Specification of Letters Patent. Patented March 10, 1908. Application filed July 16, 1906. Serial No. 326,319.

' l5. 'lhe gear 12 is provided with an inward extension 12" forming a wearing plate which engages track wheels 16 which give an antifrictional support to the gear wheel 9. The

with a pulle; 17 which may be connected with any suitable power for operating the ratchet wheel. (enrrally secured to the base 5, is a hollow upright shaft 18 which is sur rounded by a loose sleeve 19 whose lower extremity is outwardly flared as shown at 20 to engage a circular brake block 21 made fastto the upper surface of the wheel 9. The sleeve 19 is provided with'a loosely fitting tren'iity ofa rod 6] to which is applied a. nut

-22 whereby the rod is connected with a cap.

Between the cap and the hollow shaft 18 is located a coil spring 23 the tendency of which is to support the cap whereby the brake sleeve is relieved from pressure from above when" the-brake is not applied. The rod 61 passes downwardly. from the cap through the hollow shaft and ;is connected below the gear 9 asshown at 24 withorie arm of a bell crank 1e ver 25., This lever is fulerumed at 26 and its other arm is connected at 27'wit-h an operating, rod whose extremity remote from thebellcrankfls connected shown at 2.) with an o[')erating lever 30 fulcrumed at 31 and provided with a locking device 32 coop'erating with a quadrant 33.

At a suitable distance from the wheel 9 is located a circular platform 34 surrounding the wheel 9 and forming an umlulating track for vehicles .35 which are connected by means of sweeps 36 with the brake sleeve It). The innenextremity of each sweep is provided with an eye or circular bearing 37 which surrounds and loosely engages the brake sleeve passes the upper it its outer extremity 9. -As shown in the drawing there are three I sweeps and conse'q uent ly three sweep eyes 37, The lower of these eyes is loea'ted directly above a shoulder 38 formedon the lower extremity of the brake sleeve. The eyes of the respective sweeps are separated: by washers There is a similar washer located above said eye from a platform 40 which also loosely This platform is provided with depending parts 41 which lie within the: path ofthe sweepsand prevent the vehicles from colliding with (Zach other. i

Each sweep is connected with the wheel!) bymea'ns of a spring-actuated pawl 42. This it by virtue of the engagement of the straight as to prevent this result, since before one colliding.

pawl is mounted in a casing 43 secured to the lower surface of the sweep. Within this casing is located a spring- L4 which acts on the pawl and normally thrusts the beveled extremity of the latter outwardly to engagement with the teeth 10 of the ratchet wheel.

When the apparatus is in operation, the ratchet wheel is rotated in the direction indieated by the arrow in Fig. 4, whereby the ratchet wheel carries the sweeps along with oilsets of the ratchet teeth with the pawls of the sweeps. However, by virtue of the undulatory construction of the vehicle track, it happens that the vehicle when moving downwardly on one of the inclined partsof the track, may acquire a speed greater than the speed of the ratchet wheel. In this eventthe sweep together with the vehicle runs ahead of the ratchet wheel so to speak and the pawl 42 slips over the teeth of the ratchet. When this occurs it may happen that one of the vehicles would have a tendency to come in contact with another, but the depending parts ll of the platform 40 are so arranged vehicle could collide with another, its sweep would strike a projection 41 and interfere with its movement sufficiently to prevent a collision. In other words the depending projections 41 of the platformAO are so arranged as to prevent any two vehicles from The sweeps 36 are composed of two members 36 and 36 pivotally connected at 45. The member 36 has a pin 46 passing through a slot 47 formed in the member 36 whereby the movement is limited. This jointed sweep oonstruction'is important in view of the undulating condition of the track necessitating a certain degree of movement of one sweep member upon the other. Furthermore the outer extremity of each sweep is provided with a sleeve 48 adjustable longitudinally thereon by means of nuts threaded on the sweep and engaging the extremities of the sleeve: This sleeve body 48 is provided with a sleeve 49 extending at right angles to the member 48, and surrounding the-reach 50 of the vehicle. The sleeve member 49 is free to turn on the reach, thus giving the sweep su'l'licicnt movement with reference to the vehicle, for all practical purposes.

From the foregoing description the use and operation of my improved apparatus will be readily understood. Power being applied to l the shaft 14, the wheel 9 is rotated through the instrumentality of the gears 13 and 12, the said wheel turning around the central l hollow shaft 18 which maintains the gear in l operative relation with the other parts. The i rotation of the wheel 9, imparts a swinging l movement to the sweeps and engagement of the ratchet teeth with the pawls of the sweep: f In this way the vehicles a e caused to travel i sensors around the undulatory circular track. This track is highest at its outer edge and slopes downwardly at a suitable inclination (sw- Fig. 4), whereby the centrifugal force inci dent to the travel of the vchiclcs is practically neutralized or ovcrcomc.

In further explanation of the uclion ol the brake mechanism, attention is cullcd to ihc fact that this mechanism acts only lo check the speed of the o cratii'ig whccl l). in other words when it is dl sircd to stop the mnchinc, by ap lying the brake whcrcby thc cup (H1 is force downwardly upon the slccvc H), the outwardly flared extrcmity 20 of the slccvc .is forced tightly against the shoe 2] of the wheel 9 thus having a tendency to stop the wheel.

It will be understood that the cup is locked against rotation by virtue of its connection with the bell crank lever 25 by the rod (31..

This brake mechanism docs not directly af-,

feet the speed of the vehicles except so far as the stopping of the operating wheel has this tendency. After the opera ting wheel 9 ceases to rotate, the vehicles are at liberty to continue their movement by virtue of their acquired speed or momentum and will continue to move until the friction of the parls sto s them.

. aving thus described my invention, whut I claim is:

1. In amusement apparatus, lhc coinbinu tion of an operating whccl provided with ratchet teeth, a central shaft, vchiclc swccps connected with the central shall indcpcndently of each other, each swccp having a ratchet and pawl connection with said whccl whereby the sweeps are propcllcd. by thc iotation of the wheel, all of thc swoops being connected. with the wheel and free lo truvcl 'laster than the Wheel and indcpcndcmlv of nation of an operating wheel, vehicle sweeps A mounted to swing indcpcmlcnlly of ihe wheel and independently of each other, a pawl and ratchet connection botwccn lhc sweeps and the wheel, means for opcrnting the wheel, and a platform mounted :ibovc the wheel and .rovidcd with dcpcnding projections locatcdhn the path of the swoops for the purpose set forth.
