D. L. POTTER POLICE STICK Sept. 15, 1931.

Filed April 24. 1929 Patented Sept 15,

DUANE I. POTTER, OF DALTON, PENNSYLVANIA POLICE .s'r ic r Application filed April 24,

This invention relates to batons or policelnens sticks, and more particularly to the type which providemeans for preventing the stick from being wrested from the policemans grip.

The principal object is to provide a stick to be used by peace officers or policemen, whereby the stick may be used in subduing an unrulyprisoner, and at the same time, should lo the prisoner attempt to wrest the stick from the o'liicers grasp, theoflicer may, by exerting a slight pressure against-the rear end of the stick, cause blades to move outwardly from the stick so as to present a cutting edge to the prisoners grasping hand.

, Another object isto provide a stick which, under normal conditions, will present the appearance of an ordinary baton or police stick, and yet contains means for breaking the grasp of an unruly prisoner should he attempt to take the stick from the oflicer. The means are controlled by the pressure of the hand. I

The idea of having means in the striking part of the stick which will project therefrom so as to break the prisoners grasp should he attempt to wrest the stick from the ofiicer is old; but heretofore, the means for causing the projections to extend from the stick has not depended uponthe pressure exerted by the hand of the officer in gripping the stick. I

In the drawings:

Figure 1 is a perspective of the stick in 86 operation; 7 i

Figure 2' is a section taken along the line 22 of Figure 3;

Figure 3 is a side elevation;

Figure 4 is an end elevation of Figure 3;

Figure 5 is a section takenon the line 5-5 of Figure 3; and t Figure 6 is a perspective of the cutting bladeremoved from the stick.

Referring to the drawings, in which similar numerals designate like parts,

Numeral 1 refers to a police stick having cutting blades 2 in grooves 3, therear portion of the cutting edge 2 having gripping 59 members 4 curved outwardly from the rear 929; Serial no. 357,803.

portion of the stick 1. Intermediate the cutting edges 2 and-gripping members 4 are pivotal members 5 in the form of shoulders through which pivot pins 6 pass. The rear portions of the grooves 3 are cut away so as to'leave sufficient space between the gripping members and the bottom ofthe grooves to insert flat springs 7, which are held in place against the gripping members 4L by sleeves 8, into'which the springs 7 are inserted.

I As actually used, the blades 2 will be entirely below the striking surface of the stick 1 at all times, except in the event of the prisoner attempting to wrest the stick from the hands of the officer.

. It will be noted that the cutting blades 2 are'pivoted at 5, and that the handle portions 4 ofthe cutting blades 2 extend from the rear of the stick 1 at an upwardand downward angle, respectively. As'the stick is normally grasped, it will be impossible for the cutting blades 2 to be raised above the striking surface of the I stick 1. It is only upon the prisoner grasping the end of'the stick and pulling on the same and forcing the ofiicers and to the rear so as to encounter the grip ping members 4 that the cutting blades 2 will beforced' from the stick. These will bear against the grasping hand of the prisoner,

and force him to relinquish his grasp thereon. As soon as the officers hand is removed from the gripping members 4;, and the stick normally grasped, the cutting blades 2, due to the fiat springs 7, will return to their normal position below the striking surface of the stick 1.

It is obvious from this, that only through the intention of the oflicer will the blades 2 be extended, and then, there must be a pulling force on the front end of the stick and the oliicer must allow his hand to slide to the rear sufficiently to contact with the gripping members 4.

It is also apparent that due to the springs 7, the cutting blades 2 will normally be encased in the grooves 3 below the surface of the stick 1.

It is understood that alterations and substitutions may be made in the above disclosure shaft;

Within the scope of the claims Without afl'ecting the merits of this invention.

WVhat I claim is:

1. A police stick comprising a cutting member normally below the surface of the stick, a gripping member integral with said cutting member pivotally connected to said stick for projecting said cutting member, means for returning said cutting member to 7 its normal position.

a lever of the shaft, comprising a cutting member and a hand grip; and means for; holding the I cutting member normally Within the surface oftheIsha-ft. 7 c c r 3. In a police stick, the combination of a shaft having a longitudinal groove and a lever pivotedin the sha t, one end of the lever having a cutting edge adapted to be projected ,7 from the groove and the other-end having a hand grip for projecting the cutting edge.

1; 4. In a-police stick, the combination of a shafthaving a longitudinal groove; a lever p voted in the groove, having a cutting edge and a hand grip and a spring o mally holdifigfthe cutting edge Within the surface of the s a t.- i

5.. In a police stick, the combination of a shaft having a longitudinal groove; a lever pivoted in the groove, one end of which comprises a cutting member and the other end an outwardly extending hand grip and a spring adapted to hold'the cutting member Within the surface of the-shaft.

,6, In a police stick, the combination of a shaft having longitudinal grooves; a lever pivoted-in each, groove, each lever compris 'ing a; cutting member and a hand grip; and springs adapted to hold theoutting members ithin the. surface of. the shaft... 1
