UNITE i; TATES ATENT IMPROVEMENT IN REPEATING FIRE-ARMS.

Specification forming part of Letters Patent No. 9,70] dated May 3, 1853.

To all whom 'it may concern Be it known that I, CHARLES N. TYLER, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Repeating Fire-Arms; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specilication, in which- Figure l is a side view of a pistol constructed according to my improvements, the parts being in their position after discharging. Fig. 2 is a similar view having one side of the stock removed to show the lock, and the charger shown in section. Fig. 3 is a section through the center, showing the position of the parts when the pistol is cocked or ready for discharging. Fig. 4 is a transverse section of breech and lock. Fig. 5 is a projection on a plane of the grooved cylinder at the back of the rotating breech. Fig. 6 is a view of the charger with its cap removed. Fig. 7 'is a side view of the cap of the charger. Fig. 8 represents a view of the iinger-rod by which the cartridge is transferred from the charger into the breech.

Similar letters of reference indicate corresponding parts in each of the several figures.

The principal object of these 'improvements is to bring the whole of the lock, including the hammer or driver, but excepting the trigger, into a space sufficiently small to be contained within the stock, and thus offering no obstruction to the sight, and without increasing its size, so as to make it cumbrous or inconvenient, and at thesame time to produce an arm as sure in its operation and as free from liability to accidental discharge as any in use.

The rst improvement relates to certain means through which the trigger acts upon the hammer or driver for the purpose of cocking and discharging, whereby ,the piece is cocked by drawing back the trigger, and afterward may be uncocked by simply moving the trigger forward.

The second improvement consists in a sprin gstop, which is acted upon-by a small button protruding from the stock at a convenient point to be pressed upon by the thumb or iinger, for the purpose of preventing the possibility of overdrawing the trigger and acci-- dentally discharging the piece in cooking.

The third improvement consists in a charger attached to the barrel in front of the breech,

and which may contain thirty cartridges, more f or less, that may be transferred, one at a time, into the chamber y of the breech by simply pulling a rod with one inger, while with another the breech is rotated and the hammer cocked and tipped andthe charge fired.

To enable those skilled in the art to make and to use my invention, I will proceed to describe fully its construction and operation.

The pistol Shown in the drawings is 'for cartridges which are exploded by pricking, but the improvements are equally applicable when the chambers are loaded with loose powder to be exploded by caps.

The stock is made with the middle part of metal, as being more suitable to admit of a larger Space within, its front end terminating in a disk, A, of corresponding diameter with the rotating chambered breech B. The barrel is Asecured to the breech by a steel Strap, C, screwed to the latter by Screws above and below. The breech lits closely between the front of the strap C and the disk A, having a jour nal, a, in front tting a bearing in the strap, and another, b, at the back fitting a bearing in the disk A. The breech has six chambers and is made solid, and at the back of the jourl nal b, forming one piece with the breech, there is a small cylinder, D, having six spiral grooves, c c, at equal distances apart and parallel with each other, being of equal depth along their whole length, except that at each end there is a slight inclination toward the axis. The number of these grooves corresponds always with the number of chambers.

The spiral grooves are connected with each other by means of grooves d el, which are parallel with the axis of. the cylinder, the latter grooves, d, being rather deeper than the spiral groove c at their back ends, but inclining upward almost to the periphery of the cylinder at their front ends, forming a step, j, at the point of connection with the front end of each spiral groove.

E is the driver, which is a Square steel bar sliding in guides, which keep it in a line with the barrel. It is driven forward by a spring, F, acting on its back end 4when not drawn back by the trigger, and passes through an opening, c, in the disk A, being furnished at its front end with a needle to enter the ventf at the back of the uppermost chamber, or that in line with the barrel. There is a recess, g, in the driver, in which a spring', 71., is secured, carrying at its front end a stud, t', which works in the grooves of the cylinder D. The tendency of the spring is to force the stud to the bottom of the groove.

The movement ofthe driver and the length of the cylinder bear such relation to each other that the stud i passes, and when the breech is stationary with a chamber in line with the barrel the uppermost of the straight grooves d is always in line with the driver. When the driver is drawn back to cock the piece, the stud i', being prevented'by the step j from entering the straight groove, enters the spiral groove c connecting with it, and in moving` along it turns the cylinder and breech the required distance, bringing the next straight groove in line with the driver. On the return of the driver in firing, the stud passes along' the straight groove, and therefore does not move the breech.

T is the trigger, which works on a pivot, 7c, and acts upon the driver through a toothed segment at its upper end, operating on another toothed segment, G, turning on a pivot, Z, and carrying a tongue, m, whose point acts upon a smalljack, a, hanging on a pivot, o, in a slot within the driver. The upper or back part of the jack a catches under a small pin, p, placed across the slot in the driver, and causes it to be held-stationary when the tongue m presses against its front or lower end. A spring, q, is also applied to it for the purpose of holding it in a position for the tongue to act upon it 5 but this spring will yield and allow it to move when it is necessary for the tongue to pass the jack after ring previous to recocking. The hammer is drawn back or cocked by drawing back the trigger and ,pressing the tongue against the jack a, the cocking being caused by the point ofthe tongue entering into a small notch, r, near the point of the jack, and thus forming a direct line bearing between the pivot l in the segment and the pin p in the driver, which balance may be thrown off bythe sli ghtest movement of the trigger either way, consequently a discharge or an uncocking of the piece. The discharge is caused by the point of the tongue leaving the notch r and passing the point of the jack. The driver is then left free to be driven forward bythe spring' F.

The stop s, by which the cooking is insured, is shown best in Fig. 4L, and is also shown in section in Fig. 3, where its operation will be best seen. It consists, simply, of a small flat piece of steel att-ached to a spring, t, whose tendency is to throw it out of operation or away from the driver toward the left-hand side of the stock, which is to the right hand of Fig. 4. .The stud or button S, by which it is thrown in operation, protrudes slightly through the side of the stock, and is always, except when pressure is applied externally, forced outward by a spring, u, inside. (See Fig. et.) Vhen the stud S is pushed inward the stop s is thrown under the driver, where it rests against one of the guides t of the driver or against a suitable rest. The driver moves back just at the moment the p oint of the tongue m falls into the notch r near the point of thejack. The point of the jack, which hangs slightly below the driver, comes in contact with the stop s, and is prevented moving' farther back, stopping the driver. The pointol'the tongue m cannot clear `the point of the jack until the stop s is allowed to move away by removing the pressure from the outside of the stud, and thus letting' the spring tthrow it aside, when by the farther drawing back of the trigger the poi-nt of the tongue is made to cleai' the jack. After the discharge, the trigger, being left free, allows the tongue m to be thrown forward ready for the next discharge by a spring, 10, acting upon the stud fr on the side of the segment Gr, which also moves the trigger forward. rlhe point of the jack is allowed to move forward for the point of the tongue to pass in advance of it by the spring g.

The breech is held rm in its place during the discharge by a stop-pin, y, attached to the trigger, which passes through a hole in the disk A and enters the vent ofthe lower chamber. The piece may be uncooked without discharging by moving' the trigger forward, which withdraws the point of the tongue on from the notch r in the jack, and if the trigger is only allowed to move gradually the driver may be so slowly brought forward as to causeno danger of explosion.

rlhe firing may be repeated rapidly without cooking, if desired, by simply pulling the trigger the whole distance at once.

When caps are used, instead of pcrforating the cartridge, the only difference in the construction will be to have suitable recesses for the nipples at the back of the breech and to m'ake the point of the driver or hammer of suitable form.'

The magazine is externally in the form of a cylinder of greater diameter than length, and has asnag, a, projeetingi-rom one side, which (its into a notch between a snag, b, on the under side ofthe barrel and the frame C, into which the barrel is screwed. When the snag a on the charger is inserted into he said notch it is secured there by means of a key, e, which enters grooves made in the adjacent sides ot' the snag on the barrel and that on the charger'. By this means the charger is secured to the barrel in the position seen in Figs. l and 2.

The magazine is composed mainly of two parts-the body F, which has a central cylindrical chamber, N, to contain an axle and spiral spring', g1", coiled around it, and a spiral chamber, H, Fig. 6, that will contain thirty cartridges, more or less, and a cap, I, to cover the chamber H and protect the cartridges from damp or ignition. The spiral chamber commences at the outer periphery of the case of the chamber H, Fig. 6, at j, and, taking about a turn and a half, terminates at H, where there is an aperture, K, for the discharge of the cartridge Z2 through aperture X of the frame C.

The spiral chamber His fitted with a driver or piston, a2, which traverses it from end to end. The driver is carried by an arm, p2, to which it is connected at its outer end, and which passes through a mortise in the outer end of a central axis, m2, which turns in suitable bearings within the chamber N. As the driver 'n2traverses the spiral chamber H its distance from the central axis m2 is continually varying', and to provide for this variation the arm p2 by which it is carried slides endwise back and forth through the mortise in the axis m2, so as to make its acting radius correspond to that of any part of the groove H in which the driver a2 may at the time happen to be.

The use of the driver is to press the cartridges continually toward that end of the chamber H at which they are discharged, and in order that it may thus act a spiral spring, g2, is coiled around the axis m2, which constantly tends to turn it in the direction indicated by the arrow, and with it the arm p2, which keeps the driver pressed against the cartridges Z2, as seen -in Fig. G, in order that as fast as a cartridge is removed from the front end, H, of the groove H its place is supplied by the driver a2 pushing the whole row forward, so that the foremost of them will take the place of that which was last discharged, to be discharged next.

The cartridges Z2 are discharged one at a time by means of a piston or ramrod, r2, which slides within the hollow standard S2, that projects froln the cap J of the magazine parallel to the barrel Z, and in a line with the lowermost chamber of the breech, the opening within the standard S2 extending through the cap J and the body F. This piston has two arms, a2 u2, projecting through `a slot, 1:2, in the side of the standard S2, and the outer extremity of each arm is fitted with an eye which has a screw cut in it, into which the rod W is litted, as represented in the drawings.

The rod NV enters from these arms through the magazine and terminates in an eye, M, in a convenient position for the first finger of the hand to reach and pull it back, while the middle finger can reach and operate the cockinglever T. The rod XV is, in this instance, arranged on the left sideof the pistol, and is, therefore, adapted to a left-handed person; but the spiral chamber of the magazine can easily be made to diverge from the'eenter in the opposite direction, and the rodW be placed on the right side of the pistol, to adapt it to a right-handed person.

A spring, U, is attached to the cap J by one end, and at the other bears against the inside of the arm a2, tending continually to press the piston r2 toward the outer end of the standard S2. The cartridges Z2 are made in the usual manner and ofthe proper sizeto fit the chamber Hin the breech B. The width of the spiral chamber is such that the cartridge will pass freely along it, and the cartridges are packed in closely together, as represented. When a chamber of the breech is to be loaded, the operator has simply to pull the rod W by its ring M with his linger, when the piston r2 will press against the outer end of a cartridge, Z2, in the chamber and force the same through the opening k into the lower chamber of the breech, the piston being of such a length as to force the cartridge home, and thus, in addition to its duty of transferring the cartridge from the magazine into the breech, it acts also as a ramrod. As soon as a cartridge has thus been loaded into the breech the operator withdraws his finger from the eye M of the rod W, which is instantly drawn back, together with the piston r2, by the spring U, and ready to transfer another cartridge into the breech upon the latter being turned so as to bring one of its empty chambers opposite the charginghole X, and to carry the loaded chamber opposite the barrel Z, to be iired by pulling the trigger T. The driver n2 meanwhile under the pressure of the 'spring g2 forces the cartridges along the chamber, so as to bring another in front of the piston r2, ready to be transferred into the breech.

By this arrangement the lever T can be pulled by the middle finger of the operator alternately with the pulling of the rod W by his rst finger, and thus the operation of loading and discharging will go on regularly and alternately until all the cartridges of the magazine are fired one at a time.

lt is obvious that the construction of the magazine, the arrangement of its details, and the manner of attaching it to this or other tire-arms (for it is adapted to any kind ot' turning or reciprocating breech tire-arms) may be modified to an almost unlimited extent without any departure from the principle developed in the construction and arrangement herein particularly represented and described.

lv have herein described the magazine as applied to a rotating or turning breech; but it is applicable, and I intend to apply it, to firearms of all descriptions that are loaded at the breech. This part of 1n y improvements, therefore, as well as several ofthe other parts, may, with great advantage, be applied without the rest to the improvement of different kinds of tire-arms now known.

I am aware that a machine or charger is described in the patent for a'shoe-pegging machine granted to John Robinson, October 31, 1848, but I make no claim to anything in it.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. I claim arranging the cock in such manner that it may be raised and will stand up without being held by a scar or catch, and may then be gradually lowered again without tripping to fire the charge, or may be tripped to fire the charge, at the option of the operator7 Whether the devices employed be such es are herein particularly described or the equivalent thereof for producting the same result.

2. The movable stop s, operated upon by av stud or button protruding through to the outside of the stock, in combination with 2L fixed rest, o, und the jack n, substantially as described7 for the purpose of preventing the jack being thrownffnr enough back to clear the tongue through which the trigger acts upon it, whereby the escupe of the driver or hainmer is rendered impossible while the stop is in operation.
