GUN-LOCK.

SPECIFICATION forming part of Letters Patent No. 468,853, dated February 16, 1892.

Application filed January 10 1890. Serial No. 336,530- (No model.)

To aZZ'whom it may concern:

Be it known that I, GEORGE W. WERNER, a citizen of the United States, residing at Lancaster,in the county of Lancaster and State of Pennsylvania,have invented certain new and useful Improvements in Gun-Locks as an Article of Manufacture; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in gun-locks of the ordinary pattern known to the trade; and the Object of my invention is the production of a gun-lock as an article of manufacture, constructing it cheaper and yet in better form than is the one nowin common use.

The details of my invention consist of, first, an improved lock-plate, in which I dispense with the two holes or recesses heretofore used to receive and hold the integral side lugs or points of the main and sear springs; second, a mainspring without the usual side lug to keep it in place, also without the usual bifurcated tip third, a tumbler having a solid lever in place of the slotted one, to which the -'swivel was formerly pivoted; fourth, a rectangular link to connect the tip of the mainspring with the forward end of the tumblerlever instead of the -shaped swivel in former use; fifth, an improved bridle; sixth, a searspring without the usual side lug to hold said spring in place,'and, seventh, a washer and common round-head screw in place of the usual flat-headed English screw to hold the hammerto the [lend ofthe tumbler-trunnion.

In the accompanying drawings my invention is clearly illustrated.

Similar letters and figures refer tosimilar parts throughout the several views.

Figure 1 is a full inside elevation of a gunlock embodying the elements of my invention; Fig. 2, a top View of Fig. 1,the hammer, screw, and washer removed; Fig. 3, a cross-section through the line 10 w in Fig. 4, viewed from the left; Fig. 4, a cross-section through the line a z in Fig. 1, viewed from the right; Fig. 5, an inside view of the lock-plate in Fig. 1, with all the working parts removed; Fig. 6, a side viewof Fig. 5 viewed from below; Fig. 7 a View of the bridle turned over end for end, as

it appears in Fig. I viewed from below; Fig. 8, a top view of Fig. 7 Fig. 9, a top view of the tumbler detached from Fig. 1; Fig. 10, a top view of Fig. 9; Fig. 11, plan views ofthe screw and washer used to hold the hammer to the El end of the tumbler-trunnion; Fig. 12, plan and side elevation of the link used to join the tip of the mainspring to the forward end of the tumbler-lever; Fig. 13, top view of the mainspring detached from Fig. 1; Fig, 14, top view of the sear-spring detached from Fig. 1, showing the retaining-screw in place.

A plate A-shaped, as shown in Figs. 5 and 6, forms the base of my invention. Along the upper edge near the rear end, on the inner face of this plate and integral therewith, is a raised point or projection 0;, adapted to engage the back of the sear-spring, keeping it in place to perform its proper action upon the sear, as will hereinafter more readily appear.

1, 2, and 3 are holes threaded and adapted to receive the end of screws, as will hereinafter be shown.

at is a larger hole adapted to receive the action of the large trunnion of the tumbler to be described.

A is an angular elevation along the upper' edge, adapted to be recessed to receive the nipple arm or tube of the gun-barrel. In the under edge of this elevation A is a recess a, adapted to receive and keep in place the sharpened point of the turned-up end of the mainspring, to be hereinafter described. Near the forward end of this plate and rigidly attached thereto is a pin A adapted to pass through the loop or fold of the mainspring referred to, holding its rear end in place.

B is a tumbler shaped as shown in Figs. 9 and 10. b and b are trunnions of different diameters placed on opposite sides thereof, having their centers on the same axis; 1), the smaller, being adapted to engage and turn in a hole 5 in the bridle, to be hereinafter described, and b, the larger, adapted to engage and turn in the hole 4 of the plate A, before mentioned. The trunnion 1), extending through the body of the plate A, has its forward end I) made angular and adapted to enter and engage the angular orifice in the end of the hammer-stock and having along its axis a hole threaded to engage the screw adapted to hold. the hammer thereto.

6 and '7 are notches adapted to engage the toe of the sear when the hammer is cocked.

b is a shoulder adapted to engage the base of the bridle to s op the downward motion of the tumbler against the action of the mainspring when the same is in operation.

13 is a solid arm orlever somewhat thinner than the body of the tumbler, centrally located, and having in the upper side, near its forward end, a notch b adapted to receive and hold the link, yet to be described. The tumbler B and all its parts, as described, form one body or piece.

C is a bridle made of one piece and shaped as shown in Figs. 7 and 8, consisting of two portions 0 and c. The portion 0 forms the base and is adapted to rest against the plate A. The portion 0 forms the top and is adapted to extend over the tumbler, the scar, and the looped end of the sear-spring, Fig. 1. The portion a is raised from the portion 0 far enough when the bridle is in place to form a recess to receive the tumbler, the scar, and sear-spring, allowingfreedoin of action to the tumbler and sear. The perpendicular wall a is adapted to come in contact with the shoulder b of the tumbler B and stop the downward progress of said tumbler, as mentioned.-

Through the portion 0 are holes 8, 9, and 10, corresponding, respectively, with the holes 1, 2, and 3 through the plate A, the hole 8 continuing through the portion 0.

In Fig. 13 is shown in full top view a main spring D folded over, as shown in Fig. 1, so as to form a loop or eye (Z, adapted to receive the pin A of the plate A, keeping this end of the main spring fixed when said spring is placed in position. The folded portions D and D of said spring come together at a point 11. One portion, as D, has its extremity forged thin, turned up and sharpened, forming the point cl, adapted to enter the recess a and held in place thereby, asbefore mentioned, and the other D extending forward to a point below the lever B of the tumbler- B. Fig. 1 has its extremity narrowed and curved, forming underneath the notch d adapted to engage and hold the lower bar of the connecting-link, yet to be described.

E is a rectangular link. (Shown in plain front and side elevation in Fig. 12.) This link is punched entire from a thin plate of sheet metal and is adapted to connect the forward end of the mainspring D by engaging the notch 01 on the under side of the tip thereof to the forward end of the tumbler-lever B by engaging the notch 19 as described and shown in Figs. 1, 2, 3, and 4..

F is a sear-sprin g made of a straight strip of spring metal, having an eye at one end through which a screw serves to holds it in place. A top View of this spring is shown. in Fig. l t, together with the retaining-screw through its eye. This spring is shaped and placed as shown in Fig, 1. Its back near the looped end,

resting against the point a, before described, is held in place thereby, so that the point of said spring bearing against the back of the sear, as shown, will impart to the sear the proper pressure.

The sear being of the ordinary well-known pattern is not here described.

In Fig. 11 are shown plan views of a washer G and a common round-headed screw H used in combination in place-of the large fiatheaded English screw to hold the foot of the hammer to the angular end 6 of the tumblertrunnion b, as shown in Figs. 3 and 4.

Now all the parts, as described, being placed in position on the plate A, asis indicated in Figs. 1, 2, 3, and 4, the bridle C so that the holes 8, 9, and 10 therein will correspond, respectively, with the holes 1, 2, an d3 in the plate A, it will be readily seen that the screw g, passing through the portion 0, serves to hold the bridle O firmly to the plate A; that the screw h, passing through the loop or eye of the sear-spring, serves to bind the parts together at this point, keeping the searspring in place, and that the screw 2', passing through the sear, holds this end of the bridle and serves as a pivot, on which the sear acts. It will also be readily observed that the point a, bearing against the back of the sear spring F, serves to keep the point of said spring permanently against the back of the sear, compelling positive action. Again, that the pin A passing through the loop (Z in the folded end of the mainspring D, serves to hold the said spring in place at this point, and the sharpened point (1, entering the recess a in the elevation A, serves to keep this extremity of the mainspring in place, and that the link E, engaging the notch d in the under side of the curved tip of the mainspring and the notch b in the upper side of the forward end of the tumbler-lever B, serves to securely connect the mainspring D to the tumbler l3, imparting to said tumbler full and complete action, and, also, that the washer G and the screw H, tapped into the angular end I) of the tumbler-trunnion b, in combination with said washer G, serves to hold the foot of the hammer firmly to the tumbler 13, Figs. 3 and 4, the screw and washer taking the place of the large flat-headed English screw so well known.

I am aware that devices similar to mine have been used heretofore in the mechanic arts; but I am not aware that any of them have been used in the manner and for the purpose I propose. I therefore do not claim them nor any of them, broadly; but
