Description
Aug. 12, 1947. J, F, STEWACK 2,425,574 BRAKE FoR BABY GARRIAGES Eil-ed Aug. 24, 1945 Patented Aug. 12, 1947 UNITED vls'rA'r'lazs PATENT OFFICE BRAKE FOR BABY CARRIAGES John F. Stewack, Downers Grove, Ill.
Application August 24, 1945, Serial No. 612,441
(Cl. 18S-20) 3 Claims. l
The present invention relates to brakes for baby carriages and the like.
The primary object of the invention is to provide a safety catch, normally in operative position, to prevent a baby carriage and the like from rolling unless released by an attendant.
Another object of the invention is to provide a safety catch of simpler and more compact construction than what is disclosed in prior devices.
With the foregoing and other objects and advantages in view, the invention consists of the novel arrangement and construction of parts hereinafter described and claimed.
In the accompanying drawings illustrating the invention,
Figure 1 is a longitudinal section of rear end of a baby carriage with invention installed.
Figure 2 is a top plan view thereof.
Like numerals are employed in the description and drawings to designate the same parts of construction.
The rear wheels I are rotatably mounted on axle 2 which is supported on the longitudinal under frame 3 of the carriage. This frame is provided with the upwardly and rearwardly eX- tending arms 4 of the connecting handle bar 5 which is mounted rotatably therebetween. Mounted concentrically on the hubs of said wheels on their inner sides are the fixed discs 6 which are adapted to revolve with the wheels. f
These discs are provided around the perimeter with a plurality of transverse recesses or grooves 'l adapted to normally seat the transverse rollers 8 which are mounted in the bifurcated end of superimposed, forwardly projecting arms 9. Arms 9 are rotatably mounted on the ends of a transverse rocker shaft I which is rotatably supported on the frame 3. Between the hubs on said arms il and the supports for shaft I are fixed collars II provided with lateral fingers l2 which engage the undersides of said arms. Coiled springs I3 are secured to the undersides of the arms 9 and top of frame 3 and are adapted to normally depress the said arms and hold the rollers 8 in engagement with grooves l of discs 6. Centrally of the shaft I0 a rocker arm I4 is secured thereto and to the top of said rocker arm is pivotally attached a release rod I which eX- tends to the handle bar 5 to which it is pivotally connected by a short arm I6 projecting from the said handle bar. This short arm is adapted to move either up or down and thereby draw the release bar l5 rearwardly. This movement draws back the rocker arm I4 and elevates the 2 two arms 9 through the lifting action of the iingers I2, thus disengaging rollers 8 from the grooves on the discs 6. This allows the wheels I to roll freely.
It will be understood that the coiled springs I3 may be dispensed with if the two arms 9 are constructed with sufficient weight to cause them normally to drop into the position shown in Figure 1. This change would be within the scope and spirit of the invention.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A wheel vehicle consisting of traction wheels and a rotatable propelling handle;v peripherally grooved discs mounted concentrically on said wheels and adapted to revolve therewith, a transverse rocker shaft mounted on the under frame of said vehicle and provided with a rocker arm pivotally connected to said rotatable vehicle handle; longitudinally disposed bifurcated arms revolvably mounted on said rocker shaft and provided with transversely disposed rollers mounted in the bifurcations of said arms and adapted normally to seat in grooves in said discs and prevent rotation thereof; lifting ngers secured to said rocker shaft and engaging the undersides of said bifurcated arms and coiled springs interposed between said arms and the under-frame of the vehicle and adapted normally to effect engagement of the said rollers and grooves.
2. A wheel vehicle comprising traction wheels, a rotatable propelling handle thereon, peripherally grooved discs mounted concentrically on f' said wheels and adapted to revolve therewith, a
transversely disposed rocker shaft provided with a rocker arm pivotally connected to said handle, longitudinally disposed bifurcated arms revolvably mounted on said rocker shaft, and a transversely disposed roller mounted in each of said bifurcated arms and adapted to normally seat in a groove of one of said discs complemental thereto and prevent rotation thereof.
3. A wheel vehicle comprising traction wheels, a rotatable propelling handle thereon, peripherally grooved discs mounted concentrically on said wheels and adapted to revolve therewith, a transversely disposed rocker shaft provided with a rocker arm pivotally connected to said handle, longitudinally disposed bifurcated arms revolvably mounted on said rocker shaft, a transversely disposed roller mounted in each of said bifurcated arms adapted to normally seat in a groove of one of said discs complemental thereto and 2,425,574 3 v prevent rotation thereof, and lifting fingers secured to said rocker shaft and engaging the underside of said bifurcated arms.
