Description
'1Gv provide novel means on the skate for preventing Patented Sept. 18, 1934 UNITED STATES Pivrwr ori-"liceA ROLLER SKATE George A. L. Draws, Milwaukee, Application March 22,' 1934, Serial No. 716,787
5 Claims.
This invention appertains to roller skates either of the rink yor sidewalk type. f
One of the primary objects of my invention is to provide a roller skate having a novel form of 5` brake mechanism on the wheels thereof, whereby persons can quickly and conveniently stop without danger of marring the surface on which they are skating. v
Another salient object of my invention is to retrograde movement of the rollers, so that persons will be eifectively prevented from` rolling backwards down an inclined surface.
A further important object of my invention is to provide a novel unit for a roller skate, embodying a brake drum connectedA and rotatable with the wheels of the skate, and a brake shoe pivotally carried by the skate body for braking v engagement with the drum when pressure is applied by thefoot toa ground roller carried by the brake shoe, the drum and skate body being provided with a novel ratchet mechanism to prevent the 4reverse or backward movement of the wheels.
A further object of my invention is to provide a novel means for incorporating the unit in a skate, whereby repairs and replacements can be conveniently and quickly made.
A still further object of my invention is to provide an improved skate of the above character, which will be durable and eiiicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market -at a reasonable cost.
With these and other objects in view the invention consists in the novel construction, ar-
rangment and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in
which drawing:
being shown broken away ,lustrate structural details.
and in section toil- Figure 2 is a transverse, sectional View through ferred or conventional structure.
The forward end of the foot plate 5 carries the front wheels .6, and this front wheel structure can be of any desired type or character.
The usual toe clamps 7 are carried by the front of the skate. The rear part of the foot plate is also provided with the usual heel seat for carrying the angle strap 8. The heel part-of the foot plate 5 can carry depending brackets 9 for supporting the rear axle 10 on whichV is rotatably mounted the rear wheels 11 and 12.
In the present instance the wheels 11 and 12 include companion'hub plates 13 and 14 for receiving therebetween a tire 15 which can be formed of rubber. Disposed between the hub plates 13 and 14 are ball bearing races 16 for the ball bearings 17, which ride on cones 18 disposed upon theA axle. Inner hub plates 14 on each wheel carry inwardly directed, axially disposed threaded hub sleeves 19, and a brake drum or hub spool 20 of annular form is arranged 'between' the inner hub plates. The bore ofthe hub spool or brake drum is internally threaded for receiving the threaded hub sleeves 19. The outer face' of the spool or drum 20 have attached thereto any preferred type of renewable brake line 21, which can be formed of asbestos, if desired. Y
During the assembling of the rear rollers 11 and 12 with the brake drum, ratchet wheels 22 and l 23y are clamped between the inner hub plates 14 andthe drum, and if desired the ratchet' wheels can vbe rigidly secured to the drum by means of fastening screws. The ratchet wheels 22 and 23 extend beyond the periphery of the spool or drum and form a housing for the brake lining 21.
Rockably mounted on the skate body or foot- 1. plate 5 is an arcuate brake shoe 25, which extends between the ratchet wheels 22 and 23, and this brake shoe follows the curvature of the drum. Formed on the rear end of the shoe 25 is an arm 26, which carries an axle 27 on which is rotatably mounted a small, round roller` 28. 9 The upper end of the arcuate brake shoe 25 has formed thereon a forwardly and angularly extending leg or stop lug 29, for a purpose which will be later set forth.
A contractile coil spring is connected to theA extreme outer end of the lug 29 and to the footplate, and normally tends to move the brake Y shoe 25 away from the brake drum and the roller 28 into engagement with the ground'. The downward Swinging movement of the brake shoe 05 and roller 28 can be limited by means of a screw 31, which is adjustably carried by the foot-plate. Obviously by adjusting the screw 31, the position of the roller 28 with relation to the ground can be accurately determined.
Ico
Pivotally carried by the rear end of the foot plate is a depending ratchet dog 32 having a relatively broad, inwardly directed, transversely extending tooth 33 for engaging the periphery of-the ratchet wheels 22 and 23. The dog is normally urged towards the teeth of the ratchet Wheels by gravity, and by referring to Figure 1 of the drawing, it can be seen that when the skate `is moving in a forward direction, the wheels will be turning in a counter-clockwise direction, and the teeth of the ratchet wheels will catch on the dog 32, thereby preventing further movement of the wheels.
I prefer to mount the shoe 25 and dog 32 inl a special manner on the skate, and hence I provide a removable heel-plate 34 for the footplate 5 of the skate, and the foot-plate at its rear end is provided with an opening for receiving the heel-plate. The heel plate can be removably held in position by the use of suitable screws. The lower face of the heel-plate 34 carries depending brackets 35 and 36.
During forward movement of the skate, a person can conveniently and quickly stop his movement by pressing downwardly and backwardly on the roller 28, and obviously the brake shoe 25 will be forced into engagement with the brake drum. Obviously, by governing the force of pressure on the roller 28, the quickness of the braking action can be regulated.
In assembling the skate, the rear wheels and the brake drum are assembled as a single unit, and are placed between the brackets 9, after which the axle 10 is slipped through the brackets, bearing cones, and drum. A spaced sleeve 2e can be placed on the axle 17 between the cones 18, if desired.
From the foregoing description it can be seen that I have provided a roller skate, in which a novel braking unit, and means for preventing backward movement of the rollers, are provided.'
Changes in details may be made without departing from the spirit or scope of this invention, but what I claim as new is:--
. 1. In a roller skate, a foot-plate, an axle, a pair of rollers rotatably mounted on the axle, a brake drum disposed between and rigidly connected to the rollers, and a pivot brake shoe movably mounted toward and away from the drum, and a ground roller carried by the shoe.
2. In a roller skate, a foot-plate, an axle, a pair of rollers rotatably mounted on the axle, a brake drum disposed between and rigidly connected to the rollers, a pivot brake shoe movably mounted toward and away from the drum, a ground roller carried by the shoe, and resilient means normally urging the shoe away from the drum and roller toward the ground.
3.

4. In a roller skate, a foot-plate, an axle carried by the foot-plate, a pair oi wheels rotatably mounted on the axle, a hub spool disposed between the wheels, ratchet wheels secured between the hub spool and the wheels, the wheels, hub spool and ratchet wheels rotating as a unit, a pivoted pawl carried by the foot-plate for engaging the teeth of the ratchet wheels, a brake lining on the spool, and a pivoted brake shoe partially encircling the spool having a groundengaging roller.
5. In a roller skate, a foot-plate, depending bracketson the root-plate, an axle removably associated with the brackets, ground wheels rotatably mounted on the axle having inwardly directed, axially disposed threaded hub sleeves, a brake drum having an internally threaded bore 115 receiving said sleeves, ratchet wheels clamped between the brake drum and ground wheels, a brake shoe pivotally secured to the heel plate having a ground-engaging roller on its lower end and partially encircling the drum, and a 120 pivoted pawl carried by the foot-plate for engaging the teeth of the ratchet wheels.
