To alZwk-om it may concern:

Be it known that I, CHAUNCEY E. ASH- LEY, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Locking Sockets, of which the following is a specification.

'My present invention relates to locking means for a plurality of bolts or nuts, and more particularly to locking sockets adapted to embrace the bolt heads or nuts and for cooperation with a wire to retain the bolts or nuts against rotation incident to vibration or other casual forces coming thereupon which might otherwise cause them to loosen.

It is now common practice to lock a series or a plurality of bolts against rotation after they have been adjusted or turned tight by means of a wire drawn through holes extending transversely through the heads of the bolts the wires being secured to the end bolts of the series, or to some rigid elements adjacent the end bolts. In order to accomplish this the holes must first be drilled through the bolt heads before they are positioned. It is also necessary to drill a plurality of holes transversely through each bolt head these holes opening at opposite wrench faces of the head. This is done in order that, when the bolts are adjusted in place the wire may be drawn through the particular hole of each bolt head that is alined with the holes of adjacent bolts, or those which are closest to alining so that sharp bends in the wire will be avoided. It has been found expensive to drill these holes especially in bolts having hexagonal or octagonal heads since, after one hole has been drilled, the drill used in making the next hole is very apt to break when striking the wall of the first hole at an acute angle.

One of the principal objects of my invention is therefore to provide, as an article of manufacture, a locking socket which may be used with standard bolts having polygonal heads, or standard nuts wit-bout machine work thereon and using a wire in the manner similar to that above set forth.

Another object of my invention is to provide lockin sockets for association with standard b0 ts or nuts and which are so shaped or formed that a socket wrench which is most frequently used in rotating such bolts or nuts, may also be used without interference in turning the bolt or nut tight or otherwise adjusting it.

A further object of my invention is to provide as an article of manufacture, a lockmg socket which is inexpensive to manufacture and neat in appearance which requires no bending of portions in order to accomplish the locking arrangement and which may be devoid of points or rough edges which are characteristic of many bolt and nut locks heretofore patented and in use.

Other objects and advantages of the in vention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawmgs:

Figure 1 is a view partly in elevation and partly in section showing a tap bolt e uipped with a locking socket formed according to my invention, the socket being shown in elevation.

Fig. 2 is a similar view, the socket being shown in vertical section.

Fig. 3 is av plan view showing a plurality of bolts locked against rotation by use of locking sockets formed according to my invention.

Fig. 4. is a view similar to Fig. 2 showing a socket wrench in position for turning of the bolt.

Fig. 5 is a view partly in elevation and partly in section showing a plurality of nuts locked against rotation on stud bolts, sockets, according to my invention, being used in connection therewith.

Fig. 6 is a fragmentary plan view showing one of the nuts and associate stud bolt of Fig. 5 with the locking socket and wire in place.

In the drawings, where similar characters refer to similar parts throughout the several views, A designates generally a polygonal member, such as'the head of a bolt B, or a nut in screw threaded engagement with a bolt, such as stud bolt C; D and E elements receiving the bolts B and C; F locking socket constructed or formed according to my invention; G a socket wrench; and H a wire associated with the socket F.

With reference more particularly to, Figs. 1, 2 and 3 of the drawings, where the Invention is shown as applied to tap bolts B, the bolts are there shown as provided with inc the wire H as turned upon itself and twist- 7 which engages the under side of. the bolt head A, and in the example shown is provided with a concentric perforation 8 for the reception of the stem of the bolt. Extending from this base 7 is a side wall inclosure toembrace and extend beyond the wrench faces 9 of the bolt head, this wall being designated generally by character 10. It forms a socket 11 for the reception of the bolt head. It is referred to form this side wall inclosure integral with base 7, shaped to, engaging and extending beyond the wrench faces of a standard bolt head, or nut. Those portions of the wall 10 opposite to base 7, or in other words, those portions of the wall extendin beyond the bolt head or nut are provided with transverse perforations 12 for the reception of the wires H in a manner to be subsequently set forth. It is preferred to round off the upper portion of the locking socket as indicated at 13 so asto provide no points WhlCh are likely to injure flesh.

In the production of these locking sockets, as by drawing or die stamping t e side wall inclosure is made of a thickness to successfully withstand the compressive and torsional stresses coming thereupon incident to the use of a wrench used in turnin the bolt into place. As clearly shown in ig. 4 of the drawings, an ordinary socket wrench ma be used without interference. The side wal inclosure may be of such a thickness that the next size socket wrench to that which would be used for turning the bolt or nut into place, may be used, when the bolt head or nut is equipped with a locking socket.

A number of perforations 12 are provided in order that the wire H may be drawn through the perforations of adjacent locking sockets, which perforations either aline, or are closest to alining, so that sharp-turns in the Wire will not e necessarv. In this connection, reference is had to Fig. 3 of the drawing, in which it is to be assumed that the bolt B is turned clockwise in order to cause binding engagement between elements D and E. The wire H is therefore trained through the perforations 12 of each locking socket which are closest to alining, and in a manner that should there be a tendency to rotate either of the bolts in a contra clockwise direction, such will have a tendency to turn the next adjacent bolt tighter in engagement, with the member E. While I have shown hexagonal heads A. Such bolts are frequently used for the purpose of securing the head to the main body portion of a cylinder, which parts may be designated by characters E and D,respectively.

The locking socket is preferably formed of a single piece of metal to provide a base ed about that section 14 between the locking sockets, as indicated at 15, it is to be understood that the terminals of this wire may be secured to any rigid element or elements available and that a series of bolts may thus be secured against rotation, due to vibration, or casual forces coming thereupon.

In Figs. 5 and 6, the locking sockets are shown engaging polygonal nuts which are turned upon studbolts C, which are frequently used in securing the cylinder head to cylinder block. The use of the locking socket is similar hereinbefore described, in that the bolt C extends through the perforation or aperture 8 in the base 7. The wire H is, however, trained about the circumference of the bolt C, as indicated at 16 where the bolt extends a considerable distance above the nut A.

It is to be noted that an ordinary socket wrench may also be used in turning nuts tight, or a j nection it is pointed out that quick assembly and dismembering of machinery is often desirable and that the lockin sockets are so formed that ordinary too 5, such as monkey wrenches, or socket wrenches,

usting them and in which conmay be used, without interference, and the locking socket capable of remaining in good condition under the action of the wrenches in turning or loosening bolts or nuts.
