Abstract
693,109. Riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HENSHAW, J. N. Jan. 26, 1951 [Jan. 27, 1950], No. 2130/50. Class 83 (iv). A blind riveting machine is operated to set a rivet by the release of a compressionspring which is energized by a cocking action and constrained in the energized condition without further effort on the part of the operator, a manuallyoperable member being provided to release the constraint upon the spring and effect relative movement between deforming-member-engaging means, e.g. mandrel-gripping jaws and abutment means, by which a rivet is held up to the work. One element Y of a tool X, Y includes a handle 11 provided with upwardly. extending plates 13 which are pivoted on a pin 25 fixed between plates 23 at the rear of the other element X which includes a casing 15 for the setting mechanism. The elements X, Y are normally held at an angle of 110 degrees to one another by the engagement of spring-urged poppets 26, carried by the plates 13, with recesses in the plates 23. A helical compression spring 63, encircling a rod 65 and confined between a head 67 thereon and a seating 69 in the handle 11, is housed in a tubular member 61 which extends out of the handle. A link 75 is pivoted between opposed ears 71 at the top of the rod 65, the other end of the link 75 being pivoted on a pin 79 which bridges a groove in a rotor 77 rotatable on the pin 25. The ends of the pin 79 project beyond the rotor and each receives a toggle link 89 pivoted to a second link 93 which is pivoted to the associated plate 13. A link 83 pivoted to a member 87 connected to the usual slidable sleeve 29 housed in the casing 15 is also pivoted on a pin 81 fixed across the groove in the rotor. The leaf-springs 39 which urge apart the mandrel-gripping jaws 37 housed in the sleeve 29 are fixed to a block 41, pressed forwards by a spring 43 but normally held back by the broad end 51 of a plate 45, Fig. 3, slidable across the casing 15 and positioned by a leaf-spring 55. Initially, Fig. 1, when the tool is cocked, the spring 63 is compressed and its tendency, through the rod 65 and link 75, to turn the rotor 77 clockwise is overcome by the straight toggle 89, 93; the sleeve 29 is forward, but the block 41 is held back so that the jaws 37 are open. After insertion of a mandrel stem within the jaws, the plate 45 is manually displaced so that a narrow part 47 thereof allows spring-urged forward movement of the block 41 and hence of the jaws 37, whereupon the latter grip said stem. On pressing a trigger 99, extensions 103 of which are pivoted on opposite sides of the rotor 77 on the pin 25, the extensions thrust the upper ends of the links 93 to the rear to break the toggle. Consequent expansion of the spring 63 pulls down the rod 65 so that the rotor is turned clockwise and the sleeve 29 and jaws 37 are pulled back to set the rivet. Rearward movement of the block 41 during setting permits return of the plate 45 to its initial position under the action of its spring 55. To recock the tool the elements X, Y are swung towards one another; the rear end of the sleeve 29 having been brought into engagement with a face 109 of the casing 15, the link 83 prevents clockwise movement of the rotor 77 and hence of the pin 79, and the spring 63 is compressed, the toggle 89, 93 being progressively straightened. The elements X, Y are then returned to their initial positions in which they are held by the poppets 26, expansion of the spring 63 being prevented by the straightened toggle so that the rod 65 and link 75 rise; as a result the rotor 77 turns anti-clockwise, causing forward movement of the sleeve 29 and block 41 until the latter is halted by the plate 45, whereupon as the sleeve moves on the jaws 37 open. If the elements X, Y are returned smartly, any piece of the mandrel stem broken off after setting and remaining between the jaws 37 will be ejected. Specifications 348,818, 405,993, 459,973, [all in Group VII], 504,928, 578,104 and 587,938, [both in Group VII], are referred to.
