July 12, 1938. H. B. RING SKI POLES AND HIKING STI CKS Filed NOV. 27, 1936 INVENTOR. HAROLD 5. RING. MM

ATTORNEY.

Patented July 12, 1938 UNITED STATES PATENT ori-lcs 9 Claims.

rIhis invention relates to new and useful improvements in ski-poles, hiking sticks, and the like, and it has for its special purpose to provide a ski-pole with an entirely novel and removable ring member or' disk mounted thereon, in such a manner that said ski-pole may easily and quickly be converted into a useful hiking stick.

Another object of the invention is to the effect that the said ring member or disk, in my new ski-pole may be replaced by a group of elastic p to leather or rubber fingers embodying a `springy steel core, and radiating from the pole to form a star-shaped bearing surface, to which I shall hereinafter refer as ng-erspread.

In skiing, especially downhill, a danger is always present, when using the hitherto common ringformed disk, which is likely to be caught in branches, rocks, etc., thereby causing the skier to take an unnecessary spill, this danger is eliminated by the usey of my present invention.

A further object of my said invention, as far as it relates to the fingerspread, is that the latter will readily shed the snow which is likely to accumulate thereon, this feature is of great importance, especially in a cross country ski race.

Still another advantage of my novel fingerspread lies in the spring action thereof, which feature is quite important, especially for a longer race, where every ounce of energy and strength comit.

Another advantageous feature relative to my new ski-pole `is the point protector, which serves several purposes;thus when poles are carried on trains, etc., and not in use, the snap-on rubber protector will protect fioors, and rugs from being scratched, or spoiled by said sharpV points, and will at the same time protect the points from being damaged on hard concrete roads in case the pole is used as a hiking stick.

Of other advantageous features may be mentioned, the special arrangement of the straps so that no right or left hand pole distinction is necessary; further the possibility of removing or replacing said straps, if desired; and still further the rubber knob, which tends to avoid accidents, when the skier takes a spill at a high speed; and finally the insertion of a Wooden core in the pole, which makes the latter practically unbreakable.

With the above and other objects in View, this invention consists of the nove-l features of construction, combination and arrangement of parts,

lhereinafter.fully described, claimed and illus- -such a manner as torleave a short distance 20 trated in the accompanying drawing forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure l is a side elevational view ofmy new 5 Ringomatic pole used as a ski-pole.

Figure 2 is a top plan View of the fingerspread; while Figure 3 is a transverse sectional view on the line 3-3 in Figure 2; and lv10 Figure 4 is an enlarged detail sectional View similar to Figure 3, before the finger is pressed into its final shape.

Figure 5 is a longitudinal sectional View through the handle; and 15 Figure 6 is a transverse sectional view of the same. l

Figure 7 is an elevational View of the lower end of the pole, showing the latter converted into a hiking stick. 120 Figure 8 is an elevational view of the point protector, showing the latter applied to the end of a pole.

Figure 9 is a top plan view of said point protector. `25

Referring more particularly to the drawing, l0 indicates a pole consisting of a metal tube Il, a ngerspread l2, a steel point I3, an enlarged portion M, servingl as a handle, a strap I5 secured to said handle, a somewhat ball-shaped .30 knobmember I6, serving as a protecting means against accidents, and a point protector, shown in the Figures 8 and 9.

The metal tube il, which preferably is made of a strong aluminum alloy, noncorroding and 135 nontarnishing, consists of two parts, that is, an upper, and as to length variable section l1, and a lower short section I8, of a standard length; said sections are held together by a nipple I9 in `40 between said sections, sufficient fo'r the insertion of the iingerspread between the latter.

The metal tube is except for small portions thereof, as later will be described, filled with a wooden core 22, thereby making this new pole practically unbreakable.

A steel point 2t is screwed into the lower and inside threaded portion 23 of the lower portion, or section lil. Said steel point is secured against unscrewing itself during the daily use of th-e 1.50 pole, by means of a lockspring 25, which actuates the steel point 24, as it has one end 26 thereof secured to the wooden core 22.

A similar lockspring arrangement will be seen in Figure 3,` where the nipple i,9,which by means ,55

of small pins, or the like, is made an integral rpart of the lower tube I8, is actuated by the lockspring 21.

As hereinbefore mentioned, the pole also serves the purpose of a hiking or walking stick, and naturally the ngerspread may easily be removed from the said pole by unscrewing the lower part I3, and removing said ngerspread, whereupon said part I8 is again replaced upon the pole, as may be seen in Figure '7.

A portion of the pole may for this reason be conveniently flattened to fit the same wrench, which may be used inthe removal of the point, as seen at 28 in Figure 1.

Two recesses 29 and 29A are arranged in the hexagonal part 3D of the point 24, and adapted to receive and secure on the latter two lugs 3| and 3I of a U-shaped spring 32 embodied in a rubber protector 33; the latter being provided with a central depression 4I therein to accommodate the point proper of the member 24.

By forcing the rubber protector upward, the spring will slide on the circular portion 34 of the point 24 and snap into the recesses 29 and 29. In removing said protector by turning the latter the lugs 3| and 3I will slide out of the recesses 29 and 29 and the V- shaped cuts 35 and 35 will engage the ridge 36 of the hexagonal part of the point, forming a guide for said protector in the removal of the same.

Figure shows clearly the construction of the handle. Thus a larger tube v31 with an inwardly bent lower portion 38 rests in a small recess 39 formed in the tube I1. A metal ring or washer 40 is arranged near the top as a support for the outer tube, and between said tubes a strap I5 is inserted as will-especially be seen in the Figures 5 and 6. A slot 42 is provided in said outer tube above the ring 40. A leather cover 43 ts snugly around the outer tube as a protection for the hands, especially in cold weather.

The construction of the knob I6 may especially be seen in Figure 5. Said knob is provided with a cylindrical cut-out portion 44 at the bottom thereof; while a metal plate 46 with a threaded pin 41 forming an integral part therewith, is forced into said recessed opening and secured to the same by means of rubber cement, or the like, as indicated at 48. Small slotted portions 49 in the plate and extending into the rubber cement secure a perfect binding of the parts. A rubber washer 50 is made to cover the plate.

A lockspring arrangement similar to those hereinbefore described may also here be employed. The flanges 5I of the knob will then,

when applied, as seen in the Figure 5, cover the edges of the pole, as a protection against accidents.

The construction of the iingerspread is shown in Figure 4. Three springs 52, 53, and 54 of different lengths are covered and secured together by elastic tape, or the like, indicated by 55, and these springs are in turn inserted into a rubber or leather cover 56. The six units, thus described, form one fingerspread, as will especially be seen in Figure 2. Said fingers are placed between two metal plates 51 and 58, and then pressed into the shape shown in the transverse section in Figure 3. Rivets 59 one for each finger will firmly hold said fingers in place, While a metal lug 60, in addition, guards said iingerspread against displacement.

It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown and described herein, within the scope of the appended claims, without departing from the spirit of the invention, and I do not therefore wish to limit myself to the exact construction and arrangement hereinbefore disclosed.
