Specification forming part of Letters Patent dated February 25, 1836.

To all whom it may concern.

Be it known that I, SAMUEL COLT, of Hartford, in the county of Hartford'and State of Connecticut, have invented a new and useful Improvement in Fire-Arms; and I hereby declare that the following, with the accompanyingflrawings, is a full and exact description of the construction and operation of the said improvements as invented by me.

Division 1 of the drawings represents a pistol. Division 2 represents Division 1 in four sections, as 1, 2, 3, and 4. Division 3 represents all the parts in Section 1 of Division 2. Division 4 represents all the parts of Section 2 of Division 2. Division 5 represents the mechanical combination of the entireinstrument.

Figurelot Division 3 represents the hammer which discharges the percussion-caps. It acts upon a fulcrum at a. b is apin projecting from the hammer, which serves to operate the key that locks the .cylinder when its respective chambers are brought directly opposite the barrel. 0 represents the hole which receives the lower arm of the lifter that tprns the cyl-' inder. V a. represents the part of the hammer where the mainspring acts upon it. cis aprojection by which the hammer is drawn back.

Fig. 2 is the mainspring.

Fig. 3 is the key that holds the cylinder in its place by the arm a when each chamber is brought opposite the barrel. b is a spring, which is attached to the part c, which has a lateral motion to the right by means of a hinge at d, and serves to allow the pin b in Fig. 1 to pass it. The fulcrum of the key is at e. f is the fulcrum-pin. g is the spring which forces the key into the wards of the cylinder.

Fig. 4 is the lifter or hand,with a spring on the left side to allow it to move laterally to the left when acted'on a byeach tooth of the ratchet. At b is a join t, which-connects it with the pin 0, which acts in the hole e in Fig. 1.

' Fig. 5 is the connecting-rod. The end it serves as a catch to the hammer when the lock is set, and when the hammer is pulled back the rod moves forward horizontally in consequence of the ham'mers coming in contact with it, and the end b operates upon the trigger, Fig. 6, at the catch a and throws down the end b, by which means the claw c hooks into the end b of Fig.5, and is held in its place by the spring, Fig. 7, acting upon it at the pin 01.

with the-arbor.

Fig. 8 is the pin which holds in their places the spring,'Fig. 7, at a and the connecting-rod,

Fig. 5, at c. Fig. 6 moves on the pin cat]: s

Fig. 9 is a spring, which holds the rod, Fig. 5, toward the hammer, that the connecting-rod may catch in a notch at the bottom of the hammer to hold it when set.

Division 4 is a dissection of Section 2. Fig. 1 is the arbor on which the cylinder revolves. a a are the hearings on which the cylinder rests. b is the slot through which a key enters to connect Section 4 with it. The part0 passes through the shackle, Fig.2, which is keyed to the cylinder, Section3, Fig.1, at the groove (1 by means of the tongue or projections A on the shackle. e is the part which receives the nut, Fig. 3, when it is connected with the shackle, Fig. 4, as seen at a, Section 2 in Division 2.

Fig. 5 is the ratchet, which is placed in the middle of the shield at a, and receives the shackle, to which it is connected by the tongue or projection b. The arbor is prevented from turning in the shield by means of a pin or key in the shield,which enters the grooved on the arbor.

Fig. 2, Section 3 of Division 2, represents the fore part of the cylinder. The holesu a, &c., represent the ends of thechambersfor the charges. b is the hole through which the arher (on which the cylinder revolves) passes.

C C, &c., represent the wards to receive the end a of the key, Fig. 3, Division 3, to prevent the cylinder from turning when a charge is brought opposite the barrel.

b b, &c., Fig. 1, represent the tubes on which are placed the percussion-caps.

as in Division 1, prevent the communication of fire or smoke from one cap to the-other.

In Division 2, Section 4, a represents the hole through which the arbor' passes, and b a mortise for'the key 0 to connect this section At d the ball enters the barrel from the chamber. At 0 the barrel is lasteued to the plate. At f is a groove in the plate to receive the end a of the lock-plate of Section 1, which serves to steady it. y represents the bayonet hung on a pin at h, i being a catch .to hold it in its place whenit is thrown out. In Division 5 the hammer is hung at the fulcrum a. The key which holds the cylinder G C, &c., are I partitions which, when embracedin theshield,

is hung at the fulcrum 'b'. The lift er that when connected with the shackle. ff is the middle and forward part of the shackle on which the ratchet is placed. gis the arbor on which .the cylinder revolves. The endh is the nut that holds the pin in its place when in the shield. i. i represent the forward end of the arbor which passes througli the plate and the rojection on the lower part .of the barrel, and by a key at j it is secured to the barrel.. k represents the fulcrum of the trigger. l is the spring which forces the connecting-rodagainst the end of the hammer. m is the spring which forces the key that holds the cylinder. '0 is the mainspring. By drawing back the hammer theflpin 1 operates upon the after end of the key (that locks the cylinder) and rises. Gonsequcntly the other end, 1', is drawn from the cylinder, and the arm d of the lifter commences to act on a tooth, a, on the left side of the ratchet, which, being connected to the cylinder by means of the shackle, turns it until the next chamber is brought opposite to the bar- When thepiu p is relieved fromthe key 1 rel. by passingover its ,npper end, t, the pin allows the end r of the'key to be forced by means I of the spring m into the succeeding ward of,

the cylinder. At the same time, by the action of the lower end of the hammer u upon the connecting-rod at c, it produces a forward horizontal motion of the rod, when the end 10 is brought in contact with the upper projection of the trigger and forces it down to a proper position for the finger, when a claw at wof the trigger hooks into the connecting-rod, which holds the hammer when drawn back or set by means of the end a entering the lower catch, 3 on the hammer. To discharge the pistol,

by pulling the trigger the connecting-rod is drawrs from the catch of the hammer,when the mainspring forces the hammer forward, theupper end of which strikes the percussioncap, during which the lifter, by means of lateral mot-ion to the left, falls below a succeeding tooth on the ratchet, when, by means of the lateral motion of the after end 9 of the key I which holds the cylinder, the pin 12 of the ham mer is permitted to fall below it again. By

repetitions of the same motion of the hammer situation of the mainspring and trigger; and,

flourthly, in the construction of the lock-plate lad guards that hold the stock.

Fig. 1 represents the maiuspring. Fig. 2

is the stirrup to connect the mainspring with the hammer. Fig. 3 is the hammer. Fig. 4 is the lever for setting the lock. Fig. 5 is the discharging-trigger. Fig. 6 is the adopter. Fig. 7 is the spiral spring to draw back the adopter. Fig. 8 represents all the parts combined.

To set the lock, the fulcrum of the lever being at a, by drawing down on the end b the and c operates upon the end d of the hammer,

whose fulcrum, being at e, throws back its end f, when the trigger at 9 whose fulcrum is at h) operates upon the catc es of the hammer at .i to hold the look when set. the end f of the hammer is removed from the adopter(whose bearings are at jj)itis drawn back by means of the coiled spring it until its end 1 is drawn. back sufficient to allow the cylinder to turn, which is effected as described in the pistol. After the finger is relieved from the lever (when'the lock is set) a small spring draws it back-toits former place to make room for the end :1 of the hammer, so that its force may not be impaired. By pulling the trigger from the catch of the hammer the mainspring (which is'connected to the hammer by the stirrup o) forces its end f forward against the end m of the adopter,the end l of which is brought in contact with the percussion-cap placed upon the tube a, which discharges 'the load. To load, it is only requisite to draw the key j,

which will liberate Section 4. Then by draw-' ing the key that locks the cylinder (which may be effected by drawing back the hammer) the cylinder may be taken from the arbor.

Amongthe many advantages in the use .of these guns, independent of the number of charges they contain, are, first, the facility in loading them; secondly, the outward security against dampness; thirdly, security of the lock.

against the smoke of the powder; fourthly, the use of the partitions between the caps, which prevent fire communicating from the exploding cap to the adjoining ones; flfthly, by the hammers striking the cap at the end of the cylinder no jar is occasioned, deviating from the line of sight; sixthly, the weight and location of the cylinder, which give steadiness to the hand; seveuthly, the great rapidity in the succession of discharges, which is effected merely .by drawing back the hammer and pulb ing the trigger.

The advantages not applicable to the pistol are the use of the adopter and lever.
