Abstract: 987,493. Linkwork. MAY-PRESSENBAU G.m.b.H. April 20, 1961, No. 14263/61 Heading F2K. [Also in Division B5] A lever system for a mechanical press comprises a short lever 11, Fig. 3, pivoting at one end on a stationary support 15 and at the other end 12 on a long lever 10 sliding rectilinearly in a guide 14, a connecting rod 16 transmitting drive from a crank 18 to the two levers, the stationary support 15 being adjustable in position through a range of such extent that either the levers 10, 11 never lie over one another during each revolution of the crank, Fig. 2 (not shown), or alternatively they lie over one another once per revolution, Fig. 4 (not shown), or by proceeding to the extreme end of the range, the levers 10, 11 cross-over each other twice per revolution of the crank, Fig. 12 (not shown). The rectilinear movement of the end 13 of the lever 10 can thus be adjusted so that one or two reciprocations are performed for each revolution of the crank, and the stroke may be varied. According to the invention, a press has a system of such levers connected between an input 28, Fig. 14, and a punch 23. As shown, two such systems are arranged in parallel. Each system comprises a crank drive 32, a connecting rod 33, a short lever 38 pivoting on a stationary but adjustable pivot 45 and at 35 on the connecting rod, and a long lever 39 also pivoting at 35 on the join between the short lever and the connecting rod, the remove end of the long lever 39 reciprocating in a guide slot 41 to actuate the punch 23. The pivots 45 are formed as eccentrics on discs 46, Fig. 16, rotatable in the press frame 20 and formed with square cross-section hubs forced into a coupling sleeve 50, a turnbuckle screwed on to oppositelyhanded threads 53, 54 on the disc hubs surrounding the whole. To adjust the position of the pivots 45, a tool is inserted into a hole 57 in the turnbuckle to turn the latter and release the discs 46 from clamping engagement with the press frame. A worm (not shown) meshing teeth 60 on the hub of one of the discs 46 is then turned to effect the desired adjustment, and the turnbuckle re-tightened. The discs 46 can be positively secured in position by spring- biased lock pawls engaging notches therein, Fig. 15 (not shown), and secured by safety screws.

Title: Improvements relating to locking devices for retractable aircraft undercarriages
IPC: B64C25/26
Filed: 1938-05-18
Abstract: 579,640. Retractable undercarriages for aircraft. AIRCRAFT COMPONENTS, Ltd., and BRIDGES, D. G. May 18, 1938, No. 14842. [Class 4] In a retractable undercarriage having a folding element such as a radius rod, locking means are carried on the folding element and comprise a latch and a detent carried by an articulated frame with pivotal connections to the two parts of the element in such manner that folding of the element deforms this frame and consequently shifts the detent relatively to both parts of the element, whilst unfolding of the element results in the detent being returned to a location in which the latch can engage it for locking. In the form shown, the latches are disengaged by lost motion of a retracting jack connected to the folding element. The latches 10 and 11 are hinged at 12 to a lug 4F provided on the upper part 4B of the folding element, to which the jack 5 is also connected by means of a pin 5B and slot 6. In the extended position of the undercarriage, Fig. 2, the latch 10 engages a detent 9 forming a pivotal connection between the links 7 and 8, of which the latter is adjustable in length. Upon commencement of the retracting movement of the jack, the latch 10 is disengaged by the pin 5B which then comes in contact with the upper end of the slot 6 and retraction proceeds, accompanied by folding of the parts 4B, 4c of the folding element, to the position shown in Fig. 3. The link 7 is thus constrained by the link 8 to rotate anticlockwise, taking with it the integral lever 15 and thus causing the resilient device 13B to rotate both latches clockwise and finally cause the latch 11 to engage with the detent 17, which is carried by the aircraft structure. Upon extension of the undercarriage, the latch 11 is disengaged by lost motion of the jack, and the latch 10 engaged by the device 13B. Electrical contactors 16 may be provided to indicate when the latches are home. According to the Provisional Specification, a fluid dashpot may be provided to prevent sudden movements due to disengagement of the latches.
