Abstract: An improved toy phonograph of the type in which a pickup arm is pivoted at one end and is engageable with a playing surface of a first phonograph record rotatably mounted on one side of the turntable, with a first spring urging the pickup arm toward the periphery of the phonograph record and with a first speaker cone means resiliently mounted on the housing of the phonograph record above the pickup arm and having a lift bar means removably engageable with the pickup arm in sound reproducing contact, includes an arrangement for resiliently pressing the pickup arm into engagement with the phonograph record for reproducing recorded sounds from the phonograph record playing surface during rotation of the turntable, with this pressing arrangement substantially uniformly resiliently biasing the lift bar against the pickup arm with a substantially uniform biasing force for exerting substantially uniform pressure on the pickup arm needle throughout the entire path of travel circumscribed by the needle across the phonograph record playing surface from the periphery towards the center during such sound reproducing engagement. This pressing arrangement comprises a bifurcated spring member resiliently pressing against the lift bar at a pair of spaced apart positions therealong and further includes another spring resiliently pressing against the bifurcated spring member for enabling adjustment of the biasing force provided by the bifurcated spring member as a result of adjustment of the biasing force of the other spring. This improved toy phonograph may be used in either a single play or continuous play arrangement with the substantially uniform pressure on the lift bar ensuring positive shut-off in the single play arrangement.
