Title: Loaders of the dipper type
IPC: E02F3/34
Filed: 1948-03-25
Abstract: 649,935. Load-handling machines vehicle fittings for loading. DEMPSTER BROS., Inc. March 25, 1948, No. 8796. Convention date, May 13, 1947. [Classes 78 (iii) and 78 (iv)] [Also in Group XXI] In a shovel-type loader, the shovel is pivoted to an arm swinging about an upstanding member carried by a frame, and has also a pivotal connection with a boom pivoted on the frame and raised and lowered by fluid pressure means. As applied to a rear end loader on a vehicle a frame 11 secured to chassis 10 provides a pair of tracks on which run the rollers 12 of a carriage 13, which is moved along the tracks by a horizontal ram 14. An upstanding member 16 is pivoted to the carriage and is supported at a desired inclination by bracing 17. An arm 30 supports the shovel 33 pivotally from the upstanding member and the shovel is fixed at a desired inclination to the arm by means of short arms 39 pivotally connected by one of several holes between the shovel and the arm. A pair of boom arms 21 are interconnected by a transverse member 22 and pivoted at 20 to the frame 11. A ram 26 is pivotally connected between the transverse member and the frame and the end of the boom is pivotally connected through a pair of rigid rods 36 to the shovel. The shovel can be swung by ram 26 to the chain line position or slightly beyond. The rear wall 43 of the shovel is pivoted by means of bars 44 to the shovel so that it opens. The wall 43 is normally locked shut by a latch bar 48, Fig. 3, engaging a catch member 53 on the shovel and pressed home by a spring 55. On raising the shovel a cable 57 secured to the upstanding member below the pivot of arm 30 is tautened so that its other end secured to a lever 50 pulls this so as to withdraw the latch bar 48 and release the rear wall 43, so dumping the shovel contents. On removing the shovel and arms 30 and 36, the machine becomes a self-loading vehicle of known type whereby a load suspended from the end of the boom is raised up the skidway formed by the upstanding member at its rear position on frame 11, the upstanding member then being moved by ram 14 forwardly whereupon the load swings forward and may be lowered on to inclined frame members 19. In a modification as a front end loader on a tractor the upstanding member is directly pivoted to the front end of the tractor frame and its upper end is moved to vary its inclination by a ram connected between the upper end and an upstanding bracket at the rear of the frame. The shovel supporting arm 30 is curved outwardly at its upper end so that the shovel is digging parallel with the ground when still forward of the upstanding member ; suitable adjustment of the short arms 39 for altering the shovel inclination thus allows the shovel to dig downwardly during the initial swinging if desired.

This is fixed on the spindle 6 and co-operates with the adjacent roller 14 to form a path for the light beam passing from the lens tube 3 to a photo-electric cell 76. The roller 7 is freely rotatable on the spindle 6, and is acted upon by a spring 9, so that the flange of the roller bears lightly on the edge of the film 15. The film is fed forward by continuously driven sprockets 18, 19, and is held tightly against the rollers 7, 14 by a tensioning roller 20. The optical system, with focusing and slit adjusting means, is described in Specification 351,472. Figs. 4, 5 and 6 show a modification in which the film passes, where the light beam is projected through it, over a pair of rollers 44, 49, the intervening space 16 forming a light aperture. The roller 44 has a spirally-grooved surface, and is also provided with sprocket teeth 45 engaging the film, while the roller 49 has a flange 48. The spiral urges the film towards the flange 48, and also serves to keep the film free from dirt. A shaft 43, on which the roller 44 is fixed, is driven by means such as a pulley, which may serve as a flywheel. Above and below the rollers 44, 49 the film 15, is guided by rollers 58, 64, and an idler 70, as shown in Figs. 5 and 6. The roller 64 is mounted on a fixed pin 63, being urged towards a stop collar by a spring 67. This spring is located in a cup 52 which forms a bearing for a three-armed member. One arm 57 of this member carries the film-tensioning roller 58, a second arm 54 being connected to a spring 55, while the third, 59, forms a pointer which indicates when the film has been correctly threaded and tensioned.
