To all 'whom t may concern:

Be it known that I, GEORGE Tnuivirii'rnn,

a citizen of the United States of America,

residing at Alliance, in thecountjT of Stark and State of'iOhio, have invented certain new and useful Improvements in Ice Picks, of which the `following is a specification.

This invention relates to certain new and useful improvements in ice picks and has particular reference to the provision of a resiliently mounted pick point or bladecarriedby a handle;

Thefprimary object of the invention resides in the provision of an ice pick wherein resiliently i application, and

appended claims.

a handle provided with an-elongated socket houses a pick point ycapable of being locked to the handle in a rigid condition, in either a projected or retracted position.

The invention further provides in an ice pick of the type above set forth the idea of completely housing the pick point when out of use to prevent injury or damage to adjacent objects.

With these general objects in view and others that will appear as the nature of the inventio'nis better understood, the same consists in ythe novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing, and pointed out in the ln the drawing forming a part of this in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is ya side elevational view of an ice pick constructed in accordance with the present' invention, with the pick point in its retracted housed position, i 'Figure 2 is a longitudinal sectional =view showing` the resiliently mounted pick point in arigid lposition slightly projected from the end of the handle device, for purposes of marking or scoring a block of ice, and showing the pick point by dotted lines in its extended position, j, n

Figure 3 is a cross sectional view `taken IIL-III of Figure 2, showing the pick point locked to a part of the handle,

Figure 4 is a side elevational view ofthe tubular member removed from the handle,

` `Figure 5 isa side elevational view of the Speeication of Letters Patent.

The specific construction of the tubular member 8 shown more clearly in Figs. 2 and 4 is longitudinally and diametrically slotted as at 4, to provide two substantially semi-circular side sections, as shown in Figure 3, that .carry at adjacent ends an integral annular collar 5 threadedover a portion of the length thereof as at 6. The edges of the slotted opening 4 are provided. with side notches 7, while similar notches 8 are formed in the side walls of said slots adjacent the threaded portion 6 of the thimble. A. sleeve member 9 open at each end, is internally threaded atv one end as at 10and carries outwardly directed, diametericallv opposite lugsll at the other end thereof, the sleeve 9 being inserted into the tubular member 3 with the lugs 11 sliding in the side slots 4 of the tubular member, the lugs 11 engaging the thimble 5 `to prevent complete passage of the sleeve through the tubuinto seid recesses and e tubular mit threaded `on the tbimble and having notches on one 10 edge thereoil to receive the sleeve lugs to move said luge into one of the recesses Jformed in the tubular member for holding the sleeve immovable relative to the tubular member.

In testimony whereof I affix my signature. 15
