Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 279 words
A pick-up rake comprising a rake handle having a main rake head secured to its lowermost end, and an auxiliary rake head assembly including an auxiliary rake head having a plurality of tines carried by the rake handle and selectively movable from an upper storage position enabling normal raking to a lower position enabling leaves, grass and debris to be gathered and held between the two rake heads, the auxiliary rake head assembly also including a shaft pivotally secured at its upper end to a handle sleeve which is slidable along the rake handle, the upper ends of the tines of the auxiliary rake head being secured closely together on a tine-plate which is secured to a shaft sleeve freely slidable along the shaft, the tines being slidably movable through a tine-guide which is fixedly secured to the lower end of the shaft, and a pair of links pivotally interconnecting the rake handle and the shaft sleeve, full upward movement of the handle sleeve along the handle moving the auxiliary rake head to storage position and downward movement moving the auxiliary rake head to gathering position, in gathering position the shaft sleeve being downwardly positioned with respect to the shaft to extend the tines through the tine-guide spreading the lower ends of the tines of the auxiliary head, and in storage position the shaft sleeve being upwardly positioned with respect to the shaft to draw the tines through the tine-guide to bring the lower ends of the tines together, and a flange on the lower end of the rake handle to receive and hold the lower end of the shaft when the auxiliary rake head is in storage position.
Claim 2
Dependent Claim 279 words
A pick-up rake comprising a rake handle having a main rake head secured to its lowermost end, and an auxiliary rake head assembly including an auxiliary rake head having a plurality of tines carried by the rake handle and selectively movable from an upper storage position enabling normal raking to a lower position enabling leaves, grass and debris to be gathered and held between the two rake heads, the auxiliary rake head assembly also including a shaft pivotally secured at its upper end to a handle sleeve which is slidable along the rake handle, the upper ends of the tines of the auxiliary rake head being secured closely together on a tine-plate which is secured to a shaft sleeve freely slidable along the shaft, the tines being slidably movable through a tine-guide which is fixedly secured to the lower end of the shaft, and a pair of links pivotally interconnecting the rake handle and the shaft sleeve, full upward movement of the handle sleeve along the handle moving the auxiliary rake head to storage position and downward movement moving the auxiliary rake head to gathering position, in gathering position the shaft sleeve being downwardly positioned with respect to the shaft to extend the tines through the tine-guide spreading the lower ends of the tines of the auxiliary head, and in storage position the shaft sleeve being upwardly positioned with respect to the shaft to draw the tines through the tine-guide to bring the lower ends of the tines together, and a flange on the lower end of the rake handle to receive and hold the lower end of the shaft when the auxiliary rake head is in storage position.
Claim 3
Dependent Claim 93 words
A rake according to claim 1, including a locking arm to secure the sleeve, when in its lowermost position with respect to the shaft against sliding movement along the shaft, the locking arm being pivotally carried by the shaft sleeve and engaging in a hole in the shaft during upright orientation of the rake handle during gathering, the locking arm pivoting from engagement in the hole upon horizontal orientation with the auxiliary rake head uppermost enabling movement of the shaft sleeve along the shaft to position the auxiliary rake head in storage position.
