the pressure of a spring for causing its retaining-shoulder to move into position to engage with a retaining-shoulder on an ejector-hammer when the barrels are tipped to open the breeches and the ring-hammer is cocked, and each of the levers has its rear end forced downwardly by the push of a slide-stud for causing the engagement of its Sear-shoulder with a searshoulder on an ejector-hammerwhen the firing-hammer is snapped forward. Each of the ejector-hammers when its Sear-shoulder is free from the scar-shoulder of its lever and its retaining-shoulder is not obstructed by the retaining-shoulder of its lever is thrown rearwardly by the tension of an arm of a leafspring and caused to forcibly engage the front end of an ejector-stem. Each ejector-stem when the barrels are tipped and the breeches are opened is by the engagement of a shoulder with a projection from a part of the frame given a slight rearward movement for starting the shells from the breeches of the barrels, each lever being moved for disengaging its Sear-shoulder from the Sear-shoulder of its ejector-hammer by the engagement of its rear end with a portion of the frame when the barrels have been tipped for opening the breeches sufficiently to allow a shell to be ejected rearwardly past the top of the frame. The ejector-hammers when the barrels are tipped for closing the breeches are forced forwardly, so as to be in position to be engaged by the retaining-shoulders when the barrels are again tipped for opening the breeches by a toggleblock that extends between the back edges of the ejector-hammers and the front edge of a part of the frame.

Figure 1 of the views shows aplan ofa portion of a double-barrel breech-loading hammerless shotgun provided with the improved ejector mechanism. Fig. 2 is a side elevation with portions broken awayof the ejector mechanism for one barrel, showing the mechanism in the position occupied when the firing-hammer is cocked and a loaded shell is in the barrel. Fig. 3 is a similar View showing 'the same parts when the firing-ham mer is forward and the shell has been fired. Fig. 4 is a side elevation showing the parts in the positions occupied with the firing-hammer cocked and the barrel tipped so as to open the breech and allow the mechanism to eject a fired shell. Fig. 5 is a plan of the fore-end iron of the gun. Fig. 6 is aside elevation of the fore-end iron with the slides which it carries in their-forward positions. Fig. 7 is a similar view of these parts with the slides pressed rearwardly. Fig. 8 shows side and edge views of an ejector hammer. Fig. 9 shows similar views of a lever with its retaining and sear shoulders. Fig. l0 shows views of the toggle-block for cooking the ejectorhammers, and Fig. ll shows views of the hinge-joint block.

The frame l is fastened to the stock 2, the barrels 3 are hinged to the frame by the pivot 4, and the fore-end iron 5 is attached to the barrels in the ordinary manner. The firinghammers 6 are concealed in the frame and by IOO sears '7 are heldcocked against the push of I side the plungers 8, that are forced rearwardly by spiral springs 9, located in chambers in the front part of the frame, the plungers and the firing-hammers being connected by means of the links 10, that are pivoted to the hammers and enter recesses in the back ends of the plungers, as set forth in the patent to Charles A. King of March 1, 1892.

Each rod 11, that is fastened to and projects forwardly from the mainspring-plu nger, is of such length that when its iiring-hammer is cocked and the plunger is forced forward its front end extends beyond the front end of the frame; but when its firing-hammer is thrown forwardly and the plunger is forced back its front end is withdrawn into the front end of the frame.

The front end of each plunger-rod when forward engages the end of a slide 12, movable in the side of the fore-end iron. Each slide is norfnally forced backwardly by a spiral spring 13, and projecting from each slide into the ej ector-hammer recess 14 in the fore.- end iron is a stud 15.

The ejector-hammers 16 are pivotally held in the center of the recess in the fore-end iron by a pin 17. The back edges of these hammers engage with the front ends of the ejector-stems 34:, and they are held in such engagement and are normally thrust rearwardly by the upper arms of leaf-sprin gs`19.

Two levers 20 are pivoted in the recess in the fore-end iron between the ejector-hammers. One end 21 of each lever extends upwardly toward the top of the fore-end iron just in the rear of a slide-stud 15, and the other end 22, which is normally forced upwardly by a spring 23, extends rearwardly to the front end of the. frame. These levers have retaining-shoulders 24, that when the ejector-hammers are pushed forward and the levers are lifted by their springs occupy positions just in the rear of and out of contact with retaining-shoulders 25, formed on the inside faces of the ejector-hammers, so that the lever-retaining shoulders will engage with the injector-hammer-retaining shoulders and retain the ejector-hammers when the barrels i are tipped for opening the breeches if the firing-hammers are cocked. On the opposite edges of these levers are the Sear-shoulders 26, that are arranged to engage with scarshoulders 27 on the inside faces of the ejector-hammers when the firing-hammers are thrown forwardly and the slides are permit-` ted by the plunger-rods to be forced rear-v wardly and through the engagement of the slide-studs with the upper ends of the levers` cause the levers to be oscillated, so that their` rear ends move downwardly against the push of their spring.

A joint-block 28 is located about the pivot that connects the frame and the fore-end iron. This block, which is secured in position so` -V that it will not rotate, has a shoulder 29, ar-

ranged to engage shoulders 30 on the under of the ejector-stems 34 when the barrels tipped, so as to positively commence the ejection of the fired shells. This block also has on the front edge a shoulder 31, which shoulder is arranged to be engaged by the rear ends of the levers when the firing-ham mers are forward and the barrels are tipped, sov that further tipping of the barrels will cause the Sear-shoulders on the levers to be disengaged from the Sear-shoulders on the ejector-hammers and allow the ejector-hammers to be thrown rearwardly and complete the ejection of the fired shells.

Between the fixed front edge of the jointblock and the back edges of the ejector-hammers a block 32 is placed. The front end of this block has lugs 33, that project outwardly little wider than the width of the opening to the rear from the recess in the fore-end iron, so that the link, although loose, cannot drop from position. When the barrels are tipped for closing the breeches, this block, actingas a toggle, forces forwardly the ejector-hammers, so that the levers may be lifted by their springs and their retaining-shoulders placed in the path of the retaining-shoulders of the ejector-hammers.

The ejector-hammers are prevented from snapping back by the retaining-shoulders as long as the firing-hammers are cocked, and when the parts are in such relation the barrels may be tipped for opening and closing the hreeches indenitely without Vreleasing IOO the ejector-hammers and allowing them to jecting studs by engagement with the upright parts of the levers cause the levers to be oscillated against the push of their springs and the retaining-shoulders to be moved out of the path of the ejector-hammers and the searshoulders to become engaged. Then the next time the barrels are tipped for opening the breeches the ends of the levers l,will engage with the projections from the joint-block in such manner as to cause the disengagement of the Sear-shoulders and allow the snapping of the ejector-hammers.

The levers, with their retaining-shoulders, Sear-shoulders, and tripping ends, the levermoving slides, the ejector-hammers, and the cooking toggle-block, are very simple to make and assemble. The action of these parts is easy and powerful and the movements so caused that there is little wear, and vwhat wear does occur will not affect the sure, accurate, and safe operation of the mechanisms.

Cooking the ejector-hammers by means of l ducing the wear, insures a smooth and easy action when the parts are operated.
