DROP-DOWN SMALL-ARML Specification of Letters Patent.

Patented Feb. 11, 1908.

' Application filed June 15. 1907. Serial No. 379.185.

To all whom it may concern:

Be it known that I, WILLIAM BAKER, subject of the King of Great Britain, residing at 87 Snow Hill, Birmingham, England, have invented certain new and useful Improvements in Drop-Down Small-Arms, of which the following is a specification.

This invention relates to improvements in drop down small arms, and refers to improved means in connection with the cocking of the hammer, by which when the gun is opened the hammer is put to cook, but lies under practically no spring pressure, but upon the closing of the gun the hammer is put under the necessary main spring pressure for firing.

I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows this my invention as seen when the gun is closed, while Fig. 2 shows the arrangement as seen when the gun is opened, in both cases the front portion of the lump upon the barrels being made to operate the working parts. Fig. 3 is a detached side view of the spring box lever the same being reversed to that shown in Figs. 1 and 2 so as to show the position of the spring; Fig. 4 being a plan view of the lump lever shown in Figs. 1 and 2. Fig. 5 is a further view of this my invention similar to those already described, except that the lump lever is made to engage with the second or rear part of the lump upon the barrels. Fig. 6 shows a modified arrangement of the position of the spring box lever, and of the lump lever; Fig. 7 being a plan view of the said modified form of lever. Figs. 8 and 8 show a modified form of the main spring box lever, and the spring, by which the hammer may be put to cock, Fig. 8 showing the action under pressure ready for firing, while Fig. 8 shows the action merely put to cook.

In carrying out this my invention I carry the main spring 9 in a box or carrier 10, said box being pivoted at 11 to the lock plate 26, andtherefore having a lever-like movement,

and which I will now term the spring box lever 10. The said spring in those forms of the invention shown in Figs. 1 to 6 inclusive, is inserted in a recess extending inwardly from one side of the lever and is attached to the lever 10 by the peg 9 a in the well known manner, that is to say, by the peg 9 upon the side of the said spring passing into a corresponding hole made in the side of the said lever.

The longer end of the main spring 9 engages in a notch or opening 12 formed in the rear side of the hammer 13- The forward end 14 of the spring box lever extends along the side of the said hammer, where it is operated upon by the end 15 of the lever 16, which is pivoted at 17, and which I will now term the lump lever. This lever 16 is arranged as follows :It is well known that openings or slots are made in the body 18, into which the

lumps

19, 19*, upon the end of the barrels 20 may enter, and in this my invention I further cut away the metal of the body from the lump 0 ening (for 19*) rearward, and in the space t us provided I pivot the aforesaid lump lever 16, whose forward end comes in contact with the lump 19 on the barrels when the gun is being closed. The rear end 15 of this lever is arranged upon each side to engage with the aforesaid extended end 14 of the spring box lever 10 in such a manner, that when the gun is closed (as seen in Fig. 1) the said lever 10 is raised, and the spring 9 thereby put into compression; and of course when the gun is open, the said lever is free, that is to say, it exercises no influence upon the spring 9. Again, at the rear end of the spring box lever 10 I provide a (double limb) sear spring 22, the end of the one limb being notched into the rear end of the spring box lever at 23, so as to exercise a small force thereon, which shall lightly press the fore end 14 downwards (as seen in Fig. 2). The lower longer end of the sear spring rests upon a fixed peg 24, in order to give the spring force thereto. The forward double part of the sear sprin is made to rest upon the sear lever 25 in or er to keep it in bent with the hammer 13 in the usual manner; thus this form of spring performs two purposes, that is, acting as a sear spring, and also operating the spring box lever.

On reference to Fig. 5 it will be seen that the lump lever 16 is made to rest against the lump 19, thus showing that it may be operated by either the

part

19 or 19 the other parts of the mechanism being as before described.

Upon reference to Fi 6 it will be further seen that the position 0% the spring box lever 10, with its spring 9, may be varied without interfering with its action upon the hammer 13, so as to accommodate the varying forms of gun lock mechanism. In this case the lump lever 16 is shown as being operated by the front portion 19 of the lump, While the keeping it in bent.

ends 15 acting upon the spring box lever 10 compress the spring 9 so as to act upon the hammer 13 in the manner aforesaid.

It will be quite clear that although I have described the spring 22 as constructed in the manner shown, and performing the two uses of operating the spring box lever 10, and the sear lever 25, I may if desired employ other forms of springs for acting upon the sears.

On reference to Figs. 8 and 8 it will be seen that the main spring 9in conjunction with the spring box lever 10may be made to serve merely to put the hammer to cook, (that is to say, that while in this position there is no pressure towards firing acting upon the hammer). This is effected as follows:The lever 10 is pivoted at 11 as before, but instead of being connected direct to the lever 10, as before stated, the peg 9 upon its side is passed into a corresponding hole made in the lock plate 26 at the side, so that both the lever 10 and the spring 9 in this case are pivoted to the said plate. It will also be noticed that the recess or opening made in the said lever 10 to receive the spring 9 extends through from side to side of the lever and is made somewhat wider to accommodate the action of the said spring the wider or larger opening in said lever permitting the latter and the spring limited ranges of movement about the

parts

11 and 9*, respectively, as centers. Hence the said spring, (as seen in Fig. 8*,) when under no action from the lump lever, tends of itself to bring the lever 10 downwards, and so puts the hammer into bent, there being in this case any ordinary spring action made to act upon the sear for When however the lump lever is acted upon as before described, so as to raise the lever 10 (in the manner shown in Fig. 8,) then the full force of the now compressed spring 9 is brought to bear upon the ammer ready, for firing,

The action of my invention is therefore as follows :Upon the opening of the gun after firing, the spring box lever is moved under spring action so as to cause the hammer to be ut into bent. By now closing the gun, the ower side of the lump (upon the barrel) presses down the one end of the lump lever, which acts upon the spring box lever so as to ut the main spring into action ready for ring. If the gun is opened without firing, the spring box lever is also brought into a position of inactivity, under spring action, and also by which, as before described, the hammer is put into bent.

What I claim as my invention and desire to secure by Letters Patent is 1. In fire arms of the class described, the combination with a gun frame, and a relatively pivoted barrel, of a hammer mounted in the frame, a main spring carrier movable independently of the hammer, a spring cooperating With the hammer and serving to 2. In mechanism of the class herein referred to, the combination with the hammer 13, sear lever mechanism, and main spring 9, of the spring box lever 10 pivoted to plate 26, and having the spring pivoted to said lever at 9 the said lever being operated in its downward movement by a spring, such as 22, at its one end, and operated at its other end in its upward movement by a lever operated from the barrel lump, all as set forth and shown, and for the purposes specified.

3. In a fire arm of the class described, the combination with a main frame, and a barrel mounted in pivotal relation therewith, of a hammer mounted in the frame, a main spring carrier pivoted independently of the hammer, a spring mounted in the carrier and cooperating with the hammer, and a device operable when the barrel is moved into one position to turn the carrier and cause the spring to set the hammer in cocked position, and serving to move the carrier to tension the spring when the barrel is moved to a different position.

4. In a fire arm of the class described, the combination with a main frame, and a barrel pivoted thereon, of a pivoted hammer on the frame, a main spring cooperating with the hammer, a spring carrier inclosing the spring and serving to operate the spring to move the hammer toward cooked or fired positions,

and a device controlled according to the relative position of the main frame and barrel for actuating the spring carrier. 5. In a fire arm of the class described, the combination witha main frame, and a barrel pivoted thereon, of a hammer on the main frame, a spring carrier independent of the hammer and having a recess therein, a main spring inserted in said recess having an arm arranged to abut against a portion of said carrier, and its opposite end cooperating with the hammer, a movement of the carrier in one direction causing the spring to set the hammer in cocked position, and a movement of the carrier in a reverse direction serving to tension the spring.

6. In a fire arm of the class described, the combination with a main frame, and a barrel pivoted thereon, of a hammer carried by the of the carriersetting the spring under tension for firing, and a device controlled according to the relative position of the frame and barrel for actuating the spring carrier.

7. In a fire arm of the class described, the combination with a main frame, and a barrel movable relatively thereto, of a hammer on theframe, a spring carrier pivoted on the frame independently of the hammer and having a recess, a main spring confined in said recess and cooperating at one end of the hammer, and an actuating lever controlled according to the relative position of the main frame and barrel for moving the carrier to relieve the tension on he spring and cook the hammer when the barrel is in one relative position, and to tension the spring when the barrel occupies a different position.

8. In a fire arm of the class described, the combination with a main frame, and a barrel movable relatively thereto, of a hammer mounted on the frame, a pivoted spring carrier also on the frame having a recess therein, a main spring fitted in the said recess having one end cooperating with the carrier and its opposite end cooperating with the hammer for moving the latter to cooked and fired position according to the position occupied by the carrier, a lever controlled according to the position of the barrel for moving the carrier into two positions, and a spring cooperating with the carrier for retaining the latter in cooperative relation with the said lever.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM BAKER.
