CHAIN GEARING .AND SPACING MECHANISM.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed March 3, 1908. Serial No. 419,054.

To all whom t may concern:

Be it known that I, FREDERICK DARGY, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented a new and useful Chain Gearing and Spacing Mechanism.

My invention relates to that class of gearing and spacing mechanism, by means of which vehicles may be propelled along a curvilinear and straight path of travel crossing itself at intervals. One object of my invention is to provide a direct means of propelling vehicles and vehicle carriers over a straight and curvilinear path of travel crossing itself at intervals by means of chains engaging with each other and having recesses which receive vehicle carrying rods.

Another object is to provide means by which a constant distance may be maintained between a plurality of vehicles having a common straight and curvilinear path of travel crossing itself at intervals.

I attain these objects byvmechanism illustrated in the accompanying drawings; in which Figure l is a top view of my invention as applied to a merry-go-round, showing machine with parts of platform and mechanism cut away. Fig. 2 is a longitudinal vertical section of Fig. l, about the line A-A, with parts cut away. Figs. 3, 4L and 5 are enlarged detail views of my invention. Fig. 6. is a modification of my inventionas it may be used in connection with a recessed toothed wheel. Fig. 7. is a top plan view showing parts of platform and path of travel of vehicles when4 my invention is used in connection with a recessed toothed wheel. Fig. 8. is a detail view of part of the vehicle carrying rods, guide way, etc. Fig. 9. is a top view of crossing guide ways, vehicle-carrying rod, guide bar and tracks at and near their crossing point.

Referring to the drawings in which the same reference characters refer to the same or corresponding parts in all of the views, a and c are socket castings which are bolted to a solid foundation. FiXedly mounted in a and a are shafts or axles b and b. Rotatably mounted on the shafts Z9 and o and having bearings on the castings a and a are wheels o and CZ. c and Z have fiat rims and to these rims are screwed flanges c and o2, d and CZ2. Clamped to the shaft ZJ is a framework e, upon which is xedly mounted a continuation of the inner platform c. e is mounted on a framework e2. e2 is mounted on posts e3 which are lixedly mounted in the foundation.

f is an outer platform which is mounted on timbers f, f2 'and f3. and f2 are mounted on posts f4 and f5. f3 are bolted to j" and f2.

g is a rail upon which are mounted double flanged wheels Zz. /L are rotatably mounted in forks ZL. Vehicle carrying rods are fixedly mounted iii-forks Zz and rotatably mounted and connected in pairs by a casting h3. h3 has a bearing on 72,. Fixedly mounted on Zzg are crossing guide bars if.

/L5 are rollers, which are supported and have bearings on a collar ZLG. The collar 72, is fiXedly mounted on h2.

z' is an endless chain having roller bearings z" and at intervals recessed links 2.

Za is an endless chain having substantially U shaped toothed links and at intervals recessed links 7c.

Z, Z, Z2, and Z3 are crossing guide way casings. e5 is bolted to the framework e2. The space between e5 and f3 forms a channel or guide way for the rollers 72.5. e4 is bolted to e5 and supports the chains (Z2, Zc). 2 and 7c are concave at their bases to conform Ato the conveXity of the peripheries of the rims of c and CZ.

Fixedly mounted on the wheel Z is a gear wheel m, which is operatively connected with a pulley a. The driving chain z' is mounted around the wheel CZ between the flanges Z and Z2 and around a similar wheel not shown on the drawings. Between these wheels z' is supported by et. z' engages with and drives the chain Z2. 7c is mounted similarly to z' around the wheel o and around a wheel not shown on the drawings. The concave portions of i2 and Za receive the vehicle carrying rods h2. The rail g is so positioned that the vehicle carrying rods h2 will engage at their pitch line with the recessed links 2 and Zc, except at and near the crossing point of the rails g, where the vehicle carrying rods are within the pitch line of the recessed links. The crossing guide bars Zat are so positioned as to pass through the guide ways formed by crossing guide way castings Z, Z, ZL and Z8.

Power being applied to the pulley a, the wheel Z) is revolved and carries with it the chain c' which propels the chain Zo and the wheel c. The vehicle carrying rods ZL2 being propelled by the chain z', upon reaching the engagement point of the chains z' and 70 pass from a recess 2 to a recess 7c and vice versa, and are carried by both chains around Wheels similar in construction to 0 and Z and back to the point of startino. lVhile I show the chain z' as a driving chain, and c as a driven chain, it is obvious that may be the driving and z' the driven chain.

In Fig. 6, I show a chain z' as it may be used in connection with a recessed gear Wheel h2. This recessed gear Wheel I do not claim as my invention, it being the invention of Hermann Hill, and fully shown in his Patent No. 879,872, issued February 25, 1908.

While I have shown my invention propelled by gear Wheels from a source of power outside of the machine, it is obvious that it may bc propelled by motors mounted on one or more of the trucks.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent is:

l. In a chain gearing and spacing mechanism, a driving chain and a driven chain constantly engaged and vehicle carrying rods, both chains having recesses receiving` the rods 2. In a chain gearing and spacing mechanism, endless chains operatively engaging With'each other and vehicle carrying rods, the chains having recesses receiving the rods.

3. In a chain gearing and spacing mechanism, an endless chain, a toothed Wheel and.

vehicle carrying rods, the chain and Wheel being so constructed and mounted as to operatively engage with each other and having recesses receiving the rods.

l. In a chain gearing and spacing mechanism, a chain having toothed links, a chain adapted to engage with the teeth of said toothed links and vehicle carrying rods, both of said chains having recesses receiving the rods.
