15 Claims.
This invention relates to lift and throwout mechanism for car doors and concerns itself more particularly with means for elevating the door with respect to its supporting rollers so that it will be supported upon such rollers for sliding movement, and for moving the lower1 end of the door outwardly to readily clear all binding or parts of the car. The means or mechanism for performing these functions is set in motion by a 1o single operation so that the door is substantially simultaneously elevated and moved outwardly.
The invention comprises the novel structure and combination of part-s hereinafter described and more particularly pointed out and defined in the appended claims.
In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views:
Figure l is a fragmentary front elevational view of a double door involving this invention illustrating the doors in their lowered positions.
Figure 2 is a view `similar to Figure l illustrating the doors in their elevated positions supported upon the rollers.
Figure 3 is a View similar to Figure 1 illustrating a modified form of actuating mechanism.
Figure 4 is a view similar to Figure l illustrating a further modified form of actuating mechanism and a modified form of roller housing.
Figure 5 is an enlarged fragmentary vertical sectional view taken upon the line V-V of Figure 1.
Figure 6 is an enlarged fragmentary sectional view taken upon the line VI-VI of Figure 1.
Figure rI is an enlarged fragmentary sectional view taken upon the line VII- VII of Figure 2.
Figure 8 is an enlarged fragmentary sectional view taken upon the line VIII-V111 of Figure 4.-,
' showing the door in elevated position.
In referring now to Figures l, 2, and 5 to 7 it will be observed that the car door l has a casting or member 2 secured to the outer face thereof at each lower corner. In referring to Figure '7, it
.415 will be noted that each casting 2 has an outwardly directed stud 3 at its inner end which engages in a slot 4 in an ear 5 on a roller housing 6. The
The lever 10 is pivoted upon a boss 1l (Figure 7) which is integral with the casting 2, which it will be noted has a forwardly extruding flange 12 upon which the boss 11 is located. The lever 10 also has an aperture 13 for receiving an arin 14 on a transversely rockable member 15 that initially elevates the door and moves the same outwardly. These rockable throw-out members have curved fulcrums that rest upon the track 17 when the door is in its lowered position with the castings 2 engaging the track as shown in Figures 1 and 5. The members 15 are supported by the casting 2 by means of knuckles 18 which extend into bearing recesses in such castings. In referring to Figure 7, it will be noted that each knuckle 18 comprises laterally extending trunnions 19,
shown in dotted lines which are journalled in suitable bearing recesses extending from the main recess. W ith this construction, it will be obvious that when the arms 14 of the door throwout members 15 are forced downwardly, the knuckles 18 will move upwardly and outwardly in arcs with the fulcrums 16 as centers and will initially elevate and swing the lower `end of the door outwardly to clear the binding and parts of the car. When the door has been elevated so that it is supported upon the rollers as will hereinafter be more fully explained, the fulcrums 16 will be elevated above the track as indicated in Figure 2.
The upper end of each plate lever 10 is pivoted to the outer end of a rod 20. The inner ends of the rods 20 are pivoted to lateral lugs 21 on a hand lever 22 which is pivoted between such lugs to a plate 23 secured to the front face of the car door.
When the hand lever 22 is swung in one direction, to the right for example as shown in Figure 2, the rods `2() will be drawn toward each other and will rock the plate levers 10 upon their pivot points 11 towards each other. As the levers 10 are thuswise rocked the arms A14 .of the door throwout members 15 will be forced downwardly and the outer ends of the roller housings 6 will likewise be forced downwardly. As the outer ends of the housings 6 are vforced downwardly, the inner ends thereof which are attached to the door will be elevated, the roller housings sliding through the instrumentality of the slotted connections e as shown in Figure 2. The lowering of the arms 14 of the Ydoor throwout members 15 will initially .elevate the door, until it is raised to such a point by the movement of the throw-out members 15 that the fulcrums no longer contact the track 17 as shown in Figure 2 when the rollers I will serve as fulcrum members to complete the elevation of `the door. The arrangement is such that the initial upward movements of the door can be more easily effected through the throw-out members than if the rollers came into play at once. It will, of course, be understood that the door will be swung outwardly before the fulcrums 16 of the door throwout members are elevated above the track so that the door is substantially simultaneously ele-- vated and thrown outwardly in one movement.
Referring` now to Figure 3, it will be noted that the roller housings and castings 2 are similar to those in the rst form and are similarly connected. The door throwout members are also similar. In Figure 3, the mechanism for actuating the roller housings 6 and the door throwout members has only been modiiied. This modified form of actuating mechanism consists of a pair of levers 24 the lower ends of which serve as the aforementioned plate levers l0. The lower ends of said levers 24. are pivoted to the bosses 1l on the castings 2 and connected to the housings 6 and door throwout members l5 in the same manner as the plate levers l0. The upper ends of the levers 24 are slotted and an operating handle 25 has a shank or the like extending through the slots with the result that when the handle 25 is forced downwardly the levers 24 will be simultaneously rocked for actuating the roller housings 6 and the door throwout members l5 for elevating the door and throwing the same outwardly in the manner previously explained. When the door has been fully elevated, the throwout members will have been elevated above the track.
In Figure 4, a further modification has been illustrated. In this instance, there are a pair of levers 26, the upper ends of which are slotted and connected by a handle 2'? substantially as in the form shown in Figure 3. The lower ends of these levers 26 are fulcrumed or pivoted upon bosses 1l upon the casting 2 which are similar to the first form described. The levers 26 are also connected to the arms 14.- of throwout members 15 similar to those in the first form. In Figure 4, the roller housings 6 are eliminated and the rollers 7 are carried directly by the levers 26 which have suitable bifurcations 28, shown in dotted lines, in which the rollers are journalled.
As the levers 26 are forced downwardly, the door throwout members 15 will be actuated thereby for initially elevating the door and for throwing the door outwardly and when the rollers 7 are brought into engagement with the track so as to serve as fulcrums further actuation of the levers will completely elevate the door and also elevate the throwout members l5 above the track. From the foregoing, it willbe obvious that a novel and readily operable mechanism has been provided for elevating oar doors and moving the lower portion outwardly for clearing the binding or parts of the car.
I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
