ENGINE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 570,672, dated November 3, 1896.

Application filed June 6, 1896. Serial No. 594,579. (No model.)

To all whom it mag concern:

Be it known that I, J OHN MAcKENzIE, a resident of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Engine- Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in devices for attaching car-couplin gs to the pilot ends of engines, the object being to provide means for attaching the well-known and standard makes of couplings to the front sill of the engine in a solid and substantial manner, the construction of parts being such that the entire draw-bar and coupling-head can be removed for repair or replacement within a short space of time and without the aid of tOOlSOlillBI' than an ordinary wrench.

\Vith this object in View my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view showing my improvement applied to the pilot of a locomotive. Fig. 2 is a view in plan of the same. Fig. 3 is a top plan view of the lower section of the casing. Fig. 4 is a similar view of the top section of the casing, and Fig. 5 is a view in front elevation of the casing.

A represents the front sill of an engine, to the front face of which is secured the twopart casing B, which latter is adapted to receive and retain the draw-bar of the coupling. This casing is composed of an upper section A and a lower section A the upper section constituting the major portion of the casin g, while the lower section constitutes the bottom and a small portion of the sides thereof.

The rear end of the upper section A of the casing A is enlarged at its base or rear end, the enlargement being in the form of a flange which projects laterally and vertically, con stituting a seat which rest-s solidly against the front sill of the engine. The upper end of this flange or base is continued rearwardly in ahorizontal plane, so as to rest on the top of the sill, and the flanges and body ofthe section A are strengthened by the rib A which extends throughout the length of the section and is cast integral therewith. The upper section is also provided at its sides, near its front or outer ends, with the cylindrical pockets 0, which form seats for spiral springs O, employed for yieldingly holding the draw bar and coupling head centrally within the casing.

The lower section A as before stated, constitutes the bottom and a portion of the sides of the casing, and its rear end, like the end of section A, is enlarged laterally to afford a firm and solid base and is also provided with a horizontally-projecting flange d, which rests under the sill, the rear end of the flange being provided with an upwardly-projecting lip, which rests in a slot or kerf in the under face of the sill.

The upper section A of the casing is secured to the sill by the bolts 6, which pass through the lateral flanges and horizontally through the sill, and hence secure the upper section in place independently of the fastening devices which secure the lower section A in place. In addition to these bolts (2 the section A is also secured by the bolts e, which pass vertically through'the top flange of the section A, through the sill, and through the horizontal flange of the lower section. By means of the bolts 6, however, the upper section of the casing can be secured in place independently of the lower section, and hence can be permanently fastened in place before placing the draw-bar in position.

- In addition to the bolts e and e, which secure the two sections together and to the sill, the two sections are further united by the bolts 6 6 which pass; through flanges e integral with the sections.

With this construction it will be seen that by securing the upper section of the casing in place andtlieir placing'theclraw-bar inp0 sition with one shoulder f thereof against the shoulder f of the casing the draw-bar canbe locked in place by simply securing the lower section in position, as 13'efore explained .and wlien se assembled the couplingrests in front and clearoftliez-front end of the casing.

The casing, is supported at its outerend against vertical movement bythe support G, which latterr'ests at. its lower end on the pilot of tlie" engine aud is seen red ati'it's upper end below the casing to the" bolts" e and; the easingisalsosupported at its outer end. against lateral deflection: by the rods.-H",,wliichlatter are securedi ati t'lieirou'ter ends to the sill and tliei'r iiinerends; above: the casing, to tlie bolt'si V 1 llilis evident. that"v numero us sliglitchanges might be made in the general formzand arrangement of" parts" herein. shown and" described without"departihg'fromrtlie' spirit and scope" of my invention, and hence I would have it understood that I do not limit. myself totli'e precise. details of construction shown, butlconsidermyself at" liberty to make such changes and alterationsasi fairlyfalf Within the spirit and scope; of my invention;
