ALARM DEVICE FOR SHESEPFOLDS.

SPECIFICATION forming partof Letters Patent No. 648,056, dated April 24, 1900.

Application filed July 14, 1899.

T ctZZ whom it may concern:

Be it known that I, WILLIAM I). REYNOLDS, a citizen of the United States, residing at Mountain Home, in thecounty of Elmore and State of Idaho, have invented a new and useful Alarm Device for Sheepfolds, of which the following is a specification, reference being had to the accompanying drawings, formin g part thereof, wherein the same letters and numerals of reference pointout the same parts in all the figures. 7

My invention relates to means for protecting flocks and herds from the depredations of wild animals, especially where of necessity the flocks or herds are scattered over a considerable expanse of territory away from the immediate vicinity of human dwellings. Such conditions prevail on many of our Western ranches, and the protection of sheep and lambs, for instance, particularly during lambing season, has become a serious problem. At such a time unless rigid preventive measures are adopted wolves and coyotes are very apt to harass the flocks, worrying the sheep and devouring thelambs, causing in many instances a considerable loss. It has been customary to have men armed with shotguns or with other weapons that would prod uce a loud noise make the rounds of certain portions of 0 the ranches at regular intervals, discharging their weapons as they went. This has proved fairly satisfactory in many cases as a means of frightening off the wild animals; 'butlike every other scheme which depends for its suc-' cess upon purely human agency'it is apt to fail at critical times by reason of that agency going astray. The men selected for this duty may be trustworthy and proper persons, and in such case the flocks are fairlysafe; but it frequently happens that drowsiness or a more potent and insidious influence overcomes the watchmen, and the absence of the flashes and reports of the alarm-guns gives the wolves and coyotes an opportunity of which they are not slow to avail themselves.

My invention has for its object to provide mechanisms that when properly set will take the place of the watchmenaoove described. I distribute these mechanisms, which are, in effect, automatic periodically-operating firearms, through the ranges or folds to be pro- Serial No. 723,804. (No model.)

v tected and arrange them so that if properly apparent from the simple statement of their functions. The firing mechanism causes the discharge and works the magazine-feed. The controlling time mechanism at fixed and predetermined intervals releases the firingmechanism. The time mechanism of course requires to be rewound, and the magazine requires recharging at intervals; but by having the work done systematically and making regular rounds at stated intervals the trouble and inconvenience thus involved are reduced to a minimum. Instead of having them riding over beats in the vicinity of the flocks to be protected I have a patrol make the rounds of all the alarm mechanisms once a day or once in two days to inspect them and at the same time rewind and reload them. The mounts are so constructed that the casing may be taken from the support and easily carried by a man on horseback if it is found necessary to repair the mechanism, and apatrol should never go out without carrying one or more extra cases with him.

My invention is fully illustrated in the accompanying drawings, Wherein-.

Figure 1 is aside view of the mechanism of my alarm device, one of the cheek-plates and the gun-barrel being partly broken away. Fig. 2 is a View of the magazine and firing mechanism from the opposite side of that in Fig. 1. Fig. 3 is a plan view of themagazine 5 and tiring mechanism, and Fig. 4 is a longitudinal section through the same and thebarrel looking in the same direction as in Fig. 1. Fig.5 is a perspective viewshowing the mount .ing of the entiredevice and also indicating the manner in which the devices are located ina sheep-field.

Referring to Fig. 1, which shows all the operative parts assembled, the controlling time mechanism will be observed at the left. It is lettered O in its entirety. The firing mechanism is shown in the center of the figure, and the breech of the gun, with the cylinder or magazine, is shown at the right. The time mechanism 0, which I have chosen to use with the present form of alarm, consists, essentially, of a double train of gears, each having its own driving-spring, one train being the time-train proper and the other what I shall hereinafter denominate the firing-train. The time-train consists of arbors 1, 3, 5, 7, 9, 11, and 13, mounted in a framework 0, similar to the framework of astriking-clock. The arbor 1 carries the main driving-gear 0 and the mainspring S. It has a squared end for the reception of a suitable key for winding and is supposed to be connected with the gear; 0 by means of the usual ratchet-wheel and pawl. This is not shown, because it is of the pat-tern used in all clock mechanisms and would only complicate the drawings. The main driving-gear c meshes with a pinion on the arbor 3, the gear 0 of which meshes with a corresponding pinion on the arbor 5, whose gear 0 through the pinion on arbor '7 and its gear 0', drives the scape-wheel c on the arbor 9. The movements of the scape-wheel, and thereby the running of the clock-train, are regulated by an anchor-escapement, which does not show in the drawings, but which is controlled through the balancewheel o mountedon arbor 11, and actuated by the hair-spring 0 The escapement-lever is mounted upon the arbor 13 and carries the verge or tailpiece 0 The firing-train consists of the main gear 0 carried on the arbor 2, which also carries the mainspring S and has a squared shoulder for the reception of a key, together with the ratchet-and -pawl winding connection hereinbefore referred to in connection with the other train, together with the gears 0 c, and c and their pinions mounted upon arbors 4:, 6, and 8, respectively. The arbor 6 in addition to the gear 0 and its pinion carries a cam-disk 60, having one edge slightly flattened and provided with a notch 6i. Pivoted upon a post 10 to freely turn thereon is a three-armed detent 0 one arm being a spring extension 0 A second one 0 rides upon the periphery of the cam-disk 60, while the third arm is bent upwardly almost on a radial line intersecting the arbor 2 and 0011- stitutes a detent or stop for the main gear 0 A spring-arm c issecured to a post 0 and overlies the upturned end of the arm 0 It will be readily u nderstood from the above description that the construction of the timetrains does not diifer greatly from that of a good striking-clock. The operation is very simple. A pin or pins carried upon one of the wheels of the time-train and not shown, because on the other side of the train, serves or serve to release the detent 0 and to permit the gear 0 to revolve, turning the gears 0 c and c with it. The gear 0 is adapted to make one complete revolution while the gear 0 is revolving through an angular-distance shown in the drawings as the distance between centers of the pins of, set into it's periphery. These pins 0 constitute the direct firing means of the firing-train. Alever H is pivotally supported, by means of struts h and it, upon a post 7t and has its end 7L7 extending into position to be engaged, as shown, by the successive pins 0 as the gear 0 revolves in the direction indicated by the arrows. The outer end of the lever H carries a heavy-weighted head h, secured to the lever in any suitable way, as by a set-screw 71 and having a reduced portion h rearwardly beveled, as at 7L2. This hammer-head may be constructed of anyheavy metal, and, in fact, may be a lead casting around an iron core; but the striking part 7t must be of hardened metal in order to stand the wear of repeated blows. The lever H has a certain amount of resilience, by virtue of which it may be stopped after a certain length of stroke without stopping the hammer-head, a quick rebound of the latter being thereby assured.

I shall now describe the gun proper, with its magazine, and then turn to the firing mechanism, which forms the connecting-link between the firing-train and the gun. The firing-train and time-train are not shown elsewhere than in Fig. 1; but the rest of the mechanism is clearly displayed in Figs. 2, 3, and 4. In all of these figures, A is a gunbarrel terminating in a breech-piece A. This breech-piece is preferably made quite bulky and heavy in order by its inertia to absorb the greater part of the energy of recoil, thereby preventing the transmission of sudden and violent strains to the rest of the mechanism. Th'ebarrel and breech-piece are fitted in a frame B, which has an upwardly and forwardly extending member b 'secured to the gun-barrel by bolts b tapped therein. A certain distance to the rear of the breechpiece A the frame B has a second uprising member I), which forms a false breech for the gun. Between this false breech and the breech-piece the ,cylinder A is revolubly mounted by means of the cylinder-bolt A which, as shown in Fig. 4, passes through the false breech b and is tapped or screwed direct-ly into the body of the breech-piece. One object attained by this construction is the transmission of all strains from discharges through the cylinder-bolt to the breech-piece.

B is a firing-pin case ortub e suitably connected to the false breech b, as by screwthreads I), and having its axis coincident with the axis of the gun-barrel and of any chamber in the cylinder which may be turned into position for firing. Within the tube 13 the firing-pin U is fitted, so as to reciprocate within certain limits, these limits being cletermined by a suitable slot in the pin and a limiting-screw 19 in the tube. The firing-pin is kept normally in retracted position by a spiral spring b which encircles the inner reduced end thereof, resting at one end against the shoulder formed on the pin by this reduction and at the other end against the solid end wall of the tube B The gun-barrel, cylinder, frame B, and fi'ring-pin mechanism, as thus described, constitute a separate organized piece of apparatus capable of separation from the rest of the mechanism for packing or for repairs in a manner that will presently appear. It will be observed that I have heretofore referred to the cylinder A under the generic title of a magazine. I have chosen to do this for two reasonsfirst, because the cylinder is in practice of a greater relative diameter than that shown in the drawings, having chambers for a great many cartridges, and, second, because I consider my invention to be generic in its nature, and While an ordinary revolving cylinder is shown it would not require many changes to add a feed-hopper or a slidemagazine to the mechanism here illustrated, and, as will suiiiciently appear from the claims hereto appended, Iconsider such addition, broadly speaking, to be within the scope of my invention.

I shall now proceed to describe the firing mechanism proper. This, like the other portions of the apparatus, is complete in itself to the extent of forming when detached an organized piece of apparatus. It consists, essentially, of a frameworksupportin g a springmotor and firing-cam, together with means operated thereby to turn the cylinder step by step, one step for each operation, so as to bring fresh cartridges successively into line with the gun-barrel and the firing-pin. A curved frame-piece B is secured at its forward end to the gun by means of a pair of uprising ears Z7 which embrace the breechpiece A and are secured thereto and to each other by a through'bolt. This forms a solid connection, it will be observed, with the gunbarrel and its attached part, and the attachment is made more secure by a short screwbolt b which passes up through the framepiece B into the frame B.

At its rear end the frame-piece B, which, it

will, be understood, may be a single curved piece or may consist of a pair of connected straps, is provided with a rectangular extension 1), drilled at 19 as shown best in Fig. 3, for the reception of bolts which serve to secure the timing mechanism in position.

Extending from front to rear of the framepiece B on both sides thereof are cheek-plates B connected together by cross bars I)", through which pass bolts Z2 to secure the cheek-plates to the frame-piece. Journaled between these cheek-plates are two arb'ors cl and d The first carries the firing cam or block D and the pinion d, rigidly fixed thereto, while the second carries the gear-wheel (:1 which intermeshes with the pinion cl and a star-wheel (i outside of the cheek-plate, is a heavy drivingspring 8*, whose outer end is fast upon a pin or post d, attached to' the cheek-plate. The arbor is provided with the usual shoulder s for the reception of a winding-key.

The firing cam or block D is made very heavy, so that with a single revolution when released it will gather sufficient momentum to strike a considerable blow upon the firingpin. The means by which such blow is struck are as follows: Extending inwardly from the periphery of the block D, I form a substantially-radial chamber d within which a block D is fitted to reciprocate. This block is kept normally pressed outward by a helical spring d but it is prevented from being forced entirely out of the chamber by side pins or trunnions 61 (best shown in Fig. 1,) which work in slots 01 and are overlaid by a retainingplate 01*, secured to the block D by screws (1 and having its surface flush with the surface of the block D. The sliding block D is notched at d in a peculiar manner for the reception ofthe beveled face 77, of the hammer h, and normally the block rests against the rear end of the firing-pin, serving as a detent to prevent the rotation of the firingcam D. Pivoted at 11 on the false breech b is a retaining-pawl B one end of which, I), engages with notches e in the cylinder A to normally hold the same against retrogression. A longer arm I) entends rearwardly inside of one of the cheek-plates into position to be engaged by a pin d on the firing-cam D, being normally held up against said pin by a spring b". On the opposite side from the retaining-pawl B and pivoted at d to the cheek-plate B is a pawl-lever D having a pawl end extending over and engaging with the notches a in the periphery ofthe cylinder A The pawl-lever is normallykept with its end pressed against the cylinder by means of a spring at and has its opposite end 01 extending into position to engage the teeth of the star-wheel d as the latter revolves. It should be observed that the notches 0, engaged by the retaining-pawl B and the other notches a engaged by the pawl (1 are formedin reverse relation to each otherthat is to say, the retaining-pawl rests on the upper side of atooth in its notch a while the pawl (1 rests on the upper side in the notch of atooth of the oppositeseries the cylinder being thus held from displacement in either direction when it has been moved so as to bring a chamber into firing position.

Before closing this description of the operative parts and in advance of the explanation of their operation I wish to direct attention to Fig. 5, in which alone the casing and mounting of my apparatus are shown. E in Fig. 5 is a metallic box or casing having a water-tight lid E, preferably secured to it by attachments which permit of looking, as by means of the padlocks shown. The bar- Also secured to the arbor d IIS rel A of the gun mechanism protrudes from one end of the box, and upon the other end I usually paint a serial number in order that each box may be kept track of. The entire box or casing is mounted with its substantial center of gravity in the vertical line through the center of a tripod-plate, the legs of the tripod being firmly secured to the plate and shod with iron or steel points, so that they can be driven wellinto the ground. The size of the casing is somewhat exaggerated in the drawings, the actual dimensions being only those necessary to allow thecasing to receive the apparatus shown in Fig. 1, which in the drawings is full size.

It might reasonably be asked why a gun mechanism and not some flashing detonator is employed for these alarm purposes. There are two reasons. One is that the appearance of the apparatus when mounted on a tripod renders it different from what the wild animals are accustomed to see, and to their instincts it appears the work of human hands. The second reason is that it is not the noise alone which frightens the wild animals, but the belief inspired in their minds that the noise is caused by a firearm in the hands of a human being. It has been found that the nearer the alarm approaches in its sound to the sound of a watchmans gun, which they are accustomed to see inflict damage, the more effective it is.

The complete apparatus (shown in Fig. 5) is placed in position, the clockwork and the firing-spring are wound up, the chambers of the magazine are fully charged, and the box can be locked and left during a period su fficient to permit the discharging of all the cartridgesnvith the full assurance that there will be no loss due to failure of the alarm. It should here be explained that the duration of the time involved between shots is regulated by changing the number of pins in the tripping-wheel of the time mechanism C. It has been stated that a pin (notshown) first lifts the detent 0 and that the cam then retains the detent in its lifted position during a stated interval. In order to regulate the time interval between these operations, it is obviously only necessary to alter the number of pins on the tripping-wheel, and this being a common expedient in striking clock mechanisms is not illustrated. I have found it expedient to cause the hammer h to fall and fire a shot once in fifteen minutes. This requires four cartridges per hour, and for a period of twenty-four hours this requires ninety-six cartridges. It is possible, without exceeding reasonable limits, to make the cylinder A of sufficient size to chamber one hundred cartridges. These may well be specially-prepared small'caliber cartridges having a long shell, so that the diameter of the cylinder should be kept as low as possible. If any greater length of time be contemplated, it is necessary to introduce a different form of magazine, retaining the cylinder principle,

shown in Fig. 1.

but adding a feed which will eject the empty shells from the lowermost chamber and insert a fresh cartridge at each step in the revolution. I do not consider it necessary to show such a magazine, as it is to form the subjectmatter of a later application.

Having thus described the mechanical construotion of my invention, its operation will be .understood. Supposing that the springs S, S, and S have been wound and the parts are all in the position shown in Fig. 1, which is normal, the timing-movement C will operate in the ordinary way, being regulated in its running down by the scape-wheel 0 At a predetermined moment the tripping-pin 011 the proper gear of the time-train will turn the detent 0 upon its center 10 and release the firing-train. Spring S, through the medium of gear 0 will immediately communicate motion to the gear 0 which, it will be re member-ed, carries the pin 0 The particular pin which at the time overlies the trippingend h of the lever H will depress that end until the lever has swung on its post 7& sufficiently to permit the pin to ride over and escape from the end thcreof,the hammer-head being by this operation lifted higher than The gearing c 0, and c is so proportioned that the gear 0 will turn through a distance equal to that between two of the pins while the cam 60 is making one revolution. Thus the firing-train Will 0011- tinue to operate until another pin has taken the place of the one which actuates the lever II. When the pin rides off the end of the lever, the weight of the hammer it causes it to drop with considerable force upon the sliding block D, driving that block down into the chamber (1 against the stress of its spring. The part h of the hammer falls into thenotch (1 also of the block,with its beveled face resting upon the oppositely-beveled face of the notch. The spring S through the medium of gear (1 and pinion cl, strongly tends to produce rotation of the firingcam D in the direction of the arrow shown in Fig. 1; but such rotation is normally prevented by the sliding block D resting against the rear end of the firing-pin. When the sliding block is depressed,however, by the blow of, the hammer, the cam D is free to revolve, and immediately does so, the inclined face 71 on the hammer riding up on the correspondingly-inclined face of the block, and tending by its inertia to keep the block depressed until it is past the firing-pin. As soon as the block D has been carried past the firing-pin its spring d forces it out once more into the positions shown in Figs. 1 and 4E, and consequently at the end of one revolution of the cam D the block D will spring up against the end of the firingpin with all the energy that has been accumulated by the cam D durin g its revolution, the firing pin being thus driven in forcibly against the primer of the cartridge to explode it. After the explosion the parts remain in the position shown, the firing-pin resting upon the exploded shell and continuing to serve as a stop for the sliding block D until the next operation. In order that a fresh cartridge may be brought into position at the next operation, it is necessary that the cylinder be rotated just prior to the actuation of the firingpin, and this is accomplished by the pawllever D and the star-wheel d The proportion of the driving-gear d to the pinion cl and the number of teeth on the star-Iwheel are such that one tooth Will push up to pass the end d of the pawl-lever for each complete revolution of the firing-cam D. Therefore asthe hammer releases the cam D and permits it to revolve pin d will first depress the leverarm 6 of the cylinder-locking pawl, and then as the revolutionproceeds the star-wheel will in turning actuate the pawl-lever D to rotate the cylinder the distance between centers of two chambers. The instant the proper chamber comes into line it Will stop, for that is the instant at which the rotation of the cam D ceases,by reason of the block D springing up against the end of the firing-pin. Thus at the end of every time interval previously determined the tripping-pin on the timingtrain will trip the detent of the firing-train, which will drop the hammer to permit the firing-cam to revolve, in its revolution working the cylinder to bring a fresh cartridge into position and finally to explode the same, this explosion forming an abrupt termination of the whole operation.

By removing the through-bolt Z9 and the other bolts Z2 and Z7 the mechanism will be separated into three distinct and uniform parts, when it may be readily packed or any one part exchanged for a new one.
