Application filed April 29, 1908. Serial No. 429,907.

To all whom tt may concern.

Be it known that I, ANDREW Frnnnno, a citizen of theA United States, residing at Hoplriuton, in the county f Middlesex and State of Massachusetts, have invented a new and useful Firearm7 of which the following is a specification. This invention relates to a firearm.

The principal objects thereofare to provide an improved'safety for effectively preventing the firing-pin from being actuated to fire the' arm whenever the hammer is accidentally vor otherwise caused to swing down away from any position except that in which it' is fully cocked or ready for repeated firing; to provide .for simultaneousiy moving ingA drawings which Ashow certain forms in which the invention may be carried out, and

in which- Figure 1 is a side elevation of a revolver with one form' ofvthe invention applied thereto, parts heilig' shown in section, and in safe position; Fig. 2 is a similar view showing howthe parts appear when the hammer iscoclied; Fig. 3 is a similar view showing the position of theparts when the arm is fired; and Fig. 4 is a View similar to Fig.4 3

showing a modification.-

- It -is to he understood that while the invention is illustratedras applied to a revolver,

it can be applied to many other styles of tirearms. In the first three figures of the drawings, the invention is illustrated -as applied to ,a revolver having a fra-me 10 of ordinary construction provided with a swinging cylinder 1'1, the operation of which will notbe referred to herein as vit constitutes no part of this invention. The frameis provided with a trigger guard 13 of any ordinary *or convenient construction, and the trigger 14 is= mounted' thereon in tlie usual position.

The vtrigger is operated to return it to its' normal position by vi'neans which can conveniently bezlocated in the frame and guard unde'rthecylinder and forward of the trigger so as to secure a' direct" pull on the trigger, and so as to provide for convenient adjustnient from the front of the frame. This is shown as comprising a rod 15 pivotally con neoted with the trigger below the pivot on which the latter swings, and projecting forward into a cylindrical opening 16 in the triggerguard or frame. It is shown as in the former. The guard is provided with, a partition 17 .having a perforationthrough lwhich the iod slides, and the rod is provided with screw-threads andwith an adjustment nut 18 on the end thereof which can bc reached from the outerend of said opening 16. Between the nut and the partition is located a spring 1,9 which obviously tends to pull theutrigger'forward. This is a simple and convenient arrangement, giving a direct pull onthe trigger and permitting adjust- .il

ment in a most convenient and simple manner.-Y It iswso located that it takes up no room which can be used for any other purpose, and does notiadd to the weight ofthe firearm. v

On the trigger is located a projection 21 provided with a pin or. screw 22 by .which a frame 23 is pivotally connected with the trigger so as to he operated positively there` by in both directions'. This fai-ne is prov vided with a pair of longitudinal guides 24 adapted to engage in ways 25 on theframe so that as the trigger swung back and forth the frame will be caused to reciprocate vertically in frontof the' hammer 26. This frame constitutes a safety, and for that puriose the hammer and trigver are )rovided' l. .ab

with ,means whereby when the hanuncr is brought up against the safety from any po-l sition exceptl that in whichit is cooked, it

will be held back from firing position. This Ameans is`shown as comprising aprojection 27 on the safety and a notch 2S on the hammer. Theparts are so proportioned that when the trigger is brought back to a position in which it will first oockxthe hammer and then slip by to allow it to swing down to firing position, the safety will be in its highest position in which the projection'registerswith the notch as shown in Fig. 3. At

this time, of course, the hammer-'can descend and its flat surface 29 will engage the firing pinBO and fire the-arm. hammer isbrought back either. by means of the trigger or by a direct pull onfthe ham# iner, to any positionshort of that ,in which it is cocked, and then allowed to swing back toward, the safety, the safety will not be raised to itsY tiring position, but will he If, however, the

kept below that position by the trigger, so that the surface 29 of the hammer will env gage 'the projection 27 and prevent the discharge of the arm. These features of the invention are substantially the same in all the figures illustrated in the drawines.

lnfthe first three figures an additional safety arrangement is provided which consists in pivoting the tiring-pin itself on the safety. This is done by providing the tiring pin ywith a longitudinal slot 3l and the safety with a pin 32 passing through this slot. A'spring 33 is also provided forassisting in manipulating the tiring pin in an obvious manner. It will vbe readily understood that the lowering of the safety will swing the tiring pin down as indicated in Fig. l, so that it will be entirely out of position for iiring, and thus another means is provided for preventing the discharge ofthe firearm.

In the form of the invention shown in Fig. 4, the last mentioned feature is not employed, as the tiring pin consists of a projection integral with the hammer. In this case the safety is provided with a long slot 36 for the'reception of the ring pin. Otheririse -itworks substantially the same as in the other case. It will be seen that this invention involves `the provision of means whereby the accidental discharge ot the firearm is rendered impossible preferably in two independent ways, and with a mechanism which is exceedingly simple, inexpensive and light; also that even when constructed in the simpler form shown in Fig. 4, the accidental discharge of the arm is perfectly ,inipossible, and that the trigger spring is greatly improved andysimplilied, and has direct and positive control of the safety.

While l. have illustrated and described certain forms in which the invention may 4be embodied, am aware that many modifications may be made theJ-ein 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 in all respects to the details of construction shown, but

What l do claim is l. In a firearm, the combination withthe trame, trigger-guard, and trigger, said trigger guard having an opening extending inwardly from its forward. end, oi a rod pivotaliy connected with said trigger and eX- tendingr forward into said opening, a spring on the rod, an adjustable.y devicel for connecting the end of said spring with the rod, and.

means for holding the opposite end of the U0 spring. v

2. ln a firearm, the combination with a hammer, ot' a safety infront of the hannner, a firing-pin movably supported on the Safety and adapted to slide-longitlulinaliy thereon (35 when'struclc by the hammer, and means for moving the safety into position for permitJ ting tiring at all Ytimes except when the hammer is in fully cocked position.

In a tiren-rm, the combination vwith the frame a trigger and hammer, of a rectilinearly sliding safety located in front of the hammer, said hammer and safety havinga projection and depression adapted to register when the arin is fired, said trigger having means for moving the safety into such position that the depression and projection will be out of registration when' the trigger is in any position except that in which the hammer is fully cocked, and means on the frame independent of the hammer Ytor gniding the safety to move vertically7 and for preventing the safety from swinging toward the hammer.

4t. In a firearm, the combination with the' trame a hammer having a notch therein, of v a reetilinearly sliding safety in front .of the hannner having a projection adapted to fit said notch, means for moving the safety into position with its projection ont of-registration with the notch at fillet-mies except when the hammer is in fully cocked position, Aand means on the frame independent of the hammer for guiding the safety to move vertically and'for preventing the safety Jfrom swinging toward the hammer. 95

G. In a firearm, the combination with a hammer having a notch'therein, of a sliding safety in front of the hammer having a projection adapted to fit said notch, means for moving the safety into positionout of istration with the notch at all times except when the hammer is in fully cocked position, and a tiring pin pivotally nounted on the safety and adapted to slide longitudinally thereon when struck by the hammer.
