GUN-LOCK.

SPECIFICATION forming part of Letters Patent No. 782,899, dated February 21, 1905. Application filed March '7, 1904. Serial No. 1917,056.

To all whom, t may concern,.-

Be it known that I, BARNUM L. CLEVELAND, of Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Gun-Locks, of which the following' is a specification.

My invention relates to gun-locks applicable to single or double barrel guns or to repeating-guns; and the object thereof is to provide a gun-lock which is particularly simple and effective in construction and highly efficient in operation.

To this end the invention includes the combination and arrangement of component parts to be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate one embodiment of my invention, Figure 1 shows a portion of a gun in section with the lock mechanism in elevation, showing the parts in the position assumed thereby when the hammer is cocked and tension placed on the mainspring. Fig. 2 is a similar view. showing the parts in the position assumed thereby when the hammer is down just after the firing of the gun. Fig. 3 is asimilar view showing the parts in the position assumed thereby when the hammer is cocked before tension is placed on the mainspring. Fig. 4

is a perspective View of a portion of the cocking and spring-tensioning means, and Fig. 5 is a detail.

The improved gun-lock includes,essentially, a hammer, a mainspring, a trigger, and means for cooking the hammer, while relieving substantially all tension from the mainspring, and thereafter tensioning the mainspring.

A gun-frame is shown conventionally in the accompanying drawings, the same being designated by the letter A, having a recess therein -in which the hammer ais pivoted upon a trans- To cock the hammer and tension the mainspring, means are provided working within the stock and having a hand-operated part projecting below the same to the rear of the trigger. This means includes a reciprocable slide 0', having one or more finger-engaging openings below the stock and a pivoted tensioning arm or strut s.

The slide fr is provided with a fiat face ar-v ranged below and intended to find a bearing against the under side of the frame, from the rear end of which slide a lug L projects through a slot in the bottom of the frame and is provided with a bearing-roller u. Within a recess in the front portion of the slide r the lower end of the arm s is pivoted, the latter being pivoted intermediate of its length to the frame through the intermediary-of a pin o, carrying a roller which Works within a curved longitudinally-extending slot w in said arm. The upper end of the arm s coacts with the intermediate portion of the mainspring c and is preferably provided with a roller-bearing.

Depending from the lug on the hammer is a double link y, to the free end of which the forward end of a cooking-armaY is connected, the rear end of the latter resting upon the bottom Wall of the recess in the frame and is bifurcated to straddle the arm s and lug if said arm .fr is of suflicient length to extend to the latter. The arm o@ is preferably constructed of material having some flexion, so that it will act in the capacity of a spring.

Journaled upon opposite sides of the arm s are rollers Z, which coact with the free end of thel cooking-arm .fr to depress the same when the slide r is moved forward, as will be hereinafter described.

In the operation of my improved gun-lock, assuming that the hammer is down, as shown in Fig. 2, when the slide fr is moved forward the arm. s will be tilted, as shown in Fig. 3,

IOO

thus releasing all tension from the mainspring c, while the free end of the arm .fr will be depressed, causing said arm to pull down upon the link 1/ and therethrough draw back the hammer n until the nose o on the trigger m, interlocks with the shoulder p. The interengagement of said nose u and shoulder p will maintain the hammer in cocked position. At the time when the slide l' occupies its forward position there is not sufficient tension upon the spring c to throw the hammer forward, even though the trigger should be operated either accidentally or intentionally.

To tensi'on the spring c, the slide r is moved back to its startingposition, as shown in Fig. l, bringing the bearing-points formed by the upper end of the arm s and the rollers substantially in line with the pivot-roller w, and thereby pressing the central portion of the spring c upward.

Should it be desired to release the tension from the spring to hold the parts at safety,7 it is only necessary to move the slide r forward, which atonce removes all tension from the spring c without shifting the other parts of thel mechanism. This can be accomplished without removing the gun from the shoulder and tension put on while bringing the gun up to the shoulder to shoot.

The construction and operation of my invention will be readily understood upon reference to the foregoing description and aocompanying drawings, and it will be appreciated that the parts and combinations recited may be varied within a wide range without departing from the spirit and scope thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a gun-lock, the combination with a hammer, a trigger, and a mainspring, of means for cocking the hammer while substantially the entire tension is off the mainspring, and thereafter tensioning the latter, said means comprising a slide having' a finger-operating part and a pivoted arm, substantially as described.

2. In a gun-lock, the combination with a hammer, a trigger, and a mainspring', of' means for cocking the hammer while tension is entirely off the mainspring, and thereafter tensioning the latter, said means comi prising a cocking-arm, a tensioning-arm, and a slide provided with an operating part located upon the outside of the breech, said slide being connected to the tensioning-arm, substantially as described.

3. In agun-lock and in combination, a hammer, a trigger coacting' therewith, a mainspring held at one end andcngaging the hammer at its free end, a slide, an arm pivoted intermediate of its length in the stock and coacting at its upper end with the mainspring, a pivotal connection between said arm and the the first arm coacting with said cocking-arm for operating the latter as the first-named arm is shifted, substantially as described.

4. In a gun-locl and in combination, a hammer, a trigger coacting therewith, a mainspring held at one end and engaging the hammer at its free end, a slide having finger-engaging means beneath the stock, a tensioningarm slotted centrally, a pin in the stock having a roller-bearing working in said slot, a roller-bearing at one end of said arm engaging the mainspring, a pivotal connection between the other end of said arm and the slide, a setting-arm connected to the hammer at one end, and rollers on said tensioning-arm engaging the free end of the setting-arm, substantially as described.

5. In a gun-lock and in combination, a hammer, a trigger coacting therewith, a mainspring held at one end by a roller-bearing and engaging the hammer at its free end, a slide having linger-engaging means beneath the frame, and a lug working in a slot in the latter and having a roller-bearing in the frame, a tensioning-arm slotted centrally, a pin in the frame having a roller-bearing working therein, a roller-bearing at one end of` said arm engaging the mainspring, a pivotal connection between the other end of said arm and the slide, a spring hammer-setting arm, a link depending from the hammer, a connection between said link and one end of the hammer-setting arm, and rollers on the tensioning-arm coacting with the opposite end of said hammer-setting arm, substantially as described.

6.

' setting-arm connected to the hammer at one end, and means on said tensioning-arm engaging the setting-arm, substantially as described.

7. In a gun-lock and in combination, a hammer, a trigger coacting therewith, a mainspring held at one end and engaging the hammer at its free end, a tensioning-arm coacting with the mainspring, a setting-arm coacting with the hammer, and a slidehaving {ingerengaging means beneath the stock and operatively connected to both the tensioning-arm and the setting-arm, whereby in the movement of the slide in one direction both of said arms will be acted upon substantially as described.

8. In a gun-lock, a hammer, a cocking element, a mainspring coacting with the hammer, a slide provided with a part located on the outside of the breech, means actuated by the slide for controlling the tension of the mainspring and for actuating the cocking eleslide, a cocking-arm, and a part carried by ment, substantially as described.
