Application ned August 24, 1900. saranno, 27,885. ci@ man.;

resident of Chicopee, in the county of.Harnp-.

den and State of Massachusetts, have invented certain new and useful Improvements in Extractor Mechanism for Firearms, of which the following is a full, clear, and exact de-- scription.

rThis invention relates to improvements in itne extractor mechanism for a shotgun or other firearm of the breakdown class.

The object of the invention is to provide an extractor of entire eiciency which is composed of a minimum of very simply constructed and durable parts,`te the end of cheapness,v ease of assemblage and adjustment, and'free' dom from derangement.'

The invention consists of the constructions and combinations of parts, all substantially' as hereinafterv fnily described,and set forth in the claims. y,

Reference is to be had to thev accompanying drawings, in which- Figure l is Vin substance a central View extractormechanisin is comprised, the breech being shown open, while Fig. 2 is a similar sectional view, but showing the breech closed.

inthe drawings, A represents the frame of the gumicomprising the forward extension A3, to which the bottom lug B ofthe barrel or barrels is jointed at d, as usnai. The bottom lng B under the barrel is provided with the longitudinal bore or socketb, extending therethrough from end to end. rihe forward end4 p .of the bottom lug terminates at a little dis tance to the rear of the joint-pin d. -C represents the extractor or ejector, the stem f of which isitted aud'plays longitudinally in the aforesaid bore b,`said stem being of a length less than that of' the said bored, 'bottom lug, so that the ,forward .end of the stem terminates somewhat to the rear of the to exert a crowding rearward action against forward end of `the bottom lng, leaving the space for occupancy of the spiral spring g, the rear end of which is in bearing against the forward end of the ejector-stem, operating said stem while the forward end of the spring isin abutment against the vertical part h of the single piece or device D, which comprises the latch or catch for the ejector'and also a lever extension by meansof which the said. catch hasits releasing movement imparted thereto. lower portion recessed at' z', and from this rej, which communicates with the socket or bore b. 4

The

tion 101of`the' said 'integrally-formed device has its position beneath thevjoint-pin d and is pivoted atn to opposite' members or cheeks of the bottom lug, between which the foi- Ward part of the said device D is ttedl AThe 'forward end portion of the frame extension A2 has thethickened portion ornose per forwardly-extending'member 13 of the device D. This nose isformed with a screwthreadcd socket p, in which thefscrew-plug is provided, the point or extremity of whic screw-plug constitutes an adjustable contact member for the extension ory part 13.

s represents a limiting-pin.screw-threading through a rear-portion of the bottom lug and having its point entering in the groove'tiu the under side-of .the ejector-stem, this pro- `vision"serviug to prevent the extractor from being thrown out from the socket b in case the 'gun should be broken down so far as to leave the ejector clear above the breech'u.

sitio shown in the drawings to the position in readiness for tiring, the ejector is by its impingement against the vertical forward face of the breech and in a usual manner forwardly forced to occupy the position of its The bottom lug has its forward The aforesaid device D is constructed in the tension 13, projecting forwardly from the upforward extremity lft'of the lower main por-l cess extends the upwardlyleading aperture,

ejector proper, C, within the 'recess o ando'r' its stem in such a forward position as to have its'catch-notch m advanced toa point aila- 0 down swinging ofthe barrel also carries the forward end of the part 13 away from the n pper innerend of the screw-plug q, so that the device D as a whole may havea swinging movement. from its pivotal point of connection with the bottom lng and as insured by the spring g in compression between the forward end of the ejector and the rearward vertical face of the upstanding part h, so that the catch 12 will engage in the catch-notch m. Now, reversely, when the gun is broken down or opened the said integral device D, moving bodily in unison with the barrel boty tom lug and relatively to the frame exten-l sion A2 and coming to contact against the abutment-plug q, causes after the` gun has been suiiiciently opened to render theopera- `tion of the extractor desirable the swinging of the device D relatively to the barrel-lug, whereby its catch member becomes freed from the extractor-stem, and whereby the extractor may be projected rearwardly by the spring g.

I am aware that lit is not new in extractor or ejector mechanisms to employ, in combination with the stem of an ejector, a' catch or latch movable angularly to engage a catchnotch therein and aV lever jointedto the latch and arranged to have its swinging movement imparted thereto by contact against a xture or immovable part of the frame of the arm,`hut in such device it appears to have been deemed -necessary to coustructthe .latch and its lever separately and to so arrange or organizethe partsthat the lever has a direct- Y, abutment portion h of the device D, which performs the double duty, first, of throwing the ejector rearwardly when the gun is opened and the catch is positively released', and, secondly, of forcing the device D into the posi- "tion to have its catch 12 engage the catchnotch of 'the ejector when the gun is closed.

The contact-screw q may by being moved inwardlyor outwardly slightly in the threaded socket p therefor have such a location rela-s/ f" tively to' the device D as to operate the latter for the release of the ejector at any desired stage in the opening movement of the'gu.

Having'thus described my invention, what I'claim, and desire to'secure by Letters. Patent, is-- 1. In a breakdown gun, in combination, the gun-frame having at a' forward part thereof an abutment as resist-ant, the barrel having' in its bottom lug the longitudinal bore open at the front and rear ends of said lugand having the transverse aperturej 'leading to said bore, the ejector having its stein provided with acatch-notch, the device, D, comprising the bar or lever member l0 having its forward end pivotally supported by the bottom lng, having at its rear end therigid upward catch extension 12, projecting within said aperturej, havingrat a forward portion thereof the upwardlyextending portion h constructed with the forward member 13, the end of which is adjacent said resistant or abutnient of the frame, and the spring g located in the forward part of said bottom-lug here and operating u pon both the ejector-stem and the said portion h of the single device D, substantially as described. A

/ 2. In a breakdown gun, in combination, the gun-frame having at a forward part thereof the screw-threaded socket p and the screwplug g adj ustably engaged therein, the barrel hinged to the frame andhaving in its bottom I thereof the Aupwardly extending kportion 7i constructed with Vthe forwvrdf member 13,

over the hinge-point the end of which member is adjacent the end of said screw-plug q, and the spring g located in the forward partof said bottom-lug bore and operating end- Wise against both the ejector-stem, and the said portion` h of the said single de rice D, substantially as described and shown.

Signed by me at Ghicopee Falle, Massachusetts, this 21st day of August', 1900.
