ANDREW FYRBERG, OF HOPKINTON, MASSACHUSETTS.
FIREARM.
To all whom it may concern:
Be it known that 1, ANDREW FYRBERG, a citizen of the United States, residing at Hopkinton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Firearm, of which the following is a specification.
This invention relates to a firearm and while capable of general use is particularly adapted for revolvers.
The principal objects of the invention are to provide an improved means for swinging the cylinder out from the frame; to provide an improved construction of manually operated extractor; and to provide an improved construction of safety and rebounding device connected with the trigger and operated directly thereby so that the hammer will be positively prevented from being fired when the trigger is in any intermediate position and so arranged that this safety arrangement will let go of the hammer when the trigger is pulled back to the limit of its stroke.
Further objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accon1pany ing drawings, in which- Figure l is a side elevation of a revolver showing a practicable form of the invention 7 applied thereto; Fig. 2 is a side elevation of certain parts of the same removed from the frame; Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1; Fig. 4 is a plan of a portion of the frame showing the cylinder swung outwardly and the extractor in operative position; Fig. 5 is a horizontal sectional view of the same showing the parts in the same position; and Fig. 6 is a sectional view on the line 6- 6 of Fig. 4 with the cylinder removed.
The revolver is shown as provided with aframe 10, barrel 11, cylinder 12, hammer 13, trigger 14, hammer-spring 15, and triggerspring 16, all of which can be arranged in any well-known way, but having certain features constituting a part of this invention. The cylinder is mounted on a block 17 which swings on a vertical pivot 18 that is supported by a link 19 which in turn swings on a vertical pivot 20 mounted on the frame. The cylinder has a forward extension 21 which engages the edge22 of the frame as the cylinder swings out to limit its outward motion. This extension and the link under it fill a side opening in the frame. It will Specification of Letters Patent.
Application fi1ed February 1, 1909.

Serial No. 475,410.
be seen that the cylinder has a compound motion and that the first part of its motion is almost entirely on the pivot 18 as a center when that pivot is in its original position in the frame, but that as it swings outwardly this pivot itself swings on the pivot 20, and consequently the cylinder is released from the frame in a very rapid manner and can be brought out to the side very quickly and with very little trouble. In the cylinder is an extractor 23 as usual provided with a rod 24 extending forwardly and having a head 25 thereon by which the extractor can be operated by hand. hen these parts are closed up into the frame, the edge of the head 25 engages in a notch 26 inthe barrel and the extractor is firmly held in position. On the inner end of the extractor is a pin 27 adapted to engage a recess 28 in a springpressed catch 29 supported by the frame. This constitutes a positive holding means for the extractor and cylinder.
The trigger is provided with a pawl 30 for operating. the cylinder as is well understood. It is also provided with a pawl 31 for operating the hammer, this pawl being pivoted on the back of the trigger. The hammer has a forwardly extending projection 32 at the bottom which the pawl 31 is adapted to engage. The other side of the notch usually provided above this projection is bounded by a spring-pressed member 33 pivoted on the hammer and normally projected forward therefrom by a spring 3 1. In the end this has a notch 35. Pivoted on the back of the trigger is a reciprocating bar 36 constituting a rebounding and safety device. It is shown as provided with two projections 37 fitting in notches 38 in the hammer when the safety is moved to its uppermost position when drawn back by the hammer. This permits the arm to be fired. In any other position, however, this projection 37 would engage the hammer and absolutely prevent the discharge of the firearm.
On the member or safety 36 is located a fixed projection 39 adapted to engage in the notch 35. It will be seen that when the trig ger is in any intermediate position the bar 36 is also in an intermediate position and the projection 39 prevents the hammer from descending. When the trigger is drawn clear back the projection 39 slips ofi the edge of the notch 35 and permits the hammer to be operated in the usual way, the safety then being in its uppermost position for permitting the discharge of the arm. It will be seen that the safety, which on account of the shape of the projection 37 constitutes a rebounding device, is operated solely by the trigger and trigger spring, and that no other rebounding device is required, and that in addition to the prevention of accidental firing due to the presence of the safety 36 the connection of the safety with the member. 38 affords further protection against accident, and thus there is absolutely no danger of accidental discharge even with the roughest kind of handling.
It will be seen that the firing pin 40 is shown as located directly on the hammer and integral therewith, and that the safety is bifurcated and receives the firing pin between its bifurcations.
IVhile I have illustrated and described a preferred embodiment of the invention I am aware that many modifications may be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction shown, but
