United States Patent SUPPORTFOR DETACHABLE HANGER 'Lewis E. Hamel, 999 Bay St., Rochester 9, N.Y. Filed Oct. 5, 1961', Ser. No. 143,141 4 Claims. (Cl. 248-340) This invention relates to a support for a detachable hanger such as employed in holding beef halves, beef quarters and other heavy meat units in freight cars during transportation, and it'has for its purpose to provide a permanent support in the car to which the detachable hanger can readily necessary.
A particular purpose of the invention is to afford as part of the support a hook to which the detachable hanger canreadily be applied and which has a locking device that securely holds the hanger in place on the hook without chance of accidental displacement andremoval.
Still another object of the invention is to provide in conjunction with such a hook a locking device that can readily be moved upwardly out of locking position and which when in its unlocking position can be swung out of the way to afford ample space for easy insertion or removal of a hanger.
An additional purpose is to afford ahook of the character mentioned WhlCh is adapted to support one or two. detachable hangers with theirrespe'ctive loads, andin which the load is always in vertical alinement with the point of support of the hook.
Another object of the invention is to provide a locking device such as described above, and which when in its unlocking position can be turned to a predetermined point at which his released and automatically returned by a spring to'locking position to hold a hanger 'or hangers on the hook, the locking device being guided to its locking position by means provided on the hook for this purpose and cooperating with the locking device.
A further purpose of the invention is to provide a hook such as. mentioned with resilient'cushioning means which permits slight. downward movement of the hook when a be applied, and easily removed when t sufiicient load is exerted, and which cushioning means will function indefinitely with just the proper degree of tension. and resilience and will always insure returning the hook with its suspended weight to normal position without affecting the resilient means due to tension changes. a I
I To these and other ends the invention consists in the construction and arrangement of parts that will appear clearlyafro'm the following description when read incon- -junction with the accompanying drawings, the novel features being pointed, out inthe claims, following the I r H 4 opening, 13and functioning to guide theplate in its upward and downward movement along the rib' 15. 17 is specification.

The bottom of the clevis which is indicated at 3 has an opening therein that receives the uppervertical portion 4 of the hook which is preferably of stainless steel, and the upper end of the portion 4 is provided with an integral head 5.
Extending downwardly from the vertical portion 4 of the hook at an approximate 45 angle thereto is theinclined portion 6 which terminates in a relatively wide horizontal bottom portion 7 which connects with an upwardly inclined terminal portion 8, the inner edge of which is substantially parallel to the inner edge of the downwardly inclined portion 6 of the hook, while the .terminal portion 8 is provided at. its outer end with a tapered extremity 9 for a purpose that will appear presently. I
11 designates a lockingmernber or plate having upwardly inclined sides "12,; and an opening 13 which surrounds and is slidable on the portions 4 and 6 of the hook, while at its outer end the locking plate is provided with a cutout portion or recess 14which engages the tapered outer end 9 of the hook and is thereby held against further downward movement.
When in such locking position, the plate his in engagement withthe inclined portion 6 of the hook atsuch a point, as shown in FIG. 1, thatit; cannot bedislodged from locking position by an upward-motion of the outer end ofthe plate, but 'can' 'only be moved out of locking position by the operator initially taking hold of the inner end of the locking plate and moving itupwardly in line as shown in FIG. 2. In thisjposition it is lifted above and "out of the path of the open part of the hook which is then free to permit removal or positioning of ahanger governing movement of the locking: device toits locking- FIG/ is a'detailed sectional view through the center of the upper part of the hangen'and 1 a FIG. 6 is a side elevation'lookingl from right 'to left I a Inj'lorder tojperrnit a slight "the hook the clevis withfa resilient action that" always insures return of th'hook't its initial uppermost position on the hoolQ...v 1 4 I a 7 When turned 'through'such 90 aiigle', the locking plate is held-in its upper position by a rib,15 formed on the hook, while 16 is a slot in the locking plate adjacent topthe a spring, surrounding the hook and locatedbetween the locking plate 11 and the bottom of the clevis, the spring acting to force the locking plate downwardly .into locking'pos'ition when the plate 11.is turned to theipredeten mined point for/engagement of slot 16 ,with the rib"15.

er verti- .callportion flpf the he k isprovided' with awas e s' of urethane, overlying a thin inetalfwasheii l9'i which is' of somewhat greater diameterjthan the urethane washer ing powder #58029, supplied by B. F. Goodrich Chemical Company, 3135 Euclid Avenue, Cleveland 15, Ohio. This is a resilientmaterial withstanding-about 50% compression, and while recovering its original shape when released, it will stand up longer and more efiiciently than any metal or rubber spring. The metal or steel washers 19 are preferably about ,4 thick and somewhat wider than the urethane washers which are about A" thick. By making the steel washers of greater diameter than the urethane washers, the latter are prevented from being squeezed and cut when subjected to the pressure resulting from the weight hanging on the hook.
In assembling the structure, the hook with the urethane and steel washers arranged thereon is first inserted with the outer tapered end 9 and outer inclined portion 8 through the openingin the bottom of the clevis, until the integral stainless steel head 5,'and the urethane and steel washers 18 and 19 are inplace as shown in FIG. 1. Projections 21 are then swaged on the vertical portion 4 of the hook to hold the latter against upward movement, and the rib is also swaged thereon, following which spring 17 and locking plate 11 are successively introduced over the outer end of the hook. The hook can then be 'move'd to its uppermost position above the rib 15, or turned and released into locking position, as shown in FIG. 1, after a hanger with its load is positioned on the hook.
, The hanger cannot then be removed until the operator first lifts the inner end of the locking plate to release it and permit its removal to its uppermost position surrounding the upper part 4 of the hook, as shown in FIG.
2. The hanger with its load can then be removed and another hanger placed in position resting on the bottom horizontal portion '7 of the hook, which is shaped suificiently wide so as to accommodate at the same time two hangers with their respective loads resting on the portions 7and 8 of the hook, if this be desirable.
When the hanger or hangers are in place, the locking plate 11 is turned back to its initial position with its slot 16 in alignment with the rib 15 on the hook, and when the locking plate reaches this position, the spring 17 automatically acts to move it downwardly to locking engagernentwith the inclined part 6 of the hook and the tapered outer end 9, the tapered character of which facilitates .engaging the hangers on the hook;
