Abstract
Abstract A pair of rakes, each provided with a plurality of tines projecting in a substantially horizontal direction. The rakes are mounted for movement in a substantially triangular path between an advanced position and a retracted position spaced from one another in the direction of elongation of the tines, and also between an upper and a lower level while they are in the advanced position. Movement of the rakes is controlled so as to assure that whenever one of the rakes is in the advanced position and at the upper level another rake will move to the advanced position and to the lower level before the first-mentioned rake moves away towards the retracted position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
134 words
In an apparatus of the character described, in combination, a pair of rakes each elongated in one direction and having a plurality of tines projecting in a substantially horizontal other direction; first means mounting said rakes for movement in a substantially triangular path between an advanced position and a retracted position spaced from one another in said other direction, and between an upper and a lower level while in said advanced position; and second means operative for controlling the movements of said rakes in a sense effecting movement of one of said rakes to said advanced position and lower level while the other of said rakes is in said advanced position and upper level, and for thereupon effecting movement of said other rake from said advanced position and upper level to said retracted position.
Claim 2
Dependent Claim
134 words
In an apparatus of the character described, in combination, a pair of rakes each elongated in one direction and having a plurality of tines projecting in a substantially horizontal other direction; first means mounting said rakes for movement in a substantially triangular path between an advanced position and a retracted position spaced from one another in said other direction, and between an upper and a lower level while in said advanced position; and second means operative for controlling the movements of said rakes in a sense effecting movement of one of said rakes to said advanced position and lower level while the other of said rakes is in said advanced position and upper level, and for thereupon effecting movement of said other rake from said advanced position and upper level to said retracted position.
Claim 3
Dependent Claim
66 words
In an apparatus as defined in claim 1, said first means comprising a pair of shafts, a pair of arms mounted on said shafts and connected with the respective rakes for movement about said shafts in a sense effecting displacement of said rakes between said advanced and retracted position, and cam means acting upon said arms for effecting movement of the same about the respective shafts.
Claim 4
Dependent Claim
33 words
In an apparatus as defined in claim 2, said first means further comprising displacing means for displacing said rakes between said upper and lower levels while said rakes are in said advanced position.
Claim 5
Dependent Claim
52 words
In an apparatus as defined in claim 3, said displacing means comprising additional cam means each having a cam track, rods extending in at least substantial parallelism with the respective arms and articulately connected with the respective rakes, and a cam follower on each rod and engaging one of said cam tracks.
Claim 6
Dependent Claim
17 words
In an apparatus as defined in claim 4, wherein each cam follower is a cam follower roller.
Claim 7
Dependent Claim
47 words
In an apparatus as defined in claim 4, further comprising a pair of double-armed levers pivotably mounted on the respective shafts and each having two arms, one of said arms being articulated to one of said rods and the other of said arms conveying said cam follower.
Claim 8
Dependent Claim
33 words
In an apparatus as defined in claim 6, said one arm comprising a projecting pin, and said rods each having a longitudinal slot in which the respective pin is turnably and slidably engaged.
Claim 9
Dependent Claim
42 words
In an apparatus as defined in claim 1, said rakes being adapted to support objects thereon; and further comprising ejecting means for ejecting such objects from the respective rakes when the same are in said advanced position and at said upper level.
Claim 10
Dependent Claim
98 words
In an apparatus as defined in claim 8, said ejecting means comprising an ejecting member mounted above said rakes and having a substantially vertical contact face, said ejecting member extending downwardly between respective tines of the rake respectively located in said advanced position and at said upper level, and a cylinder and piston unit acting upon said ejecting member in a sense displacing the same in said other direction between a first position in which it is located between the respective tines and a second position in which it pushes objects resting on said tines off the same.
Claim 11
Dependent Claim
21 words
In an apparatus as defined in claim 9, wherein said cylinder and piston unit is a hydraulic cylinder and piston unit.
Claim 12
Dependent Claim
16 words
In an apparatus as defined in claim 9, wherein said ejecting member is of bifurcated configuration.
Claim 13
Dependent Claim
97 words
In an apparatus as defined in claim 9, said ejecting means further comprising securing means securing the cylinder of said unit for pivotal displacement in substantially vertical direction between an upper and a lower location, and securing said ejecting member on the piston of said unit, drive means acting upon said cylinder in a sense displacing the same between said location, and a coordinating unit coordinating displacement of said cylinder to said second position with its displacement to said lower location, and displacement of said cylinder to said first position with its displacement to said upper position.
Claim 14
Dependent Claim
23 words
In an apparatus as defined in claim 10; and further comprising a counter operatively connected with and controlling operation of said coordinatinG unit.
