Application filed July 20, 1925;
kane, in Spokane County and State of- Washington, haveinvented certain new and 'useful Improvements in Amusement Trackways, of which the following is a specification. y
My present invention relates to an amuseinent trackway especially designed for use inA connection with a road or highway for :vehicles and also adapted for use in amusenient` parks. The trackway may be built as a lateral turn-out or detour from a road or highwayand extend for a suitable distance preferably parallel therewith, or the trackway maybe incorporated'in one of the main traiiic waysof an amusement park for passae'e therethrough of automobiles.
Means in the form of fixed or pern'ianent waves or. undulations are arranged in the trackway or specialroad way, to cause movement of the traifeling vehicle in a vertical plane and to produce surprising and pleasshocks or thrills, as a sourceof innocent fmeiriment for the occupants of the automobille, as well as for the spectators.
In carryingout my invention I preferably use a straight roadway having a tortuous alineme-nt comprising rises and falls,.and apparent obstructions are arranged in the `roadway with vehicle actuated means for removing the obstructions, las will be hereinafter more fully set forth and claimed.l
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention, and a slight. modification thereof, wherein the parts are combined and arranged according to one mode I have. thus far devised for the practica-l application of the principles of my invention.
Figure l is a diagrammatic or profile view of the roadway showing the undulations and obstructions, and indicatng an automobile traveling through the roadway.
Figure E2 is a plan view of the roadway showingits installation alongside a portion of a highway or road;
Figure 23 is a transverse.sectional view of the roadway showing the automobile wheels confined in depressed trackways or parallel grooves,
Figurev -l illustrates a modified form of the. trackway where parallel ci: bs or copings Serial No. 44,751.
are used as outer guards for the wheels of the automobile.
Figure 5 is a sectional view showing in detaillthe vehicle or car-actuated mechanism for removing an obstruction, as a pair of.Y
gates from the roadway.
Figure 6 is a plan view with parts in scc* tion ofthe car-actuated mechanism of Fig ure 5.
Figure 7 is a sectionalview parallel with the roadway illustrating an apparent rock or large stone in the roadway, with car-actuated mechanism for depressing/the obstruction.
In order that the general arrangement ofparts may readily be,v understood I have shown in Figure 2 a stretch or section of a highway as I-l with a turnout indicated as l to the special roadway 2, and a turn-in as 3, by means of which the car may depart from the highway andtravel through the special roadway and thence back to the highway again. y
The roadway is provided with grooved tracks 4l and 5 ofthe standard gauge for vehicles, and a curved entrance. and anexit for the car wheels `W of the automobile A, and these grooved tracks are of `suflicient depth to prevent the car either intentionally or accidentally from turning out of the grooved roadway after the latter has been entered, until the outlet is reached at the turnfin 3.
i In the modification shown in Figure l, the roadway 6 has a spaced-pair of parallel concrete copings or curbs 7 and 8 to conhne the wheels of the car to the roadway-to insure safety to the occupants of the ca r as well as to the car itself. 3In some instances these curbs may be utilized instead of the grooved tacks of Figure 3.
As best seen in the prolile view of Figure l successive undulations which comprise depressions` 8 andV hills 9 are constructed in the roadway. Preferably these undulations are` irregular both as to ldepth and height and as to length, andsome of the hills are of sufficient height as to prevent the driver and occupants of the car from seeing what is'before them in the roadway. For instance in the depression 8, what appears to he be a large stone or rockV l0 is located in1 edl the depression which is of sufficient depth as to be invisible to the driver until the car rises over the crest of the hill As a Insulti et rst .elenca a less Shok ai' thrill is given the driver and other occupants of the car, which is immediately dissipated through the operation of car-actuated means for removing the obst-ruction.
This rock or obstruction may be an inflated casing or bag that simulates a rock, or itmay be fashioned of rubber, or fashioned in other manner in order that the car may pass over it without danger to the safety of the car and its occupants. The car actuated mechanism is located over a pit P provided in the roadway into which pitthe obstruction may be depressed, or the rock may be a bag partially filled with air or gas so that it may be depressed or collapsed by a passing wheel without material damage to either the wheel or bag.
The car-actuated devices as shown in Figures 2 and 7 include two depressible rails 11. and 12 which are' located in the bottoms of the grooves 4 and 5 in the path of the car wheels lV and preferably these rails are longer than the distance between the wheels of the car. Thus as the front wheels of the car roll on the front end of the rails the latter are depressed and held in this position until the rear wheels of the car pass from the rails. The front wheels depress the rails to cause the rock to disappear, and the passage of the rear wheels from the rails permits them to return to normal position and restore the rock to normal position.
As seen in Figure 7 the car-actuated mechanism includes a depressible rail 11 pivoted at 12 on a beam 13 located in the pit l), yand a support- 14 in one of the pitwalls'provides a pivot 15 for the beam. There are two of these beams 13 and they are preferably joined by a cross brace or angle bar 16, with the rock 10 secured in suitable manner on the upturned end 17 in an opening 18 in the center of the roadway.
The free ends 19 of the rails 11 and 12 are resiliently supported on springs 20 located in pockets 21 of the wall of the pit, and the beams 13 are held in normal elevated position by means of springs 22 interposed between and secured at their ends to the complementary rails and beams. As the rails are depressed they encounter the cross brace 16 and they thus depress the beams to lower the rock. After the weight of the passing car is removed from the rails the rock returns to normal elevated position under action of the springs.
Other apparent obstructions, as for instance a pair of gates 23, 24, may be arranged across the roadway as seen in full and dotted lines in Figure 2. lThese are duplicate outwardly swinging gates with posts 25 having rotatable pintles 26 supported in bearings of base blocks 27 in the pits 28 at the sides of the roadway. The gates are swung' open by action due to `the passage of the ca r wheels over a pair of depressors or plates 29 preferably having rounded or arcuate top portions as indicated in Figure 5 and located in the grooves or tracks of the roadway. lllhen depressed the plates are latched or retained during the short intervals for the passage of the car, and then by action duc to the passage of the rear wheels over a pair of depressible plates 3() the gates are unlatched and permitted to automatically return to normal transverse position over the roadway.
Each depressor or plate 29 and 30 projects slightly above the bottom surface of the track, and the plate 29 is provided with an actuating lever 31 pivoted to a suitable support in the wall of the pit 28 at 32. At its free end the lever is fashioned with an arcuate rack 33 that meshes with the teeth of a rack wheel 34 on the horizontal shaft 35 journaled in bearings 36. The shaft 35 has keyed thereto a vertically arranged bevel pinion 37 that engages a horizontally disposed bevel gear 38 on the spindle 26 of the gate. post. By this train of mechanism it will be apparent that the gates are swung on their spindles from t-he transverse full` in Figure 2, and thence back to the norma full line position, as shown. The gates are thus opened to permit the free passage of a car, momentarily retained in ope-n position, and then automatically closed after the passage of the car.
After the passage of the car the gates are released by action due to the rolling of the rear wheels over the plates 30, and springs 39 on the gate spindles or pintles automatically return the gates and hold them in closed position.
The hinge pintles 26 of the gates are each provided with a radially extending, rigid latch hook 40 which turns with the pintle, and a latch or detent 41 forming part of a bell crank lever 42 is pivoted at 43 on a support in the wall .of the pit 28@ The bellcrank latch is pivotally connected by a rod 44 to a secondk bellcrank lever 45 which is pivotally supported at 46 in the wall of the pit, and the depressor plate 30 as seen in Figure 5 is pivoted to this second bell crank lever.
At one end the depressor 30 is pivoted to a support 47, and at its free end the depressor plate is rcsilicntly supported by a spring 46 on the fixed bracketI 49 beneath the trackway.
The roadway and tracks are built of suitable material, preferably cement concrete, and the walls of the pits may be of similar construction.
When the roadway is used alongside a highway, the former may be constructed in suitable length,.say 500 to 600 feet, and the car after once having entered the roadway is compelled to traverse its entire length before line. position to the open, dotted line positioi/ llO emerging from the distant end and coming` back to the highway. When used in an amusement park the roadway may be constructed as a portion of a main way through the park, throi h which roadway the car is compelled to entering` or leaving` the park.
