GRIPPING MEMBER FOR CYLINDERS.

Application filed September-.22, 1923. Serial No. 664,287.

My invention relates to cylinders used for I holding ammonia, acetylene and other gases, and particularly relates to cylinders of the seamlessdrawn steel type, having an integral head, or bottom end, formed with rounded surfaces. 4

The object of my invention is to provide means upon the integral head of the cyl inder adapted for gripping the cylinder by hand or by hoist hooks; and afurther object is to provide various forms of gripping means adapted for carrying out my invention and also to construct thegripping. means so that they will form a broad and 13 firm base for supporting the cylinders in a vertical position.

Heretofore it has been very difficult to handle a cylinder having a rounded drawnhead, as it was impossible to find a place 90 to get a hand hold or to secure a hoist hook.

. Some forms of cylinders are made of tubing welded lengthwise of the cylinders and the heads are inset. These cylinders have the advantage of being readily handled. The seamless drawn cylinders now in general use have one head formed integral with the body and the opposite end formed with aseparate inset head, secured in a manner well known in the art. My invention provides a gripping member which is secured to the integral head of the cylinder so that it may be eadily handled.

Referrin to the accompanying drawing, Fig. 1, is a central longitudinal section through a seamless drawn cylinder, showing my improved gripping member secured thereto and engaged by hoist hooks; Fig. 2, is an end view of Fig. -1, the hoist hooks being omitted; Figs. 3 to 7 are longitudinal sectional views of a .portion of a cylinder,

embodying various forms of-gripping members; Fig. 8, is an end view of Fig. 7 Fig. 9 is a sectional view of the end of a cylinder showing a still different type of gripping member; Fig. 10, is an end view of Fig. 9; Fig. 11, is a sectional view of one end of a cylinder showing a still difierent type of gripping member; Fig. 12, is an end view of Fig. 11; Fig. 13, is a sectional view of the end of a cylinder showing a still different form of gripping member; Fig. 14;, is

an end view of Fig. 13; and Figs; 15 to 19,

are sectional views of portions of cylinders showing still different forms of gripping members.

In the accompanying drawings in which attaching the hook 7, of the hoist, and

like reference characters refer to like parts, 1 represents the body of a seamless drawncylinder having an integral head, or base 2, formed upon the cylindrical body 1. The opposite head to top 3 is inset and secured to the-body 1- Said head 3 forms an outwardly projecting flange which provides means for readily gripping the cylinder by hand, or by a hook 5, of the hoist 6. The opposite end having the drawn head 2 .presents rounded surfaces which will not permit a hook to be attached and also making it diflicult' to lift this end of the cylinder by hand.

, My invention consists of providing a gripping member, such as shown at 8, Fig. 1, which member forms a means for readily which also forms a hand grip for lifting the'rounded end of the cylinder.

The gripping member 8, shown in Fig. 1, 4 is constructed with a hemispherical body 9, adapted to fit into the concaved portion of the drawn head 2 of the cylinder. The gripping member 8 also has an annular} flange 10, projecting inwardly, thus providing means for securing the hook 7. The. body 9 of the member 8 is secured to the cylinder head 2 by spot welding at the points 12, or b electric welding.

, The form 0 gripping member 14, shown in Fig. 3, consists of an annular collar 15,

having an inwardly projecting flange 16,

secured by welding at the points 17, in the I0 manner above described.

Fig. 4, illustrates a gripping member 20, consisting of a flat ring having its outer edge attached to the head 2 by welding atthe points 21.

Fig. 5, illustrates a form of gripping member consisting of a ring 23, of square crossesection, which is secured to the cylinder head as above described.

Fig. 6, shows a gripping member consistv ing of a ring 25 of circular cross-section, secured to the' cylinder head by welding.

Figs. 7 and 8, illustrate a gripping member formed of a bar 26, having its ends welded to the head of the cylinder.

Figs. 9 and 10, illustrate a form of gripping member consisting of aJink, or elliptical ring 28, secured to the head 2, in a plane extending parallel with the longitudinal axis of the cylinder.

A gripping member 30'is shown in Figs. 11 and 12, in the form of a cross-bar having its secured to the head 2 and a brace bar 31 is secured between the head 2 and 'the bar 30, in line with the longitudinal welded tothe head 2.

The gripping member 35, shown in Fig. 15,'consists of a collanhaving a cylindrical portion 36'adapted to fit over theend of the cylinder 1 and which is welded to the cylinder at the points 37. A conical flange 38 forms part of the collar 36. Said flange 38 extends inwardly and also extends beyond the head 2 a sufficient distance to form a gripping member. I Fig. 16, illustrates a gripping member 40, consisting of a collar having an annular concaved portion 41 adapted to receive the rounded surface of the head 2. Said collar 40 is also provided with a flange 42 which is of conical formation and forms the gripping member.

Figs. 17, 18 and 19, illustrate gripping members 45, 5.0 and 55, respectively, which are secured to the ends of the cylinders.

Said members are slightly larger in diameter. than the bearing surfaces of the head 2 which would normally rest upon the ground when the cylinderv is standing on its end, thus providing a broad and firm base for supporting the cylinder in an erect position and embodying therewith -the gripping members. I

- The gripping member 45, shown in Fig. 17, has an inwardly projecting flange 46 which forms the gripping member. Said flange 46 forms part of the cylindrical portion 47, which is secured to the end of the cylinder body 1. I

The form of gripping member shown in F ig. 18, consists of a collar 50, which is shown secured upon a cylinder having a convexed head 2. Said collar may be 14 illustrate a gripping memslightly larger in diameter than the body of the cylinder, .thusifgrming asubstantial base .for the cylinder, and the inwardly 19, consists of a disk secured upon the bottom surface of the cylinder head. Said disk is provided with a central opening and the inner edge of the disk forms the gripping means.

The gripping members 45, 50 and are shown provided with holes 48, 51, and 56, respectively, for the outlet of water, dirt or cinders which would otherwise accumulate within the gripping members.

Having thus described m invention I claim and'desire to secure by tters Patent;

1. A seamless drawn steel cylinder having a body portion and an integral drawn head closing one end of the cylinder, said head provided with a recess extending inwardly beyond the plane of the end of the body-portion, and a handle secured upon said head located entirely within said recess. 2. A seamles drawn steel cylinder having I a body portion and an inte gal drawn head closing one end of the cylinder, said head provided with a recess extending inwardly beyond the plane of the end .of the body portion, and an annular member secured upon said head located entirely within said recess forming a handle for-whiting the body portion.

3. A seamless drawn steel cylinder having a body portion with rounded end surfaces and an integral drawn head closing said body portion, said head having a concaved recess formed therein, a me er having a curved surface adapted'to be secured to said concaved surface of the head and said memher having an inwardly projecting flange forming a handle for lifting the cylinder.

In testimony whereof I aifix my signature.

JOSEPH A. STEINMETZ.
