Steel Gloves Serve as Prisoner Handcuffs
(Research provided by Lyndall Cole.)
In early 1924, Phillips County Sheriff Jacob “Jake” Oliver McKenzie of Phillipsburg, Kansas invented a new style of high security handcuffs for prisoner transports. Sheriff McKenzie received his inspiration for his unique invention after a prisoner grabbed his gun during a transport and in the ensuing struggle shot Sheriff McKenzie in the leg. These new handcuffs were basically steel gloves that a prisoner would slide their hands into, limiting the prisoner’s ability to grasp anything with their hands. The innovative sheriff received a patent for his steel gloves in March of 1925, for what would become known as McKenzie Mitts. (A man named John Bushey wrote an informative article about these McKenzie Mitts in 2011.)
One of the best known and most popular Tulsa County deputy sheriffs in 1925 was James Alexander Sewell. On Tuesday, March 24, 1925, Deputy Sewell was transporting three inmates to their respective correctional facilities. Daniel Scott, 14, was being transported to the Pauls Valley industrial school, and the other two prisoners, Howard Love, 16, and Ernest Hughes, 20, were being transported to the Oklahoma Reformatory in Granite, Oklahoma. After dropping off Scott, Sewell proceeded on towards Granite with Hughes and Love. During the drive to Granite, while Deputy Sewell was removing his coat, one of the prisoners grabbed his gun and shot him. Deputy Sewell died several hours later after the two prisoners left him beside the road, near a farm house.
Both, Love and Hughes, were later apprehended after a state-wide manhunt and charged with murder in Grady County where the shooting had occurred. Both defendants blamed each other for shooting, but Howard Love was convicted of the actual murder of Deputy Sewell. Both men received a life sentence.
In 1926, because of the death of Deputy Sewell, Sheriff Bob Sanford purchased steel gloves to cover the hands of inmates during transports to protect his deputies. “They are steel gloves which will be used on desperate criminals. They fit over the hand of the criminal and prevent his reaching for or using a weapon. The gloves are quite light and do not injure the hand, the sheriff said. They cost $25.” (Tulsa Tribune, January 28, 1926.)
I believe the steel gloves purchased by Sheriff Sanford in 1926, was McKenzie Mitts. Shown below is a pair of these steel gloves in an ad in the December, 1927 issue of Popular Mechanics magazine I was able to purchase. This ad appeared on page 976.
