LOQM NUT" SPECIFICATION forming part of Letters Patent No. 783,630, dated February 28, 1905.

Application filed August 22,1904. Serial No. 221,747.

Be it known that I, Cn'iimncsW. Glens, a citizen of the United States, residing at Bridge port, in the county of liairlield and State of (,kmnccticut, have invented a certain new and useful Improvement in LocloNuts, of which the'lollowing lS2LS1)9UliiCiti1i0ll,2tl1(l the accompanying drawings show the construction of the new and ii'nproved lock-nut and the proper way to use it.

1 am aware that there are many patent lock-nuts; but my object in the invention has been to so construct a nut that it shall be of greater use to the public, and my experience as a manufacturer of nuts has shown that such a nut must have the following features, all oi which are incorporated in my new invention called the Paragon lock-nut: First, the nut has a double grip, thus making certain that the nut will not shake loose; second, it has a draw-bolt strain equal to a common nut; third, it can he used either end against the work, thus being a safeguard against accident should a nut be placed on a bolt wrongyand it can also be locked on a belt or red at any place desired without either end 01'' the nut being agailist any object; fourth, it is as strong as a common nut, having the same appearance when locked, and is made standard in dimensions; lit'th, its locking device is run der full control of the operator, who canv lock or unlock the nut in an instant just when and where he pleases without the use oil. any tools other than the wrench in common use on nuts; sixth, having designed tools and method whereby the new nut can be easily made it thus becomes possible to bring it into general use, thus being of great value to the public. in order to construct such a nut, l have found it necessary to make it in two parts or sections.

' Figure 1 shows in side elevation the two parts or members of the improved lock-nut mounted on a bolt and separated from each other. Fig. 2 represents a similar view, par tially in section, of the .nut with its two members in the locked position. lFig. 3 is a perspcctivc view showing the arrangement 01? the slots and depth of the same, their number,

depth are of great value in the invention as :1.

locking device.

In Fig. 1, A represents a common three-byfive-eighths bolt. B represents that member of the nut known as the base or part designed to be placed against the work. This base is made with either a square or hexagon 'shaped exterior, as may be desired, and standard in size to [it the wrench used in screwing the nut to position. 'This ,base B has a conical-shaped projection a, which is divided into three equal parts by three slots F F F, each slot extending through one wall of the cone 0 in a direction at right angles to the bore 0]. the member and downward through the cone 0 and into the base B to a depth equal to about two-thirds the entire height oi said member. The bottom of the base l; is slightly concave in shape, as indicated by the dotted line 1), which is exaggerated in order to plainly show the idea. It is the peculiar col'istruetion 01 this member which makes this lock-nut oi great value. The member 1*] is the top oli the nut and, like the base, has an exterior of standard shape and size. This member has a bore the same size as the bore in the base, both members being tapped to lit the bolt on which they are to be used. This top member E has in one end a conical-shaped socket l-l, proportioned to the size and shape of nut desired, and each nut to lit over the eorrespomling conical projection in member 13.

To use the nut, place the member l on the bolt with the concave bottom facing the parts which are to be held. Then put on the top E, with the conical socket facing the conical projection of the member B, and screw it up until the two parts meet. Then place the wrench on the nut, covering both members and screw up ust as you would a common nut untll the work is drawn tightly together,

and then slipping the wrench off the member B onto the member E turn this member up until the nut is firmly locked. To remove the nut, place the wrench on the member E, give it a turn ofi, and then, slipping the wrench over both members, remove as you would a common nut.

The base B is of peculiar construction and works as follows: In screwing the member B against a piece of work the concave bottom acts as a lever and throws the three parts of the conical extension C (which are made by the three slots F F F) in against the threads of the bolt and gives us a good look. Now

when the member E is screwed up against the member B, the conical socket H fitting over the conical extension 0, the three parts of the cone 0 are held firmly in place, and the nut is locked still more firmly by the thrust of the socket H against the cone 0 and the similar action between the threads of the bore of the top member E and the threads of the bolt,

and there we have a double lock-nut of great CHAS. IV. GIBBS.
