THREAD PROTECTOR NUTS Filed May 2, 1941 Patented Mar. 16, 1943 THREAD PROTECTOR NUTS Woodford Cox, Harrisburg, Ill. Application May 2, 1941, Serial No. 391,575
1 Claim.
This invention relates to a. clamping nut device particularly adaptablev for use with a threaded terminal stud or' post of an electric apparatus, and it is the principal object of this invention to provide a pairof clamping nuts designed to clamp therebetween a cable terminal may be made within the scope of what is claimed without departing from the spirit of the invention.
A practical embodiment of the invention is illustrated in the accompanying drawing, where- Figure 1 is a sectional view showing a pair of thread protector nuts with a cable terminal clamped therebetween.
Figure 2 is a transverse horizontal sectional view on line 2-2, Fig. 1, showing the cable terminal seated on face of lower nut.
Figure 3 is a plan view' of the upper nut. Referring to the drawing in detail, l denotes a threaded stud or post such as may be used on a battery, switchboard or other electrical apparatus, and to which the cable terminal H is to be connected. The cable terminal is of a well known type comprising a tubular shank portion l2 in which the end of an electric con-v ductor cable I3 is securely connected, and a flat extension or clamping end |4 provided with an elongated opening l5. While a cable terminal has been shown by way of example, it is to be understood that the clamping nuts to be hereinafter described maybe used with a conductor bar or any other type of perforate electrical connecting member. In fact as will be obvious from the following description the pair of clamping nuts may be used on any threaded member where it is desired to protect the threads thereof from example, of hexagonal form. Both the boss 2|. and head 22 are co-axially disposed on each side of the circular flange, there extending through the same a threaded bore 23. Preferably the upperface 24 of the circular flange is machined to provide a flat surface, and the boss 2| is also machined to an external diameter such as to permit the same to flt into the opening I! of the cable terminal II with the clamping end i4 thereof thus in seating engagement with the flat face 24.
The upper nut I9 is shaped to provide a circular flange 26 of substantially the same dimensions as the flange 20 on the lower nut l8, and the underside face 21 of the flange'26 is likewise machined to provide a flat clamping surface. Above the flange 26 the nut I9 is provided with an hexagonal wrench engaging head 28, and extending into the flange 26 co-axial with the head 28 is a circular recess 29 of a diameter slightly exceeding the external diameter of the circular boss 2| on the lower nut i8, and of a depth such as to permit the reception therein of the upper portion of said circular boss 2|. Extending axially through the nut I9 is a threaded bore 3|! of the same dimensions and number of threads as to size as that of the threaded bore 23.
Thus, it will be seen that by first placing the lower nut ill on the stud l0, then placing the flat extension l4 of the cable terminal II on theface 24 of the nut |8 with the boss 2| projecting up through the opening IS in said flat extension, and then placing the upper nut I! on the stud i0, that by setting up the nuts l8 and I! on the stud ill the cable terminal II will be clamped between the clamping faces 24 and 21. As the cylindrical boss 2| projects into the cylindrical recess 29 it is apparent that the boss 2| thus acts as a guard for the threads of the stud I0 so that the same can never be marred or otherwise injured by the cable terminal II.
This clamping nut construction will permit axial adjustment of the cable terminal ii on the stud Ill at any point thereon in the manner readily apparent.
vIn some instances it may be desirable to attach small conductor wires to the stud I0, as for example an ammeter wire conductor to an ammeter. Accordingly the flanges 20 and 28,
respectively of the nuts I8 and iii, are provided with inwardly extending radial openings 22, there being four such provided on each flange. Arranged normal to the axis of each opening 32 and projecting from the flange on the same contact faces, a cylindrical annular boss integral with one nut and projecting axially beyond the flat contact face thereof, the other nut having an annular recess extended inwardly of the flat contact face of the nut, said annular boss being complemental to the recess and of less diameter than the recess so as to provide a free fit whereby said contact faces may be brought into contacting engagement with an interposed terminal con- 10 nector engaged upon said boss.
WOODFORD cox.
