SIGHT FOR FIREARMS.

I My invention relates to the type of sights for' firearms in which the wedge is used to position the sight at the desired elevation and my inventlon consists 1n improvements which make said type effective and practi-' cal instead of ineffective and of doubtful utility as said type has been heretofore. Heretofore with sights of this type the Wedge positions the sight at an unknown elevation and a stranger to the firearmcannot use it eflectively while with my invention I provide for a given make and caliber of rifle the sight may be adjusted back and forth in shooting until the amount of rise shall have been determined and then, as in the form shown for example, the proper notches to correspond may be made in the bottom of the wedge and thereafter wedges so notched will be installed on every such rifieias it leaves the factory and it will reach the hands of the purchaser in shape for instant and effective use of any range Within its practical limits. In other words I provide limits forthe movement of the wedge so that without taking ones eye from the object aimed at one can count'the clicks as the wedge passes along the barrel and can thus determine ust what position of elevation the sight will be in. Another means of indicating the position of elevation .consists in a scale which at a glance will indicate the position of elevation.

In the drawings: Figure 1 is a plan of a sight .embodying'my invention; Fig. 2 is a sectional elevation of the same; Fig. 3 is a section on line 3-3 of Fig. 2 on a larger scale; Fig. 4c is a partial section on line 4-4 of Fig. 2; Fig. 5 is a partial section on line 5 -5of Fig. 1; and Fig. 6 illustrates a modification.

Barrel A is in dove-tailed connection with the end a of spring member a, the latter havinga sight at a The spring member is slotted at a and has two semi-circular bear ing porti ns a Mounted to slide along the barrel and within slot a is the rackwedge member B having teeth to engage corresponding teeth .on the pinion B which is mounted'on shaft .6, the-latter carrying the Specification of Letters Patent.

Application filed September 26. 1913. Serial No. 792,047.

cylindrical portion 6 which is substantially flush with the adjacent bearing portion a, so that the scale on portion b may be easily read in connection with the mark a on the adjacent bearing portion a. Turn-button D 18 provided to turn the shaft and pinion B. Pin 6 is rigidly fixed to the barrel and is adapted to engage notches in the bottom of the wedge member B, each of the end notches e having its outer wall substantially vertical and intermediate notches 6 being also provided. When the pinion B is rotated the rack member B is moved to change the elevation of the sight and it can ride over the pin 6 because of the yielding of the spring sight member which furnishes the bearing for the pinion, and the rack member B can move in either direction in case the pin 6 engages one of the notches 6 but; the movement is limited by the end notches e because of the vertical walls above described. If desired a pin F may be provided on the portion 7) to ride in a slot f in the adjacent bearing portion and this provides a convenient means for limiting the movement of the rotary member and therefore-the wedge member in both directions.

In Fig. 6.1 show the toothed portion of the rack member B curved and in this case the notches on the bottom of the wedge member are spaced apart equally, thus giving varying amounts .of elevation of the sight for equal amounts of rotation of the gear, while it will be observed that in the form of Fig. 2 the space between the two rear notches is less than between the next two and so on, it being desirable to have this increasing distance .of travel on account of the increasing drop as the bullet progresses.

I provide a groove 6 in the bottom of the wedge to engage web e and thereby assist the guiding of the wedge member.

In using my device it will be clear that the operator may rotate the pinion and thereby move the rack member until it reaches the limit of its movement in either direction and then the pinion may be rotated and as the wedge member passes over the pin 0 the operator can tell by the feeling and by hearing and independently of 111s vision just what position the wedge member occupies and therefore what the elevation of thesight is,and this is of the utmost importance in the use of firearms particularly for hu ting purp ses.

tion of the rack member carrying the teeth curves from the right downwardly and then upwardly and the drop is provided for sighting at very short distances, say up to 50 yards or thereabout while at that distance the sight is preferably raised, the rise beginning when the falling of the bullet compensates for the difference between the line of sight and the axis of the bore, this form of curve being preferable in cases where the firearm is to be used for sighting at very short distances as well-as long distances and both the lowering and the raising being accomplished by' rotationof the gear continuously in one direction.

I have disclosed an operative surface of the wedge member in which one portion slopes downwardly and another upwardly but my invention contemplates an operative surface in which portions are inclined to each other whether downwardly or upwardly or otherwise.

What I claim is:

1. A- sight for firearms comprising a spring member carrying a sight; a wedge member movable to change the elevation of the sight; rotary means to movethe wedge; and means including said spring member when the latter is moved in the direction of its resiliency toward and from another-portion of said last mentioned means to indicate the position of the sight to the user independently of his vision, said indicating means permitting rotation of the rotary member in either direction.

2. A sight for firearms comprising a spring member carrying a sight; a wedge movable to change the elevation of the sight and having a series of notches; means to reciprocate the wedge; a pin to engage the series of notches and hold the wedge in the desired position; and means to limit the movement of the wedge in both directions of reciprocation. y

3. A sight for firearms comprising a barrel having a pin; a spring member carrying a sight and provided with a bearing; a gear with a shaft, said shaft being mounted in said bearing and having a turn button at one end; a wedge member engaging said gear and reciprocated thereby along said barrel and having on its under surface a series of notches, one of the end notches engaging said pin to limit said movement of reciprocation in one direction and holding the wedge member in that position and the other end notch engaging said pin to limit said movement of reciprocation in the other direction and hold the wedge member in that position, and the remainder of said series of notches engaging said pin as desired to hold the wedge in the position desired but permitting movement of the wedge member when desired in either direction.

4. A sight for firearms comprising a sight member; a wedge member with a curved toothed surface; and a gear to engage said curvedsurface and move said wedge to give varying amounts of elevation of the sight for equal amounts of rotation of the gear.-

5. A sight for firearms comprising a spring member carrying a sight; a wedge member whose movement changes the elevation of the sight and which is adapted to reciprocate; means to reciprocate the wedge, said means engaging said springmember; and means acting automatically under the influence of said spring member to hold the wedge in the desired position of its travel. p

6. A sight for firearms comprising a spring member carrying a sight; a wedge member movable to'ehange the elevation of and means acting automatically under the influence of said spring member to hold the wedge in the desired position.

8. A sight for firearms comprising a sight; a gear to move said wedge member;

sight member; a wedge member having portions of its surface inclined to eachother; anda rotary member to move said wedge to change the elevation of the sight, rotation of said rotary member in one directionlowh ering and then raising the sight member.

9. A sight for firearms comprising a spring member carrying a sight;"a wed e movable to change the elevation of t e sight; rotary means to move the wedge;

means to limit the movement of the wedge;

and means to indicate to the user independently of hisvision the amount of movement from such limit, a portion of the limiting means being also a portion of the indicating means.

10. A sight for firearms comprising a spring sight member having a bearing portion; a wedge member movableto change the elevation of the sight; a rotary member to move said wedge member and mounted in said bearing and having an extension outside of said bearing; and means independent of said extension to hold the wedge in the desired position.

11. A sight for firearms comprising a spring member carrying a sight; a wedge member movable to change the elevation of the sight and adapted to reciprocate; means to reciprocate the Wedge, said means engaging said spring member; means to limit the movement of the Wedge in both directions of reciprocation; and means acting automatically under the influence of said spring member to hold the Wedge in the desired position of its travel.

12. A sight for firearms comprising a sight member; and a movable member having an operative surface with portions inclined to each other, movement of said movable member in one direction lowering and then raising the sight member.

13. A sight for firearms comprising a sight member; a Wedge member having a surface With portions inclined to each other; and movable means to move the Wedge,
