Dec. 22, 1953 E. R. HINCIKLE HYDRAULIC SPRING HANGER Filed May 28, 1952 NJ II 0: I N I I 5g i I I INVENTOR.

Patented Dec. 22, 1953 UNITED STATES PATENT OFFICE 4 Claims,

The present invention relates to a means for suspending beef rails in moving vehicles, such as for instance, rolling stock, trucks, and other land or water conveyances. While the invention is principally concerned with the shipment of large sides of beef and other meats, the same principles of construction may also be applied for shipping other types of bulky commodities.

In my prior copending application, Serial No. 257,6 9, filed November 21, 1951, I have disclosed means and methods of mounting individual hydraulic spring hangers, to which eye-bolts or ring bolts could be attached from which the sides of beef and other objects of the same type might be suspended.

It has been pointed out in my companion application that because of the motion of the cars, the beef suspended by the usual hook may easily be damaged, either by shaking and movement of the car itself, or because the beef may be thrown ofi the hook or wear through the hook as the result of which it will be bruised and damaged in contact with the walls or floors.

In the present application the construction deals principally with a means and method of suspending the entire beef rail; that is, a, rail from which the'beef may be suspended by a suitable hook, the rail itself taking the greater part of the jar, vibration or shaking so that the beef will D be given a smooth ride and not be damaged.

I have found that an ordinary hook may be used if the whole rail itself is supported on 'a hydraulic suspension in such a way that the motion and vibration of the car is damped by the suspension means which acts between the hook and the fixed support.

The advantage of this type of construction is that far fewer suspension hydraulic hangers need be used and no special provision need be made for the types of hooks to be used, but any good type of hook which will not fall offthe beam will be sufiicient.

Without further describing the merits and advantages of the present invention, the invention will be more fully described in the specification set forth below when taken in connection with the drawings illustrating an embodiment of the invention, in which:

Figure 1 shows a section through the suspension hanger and the suspended beam of my invention.

Figure 2 shows a top view of the hydraulic hanger shown in section in Figure 1 with the top cover removed, and

Figure 3 shows a vertical section through the supporting beams from which the suspension beam is suspended.

In the arrangement indicated in the figures, the hanger element I may be provided with side flanges 2 and 3, coextensive with one side of the hanger unit by means of which the whole unit may be attached to the beam 5 which may be a cross beamby means of suitable attaching bolts 4, 4, etc., passing through holes in the flanges and into the sides of the beam; The hanger unit I may be somewhat similar in constructionto that described in my copending application.- The unit comprises a casing with a base 6 and side walls '5, 3, 5 and Hi, forming a box which may be covered by a cover In. The base 6 may have suitably placed upwardly projecting bosses H, Ii. which form shoulders for the helical springs i2, :2, etc. The helical springs may extend from the base 5 upwards to a, top plate l3 which may if desired, also have downwardly projecting bosses coaxial with the helical springs. Suitable rods or studs 14 permanently secured at the center of the bosses ll extend upwards coaxially with the helical spring 12 through the top plate l3 and are capped over the top plate l3 by washers I5 and nuts I6 to secure the springs and plate in place with a uniform tension. The washers and. nuts as indicated in the plan view in Figure 2, show'the uniform distribution of the helical springs beneath the whole plate l3. Extending upward through the base ii are two walled passages I1 and I8 which extend substantially halfway up into the box or casing and through which slide fitting rods I9 and 20 extend coaxial with a center bore in the walled passages I! and I8 respectively. The rods [9 and 20 pass upward through the box and through the plate l3. The ends of the rods have caps or heads 2| and 22 firmly attached or welded to them which caps have outwardly extending flange plates 23 and 24 respectively which are bolted, riveted or attached by screws as indicated at 25 to the plate I3.

Surrounding the rods [9 and 2!! and extending from the top of the passages l1 and [8 are flexible collars 26 and 21 which at one end are held by clamps 28 and 29 to the tops of the passages l1 and I8 and extend to the plate I? to which the other end of the collars are clamped inside of the box surrounding the well and coils to pass slowly through the plate as the plate is moved downward by the weight acting against the rods [9 and 20. For this purpose the plate [3 may have a sliding fit against the inside of the walls I, 8, 9 and H! so that as the plate is being drawn downward against the oil or other hydraulic liquid which may be inside the casing, the liquid will be forced up through the orifices 30 and provide a damping action in parallel to the action of the coilsprings. This action will work in both directions inasmuch as when the plate tends to rise the Vacuum created under the plate will draw the oil back into the cavity beneath the plate and thereby damp the motion in an upward direction as well as in a downward direction.

The rods it and 20 carry the bracket 3i which is gener-rectangular or square with an open: end or U shaped in section with two outwardly extending flanges 3-2 through which the rods l9 and 20 pass. These rods are threaded and provided with nuts 33 and Fi l respectively securely bolting the U shaped bracket in place.

The U-shaped bracket carries a closely fitting beam 35 which may be run transversely to the beams and 5 to which the hydraulic hangers i and l are attached. The complete beam 35 may be supported by only two such hydraulic hangers. If the beams 5, 5' run crosswise of the van or car, then the beam 35 will run lengthwise of the car. The beams 5 5' can be equipped with a plurality of sets of hydraulic hangers i and l, thereby making it possible to suspend a series of longitudinal beams 35 in the van or train. If the car or van is to be used for shipment of other commodities, the beams 35 may be removed.

The hydraulic hangers i are shown attached to cross beams of a van or car but they may be attached, if desired, to the side walls or by running the flange across the top edge of the casing or box, they may be attached to the ceiling with the bracket 3| hanging downward for holding crosswise or longitudinal beams.

It will be seen therefore that this invention provides considerable latitude for the arrangement of cross or longitudinal beamsfor cars or vans. The number of hydraulic hangers for a beef rail will depend upon the load to be carried'but there will be only a few compared to the number of sides of beef carried.

Any type of suspension hook may be used on the beam: 35;,but preferably one should be used which is secure on the beam. In this respect it is desired that a hanger or hook attached to the beam 35 extend around all three sides and that the hookitself preferably extend directly beneath the-suspension beam.

Where the hanger is to support considerable weight an' angle plate lilmayextend from the top of the hanger box over the cross beams 5 and 5', so that the load carried by the-hanger will be supported by the entire cross beams rather than only a portion of them. 7
