H. w. MCCULLOCH NUT LOCK Filed Jan. 26, 1921 Patented Dec. 23, 1924.
UNITED STATES HAROLD WEED MOCULLOCH, OF NEW YORK, N. Y.
NUT
Application filed January 26,1921. Serial m. 440,128.
To all whom it may concern:
Be it known that I, HAROLD Wnno McCuL- LOCH, a citizen of the United States, residing at the city of New York, county of Bronx, and State of New York, have invented new and useful Improvements in Nut Locks, of which the following is a specification.
M invention relates to improvements in nut ocks, and has for an object an increase in effectiveness of devices of this kind.
In preventing the loosening of nuts by turning due to jars, vibrations, etc., a common recourse is had to locking devices which 7 are interposed between the nut and the abutting face of the object against which the nut is to be screwed. Considerable annoyance is caused, when the nuts are being put on or taken oil, to clamp and unclamp two elements, by reason of the locking devices becoming lost or misplaced. An object of my invention is to provide a locking device efficient and inexpensive.
vwhich avoids danger of its loss or misplacement, and which is simple, reliable, durable Other objects and advantages will be apparent from the following description, and the novel features of my invention will be particularly pointed out in the claim.
In carrying out my. invention I provide the surface of one of the elements against which the nut abuts with one or more resilient nut engaging prongs which border the edge of the aperture through which the bolt carrying the nut passes. These prongs may comprise resilient strips formed by striking them up from the element when the latter is of sheet material so as to present an end edge to the under face of the nut. One or more of the prongs may be struck up from the portion of the sheet element bordering the bolt aperture or one single prong may be struck up, all extending from the interior of the sheet to the bolt aperture and thence partially around a portion of the aperture.
In the accompanying drawings, Fi 1 is "a respective illustrating one embo imenti of my invention.
Fig. 2 is a plan of the same.
Fig. 3 is an elevation of two elements clamped by a nut and bolt and having my invention embodied therein.
Fig. 4 is a perspective illustrating another embodiment of my invention.
5 is a plan of the same. g g. 57 is an elevation of the same.
other embodiment of my invention, and
Fig. 8' 1s a perspective illustrating still another embodiment of my invention.
Referring now to the drawings. particularly Figures 1 to 5, the elements 1 and 2 are clamped together by means of a bolt 3 paslsing through apertures 4 in the elements an ably of metal which can be hardened. In the embodiment of. Figs. 1 to 3 one or more prongs 6 are struck up from the portion of the sheet bordering the aperture, one side of each prong beingcoincident with a portion of the edge of the aperture. The ends of the prongs project upwardly at an angle to the face of the element so as to present the sharp end corner edges to the under face of the nut, and by their resilient engagement with the nut they will act somewhat like the well known split washer and lock the nut against accidental loosening such as may be due to jars, vibrationsf etc.
In Figs. 4 to 6, which illustrate an embodiment of the invention to which the claim is directed, the element 1 is provided with but one single prong 7, of greater length than the prongs 6, which prong extends from'the interior of the element to the aperture 4 and then around the major portion of the edge of the aperture with an upwardly turned end so as to present the sharp end corner edge to the under face of a nut. T l is prong in this embodiment is also struck o t of the element by stamping with a shea mg die, and the prong graduall rises from the element 1 toward the free end so as to provide resiliency and press against the under side of the nut to lock it when it is screwed down.
Having described my invention, what I claim is:
A sheet element having an aperture therein through which a threaded stem may pass, and also having a struck up resilient nut engaging prong extending from the interior of the sheet to the aperture and there around I a portion of the edge of the aperture.
In testimony whereof I have hereunto set my hand.
HAROLD WEED MoOULLOCH.
