SPECIFICATION forming part of Letters Patent No. 368,652, dated August 23, 1887.

Application tled May 20, 1887. Serial No. 238,881. (No model.)v

.To all whom, it may concern:

Be it known that I, JOHN GLASS, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Seesaws and MerryGo-Rounds, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

Myinvention relates to improvements in seesaws and merry-go-rounds; and it consists in providing a combined seesaw and merry-gd round, as hereinafter described.

My invention relates to the detail and combination of parts, as described,and set forth in the claims.

Figure lis an elevation of a seesaw and merry-goround, representing my improvements. Fig. 2 is a like view, partly in section. Fig. 3 is a view in perspective of my invention adapted to a portable stand or base. Fig. 4 is a sectional View of the same.

Similar letters of reference indicate corresponding parts in all ofthe figures of the accompanying drawings.

Letter A represents a postor stand that may be planted on the lawn or elsewhere, on the top of which there is mounted a cast-metal socket, B, the upper end of which terminates in a spherical head or ball-shapeportion, a. About the lower end of 'said socket there is provided an annular groove, a. On the apex of the head a there is a segmental slide, a2, the circle of the under side of the slide to coincide with the surface of the head a, with which a pivotal connection is formed by the rivet a, about which the slide a2 may rotate.

A saddle-piece, C, is provided,having about central thereto a hemispherical socket, at, in which there is provided a semi-annular groove, a5, in the line of the saddle-wings a, the size of said groove to be regulated by the size of the slide a2, over which it will move as the saddle is vibrated over the head. The object of the slide and groove is to prevent a side rocking movement of the saddle and yet allow it to vibrate freely over the head in the line of its length. On the outer ends of the saddle-wings a there are provided downwardly and out` wardly projected lugs al, having pivoted between them a latch, as, and on the top a stud,

a, and from the center of the saddle an upwardly-projected bolt, b9, by which the said plank D is secured to the saddle C. From the center of the saddle, as at b, there is a throughslot, b, in the plank O, adapted to the bolt b, extending longitudinal to b2, and a groove, b3, on the under side extending to b4, in which rests the lug ai.

In. the groove a there is a ring, b5, having trunnions b6 and eyes bl. The said ring a is divided in two parts, said division vbeing central through the trunnions, the two parts being duplicates. Link E has a pivotal connection about the trunnion bc. The side link is provided with an adjustable loop, bs, the free end of which is adapted to pass over the end of the saddlewing a6 and rest on the end of the latch es, and to the eyes b is attached coilsprings F, the louter end of which is provided with a loop, d, adapted 'to pass over the end of the saddlewing d and rest on the latch as.

The seat-plank D has on each end a backrest, Gr, formed of a single piece of wire, and in form substantially as shown, beginning at the front middle section, as at d', and extended outwardly and upwardly to a point designated as cl2, and inwardly to d3 and downwardly to d4, i

thence to the point designated as d', at which point the free ends d5 are secured to the central portion, d', ofthe wire, and at which point the parts are clasped together by metal clasp d about the parts, and by which the rest may be secured to the plank by a bolt, di, about which said rest may be adjusted for a side seat or astride. The seat-plank D may be in two parts, connected by the hinge d10 and secured by the splice'block c u.

It will be seen that the seesaw may be vibrated in any direction over the head a, the slide a2 moving about the pivot c, but can have no rocking side motion. To apply the springs, pass the loops cl over thelatch es. Vith both springs applied the saddle cannot be thrown vfrom the head, making the use of either the seesaw or merry-go round safer for children; or one spring may be dropped down and the seesaw used by one child.

Whether the springs are connected with the saddle or not, my invention may be used as a seesaw or merry-go-round, or both at the same time, as the rotary and vibratory movements may he simultaneous; and to adapt the parts to be used as a merry-go-round for one person,

IOO

the link E may be connected with the saddle, as shown in Fig. 1, the person seated on the opposite end of the plank. Whether this cheekloop or the springs are in use, the ring b5 will revolve about the socket B in the groove a and the groove a5,vibrating over the slide a2 as the ends of the seat-plank rise and fall.

The seat-plank may be adj usted endwise over the saddle to adapt the seesaw to persons of unequal Weight, and secured in such' adjustment by the thumb-screw yb9.

For the purpose of adapting my invention to nursery andpother indoor use, I have provided a tripod for the support of the hereinafter-described seesaw and merry-go-round,con sisting of a central vertical stem, H, preferably of metal pipe, surmounted by the spheri cal or ball-shaped portion a and slide a2, a legsupport, h', embracing said stem H, having anged projections ha, for the reception and support of the legs h4, thesaid legs having a link-connection, h5, with the bottom of the stem H, as shown. The stem H is also provided with a series of perforations, h", and a pin, hl, by which the height of the seesaw and irsrrygo-round may be adjusted.

Having thus fully described the nature and object of my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a seesaw and merry-goround, the combination of the head a, the upper portion of which is spherical, and the upwardly-proj ected slide a2,piv'oted thereto, and a saddle, C, having a hemispherical socket, ai, and groove a5, substantially as shown and described, and for the purpose set forth.

2. In a seesaw and merry-goround, the combination of the/head a, the upper portion of l which is spherical in form, an upwardly-projected pivot, a3, and a saddle, C, having a hemispherical socket, a, and groove a5, said socket, a, and projected wings a6, having on their outer ends latches a8, ring b5, and springs F, substantially as described, and for the purpose set forth.

4. In aseesavsr and rnerry-go-round, the combination, with the standard A, of the socket B, having an annular groove, a', spherical head a, an upwardly-projected slide, a2, a saddle, C, having a hemispherical socket, a4, groove a5, wings a6, latches a8, ring b5, loop E, and seatplank D, substantially as described, and for the purpose set forth. v

5. 'In aseesaw and merrygoround, the combination, with the seat-plank, of the saddle C, having a hemispherical socket, a, groove a5, a spherical head, a, slide a2, standard H, having perforations h6, pin hl, and a tripod having legs h, the upper ends of which are pivotally connected to the support-ring lz', the lower end by a link to the standard H, substantially as shown and described, and for the purpose set forth.

6. In a seesaW and merry-go-round, the combination, With the seat-plank, of the seat consisting, essentially, of a wire or rod bent into shape to form the sides and back of a seat and secured to the plank in rotary adjustment, substantially as set forth.

In testimony whereof I have hereunto hand this 14th day of May, A. D. 1887.
