SPECIFICATION forming part of Letters Patent No. 703,801, dated July 1, 1902.

Application filed October 23,1901. Serial No. 79.642. No model.) l

Be it known that I, CHARLES LOQFF, Jr., a citizen of the United Statesfand a resident of the city of New, York, borough of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvelnents in Merry-Go-Rounds, of which the following` is a full,clear, and exact de-. scription. l i

The object of the invention is to provide a new and improved merry-go-round arranged to give the seats a uniform up-and-down motion and without requiring much driving power.

The invention consists of novel features and parts and combinations of the same, as' will be 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 cor'- responding parts in all the figures.

Figure I is a plan view of the improvement with parts in section.. YFig.` 2is a sec.- tional side elevation ofthe same,'and Fig?)v is a transverse section of the same on the line 3 3 of Fig. 2.

On the usual center post A is mounted toVv rotate the frame B, carrying in its overhead rock-shafts C, each carrying at its inner end a cam-arm D, provided with a friction-roller E, traveling in a cam-groove F of a cam F, secured to the center post A. The outer portion of each rock-shaft O is provided with transversely-extending double arms G, each carrying at its free end a supporting-rod H, supporting a seat I of the usual form, and the lower end of each supporting-rod H is pivotally connected with a link J, fulcrumed on a bearing K, attached to the platform L of the revoluble frame B, the said link J preferably extending rearwardly directly under the seat. Each link is provide` with a step J' to permit persons to conveniently mount the seat. v

Short or auxiliary rock-shafts C' alternate with the main rock-shafts O and are likewise journaled on the overhead portion of the frame B, and the said shafts O are rocked from and in unison with alternate shafts C,

. seats I.

`the seats I', extending midway between a pair of seats I, as plaiulyindicatedin Fig. 1. Each seat I moves iu an opposite direction to the seats I, between which it is located. The lower ends of the seats I are guided by VVlinks K, the same as the supporting-rods H.

When the merry-goround is in use and the frame B is revolved in the usual manner around the center post A, then the rock-shafts O and O are carried along, and the fricti0nrollers E of the4 cam-arms D, traveling in the groove F', impart a rocking motion to the shafts O, so that the double arms Gswing up and down, and thereby cause an up-and-down movement of the supporting-rods H and the By having the connection between the rock-shafts O and O a like up-and-down movement is given tothe supporting-rods H' Vand seats I.

By reference to Fig. 3, it will be seen that when the shafts O rock in one direction then vone set of seats I moves downward while the other set moves upward, and when the shafts -O rock in the opposite direction then the motiony of the sets of seats is reversed. The seat I' in alinement with a set of seats I rocks in the opposite direction to the seats I in the The links J are arranged in alinement with n the arms G, so as to givea-steady movement to the supporting-rods H. l Having thus described my invention, I claim as new and desire to'secure by Letters Patent-- A a..

l. A merry-go-round vhaving a revoluble frame, a rock-shaft-journaled on the said frame and provided at one end with a camarm and at the other end with an arm for supporting a seat, a fixed cam engaged by the IOO said cam-arm to cause a rocking motion of the rock-shaft on revolving the said frame, short auxiliary rock-Shafts also journaled on the frame and provided with arms connected by a link with an arm on the 'Iirst-named shaft, and arms for supporting seats carried by the auxiliary rock-shafts, as set forth,

2. A merry-go-round having a revoluble frame, rock-shafts journaled on the said frame and extending in a radial direction, supporting-arms on the outer end of the roekshafts, seat-rods carried by the said supporting-arms, guide-links pivoted to the said seatrods and extending rearwardly under the seat, the said guide-link being fulcrumed on the platform of the revoluble frame, a Camarm on the inner end of each rock-shaft, and

guide-links pivotally connected with the seatsupporting rods and fulcrumed on the frame, cam-arms secured on the inner ends of the .said rock-shafts and each carryingafrictionroller at its free end, and a cam secured on the said center post and provided with a groove engaged by the said friction-rollers, as set forth. A

4. A merry-go-round having a revoluble frame, rock-shafts jou rnaled on the said frame and extending in a radial direction, supporting-arms on the outer ends of the rock-shafts, seat-rods carried by the said supporting-arms at the free ends thereof, guide-links pivoted to the `said seat-rods and pivotally connected with the revoluble frame, the said guidelinks bein;r each provided with a step, a cam-arm onthe inner end of each rock-shaft, a fixed earn engaged by the said cam-arm, short auxiliary rock-shafts connected with and rocked from the said 'first-named roekshafts, su pporting-arrns on the said auxiliary rock-shafts, and seat-rods held von the lastmentioned supporting-arms, as set forth.

5. A merry-go-round having a revoluble frame provided with a platform, rock-shafts journaled on the said frame and extending in a radial direction, supporting-arms on the outer ends of the rock-shafts, seat-rods carried by the said supporting-arms, seats supgaged by the' said cam-arm, short auxiliary rock-shafts connected with and rocked from the said first-named rock-shafts, supportingarms `on the said auxiliary rock-shafts, and seat-rods held On the last-mentioned supporting-arms, the last-mentioned seat-rods and their seats being in alinement with the seatrods and seats rst mentioned, as set forth.

6. A merry-go-round, comprising a revoluble frame, rock-shafts journaled on the frame and extending in a radial direction, supporting-arms On the outer ends of the rock-shafts, seat-rods carried by the said supporting-arms, seats supported thereby, means for imparting a rocking motion to the rock-shafts on revolving the said frame, short auxiliary rockshafts alternating with the main rock-shafts, supporting-arms on the said auxiliar-y rockshafts, seat-rods held on thelast-rnentioned supporting-arms, seats carried thereby, andA links connecting arms on the main rockshafts with arms on the auxiliary rock-shafts, each seat connected with the auxiliary rocloshafts extending between a pair of seats connected with the main rock-shafts and moving in an opposite direction to the seats between which it is located, as set forth.
