SPEED-'WARNING- DEVICE.

Application led June 25, 1927. Serial No. 201,407.

This invention relates to. an improved speed warning device which may be attached to the radiator cap, motor meter or to any other desired part of an automobile or other vehicle, and which will be operated by the pressure or movement of air to warn the driver when the car is being driven at a dangerous speed.

A further object is to provide a device of this character which includes a danger signal normally hid from view but caused to be elevated and be exposed when the speed of the car becomes excessive.

`With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a View partly in elevation and partly in vertical longitudinal section illustrating my improved device attached to the motor meter of an automobile;

Figure 2 is a view in longitudinal seetion on the line 2-2 of Figure 1;

Figure 3 is an enlarged view in transverse section on the line 3-3 of Figure 1;

Figure 4 is a fragmentary view in elevation illustrating a modification.

1 represents a post or upright which is preferably of metal and which may be attached to a motor meter 2, as shown in Figure 1, or it may be provided with a screwthreaded stud 3 having nuts 4 thereon for attachment directly to a radiator cap. In fact, it is to be understood that my improved device may have any suitable means whereby it may be attached to any part of the vehicle desired.

The post or upright 1 is somewhat V- shaped at its upper end, preferably having spherical enlargements 5 at its extremities. The post also has a recess 6 in its upper end communicating with a longitudinal bore 7 In the longitudinal bore 7 a vertical pin 8 is located and fixed at its lower end in the post. This pin S has a bifurcated upper end, and in the bifurcated portion a pair of

' rollers

9, 9 is mounted in vertical alinement. These rollers project beyond the edges of the pin and engage the walls of the tubular lower end 10 of a vertically movable member 11.

The member 11 at its lower extremity is made with inwardly projecting spring fingers 12 which not only serve to limit the downward movement of the member 11 but also limit the outward or upward movement of said member as they will engage the rollers. These spring fingers can be forced past the rollers for a complete removal of the member 11 or a reassemblage of the parts as occasion may require.

The post l at the lower end of its bore 7 1s provided with drain outlets 13 through llwhich water may pass if it collects in the ore.

I would call particular attention to the fact that the bore 7 and thetubular lower end of the member 11 are of somewhat oblong shape so as to prevent any turning movement of the member 1l within the post. As a matter of fact, the member 1l will be prevented from anyvsuch turning movement by reason of the fact that it has a figure 12 integral therewith or fixed thereto which is normally housed within the recess 6. This ligure preferably represents a skull although it may be of any desired design. The

rollers

9, 9 extend beyond the post and into grooves in the lower portion 10 of member 1l, which prevents any turning movement of the part.

A pair of

diverging wings

14, 14 is fixed to or made integral with the upper end of the member 11 and conforms in general contour to the upper end of the post. However, as clearly indicated in Figures 1 and 2, these wing portions 14 are so shaped as to provide an entrance space or groove 15 between the upper end of the post and the wings so as to admit air, and when the pressure of the air becomes excessive it will cause these wings to elevate, elevating the member 11 and figure 12, which constitute a single operating unit.

It will also be noted that the extremities *of the wings 14 are somewhat cup-shaped, as

shown at 16, to rest over the spherical enlargements 5 when the gure or movable member is in its lowered position.

The broad idea of this device is to provide a danger signal or a warning of danger. Hence the figure 12typiiies a skull which is normally hidden from view but which when the speed of the car becomes excessive will move upwardly and be exposed, and will fall back into its enclosure as the speed decreases.

The invention is of course capable of a wide range of modification and design and in details of construction, and while I have illustrated what I believe to be a preferred embodiment of my invention it is obvious lull that various changes and alterations may be made on the general form of the parts described without departin from my invention and hence I do not llmit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A device of the character described, including a hollow post, a vertically movable member mounted in the post and normally hid from view, and means on the upper end of the member so shaped that an air entrance is provided between the same and the post so that said member is elevated by the action of air against the edge of said member when the speed of the vehicle to which the post is secured becomes excessive.

2. A device of the character described, including a hollow ost, a vertically movable member mounted in the post and normally hid from view, and means on the upper end of the member causing said member to be elevated by the action of air against the said means when the speed of the vehicle to which the ost is secured becomes excessive, said mem r having a danger signal in the form of a figure constituting a part thereof and normally enclosed in the post.

3. A device of the character described, including a post having a V-shaped up er end and having a recess 1n its upper en and a longitudinal bore communicating with the recess, a vertically movable member enclosed in the recess of the longitudinal bore, and

wings fixed to the member and resting upon the V-shaped upper end of the post, said wings disposed at an angle and so positioned relative to the post as to provide an air inlet under said wings.

4. A device of the character described, including a post having a longitudinal bore, a pin fixed in said bore, rollers carried by said pin and projecting from the surface of the pin, a vertically movable member having a tubular lower end receiving the pin and engaged by the rollers, a figure constituting a part of the vertically movable member and normally enclosed in the post, and wings on the upper end of the movable member above the post adapted to be engaged by the wind to cause the member to elevate and move the figure into position where it ma he seen.

5. A device of the character (lbscribed, including a post having a longitudinal bore, a pin fixed in said bore, rollers carried by said pin and projecting from the surface of the pin, a vertically movable member having a tubular lower end receiving the pin and engaged by the rollers, a figure constitutin a part of the vertically movable member an normally enclosed in the post, wings on the upper end of the vertically movable member above the post adapted to be engaged by the wind to cause the member to elevate and eX- pose the ligure, and spring lin ers on the lower end of the movable mem r limiting the downward and upward movements of said member.
