Figures 6 and 7 are plan and sectional by brazing or byscrewing or other form of views respectively of the ground plate and its mechanical connection. The bracket is prolocking means. vided with a pair of horizontal pins or rivets Figure 8 shows the application of the inc which are fixed in the opposite walls therevention to a non-adjustable walking stick of and constitute the pivots for the wire loops 50 seat. or seat members 6, b. A tubular distance piece is preferably introduced onto each of these pivot pins between the eyes 12 of each loop, or alternatively the distance pieces may be cast solid with the bracket.

In order that the seat members when used as a handle shall be rigid with the support the bracket 0 is provided with a stop which may conveniently take the form. of a dividing wall 0 formed integrally with the bracket and extending across the same between the pivot pins so= as to: limit-the foldingmovement of the seat members in such a manner that when they are gripped together inthe position shown in Figure 5, they form. a.

handle which is quite rigid with the support.

\Vhere the improved stick is made adjustable in height, Figures 1 and 3, the lower end is provided with a tubular member 6& adapted to telescope within the support a, and to be locked in its adjusted position therein. For this purpose the locking means is preferably concealed within the interior of the telescoping members and, in the form shown, consists of a pin or detent d whichis mounted in a hole 0 in the inner telescopic tubular member of the stick from which it normally protrudes laterally under the influence of a spring" 7' concealed within the said member. The said pin is adapted to engage with any one of a longitudinal series of holes 9- formed for the purpose in. the outer telescopic member of the stick so as to prevent relative movement between the two telescoping members. In order to release the latter prior to. adyustment, all that isnecessary is to depress the outer protruding end of the pin (Z against the action of the; spring into its hole in the outer member when the stick can be extended or shortened, as desired,.the pin automatically snapping into. engagement with another of the holes 9 in the outer member and effectually locking the parts in the new position. The protrudin end of the pin is suitably chamfered or round d so that it is not necessary 1 to use a tool to force it right back before the stick can be adjusted.

The pin; may be spring mounted in any suitable manner, asby means of a blade spring. which, as shown in- FigureB, is loosely inserted in the open inner end of the inner telescopic member a and formed so as normally to n aintain the pin (l in. its operative position. Advantage may be taken of utilizing the same spring 7' to prevent, any tendency to rattle or free play between the telescopic members of the stick. For this purpose one end 7 of the spring may extend. beyond the open inner end of the innertelescopic memher and be so shaped asto press firmly against the. inside wallof the outer telescopic memher a in a, direction opposite to. the pressure exerted by the part carrying the pin. This effect is obtained. by bending the ends of the spring substantially in the manner shown.

Theimproved locking device is equally applicable where adjustment is made at the upper end of the stick, in which case the bracket 0 would be carried by the inner telescopic member (L The plate or disc h, which is normally carried by a boss 0 on the bracket 0 and when the stick is in. use is transferred to the ferrule a to prevent the latter sinking into soft ground, is removably secured in either of these two positions by means of a locking device which when the disc is: introduced onto the said boss or the ferrule automatically locks the same in posit-ion thereon. In its preferred form, the said locking device consi'sts of a blade spring 2' which loosely encircles-a boss h on the plateand isseeured theretosat its ends by a screw 70.. At a point diametrically opposite the screw the spring is provided. with an inwardly directed pin or peg Z which is adapted to enter a hole 129; in the said boss on the plate and to protrude therethrough into engagement with. an annular groove n in the ferrule 64 or lower end of the stick, Figure 3, or in the boss 0" on the bracket, Figure l. The action of the locking device is such that, normally the blade spring 2' holds the pin Z in: its operative 7 position so that when the plate is introduced into either of its two positions the pin is first pushed outwardly against the pressure of the springuntil it comes opposite the annular groove it when it automatically snaps home under the-influence of the spring and securely locks the plate in position. In order to remove the plate the spring 71 is compressed between the fingers along a diameter substantially at right angles to that containing the pin Z and screw 72 when it will be found. that the resulting distortion of the spring will cause the, said pin to move out of its operative position. Alternatively, the locking pin may be carried. by a bow-shaped spring embracing a portion only of the boss on the plate and having its ends returned onthemselves for a short distance and retained. in position between stops on the plate and the boss of the latter. The pin. is carried by the middle of the spring and operates in. the same way as above described, being released by pinching the ends of the spring against the boss of the plate which causes the middle part of the spring to move away from the boss and so withdraw the peg from engagement with the annular groove.

The bottom end of the stick or the ferrule a may be screw-threaded internally or otherwise formed to. receive an india-rubber pad '0. or a spike.

I claim:

1.. In a seat stick having a cane portion, a bracket mounted on the upper end. of said cane portion, a pair of anchoring pinsmounted in: said bracket and extendingparallel to each other, and a division plate rigid with said bracket and extending from end to end thereof parallel to, between, and equi-distant from, said anchoring pins respectively, the said bracket having sides respectively extending parallel to and adjacent the respeclive pins, in combination with a pair of resilient loop members respectively mounted on said pins to swing about the respective axes thereof, each said loop member being adapted to swing in an are not exceeding ninety degrees defined at one end by the division plate and at the other end by the edge of the respective cooperating side portion of the bracket.

2. In a seat stick having a cane portion, a bracket mounted on the upper end of said cane portion, a pair of anchoring pins mounted in said bracket and extending parallel to each other and a division plate extending from end to end of said bracket parallel to, between, and equi-distant from, said anchoring pins respectively, the sides of said bracket extending upwardly beyond a horizontal plane intersecting the axis of said pins in combination with a pair of resilient loop members respectively connected to said pins to respectively swing about the same, each said loop member being adapted to swing outward away from each other and to be within the interiors of said members and having its end portions bent inward toward each other so as to result in putting the end portions of the spring under compression and having the extreme end portions of the re spective ends of the spring in engagement with the respective telescopic members to eliminate play between said members.

In testimony whereof, I have signed my name to this specification at Coventry, England, this fifteenth day of February, 1930.
