Definitions

• a conveyor in particular for heavy objects
• the invention concerns a conveyor of the type defined in the introductory portion of claim 1.
• the stationary means consists of two fixed beams or rails between whose upper edge a beam can be reciprocated, resting on some rollers.
• Each roller is journalled on a shaft between two wheels which can be pulled up an inclined ramp by means of rods which are mounted on the shaft.
• the upper edge of the movable beam can hereby be lifted upwardly above the fixed beams and, vice versa, be lowered between the fixed beams so as to enable trans ⁇ port in a horizontal direction of objects on the con ⁇ veyor.
• the object of the invention is to provide a conveyor of the type stated in the opening paragraph which is simpler and cheaper to manufacture and which is easy to operate.
• fig. 1 is a lateral view of the conveyor of the inven ⁇ tion, partly in the raised position shown in broken lines in which objects resting on the conveyor can be transported to the right by a rod-shaped means, partly in the lowered position shown in solid lines in which the rod-shaped means of the conveyor may be moved backwards to the left without said objects being move ,
• figs. 2 and 3 show a section of the conveyor in the lowered and raised positions, respectively.
• figs. 4 and 5 show a vertical cross-section of fig-. 2 and fig. 3, respectively.
• the conveyor shown in the drawing comprises a cross- sectionally U-shaped stationary means 1 whose opening faces upwardly.
• the means 1 contains a rod-shaped means 2 which is connected to a rail 4 by means of a plurality of uniform rotatable links 3 , only one of which being shown in the drawing.
• the connection between each of the rotatable links 3 and the rod-shaped means 2 consists of a rotatable pin 5
• the connection between each of the rotatable links 3 and the rail consists of a corresponding rotat ⁇ able pin 5.
• the distance between the rotatable pins 5 in the rod-shaped means 2 is the same as the distance between the rotatable pins 5 in the rail, so that the rod-shaped means 2 and the rail 4 form two parallel sides of a parallelogram, whose other sides are the rotatable links 3 or more particularly the distance between the two rotatable pins 5 in each link 3.
• Stop means are provided to limit the movement of the parallelogram connection when the rod-shaped means 2 is displaced longitudinally with respect to the rail 4.
• These stop means are provided by forming the rotat- able links 3 as parallelogram-shaped plates, as shown in figs. 1, 2 and 3. In one extreme position which is shown in fig. 3 and in which the rod-shaped means 2 is raised with respect to the rail 4, the two parallel sides of the links 3 engage the rod-shaped means 2 and the rail 4, and in the other extreme position which is shown in fig. 2 and in which the rod-shaped means 2 is lowered with respect to the rail 4, the two other parallel sides of the links 3 engage the rod-shaped means 2 and the rail 4.
• This parallelogram connection consisting of the rod- shaped means 2, the rail 4 and the connecting rotatable links 3 is journalled in the bottom of the stationary means 1, so that the parallelogram connection 2, 3, 4 can be moved horizontally to the right or to the left in fig. 1.
• this parallelogram connection is provided with wheels 6 whose shafts 7 are secured to the rail 4 or, as shown in the drawing, to the part of the rotatable links 3, which is close to the rotat- able pin 5 of the link 3 in the rail 4 so that the height of said shafts 7 above the bottom of the sta ⁇ tionary means 2 is constant or nearly constant.
• the shafts 7 may also be secured to one of the rotatable pins 5 which connect the rail 4 with a parallelogram- • shaped plate.
• Displacement in a horizontal direction of the rod-shaped means 2 with respect to the rail 4 is obtained by means of the handle 8, which is shown in fig. 1 and which may simultaneously be used for displacing the paral- lelogram connection 2, 3, 4 horizontally in the sta ⁇ tionary means 1.
• slide blocks instead of the wheels 6, slide blocks might be used, which are capable of taking up greater loads than the wheels 6.
• Two or more conveyors may be placed in mutual spaced and parallel relationship, and the objects may be posi- tioned so as to rest on several conveyors simultaneously.
• These conveyors arranged in parallel may be positioned between guides (not shown) preventing the transported objects from falling down at one or the other side of these parallel conveyors.
