Specification of Reissued Letters Patent. Reissued Oct, 26, 1909, Original No. 812,385, dated February 13, 1906, Serial No. 285,374. Application for reissue filed June 4, 1907.

To all whom it may concern:

Be it known-that I, EDGAR E. TURNEY, of Lima, county of Allen, and State of Ohio, have invented certain new and useful Improvements in Operating Mechanism for Automatic Car-Couplers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and ,to the figures of reference marked thereon, which form part of this specification. i

This invention relates to devices for operating automatic carcouplers; and it has for its object, to provide simple and effective means for adjusting the arm upon the operating-rod and also the connection between said arm and the loek-stem of the coupler.

The use of the ordinary one-piece operating-rod connected to the couplerdock by a short chain ha: proven ineffective, owing to ihefact that all cars have more or less free movement or slack in the rear end attachment of their couplers, and the ordinary rod and chain do not posses sutlieient flexibility to permit such free movement.

ln caurying out my invention I provide upon the operating-rod. an arm capable of being adjusted thereon, and I provide said arm with an elongated slot whereby the conncction between said arm and the lock-stem of the coupler has a movement to permit free movement of the cars without .in the least affecting the efficientoperation of the coup lelplocking mechanism.

In carrying out my invention I employ the novel. combination and arrangement of parts hereinafter shown, described and claimed. I

In the drawings,

Figure 1 is a perspective view showing my invention applied to the end of a car in position for operating an automatic earcoupler,

Figure 2 is an elevation in detail of the inner end of the operating-rod, the bushing, and the adjustable arm, showing said parts as they appear before being assembled,

Figure 3 is an end view of the bushing detached. f ronnthe operating-rod,

Figure 4 is a front view of the cl evis, and

Figure 5 is a side view of the clevis.

Referring to the parts, 1 is an operatingrod having the usual bent handle 2, and the same is mounted for 3 and 4. The inner end of the operating-rod is made non-circular and preferably square,

adjustable to the rod is readily accomplished by mscrewing the nut 12, the serrations upon the adjacent faces of the arm and the bushing being then disengaged. At the outer end of the arm 10 is provided a slot 13, ada ted to receivea pin 14 at the upper end of t e connecting-Clovis 15. substantially similar parts-16 and 17, re spectively, 18, one for attachment to the end of the operating-arm and the other for attachment to the eye of the lock-stem 19 of the cou )ler. The faces of the parts 16 and 17 of the cievis are provided With transverse serrations 20, and each. part also has a slot 21, through which a bolt 22 passes, the latter holding the clevis parts in rigid relation when adjusted to the proper length.

On assembling the parts the operatingarm and the serrated bushing are removed readily placed in position by being insertc The bushing 6 is then placed upon the end of the rod, and the operating-arm is placed upon the bushing and position, the nut 12 securing the same when adjusted. This arrangement is of obvious advantage over the one-piece operating rod and arm, the latter being secured to the car with ditlicnlty. The slot at the outer end of the arm 10, along which the adjustable clevls OHIO, A CORPORATION operation upon castings as at 5, to receive thereon a bushing or sleeve.

Clevis 15 comprises two from the operating-rod, the latter then being,

through the openings in the castings 3 and 4,

adjusted to the propersition. The ad ustment of the arm relative each having a bifurcatedportioli 30 x ler-lock, of an operating-rod, a bushin that the S at the on r' ing-arm as e a near ltlgrllt coupler-ope tting mechani operates, permits the expansion and contractlon of t e draft=springs and supplies the requisite flexibility ne movement of the cars sary tant to insul;

conveniently adjustable in the direction of its length.

It will thus be seen that the parts are arranged to permit perfect flexibility during the operation of cou ling the cars and thatthey are consequent y relieved from undue strain anddanger of breakage.

The utility of the invention will be apparent.

Having thusdescribed my invent ion'and illustrated its use, what I claim as new, and

desire to secure by Letters Patentis the followin 1. a means, for operating automatic car-couplers, the combination with the coup secured, against rotation 11 on said r an arm ad ustable upon sai bushing, andra clevis slidably connected with the outer end of said arm and connected at its'lower end with the coupler-lock, substantially 111s de- 2. In a means for operatin z'mtomatic car-couplers, the combination with the coupler-lock, of an operating-rod, a bushing secured a ainst rotation upon' said rod, an arm adjusta le u on said bushing, and a clevis connecting t 10 arm withthe coupler-lock,

said clevis being slidably carriedat the outer car-con lers, an operating-r0 end of said arm and havin means for ad- {usting the same in the irection of its ength, substantially as described.

3. In a means for .operatin automatic having a square end, a bushing having avsquare erforation to fit upon said end and eld against rotation thereon, said bushing having a flange provided with radial teeth, a1

arm mounted u on .the bushing and also provided with radial teeth to engage the teeth upon the flan gated slot at its outer end, a nut upon the rod to secure the arm when adjusted relative to the bushing, and a clevis connecting the slotted end of the coupler-arm with the coupler-lock, said clevis consisting of two parts having interenga ing teeth to permit the same to be adjuste in the direction of their length, and means for securin said clevis parts in adjusted position, su stantially as described.

:4. In a means for operating automatic car-couplers, the combination with the coupler-lock, of an operating-rod, an arm secured to the operating-rod, and longitudinally slotted, at 1ts outer end and a connectingvrod adjustable in length provided with a pm at its u per end enga g the slot in the arm 5. n 'a means or operatin automatic ear-couplers, the combination w1th the coupler-lock, of an operating rod, a bushing secured a ainst rotation upon said rod, an arm adjusta leupon said bushing, and a member slidably connected with the outer end of said arm andconnected at its lower end with the coupler-lock, substantially as described. In testimony whereof I have hereunto si ed my name in the presence of,the two so scribed witnesses.
