1 Claim.

The present invention relates to that classification of tools and implements expressly designed and utilized for loosening and extracting fibrous, rubber and equivalent packing material from stuffing boxes.

As the preceding general statement of the invention implies, I am aware that various forms and styles of implements have heretofore been patented, marketed and otherwise utilized to extract packing materials from stuffing boxes.

- Manifestly, therefore, my primary aim is to generally improve upon known devices of this classification by providing What is believed to be an improved and novel structure, this being comparativelysimple, economical, reliable, and susceptible of adequate use in places where the pack ing material is not readily accessible for easy dislodgment.

Stated more specifically, the preferred embodiment of the invention is characterized by a lever unit of semi-rigid form, this having associated with the packing extraction .end a flexible element arranged to appreciably augment the combined leverage of the device, as a unit, to promote more successful usage.

. Other features and advantages will become more readily apparent from the following description and accompanying illustrative drawmg.

In the drawing, wherein like numerals are employed to designate like parts throughout the views,

Figure l is a perspective view showing one embodiment of the invention. 1

Figure 2 is a perspective view showing a slight modification in construction and Figure 3 is a view showing one use of the device.

Referring now to the drawing by distinguishing reference numerals, it will be observed that the lever unit proper is-denoted by the numeral 3. This is formed from a flat bar of steel tapered from the upper toward the lower end and of just suflicient resiliency to adapt it to the particular purposes intended. That is to say, the steel is ofsuch tensile strength and elasticity as to flex laterally in the direction of the flat sides and to allow slight axial twisting. In prior devices with which I am familiar it seems cussimilar device usable as a temporary handle to expedite manipulating the lever. The relatively wide lower end portion is provided on one longitudinal edge with an outstanding apertured lug 5 which serves as an anchoring or attaching 5 eye for a flexible element employable in conjunction with a lever to fortify and multiply the leverage'of the device as a whole. By having the structure somewhat widened at the point 6, sufficient stability is provided. Beyond this point 6 the metal is shaped to provide a curvate extension I which may be described as a hook, and this terminates in a lance-like penetrating and extracting point 8. In Figure 1 the soing and then extracting fibrous packing and equivalent material from a stuffing box. As tools for this same purpose'have been heretofore patented and are well known in general, it is unnecessary to delve at length into the need for the same and the precise method of use. It is sufficient to point out that the spear-like hook or point is embedded in the packing andvthis is accomplished through the aid of the chain or flexible element which serves, at the time, to embed the hook and thereafter hold it against accidental slippage. The great flexibility of the chain and the corresponding flexibility of the lever permits the two parts to be positioned in proper relationship to: each other to obtain the desired embedding and pulling and leverage producing action. In efiect we thus have a chain functioning as a lever and the main lever 3 functioning in an obvious manner, the two serving collectively to promote effective and dependable results. Hence, in a sense, we have a flexible main lever 3 and an auxiliary companion and more highly flexible lever 9.

In Figure 3 of the drawing, one practical use of the device is shown. No. 14 designates a stuffing box through which runs rod l2. Superposed layers of packing l3 are held in the stufiing box l4 and surround the rod l2. To extract the packing I3 the hook I is worked partially into the packing I3 then chain 9 is wrapped about the rod I2 and acts to hold the lever 3 from slipping while thehook 1 is further rotated under the packing l3 then the chain 9 is used to pull the hook I upwardly while' the lever 3 is held in the other hand to prevent it from turning and exiting through the same aperture it made when entering.

It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be 0 understood that minor changes comingv within the field of invention claimed may be resorted to if desired.

I claim: a

A packing extracting tool comprising a longitudinally elongated resilient lever, a curvate tapered hook integrally formed on the lower end of said lever and extending laterally of said lever, a handle loop formed on the upper end of said lever, and a chain anchored at one end to said lever adjacent said. hook on the side of said lever directly above said hook, whereby flexing of said lever aids in embedding said hook in said packing, and a pull on said chain aids in extracting said pacldng.
