TRACK AND CAR.
SPECIFICATION forming part of Letters Patent No. 745,855, dated December 1 1903.
Application filed August 3, 1903. Serial No. 168,018. (No model.\
To aZZ whom it may concern.-
Be it known that I, STEPHEN E. J ACKMAN, a citizen of the United States, and a resident of the city of New York, (Goney Island, borough of Brooklyn,) in the county of Kings and State of New York, have invented a new and Improved Track and Car, of which the following is a full, clear, and exact description.
The invention relates to railways, such as switchback or inclined railways, used in pleasure resorts, exhibitions, and the like.
The object of the invention is to provide a new and improved track and car arranged to insure an easy running of the car, permitting the use of non-flanged car-wheels, to reduce the friction to a minimum, especially when the car travels around curves in the track, and to prevent the car from leaving the trackrails.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a plan view of the improvement. Fig. 2 is an enlarged plan view of the same, showing the car on a curved portion of the track. Fig. 3 is a similar view of the same, showing the car on a straight portion of the track. Fig. 4 is a side elevation of the improvement, and Fig. 5 is a transverse section of the same on the line 5 5 of Fig. 4.
The car A is adapted to travel on a track 13, consisting, essentially, of track-rails B and B and side guard-rails B and B, following the shape of the track-rails and located a distance above the track-rails and somewhat to the sides thereof, as plainly indicated in Fig. 5.
On the sides of the car A are secured brack ets 0, each carrying in its top portion a vertically-disposed pivot D, on the lower end of which is journaled a bearing E, preferably in the shape of a fork, supporting in its sides an axle F, engaging the hub G of a nonflanged car-wheel G, mounted to travel on the top of the track-rail B or B as plainly indicated in the drawings.
The bearings E of the front car are pivotally connected with each other by a crossbar E, and a similar cross-bar E connects the bearings of the rear car-wheels with each other, as shown in Fig. 1.
By the arrangement described the several car-wheels G of the car A are free to revolve on their shafts F, which are secured by set screws F in the bearings E, and the latter are free to turn on the vertical pivots D; but the bearings of the front wheels turn in unison with each other, owing to the pivotal connection by the crossbar E, and the bearings for the rear wheels turn in unison, owingto their connecting-bar. E.
Each of the bearings E is provided with arms E and E extending in opposite directions, and in the free end of the arm E is journaled a horizontally-disposed frictionroller E adapted to travel on the inner face of the corresponding guard-rail B or B (see Fig. 1,) and the free end of each arm E is connected with one end of a spring H, attached at its other end to the corresponding bracket C. Now by the arrangement described the spring H of each bearing has the tendency to hold the friction-wheel E in contact with the corresponding guard-rail B or B to hold the bearings E in such positions that their car-wheels G always travel in the middle portion of the track-rails B and B and consequently a derailment of the car is rendered impossible, and at the same time the car can readily pass around curves without creating undue friction, as the friction-rollers E travel in contact with the guard-rails B and B and are mounted on the yielding bearings E to allow the friction rollers to readily follow the curvatures of the guard-rails B and B,
It is understood that the cross-bars E cause the front bearings and the rear bearings to work in unison; but this is not absolutely necessary, as the bars may be omitted to allow each bearing to turn on its pivot D, ac cording to the curvature in the correspond ing guard-rail B or B In the top of each bracket 0, near the outer end thereof, is arranged a horizontally-disposed friction-wheel I, mounted to rotate loosely on a suitable spindle I, fastened in the bracket 0, and each friction-wheel I is adapted to travel on the corresponding side guard-rail B or 3*, so as to take up all sidewise motion of the car, especially when the latter is traveling around curves, it being understood that the spindle Iis arranged in transverse alinement with the pivot D, and hence the said spindle and pivot always bear the same relation to each other, while the axis of the friction-roller E varies in its position relative to the said spindle and the said pivot 1), according to the curvature in the track and the action of the spring H.
In the top of each bracket C is formed an oilwell 0, containing oil or other suitable liquid lubricant, and the bottom of this oil-well O is connected by a block J of porous m aterial such as ratan, porous oak, or the likewith an opening K in a bearing-plate K, resting on a bearing-plate K having an annular groove K in register with the opening K, the said bearing-plates K and K being interposed between the top of the bearing E and the under side of the top portion of the bracket 0, as plainly illustrated in Figs. at and 5, to allow of convenient turning of the bearing E on the pivot D. Now the lubricant percolating through the oil-block J and the opening K passes into the annular groove K and between the bearing-plates K and Y so as to thoroughly and continually lubricate the same. An annular oil-well G is formed in the web of each car-wheel G around the hub Gr, and a block G similar to the block J, is held in the hub G to connect the oil-well G with the axle F to lubricate the same. A channel F is formed in the axle F and leads from one out-er end of the same to the oiled portion thereof to allow lubricating the axle by the operator whenever it is deemed necessary to do so.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a car-track having track-rails and side guard-rails, of a car having non-flanged car-wheels traveling on the top of the said track rails, a springpressed bearing for each wheel to turn in and capable of turning on a vertical axis, and a friction-wheel disposed horizontally and j ournaled on each bearing and pressed in contact with and traveling on the corresponding side guard-rail, as set forth.
