APPARATUS FOR OPERATING A PIVOTED MEMBER Filed June 26, 1953 2 Sheets-Sheet 1 March 27, 1956 ORR 2,739,484-
APPARATUS FOR OPERATING A PIVOTED MEMBER Filed June 26, 1953 2 Sheets-Sheet 2 .w/wsw United States Patent APPARATUS FOR OPERATING A PIVOTED MENBER John Hewitt Orr, Coventry, England, assignor to Carbodies Limited, Coventry, England Application June 26, 1953, Serial No. 364,396
Claims priority, application Great Britain August 14, 1952 4 Claims. (CI. 74-99) The invention relates to an apparatus for reversibly moving, between extreme positions, a pivoted member (e. g., an arm of a mechanism for raising and lowering a window or a foldable head of a motor car) about its pivotal axis.
According to the invention, the apparatus includes a bell-crank lever pivoted from the member on a parallel axis and having one of its arms connected to be acted upon by a double-acting hydraulic piston and cylinder arrangement, the other arm of the bell-crank being connected by a link to a stationary part which the member approaches (or recedes from, as appropriate) during the pivotal movement, the said other arm and link having coacting means for preventing the said arrangement from relatively moving them in one direction beyond an over centre position corresponding with one of the extreme positions of the member, and the link becoming orientated, by movement of the said other arm in the reverse direction, to arrest the reverse movement when the member reaches its other extreme position.
For avoiding any reverse movement of the piston and cylinde arrangement when the said other arm and link move from an aligned position to the over centre position, the connection of the link to the stationary part can be by a pin and slot, the slot being of a suflicient length to accommodate the change in the effective combined lengths of the said other arm and link when moving from the aligned to the over centre position.
In the drawings, which illustrate an embodiment of the invention applied to a pivoted window of a motor car body:
Figure l is a side elevation, with parts broken away for disclosing the apparatus, of a mid-portion of a motor car body;
Figures 2 and 3 are enlarged side elevations of the apparatus and respectively showing the latter operated to the positions in which the window is closed and fully open; and
Figure 4 is a section, to an enlarged scale, on the line 4-4 of Figure l.
In Figure l is shown a portion 11 of a motor car body provided with a sector-shaped window 12 which is pivotally supported at 13 in rear of a door 14. The window includes a frame 15 which works in a guiding groove of the body, and fast with the bottom member of the frame (e. g., by weldingnot shown) is a channel member 16 in which works a roller 17 at the top of a pivoted member 13, a stub axle 19 for the roller extending outwardly between in-turned lips 20, 20 at one lateral side of the channel member.
The pivoted member 18 is part of a mechanism for raising and lowering the window and, when the latter is closed, extends generally upwardly, having a pivotal connection 21 at its foot with a stationary part (e. g., a bracket 22 fast with the motor car body (as shown)).
An unequal bell-crank lever (see Figures 2 and 3) is pivoted at 23 to the member 18 remotely from the pivotal connection 21, and its longer arm 24 is pivoted at 25 to 2,739,484 Patented Mar. 27, 1956 "ice one end of a link 26. i The other end of the latter has a laterally-extending pin 27 working in a slot 28 (shown very much exaggerated for the sake of clearness) of the bracket 22, and the pin has a locating nut 29 on its extending end. The arm 24 of the bell-crank lever has a lateral projection 30 forming an abutment for the link for holding them in an over centre position, as shown by Figure 2, in which they extend more or less at rightangles from the pivoted member 18 when the window is closed. In fact, the arm 24 and the link 26 form'a toggle of which the common pivot'25 can just pass over centre in the one extreme position, as shown by Figure 2.
A piston and cylinder arrangement 31, 32, which is approximately parallel to the arm 24 and link 26 when the window is closed, is pivoted at 33, at one end, to the bracket 22 and at 34, at its other end, to the shorter arm 35 of the bell-crank lever.
Conveniently, and as shown, the bracket 22 has flanges by which it is made fast, as by spot welding, to internal flanges 36 and 37 of the body.
For opening the window the piston and cylinder arrangement is contracted and this turns the bell-crank lever for folding its longer arm 24 and the link 26 towards each other in the direction away from their over centre position, to the position shown in Figure 3. In the latter it will be seen that when the window is fully opened the link and the arm 24 are approximately at right-angles to each other, and the link thus prevents further rotation of the bell-crank by the piston and cylinder arrangement.
It will be seen that by the invention the pivoted member 18 can be operated to either extreme position and that the pin and slot connection 27, 28 enables the link and arm 24 to pass over centre without involving any accommodating reverse movement of the piston and cylinder arrangement. Moreover it will also be seen that if leakage of the hydraulic fluid should occur, or its temperature change, the piston and cylinder arrangement cannot move correspondingly when the pivoted member 18 is in either extreme position, owing to the locking eifect of the bell-crank and link.
What I claim as my invention and desire Letters Patent of the United States is:
1. The combination with a member which is pivoted on a stationary part and is movable between extreme positions, of a bell crank lever pivoted upon the member about an axis parallel to the pivotal axis of the member, a hydraulic device of the piston and cylinder type which is pivoted at one end to one arm of the bell crank lever and is pivoted at the other end to said stationary part, the other arm of the bell crank lever being pivoted at its end to a link which is pivoted upon the said stationary part by means of a pin and slot connection which will allow the said other arm and link to pass over centre when the hydraulic device is moving said member to one extreme position without the hydraulic device having to reverse to accommodate such movement, and means for limiting the extent to which said other arm and said link can pass over centre, said other arm and link being substantially parallel to said hydraulic device when moved over centre as aforesaid, and being substantially at rightangles to one another in the other extreme position of said member whereby to limit the movement of said member towards said other extreme position.
2. The combination with a member which is pivoted on a stationary part and is movable between extreme positions, of a bell crank lever with long and short arms pivoted upon the member about an axis parallel to the pivotal axis of the member, a hydraulic device of the piston and cylinder type which is pivoted at one end to said short arm of the bell crank lever and is pivoted at the other end to said stationary part, said long arm of the bell crank lever being pivoted at its end to a link to secure by which is. pivoted upon. the. said stationary part, and means for limiting the extent to which said long arm and said. link can pass over centre.
