COASTER TOY Filed Jan. 3, 1933 INVENTOR Max He/dmah ATTORNEYS the angle of inclination Patented Dec. 25 1934 UNITED STATES PATENT OFFICE ooAsTER 'roY Max Heldman, Birmingham, Ala. I Application ,January'S, 1933,'Serial No. 649,944 i 1 Claims. ((31. 298 182).
.My invention relates to a coaster stick for use i when coasting on roller skates and the like.
More particularly, my invention consists in a stick or staff having adjustably mounted thereon a small, light seat and having at or near its lower end a roller support which normally runs in contact with the ground but which has associated therewith a ground engaging drag brake element adapted to be applied merely byvafying of the coaster stick to the ground. I l 1 Q More particularly, my invention'contemplates mounting on the lower end of. the coaster stick, in juxtaposition to the roller support, an annular brake shoe which isso mounted that it can be turned about the stick thereby to present different faces for wear and which preferably is so disposed and of such shape that when the forward end of the stick is raised theshoe'will be brought into contact with thefground so'as to serve as a drag braking means. i i
My invention contemplates, as its preferred arrangement, the use of a pair of rollers mounted on a clamp frame adapted for attachment to the stick near the end brake shoe; As an alternative arrangement, a single caster roller can be mounted at the lower end of the stick and the brake element in the form of a' ring will then be'set in advance of it. In either case, by changing'the normal riding angle of the coasterstick its brake .holes 23 so that an attaching bolt or rivet 24 can be passed through one of these pairs and through can be brought into engagement withthe-ground and thus applied. 1 j
1 My invention further comprises the novel details of construction and arrangements of *parts which, i their preferred embodiment only, are illustrated in the accompanying drawing which forms a part of this specification, and in which Fig. 1 is a side view showing the coaster stick toy in its preferred form with its drag brake unapplied; V
Fig. 2 is an enlarged view of the lower end of the stick showing the brake applied;
. Fig. 3 is a sectional view taken on the line III-III of Fig. 2;
Fig. 4 is an enlargedside ,view of the coaster stick seat;
Figs. 5 and 6 are'sectional views on the lines V-V and VI+-VI respectively of Fig. 4;
Fig. 7 is a view similar to Fig. 2 of a modified form of my invention using a single end caster wheel and an adjustable brake ring.
Similar reference numerals refer to similar parts throughout the drawing.
In the embodiment of my invention illustrated in Figs. 1 to 6, I show the toy as comprising a coaster stick or rod 10, preferably a cylindrical wooden stair such as is used for tool handles,
and-near itslowerend I apply a mounting bracket for the roller support which comprises a pair of wheels 11, preferably mounted on ball bearings on anaxle or bearing bolt 12 having a bolt head 13 atone end and a nutll screwed on its other end and serving to hold the wheelsassembled with an interposed spacer sleeve 15 and end washers 16. -'The bracket comprises a loop ring 17 which partly surrounds the stick with parallel legs that receive a clamp bolt 18 beyond which the bracket legs are bent outwardly at 19 and downwardly at nut is applied to the bolt 18 it will engage a lower stick and to the sleeve15 on the roller assembly.
By removing the nut 14 on the wheel assembly bolt 12 the adjacent'wheel 11 can be removed, giving convenient access for the screw driver to "tighten the bolt 18.
' the roller element as above described is clamped to the stick near its lower end, leaving suificient space beyond it on the stick to receive the collar. 21 on the shoe 22. y
The collar has a plurality of pairs of aligning ahole bored through the stick thereby to mount the brake shoe on the lower end of the stick. By removing the bolt 24 and turning the brake shoe "as it wears new surfaces can be presented until the shoe is worn out. The brake shoe may be made of a metal casting or of any tough durable material suitable, by engagement with the pavement or ground, to give suflicient wear as a drag brake element.
I adjustably mount on the stick a seat of small light construction comprising the seat portion proper 25 having its edges rounded and terminating at'its forward end in a pair of curved clamp arms 26 and 27 which surround the stick and have interlocking tongues which when interlocked form a slip ring surrounding the stick. The seat is braced by a clamp strap comprising a center loop 28 which partly surrounds the stick and terminates in upwardly extending divergent legs 29 that have out-turned top flanges that are riveted or spot welded to the under side of the seat near its marginal side edges. A clamp nut and bolt 30 is inserted through the portions 29 ell) and tightened to rigidly clamp the seat in position on the stick.
It will be apparent that the seat can be adjusted along the stick tosuit the height of the child and, having clamped the brake shoe and roller support on the stick the toy is ready for the use indicated in Fig. 1, which shows a child coasting freely on the coaster stick and skates 31. Fig. 2 shows the inclination of the stick relative to the ground raised sufiiciently-to==bring .-.tl'1e brakeshoe into contact with the ground or pavementso that it will act as a drag brake.
The roller bracket can be adjusted along the stick to suit the height of the child so that the brake shoe will just clear the ground when the child is riding the toy in a positionwhich is natural and comfortable for him or her.
In Fig. 7 I show a modified-form in'xwhich a single roller 32 is mounted in any suitable .man-
ner in a bearing bracket 33 made fast in'or to the lower end of thestick 10. A brake ring--34 surrounds the stick above the roller and is provided with an attaching-pin or rivet 35and; a plurality of aligning holes--36. Any' suitable means may be usedfor adjustablymounting the brake ring in place on the stick .soto permit it,- asit is worn, to beaturnedaboutthe-stick and present new wear faces for serviceW-In the case of the brake shoe in Fig. 2 the -.shoecan be shown in Fig. 2 could be used in.-place:.of the caster roller .32 but suchwouldirequire the brake ring 34 toabe madeof larger diameter/thereby increasing-its weight and cosh-both. of which factors areundesirable. 1 I I I Also a ring brake like 34 could-be appliedbelowvtherollers 11, but Iprefer the .use of abrlake shoe that is lighter andelookszmoreilikea somewhatheavyferrule for the .stick- 10v which gives. a more trim and finished appearance to the'toy.
While I have shown my invention in buttwo forms, it will be obvious to those .sk'illedinthe art thatit is not solimited, but is susceptible .of
various other changes .and. modifications, withvout departing from the spirit thereof, and I desire,therefore, that only such limitationsushall be placed thereupon as are imposed .bythe .prior :mounted thereon, roller means mounted on the lowerend of the stick, a brake shoe surrounding -'the'-stafi near the roller means, and means to changeithehrelative position of brake shoe on the staff to present different wear surfaces on .the brake shoe for ground engagement.
