which means are provided for' adj-ustably supporting the sight upon the bar'rel of the firearm in such amanner that its relative -position with respect to the-forward or iiXed side of the gun barrel can be varied to allow for different ranges of iiring.

In its generic nature, my invention comprises a spring body adapted to be secured to the gunbarrel to the rear end of which an apertured disk member is secured, the disk .member being formed in two sections pivotally connected together along a horizontal line, so that the upper section can be folded down when the sight is to be used as an opensight and can be folded up to complete the disk form when the sight is to be used as a peep-sight.

Primarily, my invention has for its object to provide a sight of the character stated, of a very simple and effective construction, which can be easily and cheaply manufactured and which will readily and e'ectively serve its intended purposes.

In its more detailed nature mylinvention embodies certain novel construction, combination and arrangement of parts, all of which will be first described in detail and then be s .ecifically pointed out in the appended c aims, reference being` had to the accompanying drawings, in which: 'l

ligure 1, is va side elevation of a lire-arm with my invention applied, showing the position of the parts when the sight is to be used 'asi'a peep-sight. tical, longitudinal section, the partev beingfin the position shown in Fig. 1. Fig. 3, is a similar view, the sight being folded down into the position to form an open-sight. Fig. 4, is a top, plan view thereof. lig. 5, is an enlarged perspective view of the sight detached looking from the barrel side. l? ig. 6, is a similar view looking from the stockside.-

Big. 7, is a detail view of a modified form 5- of my invention.

Referring now to lig. 2, 'is an enlarged, ver-A 1 designates the barrel of the re-arm .upon the forwardy end of which the usual front sight 1a is secured.

2 designates `the stock of the fire-arm and 3 the trigger and guard, all of which maybe' of any approved construction.

Secured to the barrel 1 adjacent the stock or in any other approved position, is the rear sight which forms the subject matter of my invention. This sight, it will be noticed,

secured -at its forward end to the barrel 1 by a tongue 4a ,which enters a groove 1b ofthe provided with a dove-tailed lug 4b which eni ters a dove-tailed slot 5a in the sight member proper 5 and is securely connected to the ower ortion of the member 5 by a set screw 8, asc early shown in the drawings. The sight member 5 consists in my present tions 5b--5c hingedlyy secured as at 5d, the

at 5e to form hinge projectionst which cothe securing or hinge pin 5g is passe The hinge portions 5i ofthe sections 5b'5 are so arranged that the rear face of the disk member 5 when open to form a ecpsight, will lie in a flat plane and the hinge members be projected'toward the front of the sight so as to not interfere with the options being provided with shoulders 5 to abut .one another when the sections areextended to forni a peep-sight.' In practice, the hinge joint of the sections 5*-5c is made sufficiently tight sov that'when the parts are in the position shown in Fig. 1, to be used as a peep-sight, the sections will remain in their respective positions by friction.

When the several disk 'sections ,5L-5'? are extended to complete the disk` form, it will vided to form a'peep-hole t ough the isk, through which the gun may be sighted, onehalf of thecircumfer'ence of the aperture 6 sight, it being understood thata horizontaly line drawn axially through the aperture 6 will include the upper edges of the hinge the accompanying draw.A

throwing the pivotal airis of the pins 5 in s,

ings in which likeletters and numbers of reference indicate like parts in all of the figures,

-consists of a sheet spring member 4 which is4 operate with one another and throu h which being disposed on he lower section 5b and the other half on the uppersection 5 of thegun barrel. The spring 4 at its rear end is invention of a disk formed of a pair of secrespective sections 5*4-.5c being cut away as eration of the instrument, the several sec- Y loo be noticed that a central a erture 6 is ro- IIO members 5*. of the lower section" 5h,v thus eachfearbeing provided wit lineslightly *below'thecenter of the aperture4 6 and of the disk member when extended, thus` when the rsection [ic-is folded down, as shown in Fig. 3, to lform an open sight, the section 5c will have its'edges 'slightly proy jected beyond those of the section 5b, so as.

-to enable the opera-tor to readily grasp the same to instantaneously throw it up to the positionv shown in Fig. '1, when it is desired vto use the' sight as a peep-sight gun. i`

The spring member 4 is provided -on its up per face with two series of graduations 1X-.4F the first :series .4x being calibrated for .use

in connectionfwith soft point bullets, while the second series, '4y being calibrated for use withsteel point bullets, asl.-

in connection y find the drop" of soft and. steel 4point bullets differ.

#In Ord-erta adjust thesighf for Various On the front ofthe sight 5 I forml a depres- I sion soy as to make the edges of the aper-` ture 6 as thin as possible for a purpose read-4 ilyl understood by those skilled in the art vto which the invention ap. ertains.

In the practical application of my invention when-it isV desired to use the, lire-arm witha peep-sight, the 'section 5,is swung up to lthe position shownin Fig. 1, and the op erator 'then si h alinenient with ,the front sight la1 and to the object in a manner well understood. ,It should beI .-understood, however, thatv previous to sighting the gun the operator moves the carriage 7 along the jspring.- until the proper -scale mark is reached to give him the proper'range, aifter which the fire-arm is in condition forv use, and to change immediately from a peepsight to an open-sight this can be readily donewithout moving the carriage'l' or, changing the range-.by simply throwing down the 'upper hal of .section 5? -'of the, sight disk into the position shown in Fig. ,3, when the device maybe used asan open-sight if. desired.

, From the foregoing it will be seen thatmy invention Lis, of an extremely simple construction-and there-is nothing about it. to

get outnofforden@ ltcanbe'also yeasily andch'eaply manufactured 'and willnot take any -moreiooi'n on1the fire-arm than an ordinary'openfsigh-tx Furthermore it can bef"J GhangedrOm anopen 'to a peepesight and vice ive'rsa, valmost; linstantaneously and it. will hefounde 'to fbe? a=goody hunting sightv as having a cent'ral sai sig ts through the aperture 6 inf well as a target sight since it includes every tion, operation and many advantages 'of my inventlon will be readily .understood by those skilled in the art to which itappertains andI desire to sayl thatmany slight changes in the detailed' construction, com-A bination and arrangement-of parts maybe made without departing romthe spirit of the invention or the scope ofthe appended claims.

-In Fig. 7,f I have shown aniodified form of hinge connection in which. the hinge pin 5F ma?T be provided with a head 5 and a mil ed nut 5D so. that the hinge joint may become tightened in case of wear after long continued use.
