Feb. 2, 1960 A. E. F. JOHNSON SUPPORT STAND Filed Sept. 15, 1955 ll Illllllllllilll IN V EN W ATT f SUPPORT STAND Axel E. F. Johnson, Cincinnati, Ohio, assignor to American Hospital Supply Corporation, Evanston, 111., a corporation of Illinois Application September 15, 1955, Serial No. 534,546 2 Claims. (Cl. 248-194) This invention relates to a support stand, and the invention is particularly useful .as'a stand support for the bails of bottles or other containers, etc,

An object of the invention is to provide a support structure which engages the bails of bottles so as to support the bottles firmly in position while providing adjustable resilient means for frictionally engaging and holding the bottles against movement. in an extensible telescoping stand structure, means whereby the extensible portions are firmly held in position while at the same time supporting a hook member held in position by a resilient locking means. A still further object is to provide in such a stand structure a weight device within the base which is effective in clamping the supporting legs in position and providing quick assembly means for uniting the base and leg structures. Yet a further object is to provide a novel form of bail-supporting stand of extremely great stability, while aifording a sounddampening and stabilizing support for a plurality of bottles or containers equipped with bails and for prevent ing breakage of the bottles, etc. Other specific objects and advantages will appear as the specification proceeds.

The invention is shown, in an illustrative embodiment, by the accompanying drawing, in which:

Figure 1 is a perspective view of a stand embodying my invention; Fig. 2, an enlarged vertical sectional view; Fig. 3, a perspective view of the bail hook member employed; and Fig. 4, a broken perspective view of the base and leg assembly, the several parts being shown in spaced-apart relation.

In the illustration given, designates a rod or top extensible member, and slidably mounted thereon is a sleeve 11 formed of rubber or other resilient material. Upon the rod 10 rests an inverted U-shaped hook member 12 having a central web portion 13 adapted to rest upon the top of the rod 10 and having depending spring legs 14 engaging the sides of the rod 10, the legs being turned sharply upwardly at their bottoms to provide hook lips 15. The hook lips 15 preferably widen laterally as they extend upwardly to provide flared top rims 16, as shown best in Fig. 3. The inverted U-shaped member 12 is secured in the position shown in Fig. 2 by a resilient locking member or cap 17. The resilient member 17 provldes a cushion against which the bails bear as they are drawn into the books 15 therebelow, while at the same time anchoring the hook member 12 against lateral movement and dampening the sound as the bails are moved into position. In the specific illustration given, a bottle 18 is shown equipped with a bail band 19 and a bail 20 engages the hook 15. The slidable sleeve 11 is adjusted along the length of the rod 10 so as to engage the bottle and hold it firmly and tightly in position. With the structure shown, in which the hook portions 15 of the member 12 lie close to the rod 10, the weight of the bottle presses it firmly against the resilient sleeve 11, with the result that the sleeve grips the bottle and anchors it against'sidewise tilting, etc.

The rod 10 extends downwardly into a centrally- A further object is to provide,

apertured fitting member 21 threadedly recessedto receive a wing screw 22. The fitting 21 is provided with 'an annular groove 23, anda tubular member 24 telescopically receives the member- 23 and the metal ofthe member 24 is crimped or rolled into the groove 23, as indicated at 25 to form a rigid interlock. The tube24, is apertured to receive the wing screw 22. For further steadying and.

anchoring the rod 10 within the tubular member 24, a

compression spring 26 may be extended through a transverse opening 27 in the rod'10.

A second fitting 28 is inserted within the lower end of the tubular member 24 and is also provided with an annular groove 29 into which the metal of the tube 24 is rolled or crimped to form an interlock at 30. The fitting 28 is provided with an extension 31 having at its lower end a threaded portion 32 adapted to be engaged by a nut 33. A base cup 34 is aperturedon three sides to receive the base legs 35 which are provided at their outer ends with caps 36 and with feet 37. The feet 37 are provided with screw extensions 38 adapted to be engaged at their upper ends with nuts 39, and the bases of the legs 37 are enclosed within resilient caps 40.

In order to weight the base and at the same time pro? vide means for securing the legs 35 in position, I provide two complementary cast iron members 41 and 42,. each.

having therein three semi-circular recesses 43 and with knobs or projections 44 extending into each recess and adapted to engage pre-drilled holes 45 in the legs 35. The members 41 and 42 are provided with central openings 46 and 47, respectively, for receiving the extension 31 of the fitting 28.

Operation In the operation of the structure, the stand is assembled by bringing the

extensible members

10 and 24 into the relation shown best in Fig. 2. The legs 35 are assembled within the casting members 41 and 42 with the recesses 45 receiving the projections 44 of the two castings, and the entire base members, including the'cup 34, castings 41 and 42, and the three legs 35 are secured in place by the single nut 33, as illustrated best in Fig. 2. The rod 10 is extended to the desired height and clamped in position by the wing screw 22. One or two bottles may then be supported upon the hooks 15 by bringing the bails against the resilient member 17 and downwardly into the hook recesses, with the result that the bails are thus held close to the rod 10 and the weight of each bottle bears firmly against the resilient sleeve 11, whereby the bottles are anchored against lateral movement. is adjustable to bring it into engagement with the portion of the bottle which swings closest to the rod 10, and the sleeve dampens the noise brought about during the positioning of the bottle or the adjusting of the same during administration of the'parenteral liquids or other liquids thereon, and further prevents breakage of bottles by striking the metal standard.

Any suitable material may be employed in the manufacture of the stand. The rod may be formed of stainless steel and the tubing may also be stainless steel clad tubing and the base cover 34 for the cast iron plates 41 and 42 may similarly be formed of stainless steel. It will be understood that any form of metal, plastic, or other suitable material may be utilized in the forming of the Q tary base plates having aligned vertical and central open- Patented Feb. 2, 1960" The sleeve 11' ings therethrough and having a plurality of outwardly extending and uniformly spaced apertures, each of said apertures being defined byicomplementary recesses extending outwardly along the opp osing surfaces o f each of said plates between the central opening and the periphery thereof, a plurality of outwardly extending legs having" theirfirn'ler. end portions received within the apertures of said: base plates, said end portions of said legs having upperand lower surfaces seated within the complementary recesses of said plates and havingwertical crosssectional dimensions greater than the combined vertical dimensions ofeach pair of said complementary recesses, whereby, whensaid inner end portions of said legs are disposed within said apertures the opposing surfaces ofsaid base plates are spaced vertically apart, vertical projections provided by at least'one-of said-plates within the recesses thereof, said projections being shorter than'the vertical cross 'sectional dimensions ofsaid legs, vertical openings provided-by said legs for receivingsaid projeetions and a threaded fitting extending through: the aligned vertical openings of said base plates and securing the same togather in clamping relation to-the innerend portionsof the vertical cross-sectional dimensions of each of said, inner end portions of i said legs being greater than the combined vertical dimensions of each pair of said complementary recesses, whereby, when said leg inner end portions are disposed within said apertures the opposing surfaces of said base plates are spaced vertically apart,
