CMBINAI'ION MERRY-GO-ROUND AND TEETER.

'Go-Rolin and Toeter, of which the following tical movement o is a speciiicatiQn- 'llus invention relates to an 'amusement device in which are combined the rotating action of the merry-go-round and the verthe sees'aw; and the object of the invention is a device of this character 'adapted` for the use of children and in which the riders can motion in combination alternate up-and-down m vement by of suitable levers andratc ets. The inventionv consists of `a suitable base upon which is pivctally mounted a sweep, and upon thebase is carried a ratchet, 'and pivot-arms are provided which are adapted to engage the ratchet, the said -arms being produce the rotary with the vertical actuated by suitable levers and links, and, as the ratclietis fixed, while the sweepz 'tos which the operating-levers are pivoted is free to turn, a rotary motion will begiven to the sweep.

wrought iron or steel, and j ournaled upon the same is a sweep 4. This sweep I prefer to construct in sections, each section consisting of two parallel timbers spaced apart so that a slot 5 will be left between them, and the timbers also incline upwardly from their outer ends to the pivot-pi-n, and -at the point ofconnection o secured together by a metal casting which is provided with a cap 6, and acasting-socket is provided in the castingand. ca to receive the pin 3, so that -the weight ci).

adjustable seats 7, which exten downwardly and inwardly 5 'and are held tothe swee bolt 8, which passes througli the standard 7 and vertically through the slot 5 and on which .is threaded a' nut 9, which bears upon the t'op of the sweep. A-sto pin 10 is car.- ried b each ofthe standar s 7 and bears upon t e under side of the sweep. 'Upon' the upper end of each of the seat-standards 7 is aced a seat 11, and it'will be obvious that so that the position of the'seaft with respect to the pivot-pin can be varied. A The'inventio'n consists in the novel fea'- .tures of construction hereinafter fully de- To further brace the arts, a truss 12 is con? nected to the under si es of the sweep adjacent the meeting point of'the two sections andv overlapping-the said point, and the truss 12 is longitudinally slotted, 'as shown at 13, and tov permit free playcand rotation of-the sweep' upon and about the pivot 3. T o'hold the sweep in a horizontal osition when not in use, a plate 14 is place u' and springs 15 are secure at 'their' inner ends to the said plate and attheir outer end s' to the under face of the truss '12. f

To provide for the rotation of the sweep about .the pivot-point 3, arms 16,'and 17-.are pivoted upon the pin 3 at their innerends, and, as shown in 5, thearm 17 overlaps areduced end ortionof the arm 16 and also pro'ects slight y into'n-undercut 18, formed in t e arin 16 adjafc'ent the pivot-pin 3. This prevents the inner end of the arm 17 from' riding up upon the sides of the pivot-pin 3l I have shown -tl i provided upon through the slotl by means of a the two sections they are the sweep Abears upon the top of the said pin. I als jiprovide Qn'the pivot-pin 3 f IOO ie arms-16 and .17 as being-f their under faces withawlsy 19, which engage theteeth o Etheratc et 2 5but it will be understood, of'iie,that the ratchet-teeth can be omittedand the device operated by friction.

To operate the arms and 17 Ievers. 20

'80 .l by this manneroi securing the seat that it is adjustable along the sweep,

are ivotally connected at their lower ends to t e seat-standards 7 and provided with suitable horizontal handle-bars 21 at their upper ends, the said levers projecting -upwardly through the slot and within easy reach of a child sittin upon the adjacent Each lever 2() is connected to one of the arms 16 17 by means of links 22 23, which links overlap and are fastened together by a pin 24, the overlapping ortions of the links 22 and 23 being provide with a plurality of erforations and also with guideoops 2 his construction permits of the length of the links being adjusted as is necessary to allow for sliding adjustment of the seats 11 along the swee 4,and it will be obvious' that by allowing fier adjustment of the seats the seats can be so positioned with re spect to thejpivot-pin 3 that a difference in weight of the children using the device can be compensated for.v j

Adjacent the lowerends of the seat-standard 7 are' laced transverse pins 26, extending upon eac side of the standard, which pins serve as foot-rests. V

In operation the device can be used either as la seesaw or as a combined merry-goround and seesaw b operating the lever 20, and the operation o these levers remove the arms 16 and 17 in one direction, the pawls 19 slidin upon the ratchetteeth,and when the lever is pulled in the opposite direction the pawls 19 will hold and the sweep will be given a rotatory movement. This will not only cause the sweep to revolve, but will also give a downward tendency `tothe end of the sweep from which the lever is being operated, and on account of this arrangement when one operator .is in a higher plane than the' other and pulls upon his lever the action not only. produces a circular movement of the sweep, but also gives a downward movement to his end of the sweep, and in this manner by alternately operating the ,levers 2l) a' combined rotatory and wavemotion may be oh tained, or when only one o crater works oneI of the levers the repeate operation of the saidl lever will cause a rotation sullicicntly rapid so that the centrifugal force will hold the machine steady, or that is in a comparatively horizontal plane, and this alone will compensate for a considerable dillcrcnce in weight of the two riders without changing the adjustment of the seats.

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

1. A device of the kind described comprising a central pivoted sweep, longitudinal slotted, a seat-standard extending throng said slot and slidably adjustable alon said slot, a seat carried by the said standar a l'ever pivotally connected at its lower end to the said standard and also projecting up'- wardly throu h the said slot, and means connected to saidlever for rotating the sweep.

2. The combination with a pivoted sweep, longitudinally slotted, a seat-standard extending in said slot, and slidably adjustable therein, a seat upon the standard, a fixed disk concentric with the 'pivot-point of the sweep, an arm pivoted upon said disk, a lever ivoted to the seat-standard, adjustable inks connecting the lever to the arm and means carried by the arm adapted to engage the disk.

3. A device of the kind described comprising a base, a disk therein, apivoted pin on the disk, a sweep pivotally resting upon the said pivot-pin, seats adjustably mounted upon the sweep, arms pivotally mounted upon .the pivot-pin, means carried by the arms adapted to engage the periphery of the disk and means operatable'from the seats for partially rotating said arms in opposite directions. i

` 4. A device of the kind described comprising a base, a pivot-pin, a ratchet, a sweep pivotally mounted upon the ivot-pin adjacent the ratchet, pawls carried l; the armsadapted to slide uponthe ratchet in one direction and to hold the arms stationary during a pull in the opposite direction, scat-standards slidably adjustable in the slot of th(` sweep, seats carried by said standards, a lever pivotally connected to each Aol" said standards, and adjustable links connecting 'said levers to the said arms, respectively, als :1nd for thc purpose sel forth.
