RIFLE GRENADE CLINOMETER -Filed April 25. 1930 2 Sheets-Sheet 2 INVENTOR ATTORNEY Patented Dec. 26, 1933 (Granted under A th anti March gs; 1883,
V will satisfactorily solve the problem oflprocuring accuracy in firing rifle grenades. H J An object of my invention isito provide a rifle grenade clinometer thatoncef-attached to the rifle maybe left onthe rifle without interferirig V Ltegral part of the base ;'fits' around the lower with the normalfiri'ng of the rifle.
A further object or my invention is to provide a device that enables an individual firing a grenade from arifle to hit Within a radius of one yard from the target, thus eliminating guess work now employed in the firing of a grenade from a rifle and thereby making a weapon of uncertainty one of unfailing accuracy.
Another object of my invention is to provide a rifle grenade clinometer that incorporates the feature of interchangeability of rotary range scales, making it adaptable to varying weights of grenades and various kinds of ammunition, by the simple process of inserting different rotary range scales. V
A further object of my inventionresides in constructing a rifle grenade clinometer that is not involved in its operation, easy to manufacture and not difficult to replace-parts; simplicity with efiectiveness governing the manufacture and use of the device.
It is also an object of myinvention to provide a device that. is rugged, of light weight, and can be carried handily in its carrying case attached to the rifle-grenadiers cartridge belt. 7
With the above and other objects in View, the invention consists in the construction, combination and arrangement of parts as will be described more fully hereinafter. a
Reference is to be had to the accompanying drawings forming a part of thespecification, in which like reference characters indicate corresponding parts throughout the several views, and in which:
Figure 1 is a side elevation of myimproved de vice shown partly in section;
Figure 2 is a plan view of my improved device Figure 3 is an end view of my improved device; Figure 4 is the application of my improved device on a rifle.
Referring more particularly to the drawings, 10 indicates a body member or base to which is secured by means of a hinge 11 a top or rotary range scale holder 12. Inserted in the holder 12 and a portion of the that is held against displacement by and revolves V band 21 of thelrifle 2o.
readily shifted by opening the body 10 is a rotary range scale 13,
byiscr'ews' 17 to the baslO keeps the holder 12 firmly down in the closed'position thereby'holding thescale 13 'movably in "position. j Affixed by countersunk screws 18 to the base are/clips 19 that are adapted to snap and flt around a stock of a rifle 20 just above the lower I k A band hook 22, an inband screw of the rifle 20 and prevents the 01'1"- nometer from slipping. l
' A notch 23 is cut in the holder 12 to be used as a reference point when setting the rotary range scale 13. A level 24 is anintegral part of the scale 13 and is mounted with its longitudinal maximum to the zero range of the grenade in each direction from the maximum graduation on the scale, so that decreased range may be obtained by either raising or lowering the muzzle of the rifle. For example, assuming a maximum range of 300 yardscorresponding to an elevation ofv 45 degrees, a range of say 200' yards may be obtained by firing at either a greater or less elevation. According to which is desired, the appropriate graduation is aligned with the notch 23, and the proper elevation of the rifle determined by centering the level-bubble.
"Difierent range scales are necessary for each type of grenade depending particularly uponthe weight of the grenade. The scales 13 can be holder 12 on the hinge 11. Although I have marked the range Q scale in yards, I desire it to be understood that the scale can be marked in miles, degreesor any other suitable scale.
In the practical use of my improved device the rifle grenade clinometer is snapped over the stock of the rifle, and then moved toward the butt of the rifle until, the lower band hook 22 is firmly engaged with the lower band screw of the rifle. The clinometer is then used for laying the rifle when firing grenades.
To lay the rifle for any range the rotary range scale 13 is turned by means of the level 25 until the desired range marking is opposite the notch 23 cut in the rotary range scale holder 12. When the level-bubble is midway between the lines 31 on the level vial 25 the grenade if fired will fall at the range indicated.
The rifle grenade clinometer is so designed and constructed that the rifle may be used with the clinometer attached during ordinary firing of the piece. Because of its position on the stock,
the grenadier is not prevented from firing his piece normally, and can shift from grenadier to rifleman and vice versa without the slightest delay. The chances are slight of the clinometers being jarred from position on the rifle stock, but should this occur, the grenadier should slip it back into proper position before adjusting the rotary range scale or leveling the bubble.
It will be understood that the abovedescription and accompanying drawings comprehend only the general and preferred embodiment, of my in. vention, and that various changes in construction, proportion and arrangement of. parts may be made within the scope of the appended claims, and Without sacrificing any of the advantages of my invention.
The herein described invention may be manufactured and. used by or for'the Government of the United States for governmental purposes without the payment to me of any royalties thereon.
What I claim is: 1. A grenade clinometer adapted to be attached to a rifle comprising a base, means for at-,
member, a hinged top rotatably mounting said member to the base, a spring secured to the base and bearing against the top so that the member may be easily removed, a range scale integral with said member and extending out from said base and top, a level mounted on the side of said scale, whereby predetermined ranges may be set with. regard to a reference point by said scale and correct angles of elevation may be determined by said. level without moving the rifle from its firing position, and clips secured to said base for detachablysecuring the clinometer to the rifle.
