Abstract
Abstract Mechanism for raising and lowering the press or roof on a mobile stack-forming machine, the mechanism including a fore-and-aft pair of cranks mounted on each side of the machine for vertical swinging movement above horizontally coplanar transverse axes, a longitudinally extending horizontal link connecting each pair of cranks, a vertically extending link connecting each crank with the roof, and means for swinging the first crank in each foreand-aft pair about its transverse axis, the longitudinally extending links serving to simultaneously swing the rear crank in each pair about its axis, and the vertically extending links connecting each of the cranks to the roof serving to raise and lower the roof as the cranks are swung about their axis, the parts being so arranged and constructed that the roof remains level as it is raised and lowered relative to the body of the machine.

Independent Claim
286 words
In a crop-harvesting machine having a mobile frame, a cropreceiving body supported rearwardly on the frame and including a transversely spaced pair of longitudinally extending, vertical sidewalls, crop pickup and delivery means supported on the frame forwardly of the crop-receiving body for picking crop material up off the ground and delivering the same rearwardly to the cropreceiving body, and a roof supported on the body for movement between raised and lowered positions, the roof being operable to compress crop material contained in the body, means for effecting vertical movement of the roof comprising: a pair of front and rear crank members mounted on each side of the crop-receiving body for vertical swinging movement about horizontally coplanar, longitudinally spaced front and rear transverse axes, each crank having first and second transverse pivot members thereon spaced from the transverse axis about which the crank is swingable and from each other, the relative locations of the transverse axis and the first and second transverse pivot members on the cranks in a front and rear pair being substantially identical; a longitudinally extending, horizontal rigid link connecting the first transverse pivot members on the cranks in each pair, each link being operative to maintain a fixed horizontal distance between the first transverse pivot members which it connects, said fixed horizontal distance being substantially identical to the horizontal distance between the front and rear transverse axes about which the cranks are swingable; a vertically extending rigid link interconnecting the second transveRse pivot member on each crank with the roof; and means acting between the frame and one of the cranks on each side of the body for rotating the crank and thereby moving the roof vertically between its raised and lowered positions.

Claim 3
Dependent Claim
78 words
The invention defined in claim 1 wherein each of said crank members is generally T-shaped and includes generally perpendicularly disposed first and second portions, one end of the first portion being mounted on the side of the crop-receiving body for vertical swinging movement, and the other end of the first portion being rigidly connected to an intermediate portion of the second member, the first and second transverse pivot members being disposed on opposite ends of the second member.
Claim 4
Dependent Claim
57 words
The invention defined in claim 2 wherein the second portion of each crank is inclined upwardly and rearwardly when the roof is in its lowered position, and wherein the first transverse pivot member is disposed on the forward end of the portion and the second transverse pivot member is disposed on the rearward end of the portion.
Claim 5
Dependent Claim
81 words
The invention defined in claim 3 wherein the parts are so arranged and constructed that as each crank swings from its position corresponding to the lowered position of the roof to its position corresponding to the raised position of the roof the first pivot member moves through an arc bisected by the transverse vertical plane containing the axis about which the crank is swingable, and the second pivot member moves through an arc bisected by the horizontal plane containing said axis.
Claim 6
Dependent Claim
63 words
The invention defined in claim 3 wherein the parts are so arranged and constructed that as each crank swings from its position corresponding to the lowered position of the roof to its position corresponding to the raised position of the roof the second pivot members moves through an arc bisected by the horizontaal plane containing the axis about which the crank is swingable.
Claim 7
Dependent Claim
84 words
The invention defined in claim 1 wherein the first and second transverse pivot members on each of the cranks is located in relation to the transverse axis about which the crank is swingable so that the first pivot member is below and the second pivot member is above the axis when the roof is in its raised position, and the first pivot member is forwardly of and the second pivot member is rearwardly of the axis when the roof is in its lowered position.
Claim 8
Dependent Claim
50 words
The invention defined in claim 1 wherein the crop-receiving body includes a rear door mounted for swinging movement into and out of closing relation with the rear of the body, and including means connecting at least one of the rear cranks with the door for controlling swinging of the latter.
Claim 9
Dependent Claim
