Title: Improvements in or relating to machine tools, for example milling machines
Inventor: LAPPE WILHELM
IPC: B23Q15/00
Filed: 1956-03-07
Abstract: 792,884. Milling. WERNER AKT.-GES., F. March 7, 1956, No. 7167/56. Class 83 (3). A milling-machine, or other machine-tool, comprises first and second limit-switches 2, 3 having contact-pairs which are in a circuit for controlling relative movement of tool and workholders in opposite directions, and which are actuated by dogs 8-13 when movement takes place, the first of the contact-pairs 2b in the first switch 2 acting to change the movement from rapid to feed-speed in one direction and the second of the pairs 2a acting to stop the movement, similar contact-pairs 3b, 3a in the second switch acting in the same manner for movement in the other direction, a third pair of contacts 2c in the first switch 2, actuated when the movement is in said other direction to change the movement from feed to rapid speed, a similar contact-pair 3c in the second switch acting in the same way for movement in the said one direction, and a single actuating-member 7b for both switches, which is displaced by the dogs so that either only one of the first and second pairs, or both of them, or all three pairs of one switch are actuated, the control-circuit being such that the operation of the first and second pairs in the latter case has no effect on the movement. In a milling-machine having a vertically-movable knee carrying a table transversely movable on a slide, the table-movements are controlled by electric, or electromagnetically-operated friction-clutches controlling right-and-left movement, rapid traverse and feed. If movement of the table 4 is desired to the left, a move-left press-button is actuated to cause the rapidtraverse and left-movement clutches to be energized. The dog 11 then opens the contacts 3b to de-energize the rapid-traverse, and energize the feed-clutch. Feed continues until the dog 13 opens the contacts 3a to cause both direction-clutches to be energized and lock the slide. However, if the swinging dog 12 is in the position shown, it actuates the other switch (2) to cause rapid traverse to the left before the dog 13 brings it finally to rest. A series of dogs 11, 12 may provide a series of intermittent feedmovements interspersed by rapid movements. To return the table, a move-right button is pressed and the table traverses rapidly to the right until stopped by the abutment 10. If the initial movement of the table is required to be to the right, the move-right button is first pressed and the swinging dog 9 can be used for intermittent feed.

Abstract: 453,282. Excavating. EDMONDS, P. J., The White House, Itchen Abbas, near Winchester. March 8, 1935, No. 7313. [Class 68 (i)] [See also Group I] In a lifting-device for cultivators, ploughs, scrapers, &c. comprising an eccentrically mounted cam-like member adapted to be brought into contact with the ground and to roll upon it as the implement moves forward, a sprag or like extension is pivoted at the long radius end of the cam-like member to dig into the soil as this end passes its bottom dead centre position, thus returning the lifting member to its inoperative position. The cam member comprises a plain or ribbed tyre part 6 and a bracing bar 7, both of angle or T-section. It may be clamped on a sleeve 8 on the cranked axle 4 of the travelling wheels 5. It is thrown over to engage the ground by pulling a cord 15 attached to a lever 12 carrying a spring-pawl 11 engaging a ratchet pinion 10. The pivoted sprag 13 normally hangs vertically or trails behind in the inoperative position. As the cam member is thrown over the sprag 13 swings into contact with the stop 14 and afterwards falls forward into contact with the ground and returns the cam-shaped member into inoperative position as the implement continues to move forward. The cam may be prevented from rising too far by a stop which is withdrawn upon operation of the lever 12. A spring or stop may be provided to ensure that the lever 12 returns to the position shown when the cord 15 is released. The lifting-device is such that there is no substantial rigid extension of the cam part below the cam axis in the inoperative position, and the cam is so shaped as to give a gradual and high lift.
