OXYGEN TANK CRADLE Filed Aug. 2, 1945 2 Sheets-Sheet 2 no I F N N l .1 I I m\ g o F l)\ 1 r J E J J Q\ gwuv/wfov JOHN F; HOMER WWLW Patented Jan. 20, 1948 John F. Homer, New! i .i lppl ication August 2, 1945, Serial N5. '1 claims. (or. 224mm) (Granted under the act of March 3, 18 83, as

amended April 30', 1928; 370 0. G. 757) This invention relates to cradles for transporting and supporting cylinders or containers of the oxygen tank type.

More particularly, the invention is directed to a cradle having a cam locking feature, a flat bottom to prevent the load from rolling and pairs of foldable handles. Latching means which engage the handles when they are in extended position and permit ready movement to folded position are also provided.

The improved cradle devices are used in sets of two and one of the devices is provided with a metal arm support for the other device. The arm support preferably includes a semi-circular portion which fits the tank when the arms are in folded position.

Cylindrical objects in tanks may conveniently be carried by two persons with lessened danger of accident.

An object of these improvements is to provide a locking strap type of cradle which can be quickly secured to cylinders.

Another object is to provide a pair of supports having foldable handles and which will prevent rolling of the cylinder when it is put down.

Another object is to provide a light cradle having a quick acting cam locking means and foldable handles.

These and other objects of invention will be manifest from a consideration of the description, claims and drawings in which:

Fig. l is a top plan view of an oxygen tank to which a set of the improved cradles are attached.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a side elevational view of a cradle device with an arm supporting strap.

Fig. 4 is a view of the cradle, in position on a tank, with handles folded.

Referring to the drawing, Fig. 1 shows an oxygen tank I with two'cradles attached. Each cradle comprises a relatively wide metal strap ll shaped to engage the cylinder. Two supporting base portions I2 and I3 are integral with the strap which is bent around as shown and welded at M and I5. The ends of the strap do not come together, but are connected through holes by eye bolt l6 and nuts H. The eyebolt I6 is connected to a pin I8 in bifurcated cam IS. The cam l9 has a knurled handle 20 to move the cam into tank locking position and to release the strap for removal from the tank.

Two pintles 2 I, 22 on opposite sides of the strap pivotally support handles 23 and 24. The handles are kept in position on the pintles by lock nut assemblies 25 and 26 which permit pivotal move- 55 ment of the handles. it. pair g m s s-21 m 28 are secured to the strap II as by welding; and when the handles are in extended position, act as a stop for handles 23, 24, Arm support 30 functions as shown in Fig. 4 to support the handles when they are in folded position.

The parts of both cradles are identical with the exception of the handles and supporting arm. Handles 32 and 33 may rest in support 30 to form a compact unit for storage. Like parts have been given like reference numerals throughout. It is to be noted that the locking cam is quickly operable, that the unit is light in weight and that danger of injury due to rolling tanks and disadvantageous lifting conditions are eliminated.

This invention may be made or used by or for the Government of the United States for governmental purposes without the payment to me of any royalties thereon or therefor.

What I claim is:

1. A cylinder cradle device, including a clamplng strap having a flat bottom portion, locking and release means for the clamping strap, a pair of pivoted handles mounted on the strap and latch stop means for limiting the pivotal movement of the handles.

2. A cylinder cradle means including a clamping strap having fiat bottom portions integral therewith, cam locking and release means for the strap, a pair of pintles on said strap and handles mounted for pivotal movement on said pintles.

3. A cylinder cradle means including a clamping strap having fiat bottom portions integral therewith, an eyebolt and cam locking means for the strap, a handle on said cam, a pair of pintles and a pair of stops on said straps, handles on said pintles which are pivotally moveable to engage the stops or to move to folded position.

4. In the combination set forth in claim 3, further characterized in that the handles are joined together by an arm support member having a semi-circular portion and two straight arm supporting portions.

5. Cylinder transporting means comprising a pair of members removably attached to the respective ends of the cylinder, a pair of handles carried by each of said members and pivot means respectively connecting the handle pairs to the members for selective movement to positions projecting inwardly of the ends of the cylinder and beyond the ends thereof.

6. Cylinder transporting means comprising a pair of members removably attached to the respective ends. of the cylinder, 9. pair of handles spective ends of the cylinder, 3, pair of handles carried by each of said members, and amember carried by one pair of said handles for retaining the other pair of handles against pivotal move ment when the handles are in folded positions.
