This invention relates to improvements in ice picks of the type shown in United States Patents Nos; 1,008,734, dated November 13, '1911; No. 1,701,771, granted February 12, 1939, and 1,768,035

It is well known that waiters in dining carsl and porters on trains are often required to prepare drinks containing ice and for thispurpose it is necessary for them to be equipped with ice picks to enable themv to break ice into properly shaped pieces. p

An ice pick must be. of quite strong and rugged construction and must have a sharp point in order to penetrate the ice and produce the desired l5 cleavage.

Waiter-s and porters on trains and in i other `places nd it a great convenience to carry an ice pick so that it can be `available whenever needed. If the pick is of the ordinary construction in which the' handle is firmly secured to one end of the pick, such an instrument is dangerous to carry and frequently causes injury and damage'.

The above mentioned jdifliculties have `been .recognized by others-as evidenced by the patents above identied, and in orderitoovercome such dimculties, these patentees have shownpick constructions in which the pick vpoint isreciprocable with respect to the handle so that it may be Withdrawn into the .latter a suflicient distance to cover the sharpspoint, and thereby make. the ice .pick harmless and suitablefor carrying in the pocket. t

AVIt is the object of this invention to produce a new and improved construction of ice pick which shall make it especially well adapted for the `purpose under consideration and `which results in a substantial and dependable tool that can be manufactured at a reasonable cost and designed insuch away as to make it especially well adapted for carrying in the pocket as 'above pointed out.

The construction in which the present invention resides has been illustrated in theacccmpanying drawingto which referencewill now be made, vand in which: i

Figure 1 is alongitudinal'section throughan ice pick construction in accordance with the present invention and lshows the ice pick extended in operative position;

Figure 2 is a section taken on line 2 2, Figure 1, and shows kthe relationship of thelatching member to the `other parts of the device;

Figure 3 shows the ice pick in collapsed position; and

Figure 4 is a fragmentary section showing slightly modiiied construction.

,In t'hedra-wing` reference numeral s designates ahandlewhich may be made cf wood 0r any other suitable material and this is provided with an axially'extending bore 6 of circular cross section. This bore terminates within the handle and the 5 lbottom has been designated by reference numeral 'lp Secured to the end of the handle through lshaped partition i2 that is provided with a cylindrical flange it and with a central opening le. The partition is of such size `that it fits the inside of the ferrule 8 quite snugly and the flange 20 i3 spaces the two parts so as to provide a chamber, the purpose of which will hereinafter appear. The ferrule 8 and the flange i3 are both provided with circumferentially extending openings i5 for the reception of a latching member l5. This l25 latching member is preferably made from resilient materials, such as spring brass or steel and has a straight portion projecting through the openings l5 and extending inwardly in close proximity to the outer surface of the partition. The latch- 1- 30 V ing member has a straight portion l1 that is accessible from the outside and which terminates in an end I8 which is provided 'with openings'for 'thereception of'securing screws'or pinsy I9. The

latchingmemberhasa'circular opening 2l! of the "35 same diameter as opening.y Ill. The inner Vportion lof opening f20hasa narrow notch 2| that'. tapers inwardly in the manner shown inFig-ure `2. The

`inner end of Vtheicenpickll is Yprovided with a lcylindrical head 22 of substantially the sameigo diameter as thebore 6, being slightly smaller than the ,lattert so as to Apermitthe parts to.` slide in'the'bore. The outer end of the cylindrical =member mayl be Vflat or may be somewhat` conical Vas indicated by reference numeral 2li. The '45 vdiameter'ofthe head 22 is larger than opening Nl withv the result that it limits the outward movement of4 the pick, Attached to or formed integral with thepick is a collar '24 that is Apreferably circular:` and of such diameter that it can pass 5() throughlthe vopening lli. The space between the collar andthe end of the head 22 is such that when the pick is iii-'extended position thelatching member- IS can be moved intoposition between the inner end of the collar and the partition so 55 as to latch the ice pick in extended position, all in a manner shown quite clearly in Figure 1.

When the parts are in latched position, they occupy the position shown in Figures 1 and 2, from which it can be seen that a portion of the latching member is positioned in the groove between the head 22 and the collar 24. With the parts as shown in Figure 1, the ice pick is ready for use and can be used as an ordinary tool of this kind. After the pick has been used, the operator can press inwardly on the handle I 1, thereby moving the latching member inwardly until the collar 24 passes through the openingv 2Q, after which itwill pass through opening |11 and the parts will then occupy the position shown in Figure 3. The pick is made of such length that when the parts are collapsed the tapered point of the pick will engage in the tapered notch 2l and this will hold the pick from accidental outward movement.

In Figure 4 a slightly modified form has been shown in which the inner surface of the collar 24 is tapered as well as the outer end of the head 22. Thismakes it possible to obtain a slight clamping action, if this should be deemed advisable.

From the above description it will be evident that I have produced a simple ice pick of substantial construction that can be easily collapsed into such a position that it will be suitable for carrying in the pocket and which can be readily extended by a simple inward movement of the latching member and a corresponding outward movement of the pick member I l.

The cap and the partition are of such designthat they can be formed quickly and cheaply by any suitable tool and the latching member can also be formed by a suitable forming tool where- Vflore the cost of manufacture can be reduced to a minimum.

The latch IB has been shown as provided with a notch 2l which engages the point of the pick when the latter is in retracted position; this prevents the pick from being accidentally projected and holds it from sidewise movement. It is evident, however, that the pick can be made slightly shorter and the notch 2| omitted; with this construction the point of the pick would engage the inner surface of the latch and the latter would prevent the pick from moving outwardly.

Having described the invention what is claimed as new is:

1. A collapsible ice pick comprising in combination, a handle having a longitudinal bore extending. inwardly from one end thereof, a cap attached to the end of the handle having the bore opening, the closed. end of the cap having an opening in axial alignment with the bore, a transverse partition positioned between the end of the cap and the end of the handle, means for spacing the partition from the inner surface of the cap to form a chamber, said partition having an opening in axial alignment with the bore, said opening being of smaller diameter than the bore, an ice pick having one end providedwith a cylindrical enlargement which is slidable in the bore, the pick having an annular flange on the front of the cylindrical enlargement and spaced from the latter a distance greater than the thickness of the partition to form a groove, and a latch device carried by the handle for movement into and out of the groove, said latching device being positioned on the outside of the partition.
