To all whom it may concern: 7

' Be it known that I, RICHARD H. COOKING, a citizen of the United States, residing at Salem, in the county of- Salem and State of New Jersey, have invented certain new and useful Improvements in J ar-Lifters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in jar lifters.

The object of this invention is to provide a lifter which may be easily and quickly applied to jars to remove the same from steamers, boilers or the like, thus obviating the necessity of removing the steamers,

boilers, or the like from the fire and allow ing the jars to cool before handling.

A further object of this invention is to provide a lifter designed to fit any make of jars and so constructed as to be easily secured around a jar to remove the same without fear of the operator being s'calded,

burnt or otherwise injured.

A still further ob ect of this invention is to provide a lifter of this character which will be simple, practical and comparatively inexpensive in construction and one that can be manufactured and sold at a comparatively low cost.

With these and other objects in view the invention consists in and arrangement of parts hereinafter 'more fully described'and pointed out in the claims hereto appended.

In the drawings:

Figure 1 is a view in perspective illustrating my. improved jar lifter as made in accordance with my invention.

Fig. 2 is a view illustrating a boiler, steamer or the like illustrating the manner in which the lifter is applied to jars of ordinary construction, and

Fig. 3 is a side elevation of my improved jar lifter applied to an improved jar.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

Referring more particularly to the drawings, the numeral 1 designates a steamer, boiler or the like in which is located a number of jars 2 of the usual construction and having my improved lifter 3 applied thereon.

the novel combination.

proved jar lifter comprises in its constructlon a shank 4 which is preferably My im circular in cross section and has secured on one of its ends a handle 4 of any suitable construction.

The shank 4 is provided near its free end with a transverse y extending opening 5 in which is journaled a bearing pin 6, which'is adapted to have secured thereon a lever7.

The lever 7 above mentioned is substantially lL-shaped and comprises a long member 8 and a short member 9.- The end of the long member 8 is bifurcated to provide a pair of'relatively spaced arms 8 and 9. The arms 8 and 9 are provided with alined transverse openings 10 which ,openings are adapted tosecure the arms to the opposite ends of the pin .6.

The arms 8 and 9' of the. lever 7 are a'rrangedon opposite sides of the shank 4 and the openings 10 of these arms are located in direct alinement with the opposite ends of the pin 6. The opposite ends of the pin 6 are secured in the openings. 10 thus securing the arms to the pin 6 and permitting the same to be moved therewith.

A pair of jaws 12 formed of flat sheet metal are provided with elongated substantially rectangular body portions 13 which have one of their ends t'apered as at 14. The tapered ends of each of the bodies 13 are bent, upwardly at right-angles to the bodies to provide attaching portions 15 which attaching portions are provided with spaced openings 16 which permit the jaw members to be secured to the shank 4 and the shorter member 9 of the lever 7 The free end of the shank 4 and the end of the shorter member 9 of the lever 7 have the attaching portions of the jaws 12 seeured thereto on the inner faces thereof by rivets 17 or any other suitable fastening means.

The inner opposed ends of the body portions 13 are concave as at 18 to permit the jaw members to conform to the configuration of various forms of jaws and thus by upward pressure on the handle the jaw members will be forced toward one another and the, jars firmly held between the jaws.

In operation:

The handle 4' is firmly grasped by the operator and the lifter is then in the position" as shown in Fig. 1. The lever? carrying one of the jaws 12 is then forced down into engagement with the jar. The jaws 12 have their concave portions in abutting enjaws of through said arms and gagement with the neck and the peripheral edges of the bodies are located under the screw threads of the ordinary type of jar or under the flangeA in the improved type of jars, by upward pressure on the handle 4 the weight of the jar will force the lever 7 toward the shank 4 thus the Jar is firmly held'between the two aws. To release the jar it is only necessary to place the same upon a support thus relieving the its-weight and the lifter may be readlly removed.

at is claimed is:

1. A jar lifter comprising a shank, a handle on one end of the shank, ajaw rigidly secured to the free end of the shank, a substantially. L-shaped lever, the terminal of the longer provide arms, said arms arranged on opposite sides of the shank, means extending shank for pivotally securing the lever thereto, and a jaw rigidly secured to the shorter end of the lever and the inner opposed edges of the jaws being concaved to firmly grasp a jar therebetween.

2.- A jar lifter comprising a shank circular in cross section, a handle on one end of the shank, said shank provided near its free endwith a transversely arranged opening, a bearing pin journaled in said opening, a

I substantially -L-shaped lever, the terminal of the longer end of said lever bifurcated to portions of the jars aws comprising body portions,

7 shank,

end of said lever bifurcated to (1 provide relatively spaced arms which are provided with openings, said arms arranged on opposite sides of the shank and connected to the opposite ends of the pin, and a pair of tapered attaching portions formed integrally with the ody portions and arranged at right angles portions rigidly 3. A jar lifter comprising a substantiall vertical shank, a handl e at one end of the shank, a aw at the opposite end of the an arm pivotally secured by one end to the shank intermediate the ends thereof, a epending shank formed on the free end of the arm, a jaw formed on the free end of the shank of the lever, said vertical shank RICHARD H.
