TRIPPING DEVICE Filed Dec. -21, 195s 2 sheets-sheet 2 WWA? Patented Mar. 5, 193.5
TRIPPING DEVICE Louis Birkigt, Bois-Colombes, France Application December 21, 1933, Serial No. 703,495 In Belgium November 9, 1933 'l Claims.
My invention relates to mechanisms for the tripping or release of movable organs subjected to the action of a high return or counter force, such as the movable part of a spring starter for internal combustion engines or the equivalent, the carriage of a spring catapult, rams or tups for driving posts, and, in a general manner, all organs that are maintained by a catch in a given position against the action of an elastic system exerting on said organs a considerable effort tending to move them from said position.
'I'he object of the present invention is to provide a mechanism of the type above referred to in which the release of the organ held by the catch necessitates a smaller effort than with the mechanisms utilized for similar purposes up to the present time.
To this effect, the mechanism according to the present invention is so devised that the catch is actuated by an intermediate tripping element arranged in such manner that its releasecauses the movable organ to be released, this intermediate element being automatically brought back into its position in which it maintains the movable 25 organ against the action of the elastic means acting thereon, when said movable organ is brought back to its initial position after having been released.
Other features of my invention will appear 30 from the following detailed description thereof.
Preferred embodiments of my invention will be hereinafter described with reference to the accompanying drawings, given merely by way of example, and in which:
Fig. 1 is a diagrammatical plan view of a rst embodiment of my invention.
Fig. 2 is a diagrammatical plan view of another embodiment.
Fig. 3 is a side elevation of the form shown in Fig. 2.
It will be assumed that the release device according to my invention is applied to a springv starter for internal combustion engines, but it similar structure, as`
'I'he starter may further comprise means (not shown in the drawings because they are not part of the invention) for bringing back the parts into their initial position, after their working, and accordingly for moving rod 1 toward the right hand side of the gure, thus compressing spring 2, until said rod is again maintained in the desired position against the action o1' said spring.
'I'he tripping mechanism according to the presl0 ent invention comprises a catch or pawl 3 intended to maintain rod 1 in the desired position against the action of spring 2 and to release it when it is desired. 'Ihis catch or pawl 3 is con- Y trolled by an intermediate element 4 so arranged l5 that its displacement in a certain direction causes the disengagement of said catch from said rod, vand therefore the release of said rod. When, subsequently, said rod is moved in a' backward direction so as to again engage it 20 with catch or pawl 3, this intermediate' element 4 is automatically brought' back into the position in which it maintains said catch engaged with said rod.
To this effect, as shown in the drawings, said 25 intermediate element is itself advantageously provided with a second catch or pawl 5 directly connected with the control means 6 so that, when said means is acted upon, element 4 may be released, that is to say left free to move with 30 respect to rod 1.
Elastic means, consisting for instance of a spring "I interposed between element 4 and the stationary part of the mechanism, are provided for moving said element 4 with respect to said 35 stationary part when the second catch is removed from the left notch in bar 1.
'Ihis element 4 and catch 3 are, according to my invention, so connected together that when element 4 is displaced by spring '7, it causes catch 40 3 to be disengaged from rod 1, thus releasing said rod.
To this effect, catch 3 may be carried by a le,- .ver 8 pivoted about a stationary axis 9 and subjected to the action of a spring 10 tending to pivot 45 it in the direction in which catch 3 releases rod 1.
As for element 4, it is mounted in slideways substantially parallel to the direction in which rod 1 is `allowed to slide.
This element 4 is provided with a cam 11 50 adapted to coact with a projection of lever 8 (for instance a roller 12) This cam is so shaped and positioned that, when element 4 is maintained in the position shown in the drawings, cam 11 maintains pawl 3 in engagement with rod 55 1. On the contrary, as soon as element 4 is released and allowed to move under the action of spring 7, cam 11 allows lever 8 to pivot under the action of spring 10, bringing catch 3 out of engagement with rod 1 which is then released.
In order that the intermediate element 4 should be automatically brought back into the position of Fig. 1 when rod 1 is moved backwards, said rod is provided with a notch 13 adapted to coact with the second pawl or catch 5.
Consequently, when said catch 5 has been disengaged and element 4 has moved under the action of spring 7, together with catch 5, pivoted to said element, it suilices to move rod 1, in a backward direction, a distance such that notch 13 comes opposite said catch (position shown in dotted lines in the drawings). Under the action of the spring acting thereon, said catch 5 penetrates into notch 13 and when rod 1 moves toward the left hand side ofthe figure a small distance (from the position of notch 13 shown in dotted lines to its position shown in solid lines) element 4 is brought back into the position shown in the drawings thus compressing its spring 7.
It will be readily understood that, with such an arrangement, it is necessary that rod 1 should be moved in a backward direction beyond the position shown in Fig. 1, being then allowed to come back to said position under the action of spring 2.
Of course, during the whole of the backward movement of rod 1, lever 8 is maintained by spring 10 in a position such that it cannot engage with rod 1. But, during the slight displacement of said rod toward the left hand side of the gure, lever 8 is caused to pivot by the action oi cam 11 on roller 12. It is therefore necessary to give notch 14, provided in rod 1, a length at least equal to the length of cam 11 measured in the longitudinal direction of element 4.
Of course, as the second catch 5 is to move longitudinally together with element 4, it is necessary to so connect it with controlling means 6 as to allow for said displacements.
In the example shown in the drawings, it will suffice, to this effect, to provide this catch 5 with a slideway 15, parallel to the direction of displacement, adapted to receive a sliding element 16 directly connected to control member 6, which moves in a direction at right angles to said slideway 15.
It will be readily understood that, with the arrangement above described, the release of rod 1 can be obtained without exerting a considerable effort and, as a matter of fact, with an effort corresponding to the release of element 4.
As shown in the embodiment of Fig. 2, it is advantageous to utilize two catches 3a and 3b symmetrically disposed with respect to a plane passing through the axis of rod l, so as to avoid any lateral effort on the guides of rod 1.
In this case it will be advantageous, as shown in Fig. 2, to provide a single intermediate member 4 for both pawls 3a and 3b. This element 4 will therefore be disposed in a plane at right angles to the plane of the two catches 3a and 3b. It will be provided with two cams 11a and 11b coacting with rollers 12a and 12b respectively.
While I have described what I deem to be preferred embodiments of my invention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition and form of the parts without departing from the principle of my invention as comprehended within the scope of the appended claims.
