BOTTOM DOOR CATCH Filed March 17, 1934 NVENTOR. Abram Paul A TTORNEYS.

Patented Jan. 15, 1935 UNITED STATES PATENT OFFICE BOTTOM DOOR CATCH Application March 17, 1934, Serial No. 716,059

Claims.

This invention relates to improvements in bottom door catches of a type to prevent rattling of the doors when closed.

The major object of this invention is to provide a novel and improved form of structure by means of which folding or sliding doors on vehicles may be firmly held while closed to prevent vibration thereof, and to prevent the production of the noises incident to such vibration when the vehicle is in motion.

The many objects of this invention which are successfully secured by the structure disclosed will be apparent from the following description.

This invention resides substantially in the combination, construction, arrangement and relative location of parts, all as will be set forth in full detail hereinafter.

In the drawing,

Fig. 1 is a top plan view of the structure showing the relative arrangement of the parts and their association with the doors;

Fig. 2 is a front elevational view thereof;

Fig. 3 is an end elevational view thereof.

A portion of the bottom forward ends of the doors is shown at 1 and 2. The platform or floor at the opening controlled by the doors is indicated at 3 in Fig. 3. Secured to the under face of the platform 3 is a plate 4 having a depending flange 5 to which a compound leaf spring 6 is attached by means of rivets 7. The form of the leaf spring is clearly shown in Fig. 1. It consists of a straight central portion having curved ends positioned for cooperation with the other parts.

Secured to the doors at the bottom and near the forward edges thereof are the pairs of plates 8 and 9 which are attached by screws 10 passing through the doors. The plates 9 are provided with threaded bosses 14 which receive the threaded ends 13 of the arms 11. The nuts 14 are provided to lock these arms in adjusted position. The arms 11 are provided with upwardly projecting extensions 15 positioned to contact the outer curved ends of the compound spring. The arms 11 are so placed that as the doors move to closed position the portions 15 of the arms 11 engage the outer curved ends of the springs. The result is that the door sections are firmly held against rattling and vibration when they are in closed position, and yet do not interfere with the normal operations of opening and closing them.

From the above description it will be apparent that this invention resides in certain principles and features of construction which may be embodied in other physical forms by those skilled in the art without departure from the spirit and scope of this invention. 5

I do not, therefore, desire to be strictly limited to the disclosure as given for purposes of illustration, but rather to the scope of the appended claims.

What I seek to secure by United States Letters 10 Patent is: I

1. The combination with a pair of door sections, of a flat spring having curved ends rigidl supported adjacent the ends of the door sections when the doors are closed, and a pair of arms mounted on the door sections and positioned to engage the curved ends of the springs when the doors close to hold the doors against movement.

2. The combination as described comprising a pair of door sections, a supporting plate mounted adjacent the edges of the door sections when in closed position, a compound leaf spring secured to said plate, and a pair of arms attached near the bottom of the forward edges of the doors so as to engage the leaf spring as the doors close to place the spring under tension.

3. A combination as described comprising a pair of doors, a leaf spring supported near the bottom of the doors whenin closed position, said spring having curved ends, sets of plates secured to the doors, and curved arms mounted on said plates having portions for engaging the curved ends of the springs when the doors are in closed position.

4. A combination with a pair of door sections, of a compound leaf spring supported below the door sections near the forward edges thereof, said leaf spring having ends curved towards the plane of the doors, and a pair of curved arms mounted near the bottom edges of the doors and positioned to engage the curved ends of the spring.

5. A combination with a pair of door sections, of a compound leaf spring supported below the door sections near the forward edges thereof, said leaf spring having ends curved towards the plane of the doors, a pair of plates on opposite sides of each door section, and an arm mounted on said plates, each arm having a portion engageable with the curved ends of the springs. 50
