ICE-PIQK SCABBARD.

Specification of Letters Patent. Patented Aug. 14E, 1917.

Application filed April 3, 1917. Serial No. 159,574.

To all whom it may concern: v

Be it known that I, JOHN B. MARTELLI, a subject of the King of Italy, residing at 537 East 83rd street, New York city, in the county of New York and State of New York, have invented new and useful Improvements in Ice-Pick Scabbards, of which the following is a specification.

This invention relates to ice picks, and more especially to the cases or sheaths in which the same are mounted; and the object of the invention is to produce a scabbard or protector of peculiar formation which will permit the escape of the water of condensa'tion gathering on the pick so that the latter will not become rusted and which so far as possible will protect the user from injury and the pick itself from dust and germs.

It is the purpose of the present invention to produce a scabbard of peculiar formation whereby the water of condensation will be permitted to escape and whereby the pick will be protected and the user will be protected from the pick, and in this connection l I employ a special form of fastening between the scabbard and the handle so that the parts may not accidentally become'detached but may be disconnected immediately when desired. y

Details are set forth in the following specification, reference being made to the accompanying drawings wherein 'z- Figure 1 is perspective view of this improved device in its simplest form.

Fig. 2 is a central longitudinal section showing the shape of the inner wall of the scabbard, and how all parts therein descend toward an outlet opening when the tool lies on a flat surface.

Fig. 3 is a fragmentary perspective of the inner end of a scabbard showing fasten ing means of slightly different form, and Fig. l is a perspective view of the handle portion of the device coacting therewith.

We are not concerned with the structure of the handle I-I-into which is inserted the blade or bodkin B, held therein by a ferrule F. The blade or pick proper tapers to a point P at its outer end, and the construction and use of ice-picks is too well known to need amplification.

Coming now to the present invention, the scabbard l is a hollow affair of suficient length to inclose the blade, externally round or oval as may be desired, closed and preferably rounded at its outer end 2, and provided With a bore?) which preferably tapers toward its inner endv where it fits closely around the blade at the point 4L. The bore alsor may taper toward the other end near the point 2, as best seen in Fig. 2, and the result is that the bore is larger at its midlength at about the point 5s Here its wall is pierced with two openings 6, and it will be observed that when the tool lies on a level surface indicated by the line 7, even though its inner end is canted up a little by the handle I-I, all portions of the interior of the scabbard descend slightly toward the open` ing 6. The result is that moisture on the blade B which condenses thereon or drips V therefrom, will -fall into the bore of the scabbard and will run out the opening 6to a large extent.

While the scabbard above described 'is obviously slipped over the blade when the latter is not in use,and possibly might be held with some friction thereon at the point 4, I prefer to provide fastening means between the hooks ll and the latter snap behind it and the parts are fastened together As shown as seen in Fig. 2. I would not have the hooks very decided, and therefore the scabbard may be. jerked out of position between them; but if they do too reliably engage the rib, they may be pressed apart by the fingers and the scabbard withdrawn.

In Figs. 3 and l is shown a slight amplicationof the idea for purposes which will be made plain. I-Iere the scabbard is flattened on opposite sides as indicated at 20, and on lines directly in line with the holes or openings 6, the attened portions or faces extending completely through the rib 12 which latter is therefore divided into two ribs, each extending around-perhaps onel0 whose front ends are hooked inward as at ll to engage the ribs on the scabbard, and in this case the jaws may be rigid if desired-in fact the entire handle could be stamped or cast from a rather' thick block of metal, and the tempered blade or bodkin may be inserted and welded or otherwise secured in place as desired. The scabbard is obviously connected with the hooks 1l by passing its flat faces 20 between their inner ends and then giving it a quarter revolution to bring its ribs l2 behind said hooks, and the parts are so disposed and proportioned that at this time the smaller inner end 4E of the bore of the scabbard lits rather closely around the larger inner end of the blade B. Having given the scabbard such partial rotation, the holes 6 are disposed opposite the liat faces of the handle I-I. Now when the tool is laid` aside, the flat handle will not stand on edge. In that position the axis of the scabbard would be so tilted that moisture within the same would run down into its point rather than escape through the openings 6. The purpose of flattening the handle is therefore to make the device lie as seen in F ig. 2, so that moisture may escape in the manner above described. Moreover a handle so constructed is somewhat cheaper than the average handle made of wood, but with respect to materials and proportions, and other details, I do not wish to be limited. The essential feature of this amplification of the idea is that, whereas the structure shown in Fig. l would permit the sca'bbard to be slipped onto the blade and left with the openings at the sides rather than the top and bottom, this structure requires that when the scabbard is latched to the handle the opening 6 must be vertical and moisture will escape.

What is claimed as new is l. The combination with an ice pick comprising a blade and a relatively flat handle; of a scabbard having two diametrically op- `Josite moisture-outlet openings and its bore eing larger adjacent said openings and tapering in both directions away from them, and fastening devices between the contiguous ends of the scabbard and handle so disposed axially of these elements as to be engaged when said outlet openings stand vertical, for the purpose set forth.

2. In an ice pick, the combination with a blade, a flattened handle to which its base is attached, and oppositely disposed jaws projecting from the inner' end of the side edges of the handle alongside the blade andy hooked inward at their forward extremities; of a scabbard rotatably and removably inclosing the blade and flattened at its inner end on opposite sides so as to pass between said hooks, its body having diametrically opposite moisture-outlet openings in line with said flattened portions of the scabbard, and ribs on the exterior of said inner end between the liattened portions', for the purpose set forth.
