To all whom, it many concern/.2

Be it that we, JOSEPHDL'PENDER, residing the city and county of Denver, and ROLLANI) IS. Tno'rr, residing at Golden, 5 in the county of deflers'on, State of Colorado, citizens of the United States, have invented certain new and usetu-l Improvements in Rear Sights for Firearms; and we do declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, to the letters and figures of reference markedthereon, which form a part of this specification Our invention relates to improvements in sights for firearms.

This invention belongs to the class generally known as rear sights to distinguish it from the; sight at the iorwa-rdend oi the barrel. The rear sight of course cooperates with the usual forward sight, the latter not being illustrated in the drawings, as nothing isclairned thereon. ,1 I

The object of our improvement is to provide a device of this class which may be quicklyadjusted, and therefore adapted for use under circumstances making it impracticable to expend any appreciable amount of time in the work of adjustment. For in: stance, if the object at which the gun is aimed is moving, as is often the case, our improved sight is adapted for instantaneous and accurate adjustment to harmonize with the range or distance of the object at the-instant the trigger is'pu-lled.

Our improved sight is spring-actuated, whereby. the sight is raised a predetermined distance by the spring every time the sight is released. In our improvement the sight is I rovided with ratchet-teeth, and the controling device includesa reciprocating part cupying a position at right angles to the 45 movement of the sight under the influence of thespring. Assuming that the sight has been raised, it may be restored to its normal or lowered position by simply pressing down thereon, whereby the teeth of the ratchet are made to engage the controlling device, producing'a clicking sound.

Having briefly outlined our improved construction, as well as the function itis intended to perform, we will proceed to describe the F g I e which is next to the receiver of the gun when,

the sight is applied. In this view the mechanism 18 shown on a larger scale than Figs.

1 and 2.. Fig. 4 is asect-ron taken on the line 4 4, Fig. 3, looking downwardly or the direction of the arrow. Fig. 5 is a perspective view in detail of the reciprocating device shown on a larger scale. Fig. 6 is a sectional view taken through the casing and the reciprocating device of the sight, the sight proper being shown in elevation. This view is shown on astilllarger scale and is seen from a position directly opposite the view in Fig. 3. Fig. 7 is a detail view, in rear elevation, showing a modified for n -oi construction. Fig. 8 is a side view, in detail and partly broken away, of the constructidn shown in Fig. 7. Fig. 9 shows two views of a pivoted pawl forming a part of the construction shown in Figs. .7 and 8. Fig. this an enlarged fragmentary detail view illustrating the operation of this term 0t =construction. The same reference characters indicate the same parts in all the views;

Referring first to Figs. 1 to 6, inclusive, let

the numeral 5 designate the. receiver o r' a gun, as a small firearm. of ordinary construc tion. To one side of this receiver is attached our improved sight by means of screws 6 inserted in slots 7, formed in the casing 8. The

screwsare threaded into the receiver, and by virtue of the slots in the casing the latter is capable of the necessary vertical adjustment to adapt the sight for use with firearms of different makes and sizes.

As shown in the drawings, the casing is closed on the side remote from the receiver, while the flat side of the receiver itself closes the casing on the inside. The casing is open at the top to allow the ratchet-bar (designated by the numeral 8 to rotrude. This sight consists of a vertical y-disp'osed and a centrally recessed to receive an actuatingspring 9, which surrounds the pin 10, securedtothe casing at its lower extremity. The recess 12 ofthe bar is of sufficient size to allow the sprin 9 freedom of movement,

whereby i'tis a apted to lift the bar 8 as soon as thelatte'r is released by the red 1'0 catinglocking or controlling device 13.- his controlling device consists of a bar horizontally disposed or disposed at right angles to ;-.the'-movement of the ratchet-bar 8. This bar is'cut away or recessed on one side, as

same hand used to pull the trigger.

. whereby the toothed. or

shownat-13, to make room for the ratchet-g bar, Itfis also rovided' with oppositely disposed teeth or eveled parts 13, adapted to engage theratchet-teeth of the bar 8,

formed on opposite sides of the latter,'as

aforesaid. The' rear extremity of this recip- Y rocatingcontroller is provided with a head- 13, adaptedto be conveniently pressed by the user 'of the gun, using the thumb of the The outer surface of this button or ush-head of the controlling device is prefera ly milled or roughened, as shown in Fig. 1, to prevent the thumb; from slipping therefrom.' The for-- ward and rear edges of the casing are respec-v tively'provided with o enings 14 and 15,

beveled portions 13 of ther'eci rocating device are given access to the ratchet-teeth of the bar 8 during the reciprocating'movement of the latter. Thev rear extremity of the reciprocating device 13 bears against a leaf-spring 16 under such tension as to normally hold the device 13 at its rearward limitof movement, or that illusbe released. and allowed to move upwardly trated in Fig, 6 of the drawings. Now if it is desired to elevate the si ht the user of the gun simpl presses on the ead of the device 13, where y the latter is given a rearward movement a ainst the spring 16. Assuming that the devlce 13 is in the. position shown in Fig. 6, as this device is pushed rearwardly the rear tooth 13 will disengage the ratchettooth A just as the forward tooth 13 enters the recess B above the tooth A on the op 0- site side of the ratchet. The bar 8 will t us until the rear tooth 13 of the contro lin device en ages the upper face of the toot A. This wi 1 stop the upward movement of the ratchet-bar until the operator ceases to press upon the reciprocating device, in which event the s ring16 will throw the device 13 rearwardl ,-whereby the tooth A of the ratchetbar is released, in which event the bar 8 will move upwardl until the reartooth of the reciprocating evice engages the upper surface of the ratchet-tooth A thus allowing the sight to move upwardly the length of one ratchet-tooth during each operation of the controlling device 1 From this descri tion it will be understood that the vertical a justment of the sight may be ver quickly and easily obtained by the user 0 the gun, whereby it becomes practicable to accurately arrange the sight for all ranges or distances,thus making the same exceedingly valuable where a rapid adjustment is necessary, as where the distance of the object is constantly varying, as when an animal at which the gun is aimed is on the run,

After the sight has been raised to the del sired limit and has answered its purpose it may be returned to its normal or lowered position, whereby the part 8 is made to engage the top of the receiver by downward o pressure on its upper extremity, which causes 7 the bar 8 to slip past the teeth of the reciprocating device in a manner well understood.

In the form of construction shown in Figs. 7 to 10, inclusive, the body of the casing may be designated by the reference character 17. This casing is open on the inside adjacent the outer wall of the receiver. The outer art of the casing is closed by a late 17 0 a size indicated by dotted lines in Fig. 8, whereby the leaf-spring 16, as well as the othermechanism, is entirely inclosed. In this case the plate 18, provided with the ratchet-teeth, is applied to the front side of the verticallymovable sight-bar 19. This bar is recessed vertically to receive an actuating coil-spring 20, whose lower extremity engages the bottom of the casing, while the upper extremity engages the top of the longitudinal recess, whereby as the sight-bar is released the ten- 11o sion of the spring carries it upwardly. In this case we employa reciprocating controller 21, having forwardly-projecting upper and lower arms or

fingers

22 and 23, respectively.

As shown in the drawings, the part 23 is se- :15 cured to the body of the reciprocating device by a screw 24. The arm 22 engages the upper portion of the leaf-spring 16, whose lower extremity is secured to the casing bya screw 25. The spring 16 also normally engages one corner of a pawl 26, pivoted to the casing,

as shown at 27, and having up er and lower teeth 28 and 29, adapted to a ternately engage the teeth of the ratchet-plate 18. In this orm of construction the pivoted pawl 26 is so 12 5 arranged with reference to the spring 16 that the latter locks the pawl in either of two positions of adjustment, one being the position shown in full lines and the other in dotted lines in Fig. 10. This pawl 26 is provided with a number of teeth C, out therein and lying in a different plane from the ratchetengaging teeth 28 and 29. One of these teeth C is always in front of the arm or finger 23 of the reciprocating device. When the awl occupies the position shown in full lines in Fig. 10., the actuating-finger 23 engages the upper inclined wall C of the tooth 0, whereby the forward thrust of the finger 23 serves to rock the pawl or throw it to the dotted-line position, whereby the apex C of the tooth C'is above the point 23 of the finger. When in this dotted-line position, the spring 16 acts 'on the pawl to hold it in the said position. The full forward position of the finger 122 and the spring 16 is indicated by dotted lines in Fig; 10 at the extreme left thereof. The rearward nrovement of the spring before it engages the pawl in the dotted-line position is sufficient to return the reciprocating device to its rearward limit of movement ready for the next forward thrust. During the movement of the pawl from the full-line to the dotted-line position in Fig; 10 the sight-bar 19 moves upwardly half the length of a ratchet-tooth and is locked in that position by the lower tooth 29 of the pawl. The next forward movement of the reciprocating device 21 will cause the finger 23 to engage the lower wall C of the middle tooth C and throw the pawl from the dotted-line position to the full-line position, during which time thesight-bar will move upwardly another half-tooth, the spring will return the reciprocating device to its normal position and engage the pawl and hold it in the fullline position until the next forward thrust. It will thus be seen that two reciprocations of the device 21 are necessary in order to allow the sight-bar to move upward the length of one ratchet tooth. This construction and arrangement gives a very close and accurate adjustment of the sight.

From the foregoing description the use and operation of our improved device will be readily understood, and therefore need not be further described in detail.

Attention is called to the fact that in the form of construction shown in Figs. 1 to 6 of the drawings the distance between the teeth of the ratchet-bar increases as the teeth extend downwardly. The object of this is to cause the vertical adjustment of the sight to harmonize with the accelerated downward movement of the ball or projectile as it leaves the muzzle of the gun. It is well known that the speed. of a falling body increases in a regular ratio. Hence the necessity for a greater upward movement of the sight for each reciprocating movement of the controlling device during the upward progress of the sight.

Attention is called to the fact that the head of the reciprocating device when actuated is concealed within a recess 30,- thus making it impossible to accidentally actuate the said device. This is quite an important feature, since if the head protruded from the casing far enough to permit it to be actuated without design the sight would be capable of accidental change of position, and this might not be noticed by the user of the gun and might, therefore, result in great inconvenience and annoyance. When thereciprocating device is at its rearward limit ofmovement, its head only protrudes slightly from the recess 30, thus making it impossible of accidental movement to a sufficient degree to release the ratchet-bar.

Having thus described our invention, what weclaimis 1.
