Definitions
- This invention relates to car couplings of the transition type which are designed for use in those instances where all the cars of a railroad are not equipped with automatic couplers and it becomes necessary at times to connect an automatic coupler with a conpler of the old hook form.
- the present invention seeks to provide a transition coupling which may be easily applied to the drawhead of an automatic coupler and when applied will be secure against premature or accidental removal; may be easily shifted out of the way when two automatic couplers are to be connected; willeflectually connect an automatic coupler with a hook coupler, and will possess sufficient flexibility to accommodate unequal loading of the cars.
- Figure 1 is a plan view of our improved transition coupling in use
- Figure 2 is a side view thereof
- Figure 3 is a side elevation showing the initial position when the device is to be assembled with the automatic coupler
- Figure 4 is a diagrammatic elevation showing the positions assumed when the coupled cars approach each other;
- Figure 5 is'an illustration of the position given the transition device when two automatic couplers are to be connected
- Figure 6 is a detail of the bail or trunnion link
- Figures 7 and 8 are perspective views showing a form of the invention differing in some details from the form shown in the preceding figures.
- the drawhead 1 of the automatic coupler is formed with a trunnion 2 on its knuckle 1924. Serial in. 724,818.
- a trunnion hook, bail or link 4 is also provided and as shown most clearly in Figure 6-, is of a general bail formation having parallel side members 5 and a connecting or bridge member 6 which is disposed obliquely relative to the side members whereby an acute angle 7 is formed at the front end of the bail adjacent the guard arm side thereof.
- the rear ends of the side members of the bail are formed into trunnion-engaging hooks 8 which are preferably flat-sided and properly proportioned to permit the connecting link 9 to be engaged therewith, said link 9 carrying the hook link 10 adapted to engage the coupler hook 11, as shown and as will be understood.
- the connecting link 9 is engaged with the bail t.
- the key or other fastening which secures the drawhead is released and the drawhead is drawn forwardly five or six inches which will permit the bail to be laid back over the top of the drawhead, as shown in Figure 3, with the hook ends 8 thereof engaging the trunnions, whereupon the bail is rotated forwardly about the trunnions until it assumes its normal position shown in Figure 2.
- center line of the pull will be at one side of the actual center line of the drawhead 1, the greater portion of the pull being applied to the trunnion on the guard arm side of the drawhead so that the drawhead is pulled off center and more clearance is provided for the link 9.
- the pull in the arm 6 is considerably less than in the arm 4, and therefore cross sectional area may be proportionately decreased whereby more space for the desired flexibility to links 9 and 10 is obtained in all positions.
- the links 9 and 10 with the bail or link 4 impart great fleX- ibility to the transition device so that it readily accommodates itself to the difference in heights of the cars whether due to loading or to the build of the cars, and, upon reference to Figure 4, it will be noted that when the cars come together the transition links will collapse or fold into the knuckle chamber or mouth of the drawhead and proper engagement with the hook coupler will be maintained without any amming or damage to the links 9 and 10.
- the transition device is arranged as shown in F igures 5 and 8, the links 9 and 10 being swung to the knuckle side of the drawhead and held in such position out of the way by the engagement of the upstanding lugs 28.
- This adaptability of our device makes feasible the formation of a hole in the top of the lock casing of the automatic coupler and the employment of top-lift couplers.
- FIGS 7 and 8 is shown a form of the invention in which the drawhead 20 is provided with a trunnion on its knuckle side to be engaged by a hook at the end of the bail, but on the guard arm side of the drawhead a hook 21 is formed while the corresponding end of the bail, is formed into an eye 22 to engage said hook.
- the drawhead is also provided with upstanding lugs 23 adjacent the pivot of the knuckle behind which the hook link and the connecting link may be engaged when two automatic couplers are to be coupled.
- the operation of this form of the invention is just the same as the operation of the first-described form.
- 111 a transition car coupling, the combination with a drawhead of the automatic type, of holding elements on the sides of the drawhead, and a bail constructed with open sided terminals to fit to the holding elements when extending rearwardly over the drawhead and rock forwardly into look ing engagement therewith.
- a transition car coupling the combination of a drawhead having laterally projecting trunnions on its opposite sides, a bail consisting of side members of unequal length and an obliquely disposed bridge member connecting the front ends of the side members and forming an acute angle with the longer side member, the rear ends of the side members forming flatsided hooks to engage the trunnions, and a coupling element carried by the bail and normally seating in the acute angle thereof.
