BALL-BEARING GLAND FOR PACKING-NUTS.
Specification of Letters Patent.
Patented Oct. 23, 1906.
Application filed October 81, 1905. Serial No. 285,356-
St. Louis, Missouri, have invented certainnew and useful Improvements in Ball-Bearing Glands for Packing-Nuts, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to a ball-bearing gland for packing-nuts; and one of the objects of my invention is to provide a ballbearing gland for the packing-nuts that are used on gage-glasses that will readily permit the nut to be tightened, so that the packin ring of rubber or analogous material wfll tightly engage upon the gage-glass to thoroughly pack the joint and to very efficiently hold the glass in proper position.
A further object of my invention is to provide a packing-nut with a ball-bearing gland in order that said nut may be properly ti ghtened without the use of a wrench or like tool.
A further object of my invention is to so construct a ball-bearing gland as thatthe packing-ring of rubber or analogous material is forced directly against the surface of the gage-glass and is prevented from coming in contact with the screw-threads of the nut, which contact would naturally cut the packing-r ng and render it unfit for service.
To the above purposes my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully specified, pointed out in the claims, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly in sec.- tion, of a gage-glass mounted for use with my improved ball-bearing gland. in position on said gage-glass. Fig. 2 is an enlarged vertical section taken through the center of a pacl'iing-nut and showing the ball-bearing gland therein and around the lower end of a gage-glass. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2.'
Referring by numerals to the accompanying drawings, 1 1 indicate gage-valve casings of ordinary construction, which are arranged one above the other in the usual manner and connected by the gage-glass 2. These valvecasings are provided with vertically-disposed tubular members 3, which extend toward one another and in which the ends of the gage-glass 2 are located. The ends 4 of these tubular members are made perfectly flat, and adapted to screw onto said members are the tubular nuts 5, in the ends of which are provided openings 6, through which the gageglass 2 passes.
Myimproved ball-bearing glands are adapted to be positioned in the nuts 5, and each gland comprises a ring 7,, provided on its outer edge with a downwardly-pending flange 8, thus' forming an annular recess 9 in the under side of said ring. Formed in the top of the ring 7 is a groove 10, which is occupied by a series of balls 11. Formed integral with the outer edge of the top of the ring 7 is an upwardly-projecting flange 12. 13 indicates a ring which is somewhat smaller in diameter than is the ring 7, and formed in the under side of said ring 13 is a groove 14, which, together with the groove 10, forms a raceway for the balls 11. The lower end of the outer face of the ring 13 is provided with a shoulder 15, which shoulder is normally located within the upwardly-proj ecting flange 12. When the parts of the gland are assembled, the upper end of the flange 12 is bent over this shoulder 15, thus maintaining the two parts of the gland together and allowing the ring 13 to rotate freely independent of thering 7.
16 indicates a aching-ring, of rubber or analogous materia which, is referably circular in cross-section and w hich packingring is positioned around the gage-glass and rests on the flat top surface 4 of the tubular member 3 and within the annular recess 9 in the under side of the ring 7. The nut 5 is now tightened upon the exterior of the tubular member 3, and in so doing the top of said nut engages against the outer face of the ring 13, and the same turns very freely upon the balls located between said rings and the ring 7. The tightenin ofthe nut 5 naturally forces the entire gIand toward the tubu lar extension 3, and as a result the packingring will be forced against the gage-glass, as it cannot spread outwardly by reason of the downwardly-pending flange 8. The pressure is equal at all points on the packing-ring, and therefore said ring will very tightly engage against the surface of the gage-glass, and as a result a very effective packing is produced, and said gage-glass is maintained in a central osition in the o ening in the tubular memer 3. None of the metallic parts of the gland come in direct contact with the gageglass, and as the packing-ring 16 does not rotate there is no torsional strength upon the lower end of the lower one of said members,
gage-glass which would tend to fracture the glass or twist it into an incorrect position.
By the use of my improved ball-bearing glands the packing-nuts may be manipulated by the fingers to roperly tighten the packing-rings, as the bal -bearings reduce the friction between said packing-nuts and that portion of the glands that bear upon the packingrings. A gland so constructed is sim le and inexpensive, is applicable for use in a lpacking-nuts, and very effectually holds the packing-rings in proper position and prevents their being cut by coming in contact with the screw-threads of the packingnuts. The packing-rings maintain the ends of the gage-glass centrally in the tubular members 3, and as said packing-rings are pliable a universal joint is formed between the gage-glass and said packing-rings, which allows for a slight movement in any direction for the gage-glass to compensate for any variation of position of one valve-casing relative the other. The flange 8 forms a guard against the outward expansion of the rubber packing-ring, and also limits the movement of the gland toward the tubular member 3 when the nut 5 is tightened.
In practice I have demonstrated that when the gland is moved downwardly so that the lower end of the flange 8 contacts with the top surface of the tubular member 3 the rubber packing-ring will be very tightly com ressed in the annular groove 9 without brea ring the gage-glass.

7 .-In a device of the class described, a gland constructed of a pair of rings, one of which is arranged to rotate upon the other, ball-bearings arranged between the rings, there being an annular groove formed in the under side of one ring and a packing-ring arranged in said annular groove; substantially as specified.
8. In a device of the class described, the combination with a packing-nut, of a pair of rings arranged on the interior of said nut, ball-bearings arranged between said rings, there being an annular groove formed in the under side of one of said rings and a packingring arranged in the annular groove; sub stantially as specified.
9. In a device of the class described, the combination with a packing-nut, of a ballbearing gland arranged in said nut, a packing-ring arranged on the under side of the gland, and means whereby the pressure of the gland on the packing-ring is limited when the packing-nut is tightened on the gland; substantially as specified.
In testimony whereof I have signed my name to this specification in presence of two subscribing Witnesses.
