CAR-COUPLING.

K SPECIFICATION forming part of Letters Patent No. 698,433, dated April 29, 1902.

Application filed February 15, 1902. Serial. No. 94,259. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID L. BOOK, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Car-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 car-couplings, has especial reference to that class of couplings known as the Master Oar-Builders or Janney type for automatic coupling, and has for its object certain improvements in construc tion, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a top plan view with the head of the coupling in transverse or horizontal section, showing the hook or knuckle in position for automatic coupling;Fig. 2, a perspective, on an enlarged scale, of the front part or head of the coupling with the hook and the latch removed; Fig. 8, a like view of the hookdetached; and Fig. 4:, a like view of the latch, also detached.

Reference being had to the drawings and the letters thereon, A indicates the body. of the coupling, provided with slot at for the reception of the usual draft-pin and a shoulder 1), which engages the timber of a carframe; B, the head of thecoupling, which is provided with lugs c c, to which the hook or knuckle C is pivotally secured to swing laterally therein, a recess dto receive the tongue 6 of the hook, a hornf, and a shunting-seat g, inclined toward the horn to facilitate coupling while cars are standing on or rounding a curve in a road-bed.

The hook Cis provided with a laterallyreduced member h, which engages the lugs c c and is secured in position by a pin a, which passes through the lugs and the hook and has a recess 7c in the rear side of the tongue, forminga transverse shoulderl,which takes part of the strain of the draft in pulling and part of the shunting effect in pushing a car or a train of cars. Part of the shunting effect is also taken up by the faces m and n on the tongue 6 and the corresponding faces up in the recess d.

The head B is provided with a side D, which is approximately parallel with the line of draft and may therefore be called straight in contradistinction to the curved or rounded heads in common use, and in this side of the head a pocket gis formed, having shunting shoulders or seats r r and s, the latter beingat the rear end of the pocket, and in this pocket a laterally-swinging latch provided with lateral extensions 1' 1", which engage the seats '1' r at the rear ends of the extensions, is pivotally secured by a pin 16, and the flat part it of the latch in front of the pin t is held in engagement with the fiat rear side 0), and the end w of the latch is held in engagement with the shoulder Z of the hook C by a spring w in said pocket q under the rear end y of the latch, and the end 2 of the latch engages the seat 8 of the pocket as a further or additional draft and shunting resisting medium.

The latch E is drawn out of the pocket at its front end to release the hook C for un-.

coupling by any suitable means, such as an eyebolt z, to which a rod or chain (not shown) may be attached.

The coupling is designed on such lines as to couple with the prevailing type of couplings and to work in conjunction therewith without undue strain on either,

Having thus fully described my invention, what I claim is- 1. A car-coupling having a head provided with a side approximately parallel with the line of draft, a pocketin said side having shunting-shoulders in the sides of the pocket, and a laterally-swinging hook having a transverse shoulder, in combination with a laterally-swinging latch lying within andjpivoted in said pocket with its front end normallyengaging the shoulder on the hook,and having lateral extensions engaging said shuntingshoulders.

2. A car-coupling having a pocket in the side of the head provided with shunting-shoulders in the sides and at the rear end of the pocket, and a laterally-swinging hook having rear end engaging the rear wall of said pocket,

a transverse shoulder; in combination with a and an inelosed spring engaging the latch. 10 laterally-swinging latch having lateral and In testimony whereof I aflix my signature rearward extensions, lying within and pivin presence of two witnesses.

oted in said pocket with its front end nor- DAVID L. BOOK. mally engaging the shoulders on the hook, Witnesses: its lateral'extensions engaging the shunting- W. S. BOGK,

shoulders in the sides of the pocket, and its THOMAS P. KEETLEY.
