FOLDING STEP FOR VEHICLES.
T all whom it may concern:
Be it known that I, CHARLES BLACK, a citizen of the United States, residing at Hawesville, in the county of Hancock and tate of Kentucky, have invented certain new and useful Improvements in Folding Steps for Vehicles, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to improvements in folding steps for passenger cars, coaches, buses and similar vehicles.
The object of the invention is to provide a simple and practical device of this character having a lower step or step section which may be quickly and conveniently lowered and raised by the conductor, motorman, driver, or other person upon the platform of the vehicle.
With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully de scribed and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a detail end elevation of a portion of a passenger car or coach showing the application of the invention thereto; Fig. 2 is a detail vertical section through a portion of the platform and showing the opposite side of the steps; Fig. 3 is a side elevation of a portion of one end of the car showing the steps in front elevation; Fig. 4 is a top plan view of the steps removed from the car; and Fig. 5 is a detail section showing the hinge for the lower folding step or step section.
In the drawings 1 denotes a portion of the body of a car, coach or other vehicle, and 2 denotes the platform of the same;
The improved steps consist of a station- I ary section 3 and a foldable step or step section 4. The step section 3 consists of two side members 5 united by the treads 6 and risers 7. The step section 4 may consist of any number of treads or steps but, as illustrated in the drawing, it consists merely of a single step adapted to fold upwardly and inwardly and upon the lowermost tread 6. It is of right angular form and has a broad portion 8 forming a tread and a narrow portion 9 forming the lower part of the lowermost riser 7, to which latter it is connected by hinges 10.
11 denotes a lever for actuating the folding step section 4. Said lever has a sliding Specification of Letters Patent.
Application filed July 23, 1908.
Patented Nov. 10, 1908.
Serial No. 445,037.
pivoted at 14 to one end of the step 4 and its upper end is connected by a link 15 to the lower end of an operating lever 16. The latter extends through a slot or opening in the platform 2 and is pivoted therein, as shown at 17. The upper end of the lever 16 is provided with an handle 18 and carries a slidably mounted spring projected and hand retracted pawl 19 adapted to engage a segmental locking rack 20 suitably mounted upon the car. It will be seen that when the pawl 19 is retracted from its locking rack and the lever 16 is oscillated the step or step section 4 will be raised or lowered according to the direction of movement of said lever. When the step 4 is lowered, as shown in Fig. 1, and the handle end of the lever 16 is swung to the left the link 15 will draw downwardly upon the upper end of the lever 11 so that the latter will swing upon its pivot 13 and at the same time slide outwardly or longitudinally to a slight extent to allow the pivot 14 to swing around the hinge 10 and the continued movement of said link will then draw or slide the lever 11 longitudinally in the opposite direction or inwardly so that the step 4 will be swung up and over upon the lower tread 6 of the stationary steps 3.
In order to effectively brace the step 4 when lowered, stop pins 21, 22 are provided upon the step or step section 3 for engagement by the lever 11, as shown in Fig. 1; and in order to cause both ends of the step 4 to be similarly supported and operated a link or lever 25 similar to the lower end of the lever 11 is provided upon the opposite side of the steps 8. Said link 25 is pivoted at one end at 26 to the step 4 and has at its other end a slot 27 to receive a pin 28. A stop pin 29 similar to the pin 21 is provided for the engagement of the link 25 when the 'step 4 is lowered. In the side members or plates 5 of the steps 3 may be formed notches for the reception of th pivots 14, 26 when the step 4 swings to its closed position.
Having thus described the invention what is claimed is:
1. In a device of the character described, the combination of a stationary step section, a movable step section hinged to swing up- "\vardly and" over upon the former and an actuating lever connected to the movable step section and slidably and pivotally mounted.
2. In a device of the character described, the combination of a stationary step section, a movable step section hinged to swing upwardly and over upon the former, an "actuating lever formed with a longitudinal slot and pivoted at one end to the movable step section, a fulcrum pin upon the stationary step section and arranged in said slot in the lever and means for actuating said lever.
B. In a device of the character described, the combination of a stationary step section, a movable step section hinged to swing upwardly and over upon the former, a lever pivoted at its lower end to the movable step section and formed intermediate its ends with a longitudinal slot, a fulcrum pin upon the stationary step section and arranged in said slot, an operating lever, and a link connecting the latter to the first mentioned lever.
l. In a device 01": the character described,
the combination of a stationary step section,
a movable step section hinged to swing upwardly and over upon the former, a lever pivoted at its lower end to the movable step section and formed intermediate its ends with a longitudinal slot, a fulcruinpin upon the stationary step section and arranged in said slot, an operating lever, a link connecting the latter to the first mentioned lever, means for locking said operating lever in' an adjusted position, and a stop pin upon the stationary step section for engagement by the first mentioned lever.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses. CHARLES BLACK.
