ARTHUR WARD, F SEATTLE, WASHINGTON.
SIDE BEARING- FOR MONORAIL GAE/S.
Specification of Letters Patent.
Patented Jan. 141, 1212.
Application filed May 23, 1918. Serial No. 236,091.
To all whom it may concern:
Be it known that T, ARTHUR WARD, a citizen of Canada, (who has taken out his first papers,) and resident of the city of Seattle, county ofKing, and State of Washington,
- have invented certain new and useful Tmprovements in Side Bearings for Monorail Cars, of which the following is a specification.
My invention relates to monorail cars and conslsts of an improvement wherein a pcculiar type of spring support is employed for engagement with the side bearing rails to resist the tendency of the car to rock sidewise.
The object of my invention is to provide a device for this purpose which shall employ springs as a yielding member and in such manner that the force of these springs shall be materially increased as the turning or rocking movement increases, this increase being secured by bringing into action additional springs.
In the accompanying drawings T have shown my invention in the form of construction which is now most preferred by me.
Figure 1 is a typical cross section of a car and track showing, largely, in a diagrammatical manner, the principles involved in my invention.
Fig. 2 is a horizontal section, also somewhat diagrammatic in its character, showing the parts which are involved in my invention.
Tn the drawing 1 represents a rail upon which the main bearing wheels 2 of the car run. This rail is shown as supported by a track structure 10, which is of the nature of a trestle, of any suitable type of construction. As herein shown, this support ing structure has longitudinal beams or bars 11, upon which are mounted the side bearing rails 12.
These features of construction are common in the art and may be of any character which is or may be found suitable for this purpose. The particular detail of their construction is immaterial to my invention.
The type of car herein illustrated is one which has two body parts 30, placed at opposite sides of the track and carried mainly by suspension from the supporting frame work and axle of the car. In other words, these parts extend down and overlap the side of the trestle work upon which the traelrway 1 is carried Upon; the inner face of each of these sections 30 of the car, is mounted a spring or springs a, which curve inward or away from this portion of the car body and toward the side bearing rails 12.
Associated with this is a spring 5, herein shown as a semi-elliptical spring, which is mounted at the center of its length so as to pivot upon the car. This pivoting is illustrated as secured by employing clips 50 which embrace the spring and which are supported by a pin or pins, 51, carried by eye-bolts 52 which are secured to a por tion of the car structure.
Journaled upon the ends of the spring 5 are two side bearing wheels 6. One of these is provided with projecting journals which enter a slot 70 in a head or yoke 7.
carried by the outer or free end of the spring 1. Under normal conditions the spring 4 will hold the side bearing wheels 6, to which it is directly connected, inward or away from the car body 80 and in contact with the side bearing rail 12. When any cause produces a rocking movement of the car it will tend to compress this spring at one side of the car and to force its free end near to the car body. The spring 4 is the only force resisting this tendency until a certain amount of movement has occurred.
As the wheel 6, which is in contact with the side bearing rail, is moved horizontally it swings the spring 5, which is directly secured to its pivot, until the companion wheel which is secured to the other end thereof, is brought into contact with the side bearing rail 12. Any movement coming after this must overcome the resistance of the spring 1 and that of both ends of the spring 5.
In consequence of this construction, the first or slight rocking movement of the car is permitted to occur with comparatively small resistance, but when this reaches a certain amount increased resistance brought into edect greater than that which would occur by reason of the greater bending of the spring 4. The excessive rocking of the car is thus prevented while the ordi nary normal movements are easy and soft, as occurs where a supporting spring is nicely proportioned to the weight carried thereby.
at T claim as my invention is:
1. A. side bearing device for mono-rail.
Wheels journaled on the two ends thereof, 10
a leaf spring secured by one end to the ear and extending lengthwise the our said spring having a yoke on its free end having slots engaging the journal of the Wheel.
Signed at Seattle, Washington, this 10th 15 day of May 1918.
ARTHUR WARD.
