COMBINED SEESAW AND MERRY-GO-ROUND Filed June 12, 1930 2 Sheets-Sheet l April 18, 1933. F. M. JACOB COMBINED SEESAW AND MERRY-GOROUND Filed June 12, 1930 2 Sheets-Sheet 2 comm s seesaw AND IfIEEBR Y-GO-ROUNDQW rMy'jinvention "relatesffto an improvement in a combined see-saw. and merry-gmrou'nd. jflh efobject is to proyide" asee-saw and nierrygo-round which is simple and sturdy inconstruction and which is capable of -be ing used either as a permanent or as a portable fiXture, J j

A further objctof my invention is to provide asee-saw. and merry-gofround which may be'adjusted for use by children of different sizes and weights. .A see-saw of my construction may also be used by two or more persons, oneteeter board being folded out of the way when not in use. I l V @In the accompanying drawingsr a .Fig. 1 is a perspective view of'the device, showing one teeter board in position foruse, theother being broken away-p f Fig. 2 is a plan view; V 3 is avertical section of teeter boards; V

Fig. 3a is a fragmentary view of the teeter board support showing one means of fastening the same to the ground F ig. 4 is an enlarged sectional detail of the inner end of the teeter board showing the board in position for use;

Fig. 5 is an enlarged sectional detail of the inner end of the teeter board, showin the board folded up out of the way Fig. 6 is a section on the line 66 of Fig and p Fig. 7 is a detail of one of the teeter partly in cross-section. p v

The column 2 of the see-saw'is fastened to and supported by the base '4. The sleeve 6 is rotatably mounted on the'column 2 and held between the lower bearing collar 8 and the upper bearing collar 10. Interposed be-g tween these bearing collars 8 and 10 and 'the sleeve 6 are the ball bearings 12. r

On the revolving sleeve 6; the pivoted. teeter arm supports 14 are mounted bymeans through one set I arms,

i 4 of the pins 16 projecting from the sleeve 6.

The teeter arms 18 are pivotally attached to the teeter arm supports 14 by meansof the bolts 20 and are held in the desired position by the hand bolts 22. V I

As shown in Fig. 7, the teeter arms 18 are made of solid material at'the inner'ends,v

Beneath ;the handrail and 0 at a distance furthelnaway from the seat is a metal strip bent to. form a foot rest 36, the foot restbeing secured. tothe arm 24lby 7 means of a bolt 38.
