SPECFICATION forming part of Letters Patent No. 726,131, datedfAprI 21, 1903. I 4 Application iiledJuly 28,1902. Serial No. 117,378. 'No model.) i

To all whom, t may con/0677;." A

Be it known that I, JOHN S, BARNEs,-a citizen of the United States, residing at Payette, in the county of Canyon and State of Idaho, have invented new'andusefulImprovements in CoyoteAlarms,'offwhichthe following is a specification.' y

My invention relates to coyote-alarms or scarecrows; and the Object of the same is to construct a device of this character which will be automatically operated to explode a cartridge at previously-determined intervals to scare coyotes away from sheep-pens.

The simple and novel construction em-V ployed by nie in carrying out my inventionV is fully described in this specification and claimed, andillustrat'e'din the accompanying drawings, forming a part thereof, in which- Figure 1 is a perspective of a iigure bearing my automaticV device. Fig-2 is a front elevation of the operating mechanism. 3 is a side elevation of the same.I Fig. 4 is a plan View, partly in section.. Fig. 5 is a rear view. Fig. 6-is a detail cross-section of the slotted tube. Fig.` 7 is a detail view of' the operating mechanism. Fig. 7a, Sheet 2, is a detail of the trigger-lever. Fig. 8, Sheet l, is a detail of the brake mechanism.

Like numerals of reference designate like' parts in the different views'ot' the drawings.

The numeral 1 designatesthe figure of a man, which gure is set-in an upright position, with stumps 2 of arms extending horizontally. My automatic detonating device is mounted in the breast of the figure 1,. A metal breast-plate 3is attached to the ligure 1 and has a circular aperturel` therein,within which a cylinder 5 is revolubly mounted. The cylinder' is analogous to the cylinder of a revolver of large -size and has' a number of chambers 6 therein arranged in a circle and constructed to hold blank cartridges. An axle 7 passes through a head-plate 8, supported on feet 9,- and secures the cylinder 5. A

circular series of beveledv teeth 10 are formed ou the inner end of the cylinder 5 and coperate with a pawl 11, carried by a wheel 12,

keyed on a shaft13, journaled in a bracket-V a post 25.

which extends through the slot l5ZL inthe tube 15. This plunger 16 is designed to serve to explode the blank cartridges carried bythe cylinder 5. An aperture 19 is formed in the head 8, through which. cartridges can be inserted into thecylinder 5.

Located adjacent to the rack 18 is a mutilated gear 20, which bears two sets of teeth 21, separated by smooth arcs 22 about a quadrant in length, which teeth are in position to mesh with the rack 18 as the gear 20 is revolved. The gear 2O is carried bya shaft 23, jonrnaledin bracket-arms 24, supported by Two ratchet-wheels 28 and 29 are also keyed on the shaft 23 and each bears two teeth 28a and 29, respectively. The teeth 232L are engaged by one arm 30a of tne lever 30, normally heldin engagement therewith by a spring 31, while the teeth 29a are designed to engage the hooked end 33a of a connectingrod 32, which is pivoted to the pawl-bearing wheel 12. The upper end ofthe rod is mounted in guides 33, which serve to hold it in position. A brake 3i, which engages the wheel 12, is operated by the Vrod 32.

A-spiral spring 35 surrounds the shaft 23 and is arranged to operate said shaft to operatethe plunger 16 to explodethe cartridges in the cylinder 5. The spring 35 is wound by means of a key applied to the squared end 23av of the shaft 23.

The lever 30 normally holds the spring 35 Yfrom running down. ATo intermittently Operate the lever 30 to release the spring 35 at predetermined intervals to operate the plunger 16, a` mechanism is provided which comprises a clock mechanism 36, located'adjacent to the long arm 30b of the lever 30 and bearing a circular disk 37, which is keyed on the hour-hand shaft 3S and bears four pins 39, located at intervals of a quadrant thereon. By means of this arrangement the lever-arm 30n is engaged by the pins 39 every quarter of an hour to operate thev lever 30 to release cylinder 5.

When in use the figure l is set up near a rthe shaft 23 to operate the plunger 16 and the Asheep pen or corral, and the clock mechanism 36 and the spring 35 vare Wound`up about dusk in the evening by means of a key. The clock will run, thereby driving the disk 37 and bringing one of the pins 39 into contact ICO with the lever-arm 30h to disengage the lever 30 to release the shaft 23, when the spring 35 will rotate the shaft and bring one set of the teeth 21 into engagement with the rack 18, thereby raising the plunger 16. As soon as the gear 2O has performed a quarter of a revolution the rack 18 will be released to permit the plunger to descend and explode one of the cartridges in the cylinder 5.

Simultaneously with the rotation of the gear 2O the ratchet 29 will also be rotated to engage the connecting-rod 32 to operate the wheel 12 to turn the cylinder 5 a distance equal to the interval between the barrels in the cylinder, and thereby bring a cartridge beneath the plunger 1G for it to be operated on. The spring 32 will restore the wheel 12 to its initial position, so that it is ready to bring forward the next cartridge. This operation will be repeated every quarter of an hour throughout the night. In the morning the device is stopped.

I do not wish to be limited as to details of construction, as these may be modied in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is

1. In a device of the class described, the combination, of a cylinder mounted to revolve and containing chambers for cartridges, a slotted tube, a spring actuated plunger mounted in said tube and bearing a rack, a gear bearing alternate toothed and smooth sections, and means for operating said gear to actuate said plunger to explode said cartridges, substantially as described.

2. In a device of the class described, the combination of a cylinder constructed to contain cartridges, a tube containing a springactuated plunger bearing a rack, a gear bearing alternate toothed and smooth sections, a shaft supporting said gear, a spring mounted on said shaft, a ratchet mounted on said shaft, a lever engaging said ratchet, and means for intermittently operating said lever to release said ratchet to operate said plunger, substantially as described.

3. In a device of the class described, the combination of a cartridge-cylinder bearing a circular rack,a Wheel bearing a pawl,aspring driven shaft bearing a ratchet, a connectingrod pivoted to said wheel and located to be engaged by said ratchet, and means for driving said ratchet, substantially as described.

4. In an alarm mechanism, the combination ofachambered cylinderforholdingcartridges, a clock mechanism, a wheel bearing a series of pins and driven by said clock mechanism, a spring-actuated plunger bearing a rack, a mutilated gear meshing with said rack, a ratchet mounted to travel in unison with said gear, a lever engaging said ratchet and located to be engaged by the said pins on said wheel to be disengaged from said ratchet, substantially as described.

5. I-n an alarm mechanism, the combination of a chambered cylinder carrying a ratchet, a Wheel bearing a spring-actuated pawl meshing with said ratchet, a brake-lever, a con meeting-rod connected to said wheel and engaging said brake-lever to operate it, and means for intermittently actuating said connecting-rod to rotate said cylinder, substantially as described.

6. In an alarm mechanism, the combination of a cylinder carrying a ratchet, a wheel bearing a pawl, a connecting-rod pivoted to said wheel and having a hooked head, guides for said connecting-rod, a ratchet engaged by the hooked end of said connecting-rod, and means for intermittently actuating said ratchet to rotate said cylinder a fraction of a revolution at a time, substantially as described.

7. In an alarm mechanism, the combination of a chambered cylinder for containing cartridges, a plunger located to strike the cartridge in said cylinder as it is revolved, a rack carried by said plunger, a spring bearing on said plunger, a mutilated gear meshing with said rack to raise said plunger, means for intermittently actuating said gear, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witmesses.
