To @ZZ whom t may concern: Y Y

Be it known that I, FRANK C. PREsooTT, a citizen of the United States, residing at Can-v ton, in the county of Lawrence and State of l New York, have inventeda new and useful '15 parted to a boat-shaped carriage as the latter is moved in a circular path around the stationaryspindle. 5 i

struct and arrange the parts in a novel'way' zo with a view to making ,them brace or 'stayl each other mutually, thus contributing to the strength and stability of the structure..

vA further object of the invention isto im-A prove the machine lin various ways, so as to simplify its construction, promote its efficiency, and enable ready access to be had to all the various parts for inspection and repairs.

With these ends in view my invention con- 3o sists in the combination of a stationary spin-Y dle, a revoluble carrier mounted loosely on the spindle to rotate thereon, a revoluble head also fitted loosely on andbearing upon the spindle and connected rigidly with the rev- 3 5 oluble carrier, a series of rocking mast-arms pivotally mounted on the head and extending radially therefrom and from the spindle, a boat or carriage suspended at its opposite ends from Van adjacent pair of mast-arms, a

4o series of radial shafts mounted on the revoluble4 carrier and each operatively connected at one end with the rocking mast-arm to impart vibratory movement thereto in a vertical plane as the carrier and head are rotated in vices, which will be hereinafter more fully described and claimed.

To enable others to understand my invention, I have illustrated the preferred embodiment of the same in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a plan view of a roundabout or carousel constructed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is an enlarged vertical sectional elevation through the revoluble carrier and head, with the rockingmast-arms broken away and showing the operative elements of the carousel. Fig. 4. is a detail perspective view vof the revoluble head to show the construc- `tion thereof. A further object ofthe invention is to con#V Fig. 5 is a transverse sectional view through the central part of the carousel onv the plane indicated by the dotted line 5 5 of Fig. 3, with therevoluble carrier broken away in part. Fig.' 6 is a detailview of one of the crankdisks, showing an adjustable wrist-,pin therein. Fig. '7 is a detail sectional View illustrating the manner of attaching the connecting-rods to the disks.

Like numerals of reference denote corresponding parts in all the figures of the drawtion I employ a base l of suitable diameter,

which is to be placed in or upon the ground and to be'anchored securely in place in any suitable manner which may be supplied by a skilled mechanic. To this base 1 is secured a vertical spindle 2, which is united rigidly and solidly to the base. This spindle projects upwardly a suitable distance from the base, so as to pass entirely through the operative parts of the roundabout or carousel, and the upper part of this spindle is reduced in diameter to form a stem 3 and an annular ledge or shoulder 4. at a point between the major length of the spindle and the stem 3 thereof.

A master-gear 5 is attached solidly and rigidly to the spindle in a suitable way at a point some distance above the base l. This mastergear may be either solid, as shown by the drawings, or it may be made in sections in any preferable manner to provide for its ready assemblage around and its attachment to the spindle 2. The peripheral edge of this iiXed IOO master-gear has a series of bevel gear-teeth which extend continuously around the said gear 5, and with this master-gear meshes a series of beveled gear-pinions 6, attached to the inner ends of the series of radial shafts 7. These radial shafts are journaled in bearings S 0 on the revoluble carrier 10, the said carrier being loosely fitted to the spindle and equipped with ball-bearings to ride upon the base in order to insure a free easy movement of the revoluble carrier on the spindle and the base.

In the preferred embodiment of my revoluble carrier it comprises two concentric rings 11 12, a base-plate 12, a series of radial spokes 13, and an annular driving rim or wheel 14, all of said parts being united solidly and rigidly together to present a substaut-ial structure. The rings 11 12 are arranged one within the other concentric to each other, and the base-plate 12 is arranged below the inner ring 1l in a horizontal plane parallel to that of the inner ring. The radial spokes 13 have their inner ends fitted between the inner ring 11 and the base-plate 12, and these spokes extend beneath or through the outer ring 12, so that the outer ends of the spokes may be attached rigidly to the driving wheel or rim 1i. The spokes are attached to the baseplate, the inner and outer rings, and the driving rim or wheel by bolts, or in any suitable way, and the parts of the carrier are thus united solidly together to insure their rotation with the driving rim or wheel 14. This rim or wheel 14 may be provided with a grooved periphery 15 to receive a driving belt or cable, (not shown,) but the rim or wheel may be geared to a motor or engine in any suitable way-as, for instance, by toothed gearingwithout departing from the spirit of my invention. The base-plate 12L of the carrier is fitted loosely to the spindle 2, and said.

baseplate has a ball-bearin g or antifrietionbearing 16 upon the base 1 to insure free motion to the carrier. The ball-bearing 1G may be of any suitable construction.

The concentric rings 11 12 of the carrier extend a suitable distance above the horizontal plane of the spokes, the baseplate, and the driving-rim, and on the upper edges of these concentric rings are provided the bearings S 9 for the radial shafts 7. These bearings 8 9 may be of anysuitable construction, and the bearings 9 are arranged in alinement with the bearings 8 radially with respect to the revoluble carrier to insure proper support to the radialshafts. The revoluble head 17 of the roundabout or carousel is placed loosely on the reduced stein 3 of the stationary spindle to ride upon the annularshoulder or ledge i of the spindle. This head may be east in a single piece of metal or it may be constructed in sections to facilitate its application to the stem. Vhen made in a single piece, as shown by the drawings, the head is provided at its peripheral edge with an annular fiange 1S, which rises a suitable distance above the plane of the web or disk of the head, and it is,furthermore, provided with a central hub 19, fitted loosely on the spindle and constructed to receive the ball-bearings 20, by which the head is enabled to ride upon the annular shoulder or ledge 4 of the spindle 2. The annular fiange of the revoluble head is slotted or notched at suitable intervals to provide radial openings or slots 21 in the periphery of the head, and through these radial slots 21 extend the inner ends of the mast-arms 22. A series of these mast-arms 22 is provided in my roundabout or carousel to sustain a series of boats or carriages 23, and said mast-arms and the boats or earriages are arranged to be carried in a horizontal circular path bythe revoluble earrier, and at the same time the mast-arms and the boats or carriages suspended therefrom are given a vibratory and rocking motion in a vertical direction, whereby the boats or carriages have imparted thereto a wave-like motion simultaneously with the rotary motion of the carrier.

The mast-arms are pivotally attached at their inner ends to the revoluble head 17 in a suitable way. I have shown in the preferred embodiment of my invention a pair of bearing-blocks 24, fastened rigidly to the top face of the head on opposite sides of one of the radial slots or notches therein, and between the pair of bearing-blocks is fitted one of the radial mast-arms 22. Through the bearingblocks and the mast-arm fitted between them is passed a horizontal bolt or arbor 25, on which the mast-arm is free to rock or turn in a vertical direction, and thus the mastarm is pivotally attached to the revoluble head in a manner to secure strength and stability at the pivotal joint, because the bearingblocks provide firm solid supports of the extremity of the mastarm, and the latter is adapted to rest upon the head and to be confined by the adjacent ends of the notched or eut-away flange 18 of the head. It will be understood that each mast-arm is attached to the head 17 in the manner described.

Each mast-arm is constructed in a peculiar way to constitute a truss, with a View to securing the necessary strength and stability to the parts. An upright brace-arm 2G is attached to each mast-arm at a point intermediate of its length, and the mast-arm and its brace are reinforced by the employment of angle-irons 27,which are fastened to the mastarni and its brace at the juncture of said parts. Between the brace and the free eX- tremity of the mast-arm is stretched a stayrod or cable 2S,which is provid ed with a turnbuckle or other suitable take-up device, (indicated at 29.) This construction provides a truss for the mast-arm to enable it to withstand the weight and strain of the boat or carriage and the passengers therein, and the take-up device may readily be adjusted at any time to insure the necessary rigidity and stiffness of the mast-arm.

IIO

To make the mast-arms balance each other and thus secure an equal distribution of the load on the carousel, I couple them in pairs and arrange the devices for imparting vibratory motion theretoto work in unison. In the drawings I have shown the roundabout or carousel With a series of six mast-arms and their complemental boats or carriages, and the mast-arms are arranged radially with respect to the revoluble head and the spindle. The pair of mast-arms at diametrically opposite points of the revoluble head is coupled by one or more connecting-rods 30, and thus I have three pairs, or six mast-arms, connected by the rods or stays. The rods or stays are attached at their extremities to the brace-arms'26 of the mast-arms, and said connecting rods or stays 30 are arranged to pass on opposite sides of the stem of the spindle 2 in a manner to avoid interfering with each other as the mast-arms are rocked in vertical directions on the rotary motion of the carrier 10.

' tached centrally and rigidly to the outer extremity ofits radial shaft, and said disk has a wrist-pin 34, to which is loosely connected the lower end of the pitman 33. The upper end of the pitman is loosely attached to its mast-arm in a manner to compensate for the orbital motion of the wrist-pin on the crankdisk without wrenching or straining the connection of the mast-arm to the revoluble head 17 and to allow the mast-arm to move or oscillate Vin a vertical direction. The connection between the pitman and the mast-arm is in the nature of a universal joint, (indicated at 35,) and in the embodiment of the joint shown in the drawings I have illustrated a socket-plate 36, attached to the lower side of the mast-arm, and a stem 37, fitted loosely in the socket-plate and attached to the upper extremity of the pitman.

rIherevoluble head 17 and the revoluble carrier 10 are coupled together to insure their simultaneous rotation, and as one means for thus coupling the head and carrier together I employ a series of stays or rods 38, which are arranged to cross' each other and which have their ends fastened, respectively, to the revoluble head and to the outer ring 12 of the carrier. The attachment of the braces or stays 38 to the carrier and head may be effected in any suitable way-as, for instance, by eyebolts-and each stay or rod 38 is provided with a turnbuckle or othertake-up def vice for straining the rod or stay to secure the necessary parallel relation of the head and carrier, and enable the parts to rotate freely on the spindle 2. To prevent the head from about the spindle.

sagging under the weight or load of the passengers in the boats or carriages suspended from the mast-arms attached to the revoluble head, I provide the upright braces 39 between the head 17 and the inner ring 1]. of the carrier. These upright braces are arranged at suitable intervals from each other, and any desired number of such braces may be used.

The boat or carriage 23 is attached to the proper mast-arm in any suitable way; but I prefer to loosely connect the boat or carriage to a pair of the mast-arms, so it will have a swaying motion as the carrier and head rotate I prefer to construct the part 23 in the form of a boat to be suspended at its bow and stern from two adjacent mastarms; but it will be understood that I do not strictly limit myself to the particular form of boat shown, because the carriage for the passen gers maybe of any suitable style or form which may be preferred. The boat or carriage has one or more seats for the passen-V described as follows: Motion is imparted to the driving wheel or rim 14 of the carrier, and

as the head 17 is rigidly coupled to the carrier' the head and carrier rotate simultaneously to move the mast-arms, vthe boats or carriages suspended therefrom, and the radial shafts in a circular path around the stationary spindle. As the shafts are carried with the carrier the bevel-gears on the inner ends thereof mesh with the master-gear, and the radial shafts are thus rotated on their axes to impart rotary motion to the crank disks or wheels. These crank disks or wheels operate to reciprocate the pitmen, which in turn oscillate or rock the mast-arms and the boats or carriages IOO IIO

suspended therefrom, and thus the boats or carriages are given a twofold motion rin a positive manner-z'. e., a horizontal rotary motion with the carrier and head and a vertical oscillating motion by the connections between the `mast-arms and the radial shafts.

The mast-arms being connected in pairs, the Wrist-pins on opposite crank-disks are set on opposite centers, so as to impart to one mastarm of the pair an upward motion, while the other mast-arm of the same pair is given a downwardmotion, and thus the mast-arms move in unison to enable them to be coupled in pairs without breaking the connecting rods or stays, so that the load in the pairs of boats or carriages is equally distributed.

Various changes in the form and yproportion of parts and details of construction may be made without departing from the spirit or sacricing the advantages of my invention.

In Fig. 6 of the drawings I have shown in detail one ofthe crank-disks 32, and this disk is constructed to carry the crank or wrist pin 34 in a manner to provide for the radial adj ustment of said pin toward or from the cenmast-arms at points beyond their fulera to ter of the disk. This object may be attained by anysuitable construction of the parts, and the purpose of the adjustable crank or wrist pin is to vary the throw or movement of the pitman attached thereto. This adjustable wrist-pin is to be moved in unison with the adj ustment of the turnbuckles of the rods 30, which couple the pairs of trussed mast-arms.

I prefer to build up or make in sections the belt-wheel and the rings of the carrier in the practical construction of my carousel; but I may make each part in a continuous piece, as shown by the drawings.

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