Owing to the parts being built exceptionally heavy to meet extreme conditions, and the novel and peculiar design of the segmental ring to over- come the objéctionable features found in ordinary metallic packings, the company claims the following advantages: The. packing is composed of few parts--only enough-to pro- vide for every condition of service. Any engineer or me- chanic of ordinary judgment can apply the packing, and after first application the parts are permanent fixtures; no disconnecting of rod is necessary for the renewal of the packing ring. The ball joint surfaces on packing ring, the sliding joint between cup and gland and the clearance of cup in bore of box or gland, provide for all irregularities of L. FiG,. 1. A.A.---VIBRATING CUPS.

Owing to the construction of the segmental packing ring, it cannot be unduly forced on to the rod by the pressure and friction and wear are thus reduced to a minimum. As wear of rod is so slight, no truing up of 'rods is necessary for a number of years. The only renewal necessary is the packing ring, which is-the only part in contact with the rod. Rod is not worn oval or tapered, and after years of service, the renewal of packing ring will pack the old rod as effectively as the first application. Adapta- bility: The Hayden metallic packing can be applied to any stuffing-box that may havé been designed for soft packing, or any other metallic packing without change to stuffing-box. The company represents that it has had packing run for years without the slightest repairs, on engines running almost continuously, and the stopping of an engine and the conse- quent loss of time to repair the Hayden packing is a thing unknown. The Segmental Packing Ring is made of composition metal, and is an alloy which will withstand the extremely high temperatures, such as are now common, without melting or breaking. The ring is made up of three seg- ments, and is held between the vibrating cup and follow- er by contact on the ball joint surfaces; these surfaces are at such an angle to the rod, that the compression of the spring and pressure, are such as to allow a gentle bearing on rod, and: no excessive wedging on the rod can take place. The angles on ends! of segments are such that } d 1 4 a PIG. 3; SEGMENTAL RING INTERIOR VIEW. , SEGMENTAL RING ASSEMBLED END VIEW. _the ring feeds to the rod slowly, taking up the slight wear of the ring, and friction is thus reduced to a minimum. As segments come together at ends and form practically a solid ring, the ring does not squeeze out between the vi- brating cup and rod, nor score or wear the rod out of true; neither vibration, oscillation, or out of line move- ment of the rod puts any undue strain on the packing, and the packing is free to travel with rod and keep in perfect contact with it. As a result, friction is reduced to a minimum. : oe : Fig. No. 1 illustrates the Hayden metallic packing, sin- gle tvpe, and is especially suitable for horizontal piston rods and valve stems of steam engines, pumps, compress- Ors, etc. Fig. No. 2 illustrates the Hayden metallic packing, double type. This tvpe of packing consists of two distinct sets of packing, separated by a wall ring, and is used particularly on vertical roads. On vertical rods with single packing, there is more or less condensation dragged out along the rod, as the stuffing box acts as a pocket to catch condensation from the cylinder. The second or lower set of packing catches this condensation, and is drawn off by means of a connection shown at bottom of gland. The second set of packing also is an aaditional precaution in case the first wears out. The connection at bottom of gland is also used as a lubricator connection and the space between the two sets of rings can be partially filled with oil with a pump, and the rod travels in a bath of oil, making this a perfect method of lubrication.
