PACKING FOR RECIPRQCATING PARTS.
Specification of Letters Patent.
Patented Aug. 8, 1905.
Application filed February 1'7, 1904. Serial No. 193,954.
To all Ill/L077? it may concern:
Be it known that I, LEOPOLD KATZENs'rnIN, a citizen of the United States, and a resident of the borough of Manhattan, city, county,
, and State of New York, have invented certain new and useful Improvements in Packings for Reciprocating Parts, of which the following is a specification.
My invention relates to packings for reciprocating parts, such as piston-rods or valverods, but might also be employed for shafts or other rotary parts.
The object of my invention is to provide an efficient packing which will particularly be steam-tight.
To this end my invention consists in certain features of construction which will be hereinafter described in detail and then specifically pointed out in the appended claims.
Reference is to be had to the accompanying drawings, in which- Figure 1 is a longitudinal section of a packing arrangement embodying my invention. Figs. 2, 3, and 4c are face views with parts in section of several of the rings which constitute my improved packing. Fig. 5 is a face view of another of said rings. Fig. 6 is a detail showing a spring employed for holding the sectional packing-rings of Fig. 5 to gether. Figs. 7 to 10, inclusive, are face views of four other rings employed in my improved packing; and Figs. 11 to 14:, inclusive, are edge views corresponding to Figs. 7 to 10.
A indicates the part to which the packing is appliedfor instance, a reciprocating piston-rod.
B indicates a suitable box which may, for instance, be formed in the cylinder-head and which surrounds said piston-rod A at a distance from the rod, so as to form a chamber.
G is a stufing-box secured to the part B, for instance by means of screws D and nuts E, with a gasket F interposed between the stufling-box and the cylinder-head. A suit-.
able gland G may be provided in connection with packing H, located in a recess of the stufiing-box C. i
The parts so far described may be of any approved construction.
My invention relates more particularly to the packing which is contained "within the box or chamber B between the inner wall B of said box and the stufiing-box C, which forms the outer wall of said chamber. Im
mediately adjacent to the wall B is located a packing-ring I, as shown in Figs. 1 and 2-, which consists of two sections having a central annular rib I and connected in any suitable manneras, for instance, by means of pins I each of which has one end screwed into one of the sections of the ring I, while the other end fits loosely into a corresponding recess of the other section. Adjacent to the ring I is located another packing-ring J, also made in two sections and having a recess J for the reception of the flange I. The two sections of the ring J are pressed outwardly against the cylindrical Wall of the box B by means of the springs J located within recesses of one of the sections and pressing against the other section. Preferably the sections are overlapped in stepwise fashion, as shown in Fig. 3, so that they are guided upon each other in their expanding movement and prevent the escape of steam. It will therefore be understood that the packing-ring J will fit closely against the surrounding wall of the box B. In order to press the ring I tightly against the wall B and also to produce a correspondingly-tight joint at the opposite end of the packing, the ring J is provided with a series of sockets parallel with the axis of the part A and open toward the ring I. These sockets J 3 receive coiled springs J which engage the flange portion of the ring I exteriorly of its annular rib I. Adjacent to the ring J is provided another expanding ring K, (see Fig.
4,) which is made in two sections overlapping in step fashion and pressed apart and into firm contact with the surrounding wall of the chamber B by means of springs K, similar in arrangement and function to the springs J While the rings J and Kform a tight joint at their outer peripheries, but do not closely hug the part A, the reverse condition obtains with the rings L, M, N, N, and P, which I will now describe.
The rings L, M, and P are of like construction, as shown in Figs. 1, 5, and 6. Each of these rings consists of three sectionsthe meeting lines of which are disposed tangentially to the inner surface of the ring. Each of these rings has a groove in its periphery to receive the, spring Q, which presses the ringsections against the reciprocating rod'or other part A. The rings L and M, which are adjacent to each other, are so placed that their joints are staggered. (See Figs. 1 and 5.) Pins L may extend from one of these rings to the other toprevent the rings from shifting circumferentially in relation to each other and maintain them in break-joint arrangement. The ends of the springs Q are con nected by means of hooks R, each of which has a head R within the coiled end of the spring, and for the purpose of holding the said head in position the end coils of the spring are of reduced diameter. It will be understood that the springs Q hold the rings L, M, and P tightly against the piston-rod A.
The two rings N N are of the form shown in Figs. 8 and 12 and comprise two sections which are not connected with each other in any manner, but are set loosely in the ring 0, (shown in Figs. 7 and 11,) the rings N N being tapered toward each other and the ring 0 having a recess which flares from the center toward both ends. The outer portion of the ring 0 has four small recesses 0, through which screws 0 may be inserted for connecting the sections of the said ring and pressing the rings N N tightly against the part A.
Adjacent to the ring P is provided the ring S, consisting of two sections connected by screws S and of a diameter to leave a small clearance around the reciprocating or other.
part A. The end surface of the ring S which faces away from the ring P is convexed spherically. The adjacent end ring T, Figs. 10 and 14:, has a correspondingly-concaved recess and is also of sufficient diameter to allow of some play. The sections of this ring overlap in interlocking fashion, so as to prevent said sections from spreading apart.
It will be seen that the ring b allows for some lateral motion or play of the rod A.
The piston-rod. A is hugged tightly by the What I claim for my invention, and desire to secure by Letters Patent, is
1. In a packing for moving parts of machinery, a box surrounding the moving part at a distance but out of contact therewith, packing-rings surrounding the moving part within said box, means for pressing one of said rings against the moving part, springs for pressing another ring against the surrounding wall of the box, and means for pressing the rings lengthwise of the moving part, against the ends of the box.
2. In a packing for moving parts of machinery, a box surrounding the moving part at a distance but out of contact therewith, and packing-rings surrounding the moving part within said box, said rings comprising a contractile ring havingarecessed periphery, a coiled spring surrounding said ring and situated within the recess thereof, the ends of the spring being tapered, and hooks each having one end in engagement with the other hook and the other end within the spring, at its tapered portion.
3. In a packing for moving parts of machinery, a box surrounding the moving part at a distance but out of contact therewith, contractile packing-rings surrounding the moving part within the box and engaging said part tightly, expansive packing-rings likewise surrounding said moving part within the box, means for-pressing said expansive rings against the surrounding wall of the box, and means for pressing the rings lengthwise of the moving part against the ends of the box.
4. In a packing for moving parts of machinery, a divided packing-ring surrounding the moving part, a spring surrounding said divided packing-ring, and hooks separate from said spring and having one end in engagement with said spring and the other ends in engagement with each other.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
LEOPOLD KATZENSTEIN.
