Fig. 3 is a side elevation similar to Fig. 1, but showing the claws in closed. position. Fig. 4' is an end view of'the same. Fig. 5 is a cross section on the line a--a of Figs. 1 and 3. Fig. 6 is a 65 view showing how the open claws are engaged with the packing preparatory to the operation of the stems to close the claws in the material. Fig. 7 is a similar view showing the claws in closed position in the ma- 7.,0 terial with a firm hold thereon.

My improved device or tool comprises two stems 1 and 2, constructed preferably of heavy steel wire, which extend side by side for some distance, their rear portions being '15 separated to form a loop or handle 3, the sides of which are connected together at the end of the handle in the form of a spring coil 4." This structure may be conveniently formed from single piece of wire, which is 80 bent around on itself at its middle to form the coil 4 and the loop or handle 3, the two free ends of the wire being brought together to extend side by side to form thesterns 1 and 2. Near their extremities the stems at 85 their free ends are bent outwardly from each other to leave a space 5 between them, and the ends of the stems are offset laterally in opposite directions and pointed, so as to constitute in effect claws 6, 6, which are curved $0 in opposite directions, as shown in Figs. 2 and 4, and which are extended obliquely or at an inclination with respect to the stems, as shown in Figs. 1 and 3, thus giving to the claws a spiral form. The stems where 95 they extend'side by sideare closely but loosely encircled by a flattened sleeve or collar 7, which serves to maintain the stems closely side by side, but permits them to'be rotated or turned on their individual axes 16 relatively to each other and to the sleeve. The claw ends.6, 5, are extended in opposite directions relatively to each other, an by the turning motion of the stems, which is effected by twisting the looped handle, the 105 claws will be rotated or moved relatively to each other in the same direction and on axes coincident with the longitudinal axes of the stems, the twisting of the handle to the left,

To all whom it may concern Be it known that 1, JOHN H. LEEK, a citizen of the United States, residing at Brooklyn,'in the county of Kings and State of New York, have invented certain new and useful Improvements in Tools for Removing Packing and other 'Material, of which the following is a specification, reference being bad therein to the accompanying drawing.

The object of this invention is to provide a device or tool for dislodging or removing objects or material, such for instance as piston, gland and like packings, which pack- 1 ings in use become tightly embedded in the parts to which they are a lied, and which it is necessary to remove rom time to time for renewal, repairs and other purposes. Such packings in use being subjected con- 20 stantly to steam or fluid pressure or like conditions, harden and become very tightly seated, and their removal is attended with great difliculty,

-' My invention is directed particularly to the provision of a tool which may be operated to take firm hold on the packing or other material to be removed, and by which their removal may be effected with certainty and despatch.

In its more comprehensive scope my invention consists of a tool comprising a plurality of claws or fingers suita ly supported and adapted to be turned relatively to each other in such manner that they may be engaged firmly with the packing or other material to be dislodged, with the result that by pulling on these claws the material may be. removed.

In its more specific embodiment the claws- 40 or fingers are formed on the ends of stems, from which they extend in opposite directions and are curved or spirally formed, the stems beingextended side by side and adapted to be turned relatively to each other around their longitudinal axes, with the result that the claw lingers will enter the material with a screw-like motion and will come together in the material and take a firm hold thereon, so that by pulling on the stems, the material or packing may e readily removed. By the turning of the stems relatively to each other as described, the claw fingers will be opened or closed, according to the direction of movement, and the invention further consists in means for in Fig 3, operating to open the claws to the 58 the material with a screwing motion and hold is secured on the material and the latas well as an individual relative rotation ty and the minimum expenditure of force.
