WALKING -STICK G RAPPLE.

SPECIFICATION forming part of Letters Patent No. 465,222, dated December 15, 1891.

Application led September 28, 1891. Serial No. 407,049. (No model.) Patented in France March 26, 1891, No. 212,383; in Switzerland June 25, 1891, No. 4,105, and in England July 1, 1891, No. 11,219.

.To all whom it may concern.-

Be it known that I, KARL ALBERT EGON ULBRICHT, a Subj ect of the King of Saxony, and a resident of Taubenheim, near Meissen,

inthe Kingdom of Saxony, German Empire,

have invented certain newr and useful Improvements in Talking-Stick Grapples, (for l whichI have obtained patents in France, No. 212,383, dated March 2G, 1801; in England,

xo No. 11,219, dated July 1, 1891, and in Switzerland, No. 4,105, dated June 25, 1891,) of which the following is an exact specification.

This invention relates to a mechanism for conveniently grasping objects lying at some r 5 distance away, which mechanism may beattached to a Walking-stick or an umbrella or the like. By aid of anystick being furnished with the said mechanism one is enabled to pick up anything lying on the fioor Without zo -having to stoop down, which particularly will be found of great value on mountains, where stooping down frequently is dangerous. In order to make my invention perfectly clear, I refer to the accompanying drawings,

2 5 which illustrate a Walking-stick provided with the mechanism forming the object of the present invention.

Figure lis an elevation of the stick, wherein the grasping mechanism is opened ieady 3o to grasp. Fig. 2 is a section snowing the mechanism when closed.

The complete mechanism is concealed Within the interior of the stick, with the exception of the grasping-tongs a and b.

3 5 a is integral with the stick, and the other jaw b is hinged to the same by the pin c. When making use of the stick for walking, these tongs are closed upon another, like in Fig. 2. This closing is secured by the lever (l, which 4o has its fulcrum at e and is linked onto a connecting-rod g by the pin f. The connecting-rod g is on its rear end attached to the hinge-stock h', being hinged to the bars Zand m, which are linked to the tongs a and b in the manner of a toggle-joint. Of these bars m connects the stock 71, to the fixed jaw a and Z connects the same to the loose jaw Z). A small stay p is integral with the shell of the stick. A spiral spring b bears at one end 5o against the stay p and at the other against the hinge-block h', and thus tends continu- The jaw ously to open the tongs. It, however, being necessary to keep the tongs generally closed and only allow them to open out at times, the implement is provided with a locking device which firmly holds the jaws together. This locking device consists of a click o', which inside of the handle is pivoted to the sides of the same by a pin and is adapted to engage with the hook a', which may be riveted on or otherwise att-ached to the lever cl. The bar z is guided at 15,15', and t2 and is loosely pinned to the ond of the click 'l'. l5 y these means and by aid ofa spiral spring u, the click o' is continuously drawn toward the hook If now desired to use the implement, a slight pressure with the thumb on the knob if', sitting on thc end of the bar fu, will sul'iice to release the hook .e from the grasp of the click o', and, giving way to the tension 0f the spring b', the 7o connecting-r0d g moves toward the point of the stick. The legs of the toggle-joint Z m thereby stretch out and open the jaw b in the mannerillustrated by Fig. 1. lVhile holding the stick by the handle w the lever CZ Will lie also within the grasp of the fingers, which thus without difficulty may apply a slight pressure to the same lever d. This pressure is transmitted by the rod g and toggle-jointl m to the tongs a b, which firmly hold fast any 8o object coming within their reach. Having then taken the object away the tongs may again be closed by pressing the lever d so much that the hook .e be caught by the click r.

I particularly point out that all movable members are placed within the hollow of the stick, and therefore are not liable to be clogged by dirt. Care also has been taken to avoid friction as much as possible. In order to re lease the locking device arranged within the 9o handle of the stick, one only need apply a very slight pressure on the knob lu by the thumb, which generally is held close by When using the stick for walking. .By this slight pressure the tongs at once open out.

Another advantage may be mentioned. The implement is always ready for use, no protecting shell need be removed, nor screw nor any other part has to be disjointed beforehand. The appearance of the stick does not dilfer 10o from other walking-sticks. Nobody, in fact,

will take any notice of the parts which are not common with other sticks unless espeoially having his attention drawn thereto.

Having thus fully described the nature 0f my n said invention and in what manner the same 5 is to be performed, I declare that whatI desire to secure by Letters Patent of the United States is- In a stick made hollow, the lever d, arrangedwithin the handle, the toggle-joint Z h lm, linked to the fixed jaw aand the loose jaw b, the connecting-rod g, connecting the hingeblock h and the lever d, a spiral spring surrounding a portion of the rod g and bearing I on oneend against the hinge-block h and at the other against the stay p, in combination 15' with the looking device consisting of the bar v, adapted to slide within the handle w, and the click 1', linked to the bar 'u and adapted to engage with the hook z, attached to the lever, as for the purpose set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
