To all whom it may concern Be it known that I, EMIL F. FLUES, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Im )rovements in Automatie"Com-' pensuting olts for 'Firearms of theB reakdown Type, of which the followingis a specification.
My nnprovement relates to firearms such as shot guns and rifles of the type known as break-down, that is, they may betiiken apart for convenience in transporting, etc.; and the object of my improvement is to provide means for autoniatlcally taking up thewear in the jomt occasioned by the firing of' the gun and by the breaking of thjsame.
a fragmentary horizontal sectional view taken in line 3-3 Fig. 1, looking'jin thedirection of'the arrow; Fig.4 is afview; similar to Fig.1 but withth'e' barrel and the compensatingbolt removed; andFig. 5 is a perspective view of the compensating bolt per 80.
1 re resents the frame of the gum? represents the barrel, and 3 represents'the lug all of which may be of any suitable we known cdnsti'ii'ctlon, s'uclr'as' illustrated d the drawing. 4 represents the well known ball and socket joint which is rovided between the frame and barrel of t e gun so as to permit of the breaking down of the same, though for the purpose of the present invention this 'oint may be by any well known and suite le construction such as a bin pin. It has been found that considerab e wear occurs in this joint by reason of the firing of the un and also from the breaking down of t 1e same, and various means of adjustment have heretofore been attem ted for compensating for this wear. But t ese means have always been hand adjustments and have prove more or less ineflicient when in the hands of any but a skilled mechanic. The present invention embodies means for automatically compensating for this wear which means will now be described.
The lug Set the barrel of the gun, i. e. that portion, flange, or rib, of the barrel which fitsinto a suitable socket or slot in the frame, is apertured as at 5, for the passage throu h it of the adjusting bolt or wedge 6. Iheadjusting bolt or wedge (5 comprises a body portion 7 having a spring- 'containing hole drilled in its top side and in which hole is seated a spring 8. Two side flanges 9 are secured to the sldes of the body portion, or preferably formed intogrally therewith, each of said flanges 9 being formed with curvilinear front and rear sides 10, and with downwardly extending portions 11 which contact with opposite sides of the lug of the bal'rel when the bolt is in place, and guide the bolt in its movements up and down in the lug. To secure the bolt in place in the aperture of the lug, a set screw 12 is screwed into the In after the bolt is in place and effectually 100 (s the latter in the lug.
The frame 1 of the gun is provided with seats 13 on opposite sides of the slot into which the'lug of'the; barrel is seated, and theseseatsjare formed with curvilinear front sides,-and ar'e"so located that when the'barreland frame are assembled, the 'side flanges 9 of the compensating bolt or wedge will fit down intothem as shown in Figs.
The operation of the above mechanism is as follows: Thespring 8 tends constantly to force the bolt or we go 6 down and the flanges 9 into contact with the curvilinear front side of the respective seat 13 and tends to wedge the frame forward and the lug rearward. It is obvious, therefore, that any wear in the joint 4 will be immediately and automatically taken up or compensated for by the action of the bolt (3.
While it is not absolutely necessary that the faces of the flanges 9 and seats 13 be curvilinear, I find it most desirable that these faces be made with arcuate faces made concentric with the ball of the ball and socket 'oint.
Whi e I have described what I deem to be the best form in which to embody my invention, it is obvious that the exact details as described may be departed from in wnward mo'veiiient (if the" bolt brings" the 'ctiivilinear front face 10 of each of the various partiixulars'f without departing from the spirit of my invention, and I do not limit myself to anything less than the whole of my invention as defined b'y the prior'art'.
And nqiv having fully described my invention, what I claim 'anddesire to secure by Letters Patent is:
1. A compensating 'bolt'for firearms comprising a body portion and flanged portions rigidly secured to opposite sides of said body-portion, one,of saidportions being provided with a spring-seat.
.2. A com ensating bolt for=firearms comprising a odyg portion, and curvilinear flanged portionsrlgidly secured to op osite sides of said body portion, one ofsal portions being provided with a spring-seat.
3. A compensating bolt forfirearms having aspring-containing cavity formed in its top, guldin flanges on its bottom, and a air of forwardIy projecting flanges form on its sides. 1
4. In a firearm, the combination with the barrel, frame, and connecting lug thereof, of a compensating wedge mounted in said lug and automatically operable to compensate for any wear between the barrel and frame.
5. In a firearm of thebreak-down type, the combination with the barrel and frame thereof and the means for hinging the same together, of means for automatically compensating for wear in such hinge and constantly tendin to force said frame and barrel into comp ete en agement, whereby the breech of'the barre is driven against the face of the frame. a
6. In a firearm, the combinationwithrthe barrel, lug, and frame ,thereof, of a compensatin be t for automaticalliy, taking up any wear tween the barrel an H the frame, said boltbeing mounted inisaid lug, and means; for securely fastenin said be t in said In and allowing said bo t a limited amount 0 movement. a
7. Ina firearm, thecombination with the depict this fan; elatahuid for BEST AVAILABLE CGPY barrel and thefla'me thereof, of the lug for connectin said barrel and frame and pro- Yided witfi an aperture therethrough, a compensating bolt seated loosely in said aperture, means for securing said bolt in said apertur'e', and'a spring seated in said bolt and bearing ainst said barrel so as to cause said barre and frame to move into complete engagement.
8. In a firearm, the combination of a frame rovided with a pair of oppositelydis ose seats, a barrel, a lug on said barrel an formed with an aperture therethrough. a bolt seated in said aperture, and means for causin .said bolt to bear constantly against. one si e of said aperture and against one side of each of said seats.
9..In a firearm, the combination of a frame provided with a )air of oppositely disposed seats each of which has a curved Side, a. barrel, a lug on said barrel and provided with an aperture therein, a bolt seated in said aperture and having a pair of oppositely disposed curvilinear flanges, and means for forcing the curved faces of said flanges into contact with the curved sides of said seats.
10. In a firearm, the combination of a frame provided with a pair of curved shoulders, a barrel hingedly connected with said frame, and a compensating bolt having a pair of curved shoulders adapted to aniomatically contact with the first said shoulders and force said frame and barrel into complete engagement, the construction and arran ement being such that said curved shoul ers are all arcuate and have a common normal center, and that one of said airs of shoulders is movable in a straight ine with relation to the other of said pairs of shoulders.
