Lincoln patented the first lever grease gun to work with a full stroke operation called the Model 1242. This meant that a hand-held grease gun could generate up to 10,000 lbf/in² (70 MPa) of pressure. Operators of the unit could push grease into blocked or "frozen" fittings and the unit allowed for work in confined areas.
The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. [12] The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun , but was cheaper to mass produce and lighter, at the expense of accuracy. [ 12 ]
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", [5] and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon Ingram in 1964.
Some M8 scabbards were later modified by adding the hook. The scabbard throat is stamped "US M8" or "US M8A1" on the flat steel part along with the manufacturer's initials. Later M8A1 scabbards were manufactured with a modified extended tab on the web hanger to provide more clearance for the M5 bayonet which rubbed against the wider bayonet handle.
A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'. The channels behind the grease nipple lead to where the lubrication is needed.
In February 1944, the M1A1 reached a low price of $45 each, including accessories and spare parts, although the difference in price between the M1 and M1A1 was only $0.06. By the end of the war, the M1A1 was replaced with the even lower-cost M3 (commonly called the "Grease Gun").
Agar advertised the gun as "an army in six feet square", due to its high rate of fire. [3] In 1861, the Agar machine gun was demonstrated to President Abraham Lincoln, who was very impressed by the weapon. Lincoln wrote "I saw this gun myself, and witnessed some experiments with it, and I really think it is worth the attention of the Government."
