PILOT CO'UFLEB STRUCTURE.
application 'nieu august sa, i927.
My invention relates to railway rolling stoclr and consists in an improved pilot and coupler arrangement particularly adapted for "use in locomotives.
My invention relates to aI coupler device which is mounted to s'wing vertically on the pilot so that it may be depressed, from a position in which it functions as a draft trans-` mitting element, to a ,position in which it .tu does not project beyond the pilot at a point elevated above and spaced 'from' the pilot walls but in which it lies in a recess formed in the pilot proper and preferably-forms a j portion of the pilot structure adapted to re- 1a ceive the brunt of animpact with an object on the traclr.
More specifically my invention consists i improvements upon the coupler device illus trated and described in copending applicano tion Serial Number 214,60() filed August 22, 1927, by W. lb. Lentz, and the main object of -my invention is vto produce a coupler and counterbalance possessing the advantages of the laentz structure but also adapted to pro l 25 vide a better mounting for the coupler and its counterbalance.
lln the accompanying drawings which il'- lustrate my inventionn Figure 1 is a side elevation of a locomoao tive pilot beam, pilot, and counterbalanced coupler,
Figure 2 is a longitudinal vertical section through -the same parts, a portion of the locomotive frame being indicated in dot-and- 35 dash lines.
Figure 3 is a top` view of the same parts, a portion thereof being sectioned horizontally to more clearly illustrate their assembly.,
Figured is a front elevation of the pilot to beam and pilot with the coupler removed. Figure 5 is a front elevation of the pilot beam without the pilot.
y rlhe beam is indicated at 1 and the main portion of this beam extends transversely of a5 the locomotive in the usual manner. Below this main portion are downward projections 3 spaced from each other to provide an opening 2 which is closed at the bottom by .a transverse tie 5. rlhe pilot t is mounted on to the beam in the usual inanner'by bolts (i which pass through elongated openings in the pilot whereby the pilot may be adjusted vertically..
Serial No. 214,662.
'lhe pilot is provided with spaced flanges 8 which diverge forwardly and are adapted to receive between them a coupler shanlr 9 provided with the usual coupler head 10'. 'llhe rear portion of this shank. is bifurcated vertically to provide arms 12 and a coupler l vided with a shoulder v adapted to engage an element 21 mounted on the locomotive frame B and this engagement serves to limit the upward movement of member' 11 about its pivot pin 13 and to position the coupler head 10 when lowered as shown in Figure 2. Adjacent portions of the locomotive frame are indicated at and With the above structure, the coupler shanlr, when elevated, is free to rotate in a horizontal plane without requiring any corresponding movement of member 11, and the pin 15 which transmits the forces between shanlr 9 andmember 11 is .in double shear and engages its bearings throughout its length. The pin 13 which transmits the forces between member 11 and the pilot is also in double shear and its bearings in the pilot and counterbalance entend substantially throughout the length of the pin. Hence with this structure there can be no concentrated load applied at a single point on either of 'the pins which would be lilrely to bend the latter and which would necessitate the use of pins of much larger diameter than are necessary with my construction.
i llVith my structure, the width of the openingl inthe pilot beam may be decreased and the walls 22 at the sides of opening 2 may extend at right angles to the front and rear walls .of the pilot 'and form a bearing for the sides of the counterbalance 11.
My structure alsoutilizes other features of the Lentz arrangement, such as the holding pin 16, seated in bearings 18 in anges Ei, which is adapted to engage the lug 19` on the coupler shanlr to hold ythe latter in de-` lil 'lli
ma j
pressed position or to be passed through the opening 17 .in the coupler shank in order 6.o hold the coupler in elevated position.
Obviously the twopart coupler shank and eounterbalance structure which characterizes my invention may be utilized with other pilot and 'beam structure than that illustrated and more specifically described and claimed in the Lentz application, and I contemplate the exclusive use of my invention as'set forth in my claims irrespective of the details of the associated parts.
I claim:
1. A locomotive coupler comprising a forward member having a bifurcated rear end, a rear member forming a counterbalance for said forward member and having a front end fitting in the bifurcation and adapted to receive a horizontal pivot pin between the jaws of thev bifurcation.
2. A locomotive coupler comprising a forward member having vertically spaced arms at its rear end, a rear member forming a counterbalance for said forward member with its front end fitting between said arms and adapted to receive a horizontal pivot pin, and a pin extending through said arms and the adjacent portion of said rear member.
3. In combination, a locomotive pilot, a coupler counterbalanee member pivoted on said pilot to lSwinginl a vertical plane only, and a coupler shank pivoted on said member toswing in a horizontal plane.
4. In combination, a locomotive pilot having transversely spaced flanges, a coupler l counterbalancing member positioned between said flanges, a coupler shank having vertically v.spaced jaws at itsrear end for receiving the forward end of said member, a vertically disposed pin extending through said jaws and member, and a horizontally disposed pin extending through said member and flanges, said pins serving to transmit bufiing and draft forces between said shank and member and between the latter and said pilot.
5. In combination, a locomotive pilot having transversely spaced flanges, a coupler counterbalancing member positioned between said flanges, a coupler shank having vertically spaced jaws on its rear end for receiving the forward end of said member, a vertically disposed pin extending through said jaws and member, and a horizontally disposed pin extending through said member and flanges, said vertical pin serving to transmit bufiing and draft forces between said shank and member and said horizontal pin serving to transmit such forces between said member and` pilot.
G. A locomotive coupler comprising a forward member having a bifurcated rear end, a rear member forming a counterbalanee for ysaid forward member and having a front end fitting in the bifurcation and having a bearing for a horizontal pivot pin between the jaws of the bifurcation, said jaws extending rearwardly of said bearing, and a vertically disposed pivot pin extending through the rearward portion of said jaws and through said rear member to permit pivotal horizontal movement of said forward member relative to said rear member.
In testimony whereof, I have hereunto affixed my signature this 5th day of Aug.,
EINAR G. HALLQUIST.
