AUTOMATIC COUPLING FOR STEAM. AIR. OR OTHER PIPES OF RAILWAYTCARS.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed October 5, 1904. Serial No. 227,213.

To ctZZ whom it may concern:

Be it known thatI, FRANK F. LIPPs, a citizen of the United States of America, and'a resident of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Automatic Couplings for Steam, Air, or other Pipes of Railway-Cars, of which the following is a full, clear, and exact description.

This invention relates to automatic couplings for the steam and air pipes of railwaycars of the general character shown and described in Letters Patent of the United States granted to me April 7, 1903, No. 724,720.

The object of the invention is to produce couplings for the longitudinally-ranging pipes of the cars of the simplest possible character and construction with correspondingly increased capability for reliable action and lesscned liability to derangement.

Another object is to so construct the pipecoupler heads and their bars and conjoint appurtenances as to make it practicable and entirely satisfactory to bodily carry the pipecouplings in suspension by and closely under the car-couplings and draw-bars of the description now in most common use and without in any way reconstructing or encumbering the car-couplings.

A further object is to make the pipe-coupling heads of a form and construction which is practicable, of cheap and easy manufacture and great durability, and with provision for the retention, removal, and replacement of annular externally-flanged fittings which constitute the orifices of the steam and air conduits and which in the coupling come together with and remain in more or less compression.

A further object is to construct a pipe-coupling head having a central or body portion which has no wearfor instance, of cast-iron and to make a portion surrounding the body and which is equipped with the projections or horns for causing one of the pipe-coupling heads to be longitudinally alined with another similar head of a good-wearing metal such, for instance, as a forging or a malleableiron casting.

The invention consists in the combination and arrangement of parts and the construction of certain of the parts, all substantially as hereinafter fully described, and set forth in the claims.

The improved couplings for the steam and air pipes of railway-cars are illustrated in the accompanying drawings, in which- Figure 1 is a side elevation showing the couplings for the pipes in coupled relations and in their arrangement relatively to the carplatforms and the draw-bars and couplings of adjoined cars. Fig. 2 is a front end elevation of one of the pipe-couplingsthat is, as seen beyond the line 2 2, Fig. 1. Fig. 3' is a plan view of one of the pipe-couplings. Fig. 4 isa central longitudinal sectional view of one of the pipe-coupling heads. Fig. 5 is a perspective view of an appliance pertaining to the improved pipe-coupling. and which is for removable attachment on the car-coupling draw-bar. Fig. 6 is a perspective view of a nectionally-made portion of the pipe-coupling iead.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A A represent the platform portion of steam-railway cars, of which B B are the car-couplings carried at the ends of the draw-bars C C, and s a a represent a plurality of rigid pipes understood as carried and ranging longitudinally under the carbody, the ones $3, for instance, being the steampipes, while the ones a a are the pipes for the conveyance of air used for operating the airbrakes and the whistle.

D D represent the automatic pipe-couplings, which are made counterparts one of another for the ends of the cars. Each pipecoupling comprises a head 6 and a horizontal longitudinally-extending body or bar 6 the head or bar, or both, having forwardly-opening fluid-passages a a and s s therethrough, coupled into which are pipe-sections c a and 8 which as to the whole or portions of their length are of flexible character, and these sections are connected with the ends of the fluidpipes of the car which terminate in the rear of the car-couplers.

The pipe-coupling body has at its rear end an eyebolt d, afiixed by the nut (Z and connection of the eyebolt (Z is made with an eyebolt f, which by nut f is affixed in the position shown to the lower end of the bar-spring g, which is carried as a depending equipment of the car body, and preferably, strictly speaking, as an appliance to the car-coupling draw-bar C, and the coupling-body is therefore at its rear or inner end supported in such a manner that it may move substantially bodily in unison with the draw-bar, maintained always at the same level, and be capable of a transverse swinging movement on a horizontal plane from the joint or shackled connection at the interlocking point of the cycbolts as the center of motion.

The pipe-coupling is forwardly supported by having its head formed with an upwardlyextended eye-lug h, in which is engaged a link of a short heavy chain '2', while the upper link or eye of the chain has a shiftable or transversely-running engagement with a runner rod or member 7', which, as shown in the plan view Fig. 3, is of arc form, with its general direction transversely of and-under the car-platform, and the said runner memberj forms the-lower portion of a frame, the uprights 7' 7' of which have connection, as shown, at and with the under side of the car-platform.

As specifically shown, the appliance provided to the draw-bar for supporting the depending bar-spring is in the form of a clip, comprising the saddle-block 7c, the strap Z, and the under block m, having the vertically-perforated ear-lugs 1a, through which the screw: threaded extremities of the strap pass, the strap extremities receiving thereon below the ear-lugs the supporting and confining nuts m and the under block is made with a downwardly-opening recess in which is fitted and secured by a cross pin or bolt 0 the upper end portion of the bar-spring g.

It will be appreciated that the pipe-coupling may have motions fore and aft in unison with the car-coupling and also more or less fore-and-aft motion independently of the motion of the car-coupling, the longitudinal mo- 'tion in the rearward direction being permitted by the flexible connection and sup port for the forward portion of the pipecoupling, and such longitudinal movement as the pipe-coupling has independently of the car-coupler can be against or with-the reaction of the bar-spring. The horizontal transverse motion which the pipe-coupling has imparted thereto by the horns m 00, having the form and arrangement and manner of operation substantially as described in my aforementioned patent to bring the pair of heads into proper alinement for the register of the forwardly-open fluid-passages therethrough, is permitted by the capabilities for such end found in the forward support of the charac: ter described and as shown for the coupler.

As preferably constructed the head and body of the pipe-couplers are made of cast-iron, with the passages therethrough, as shown and described, the head being in the design shown cross-sectionally rectangular, and the further section or portion is separately made, advantageously as a forging malleable-iron casting or other wear-withstanding metal inthe form of a frame t with the horns an integral there with, this frame-like section being shrunk onto the head and additionally secured by crossbolts or keys.

After protracted use in case the horns may become broken or badly battered the shrunkon section may be removed and replaced by new ones and of course without the necessity of discarding the entire heads.

The forwardly-opening passages in the pipecoupling heads have, as represented in Fig. 4, circularly-rabbeted orifices o, in which annular externally-flanged fittings w are located with the flanges sunk within the orifices and having their unfianged portions protruding beyond the plane of the front face of the coupler-head, and ring-nuts y are screw-engaged into the rabbeted orifices and confine the flanges of said fitting against the seats therefor.

As fittings or packings for the orifices of the air-passages compressible rubber may be the preferred material, but for the terminals of the steam-passages a metal, such as soft brass, is preferably used.

At times when the pipe-coupling is not to be in a coupled relation with a similar pipecoupling of an adjoining car the coupler-head and body 5 may be swung considerably transversely, so that the head and horns are disposed in an outof-the-way position closely under the steps at the side of the car-platform.

Seated, as shown, in the rabbeted orifice of any or all of the forwardly-opening fluid-passages through the pipe-coupling head is a disk of gauze .2 to intercept any dirt or dust which may come thereto through the steam and air pipe of the car, and when the packings are removed or replaced these gauze-sections may be temporarily removed. for clearing out any accumulations which may be found at the rear thereof.
