465W V Z (f; a I 4111mm? HEN-RY H. TALBOT, on ST. JOSEPH, MISSOURI.


Specification of Letters Patent.

Patented March 24, 1908.

Application filed October 30,1906. Serial N 0. 341,298.

To all whom it mag concern:

-Be it known that I, HENRY H. TALBOT, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Firearms; and- I do 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, reference'being had to the accomganying drawings, and to the letters and gures of reference marked thereon which form a part of this specification.

The objectsought by me in this invention is to rovide a firearm of symmetrical design,

simp e construction, absolute safety from accidental or unintentional discharge, which may be fired instantly without any further manipulation than grasping the handle and pulling the trigger and which will ermit of construction in large as well as sma calibers without loss of symmetry or practicability.

My object is attained by means of: first: a shortened breech-block with its accompanying firing-pin and spring, which is of only suflicient ength'lto entirely cover the magazine and extend back over the maga- I ger lock which, when the action is closed,

zine guide lugs.

Second: a complete clearance' of the frame to provide an unobstructed path for-the hammer. Third: a hammer of such novel construction of 'its shank and head as will ShOlteIl'lts radius and lace it in a more forward position within t e frame reducing the over-all projection in the rear of the arm above thecurvature of the handle to a minimum, thus ermitting a jacket to be thrown over it. t is notched in sucha manner as will permit of positive retention in a cooked position, when desired, by a safety, clutch. Fourth: an

automatic safetyv of such construction thatitwill clutch and restrain the hammenwhen it is cocked at all times until pressure is brought to bear upon it by the hand grasping the handle, when it is automatically retracted, freeing the hammer. Fifth: a trigpermits a free movement of the trigger and allows it to actuate the sear; but which, the instant the action opens, obtains powerful and mechanical possession of thetngger, regardless of any pressure which is exerted by the finger, and returns it to its "forward position, there looking it from contactwith the sear until .the action is again closed and ready to be operated. I accomplish my ob ject by the mechanism illustrated in the accompanying drawings, in which,

This recess is such that its forwar wall is an incline which in the rearward movement'of the carriage Wipes upon the head of the .trig er lock bar, gradually depressing it until the gill metal of the carriage rail contacts,holding it fully depressed until'the carriage returns,

permits it to rise until it is ful y seated therein.

Looking at the rear end of the a right and cam to enga e with the grip-bar E by arm when the safety head is in this position, it resents a smooth surface, lining with the wa of the frame and end of the carriage, perfectly. The inner dotted lines show the head when the hammer is downand there is no pressure exerted on the grip-bar. In this position. the head recedes slightly into the frame, suchrecession being limited'by the shoulder of the grip-bar striking the frame, thus offering an indication as to the position of the hammer. The outer dotted'lines show the'position of the head when pressure is being exerted on the grip-bam'in this 'position the head projects from the rear walls of the frame; (1 is the clutch pawl on the safety head for the purpose of engaging restraining notchQc, in the hammer head.

J is the ejector which operates in a known manner, is of known construction, with the exception of an extension thereto which'is provided to recess into'a wall of the frame in such a manner gtha-t it lines therewith and offers no interior obstruction; 9' is the beveled extension provided on the ejector for admis-' sion into a beveled recess provided in the frame for the purpose of giving bearing surface for a retaining screw passed throughthe perforation, a, in the left wall of the frame. This extension is so shaped that when it is in place, it lines with the inner wall and forms the left hand magazine guide lug; y" is a threaded perforation in the extension j for the purpose of receiving a retention screw passed through the left wall of the frame as shown by a It will be understood from the foregoing description that the combination set forth is intended for the advancement of parts to economize on space in the rear of'the magazine channel above the curvature of the handle which space if practical a small arm {like a pistol, especially if constructed inlarge calibers, is very limited and of utmost importance: it will be readily seen thatiif a relatively thin casting be left in'the frame it the top and rear of the magazine channel anda slight change made in thehammer shank the object in view would be partially attained without in any material way departing from the spirit of this invention.

It may be in the application of this invention slight deviationsfrom the construction described and shown would while obvious be deemed byme the more desirable; therefor I would have it understood that I do not wish to restrict myself to the specific con:

struction shown, but reserve the libertyfor' such departures asfairl y fall with n the spirlt and scope of my lnvention.

companying drawings relate particularly to the mechanismv of a pistol it will be understood that I do not confine myself to its use in such firearm only, but desire to cover a similar construction, either in part or combination, in any firearm.

1. The combination in a fire arm with a carriage which contains a breech block, an extractor, an ejector, a reciprocating barrel, a recoil spring seated beneath the barrel, a magazine, a main spring, a sear, a sear trigger and magazine catch spring and a magazine catch, of a frame'provided with a slot through that portion of it immediately in front of the magazine channel and above the trigger slot which intersects a hole drilled in the right wall for the reception of a trigger lock, -a slot in the rear and center of the handle for the reception of a grip bar, an open rear end above the curvature of the handle forv the reception of a, safety head, a beveled recess in the left wall immediately in the rearv and at the top of the magazine channel for thereception of the ejector extension, an open and unobstructed path for the hammer to the magazine channel, a hammer, the upward and forward bending shank of which bears the entire'head forward of a line vertical with the'pivotal center of the hammer tumbler, a notch in-the top ofthe hammer, an

automatic grip bar, a spring attached thereto and a bearing pin thereon, an automatic safety head ada ted to interlock with said grip bar and cutch the hammer and to restrain said .hammer when cooked until pressure is brought upon it by'the hand grasping the fire arm handle, a trigger provided with a notch, a guide and bearing roll, a

3. In a firearm the= combination-with the frame of an; automatic safetyhead in line with and forming apart of the frame, a pivoted hammer,. a notch in the top thereof and a clutch pawl in the-safety. head to engage therewith, a grip-bar proyided with a slot, and a rockercam on said safety head' extension on saidhead forming alclo sed joint with the frame; and .the grip-bar from the end of which said curved'end receives mo- 7 tion for the head-when the hammer is down,

and the shoulder in the frame by contacting with which the outward motion of the head is restricted, substantially as set forth and shown.

4. In a magazlne pistol the combination witha frame having a recess in the inner left wall at the top and immediate rear of the magazine channel and an ejector mounted on ;the top of the frame, of an extension on said ejector adapted to vertically enter said recess and fill it making'said frame wall continuous and offering no interior obstruction in the I-firame,- substantially as described and shown.
