Speccaton of Letters Patent.
Patented Jan. 17, i911.
Serial No. 539,194.
To all 'whom it may concern:
Be it known that I, SYLvANUs PALMATEER, a citizen of the United States, residing at Staples, in the county ot Todd and State of Minnesota, have invented a new and useful Nut-Lock, of which the following is a specification.
My invention relates to nut-locks; and the object is to provide an improved, eliicient and comparatively cheap means y which a nut will be prevented from accidental loosening and separation from the bolt, and yet the nut may be removed when so desired.
ln the accompanying drawing ;-Figure l is an edge view of two fiat pieces of either wood or metal with a bolt passed through them and provided with a nut and my novel locking means applied thereto and shown partly in section as on the lines a-ri and -Z) in Fig. Q; also a key for the device is shown to the lett in Fig. l. Fig. '2 is a rear view of the locking device, which involves two plates A and B, ot' which plate B is partly broken away in Fig. Fig. 3 is a face view ot the side otl plate A against which the nut is placed, showing the locking catch projecting through it. Fig. i is a rear side view et the nut, showing the tace ot it. tl at goes against the hacking device. 5 is a lett hand edge view ot the plate A in Fig. 1.
Referring to the d lawing by letters of rei:- erence7 EL and B designate two preferably square plates, each provided with a central hole C for a bolt l) to pass through after it is passed through the parts that are to be bolted together, which in Fig. l are represented as two iiat iron bars E and F. The bolt is in said view shown as having a round head G and a key rib H to engage a suitable notch in the bar E and thus prevent turning ot' the bolt when it is inserted, and the threaded portion is provided with a nut N having in its clamping tace a circular row ot indentures l). The plates A and B of the complete locking device are secured together by two rivets J, J, whose heads K are pointed and hardened and project slightly beyond the face ot the rear plate. Before the plates are riveted together plate A is provided with an aperture L through which project forwardly on a slant the longestmember of a T-shaped dog M, which is placed in a T-shaped groove Q in the rear side of the plate, where it is pressed into engagement with the indentures of the nut by a fiat curved spring S, which is retained in a groove R in the plate and has a T-shaped end resting in the T-shaped end por 'lion olf thel groove R. lVhen the plates are assembled the rear plate B presses upon the arched middle portion of the spring and thus give tension to the latter against the dog, so that the latter will normally project through aperture L and engage the indentures or cavities l? in the nut when the latter is screwed into operative closeness to the plate A. Said plate A is provided in one edge with a duct or hole U, which extends into the groove Q at the front side vof the dog M. In Fig'. l, V designates a pointed tool or hey, which may be inserted in said hole U and by pushing it against the dog the latter may be disengaged from the nut when it is desired to remove the nut, and until the key is thus applied the nut is safely locked by the dog.
In applying` the device upon wood worlr the nut N will readily torce the heads l into the wood and thus prevent turning ot the locking dcvice,.but it applied to iron a light blow should be given either on the outer plate or on the nut N to cause the heads K to sink sullieiently into the nietal to prevent turning ot the device on the bolt. l'llhere these heads K are employed the plates may be round or of any other desired torni; and if the device is applied to rail joints or other structure where flanges or other obstruction to rotation of the plates is present, the rear plate is made square or oblong and of a size to engage such obstructions, and the pointed heads K may in such cases be dispensed with.
To facilitate the opening of the lock by the key V, the latter has its front end bev eled at N on one side and its other end formed with a ring X, so that even if the dog M is stuck, a turning movement of the key after its bevel lV is pushed against the dog, will cause the unbeveled side ot the key end to act as a cam and torce the dog out ot' engagement.
lWhat I claim is l. In a nut-lock, the combination with the threaded end of a bolt, of a nut having a circular row of indentures in its rear side, a primary washer plate on the bolt near the rear side of the nut and having in its front side an aperture and in its rear side loosely embedded a dog and a spring pressing on the dog to hold it normally projected through the aperture and engaged With the indentures in the nut, a secondary plate secured to the rear side of the primary plate to retain the dog and its spring in place and give tension to the spring; said primary plate having in one edge a hole extending to the front side of the dog, and a key insertible into said hole for disengaging the dog from the nut.
2. In a nut-lock, the combination with the threaded end of a bolt, of a nut having a eircular roiv of indentures in its rear side, a primary Washer plate on the bolt nearjthe rear side of the nut and having in its front side an aperture and in its rear side loosely embedded a dog and a spring pressing on the dog to hold it normally projected through the aperture and engaged with the indentures in t-he nut, a secondary` plate secured to the rear side of the primary plate to retain the dog and its spring in place and give tension to the spring, said primary plate having in one edge a hole extending to the front side of the dog, and a key insertible into said hole for disengaging the dog from the nut; said secondary or rear plate having at its rear side sharp studs adapted for engagement With the structure to which the bolt is applied to prevent accidental turning of the plates.
3. In a nut-lock, the combination with the threaded end of a bolt, of a nut having a circular row of indentures in its rear side, a primary Washer plate on the bolt near the rear side of the nut and having in its front side an aperture and in its rear side loosely embedded a dog and a spring pressing on the dog to hold it normally projected through the aperture and engaged with the indentures in the nut, a secondary plate secured to the rear side of the primary plate to retain the dog and its spring in place and give tension to the spring, said primary plate having in one edge a hole extending to the front side of the dog, and a key insertible into said hole for disengaging the dog from the nut; said plates being secured together by rivets, the heads of which are at the rear side of the rear plate and are formed into sharp studs adapted to take hold of the structure to which the bolt is applied, and thus prevent accidental turning of the plate.
4. In a nut-lock, the combination with the threaded end of a bolt, of a nut having a circular row of indentures in its rear side, a primary Washer plate on the bolt near the rear side of the nut and having in itsfront side an aperture and in its rear side loosely embedded a dog and aspringl pressing on the dog to hold it normally projected through the aperture and engaged with the indentures in the nut, a secondary plate secured to the rear side of the primary plate to retain the dog and its spring in place and give tension to the spring, said primary plate having in one edge a hole extending to the front side of the dog, and a key insertible into said hole for disengaging the dog from the nut; said plates being secured together by rivets, the heads of Which are at the rear side of the rear plate and are formed into sharp studs adapted to take hold of the structure to which the bolt is applied, and thus prevent accidental turning of the plate; said bolt having a head and means adjacent the head to prevent rotation of the bolt when it is inserted for use.
