1.111; i HANDLE.

Application filed February 23, 1924. SeralNo. 694,753.

To all whom 'it may Gomera:

.Be it known that I, LEO F. CAnnoLL, a

citizen of the United States, residing at Chicago, in the 'county of Cook and State of Illinois, have invented new and useful Improvements in I-Iandles, of which the following is a specification.

This invention relates to storage batteries, and more part-icularly to the boxes in which they are encased. Since their' contents are heavy, such boxes are strongly constructed, and being frequently handled, requirc that the supporting strapsV or handles be sufficiently strong and firmly attached.

It is one of the objects of the present invention to provide a handle for the above purpose which is of one piece and requires no extra parts, special tools or marked alteration of the battery box in its application.

Another object of the invention is to provide a handle of this kind which firmly engages the wall of the battery box without weakening the same.

A further object of the invention is to provide aliandle which acquires an inherent tension when fitted, which makes it selfretaining and assures a permanent grip on the battery box.

With the above objects in view, a more detailed description of the invention is to follow, attention being directed to the accompanying drawing, in which- Figure 1 is an edge view of the handle shown as applied to one end of a battery box in section;

Figure 2 is an elevation of the handle in readiness to be applied to the battery box; and

4Figure 3 is a similar view showing the handle secured to the box in readiness for Referring specifically to the .drawing, 5`

denotes the handle, which is in the form of an arch and made from a length of wire rod. The two shanks 6 beyond the head portion are substantially parallel, .and are medially bowed, as shown at 7, to a slight but readily perceptible degree. VThe crown of each bowed section is cut with a series of trans've'rse teeth 8; and the outer surface of each shank 6, beyond the bowed section is similarlycut, as shown at 9. The teeth are in the nature of pointed spurs, directed toward the head portion of the handle. l

In applying the handle to a typical battery box 10, which is made with thick hardwood walls, two holes 11 are drilled in each end wall 12, these being spaced to correspond with the spacing of the handle shanks 6, and of a bore slightly greater than the diameter of the handle stock. A hammer is then applied to the head portion of the handle to drive the shanks down into the holes 11 as fully as they will. go. The handle is now ready for use with the weighted box. The action-in causing the handle to become secured to the box is as follows: As the shanks 6 sink into the holes 11 with each blow of the hammer, the series of teeth 8 and 9 fill the holes, so that there is no play notwithstanding the somewhat greater bore thereof as compared with the diameter of the shanks 6. At the same time, however, the shanks, which are of spring metal, receive a straightening tension, due to the straight course of the holes, this tension causing the series of teeth 8 and 9 to sink into the walls of each bore when the handle is driven home. The shanks .are practi- 'cally straight now, but it will be obvious that they will continue to be under tension, forcing the series of teeth 8 and 9 to engage the wall of the box with a powerful grip.

While the use of a spurred shank may not be new as securing a gripv within a solid object, I do claim 4as novel the provision of a bowed or sinuous shank in combination with spurs whereby the latter are force'd to embed themselves in the object by force of lateral tension in the shank.

It will thus be apparent that the novel handle forms' a strong and durable support for battery boxes without the use of extra parts or fastening devices. The holes drilled in the box-ends will not weaken the latter. The device need not be limited to battery boxes, but may be applied with equal facility to other boxes or containers; also various changes or refinements may be madein the construction or design of the article without departing from the spirit and scope ofthe invention.
