UNITED STATES PATENT JOHN J. FARRELL, 0F LAWRENCE, MASSACHUSETTS, ASSIGNOB TO A. M. FARRELL, 0F PHILADELPHIA, PENNSYLVANIA.
NUT LOCK.
Application filed May 14,1921. Serial No. 469,610.
To all whom it may concern:
Be it known that I, JOHN J. FARRELL, a citizen of the United States, residing at Lawrence, in the county of Essex, State of have invented certain new and useful Improvements in Nut Locks, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to nut locks of the type in which a locking tongue carried by a washer extending around the bolt is forced into contact with the nut to prevent it from rotating,
is simple and inexpensive in construction, adapted to be formed from a single piece of sheet metal, adapted to be readily applied, and will hold the nut positively against rotation, and at the same time maybe readily caused to release the nut.
With the above described objects and other objects hereinafter described in view my invention consists in the construction and combination of elements hereinafter described and claimed.
In the drawings,
Figure 1 is a top plan view of a washer embodying my invention as it appears when cut from a piece of sheet metal,
Figure 2 is a longitudinal central sectional view of the same with the locking tongue bent up,
Figure 3 is a side view of the washer in place on a nut, the locking tongue being bent up as shown in Figure 2 so as to permit the nut to be turned to its seat,
Figure 4 is a view similar to Figure 3 but showing the locking tongue driven down into the material through which the bolt extends and bearing against a side face of the nut,
Figure 5 is a top plan view of the con struction shown in Figure 4:,
Fi ure 6 is a view similar to Figure 4 but showing the point of the locking tongue curled back under the body of the tongue, and
Figure 7 shows a longitudinal central sectional view of a washer having its end in rear of the locking tongue turned down to engage the bar or beam through which the bolt extends.
In the drawings 1 indicates a washer adapted to be stamped or cut from sheet metal at a single operation, having an open-' and my invention has for its object to provide a nut lock of this type which ing 2 for the bolt to pass through, and having formed therein a lockingtongue of arrow head shape the point a of which extends within the line of the opening 2 this open ing being, except for this point of the lock-"- ing tongue, circular.
The locking tongue 3 is, after being formed as described, bent upward from its base with its point t bent downward, some what in the form of an inverted V as shown in Figure 2, so as to leave between the base and the point an upwardly extending angle 5. The device is then ready for use.
The washer is, in use, placed. with its opening 2 about the bolt 6, the body of the washer resting on the face of the bar or beam through which the bolt extends, the locking tongue by reason of its being bent upward as shown, bein out of the wayof the angles between the sice faces of the nut 7 so that the nut can be turned freely. 'The nut is then turned on the bolt 6 until it can be turned no further and the locking tongue is then, by a blow of a hammer, or the wrench used to turn the nut to place, on the angle 5 driven down. This forces the point 4% downward into the material through which the bolt extends, if the material is wood which the point can enter, as shown in Figure 4:, or is caused to curl under the body of the tongue if the material through which the bolt extends is too hard to permit the point to enter it. The blow on the angle 5 also, by forcing the body of the locking tongue downward, forces its forward end into contact with a side face of the nut and thus prevents it from turning independently of the washer. If the point 4 enters the material through which the bolt extends it will serve to lock the washer against rotation. If the point 4: does not enter the material a screw or pin 8 extending through an opening 9 in the base or lobe portion of the washer may be used. A screw or pin 8? may be used at 9 also when the point a enters the material as an additional means for preventing movement of the washer as well as serving as a means for holding the locking tongue against being bent upwards.
If desired the washer may be provided at its end near the base of the locking tongue with a downturned portion 10 to be driven into the material through which the bolt extends or may extend over the edge of the bar or beam.
In order to release the nut it is only necessary to insert the end of a screwdriver or the point of any sharp pointed instrument beneath the angle 5 of the locking tongue and lift it.
Having thus described my invention what I claim is;
l. In a nut look, a washer having an opening through it for the bolt and having formed integral with it a locking tongue so formed that its point extends within the line of the opening as formed, having its base portion bent upward and its point bent downward so that its point will be sufficient ly out of the way of the nut to permit it to he turned.
2. In a nut look, a washer having an opening through it for the bolt and having integral with it a locking tongue so formed that its point-extends within the line of the openingas formed, having its base portion bent upward and its point bent downward so that its point will be suriiciently out of the.
the way of the nut to permit it to be turned, the locking tongue being adapted to be driven down to contact with a side ttace of the nut, and means for preventing the washer rroin turning relatively to the material through which the bolt extends.
a. In a nut look a washer having an opening through it for the bolt and having integral with it a locking tongue so formed that its point extends within the line of the opening as formed, having its base portion bent upward and its point bent downward so that its point will be sufficiently out'of the way of the nut to permit it to beturned, the locking tongue being adapted to be driven down to Contact with a side face of the nut; the looking tongue being provided with an opening in its base for a screw or pin.
5. In a lock nut, a washer having an opening through it for the bolt and having formed integral with it a pointed locking tongue so formed that its point extends within the line of the opening as formed, having its base portion bent upward and its point bent downward so that its point will be suitiiciently out of the way of the nut to permit it to be turned the point being adapted to be driven into the material through which the bolt extends and to serve to prevent rotation of the washer.
In testimony whereof I affix my signature this twentyninth day of January 1921.
. JOHN J. FARRELL.
