ICE-PICK.

SP EOIFICATION forming part of Letters Patent No. 537,021, dated April 9, 1895.

Application filed July 30, 1894. Serial No. 519,043. (No model.)

To all whom it may concern.-

Be it known that we, CORNELIUS B. DARLING, WILLIAM T. MANN, and ROLLA R. DARLING, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Ice-Picks; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to ice picks, and the object of the invention is to produce a combined pick and hammer with a guard for the pick to prevent the scattering of bits of ice, all substantially as shown and described and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a plan elevation of the pick, elongated as it appears in readiness to deliver a blow, and Fig. 2 is a vertical central sectional elevation thereof as it appears when a blow on the stem of the pick is being delivered.

The device as shown consists of three parts, comprising the stem A, the head B and the shield or guard O. The stem or pickproper has a sharpened point=2= and a shoulder orppcjectiwpf any su it a e k.ind and proportion to top hoth ways,,,th11s preventing the stem from being drawn out in its upward or outward movements and the shield G from coming below a certain point on said stem. The stem further has a small head or projection l of its own at its top by which it is confined in the hammer head B, and the top of head 4- is flat so as to receive a uniform blow from the head B.

The head B has an elongated portion or neck -5-- with aspace of sufficient length to give such rise andfall to the head that it can be made to serve as a hammer to drive the pick into the ice. This space may be, say,

' two inches in a full sized pick or somewhat more or less will suffice. In the present construction we show a threaded plug 7- closing the upper end of the chamber -6 within the head and neck B, and the impact of the blow or stroke of the head upon the pick stem is taken by this plug. We might of course form the head solid where the plug 7-- is now inserted and depend on closing the lower end This shield.

to practically drive the pick into the ice where the initial stroke or blow is delivered. Without some such means of confining and centering the pick the point will strike here and there and seldom twice at the same place, and

thus a great deal of ice is chipped off and wasted which would not occur if the picking occurred at the same point exactly blow after blow. By this construction the pick point is set where it is wanted and held there by grasping the neck of the shield close to the back thereof. Then the hammer head B is drawn back and forth by the other hand and the pick is driven into the ice very much the same as a nail is driven into wood. Very little chipping off of ice occurs when this method of driving takes place and what does occur is caught by the shield, and by reason of driving the pick straight ahead atone point the ice is forced to speedily yield and split at the place and in the manner desired. Usually a few blows suffice to do the work.

The pick herein described is adapted to be used in three distinctly different ways:

First, by setting the cup or bell with its even edge upon a block of ice and grasping the neck of the bell between the thumb and tore finger, the bell can be carried across a block while the pick is being operated, and thus channeling the ice in order to split a piece very much the same as is now done by striking a sharp instrument like a hatchet into the ice for the same purpose; but with this pick there is no ice cast off because the bell confines whatever chips may be made and they remain on the block and are not wasted. Then, to split the ice the bell may be held in a given position and the pick be driven in sufliciently to do the splitting.

Secondly, if it be desired to use the pick the same as an old fashioned pick is used it is only necessary to draw the head and the bell together and grasp the two with the fingers around the neck of both with the thumb upon the hammer, and then pick just the same as if the bell and the hammer were one.

Thirdly, if one has a small piece of ice which he desires to break in the hand, the other hand will grasp the pick about the neck of the bell and around the stem of the pick and use the hammer as a hammer just the same as if it were nothing more than a hammer and did not have the means for picking.

Having thus described our invention, What we claim is- As a new article of manufacture, an ice pick consisting of a bell-shaped cup having a smooth edge to contact with the ice and an upwardly extending neck projecting from its top, a pick extending through said cup and neck and adapted to slide thereon, and formed with a stop or projection -3- and a hammer on the upper end of said pick having a neck and an elongated chamber in which the upper end of the pick is confined and operates, substantially as set forth.

Witness our hands to the foregoing specification this 14th day of July, 189i.
