BREECH-LOADING BREAKDOWN GUN.

SPECIFICATION forming part of Letters Patent No. 522,464, dated July 3, 1894. Application filed May '2, 1893. Serial No. 7 N mo l To all whom it may concern:

Be it known that I, ANSLEY H. FOX, a citizen of the United States, residing in the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Breech-Loading Firearms, of which the following is a specification.

This invention relates to certain improvements in that class of breech loading fire arms, known as hammerlessbreech-loading break-down guns, and it has for its objects to provide a gun in which the locking and firing mechanism is inclosed in the forward part of the gun-stock or breech-block; and also to provide certain improvements in the locking and firing mechanism wherebyits construction is simplified and precision in operation is secured.

The invention consists in providing the gun with a sliding locking-bolt which engages a ing at the breech of the barrel behind the pivot or hinge, by which the barrel is secured to the stock and mechanism for operating the same, the bolt and said mechanism being entirely inclosed with the fore part of the stock, with the exception of the knob, by which the mechanism is manipulated, as more fully hereinafter set forth.

The invention further consists in the cornbination with the hammer of the gun and the barrel thereof, of mechanism whereby the hammer is thrown back or cooked, automatically, on turning or breaking down the barrel; and further, to improved safety mechanism in combination with hammer and trigger, whereby the trigger and hammer may be locked when desired as more fully hereinafter set forth.

The invention also consists in so arranging the hammer in relation to the cooking ing as to permit the cooking arm of said hammer to freely pass the lug upon firing, and in improved mechanism whereby the hammer is caused to rebound after impact, and the invention stillfurther consists in certain details of construction more fully hereinafter set forth and specifically pointed out in the claims. v

The above mentioned objects are attained by the means illustrated in the accompanying drawings, in which like reference numerals indicate similar parts in the respective fign res.,

In the drawings, Figure 1 represents a longitudinal sectional view of the breech portion of the gun, and the fore-part of the stock, showing the safety and firing mechanism. Fig. 2" represents a similar view showing the barrel broken down and the hammer set or cooked, and. the safety mechanism set at safety. Fig. 3, represents a longitudinal,sectional view of the gun showingthe barrel and the firing mechanism in position ready for the firing operation. Fig. 4, is a view of the opposite side of the gun showing the barrel in normal position and illustrating, by dotted lines, the locking mechanism in engagement with the lugs at the breech of the barrel, locking the same, and the safety mechanism in connection therewith. Fig. 5, is a view similar to Fig. 4, showing a modification of the mechanism for locking the barrel to the breech-block or stock of the gun. Fig. 6 is a detached view illustrating the locking bolt and safety block, the said safety block being in its forward position and provided with an adjustable screw, by the adjustmentof which the safety block is made automatic or non-automatic. Figs. 7 and 8 are detail views, illustrating means for attaching and detaching the cooking lug. Fig. 9 is a detail view illustrating in plan the construction of the sear spring, and Fig. 10 is a side elevation,partly in section, illustrating the combination and co-operation of my mechanism.

Referring to the drawings, the numeral 1 indicates the fore part of the stock of a gun, within which the locking and firing mechanism is located.

The numeral 2 indicates the barrel of the gun which is pivoted or hinged to the fore end of the stock,- as indicated by the numeral 3, in the ordinary manner. The breech block is of the usual construction and is indicated by the numeral 4..

The numeral 5 indicates the hammer or firing lever which-is fulcrumed at 6 in the fore part of the stock. The said hammer is provided with a forward extension 7 which is cast integral therewith or fastened securely there to in any convenient manner.

tension is provided with lateral flanges atits upper and lower edges,as shown particularly in Figs. 1, 2, and 3 ofthe drawings, or pins or lugs, not shown in the drawings, maybe The said eX-I secured in any desired manner to said forward extension, with which flanges or lugs the free ends of the main spring 11 engage. The said spring at its forward end is provided with a lug or pin 12, or other suitable fastening, to rigidly secure the same to the metallic portion of the fore part of the stock.

The numeral 13 indicates a lug depending from the breech of the barrel and provided with a lug 14: at its lower end, made integral with lug 13 or detachable therefrom to compensate for wear, or said lug lat may consist of a friction roller suitably attached to said depending lug, which engages and rides below the fore end of the hammer extension 7, so as to elevate said extension and throw the hammer back to cocking position, as shown in Figs. 2 and 3 of the drawings, during the operation of breaking down the barrel for the purpose of reloading the gun. The hammer at its rear is provided with a notch or shoulder 15, with which the fore end of the sear 16 engages when said hammer is in a cocked position, as shown in Figs. 2 and 3 of the drawings. The said sear is constructed in the usual way, preferably in one piece, constitutin g a long and short armed lever which lever or sear is fulcrumed at 17 in the metallic frame of the fore part of the stock. The long or rear arm of said sear rests upon the fore end of the trigger 18, which is also fulcrumed at 17, or it may be in a slot in the lower part of the said frame above the guard 20. The rear of the trigger has an obliquelyrising extension 21, over which the safety block 22 may be set to lock the trigger and hammer when required. The said safety-block is rectangular in shape and on its bottom is provided with two curved recesses 23, and is provided with a lateral stem which extends through a slot in the side of the casing, in which the locking and firing devices are inclosed, the said stem being set at safe, as shown in Fig. 2, and the unsafe or firing po-' sition, as shown in Fig.

The numeral 25 indicates the sear spring the lower leaf of which bears against the tail of the sear, as shown, and the end of the upper leaf sets under the safety block, as shown in Figs. 1, 2 and 3 of the drawings, thus serving the double purpose of pressing the tail of the sear against the hammer and holding the safety block (after manipulating the said safety block, to either the firing or safety position through the medium of the button attached to the stem), in a set position.

It will be understood that the sear spring is provided with two lower leaves, one for each set of firing devices, in a double barreled gun, and an upper leaf for engagement with the said safety block.

Referring to Fig. 4 of the drawings, the numeral 26 indicates the bolt for locking the barrel. It is located longitudinally under the barrel at the breech,and is slotted longitudinally at its fore end, the rear wall of the slot being beveled to allow the rear locking lug to throw it back automatically when returning the barrel to normal or firing position. The said lug is provided with a shoulder- 28 at its rear which is engaged by said bolt to lock the barrel, being assisted by the pivot or hinge lug 29, which is provided with a shoulder 30 which is engaged by the fore end of the bolt when set forth. The bolt is provided with laterally-projecting pins 31, between which sets the short arm of an angle lever, which is fulcrumed in the metallic frame of the fore part of the stock, as indicated by the numeral 32. The long arm of said lever extends rearward and, at its end, is provided with a lateral stem or projection which extends through a curved slot in the side of the metallic case at the fore end of the stock and the outer end of the said stem is provided with a button or knob 83 by which the lever maybe manipulated to draw the bolt back to unlock the barrel. Under the long arm of the lever is located the spring 34 of any suitable construction which presses it upward so as to cause the bolt to move forward when the button or knob is released.

In the modification shown in Fig. 5 of the drawings the lever is dispensed with and in its place a sliding block 35, having an inclined lateral rib 36, is employed, as shown by dotted lines. or lugs, 37, at the rear end of the bolt and the block has a stem which projects through a vertical slot in the metallic ca sing at the fore end of the stock, the outer end being provided with a knob or button by which the block may be moved up or down to shoot or draw the bolt.

In Fig. 6 of the drawings the numeral 26 represents the locking bolt, 22 the safety block in its forward position suitably secured in the breech block, 18, the upwardly-projecting portion of the trigger, and 43 a set screw secured to the safety block and so arranged as to project from said block a suitable distance in order to intercept the locking bolt as it is being withdrawn to unbolt the barrel, the operation being thusz-As the action bolt is withdrawn, it comes in contact with the set screw, which, in turn, will push back the safety block, thereby causing the latter to move to the safe position, as shown in Fig. 2. \Vhen the invention is applied to a doublebarreled gun, it is evident that the firing devices must be in duplicate.

The operation of my invention will be read ily understood from the above description in connection with the drawings, and is as follows: The parts being in the position shown in Fig. 1 of the drawings, to break down the barrel the bolt is drawn back by operating the lever. Upon turning down the barrel so as to elevate the breech for the insertion ofa cartridge the lateral projection let on the barrel lug will elevate the fore extension of the hammer, throwing it back until the projection or shoulder 15 is engaged by the fore end of the sear which is thrown into engagement The said rib sets between two studs automatic.

by the spring. After inserting the cartridge the barrel is returned to its normal position and locked. The gun is then in position for firing and the hammer when in this position may be locked by pushing the safety block back so as to set over the rear end of the trigger, the upper leaf of the spring passing from the forward to the rear recess at the lower edge of said safety block. By pushing the block forward the trigger is free to be operated to discharge the gun. When the firrn'g nose of the hammer is in contact with the cartridge, the fore extension of said hammer has passed and is beyond the cooking lug, but after striking, the upper leaf of the main spring which is stronger than the lower leaf, causes the hammer to rebound into position to be engaged by the cocking lug in order to cock the hammer, upon again breaking down the barrel to re-charge thegun.

It will be seen from the above thatthe locking and firing devices are wholly incased, and if desired, the stem by which the bolt locking lever is operated, may be provided with acurved plate adapted to fit flush against the curved slot of the lock casing, so as to keep the slot closed, and prevent the entrance of dirt or moisture, as shown in Fig. 4. It will also be understood that the safety button is so arranged as to fit close against the outer surface of the gun in order to prevent the entrance of foreign substance or moisture.

By the construction, as illustrated in the drawings,it will be seen that the barrels may be readily attached to the gun stock regardless of the position of the hammers, for instance, should the fore extension of the hammer be in the position shown in Fig. 1, on at taching the barrels to the stock, the lug 14 will describe a portion of a circle, as shown in Fig. 1, carrying with it the said fore extension of the hammer, which in turn, also describes a portion of a circle, until they reach the point of separation, whereupon the upper arm of the main spring will serve to return the said hammer to the rebounded position and the lug will rest in a position to automatically cook the gun upon the breaking down operation.

Should the hammer be in acocked position when it is desired to attach the barrels to the gun stock, as shown in Fig. 2, theinclined surface of the lug will come into contact with the end-portion of the fore extension of the hammer, and on describing a portion of a circle, as before referred to, will force said fore extension slightly upward, allowing the lug to pass and thus assume its normal position, as hereinbefore described.

It will be readily understood that, if desired, the set screw shown in Fig. 6, may be entirely removed from the safety block, or screwed so far into the same as to prevent it from coming in contact with thelockingbolt during the operation of the withdrawal of the latter, thereby rendering the safety block nonlt is obvious that certain slight changes in the construction and arrangement of the parts may be resorted to without departing from the main features of my invention.

I am aware that the locking levers may also operate directly or through the medium of a transverse or longitudinally-movable bolt, on a top extension carried by the gun barrels.

It will be seen that while attaching the barrels to the stock, the hammers will not come in contact with a cartridge, should there be --one in the barrels at thetime.
